z claims. (ci. azi-e1) This invention relates to a closure device and particularly to a device used in connection withl closure caps for sealing an opening in a can, drum or other container. More specically, the invention relates to a device which is applicable for closing an opening in a container, drum or other receptacle after' the sealing cap has been removed.

Openings in cans, drums and other containers are frequentlyclosed by the application of a closure cap, such as a snap-on cap. These caps are provided with liners of paper, cork, rubber,

etc., and t over the openings in the containers and seal the containers. One type of cap, as an example, is a cap which is commonly known as the U-Pressit Cap. 'Ihis latter cap ts closely over the `lip of the opening to be sealed and is made tight by the application of pressure on the edges of the cap which causes the top of the cap to spring up and the edges to contact tightly around the lip of the opening. While such a cap fits tightly when sprung in place, it does not make a tight it over the opening when unsprung or loosened. This is especially true when the cap closes an opening fitted with a pull-out spout. If the cap is used to cover the end ofy the spout while it is pulled out, it is too loose and does not perform the function of tightly closing the opening in the spout.

'I'he present invention eliminates the difculties and disadvantages inherent in caps of the above mentioned type, and the primary object of the invention is to provide a cap with a stopper-like projection which iits into the opening in the container or the spout depending upon the container opening, and which has a body or projection of suitable length forming a stopper which seals the openingand keeps the capxin Another object of the invention is to provide a new andimproved one-piece yieldable and ilexible stopper made of soit rubber-like material which is received within a closure cap and which has a yieldable and integral depending projectionwith a movable spout and having the invention applied thereto.

Fig. 2 is a detail sectional view of a container having the spout pulled out and showing the position of the cap relative to the spout opening.

Fig. 3 is a detail sectional view showing one type of sealing closure fastened in position about the opening in the container.

Figs. 4 to 'Z inclusive are detail perspective views of various forms of Stoppers which may 68 be used in connection with different kinds of closure caps.

'Ihe particular container herein shown for the purpose of' illustration has an enclosing wall 10 and a top 11 which may be inclined as indicated 7e at 12.Y An upstanding neck 13 surrounds the opening 14 in the top andv carries a movabl spout l5.

The spout '15,has crimped upper and lower edges 16 and 17 respectively and its movement E6 is limited by the inturned annular depending flange 18. When the spout is in the position shown in Fig. 1, the rolled portion or bead 1 will engage the part 19 of the ange 18, but when the spout .is pulled out to the position shown in Fig. 2, the annular member or lower bead v1'7 will engage the portion 20 of the iiange 18. A pivoted handle 21 may befastened to the upper bead 16 for use in pulling the spout from the neck 13.

A closure 22 which may be any kind of a seal cap, but which is herein shown as a U-Pressit Cap, is adapted to have its exterior surface or flangev 23 engage an annulus or annular groove 24 in the exterior surface of the neck-13. I When the cap 22 is placed in sealing position, the outer rim or ange 23 of the cap is pressed inwardly causing the inner edge 25 to be received in the groove. When fastened in position, the top 26 will bow outwardly. When it is de- 95 sired to remove the cap 22, the top 26 is pressed inwardly, when it will bow as shown at 27 in Fig. 2. This bowingI causes the iiange 23 of the cap to spread outwardly and release the edge 25 from the groove 24. Ordinarily the cap l0. I

loose for the spout. l"

To provide a closure seal for the opening in the container as well as a stopper for the opening in the spout, it is preferable that the combined liner and stopper 28 be made of flexible material so that it will give to a certain degree to conform with irregularities of the spout, and particularly give sufficiently to permit its application when the handle 21 is in the position shown in Fig. l'. This member 28 may be xed to the closure 22.

The combined liner and stopper is preferably made in one piece of flexible rubber-like material, and has a liner portion 29 and a stopper or holding portion 30, Figs. 4 to 7.

The form of liner and stopper 28 shown in Figs. 1, 2 and 4 comprises an annular projection 31, Fig. 4, which has a recessed opening 32 in its top, Fig. 1, the bottom of which has a closure 33. As shown in Figs. l, 2 and inclusive the member 28 may be molded in one piece, the liner 29 amounting to nothing more than a peripheral ange 34 which engages the top of the neck 13. As the side ange 31 and the closed bottom 33 are made integral with the flange 34, it can readily be seen that an air-tight seal is had `when the cap 22 is fastened in place, also a stopthe opening vcap is snapped in position in the spout.

In Fig. 6, the disc 35 is provided with cross arms 38, the outer edges 39 of which are adapted to engage the inside surface of the spout to hold the member 29 in position in the spout, the disc 35 acting as the closure foi` the spout as well as a liner for the neck.

In Fig. 7 the disc 35 is provided with circumferentially spaced exible pins 40. These pins are for the same purpose as the cross arms 33 previously mentioned relative to Fig. 6. These pins engage the inner surface of the material of the spout and frictionally hold the member 28 in position so that the disc. 35 will form a closure across the opening in the spout.

It is preferable that the projection or pro-` Leaders Jections 30 be made exible so that they will give a certain degree to permit the combined liner and stopper to be used for the different purposes intended.

The invention provides simple and inexpensive means for providing a sealing washer or disc and a closure member as well as providing a stopper for the opening when the closure member or cap is released from the container opening. Other types of caps can be very advantageously used in connection with the combined liner and stopper in addition to the type shown.

Changes may be made in the form, construction, and arrangement of the parts without departing from the spirit of the invention or sacricing any or" its advantages, and the right is hereby reserved to make all such changes as fairly fall within the scope of the following claims.

The invention is hereby claimed as follows:

l. .A container having an opening, a neck surrounding the opening, a spout slidable inwardly and outwardly in the opening in the neck, means for limiting the movementof the spout, a closure cap for engaging the outside of the neck and adapted for removable replacement with respect to said neck, a member adapted to be arranged in the cap to seal the opening in the neck when the cap is arranged in closed position, and means integral with the member and adapted to lt inside of the spout and frictionally engage the inner walls of the spout.

2. A container having an opening, a neck surrounding the opening, a spout slidable inwardly and outwardly in the opening in the neck, means for limiting the slidable movement of the spout, a closure cap for engaging the outside of the neck, a. member adapted to be arranged in the cap to seal the opening in the neck when the capis arranged in closed position, and a projection integral with said member and spaced from the inner side Walls of the closure a distance sumcient to provide a stopper for the spout Without the edges of the closure cap contacting with the outer edges of the spout, said projection adapted tov t inside of the spout and frictionally engage the inner walls thereof to provide a stopper for the spout when the spout is slid in its outward pouring position.
