Abstract
The closed end of a toothpaste tube is inserted into an internal cavity of a self-supporting toothpaste dispensing device, and a key is manually turned to coil the tube within the cavity. The cavity walls are resiliently yieldable and constantly bear against different contact zones on the coiled tube to empty its paste contents.
Claims12
A light-weight, self-supporting, portable dispensing device for manually emptying the paste contents from collapsible tubes, comprising:
- (a) stand means for supporting an elongated, paste-containing collapsible tube above a support surface, said stand means having resilient mouth-forming wall portions spaced apart of each other to resiliently bear against opposite sides of the tube and bounding longitudinally-extending mouth through which the tube passes lengthwise from its closed end towards its opposite dispensing end,
- said stand means also having resilient cavity-forming wall portions spaced apart of each other and extending away from the mouth-forming wall portions to bound a cavity which communicates with said mouth,
- said stand means further having resilient extension wall portions extending away from said cavity-forming wall portions;
- (b) manually-operated means located in said cavity for holding the closed end of the tube, and being turnable about a longitudinally-extending turning axis for successively drawing the tube lengthwise through said mouth and thereupon into said cavity, and for concomitatnly successively coiling the drawn-in tube portions about said turning axis to form a coiled tubular portion in said cavity;
- and
- (c) retainer means mounted on the stand means and extending below the manually-operated means and the coiled tubular portion for retaining both the former and the latter in said cavity,
- said retainer means and said cavity-forming wall portions being resiliently yieldable to permit said cavity to increase in volume to accommodate an increase in volume of the coiled tubular portion due to further coiling,
- said resiliently yieldable retainer means and said resilient cavity-forming wall portions all constantly resiliently bearing at different contact zones on the coiled tubular portion, said contact zones being spaced apart of each other circumferentially about said turning axis and sequentially, as considered in lengthwise direction of the tube, for successively emptying the paste contents from the coiled tubular portion,
- said retainer means being mounted on said extension wall portions for sliding movement relative thereto.

A lightweight, self-supporting, portable dispensing device for manually emptying the paste contents from collapsible tubes, particularly toothpaste tubes, comprising:
- (a) stand means for supporting an elongated, paste-containing, collapsible tube above a support surface, said stand means including a base portion for engaging the support surface, and a pair of side walls located at opposite sides of the base portion and extending upwardly therefrom, said stand means having
- resilient mouth-forming wall portions located on said side walls of the stand means and being spaced apart of each other to constantly resiliently bear against opposite sides of the tube, said mouth-forming wall portions bounding a longitudinally-extending mouth through which the tube passes lengthwise from its closed end towards its opposite dispensing end, and
- resilient cavity-forming wall portions spaced apart of each other and extending away from the mouth-forming wall portions to bound a cavity which communicates with said mouth, said cavity-forming wall portions including resilient extension wall portions extending away from said cavity-forming wall portions and bounding opposite sides of said cavity;
- (b) manually-operated means located in said cavity for holding the closed end of the tube, and being turnable about a longitudinally-extending turning axis for successively drawing the tube lengthwise through said mouth and thereupon into said cavity, and for concomitantly successively coiling the drawn-in tube portions about said turning axis to form a coiled tubular portion in said cavity;
- and
- (c) retainer means mounted on said extension wall portions for sliding movement relative thereto, said retainer means including a base section extending between the extension wall portions, a pair of side sections located at opposite sides of the base section and extending away from the same, and a central support section intermediate the pair of side sections and extending away from the base section for retaining the manually-operated means and the coiled tubular portion in said cavity, said retainer means and said cavity-forming wall portions being resiliently yieldable to permit said cavity to increase in volume to accommodate an increase in volume of the coiled tubular portion due to further coiling,
- said resiliently yieldable retainer means and said resilient cavity-forming wall portions all constantly resiliently bearing at different contact zones on the coiled tubular portion, said contact zones being spaced apart of each other circumferentially about said turning axis and sequentially, as considered in lenthwise direction of the tube, for successively emptying the paste contents from the coiled tubular portion.
