Anti-scratch aluminum anti-theft cover

Abstract

The present invention relates to a scratch-resistant aluminum anti-theft cover, comprising an aluminum outer cover and a molded inner plug mounted within the aluminum outer cover. A breaking ring is disposed at the bottom of the aluminum outer cover, and a protective ring is disposed on the outer side of the aluminum outer cover above the breaking ring. The protective ring is connected to the aluminum outer cover and disposed along the circumference of the aluminum outer cover. The diameter of the protective ring is larger than that of the aluminum outer cover. The present invention has the advantage that, because the protective ring shields the notch of the breaking ring, when a user uses the product and then twists it off, the sharp metal edges produced by the twisting will not cause scratches to the user, thereby increasing product safety and improving the user experience.

Description

Technical Field

[0001] The invention relates to an anti-scratch aluminum anti-theft cover, belonging to the field of container packaging and sealing. Background Art

[0002] The aluminum anti-theft caps currently on the market use a notch to create a connection point, connecting the top of the bottle cap to the break ring. When twisted off, the connection point breaks under the lifting force, separating the break ring from the top of the bottle cap. Other aluminum anti-theft caps retain the break ring connected to the top of the bottle cap after the connection point breaks, allowing them to be removed together when twisted off. However, a common disadvantage of both types of aluminum anti-theft caps is that both the connection point and the notch are exposed. When twisted off, the connection point creates a sharp metal edge that can easily cause scratches to the user, reducing product safety. Summary of the Invention

[0003] In order to overcome the defects of the prior art, the present invention provides an anti-scratch aluminum anti-theft cover. The technical solution of the present invention is:

[0004] The anti-scratch aluminum anti-theft cover includes an aluminum outer cover and a molded inner plug installed inside the aluminum outer cover. A breaking ring is provided at the bottom of the aluminum outer cover, and a protective ring is provided on the outside of the aluminum outer cover above the breaking ring. The protective ring is connected to the aluminum outer cover and is arranged along the circumferential direction of the aluminum outer cover. The diameter of the protective ring is larger than the diameter of the aluminum outer cover.

[0005] The protective ring is made of metal, one end of the protective ring is connected to the aluminum outer cover, and the other end extends radially outward along the aluminum outer cover to form an outer arc-shaped protrusion, and then extends innerward to the aluminum outer cover to form an inner arc-shaped protrusion. The outer edge of the inner arc-shaped protrusion contacts the outer wall of the aluminum outer cover, and the incision of the broken ring is covered in the space formed by the inner arc-shaped protrusion and the outer arc-shaped protrusion.

[0006] Several cutouts are arranged between the aluminum outer cover and the fracture ring, and all the cutouts are arranged along the circumference of the aluminum outer cover.

[0007] The incisions include long incisions and short incisions. Two long incisions are arranged between two adjacent short incisions. An incision interval is formed between the two long incisions. A connection point is formed between the long incisions and the adjacent short incisions.

[0008] There are several notch intervals and connection points, which are arranged along the circumference of the aluminum outer cover, and a notch interval is provided between two adjacent connection points.

[0009] Several vertical cuts are evenly arranged on the fracture ring. The vertical cuts are arranged along the axial direction of the fracture ring. The lower end of each vertical cut extends to the lower edge of the fracture ring, and the upper end extends to the middle of the short cut. The short cut and the corresponding vertical cut are arranged in a T-shape.

[0010] The advantage of the present invention is that due to the shielding effect of the protective ring on the incision of the broken ring, when the user uses the product and twists it off, the sharp metal edge produced by the twisting will not cause scratches to the user, thereby increasing the safety of the product and improving the user experience.

[0011] The protective ring supports the entire aluminum outer cover, which not only increases the structural strength of the aluminum outer cover, but also indirectly increases the sealing stability of the aluminum outer cover.

[0012] Since the fracture ring adopts a cracking incision, the fracture ring can be removed together with the bottle cap, which is convenient for recycling and more environmentally friendly. Moreover, since the fracture ring is removed, the sharp metal edge on the fracture ring will not cause damage to the user when using the bottle, further preventing scratches.

[0013] The protective ring covers the bottle cap cutout, thereby increasing the stability of the aluminum outer cap to a certain extent. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention will be further described below with reference to specific embodiments, and the advantages and features of the present invention will become clearer as the description proceeds. However, these embodiments are merely exemplary and do not constitute any limitation to the scope of the present invention. It should be understood by those skilled in the art that the details and forms of the technical solutions of the present invention may be modified or replaced without departing from the spirit and scope of the present invention, and such modifications and replacements fall within the scope of protection of the present invention.

[0019] See also Figures 1 to 4 The present invention relates to an anti-scratch aluminum anti-theft cover, comprising an aluminum outer cover 1 and a molded inner plug 8 installed inside the aluminum outer cover 1, a breaking ring 2 is provided at the bottom of the aluminum outer cover, and a protective ring 9 is provided on the outer side of the aluminum outer cover above the breaking ring. The protective ring is connected to the aluminum outer cover 1 and is arranged along the circumferential direction of the aluminum outer cover 1. The diameter of the protective ring 9 is larger than the diameter of the aluminum outer cover.

[0020] The material of the protective ring 9 is metal (such as aluminum), and is stretched together with the aluminum outer cover. One end of the protective ring is connected to the aluminum outer cover, and the other end extends radially outward along the aluminum outer cover to form an outer arc-shaped protrusion, and then extends to the inner side of the aluminum outer cover to form an inner arc-shaped protrusion. The outer edge of the inner arc-shaped protrusion contacts the outer wall of the aluminum outer cover, and the cut of the broken ring is covered in the space formed by the inner arc-shaped protrusion and the outer arc-shaped protrusion (the inner arc-shaped protrusion and the outer arc-shaped protrusion form a curling edge).

[0021] Several cutouts are provided between the aluminum outer cover 1 and the fracture ring 2 , and all the cutouts are provided along the circumference of the aluminum outer cover.

[0022] The incisions include long incisions 4 and short incisions 5 . Two long incisions 4 are provided between two adjacent short incisions 5 . An incision interval 3 is formed between the two long incisions 4 . A connection point 6 is formed between the long incisions 4 and the adjacent short incisions 5 .

[0023] There are several notch intervals 3 and connection points 6, which are arranged along the circumference of the aluminum outer cover 1, and a notch interval 3 is provided between two adjacent connection points 6.

[0024] Several vertical cuts 7 are evenly arranged on the breaking ring. The vertical cuts 7 are arranged along the axial direction of the breaking ring 2. The lower end of each vertical cut 7 extends to the lower edge of the breaking ring 2, and the upper end extends to the middle of the short cut 5. The short cut 5 and the corresponding vertical cut 7 are arranged in a T-shape.

[0025] The working principle of the present invention is:

[0026] (1) The aluminum outer cover rotates along the external thread at the bottle mouth under the action of external force (lifting force);

[0027] (2) The aluminum outer cover moves upward, and the fracture ring remains stationary under the constraint of the reinforcement ring at the bottle mouth;

[0028] (3) The tensile force exerted by the breaking ring on the reinforcing ring breaks the connection point between the long cut and the short cut, and the cut interval and the vertical cut are deformed (they will not be broken at this time);

[0029] (4) The aluminum outer cover continues to move upward under the action of external force. At this time, the upper end of the vertical incision is the fulcrum, and the lower end is the force point. The area from the upper end to the lower end of the vertical incision forms a force arm, and the area from the upper end of the vertical incision to the incision gap is the force arm. The incision gap is the force point. The external force continues to be applied, and this becomes a lever system. Since the force arm is much smaller than the force arm, this lever system will amplify the force of the force point at the lower end of the vertical incision by several times, greatly reducing the lifting force required to break the lower end of the vertical incision, which means that the twisting force of the bottle cap is reduced. When the lower end of the vertical incision breaks, the force arm will continue to decrease, and the entire vertical incision will continue to break until the entire vertical incision is broken. During this entire process, since the incision gap is the force point, the internal stress is small and no fracture will occur;

[0030] (5) When the vertical cut is broken, the entire fracture ring is broken, and the reinforcing ring at the bottle mouth loses its restraint on the fracture ring. Driven by the cut interval, the entire fracture ring is separated from the bottle mouth along with the bottle cap body. Among them, the protective ring (the space formed by the curling edge) shields the fracture ring cut. When the user uses the product and twists it, the sharp metal edge generated by the twisting will not cause scratches to the user, thereby increasing the safety of the product and improving the user experience.
