Fixing structure for bottle cap and bottle

Abstract

The invention relates to a fixing structure for a bottle cap and a bottle. The bottle comprises a bottle body, a bottleneck and a bottle opening; the bottle cap comprises an upper cap and a lower cap which are flexibly connected; the lower cap and the bottle are fixedly connected; a circle of upper convex ring and a circle of lower convex ring are arranged at the peripheral wall of the bottleneck; the lower convex ring is provided with multiple convex teeth; the lower cap comprises an inner cap and an outer cap surrounding the peripheral direction of the inner cap; the inner cap is provided with a through hole penetrating through up and down; silica gel sleeves the peripheral wall of the inner cap; the inner peripheral wall of the outer cap is provided with multiple peripherally arranged inverted buckles for being buckled below the upper convex ring and multiple peripherally uniformly arrayed fixed vertical strips for clamping the convex teeth. Compared with the prior art, the fixing in the longitudinal direction is realized by buckling the inverted buckles below the convex ring, and the convex teeth are clamped between two adjacent fixing strips to realize the fixing in the transverse direction, so the lower cap is effectively fixed on the bottleneck and the opening of the upper cap is facilitated.

Description

technical field [0001] The invention relates to the technical field of bottle caps, in particular to a fixing structure for a bottle cap and a bottle. Background technique [0002] The bottle caps of liquid condiment bottles such as soy sauce bottles and rice wine bottles mainly include: a lower cover that is threadedly connected to the neck of the bottle; There is also a set of plastic paper for sealing. When in use, just tear off the plastic paper and open the upper cover to pour out the liquid, which is very convenient. However, we often encounter such a problem during use , easy to produce looseness between the lower cover and the bottle neck, so that the liquid in the bottle flows out from the gap between the lower cover and the bottle neck, and it is easy to cause the deterioration of the liquid in the bottle, and the loosening of the lower cover will lead to the loosening of the upper cover, thus As a result, it is difficult to open the upper cover, which is very inc...

Problems solved by technology

[0002] The bottle caps of liquid condiment bottles such as soy sauce bottles and rice wine bottles mainly include: a lower cover that is threadedly connected to the neck of the bottle; There is also a set of plastic paper for sealing. When in use, as long as the plastic paper is torn off, the liquid can be poured out by opening the upper cover, which is very convenient. However, we often encounter such a problem during use , It is easy to loosen between the lower cover and the bottle neck, so that the liquid in the bottle flows out from the gap between the lower cover and the bottle neck, and it is easy to cause the deterioration of the liquid in the bottle. Moreover, the loosening of the lower cover will lead to the loosening of the upper cover, thus It is difficult to open the upper cover, which is very inconvenient
