HENRY IKIELBERG, OF MARTIN'S FERRY, OH IO.

COILING KEY FOR COLLAPSIBLE TUBES.

Application filed October 3, 1927. Serial No. 228,601.

This invention relates to a device for coil ing collapsible tubes to effect removal of the contents of such tubes, and it has for its primary object to provide a simple and inexpensive device or instrument adapted for application to an end of a collapsible tube of the character commonly employed as containers for pastes, paints and the like, whereby such tube may conveniently be rolled for ejecting the contents through the open end of the latter.

A further object is to provide an instrument of the character mentioned by means of which is obviated the necessity for the application to the collapsible tube body of finger pressure, which latter tends unduly to distort the tube and which, ordinarily, is ineffectual for completely removing the contents of the latter.

In describing the invention in detail, reference is herein had to the accompanying drawings, in which- Figure 1 is a front elevation of the invention;

Figure 2 is a side elevation of the same;

Figure 3 is an end elevation;

Figure 4 is a front elevation of a slightly modified form of the invention.

The invention consists of a key-like onepiece structure which includes a body 1, preferably of cylindrical form in cross section, and a transversely disposedfinger piece 2 located at oneend of said body. As shown in Figs. 1 to 4, inclusive, the device is constructed of sheet metal, the body 1 thereof being bent into approximately tubular form with the opposite, or approaching, edges spaced apart to form a longitudinally extendingslot 3. Said slot is designed to receive therein the closed bottom end of acollapsible metal tube 4, shown in broken lines in Fi s. 1, 2 and 3, following which said tubular ody is rotated to coil thereon the metal of such tube, thereby to exert pressure for expelling the tube contents from its open end, as desired.

The side of the tubular body 1 opposite theslot 3 is extended at one end to form thefinger piece 2 which consists of two oppositely disposedwings 2, each of which is made of concavo-convex form designed 'conformably to fit the ball of a thumb or finger, thereby to facilitate the grasping of the finger piece by the user. As shown, thewings 2 are reversely disposed.

It is preferred that one of the approaching, or slot-defining edges of the tubular body 1 shall present one or more tooth-like proj ections 5 located in the circumferential plane of said body, and that the confronting edge shall be correspondingly recessed, as shown at 6, thereby to render-theslot 3 slightly sinuous throughout a portion of its length. Said projections orteeth 5 are designed, upon rotation of the instrument relative to the col lapsible tube, to seat in depressions thereby formed in the metal of the tube for securing the instrument against chance displacement from its operative position. As is apparent, since the metal of the tube is readily flexible, introduction of the flattened closed end of said tube in thesinuous slot 3 may be readily effected.

The structure. shown in Fig. 4 differs from that disclosed in Fig. 1 only in that a plurality ofteeth 5 are substituted for the single tooth of the lastmentioned figure.

As is obvious, the instrument is permanently carried by the tube following application to the latter, and, in the continued use thereof, the entire body portion of the tube is coiled upon the body, thus effecting removal of substantially the entire contents.

What is claimed is- 1. A key-like device of the character de scribed comprising a tubular sheet metal body havin at one end thereof a finger-piece where y said body may be rotated, the confronting edges of said body being correspondingly serrated and spaced a art to form a sinuous longitudinally exten ingslot adapted for the reception of the flattened end 0 collapsible tube.

2. A key-like device of the character described comprising a tubular sheet metal body havin at one end thereof a finger-piece where y said body may be rotated, one of the confronting edges of said body carrying intermediate its ends a tooth-llke rojection and the opposite edge being provi ed with a correspondingly located recess, said edges being spaced apart to form a slot adapted for the reception of the flattened end of a collapsible tube.

In testimony whereof, I aflix my signature.
