Definitions

  • This invention relates to a flexible package having an improved reusable closure.
  • the package is provided within a stiffer protective carton. In other cases it is a heavier gauge plastic material sufficiently strong to protect the contents without an outer carton.
  • Typical of this type of package is the glassine or wax-paper or plastic film material which is used in marketing dry breakfast food cereals such as cornflakes or potato chips or the like.
  • Another typical food product is a small block of cheese sold in a clear plastic film.
  • the user opens the package, removes a portion of the contents, and then re-closes the package until used at a future time.
  • Merely folding the flexible package is generally not sufficient because of the "memory" of the material and its tendency to open by itself when on storage shelves or in a refrigerator.
  • tape-tabs are used to fasten a disposable baby diaper around the infant.
  • These tape-tabs are multi-part devices, which are applied to the movable end of the product, so that such movable end may be secured in place on another portion of the diaper.
  • the baby diaper can be considered a "package" to contain the baby.
  • Prior practice had been the use of safety pins or other non-associated closing devices, but in the more recent past the tape-tabs have been developed with a "reclosable” or “refastenable” feature that permits the diaper to be opened, the baby to be examined, and the diaper to be closed several times.
  • US-A-3 620 217 disclosed a similar fastening for disposable baby diapers, with a further improvement disclosed in US-A-3 646 937.
  • An object of the present invention is to provide a flexible package having a reusable adhesive closure.
  • Another object of the present invention is to provide a flexible package having an inexpensive attachment to hold the reclosed end of the package in place as the package decreases in size.
  • the present invention uses a closure as an adhesive member which is secured to the body of a package. It has a plurality of jaws, one of which has an adhesive surface thereon. The refolded operative end of the package can be inserted between the jaws. When the jaws are closed, the end of the package is held in place in closed position. The member is attached to the package near the non-open end thereof, so that as the package is progressively emptied and reclosed upon a lesser volume of contents, the "flap" of the package may still be inserted in the jaws of the member where it is held in place until the next opening of the package.
  • the closure may be for a flexible food package to be applied to the original package for use by the purchaser of the food product.
  • the invention can comprise flexible packages holding non-edible products which are used over a period of time, such as nails, bolts etc.
  • FIG. 1 there is shown a food package which consists of a lightweight cardboard box (10) similar to that in which cornflakes are sold in the consumer market.
  • the openable portion (12) is folded into a gable-like arrangement with the uppermost portion (13) disposed so as to be easily opened by the consumer when the top of the cardboard box (10) is opened to expose the package (11).
  • the package With the present closure, applied to the package (11), the package can be closed and the cover folded, as shown at (14) in Figure 3. This tightly-folded flap can then be tucked into the jaws of the closure (15) which is secured to the side of the package (11), generally near the lower, unopened end of the package.
  • FIGs 5 and 6 there is shown an alternative form of packaging which is often seen in the marketplace as a plastics-film wrapped block of cheese or the like.
  • This package may be shrink-wrapped or sealed in an air-­impermeable film.
  • the end (17) is opened and a portion of the contnts removed therefrom, the package is generally just folded back upon itself and held in place with a rubber band or the like.
  • one of the closures (15) is placed on the side of the package and the flap (17) can be folded back upon itself and held tightly in place by the closure (15) as shown particularly in Figure 6.
  • the closure (15) is shown more particularly in Figures 7, 8 and 9 and may, in one preferred embodiment, be an oval-shaped disc about 5 cm (2") long in its maximum dimension.
  • a plurality of such disc-like closures can be supplied on a strip of silicone release paper (18), in a manner well-known in the art.
  • the closure (15) includes a base portion (19) which may be a thin sheet such as of polyethylene, polypropylene, paper, metal foil, or the like, with an aggressive adhesive (20) on one surface thereof to support the second member (21).
  • Aggressive adhesives of this type are well-known in the art, and for this invention may be of the pressure-sensitive type, that has the necessary properties that will allow the product to stick (adhere) to the various substrates required.
  • the adhesive (20) will stick to the silicone strip (18) for transportation, sale and use in an applicator device, but when the disc is removed from the silicone strip (18) and applied to the outer surface of the packages (11) or (17), the adhesive firmly and unremovably secures the disc (19) thereto.
  • the second member (21) of the closure (15) has a shape similar to the disc (19).
  • a lower portion (22) thereof also has an aggressive adhesive on one side thereof, which securely and irremovably holds the lower portion (22) of the disc (21) to the upper surface of the disc (19).
  • the remainder (23) of the disc (21) has either a less-aggressive adhesive applied thereto, or has an adhesive applied in strips or lines as at (24), and this permits the user to peel back the portion (23) of the disc (21) away from the surface of the disc (19), as is shown in Figure 8. This opens the "jaws" of the closure.
  • the strip-type adhesive such as described in US-A-4 299 223 is advantageous because a more aggressive adhesive can be used in the areas (24). Because this material is strong in shear but weak in peel, and because only selected areas of the member (21) have adhesive thereon, it is relatively easy to peel back the jaw-portion (21) from the disc (19) up to the fold line or "hinge" line (25) which is the line of demarcation between the areas (22) and (23) on the disc (21).
  • the advantage of the above described closure is that it can be placed on the "body" of the package, rather than on the freely-moving flap portion. This permits the flap to be folded as much as is necessary to close the package (11) as the contents are progressively removed, and the folded portion of the flap can be tucked within the jaws of the closure to hold the flap tightly in place as shown in Figure 4.
  • the reclosability or resealability of the adhesive mechanism permits this opening, closing, folding and resealing to be repeated as often as is necessary to ensure that the high quality of the contents is maintained until total consumption thereof.
