UNITED STATES PATENT OFFIOE.

JOSEPH C. ROTH AND JOHN F. BERRIOK, OF BUFFALO, NEW YORK.

CLOSURE OR STOPPER- FOR BOTTLES OR OTHER REGEPTACLES.

Original application filed June 5, 1912, Serial No. ?'01,779.

To all whom- 2'15 may concern Be it known that we, JOSEPH C. Born and JOHN F. BERRIOK, citizens of the United States. residing at. Buffalo, in the county of Erie and State of New York, have invented a certain new and useful Improvement in Closures or Stoppers for Bottles or other Receptacles, of which the following is a specification.

This invention relates to improvements in closures or stoppers for bottles or other receptacles.

The primary object of the invention is to provide a closure, or stopper for the opening in a bottle or other receptacle which when fitted in place automatically locks itself therein and can not be removed without breaking the bottle.

This application is a division of an application filed June 5, 1912, Serial No. 701,779 for improvements in non-refillable bottles.

The invention also relates to certain details in the construction thereof which will be hereinafter described and claimed, reference being had to the accompanying drawings in which a preferred embodiment of the invention is shown.

Figure 1 is a central vertical section through a bottle having the improved closure or stopper fitted in place in an opening in the bottom thereof. Fig. 2 is a transverse section through the bottle on line 2 2, Fig. 1. Figs. 3 and 4 are details of the self locking mechanism.

In refer-ring to the preferred embodiment of this improvement shown in the accompanying drawings in detail, like numerals designate like parts.

The body 1 of the bottle, together with the neck 2 are preferably formed in one integral piece of glass or other suitable material. In the embodiment shown, a round opening which is counter-sunk or enlarged at its lower end is formed in the bottom of the bottle as shown in Fig. 1. A closure or stopper which is made of glass or other suitable material is shaped to fit snugly in the opening and consists of an upper body portion 3 which fits within the circular opening and an enlarged bottom flange portion at which fits tightly in the bottom counter-sunk portion of the opening as shown in Fig. 1. To form a tight joint a thin annular washer 5 is fitted between the annular wall of the opening in the bottle and the circular edge Specification of Letters Patent.

Serial No. 709,386.

of the stopper as shown in Fig. 1; a slight annular groove being formed in the wall of the opening to receive the washer 5 as indicated at 6 in Fig. 1. The closure or stopper is automatically locked in place by spring pressed pins which when the stopper is in place are completely concealed and protected within the body of the bottle and the stopper as shown in Fig. 1.

Referring to Figs. 1 and 2 it will be noted that a series of radial horizontal recesses 7 are formed in the outer or peripheral edge of the closure or stopper and a like series of radial horizontal recesses are formed in the inner surface of the annular wall of the circular opening in the bottom of the bottle body. The recesses in the inner surface of the annular wall are indicated by the nu meral S and register exactly with the recesses 7 when the closure or stopper is properly fitted in the circular opening in the bottom of the bottle as shown in Fig. 1.

lVhile four of the registering sets of recesses are shown in the accompanying drawings, it should be understood that more or less may be utilized as desired.

A series of coil springs 9 are arranged within the inner portions of the recesses 7 and press against the inner ends of pins 10 located in the outer portions of said recesses 7 forcing the outer ends of the pins outwardly into the recesses 8 as shown in Figs. 1 and 2.

In fitting the closure or stopper in place in the circular opening, the pins 10 are first forced inwardly against the tension of the springs and then the closure or stopper is placed in the opening and forced inwardly to the point where the recesses 8 register with the recesses 7 thereby permitting the springs 9 to force the pins 10 outwardly into the recesses 8 and permanently and automatically lock the stopper in place in the opening in the bottle.

It will be observed by referring to Fig. 1, that the slight annular groove formed in the wall of the opening in which the washer 5 is fitted is located exterior and interior to the enlarged outer countersunk portion and eX- tends inwardly from the inner termination of the enlarged countersunk portion to within a short distance of the recesses. The advantage of this construction is that the forcing of the closure or stopper into place in the opening in the bottle also forces the Q Loader? Washer 5 into the groove as the flanged portion of the closure or stopper presses against the outer edge of the washer thereby producing an absolutely air and Water tight joint.

This improved closure or stopper may be employed in connection with a non-refilling mechanism located in the neck of the bottle as illustrated and described in the parent or original application filed June 5, 1912, Serial No. 70l,779, of which this present application is a division, or it may be differently located or arranged or may be altered modified or chai'iged or some or the parts may be altogether omitted Within the scope of the following "Without departing itroin our in vention.

In some instances it may be considered desirable to utilize the improvement in various other types of receptacles and containers for the purpose of securing a permanently sealed package Which cannot be opened Without breaking the package.

Wi e claim A bottle provided With an opening, the

outer portion of which is enlarged or countersunk, a closure or stopper shaped to fit snugly in said opening and having an in ner body which fits within the inner portion of the opening and an outer enlarged flanged portion which fits tightly in the enlarged or countersunk outer portion of the opening; the edge of the inner body of the closure or stopper and the surrounding Wall of the inner portion of the opening having complementary registering recesses, springs in said recesses, locking pins also located in the recesses and adapted to be forced into locking position by the springs; the Wall of the opening exterior to the recesses and interior to the enlarged or countersunk portion being in part slightly enlarged. to provide a narrow annular groove and a thin annular Washer titted in said groove and around the closure or stopper.
