CLOSURE FOR TUBES.

Application filed March as, 1926. serial m. 87,888.

This invention relates to new and novel improvements in containers and while applicable to containers of various forms, it 1s particularly adapted for use to provide a closure for collapsible tubes as are ordinarily employed to hold tooth paste and the like.

Objects of the invention are to provide a container having a closure device of attractive appearance and of simple, durable construction, which may be manufactured at a low cost and which may be quickly and conveniently operated to open or close the container.

A further object is to provide a collapsible tube having a discharge spout provided with a head and provided with a cupped cap hin ed for swinging movement to and from said spout, whereby the same will be distorted during the opening or closing movement and may be forced over the spout to securely seal the discharge opening therein.

The above objects are accomplished and additional ends are attained by the novel construction, combination and arrangement of parts hereinafter described and disclosed in the accompanying drawing, wherein I have illustrated the invention as ap lied to a collapsible paste tube, it being un erstood that the invention is capable of various adaptations and that changes and modifications may be made or resort had to substitutions which come within the spirit of the invention as set forth in the appended claims.

In the drawings like characters of reference are employed to designate like parts as the same appear in any of the several views and in which Figure 1 is a side elevational View showing a collapsible paste tube constructed in accordance with this invention,

Figure 2 is a central, vertical, sectional view of the upper portion of said tube showing the same with the closure cap in an open position,

Figure 3 is a similar view showing the closure cap in a closed position,

Figure 4 is a similar sectional view somewhat enlarged showing the closure cap in a partly closed position.

Figure 5 is an elevational view of the top portion of a tube showing the same with the cap removed.

Proceeding now to a detailed description of the invention with reference to the particular adaptation thereof shown in the drawing, the numeral 5 is used to denote the main body of'a collapsible container. The container is provided -with a conical end wall 6. The end wall 6 is provided with a centrally positioned dischargespout 7 having a discharge opening 8. The discharge spout 7 is provided at the outer end thereof with an annular flange of rounded cross section, thus forming a head 9. The numeral 10 denotes a lug which projects upwardly from the outer face of the wall 6 and which extends into the spout 7, the same terminat ing at a oint immediately below the head 9. The ug 10 is provided on the upper and outer face thereof with a centrally positioned vertical slot 11.

The numeral 12 denotes a cap which corresponds to a portion of a hollow sphere; the cavity of said cap has its largest diameter at a point in close spaced relation to the mouth thereof, the mouth being slightly smaller for a purpose which will be hereinafter described. The cap is provided with an integrally formed fin 14 which projects outwardly and downwardly therefrom, the lower end thereof being received in the slot 11 in which it is hingedly secured by means of the pin 15 which 1s secured in a suitable bore extending through said lug and through said fin. The numeral 17 denotes a packing which is preferably composed of cork, but which may be formed of any suitable material and which is secured in the cavity 16 of the cap. The cap is provided on the upper end thereof with an upwardly projecting portion 18 which may be engaged by the thumb or finger for opening or closing the same. As seen in Figure 2 and Figure 3, the cap may be swung on the pin 15 whereby it will engage the uppervedge of the head 9 on the side opposite the lug 10. As this portion of the head is in the path of the outer edge of the cap, as it is swung on said pivot, it is necessary to apply pressure to distort the cap and force it downwardly upon said head. The cap corresponds in shape to a portion of a hollow sphere slightly larger than a hemisphere and having its greatest diameter at a point spaced inwardly from the mouth thereof. The cap may be forced into a closed position over the head 9 by a swinging movement on the pin 15. The edge of the cap nearest to the hinge is positioned below the greatest diameter of the head. As the cap is forcedintoposition the packing 17 iscompressed; thus closin the ischarge opening 8. When in a close position, t e greatest diameter of the head 9 may be positioned in the greatest diameter of the cap 12 and the mouth of the cap opposite the hinge will impinge the under surface of the head 9 thereby holding the cap firmly in position, with the acking 17 compressed against the outer end of the spout 7.

Attention is called to the dotted line B-'-B whichindicates the path of the cap 12. It will be seen that the cap can; be forced over the head 9 and that the cap will engage the head andhold the same in a closed position.

To open the tube, it is held'in one hand and the thumb is placed against the extension 18 on the cap 12. Pressure is applied, thus moving the cap on the hinge and forcing the mouth of the cap in a swinging ath from said head 9. The cap 12 is provlded at the mouth end thereof with an annular, outwardly projecting bead 19, which is formed thereon to reinforce the cap at its area of greatest distortion.

Having thus illustrated my invention and described the same in detail, what I claim as new and desire to secure by Letters Patent is 1. In a container, a tubular body, an end wall, a discharge spout pro'ecting coaxially therefrom, a. head of roun ed cross section on the end of said spout, a lug formed integral with said end wall and spout, said lug provided on the upper face thereof with' a vertical slot, a cap comprising a portion of a hollow sphere, a fin projecting outwardly and downwardly from said cap, the

said slot and"bei-ng pivotally connected to said lug at a point below said head. In,a collapsible tube, an end wall, a discharge spout projectin coaxially therefrom, a head of rounde said discharge spout, a cap adapted to receive said head, a lug formed integral with said end wall and spout and projecting upwardly from the end wall to .a point immediately below said head, a fin formed integral with saidcap, said fin hingedly connected to said lug at a point below said head, whereby the cap when swung to a closed position will engage said head and be held in a closed position by its inherent resistance to distortion.

3. In a collapsible tube, a head on said discharge s ed to receive said head, a wardly and downwardly from said cap, packing in said cap, a bracing lu formed integral with said spout and exten ing into the end wall of the tube, said lug projecting upwardly from the end wall to a point immediately below said head, said fin hingedly connected to said lug, the portion of the cap opposite said fin arranged to en age said head and be distorted thereby uring an opening or closing movement thereof, the cap when forced to a closed position comlower end ,1of .said fin being positioned in a discharge s out, out, a cap a aptn projecting outcross section onpressing said packing over the end of said spout, the cap being held in said closed position by its inherent resistence to distortion.

In testimony whereof I have hereunto setmy hand.
