A detection sampling bottle cap and a sampling bottle

Abstract

The detection sampling bottle cap and sampling bottle of the present invention include an inner cap, an outer cap, a bottle body, and a bottle mouth, so that the inner cap and the outer cap can be tightened synchronously. After the bottle cap is tightened, the anti-retraction clamp ring and the anti-retraction ratchet teeth of the inner cap are respectively combined with the corresponding structures of the bottle mouth, and the inner cap cannot be unscrewed again without being damaged. When the sample is taken out, the integrity of the non-breaking structure of the easy-open cover of the inner cap can be used to confirm whether the sample packaging is complete and effective. The anti-theft observation area formed between the bottle cap and the bottle body can be used to observe whether the anti-theft strip at the breakpoint of the outer cap is broken and whether the sample in the bottle is leaked, etc., to ensure the authenticity of the detection, which is conducive to improving the reference value of the sampling results. It is easy to use, safe and reliable, suitable for sampling and storage of various product types, and easy to operate. The present invention provides a more comprehensive solution to ensure the convenience, accuracy and authenticity of sampling detection work.

[0046] Embodiment, a detection sampling bottle cap and sampling bottle

[0047] When in use, the outer cover 1 and the inner cover 2 cooperate with each other and can be directly screwed onto the bottle body when sealing the sample; due to the presence of the rotating latch 12, the synchronous rotation of the inner and outer covers can be ensured when the bottle cover is screwed in; when the inner cover 2 is rotated to the tightened state, the anti-retraction clamp 24 at the bottom of the inner cover will be clamped into the first anti-retraction clamp seat 33 of the bottle mouth and fit tightly, and at the same time, the anti-retraction ratchet teeth 23 on the inner cover and the anti-retraction ratchet tooth seat 32 of the bottle mouth are meshed with each other, and the inner cover cannot be rotated in the opposite direction;

[0048] When the outer cap 1 is further rotated, the second retaining ring seat 34 located at the bottle mouth can push out the rotating latch 12, causing the rotating latch break point notch 18 located on the outer cap 1 to break, and the rotating latch 12 to be separated from the bottle cap; the outer cap retaining ring 17 is engaged with the second retaining ring seat 34; at this time, the gap between the bottle cap and the bottle body will form the anti-theft ring observation area 5;

[0049] When opening, it is only necessary to rotate the outer cover 1 to open it; due to the presence of the inner cover anti-retraction ratchet teeth 23, the inner cover anti-retraction snap ring 24, the anti-retraction ratchet tooth seat 32, and the first anti-retraction snap ring seat 33 of the anti-retraction structure, the inner cover 2 will not rotate synchronously with the outer cover 1. At this time, the outer cover breakpoint anti-theft strip 16 will be stressed and broken, and the outer cover anti-retraction snap ring 17 will be left between the bottle mouth seat 35 and the second anti-retraction snap ring seat 34; further, the easy-open cover 25 is opened through the easy-open cover pull ring 252, and the sealing membrane on the sealing plug 27 containing the pierceable membrane is pierced by the detection equipment to obtain the sample in the bottle for detection. At the same time, by observing the integrity of the non-broken structure of the easy-open cover 25, it can be used to secondary confirm whether the sample packaging is complete and effective;

[0050] To sum up, the technical solution of this patent sets up multiple anti-theft structures, including secondary confirmation of whether the sample packaging is complete and effective through the integrity of the non-breaking structure of the inner cover easy-open cover, and observation of whether the anti-theft strip at the breakpoint of the outer cover is broken and whether the sample in the bottle is leaked through the anti-theft observation area formed between the bottle cap and the bottle body, which further ensures the authenticity of the detection, is conducive to improving the reference value of the sampling results, and effectively improves the convenience of sample collection and packaging, the accuracy and authenticity of transportation and storage while achieving anti-theft effects. It is easy to use, safe and reliable, and is suitable for sampling and preservation of various product types such as agricultural products and livestock products. The independent optimization design can be applied to fields with different sampling needs, which is convenient for the operation of on-site sampling personnel and ensures the integrity of the entire receiving and inspection process. It has good applicability and provides a more comprehensive solution to ensure the convenience, accuracy and authenticity of sampling and testing work.

[0051] The above describes in detail the preferred embodiments of the present invention. It should be understood that numerous modifications and variations based on the concepts of the present invention can be made by those skilled in the art without inventive effort. Therefore, any technical solution that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
