1 Claim.

This invention relates to non-refillable bottles, and its general object is to provide a closure for bottles or other containers, that will allow for the free passage of the contents therefrom, but

prevents refilling after the original contents has been dispensed.

A further object is to provide a closure for a bottle or the like, that renders the same nonrefillable, which can be originally secured to the bottle in an easy and expeditious manner, but cannot be removed therefrom without breakage or damage to the bottle or closure.

Another object is to provide a non-refillable closure for a bottle, that will assure the genuineness of the contents thereof, will retain the contents free from exposure until completely dispensed, and will prevent the contents from flowing therefrom in the event the bottle should fall upon its side, thereby avoiding waste.

A still further object of the invention is to provide a non-refillable closure for a bottle, that is neat and simple in construction, inexpensive to manufacture, and extremely eflicient in operation, use and service.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claim.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:

. Figure l is a longitudinal sectional view taken through the closure which forms the subject matter of the present invention attached to the neck of a bottle, with the parts in normal position.

Figure 2 is a similar view illustrating the fact that the valve remains closed, even though the bottle is tilted on its side to a horizontal position.

Figure 3 is a similar view with the bottle inverted for pouring the contents therefrom and through the closure.

Figure 4 is a detail view of the conical member of the closure.

Figure 5 is a detail view of the valve disk.

Figure 6 is a detail view of the clamping ring.

Figure 7 is a view illustrating the parts of the closure separated and showing the relative position thereof with respect to each other.

Referring to the drawing in detail, the reference numeral l indicates the neck of a bottle which is enlarged exteriorly about the upper end or mouth thereof to provide an annular flange 2 having an annular groove therein, for the purpose of receiving a split resilient ring 3 for securing the closure to the neck in a manner which will be later'described.

The closure includes 'a hollow body 4 of inverted cup-shape formation and the body is provided with a top 5 having centrally arranged thereon and formed therewith an exteriorly threaded nipple 5' for threadedly receiving a cap 6, the nipple acting as an outlet for the contents of the bottle, as it passes through the closure as will be apparent, and the cap 6 may have a gasket 6 therein providing sealing means, so that the contents will remain free from exposure and contamination until completely dispensed from the bottle.

Formed about the lower end of the body 4 is a head I having an annular groove 8 in the interior I surface thereof, and the groove 8 is of a depth to allow expansion of the ring 3, so that when the closure is applied to the bottle, pressure on the ring will cause the same to expand over the flange 2, for disposal in the groove thereof, as shown, therefore it will be obvious thatthe closure cannot be removed from the bottle without breakage or damage to the neck or the closure.

Threadedly secured within the body adjacent to the juncture of the bead thereto, for the purpose of being seated upon the upper edge of the neck or mouth of the bottle is a flat ring member 9, the central opening I 0 of which provides a passage for the contents of the bottle as will be apparent, and the ring member 9 acts as a seat for a disk valve l l which is slidably mounted for vertical movement in the body. The disk valve II is reduced annularly about its outer edge on the lower side thereof, and the reduced portion is provided with relatively narrow arcuate shaped slots I2 therein, as clearly shown in Figure 5, to act as fluid passages, for the contents of the bottle.

Threadedly secured within the body above the ring member 9 and provided with an annular threaded flange l3 for that purpose, is a truncated conical member l4 having a closed top and providing a chamber for a ball weight l5 which is preferably formed from glass or other noncorroding material and normally rests upon the disk valve 1 l to hold the same seated against the ring member, as best shown in Figure 1. The flange I3 is likewise provided with arcuate slots I6 following the shape thereof, as best shown in Figure 4, and which also provides fluid passages for the bottle contents. It will be obvious that the disk valve I l is slidably mounted between thering member and the flange l3, and in order to prevent tilting of the disk valve I provide guide 55 pegs I1, the latter being secured thereto and depending therefrom in annular formation for loose fitting engagement with the wall of the opening of the ring member 9. By reducing the contacting surface of the valve member with respect to the ring member and providing the guide pins I1 and the ball 15, it will be further obvious that it is practically impossible for the valve member to become tilted or stuck in either an open or closed position, therefore free movement thereof to and from its respective positions is assured.

In the use of. my non-refillable closure device, it will be obvious that when it is desired to pour the contents of the bottle therefrom, the cap 6 is removed, and the bottle tilted to the position of Figure 3. When so arranged the ball weight l5 will drop within the chamber provided in the member I4, and allow the disk valve todrop away from the central opening ID of the ring member, therefore the contents of the bottle will pass freely through the opening ID, the slots I2 and I6, and the nipple 5, but when the bottle is disposed to its normal upright position of Figure 1, the ball weight will force the disk valve on-its seat, thereby closing the opening l0, and which will remain closed even though the bottle is tilted to a horizontal position of Figure 2, therefore the contents cannot flow from the bottle should it become accidentally knocked over.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be slidably mounted valve means in said body for controlling the passage of fluid therethrough and being reduced annularly about its outer edge on its lower side, the reduced portion having arcuiate slots therein and providing fluid passages, a ring member threaded to the wall of the body for disposal against the upper end of the con- "tainer-and providing a seat for the valve means to receive the lower side of the latter, a Weight engageable with the valve means for holding the same normally seated, spaced pegs depending from the'valve means in annular formation and arranged inthe opening of the ring member for loose fitting-engagement with the Wall thereof to guide the valve means, substantially truncated conical chamber means for the weight and overlying the same to prevent access to the valve means, an annular flange included in the chamber means and surrounding the chambered portion thereof, and saidflange being threaded to the wall of the body :and having arcuate slots therein providing fluid passages.
