Abstract
Abstract A container for liquids formed of a pair of cooperating sheets of plastic material wherein one of the sheets is formed to provide a main liquid containing cavity and a cooperating conduit providing a path for the withdrawal of liquid from the main cavity. The other of the sheets is laminated to the formed sheet so as to hermetically seal the main cavity and the cooperating conduit. A fracturable opening at the outlet of the conduit is provided permitting the withdrawal of liquid therefrom. The formed sheet being formed such that the assembly may be supported, when not in use, to dispose the outlet of the conduit at a higher level than the main cavity to militate against the unintentional spillage of liquid.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
172 words
A liquid filled container assembly comprising: a formed sheet of plastic material having relatively flat portions defining an open main liquid containing cavity and a spaced apart adjacent elongate open conduit having one end communicating with the interior of the main cavity, the opposite outer end of the open conduit terminating in a drinking spout, the main cavity including a bottom wall having a relatively flat surface for supporting said container assembly in periods of non-use whereby the drinking spout terminates at a level above the highest point of the cavity; a sheet of relatively flat plastic material overlaying said formed sheet and being sealed to the flat portions thereof to hermetically seal the main cavity, the elongate conduit, and the spout; and weakening means proximate the spout of the conduit and spaced from the cavity for facilitating the tearing off of the portion of the sealed sheets defining the outer end of the conduit to expose the spout to allow liquid to be withdrawn from the main cavity and the conduit.
Claim 2
Dependent Claim
172 words
A liquid filled container assembly comprising: a formed sheet of plastic material having relatively flat portions defining an open main liquid containing cavity and a spaced apart adjacent elongate open conduit having one end communicating with the interior of the main cavity, the opposite outer end of the open conduit terminating in a drinking spout, the main cavity including a bottom wall having a relatively flat surface for supporting said container assembly in periods of non-use whereby the drinking spout terminates at a level above the highest point of the cavity; a sheet of relatively flat plastic material overlaying said formed sheet and being sealed to the flat portions thereof to hermetically seal the main cavity, the elongate conduit, and the spout; and weakening means proximate the spout of the conduit and spaced from the cavity for facilitating the tearing off of the portion of the sealed sheets defining the outer end of the conduit to expose the spout to allow liquid to be withdrawn from the main cavity and the conduit.
Claim 3
Dependent Claim
63 words
The invention defined in claim 1 wherein the main liquid containing cavity of said formed sheet is defined by a pair of spaced apart side walls, spaced apart end walls, and said bottom wall, said side walls and said end walls extending approximately perpendicularly from the bottom wall, and one of said end walls extending a greater distance than the opposing end wall.
Claim 4
Dependent Claim
32 words
The invention defined in claim 2 wherein the opposite outer end of said conduit terminating in a drinking spout extends outwardly of the main cavity adjacent said one of said end walls.
Claim 5
Dependent Claim
17 words
The invention defined in claim 2 wherein said drinking spout is covered by a protective outer wrap.
