Description

Technical Field

[0001] The utility model relates to the technical field of sealing covers, and more specifically to a glue cover and a gasket thereof. Background Art

[0002] Many containers require a sealing lid to prevent the liquid in the container from leaking out, and glue bottles are no exception. To prevent leakage after the lid is tightened, a ring-shaped gasket needs to be configured inside the lid.

[0003] Due to the influence of factors such as the hardness of the iron sheet, the mold precision, and the gasket mold precision when stamping the lid, the inner diameter of the manufactured lid and the outer diameter of the gasket will have tolerances, resulting in a certain degree of mismatch between the gasket and the lid. If the outer diameter of the gasket is large, the gasket will bulge when placed in the lid. If the outer diameter of the gasket is small, the gasket will fall off when the lid is turned upside down after placement. To overcome this problem, the gasket will be glued to the lid with glue. However, gaskets with large outer diameters that bulge during assembly can only be discarded or cut again.

[0004] In addition, the glue is contained in the glue bottle. When you need to apply glue, open the lid of the glue bottle, take out the glue brush, insert it into the glue bottle to dip in the glue, and after using up the glue, tighten the lid and put the glue brush aside. If you do not use the glue brush for a period of time, the glue brush will be dried out and the glue brush will be scrapped, which is very wasteful. Moreover, the glue brush will dip into more glue, and the glue on the glue brush will not be applied completely, which will also cause waste. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a glue cover and a gasket thereof. The gasket body has a high degree of adaptability with the cover body, and the gasket body will not bulge or fall off during assembly. The glue cover has a brush head, which is convenient for dipping glue and avoids air drying and waste.

[0006] According to one aspect of the utility model, a glue cover is provided, which includes a cover body and a gasket body, wherein the cover body is a structure having a top surface at one end and a circular open mouth at the other end, the gasket body is placed at the inner wall of the top surface of the cover body, the outer shape of the gasket body is a circular thin sheet, the outer edge of the gasket body is provided with at least one convex point protruding outward, the convex point extends outward in the horizontal direction along the outer edge of the gasket body, the gasket body is clamped in the side wall of the cover body through the convex point, and there is a gap between the outer edge of the gasket body and the side wall of the cover body at the position where the convex point is not located. Thus, the gasket body can be clamped in the cover body through the convex points on its outer periphery, the diameter of the outer edge of the gasket body is smaller than the inner diameter of the side wall of the cover body, and during assembly, the situation that the gasket body bulges due to the slightly larger diameter of the gasket body can be avoided, and the clamping of one or more convex points can also prevent the gasket body from automatically falling relative to the cover body. This structure greatly improves the adaptability of the gasket body and the cover body, and the gasket body and the cover body do not need to be glued.

[0007] In some embodiments, the center of the gasket body is a hollow structure to form a ring shape with an inner edge, and the glue cover also includes a brush rod and a brush head, the brush head is fixed to one end of the brush rod, and the other end of the brush rod passes through the center of the gasket body and is fixed to the inner wall of the top surface of the cover body. Thus, the glue cover is equipped with a brush head through the brush rod, which is convenient for dipping glue. After use, after the glue cover is assembled with the bottle body, the brush head is placed back in the glue bottle to avoid air drying and waste.

[0008] In some embodiments, a circle of vertically arranged anti-skid ribs is provided at one end of the side wall of the cover body close to the top surface, and the anti-skid ribs form a plurality of grooves in the side wall of the cover body, and the convex points of the gasket body are embedded in the grooves. Thus, the arrangement of the anti-skid ribs, on the one hand, facilitates the operator to unscrew or tighten, and on the other hand, enables the convex points to be embedded in the grooves of the anti-skid ribs to clamp the convex points for positioning.

[0009] In some embodiments, the brush rod is made of metal, and the top of the brush rod is bent into an annular fixing ring to fix the brush head. The end of the brush rod connected to the cover body is bent with a fixing portion, and the rod body of the brush rod is formed between the annular fixing ring and the fixing portion. The diameter of the inner edge of the gasket body is larger than the size of the fixing portion, and the fixing portion is exposed in the inner edge of the gasket body. As a result, the fixing structure of the brush head is simple, the gasket body does not interfere with the fixing portion of the brush rod, and does not affect the fixing of the fixing portion to the cover body.

[0010] In some embodiments, the fixing part is a circular ring structure, the fixing part and the brush rod are perpendicular, the end surface of the fixing part can make the rod stand upright, and the fixing part is fixed to the top surface of the cover body by soldering. Therefore, the fixing part adopts a circular ring structure and the end surface is flat, which is convenient for fitting with the inner wall of the top surface of the cover body, and convenient for fixing the fixing part to the top surface of the cover body.

Therefore, the gasket body can be clamped in the cover body through the convex points on its outer periphery, reducing the situation of the gasket body bulging or falling due to processing tolerance. The design of this structure greatly improves the adaptability of the gasket body and the cover body. The gasket body is not only suitable for glue covers, but also suitable for other sealing covers.

[0013] In some embodiments, the center of the gasket body is a hollow structure, so that the gasket body forms a circular ring shape with an inner edge. Therefore, the gasket body adopts a circular ring structure, which is also applicable to those structures with non-planar top surface designs of the cover body.

[0014] In some embodiments, the gasket body is provided with a plurality of protrusions, and the plurality of protrusions are evenly distributed circumferentially along the outer edge of the gasket body.

[0020] The utility model is further described below in conjunction with specific implementation methods.

[0021] like Figure 1 and 2 As shown, a gasket according to one embodiment of the utility model comprises a gasket body 2, the outer shape of which is a circular thin sheet, and the outer edge 21 of the gasket body 2 has at least one or more evenly distributed and outwardly protruding convex points 22, and the convex points 22 extend outwardly in the horizontal direction along the outer edge 21 of the gasket body 2. The convex points 22 of the gasket body 2 are used for snapping into the matching cover body 1. When the gasket body 2 and the cover body 1 are assembled, there is a gap 100 between the outer edge 21 of the gasket body 2 where the convex points 22 are not located and the side wall 12 of the cover body 1, that is, the outer diameter of the main shape of the gasket body 2 (where the convex points 22 are not located) is smaller than the inner wall diameter of the cover body 1, as shown in FIG. Figure 4 shown.

[0022] The gasket body 2 can be stuck in the cover body 1 through the protrusions 22 on its outer circumference, reducing the situation where the gasket body 2 bulges or falls due to processing tolerances. The design of this structure greatly improves the compatibility between the gasket body 2 and the cover body 1.

[0023] The gasket has a wide range of applications. In specific applications, the gasket body 2 can be a circular thin sheet without a hollow center; the center of the gasket body 2 can also be a hollow structure, so that the gasket body 2 forms a circular ring shape with an inner edge 23. In this way, the gasket body 2 adopts a circular ring structure, which is also applicable to structures with non-planar design of the top surface 11 of the cover body 1.

[0024] In practical applications, the number of protrusions 22 can be increased or decreased according to the diameter of the outer edge 21 of the gasket body 2. In this embodiment, the gasket body 2 has six protrusions 22, and the six protrusions 22 are evenly spaced circumferentially along the outer edge 21 of the gasket body 2.

[0025] like Figure 3 and 4As shown, the gasket body 2 provided above is applied to the glue cap. Specifically, the glue cap includes a cap body 1 and the gasket body 2. The cap body 1 is a structure with a top surface 11 at one end and a circular open mouth at the other end. The side wall 12 of the cap body 1 can be provided with an internal thread (not shown) adapted to the glue bottle as required. The center of the gasket body 2 is a hollow structure to form a circular ring shape with an inner edge 23. The gasket body 2 has six convex points 22. The gasket body 2 is placed on the inner wall of the top surface 11 of the cap body 1. The gasket body 2 is stuck in the side wall 12 of the cap body 1 through the convex points 22. There is a gap 100 between the outer edge 21 of the gasket body 2 and the side wall 12 of the cap body 1 where the convex points 22 are not located. The diameter of the circle at the outermost end of the convex point 22 is greater than that of the side wall 12 of the cap body 1, and the diameter of the connection between the top surface 11 and the side wall 12 does not exceed 0.5 mm. The glue cover also includes a brush rod 3 and a brush head 4. The brush head 4 is fixed to one end of the brush rod 3. The other end of the brush rod 3 passes through the center of the gasket body 2 and is fixed to the inner wall of the top surface 11 of the lid body 1. The glue cover is installed with the brush head 4 through the brush rod 3, which is convenient for dipping glue. After use, after the glue cover is assembled with the bottle body, the brush head 4 is placed back in the glue bottle to avoid air drying and waste. When the gasket body 2 is hollow in the middle, an overall circular ring structure is formed, which does not affect the installation of the brush rod 3.

[0026] Specifically, the brush rod 3 is made of metal. The top of the brush rod 3 is bent to form an annular fixing ring 31, and the fixing ring 31 fixes the brush head 4. The other end of the brush rod 3 is also bent to form a fixing portion 32, which is a circular ring structure. The fixing portion 32 is perpendicular to the main body of the brush rod 3, and the end face of the fixing portion 32 allows the rod body 30 to be upright. The fixing portion 32 is fixed to the top surface 11 of the cover body 1 by solder paste or solder. The rod body 30 of the brush rod 3 is formed between the annular fixing ring 31 and the fixing portion 32. The diameter of the inner edge 23 of the gasket body 2 is larger than the size of the fixing portion 32, and the fixing portion 32 is exposed in the inner edge 23 of the gasket body 2. The brush rod 3 is an integrated structure, and the fixing structure of the brush head 4 and the brush rod 3 is simple; the fixing portion 32 adopts a circular ring structure and the end surface is flat, which is convenient for fitting with the inner wall of the top surface 11 of the cover body 1, and convenient for fixing the fixing portion 32 to the top surface 11 of the cover body 1; the gasket body 2 does not interfere with the fixing portion 32 of the brush rod 3, and does not affect the fixation of the fixing portion 32 to the cover body 1.

[0027] A circle of vertically arranged anti-skid ribs 13 is processed at one end of the side wall 12 of the cover body 1 close to the top surface 11. The anti-skid ribs 13 form a plurality of grooves 14 in the side wall 12 of the cover body 1, and the convex points 22 of the gasket body 2 are embedded in the grooves 14. In this way, the arrangement of the anti-skid ribs 13, on the one hand, facilitates the operation of unscrewing or tightening by the operator, and on the other hand, enables the convex points 22 to be embedded in the grooves 14 of the anti-skid ribs 13 to clamp the convex points 22 for positioning.

[0028] The utility model provides a novel gasket structure, wherein one or more outwardly protruding convex points 22 are arranged on the outer edge 21 of the gasket body 2, the diameter of the outer edge 21 of the gasket body 2 is smaller than the inner diameter of the side wall 12 of the lid body 1, and the gasket body 2 is clamped in the lid body 1 by the convex points 22, which can avoid the problem of the gasket body 2 and the lid body 1 not being compatible due to processing tolerance, avoid the gasket body 2 being relatively too large to cause bulging, and avoid the gasket body 2 being relatively too small to cause falling when buckled with the bottle body. The design of the gasket structure greatly improves the adaptability of the gasket body 2 and the lid body 1, and with the convex points 22, the gasket body 2 and the lid body 1 do not need to be glued during assembly, and they will not fall off without gluing. The gasket of the novel structure is not only suitable for glue caps, but also for the caps of other containers.

[0029] The above are only some embodiments of the present invention. It should be pointed out that for ordinary technicians in this field, other modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
