Patent number: 4696145Abstract: 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.Type: GrantFiled: January 13, 1984Date of Patent: September 29, 1987Assignee: Enviro-Spray Systems IncorporatedInventors: Richard Schmidt, Joseph A. Pizzo

Patent number: 4641485Abstract: 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.Type: GrantFiled: December 3, 1985Date of Patent: February 10, 1987Assignee: Enviro-Spray Systems IncorporatedInventors: Richard Schmidt, Joseph A. Pizzo, Sr.

Patent number: 4611457Abstract: 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.Type: GrantFiled: March 20, 1985Date of Patent: September 16, 1986Assignee: Enviro-Spray Systems IncorporatedInventor: Norman Bittner

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.Type: GrantFiled: February 25, 1985Date of Patent: June 17, 1986Assignee: Enviro-Spray Systems IncorporatedInventors: Richard Schmidt, Joseph A.

Patent number: 4510734Abstract: 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.Type: GrantFiled: September 16, 1982Date of Patent: April 16, 1985Assignee: Enviro-Spray Systems IncorporatedInventors: Russell Banks, David J. Magid
