Abstract
A collapsible tube winder and lock device wherein the winder includes a slotted key member for receiving the crimped closed end of a collapsible tube, the contents of the tube being dispensed by turning the key to wind the tube around the key to thereby squeeze the contents from the tube. The lock device includes an arm having depending legs detachably connected to the winder. The arm engages a wound portion of the collapsible tube to prevent the tube from unwinding itself from the winder.
Claims5
In combination, a winder and a lock device for a collapsible tube, said tube having a closed, crimped end and a discharge end, said winder comprising, a key member having a shank portion, a longitudinally extending slot extending through said shank portion for receiving the crimped, closed end of the collapsible tube, at least one head integral with an end of said shank portion to facilitate the manual winding of the collapsible tube on said shank portion to squeeze the contents of the tube through said discharge end, and an opening extending through each end of said shank portion and spaced outwardly from each end of said slot, each opening being aligned and coplanar with said slot;
- said lock device comprising, an arm spaced above said shank portion and extending parallel thereto, a resilient leg member integral with each end portion of the arm and depending therefrom, and teeth on said depending leg members biased into engagement with a side wall in each opening for releasably connecting the lock device to the winder, whereby after the tube has been wound on the shank portion, the lock device is connected to the winder by inserting the depending legs into the openings, to thereby hold the arm against a wall portion of the wound tube to prevent the tube from unwinding itself from the shank portion.
In combination, a winder and a lock device for a collapsible tube, said tube having a closed, crimped end and a discharge end, said winder comprising, a key member having a shank portion, a longitudinally extending slot extending through said shank portion for receiving the crimped, closed end of the collapsible tube, at least one head integral with an end of said shank portion to facilitate the manual winding of the collapsible tube on said shank portion to squeeze the contents of the tube through said discharge end, and an opening extending through each end of said shank portion and spaced outwardly from each end of said slot;
- said lock device comprising, an arm spaced above said shank portion and extending parallel thereto, a leg member integral with each end portion of the arm and depending therefrom, and a circular foot integral with the lower end of each depending leg cooperating with said openings for releasably connecting the lock device to the winder, each opening having an arcuate portion communicating with a slot extending transversely to the shank portion, the arcuate portion of the opening and associated slot portion being dimensioned to allow the leg and associated foot to be inserted through said opening, the portion of the transverse slot on each side of the arcuate portion having a lateral dimension less than the diameter of the circular foot for holding the locking device on the winder, whereby after the tube has been wound on the shank portion, the lock device is connected to the winder by inserting the depending legs into the openings, to thereby hold the arm against a wall portion of the wound tube to prevent the tube from unwinding itself from the shank portion.
