  • Patent number: 5938033
    Abstract: A pack of self-opening plastic T-shirt bags for use with a bagging rack. Each plastic bag in the pack of bags has a mouth tab portion between its two upwardly extending handles, which are at the sides of the mouth of the T-shirt bags. The mouth tab portion is located on the front and rear walls in the mouth region of the plastic bags. The mouth tab portion has an aperture for receiving a retaining projection of a bagging rack. Frangible pressure bonding is formed along the perimeter of said mouth aperture. Flapless handle apertures are also formed in the handles, with frangible pressure bonds formed along their perimeter edges. Due to the frangible bonding formed between adjacent bags, as a frontmost bag is removed from the pack of bags on the bagging rack, the next bag in the pack of bags will automatically self-open into a open position for loading with merchandise.

  • Patent number: 5213145
    Abstract: A semi-automatic T-shirt bag bagging rack and bags for use therewith. The bagging rack has a stationary rear wall with two spaced apart hooks and a tab receiving member. A support base is attached to the stationary rear wall. A movable front frame member moves between a first position distant from the stationary wall and a second position adjacent thereto. The movable front frame member has an upper planar member which is substantially parallel to the stationary rear wall and has a tacky rubber sheet member affixed thereto facing the stationary rear wall. A stack of T-shirt bags having a central tab with a central tab slit and a tab tearing slit cut therethrough and "C"-shaped cuts located near the inside edges of the handles are first loaded on the bagging rack by slipping the central tab slit of the stack of bags over the tab engaging member and by looping the "C"-shaped cuts on the handles onto the hooks on the rear wall.
