Full mouth opening flow wrapper package

a wrapper package and full-mouth technology, applied in the direction of wrapping, sacks, transportation and packaging, etc., can solve the problems of reducing the opening size, reducing the size of the portion returned to the package, and often not satisfactorily effective zipper closure, so as to achieve positive re-closure of the package and facilitate the movement of the product into and out of the package

Benefits of technology

The patent makes a new package design that allows for better efficiency in storing and retrieving the contents. It includes a full mouth opening reclosure that helps to keep the package sealed and safe. This design makes it easier for consumers to use and enjoy the product.

Problems solved by technology

In the past, webless zipper has been used in the machine direction, but due to the size and shape of the product, the zipper closure was frequently not satisfactorily effective and not user friendly.
That is, typically, the user slices the cheese from an end of the chunk, meaning that the portion returned to the package still does not fit well.
A reclosure can be added, but this has been limited to a standard transverse direction zipper in the past, resulting in a package with an opening of a reduced size.
The process is typically complex and the machinery used to produce the box pouch is expensive.

Embodiment Construction

[0019]Referring now to the drawings in detail wherein like numerals indicate like elements throughout the several views, one sees that FIG. 1 discloses a flow wrapper machine 300 (it is likewise envisioned that a horizontal form fill and seal ‘HFFS’ machine could be used) wherein a web or film 100 made of polymeric material, is supplied by unwinding from a spool or reel 200. Reclosures or zippers 106 (typically comprising a plurality of re-engageable interlocking elements which can close upon themselves, such as, but not limited to, male and female interlocking elements) are supplied from a reel 202 and placed periodically along the web or film 100 in a transverse machine direction, and sealed or otherwise attached thereto. Alternately, the spool or reel 200 may be supplied with web or film 100 with the reclosures or zippers 106 pre-applied, either in a local or remote location with respect to the flow wrapper machine 300. In the embodiment of the flow wrapper machine 300 illustrate...

Abstract

The disclosure pertains to method for manufacturing reclosable packages, bags or pouches using a flow wrapper machine wherein, typically, a self-mating reclosure or zipper sealed inside of the package. In a first embodiment, self-mating reclosures are placed transversely on the web and a flow wrapping machine wraps the web around the food product thereby forming a machine direction fin seal. Transverse direction end seals are likewise formed. In a second embodiment, the web includes quad seals formed by a drag sealer at positions which will become corners of the package. Similar to the method of the first embodiment, the flow wrapping machine wraps the web around the food product thereby forming a fin seal.
