  • Publication number: 20210068213
    Abstract: A system includes a first unit configured to generate and apply radio frequency (RF) energy to a load positioned in the first unit during a first time period, wherein the load is at a first temperature at a start of the first time period and at a second temperature different from the first temperature at an end of the first time period, and a second unit configured to receive the load at the second temperature and to cause heat transfer by convection to the load during a second time period different from the first time period, wherein the load is at a third temperature at an end of the second time period. First and second time periods together is less than or equal to a time period for the load to change from the first temperature to the third temperature from convective processing and without application of the RF energy.

  • Publication number: 20160340099
    Abstract: A packaging container for pourable food product comprises a first side having a material laminate structure, a first and second transversal seal and a longitudinal seal extending from the first transversal seal to the second transversal seal. An opening device on the first side of the package comprises a tab portion on an outer surface coupled to an opening strip portion via a bridge penetrating through the material laminate structure to rupture the material of the packaging container to create an opening. The opening strip portion is attached on the inner surface and extends along a substantial portion of the transversal dimension of the first side.

  • Patent number: 7059487
    Abstract: A collapsible, semi-rigid container includes neck and bottom wall portions and a peripheral side wall extending between the neck and bottom wall. The side wall includes a rigid upper portion and a flexible lower portion. The lower portion of the side wall collapses into the upper portion reducing the internal volume of the container.

  • Patent number: 6106757
    Abstract: A lid (1) made of a thermoplastic material for covering an open upper end (42) of a container (40). The lid (1) comprising a lid body (10) with an opening (11) for dispensing and a pull cap (20) having a cap portion (21) to reclose the opening (11) and a pull tab portion (22) integrally formed with the cap portion(21). The opening (11) is covered by a gas-barrier film (23) sealed to a lower surface of the lid body (10). The cap portion (21) is sealed to the gas-barrier film (23) and a clearance (25) is provided between the opening (11) and the outer periphery (15) of the cap portion (21). A method of manufacturing the lid involves inserting the gas-barrier film into a mold cavity, injecting a thermoplastic resin into the cavity to form the lid body, while still warm the molding is removed. After removal, the molding can be thermally shaped along its periphery to form a flange (12) for mounting to a container.

  • Patent number: 6102236
    Abstract: A beverage container lid (1) includes a lid body (10) and a pull cap (20) that are both made of thermoplastic resin. The lid body is provided with an opening (11) for discharging contents from the container when the lid is mounted on a beverage container (40). The pull cap (20) includes a cap portion (21) and a pull tab portion (22) that are connected to one another. The lid body is made from a laminate that includes an easy-peel layer and a gas-barrier layer. The easy-peel layer forms an outermost layer of the lid body. The opening (11) in the lid body (10) is covered with a gas-barrier film (15) and the film is bonded to the peripheral portion (14) of the lid body surrounding the opening (11). The lower surface of the peripheral portion (23) of the cap portion (21) is removably attached to the upper surface (13) of the lid body (10) through the gas-barrier layer (15).

  • Patent number: 5642606
    Abstract: A sealing apparatus for packaging containers includes an anvil (23) for supporting a sealing fin portion (21), a horn (35) composed of a columnar portion and a converging portion (35b), and means for pressing said sealing fin portion (21) against the anvil (23) through the tip of the horn (35) and for transmitting ultrasonic vibration to the sealing fin portion (21). Ultrasonic vibration is transmitted to the packaging material through the horn (35) so that each pair of opposing sealant layers is fused and sealed. In addition, means for absorbing ultrasonic vibration is disposed between the tip of the horn (35) and an edge portion (25) of the sealing fin portion (21) so that ultrasonic vibration is absorbed. When the ultrasonic vibration is transmitted to the sealing fin portion (21), the sealing fin portion (21) is excited to transmit the vibration toward the edge portion (25).
