A flexible package having multiple compartments is described and depicted. The package can include an internal compartment panel to define first and second package cavities or compartments. Two adjacent but opposing access openings can be provided proximate a top portion of the package to define separate access into the distinct compartments, without a need to open or remove the top or handle portion of the package.

According to the present disclosure, there is provided a container to food product (20) having a self-standing flexible pouch (22); a raw wet protein portion (14) disposed within the pouch (22); and a closure (34) sealing the pouch (22). There may also be provided a method of packaging a raw wet protein portion (14) for retail, the method comprising: opening an empty self-standing flexible pouch (22); filling the empty pouch (22) with a raw wet protein portion (14); and sealing the pouch (20).

A disposable piping bag comprising a pair of side panels having joined side edges, the bag having a substantially conical configuration, the side edges extending downward to a sealed or unsealed tip and extending upward to an opening along upper edges incorporating an integral resealable closure in the side panels. The resealable closure has corresponding and adjacent lengths of a closure having one or more mating male ribs and female sealing channels on the side panels extending along a width of the bag opening. In one embodiment, the piping bag has a configuration with a substantially frusto-conical lower portion, a substantially cylindrical mid-portion, and a substantially frusto-conical upper portion.

A tamper-evident security device to be used in conjunction with a slidable closure on a carrier bag comprises a bottom component (positioned within the bag itself) and a top component attached to a front panel of the carrier bag so to be located over the bottom component. The top and bottom components are fixed together in an immovable form, and the top component includes a recess for supporting the slider mechanism of the slidable fastener. A lid component is coupled to the top component via a hinge element, wherein upon closure of the lid component over the top component, the slider mechanism of the fastener is fully enclosed. A provided frangible seal (included to indicate possible attempts to tamper with the closure) is attached to the security device, with an end portion of the top component including a cover tab to hold the frangible seal in place as the carrier bag is handled during transport.

An embodiment includes a bag comprising mesh and film side walls and a reinforcing strip of film; wherein (a) the mesh side wall is sealed to opposing side edges of the film side wall; (b) the reinforcing strip of film is sealed to an upper portion of the mesh side wall and to the opposing side edges of the film side wall; (c) the film side wall has a bottom extension, which is monolithic with the film side wall, extending upwardly and sealed along a lateral extent of a bottom portion of the mesh side wall; (d) the film side wall is non-coplanar with a portion of the bottom extension; (e) another portion of the bottom extension is non-coplanar with the mesh side wall; and (f) a horizontal axis intersects the bottom portion of the film side wall and three portions of the bottom extension.

A longitudinal method for producing a side-gusseted bag includes providing an incision extending in a transverse direction in a bag film for each side-gusseted bag in such a way that, in the case of a subsequently formed side-gusseted tube, the incision extends over both side gussets and a first front wall that is situated between the side gussets. Proceeding from the incision, the first front wall, together with the corresponding parts of the side gussets, is folded back, on which a separate film section is placed and fastened in the folded-open region. The folded-over section is folded back in such a way that all connecting seams of the separate film section extend in parallel to each other in the transverse direction.

A thermoplastic bag includes raised rib-like elements that allow the thermoplastic bag to expand. The thermoplastic bag further includes side seals having rib-like elements that allow the side seals to expand. Additionally, in one or more implementations, the thermoplastic bag includes one or more of a material formulation, a density of raised rib-like elements, a height of raised rib-like elements, or land areas that provide the raised rib-like elements with a reduced rebound ratio.

A zipper closure for use in a package includes first and second closure strips. Each of the first and second closure strips includes at least one closure profile and a flange. The flange of the first closure strip includes outer and inner flange portions. The outer flange portion of the first closure strip encompasses and is integrally connected to the inner flange portion of the first closure strip at a bending point. The inner flange portion of the first closure strip includes the at least one closure profile. The inner flange portion of the first closure strip has a length less than the length of the outer flange portion of the first closure strip. The closure profile of the first closure strip is located between an open end of the inner flange portion and the bending point.

A reclosable package comprises a first panel having first and second side sections and a second panel having first and second side sections. The first panel opposes the second panel and is joined to the second panel along the first and second side sections. A bottom extends between the first and second side sections of the first and second panels with the first and second panels joined to each other. A mouth is disposed opposite the bottom and extends between the first and second side sections of the first second panels. A closure member extends along the mouth, with the closure member including a first fin joined to the first panel and second fin joined to the second panel. A sealing member having a first and second ends is disposed proximate the mouth. The ends of the sealing member can be attached to the fin or panel such that at least one of the first end or second ends of the sealing member is attached with peelable seal.

Device for closing the opening of a sack, in particular a sack made of flexible material, comprising a first element with hooks and a second element with hooks, the hooks (9) of the two elements engaging into one another to achieve the closure of the opening, each element with hooks comprising a base strip (7, 8) and hooks coming from the strip.
