Abstract

Abstract There is disclosed a multi-compartment package in the form of a tube having a breakable seal intermediate the ends thereof to provide at least two compartments therein, finger pulls secured to the opposed side walls of the tube in alignment with the breakable seal for pulling the side walls apart thereby breaking the seal, the package having a first greater dimension along the longitudinal axis of the breakable seal when the seal is unbroken and having a second smaller dimension in the direction of the longitudinal axis of the breakable seal after the finger pulls have been pulled apart to break the seal.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 251 words
A multi-compartment package comprising an elongated tube of flexible material including a heat-sealable synthetic organic plastic resin on at least certain portions of the inner surface thereof, said tube having the opposed walls thereof intermediate the ends thereof dispsosed adjacent to one another with the resin coating thereon heat-sealed to provide a breakable fluid-tight seal between the ends of said tube, said breakable seal being elongated in a direction transverse to the longitudinal axis of said tube, the ends of said tube having the opposed side walls thereof disposed adjacent to one another with the resin coating thereon heat-sealed to provide fluid-tight compartments disposed between said breakable seal and the sealed ends of said tube, and two finger pulls each consisting of a length of flexible material folded back upon itself with attachment flanges extending outwardly away from each other, said finger pulls respectively being secured to the opposed side walls adjacent to said breakable seal for grasping by a user to pull the same away from each other thereby breaking said breakable seal to interconnect the two compartments in said package, said package having a first greater dimension along the longitudinal axis of said breakable seal when said breakable seal is unbroken to provide a first wider configuration for said package and having a second smaller dimension in the direction of the longitudinal axis of said breakable seal after said finger pulls have been pulled apart to break said breakable seal to provide a second narrower configuration for said package.
Claim 2
Dependent Claim 251 words
A multi-compartment package comprising an elongated tube of flexible material including a heat-sealable synthetic organic plastic resin on at least certain portions of the inner surface thereof, said tube having the opposed walls thereof intermediate the ends thereof dispsosed adjacent to one another with the resin coating thereon heat-sealed to provide a breakable fluid-tight seal between the ends of said tube, said breakable seal being elongated in a direction transverse to the longitudinal axis of said tube, the ends of said tube having the opposed side walls thereof disposed adjacent to one another with the resin coating thereon heat-sealed to provide fluid-tight compartments disposed between said breakable seal and the sealed ends of said tube, and two finger pulls each consisting of a length of flexible material folded back upon itself with attachment flanges extending outwardly away from each other, said finger pulls respectively being secured to the opposed side walls adjacent to said breakable seal for grasping by a user to pull the same away from each other thereby breaking said breakable seal to interconnect the two compartments in said package, said package having a first greater dimension along the longitudinal axis of said breakable seal when said breakable seal is unbroken to provide a first wider configuration for said package and having a second smaller dimension in the direction of the longitudinal axis of said breakable seal after said finger pulls have been pulled apart to break said breakable seal to provide a second narrower configuration for said package.
Claim 3
Dependent Claim 17 words
The multi-compartment package set forth in claim 1, wherein said flexible material is an aluminum metal foil.
Claim 4
Dependent Claim 15 words
The multi-compartment package set forth in claim 1, wherein said resin is a polypropylene resin.
Claim 5
Dependent Claim 43 words
The multi-compartment package set forth in claim 1, wherein said sealed ends are elongated in a direction transverse to the longitudinal axis of said tube and lying in a common plane that is disposed normal to the longitudinal axis of said breakable seal.
