  • a cylindrically shaped cork 9 is provided on the exterior surface of the casing l adjacently to the flange 8 to assure a tight fit between the casing and the inner surface of the neck of the bottle and to prevent leakage at this point.
  • An annularly shaped washer it made of any suitable material is provided between the flange B and the closure 3 to seal the connection between these parts.
  • the lower end of the casing I is provided with an inwardly extending flange 30 H upon the upper side of which is mounted an annularly shaped washer l2 which may be made of cork, rubber or any other suitable material and which has an outside diameter substantially the same as the inside diameter of the casing so that 35 it fits snugly in the casing.
  • a disc-shaped valve element Seated upon the washer I2 is a disc-shaped valve element it adapted under normal conditions to close the passageway formed by the inner walls of the washer l2 and the flange l l and having an outside diameter slightly less than the interior diameter of the casing i so that when it is in opened position the fluid contents of the bottle may pass between the outer edge thereof and the interior surface of the casing.

  • the discshaped valve element H has a diameter substantially the same as the valve member I3 so that any liquid flowing into the casing from the bottle will pass between the outer edge of such member and the interior surface of the casing I.
  • valve element I3 and I1 may be approximately twice that of the valve element I3 and the valve element I1 is provided with vertically disposed channels or grooves 20 on its outer edge which enable a greater flow of the liquid past such element and which enables it to be readily inserted into or removed from the casing past the stops I8.
  • the valve elements I3 and I1 may be made of any suitable material such as non-corrosive metal, phenol plastic material, glass, porcelain or cork.
  • the bottle closure 3 is provided with an arcuately shaped projecting portion 2
  • the two depending portions of the seal 23 extend down below a relatively deep annular groove 24 formed on the neck of the bottle between the annular bead 25 and 26.
  • the destructible seal may be made of cellulose, metal foil, fabric or any other suitable material such as is ordinarily used for this purpose and may be weakened by a scoring provided at the point where it is folded on the arcuately shaped portion 2
  • the outer de pending portion of the destructible seal 23 may be provided with a pair of parallel cuts extending lengthwise of the seal and through which the metal band 21 passes so that a part of said outer portion of the seal is positioned outside of the band, as shown in Figs. 1 and 2.
  • the diameter of the inner side of the band should be approximately the same as the diameter of the inner wall of the groove 24 so that it tightly wedges the two depending portions of the destructible seal 23 against the inner wall of the groove thereby permanently maintaining those portions of the dcstructible seal in place on the bottle and preventing anyone from mounting a new destructible seal on the bottle.
  • the band 21 is constituted of metallic material and has such rigidity of constitution and form that on application of prying pressure applied between the wall of the bottle and the inner periphery of the band, the band will maintain its shape and position until the bottle is so deformed or destroyed as a result of the prying pressure as to be incapable of further use. While the band may be made in one piece, I prefer to make it of two pieces, one end of each piece being welded together in a manner well known in the art when the parts thereof have been mounted in the groove. As shown in Figs.
  • the continuity of the groove 24 about the neck of the bottle is broken by a partition of glass 28 which extends transversely across the groove from the lower head 26 to a point substantially midway of the groove and is integrally formed with the lower bead 26 and the inner wall of the groove.
  • the two ends of the arcuately shaped pieces of the band 21 which are joined together at this portion of the groove intermediate the partition 28 andthe upper wall of the groove, as is clearly shown in Fig. 3, are reduced in cross-section so that such end portions of the band cooperate with said partition to prevent any rotational movement of the band on the bottle. It is to be understood that other partitions or stops may be positioned in the groove, as may be found necessary.
  • the above arrangement provides the bottle with a double seal which will prevent anyone removing the closure 3 of the bottle and tampering with the contents thereof since it is exceedingly difficult and practically impossible to remove the permanent seal or ring 21 and place a new destructible seal 23 on the bottle and that portion of the destructible seal which is permanently maintained in the external groove 24 by the band 21 will serve as notice to the customer that the bottle originally was provided with a destructible seal and that the contents of the bottle has been tampered with.
  • the consumer may readily open the bottle by destroying the destructible seal 23 and unr' screwing the closure 3. With the closure removed, the consumer is then enabled to withdraw the casing 'I together with the elements contained therein and to pour out the liquid contents of the bottle in the ordinary manner.

  • the liquid passes from the casing '6 through the space between the valve element H and the inner side of the casing 5, through the opening 5 in the closure 3, down through the pipe 45 in the casing 35 which discharges the liquid through the outlet 4
  • the measuring cup has been filled to the desired height, atmospheric conditions are restored in the casing 35 thereby stopping the flow of liquid from the bottle.
  • the dispenser then pulls the handle 41 downwardly against the tension of spring 48 thereby enabling him to remove the cup from the device.
  • a customer buying a drink from a bottle provided with a device of the invention is assured that he is getting the genuine article as he knows that the valve arrangement within the bottle prevents anyone from putting a spurious liquid in the bottle and the double seal 23, 21 which is in prominent position on the bottle will notify him when the bottle has been tampered with.
  • the washer i2, the valve elements l3? and i1 and the spring H are contained within a. hollow cork casing 5
  • the casing 5i has an external diameter substantially the same as the inside diameter of the neck of thebottle so that it snugly engages with the inner wall of the latter and performs the functions of an ordinary cork.

16 Claims.
This invention relates toimprovements in devices for liquid containers which are adapted to prevent tampering with the contents thereof and has for its principal object to provide a simple, inexpensive and practical device of the indicated character which will only permit the removal of the liquid contents of the container with which it is associated and which will apprise the consumer when an attempt has been made to adulterate the contents of the container or substitute a spurious product.
Other objects well as thenovel details of the construction of a device embodying the invention will become apparent after consideration of the description herein below set forth taken in conjunction with the accompanying drawings in which similar reference characters identify similar parts in the several views and in which Fig. 1 is a front elevation of the top portion of a bottle provided with a device made in accordance with the invention; Fig. 2 is a central vertical section taken at right angles to Fig. 1; Fig. 3 is a rear elevation of Fig. 1 partly in section; Fig. 4 is a top plan view of the bottle closure; Fig. 5 is a section taken along the line 5-5 of Fig. 2; Fig. 6 is an elevation showing the valve elements which control the removal of the liquid from the container; Fig. 7 is an elevation partly in section showing the casing for the valve elements illustrated in Fig. 6; Fig. 8 is a top plan view of the casing shown in Fig. '7; Fig. 9 is an elevation partly in section showing the means for extracting the liquid from a bottle provided with my novel device; Fig. 10 is a central vertical section of the top portion of a bottle fitted with a modified form of the invention; Fig. 11 is a top plan view of the closure shown in Fig. 10; Fig. 12 is a section taken along the line l2--I2 of Fig. 10; Fig. 13 is a top plan view of an element of the device shown in Fig. 10; Fig. 14 is an elevation of anotheriorm of the invention showing it in position for insertion into a closure sealed in the neck portion of a bottle, the latter being shown in vertical section; Fig. 15 is a top plan view of the mouth of the bottle shown in Fig. 14; Fig. 16 is a vertical section of the parts shown in Fig. 14 after the device has been inserted into the mouth of the bottle; Fig. 17 is a top plan view of the device shown in Fig. 16 and Fig. 18 is a section taken along the line l8|8 of Fig. 16.
Referring more particularly to Figs. 1 to 8 of the drawings, the reference character l designates the neck of a bottle which is provided at its top portion with an external screw thread 2. A closure cap 3 having an internal screw thread t is screwed on the thread 2 provided on the bottle neck. The closure cap maybe made of any suitable material and when made of a brittle substance such as phenol plastic material may be formed with a discharge aperture 5, as shown in the 5 drawings which when not in use may be closed by a small cork 6. Positioned within the mouth of the bottle is a hollow cylindrically shaped casing I made of non-corrosive material and provided at its upper end with an outwardly extending flange 8 adapted to seat on the top edge of the neck of the bottle and support the casing within the mouth of the bottle. A cylindrically shaped cork 9 is provided on the exterior surface of the casing l adjacently to the flange 8 to assure a tight fit between the casing and the inner surface of the neck of the bottle and to prevent leakage at this point. An annularly shaped washer it made of any suitable material is provided between the flange B and the closure 3 to seal the connection between these parts. It will be seen that with the above described arrangement the liquid contents of the bottle will be prevented from leaking out between the casing I and the inner surface of the bottle neck or the casing and the closure cap 3 either during shipment or handling of the bottle or when the contents thereof are being sold to the consumer as will be hereinafter more fully explained. The lower end of the casing I is provided with an inwardly extending flange 30 H upon the upper side of which is mounted an annularly shaped washer l2 which may be made of cork, rubber or any other suitable material and which has an outside diameter substantially the same as the inside diameter of the casing so that 35 it fits snugly in the casing. Seated upon the washer I2 is a disc-shaped valve element it adapted under normal conditions to close the passageway formed by the inner walls of the washer l2 and the flange l l and having an outside diameter slightly less than the interior diameter of the casing i so that when it is in opened position the fluid contents of the bottle may pass between the outer edge thereof and the interior surface of the casing. A vertically disposed spring it which is secured to a reduced portion B5 of the valve element It maintains the valve element in closed position when the liquid contents of the bottle are not being withdrawn. The upper end of thespring It is secured to the reduced portion it of an upper disc-shaped valve element it which is retained in the casing l by means or the inwardly projecting stops it provided on the inner surface of the casing adjacent its upper edge. The spring it is of such size and stre that in its compressed condition between the valve elements I: and I1, it exerts sufllcient pres sure on the valve element I3 to maintain the I latter seated on the washer I2 even when the bottle is tilted to a pouring position. In accordand permit the liquid contents of the bottle to flow past such element and into the casing. The discshaped valve element H has a diameter substantially the same as the valve member I3 so that any liquid flowing into the casing from the bottle will pass between the outer edge of such member and the interior surface of the casing I. The
. thickness of the valve element I'I, however, may
be approximately twice that of the valve element I3 and the valve element I1 is provided with vertically disposed channels or grooves 20 on its outer edge which enable a greater flow of the liquid past such element and which enables it to be readily inserted into or removed from the casing past the stops I8. The valve elements I3 and I1 may be made of any suitable material such as non-corrosive metal, phenol plastic material, glass, porcelain or cork.
It will be seen from the above that when the said parts are in position in the mouth portion of the bottle, the lower valve member I3 in the casing 7 is seated tightly on the washer I2 under the compression of the spring I4 thereby preventing any liquid in the bottle from flowing out through the passageway formed by the inner walls of the washer I2 and the inwardly extending flange I I at the lower end of the casing I. As the tension of the spring I 4 on the lower valve member I3 is suificiently great so that said element cannot be displaced by the weight of the liquid or by shaking the bottle in inverted position it will be seen that the liquid contents of the bottle are sealed therein and cannot be taken out until the bottle is placed in a suitable device for the removal of the liquid contents thereof as will hereinafter be more fully explained. Furthermore, no liquid can be inserted in the bottle as any attempt to force liquid into the bottle will only result in seating the valve element more tightly on the washer I2.
The bottle closure 3 is provided with an arcuately shaped projecting portion 2| having a slot or opening 22 through which extends the inner portions of a destructible sea1'23. The two depending portions of the seal 23 extend down below a relatively deep annular groove 24 formed on the neck of the bottle between the annular bead 25 and 26. The destructible seal may be made of cellulose, metal foil, fabric or any other suitable material such as is ordinarily used for this purpose and may be weakened by a scoring provided at the point where it is folded on the arcuately shaped portion 2|. Seated in the groove 24 and encircling the depending portions of the seal 23 is a substantially heavy, indestructible and non-removable band 21. The outer de pending portion of the destructible seal 23 may be provided with a pair of parallel cuts extending lengthwise of the seal and through which the metal band 21 passes so that a part of said outer portion of the seal is positioned outside of the band, as shown in Figs. 1 and 2. The diameter of the inner side of the band should be approximately the same as the diameter of the inner wall of the groove 24 so that it tightly wedges the two depending portions of the destructible seal 23 against the inner wall of the groove thereby permanently maintaining those portions of the dcstructible seal in place on the bottle and preventing anyone from mounting a new destructible seal on the bottle. The band 21 is constituted of metallic material and has such rigidity of constitution and form that on application of prying pressure applied between the wall of the bottle and the inner periphery of the band, the band will maintain its shape and position until the bottle is so deformed or destroyed as a result of the prying pressure as to be incapable of further use. While the band may be made in one piece, I prefer to make it of two pieces, one end of each piece being welded together in a manner well known in the art when the parts thereof have been mounted in the groove. As shown in Figs. 2 and 3 of the drawings, the continuity of the groove 24 about the neck of the bottle is broken by a partition of glass 28 which extends transversely across the groove from the lower head 26 to a point substantially midway of the groove and is integrally formed with the lower bead 26 and the inner wall of the groove. The two ends of the arcuately shaped pieces of the band 21 which are joined together at this portion of the groove intermediate the partition 28 andthe upper wall of the groove, as is clearly shown in Fig. 3, are reduced in cross-section so that such end portions of the band cooperate with said partition to prevent any rotational movement of the band on the bottle. It is to be understood that other partitions or stops may be positioned in the groove, as may be found necessary.
It will be seen that the above arrangement provides the bottle with a double seal which will prevent anyone removing the closure 3 of the bottle and tampering with the contents thereof since it is exceedingly difficult and practically impossible to remove the permanent seal or ring 21 and place a new destructible seal 23 on the bottle and that portion of the destructible seal which is permanently maintained in the external groove 24 by the band 21 will serve as notice to the customer that the bottle originally was provided with a destructible seal and that the contents of the bottle has been tampered with.
The consumer, however, may readily open the bottle by destroying the destructible seal 23 and unr' screwing the closure 3. With the closure removed, the consumer is then enabled to withdraw the casing 'I together with the elements contained therein and to pour out the liquid contents of the bottle in the ordinary manner.
When the contents of the bottle, however, are to be sold in small quantities to a consumer as in the case where liquor is to be served over the bar, the seal 23 is left untouched and the cork 6 is removed from the opening 5 in the top of the closure 3. The bottle is then placed in inverted position on a dispensing device such as is illustrated in Fig. 9. As shown in the indicated figure, the dispensing device may comprise a supporting base 30 which may be secured to a support by means of screws 3I. Intermediate the upper and lower ends of the base is secured thereto a bracket 32 provided at its outer end with a substantially annular shaped support comprising an upper annular portion 33 and a lower annular portion 34 of smaller diameter and integral therewith. The lower portion 34 is adapted to support the cylindrically shaped neck portion of a flask shaped casing 35 which is provided at its lower end with an externally threaded annularly shaped connection 36. The casing 35 may be made of ,glass,,metal or any other suitable material. Positioned within the upper annular portion 33 is a plug or closure 31 made of compressible material such as soft rubber and having a reduced portion which extends into the neck portion of the casing 35.. The plug 31 is provided on its upper end with an annular recess 38 adapted to receive snugly the closure 3 of the bottle. The bottle is supported in inverted position on the plug 31 by means of a pair of horizontally disposed-spring arms 39 which are fixedly secured at their inner ends to the base so. Extending axially of the plug 31 is a vertically disposed pipe 40 which communicates at its upper end with the recess 38 and forms a direct connection between the opening 5 in the closure 3 of the bottle and the interiorof the casing 35. The lower end of the pipe is positioned close above a rigidly formed outlet 4!, supported centrally of. a rubber diaphragm 42 and extending therethrough. The diaphragm 42 is integrally formed with an annularly shaped coupling member 42 adapted to screw on the threaded connection 35 at the lower end of the casing 35. Positioned beneath the diaphragm 42 is a measuring cup 43 which is supported by apparatus adapted to keep the mouth portion of the measuring cup in tight engage ment with the underside of the diaphragm 42. The apparatus for accomplishing this may comprise a bracket 44 secured at its inner end to the supporting base 30 and provided at its outer end with an opening through which extends a rod 55 havingat its upper end a cup holder 55 for supporting the measuring cup and at its lower end a handle 4'l adapted to be grasped by the dispenser. A spring 48 which is positioned between the cup holder 46 and the bracket M and encircles the rod 45, maintains the former in upward position so that the measuring cup is held tightly against the diaphragm 52. The cylindrically shaped neck portion of the casing 35 is provided with an opening 415 which is in alignment with an open end of a pipe 50 integrally associated with the lower cylindrically shaped portion 34 of the bracket 32, the other end of said pipe being connected to some means (not shown) for supplying a vacuum in the casing 35, such as a pump or a suction device operated by water. It will thus be seen that when the bottle is mounted in inverted position on the plug 3'5, as above described and shown in Fig. 9, so that the opening 5 in the closure 3 is in alignment with the opening in the upper end of the pipe Mi supported by said plug and a vacuum created in the casing 35 through the pipe 50, the vacuum will cause the valve element l3 in the casing '1 contained in the bottle to be drawn downwardly into opened position, as viewed in Fig. 9 and cause the liquid contents of the bottle to be drawn through the openings in the flange H and washer l2, through the space between the valve element l3 and the inner side of the casing and into the casing i. The liquid passes from the casing '6 through the space between the valve element H and the inner side of the casing 5, through the opening 5 in the closure 3, down through the pipe 45 in the casing 35 which discharges the liquid through the outlet 4| into the measuring cup 45. When the measuring cup has been filled to the desired height, atmospheric conditions are restored in the casing 35 thereby stopping the flow of liquid from the bottle. The dispenser then pulls the handle 41 downwardly against the tension of spring 48 thereby enabling him to remove the cup from the device. A customer buying a drink from a bottle provided with a device of the invention is assured that he is getting the genuine article as he knows that the valve arrangement within the bottle prevents anyone from putting a spurious liquid in the bottle and the double seal 23, 21 which is in prominent position on the bottle will notify him when the bottle has been tampered with.
In the modified form of the invention shown in Figs. 10 to 13, the washer i2, the valve elements l3? and i1 and the spring H are contained within a. hollow cork casing 5| suitably secured to a closure 52, the combined casing 5i and closure 52 having the outward appearance of an ordinary cork closure. In this case the casing 5i has an external diameter substantially the same as the inside diameter of the neck of thebottle so that it snugly engages with the inner wall of the latter and performs the functions of an ordinary cork. The bottom wall 53 of the casing 5| is substantially thicker than the side walls thereof so that a suitable support is formed for the valve elements. Dueto the fact that the closure 52 itself confines the elements within the casing it is unnecessary to provide stops such as the stops it in the preferred form of the invention. As the top surface of the upper valve element ll seats against the under surface of the closure 52 because of this arrangement, it is necessary that the top surface of such element be provided with grooves or channels, such as the transversely disposed grooves 54 illustrated in Fig. 13 which communicate with the vertically disposed grooves 20' provided on the side surfaces of such element in order that the liquid drawn into the casing Si by the dispensing device will be enabled to flow out through the opening 5' provided in the closure 52. The destructible seal 55 in this form of the invention may extend across the top of the closure 52 so that the depending portions thereof are positioned on opposite sides of the bottle neck, such depending portions extending down below the annular groove 56 formed in the neck of the bottle and partly positioned therein under the substantially heavy, indestructible and non-removable metal band 51.. The upper annular bead 58 on the neck of the bottle and the outer edge portions of the closure 52 are preferably recessed so that the depending portions of the seal 55 can lie against the outer surface of the neck of the bottle and so that the seal is prevented from slipping ofi the bottle. A perforation 59 is provided on that portion of the seal 55 which extends across the closure 52 so that the cork 5' may project therethrough.
The cooperating elements in the device of my invention instead of being wholly assembled on the bottle at the filling establishment as shown in Figs. 1 to 13, may be in part assembled on the bottle when the latter is filled and in part assembled on the bottle at the place where the contents thereof are to be sold in small quantitles to the consumer. In accordance with this form of my invention, instead of assembling the valve elements in the bottle at the filling establishment the bottle is closed by a cylindrically shaped cork 55 which is adapted to be inserted in the bottle so that the upper edge thereof lies flush with the top of the bottleas shown in'Fig.
14. A cap 65 adapted to threadedly engage with the screw threads provided on the mouth portion of the bottle is then screwed into position on the latter. The cap 56 is provided with a centrally disposed opening Bl which exposes the an annular recess within which is secured a disc 13 having a diameter'substantially the same as the opening 61 in the cap 66 and constituted of sufllciently strong material to prevent tampering with the liquid contents of'the bottle through the opening in the cap 66. Integrally formed with the lower edge of the cap is an outwardly projecting extension 68 provided with an elongated opening 69 through which extends the inner portion of the destructible seal I0, the two depending portions of said seal being sealed in the external groove H on the neck of the bottle by the permanent seal 12 as hereinbefore explained. The bottle which is sealed in the manner above described is sold in this condition to the trade.
The device of my invention which controls the removal and insertion of fluid in the bottle is sold separately to the trade in combination with a cork-removing device which, when once in-- sorted into the bottle, can only be removed therefrom by smashing the bottle. As shown in Figs. '4 and 16 this combined arrangement comprises a casing 14 provided at its upper end with a discharge nozzle 15 and at its lower end with an outwardly extending flange 16 which seats on the upper surface of an outwardly extending flange TI provided on the upper end of a vertically disposed tubular member 18. The outer edge portion of the flange ll is turned over the flange 16 of the casing 14 so that said casing is securely held in position on the flange l'l. Positioned within the casing 14 and seated on the flange I1 is an annular washer 19, the opening of which is normally closed by the lower valve element 80 under tension of the vertically disposed spring 8| which is secured at its upper end to the upper valve elezrent 82. The organization of the parts within the casing 14 is similar to that already described in the preferred embodiment of my invention. Secured within the lower end portion of the tubular member 18 is a hollow cylindrically shaped member 83 hav ng two depending arms 84 which are vertically disp sed in spaced parallel relation, the distance between such arms being substantially greater than the diameter of the tubular member 18. The depending arms 84 are each provided at their lower ends with a downwardly extending reduced portion 85 which termnates in a point. The arms 84 are also each provided with a longitudinally extending opening or slot 86 through which a V-shapcd spring tensioned member 81 is adapted to move. Each of the members 81 is mounted on an arm 84 so that the apex thereof is normally positioned outwardly from the arm supporting it, the lower end of said member being supported on a pin 88 rotatably mounted on bearings provided at the lower end portion of tl-e slot in said arm and the upper end of said member being provided with an upwardly extending portion 89 adapted to engage with the inner side of said arm and limit the outward movement of the member 81. A spring 90 which is suitably connected to said member 81 and said arm 84 normally tends to keep the member in outward position and yieldingly resists inward movement of the same. I
It will be seen that when the port'cns 85 of the arrangement above described, are in erted in the cork and downward pressure is applied, the shoulders formed by the portions 85 and the lower end portions of the arms 84 engage with aoeaaac the upper surface of the cork and force the latter downwardly into the bottle.. During the passage of the arms 8| through-the neck of the bottle, the spring-tensioned members 81 are forced into retracted position against the tension of the springs 90 by the inner surface of the neck portion of the bottle. When the members 81 have passed the neck of the bottle, however, they are moved outwardly by the springs 90 and abut against the inner surface of the shoulder of the bottle as shown in Fig. 16, thereby preventing the removal of the device from the bottle. The tubular member 18 is provided with an annularly shaped cork 92 for tightly sealing the device in the neck of the bottle and which in its passage into the bottle turns the inner edge portion of the bottle cover downwardly around the top of the bottle as shown in Fig. 16. It will thus be seen that when the device is inserted in the bottle, the arrangement is fundamentally the same as that shown in the preferred form of the invention and the liquid contents of the bottle can be dispensed in small quantities by means of the apparatus shown in Fig. 9 in the manner above described. The portion 85 of the arms 84 hold the cork securely within the interior of the bottle so that it cannot interfere with this operation. In order to remove this arrangement from the bottle for use on another bottle, it is necessary that the bottle be smashed as the spring-tensioned members 81 will not permit the removal therefrom through the neck of the bottle.
While I have shown and described the casing 1 in the preferred form of the invention as being supported on the mouth portion of the bottle, it is obvious that it may be permanently or removably secured to the bottle closure 3 in any suitable manner such as by cement, or by turning the outer edge portion of the flange upwardly and inserting it into a recess provided in the closure 3 or by providing such upturned portion with a screw thread which is adapted to be threadedly received by the closure 3. The valve elements comprising the inner seal of my vacuum non-refillable closure may have other forms than that illustrated and may be so associated with the coiled spring that the inner seal operates only under a predetermined degree. of
vacuum. The lower valve element 13 may be externally threaded and adapted to loosely screw into screw threads provided in the inlet opening in the lower end of the casing 1. In this case the coiled spring may be eliminated and the upper valve element made suificiently heavy so that it maintains the lower valve element closed when the contents are not being removed from the bottle. When the bottle is placed in inverted position on a suitable vacuum device, however, the upper element will fall away from the lower valve element and the contents thereof can be drawn out through the passage formed by the screw threads on the element I 3 and the inlet opening of the casing. Means may be associated with the lower valve element l3 to enable the weight of the liquid to assist in moving such element to opened position. The upper element l1, instead of being movably positioned in the casing, may be made of cork or rubber and fitted tightly into the casing. In this case the element may be grooved as shown in Fig. 13 or passages may be provided through the element. The opening in the bottle closure may be omitted, in which case a hole is punched in the closure just Drlbr to placing it on the dispensing device. The
hole in theclosure whether formed in the closure or produced after the bottle is sealed need be no more than a minute opening thereby making it impossible to tamper with the parts comprising the inner seal through such opening.
The opening in by other means closure fitted over the bottle than a cork,
the bottle closure.
closure may be closed such as a rubber In the modified form of the invention shown in Figs? 14: to 18, the 1:)
closing the bottle but solid closure instead. In this case, the device for controlling the ottle need not have a cork for may be provided with a liquid is in addition provided adjacently tothe reduced pointed portions 85 with a round cutter which comes into contact with the closure after the said pointedportions or prongs have been forced into the closure.
The invention is also susceptible to other changes in the construction and arrangement of the parts without the appended claims and may be departing from the scope of used to equal advantage on containers made of a material other than glass.
The invention is of particular value for bottles or containers filled with wines, liquors, bever-' ages, toilet products and pharmaceutical products as it maintains the original mellowness, odor or strength of such liquids until they are used.
