2 Claims.

This invention relates to bottles or flasks, especially of the non-refillable type, and its main object is to provide a duplicate set of intermediate chambers and passageways and interposing valves co-acting with one or more floating members, which will allow for the dispensing of the liquid from within the bottle, and to prevent any tampering for refilling same.

Other objects of the invention will appear in the following description of the specification with appended claims, accompanied by the annexed drawings, in which Figure 1 is a vertical cross-section of the bottle.

Figure 2 is a preferred modification of the bottle.

Figure 2a is a detail section on the line 2-2 of Fig. 1.

Figure 3 is a similar section on the line 33 of Fig. 1.

Figure 4 is a fragmentary view in perspective of the neck portion.

Figure 5 is a perspective view of the float member.

Figure 6 is a modification of the neck portion.

Figure 7 is a view in perspective showing the bottle in a dispensing position.

Figure 8 is a further modification of the neck portion.

Figure 9 is an enlarged section of the valve seat.

Figure 10 shows an alternative form of valve.

Referring to the drawings, the numeral I indicates the body portion of a bottle or flask or of any desired receptacle, having a neck portion 2, provided with a mouth 3 into which the usual cork' is secured. At the bottom of the mouth is a bridge-like structure or lugs 3a, protruding over a chamber 5, which connects with a port or opening 5a into a second chamber 6, having a float member 'I to close and open said port. The chamber 6 has also a bridge-like retainer 8 having openings 8a, and is fixed slightly above a passageway Ill leading into a third chamber I I which is also provided with a retainer 8 and openings 8a above a second passageway I2 leading into the inner chamber I3 of the bottle.

Interposing between said bridge-like structure or retainer 8 and the passageways I and I2 is a stopper or valve I4 having an enlarged head portion I and a shank extending into the passageways as shown, and arranged so as to provide a sealed joint on the seat I6 of the flanged portion F. These valves are made of glass or porcelain or any other suitable material so that the weight will operate them on and off the seat I6 by gravity, or automatically close and open the passageways I0 and i 2, when the bottle is not in use, and when it is in the dispensing position, respectively.

The float member I as shown in perspective of Fig. 5, is made of cork or the like, to give it buoyancy when in contact with any liquid in attempting to refill the bottle, and has pin like stems or similar means for guidance in the port 5a, when in the act of closing and opening same. The valves or stoppers I4 are provided with channels or grooves i9 to allow the free flow of liquid therethrough from the passageways when the bottle is in the dispensing position as shown in Fig. 7.

The inner chamber of the bottle has at the bottom thereof, a plug 2! for the purpose of filling the bottle through the opening 22, after which the plug is fused into the opening 22 in the usual manner of glass fusing. Other means for filling may be adopted, but this is the general practice of filling bottles of the non-refillable types.

In Fig. 2 is a preferred modification of the neck portion of the bottle over that just described, in which the mouth 31) has a perforated member or cap portion 25 above a float la within the chamber 21, the float being slidable in the retainer or cap 28 through the port 29 which leads into a chamber 641, within which is a retainer 38 having open ings 3 I. Interposing there between a bushing B is a Valve or stopper I la which may or may not have a washer or gasket 32 for sealing the passageway Illa leading into a second chamber 33, also provided with a retainer and openings 3 I. A float member Ibis operative in the chamber 33 through port 34 of the retainer 35, and interposing below is a second valve or stopper Ma arranged in the bushing B, having a passageway IZa leading into the inner chamber of the bottle. This arrangement of parts as above described allows for the bottle and neck portions to be moulded into equal half portions and fused together on the center line as at 36.

It is to be noted that all the retainers and bushings are fixed into, for example, annular grooves separately before the fusing of the half portions P and Pa of the bottle, and are watertight by cement or by other means desired. It is to be noted that the bushings B and B are solid members and allow for grinding of the seat where the valve or stopper Ma contacts, thereby providing an accurate water-tight joint thereat. This neck portion may be circular in section other than square as shown in Fig. 3, but it is understood that I do not confine myself to any particular shape, or the manner of securing the retainer or bushings.

In Figure 6 a modification is shown of the neck portion whereby all the parts are embodied in a sleeve or split coupling 2e made preferably of porcelain or other non-transparent material, and is secured into the neck portion 2 by glass cement or by other suitable means. A passageway IZb connects the coupling with the inner chamber of the bottle as shown. This inserted coupling has all the parts for free flowing of liquid from the bottle and for preventing the refilling of same, either in Fig. 1 or of the preferred form shown in Fig, 2, and is secured together by packing cement on the line 29, or by screws if so desired.

In Fig. 8 is a modification of the neck portion 2a being separately secured onto the bottle la, which may or may not be made of brown glass or non-transparent material, while the bottle is of transparent material, for observance of the color of the contents therein.

In Fig. 9 is an enlarged view of the valve or stopper l4 and the contacting seat l6, whichmay be of a very slight surface, so as to provide little possibility of the valve sticking thereto, and the weight of the valve is to be such as to allow the free movement from the seat l6 when in the dispensing position as shown in Fig. 7. It is to be further understood that I may Prefer some tendency of the valves or stoppers to stick onto the valve seats l6, l6 and I6 when the bottle is emptied of its original contents, there being no liquid inside to assist in opening same, after which the longer time it remains empty it may seal itself thus.

In Fig. 10 a ball valve or stopper 39 is shown, and may be used if desired, but the elongated or shank valve or stopper l4 and. Ma ofier a valve of an unusual type but it is understood that I may adopt any valve orstopper other than shown without departing from the spirit of my invention.

The bottle as shown in Fig. 1 has a fusing line at 40 and oif to one side, so as to provide means for grinding the valve seats IS on a full solid portion (shown in Fig. 4), and for drilling if desired from within the chambers 6 and II. A blind seam edge 4| may be added to be symmetrical with the seaming and fusing line 42 when the flat sided portion P is fused together on the other moulded portion Pa.

It is to be understood that the arrangement of the parts and the intermediate chambers in duplicate sets, and the continuous valve and float arrangement, make it a difiicult task for tamper into the neck of the bottle, and an additional float as shown in Fig. 2, would assist further in the non-refilling of the bottle.

Variable means other than heretofore described that will assist to perfect a better or accurate non-refillable bottle, may be adopted if such means come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to: secure by Letters Patent of the United States, is as follows:

1. In a non-refillable bottle having a neck portion adapted to receive separable bushings therein; each of said bushings provided with a passageway having a ground valve seat; an elongated solid valve having an enlarged head portion adaptable for contacting slightly on said ground seat; said valve having a shank portion provided with channels or grooves; a float member having pin like projections orsimilar means adaptable for said float member to slide within a port opening provided within one of said bushings; each of said valves providing a double precaution of preventing said bottle being filled with any suitable liquid when in the unused position; said cork member providing a further precaution of refilling; each of said channels or grooves of each valve being adaptable to allow the free flow of liquid from within the said bottle when in the dispensing position.

2. In a non-refillable bottle having a neck portion provided with independent chambers connected by passageways having therein a solid valve member with a shank end integral with an enlarged head portion adaptable to close each of said passageways; said neck portion provided with a reduced mouth opening leading into a chamber having a perforated member above another chamber containing a float member; said float member adaptable to close and open a port opening therewith leading into one of aforesaid independent chambers provided with one of said valves; said perforated member adaptable to prevent tampering with said float member, each of said valves and float members adaptable for preventing the re-filling of said bottle; and for the free flow of liquid from said bottle when in the dispensing position.
