Abstract
A packaging device includes an expandable and collapsible tube, for receiving a product therein. The tube has a sidewall, a closed end and an open end. A closed-cell foam plug is compressible and insertable in the compressed state at least partially into the open end of the tube. Upon expanding, the foam plug closes and seals the open end of the tube.
Description
- This application claims the benefit of U.S. Provisional Patent Application No. 62/091,231, filed on Dec. 12, 2014, the entire contents of which are incorporated herein by reference in their entirety.
- The present invention is generally directed to a packaging device, and more particularly to a packaging device comprising a tube for receiving a product therein, sealable by a foam plug.
- Packaging products in some form of a collapsible tube or pouch is common practice. For example, topical formulations, e.g., gel, ointment, cream, shampoo and lotion, pharmaceutical products, cosmetic products and the like, are often packaged and sealed in a form of collapsible tube or pouch. Typically, the tube is filled with the product via an open end thereof, the open end being thereafter heat sealed with the product contained inside the tube.
- One drawback of heat sealing the open end of the tube is that the temperature at which the opposing layers of the thermoplastic tube material, e.g., polyethylene and/or polypropylene, are sealed together is often too high for a heat sensitive product within the tube. Thus, heating sealing the tube may damage or degrade the product contained therein. One approach to addressing this drawback has been to form the tube of a material which can be heat sealed at lower temperatures, e.g., Surlyn® Ionomer Resin, sold by E. I. du Pont de Nemours and Company of Wilmington, Del., in order to mitigate damage or degradation of the product. However, such materials are often not chemically compatible with the product contained in the tube, or are not recognized and/or approved by the appropriate regulatory agency.
- Therefore, it would be advantageous to manufacture an easily sealable packaging device, sealable in a manner that avoids damage or degradation to a product contained within the package, while also not running afoul of associated regulatory requirements.
- Briefly stated, one aspect of the present invention is directed to a packaging device. The packaging device comprises an expandable and collapsible tube and a closed-cell foam plug. The tube includes a sidewall, a closed end and an open end, and is for receiving product therein. The foam plug is insertable in a compressed state at least partially into the open end of the tube and is then permitted to expand to close and seal the open end of the tube.
- Another aspect of the invention is directed a packaging method comprising the steps of: (1) filling an expandable and collapsible tube with a product via an open end of the tube, (2) compressing a closed-cell foam plug, (3) inserting the compressed foam plug at least partially into the open end of the tube, and (4) sealing the open end of the tube by permitting the foam plug to expand to close and seal the open end of the tube.
- The foregoing summary, as well as the following detailed description of a preferred embodiment of the invention, will be better understood when read in conjunction with the appended drawings. For the purpose of illustrating the invention, there is shown in the drawings an embodiment which is presently preferred. It should be understood, however, that the invention is not limited to the precise arrangements and instrumentalities shown. In the drawings:
-
FIG. 1A is an elevational view of a tube of a packaging device of the present invention, depicting the step of filling the tube with a product; -
FIG. 1B is an elevational view of the tube of the packaging device ofFIG. 1A , and a foam plug of the packaging device of the present invention in an original expanded state, depicting the step of compressing the foam plug into a temporary compressed state for insertion into an open end of the tube; -
FIG. 1C is an elevational view of the foam plug ofFIG. 1B in the temporary compressed state, depicting the step of inserting the plug into the tube; and -
FIG. 1D is an elevational view of the foam plug after insertion into open end of the tube, depicting the step of the foam plug expanding and sealing the open end of the tube. - Certain terminology is used in the following description for convenience only and is not limiting. The words “lower,” “bottom,” “upper” and “top” designate directions in the drawings to which reference is made. The words “inwardly,” “outwardly,” “upwardly” and “downwardly” refer to directions toward and away from, respectively, the geometric center of the packaging device, and designated parts thereof, in accordance with the present disclosure. Unless specifically set forth herein, the terms “a,” “an” and “the” are not limited to one element, but instead should be read as meaning “at least one.” The terminology includes the words noted above, derivatives thereof and words of similar import.
- It should also be understood that the terms “about,” “approximately,” “generally,” “substantially” and like terms, used herein when referring to a dimension or characteristic of a component of the invention, indicate that the described dimension/characteristic is not a strict boundary or parameter and does not exclude minor variations therefrom that are functionally similar. At a minimum, such references that include a numerical parameter would include variations that, using mathematical and industrial principles accepted in the art (e.g., rounding, measurement or other systematic errors, manufacturing tolerances, etc.), would not vary the least significant digit.
- Referring to the drawings in detail, wherein like numerals indicate like elements throughout, there is shown in
FIGS. 1A-1D a packaging device, generally designated 10, according to the present invention. Thepackaging device 10 is adapted for sealingly packaging any of a numerous variety of products, such as, for example, without limitation, topical formulations, e.g., gel, oil, cream, shampoo, and lotion, pharmaceutical products, cosmetic products and the like. - As shown in
FIGS. 1A-1D , thepackaging device 10 comprises a pouch ortube 12, sealable by afoam plug 14. In the illustrated embodiment, thetube 12 is generally cylindrical in shape, for, example, without limitation, in the shape of a toothpaste tube, having asidewall 12 a, a closedend 12 b connecting to thesidewall 12 a at one end, and an opposingopen end 12 c (prior to sealing). However, as should be understood by those of ordinary skill in the art, thetube 12 may take the form of any of numerous different shapes, while having an opening sufficient for inserting a product into thetube 12. - In the illustrated embodiment, the
tube 12 is a flexible tube that is expandable and collapsible, defining an initial diameter D1 in the collapsed state. Thetube 12 is preferably formed of a polymeric material that is substantially impermeable to direct light and oxygen, in order to minimize degradation or damage to a product packaged within thetube 12. For example, thetube 12 may be formed of a thermoplastic material such as, for example, without limitation, polyethylene (“PE”) or polypropylene (“PP”). However, as should be understood by those of ordinary skill in the art, thetube 12 may be formed of any of numerous different materials, currently known or that later become known, providing generally the same properties for thetube 12 as described herein. Additionally, thetube 12 may be formed of a single layer of material, or multiple laminated, or otherwise bound layers, e.g., via intermediate copolymer layers. As also should be understood, thetube 12 may be appropriately sized for receiving the desired volume of product, such as, for example, without limitation, within the range of about 5 ml to about 200 ml. - Referring to the
foam plug 14, theplug 14 is formed of a closed-cell foam, such that theplug 14 is substantially fluid, i.e., gas and liquid, impermeable as should be understood by those of ordinary skill in the art, and conformable, i.e., squeezable, from a naturally expanded state (FIG. 1B ) to a temporarily compressed state (FIG. 1C ). In the illustrated embodiment, thefoam plug 14 is cylindrical in shape, to correspond with the shape of theopen end 12 c of thetube 12, as described further below. However, as should be understood, thefoam plug 14 may take the form of any of numerous different shapes, complimentary to the opening 12 c of thetube 12. In the expanded state, as shown inFIG. 1B , thefoam plug 14 defines a diameter D2 which is greater than the inside diameter D1 of theopen end 12 c of thetube 12. Thefoam plug 14 is compressible into the temporary compressed state (FIG. 1C ) to define a diameter D3 which is smaller than the diameter D1 of theopen end 12 c of thetube 12, in order to insert thefoam plug 14 into theopen end 12 c of thetube 12, as described further below. - The
foam plug 14 is generally formed of the same or substantially the same material as the inner surface of thetube 12, thereby avoiding undesirable interaction between thetube 12 and thefoam plug 14 when theplug 14 is inserted into theopen end 12 c of thetube 12. For example, if the inner surface of thetube 12 is formed of PE, then thefoam plug 14 is formed of PE, and if the inner surface of thetube 12 is formed of PP, then thefoam plug 14 is formed of PP. Accordingly, thetube 12 and thefoam plug 14 have substantially the same melting point. - In use, the
foam plug 14 is initially unattached from thetube 12, and thetube 12 is filled with a product via theopen end 12 c thereof, as shown inFIG. 1A . Thereafter, as shown inFIGS. 1B and 1C , thefoam plug 14 is compressed into a compressed state, such that the diameter D3 of theplug 14 is at least slightly smaller than the diameter D1 of theopen end 12 c of thetube 12, and thefoam plug 14 is inserted at least partially into theopen end 12 c. Preferably, thefoam plug 14 is inserted to a depth into thetube 12 at least equivalent to the diameter (or width) D1 of theopen end 12 c to ensure an appropriate fluid-tight seal sufficiently resistant to inadvertent opening. Once inserted into theopen end 12 c of thetube 12, as shown inFIG. 1D , thefoam plug 14 naturally returns to substantially the original expanded state thereof, thereby elastically stretching theopen end 12 c of theflexible tube 12 to define a diameter D4 of theopen end 12 c substantially equivalent to (but preferably at least slightly less than) the diameter D2 of thefoam plug 14 in the expanded state. Thus, theplug 14 exerts a circumferential, radially outwardly directed force onto thetube 12, and thetube 12 exerts a circumferential, radially inwardly directed force onto theplug 14, forming a substantially fluid-tight compression seal between theopen end 12 c of thetube 12 andfoam plug 14. - For removing the product from the sealed
packaging device 10, thefoam plug 14 must be pulled out from thetube 12 with sufficient force to overcome the compressive force between thetube 12 and plug 14. Thereafter, thefoam plug 14 may be compressed and re-inserted into thetube 12 in the same manner as described above to re-seal thetube 12. Alternatively, thefoam plug 14 may be permanently sealed in theopen end 12 c of thetube 12 and theclosed end 12 b of thetube 12 may contain, for example, a removable and resealable cap, to allow access to the product. - In some embodiments, adhesive, or some other such material, may be applied around the exterior of the
foam plug 14 prior to insertion into thetube 12, such that a substantially fluid-tight seal therebetween is formed both by the adhesive attachment of theplug 14 to thetube 12 and the compression seal. In some embodiments, thetop portion 14 a of thefoam plug 14 that remains external to thetube 12 after insertion of theplug 14 may also be heated to sealingly join with thetop edge 12 d of theopen end 12 c of thetube 12, thereby minimizing heat delivery to the product contained within thetube 12 and avoiding damage thereto. - It will be appreciated by those skilled in the art that changes could be made to the embodiment described above without departing from the broad inventive concept thereof It is understood, therefore, that this disclosure is not limited to the particular embodiment disclosed, but it is intended to cover modifications within the spirit and scope of the present disclosure as defined by the appended claims.
