GOLLAPSIBLE TUBE.

Specification of Letters Patent. 7

Patented Mar. 26, 1912.

Application filed March 30, 1910. Serial No. 552,465.

To all whom it may concern:

Be it known that I, HERBERT W. SNOW a citizen of the United States, residing at Somerville, in the county of Middlesex and State of Massachusetts, have invented a new and useful improvement in a collapsible tube having telescoped on its cup-shaped end a detachable cap which encircles and is firmly fastened to the handle of a small brush. This tube is intended to be used for holding and distributing by the aid of said separable brush adhesives, gummy liquids, paints, oils, or any other soft substances which may be inclosed with,- in the tube, a full description of which invention I give in the following specification and drawings.

This invention relates to a collapsible tube having a large cup receptacle at one end to be used as a supplementary reservoir, the interior of which is connected to the tube by means of a small hole. The receptacle or reservoir mentionedis intended to hold part of the contents of the tube as it is pressed out through the hole from the tube and on to the brush which is inclosed within the reservoir bymeans of a cap which is fastened to the handle of the brush, or cast, stamped, or turned with the handle in one or two pieces, and which, when covering the open end of the reservoir by sliding or telescoping over the outer edge of the same, excludes the air from the inside sufficiently to keep the brush soft and the contents of the reservoir to about the same consistency as that contained within the tube itself and ready for immediate use. By simply pulling off the cap, the brush with the handle and cap attached becomes entirely separate from the tube and acts as a distributer; it being a convenient article to use and easily replaced on the reservoir end of tube again with the brush directly in the soft substance inclosed within the supplementary reservoir. 45

In the accompanying drawings,-Figure 1 is an elevation of my tube which in this view is shown as an empty tube with cap closing the supplementary reservoir at the end of the tube. Fig. 2 is a central, vertical section of Fig. 1. Fig. 3 is a horizontal section looking down on the tube I and on the brush cap IV and handle of brush V which is resting on the reservoir end of the tube. Fig. 4 is a horizontal section looking upward at tube I at the bottom of the tube and into it, showing the opening III into the pastes,

reservoir at the other end of the tube. Fig. 5 shows the tube with the bottom turned up or closed as it would appear when filled with any substance. Fig. 6 represents the brush with handle and cap after being raised off of the end of the reservoir end of the tube. Fig. 7 represents the brush, with the cap as it might be made with slanting or projected sides.

I Most collapsible tubes made have a direct passage from the outside atmosphere to the substance inclosed within the tube, thus causing the said substance to harden within .the tube and around the opening of same.

In my invention it will be found that, because of the large amount of the substance that can be kept in immediate or close proximity to the brush all the time, there is no difliculty in keeping the brush soft with the 'said substance so long as the cap of the brush is put securely on to the reservoir of the tube when not in use. And it will also be found that this reservoir end of the tube is of sufficient size to allow of the stirring of said substance which has been pressed therein from the main tube, thereby gaining a more uniform mixture than would be found on a brush which has been withdrawn directly from a large body of any substance whatsoever.

The tube specified I make of one piece of metal, though it might be made of two pieces screwed or fastened together at the junction where the main tube and the reservoir end meet, aluminum being preferred, although tin, or lead, or other metal may be used for it. The cap and handle of the brush is made of any of the above-mentioned metals, aluminum being preferred for this also. The so-called bristles, or other brush material, is fastened into the lower part of the metal handle securely.

In the drawings, the reference numeral I designates the main tube,.II the reservoir end of the tube, III the entrance from the main tube to the supplementary reservoir end of the tube, IV is the cap of the reservoir on the brush handle, showing the vertical sides of the same which may be slanting or projected at the bottom edge, sometimes. It will readily be understood that by making the sides of the cap flare out somewhat, I do not depart from the general arrangement, but simply procure for the top of the supplementary reservoir end a loose fitting cap, when needed, and it will be apparent thatsponge may be used instead of bristles for the brush.

Having thus described my invention, what I claim as new is as follows:

1. A collapsible tube which has a projection or supplementary reservoir at one end shaped like a cup, and an opening extending from the collapsible section to said reservoir for the purpose of keeping the reservoir supplied by pressure on the collapsible section with part of said sections contents in such proportions as to thoroughly surround the brush with the liquefied mass; a movable cap to cover the end of the reservoir having a handle and brush attached, said cap to slide on easily over the smooth edge of the reservoir, thus allowing said brush to be placed into the reservoir easily and quickly wholly immersed in the reservoirs contents at all times when not being used, the reservoir being large enough to allow any substance within to be stirred up with the brush it necessary before using it.

2. An apparatus of the character specified, comprising a collapsible tube, a neck formed on one end of said tube, provided with an opening communicating with the tube, a cup attached to said neck provided with a brush which projects into said cup as far as the opening to the tube, and a cap attached to said brush for the purpose of closing the cup. V

In testimony whereof I have afliXed my signature, in presence of two witnesses.
