CLOSURE FOR BOTTLES AND OTTHER CONTAINERS Filed NOV. 14, 1955 INVENTOR /ATTO.RNEY

Patented July 28, 1936 UNITED? CLOSURE the BOTTLES AND OTHER 1 CONTAINERS PATENT OFFICE Gilbert Jackson, NewYork, N. Y. Application November 14, 1933. Serial No: 697,892 2' Claims. -(c1. 215-22) My invention relates to closures and itnarticularly relates to non-refillable closures for" bottles and similar liquid containingreceptacles. Inmy Patent No. 1,348,116, dated July 27, 1920, I have disclosed a non-refillable bottleclosure or cap which had for its object the preventing of the refilling of bottles after they had been emptied. In said patent there was disclosed a hollow valve member which cooperated with apylihdrical valve seat insertedin themouthof the bottle.- Above the valve and thevalve seat was'positioned a movable ball; The ball-was confined between the valve member on oneside; and at the other side contacted with a concavecontact member;-

As disclosed in said-patent; the valve member was preferably of a porous material; This porous material was of such a nature that the valve. when wet. would attach i-tself' firmly; to its; seat when the bottle'was upright and yet not prevent said valve leaving its seat, when the bottle was inverted. I 1 f 1 p An object of the present invention is to provide a non-refillable bottle closure of the type, as above described; in which the valve member and its associatedparts would be constructed of nonporous material andin which the various; parts of the structure may be; most inexpensively and easily constructed from readily available materials, as for example, plastics; such. as bakelite. Another'object is to provide a; non refillable bottle closure of the type above. described in which the closure is; positively effected and the valve is forced positively to its seat when the bottle is not in inverted discharging position.

Other objects will appear during the course of the following specification. I s

In accomplishing the objects of the present invention i't-has been found most suitable in one embodiment to provide a valve casing. having an upper closure; exteriorly exposed,.and a lower opening to communicate with theinterior of the container or bottle.

The lower portion of the valve casing may be'of a decreased diameter so as to fit conveniently into the neck-of; the bottle, a shoulder being preferably provided on the casing to. limit insertion thereof; a

'Interiorly positioned inthe valve. casing is a valve memberpreferably of hollow construction, the lower end of whichvalve'member is conformed so as to cooperate with avalve seat interiorly formedin the bottom of the casing adja-' cent the interior opening thereof above described. Inthe upper part of said is preferably v provided a: ball which cooperates with a concaved member'inthe upper part of the casing and with a conical or other domed portion at the top of the movablevalve. a

In the accompanying drawing in which is shown one or more of various possible embodiments of the several featuresof the invention,

Fig. 1 is a longitudinal cross sectional view of the non-refillable sealing device of. my invention. Fig., 2 is a transverse sectional vi'ew upon the line 2'2 of Fig. 1'. V

Referring to Fig. I, the bottle or other container Bis providedwith a cylindrical mouth ID. The bottle is adapted to receive alcoholic beverages or any other liquid. to be dispensed.

.Thecylindricalvalve casing l2 is'provided with 7 10. upon the an insert portion l3 ofreduced' diameter, which is inserted in the opening I in themouth or neck of thelbottleB and is stopped by the shoulder 15 on the upper rim I6 of the mouth of the bottle lll'.

The insert portion 7| 3 is provided with a peripheral groove 52 adjacent its lower end. The casing I2 is provided with a lower opening H, the upper part of which is provided with the spherical depression l9, said depression [9. serving as a valve seat to cooperate with the spherical surface 20 on the valve memberZl. j v7 The valve member 2|, as shown in Figskl, 3 and 6, has a cylindricalhollow cup-shaped body 22, exteriorly provided with symmetrically spaced fins 23. The. fins 23 centrally locate the valve within the lower chamber. of the casing l2. i

The lower part of the valve member. 2 l ,as indicated at 25;.projects downwardly past the conical valve seat 19 into the opening I"! .(see Fig. 1)

" The lower portions of the fins are steeplyb'ev- 40 elled, as indicated at 21 (see Figsgl and 6), so that they will clear the valve seat 19.,

As shown in Fig. 3, the fins 23 space the cylindrical body 22 from the walls of thelower chamber 24 of the casing l2 with the formation'of the flow passage 28, which permit ready egress of liquid from the mouth IU of the bottle B past the valve body 2|, when. the valve is lifted from its seatl9. a

V The top 29 of the valve body 22, as shownin Figs. 1 and 6, is flattened and into the upper portion of the cup. 22 is inserted the lower contact element 30 for the locking ball 3|;

The contact element. 30 is provided with a.

' with the upper flattened face 29 or the valve 'member 2|. From the side of'the disk member 3| 'extendr'the fins 32, which are preferably positioned directly above and in alignment with: the 5 fins 23; so aslto-continuethe flow passage 28 rpastzthe structure 30. From the lower part of j l the disk 3| projects the nipple insert 33', which fits into' the upper'part of the cup; opening 34 of the valve body22.

V When the contact member ispressedinto position; a body of air will be confined in the in- 'terior of the cup 34 under a slight pressure. The

7 upper part, of the ball contactmember 3.0'is suitably domed to cause the ball" 3|, as shown in 1 15 Fig. 1, to roll outwardly of the casing l2 against {the interior wall of the middle orintirhediate chamber 35 when the boti' le;is-upright. 5' 2 In the present invention causing the ball. to .roll toward the wallf of the middle chamber 35 of the casing I2.
