A package having a recloseable pour spout is disclosed, with the package including front and rear package panels which may be joined at respective side edges thereof by inwardly extending side gussets. An upper edge portion of the package is removable, including one of the side gussets, to form a pour spout for dispensing the contents of the package. A fastener strip, which can be detachably connected to itself, extends between confronting inside surfaces of the front and rear package panels, adjacent to the pour spout, whereby the pour spout can be conveniently closed after the package is initially opened. The package can include a longitudinal seal which extends from adjacent the pour spout to overlap the fastener strip. When the package includes side gussets, the package may include an arrangement of corner seals, with the corner seals at the one of the gussets at which the package pour spout is formed not extending the full length of the package, thereby desirably facilitating shaping of the package to form the pour spout. A method of forming the present package is also disclosed.

A re-sealable bag has two sides when laid flat and a bottom and an open top. The bag is made of a flexible material and has at least two wires fixed to it. The wires extend in a direction between the top and the bottom. The wires are not parallel to each other or to the sides of the bag when they are on the same side of the bag.

The present invention relates to a re-closable package configured to provide a pouring mouth when the package is opened. The top of the package is sealed by a sealing strip that comprises two seal portions of different widths and a closure extending from one end side of the package up to the wider seal portion is secured to the outer surfaces of the package walls below the narrower seal portion such as to leave an unsealed strip between the closure and the seal.

A flexible package comprising an integral snap-closure and a method and apparatus for applying the snap closure to the package is disclosed. The snap closure is arranged to enable the repeated opening and closing of a mouth of the package and includes a segmented male closure element and a segmented female closure element that are arranged to snap-fit together. A pair of optional overlay strips may be provided to obscure the male and female closure elements to provide an enhanced aesthetically pleasing package.

This invention relates to a novel device for small, extremely flexible thin film plastic bags having short flat dispenser outlets, thereby making it possible to easily grasp and squeeze it open while shearing off a tack-welded sealed outlet, and when up-ended, can, for some easy-flow products, regulate its flow; all done using only one hand; said device may be inserted within, and bonded therein to the thin film chamber walls of plastic bags having conventional simple reclosable outlets; or incorporated during the original fabrication of the thin film plastic bag, particularly those having “Zip-Loc” or equal interlocking closure joints, with the usual alignment problems; said simple device consists of a pair of nested flexible and resilient plastic curved quadrant clamps with novel guide mouth attachments which makes it possible to squeeze the thin gauge film chamber walls manually for opening and for dispensing when up-ended, which upon release of the squeeze effort, automatically self closes to form a dust tight seal; said nested clamps may be tack-welded at its outlet for protection against pilfering of contents which, upon the initial squeeze-to-open operation by the customer shears for dispensing; novel improvements for making the curved clamps more than dust tight are offered, along with closure outlets that do not require scissor cutting or so-called easy tear sealed closures.

The invention relates to a package with a roll-up re-sealing system and a process for the production of such a package, especially flexible bags. It was the object of the invention to develop a package of the generic kind described, and also a process for producing it which is suitable for the repeated sealing, storage and repeated removal of liquid, dry, powdery, granular or pelletised contents, such that the package is inexpensive to produce, meets the requirements of protecting the integrity of the product, and is user-friendly, characterised in that a package consists completely or partially of a conditioned multi-layer composite material, or that it at least has an adhesive label made from the conditioned multi-layer composite material on one package wall, beginning in the region of the opening, that the package repeatedly rolls up monoaxially, automatically and in a controlled manner, from the package opening in the direction of the bottom of the package as far as the level of the contents at any particular time and seals itself, and that the process of rolling up and sealing is implemented by the properties of the conditioned multi-layer composite material of the package or the adhesive label.

A manually operated easy to open, squeeze-to-open while lifting for pouring, self-closing spillage-free dispenser for standard gable-top milk cartons, said dispenser made from same polyethylene laminated paperboard used for making standard gable-top milk cartons formed and sealed by standard gable-top milk carton packaging machine with its clamping, compression, heating and sealing jaws, used to form and seal the original ridge line atop the roof of the gable roof portion, modified for forming and sealing the curved quadrant elongated slotted dispenser outlet, with a tamper-evident closure that can be easily removed by the tear-away indents provided.
摘要:
A flexible closure capable of closing a flexible opening. The closure is comprised of two or more strip-like elements that are oriented in a parallel series and have ends that are attached together. The strip-like elements are alternately deformed in groups of one or more to one side and then the other side of a flexible opening. The sets of groups on the two opposing sides of the opening are brought together and held together with a force, usually to create a seal. The closure may be closed in a variety of positions, including curved and straight. The flexible opening being acted upon may be attached permanently inside or outside the closure, attached removably inside or outside the closure, the closure may be placed around the flexible opening, or the closure may be incorporated into the flexible opening. The closure may be used to close such entities as flexible containers.

A leak-proof fold-top closure and bag comprise front and back sheets of flexible material joined together at lateral sides, but open on top, and a semi-rigid splint attached to the back sheet, wherein a closed configuration includes a first fold formed by folding an upper section of the sheets over the splint and a second fold formed by folding the splint and both sheets forward again to define a reverse fold of the upper section trapped between the splint and bag material, the splint and folded sheets held in place by securing means.

A snap closure for a flexible, gusseted package and a flexible gusseted packing including the closure. The package includes a mouth portion arranged to be opened to provide access to the contents of the package. The package is formed of a flexible material and includes a front panel, a rear panel, and a pair of opposed side gussets. The panels and gussets each include a top portion, which between them define the package's mouth. The package's mouth is initially sealed but arranged to be opened, e.g., peeled apart. The snap closure enables the resealing of the mouth of the package and is made up of a pair of elongated elements, one of which includes a tongue extending along the length of it. The other element includes an undercut groove extending along the length of it. The elements are arranged to be pressed together, whereupon the tongue of the one element enters the groove of the other element with portions of the panels and side gussets tightly interposed therebetween. The closure elements may be a part of the package or a separate component for use therewith. In any case when the closure is utilized it recloses the mouth of the package to preclude or minimize the ingress of air into the package.
