Description

Technical Field

[0001] This utility model relates to the field of tampons, specifically to a polyethylene tampon applicator that prevents the push rod from falling off. Background Technology

[0002] As a daily necessity for women, the safety of tampons during use is paramount. To prevent the plunger from falling into the body and posing a risk, this application incorporates a one-way valve structure at the connection between the applicator and the tampon. This valve allows the tampon to be pushed out of the applicator while preventing the plunger from falling out. One end of the valve is connected to the inner wall of the applicator via a flexible polyethylene connector. When the tampon absorbs liquid and generates positive pressure, the valve opens, allowing the tampon to enter the body smoothly. When there is reverse pressure, the valve tightly adheres to the inner wall of the applicator, preventing the plunger from falling out and into the body. Utility Model Content

[0022] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure will not be enlarged to scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0024] This invention provides a polyethylene tampon applicator that prevents the pusher from falling out. Through a one-way valve structure, it only allows the tampon to be pushed out of the applicator, preventing the pusher from falling out. One end of the valve is connected to the inner wall of the applicator via a flexible polyethylene connecting strip. When the tampon absorbs liquid and generates positive pressure, the valve opens, allowing the tampon to smoothly enter the body. When there is reverse pressure, the valve tightly adheres to the inner wall of the applicator, preventing the pusher from falling out and into the body.

[0025] Figures 1-3 The diagram shown is a structural schematic of one embodiment of the polyethylene tampon applicator that prevents the push rod from falling off, according to this utility model. Please refer to [link / reference]. Figures 1-3 The present embodiment of a polyethylene tampon applicator for preventing the push rod from falling off includes a main body 100, a valve 200, and a push rod 300.

[0026] The tube 100 is convenient to hold with fingers via the grip 101. The flaps 102 prevent the tampon assembly from accidentally falling out of the tube 100. Specifically, the tube 100 contains the tampon assembly. In this embodiment, the grip 101 is provided at the inlet of the tube 100 and is trumpet-shaped. The flaps 102 are provided at the outlet of the tube 100 and have notches between them.

[0027] The valve 200 is connected to the inner wall of the tube 100 via a flexible polyethylene connecting strip 210, which has good elasticity. During the insertion of the tampon assembly, the tampon assembly absorbs water and expands, causing the valve 200 to be subjected to positive pressure and open, allowing the tampon assembly to enter the body smoothly. When the end of the tampon assembly completely detaches from the valve 200, the valve 200 closes under the reset action of the polyethylene connecting strip, blocking the push rod 300 and preventing it from falling into the body. Specifically, the valve 200 is located on the inner wall of the tube 100, and the opening of the valve 200 faces the inlet direction of the tube 100. In this embodiment, a flexible polyethylene connecting strip 210 is provided at the connection between the valve 200 and the inner wall of the tube 100. There are two valves 200, and a gap is provided between the two valves 200. The initial position of the front end of the tampon assembly is located between the gap.

[0028] The push rod 300 can stably push the tampon assembly into the body through the push plate 320. The pressing plate 310 facilitates finger pressure and, under the constraint of the trumpet-shaped grip part 101 of the tube body 100, further prevents the push rod 300 from entering the body. Specifically, the push rod 300 is pushed into the interior of the tube body 100 from the inlet. In this embodiment, the front end of the push rod 300 is provided with the push plate 320, and the rear end of the push rod 300 is provided with the pressing plate 310. The push rod 300 is a hollow tube, and the side walls of the push plate 320 and the pressing plate 310 are respectively provided with thread holes.

[0029] Combination Figures 1-3 This embodiment describes a polyethylene tampon applicator designed to prevent the push rod from falling out. The specific usage process is as follows: the grip 101 facilitates finger gripping; the valve 102 prevents the tampon assembly from accidentally falling out of the tube body 100; the flexible polyethylene connecting strip 210 serves as the connection medium to the inner wall of the tube body 100, possessing excellent elasticity. During insertion, the tampon assembly absorbs moisture and expands, causing the valve 200 to open under positive pressure, allowing the tampon assembly to smoothly enter the body. When the end of the tampon assembly completely detaches from the valve 200, the valve 200 closes under the repositioning action of the polyethylene connecting strip, blocking the push rod 300 and preventing it from falling into the body. The push plate 320 stably pushes the tampon assembly into the body; the pressing plate 310 facilitates finger pressure and, combined with the trumpet-shaped grip 101 of the tube body 100, further prevents the push rod 300 from entering the body.

[0030] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
