The invention relates to an apparatus which is attached inside a bottle, container or can. With the use of the present invention, when the bottle is inverted the fluid inside the bottle flows out of the bottle smoothly.
When a bottle is inverted the fluid inside it flows out irregularly. This is a result of air alternately entering the bottle and fluid exiting the bottle at the name of the bottle. This results in an irregular and uneven flow. The present invention provides a means for air to enter the bottle through an opening in the side of the bottle, thereby avoiding the inward flow of the air interfering with exiting fluid flow from the neck of the bottle. This provides for a smooth for a flow of fluid from the bottle. An internal reservoir avoids leakage of the fluid when the bottle is inverted.
In general, prior inventions have not combined the elements of a reservoir in the neck of a bottle with an air inlet (venting) hole in the side of the neck. In Jamieson, U.S. Pat. No. 4,938,395, a vent hole is placed in the side of a bottle. Alder, U.S. Pat. No. 4,967,922, discloses a bleeder valve mechanisms inside a bottle to control fluid flow. Talbert, U.S. Pat. No. 3,173,566, discloses a drinking straw mechanism to control flow, combined with a side vent.
Offman, U.S. Pat. No. 5,449,098 (a previous invention by this inventor), discloses the element of a reservoir in the neck of a bottle with an air inlet (venting) hole in the side of the neck. However, according to this prior art, the air inlet hole must be pointed upward to avoid leakage from the reservoir.
The object of the invention is to facilitate the smooth flow of fluid from an inverted bottle regardless of the direction in which the air inlet (venting) hole is pointed.
Another object of the invention is to prevent leaking of liquid from an inverted bottle with smooth flow of fluid, when drinking or pouring from the bottle.
The intention of the drawings attached to the application is not to limit the scope of the invention and its application.
The drawings are intended only to illustrate the invention and they constitute only one of its many possible implementations.
Typically in the use of the invention, as in
The reservoir 7 is affixed to the inside opening of a flat disk shaped rim 8 as in
In another embodiment of the invention, as in

As seen in
The air then flows 10 up the tube 9 to the air cavity above the fluid 4. This air creates a pressure on the top of the fluid 14. The tube 9 is affixed to the end of the reservoir 7, at an angle, such that when the bottle is inverted, the open end of the tube 15 is located at the corner which contains air 14 thereby allowing the air 5 from outside the bottle 2 to combine with the air in the corner 14. Thus, from the beginning of use of the bottle 2, none of the liquid can flow out of the bottle through the tube 9. Only the small amount of the liquid which had already been within the tube when it was standing upright will now flow down to the top of the reservoir 23 and remain there, below the level of the air inlet hole/tube 12 allowing a free passage for incoming air.
The top of the reservoir 23 retains a small amount of liquid which is kept from leaking through the air inlet hole/tube 12. The top of the reservoir 23 is large enough to contain the entire amount of the liquid which had been located in the tube 9.
The lower part of the reservoir 13 should be as large as the top part of the reservoir 23 in order to contain the full amount of which will flow into it when flow is stopped, due to stoppage of drinking and holding the container upright. The liquid which was contained in the top part of the reservoir 23 will not leak outside the bottle through the air hole/tube 12 but rather will be contained in the bottom part of the reservoir 13 and then slowly continue flowing down through the tube 9 to the bottom of the bottle. The top 23 and the lower part 13 of the reservoir need be of equal size. This is accomplished by placing the air inlet hole/tube 12 in the exact middle of the reservoir 7. The present invention results in a steady strong fluid flow from a narrow neck inverted bottle, without a resulting gurgling and intermittent flow.
As shown in
We can summarize the inventions in other words as follows A bottle (2) with a mechanism for enabling a steady discharge of liquids (1) from the bottle when the bottle is in an inverted position. The mechanism includes.
The distance between the first opening of the horizontal tube and the inner wall of the reservoir makes it difficult for liquids in the reservoir that slide on the inner wall of the reservoir while the bottle is rotated to flow out through the first opening of the horizontal tube.
