Description

Bottle opener

Technical field

The utility model relates to a kind of bottle openers, more particularly to a kind of serum bottle bottle opener specialized, the bottle opener application Corkage work in serum bottle after high pressure steam sterilization under negative pressure state, operates in Biohazard Safety Equipment, can smoothly twist Corkage lid, facilitates operation.

Background technique

After general high voltage steam sterilizing, need in time to tighten serum bottle cap for use.In use, experimenter is to use Manual mode twist-off closure.It being formed in bottle due to negative pressure after cooling, bottle cap is hard to turn on, it unscrews manually very arduously, But also there is bottleneck is accidentally touched during corkage, there is microbiological contamination risk.

The lateral wall of serum bottle cap is equipped with anti-slop serrations, and main function is the frictional force enhanced when hand holds bottle cap, just In force twist-off closure.This field has not been used in the bottle opener specialized for unscrewing serum bottle cap at present.

Utility model content

The utility model is intended to provide a kind of bottle opener, can be used for the unlatching of serum bottle cap, can overcome because bearing in bottle Bottle cap caused by pressure reason is difficult to the problem of manually unscrewing, and prevents bottleneck microbiological contamination risk caused by unarmed screwing bottle cap.

In order to solve the above technical problems, the utility model provides a kind of bottle opener, including handle and the limit connecting with handle Position portion, the limiting section have circular limit hole, and the inner wall of the limit hole is equipped with limiting tooth, and the limiting tooth is along limit The fin being axially distributed in hole.

Specifically, the limiting tooth is for the anti-skidding tooth engagement with the lateral wall of serum bottle cap.

Specifically, the internal diameter of the limit hole and the outer diameter of serum bottle cap match, the limiting tooth and anti-slop serrations phase Matching.The limit hole can cover on serum bottle cap, at this time the limiting tooth and anti-skidding tooth engagement.

Specifically, the limiting tooth is uniformly distributed on the inner wall of circular limit hole.Arc between adjacent limiting tooth Length is equal.

Specifically, the limiting tooth is symmetrical relative to the center of circle of limit hole.

Specifically, the number of the limiting tooth is 4.

Specifically, the handle and be integrally formed with limiting section.

Specifically, the bottle opener uses metal material.

The bottle opener of the utility model has the characteristics that anti-slop serrations according on serum bottle cap, devises for the anti-slop serrations Bottle opener with limiting tooth, the limiting tooth can be engaged with anti-slop serrations, then held handle and had an effect rotation, and lever original is utilized Reason can open bottle cap in labour-saving very much, so that bottle cap caused by solving the problems, such as because of negative pressure reason in bottle is difficult to manually unscrew, Also bottleneck may accidentally be touched during unarmed screwing bottle cap by, which having prevented, leads to the risk of bottleneck microbiological contamination.

Detailed description of the invention

Fig. 1 is a kind of top view of specific embodiment of the bottle opener of the utility model.

Fig. 2 is the perspective view of Fig. 1.

Sign flag illustrates in attached drawing:

1 is handle；2 be limiting section；21 be limit hole；22 be limiting tooth.

Specific embodiment

Clear, complete description is carried out to technical solution of the present invention below in conjunction with attached drawing, it is clear that described implementation Example is a part of the embodiments of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, the common skill in this field Art personnel every other embodiment obtained without making creative work belongs to the model that the present invention protects It encloses.

It as shown in Figs. 1-2, is a specific embodiment of the bottle opener of the utility model.The bottle opener is by handle 1 and limit 2 two parts of position portion composition, limiting section 2 connect and are located at one end of handle 1 with handle 1.Limiting section 2 has circular limit hole 21, limiting tooth 22 is axially arranged with along limit hole 21 on the inner wall of circular limit hole 21, and limiting tooth 22 is along limit hole 21 The strip fin of axial directional distribution.

Limiting tooth 22 can with the anti-skidding tooth engagement of serum bottle cap, make limiting section 2 and the clamping of serum bottle cap and cannot Mutually displacement, then rotational handle 1, drives anti-slop serrations to make serum bottle cap with handle 1 by intermeshing limiting tooth 22 It rotates together.Handle 1 is holding tool, so as to the arm of force, convenient for having an effect, and lever principle is utilized makes to unscrew serum bottle cap Process it is very laborsaving.Accidentally touching bottleneck is easy when also avoiding unarmed twist-off closure simultaneously leads to the risk of microbiological contamination.

The internal diameter of limit hole 21 is typically provided to match with the outer diameter of serum bottle cap, and the internal diameter of limit hole 21 is slightly larger than The outer diameter of serum bottle cap enables 21 sets of limit hole on serum bottle cap, and limiting tooth 22 is and anti-skidding tooth engagement at this time.

In a preferred embodiment, limiting tooth 22 is equally distributed on the inner wall of circular limit hole 21.It is adjacent Limiting tooth 22 between arc length it is equal.For example limiting tooth 22 is two, three, four, five or more, adjacent limit Arc length between tooth 22 is equal, and the line between adjacent limiting tooth 22 constitutes regular polygon.In a preferred embodiment, it limits Position tooth 22 is symmetric relative to the center of circle of limit hole 21.As shown in Figs. 1-2, the number of limiting tooth is 4,4 limits Line between tooth constitutes a square.

As shown in Figs. 1-2, handle and be integrally formed with limiting section.In a preferred embodiment, which adopts Use metal material.

In conclusion the various embodiments described above and attached drawing are only presently preferred embodiments of the present invention, not to limit this The protection scope of invention, all within the spirits and principles of the present invention, any modification, equivalent substitution, improvement and etc. done all are answered It is included within the scope of the present invention.
