Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1, the present invention provides a reagent bottle cap 100, which comprises an end 101 for closing a reagent bottle 200, wherein the end 101 is at least partially made of an elastic material, an opening area 103 is provided at a position where the end 101 is made of the elastic material, and the opening area 103 corresponds to a bottle mouth of the reagent bottle 200. Since the opening area 103 corresponds to the mouth of the reagent bottle 200, the reagent needle can enter the inside of the reagent bottle 200 after extending into the opening area 103, thereby completing the operation of sucking the reagent; meanwhile, the opening area 103 is provided at a portion where the end 101 is made of an elastic material, so that when the reagent needle is separated from the opening area 103, the opening area 103 is rebounded by its own elasticity, thereby closing the opening of the reagent bottle 200 to protect the reagent.

In a specific embodiment, the elastic material is silica gel or rubber, and the silica gel and the rubber have stable chemical properties and are not easy to influence the reagent.

Further, the reagent bottle cap 100 further comprises a side portion 102 for connecting with the reagent bottle 200, the side portion 102 being integrally formed with the end portion 103.

Wherein, optionally, the side portion 102 and the end portion 103 are integrally formed of the same material. For example, the side part 102 and the end part 103 are made of silicone, in other words, the agent bottle cap 100 is entirely made of silicone, and the structure has the advantages that the process is simple and the implementation is convenient because the same material is used for molding.

Further, it is also optional that the side portion 102 is made of plastic, and that the side portion 102 is injection molded in one piece with the end portion 101. Such as silicone and plastic, are injection molded in a single shot with the side portion 102 and end portion 10 in a special process, i.e., "two-shot molding". The advantage of this configuration is that since the side portion 102 needs to be connected to the reagent bottle 200, it requires high strength and rigidity, and thus providing it of plastic can improve the reliability of its connection to the reagent bottle 200.

In one embodiment, the open area 103 is provided at an intermediate position of the end portion 101, thereby facilitating positioning of the reagent needle.

Further, the opening area 103 is configured in a cross shape, a meter shape, or a three-pointed star shape. In the embodiment shown in fig. 1, the open area 103 is cross-shaped, i.e. it is formed by two perpendicular intersecting channels; the opening area 103 is in a shape of a Chinese character 'mi', namely, is formed by four groove bodies which are intersected at one point; the opening area 10 is a three-pointed star (i.e. shaped like a "Benz car logo"), i.e. it is composed of three grooves intersecting at the same vertex.

It is understood that the opening area 103 may have other shapes, such as an arrow shape, and the opening area 103 may be formed as long as two or more elongated grooves meet at a point or have a common intersection.

In one embodiment, the side portion 102 is provided with threads, and the side portion 102 forms a threaded connection with the reagent bottle 200. Further, in order to avoid polluting the reagent during connection, an inner thread is arranged on the inner wall of the side portion 102, and the side portion 102 is sleeved outside the reagent bottle opening and forms a threaded connection.

Further, end 101 is arranged on the side of side 102 facing away from the reagent bottle mouth. I.e. the end 101 is at its top end during use of the reagent bottle 200.

In addition, the utility model discloses still provide some other embodiments.

For example, the side portion 102 is provided with a snap ring 104, and the side portion 102 is snap-connected to the reagent bottle 200 via the snap ring 104. The end 101 may be disposed on a side of the side portion 102 away from the reagent bottle opening, or may be disposed on a side of the side portion 102 close to the reagent bottle opening.

Further, the side portion 102 and the end portion 101 are integrally formed using a silicone material.

While the invention has been described with reference to a preferred embodiment, various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In particular, the technical features mentioned in the embodiments can be combined in any way as long as there is no structural conflict. The present invention is not limited to the particular embodiments disclosed herein, but encompasses all technical solutions falling within the scope of the claims.
