Description

Technical Field

[0001] This utility model belongs to the field of packaging technology for paste-like substances, and in particular relates to an octagonal lid-top device. Background Technology

[0002] In the packaging industry, many paste products, such as toothpaste and ointment, are often packaged using tubular fittings.

[0003] Existing packaging has a simple cap and nozzle sealing structure with poor sealing performance. External air, moisture or impurities can easily enter the tube through gaps, causing the paste to deteriorate and become contaminated, shortening the product's shelf life. This not only leads to product waste but may also pollute the packaging and the surrounding environment. Utility Model Content

[0004] This utility model addresses the problem that existing technologies have simple cap-mouth sealing structures with poor sealing performance, allowing external air, moisture, or impurities to easily enter the tube through gaps, causing the ointment to deteriorate and become contaminated, shortening the product's shelf life, resulting in product waste, and potentially polluting the packaging and the surrounding environment. The following technical solution is proposed: An octagonal lid-on device, comprising: The tube is used to contain and store paste-like substances; A pipe cap is attached to the pipe opening of the pipe body; A sealing assembly includes a convex ring, a fixed seat, and a seal. The convex ring is connected to the bottom end of the pipe cap, the fixed seat is connected to the pipe body, and the seal is disposed inside the fixed seat.

[0005] As a preferred embodiment of the above technical solution, the number of the sealing elements is provided in two sets, and the distance between the two sealing elements is less than the thickness of the convex ring.

[0006] As a preferred embodiment of the above technical solution, the inner wall of the pipe cover is provided with internal threads and is installed to the outer surface of the pipe opening through a threaded connection, and the pipe cover is made of zinc alloy material.

[0007] As a preferred embodiment of the above technical solution, it further includes an extrusion assembly, the extrusion assembly comprising: A movable block, located inside the tube, is used to squeeze out the paste-like substance; A rotating rod is rotatably connected inside the tube body and is used to drive the movable block to move; The mounting bracket is connected to the top of the inner wall of the tube and is used to support the rotating rod.

[0008] As a preferred embodiment of the above technical solution, the bottom end of the tube is provided with a sealing cap, which is sleeved onto the outer surface of the rotating rod.

[0009] As a preferred embodiment of the above technical solution, the bottom end of the rotating rod is connected to a handle, and the outer surface of the handle is connected to a resistance pad.

[0010] The beneficial effects of this utility model are as follows: (1) The present invention can insert the convex ring into the fixed seat by setting the sealing component. Since the distance between the two sealing components is less than the thickness of the convex ring, the two sealing components can fit tightly against the outer surface of the convex ring, effectively eliminating the small gaps that are easy to occur in the traditional sealing structure, fundamentally reducing the risk of leakage of paste-like substances during transportation, storage or pressure, while blocking external air, moisture and impurities from entering the tube, and extending the shelf life of the product. (2) By setting the extrusion component, the movable block can move in the tube and gradually push the residual paste-like substance (such as toothpaste, ointment, skin care product, etc.) towards the tube opening when it moves in the tube. This avoids the problem that the paste-like substance cannot be completely squeezed out due to the residue on the tube wall in the later stage of traditional tube fittings, which significantly improves the product utilization rate. At the same time, it is easy to adjust the moving distance of the movable block, and can accurately control the amount of paste-like substance squeezed out, avoiding waste caused by excessive squeezing or affecting the use effect by insufficient squeezing.

[0013] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0014] Example 1 This utility model provides an octagonal cap cover device, such as... Figures 1 to 5As shown, the octagonal cap device includes a tube body 1, a cap 2, and a sealing assembly. The tube body 1 is used to contain and store the paste-like substance, and the cap 2 is connected to the tube opening 3 of the tube body 1. The sealing assembly includes a convex ring 4, a fixing seat 5, and sealing elements 6. The convex ring 4 is integrally formed and installed at the bottom end of the cap 2. The fixing seat 5 is fixedly installed on the top outer surface of the tube body 1, and two sealing elements 6 are embedded inside the fixing seat 5. Both sealing elements 6 are sealing rings made of rubber material. At the same time, the distance between the two sealing elements 6 is less than the thickness of the convex ring 4. When the convex ring 4 is inserted into the interior of the fixing seat 5, it will simultaneously squeeze the two sets of sealing elements 6, so that the sealing elements 6 can fit tightly against the outer surface of the convex ring 4.

[0015] The inner wall of the pipe cap 2 is internally threaded and installed on the outer surface of the pipe opening 3 through a threaded connection. The pipe cap 2, made of zinc alloy, has high strength and durability. The pipe cap 2 utilizes the rigidity of its metal to ensure that it can be tightly threaded at the pipe opening 3 of the pipe body 1.

[0016] By inserting the protruding ring 4 into the interior of the fixing seat 5 and tightly fitting it with the two sets of sealing elements 6, the pipe opening 3 can be blocked and sealed, ensuring that outside air will not enter the interior of the pipe body 1 along the gap, thus preventing the leakage of paste-like substances from the pipe body 1.

[0017] During use, the user aligns the cap 2 with the opening 3 of the tube body 1 and screws the cap 2 onto the opening 3. As the cap 2 is screwed onto the opening 3, the convex ring 4 gradually moves closer to the fixed seat 5. By continuing to rotate the cap 2, the convex ring 4 is inserted into the interior of the fixed seat 5. Since the distance between the two sealing elements 6 is less than the thickness of the convex ring 4, when the convex ring 4 is inserted into the interior of the fixed seat 5, the two sealing elements 6 can fit tightly against the outer surface of the convex ring 4, effectively eliminating the small gaps that are prone to occur in traditional sealing structures. This fundamentally reduces the risk of leakage of paste-like substances during transportation, storage, or under pressure, while also preventing external air, moisture, and impurities from entering the tube, thus extending the product's shelf life.

[0018] In order to squeeze out the paste-like substance remaining on the inner wall of the tube 1, the extrusion assembly of the octagonal cap device includes a rotating rod 7, a movable block 8, and a mounting frame 9. The rotating rod 7 is rotatably installed inside the tube 1, the movable block 8 is threaded onto the outer surface of the rotating rod 7, and the mounting frame 9 is fixedly installed on the inner wall of the tube 1, with the top end of the rotating rod 7 rotatably installed in the mounting frame 9. The outer surface of the movable block 8 is also integrally formed with a protrusion, and a groove is opened inside the tube 1 corresponding to the outer surface of the protrusion, so that the movable block 8 can reciprocate along the trajectory of the groove inside the tube 1.

[0019] The bottom end of the rotating rod 7 is fixedly connected to the handle 11. The outer surface of the handle 11 is provided with a resistance pad 12. By increasing the friction of the outer surface of the resistance pad 12, the resistance pad 12 can effectively prevent the hand from slipping during the rotation process.

[0020] By gripping and rotating the handle 11, the rotating rod 7 rotates inside the tube body 1. When the rotating rod 7 rotates, it drives the movable block 8 to move towards the tube opening 3 through the threaded connection. When the movable block 8 moves, it can gradually push the paste-like substance remaining on the inner wall of the tube body 1 towards the tube opening 3, avoiding the problem of paste residue not being completely squeezed out due to the later use of traditional tube fittings. At the same time, it is easy to adjust the moving distance of the movable block 8, which can accurately control the amount of paste-like substance squeezed out, avoiding excessive squeezing and waste or insufficient squeezing and affecting the use effect.

[0021] The bottom end of the tube body 1 is equipped with a sealing cap 10, which is fitted onto the outer surface of the rotating rod 7. The sealing cap 10 can effectively seal the gap between the bottom end of the tube body 1 and the rotating rod 7, preventing external dust, moisture, impurities, etc. from entering the tube body 1 through the gap, thus preventing the paste from being contaminated or deteriorated. At the same time, it can further prevent the paste inside the tube from leaking from the bottom gap, forming a "two-way seal" with the sealing component at the tube cap 2, thereby comprehensively improving the sealing reliability of the packaging.

[0022] Working principle: When in use, the user aligns the pipe cap 2 with the pipe opening 3 of the pipe body 1 and screws the pipe cap 2 onto the pipe opening 3. As the pipe cap 2 is screwed onto the pipe opening 3, the convex ring 4 gradually moves towards the fixed seat 5. Continue to rotate the pipe cap 2, and then insert the convex ring 4 into the interior of the fixed seat 5. Since the distance between the two sealing elements 6 is less than the thickness of the convex ring 4, when the convex ring 4 is inserted into the interior of the fixed seat 5, the two sealing elements 6 can fit tightly against the outer surface of the convex ring 4, effectively eliminating the small gaps that are easy to occur in traditional sealing structures, blocking external air, moisture, impurities, etc. from entering the pipe, and extending the product shelf life. When it is necessary to squeeze out the paste-like substance remaining on the inner wall of the tube body 1, by holding and rotating the handle 11, the rotating rod 7 rotates inside the tube body 1. When the rotating rod 7 rotates, it drives the movable block 8 to move towards the tube opening 3 through the threaded connection. When the movable block 8 moves, it can gradually push the paste-like substance remaining on the inner wall of the tube body 1 towards the tube opening 3, avoiding the problem that the paste cannot be completely squeezed out due to the residue on the tube wall in the later stage of traditional pipe fittings.

[0023] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
