Thermoplastic bag

Abstract

The present invention relates to thermoplastic bag structures which are characterized by having a pair of carrying handles which are formed integrally with the bag walls, and extend upwardly from the open mouth portion of the bag. The configuration of the individual bag handles is such that there is reduced tendency for that portion of the handle which is in the user's palm, when such bags are loaded are carried, to curl into a small cross sectional area, commonly known as roping. Additionally, the individual bags are constructed so that when the bags are loaded and being carried by the user, the stress points around the bag mouth are distributed to areas which are less likely to rupture and tear as a result of stress concentration.

What is claimed is: 
     
       1. A .[.thermoplastic.]. bag structure comprising a front and rear bag wall and an open mouth top portion, said open mouth portion being characterized by having handles which are located on opposite ends of said open mouth portion, said handles being integral extensions of said front and rear bag walls, said bag being further characterized in that the upper portion of each of said handles is substantially wider than the lower portion of said bag handles said lower portions being located adjacent opposite ends of said bag mouth; said bag mouth being further characterized by having stress relief notches positioned at opposite ends of said mouth, the upper edges of said mouth extending above said stress relief notches. 
     
     
       2. A bag structure in accordance with claim 1 wherein said front and rear walls are joined together by an integral pleat portion. .Iadd. 
     
     
       3.  A handle bag comprising a front and rear bag wall and an open mouth top portion, said open mouth portion being characterized by having handles which are located on opposite ends of said open mouth portion, said handles being integral extensions of said front and rear bag wall, said bag being further characterized in that the upper portion of each of said handles is substantially wider than the lower portion of said bag handles, said lower portions being located adjacent opposite ends of said bag mouth; said bag mouth being further characterized by having arcuate areas positioned at opposite ends of said mouth and adjacent the lower portions of said handles, said handles extending upwardly and inwardly from said arcuate areas, and the upper edges of said mouth extending above said arcuate areas and being located closer to the lower portion of said handles than to said upper portion of said handles. .Iaddend. .Iadd.4. In a bag structure comprising front and rear bag walls joined together to form a bag bottom, an open mouth top portion opposite to said bottom, said top portion characterized by having handles which are integral extensions of said front and rear walls, said handles having lower portions located at opposite ends of said open mouth and having upper portions located farther away from said bottom than is said open mouth; the improvement which comprises, said bag mouth being further characterized by having arcuate areas positioned at opposite ends of said mouth and adjacent the lower portions of said handles, said handles extending upwardly from one end of said arcuate areas, said bag mouth extending above said arcuate areas and having upper edges which are located closer to said lower portions of the handles than to said upper portions of said handles. .Iaddend.
