Filed oef. 9, 1956, ser. No. 614,896

14 claims. (cl. 1s14o.3)

rI'his invention relates to bottle stopples and in par- Y' trated by Figures 5 or 6. The finger gripping portion 10,

ticular to bottle stopples composed of a plurality of separately fabricated pieces brought together in a unitary stopple assembly. The application is a continuation-,inpart of my copending application, Serial No. 499,554, filed April 6, 1955 (now abandoned). Y

It is known that certain materials are well suited toA stopple a bottle and that others are well suited for finger gripping and external exposure. The bringing together of such materials to form a unitary bottle stopple assembly eilicient in all operating characteristics, conserving of fabricating materials, and economical in manufacture does not lend itself to a ready solution.

It is an object of the invention, therefore, to provide a bottle stopple of at least two separate parts adapted to be integrated in a simple assembly operation.

Other objects of the invention are to provide a bottle stopple which is substantially hollow to conserve materials, which is free of external voids and 'depressions in which the contents of the bottle might become lodged, and which is particularly adaptable to support an appliance such, for example, as a dauber.

ln accordance with ythe invention, there is provided a bottle stopple having separately fabricated finger gripping and bottle engaging portions, the two being hollow. The bottle engaging portion can be of a relatively soft resilient material to effectively stopple a bottle and the finger gripping portion of a relatively hard inflexible material. Complementary frictional wall surfaces are formed on each to facilitate mating with minimum effort but which resist separation with forces of exceptional magnitude. Also, complementary bosses can be formed on the two portions to support an appliance in a mechanically eicient manner, or a shank to hold a dauber can be formed integrally with the bottle engaging portion.

Representative embodiments of the invention from which the above and other objects will be readily apparent are illustrated in the accompanying drawing in which:

Figure l is a side View, partly broken away in vertical section along its diameter, of the finger gripping portion of a bottle stopple;

Figure 2 is a view in horizontal section taken on the line 2--2 of Figure l;

Figure 3 is a side view, partly in vertical section through its diameter, of the bottle engaging portion of' a bottle stopple;

Figure 4 is a view in horizontal section taken onthe line 4 4 of Figure 3 looking in the direction of the arrows;

Figure 5 is a side View, mostly in vertical section along its diameter, of an assembled bottle stopple made up of the.V components of Figures l and 3, with a bottle in which the stopple is inserted and an appliance which the stopple can. carry being shown in broken lines;

Figure 6 is a side view mostly in vertical section along its diameter, of a bottle stopple representing a modifica-l tion of that illustrated by Figures l-5 and inserted'in the neck of the bottle shown in broken lines;

Figure 7 is a perspective exploded view of still another embodiment of the invention;

Figure 8 is a vertical cross-sectionvview of the embodiment shown in Figure 7; and

Figure 9 is a cross-section view taken along theline 9--9 of Figure 8, looking in the directionv of the arrows.

Referring to Figures V1 and 3, there are shown, respectively, a finger grippingportion 10 and a bottle engaging portion 11 adapted to be frictionally united to form a bottle stopple 12' which can be of the'plug type as illuswhich is generally cup-shaped opening toward the mouth ofthe bottle it is to stopple, includes a top portion 13- and, preferably formed integrally therewith, aY tubular side wall 14, the two making up the normally exposed surfaces of the finger gripping portion of the stopple. The exposed surface of the side wall 14 can be formed with flutes 14a to facilitate finger gripping and enhance its appearance.

DisposedV within the wall 14 and preferably formed integrally with the ltop 13Yis an inner tubular wall 15, with the opposed surfaces of the two walls 14Yand 15 constituting frictional side wall meansdefning a channel 16 which, in the event the side wallsare cylindrical, will be toroidal in form. Preferably the opposing surfaces of the walls 14 and 15 are made slightly convergent looking toward the top of the stopple. A plurality of friction ribs 17 are formed on the inner surface of the wall 14, the ribs being relatively shallow and narrow and parallel to the axis of the cup-shaped finger gripping portion 1i) and hence of the entire stopper assembly 12. The. lower end of the tubular wall 15 can be formed with a rounded or tapered lip 18. In4 the event the stopple'is to carry an appliance such, for example, as a dauber, applicator, or the like, there can be formed Within the tubular wall Y15, and preferably depending from the top 13, a boss V19 having a central bore 2) flaring outwardly at its free end 21.

The finger gripping portion 10, which can be formed in its entirety by a single pressing or die operation, is preferably formed of a relatively hard inflexible material such, for example, as polystyrene.

The bottle engaging portion 11, which is also generally cup-shaped opening, in opposition to the finger gripping portion, away from the mouth of the bottle it is to stopple, includes a base portion 22 and, extending upwardly therefrom, a tubular bottle engaging wall 23 which can be slightly divergent moving away from the base. A series of extremely thin, shallow ribs 24, aligned with the direction of insertion into the mouth of theV bottle, can be formed on the exposed'surface of the Y wall 23 to improve the frictional engagement vwith the bottle. .Disposed upwardly of the Wall 23 is friction wall means in the form of a tubular wall 25 of greater diameter than the surface 23 toform a shoulder 26 therebetween. An appliance supporting boss 27, extending upwardly from the base 22, is formed with a central or axial bore 28 to receive an appliance as 'described below.

The bottle engaging portion 11, which can be fabricated by a single die or pressing operation, is formed of a relatively soft and resilient material such, for example, as polyethylene.,

The bottle engaging portion 11 and the finger gripping portion 10 are united by` pressing the tubular friction wall 25 into the channel space 16 defined by the opposed surfaces of the walls 14 and 15, with the friction'ribs 17 embeddingthemselves into the surface of the wall 25, which is tightly pinched at its upper end. The engagement of the friction wall means of the two portions 10 and 11 is facilitated by the relative elasticity or resilience,

of the material `of which the wall 25 is formed relative'.
