With Vent Means Patents (Class 53/320)
  • Patent number: 6829875
    Abstract: A method and apparatus for venting a filled bottle closed by a stopper is disclosed. The venting is designed to equalize the pressure between the interior of the bottle and the atmosphere such that the stopper inserted into the filled bottle is not forced out of the bottle by excess pressure in the bottle. The venting may be accomplished by deforming the stopper in the bottle opening to form an air-outlet opening in the region sealed by the stopper and the bottle. The venting may be implemented by a squeezing device arranged on at least one side of the stopper, the squeezing device being active in a direction perpendicular to the central axis of the bottle opening.

  • Patent number: 5339595
    Abstract: An improved head is provided for an apparatus which places a stopper in the opening of a filled container. The head has a sleeve which includes an inflatable bladder for receiving the end of the filled container and for temporarily sealing the periphery of the container around the opening. A housing is disposed over the sleeve. The housing has a top surface and defines an access passage which communicates between the top surface and the inside of the sleeve. The stopper is subsequently inserted into the container through the access passage. The housing defines a chamber around the access passage, and the chamber communicates with the access passage. A conduit projects from the housing top surface in communication with the chamber, and vacuum can be drawn through the conduit.

  • Patent number: 5143236
    Abstract: According to this process, the container (2) is filled, and after filling a capsule (6) carrying a valve is fixed in a sealed manner to the neck (21) of the bottle (2), said valve consisting of a membrane (5) of elastomeric material of thickness such that that valve can become sealed again by elastic recall after having undergone aspiration in order to create a reduced pressure and/or the introduction of unreactive gas, the capsule (6) and the valve (5) remaining on the container (2) and maintaining the seal of the container (2) during storage. A top cap (4) may receive the valve (5) and contribute to sealing. The invention also relates to a packaging unit for the implementation of this process.

  • Patent number: 4889544
    Abstract: A cooler-dehumidifier-filter 3-in-one apparatus for treating compressed air, comprising an air inlet-outlet mechanism with a built-up radiator cisterns connected therebelow, having an air diffusion mechanism and an air filtering mechanism set therein to communicate with the air intake conduit so as to provide initial cooling and filtering effect; an exhausting device being made on the bottom of said air filtering mechanism to produce spiral air flow so as to dehumidfy the compressed air; the dehumidified air being to soar upward to pass through said filtering mechanism and the interlocking holes of the flange of said air diffusion mechanism to further be squeezed and diffused to cool down again; said air current being further to pass through said upwardly disposed filtering cylinder for secondary filtration; a water cooling effect being achieved by means of the arrangement of water inlet and outlet on said radiator cisterns to match the communicating pipe formed by the vertical conduits of said radiator ciste

  • Patent number: 4864799
    Abstract: This air operated plastic pail capper machine is designed to quickly and effectively push a cover onto a pail, while also pushing out any air that may be above the contents of the pail. Primarily, it consists of a base with rollers on top for easy alignment of a pail with a plate attached to a piston rod of an air cylinder, and the air cylinder is mounted to a sleeve attached to a post secured to the base of the machine. Palm operated valves are also employed to operate the machine.

  • Patent number: 4312172
    Abstract: An apparatus and method for automatically placing large plastic lids onto containers. Lids 24 are dispensed individually from magazine 11 onto slide 33. Each dispensed lid is individually retained at the bottom of the slide 33 for pickup by a container 41. The lid is urged onto the container by a pivoted roller 47 and further leveled by a roller 58 which is extended twice by a pneumatic piston to first contact a leading edge of the lid and to secondly contact a trailing edge of the lid. Thereafter a pneumatically operated lid securement means 61 comprising a convex plate 70' burps the air from beneath the lid and fully seats the lid on the container. The apparatus has various sensing means for sensing the depletion of lids from magazine 11, for sensing that a lid has been dispensed onto slide 33 and for sensing a container at the capping station. The sensing means control the various operations of the machine in proper sequence.

  • Patent number: 3938301
    Abstract: An apparatus is described for inserting separator plates into cans and tamping them into place within the can body. A plurality of insertion heads are provided each with a vacuum supply for holding one of the separator plates on its free end. The can bodies are guided in succession to the apparatus and a positioning device such as a star wheel is provided for engaging each of the can bodies and aligning each can body with the longitudinal axis of the insertion head. Relative motion is then established between the can body and the insertion head along its longitudinal axis in the proper direction to transfer the separator plate into the can body. The vacuum is then released and the can is dropped away from the insertion head.
