Description

Anti-fake bottle cap capable of preventing secondary use

Technical Field

The utility model relates to the technical field of container covers, in particular to an anti-counterfeiting bottle cap capable of preventing secondary use.

Background

Wine bottles are generally composed of a bottle body and an anti-counterfeiting bottle cap, and the anti-counterfeiting bottle cap is generally packaged on the bottle neck of the bottle body after wine is filled in the bottle body. The prior anti-counterfeiting bottle cap generally comprises a fixing component fixed on the bottle neck, a unscrewable upper cover component and an anti-counterfeiting structure arranged between the fixing component and the upper cover component. When the bottle cap is opened for use, the anti-counterfeiting structure is damaged and cannot be repaired, so that the anti-counterfeiting purpose is achieved by destroying the bottle cap. However, since the upper cap assembly is required to satisfy both the strength requirement and the sealing requirement with the fixing assembly, the upper cap assembly is generally composed of an outer cap and an inner cap disposed in the outer cap, the outer cap is generally made of a hard material (e.g., metal or hard plastic), and the inner cap is generally made of a soft material (e.g., PE material). When the upper cover component with the structure is heated by the electric hair drier or hot water, the convex clamping structure between the inner cover and the outer cover is easy to lose efficacy, and the fixing component is easy to take down, so that the fake purpose can be achieved by recovering the bottle and the anti-fake bottle cap by an illegal person, and the anti-fake effect is not ideal.

The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model.

As shown in fig. 1, the exemplary tamper-evident bottle cap mainly comprises a fixing member for fixing to a bottle neck (not shown), an upper cap member provided to cover the fixing member, and a tamper-evident structure provided between the fixing member and the upper cap member, wherein the fixing member includes an inner body 1, an inner plug 2, and an outer body 4. The inner body 1 is cylindrical in shape as a whole, and includes a liquid outlet portion 12 and a mounting portion 11 connected from top to bottom, and an external thread 121 for connection with an upper cap assembly is provided on an outer peripheral surface of the liquid outlet portion 12. The upper section of the inner plug 2 is inserted into the liquid outlet portion 12 and is in sealing engagement with the inner wall of the liquid outlet portion 12. The lower section of the inner plug can be inserted into the bottle neck and is in sealing fit with the inner wall of the bottle neck. The outer body 4 is cylindrical, and the outer body 4 is sleeved on the mounting portion 11 of the inner body 1. The outer body 4 serves on the one hand as a decoration and on the other hand to grip the mounting portion 11 of the inner body 1, preventing the mounting portion 11 from deforming when heated.

As shown in fig. 1 to 3, the upper cap assembly includes an outer cap 6 and an inner cap 5 fixedly fitted into the outer cap 6, and an inner wall of the inner cap 5 is provided with an inner screw thread 51 engaged with an outer screw thread 121 on the inner body 1. The outer wall of the inner cover 5 is provided with a clamping groove 52, the inner wall of the outer cover 6 is provided with a clamping protrusion 61 matched with the clamping groove 52, and the clamping protrusion 61 is clamped into the clamping groove 52 to fixedly connect the inner cover 5 and the outer cover 6. Alternatively, the positions of the clamping protrusion 61 and the clamping groove 52 may be reversed, i.e. the clamping protrusion 61 is arranged on the inner cover 5 and the clamping groove 52 is arranged on the outer cover 6.

The part of the inner cover 5 provided with the clamping groove 52 is made of hard plastic, and the part of the inner cover 5 matched with the end face of the liquid outlet part is made of soft plastic. In this way, the inner cap 5 increases the connection strength with the outer cap 6 while satisfying the sealing requirement. When the electric hair drier or hot water is used for heating the upper cover assembly, the part of the inner cover 5 provided with the clamping groove 52 is not easy to deform, so that the outer cover 6 cannot be pulled out of the inner cover 5 by adopting a heating means, the clamping protrusion 61 and the clamping groove 52 can be separated only by deforming the outer cover 6 by heating, the bottle cover can be pulled out only by destroying the bottle cover, the bottle cover can be used once, the purpose of destroying the cover is achieved, the cover cannot be recycled, and the anti-counterfeiting effect is good.

In one embodiment, for convenience of processing, the inner cap 5 includes a cylinder 53 having a lower end opening and an upper end opening, and a top 54 connected to the upper end opening of the cylinder 53, the cylinder 53 is made of hard plastic, and the top 54 is made of soft plastic. As an example, the upper end surface of the cylinder 53 is closely attached to the lower surface of the top 54, so that leakage between the upper end surface of the cylinder 53 and the lower surface of the top 54 can be avoided. Since the cylinder 53 is connected with the outer cover 6 through the clamping protrusion 61 and the clamping groove 52, when the clamping protrusion 61 on the outer cover 6 is clamped into the clamping groove 52, the lower surface of the top 54 is tightly attached to the upper end surface of the cylinder 53 by the top of the outer cover 6. Alternatively, the upper end of the cylinder 53 and the top 54 are integrally formed by a two-shot molding process, so that the cylinder 53 and the top 54 are one piece, and the assembly is convenient.

In one embodiment, the barrel 53 is made of ABS plastic and the top 54 is made of PE (polyethylene) plastic.

The inner cup among the prior art adopts the injection molding to form, a mould for shaping inner cup includes fixed mold core and movable mold core, there is the cover half die cavity on the fixed mold core, the movable mold core is provided with the movable mold die cavity that corresponds with the cover half die cavity, when cover half and movable mold compound die, form between movable mold die cavity and the cover half die cavity and be used for shaping inner cup die cavity, during the drawing of patterns, the movable mold core forces to pull out from the inner cup, consequently, the gradient (the inclination of the upside inclined plane and the perpendicular line of degree of depth) of the screw thread of the internal screw thread of current inner cup can not be too little, about 40 degrees, the height of screw thread can not be too high, generally about 0.7 mm. When the outer cover is pulled out by force, the internal thread on the outer cover and the external thread on the inner cover are easy to fail, and the outer cover can drive the inner cover to be separated from the liquid outlet part, so that the anti-counterfeiting effect is poor. In one embodiment, as shown in fig. 4, the inclination α of the upper inclined surface of the thread of the female screw 51 is 20 to 30 degrees. The height H of the screw thread is 0.8-1.2 mm. The inner cover 5 with the structure is demolded in a rotary demolding mode, so that the production is met, and meanwhile, a good anti-counterfeiting effect is achieved.

In one embodiment, the lower surface of the top portion 54 has a downwardly extending sealing ring 55, which sealing ring 55 is adapted to be in intimate contact with the spout portion 12 when the closure is fully screwed on, and which sealing ring is made of a soft plastic. The sealing ring provides good sealing performance and prevents liquid leakage.

The anti-counterfeiting structure in this embodiment includes anti-counterfeiting teeth (not shown in the figure) disposed on the outer cover 6 and a cam disposed on the outer body 4, when the anti-counterfeiting structure is opened and used, the outer cover 6 is rotated to drive the cam to rotate, the cam breaks the anti-counterfeiting teeth, and the anti-counterfeiting teeth cannot be repaired after being twisted off, thereby achieving the anti-counterfeiting purpose.

The foregoing examples illustrate only a few embodiments of the utility model and are described in detail herein without thereby limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model.
