This invention relates to closures and particularly to closures and closure structures especially adapted for use in connection with bottles, jars, or similar fluid receptacles.

Among the objects of the present invention which is simple in construction and operation and'readily suited to economic manufacture.

7 Another object of the presentinvention is to provide a closure adapted for substantially 'manently secured by wire or the like, to the rceptacle instead ofth'e usual shipping 010- sure.

Anotherobject of the invention is to provide a closure supporting structure whereby the closure may be retained in sealing position with respect to the receptacle and Wheree by releasing from such position will automatically cause the closure to assume a position free from interference with the discharge of material from the receptacle;

Other objects of the invention include t h combination and interrelation of parts whereby the Whole forms a convenient readily attachable and detachable simple structure, and as the closure is retainedincombination with the receptacle, contamination z of the closure is prevented'when sterileliq- .uids are used and thus the device isparticu- I 1 'larly adapted for medical-use, andan easily locked closure is obtained by simple down ward pressure on the knob thereof.

With these and other objects of the present inventionin view, reference maybehad to the accompanying'drawings, in which Figure 1 is a perspective view of one form of my present invention;

Fig. 2 is a verticalsectional view of that form of the invention illustrated in Fig. 1;

trated in Fig. 3, and

Fig. 3 is a top plan View of the closure base as will be hereinafter described;

Fig. 4 is a side elevation of. the base illus- Fig. 5 is team perspective view. of a I sealing bushing adapted for %LSS 0O1a.tlO11 W1th said base- Referring'more particularly to the-drawiii-gs, the preferred embodiment of my invention" herein; illustrated, includes a base illustrated in detail in Figs. 3 and l. The base includes an elongated horizontally posit tioned transversely extending-member 11, depending from which there is provided a tub ular sleeve 12 crimped throughthe aperture of the rnember 11,and is adapted to be surrounded by a sealing bushing 13, as illus trated in Fig. 5, which is preferably formed of cork, rubber, or other suitable semi-flexibleniaterial. The tubular portion or sleeve '12 and the bushing 13 are. adapted to be receved within the neck of a receptacle which has been illustrated-'in'the" form of a bottle 1 1. The tubular portion 12 and'bushing 13areremovably secured within the neck of the bottle and sealed relatively thereto through the bushingJB, which through its V expansive character retains the base thereon.

Associated with one extremlty of the meme p ber ll, a spring. closure supporting'member l5 'is' 'provided, hingedly associated therewith asindicatedat 16. 7 The member 15 is preferably formed of spring metal, such as steel or the like, and is bowed upwardly, the free 1 end being adapted I for engagement" with the free end of the member '11, as indicated at 17.2. The removableengagement of the free end of the; bowed member .15 with the; ex: tremity of the member'llis provided for by an inwardly turned portion 18 thereof with 'which'is associated agfinger, manipulating BX- 'tremity, 19. lfThefi central portion of 'the bowedmemberf15iscentrally apertured as at 20as shown in F. ig 2, toreceive therethrough afthreaded member .21, the head "offwhichis positionedidownwardly and engages a washer 22 through the medium of which a" compressible stopper 23' is engaged in association withthe threaded member 2l-and the bowed member 15. Theupper-end of the threaded member 21 is provided with a knob 24, preferably formed of heavy metallic material, the knob being secured in association with the bowed member 15 and the threaded member 21 by the provision of a threaded retainer associated with the member 21, or the'knob 24 may be threaded to accomplish the purpose of the retainer 25.

The stopper 23 is preferably formed cork, rubber, or other suitable compressible material, whereby the member may be forced into tight engagement with the upper portion of thetubular member 12 of the base 10,

and thus prevent the flow of liquid there through. The stopper'23 is covered by a metallic cap 26 which will hold the stopper 23 with the member 21. The heavy characteristic of the knob 24 is adapted to control the position of the bowed member'15- when the stopper isout of engagement with the tubular portion of the base The arrangement is such that the center of gravity of the bowed member 15 is outward form the hinged portion 16 thereof after slight upward movementof the knob 24. Thus after disengagement of the-portion 18 from the point 17, the'bowed member 15 will pivot about thehinge 16 and assume the position indicated in dotted lines in Fig, 2.

The springy characteristic of the bowed member 15 and the configuration thereof with respect tothe portion 11, is such that for engagement of the portion 18 at-17, downward flexing of the bowed member 15is necessary. Thus the stopper 23 is retained within the tubular portion 12, and upon releasing the catch portion 18, a reflexing ac-. tion of the bowed member 15 takes place, thus urging the removal of the stopper 23 from the tubular portion 12 and throwing the bowed member 15 backwardly, whereby the center of' gravity will be outward from the hinged portion 16, as hereinbefore described, whereby the bowed member and its associatedstopper and knob assume the posi- 'tion indicated by the dotted lines in Fig. 2.

Locked closure of the device is accomplished by simple downward movement of the knob 24 andpressure thereon.

' From the foregoing 1t will be readily seen that my'present inventionprovides an imof a transversely extending base carried thereby, and a closure member pivotally associated with one end of said base and engageable with the opposite end of said base, said member having a flexible arm and a closure plug carried by said arm.

2. In a closure for receptacles, a receptacle-engaging element including a transversely-extending base, a flexible closurecarrying member pivotally attached to one end of said base, said closure-carrying member having a catch at its free end adapted to engage the corresponding free end of said base thereby retaining said closure-carrying member in a flexed position on said base.

3; In a closure for receptacles, a receptacle-engaging element including a transversely-extending base provided with a 1ongitudinal depression to form a spout, a flexible member pivotally attached to one end of said base,,a stopper element centrally secured to said flexible memberat one side thereof, a weighted manipulating element centrally secured to said flexible member at the other side thereof, a catch formed by the proved automatically operable bottle stopper which may be readily associated with various kinds and configuratlons of receptacles w thout clamping 7 means or extra securing devices. iii It will be readily understoodthat'the in vention as herein disclosed may undergo various changes andmodlficat ons and the full useor equivalents be resorted to wlthoutjdeparting from the spirit or scope, of t pended claims.
