BOTTLE CLOSURE.

This invention relates to sealing of containers.

This invention has utility when incorporated as a supplemental seal or closure, especially for final capacity determination of bottles requiring stoppers which are essentially herein considered of the narrow neck type, as distinquished from the wide mouth containers, normally sealed by lids.

Referring to the drawings:

Fig. 1 is a side elevation, with parts broken away, of an embodiment of the invention as primarily closed with an embodiment of the closure herein;

Fig. 2 is a plan View of the closure of Fig. 1

Fig. 3 is a section on the line III-III, Fig. 2;

Fig. tie a fragmentary view of the device of the embodiment of Fig. 1, with the closure completed Fig. 5 is a side elevation of a combined cap and stopper embodying features of the invention;

Fig. 6 is a section on the line VIVI, Fig. 5;

Fig. 7 is a view similar to Fig. 6, of a cap type of closure instead of a stopper type, as shown in Fig. 1, or the combined stopper and cap type as shown in Fig. 6; and

Fig. 8 shows an adaptation for wide mouthed ware.

Bottle or container 1' is shown as having opening 2 bounded by lip 3. This opening 2 is shown as providing a seat for primary closure member 4. This member 4-. is preferably of a. resilient material compressible into snug frictional holding relation with the bottle.

In practice, this material of the member i may be cork, rubber or other material exp and ing upon compression so that way 5 therethrough, in which is initially mounted rigid tubular member 6 say as a minute tube of approximating hypodermic needle capacity, may be installed in the bottle with the member 4:; so that this tubular member 6 may have its central opening 7 serve as a vent for the bottled 1. Accordinglythebottlel,as charged with contents, may be subjected totemperature change or have emanations therefrom effective for discharge from the container 1 independently of exerting pressure on the primary stopper member 4.

\Vhen it is desired to discontinue this vent condition, this hypodermic needle type of member 6 may be withdrawn so that passage 5 is collapsed to form filled-in region 8 resisting any discharge or venting operation from the bottle 1. Accordingly, this removal of the rigid member 6 effects a supplemental sealing.

In practice, the lower terminus of this member 6 may be in such flush proximity to the inner end of the member 4 that full venting of may occur, or there may be such desired discharge or residue retained as the extension of the vent member 6 therebelow provides. However, in this extension below, care must be exercised at time of withdrawal to avoid final venting by closing the outer terminus of this vent member 6 at the instance of withdrawal.

lVhile the members may have its frictional seating effective solely from engagement on the inner wall of opening 2, there may be supplemental frictional holding, even with a unitary major stopper' member. Under such circumstances, major stopper member 9 (Figs. 5, 6) is shown herein as provided with yieldable skirt 1O spaced by region 11 from the main closure portion 9 so that this portion 11 may embrace the bottle neck or lip 3. WVith this frictional holding, there may be provided the vent 6 in way 5.

In certain instances, skirt 10 may have the frictional seating means to be reinforced in its holding action, say by clamping means as wire 12, adjusted by holding means 13. This is effective forincreasing the friction clamping or holding action of the skirt 10 upon the outer portion of the bottle neck. Furthermore, in this form there may be an elimination of the central stopper portion 9.

In the instances that the body of this skirt carrying portion 10 be of a different expansion coefiicient than that desired or in order to isolate the container therefrom, there may be provided in this skirted member 10, seat l t for crown seal or washer 15 to abut the terminus of the bottle neck. Here, as in the other instance, there is provision of the rigid vent providing tube 6 in way 5 registering with way 16 in the washer 15. Here, as well as in the device of Figs. 6 and 3, the removal of the vent tube 6 results in an automatic, secondary or supplemental sealing of the closure.

The primary stopper 4:, instead of entering a bottle neck in ware of the narrow neck type, may be seated in the closure, as glass lid 17, of an article of wide mouthed ware 18 as shown in Fig. 8.

The feature of utility herein as to the conby the stopper herein; Thereafter the Vent tube may be removed out of the article, thus effectively sealed for the cooling inte'rvali This cooling interi al of contraction may mean a more snug drawing in or seating of the stopper;

What is claimed and i-tfis desired to secure by Letters Patentis A- bottle stopper comprising a member 00- acting for frictionally engaging a seat in primary bottle closing position said member having a Way therethrough in an expansible and contractable region thereof, and a tube Within said Way open; and removable from said Way, the diametrical size of said tube being so proportioned with respect to the contractable propensity of said region that sa idwvay is completely closed and sealed by Withdrawing said tube therefmm In Witness whereofl afiix my signature.
