CN202244521U - Bottle cap for liquid reagent bottle - Google Patents

Abstract

The utility model discloses a bottle cap for a liquid reagent bottle. The bottle cap is a plastic bottle cap with a round mouth; the inner side wall of the bottle cap is provided with an internal thread which is matched with a bottleneck of the reagent bottle; a gasket is arranged in the bottle cap, and clings to the inner top end of the bottle cap; and a plurality of vertical bar bumps are arranged at intervals on the side wall of the bottle cap. In the bottle cap, the gasket is adopted, so that the combination between the bottle cap and the bottleneck can be enhanced, the bottle cap can be protected, and the phenomenon of cracking or corrosion of the bottle cap caused by a pressure in the bottle is avoided; and the friction force during rotation of the bottle cap can be enhanced by arranging the vertical bar bumps, so that the sealing property of the bottle cap on the bottleneck is ensured.

Description

The liquid reagent bottle cap

Technical field

The utility model relates to bottle cap, more particularly, relates to a kind of liquid reagent bottle cap.

Background technology

In the required reagent of colleges and universities and scientific research institutions, major part is liquid, need use glass bottle.For the sealing that solves this kind product is preserved; Prevent in long-term storage, to cause destruction to the bottle cap sealing effect because of liquid corrosion property in pressure of the inside of a bottle or the bottle; Simultaneously for strengthening the aesthetics of packing; Must design again and improve existing bottle cap, to satisfy the bottled sealing demand of liquid reagent.

The utility model content

To the above-mentioned shortcoming that exists in the prior art, the purpose of the utility model provides a kind of liquid reagent bottle cap, in order to realize the strict seal to bottleneck, prevents the bottle cap cracking to occur because of pressure of the inside of a bottle.

For realizing above-mentioned purpose, the utility model adopts following technical scheme:

This liquid reagent bottle cap is a round mouth shape plastic bottle closure; The bottle cap madial wall is provided with and the suitable negative thread of reagent bottle bottleneck; Be provided with a pad in the described bottle cap, pad is close to the bottle cap inner tip, and on the bottle cap sidewall, also is interval with several vertical bar projections.

Be connected between described bottle cap sidewall and the top and be the radian shape.

Described bottle cap sidewall bottom inner ring is provided with dentation.

In technique scheme; The liquid reagent bottle cap of the utility model is a round mouth shape plastic bottle closure; The bottle cap madial wall is provided with and the suitable negative thread of reagent bottle bottleneck; Be provided with a pad in the described bottle cap, pad is close to the bottle cap inner tip, and on the bottle cap sidewall, also is interval with several vertical bar projections.Not only can strengthen combining of bottle cap and bottleneck through pad; Can play a protective role to bottle cap again; Prevent bottle cap cracking to occur or corroded, can strengthen the friction force when the rotation bottle cap through the vertical bar projection is set, to guarantee the leak tightness of bottle cap to bottleneck because of pressure of the inside of a bottle.

Description of drawings

Fig. 1 is the scheme drawing of the bottle cap of the utility model;

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

The specific embodiment

Further specify the technical scheme of the utility model below in conjunction with accompanying drawing and embodiment.

See also Fig. 1～shown in Figure 2, the liquid reagent bottle cap 1 of the utility model is basic identical with prior art, equally also is round mouth shape plastic bottle closure; Bottle cap 1 madial wall is provided with the negative thread 2 suitable with the reagent bottle bottleneck, and different is to be provided with a pad 3 in the described bottle cap 1; Pad 3 is close to bottle cap 1 inner tip, when bottle cap 1 spiral cover to bottleneck, can strengthen combining between bottle cap 1 and the bottleneck through pad 3; Play the effect of strict seal; But also can prevent that liquid from directly contacting with bottle cap 1, avoid because of the corrosion that bottle cap 1 ftractures or receives liquid appears in pressure of the inside of a bottle, thereby protected bottle cap 1 to be without prejudice.And on bottle cap 1 sidewall, also be interval with several vertical bar projections 4,, can guarantee the leak tightness of 1 pair of bottleneck of bottle cap to strengthen the friction force when rotating bottle cap 1; Inner ring is provided with dentation 5 in bottle cap 1 sidewall bottom, between bottle cap 1 sidewall and top, is connected and is the radian shape, so, not only can strengthen the binding force of bottle cap 1 and bottleneck, and has strengthened the aesthetics of bottle cap 1 own.

The bottle cap 1 of the utility model can adopt the mould one-shot forming to make, and guaranteeing its specification and quality, and strengthens its intensity, except being applicable to the liquid reagent bottle, can also be applicable to the bottle of other different occasions.

Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the utility model; And be not the qualification that is used as the utility model; As long as in the connotation scope of the utility model, all will drop in claims scope of the utility model variation, the modification of the above embodiment.

Claims (3)

1. a liquid reagent bottle cap is round mouth shape plastic bottle closure, and the bottle cap madial wall is provided with and the suitable negative thread of reagent bottle bottleneck, it is characterized in that:

Be provided with a pad in the described bottle cap, pad is close to the bottle cap inner tip, and on the bottle cap sidewall, also is interval with several vertical bar projections.

2. liquid reagent bottle cap as claimed in claim 1 is characterized in that:

Be connected between described bottle cap sidewall and the top and be the radian shape.
