  • Patent number: 8938860
    Abstract: A reclosable zipper is provided having first and second opposing profiles forming at least one pair of opposing flanges. The flanges have cutouts, such as notches or apertures, disposed adjacent to side edges of the profiles so as to define at least one pair of cutouts. When the profiles are sealed to opposing inner surfaces of package panels, portions of the panels seal to each other through the at least one pair of cutouts, providing a reinforcing structure to opposing ends of the zippers, thereby preventing the zipper ends from separating upon opening the package.

  • Publication number: 20140101895
    Abstract: This application describes a new, reusable device for temporarily convening the single opening of a bag into a sealable dispenser, consisting of a closing apparatus that is held shut by a latching mechanism. The closing apparatus has a nozzle that reduces the area through which the contents of the bag may be dispensed and provides an interface for a removable cap, which serves as a preservation measure for the contents of the bag. The nozzle also provides a barrier between the contents of the bag and the operator. Previously, bags were resealed through an interlocking feature of the bag, clamping, or by thermally bonding bags of fusible materials. The new device does not require any interlocking features of a bag or any specific material properties. Further, the new device is designed for repeated use, fitting a wide array of bags, contents, and applications.

In accordance with one embodiment, one of the jaws is double sided, and the clip may be assembled with either of these sides confronting the other jaw to provide different clip functions.

  • Patent number: 7062822
    Abstract: A clip comprising a pair of jaws each having an axially extending pressure surface, and resilient hinge arms hinged together from which the jaws are cantilevered for movement between a closed position in which the pressure surfaces are in facing opposition and an open position, and latch means for retaining the jaws closed. When the jaws are moved towards their closed position with a suitably thick object disposed therebetween, they will initially contact the object at a point and then rotate about that point, causing the hinge arms to stretch and thereby increase the spacing between the pressure surfaces, whereby they may be closed with a strong and relatively uniform clamping pressure about the object.

  • Patent number: 6928702
    Abstract: The closure device (121)includes a first fastening strip (130), a second fastening strip (131), and a slider (132) adapted to be slidably disposed on the fastening strips. The slider (132) facilitates the occlusion of the fastening strips when moved towards a first end thereof. A first detent (137) is located at the first end of the fastening strips. The slider (132) includes a housing having a first flexible portion (216) for engaging the first detent (137) when the slider (132) is moved to the first end of the fastening strips. The first flexible portion (216) and detent (137) prevent removal of the slider (132) from the first end of the fastening strips (130, 131) in the longitudinal X axis (102).

  • Patent number: 6925688
    Abstract: The closure device includes interlocking fastening strips. The closure device may include a slider slidably disposed on the fastening strips for facilitating the occlusion and deocclusion of the fastening strips. The fastening strips include a first color for facilitating visual confirmation of occlusion of the fastening strips. The visible indication of occlusion will be observed from the top of the closure device. If the fastening strips are properly occluded, then the first color will not be visible by viewing the top of the closure device. The first color will be observed from the top of the closure device when the bag is deoccluded.

  • Patent number: 6904647
    Abstract: A container for retaining articles includes a pliable sack and a closure attached to an opening of the sack. The closure includes a substantially flexible member having a pair of anchors and a substantially rigid member having a pair of pivotal seats. Each of the pivotal seats is adapted to receive a respective one of the anchors of the flexible member. The closure is positionable between a closed position in which the flexible member is substantially proximate to the rigid member and an opened position in which the flexible member is substantially separated from the rigid member. The closure may be configured to have a generally circular shape when in the opened position and a generally crescent shape when in the closed position. The seats may be configured to slidably receive the anchors to minimize complexity in the manufacturing process. Each of the rigid and flexible members preferably has a unitary construction to further reduce manufacturing costs.
