Abstract
Abstract A tube container comprises a tubular member having one end thereof flanged inwardly to form an internal flange facing the opposite end of said tubular member and a discharge member, provided with a thin annular flange diverging in the discharge direction of the tube container, such that its maximum dimension exceeds the inner dimension of the tubular member. The discharge member is inserted in the tubular member such that the annular flange thereof is located in the space between the outer wall of the tubular member and the internal flange thereof.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
180 words
A container comprising a tubular member having a first end and a second end, the first end of said tubular member folded inwardly to form a first annular flange at said first end directed toward said second end and defining a first annular space between said first annular flange and said tubular member, a discharge member attached to said tubular member at said first end and being designed to dispense the contents of the container, said discharge member having a peripheral portion with a resilient second annular flange formed thereon having an outer lip portion of unflexed maximum diameter greater than the inner diameter of said tubular member directed toward said first end of said tubular member and defining a second annular space between said resilient annular flange and said discharge member, said resilient annular flange of said discharge member being in resilient contact with the inner surface of said tubular member and with said lip portion sealingly retained in said first annular space, and said first annular flange of said tubular member being retained in said second annular space.
Claim 2
Dependent Claim
180 words
A container comprising a tubular member having a first end and a second end, the first end of said tubular member folded inwardly to form a first annular flange at said first end directed toward said second end and defining a first annular space between said first annular flange and said tubular member, a discharge member attached to said tubular member at said first end and being designed to dispense the contents of the container, said discharge member having a peripheral portion with a resilient second annular flange formed thereon having an outer lip portion of unflexed maximum diameter greater than the inner diameter of said tubular member directed toward said first end of said tubular member and defining a second annular space between said resilient annular flange and said discharge member, said resilient annular flange of said discharge member being in resilient contact with the inner surface of said tubular member and with said lip portion sealingly retained in said first annular space, and said first annular flange of said tubular member being retained in said second annular space.
Claim 3
Dependent Claim
45 words
A container as claimed in Claim 1 wherein the outer surface of said resilient second annular flange has a generally conical shape in that it diverges outwardly from the circumference of said discharge member in a direction toward said first end of said tubular member.
Claim 4
Dependent Claim
55 words
A container as claimed in claim 1 wherein the lengths of the two flanges along the longitudinal axis of the tubular member are approximately the same such that the flange of each of said members will be in contact with the other member within the respective annular space in which each such flange is retained.
Claim 5
Dependent Claim
66 words
A container as claimed in claim 3 wherein the peripheral portion of said discharge member is an annular wall, said second annular flange projecting from said annular wall and said second annular space being formed between said second annular flange and said annular wall, and the flange of each of said members being retained in the annular space of the other member by a friction fit.
Claim 6
Dependent Claim
30 words
A container as claimed in claim 4 wherein said tubular member has an annular zone of reduced thickness where the first end is folded to form said first annular flange.
Claim 7
Dependent Claim
46 words
A container as claimed in claim 4 wherein said second end of said tubular member is sealed, and said discharge member comprises self-closing closure means for opening in response to pressure applied to the contents of the container and for closing upon the release of pressure.
