[0037] Please refer to the following Figures 1 to 8 The specific structure of a stable tampon applicator protected by the present invention is described in detail.

[0038] Example 1

[0039] Reference Figures 1 to 6As shown, this embodiment provides a stable tampon applicator 100, including a sleeve 1 and a push rod 2 at least partially inserted into the sleeve 1. The push rod 2 and the sleeve 1 move relative to each other to push the tampon out. The tampon applicator 100 provided in this embodiment has an optimized structure, so that when the user pushes the push rod 2 to push the tampon into the body, the push of the push rod 2 is smooth and controllable, and the tampon has a smooth running path, which can effectively avoid the discomfort caused by the shaking of the tampon.

[0040] Wherein, the sleeve 1 includes a cavity 11 for accommodating the tampon and a hand-held portion 12 connected to one end of the cavity 11. The sleeve 1 also includes a discharge end 131 provided at its top end for discharging the tampon and an insertion end 132 provided at its tail end for inserting the push rod, and the insertion end 132 is connected to the hand-held portion 12. In this embodiment, the discharge end 12 is a round bullet head structure, so that the discharge end 12 has a streamlined structure, reducing the friction when entering the human body. The discharge end 12 is a petal structure, including a plurality of petals arranged adjacent to each other. When the molding is completed, the petals are in an open shape, and the tampon is loaded. After being heated and formed, the petals are gathered together, and the adjacent petals are movable and closed. In this way, the tampon can be effectively prevented from being contaminated before use, thereby improving the sterility of the tampon.

[0041] The handle 12 includes an elastic component 14 disposed on its inner side. The elastic component 14 forms a channel that cooperates with the push rod 2. The elastic component 14 includes a plurality of elastic members 16 arranged axially along the sleeve 1. Each elastic member 16 is at least partially movably engaged with the push rod 2. There are two or more elastic members 16, which are evenly disposed on the same circumferential surface. When the push rod 2 enters the cavity 11 through the channel, the provision of the elastic component 14 can provide axial support for the push rod 2, allowing the push rod 2 to move smoothly without circumferential shaking. It can also prevent circumferential shaking of the tampon when it is pushed into the body, thereby avoiding shaking of the tampon during the insertion process and causing discomfort to the user, thereby improving the user experience.

[0042] like Figure 4 As shown, in this embodiment, the elastic member 16 is a spring clip 17. The spring clip 17 includes a fixed end 18 and a free end 19. The spring clip 17 is disposed adjacent to each other along the inner side of the handle 12. The free end 19 extends toward the rear end of the sleeve 1, while the fixed end 19 is attached to the inner side of the handle 12. In a preferred embodiment, the fixed ends 19 of all spring clips 17 extend circumferentially and interconnect to form a ring structure, thereby improving the stability of the spring clip 17 and reducing the manufacturing difficulty.

[0043] The spring clip 17 is tilted relative to the centerline γ of the sleeve 1, and the free end 19 is arranged to converge toward the centerline γ of the sleeve 1. That is, the channel is configured as a variable diameter, with the end closest to the cavity 11 having a larger diameter and the end further away from the cavity 11 having a smaller diameter. As a preferred embodiment, the angle formed between the spring clip 17 and the centerline of the sleeve 1 is [15-60]°. The push rod 1 can be of constant diameter or a gradually varying diameter, with the end located inside the sleeve 1 having a larger diameter and the end located outside the sleeve 1 having a smaller diameter. The side of the push rod 2 is arranged in close contact with the spring clip 17. This provides a certain amount of friction during the withdrawal of the push rod 2, providing an effective positioning effect, preventing the user from accidentally releasing the push rod 2 during use and causing axial slippage. It also prevents the user from experiencing discomfort due to excessive thrust, which could cause the tampon to be pushed in too quickly, and prevents premature ejection of the tampon due to misoperation, which could affect its use. For ease of description, the push rod 2 in this embodiment is configured as a constant diameter.

[0044] As a preferred embodiment, the spring 17 further includes an engaging structure 20 disposed at the free end 19, which movably abuts against the push rod 2. The engaging structure 20 can be any other structure having an engaging function, such as a claw structure. The provision of the engaging structure 20 further enhances the engagement of the elastic component 14 with the sleeve 1, improving the operational smoothness and reliability of the push rod 2.

[0045] The handle 12 is a concave structure, and the fixed end 18 of the spring 17 is arranged on the inner side of the concave structure to form a limit portion 32 to prevent the push rod 2 from being pushed into the cavity 11 by mistake. As a preferred embodiment, the limit portion 32 is arranged at the vertex of the inner side of the concave structure. Because the cross section at the vertex has the smallest diameter, when the limit portion 32 is arranged here, the diameter of the cross section at the vertex is further reduced, thereby effectively preventing the push rod 2 from being pushed into the cavity 11 by mistake. Accordingly, Figure 6 As shown, the push rod 2 includes an outward-turned first trumpet-shaped structure 33 provided at one end thereof outside the sleeve. When the push rod 2 is pushed into the cavity 11, the first trumpet-shaped structure 33 is pressed against the limiting portion 32 to limit the push rod 2, further preventing the push rod 2 from being mistakenly pushed into the cavity 11, thereby improving the structural stability and safety of the tampon applicator.

[0046] In some embodiments, the handle 12 further includes a ridge group 50 disposed on its inner side. The ridge group 50 is located at the junction of the cavity 11 and the handle 12, and is located on one side of the elastic component 14. The ridge group 50 includes a plurality of evenly spaced ridges 51 extending axially along the sleeve 1. Because the handle 12 is concave, the ridges 51 also have a corresponding curvature. Similar to the elastic component 14, the ridge group 50 also flexibly cooperates with the push rod 2, providing support for the push rod 2. A second trumpet-shaped structure 35 is provided at the other end of the push rod 2. The cross-sectional diameter of the second trumpet-shaped structure 35 is larger than that of the first trumpet-shaped structure 33 and larger than the diameter of the channel formed by the ridge group 50. This allows the first trumpet-shaped structure 33 to pass through the handle 12 during assembly, while the second trumpet-shaped structure 35 cannot, achieving the desired connection between the push rod 2 and the sleeve 1, while ensuring that the push rod 2 is at least partially located within the sleeve 1.

[0047] In some embodiments, the handle 12 includes an anti-slip layer 34 disposed on its surface. The anti-slip layer 34 is a silicone convex structure or a silicone coating with a hollow structure. The provision of the silicone anti-slip layer 34 increases the surface roughness of the handle 12, thereby preventing the user from slipping during use, resulting in a loose grip and dropping the push rod 2, or being unable to push the push rod 2 due to slipping, further improving user reliability. In some embodiments, to enhance aesthetics or symbolism, the silicone convex surface or hollow structure can be a flower-shaped or logo-shaped structure.

[0048] The spring piece 17 in this embodiment is made of PE, PVC, PP, PET or silicone, has certain elasticity and toughness, and has good bending and compression resistance to prevent loss of elasticity due to long-term non-use, thereby ensuring long-term effective cooperation between the elastic component 14 and the push rod 2.

[0049] Example 2

[0050] Reference Figure 7 This embodiment provides another stable tampon applicator 100. This tampon applicator 100 is similar in structure to the tampon applicator 100 in Example 1, differing only in that the spring element 17' is disposed parallel to the centerline of the sleeve 1, and the spring element 17' further includes a bent structure 41 at its free end 19', which movably abuts against the push rod 2. For the remaining structure of the tampon applicator 100, please refer to the detailed description in Example 1.

[0051] Specifically, the bending structure 41 includes a short side 42 perpendicular to the centerline of the sleeve 1 and a long side 43 connected at an angle to the short side 42, with the long side 42 tilted toward the centerline of the sleeve 1. Preferably, the angle formed between the long side 43 and the centerline of the sleeve 1 is [15-60] degrees. By providing the bending structure 41 at the free end of the spring piece 17', even when the push rod 2 is extended, the free end with the bending structure 41 can improve the fit with the sleeve 1, thereby enhancing the stability of the push rod 2 during its relative movement.

[0052] Example 3

[0053] Reference Figure 8 This embodiment provides another stable tampon applicator 100. The structure of the tampon applicator 100 is similar to that of the tampon applicator 100 in Example 1 or 2, with the only difference being that the elastic member 16 is a strip elastic body 17". The strip elastic body 17" is attached to the inner side of the hand-held portion 12 and includes a first end 51 closer to the cavity 11. The first end 51 is a sloped structure, and the strip elastic body 17" in this embodiment is made of silicone. For the remaining structure of the tampon applicator 100, please refer to the detailed description in Example 1 or 2.

[0054] Because the handle 12 is a concave structure, the strip elastic body 17" is arranged on its inner side surface, so it has the same curvature as the concave structure. As a preferred embodiment, the thickness of the strip elastic body 17" is 2 to 3 mm. In this case, the strip elastic body 17" cooperates better with the push rod 2. The first end 51 of the strip elastic body 17" that is closer to the cavity 11 is set to a slope structure, which facilitates the push rod 2 to pass through the sleeve 1 from the discharge end 12 for installation.

[0055] The tampon applicator in the above-mentioned embodiments 1 to 3 has an elastic component arranged on the inner side of the hand-held part. The elastic component supports the push rod, so that the relative movement of the push rod and the sleeve is relatively stable, the controllability is improved, and the tampon is prevented from circumferential shaking when being pushed into the body, thereby preventing the shaking of the tampon body during the pushing process and causing discomfort to the user, and the user experience is better; and the setting mode of the elastic component and the push rod is coordinated with each other, so that there is a certain friction force during the pulling process of the push rod, which plays a better positioning role, preventing the user from accidentally letting go during use and causing axial sliding of the push rod, and can prevent the user from feeling discomfort due to excessive thrust during use due to too fast pushing, and prevent the tampon from being pushed out prematurely due to misoperation and affecting use.

[0056] It should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
