Description

Technical Field

[0001] The utility model belongs to the field of bottle cap production, and particularly relates to an environmentally friendly bottle cap and a mold for forming the environmentally friendly bottle cap. Background Art

[0002] Bottle caps are common in everyday life. They seal a wide variety of bottles, including beverage bottles, health supplement bottles, and medicine bottles. Traditional mineral water and cola bottles require the caps to be detached from the bottle when opening. This inconvenience is compounded by the fact that the caps must be held in your hand or placed elsewhere. Furthermore, once detached, they are easily lost. This not only makes it difficult to carry the bottles, but also hinders centralized recycling and is unsuitable for environmental protection. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides an environmentally friendly bottle cap and a mold for forming the environmentally friendly bottle cap.

[0006] Preferably, longitudinal first fractures are provided between the two sides of the connecting belt and the flip cover; the first fractures are communicated with the tearing opening.

[0007] Preferably, a groove is provided on the inner side of the connecting belt.

[0008] Preferably, a second longitudinal fracture is provided between the two sides of the connecting belt and the flip cover; the second fracture is connected to the tearing hole; a third transverse fracture is provided between the two sides of the top of the connecting belt and the flip cover; the third fracture is connected to the second fracture.

[0009] Preferably, fourth longitudinal fractures are symmetrically provided on both sides of the bottom of the connecting belt, and the fourth fractures are connected to the buffer cracks; fifth transverse fractures are symmetrically provided on both sides of the bottom of the connecting belt, and the fifth fractures are connected to the fourth fractures.

[0010] Preferably, a buffer tearing strip is provided between the upper and lower walls of the buffering crack.

[0011] Preferably, the inner top wall of the flip cover is provided with an inner plug cover.

[0012] The mould of the present invention is to mould the mould base of described mould base, and the mould base of described mould base is to mould the mould base of described mould base, and the mould base of described mould base is to mould the mould base of described mould base.

[0013] Preferably, the outer side of the middle mold sleeve is correspondingly provided with structures for forming the internal thread, the anti-slip convex ring, the tearing opening, the easy-tear band and the buffering crack.

[0014] The beneficial effects of the utility model are:

[0015] 1. The environmentally friendly bottle cap proposed by the utility model adopts a flip-top structure design. When the bottle cap is opened, the cap base and the bottle are connected, which will not cause the bottle cap to separate from the bottle, resulting in the phenomenon of losing the bottle cap or throwing it away at will.
