Abstract
The utility model provides a container mouth sealing structure, which comprises a container cover and a container mouth, wherein the container cover is in threaded connection with the container mouth; the inner annular wall and the outer annular wall are downward bulges which are downward-suspended and downwardly protruded from the top wall of the inner side of the container cover; the top of the container opening is provided with an outward protruding part matched with the outer side annular wall, and in the screwing process of the container cover, the outward protruding part is contacted with the outer side annular wall only after the inner side annular wall is contacted with the inclined plane or the cambered surface of the container opening. The utility model discloses seal structure's sealing performance is more reliable. And automatic adjustment and balanced sealing are convenient for full-automatic screwing operation on the production line.
Description
Technical Field
The utility model relates to a container mouth seal structure field.
Background
For sealing the bottle mouth, one current method is to screw down the cap and seal the bottle mouth by matching the inner side inclined plane with the inner wall inclined plane of the bottle mouth. This structure is not good in the consistency of the sealing degree, and is liable to affect the sealing effect because the sealing is not yet in place, and also liable to require an excessively large force for opening operation because the sealing is too tight.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a container mouth seal structure that seal structure good reliability is provided. Therefore, the utility model adopts the following technical scheme:
a container mouth sealing structure comprises a container cover and a container mouth, wherein the container cover is in threaded connection with the container mouth;
the inner annular wall and the outer annular wall are downward bulges which are downward-suspended and downwardly protruded from the top wall of the inner side of the container cover; the top of the container opening is provided with an outward protruding part matched with the outer side annular wall, and in the screwing process of the container cover, the outward protruding part is contacted with the outer side annular wall only after the inner side annular wall is contacted with the inclined plane or the cambered surface of the container opening.
Further, in an axial section of the outer annular wall, the profile length of the outer side of the protrusion is smaller than the profile length of the inner side of the protrusion.
Further, the outer annular wall is provided with a boss inner root portion at a higher position than a boss outer root portion in an axial cross section.
Owing to adopt the technical scheme of the utility model, compare in the outside for the structure of step, the utility model discloses seal structure's sealing performance is more reliable, avoids withholding or blocking when can avoiding the spiral cover through the deflection of outside annular wall to automatically regulated and balanced sealed, carry out full-automatic spiral cover operation on the production line of being convenient for.
Drawings

Fig. 2 is an enlarged view of a portion a in fig. 1.
Detailed Description
Referring to the drawings, the utility model provides a container mouth seal structure, including container lid 1 and container mouth 2, container lid 1 and container mouth 2 threaded connection, the top in the container lid 1 is provided with inboard annular wall 11 and outside annular wall 12, and inboard annular wall 11 seals up the cooperation when container lid 1 screws up with the inclined plane 21 of container mouth, have the cooperation of protruding 3 and annular groove 4 between inboard annular wall 11 and the inclined plane 21, and when protruding 3 gets into annular groove 4, be in encapsulated situation between the inclined plane 21 of the inboard annular wall 11 of container lid 1 and container mouth.
The inner annular wall 11 and the outer annular wall 12 are downward bulges in a downward hanging annular shape which are protruded downwards from a top wall 13 at the inner side of the container cover, and the bottom end of the inner annular wall 11 is lower than that of the outer annular wall 12; preferably, in an axial section of the outer annular wall 12, a profile length of the projection outer side 121 is smaller than a profile length of the projection inner side 122, and a position of the projection inner side root 124 is higher than a position of the projection outer side root 123.
The downward-hanging annular downward bulge is arranged in the axial section, the outline length of the outer side of the bulge is smaller than that of the inner side of the bulge, and the root arrangement position of the inner side of the bulge is higher than that of the outer side of the bulge.
The top of the container opening is provided with an outward bulge part 22 matched with the outer side annular wall 12, and in the process of screwing the container cover, the outward bulge part 22 is contacted with the outer side annular wall 12 only after the contact between the inner side annular wall 11 and the inclined surface 21 of the container opening, and is contacted before the bulge 3 is clamped into the annular groove 4. When the cover is closed, the inclined surface 21 is firstly contacted with the inner annular wall 11, the inclined surface 21 can deform outwards after the contact, when the outward protruding part 22 is contacted with the outer annular wall 12, the outer annular wall 12 in a cantilever shape can be pressed to deform towards the outside slightly integrally, the hard top is prevented from being clamped, the reaction force after the deformation is larger, the outward protruding part 22 is squeezed inwards, the outward deformation of the inclined surface 22 is reduced, and the sealing effect of the inclined surface 22 and the inner annular wall 1 is enhanced.
The projection 3 may be an annular projection. The annular groove 4 may be provided in one of the inner annular wall 11 and the container mouth chamfer 21, and the protrusion 3 may be provided in the other of the inner annular wall 11 and the container mouth chamfer 21. Preferably, the protrusion 3 is disposed outside the inner annular wall 11, and the annular groove 4 is disposed on the inclined surface 21. The projection 3 and the annular groove 4 are in sealing engagement when the projection 3 enters the annular groove 4.
In the implementation, also can not set up arch 3 and annular groove 4 adopt the utility model discloses a hang down outside annular wall 12 and outside bulge 22 cooperation down, can play foretell technological effect equally.
The above description is only for the specific embodiment of the present invention, but the structural features of the present invention are not limited thereto, and any person skilled in the art is in the field of the present invention, and all the changes or modifications are covered in the protection scope of the present invention.
