WO2001070327A1 - A pneumatic tubal container opened by pressing its side - Google Patents

Abstract

The invention provides a pneumatic tubal container that is opened when its side wall is pressed. One end of said container is sealed while the other is opened and the container is equipped with a functional element. In the inner chamber between the two ends there is a separating device which can be easily opened, thus a sealing chamber is formed between said separating device and the sealing end. There are gas and working liquid in said sealing chamber. An opening element is sealed on the wall corresponding to said separating device. When the opening element is pressed, said separating device is opened at once. Therefore the liquid in said sealing chamber can be discharged quickly from the opening end under the gas pressure.

 Structural features and application methods of the present invention:

Please refer to FIGS. 1 to 23. Since the tubular container 10 and the easy-opening barrier device are homogeneous, the gas 50 and the working liquid 60 built into the sealed chamber of the tubular container are fixed after the sealed port 11 is fixedly closed. Closed for safe storage. Taking one of the embodiments as an example, when the opening element 30 is pressed from the side, since the longitudinal recessed wall surface 21 of the easy-opening blocking device is thin, it immediately breaks under the pressure of a sharp hard object, and the tubular container is opened. The working liquid 60 quickly flows out of the port 12 under the pressure of the gas 50. Since the easy-opening barrier device is provided in the concave portion of the pipe wall, the squeezing or collision of the tubular container will not cause the easy-opening barrier device to open, making it safer to store and use. According to different requirements, different functional elements may be provided at the open end portion 12 of the tubular container, as shown in Fig. 5, Fig. 6, Fig. 7, Fig. 8, and Fig. 9, which describe a part of them. When the functional element chooses to cover the cotton body 41 directly at the open end of the tubular container, in order to enable the working liquid 60 to be quickly and uniformly distributed in the cotton body 41, a longitudinal direction symmetrical to the axis may be opened on the pipe wall near the port. Bar-shaped through-holes, and plug the ports before covering the cotton body. The material of the cotton body 41 can be selected from natural cotton absorbers (such as cotton) or organic synthetic soft absorbers (such as sponges, etc.); the brush 44 can be selected from natural synthetic materials. Since the easy-opening barrier device may generate debris after being opened, the recessed through-hole 22 through which the working fluid flows after the tubular container is opened is to select several small holes to filter out possible debris. When the open end of the tubular container is When a functional element capable of retaining debris such as a cotton body 41 is connected to the part, a larger through hole may be selected as the through hole 22 on the concave inclined surface. In the second embodiment of the present invention, the flow rate and the flow rate of the working liquid can be controlled by adjusting the amplitude of pressing the opening element 30. The fifth embodiment can be used normally when the open end 12 of the tubular container is at an upward or any angle. Implement The sixth example satisfies the needs of single-carrying, long-term storage and standby, and the diameter of the sealed end portion 11 of the tubular container is increased to correspond to the sleeve-shaped cover 40. In the fifth embodiment and the sixth embodiment, the easy-open blocking device and the opening element can also choose the scheme adopted in other embodiments, and the effects are completely the same.

 When the diameter of the tubular container 10 is small, the tube wall corresponding to the easy-opening barrier device may be provided with an auxiliary protrusion 15 which is homogeneous with both sides and tangent to the wall surface of the tube wall, so as to facilitate the fastening of the opening element 30. seal. In addition, the convex wall on the longitudinal sides of the opening element 30 may be provided with convex portions or corresponding packaging materials, so as to solve the problem of pressing and misopening during storage and transportation which may be caused by the opening element protruding from the pipe wall. Such transformations as well as the transformation of the shape of the tubular container are within the scope of the present invention.

 Please refer to Figure 1 and Figure 7 to illustrate how to use it. Remove the hygienic packaging (such as a plastic film, a tubular cover, etc.), and hold the side-opened pneumatic tube 10 with one hand to hold the open end 12 connected to the functional element naturally downward, and use your thumb to remove When the opening element 30 is pressed laterally, the longitudinal recessed wall surface 21 of the easy-opening barrier device is changed from the state 21a to 21b, the tubular container is opened, and the working liquid 60 flows out from the open end 12 through the overflow under the pressure of the gas 50. The groove 43 quickly penetrates the cotton body 41, and the skin or wound can be applied.

 The invention is also applicable to the storage and use of working substances as gases.

 To sum up, the gas-pressure tubular container provided by the present invention with side-pressing opening, the gas and working liquid stored in the closed chamber are safely and reliably closed before use, and the open end can be Various functional elements need to be connected; when in use, just hold it with one hand and press the opening element on the side wall of the tubular container with your thumb, it will be opened immediately, and the medicinal solution, disinfectant, cosmetics and cleaning stored in the tubular container A working fluid such as an agent quickly flows out from the open end under the pressure of a gas, and can be used at any time. Its structure is simple, easy to use and natural, which overcomes the disadvantages of traditional products.
