TECHNICAL FIELD
[0001] The utility model belongs to the field of bottle mouth sealing, specifically relates to a bottle mouth sealing sheet. BACKGROUND
[0002] The design of the bottle mouth sealing structure is to ensure that the substances in the bottle do not leak, and also prevent the intrusion of external pollutants.
[0003] At present, the bottle mouth sealing structure existing in the market has the following implementation modes: 1. No gasket sealing structure: this structure usually includes three seals, which are a sealing ring, a top sealing ring and a side sealing ring. The sealing ring is deeply inserted into the inside of the bottle mouth, the top sealing ring is pressed on the bottle mouth plane, and the side sealing ring is surrounded on the outside of the top of the bottle mouth. This design ensures that the beverage does not leak and deteriorate when being squeezed or collided during transportation or transportation; 2. Sterile cover sealing structure: the sterile cover also includes a three-seal structure, i.e. a sealing ring, a top sealing ring and a side sealing ring. After the cover is sealed, the sealing ring is deeply inserted into the inside of the bottle mouth, and the top sealing ring and the side sealing ring play an auxiliary sealing role; 3. Water cover sealing structure: the water cover sealing design is a two-seal structure, which is a sealing ring and a side sealing ring from inside to outside. After the cover is sealed, the sealing ring is deeply inserted into the inside of the bottle mouth, and plays a main sealing role; the side sealing ring is tightly attached to the outside of the top of the bottle mouth, and plays an auxiliary sealing role.
[0004] However, the above implementation requires the setting of multiple accessories (rings or rings), and the sealing effect is achieved by using them together, so on the one hand, if the multiple accessories are not properly matched, the sealing will fail; on the other hand, the multiple accessories also make it difficult to reduce the material cost. TECHNICAL FIELD
[0005] In view of the deficiencies of the prior art, the utility model provides a bottle mouth sealing sheet, which can realize effective sealing of the bottle mouth through the opening and closing action of the bottle cap on the bottle mouth.
[0006] To achieve the above purpose, the utility model provides the following technical scheme:
[0007] A bottle mouth sealing sheet, the bottle mouth has a bottle mouth end face, a bottle neck inner wall and a transition slope face, the bottle mouth end face has a continuous sealing subface and a sunken step, the sunken step is continuous to the bottle neck inner wall through the transition slope face, the bottle mouth is opened and closed by moving towards or away from the sealing subface along the bottle neck direction through the bottle cap, characterized by: a lap flange part, a transition sealing part and a bottle mouth shielding part are sequentially and continuously arranged, the lap flange part is arranged in the sunken step, and the thickness of the lap flange part is greater than the depth of the sunken step, the transition sealing part is arranged on the transition slope face, and the bottle mouth shielding part is arranged on the bottle mouth, wherein the surface of the transition sealing part is formed with a sealing convex rib, the sealing convex rib extends along the circumference of the bottle neck, and the minimum distance between the sealing convex rib and the surface of the transition slope face is less than a predetermined value.
[0008] Preferably, the bottle mouth shielding part is located in the bottle neck, the bottle mouth shielding part is in the shape of a conical surface, and the tip of the conical surface faces the inner side of the bottle mouth.
[0009] Preferably, the utility model further includes a uniform force gasket, which is correspondingly arranged on the end face of the bottle mouth and is in surface contact with the upper surface of the lap joint flange.
[0010] Preferably, the surface of the bottle mouth shielding part facing the outer side of the bottle mouth is provided with a pull-tab sub-piece through a live hinge process.
[0011] Compared with the prior art, the utility model has the beneficial effects that:
[0012] 1. Because the bottle mouth sealing piece of the utility model has a lap joint flange part, a transition sealing part and a bottle mouth shielding part in sequence, the lap joint flange part is arranged in the sunken step, the thickness of the lap joint flange part is greater than the depth of the sunken step, the transition sealing part is arranged on the transition slope, the bottle mouth shielding part is arranged on the bottle mouth, the surface of the transition sealing part is formed with a sealing convex rib, the sealing convex rib extends along the circumference of the bottle neck, and the minimum distance between the sealing convex rib and the surface of the transition slope is less than a predetermined value. When the bottle cap closes the bottle mouth, the bottle cap moves along the bottle neck direction by moving towards the sealing sub-surface, presses the lap joint flange part, forms extrusion on the adjacent transition sealing part, and the transition sealing part expands due to the extrusion, thereby driving the sealing convex rib to press on the transition slope, i.e. forming a sealing structure on the transition slope. Therefore, the utility model can realize effective sealing of the bottle mouth only through the opening and closing action of the bottle cap on the bottle mouth.
[0013] 2. Because the bottle mouth shielding part of the utility model is located in the bottle neck, the bottle mouth shielding part is in the shape of a conical surface, and the tip of the conical surface faces the inner side of the bottle mouth, when the fluid in the bottle produces a "wall hanging" phenomenon on the inner side surface of the bottle mouth shielding part of the utility model, the inner side surface of the bottle mouth shielding part is more conducive to the backflow of the fluid into the bottle.
[0014] 3. Because the surface of the bottle mouth shielding part facing the outer side of the bottle mouth of the utility model is provided with a pull-tab sub-piece through a live hinge process, the utility model can conveniently pull the bottle mouth sealing piece away from the bottle mouth through the pull-tab sub-piece.
