Abstract

The utility model relates to a ferrule for opening bottle covers, which is made of soft materials with large friction coefficient. The utility model presents an opening annular shape, the longitudinal section of the utility model presents a '7' shape, and at least a notch is arranged on the ferrule. When the ferrule is practically used, two ferrules are fetched to be respectively sheathed on a bottle bottom and a bottle cover which is tightly screwed, the bottle cover which is tightly screwed can be easily opened by hands or the bottle cover can be easily opened by the hands when the bottle cover and a bottle body are too smooth by using the larger friction between the ferrule and the bottle cover and between the ferrule and the bottle body; thus, pain and scratch of palms caused by oversize force can be avoided.

Description

The lasso that twist-off closure is used

Technical field

The utility model relates to the lasso that a kind of twist-off closure is used.

Background technology

Have the wide-mouth bottle of the used various article of placement now,, therefore twist very tightly, and the smooth of bottle and lid is difficult to make bottle cap to open, exerted oneself ambassador's palm pain even scuffing owing to require good airproof performance.

Summary of the invention

The purpose of this utility model is in order to solve the problem that bottle cap is difficult to open, a kind of lasso of twist-off closure to be provided.

The characteristics of the technical solution of the utility model are that the lasso material that friction coefficient is bigger by softness is made, and are the opening ring-type, and the vertical section is " " shape, is equipped with 1 breach on lasso at least.

The lasso made from such scheme is enclosed within the bottle cap that screws and bottle respectively at the end, with the hands twist-off closure easily.

Description of drawings

Fig. 1 is the lasso birds-eye view;

Fig. 2 is the A-A section-drawing of Fig. 1;

Fig. 3 is lasso running condition figure.

The specific embodiment

The specific embodiment of the present utility model is done an explanation in conjunction with the accompanying drawings.By Fig. 1, shown in Figure 2, lasso 1 material that friction coefficient is bigger by softness such as rubber, plastics are made, and are the opening ring-type, and the vertical section is " " shape, is equipped with 1 breach 2 on lasso at least.Breach is set can make lasso be applicable to the bottle of a certain size scope.According to the firm degree of material and the level of comfort of feel, the wall thickness of lasso is about 0.5mm.This lasso is got two of lassos when practical application, at the bottom of being enclosed within respectively bottle and on the bottle cap that screws, as shown in Figure 2.Utilize the bigger friction force between lasso 1 and bottle cap 3, the bottle 4, both hands can turn on easily revolve tension or bottle cap, the bottle cap when bottle is too sliding, like this, can avoid exerting oneself excessive and palm pain and scuffing that cause.

Claims

1. the lasso that twist-off closure is used is characterized in that, the lasso that the material that friction coefficient is bigger by softness is made is the opening ring-type, and the vertical section is " " shape, is equipped with 1 breach on lasso at least.
