A tearing guide strip 23 is integrated with a base part 21a or 21b of at least one of a male member 2a and a female member 2b constituting a zipper 2 in a peelable manner to improve the tearing unsealing ability of a zipper-equipped bag provided with an interlocking type zipper enabling resealing and unsealing after the bag is unsealed.

A male belt-shaped base having a male member with a short width, and a separation strip are heat-sealed to a film. A female belt-shaped base having a female member with a long width is heat-sealed at a predetermined position so that the male portion and the female portion are at engageable positions. The film is layered and suitably sealed to form a zipper-tape bag. The film and the separation strip are cut to form a cut portion at a non-bonded region in which the film of the zipper-tape bag is not bonded, thereby forming an unsealing tab. The unsealing tab can be easily formed by simply cutting the film.

The fastening system includes first and second fastening members, each having a backing and rows of rail segments protruding from the backing. The rails segments have a base portion attached to the backing and a cap portion distal from the backing. The cap portion has a cap width that is greater than a width of the base portion. There are rows of posts protruding from the backing of at least the first fastening member. When the first and second fastening members undergo fastening, the posts bend away from the rail segments while the cap portions of the rail segments of the first and second fastening members pass by each other and then return to their original positions after the first and second fastening members are fastened. The fastening system attached to a portion of a package is also disclosed.

A bag includes a bag body defining a housing space, an elongated member provided on a first face portion of two face portions forming the bag body, and a tab. The elongated member includes an elongated tearing guide piece, a belt-shaped base provided between a second face portion and the tearing guide piece along a longitudinal direction of the tearing guide piece. The tab has an outer edge defined in the first face portion by a cutting line penetrating through the belt-shaped base and the first face portion. A protector covering the tab is provided on a side of the first face portion provided with the belt-shaped base.

A recloseable package comprises a package body having a front package panel and a rear package panel, and a pair of inwardly extending, full-length side gussets which join the front and rear package panels. The present package further includes a recloseable fastener assembly, comprising first and second mating components, wherein the fastener assembly is joined to the rear package panel by the first mating component of the assembly. By this arrangement, the contents can be placed in the package through the open mouth, which is facilitated by the provision of full-length gussets. Thereafter, the package can be closed and sealed, by which the second mating component of the fastener assembly is joined to the front package panel in a region between the inwardly extending side gussets of the package, and to the surfaces of the side gussets adjacent the rear package panel. The package includes an upper, removable portion for accessing the fastener assembly and package contents. The removable portion defines a plurality of openings in the inwardly extending side gussets to facilitate heat-sealing of the front package panel to the rear package panel through the plurality of openings. Heat-sealing in this fashion enhances the aesthetics of the package and creates a finger-grip region at the top of each of the side gussets.

A male belt-shaped base having a male member with a short width, and a separation strip are heat-sealed to a film. A female belt-shaped base having a female member with a long width is heat-sealed at a predetermined position so that the male portion and the female portion are at engageable positions. The film is layered and suitably sealed to form a zipper-tape bag. The film and the separation strip are cut to form a cut portion at a non-bonded region in which the film of the zipper-tape bag is not bonded, thereby forming an unsealing tab. The unsealing tab can be easily formed by simply cutting the film.

A consumption packet includes a bag and a dispensing arrangement. The bag includes a first bag wall and a second bag wall defining a cavity between the first and second bag walls. The bag further has an enclosable area defined at the first bag wall and a pouch opening formed within the enclosable area. The dispensing arrangement includes a sealing flap extended from the second bag wall and folded on the first bag wall to enclose the enclosable area thereof so as to seal the pouch opening by the sealing flap, wherein the sealing flap is unfolded from the enclosable area to unseal the pouch opening.

A storage bag includes a first sidewall and a second sidewall connected to the first sidewall so as to form an interior of the bag with an opening to the interior. The storage bag also includes at least one zipper profile provided adjacent to the opening to the interior of the bag. The at least one zipper profile has opposing closure elements that respectively interlock with each other. The storage bag also includes a slider with at least one opening member and at least one detent on at least one end of the bag. The at least one detent is configured to engage with the at least one opening member of the slider to provide a leak-proof end seal.

A zipper-tape bag includes a bag body and tabs each provided to an outside of the bag body at a position closer to a housing space than a zipper tape. The bag body can be easily unsealed upon disengagement of a male portion and a female portion simply by pinching and pulling the tabs in mutually separating directions. The tabs are spaced away from an opening, which is formed after a top seal is cut off, in order that the content can be taken out or put in. The content can thus be put in and taken out without problems such as adhesion of the content to the hand and contamination of the content by touching the content by hand.

A storage bag includes at least one zipper profile provided adjacent to an opening to the interior of the bag. The at least one zipper profile has opposing closure elements that respectively interlock with each other. The storage bag also includes a slider with at least one opening member and at least one detent on at least one end of the bag. The at least one detent is configured to engage with the at least one opening member of the slider to provide a leak-proof end seal.
