4 Claims.

My invention relates to a new and useful improvement in a container and closure therefor, theclosure being of tamper proof and of such a nature as to prevent refilling of the container.

It is an object of the present invention to provide a container and closure therefor so arranged and constructed that a free and easy emptying of the container may be effected, while at the same time, a tampering with the container or closure will effect a destruction of the closure.

Another object .of the invention is the provision of a container and closure therefor so arranged and constructed that a refilling of the container, while the closure is in position thereon, is rendered impossible.

Another object of the invention is the provision of a container and closur therefor so arranged and constructed that when the closure is moved into position on the container, it is automatically locked thereon, and irremoveable therefrom without first effecting a destruction or mutilation of the container or closure.

Another object of the invention is the provision of a closure of this type possessed of a minimum number of parts easily and quickly assembled, and which will be light, durable, economically manufactured, and highly eflicient in use.

Other objects will appear hereinafter.

The invention consists in the various features illustrated and described in the specification and drawing, and such modifications and variations thereof as may suggest themselves to one skilled in the art.

In the drawing, Fig. l is a side, elevational view of a container showing the closure applied.

Fig. 2 is a sectional view taken on line 2--2 of Fig. 1.

Fig. 3 is a side, levational view of the neck of the container.

Fig. 4 is a sectional view taken on line 4-4 Of Fig. l.

Fig. 5 is a sectional'view taken on line 5-5 of Fig. 2.

Fig.6 is a sectional view taken on line 6-6 of Fig. 2.

Fig. 7 is a vertical, longitudinal, central, sectional view through the closure showing it in inverted position.

Fig. 8 is a sectional view, taken on line 88 of Fig. 3.

As shown in the drawing, the container 9 is provided with a neck l0 extending outwardly from one end, this neck being provided with the projecting flange I3. Extending between the threads H and I2 and the flange l3 are abutment plates l4 and [5 formed integral with the neck It. Positioned slightly below and extending beyond the flange I3 is a base-forming flange [6 against which the end of the closure engages when in closing position. As shown clearly in Fig. 4, one side of each of the abutment plates l4 and I5 is formed beveled to provide an undercut l7.

The closure comprises a tubular body l8 which is provided with a tapered portion I9 terminating in an enlarged end portion 20. This tapered portion [9 provides a surface on which advertising or similar display may bedisplayed. This tubular body It terminate in the outer terminal portion 2| which is of slightly less diameter than the main body, and adapted to, receive a cap 22 which may be pressed thereon, and removed therefrom with ease.

The tubular body l8 toward the outer end is provided with the thickened portion 23, on the inner surface of which is formed a plurality of grooves 23', this enlarged or thickened portion 23 serving as an abutment or shoulder on the cup-shaped closure 24 which is insertible as a press fit into the bore 25 of the enlarged portion 23. This cup-shaped closure 24 carries at its open end an. outwardly projecting peripheral flange 26 having an upturned rib or bead 21 at its margin, so as to prevent the thrusting of wires or similar articles inwardly through the grooves 23'. The inner face of the tubular body H3 at the tapered portion [9 is cut away as at 28'to provide a' shoulder against which the outwardly projecting flange 29 of the seat-forming ring 30 may engage, this ring 30 having at its inner end an inwardly projecting flange 3| surrounding the concentric opening 32. Adapted to engage the surface of the flange 3| is a conical valve 33 which, when resting upon the upper surface of the flange 3! so as to close the opening 32, will project at its tapered end inwardly of the cup-shaped closure 24. The ring 30 is pressed into the tubular body as a press fit, and engaging the lower face of the ring 30 is a gasket 34.

The enlarged portion 20 is provided on its inner face with a pair of oppositely positioned bosses 35, the side walls of which are undercut 'as at 36 for receivin an end of an arcuate spring 31 having a tongue 38 pressed outwardly therefrom.

In mounting the closure on the neck, the clothreads H and I 2 spaced from an outwardly sure is assembled as shown in Fig. 2, and then placed downwardly over the neck while the bosses 35 are in relation with the spaces between the threads II and I2. A rotation of the closure relatively to the bottled neck will then bring these bosses 35 into engagement with the under surface of the threads H and [2, which will serve to move the closure axially so as to clamp the ring 3i! against the outer face of the bottled neck, and at the same time, theend of the closure will be brought into engaging position with the flange [6, the flange [3 engaging the inner face of the bosses 35. As it screws into position on the neck, and as the closure moves into its final sealing position, the outwardly punched tongue 38 of the spring 31 will ride over abutment plates i4 and I5, and snap into position behind them so as to prevent reverse rotation of the closure relatively to the neck, thus preventing removal of the closure from the neck. In this manner, the closure is securely locked in position on the neck of the container and in sealing relation thereto. When the container is set in upright position, the conical valve 33 will serve to close the open end of the container neck, and when the container is tipped upwardly, this valve 33 will move downwardly so as to project farther into this cup-shaped closure 24 and permit escape of the liquid from the bottled neck. This liquid will flow around the flange 26 which is of less diameter than the tubular body [8, and then pass through the grooves 23' outwardly of the closure. When the container is moved to upright position, the valve 33 will prevent passage of liquid to the container, so that refilling of the container is thus prevented.

Any undue axial pressure on the closure 24 inwardly of the tubular member l8 will force the closur inwardly against the valve 33 so as to lock it on its seat. Thus the member 24 affords a means of guarding against undue tampering with the closure, and also aflords means for destroying the operativeness of the closure when the container is empty.

It is proposed that the closure be formed. from a composition material, and molded. By forming the closure in this manner, it is but necessary to mold four separate parts, namely, the members I8, 24, 33, and 30, all of which may be easily and quickly assembled in operative posiu tion.

With this form of construction it becomes possible to not only have a container and closure therefor highly efiicient in use, and economically manufactured, but also one which may be rendered highly attractive in appearance.
