Integral Handled Layflat Thermoplastic Bag

View page
US Patent:
55734898, Nov 12, 1996
Filed:
Dec 22, 1993
Appl. No.:
8/172368
Inventors:
Carl R. Letendre - Fairport NY
Earle R. Powell - Jacksonville IL
Assignee:
Tenneco Plastics Company - Evanston IL
International Classification:
B31B 2386
B31B 2314
US Classification:
493194
Abstract:
A thermoplastic bag structure and a method for forming handle-containing bags in roll-form. The method includes the steps of forming a continuous collapsed tube; forming pairs of closely spaced seals transverse to the tube at bag length distances apart; forming a transverse line of weakness between each pair of seals; simultaneously or thereafter folding the marginal edges of the tube inwardly toward each other; forming and removing a cut-out region at one end of each sealed segment of the tube so that on removal of the cut-out region, the cut defines loop handles and a bag mouth region in each bag; again folding the marginal edges of the tube inwardly toward each other; and convolutely winding the structure to form severable bags on a roll.

US Patent:
56833407, Nov 4, 1997
Filed:
Feb 23, 1995
Appl. No.:
8/392645
Inventors:
William P. Belias - Fairport NY
Edward M. Bullard - Rochester NY
Carl R. Letendre - Fairport NY
Assignee:
Tenneco Plastics Company - Evanston IL
International Classification:
B31B 2302
US Classification:
493195
Abstract:
There is provided a thermoplastic film bag having at least two integral members that facilitate opening the bag. The bag is manufactured from a flattened tube of thermoplastic material which may be distinctively severed along independent phase shifted sinusoidal oscillating paths down the center of the collapsed tube. The bag may have two opposed tie members which are offset from the vertical center axis of the bag and from each other. The tie members may be grasped and pulled apart to facilitate the easy opening of the bag. The tie members may then be tied together to form a strong member by which the bag may be picked up and carried. In alternate embodiments the shape of the integral tie members can be modified to create a bag having only the easy open feature with no tie members. A method for making the bag is also described.
