摘要:
Reclosable zippers for reclosable packages are disclosed. The zippers include male and female profiles. The female profiles are periodically inwardly and/or upwardly deformed in order to generate tactile and audible feedback when the zippers are opened or closed by the user. The deformation of the female profiles typically maintains the strength of the zipper.

The disclosure pertains to the a wide mouth gusseted package wherein four machine direction edge seals are formed on the film, and the zipper is applied in the transverse direction on the opposite side of the film from where the machine direction edge seals are formed. In the resulting package, the edge seals are at the exterior of the four corners of the package, and the resulting gussets can be folded inwardly or outwardly. The package may further include a sealing strip with a peel seal layer and a sealant layer whereby a hermetic package may be produced at higher production rates and lower productions costs.

The present disclosure relates to rigid or semi-rigid cartons with zipper-type reclosable elements, particularly self-mating zippers. The cartons can be formed from blanks which have a self-mating zipper on the inside of the carton. Additionally, the zipper can be attached to a flexible film which is, in turn, attached to the package.

This disclosure pertains to a forming device used in the formation of a package with a self-mating reclosure, where a single self-mating closure wraps around the periphery of the forming device, and one end of the zipper segment extends into the lap seal of the forming device. Alternatively, one or two ends of the zipper segment could extend into a fin seal. The self-mating reclosure is mounted transversely on the sheet of web or film and includes at least one crushed end proximate to one edge of the sheet of web or film. The self-mating closure may be pre-crushed, prior to attachment to the sheet of web or film, or may be crushed after the sheet of web or film is wrapped around a forming forming device or similar structure.

The present disclosure relates to a fold locking configuration for a reclosable package or bag wherein excess flange material which extends beyond the consumer graspable tab is reduced or eliminated. A patch covers an opening with upper and lower closure strips. After the patch is removed, a peel seal is opened to gain access to the contents of the package or bag. The package or bag is then folded over so that the upper and lower closure strips interengage or interlock so that the package is closed.
摘要:
A security zipper is provided, which includes a consumer side zipper pair and a product side zipper pair, where each zipper pair is capable of secure mating. Between the zipper pairs is an intermediate flange pair which is layered with an adhesive as well as an adhesive enhancer to securely connect the intermediate flange pair. A slider is provided over the consumer side zipper pair, the product side zipper pair and the intermediate flange pair which mates the zipper pairs and connects the intermediate flanges so that the zipper is securely closed. A bag is also disclosed, which includes the security zipper and a connected product side pouch. In addition, a method for manufacturing the bag is disclosed.

The disclosure relates to the attachment of polyethylene components, such as, but not limited to, zipper profiles for a reclosable package, to film made from polylactic acid. Functionalized polyolefin is laminated or co-extruded onto the polylactic acid and serves as an intermediate or tie layer for the attachment of the polyethylene components thereto.

The disclosure relates to a method and apparatus for manufacturing a package with a rigid or semi-rigid container and a polymeric or plastic header with a reclosure, such as a zipper. The rigid or semi-rigid container is typically provided in a stack of flat containers. The header is sealed, glued or otherwise secured to the containers. The container, typically inverted, is filled, and the bottom is formed by folding and sealing the bottom portion of the container.
摘要:
The disclosure relates to a zipper for a reclosable bag wherein the zipper is designed to make additional sound during operation, and further provide an increased tactile response. The zipper profile is manufactured by forming cuts in the profile, and then the profile is stretched so that the cuts become gaps. These gaps cause additional sound during operation of the zipper.
