E. S. GRIGSBY TUBE EVACUATOR Filed Aug. 15, 1928 f INDVENTOR 15 12 ES. Grg'sby BY Q .DJAAIL ATTORNEY Patented June eao S. GBIGSBY, F LODI, cumonnn 'ruBn nvncuaron Application filed. August 13, 1928. Serial Ho. 299,284.

This invention relates to devices for dispensing the contents of flexible tubes, especially those in which tooth paste, shaving cream, and similar plastic materials are marketed. The principal object provide manently mounted as long as it retams any of its contents, and means mounted in connection with the casing for enabling a squeezingpre ssure to be easily exerted against the tube at any point ofits length and for the full width thereof so that the contents .will be evacuated from the mouth of the tube. By

means of this device thetube is always ina certain definite location when wanted and the contents may be dispensed without the manual and uncertain squeezing of the tube as is now commonly done.

A further ob'ect of the invention is to provi'de a device '0 this character so constructed as to work equally well with tubes of different diameters and lengths within, of course, certain limitations.

of my invention is to duce a simple and inexpensive device and yet one which will be exceedingly effective for the purpose for which it is designed.

These objects I accomplish by'means of such structure and relative arrangement of parts as willfully appear by a perusal of the Fig. 3 is a cross section of the device showin a full tube in place. I

a casing in WlllCh the tube is per- V the bottom of the same. A further object of the invention is to pro- Referring now more particularly to the r characters of reference on the drawings, the

numeral 1 denotes a rectangularcasing which 7 V is open on the front and provided with 'top and bottom ears 2 at-the back for the reception of screws to hold the casing against a wall or other supporting surface in a vertical position;

' The dimensions of the casing are-such as to enable it to receive an tube 3 within the I range of the-usual stan ard sizes in which the particular products previously mentioned are put out. The bottom of the casing is provided with a centrally disposed opening 4 to receive the neck or mouth 5 ofthe tube therethrough. Above the tube the sides of the casing are provided with horizontal slots. 6 in which a pin 7 is slidable and turnable. Fas-I tened on this pin and depending therefrom is a strip 8 of spring steel havingconsiderable o5 flexibllity longitudinally but rigid transversely. The strip is at'least as wide as the tube and depends lengthwise of the casing to about Hinged on top of the casing is a lid 9 extending means 10 between the casing and the side v flanges of thelid at the lower end thereof.

This lid has a longitudinal slot 11 of lesser width than the strip 8 but of siiiiicient width to readily accommodate a finger of the operator. When the tube is in place and-t e lid is closed thereon, the side edges of the stri will be concealed, the tube will be invisib e and the device will present an extremely neat and attractive appearance. v

In operation it is only necessa for the operator to press the strip 8 inwar l which will exert a pressure a inst the tube for the full width thereof an cause the contents to be discharged from. the mouth projecting below the casing. The stri being rigid transversely and as wide as t e tube insures that the latter will be 'flattened simultaneously over its entire width so that no pockets'are I.

own the open 70 front of the casing, there being friction catch evacuated. If, then, the strip is manipulated so as to first flatten the tube at its upper end "and the finger pressure is' exerted so as to gradually cause such ressure to work down the entire length of t e tube, it will be seen that the entire contents of the tube will be evacuated without any waste. 7

Owing to the use of the slot and pin arrangement to which the spring strip is attached, the latter is permanently mounted in place while it canbe easily raised to enable a tube to be inserted or removed, and may also be pressed freely toward the back of the casing as the adjacent end of the tube becomes flattened without bending or straining the strip atits fastened end. The use of the slotted lid besides giving the device a neat appearance prevents the lower end of the strip from moving outwardly of the casing when pressure is exerted on the strip above.

such end, as indicated in Fig. 4.

If desired or found necessary, a slidable cap or cover 12 supported by guides 13 .mounted on the bottom of the casing, may

, be provided to normally close the open mouth of the tube. A depending finger piece 14 enables this. cover to be readily moved to or from its mouthelosing' osition.

From the foregoing escription it will be readily seen that I have lproduced such a .de-

vice as substantially s the objects of the invention as set forth herein. I

While this specification sets forth in detail the present and preferred construction of the (knee, still in practice such deviations from such detail may be resorted to as do not form a depa from the spirit of the invention, as defined by the appended claims.

- Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent is: '1 A tube evacuator including anopenfront casing to support a tube, a flexible presser strip disposed in the casingin front of the v tube, atransverse pin on oneend of the strip,

the sides of the casin adj adent one end having horizontal slots mto which the ends of the pin project.

2. A tube evacuator including an openfront casing to supporta tube, and having an in one end for the projection of the o neck of the tube, a flexible strip disposed in front of the tube, and connection means between the strip and casing at the end thereof opposite to the neck-opemng; the free end of the strip being vertically spaced from the corresponding end of the casing a suflicient distance to enable said, end being pressed inwardly just beyond the portion of the tube adjacent the neck. Y
