Abstract
A refuse bag joined at three straight sides and an open fourth side which includes projecting tie parts that can be readily tied by hand. The tie parts are each rounded peaks separated by convex valleys. Each peak has side portions and a top which has a convex part including convex transitional portions connected to the side portions which otherwise connect to the valleys. Preferably, the peaks and valleys form a sinusoid.
Claims14
A refuse bag used for storing and/or for transporting material such as garbage or refuse prior to collection or transport to disposal, comprising:
- front and rear panels joined to each other along three straight sides and being open on the fourth side, and
- projection means including projecting spaced tie parts in the fourth side of each of said front and rear panels for closing said fourth open side by readily tying said tie parts together by hand,
- said tie parts being respective rounded peaks separated by concave valleys, each peak having side portions and a top having a convex part which includes convex transitional portions respectively connected to said side portions at one end of said side portions, an opposite end of said side portions being connected to a respective said valley.
A refuse bag used for storing and/or for transporting matter such as garbage or refuse prior to collection or transport to disposal, comprising:
- front and rear panels joined directly to each other along a pair of opposite straight sides, being joined at a third straight side between said pair of sides and being open on the fourth side,
- projection means including projecting spaced tie parts in the fourth side of each of said front and rear panels for closing said fourth open side by readily tying said tie parts together by hand,
- said tie parts being respective rounded peaks separated by concave valleys, each peak having side portions and a top having a convex part which includes convex transitional portions respectively connected to said side portions at one end of said side portions, an opposite end of said side portions being connected to a respective said valley.
A roll of tubular plastics material from which is formed a plurality of refuse bags for storing and/or transporting matter such as garbage or refuse prior to collection or transport to disposal comprising:
- (a) front and rear panels of said plastics material;
- (b) straight end welds that weld the panels together at suitably spaced locations, transversely to the direction of the materials;
- (c) a straight cut adjacent to each weld, and
- (d) a separating cut forming an open end for two refuse bags between a pair of end welds, the said separating cut forming for each said bag on opposite sides of said separating cut projecting means including spaced projecting tie parts in the front and rear panels for closing said open end of a bag removed from the roll by readily tying said tie parts by hand,
- said tie parts being respective rounded peaks separated by concave valleys, each peak having side portions and a top having a convex part which includes convex transitional portions respectively connected to said side portions at one end of said side portions, an opposite end of said side portions being connected to a respective said valley.
