Claims.

This invention relates to improvements in closures or stoppers for bottles and other containers, wherein a compressible member is provided with a knob for facilitating the insertion into and re- 5 moval of the closure from a container.

In the closures or stoppers herein disclosed, a compressible member, such as a cork or soft rubber plug, is provided with a knob which may be made of a single piece of sheet material or which may consist of two interlocking shells, which are shaped to form an outer and an inner wall. The inner wall of the knob preferably has protruding parts oompressingly gripping or biting the circumferential surface of the compressible member.

The stoppers or closures of this type now in existence are either inefficient or expensive to manufacture. The present invention aims to provide efficient closures for containers, that can be cheaply stamped out of sheet material.

.20 It is an object of the present invention to provide a closure comprising a combined cap and compressible member in which the cap has an outer shell and an inner shell, the inner shell having two concentrically-arranged spaced-an- ,2 5 nular portions inner and outer, respectively, with a disc integrally united to the inner annular portion at its top, the member being held at its circumferential wall within the inner annular portion; the outer shell having a disc portion overlying the upper edges of the inner and outer annular portions of the inner shell, and a skirt portion overlying the flange of the inner shell.

It is a further object of the present invention to provide a closure comprising a combined cap and compressible member, the cap including a shell having two concentrically-arranged spacedannular portions inner and outer, respectively, the said portions being connected at their bottoms by a flange, and a disc united to the inner .40 annular portion at its top, the member being held having an anti-slip contact wall for fixedly engaging the compressible member.

The foregoing and other features of the invention will become more clearly apparent from the following description, which is descriptive of the 5 preferred embodiments of the invention illustrated in the accompanying drawing. However, the embodiments herein shown and described being for purposes of illustration only, it is to be understood that such modifications may be made, 10 when desired, within the scope and spirit of the invention as claimed.

In the drawing Fig. 1 is a vertical sectional view of a closure, partly broken. 15

Fig. 2 shows a sectional view of an embodiment of this invention, a modification of Fig. 1.

Fig. 3 shows another'modification in vertical cross section.

Fig. 4 representsa closure in section, an em- .20 bodiment of this invention having modified gripping means. E

Fig. 5 is a cross section of a closure, embodying this invention, wherein the knob or cap is made of a single piece of sheet material. 225

Figs. 6, '7 and 8 illustrate stoppers with knobs or caps having various forms of finger grips.

Similar numerals and characters designate similar or. corresponding parts throughout the several views. 30

Referring to Fig. 1, character A designates a compressible member made of cork, rubber or other suitable material in the form of a cylinder. This member A is secured to a cap which may comprise an inner shell Band an outer shell C 35 in interlocking engagement. The inner shell B, which is preferably made in the form of a metal stamping has the circular hollow centralportion [0 receiving the upper portion of the member A and being provided with teeth, corrugations or projections 9 biting into or gripping the Wall of the compressible member A. The rim portion of this cap is flanged outwardly extending upward to form a circular wall ll concentric with W and around the portion l0 but preferably spaced therefrom.

The outer shell C is cup-shaped and applie in inverted position.

The central portion of disc I2 may be depressed providing the recess Ill and the annular rim'or" ridge Ill" abutting the underface M of circular top [3. The circular top edge l3 of the outer wall ll of inner shell B also abuts against the underface M of top 13, with the skirt 26 of cap portion C in tight fit engagement with the circular wall I l of inner member B.

The shells B and C are firmly gripped together by turning in the rim l5 of the outer shell C 5 which is received in the annular recess 25 and presses against the annular shoulder I6 of the inner shell B.

In Fig. 2 the arrangement of the shells B'C' of the knob or cap is substantially similar, though 10 not in detail to that shown in Fig. 1. In this construction, the disk portion l2 of the inner shell B is completely spaced from the underface M of the outer shell C, the outer wall ll accepting the burden of pressure in the interlocking of the shells. The rim l5 of the outer shell C is bent inwardly against the shoulder l6.

Fig. 3 shows the cap of Fig. 2 in a modified form, in which the rim l5" of the outer shell C is turned in to be flatly against the underface of shoulder 16, the two shells being held in interlocking relation.

In Fig. 4, the cap is formed of a Single stamping presenting a cup-shaped shell D having a skirt portion 21 terminating at its bottom in an inwardly bent shoulder or rim 28, the latter extending upwardly breaking into a plurality of petallike teeth I! which terminate in pointed or substantially pointed ends IS. The cork or other compressible cylinder A is forced against the somewhat yielding teeth I! into the recess 19 of the cap. The teeth portions 18 are inwardly bent or projected so as to press againstand bite into the cork A thus insuring a firm grip. The upper or engaging end of the compressible member A rests against the recess bottom 20.

In Fig. 5, the container closure consists of a compressible member, such as the cork A and a cap or knob D. The cup-shaped cap is made in one piece of sheet metal, the rim of the cap being inwardly turned as at ZII and then upwardly as at 22 into a loop, terminating at the underface 20 of the cap and thus forming a circular recess, into which fits the cork A, and an annular air space 23. The inner annular wall 22 is pro vided with a plurality of teeth or projections 9 as in Fig. l.

In Figs. 6, 7 and 8, which show side views of closures, having caps or knobs E, E, E provided with different gripping surfaces; Fig. 6 shows a 5 polygonal knob; Fig. 7 a toothed knob and Fig.

8 a circular disked knob. These knobs may embody any of the constructions shown in the preceding views.

In the drawing and description I have set forth cap or knob parts which are preferably made of sheet metal, as they are believed to be the cheapest and simplest from a commercial standpoint. However, they may be made of any other suitable material.

This application is in part a continuation of my copending application Ser. No. 90,491 filed July 14, 1936.

From the foregoing description taken in connection with the accompanying drawing, it is 5 apparent that an improved simple, practical and inexpensive device for the purpose intended is provided. It is apparent however, that immaterial changes and modifications may be made by skilled persons without, departing from the 70 true spirit and scope of the invention as outpertinent prior art.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
