Definitions
- the present disclosure relates to a sealed container. More particularly, the present disclosure relates to a hermetically sealed container, such as a hermetic cosmetic compact container.
- compact containers hold cosmetics including makeups such as powders, cherries, eye shadows, eyeliners, lip-colors, or other beauty aids.
- a base section of many compacts often includes a metal pan for containing cosmetics.
- the cosmetics can be directly stored in a cavity in the base section.
- Some compacts are arranged as a one-piece unit so that one hand opens and holds the compact, while the other hand applies the cosmetic to the skin surface of the face.
- some compact containers include a lid or a cover section hingeably coupled to a base or a container section. Either the cover section or the base section can be pivoted about the hinge to obtain the closed configuration of the compact, thereby providing a convenient storage device.
- Cosmetic containers may also be in the form of a container with a screw-on cap.
- a screw-on cap design the user must contend with two separate pieces, which can make applying the cosmetic a difficult task. For example, the user must unscrew the cap and place it somewhere so that one hand can hold the container that stores the cosmetic, while the other hand is free to apply the cosmetic to the skin surface of the face. The user has to either hold the cap when applying the cosmetic or lay the screw-on cap somewhere during the process of applying the cosmetic.
- a separate cap also increases the probability for the cap to be misplaced or lost. Without the screw-on cap, the unused portion of the cosmetic remaining in the container will dry, harden and crack, generally resulting in a product of deteriorated quality. As a result, the user incurs additional expense by having to purchase replacement cosmetic.
- screw-on cosmetic containers Another problem with existing screw-on cosmetic containers is that a user may not be aware that the screw-on cap is not properly closed, e.g., screwed on the container. If the cap is not properly placed on the container, more air flow will be permitted allowing volatiles to escape. This likely results in a low-quality cosmetic that is dried, hardened, and/or cracked.
- Some containers require complicated mechanisms to create a hermetic seal. For example, instead of a seal being created substantially between two surfaces, some cosmetic containers utilize the interaction of numerous surfaces and angles to create a hermetic seal. Some containers further require some type of curve or bend along portions of the sealing surfaces to create a “snap-fit” to secure a container in a closed configuration. Accordingly, a significant amount of force is often required to open and close certain cosmetic containers.
- the present disclosure relates to a cosmetic container.
- the cosmetic container comprises a first section including a first interface and a second section for holding a cosmetic substance.
- the second section includes a second interface.
- One of the first interface and the second interface comprises a groove and the other of the first and second interface comprises a peripheral rim.
- the groove is defined by a peripheral wall and a peripheral edge, the peripheral wall comprising a first surface angled towards the peripheral edge.
- the cosmetic container may include an outer body coupled about the first section and second section.
- the first section and the second section may be integral and joined by a living hinge. Other coupling devices may be used.
- the present disclosure further relates to a container for containing articles.
- the container comprises a first section and a second section.
- the first section is capable of engaging the second section to form a hermetic seal.
- the first section has a first cavity that is surrounded by a first peripheral wall and a peripheral edge.
- the first peripheral wall has a first surface that is angled toward the peripheral edge.
- the second section has a second peripheral wall capable of sliding between the first peripheral wall and the peripheral edge to form the hermetic seal.
- the container may include a fist end on the first peripheral wall wherein the first end is angled with respect to the vertical axis.
- the peripheral wall may be made from a substantially flexible plastic material.
- the present disclosure further relates to a method of making a cosmetic container.
- the method comprises providing a first section including a first interface and providing a second section for holding a cosmetic substance.
- the second section includes a second interface.
- the method also comprises providing a groove on one of the first interface and the second interface and providing a peripheral rim on the other of the first interface and the second interface.
- the groove is defined by a peripheral wall and peripheral edge.
- the peripheral wall comprises a first surface angled towards the peripheral edge of the peripheral rim.
- the peripheral wall may be flexible and the first interface and the second interface may be circular.
- the present disclosure further relates to a container for cosmetic material comprising a means for containing at least one cosmetic material within a container that may be selectively configured between an open position and a closed position, and a means for providing at least one interface capable of creating a hermetic seal when the container is in the closed position, the interface having an angled surface.
- the present disclosure further relates to a container comprising a first section and a second section.
- the first section is capable of engaging the second section to form a hermetic seal.
- the first section has a cavity for containing a substance comprising a volatile compound or a product comprising a volatile component contained therein.
- the cavity is surrounded by a first peripheral wall and a peripheral edge, the first peripheral wall having a first surface that is angled toward the peripheral edge.
- the second section has a second peripheral wall capable of sliding between the first peripheral wall and the edge to form a hermetic seal.
- the first and second sections may be integral and joined by a living hinge.

Abstract
Description
- The present disclosure relates to a sealed container. More particularly, the present disclosure relates to a hermetically sealed container, such as a hermetic cosmetic compact container.
- Various sealed containers or cases exist for storing and holding different types of contents. Many of these containers are designed for holding contents which are volatile and evaporate or dry quickly when left exposed. Examples of such volatile contents include moistened wipes, cosmetics, water, and/or other solvent based products. In the cosmetic industry, manufacturers are attempting to make a hermetic cosmetic container because the cosmetic contents often contain a volatile chemical component that requires hermetic storage to prevent or inhibit drying, hardening, and cracking of the components.
- In general, compact containers hold cosmetics including makeups such as powders, crémes, eye shadows, eyeliners, lip-colors, or other beauty aids. A base section of many compacts often includes a metal pan for containing cosmetics. Alternatively, the cosmetics can be directly stored in a cavity in the base section. Some compacts are arranged as a one-piece unit so that one hand opens and holds the compact, while the other hand applies the cosmetic to the skin surface of the face. For example, some compact containers include a lid or a cover section hingeably coupled to a base or a container section. Either the cover section or the base section can be pivoted about the hinge to obtain the closed configuration of the compact, thereby providing a convenient storage device.
- Cosmetic containers may also be in the form of a container with a screw-on cap. With a screw-on cap design, the user must contend with two separate pieces, which can make applying the cosmetic a difficult task. For example, the user must unscrew the cap and place it somewhere so that one hand can hold the container that stores the cosmetic, while the other hand is free to apply the cosmetic to the skin surface of the face. The user has to either hold the cap when applying the cosmetic or lay the screw-on cap somewhere during the process of applying the cosmetic. A separate cap also increases the probability for the cap to be misplaced or lost. Without the screw-on cap, the unused portion of the cosmetic remaining in the container will dry, harden and crack, generally resulting in a product of deteriorated quality. As a result, the user incurs additional expense by having to purchase replacement cosmetic.
- Another problem with existing screw-on cosmetic containers is that a user may not be aware that the screw-on cap is not properly closed, e.g., screwed on the container. If the cap is not properly placed on the container, more air flow will be permitted allowing volatiles to escape. This likely results in a low-quality cosmetic that is dried, hardened, and/or cracked.
- Another problem with existing cosmetic containers is that some containers require complicated mechanisms to create a hermetic seal. For example, instead of a seal being created substantially between two surfaces, some cosmetic containers utilize the interaction of numerous surfaces and angles to create a hermetic seal. Some containers further require some type of curve or bend along portions of the sealing surfaces to create a “snap-fit” to secure a container in a closed configuration. Accordingly, a significant amount of force is often required to open and close certain cosmetic containers.
- Thus, there is a need for an improved container that is inexpensive and simple-to-use while being capable of effecting a hermetic seal. Further, there is a need for an improved hermetically sealed compact container that can be manufactured as a one-piece unit and can be simply opened and closed. Further, there is a need for an improved hermetically sealed container that does not require complicated closing mechanisms involving multiple surfaces or “snap-fits” to lock the container in a closed configuration.
- It would be desirable to provide a container having any one or more of these or other advantageous features.
- The present disclosure relates to a cosmetic container. The cosmetic container comprises a first section including a first interface and a second section for holding a cosmetic substance. The second section includes a second interface. One of the first interface and the second interface comprises a groove and the other of the first and second interface comprises a peripheral rim. The groove is defined by a peripheral wall and a peripheral edge, the peripheral wall comprising a first surface angled towards the peripheral edge. The cosmetic container may include an outer body coupled about the first section and second section. The first section and the second section may be integral and joined by a living hinge. Other coupling devices may be used.
- The present disclosure further relates to a container for containing articles. The container comprises a first section and a second section. The first section is capable of engaging the second section to form a hermetic seal. The first section has a first cavity that is surrounded by a first peripheral wall and a peripheral edge. The first peripheral wall has a first surface that is angled toward the peripheral edge. The second section has a second peripheral wall capable of sliding between the first peripheral wall and the peripheral edge to form the hermetic seal. The container may include a fist end on the first peripheral wall wherein the first end is angled with respect to the vertical axis. The peripheral wall may be made from a substantially flexible plastic material.
- The present disclosure further relates to a method of making a cosmetic container. The method comprises providing a first section including a first interface and providing a second section for holding a cosmetic substance. The second section includes a second interface. The method also comprises providing a groove on one of the first interface and the second interface and providing a peripheral rim on the other of the first interface and the second interface. The groove is defined by a peripheral wall and peripheral edge. The peripheral wall comprises a first surface angled towards the peripheral edge of the peripheral rim. The peripheral wall may be flexible and the first interface and the second interface may be circular.
- The present disclosure further relates to a container for cosmetic material comprising a means for containing at least one cosmetic material within a container that may be selectively configured between an open position and a closed position, and a means for providing at least one interface capable of creating a hermetic seal when the container is in the closed position, the interface having an angled surface.
- The present disclosure further relates to a container comprising a first section and a second section. The first section is capable of engaging the second section to form a hermetic seal. The first section has a cavity for containing a substance comprising a volatile compound or a product comprising a volatile component contained therein. The cavity is surrounded by a first peripheral wall and a peripheral edge, the first peripheral wall having a first surface that is angled toward the peripheral edge. The second section has a second peripheral wall capable of sliding between the first peripheral wall and the edge to form a hermetic seal. The first and second sections may be integral and joined by a living hinge.

FIG. 1 , when an external downward force is applied, such as, by hand, to coversection 12 to effect pivotal motion in a direction towardbase section 14, compact 10 achieves a closed configuration. When aseparate cover section 12 andbase section 14 are employed, compact 10 achieves a closed configuration as the two pieces are brought together. It may be desirable for compact 10 to emit the traditional snapping sound associated with the closing of a conventional compact. Openinginterface 16 can also be configured to perform a latching operation for compact 10. Although compact 10 is shown in a quadrangular shape, other geometries, such as oval, circular, hexagonal, and so forth, can also be used. - With reference to
FIG. 2 , compact 10 is shown in an open configuration.Compact 10 further includes a two-piece insert 22.Insert 22 preferably includes afirst section 24 coupled to asecond section 26. As shown in the illustrated embodiment,first section 24 ofinsert 22 is pivotally coupled tosecond section 26 via aliving hinge 28.

According to a preferred embodiment,peripheral rim 36 is integral with (e.g., continuous) withperipheral surface 34. This may be accomplished by a molding process. InFIG. 4 , theperipheral rim 36 circumferentially extends above asurface 35 ofsecond section 26. According to an exemplary embodiment, peripheral rim melds into a terminal, outwardly-protrudinglip 38. According to various other embodiments,lip 38 is optional.Cavity 32 is preferably configured to hold the color-fast cosmetic.

In this embodiment, the first section includes agroove 48, although in other embodiments, the second section may include thegroove 48. Thegroove 48 is defined between aperipheral edge 33 ofcavity 30 andperipheral wall 44.Groove 48 is configured to receiveperipheral rim 36 wheninsert 22 is in a closed configuration (e.g., whenfirst section 24 engages second section 26), desirably effecting a hermetic seal.Insert 22 may not require a clasp or fastener to sustain a closed configuration because the hermetic seal may be designed to maintaininsert 22 in the closed configuration -
FIG. 5 shows the bottom perspective view ofinsert 22. The perimeter offirst section 24 andsecond section 26 is defined by a continuousperipheral rim 50 that overhangs in the direction towardexternal surfaces Rim 50 can be utilized to secure or snapinsert 22 withinsections Rim 50 is preferably configured to span a height of about 0.05 to about 0.5 inches. Other embodiments may not include this feature. - In one embodiment, when in the fully extended configuration, insert 22 spans a length of approximately 2-12 inches, having a respective approximate 1-6 inch length for both
first section 24 andsecond section 26. Alternatively, insert 22 can have other dimensions complementary to fit any sized compact 10. - With reference to
FIG. 6 , a cross-sectional view ofinsert 22 in the fully extended configuration is shown, taken about line 6-6 ofFIG. 4 . Livinghinge 28 is shown fully extended andcavity 30 andcavity 32 both appear in an empty state.Lip 38 is shown protruding outwardly fromperipheral rim 36. With reference tofirst section 24,groove 48 appears betweenperipheral wall 44 andperipheral edge 33. - Both
FIGS. 7A and 8A are enlarged, partial cross-sectional views of different aspects ofinsert 22. More specifically,FIG. 7A shows an enlarged, partial cross-sectional view ofperipheral rim 36.FIG. 8A is an enlarged, partial cross-sectionalview showing groove 48 disposed betweenperipheral wall 44 andperipheral edge 33.FIG. 8A further shows thatperipheral wall 44 terminates in afree end 45. - In one embodiment, the height of peripheral rim 36 (
FIG. 7A ) is sufficient to fit within thegroove 48. For example, in a commercial embodiment,peripheral rim 36 may have a height of about 0.1 to 0.5 inches, preferably about 0.12 inches, with a width of about 0.02 to 0.1 inches, preferably about 0.035 inches.Groove 48 is defined by multiple surfaces and components includingperipheral wall 44,surface 64, andperipheral edge 33. The total area ofgroove 48 is determined by the measurements and dimensions of these components. - Peripheral wall 44 (
FIG. 8A ) may have a height of about 0.03 to 0.2 inches and a thickness of about 0.01 to 0.03 inches. According to a preferred embodiment,peripheral wall 44 has a height of approximately 0.07 inches and a thickness of approximately 0.016 inches. Afree end 45 ofwall 44 may be angled about 10 to 60 degrees with respect to the vertical axis. According to a preferred embodiment,free end 45 is angled at a 30 degree angle with respect to a vertical axis. Thesurface 49 ofwall 44 borderinggroove 48 may be angled towardgroove 48 about 5 to 25 degrees, and more desirably 10 to 20 degrees. According to a preferred embodiment,surface 49 is angled towardgroove 48 at an angle that is approximately 14 degrees with respect to the vertical axis. Asurface 51 may be at any angle or parallel to the vertical axis. - Alternatively, other dimensions can be used. For example, this disclosure contemplates various shapes for surface 64 (e.g., curved, rectangular, triangular, etc.). Accordingly, the given dimensions and descriptions are exemplary only and do not limit the scope of the claims.
- The closing and opening of
insert 22 is discussed as follows. In one embodiment, insert 22 is closed by applying a downward force, such as, by hand, tofirst section 24 to effect a pivotal motion offirst section 24 towardsecond section 26. More specifically, as a result of the applied downward force onfirst section 24, hinge 28 folds to closefirst section 24 ontosecond section 26. - In the process of closing
insert 22,groove 48 receivesperipheral rim 36 betweenperipheral wall 44 and peripheral edge 33 (FIGS. 4, 6 , 8A, and 9A), thereby effecting a hermetic seal at the interface (FIG. 9A ). The seal can be formed betweenperipheral rim 36 andperipheral wall 44 and/orrim 36 andedge 33. According to a preferred embodiment, the distance between a first point and a second point ofsurface 49 ofperipheral wall 44 is no less than the distance between a corresponding first point and a corresponding second point ofperipheral surface 34 ofperipheral rim 36. For example, as illustrated inFIG. 4 , the distance betweenpoints 47 onsurface 49 may be greater than or equal to the distance between twocorresponding points 43 onperipheral surface 34. Moreover,peripheral wall 44 biasesperipheral rim 36 againstperipheral edge 33.Peripheral rim 36 thereby fits intogroove 48, thus securing the hermetic seal and optionally maintaininginsert 22 in the closed configuration. - The angle of
surface 49 towardgroove 48 creates an improved hermetic seal. Asrim 36 is moved intogroove 48, rim 36 first makes contact withfree end 45 andchamfer edge 52. The angled shape offree end 45 and the curved shape ofchamfer edge 52direct rim 36 into position for placement withingroove 48. Asrim 36 continues to push upward againstfree end 45,wall 44 begins to move outward away fromgroove 48. The angle ofwall 44 helps create biasing force betweenrim 36 andwall 44 that maintains a hermetic seal. - Once
rim 36 is positioned withingroove 48, the angle ofwall 44 provides enough tension to keeprim 36 ingroove 48.Compact 10 may not require a latch to maintaininsert 22 in the closed configuration. For example, the angle ofperipheral wall 44 holdsperipheral rim 36 in place to maintain the seal. Asinsert 22 obtains the closed configuration, the evacuated air may make a distinctive audible sound, indicating that the hermetic seal has been established. - To
open insert 22, a pushing or pulling force is applied, such as, by hand, tofirst section 24 in a direction away fromsecond section 26. In the process of separating or disengagingfirst section 24 fromsecond section 26 from the closed configuration ofinsert 22,peripheral rim 36 is removed from withingroove 48, thereby disrupting, e.g., breaking, the hermetic seal formed at the interface betweenperipheral surface 34 andperipheral wall 44. Asfirst section 24 is disengaged fromsecond section 26, another audible sound may be emitted, indicating the hermetic seal has been broken. Ashinge 28 unfolds,first section 24 is further moved in a direction away fromsecond section 26. - Both
FIGS. 7B and 8B are enlarged, partial cross-sectional views of another embodiment ofinsert 22. More specifically,FIG. 7B shows an enlarged, partial cross-sectional view oflip 38 extending fromperipheral rim 36.FIG. 8B is an enlarged, partial cross-sectionalview showing groove 48 disposed betweenperipheral wall 44 andperipheral edge 33.FIG. 8B further shows thatperipheral wall 44 terminates in afree end 45. - As shown in
FIG. 8B ,peripheral edge 33 includes achamfer edge 52, abulge 54 protruding in a direction towardgroove 48, and anindentation 56 pointed in a direction away fromwall 44. According to other embodiments,peripheral edge 33 may not includechamfer edge 52 and/orindentation 56. According to an exemplary embodiment,bulge 54 may extend circumferentially aroundperipheral edge 33. According to various other embodiments, one ormore bulges 54 may be located at selective locations aroundperipheral edge 33. - In one embodiment,
lip 38 may have a width of about 0.02 to 0.1 inches, preferably about 0.045 inches and a height of about 0.02 to 0.1 inches, preferably about 0.05 inches.Lip 38 may also be designed to be spherical with a radius of about 0.005 to 0.1 inches, preferably about 0.01 inches at anend 72. However, thelip 38 is not intended to be limited to such design. For example, alip 38 may have a variety of other suitable dimensions. - According to an exemplary embodiment,
bulge 54 ofperipheral edge 33 may be curved with a radius of about 0.005 to 0.03 inches. According to a preferred embodiment,bulge 54 has a radius of approximately 0.01 inches. Awall 62 associated withindent 56 may be provided at an angle in the range of about 10 to 60 degrees from the vertical axis. According to a preferred embodiment,wall 62 is provided at an angle of about 30 degrees from the vertical axis. According to an exemplary embodiment, groove 48 may have a width of about 0.025 to 0.125 inches, preferably about 0.05 inches. According to an exemplary embodiment,bulge 54 may be from about 0.03 to 0.1 inches from asurface 64 and terminates from about 0.06 to 0.25 inches fromsurface 64. According to a preferred embodiment,bulge 54 is about 0.05 inches fromsurface 64 ofgroove 48 and terminates at a distance of about 0.11 inches fromsurface 64. - Alternatively, other dimensions can be used. For example, this disclosure contemplates various shapes for surface 64 (e.g., curved, rectangular, triangular, etc.). Accordingly, the given dimensions and descriptions are exemplary only and do not limit the scope of the claims.
- In the process of closing
insert 22,groove 48 receivesperipheral rim 36 betweenperipheral wall 44 and peripheral edge 33 (FIGS. 4, 6 , 8B, and 9B), thereby effecting a hermetic seal at the interface (FIG. 9B ). The seal can be formed betweenperipheral surface 34 andperipheral wall 44 orrim 36 andedge 33. Moreover,bulge 54 ofperipheral edge 33 pushesperipheral rim 36 to biasperipheral surface 34 towardsperipheral wall 44. Even further,lip 38 ofperipheral rim 36 fits intoindentation 56 ofperipheral edge 33, thus securing the hermetic seal and maintaininginsert 22 in the closed configuration. - Once
lip 38 is positioned withingroove 48, the angle ofwall 44 provides enough tension to keeplip 38 ingroove 48.Compact 10 may not require a latch to maintaininsert 22 in the closed configuration. Asinsert 22 obtains the closed configuration, the evacuated air makes a distinctive audible sound, indicating that the hermetic seal has been established. - According to an exemplary embodiment, insert 22 (shown in
FIG. 2 ) is manufactured using an injection-molding process. A molten thermoplastic material is injected under high pressure into a mold cavity. After a cooling cycle, the plastic material solidifies, the mold opens, and the insert is ejected. Molds can be single-cavity molds, producing one part per mold cycle, or multi-cavity molds, producing multiple parts per mold cycle. The molten plastic can be injected through only one injection point in eitherfirst section 24 orsecond section 26 ofinsert 22, in which case the material flows through a livinghinge 28 into the other ofsection 24 orsection 26. According to other embodiments, each ofsections - Polypropylene is the preferred material for this application. Polypropylene has many advantages including the following: (a) it flows easily during injection and fills thin walls; (b) it forms living hinges capable of withstanding millions of cycles; (c) it is flexible enough to allow deformation during closing of the container; (d) it has a very low water-vapor-transmission-rate (MVTR), which means that weight loss of water and hydrophilic substances through the walls of the container is minimal; (e) it has very good chemical resistance to a wide range of chemicals used in cosmetic formulas; and (f) it is inexpensive. However, according to other embodiments, other types of materials may be used.
- External components of the compact (such as the cover and base) are typically also injection molded. Typical thermoplastic materials used for the external components include styrenics (e.g., acrylonitrile butadiene styrene, styrene acrylonitrile, polystyrene, medium impact polystyrene, high impact polystyrene), acrylic (polymethylmethacrylate) or other suitable resins. The main purpose of the external components is to provide stiffness to the assembled compact and provide more esthetically pleasing surfaces than can be achieved with polypropylene.
- Referring to
FIG. 10 , a cross-sectional view ofcosmetic container 110 is shown.Container 110 preferably includes afirst section 124 coupled to asecond section 126. As shown in the illustrated embodiment,first section 124 ofcontainer 110 is pivotally coupled tosecond section 126 via aliving hinge 128. According to various alternative embodiments,first section 124 andsecond section 126 may be formed separately, integrally, etc. and be either permanently or removably coupled together according to any suitable method (e.g., fasteners, moldings, screws, adhesives, etc.).Container 110 can be shaped and sized to fit within containers of various sizes.Container 110 is preferably made of resins (plastic or otherwise), including injection moldeable thermoplastic resin with relatively high flexibility, such as polypropylene (PP), polyethylene (PE), polyvinylchloride (PVC), or thermo-plastic elastomers (TPE). Alternatively, any other suitable material may be used. -
First section 124 ofcontainer 110 may optionally include acavity 130 as shown inFIG. 10 . In one preferred embodiment, a mirror can be disposed withincavity 130 for viewing the face when applying the cosmetic. Similarly,second section 126 has acavity 132 defined by aperipheral surface 134.Peripheral surface 134 includes aperipheral rim 136.Peripheral rim 136 may be attached toperipheral surface 134 according to any suitable method (e.g., fasteners, screws, adhesives, etc.). According to a preferred embodiment,peripheral rim 136 is integral with (e.g., continuous) withperipheral surface 134. This may be accomplished by a molding process.Cavity 132 is preferably configured to hold the cosmetic. Alternatively, instead ofcavity 132,second section 126 can include an aperture configured such that a pan prefilled with cosmetic can be disposed therein. Other embodiments may have alternative shaped cavities other than circular including polygonal shapes such as rectangular or square. -
FIG. 11 is a perspective view ofcontainer 110. In this embodiment, thefirst section 124 includes agroove 148, although in other embodiments, thesecond section 126 may include thegroove 148. Thegroove 148 is defined between aperipheral edge 133 ofcavity 130 andperipheral wall 144.Groove 148 is configured to receiveperipheral rim 136 whencontainer 110 is in a closed configuration (e.g., whenfirst section 124 engages second section 126), desirably effecting a hermetic seal.Container 110 may not require a clasp or fastener to sustain a closed configuration (as shown inFIG. 12 ) because the hermetic seal can maintaincontainer 110 in the closed configuration. In alternative embodiments, it may be desirable to include a bulge, lip or indentation similar to what is shown inFIGS. 7B, 8B , and 9B. Livinghinge 128 is shown fully extended andcavity 130 andcavity 132 both appear in an empty state. With reference tofirst section 124,groove 148 appears betweenperipheral wall 144 andperipheral edge 133. - In one embodiment, when in the fully extended configuration,
container 110 spans a length of approximately 2-12 inches, having a respective approximate 1-6 inch length for bothfirst section 124 andsecond section 126. Alternatively,container 110 can have other dimensions complementary to fit any sized compact. - Referring to
FIG. 13 , acontainer 210 is shown according to an exemplary embodiment.Container 210 is similar to compacts described above except thatcontainer 210 may be used to hold or contain any number of other articles requiring hermetic seals (e.g., wetwipes, chemicals, food, photographs, etc.). -
FIG. 13 showscontainer 210 in a partially open configuration according to an exemplary embodiment.Container 210 includes an exterior shell which is comprised of a top orcover section 212 hingeably coupled to a bottom member or abase section 214. In this embodiment, thetop section 212 includes a groove 248, although in other embodiments, thebase section 214 may include the groove 248. The groove 248 is defined between aperipheral edge 233 ofcavity 230 and peripheral wall 244. Groove 248 is configured to receiveperipheral rim 236 whencontainer 210 is in a closed configuration (e.g., whentop section 212 engages base section 214), desirably effecting a hermetic seal.Container 210 may not require a clasp or fastener to sustain a closed configuration because the hermetic seal can maintaincontainer 210 in the closed configuration. In alternative embodiments, it may be desirable to include a bulge, lip or indentation similar to what is shown inFIGS. 7B, 8B , and 9B. Livinghinge 228 is shown partially extended andcavity 230 andcavity 232 both appear in an empty state. With reference totop section 212, groove 248 appears between peripheral wall 244 andperipheral edge 233. Other types of containers are also contemplated. - The advantages of the containers described herein are shown in the following example. A 24-hour water weight loss test was conducted on several known cosmetic containers. To begin the test, the empty test engines were weighed. 10 grams of water was then placed in the inserts (e.g., engines). The inserts were then closed and weighed again. After that, the filled inserts were placed in a humidity-controlled oven at 50 degrees Celsius and 60 percent relative humidity. After 24 hours, the inserts were weighed again. The 24-hour weight loss in percent is calculated as follows: (initial filled weight−filled weight after 24 hours)/(initial filled weight−empty weight)×100%. The results of the test are shown in the following table:
Product 24-Hour Weight Loss (%) Manufacturer A 0.55 Manufacturer B 0.14 Manufacturer C 0.16 Disclosed Cosmetic Container 0.05-0.08
Furthermore, the disclosed cosmetic container showed a decrease in the 24-hour weight loss to about 0.02 to 0.04 percent when left in the oven over the course of about 1-2 weeks. - It is important to note that the above-described embodiments are illustrative only.
