Description

Technical Field

[0001] This application relates to the technical field of tampon applicators, specifically to a tampon applicator and a tampon applicator comprising the same. Background Technology

[0002] Tampons are cylindrical tampons made of cotton fibers, synthetic fibers, or a blend of both. They typically range in size from 1 cm to 1.9 cm and have a string at the end. Tampons are primarily used to absorb menstrual blood by being inserted into the vagina during menstruation. Applicator-type tampons come with a paper or plastic applicator for easy insertion.

[0003] Tampon applicator tampons come with a paper or plastic applicator for easy insertion. The tampon applicator consists of an outer tube and an inner tube. The outer tube has a smooth surface and a rounded tip for insertion. The tip of the outer tube usually has a petal-shaped opening to push the tampon out. The inner tube acts as a push rod, its main function being to push the tampon out of the petal-shaped opening of the outer tube in a piston-like manner.

[0004] Tampon applicator tampons have the following problems in actual production and use: First, during the production process, a tampon is placed inside the applicator. Due to differences in the structure of the applicator, the tampon inside the applicator may wobble during transportation. Second, due to poor fit between the applicator and the tampon, when the user pushes the plunger to push the tampon out of the applicator, the tampon may tilt or get stuck, resulting in the tampon not being able to be pushed out accurately and quickly, leading to a poor user experience. Summary of the Invention

[0005] To address at least one of the problems mentioned in the background art, this application provides a tampon applicator and a tampon applicator containing the applicator. When a tampon is inserted into the applicator, the applicator and the tampon can be precisely matched to ensure the stability of the tampon within the applicator. At the same time, the flat applicator design in this application makes it easier for users to pick up and control the applicator, and push the push rod to smoothly and quickly slide the tampon out of the applicator, greatly improving the user experience.

[0006] In a first aspect, a tampon applicator is provided, wherein a push rod is slidably inserted inside the hollow tampon applicator, the tampon applicator includes a bottom opening and a top opening, and a handle is provided at one end of the tampon applicator near the bottom opening. The handle is flat and hollow, and a receiving platform is provided on the inner wall of the handle. A receiving beam is connected to the upper end of the receiving platform. The receiving beam is inclined towards the central axis of the bottom opening and elastically fits against the outside of the push rod.

[0007] In one specific embodiment, at least two receiving beams are provided, and the two receiving beams are respectively provided on the two sides corresponding to the two ends of the long axis of the mid-section of the hand-held part, and the width of the receiving beams gradually narrows along the direction close to the bottom opening.

[0008] In one specific embodiment, the inner wall of the handheld part is further provided with limiting strips, and at least two limiting strips are provided, with the two limiting strips respectively provided on the two sides corresponding to the two ends of the short axis of the handheld part cross section.

[0009] In one specific embodiment, the inner wall of the handheld part is provided with a guide protrusion, one end of which is connected to the receiving platform and the other end extends into the tampon applicator.

[0010] In one specific embodiment, the height of the limiting strip gradually increases along the direction close to the bottom opening.

[0011] In one specific embodiment, the end of the guide strip extending into the tampon applicator is chamfered.

[0012] In one specific embodiment, the length ratio of the handle to the tampon applicator is in the range of 0.2 to 0.5:1, and the length ratio of the receiving beam to the handle is in the range of 0.2 to 0.4:1.

[0013] In one specific embodiment, the coefficient of friction of the outer surface of the handheld part is greater than the coefficient of friction of the outer surface of the tampon applicator.

[0014] In one specific embodiment, the ratio of the major axis to the minor axis length in the cross-section of the handheld part is in the range of 1 to 1.5: 0.2 to 0.8.

[0015] In one specific embodiment, the ratio of the length of the short axis of the handheld part to the diameter of the tampon applicator cross-section is in the range of 0.3 to 0.7:1.

[0031] In this application embodiment, "upper" and "lower" are both used in the sense of "upper" and "lower". Figure 1 and Figure 3 The orientation shown is the reference.

[0032] Example 1

[0033] A tampon applicator 1, such as Figure 1 and 2As shown, the tampon applicator 1 is a hollow cylindrical tube with openings at both ends. A push rod 11 slides through the tampon applicator 1. The push rod 11 is hollow and cylindrical, and flanges are fixedly connected to both ends of the push rod 11. The flanges are integrally formed with the push rod 11. The tampon applicator 1 has a bottom opening 2 and a top opening 3 at both ends, respectively. The top opening 3 is petal-shaped and used to push out the tampon inside the tampon applicator 1. A handle 4 is provided at the end of the tampon applicator 1 near the bottom opening 2. The connection between the tampon applicator 1 and the handle 4 is chamfered. The handle 4 is flat and hollow. Two receiving platforms 5 are provided on the inner wall of the handle 4. The two receiving platforms 5 are vertically fixed to the inner side wall of the handle 4, and the two receiving platforms 5 are correspondingly connected to the two sides at both ends of the long axis of the handle 4 cross section.

[0034] Furthermore, such as Figures 2-3 A receiving beam 6 is fixedly connected to the upper end of the receiving platform 5. The receiving beam 6 is inclined towards the central axis of the cross-section of the bottom opening 2 of the tampon applicator 1, so that the receiving beams 6 on both sides elastically abut against the outside of the push rod 11, forming a limit on the push rod 11. When the push rod 11 is inserted into the tampon applicator 1, as the push rod 11 pushes the tampon out of the top opening 3 of the tampon applicator 1, the receiving beam 6 elastically abuts against the outside of the push rod 11, ensuring that the push rod 11 smoothly pushes out the tampon. Moreover, based on the presence of the receiving beam 6, when the push rod 11 is not pushing the tampon, it is tightly abutted by the receiving beam 6, ensuring the positional stability of the push rod 11 and preventing the tampon from falling out due to shaking during transportation.

[0035] In one specific embodiment, to prevent the push rod 11 from deflecting during extension and retraction within the tampon applicator 1, a limiting strip 7 is fixedly connected to the inner wall of the handle 4. The length direction of the limiting strip 7 is parallel to the central axis of the tampon applicator 1. Two limiting strips 7 are provided, with each limiting strip 7 corresponding to one of the two sides of the short axis of the handle 4 cross-section. The height of the limiting strip 7 gradually increases towards the bottom opening 2 of the tampon applicator 1, so that when the tampon is not pushed out from the top of the tampon applicator 1, the flange at the end of the push rod 11 abuts against the bottom opening 2 of the tampon applicator 1. At this time, the limiting strips 7 on both sides and the supporting beam 6 abut against the outside of the push rod 11, thereby forming a stable positioning of the push rod 11.

[0036] A guide strip 8 is also provided on the inner wall of the handle part 4. Specifically, the guide strip 8 is integrally formed with the tampon applicator 1. The length direction of the guide strip 8 extends along the central axis of the tampon applicator 1. One end of the guide strip 8 is fixedly connected to the receiving platform 5. The guide strip 8 is connected to the side of the receiving platform 5 away from the receiving beam 6, and the other end of the guide strip 8 extends into the tampon applicator 1. After the push rod 11 is assembled into the tampon applicator 1 during the tampon production process, the guide strip 8 guides the push rod 11 to enter the tampon applicator 1 stably. This further enables the push rod 11 and the tampon applicator 1 to fit more tightly and stably. After the tampon is formed, the axial and radial shaking of the push rod 11 relative to the tampon applicator 1 is reduced. During the use of the tampon, the consumer can push the push rod 11 to push the tampon out of the tampon applicator 1. The guide protrusion 8 is located at the connection between the tampon applicator 1 and the handheld part 4 and is beveled. The beveled design can guide the extension and retraction of the push rod 11 within the tampon applicator 1 and control its stability.

[0037] The cross-section of the handle portion 4 is approximately elliptical, with the ratio of its major axis to its minor axis being 1:0.5. Specifically, when the major axis of the handle portion 4 is 1 cm, the corresponding minor axis is 0.5 cm. In one specific embodiment, the ratio of the minor axis of the handle portion 4 to the diameter of the tampon applicator 1 is 0.4:1. The tampon applicator 1 has a circular cross-section; that is, when the diameter of the circular cross-section of the tampon applicator 1 is 1 cm, the corresponding minor axis of the handle portion 4 is 0.4 cm.

[0038] In one specific embodiment, to facilitate the user in picking up the tampon applicator 1 and stably pushing the push rod 11, it is necessary to reasonably set the ratio of the length of the handle 4 to the length of the tampon applicator 1. This determines an optimal position that allows the entire tampon applicator 1 to remain balanced when the handle 4 is picked up. Accordingly, the length ratio of the handle 4 to the tampon applicator 1 is set to a range of 0.3:1, and the length ratio of the support beam 6 on the inner wall of the handle 4 to the handle 4 is also set to a range of 0.3:1. Specifically, with the above ratio settings, for example, when the size of the tampon applicator 1 is 7 cm, the corresponding length of the handle 4 is 2.1 cm, and the length of the support beam 6 on the inner wall of the handle 4 is 0.63 cm.

[0039] In one specific embodiment, to facilitate the user's easier process of picking up the handle 4 and adjusting the push rod 11 to push out the tampon, the coefficient of friction of the outer surface of the handle 4 is set to be greater than the coefficient of friction of the outer surface of the tampon applicator 1, and the area with a high coefficient of friction on the outer surface of the tampon applicator 1 extends to the bottom of the petal-shaped opening 3 at the top of the tampon applicator 1. Because the coefficients of friction of the handle 4 and the outer surface of the tampon applicator 1 are different, and because the outer surfaces of the handle 4 and the tampon applicator 1 also have visual differences, the RGB value of the handle 4 is lower than the RGB value of the outer surface of the tampon applicator 1.

[0040] In a specific embodiment, such as Figure 4 and 5 As shown, the wall thickness of the tampon applicator 1 is gradually decreasing, specifically, the wall thickness of the tampon applicator 1 gradually thins from the bottom opening 2 to the top opening 3. Because the structure of the tampon applicator 1 is unstable and easily deformed during processing, a thicker wall near the bottom opening 2 increases the stability of the tampon applicator 1, allowing the push rod 11 to be stably assembled into the tampon applicator 1. Simultaneously, making the wall thickness thinner at the end of the tampon applicator 1 near the top opening 3 makes it easier for the user to push the push rod 11 to slide the tampon out of the top opening 3.

[0041] Furthermore, the push rod 11 is a hollow cylinder with a gradually changing diameter. The two ends of the push rod 11 are respectively provided with a first flared opening and a second flared opening, with different diameters. Specifically, the first flared opening corresponds to the end of the push rod 11 with a smaller diameter, and the second flared opening corresponds to the end of the push rod 11 with a larger diameter. During the assembly of the push rod 11 and the tampon applicator 1, the smaller diameter end of the push rod 11 is inserted along the top opening 3 of the tampon applicator 1. As the push rod 11 is inserted deeper into the tampon applicator 1, the gap between the push rod 11 and the tampon applicator 1 becomes smaller, resulting in a tighter fit between the push rod 11 and the tampon applicator 1. This reduces the likelihood of wobbling when the tampon is placed in the tampon applicator 1 or when the push rod 11 pushes out the tampon.

[0042] In one specific embodiment, the top opening 3 of the tampon applicator 1 is configured as a petal shape, that is, the top opening 3 of the tampon applicator 1 is provided with petal blades 9, wherein five petal blades 9 are evenly distributed along the circumference of the tampon applicator 1, and a reserved gap 10 is provided between two adjacent petal blades 9.

[0043] Specific implementation process: The tampon applicator 1 includes a tampon tube 1, a push rod 11 inserted inside the tampon tube 1, and a tampon placed inside the tampon tube 1. The tampon tube 1 is a hollow cylindrical shape and includes a bottom opening 2 and a top opening 3. The push rod 11 is used to push the tampon out of the top opening 3 of the tampon tube 1. The inner wall of the handle 4 is provided with a receiving beam 6, a limiting strip 7, and a limiting protrusion. When the tampon is placed inside the tampon tube 1, the push rod 11 needs to extend from the bottom opening 2 of the tampon tube 1 to the flange position at the end of the push rod 11. The outer flange of the push rod 11 elastically abuts against the receiving beams 6 on both sides, while the other two sides of the flange of the push rod 11 are in close contact with the limiting strip 7. Through the cooperation of these two, the push rod 11 is stably stopped in the extended state. When it is necessary to push the tampon out of the tampon tube 1... When the top opening 3 is pushed out, the user picks up the handle 4 and inserts it to the appropriate angle, and then pushes the push rod 11 to push the tampon out from the top opening 3 of the tampon applicator 1. During this process, the receiving beam 6 and the limiting strip 7 can elastically abut against both sides of the push rod 11 to limit the push rod 11. At the same time, the guide protrusion 8 guides the extension and retraction of the push rod 11, further ensuring that the push rod 11 extends and retracts smoothly and quickly in the tampon applicator 1, so as to achieve precise matching between the applicator and the tampon and ensure the stability of the tampon in the applicator.

[0044] Example 2

[0045] Corresponding to the above embodiments, this application provides a tampon applicator 1. The tampon applicator 1 is a hollow cylindrical applicator with openings at both ends. A push rod 11 is slidably inserted inside the tampon applicator 1. The push rod 11 is hollow and cylindrical, and flanges are fixedly connected to both ends of the push rod 11. The flanges are integrally formed with the push rod 11. The two ends of the tampon applicator 1 are respectively provided with a bottom opening 2 and a top opening 3, wherein the top opening 3 is petal-shaped and used to push out the tampon inside the tampon applicator 1. A handle 4 is provided at one end of the tampon applicator 1 near the bottom opening 2. The connection between the tampon applicator 1 and the handle 4 is chamfered. The handle 4 is flat and hollow. Two receiving platforms 5 are provided on the inner wall of the handle 4. The two receiving platforms 5 are vertically fixedly connected to the inner side wall of the handle 4, and the two receiving platforms 5 are correspondingly connected to the two sides at both ends of the long axis of the handle 4 cross section.

[0046] The difference between this embodiment and Embodiment 1 is that the cross-section of the handle 4 is approximately elliptical, wherein the ratio of the length of the major axis to the minor axis of the cross-section of the handle 4 is 1:0.4. Specifically, when the length of the major axis of the cross-section of the handle 4 is 1 cm, the corresponding length of the minor axis is 0.4 cm. In a specific embodiment, the ratio of the length of the minor axis of the cross-section of the handle 4 to the diameter of the tampon applicator 1 is 0.3:1, and the cross-section of the tampon applicator 1 is circular. That is, when the diameter of the circular cross-section of the tampon applicator 1 is 1 cm, the corresponding length of the minor axis of the cross-section of the handle 4 is 0.3 cm.

[0047] In one specific embodiment, to facilitate the user in picking up the tampon applicator 1 and stably pushing the push rod 11, it is necessary to reasonably set the ratio of the length of the handle 4 to the length of the tampon applicator 1. This determines an optimal position that allows the entire tampon applicator 1 to remain balanced when the handle 4 is picked up. Accordingly, the length ratio of the handle 4 to the tampon applicator 1 is set to a range of 0.4:1, and the length ratio of the support beam 6 on the inner wall of the handle 4 to the handle 4 is also set to a range of 0.4:1. Specifically, with the above ratio settings, for example, when the size of the tampon applicator 1 is 7 cm, the corresponding length of the handle 4 is 2.8 cm, and the length of the support beam 6 on the inner wall of the handle 4 is 1.12 cm.

[0048] In one specific embodiment, the top opening 3 of the tampon applicator 1 is provided with a petal-shaped opening, specifically including at least three petal blades 9. In this embodiment, five petal blades 9 are provided, and a reserved gap 10 is provided between two adjacent petal blades 9. Specifically, the width of the reserved gap 10 is set to 0.1-0.5 cm, and the ratio of the length of the petal blades 9 to the length of the tampon applicator 1 is 0.3-0.4:1. Specifically, in this embodiment, the ratio of the length of the petal blades 9 to the length of the tampon applicator 1 is 0.35:1. For example, when the length of the tampon applicator 1 is 8 cm, the length of the petal blades 9 is 2.8 cm.

[0049] With the support beam 6, support platform 5, and limiting strip 7 inside the tampon applicator 1, when it is necessary to push the tampon out of the top opening 3 of the tampon applicator 1, the user picks up the handle 4 and inserts it at a suitable angle, and then pushes the push rod 11 to push the tampon out of the top opening 3 of the tampon applicator 1. During this process, the support beam 6 and the limiting strip 7 can elastically abut against both sides of the push rod 11 to limit the push rod 11, and at the same time, the guide protrusion 8 guides the extension and retraction of the push rod 11. Furthermore, with the setting of the petal opening, when the tampon is not pushed, the petal blades 9 can form a barrier at the top opening 3 of the tampon applicator 1, restricting the tampon inside the tampon applicator 1 and preventing it from vibrating and falling out. Moreover, when the push rod 11 is pushed, the tampon can be pushed out of the opening of the petal blades 9 under a certain pushing force.

[0050] Example 3

[0051] Corresponding to the above embodiments, this application provides a tampon applicator, including a tampon tube and a push rod 11 slidably inserted into the tampon tube 1, the push rod 11 being used to push the tampon out of the tampon tube.

[0052] Specifically, the push rod 11 has a gradually decreasing diameter cylindrical shape, and flanges are fixedly connected to both ends of the push rod 11. The push rod 11 gradually widens along the direction close to the bottom opening 2 of the tampon applicator 1. When the tampon is inserted into the tampon applicator 1, the widest part of the push rod 11 mates with the bottom opening 2 of the tampon applicator 1, thus allowing one tampon to be inserted into the cavity of the tampon applicator 1.

[0053] In one specific embodiment, the tampon applicator 1 is a hollow cylinder. The two ends of the tampon applicator 1 are respectively provided with a bottom opening 2 and a top opening 3. The top opening 3 is designed as a petal shape and is composed of multiple petal blades 9. Specifically, in this embodiment, there are five petal blades 9. The end of the tampon applicator 1 near the bottom opening 2 is provided with a handle 4. The connection between the tampon applicator 1 and the handle 4 is chamfered. The handle 4 is flat and hollow. The inner wall of the handle 4 is provided with two receiving platforms 5. The two receiving platforms 5 are vertically fixedly connected to the inner side wall of the handle 4, and the two receiving platforms 5 are correspondingly connected to the two sides at both ends of the long axis of the handle 4 cross section.

[0054] Furthermore, a receiving beam 6 is fixedly connected to the upper end of the receiving platform 5. The receiving beam 6 is inclined towards the central axis of the cross-section of the bottom opening 2 of the tampon applicator 1, so that the receiving beams 6 on both sides elastically abut against the outside of the push rod 11, forming a limit on the push rod 11. When the push rod 11 is inserted into the tampon applicator 1, as the push rod 11 pushes the tampon out from the top opening 3 of the tampon applicator 1, the receiving beam 6 elastically abuts against the outside of the push rod 11, ensuring that the push rod 11 smoothly pushes out the tampon. Moreover, based on the presence of the receiving beam 6, when the push rod 11 is not pushing the tampon, it is tightly abutted by the receiving beam 6, ensuring the positional stability of the push rod 11 and preventing the tampon from falling out during transportation due to shaking.

[0055] To prevent the push rod 11 from deflecting during extension and retraction within the tampon applicator 1, a limiting strip 7 is fixedly connected to the inner wall of the handle 4. The length direction of the limiting strip 7 is parallel to the central axis of the tampon applicator 1. The limiting strip 7 has two sections, which are respectively positioned on the two sides corresponding to the ends of the short axis of the handle 4 cross section. The height of the limiting strip 7 gradually increases towards the bottom opening 2 of the tampon applicator 1, so that when the tampon is not pushed out from the top of the tampon applicator 1, the flange at the end of the push rod 11 abuts against the bottom opening 2 of the tampon applicator 1. At this time, the limiting strips 7 on both sides and the supporting beam 6 abut against the outside of the push rod 11, thereby forming a stable positioning of the push rod 11.

[0056] A guide strip 8 is also provided on the inner wall of the handle part 4. Specifically, the guide strip 8 is integrally formed with the tampon applicator 1. The length direction of the guide strip 8 extends along the central axis of the tampon applicator 1. One end of the guide strip 8 is fixedly connected to the receiving platform 5. The number of guide strips 8 and receiving platforms 5 corresponds one-to-one. The guide strip 8 is connected to the side of the receiving platform 5 away from the receiving beam 6, and the other end of the guide strip 8 extends into the tampon applicator 1. The guide strip 8 is chamfered at the connection between the tampon applicator 1 and the handle part 4. The chamfering can guide the extension and retraction of the push rod 11 in the tampon applicator 1 and control its stability.

[0057] In one specific embodiment, the cross-section of the handle portion 4 is approximately elliptical, wherein the ratio of the length of the major axis to the length of the minor axis in the cross-section of the handle portion 4 is 1:0.5. Specifically, when the length of the major axis of the cross-section of the handle portion 4 is 1 cm, the corresponding length of the minor axis is 0.5 cm. In another specific embodiment, the ratio of the length of the minor axis of the cross-section of the handle portion 4 to the diameter of the tampon applicator 1 is 0.4:1. The cross-section of the tampon applicator 1 is circular; that is, when the diameter of the circular cross-section of the tampon applicator 1 is 1 cm, the corresponding length of the minor axis of the cross-section of the handle portion 4 is 0.4 cm.

[0058] In one specific embodiment, to facilitate the user in picking up the tampon applicator 1 and stably pushing the push rod 11, it is necessary to reasonably set the ratio of the length of the handle 4 to the length of the tampon applicator 1. This determines an optimal position that allows the entire tampon applicator 1 to remain balanced when the handle 4 is picked up. Accordingly, the length ratio of the handle 4 to the tampon applicator 1 is set to a range of 0.3:1, and the length ratio of the support beam 6 on the inner wall of the handle 4 to the handle 4 is also set to a range of 0.3:1. Specifically, with the above ratio settings, for example, when the size of the tampon applicator 1 is 7 cm, the corresponding length of the handle 4 is 2.1 cm, and the length of the support beam 6 on the inner wall of the handle 4 is 0.63 cm.

[0059] In one specific embodiment, to facilitate the user's easier process of picking up the handle 4 and adjusting the push rod 11 to push out the tampon, the coefficient of friction of the outer surface of the handle 4 is set to be greater than the coefficient of friction of the outer surface of the tampon applicator 1, and the area with a high coefficient of friction on the outer surface of the tampon applicator 1 extends to the bottom of the petal-shaped opening 3 at the top of the tampon applicator 1. Because the coefficients of friction of the handle 4 and the outer surface of the tampon applicator 1 are different, and because the outer surfaces of the handle 4 and the tampon applicator 1 also have visual differences, the RGB value of the handle 4 is lower than the RGB value of the outer surface of the tampon applicator 1.

[0060] In one specific embodiment, the top opening 3 of the tampon applicator 1 is petal-shaped, meaning that the top opening 3 of the tampon applicator 1 has petal blades 9, wherein five petal blades 9 are evenly distributed along the circumference of the tampon applicator 1, and a reserved gap 10 is provided between two adjacent petal blades 9. Specifically, the top opening 3 of the tampon applicator 1 has a petal-shaped opening, including at least three petal blades 9. In this embodiment, five petal blades 9 are provided, and a reserved gap 10 is provided between two adjacent petal blades 9. Specifically, the width of the reserved gap 10 is set to 0.1 cm. In this embodiment, the ratio of the length of the petal blades 9 to the length of the tampon applicator 1 is 0.35:1. For example, when the length of the tampon applicator 1 is 8 cm, the length of the petal blades 9 is 2.8 cm.

[0061] The above description is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
