Unite 3,067,897 CLOSURE FOR RECEPTACLE Roberto Incera, Rodriquez 56, Santos Sciarez, Havana, Cuba; Hilda Mederos de Incera, heiress to Roberto Incera, deceased Filed Dec. 15, 1959, Ser. No. 859,659 2 Claims. (Cl. 215-25) This invention relates to a novel and useful closure cap construction, and more particularly to a closure cap construction which is specifically adapted to be used as a closure for bottle-type receptacles and the like for preventing unauthorized injection of liquids into the receptacle.

Although the closure cap construction of the instant invention is specifically adapted to comprise a closure cap for bottle receptacles in which alcoholic beverages are contained, it is to be understood that the closure cap construction may be most conveniently used for the purpose of restricting unauthorized injection of liquids into various other types of bottle-type receptacles and the like containing liquids.

In some instances the owner of a tavern or restaurant which serves alcoholic beverages and the like desires to have a means whereby his customers may be assured that they do not receive diluted beverages. Many methods have been used in an attempt to reach this end including the use of apparatus which is capable of registering the number of times a bottle is removed from its position on a storage shelf and also recording its weight each time it is replaced upon the shelf. Although this method makes it extremely inconvenient and timeconsuming for a tavern employee or the like to serve a customer a diluted drink in a manner whereby the employee is able to save that portion of the beverage which is not served to the customer, it is still possible for the employee to serve the customer a diluted beverage by diluting each drink individually.

It is therefore the main object of this invention to provide a closure cap construction which may be afiixed to the neck of a bottle-type receptacle in a manner whereby its unauthorized removal may be easily detected and which will make it practically impossible for the beverage within the receptacle to be diluted without removing the closure cap construction from the bottletype receptacle.

A further object of this invention, in accordance with the preceding object is to provide a closure cap construction having an upper valve mechanism and a lower valve mechanism for preventing the flow of liquid into the receptacle to which the closure cap construction is secured while the receptacle is in an upright position.

Still another object of this invention, in accordance with the immediately preceding object, is to provide a closure cap construction having two check valves arranged in series and positioned in such a manner whereby one valve mechanism will completely enclose the other valve mechanism thereby making it next to impossible to manually manipulate the inner valve mechanism.

Yet another object of this invention is to provide a closure cap construction for bottle-type receptacles and the like which may be secured to the opening of the receptacle and which is provided with a threaded neck portion with which either a threaded closure cap construction comprising a part of the invention may be threadedly engaged to provide a suitable covering for the closure cap construction or with which the threaded closure cap originally supplied with the bottle receptacle engaged.

It is still a further object of this invention to provi-de a closure cap construction having a pair of check valve mechanisms which are operable independently of each other but which have a means for interconnecting the inner valve mechanism with the outer valve mechanism so that the outer valve mechanism may engage the inner valve mechanism to close the latter upon the closing of the outer valve mechanism.

A final object to be specifically enumerated herein is to provide a closure cap construction for bottle-type receptacles and the like which will conform to conventional forms of manufacture, be of. simple construction and easy to operate so as to provide a device that will be economically feasible, long lasting and simple to use.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, whereing like numerals refer to like parts throughout, and in which:

FIGURE 1 is a perspective view of a bottle-type of receptacle to which the closure cap construction comprising the present invention is secured;

FIGURE 2 is a perspective view similar to FIGURE 1 but of the upper portion of the bottle-type of receptacle and showing the closure cap construction secured thereto but with the closure cap therefor being removed;

FIGURE 3 is an exploded perspective view of the closure cap construction showing the manner in which it is assembled;

FIGURE 4 is an enlarged vertical sectional view of the upper portion of the bottle-type of receptacle shown in FIGURE 1 taken substantially upon the plane indicated by the section line 44 of FIGURE 1;

FIGURE 5 is an enlarged vertical sectional view similar to that of FIGURE 4 but showing the bottle-type of receptacle in an inverted position and the valve mechanisms of the closure cap construction in an open position with the closure cap therefor being removed;

FIGURE 6 is a horizontal sectional view taken substantially upon the plane indicated by the section line 6-6 of FIGURE 4;

FIGURE 7 is a horizontal sectional view taken substantially upon the plane indicated by the section line 77 of FIGURE 4; and

FIGURE 8 is a horizontal sectional view taken substantially upon the plane indicated by the section line 8-8 of FIGURE 4.

Referring now more specifically to the drawings, the numeral 10 generally designates the closure cap construction of the instant invention which is shown in FIG- URE l secured to the neck portion of a conventional type of bottle receptacle generally referred to by the reference numeral 12. The receptacle 12 is provided with a diametrically reduced neck portion 14 which has formed thereon a radially extending retaining flange 16 which is of conventional design. The neck 14 is provided with an opening 18 which is in communication with the interior of the receptacle 12.

Referring now more specifically to FIGURES 3 through 5, it will be seen that the closure cap construction It) includes an upper valve mechanism generally referred to by the reference numeral 20 and a lower valve mechanism generally referred to by the reference numeral 22. The lower valve mechanism 22 includes a cylindrical valve cage or body generally referred to by the reference numeral 24 which is provided with a radially extending retaining flange 26 on its upper end. A bore 28 is formed through the cage 24 and the upper end of the valve cage 24 is provided with a counterbore 3 30. The lower end of the bore 28 is provided with a plurality of radially extending openings 32. Secured to the lower end of the valve cage 24 is a depending journal block 34 which is provided with a centrally disposed bore 36 which is in axial alignment with the bore 28 and counterbore 30. The shoulder 38 between the bore 28 and the counterbore 30 is provided with an upstanding centrally disposed circumferential flange 40 which comprises a seating surface for the undersurface of the head portion 42 of the valve element for the lower valve mechanism 22 which is generally designated by the reference numeral 44. The valve element 44 is provided with a depending cylindrical valve stem 46 which is slidably disposed through the bore 36. With particular attention directed to FIGURE 4 of the drawings it will be noted that the lower valve mechanism 22 is slidably received within the opening 18 formed in the neck portion 14 of the body 12. A resilient washer 48, which may be conveniently constructed of cork, is interposed between the upper surfaces of the retaining flange 16 and the undersurface of the retaining flange 26. In this manner, if there were provided means for retaining the lower valve mechaism within the opening 18 it will be noted that unless the valve element 44 were manually manipulated, the entrance of a liquid into the receptacle 12 would be restricted inasmuch as the valve element 44 is urged to a closed position engaged with the flange 26 by gravity whenever the receptacle 12 has its neck portion inclined upwardly.

The upper valve mechanism 20 also includes a cylindrical valve cage or body which is generally referred to by the reference numeral 50. The upper valve cage 50 is provided with a bore 52 which has disposed therein a perforated restricting partition 54 having a centrally disposed bore 56 formed therein which is in alignment with the large bore 52. The valve cage 50 is provided with a diametrically enlarged base 58 which is adapted to overlie the washer 48 in such a manner whereby the bore 52 will form a continuation of the counterbore 38. Formed in the lower end of the bore 52 is a shallow counterbore 60 which snugly receives the retaining flange 26 whereby the upper valve cage 50 will be maintained in axial alignment with the lower valve cage 24. The upper valve mechanism 20 is also provided with a valve element which is generally designated by the reference numeral 62. The valve element 62 is provided with a head portion 64 having a suitable resilient washer 66 secured to its undersurface which is adapted to engage and overlie the upper end of the valve cage 50. The valve element 62 is provided with a stem portion 68 which is cylindrical and is slidably disposed in bore 56. The lower end of the stem 68 is threaded as at 70 and has threadedly engaged therewith an abutment block 72 whose purpose is to be hereinafter set forth. The outer surfaces of the upper portion of the valve cage 50 are provided with suitable threads 71 with which an internally threaded conventional form of closure cap 73 may be threadedly engaged for the purpose of sealing the interior of the closure cap construction 10 from the ambient atmosphere.

To secure the closure cap construction 10 to the upper portion of the receptacle 12 a metallic sleeve 74 is disposed about the base 58, the washer 48 and the retaining flange 16 with the upper and lower ends of the sleeve 74 being crimped over the base 58 and the retaining flange 16 respectively. It is to be understood that a seal of plastic or other suitable materials can also be used for the purpose of securing the closure cap construction 10 to the neck 14 of the receptacle 12. Also, it is to be noted that the dimensions of the upper portion of the valve cage 50 and the threads 71 thereon may be of a size to enable the conventional type of threaded closure cap of the receptacle 12 to serve as the closure cap 73 if the receptacle 12 is provided with such a closure cap.

In operation, the closure cap construction 10 is first secured to the neck 14 of the receptacle 12 as heretofore set forth whereupon inclination of the receptacle 12 toward a horizontal position if it is full or toward a downwardly inclined position if it is partly filled will enable the fluid contained within the receptacle 12 to enter into bore 28 by means of openings 32 whereupon it will urge valve element 44 from engagement with the flange 40 thereby communicating the interior of the receptacle :12 with the interior of the valve cage 50. The liquid entering the valve cage 50 will then urge the valve element 62 toward an open position whereby the liquid may then be poured form the receptacle 12 in the usual manner. Particular attention is directed to FIG- URE 5 of the drawings wherein it may be seen that after the valve element 44 has been moved slightly toward an open position the head 42 thereof will engage the abutment block 72 to further assist in the movement of the valve element 62 toward an open position. As the receptacle 12 is returned to an upright position gravity will urge both the valve element 44 and the valve element 62 in a downward direction until they reach a closed position. It is to be noted that if the valve element 44 resists the downward pull of gravity upon the righting of the receptacle 12 because of friction between its moving parts, the downward movement of the valve element 62 will assist to effect downward movement of the valve element 44.

It is to be noted that the apertured partition 54 will allow the passage of liquid but that it will discourage any attempts to manipulate the lower valve element 44 toward an open position while the receptacle 12 is in an upright position.

Further, it is to be noted that any convenient material may be utilized in the construction of the closure cap construction 10 but that it may at the present he most conveniently constructed of a plastic material which is not subject to corrosion from coming into contact with various types of liquids which might be served as a beverage.

Further, not only will the closure cap construction 10 restrict persons from diluting the beverage contained within the receptacle 12 but it will also prevent the refilling of the receptacle 12 with a beverage of inferior quality.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
