Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bottles or barrels containing media, in particular to a cover structure. Background Art
[0002] When the sealing cap is in use, it is necessary to ensure the pressure balance inside and outside the container to avoid being locked too tightly and difficult to open. The usual design is to set a through hole at the bottom of the cap body to achieve communication between the inside and the outside. When the cap is unscrewed, the internal air pressure flows out through the exhaust plug installed on the cap plug, and then flows into the space between the cap plug and the cap body, and then flows out from the hole on the cap body, achieving air pressure balance and ensuring that the cap can be opened smoothly.
[0003] However, in this process, due to the yield problem of the holes in the cover, the inserted holes can easily cause debris to stick to the inner wall of the hole, affecting the ventilation effect of the hole. Moreover, in the storage environment, the cover with holes can easily allow external dirt to flow into the gaps in the barrel, affecting the use of the barrel cover.
[0004] At the same time, in the process of unscrewing the lid, it is easy for the lid plug to fit too tightly with the inner wall of the lid, so that there is no gap or the gap is very small between the two, which also affects the opening and use of the lid. Utility Model Content
[0005] The technical problem to be solved by the utility model is to provide a cover structure in view of the above-mentioned technical deficiencies. The first groove and the second groove arranged on the bottom of the cover body and the third groove on the side wall cooperate to achieve the exhaust function in the case of no jack, only by means of the preset groove of the mold, thereby avoiding the problem that the jack yield rate affects the use of the cover with jack ventilation, and also saves the work flow. The groove is preset on the mold, and no subsequent jack link is required after molding. At the same time, the protrusion arranged on the cover plug maintains a certain gap between the cover plug and the cover body, thereby ensuring the ventilation performance during exhaust and avoiding affecting the use.
[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is: a cover body, the cover body is arranged to open toward the mouth side, and a cover plug for sealing is installed in the cover body; the cover plug is installed at the bottom of the cover body; the cover plug is provided with a limiting groove for installing an exhaust plug toward the mouth side; a through hole connecting the two sides of the cover plug is provided in the upper limit groove of the cover plug; a first groove is provided on the outer side of the cover body corresponding to the through hole; a second groove is provided to diffuse and connect from the first groove to the edges around the inner bottom of the cover body.
[0007] To further optimize the technical solution, the first groove is an annular through groove; the second groove is a straight groove connected to the annular through groove to the periphery of the inner bottom of the cover body.
[0008] To further optimize the technical solution, a third groove extending in axial length is provided on the inner wall of the cover body; one end of the third groove is connected to the second groove; and the axial length of the third groove is greater than the thickness setting around the cover plug.
[0009] To further optimize the technical solution, the outer side of the cover plug is clamped in the cover body on all sides.
[0010] To further optimize the technical solution, a protrusion is provided on a side of the cover plug facing the cover body to prevent the cover plug from fitting too closely to the inner bottom of the cover body.
[0011] To further optimize the technical solution, the protrusion is an annular protrusion with a notch.
[0012] To further optimize the technical solution, the protrusion is concentrically arranged in at least one layer on the surface of the plug.
[0013] Compared with the prior art, the utility model has the following advantages: 1. By cooperating with the first groove and the second groove on the bottom of the cover body and the third groove on the side wall, this structure advantageously ensures that in the case of no jack, the exhaust function is achieved only by means of the preset grooves in the mold, avoiding the problem that the jack yield rate of the cover with jack ventilation affects the use, and also saves the work flow, by presetting the grooves on the mold, and no subsequent jack link is required after molding; 2. By means of the protrusions set on the cover plug, this structure advantageously ensures that a certain gap is maintained between the cover plug and the cover body, ensuring the ventilation performance during exhaust and avoiding affecting the use.

[0018] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.
[0019] Specific implementation method: Combination Figure 1-3 As shown, a cover body 1 is arranged with an opening toward the mouth side, and is characterized in that: a cover plug 2 for sealing is installed in the cover body 1; the cover plug 2 is installed at the bottom inside the cover body 1; a limiting groove 3 for installing an exhaust plug is arranged toward the mouth side of the cover plug 2; a through hole 4 connecting the two sides of the cover plug 2 is arranged in the upper limiting groove 3 of the cover plug 2; a first groove 5 is arranged on the outer side of the position corresponding to the through hole 4 on the cover body 1; a second groove 6 is arranged to diffuse and connect from the first groove 5 to the edges around the bottom inside the cover body 1.
[0020] The first groove 5 is an annular through groove; the second groove 6 is a straight groove connected to the inner bottom of the cover body 1. The inner side wall of the cover body 1 is provided with a third groove 7 extending in axial length; one end of the third groove 7 is connected to the second groove 6; the axial length of the third groove 7 is greater than the thickness of the plug 2. The outer side of the plug 2 is clamped in the cover body 1. The plug 2 is provided with a protrusion 8 on one side facing the cover body 1 to prevent the plug 2 from fitting too closely to the inner bottom of the cover body 1. The protrusion 8 is an annular protrusion 8 with a notch 9. The protrusion 8 is concentrically provided with at least one layer on the surface of the plug 2.
[0021] Combination Figure 1-3 As shown, when the lid is opened, the inside of the container is connected with the back of the lid plug 2 through the exhaust plug and the through hole 4. At the same time, the protrusion 8 on the back of the lid plug 2 can prevent the lid plug 2 from fitting too closely with the inside of the lid body 1. At the same time, the notch 9 can prevent the protrusion 8 from forming a seal itself to affect ventilation. Then, in conjunction with the first groove 5, the second groove 6 and the third groove 7, the inside of the container and the surrounding areas of the lid body 1 are connected with the outside world, so that the air pressure in the container is balanced, thereby achieving a better lid opening effect. The first groove 5, the second groove 6 and the third groove 7 are themselves arranged on the lid body 1, and can be obtained by modifying the manufacturing mold of the lid body 1, thereby avoiding the ventilation holes formed by the jacks, increasing the process flow, and the problem of easy adhesion.
