Application filed December 7,1905- Serial No. 290.766.
- down and holding by suitable means over the mouth of such vessel a cap or cover having interposed between it and the vessel a disk or washer of packing material; and the ,obj ect of my improvement is to provide for such vessels a stopper of neat appearance and in expensive construction which can be readily applied and removed. I attain this object in the manner illustrated in the accompanying drawings, in which Figure 1 is a perspective view ofthe neck of a bottle and a stopper made in accordance with this invention, showing the outer casing of the-stopper as being partly broken away and the parts in the position which they assume when the stopper is being put .onor taken off the bottle. Fig. 2 is a central longitudinal section of the same, showing the position of the parts when the stopper is closed or seal ed on the bottle. Fig. 3' is a plan-of bottom of stopper, and Fig. 4 is a section of Fig. 3 on the line A B.
Similar figures refer to similar parts throughout the several views.
Referring to Figs. 1 and 2, 1 is the neck of the bottle. 2 is an exterior shoulder on the same. 3 is a disk of cork, rubber, or other suitable material, Figs. 2 and i. 4is a cap,preferably of metal, and having a plurality of depending fingers 5, so shaped as to be capable of gripping under and against the lower surface I of the shoulder 2 when pressed inward toward the neck of the bottle. The particular shape of the depending fingers 5 shown in the drawings is not essential and may be modifled to suit the particular shape of shoulder on vessel to which stopper is to be applied. 6 is an annular member, shown as a sleeve or ring, preferably made of metal, fitted over the cap 4 and adaptedto be forced down over the depending fingers 5 for the purpose of inclosing and pressing them inward. This sleeve or ring is provided at the top with an inwardly-turned flange 7, being substantially a cap with an aperture in the top, and at the bottom with inwardly-turned projections 8, Figs. 3 and 4, to limit its movement upward and downward with relation to the cap 4 and for the purpose of keeping the parts together, this being my preferred form of this member.
In applying the stopper to a bottle the sleeve or ring 6 may be taken between the thumb and second finger, the first finger be ing inserted through the aperture in the top to press downward the cap 4 until its lower edge rests on the inward projections 8, thus causing the depending fingers 5 to extend below the lower edge of sleeve or ring 6 and allowing them to open outward to pass the shoulder on neck of vessel 2, Figs. 1 and 2, thereby bringing the packing material 3, Figs. 2 and 4, in contact with the mouth of thevessel, as shown in Fig. 1. Thesleeve or ring 6 is then forced down over the depending fingers 5, as shown in Fig. 2, thereby pressing them inward against the inclined lower surface of the shoulder on the neck of vessel 2, the efli'ect being to draw the cap 4' downward on the packing material 3 andcompress it against the mouth of the vessel to effect the closure.
To remove the stopper, the sleeve or ring 6 is drawn upward until its lower edge is brought above the depending fingers 5 and the inward projections 8 engaging the lower edge of the cap 4. Both parts may be removed together.
I claim as my invention 1. A bottle or vessel stopper comprising a cap provided with an internal packing-disk, and having depending fingers capable of engaging an exterior shoulder below the mouth of said vessel when pressed inward toward its neck; in combination with an annular member fitted over said cap, and having an inwardly-turned flange at its top, and inward projections at its bottom for the purpose of limiting its movement longitudinally with relation to said cap; and adapted to be forced longitudinally over said fingers to press them inward.
2. A bottle or vessel stopper comprising a cap provided with an internal packing-disk,
and having depending fingers capable of engaging an exterior shoulder below the mouth I of said vessel when pressed inward toward its neck, in combination with a continuous annular member permanently embracing, closely fitting and movable longitudinally and circumferentially on the cap and having a projection engaging the cap to limit its downward movement.
