Abstract

The utility model discloses a novel bottle cap for plant tissue culture bottle whose inner edge is provided with an inner and outer screw fitted with the outer screw of bottle port. The utility model is characterized in that the top of a bottle cap is provided with an air inlet port which is corresponding to a nonwoven through hole on a plastic film which is covered on the bottle port, and the bottle cap is plastic or plastic composite material, such as PVC, PP material. The utility model has simple structure, high efficiency operation and low cost, and the utility model can be used repeatedly.

Description

The novel bottle cap that a kind of Plant Tissue Breeding bottle uses

Technical field

The utility model relates to field of plant tissue culture technique, relates in particular to the novel bottle cap that a kind of Plant Tissue Breeding bottle uses.

Background technology

Development along with modern biotechnology, tissue culture technique is increasingly extensive to be popularized, productions that moves towards the industrialization from the laboratory of more plant tissue culture technique, but as the culture bottles of a large amount of uses of tissue culture technology, because operation is loaded down with trivial details, can not adapt to industrialization operation efficiently on a large scale.

When using tradition to cover bottle,, on the plastic film that covers bottleneck, be provided with a through hole for reaching the ventilative purpose of sterilization, through hole is covered with nonwoven fabrics and with plastic film heat seal or pressing, on nonwoven fabrics, lay the number hole simultaneously; When sterilizing simultaneously, also will wrap up craft paper with rubber band outside plastic film, operate very loaded down with trivial detailsly, efficient is low, and rubber band and craft paper be easily-consumed products, the cost height; Though have the bottleneck of pair culture bottle and bottle cap position to improve, because improved plan makes Bottle cap structure become especially complicated, and cost is higher on the mould of making bottle cap and technology, though improved efficient, actual cost does not reduce.

Summary of the invention

The purpose of this utility model provides the novel bottle cap that a kind of Plant Tissue Breeding bottle uses, and has overcome the shortcoming of above-mentioned Plant Tissue Breeding bottle cap, provides a kind of and has had concurrently simple in structure and operate culture bottle bottle cap efficiently.

The novel bottle cap that a kind of Plant Tissue Breeding bottle uses, this bottle cap inner edge are provided with the internal and external threads that coincide with the bottle opening outside thread, it is characterized in that: be provided with admission port at the bottle cap top, this admission port is corresponding with the nonwoven fabrics through hole on the plastic film that covers bottleneck.

The admission port of this bottle cap can be designed to the admission port of different-diameter size according to the physiological property that group is cultivated thing, as it is big to breathe strong plant oxygen demand, and it is bigger to can be designed as diameter, and it is little to breathe weak plant oxygen demand, and it is littler to can be designed as diameter.

This bottle cap can be plastics or its composite material, as PVC, PP material.

During use, this bottle cap directly is screwed on the culture bottle bottleneck purpose of can reach the sealing sterilization, breathing freely.

The utlity model has following advantage:

1, need not outside plastic film, to wrap up craft paper, simple to operate, the efficient height.

2, simple in structure, easy to manufacture, but repeated use, and cost is low, is particularly suited for extensive sterilization treatment.

3, compare with traditional culture bottle, work efficiency provides more than 10 times, and cost reduces by 30%.

The specific embodiment

Embodiment

The novel bottle cap that a kind of Plant Tissue Breeding bottle as shown in Figure 1 and Figure 2 uses, this bottle cap 1 inner edge is provided with the internal and external threads 2 that coincide with the bottle opening outside thread, it is characterized in that: be provided with admission port 3 at the bottle cap top, this admission port is corresponding with the nonwoven fabrics through hole 5 on the plastic film 4 that covers bottleneck.

This bottle cap is PVC or PP material.

Compare with traditional culture bottle, work efficiency provides 15 times, and cost reduces by 30%.

Claims

1, a kind of novel bottle cap of Plant Tissue Breeding bottle use, this bottle cap (1) inner edge is provided with the internal and external threads (2) that coincide with the bottle opening outside thread, it is characterized in that: be provided with admission port (3) at the bottle cap top, this admission port is corresponding with the nonwoven fabrics through hole (5) on the plastic film (4) that covers bottleneck.
