Abstract
Abstract A dispensing apparatus for ejecting paste-form substances from a collapsible-tube container is provided having a pair of interfitting, elongated channels assembled to receive a collapsible tube and permit relative limited compressive movement of the two channels. One channel is provided with an end wall for cooperatively engaging an end of the collapsible tube and restraining the tube against longitudinal movement in one direction. A roller positioned within the assembled channels for revolving movement about an axis transverse to the longitudinal axis of the channels is operated on by one of the channels to compress the collapsible tube disposed between the roller and the other channel. This compression expells the contents of the collapsible tube container with the relative movement of the two channels being limited to that for ejecting a predetermined quantity of the contents.

Total Claims: 9
Claim 1
Independent Claim
207 words
A dispensing apparatus for collapsible tube containers comprising: A. an elongated base having a bottom wall and a pair of longitudinally extending, spaced apart side walls forming an open-topped channel to receive a container, and an end wall disposed in upstanding relationship to said bottom wall and extending transversely between said side walls for cooperatively engaging and supporting a container and restricting axial movement thereof to one direction relative to said base, B. an elongated, channel-form cover adapted to interfit with said base in assembled relationship and having a pair of longitudinally extending, spaced apart side wall flanges that are each disposed in parallel planar relationship to a respective side wall of said base and means interengaging said side walls and side wall flanges to permit limited relative transverse movement thereof, C. biasing means interposed between said base and cover to normally urge said base and cover to a relatively separated position, and D. an elongated roller positioned between said assembled base and cover for free movement longitudinally and transversely thereof, said roller having a surface engageable with said cover to compress a container positioned in the apparatus by relative compression of said base and cover in opposition to said biasing means thereby dispensing the contents thereof.

A dispensing apparatus for collapsible tube containers comprising: A. an elongated base having a bottom wall and a pair of longitudinally extending, spaced apart side walls forming an open-topped channel to receive a container, and an end wall disposed in upstanding relationship to said bottom wall and extending transversely between said side walls for cooperatively engaging and supporting a container and restricting axial movement thereof to one direction relative to said base, B. an elongated, channel-form cover adapted to interfit with said base in assembled relationship and having a pair of longitudinally extending, spaced apart side wall flanges that are each disposed in parallel planar relationship to a respective side wall of said base and means interengaging said side walls and side wall flanges to permit limited relative transverse movement thereof, C. biasing means interposed between said base and cover to normally urge said base and cover to a relatively separated position, and D. an elongated roller positioned between said assembled base and cover for free movement longitudinally and transversely thereof, said roller having a surface engageable with said cover to compress a container positioned in the apparatus by relative compression of said base and cover in opposition to said biasing means thereby dispensing the contents thereof.
Claim 3
Dependent Claim
23 words
A dispensing apparatus according to claim 1 wherein said roller is formed with an outer surface having a relatively high co-efficient of friction.
Claim 4
Dependent Claim
39 words
A dispensing apparatus according to claim 1 wherein said cover includes a web interconnecting between said side wall flanges and having an inwardly facing surface engaging said roller, said inwardly facing surface having a relatively high co-efficient of friction.
Claim 5
Dependent Claim
31 words
A dispensing apparatus according to claim 1 wherein said means interengaging said side walls and side wall flanges includes cooperatively engageable pins and slots formed with the respective base and cover.
Claim 6
Dependent Claim
74 words
A dispensing apparatus according to claim 4 wherein said pins are formed on said base side walls and project lateraLly therefrom and said slots formed in said cover side wall flanges include an inner portion of predetermined length extending transversely to the longitudinal axis of the apparatus through which a respective one of said pins may be displaced, said slots each having closed ends to limit relative transverse movement of said cover and base.
Claim 7
Dependent Claim
45 words
A dispensing apparatus according to claim 5 wherein said slots each include an outer portion opening at the outer longitudinal edge of the respective side wall flange and communicating with the respective inner portion at the side thereof most closely adjacent said base end wall.
Claim 8
Dependent Claim
39 words
A dispensing apparatus according to claim 6 wherein said pins are formed on said base side walls and project laterally outward of said base and said cover side wall flanges extend along the outer surfaces of said base sidewalls.
Claim 9
Dependent Claim
27 words
A dispensing apparatus according to claim 7 wherein said slots are formed as grooves in the cover side wall flanges opening at the inwardly facing surfaces thereof.
