Application filed April 80, 1920. Serial No. 377,975.

7 To all whom it may concern Be it known that we, LUKE J. FAIRBANKS and JOHN R. KELLY, both citizens of the I United States, residing atLos An les, in

the countyof Los Angeles and tate of California, have jointly invented new and useful Improvements in Sample-Dispensers, ofwhich the following is a. specification.

This invention relates to'sample dispensers, and has for its object to provide a sample dispenser suitable for use of grocery salesmen, canvassers and the like, for display and dispensing of wares such as semiliquids, pick es, the contents of canned goods, and in fact, all goods of such nature as would otherwise be diflicult of display a and sampling. v I

A further object of the invention is to provide an improved sealing means associated with the closure and'cooperating with aertain portions of the receptacle whereby such closure may be readily and quickly placed in position and removed and. when assembled will render the receptacle fluidhl 1 i he invention has for a further object to provide an improved dispenser of the general character stated in which utility is comand services, which may be readily carried in apocket, and which will be 'super1or 111 point of relative simplicity arid mexpensiveness of construction and organizatlon, combined with efi'ectiveness in operation, and use, and durability, andv compactness in form.

With the above and other objects in view, the invention consists in the novel provision, formation, association and relative arrangement and interrelation of parts, members and features, all as hereinafter described shown in the drawing and finally pointed out in claims.

In the drawing:

Figure 1 is'an isometric view of the improved dispenser showing the parts in assembled position;

Fi 2 is a cross sectional side elevation, certam parts being broken away, of thedis- P615881, and taken on the line w w Fig. 3; an

Fig. 3 is a vertical end view, certain parts being broken away, of the dispenser, and

taken on the line as -m Fig. 2.

ing, A designates a. container, B a closure means for said container, C a sealing means,

and D means for securing the closure means.

B to the container A.

. The container A comprises a bottom member 1, sides and 3 and ends 4 and 5; said contalner being open at the top; the side and

end portions

2, 3, 4 and 5, respectively have adjacent their upper edges a downwardly and outwardly curved rim 6.

The closure means B comprises a plate having practlcally a flat top surface 7, with certain portions such as 8 curving down-, wardly completely around the plate. The plate is likewise provided with an upwardly extending flange 9 which in turn is provided 5 with a rim which extends first laterally as at 10 and then 1s downwardly and returnedly curved as at The closure-means B like- -w1se 1s provlded with a central annular convex or outside or upstruck beaded portion 12 and a central orifice or perforation 13 is'located intermediate the annular convex beaded portion.

The sealing means C prefera-bl includes an endless rubber gasket or ban made so that it resembles in cross section, as shown in Figs. 2 and 3, a wedge having angularl disposed faces as 14, 15 and 16, one of whic faces, as 15, engages a surface of the flange 9 while another of its faces, as 16, engages the laterally extending portion 10 of the rim, while the downwardly and returnedly curved portion 11, of the rim, engages a small portion of the face 14. Thus the wedge-shaped sealing gasketv or band C is held in close relation to the rim part and the flange part of the closure means B, as illus-' trated in the fi res.

The means for securing the closure member B to the container A comprises a cross bar 17 having downwardly and u wardly bent end portions as shown at 1 a and 17 The upwardly bent portions as 18 and 19 en age the surface of the down.- wardly 31K? outwardly curved rim 6 of the container A. There is an enlar ed part 20 central of the cross bar 17 and which enlarged part is provided with a threaded perforation 21, extending therethrough. A threaded bolt 22 passes through and turns upon the threaded portion of the perforation 21.- One end of said bolt is provided inner peripheral surface adjacent the rim with an 'ann'ularflanged cap as at 23, having an enveloping gasket 23 thereon, while the opposite end is provided with an integrally formed head 24. v I

The operation is as follows: When the closure means B is in position upon the container -A as shown in the figures, the cross bar 17 is placed in position so thatits downwardly and upwardly bent portions vcontact with the undersurface of the rim of the container and the annular flange cap 23 will rest between the central annular convex beaded portion of the closure means B.

As Wlll be observed by referrin to Figs. 2 and 3, the angularly disposed ace 14 of the sealing means C will bear'against the 6 of the container A. If now the bolt head 24 is revolved in such a manner that it tends to move downwardly, adownward pressure will be exerted a ainst the closure means B while an upwar pressure will be exerted on the container A.

Because the sealing means is provided with angularly disposed faces, when the closure B isin position upon the container A. as illustrated in the figures, it will be observed that any contents, especially if they be fluids, that may be contained within the container A, will, in case of shaking, only contact with the interior surface of the side walls and end-walls of the container, and

the inner surface of the closure means B as far as the flanged portion of said closure means. The angularly disposed face 14 of the sealing means prevents any liquid from splashing or coming in contact with the outer peripheral surface of the rim 6, and it is a main feature of this invention that the face 14 of the sealing means 0 should be so disposed that a pressure exerted upon the closure means B will only increase the wedge-like gripping action exerted between the sealing means and the inner surface ofthe container adjacent the rim. It is com-' monly known that if a fluid is permitted to moisten the rim beneath a rubber gasket and the closure is then sealed over said means that the fluid contents within the container may leak because of said moisture between the sealing means and the rim, but with the articular construction above described this eaking is of course obviated.

Sometimes it is diflicult to remove a closure after it has once been sealed upon its corresponding container member, but in this invention after releasing the cross bar 17 the perforation or orifice contained within the closure means D will allow theatmospheric pressure upon the interior of the container A to equalize with the atmospheric pressure on the exterior of the container, permitting the cover to be removed. providing the rubber gasket or sealing means "C is not stuck to the container A. If this should happen, particularly if the cover were sealed upon the container when the same'ls warm, the sealing means C would tend to bind or stick very closely to the rim edge 6. In order to release the cover, the

. securing means D is provided with an extension 17 which is integrally formed with the part-17. i This extension 17, allows the cover B to be pried from the container A,

and the means D twisted.

It is obvious that many changesand modifications may be made in practising the above inventionas shown in the drawings, described in the specification and pointed outin claims, but in no case departing from the true spirit thereof Having thus disclosed our invention, we claim and, desire to secure by Letters Patent:
