Definitions
- This invention pertains to containers with stackable tops and bottoms.
- Sealing containers are well known in the art. They are used to organize and store items, such as perishable foods. The sealing capabilities of these containers help to protect the contents of the container from exposure to elements of the environment surrounding the container including dust, for example.
- Sealable containers may be made of various materials and formed at various thicknesses to meet a user's needs. For example, some sealable containers are durable and meant for repeated usage, but can be expensive. Other sealable containers are extremely thin and inexpensive such that they are both affordable and disposable, but not durable. Finally, some plastic sealable containers are designed such that they are a suitable thickness to provide durability and yet are inexpensive enough for a consumer to dispose after limited or extended use, if desired. Additionally, organized storage of empty sealable containers as they exist in the art can be problematic because the container tops do not securely stack within each other.
- the invention provides a container comprising a container bottom and a container top.
- the container bottom defines a cavity and includes a container bottom closure portion.
- the container top defines a cavity and includes a container top closure portion, a first nesting portion disposed along the perimeter of the container top cavity, and a second nesting portion disposed along the perimeter of the container top cavity.
- the container bottom closure portion may be connected to the container top closure portion to seal the plastic container.
- the first nesting portion and the second nesting portion make contact with the container bottom at two different portions of the container bottom.
- the invention also provides a container top defining a cavity.
- the container top comprises a locking portion disposed along the perimeter of the cavity for engaging an adjacent plastic container top and a receiving portion disposed along the perimeter of the cavity for receiving a locking portion of an adjacent plastic container top. If a first adjacent container top is inserted into the cavity, the locking portion engages a receiving portion of the adjacent container top to form a stack of container tops. If the container top is inserted into the cavity of a second adjacent container top, the receiving portion of the container top is engaged by a locking portion of the second adjacent container top to form a stack of container tops.
- the invention further provides a container top defining a cavity, which comprises an inward curved portion disposed along the perimeter of the cavity, an outward curved portion disposed along the perimeter of the cavity, and a nesting portion disposed along the perimeter of the cavity. If a first adjacent container top is inserted into the cavity, the inward curved portion is in contact with an outward curved portion of the first adjacent container top and the nesting portion is in contact with a nesting portion of the first adjacent container top to form a stack of container tops.
- the outward curved portion of the container top is in contact with an inward curved portion of the second adjacent container top and the nesting portion is in contact with a nesting portion of the second adjacent container top to form a stack of container tops.

- the container 100 comprises a container top 102 and a container bottom 104.
- the container top 102 and container bottom 104 may be connected to one another forming a seal.
- the container is preferably made of a plastic material, however, one of ordinary skill in the art would recognize that other materials may be used.
- the container bottom has a bottom surface 106, a sidewall 108, and a closure portion 110.
- the sidewall 108 extends upward from the bottom surface 106 to define a cavity for storage.
- the closure portion 110 extends outward and above the sidewall 108.
- the bottom surface 106 may have a recessed portion 112.
- the container top 102 may include a decorative portion 114 on a top surface 116.
- the recessed portion 112 shown in Figure 2 may be used, by way of example and not limitation, for accommodating a decorative portion 114 on a top surface 116 of a container top 102 when stacked on another container 100.
- the container bottom 104 may be approximately quadrilateral in shape.
- the invention is applicable to other container shapes as well, including but not limited to circular, for example.
- the container top 102 has a top surface 116, a sidewall 118, and a closure portion 120.
- the sidewall 118 extends downward from the top surface 116 to define a cavity.
- the closure portion 120 extends outward and below the sidewall 118.
- the container 100 may be sealed by disposing the container top 102 near the container bottom 104 and applying a force.
- a release tab 122 may be provided such that a user has a surface to grasp when exerting force to separate the respective closure portions 120, 110 of the container top 102 and container bottom 104.
- the top surface 116 may have a recessed portion 124 surrounded by a stabilizing rim 126 for stabilizing a container 100 stacked above the container top 102.
- the container top 102 may also have some form of decorative portion 114. As shown in FIG. 5, the container top 102 may be approximately quadrilateral in shape. One of ordinary skill in the art would recognize, however, that the invention is applicable to other container shapes as well, including but not limited to circular, for example.
- FIG. 6 shows the container top 102 in an inverted position. When inverted, the cavity defined by the top surface 116 and sidewall 118 now faces upward instead of downward. In the inverted position, the container top 102 may be used as a plate or bowl.
- FIGS. 7 and 8 show a container top 102 attached to a container bottom 104.
- the container top 102 has a container top closure portion 120.
- the container top closure portion 120 comprises an outward extending portion 128, an outward curved portion 130, an inward curved portion 132, and an upturned graspable portion 134.
- the container bottom 104 has a container bottom closure portion 110.
- the container bottom closure portion 110 comprises an outward extending portion 136, an outward curved portion 138, an inward curved portion 140, and a downward turned graspable portion 142.
- the respective closure portions 120, 110 flex slightly enough for the inward curved portion 132 of the container top closure portion 120 to slide past the outward curved portion 138 of the container bottom closure portion 110 to seal the container 100.
- the outward extending portion 128, the outward curved portion 130, and the inward curved portion 132 of the container top closure portion 120 is disposed adjacent to the outward extending portion 136, the outward curved portion 138, and the inward curved portion 140 of the container bottom closure portion 110, respectively.
- the cavity defined by the top surface 116 and sidewall 118 of the container top 102 accommodates overstuffing the container 100 by providing extra storing room for materials stacked above the sidewall 108 of the container bottom 104.
- the respective graspable portions 134, 142 may be used to grab or hold the container 100, and may also be used to help pull the container top 102 away from the container bottom 104.
- a plurality of containers 100a, 100b may be stacked on top of one another to form a container stack 170.
- the bottom surface 106a of the container bottom 104a of the superjacent container 100a rests within the recessed portion 124b of the top surface 116b of the container top 102b of the subjacent container 100b.
- the stabilizing rim 126b on the top surface 116b of the subjacent container 100b helps to limit lateral movement of the superjacent container 100a, thereby helping to stabilize the stack.
- the stabilizing rim 126b also helps to center the container stack 170 such that the center of gravity of the container stack 170 remains relatively centered to prevent tipping.
- a user will know when the container stack is not centered properly because the bottom surface 106a of the superjacent container 100a will extend beyond the outside of the stabilizing rim 126b of the subjacent container 100b, or the stabilizing rim 106a of the subjacent container 100b will cause the superjacent container 100a to rest at an angle.
- the container top 102 may be inverted and placed within the cavity of the container bottom 104 to accommodate under stuffing the container bottom 104.
- the cavity defined by the top surface 116 and the sidewall 118 of the container top 102 accommodates the storage of materials within this cavity.
- the container 100 has two areas for storage.
- the container top 102 may be used to store potato chips and the container bottom 104 may be used to store dip.
- the dip is protected by the container top 102.
- she can simply remove the container top 102.
- the inverted container top 102 and container bottom 104 are in contact at a plurality of portions. Having a plurality of portions of contact enhances the stability and sealing capability of the container top 102 in the inverted position. As seen in FIG. 11, by way of example and not limitation, when the container top 102 is in the inverted position, the container top 102 makes contact with the container bottom 104 at two portions 148, 150 to help keep dust and other objects out and preserve the contents stored in the container bottom 104. A first portion of contact 148 occurs between a first nesting portion 172 disposed along the perimeter of the container top 102 and the sidewall 108 of the container bottom 104.
- a second portion of contact 150 occurs between a second nesting portion 174 disposed along the perimeter of the container top 102 and approximately near the intersection of the outward extending portion 136 of the closure portion 110 of the container bottom 104 and the sidewall 108 of the container bottom 104.
- One of ordinary skill in the art would recognize that the relative position of the portions of contact could occur at different portions of the container top 102 and container bottom 104 than those depicted in the figures, and the number of portions of contact need not be restricted to two.
- the ability to invert the container top 102 also provides the additional functionality of being able to stack containers at two different heights. For example, as shown in FIG. 12, a superjacent container 100c rests within the cavity of the container top 102d of the subjacent container lOOd reducing the effective stacking height. This stacking arrangement may be desirable if the user wants to reduce the stacking height, and the user does not need the extra storage space provided by the container top 102d in the upright position. [0046] As shown in FIG. 13, the container top 102, shown inverted, has a locking portion 158 disposed along the perimeter of the cavity and a receiving portion 160 disposed along the perimeter of the cavity. As shown in FIG.
- a plurality of container tops 102a, 102b, 102c may be stacked on top of one another to form a container top stack 156.
- the locking portion 158b of the second container top 102b engages a receiving portion 160a of the first container top 102a to form a container top stack 156.
- the locking portion 158 comprises a protruding rib and the receiving portion 160 comprises a recessed groove.
- the locking portion 158 may include one or more of the following features to enable engagement; convex portions or ribs, concave portions or ribs, linear or curvilinear undercuts, linear or curvilinear cross-sections, discreet snap elements or buttons, interference fits, textured surfaces, or elements that modify surface friction or tackiness at or around the point of engagement.
- the engaging areas that create a locking condition may be continuous about the perimeter of the cavity or discreetly segmented about the perimeter of the cavity. It may be beneficial to design the locking portion 158 of the top 102 so as to have tactile and audible feedback upon engagement of the locking portion 158. Additional container tops 102 may be added to the stack 156.
- the receiving portion 160b of the second container top 102b is engaged by a locking portion 158c of the third container top 102c to expand the number of container tops 102 in the container top stack 156.
- the locking portion 158 of a container top 102 engaging the receiving portion 160 of an adjacent container top 102, the container tops 102 become securely attached to one another such that a user does not have to worry about the container tops 102 sliding off of each other while storing them.
- the stack of tops 156 will resist jarring and dropping and still remain locked together without vertical or horizontal displacement of an individual top 102 within the stack 156 such that stack integrity is not compromised.
- An inward curved portion 132 and outward curved portion 130 may be disposed along the perimeter of the container top 102 to provide a second portion of contact with an adjacently disposed container top 102 to further enhance stability of the container top stack 156.
- a plurality of container bottoms 104d, 104e may be stacked with a plurality of container tops 102d, 102e placed above.
- the locking portion 158e and receiving portion 16Od keeping the container tops 102d, 102e together and with the capability of the container tops 102d, 102e to fit within the cavity of the uppermost container bottom 104d with at least two portions of contact 148, 150, a large number of container tops 102 and container bottoms 104 may be stored securely in a single container top and container bottom stack 162.
- stacks of containers may also be disposed discretely adjacent to one another because the invention maintains the stacks vertically disposed in a relatively organized and centered position without leaning.
- This ability to discretely stack applies to the containers 100 regardless of whether the stack comprises a plurality of container bottoms 104 stacked within each other with container tops 102 disposed above, a plurality of containers 100 stacked with the container tops 102 in the upright position, or a plurality of containers 100 stacked with the container tops 102 in the inverted position.
- the container 200 comprises a container top 202 and a container bottom 204.
- the container 200 is similar to the container 100 in FIG. 1, however, the container top 202 does not lock together with an adjacent container top when stacked together.
- the container top 202 and container bottom 204 may be connected to one another forming a seal.
- the container is preferably made of a plastic material, however, one of ordinary skill in the art would recognize that other materials may be used.
- the container bottom 204 has a bottom surface 206, a sidewall 208, and a closure portion 210.
- the sidewall 208 extends upward from the bottom surface 206 to define a cavity for storage.
- the closure portion 210 extends outward and above the sidewall 208.
- the bottom surface 206 may have a recessed portion 212.
- the recessed portion 212 may be used, by way of example and not limitation, for accommodating a decorative portion 214 on a top surface of a container top 202 as shown in Figure 20 when stacked on top of another container 200.
- the container bottom 204 may be approximately quadrilateral in shape.
- One of ordinary skill in the art would recognize, however, that the invention is applicable to other container shapes as well, including but not limited to circular, for example.
- the container top 202 has a top surface 216, a sidewall 218, and a closure portion 220.
- the sidewall 218 extends downward from the top surface 216 to define a cavity.
- the closure portion 220 extends outward and below the sidewall 218.
- the container 200 may be sealed by disposing the container top 202 on the container bottom 204 and applying a force. To separate the container top 202 from the container bottom 204, the user may grasp the respective closure portions 220, 210 of the container top 202 and container bottom 204.
- a release tab such as 122 shown in FIG.
- FIG. 22 shows the container top 202 in an inverted position. When inverted, the cavity defined by the top surface 216 and sidewall 218 now faces upward instead of downward. In the inverted position, the container top 202 may be used as a plate or bowl.
- FIGs. 23 and 24 show a container top 202 attached to a container bottom 204.
- the container top 202 has a container top closure portion 220.
- the container top closure portion 220 comprises an outward extending portion 228, an outward curved portion 230, an inward curved portion 232, and an upturned graspable portion 234.
- the container bottom 204 has a container bottom closure portion 210.
- the container bottom closure portion 210 comprises an outward extending portion 236, an outward curved portion 238, an inward curved portion 240, and a downward turned graspable portion 242.
- the inward curved portion 232 of the container top closure portion 220 is in contact with the outward curved portion 238 of the container bottom closure portion 210.
- the respective closure portions 220, 210 flex slightly enough for the inward curved portion 232 of the container top closure portion 210 to slide past the outward curved portion 238 of the container bottom closure portion 210 to seal the container 200.
- the outward extending portion 228, the outward curved portion 230, and the inward curved portion 232 of the container top closure portion 220 are disposed adjacent to the outward extending portion 236, the outward curved portion 238, and the inward curved portion 240 of the container bottom closure portion 210, respectively.
- the cavity defined by the top surface 216 and sidewall 218 of the container top 202 accommodates overstuffing the container 200 by providing extra storage room for materials stacked above the sidewall 208 of the container bottom 204.
- the respective graspable portions 234, 242 may be used to grab or hold the container 200, and may also be used to help pull the container top 202 away from the container bottom 204.
- a plurality of containers 200a, 200b may be stacked on top of one another to form a container stack 270.
- the bottom surface 206a of the container bottom 204a of the superjacent container 200a rests within the recessed portion 224b of the top surface 216b of the container top 202b of the subjacent container 200b.
- the stabilizing rim 226b on the top surface 216b of the subjacent container 200b helps to limit lateral movement of the superjacent container 200a, thereby helping to stabilize the stack.
- the stabilizing rim 226b also helps to center container stack 270 such that the center of gravity of the container stack 270 remains relatively centered to prevent tipping.
- a user will know when the container stack 270 is not centered properly because the bottom surface 206a of the superjacent container 200a will extend beyond the outside of the stabilizing rim 226b of the subjacent container 200b, or the stabilizing rim 226b of the subjacent container 200b will cause the superjacent container 200a to rest at an angle.
- the container top 202 may be inverted and placed within the cavity of the container bottom 204 to accommodate under stuffing the container bottom 204.
- the cavity defined by the top surface 216 and the sidewall 218 of the container top 202 accommodates the storage of materials within this cavity.
- the container 200 has two areas for storage.
- the container top 202 may be used to store potato chips and the container bottom 204 may be used to store dip.
- the dip is protected by the container top 202.
- she can simply remove the container top 202.
- the inverted container top 202 and container bottom 204 are in contact at a plurality of portions. Having a plurality of portions of contact enhances the stability and sealing capability of the container top 202 in the inverted position. As seen in FIG. 27, by way of example and not limitation, when the container top 202 is in the inverted position, the container top 202 makes contact with the container bottom 204 at two portions 248, 250 to help keep dust and other objects out and preserve the contents stored in the container bottom 204. A first portion of contact 248 occurs between a first nesting portion 272 disposed along the perimeter of the container top 202 and the sidewall 208 of the container bottom 204.
- a second portion of contact 250 occurs between a second nesting portion 274 disposed along the perimeter of the container top 202 and approximately near the intersection of the outward extending portion 236 of the closure portion 210 of the container bottom 204 and the sidewall 208 of the container bottom 204.
- One of ordinary skill in the art would recognize that the relative position of the two portions of contact could occur at different portions of the container top 202 and container bottom 204 than those depicted in the figures, and the number of portions of contact need not be restricted to two.
- the ability to invert the container top 202 also provides the additional functionality of being able to stack containers at two different heights. For example, as shown in FIG.
- the superjacent container 200c rests within the cavity of the container top 202d of the subjacent container 20Od reducing the effective stacking height.
- This stacking arrangement may be desirable if the user wants to reduce the stacking height, and the user does not need the extra storage space provided by the container top 202d in the upright position.
- the container top 202 shown inverted, has an inward curved portion 232, an outward curved portion 230, and a nesting portion 264 disposed along the perimeter of the cavity.
- a plurality of tops shown inverted, may be stacked on top of one another to form a container top stack 256.
- the outward curved portion 230a of the first container top 202a is in contact with the inward curved portion 232b of the second container top 202b and the nesting portions 264a, 264b of the first and second container tops 202a, 202b are in contact with one another.
- the contacting portions may include one or more of the following features to enable engagement; interference fits, linear cross-sections, curvilinear cross-sections, textured surfaces, or elements that modify surface friction or tackiness at or around the point of engagement.
- the engaging areas that create a contacting condition may be continuous about the nesting portion or discreetly segmented about the nesting portion.
- Additional container tops 202 may be added to the stack 256. For example, if the second container top 202b is inserted into the cavity of a third container top 202c, the outward curved portion 230b of the second container top 202b is in contact with the inward curved portion 232c of the third container top 202c and the respective nesting portions 264b, 264c of the second and third container tops 202b, 202c are in contact with one another.
- FIGS. 31 and 32 for efficient storing and stacking, a plurality of container bottoms 204e, 204d may be stacked with a plurality of container tops 202d, 202e placed above.
- container tops 202d, 202e together and with the capability of the container tops 202d, 202e to fit within the cavity of the uppermost container bottom 204d with at least two portions of contact 248, 250, a large number of container tops 202 and container bottoms 204 may be stored securely in a single container top and container bottom stack 262.
- Several stacks of containers may also be disposed discretely adjacent to one another because the invention maintains the stacks vertically disposed in a relatively organized and centered position without leaning.
- This ability to discretely stack applies to the containers 200 regardless of whether the stack comprises a plurality of container bottoms 204 stacked within each other with container tops 202 disposed above, a plurality of containers 200 stacked with the container tops 202 in the upright position, or a plurality of containers 200 stacked with the container tops 202 in the inverted position.
- the invention may be applicable to thin disposable containers, inexpensive durable disposable containers, and non-disposable reusable containers.
- One of ordinary skill in the art would also recognize that the invention could be utilized with a variety of other container types.
- the invention could be utilized with such containers as storage crates, pots and pans, and beverage containers.
