Patent number: 6446811Abstract: A pack of self-opening serially-arranged plastic bags of the “star-seal” type defining eight superimposed wall layers in the bag. Mounting tabs form a part of top portions of each of the eight layers and are positioned in superimposed positions and each includes an aperture for mounting the tabs on a tab retaining device of a rack in a non-front-side-free manner. Each of the tabs includes a mechanism for rendering the tab detachable and providing a predetermined detaching strength. In one embodiment, each of the tabs are detachable from the rack and in another embodiment, each of the tabs are detachable from the bag. A frangible bond is formed between the rear layer and the front layer of each successive bag in the pack.Type: GrantFiled: December 27, 2000Date of Patent: September 10, 2002Assignee: Sonoco Development, Inc.Inventor: Harry B.

Each type of bag includes integrally formed front and rear walls and gusseted side walls which extend inwardly towards each other and which terminate proximate each other. The walls have top portions defining an open mouth. Each T-shirt type bag includes laterally-spaced handles extending upwardly from the mouth portion on each side of the bag. The front and rear walls and gusseted side walls of each bag are folded onto each other along a longitudinal axis of the bag to define eight superimposed layers. A seal of the star seal type secures the bottoms of the eight layers together to close each bag bottom. Superimposed detachable tabs extend upwardly from the eight wall layers at the top of each bag. Each tab includes an aperture for mounting on a tab-retaining device of a rack.Type: GrantFiled: July 23, 1998Date of Patent: August 24, 1999Assignee: Sonoco Development, Inc.Inventor: Harry B.

Patent number: 5881882Abstract: A pack of plastic bags which are preferably self-opening are adapted to be mounted on a support rack and leave no residue on the support rack when removed therefrom. The plastic bags include front and rear walls integrally joined at their sides and secured at their bottoms and defining an open mouth portion at the top of the walls. A detaching central tab is formed at the top of each of the walls and each has an aperture therein for mounting the central tabs on a tab retaining device on the rack. The tab of at least the rear wall has a structure to propagate a tear through the tab for detaching the tab from the rack while retaining sufficient strength in the portion of the tab above the mounting aperture to prevent premature tearing of the tab and detaching from the rack.Type: GrantFiled: April 22, 1998Date of Patent: March 16, 1999Assignee: Sonoco Products CompanyInventors: Wade D.
