  • Patent number: 10239664
    Abstract: A bottom-gusseted package comprises a package body, and a bottom gusset positioned transversely of a longitudinal axis of the package body. Formation of the bottom-gusseted package is effected by positioning individual sleeves transversely of the longitudinal axis of a flexible web which forms the package body. During package formation, the flexible web is cut to form individual packages, with each individual sleeve positioned to form a bottom gusset in a respective package. Optionally, the individual sleeve portions can be configured such that when the flexible web is cut to form individual packages, and each individual sleeve is be cut to form a bottom gusset in one package, and a top sleeve portion in an adjacent package.

  • Patent number: 9896224
    Abstract: Disclosed are apparatus and methods for producing bags filled with a flowable particulate material from a continuous tube of flexible material. The apparatus includes a one-way valve application station having a valve applicator mechanism and a cutting and heating mechanism configured for movement with the bag through the apparatus. The valve applicator mechanism holds a one-way valve for insertion within the bag as the bag is moved through the apparatus. The cutting and heating mechanism is configured to be moved in unison with the valve applicator mechanism to cooperate with it to cut a vent hole in the bag at the valve and to weld the valve to the bag. Then the valve applicator mechanism and the cutting and heating mechanism are moved to apply another one-way valve to another filled bag and the bag with the valve secured thereto is sealed. The resulting sealed bag is suitable for stable palletization.

    Abstract: An intermediate product for making bag closures wherein an elongated substrate has formed on it a pair of elongated attachment lanes having complementary fastening elements to provide an attachable-detachable closure. The lanes extend parallel and are spaced apart. A perforation line is formed in the substrate between the lanes. The tape is folded by being pulled through a slot along the perforation line to place said lanes in face-to-face engagement. The product is used in a method for making bags or pouches and on a machine modified to seal partially one side of the closure to one side of the mouth of bags or pouches being made and to seal completely the other side of the closure to the other side of the bag of pouch mouth. The perforation is separated to separate the lanes and create an attachable-detachable closure. Interlocking projections can be included in the closure.

  • Patent number: 8439812
    Abstract: A machine is disclosed for securing a closure system onto a discrete pouch. The machine includes first, second and third stations. The first station is capable of advancing discrete pouches and lifting and folding a portion of a first major surface of each pouch upon itself to form a lip, and exposing an inner surface of a second major surface. The second station is capable of positioning and attaching a closure system transversely across the exposed inner surface. The closure system includes a track having first and second legs each having an outer surface. The first and second legs are joined together by an opening/closing mechanism which includes a movable member capable of being moved back and forth. The third station is located downstream from the second station and is capable of unfolding the lip and securing opposite ends of the lip to the outer surface of the second leg.

  • Patent number: 8360643
    Abstract: A package formed of a package material comprising a heat-sealable inner layer, an outer layer, and a pressure-sensitive adhesive disposed between the inner layer and the outer layer. The package may include a gusset with a center fold that divides the gusset into a first folded portion and a second folded portion. The package may further include a transverse heat-seal region extending across the gusset whereby the first folded portion is sealed to itself by mating surfaces of the heat-sealable inner layer and the second folded portion is sealed to itself by mating surfaces of the heat-sealable inner layer. The package may also include a patterned die cut formed in the heat-sealable inner layer, wherein at least a portion of the patterned die cut is adjacent to the transverse heat-seal region of the gusset so as to allow a portion of the inner layer to delaminate and expose a portion of the pressure-sensitive adhesive when the center fold is unfolded and the resealable pour spout is opened.

  • Publication number: 20120281933
    Abstract: A one-way valve is mounted over a vent hole in a flexible package to enable gases to vent. The valve has a flexible base layer, a flexible cover layer and an interposed layer of oil. Each layer has an opposed pair of side edges. The cover layer is thinner than the base layer and is secured to the base layer along respective contiguous portions of the side edges to form an openable channel. The oil layer is located in the channel between the base layer and the cover layer and over the hole to form a bond holding the cover layer on the base layer until pressure within the package causes the bond to break, whereupon the cover layer to lift ups and opens the hole valve. Methods of making the package and valve are also disclosed.
