Abstract
Abstract A package comprising a cylindrical plastic tube closed at each end by an ultrasonic band seal. The seal at one end has a sealed region which is narrower than any portion of the other seal whereby squeezing of the package produces an immediate one-shot dispensing of liquid contained therein by causing rupture of the narrow region of the seal. Various package forms include perpendicularly arranged bands to provide a tetrahedral shape, a tab extending beyond one seal to provide identification of the contents of the package, notched seals providing a tear open package, and a multiple package construction in which one fluid containing tube is contained within another.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
124 words
A package comprising a cylindrical tube of flexible material, a first end of said tube being closed by a first ultrasonic seal extending transversely across the tube, a second end of said tube being closed by a second ultrasonic seal extending transversely across the tube and having a portion narrower than any portion of the first seal for rupturing under pressure, said tube providing an internal chamber between said seals for containing a product, a tab extending beyond said first seal comprising a flattened extension of said tube, and a plurality of coded markings on said tab to provide identification of the contents of the package comprising ultrasonic welds in the form of coded markings for securing together overlapped portions of said tube extension.
Claim 2
Dependent Claim

A package comprising a cylindrical tube of flexible material, a first end of said tube being closed by a first ultrasonic seal extending transversely across the tube, a second end of said tube being closed by a second ultrasonic seal extending transversely across the tube and having a portion narrower than any portion of the first seal for rupturing under pressure, said tube providing an internal chamber between said seals for containing a product, a tab extending beyond said first seal comprising a flattened extension of said tube, and a plurality of coded markings on said tab to provide identification of the contents of the package comprising ultrasonic welds in the form of coded markings for securing together overlapped portions of said tube extension.
Claim 3
Dependent Claim
19 words
A package according to claim 1 wherein said welds are arranged in accordance with the Braille system of letters.
Claim 4
Dependent Claim
20 words
A package according to claim 1 including a band seal extending across the extended end of said flattened tube extension.
Claim 5
Dependent Claim
101 words
A package comprising a cylindrical tube of flexible material, a first end of said tube being closed by a first ultrasonic seal extending transversely across the tube, a second end of said tube being closed by a second ultrasonic seal extending transversely across the tube, said tube providing an internal chamber between said seals for containing a product, and one of said end seals comprising four overlapped wall portions having a length approximately one quarter of the circumference of said tube and formed by folding a closed end of the tube about a longitudinally extending fold line on the tube circumference.
Claim 6
Dependent Claim
101 words
A package comprising a cylindrical tube of flexible material, a first end of said tube being closed by a first ultrasonic seal extending transversely across the tube, a second end of said tube being closed by a second ultrasonic seal extending transversely across the tube, said tube providing an internal chamber between said seals for containing a product, and one of said end seals comprising four overlapped wall portions having a length approximately one quarter of the circumference of said tube and formed by folding a closed end of the tube about a longitudinally extending fold line on the tube circumference.
