TH12464C3 - Inner stopper with a reverse flow structure and a bottle cap that uses this inner cork. - Google Patents

Abstract

DC60 (29/10/56) This petty patent relates to an inner plug with a return structure. Which has a simple structure And it can solve the problem of the return of the liquid in some cases where the use of a non-return valve, meanwhile, this petty patent also provides a cap for bottles that use the cork inside. Where the inner cork is structured This patent petty return flow fits into the container opening. A number of guide discs connected Axially extended along the inner stopper is spaced on the inner wall of the inner stopper, with the top end of each guide plate connected by a curved surface plate. The counter-valves will be arranged in the enclosed chamber. By the aforementioned guide plates and curved surface plates The opening on the bottom of the inner plug shrinks inward along the back of the valve, thus creating a close coordination with the inner wall of the cavity. Open the bottom of the inner stopper under the action of gravity. A number of return openings are arranged. On the inner wall of the inner cup The return opening is spaced between the guide plates. Path and is above the intimately interlocking portion of the non-return valve and the lower opening of the inner plug in the longitudinal direction. With a reverse flow structure Which has a simple structure And it can solve the problem of liquid return in some cases where a counter valve is required. At the same time, this petty patent also provides a bottle cap that uses such an inner point. Where the inner point is structured This patent petty return flow fits into the container opening. A number of guide discs connected Expanded along the axis along the inner cork will Spaced on the inner wall of the inner point with the top end of the guide plate. Each plate, connected by a curved surface plate, is arranged in a chamber enclosed by the guide plate and the curved surface plate. Bottom opening Of the inner plug along the reverse axis, thus creating a close coordination with the inner wall of the cavity. Open the bottom of the inner stopper Where the opening flows back They will be spaced between the guides. Way and above the perfectly interlocking part of the piece with the back and the opening below the inner point in the longitudinal direction.

Claims (1)

1. Inner stopper (1) with return structure It fits in the container opening, with a number of guide plates (2) extending axially along the inner stopper. Spaced on the inner wall of the inner point (1), the top end of the guide plate (2), each of which is connected by a curved surface plate (3), a non-return valve (4), arranged in a room that surrounds The aforementioned guide plate (2) and the curved surface plate (3) the bottom opening of the inner plug (1) contracted inward along the counter-valve axis (4), thus creating a Closely coordinated with the inner wall of the bottom opening of the inner cork under the action of gravity, which is characterized by A number of return openings (5) are located on the inner wall of the inner stopper (1), where such return openings (5) are spaced between the guide plates (2) and above the interface. The tightening of the retaining valve and the opening below the inner plug in a longitudinal direction.
