摘要:
A method for the packaging of coffee in a pouch arrangement having first and second opposed panel sections, a base gusset member, a rib and trough closure arrangement constructed and arranged for selective closure of the pouch arrangement, and a gas filter arrangement oriented in one of the panel sections. The method includes filling the pouch arrangement with coffee to a first level no greater than the rib and trough closure arrangement and sealing the pouch.

A bottom-fillable, bottom-gusseted bag including a bag-forming structure having first and second opposing body panels joined along a pair of opposing transverse seals and an offset bottom-gusset extending between the transverse seals. The bag-forming structure includes an open end opposite the offset gusset. The offset gusset includes first and second gusset panels foldably connected to each other and foldably connected to the respective first and second body panels. The second gusset panel extends beyond the first gusset panel to provide a protruding trim portion. A zipper is attached between the first and second body panels along the open end. A slider is slidably mounted to the zipper for opening and closing the zipper. A transverse slit is disposed proximate to a fold line foldably connecting the second gusset panel to the second body panel and provides a fill opening through which a product can be inserted into the bag-forming structure. This bottom-gusseted bag is easy to produce and is capable of being bottom-filled while accommodating the slider for easily opening and closing the bag.

A flexible bag includes a female profile and a male profile cooperatively arranged to inhibit interlock-blockage caused by small substances. The female profile includes first and second opposing legs. Each of the legs of the female profile includes a securing head at an extended end, a base adapted for attachment to the first panel section of the bag. A neck is between the securing head and the base. At least one of the first and second legs has a plurality of portions removed to form a first series of breaks. The portions removed include the securing head and the neck. The male profile is adapted for attachment to the second panel section of the bag, and is arranged to interlock with the first and second legs. A method of constructing a flexible bag, and a method for using a flexible bag are also described.

摘要:
A vented pouch arrangement is described which comprises: first and second opposed panel sections; a base gusset member; and, a gas filter arrangement oriented in one of the panel sections. The gusset member is preferably oriented between the panel sections; along ends thereof, to form a base by which the arrangement can be stood up during use. Preferably, the arrangement is provided with a rib and trough closure arrangement extending thereacross. In this manner, opening and reclosing the bag construction, for access to material therein, is facilitated. A method for formation of such a pouch arrangement, and methods of use, are also described.

Straight zipper sections are attached to a carrier tape for attachment to the mouth end of a bag. The straight zipper sections are mounted on the continuous tape in longitudinal series orientation, or in spaced side-by-side orientation across the length of the tape. The tape in either case may be fan folded and packed into a storage or shipping container. The tape provides for closing attachment across the mouth of a bag to provide a security membrane and/or a tamper evident structure required to be ruptured to gain initial access into the bag after the zipper is opened.
摘要:
A method and apparatus for forming a tube and bag from a supply of thin thermoplastic film with the film being formed into tubular shape about a filling tube with the edges of the film brought together and joined solely by a zipper strip having reclosable pressure interlocking members thereon with the zipper strip preferably heat sealed to the film and the zipper strip having a web between the pressure interlocking members which provides a tamper-evident juncture between the edges of the film so that the web must be severed for access to the interior of a bag formed from the film, and individual bags formed from the continuous tube by filling the tube through the filling tube and cross-seaming and cutting individual bags from the continuous film tube.
摘要:
For producing a plastic film having a plastic fastener, with male and female interlockable profiles, and accessory strips, such as ribs and strips, in preparation of a reclosable plastic bag, there is provided a first forming die which extrudes the accessory strips, a separate second forming die which extrudes the fastener, a pair of nip rolls for press-bonding the accessory strips onto the surface of the film being fed in the vicinity of the first forming die, and a bonding roll for receiving the film with press-bonded accessory strips and the fastener from the second forming die placed onto the film surface such that the fastener is bonded to the surface of the film at the bonding roll by virtue of heat.

A reclosable flexible container is provided as a pouch having a front wall with an inside and an outside surface, a rear wall with an inside and an outside surface and a pouch opening. A pair of exterior closure elements are provided for mechanical interlocking with a pair of interior closure elements. A wall of the pouch is interposed between each interior and exterior closure element. The interior closure elements further have a mechanical mechanism for selective interlocking with each other so as to seal the pouch or reopen it as desired. As a result a reclosable pouch is provided without the use of heat seals or adhesives.
摘要:
A method and apparatus for extruding a film, a tape and a closure device simultaneously to produce integrated interlocking closure stock comprising (a) extruding a sheet of film onto a rotating casting roll at a rate to provide a high draw-down ratio; (b) extruding a tape to join the film on the casting roll at a rate to provide a medium draw-down ratio; and (c) extruding a closure device onto the tape as it approaches the casting roll at a rate to provide a small draw-down ratio.
