Description

Technical Field

[0001] This utility model relates to the field of hygiene products technology, specifically a three-section tube for sanitary napkin cores. Background Technology

[0002] A tampon insert is the absorbent material inside a sanitary tampon, primarily used to absorb menstrual blood. It is mainly made of cotton, synthetic fibers, or a mixture of both, and has a drawstring at the end. This material quickly absorbs secretions and blood, preventing body odor. There are various materials and designs for tampons, each with its own characteristics and applicable scenarios.

[0003] When inserting sanitary tampons into a user's vagina, a catheter is often needed for insertion. However, the existing catheters are quite long and inconvenient to carry.

[0004] Therefore, we propose to design a three-section tube for sanitary napkin cores. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of this section, the abstract, and the title, and such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0007] A three-section tube for sanitary napkin cores includes an outer tube, one end of which is threadedly connected to a top cap, and the other end of which is internally provided with a sleeve. A top rod is provided at the end of the sleeve away from the outer tube, and a cotton core is provided inside the outer tube. A connecting wire is fixedly connected to the end of the cotton core.

[0008] The push rod includes a push rod, with a positioning ring and an end block fixedly connected to each end of the push rod, and a protrusion fixedly connected to the outer wall of the end of the push rod near the positioning ring.

[0009] As a preferred embodiment of the three-section tube for sanitary napkin core described in this utility model, a first limiting ring and a second limiting ring are respectively fixedly connected to both ends of the inner wall of the tube. The first limiting ring is used to position the push rod inside the tube, and the second limiting ring is used to position the push rod outside the tube.

[0010] As a preferred embodiment of the three-section tube for sanitary napkins described in this utility model, the connecting line passes through the top rod and extends outward, so that the napkin can be easily pulled out after it is inserted into the user's vagina via the connecting line.

[0011] As a preferred embodiment of the three-section tube for sanitary napkins described in this utility model, a limiting tube is provided at one end of the outer tube near the top rod. When the user pushes the sleeve, the limiting tube can be squeezed to allow the sleeve to enter the outer tube, thereby facilitating the ejection of the sanitary napkin.

[0012] As a preferred embodiment of the three-section tube for sanitary napkin cores described in this utility model, the protrusions are provided in a plurality of shapes, which are evenly distributed in a ring on the outer wall of the push rod. The cross-section of the protrusions is triangular. When the user pulls the push rod out of the sleeve, the triangular protrusions limit the movement of the push rod, making it easier for the user to push the push rod and move the sleeve.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention utilizes the cooperation between the outer conduit, the sleeve, and the push rod to allow the push rod to be inserted into the sleeve for storage, greatly reducing the overall length of the push rod section. This facilitates the storage of the three-section tube consisting of the outer conduit, the sleeve, and the push rod, making it more convenient to carry. Attached Figure Description

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] 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 may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0022] 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.

[0023] Please see Figure 1-3 This utility model provides a three-section tube for sanitary napkin cores, including an outer tube 1, a top cover 2 threadedly connected to one end of the outer tube 1, a sleeve 3 disposed inside the other end of the outer tube 1, and a top rod 4 disposed inside the sleeve 3 at the end away from the outer tube 1.

[0024] The inner walls of the sleeve 3 are fixedly connected to a first limiting ring 301 and a second limiting ring 302 at both ends. The first limiting ring 301 is used to position the push rod 4 inside the sleeve 3, and the second limiting ring 302 is used to position the push rod 4 outside the sleeve 3.

[0025] The outer conduit 1 has a cotton core 5 inside, and a connecting wire 6 is fixedly connected to the end of the cotton core 5.

[0026] The connecting line 6 passes through the top rod 4 and extends outward. After the cotton core 5 is inserted into the user's vagina, the connecting line 6 facilitates the subsequent removal of the cotton core 5.

[0027] A limiting tube 7 is provided at one end of the outer guide tube 1 near the top rod 4. When the user pushes the sleeve 3, the limiting tube 7 can be squeezed to allow the sleeve 3 to enter the outer guide tube 1, thereby facilitating the ejection of the cotton core 5.

[0028] The push rod 4 includes a push rod 401, with a positioning ring 402 and an end block 403 fixedly connected to both ends of the push rod 401, and a protrusion 404 fixedly connected to the outer wall of the end of the push rod 401 near the positioning ring 402.

[0029] In this embodiment, a plurality of protrusions 404 are provided, and the plurality of protrusions 404 are evenly distributed in a ring on the outer wall of the push rod 401. The cross-section of the protrusions 404 is triangular. When the user pulls the push rod 4 out of the sleeve 3, the triangular protrusions 404 limit the user to push the push rod 4 and move the sleeve 3.

[0030] During installation, first insert the push rod 4 into the sleeve 3. The positioning ring 402 is limited by the first limiting ring 301, which positions the push rod 4, while the end of the push rod 4 near the end block 403 protrudes through. Then, insert the sleeve 3 together with the push rod 4 into the outer guide tube 1, so that the end of the sleeve 3 away from the end block 403 passes over the limiting tube 7 for positioning. Finally, insert the cotton core 5 into the outer guide tube 1.

[0031] In use, the top cover 2 of this device is petal-shaped. Pulling the end block 403 will pull the top rod 4 out of the sleeve 3 until the protrusion block 404 is pulled out of the sleeve 3. At this time, the positioning ring 402 is limited by the second limiting ring 302.

[0032] When the push rod 4 is pushed, the protrusion 404 restricts the push rod 4 so that the sleeve 3 can move into the outer catheter 1. After passing the restriction of the limiting tube 7, the cotton core 5 is pushed out of the petal-shaped top cover 2. The top cover 2 opens at the point where the petals break, so that the cotton core 5 can enter the vagina.

[0033] When storing the three-section tube, the push rod 4 is stored in the sleeve 3. Based on the original length of the push rod, the sleeve 3 and the push rod 4 are separated, reducing its storage length by half, making it easier to carry.

[0034] 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.
