  • Patent number: 4696145
    Abstract: An automatic container stuffing apparatus and method is disclosed. The apparatus is especially useful for the insertion of two component gas generating pouches into pressurized containers of the type wherein the pressurizing gas does not come into contact with the contents of the container. The apparatus receives the pouches, performs necessary bursting operations to initiate gas pressurization, compresses the pouch into an elongate shape and inserts the pouch into a container. Two embodiments are disclosed. One embodiment receives pouches in a continuous sheet and separates the pouches from the continuous sheet prior to insertion into a container. Another embodiment receives individual separate pouches arranged in a stack extending in the longitudinal direction of a transport conveyor, thus eliminating the need to separate the pouches from a continuous sheet.

  • Patent number: 4641485
    Abstract: Container stuffing apparatus and methods are disclosed. The apparatus is especially useful for the insertion of two component gas generating pouches into containers of the type wherein the pressurizing gas does not come into contact with the contents of the container. The apparatus receives the pouches, performs necessary bursting operations to initiate gas pressurization, compresses the pouch into an elongate cylindrical shape and inserts the pouch into a container. The apparatus includes a bursting station which comprises first and second plates which move toward each other and compress a pouch received between the first and second plates to thereby burst a rupturable member within the pouch to initiate gas generation. A reciprocable latch is provided to hold the pouch in position during the bursting operation.

  • Patent number: 4611457
    Abstract: A can stuffer and method of stuffing a can with a flexible sheet product by placing the product in a generally flat receiver chamber and pushing the product edgewise to crowd the product into one edge region of the chamber by forming longitudinal folds or creases in the product to effectively reinforce and strengthen the product in the direction of the folds, and endwise ejecting or ramming the strengthened folded or creased product from the chamber into a container or can.

The apparatus receives the pouches, performs necessary bursting operations to initiate gas pressurization, compresses the pouch into an elongate cylindrical shape and inserts the pouch into a container. The apparatus includes a bursting station which comprises first and second plates having recesses which move toward each other and compress a pouch received between the first and second plates to thereby burst a rupturable member within the pouch to initiate gas generation and direct the gas generating components toward each other. A reciprocable latch is provided to hold the pouch in position during the bursting operation.

  • Patent number: 4510734
    Abstract: A fluid impervious expandable enclosed bag containing separately compartmented first and second gas generating components which, upon admixture in successive amounts, generate gas causing the bag to expand gradually from a collapsed condition to an ultimately fully expanded condition. The internal compartmentation in the bag also contains a solvent medium and a time release capsule of one of the components, thereby providing apparatus that can be mass produced and used for insertion into aerosol-type liquid product dispensing containers to provide relatively constant expulsion pressure during use.
