Piercing-type Closure Extractor Patents (Class 215/297)
  • Patent number: 8960423
    Abstract: A fillable closure is used to initiate emptying of a separately fillable capsule molded into this closure. The capsule is made oxygen-impermeable on the inside or outside with a vapor-deposited layer of silicon dioxide or metal. The volume of the capsule can be reduced through pressurization from the top, through deformation of its side walls, for cutting or rupturing a sealing foil. The capsule has an asymmetric push button with a pusher surface, a deformable front and side wall and a stable rear wall. The upper end of the rear wall forms a stationary edge, on which the pusher surface can be pivoted downward through deformation of the front and side wall. On the bottom of the pusher surface, a triangle-shaped blade is formed, which ends in a tip, and its triangle edge forming a cutting edge for piercing and cutting the sealing foil on the bottom of the capsule.

  • Patent number: 8820554
    Abstract: A vessel cap is comprised of a body mounted at a vessel inlet through which a liquid material stored in a vessel is discharged outwardly and having a certain space therein. A pressing plate is disposed in the body to be movable in upper and lower directions. A cutter is formed at an edge of a lower surface of the pressing plate in a circumferential direction for penetrating a sealing member when the pressing plate is pressed and which cuts the sealing member when the body is rotated. A hooking member downwardly protrudes at the lower surface of the pressing plate for storing the sealing member cut by the cutter in the body. A connection portion is formed between an outer circumferential surface of the pressing plate and an inner circumferential surface of the body for guiding the pressing plate to be moved in upper and lower directions.

  • Patent number: 8746476
    Abstract: A seal covering a discharge port of a container is opened without leaving superfluous elements on the container by a container closure unit which has seal-piercing knife-like elements mounted on a flexible dome-shaped base which is located to place the knife-like elements adjacent to the seal. The dome-shaped base is flexed to move the knife-like elements through the seal and then to move them outwardly toward the periphery of the seal to cut slits in the seal. The slits act as fluid passages to permit decanting of the fluid from the container. Once the seal has been opened, the dome-shaped base is removed using a pull ring and discarded. The container closure unit has a cap which is used to close the container discharge port between uses.

  • Patent number: 8646634
    Abstract: An integral inner seal opening means within a sport closure cap for containers having a cylindrical mouth opening, for which a tamper evident inner seal with a reinforced rim secures the mouth opening. The closure cap holds a plurality of protrusions, preferably three, extending towards the inner seal, each having cutting edges of which the lower one is at a smaller radius. These protrusions engage with the tamper evident inner seal, when the cap is rotated clockwise, thereby cutting off part of the inner seal rim edge and at the same time cutting three banana shape slots in the inner seal. For single serve beverage bottles with tamper evident inner seal and a sport closure, there is no need to unscrew the cap for opening the inner seal and getting access to the beverage. Initially the reinforced inner seal rim is used to prevent protrusions from accidentally opening the bottle inner seal.

The self-opening sleeve forms on its upper edge an indentation (4), which becomes smaller towards the bottom edge (6) and tapers off into the same. There are guiding means present on the outer side of the self-opening sleeve and on the inner side of the pouring spout so that the self-opening sleeve is guided downwards by rotation on the pouring spout. The indentation (4) lies partially inside the pouring spout and partially below the same after unscrewing of the cover cap and forms an air inlet channel, which results in a steady outpour of the liquid content of a combipack.

  • Patent number: 7886922
    Abstract: The invention relates to a plastic closing device comprising a bottom part, a closing cap, and a cutting ring which is mounted inside the neck of the bottom part so as to be helically movable. A driving cam (16) which is axially disposed in the closing cap acts upon the non-continuously circular cutting ring when the closing cap is unscrewed such that the cutting ring perforates and cuts through the receptacle in a helical cutting movement. The cutting ring forms a ventilating concavity (6) which cooperates with the driving cam (16). The non-circular cutting ring, the bottom side of which is provided with a sharp cutting edge extending at an obtuse angle relative to the bottom edge of said ring, performs a helical cutting movement similar to an advancing knife when the closing cap is unscrewed such that the receptacle wall is easily cut by applying a minimum amount of force because a new sharp point constantly attacks the packaging material, thus preventing shredding.
