The utility model is described in detail below in combination with the drawings.
[0026] The utility model embodiment provides a novel sealed theftproof cover to be installed on other packaging barrels, packaging bottles or other containers such as chemical barrels, can seal the barrel mouth of the packaging barrel under the condition of screwing the cover, and will not cause the inner cover 200 plugged in the barrel mouth to be deformed and affect the sealing effect due to gradually selecting the cover.
[0027] Specifically, as shown in the figure, Figures 1-5 The utility model embodiment provides a sealed theftproof cover, which comprises an upper cover 100, an inner cover 200 and a theftproof ring 300 connected to the lower end of the upper cover 100, wherein one end of the inner cover 200 is inwardly recessed to form a concave cavity 201, the top of the outer wall of the concave cavity is formed with a sealing ring 210 extending outward in the radial direction, the lower end of the upper cover 100 is further formed with a butt joint cavity 101 corresponding to the container, the inner wall of the butt joint cavity 101 is provided with an internal thread 102, and the top wall of the butt joint cavity 101 is provided with an abutment portion 110 corresponding to the concave cavity 201, when the upper cover 100 covers the inner cover 200 in the butt joint cavity 101, the abutment portion 110 is embedded in the concave cavity 201 and abuts and presses the inner wall of the concave cavity 201.
[0028] That is to say, when assembled on the packaging barrel, the inner cover 200 is used to plug into the barrel opening, the sealing ring 210 on the inner cover 200 overlaps the barrel opening edge, when the upper cover 100 is screwed on the barrel opening, the abutting portion 110 on the top wall of the docking cavity 101 can be embedded into the recess cavity 201 and block and abut against the inner wall of the recess cavity 201, at this time, in the process of screwing the upper cover 100, the upper cover 100 and the barrel opening gradually press the sealing ring 210 to seal, in this process, the abutting portion 110 abuts against the inner wall of the recess cavity 201 to prevent the inner wall of the recess cavity 201 from deforming towards the inside, thereby avoiding the deformation of the sealing ring 210 towards the inside of the barrel opening due to the extrusion of the upper cover 100 and the barrel opening, so as to ensure the sealing effect of the packaging barrel.
[0029] In the embodiment, the abutting portion 110 includes a convex ring formed on the top wall of the docking cavity 101 and coaxial with the docking cavity 101. Figure 2 、 4 As shown in FIG. 5, the abutting portion 110 can be a convex ring structure, so that after the upper cover 100 is tightly covered, the convex ring can be embedded into the recess cavity 201 to abut against the inner wall of the recess cavity 201, so as to prevent the inner wall of the recess cavity 201 from deforming towards the inside.
[0030] In other embodiments, the abutting portion 110 includes a plurality of protrusions formed on the top wall of the docking cavity 101 and arranged along the circumferential direction of the coaxial circle of the docking cavity 101. That is, the abutting portion 110 can be a circular structure surrounded by a plurality of protrusions, or it can be understood that a plurality of notches are arranged on the convex ring to separate the convex ring into a plurality of protrusions. Through the technical solution, the inner wall of the recess cavity 201 can also be abutted against to prevent deformation towards the inside.
[0031] In the embodiment, to further increase the sealing effect, the sealing ring 210 is formed with a first sealing protrusion 211 protruding from the surface of the sealing ring 210 on the side end face away from the opening of the recess cavity 201. In the process of screwing the upper cover 100, the upper cover 100 and the barrel opening clamp the sealing ring 210, the first sealing protrusion 211 increases the air tightness of the sealing ring 210 and the barrel opening, improves the sealing effect, and increases the friction between the sealing ring 210 and the barrel opening through the first sealing protrusion 211, which can effectively prevent the sealing ring 210 from deforming towards the inside of the barrel opening.
[0032] In a further improved scheme, the end face of the sealing ring 210 away from the first sealing protrusion 211 is formed with a second sealing protrusion 212 protruding from the surface of the sealing ring 210. The arrangement of the second sealing protrusion 212 can further improve the stability of the sealing ring 210 and effectively prevent displacement of the sealing ring 210.
[0033] Meanwhile, as shown in Figure 3 the end face of the sealing ring 210 away from the first sealing protrusion 211 is formed with a plurality of air vent grooves 213 opened in the radial direction, and the air vent grooves 213 penetrate the sealing ring 210 in the radial direction. When the upper cover 100 is tightened, the air in the cavity 201 can be discharged through the air vent grooves 213, ensuring the stability of the air pressure in the cavity 201, thereby avoiding the deformation of the inner cover 200 due to the increase of the air pressure.
[0034] In order to connect the inner cover 200 and the upper cover 100, after the upper cover 100 is removed from the packaging barrel, the inner cover 200 can be smoothly removed together from the packaging barrel, as shown in Figures 4-5 the cavity 201 of the inner cover 200 is also formed with an abutting piece 220 protruding from the bottom of the cavity 201, and the end of the abutting piece 220 is formed with an abutting hook portion 221; a clamping piece 120 is formed on the top wall of the abutting cavity 101, and the end of the clamping piece 120 is formed with a clamping hook portion 121 that is clamped with the abutting hook portion 221. After the upper cover 100 is tightened, the abutting piece 220 and the clamping piece 120 are clamped with each other, thereby connecting the upper cover 100 and the inner cover 200, and when the upper cover 100 is removed from the packaging barrel, the inner cover 200 can also be removed together from the packaging barrel, improving the use performance.
[0035] In this embodiment, the structure of the abutting piece 220 and the clamping piece 120 is as follows: the bottom of the cavity 201 is formed with an annular protrusion extending towards the opening direction, the annular protrusion defines the abutting piece 220, and the abutting hook portion 221 is formed at the end of the annular protrusion and protrudes towards the outside or the inside; a plurality of protrusions extending towards the opening direction of the abutting cavity 101 are formed on the top wall of the abutting cavity 101, the plurality of protrusions are arranged along the concentric circles of the abutting cavity 101 to define the clamping piece 120, and the clamping hook portion 121 is formed at the end of the protrusions and protrudes towards the inside or the outside. In short, the abutting piece 220 and the clamping piece 120 are both provided as annular protruding structures, so that the abutting piece 220 and the clamping piece 120 will not interfere with each other when the upper cover 100 is rotated.
[0036] In this embodiment, a plurality of connecting ribs 301 are provided between the upper cover 100 and the anti-theft ring 300, the plurality of connecting ribs 301 are arranged at equal intervals, and the plurality of connecting ribs 301 define a spacing space between the upper cover 100 and the anti-theft ring 300.
