Description

Combined bottle cap with plug

Technical Field

The utility model relates to a plastic bottle cap, in particular to a combined reagent bottle cap with a plug.

Background

At present, glass bottles on the market are mainly divided into high borosilicate materials, low and medium borosilicate materials and sodium calcium materials according to the materials. Mainly divided into tube-shaped bottles and molded bottles according to the process. The matched plastic bottle cap mainly comprises an anti-theft ring and a non-anti-theft ring. The plastic bottle cap with the anti-theft ring is popular because of the firm sealing, good anti-leakage and anti-theft performance, safe and convenient use, and capability of effectively preventing liquid in the bottle from being polluted by the outside. However, all the tubular glass bottles cannot be matched with the anti-theft caps, but the tubular high borosilicate glass bottles have irreplaceable functions in the application fields of chemistry, medicines and the like. The high borosilicate glass has the advantages of stronger fracture resistance, high heat-resisting temperature, capability of being used for heat-resisting equipment and the like, and particularly has great advantage in drug-acid resistance. The difference between the tube bottle and the molded bottle is that the tube bottle is more transparent than the molded bottle, the bottom of the tube bottle is thinner, the bottom of the molded bottle is thicker and less uniform, and the tube outer diameter of the tube bottle is smaller than that of the molded bottle in performance, but only the molded bottle can achieve the purpose at present. At present, domestic tube bottles can be made of high borosilicate glass materials, and most of molded bottles are made of sodium calcium materials, so that the drug resistance is inferior to that of tube bottles. Based on the advantages of the tubulation bottle such as freeze-drying, strong drug-resistant acidity, and the like, a part of high-end chemical products need to use high borosilicate packaging materials. A high borosilicate bottle without a tamper-proof cap is inferior to a tamper-proof cap bottle in sealing property and leakage-proof function.

Detailed Description

In order to make the utility model more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.

Examples

As shown in fig. 1-5, the present invention provides a combined bottle cap with a plug, which comprises a main body 1-1 of the bottle cap and a rubber plug 1-2. The rubber plug comprises a rubber plug 1-2 and is characterized in that a first convex part 1-3 is arranged on the outer edge of the middle part of the rubber plug 1-2, a second convex part 1-4 is arranged on the outer edge of the top part of the rubber plug, a first concave part 3-1 is formed between the first convex part 1-3 and the second convex part 1-4, a cavity 4-3 of a semi-closed structure is arranged on the inner side of the bottom part of the rubber plug 1-2, the cavity 4-3 is cylindrical 6-1, and the top part of the cavity 4-3 is an arc surface 4-4. The top of the rubber plug 1-2 is provided with a needle puncture guide ring 5-2. The bottle cap main body 1-1 is provided with a hollow part 5-1 matched with the rubber plug 1-2, the edge of the hollow part 5-1 is provided with a limiting convex part 4-1, the limiting convex part 4-1 is conical, when the bottle cap main body 1-1 is matched with the rubber plug 1-2, the limiting convex part 4-1 is arranged in the first concave part 3-1 and is meshed with the first concave part 3-1, and the limiting convex part 4-1 is limited between the first convex part 1-3 and the second convex part 1-4.
