Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
149 words
A burst pack containing a quantity of material to be dispensed, and said burst pack being discardable after the material therein is dispensed and discharged, said burst pack embodying a container provided with a permanent seal at one end only, a molecular ultrasonic bond at the opposite end of the container from the permanent seal, said molecular bond providing a temporary seal, said molecular bond being weaker than the material of the container and being weaker than the permanent seal, said molecular bond at the end of the container being ruptured when a predetermined pressure is applied to the length of the molecular bond so that the material within the container will be discharged out through the ruptured end only after the bond has been ruptured and whereby when the container is squeezed the molecular bond will rupture to open the end of the container, the seals being liquidtight.
Claim 2
Dependent Claim
149 words
A burst pack containing a quantity of material to be dispensed, and said burst pack being discardable after the material therein is dispensed and discharged, said burst pack embodying a container provided with a permanent seal at one end only, a molecular ultrasonic bond at the opposite end of the container from the permanent seal, said molecular bond providing a temporary seal, said molecular bond being weaker than the material of the container and being weaker than the permanent seal, said molecular bond at the end of the container being ruptured when a predetermined pressure is applied to the length of the molecular bond so that the material within the container will be discharged out through the ruptured end only after the bond has been ruptured and whereby when the container is squeezed the molecular bond will rupture to open the end of the container, the seals being liquidtight.
Claim 3
Dependent Claim
28 words
The structure as defined in claim 1, wherein the molecular bond includes a permanent portion as well as a ruptureable partial portion that is adapted to be broken.
Claim 4
Dependent Claim
16 words
The structure as defined in claim 1, wherein the material in the container is a liquid.
Claim 5
Dependent Claim
32 words
The structure as defined in claim 1, wherein the molecular bond is positioned substantially normal to the longitudinal axis of the container and substantially at a right angle to the permanent seal.
Claim 6
Dependent Claim
23 words
The structure as defined in claim 1, wherein the molecular bond is disposed angularly with respect to the longitudinal axis of the container.
