Sealing bottle

Abstract

The invention provides a sealing bottle. The sealing bottle comprises a bottle cover and a bottle body, wherein the bottle cover comprises a sealing pad, inner threads and an anti-sliding groove; the bottle body comprises bottleneck outer threads, a sealing pad clamping ring and a concave part, wherein the circular sealing pad is clamped and fixed at the top end of the inner part of the bottle cover; the concave inner threads are surrounded on the inner side wall of the bottle cover; bottleneck outer threads which are screwed with the inner threads are arranged on the bottle neck outer side wall of the bottle body; a convex sealing pad clamping ring is further arranged at a position, higher than bottleneck outer threads, at the bottleneck outer side wall surrounding the bottle body; a concave part which is sunken inwards in the shape of an arc is arranged on the middle of the bottom of the bottle body; longitudinal profiles of the inner threads are rectangular; and longitudinal profiles of the bottleneck outer threads are trapezoidal. The sealing bottle has the beneficial effects that the sealing performance is good, and test paper stored inside can be completely isolated from an external environment to achieve moisture-proof effect. The sealing bottle is simple in structure and convenient in use.

Description

technical field [0001] The invention belongs to the field of sealed bottle equipment, in particular to a sealed bottle. Background technique [0002] Test paper is a "measurement ruler" used to detect solution reagents. Before the test paper is used to detect contact with the reagent, it should be kept dry and stored in a moisture-proof sealed container. Traditional sealed bottles made of plastic are usually made of The bottle cap is composed of the bottle body. The connection between the two depends solely on physical screwing, so there is a problem that the seal is not tight. Once the test paper is stored in the bottle and the environment is relatively humid, the test paper in the bottle will be damp after a long time. Can no longer detect use. Contents of the invention [0003] In view of this, the present invention aims to provide a sealed bottle with good sealing performance, which can completely isolate the test paper stored inside from the external environment, and...
