Description

Technical Field

[0001] This application relates to the field of packaging structure technology, and in particular to a hose structure. Background Technology

[0002] Packaging tubes have become one of the main packaging varieties for cosmetics, pharmaceuticals and food due to their convenience, economy and good hygiene.

[0003] Some packaging tubes used in cosmetics use soft rubber materials at the end that comes into contact with the user's skin to provide a soft touch. However, when the soft rubber material is fixedly connected to the tube, it cannot be used if the soft rubber material is damaged or becomes dirty. On the other hand, the usual detachable connection method makes it easy for the soft rubber material to fall off during use because it cannot remain stable. Summary of the Invention

[0004] To address the aforementioned problems, this application provides a flexible hose structure.

[0005] The flexible hose structure provided in this application adopts the following technical solution: A flexible hose structure includes a tube body, a cap, a threaded connector, and a flexible rubber head. The threaded connector is installed at one end of the tube body and has an external thread on its outer wall. The inner wall of the cap has an internal thread, and the cap is threaded to the tube body through the internal and external threads. The threaded connector has an annular groove for the flexible rubber head to be inserted. The flexible rubber head includes a connecting ring and a fixing part. The thickness of the connecting ring is less than the thickness of the fixing part. The connecting ring is connected along the center line of the wall thickness of the fixing part, so that at the connection point between the connecting ring and the fixing part, both sides of the connecting ring have the wall thickness of the fixing part. The connecting ring is inserted into the annular groove, so that the outer and inner walls of the connecting ring fit against the annular groove, and the bottom wall thickness of the fixing part fits against the top of the threaded connector.

[0006] By adopting the above technical solution, the tube body and the cover body are disassembled and assembled through a threaded connector, allowing the material inside the tube body to be stored. When the cover body is opened, the material is delivered to the soft rubber head through the threaded connector, and the soft rubber head delivers the material out of the tube body. At the same time, the soft rubber head comes into contact with the user's skin to spread the material evenly on the skin. In order to ensure that the soft rubber head does not separate from the threaded connector body during application, a connecting ring is inserted into the annular groove. The inner and outer walls of the connecting ring abut against the inner wall of the annular groove, and the wall thickness at the bottom of the fixing part abuts against the top wall of the threaded connector body, so as to achieve fixation of multiple contact surfaces, thereby increasing the overall friction area and maintaining the stable connection of the soft rubber head.

[0007] Optionally, the fixing part consists of a contact end and an annular end. The contact end has a discharge port for pouring out the inner material. The annular end is connected to the connecting ring and has reserved wall thickness on the inner and outer sides, fitting against the top of the screw pipe head.

[0008] By adopting the above technical solution, the inner material is poured out from the outlet simultaneously through the contact end in contact with the user's skin. The wiping of the contact end allows the inner material to be evenly applied. The annular end is used to connect with the connecting ring, and sufficient wall thickness is reserved on the inner and outer sides to ensure that both sides fit the screw head and ensure the stability of the soft rubber head connection.

[0009] Optionally, the end of the contact end with the discharge port has an irregular surface.

[0010] By adopting the above technical solution, the irregular surface increases the contact area with the user's skin, thereby increasing the application range. For example, after the material is poured out from the outlet, the irregular surface can increase the application area, thus improving the comfort of use.

[0011] Optionally, the inner wall of the annular groove is provided with a wavy groove, and the connecting ring wall surface opposite to the wavy groove is provided with a staggered wavy groove.

[0012] By adopting the above technical solution, the function of the wavy groove is to provide a limiting snap-fit ​​effect. The staggered wavy grooves of the two achieve a staggered snap-fit ​​effect, thereby increasing the tightness when the connecting ring and the annular groove are inserted.

[0013] Optionally, based on the irregular surface of the contact end, the contact end is divided into a high side and a low side, and a first anti-bending piece is provided at the top of the screw head corresponding to the high side where it fits against the outer wall of the contact end.

[0014] By adopting the above technical solution, when the user presses the contact end with force, the irregular surface provides guidance, causing the contact end to bend in the direction of the first anti-bending piece. Therefore, the first anti-bending piece is used to resist the bending direction of the contact end, thereby preventing the contact end from bending and improving the stability of the soft rubber head.

[0015] Optionally, a second anti-bending tab is provided at the top of the screw connector corresponding to the lower side where it fits against the inner wall of the contact end.

[0016] By adopting the above technical solution, the first anti-bending piece abuts against the outer wall of the contact end, while the second anti-bending piece abuts against the inner wall of the contact end, thereby achieving two-point contact and further increasing the anti-bending effect.

[0017] Optionally, both the first and second anti-bending sheets are semi-circular sheet structures.

[0018] By adopting the above technical solution, the semi-circular sheet structure can reduce the area required for materials. At the same time, the semi-circular sheet structure has a more stable bonding effect and will not produce sharp corners or other issues that would affect the user experience.

[0019] Optionally, both the first and second anti-bending sheets have the wavy grooves on their contact surfaces with the contact ends, and the opposite contact ends have staggered wavy grooves.

[0020] By adopting the above technical solution, the two staggered wavy grooves can increase the friction between the contact end and the first and second anti-bending pieces, so that the first and second anti-bending pieces can reduce slippage or misalignment of forces when providing anti-bending.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. The tube body and the cover body are connected and disconnected via a threaded connector, allowing the material inside the tube body to be stored. When the cover body is opened, the material inside the tube body is delivered to the soft rubber head through the threaded connector, and the soft rubber head delivers the material out of the tube body. At the same time, the soft rubber head comes into contact with the user's skin to spread the material evenly on the skin. In order to ensure that the soft rubber head does not separate from the threaded connector body during application, a connecting ring is inserted into the annular groove. The inner and outer walls of the connecting ring abut against the inner wall of the annular groove, and the wall thickness at the bottom of the fixing part abuts against the top wall of the threaded connector body, so as to achieve fixation of multiple contact surfaces, thereby increasing the overall friction area and maintaining a stable connection of the soft rubber head. 2. The inner material is poured out from the outlet simultaneously through the contact end to contact the user's skin. The inner material can be evenly spread by wiping with the contact end. The annular end is used to connect with the connecting ring, and sufficient wall thickness is reserved on the inner and outer sides to ensure that both sides fit with the screw head and ensure the firm connection of the soft rubber head. 3. The irregular surface increases the contact area with the user's skin, thus increasing the application area. For example, after the material is poured out from the outlet, the irregular surface can increase the application area, improving the comfort of use. 4. The purpose of the wavy groove is to provide a limiting snap-fit ​​effect. The staggered wavy grooves of the two achieve a misaligned snap-fit ​​effect, thereby increasing the tightness when the connecting ring and the annular groove are inserted.

[0028] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 This application will be described in further detail below.

[0029] This application discloses a hose structure.

[0030] A flexible tube structure, reference Figure 1 and Figure 2 As shown, it includes a tube body 1, a cover body 2, a screw-in connector 3, and a soft rubber head 4; the tube body 1 contains liquid material, which is liquid cosmetic, and is referred to here as the material.

[0031] The threaded connector 3 is installed at one end of the pipe body 1. The outer wall of the connector 3 has an external thread, and the inner wall of the cover 2 has an internal thread. The cover 2 is screwed to the pipe body 1 through the internal and external threads. The size of the threaded connector 3 is smaller than the size of the pipe body 1, or the outer diameter of the threaded connector 3 is smaller than the outer diameter of the pipe body 1, so that the cover 2 can cover the threaded connector 3 to achieve the effect of screwing. At the same time, the cover 2 can cover the threaded connector 3 so that it cannot be seen from the outside, ensuring the aesthetic appearance of the overall appearance.

[0032] The screw connector 3 has an annular groove 31 for inserting the soft rubber head 4. The soft rubber head 4 is a structure that is in direct contact with the user's skin. When applied to the user's skin, the soft rubber head 4 can directly contact the user's skin. Its soft rubber material can better match the user's touch, making the user's contact more comfortable. The insertion of the soft rubber head 4 into the annular groove 31 ensures the stable installation of the soft rubber head 4.

[0033] refer to Figure 2 and Figure 3 As shown, the soft rubber head 4 includes a connecting ring 41 and a fixing part 42; the connecting part is used to connect with the screw-in connector 3, while the fixing part 42 is used to contact the user's skin. The thickness of the connecting ring 41 is less than the thickness of the fixing part 42. The connecting ring 41 is connected along the center line of the wall thickness of the fixing part 42, so that at the connection point between the connecting ring 41 and the fixing part 42, the wall thickness of the fixing part 42 is left on both sides of the connecting ring 41.

[0034] The connecting ring 41 is inserted into the annular groove 31, so that the outer and inner walls of the connecting ring 41 are in contact with the annular groove 31, and the bottom wall thickness of the fixing part 42 is in contact with the top of the threaded pipe head 3, thereby achieving multiple contact surfaces. The soft rubber material used in the soft rubber head 4 itself generates a large friction with the groove wall of the annular groove 31. By using multiple contact surfaces to increase the friction area, a stable connection effect is obtained after the connecting ring 41 is inserted into the annular groove 31.

[0035] Specifically, the tube body 1 and the cover body 2 are connected and disconnected via a threaded connector 3, allowing the material inside the tube body 1 to be stored. When the cover body 2 is opened, the material is conveyed to the soft rubber head 4 through the threaded connector 3, and the soft rubber head 4 conveys the material out of the tube body 1. At the same time, the soft rubber head 4 comes into contact with the user's skin to spread the material evenly on the skin. To ensure that the soft rubber head 4 does not separate from the threaded connector body 1 during application, a connecting ring 41 is inserted into the annular groove 31. The inner and outer walls of the connecting ring 41 abut against the inner wall of the annular groove 31, and the bottom wall thickness of the fixing part 42 abuts against the top wall of the threaded connector 3, thereby achieving multiple contact surfaces for fixation, thereby increasing the overall friction area and maintaining a stable connection of the soft rubber head 4. When it is necessary to replace the soft rubber head 4, a force greater than the friction force is applied to the soft rubber head 4 to separate the connecting ring 41 from the annular groove 31.

[0036] Further reference Figure 4 As shown, the fixing part 42 is divided into a contact end 421 and an annular end 422. The contact end 421 has a discharge port 44 for pouring out the inner material. The contact end 421 is the end that comes into contact with the user's skin. The annular end 422 is connected to the connecting ring 41 and fits against the top of the screw-in connector 3. The annular end 422 is the end that is connected to the connecting ring 41. The thickness of the annular end 422 is greater than the thickness of the connecting ring 41. The connecting ring 41 is arranged along the circumference of the annular end 422, and the wall thickness side of the connecting ring 41 fits against the center of the wall thickness side of the annular end 422, as shown in the figure. This allows the wall thickness on both sides of the annular end 422 to fit against the screw-in connector 3, improving the connection stability of the overall soft rubber head 4.

[0037] Specifically, the inner material is poured out from the outlet 44 through the contact end 421 in contact with the user's skin. The wiping with the contact end 421 makes the inner material spread evenly. The annular end 422 is used to connect with the connecting ring 41, and sufficient wall thickness is reserved on the inner and outer sides to ensure that both sides fit with the screw head 3, ensuring the stable connection of the soft rubber head 4.

[0038] Furthermore, refer to Figure 4As shown, the end of the contact end 421 with the outlet 44 is an irregular surface 43. The irregular surface 43 can be any irregular surface such as an inclined surface, a concave-convex surface, or a conical surface. The specific application surface is determined by the design requirements. The function of the irregular surface 43 is to increase the contact area with the user's skin and increase the application range. For example, after the material is poured out from the outlet 44, the irregular surface 43 can increase the application area and improve the comfort of use. At the same time, the irregular surface 43 also makes it easier for the user to move the hose along the inclined direction of the irregular surface 43, which has a certain guiding function, making it more convenient to use and conforming to ergonomic design.

[0039] In some embodiments, reference Figure 4 As shown, the inner wall of the annular groove 31 is provided with a wavy groove 5, and the wall of the connecting ring 41 opposite to the wavy groove 5 is provided with a staggered wavy groove 5. The function of the wavy groove 5 is to provide a limiting locking effect. The wall of the connecting ring 41 is also provided with a wavy groove 5, but it is staggered from the groove wall of the annular groove 31, so that the wavy protruding end on the groove wall of the annular groove 31 fits with the wavy concave end on the wall of the connecting ring 41. At the same time, the wavy concave end on the groove wall of the annular groove 31 fits with the wavy protruding end on the wall of the connecting ring 41, thereby achieving a staggered locking effect to increase the tightness when the connecting ring 41 and the annular groove 31 are inserted.

[0040] In some embodiments, reference Figure 4 As shown, based on the irregular surface 43 of the contact end 421, due to the inclination or unevenness of the irregular surface 43, the height of one side of the contact end 421 will be higher or lower than the other side. Therefore, the contact end 421 is divided into the high side 4211 and the low side 4212 based on the two sides with different heights of the irregular surface 43.

[0041] refer to Figure 4 As shown, a first anti-bending piece 32 is provided at the top of the threaded pipe head 3 corresponding to the high side 4211, where it is attached to the outer wall of the contact end 421. The material of the first anti-bending piece 32 is the same as that of the threaded pipe head 3, both of which can be made of plastic. The first anti-bending piece 32 is located on the outer wall of the contact end 421 of the threaded pipe head 3, and its main function is to hold the contact end 421 against it and prevent the contact end 421 from bending when subjected to force.

[0042] Since the contact end 421 is in contact with the user's skin, when the user presses the contact end 421 with force, the irregular surface 43 provides tilt guidance, causing the contact end 421 to bend in the direction of the first anti-bending piece 32. Therefore, the first anti-bending piece 32 is used to resist the bending direction of the contact end 421, thereby preventing the contact end 421 from bending and improving the stability of the soft rubber head 4 in use.

[0043] Further reference Figure 5As shown, a second anti-bending piece 33 is provided at the top of the threaded connector 3 corresponding to the lower side 4212 where it is attached to the inner wall of the contact end 421. The second anti-bending piece 33 is similar to the first anti-bending piece 32, with the same material, but its size can be slightly smaller than the first anti-bending piece 32. This is because it abuts against the inner wall of the contact end 421, and the inner diameter of the contact end 421 is smaller than its outer diameter. Therefore, the second anti-bending piece 33 can be smaller than the first anti-bending piece 32.

[0044] The first anti-bending piece 32 abuts against the outer wall of the contact end 421, while the second anti-bending piece 33 abuts against the inner wall of the contact end 421, thereby achieving two-point contact and further increasing the anti-bending effect.

[0045] The anti-bending effect requires the irregular surface 43 to be in accordance with the tilting and guiding effect of the irregular surface 43. The user will apply force according to the tilting direction of the irregular surface 43. Therefore, the force caused by the contact between the irregular surface 43 and the user's skin can be accurately transmitted to the first anti-bending piece 32 and the second anti-bending piece 33.

[0046] Furthermore, refer to Figure 6 As shown, both the first anti-bending sheet 32 ​​and the second anti-bending sheet 33 are semi-circular sheet structures (the shape of the second anti-bending sheet 33 is obscured in the figure). The semi-circular sheet structure can reduce the area required for the material, and the bonding effect of the semi-circular sheet structure is more stable, without sharp edges or other issues that would affect the user experience.

[0047] Further, refer to Figure 4 As shown, the first anti-bending piece 32 and the second anti-bending piece 33 are both provided with wavy grooves 5 on their contact surfaces with the contact end 421, and the opposite contact ends 421 are provided with staggered wavy grooves 5. By using the first anti-bending piece 32 and the second anti-bending piece 33 to provide wavy grooves 5, and by providing staggered wavy grooves 5 on the contact end 421, the soft rubber head 4 can use the first anti-bending piece 32 and the second anti-bending piece 33 to provide a more stable connection with the connecting ring 41. At the same time, the two staggered wavy grooves 5 can increase the friction between the contact end 421 and the first anti-bending piece 32 and the second anti-bending piece 33, so that when the first anti-bending piece 32 and the second anti-bending piece 33 provide anti-bending, slippage or misalignment of force can be reduced.

[0048] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
