Description

Technical Field

[0001] The present invention relates to the technical field of sealing covers, in particular to a sealing cover structure for a glass sealed jar. Background Art

[0002] Glass jars are widely used for storing food, cosmetics, chemicals, and other products. They need to be isolated from air, moisture, microorganisms, and odors. The sealing of glass jars depends on the sealing cap. Common sealing caps are sealed with a threaded seal and a sealing ring. When the cap is closed, the sealing ring fits tightly against the bottle mouth over a large area. Opening the cap requires a large amount of rotational friction. Therefore, in the existing technology, in many cases, additional tools are required to pry open the cap, which is also quite troublesome.

[0003] Here, in order to solve the above problems, we propose a sealing cover structure for a glass sealed jar. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above technical difficulties and provide a sealing cover structure for a glass sealed jar, which can open and close the sealing cover more labor-savingly by rotating the flange cover.

[0005] In order to solve the above technical problems, the technical solution provided by the present invention is:

[0006] A sealing cover structure for a glass sealed jar comprises a flange gland, a sealing cover, a sealed jar and a sealing ring; the sealing cover is adapted to the bottle mouth of the sealed jar, and after being covered on the bottle mouth of the sealed jar, a sealing ring fixed to the inner top surface of the sealing cover is tightly attached to the top surface of the sealed jar; after being constrained to the inner side of the flange gland, the sealing cover only rotates horizontally within the flange gland; after the flange gland is screwed clockwise or counterclockwise, the flange gland is sleeved and fixed on the bottle mouth of the sealed jar, or can be removed from the bottle mouth of the sealed jar.

[0007] Furthermore, an external thread is formed on the outer wall of the bottle mouth of the sealed can, and a plurality of long strip-shaped ribs are formed inwardly on the bottom edge of the flange cover and are evenly arranged along the circumference. After the flange cover is screwed clockwise or counterclockwise, the flange cover is fixed to the bottle mouth of the sealed can or removed from the bottle mouth of the sealed can through the cooperation between the ribs and the external thread.

[0008] Furthermore, the top edge of the flange gland forms an inwardly rolled edge, and the sealing cover is movably arranged in the flange gland and is confined between the rolled edge and the rib, so that the sealing cover is buckled and pressed on the top of the sealing cover.

[0009] Furthermore, a spring cover is formed in the middle of the sealing cap. The spring cover is a convex groove structure that is deformed by pushing outward or sucking inward under the air pressure in the sealed can. When the excess air in the sealed can is extracted and the sealing cap is tightened, a low vacuum state is generated in the bottle, and the spring cover will keep sinking. When the sealing cap leaks or the bottle cap is opened for the first time, the spring cover will automatically pop up, so that it can be intuitively detected whether there is any air leakage in the sealed state.

[0010] The advantages of the present invention compared with the prior art are:

[0011] 1. The flange gland of the present invention greatly improves the efficiency of converting rotational force into up and down force, thereby reducing friction.

[0012] 2. The top of the sealed can of the present invention is provided with an external thread structure, which can be quickly tightened or opened.

[0013] 3. The present invention can intuitively detect whether there is air leakage in the sealed state by observing the spring cover sinking or bouncing up. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In the description of the present invention, it should be understood that the terms "center", "lateral", "up", "down", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more. In addition, the term "including" and any variations thereof are intended to cover non-exclusive inclusions.

[0021] The present invention will be described in further detail below with reference to the accompanying drawings.

[0022] A sealing cover structure for a glass sealed jar comprises a flange gland 1, a sealing cover 2, a sealed jar 3 and a sealing ring 4; the sealing cover 2 is adapted to the bottle mouth of the sealed jar 3, and after being covered on the bottle mouth of the sealed jar 3, the top surface of the sealed jar 3 is tightly attached to the sealing ring 4 fixed on the inner top surface of the sealing cover 2; after the sealing cover 2 is constrained inside the flange gland 1, it only rotates horizontally inside the flange gland 1; after the flange gland 1 is screwed clockwise or counterclockwise, the flange gland 1 is sleeved and fixed on the bottle mouth of the sealed jar 3, or can be removed from the bottle mouth of the sealed jar 3.

[0023] like Figure 5 As shown, an external thread 7 is formed on the outer wall of the bottle mouth of the sealed can 3. Figure 3 As shown, the bottom edge of the flange gland 1 is formed inwardly with a plurality of long strip-shaped ribs 8 evenly arranged along the circumference. When the flange gland 1 is screwed clockwise or counterclockwise, the flange gland 1 cooperates with the external thread 7 to achieve the flange gland 1 being sleeved and fixed on the bottle mouth of the sealed can 3, or being removed from the bottle mouth of the sealed can 3. The top edge of the flange gland 1 forms an inwardly rolled edge, and the sealing cover 2 is movably arranged in the flange gland 1 and constrained between the curling edge and the ribs 8.

[0024] like Figure 1 、 4 As shown, the sealing ring 4 is annular in design and is placed in the annular groove formed on the lower surface of the sealing cover 2 and is tightly sealed with the top of the sealing can 3. Figure 2 As shown, a spring cover 5 is formed in the middle of the sealing cover 2. The spring cover 5 is a convex groove structure that is deformed by pushing outward or sucking inward under the air pressure in the sealing can 3.

[0025] In the specific implementation of this embodiment:

[0026] After the stored items are filled into the sealed can, the excess air in the sealed can is extracted and the sealing lid is rotated and tightened. A low vacuum state is generated in the sealed can, and the center circle of the sealing lid will remain sunken. When the sealing lid leaks, the food expands due to expiration, or the bottle cap is opened for the first time, the center circle of the sealing lid will automatically pop up, allowing you to intuitively see whether the food in the can is safe to eat.

[0027] When opening the cover, rotate the sealing cover to achieve the effect of opening the cover.

[0028] The present invention and its embodiments are described above. This description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs structures and embodiments similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
