` comms. (c1. :azi-so) My invention relates to containers. It .has to do, particularly, with collapsible metal containers of the type generally used for holding and dispensing tooth paste, shaving soap and similar products, although there are some features of the invention that may be applied readily to other types of containers. The invention has to do primarily with the dispensing end of the container and with a cap and closure structure therefor of novel form.

t In the prior art, a common form of container of this type has been provided with a discharge neck with threads on the exterior thereof adapted for the reception of the internal threads of a screw cap. This type of container has been subject to several disadvantages. For example, it is ordinarily necessary to use two hands in opening the container and there is always danger of loss of the cap. Therealso arises a danger of hardening of the material to be dispensed, this hardening frequently occurring in the neck of the container and inducing' likelihood of bursting -of the container from the application of sufficient pressure to overcome this hardened condition of the material.

One of the objects of my invention is to provide a container which may be delivered to the consumer in sealed condition, together with a readily available means for opening the container.

Another object of this invention is -to provide a container with a closure structure that may be readily applied, by the user, to-a sealed container and then may be immediately utilized and operated by the fingers of the hand which holds the container, to subsequently open or seal the discharge orifice.

The preferred embodiment of my invention contemplates the provisionl of a container of .comparatively soft material which is provided with a neck that is sealed by means of an integrallyformed disk of soft material. In conjunction with this container, I preferably utilize a closure structure which embodies a closure body portion and a closure cap. This closure body portion preferably carries a means which becomes eifeotive, during the application of the closure structure to the container, to automatically pierce the removed from interference with delivery of the material from the container. Thus, the struedi sealing disk and to so position it that it will be closure structure in condition to regulate supply of this material therefrom.

Various other objects and features of thisinvention will appear as the following description progresses. The preferred' embodiment of the invention is shown in the accompanying drawing wherein similar characters of reference designate corresponding parts and wherein:

Figure 9 is a vertical sectional view of a clo sure device of the form illustrated in Figure 8. .v

In the drawing, my container is shown as comprising a body portion 1 having a neck 2 formed thereon. This neck 2 is constructed and delivered to the consumer with an integral sealing disk 3 that is of comparatively thin cross-section. The

still n an'- "neck 2 is preferably of somewhat heavier cross-v section and has its outer periphery downwardly and outwardly dared, as illustrated in Figures 2 and 3. It will be understood that the body portion of the container may be filled with any suitable material and that this body portion is preferably `of such metal and formation that it may be progressively collapsed from the bottom toward the neck for the progressive delivery of the material from the container.

The closure structure preferably comprises an annular head 4 with an outer skirt 5 and an inner skirt 6, these skirts being separated by an annular space 'l of such form and dimension that it will receive the neck 2 of the container body portion with a wedging fit. It will be noted further that the outer skirt 5 of the closure structure is of greater length than the inner skirt 6.

The inner skirt 6 preferably has its lower edge cut to an oblique line as at 8 so that the side 9 of the edge will extend downwardly substantially further than the side 10 of the edge. Furthermore, this side 9 of the edge is preferably beveled as at 11 so as to produce a shearing edge. Likewise, the external diameter of the skirt 6 is almost as great as the internal diameter of the neck 2.

In the assembly of the closure structure upon the container body portion, this closure structure successively assumes the positions shown in Figures 2, 3 and 5. In reaching the position of Figure 5, the skirt 6 is forced downwardly through the sealing disk 3 so as to partially sever it, in the manner indicated by Figure 4. Continued movement of the closure structure into the position of Figure 5 results in forcing the partially severed disk downwardly along one side of the inner wall surface oi' the neck and the simultaneous bending of this disk so that it substantially conforms to the internal contour of this surface, as indicated in Figures 5 and 6. By the time the position of Figure 5 is attained by the closure structure, the outerv skirt 5 is` rmly wedged upon the downwardly and outwardly ilared exterior of the neck 2.

The head 4 of the closure structure is preferably provided with an inclined annular surface l2 which extends upwardly to lform a comparatively sharp juncture 13 with the inner wall surface 14 of the aperture through the skirt 6. Designed to cooperate with the seat formed-by the juncture of these surfaces is a closure cap that may be generally designated l5. This closure cap is preferably provided with a socket i6 for the reception of a pad 1'7 of cork or some similarly resilient material. The base oi the socket v is formed by a disk 18 which has a slight upward curvature so that the upper surface of the pad is slightly spaced from this disk at and about the center thereof.

The closure cap is attached to the outer skirt of the closure structure by means ci? bowed legs 19. These bowed legs 19 are provided at their lower extremities with curved hook-like portions 2i) which are integrally formed thereon and which project into apertures 2l in the outer skirt 5. The structure of the legs is such as to prevent accidental `release thereof from the apertures 2l and, at the same time, to render them sufficiently resilient to permit the closure cap to ride onto or off of its seat with a snap. Likewise, the resiliency of these leg members is such as to rrnly hold the closure cap in adequate closing relation to its seat when ithas once been placed thereon.

In the modified form of my invention shown in Figure 7, the container body is designated v and is provided with a cylindrical neck 26 whose exterior is threaded as at 27; This neck 26 is likewise provided with a 'sealing disk, such as that shown in Figure l. ln this modified form, the closure device takes substantially the same form as the closure device illustrated in Figures 1, 2, 3 and 5 and described in the preceding paragraphs. However, it varies slightly in that threads are provided on the inner surface of the skirt 5 intermediate the length of the annular space '7. This threaded portion does not extend below the inner skirt, thereby permitting the skirt to be forced downwardly through the sealing disk 'to partially sever it in the manner heretofore related, prior to the engagement of the threads with the threaded neck of the tube.

In both instances, the same procedure is followed in displacing the sealing disk, only, in the latter instance, the securing of the cap on the neck is obtained by engagement of the threaded surfaces, rather than by means of a wedging action, characteristic of the type rst described.

The modified form of closure device, shown in Figures 8 and 9, takes the form of a screw cap 28 that is also adapted to be employed with a container having a threaded neck. This screw cap is provided with a skirt 29 having internal threads 30 and a central plug 3l having its lower end pointed as at 32 and being spaced from the internal surface of the skirt 29. The space between-the exterior of this plug 3l and the lnte'rior of the skirt 29 is sufficiently great to accommodate the thickness of the neck 26 and also of the sealing disk whose parts are designated 33.

The operation of this modified structure will be apparent. The screwing of the cap onto the container will ultimately cause the plug 31 to pierce the sealing disk and to force the parts 33 thereof downwardly along the internal sidel walls of the neck. Likewise, these' parts 33 will be automatically bent to conform to the internal contour of the neck, with the result that they will be placed in a position of minimum interference with the delivery of the material from the container.

It will be seen from this description that I have provided a superior form of container which may be delivered to the consumer in completely sealed condition and which is automatically opened by the mere application thereto of the closure device which, subsequently, is to control the delivery of material tl'ierelrom.v Obviously, the closure device of my preferred form may be applied to the neck of a container by means of threads, as in the form shown in Figure 7. In any of these structures, including the form shown in Figures 8 and 9, the placing of the closure structure upon the container not only punctures the sealing disk but it moves the parts thereof to a position oi non-interference with the delivery of material from the container. In the preferred form described, the closure structure of my container is operable with the fingers of the hand which holds the container proper and possesses the feature of simplicity of operation in addition to the feature of simplicity of application. As a matter of fact, with any of the structures which I have shown, the closure structure may be applied to any container of the form indicated, thus making it possible for the manufacturer to sell the sealed body portion alone and without the closure structure, if desired.

Having thus described my invention, what I claim is:

i. Container structure comprising a body portion, a neck forming a part of said body portion and having a duct therein, a sealing disk for saidA duct, a closure, an outer skirt portion carried by said closure structure andv designed to embrace said neck, and an inner skirt prtion carried by said closure and designed to be forced through said sealing disk to open said duct, said inner skirt portion having a delivery aperture therethrough. l
