Bottle cap with anti-inclination inner plug

Abstract

The utility model provides a bottle cap with an anti-tilt inner plug, which comprises an aluminum cap, an inner cap, a conjoined cylinder and the inner plug, an inclined plane A is arranged on the conjoined cylinder, an inclined plane B is arranged on the inner plug, the inclined plane A is tightly attached to the inclined plane B, an axial straight plane A is arranged on the conjoined cylinder, an axial straight plane B is arranged on the inner plug, and the axial straight plane A is attached to the axial straight plane B. The inclined surface of the inner plug is attached to the inclined surface of the conjoined cylinder, and meanwhile, the axial straight surface of the inner plug is added to be attached to the straight surface of the conjoined cylinder, so that auxiliary positioning is formed. When the cover is pressed on the bottle opening, the inclined surface of the inner plug bears pressure, and meanwhile, the axial straight surface assists in preventing the inner plug from inclining, so that the defects of inclination of the inner plug and wine leakage caused by non-uniform stress in the technical background are well overcome, the product quality is improved, and later customer complaints are avoided.

Description

Technical Field

[0001] The utility model belongs to the technical field of bottle caps, in particular to a bottle cap with an inner plug to prevent tilting. Background Art

[0002] In the prior art, most bottle caps are mainly composed of four parts: aluminum cap, inner cap, connected cylinder and inner plug. There is a gap between the connected cylinder and the inner plug (see Figure 1 ), when the lid is pressed onto the bottle mouth, the inner plug bears the pressure between the bottle mouth and the connected barrel. If the force is uneven, it is easy to cause the inner plug to move up and tilt, causing wine leakage and affecting product quality. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a bottle cap with an inner stopper to prevent tilting.

[0004] The technical solution of the present utility model is achieved as follows: a bottle cap with an anti-tilt inner plug comprises an aluminum cap, an inner cap, a connected tube and an inner plug, the connected tube is provided with an inclined surface A, the inner plug is provided with an inclined surface B, the inclined surface A is tightly fitted with the inclined surface B, the connected tube is provided with an axial straight surface A, the inner plug is provided with an axial straight surface B, the axial straight surface A is fitted with the axial straight surface B.

[0005] The beneficial effects of the present invention are as follows: the present invention aligns the inclined surface of the inner plug with the inclined surface of the integrated barrel, and at the same time, adds an axial straight surface of the inner plug to align with the straight surface of the integrated barrel to form an auxiliary positioning. When the lid is pressed onto the bottle mouth, the inclined surface of the inner plug bears the pressure, and at the same time, the axial straight surface helps prevent the inner plug from tilting, effectively solving the problem of inner plug tilting and wine leakage caused by uneven force in the technical background, improving product quality, and avoiding the occurrence of customer complaints in the future.

[0011] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0012] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0013] Refer to the attached Figure 2-4 : A bottle cap with an anti-tilting inner plug, comprising an aluminum cap 1, an inner cap 2, a connected tube 3 and an inner plug 4. The inner cap 2 is rotated clockwise and tightened with the connected tube 3. Hot melt adhesive is used to bond the aluminum cap 1 to the assembled inner cap 2 and connected tube 3, and finally the inner plug 4 is assembled into the connected tube 3. The inclined surface A6 of the connected tube 3 fits tightly with the inclined surface B8 of the inner plug 4 to prevent the inner plug 4 from moving upward when squeezed. The axial straight surface A7 of the connected tube 3 fits with the axial straight surface B9 of the inner plug 4 to prevent the inner plug 4 from tilting due to uneven force, and the straight surface and the inclined surface form an auxiliary positioning. In the process of assembling the inner plug 4 and pressing the bottle cap onto the bottle mouth, the inclined surface A6 of the connected tube 3 and the inclined surface B8 of the inner plug 4 bear pressure. At the same time, the axial straight surface A7 of the connected tube 3 and the axial straight surface B9 of the inner plug 4 assist in preventing the inner plug from tilting.

[0014] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
