UNITED STATES DANIEL W. LAYMAN, OF INDIANAPOLIS, INDIANA.

DISPENSING TOP FOR CONTAINER-S.

Application filed April 19, 1924. Serial No. 707,601.

To all whom, it may concern:

Be it known that I, DANIEL W. LAYMAN, a citizen of the United States, and a resident of Indianapolis, county of Marion, and State of Indiana, have invented a certain new and useful Dispensing Top for Gontainers; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like numerals refer to like parts.

This invention pertainsto a. dis ensing cap or top for containers, and particularly for use on collapsible tubes containing paste or the like, but which may also be readily adapted for use on cans or similar tubes of paste or powder containers.

The object of the invention is to provide a sliding member for controlling the orifice through which the material may be dispensed, in such fashion that the usual type of screw cap will be avoided with the consequent possibility of losin the same.

The principal feature of t e invention resides in the construction and mounting of the sliding valve or closure member on the top of the container, wherein the maximum degree of eificiency and cheapness in construction may be obtained, and it may be readily assembled.

Another feature of the invention resides in the wedging arrangement of the dove-tail tongue and groove sliding joint, whereby the valve may be slightly wedged in closed position suficient to hold it against accidental opening. This also may be accom plished by roughening the engaging parts of the tongue and groove.

The full nature of the invention will be understood from the accompanying drawings and the following description and claims:

In the drawings, Figure 1 is a plan view looking down on the top of the container showing the valve closure in closing position. Fig. 2 is a central vertical section through the top of the container showing the valve closure in open position. Fi .3 is a section taken on the hue 3-3- of ig. 2. Fig. 4 is a side elevation of the top of the container. I y

In the drawings there is shown what may he a paste tube 10 or any other type of container, such a box or can, having an annular metal top 11 of reduced diameter and connected with the tube 10 by'the tapering of conical neck portion 12. The top 11 is provided with a discharge opening 13 provided with a slot 14. The exposed surface of the top 11 is provided with a diametrically extending dove tailed groove 15 in which is dove tailed, so as to be slidably mounted therein, a valve or closing member 16. Said valve or closing member is provided with a transverse slot 17 adapted to register with the dispensing slot 14 when the valve is moved to one position, as shown in Fig. 2. When the valve is moved to the position, as shown in Fig. 1, the slots 14 and 17 are out of registry so as to prevent the escaping or dispensing of the contents of the container.

The valve member is so arranged with respect to the top 11 that the upper surface of each of them are flush and in the same plane, the dove tailed tongue and groove the operation of the valveerably the end bearing the upright projection 18 so that upon closing the valve there may be a sli ht wedging action which will frictionally old the valve in closed position. In addition to the above-mentioned widened projection, there are oppositely disposed lateral projections 19 soarranged as to engage the adjacent side of the cap 11 for limiting the sliding movement of the valve to closed position. After the valve has been positioned within the top, the opposite end thereof from the projection 18, which comprises the tongue 20, is bent downwardly to provide a stop and limit the movement of the valve in the opposite direction, as well as the thumb piece for pushing the valve into open position. After the tongue 20 has been bent downwardly into as shown, it will be obvious that t e valve is located in slidable relation with the top 11 so that it cannot be removed therefrom and will not disengage the same unless the tongue 20 is again bent upwardly. Each sideof the annular cap 11 is provided with a recess 21 for receiving the tongue 20, and

osi'tion,

into which said tone engages in limiting the movement of the valve, whereby said tongue, when in that position, will be within the periphery of the top and out of the way.

Whereas the top is shown herein as being annular, it is obvious that it may be square without efi'ecting this invention, and that the slots may be of any desired shape or configuration. Furthermore, if desired,

1 there may be substituted for the upwardly extending projection or the finger-hold 18, a downwardly extending tongue 20, as shown. This arrangement would provide a tongue 20 on both ends of the valve for T5 limiting its sliding movement in both directions and retaining the valve in place.

The invention claimed is: A. dispensing device comprising a neck with a dispensing outlet therethrough, a

flat top for said neck having an opening maaeea therein communicating with the interior of said neck,- the outer face ofsaid top having a relatively wide dovetailed groove extending entirely across the same, a plate slidable in said groove and having its outer face flush with the correspond ng face of the said top, widened portions at the edges of said plate at one extreme end thereof to frictionally bind within said groove to positively limit the movement of the said plate in one direction, and to frictionally hold the same against retraction, and the said plate having an opening therein to register with the opening in the top when the plate has reached its limit of movement in the opposite direction.

In witness whereof, I have hereunto affixed my signature.

DANIEL W. LAYMAN.
