Abstract
Abstract A container comprises a molded tube having a cap portion attached at one of its ends by a break-away junction and a sealed closure at the other end of its ends. The closure is formed after filling the tube with a unit dose. A cord is attached at one end to the cap by a thickened portion used as an alignment guide when filling and at the other end to the closure, and the cap remains attached to the tube by the cord after breaking the break-away junction.

Claim 1
Independent Claim
167 words
A one-piece unit dose container-closure assembly made of a molded plastic material comprising an elongated tubular member having an open end to permit filling, a closure cap integrally connected to the opposite end of said tubular member, a break-away junction between the closure-cap portion and the tubular member, a cord integrally attached to the closure-cap portion and having a thickened portion extending outwardly from said cap in a predetermined orientation with respect to said open end to provide an alignment guide for insertion of said tube into a slotted filling mandrel, said cord extending downwardly from said cap to a point adjacent the lower terminal edge of said tubular member where it is permanently heat sealed at its free terminal end to the lower terminal edge of the tubular member when it is sealed by application of heat and pressure, whereby said cap portion remains attached to said tubular member by said cord upon separation of said closure-cap portion from said tubular member at said break-away junction.
