[0002] In the packaging process of biological, pharmaceutical, chemical and other reagents or medicines, packaging bottles for storing reagents or liquids are necessary and frequently used. Packaging bottles can store reagents or liquids in a sealed manner to prevent the reagents or liquids from being exposed to the air and causing the risk of contamination of the reagents or liquids.

[0003] In order to achieve a good sealing effect, the commonly used packaging bottles on the market generally have a structure that includes two main parts: a bottle body and a bottle cap. The inner surface of the bottle cap is provided with threads, and the outer surface of the bottle mouth of the bottle body is provided with threads. The bottle cap and the bottle body are connected by threads. However, this threaded connection between the bottle cap and the bottle body is not conducive to the sealing of the liquid in the bottle, and the vibration during transportation or unintentional slight rotation can easily cause the bottle cap to loosen, resulting in the loss or deterioration of the liquid in the bottle. For reagents or liquids that require higher sealing and isolation requirements, the use of such packaging bottles is very unfavorable for the storage of reagents or liquids. It is urgent to improve the packaging bottles to meet higher sealing requirements. Utility Model Content

[0004] Therefore, the technical problem to be solved by the utility model is to overcome the problem in the prior art that the traditional packaging bottle in which the bottle cap and the bottle body are screwed together by threads cannot meet the higher storage sealing requirements and there are certain risks during use.

[0005] To solve the above technical problems, the utility model provides a strip-blocking protective puncture bottle cap, comprising: a bottle cap body, one end of which is provided with an indented cavity, a puncture needle is provided on the bottom surface of the cavity, and the puncture needle is used to puncture the sealed bottle body, the two ends of the bottle cap body in the axial direction are respectively a first end and a second end, the first end is an end of the bottle cap body close to the bottle body after the bottle cap body is sleeved onto the bottle body, and a step is provided on the outer wall of the first end; a blocking strip, which is sleeved on the outside of the first end, and the blocking strip is arranged between the first end and the bottle body, and when the bottle cap body and the bottle body are screwed, the blocking strip is used to prevent the puncture needle from contacting the sealing portion of the bottle body.

[0006] In one embodiment of the utility model, the barrier strip is in the shape of a rectangular strip, and a through hole 1 and a locking protrusion are respectively provided at both ends of the barrier strip in the length direction, and the locking protrusion is placed in the through hole 1 to allow the barrier strip to surround in a ring shape.

[0007] In one embodiment of the present invention, when the barrier band is in a ring shape, one end of the barrier band close to the bottle cap body is the third end, and one end of the barrier band close to the bottle body is the fourth end.

[0008] In one embodiment of the present invention, the fourth end contacts the outer wall of the bottle body to prevent the puncture needle from contacting the sealing portion of the bottle body.

[0009] In one embodiment of the utility model, a connecting piece is provided between the step 1 and the third end, the blocking belt is flexibly connected to the bottle cap body via the connecting piece, and the connecting piece is used for the blocking belt to flip around the bottle cap body.

[0010] In one embodiment of the present invention, when the blocking belt is in a ring shape, a plurality of grooves are provided on the outer wall of the blocking belt.

[0011] In one embodiment of the utility model, a first thread is provided on the inner wall of the cavity, a second thread is provided on the outer wall of the bottle mouth of the bottle body, and the first thread and the second thread are threadedly connected.

[0012] In one embodiment of the present invention, an anti-slip edge is provided on the outer wall of the bottle cap body.

[0013] In an embodiment of the present invention, the first through hole is a circular hole, and the locking protrusion is a truncated cone.

[0014] In one embodiment of the present invention, the end of the puncture needle opposite to the bottle body is configured to be a conical sharp corner.

[0015] The above technical solution of the utility model has the following beneficial effects compared with the prior art:

[0016] The strip-barrier protection puncture bottle cap described in the utility model can be turned over at a certain angle and then formed into a circle and arranged between the bottle cap body and the bottle body. In this way, during the process of screwing the bottle cap, the lower end surface of the bottle cap body will abut against the barrier band, so that the bottle cap body can no longer move downward, thereby protecting the puncture needle in the bottle cap body from puncturing the bottle body. When the user wants to use it, he needs to unscrew the bottle cap body, untie the barrier band, and tear off the barrier band or turn the barrier band 90 degrees and then tighten the bottle cap body. At this time, there is no resistance force, and the puncture needle in the bottle cap body can puncture the bottle. In the case of high storage sealing requirements, the bottle body can be completely sealed, and the bottle body can be conveniently opened by the arranged puncture needle.

DETAILED DESCRIPTION

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0024] Reference Figure 1-4 As shown, the strip-barrier protection puncture bottle cap of the utility model comprises: a bottle cap body 1 and a barrier strip 2; the bottle cap body 1, one end of which is provided with a recessed cavity 11, and a puncture needle 12 is provided on the bottom surface of the cavity 11, and the end of the puncture needle 12 opposite to the puncture part 421 is set to a conical sharp angle, and the puncture needle 12 is used to puncture the sealed bottle body, and the two ends of the bottle cap body 1 in the axial direction are respectively a first end 13 and a second end 14, the first end 13 is an end of the bottle cap body 1 close to the bottle body after being sleeved on the bottle body, and a step 15 is provided on the outer wall of the first end 13; the barrier strip 2 is sleeved outside the first end 13, and the barrier strip 2 is arranged between the first end 13 and the bottle body, and when the bottle cap body 1 is screwed with the bottle body, the barrier strip 2 is used to prevent the puncture needle 12 from contacting the sealing part of the bottle body.

[0025] like Figure 3As shown, the barrier strip 2 is in the shape of a rectangular strip, and a through hole 21 and a locking protrusion 22 are respectively provided at both ends of the length direction of the barrier strip 2, the through hole 21 is a round hole, and the locking protrusion 22 is a truncated cone. The locking protrusion 22 is placed in the through hole 21 for the barrier strip 2 to be surrounded in a ring shape. When the barrier strip 2 is surrounded in a ring shape, the end of the barrier strip 2 close to the bottle cap body 1 is the third end 23, and the end of the barrier strip 2 close to the bottle body is the fourth end 24. The fourth end 24 contacts the outer wall of the bottle body to prevent the puncture needle 12 from contacting the sealing portion of the bottle body.

[0026] like Figure 3 As shown, under normal circumstances, the barrier belt 2 is in the position indicated by the arrow C, and the fourth end 24 is against the shoulder of the bottle body, so that when the bottle cap body 1 and the bottle body are screwed, the puncture needle 12 cannot touch the sealing part on the bottle body due to the obstruction of the barrier belt 2, which can prevent the puncture needle 12 from puncturing the sealing part by mistake; the locking protrusion 22 is pulled out from the through hole 1 21, and the barrier belt 2 is unfolded into a strip. When the barrier belt 2 is in the position indicated by the arrow B, the barrier belt 2 is opened, and the barrier belt 2 is moved out from the position between the bottle cap body 1 and the bottle body. At this time, there is no obstruction of the barrier belt 2, and the bottle cap body 1 and the bottle body are rotated. The rotating bottle cap body 1 can move toward the bottle body, so that the puncture needle 12 punctures the sealing part.

[0027] In the above structure, a connecting piece 3 is provided between the step 15 and the third end 23, and the blocking strip 2 is flexibly connected to the bottle cap body 1 through the connecting piece 3, and the connecting piece 3 is used for the blocking strip 2 to turn around the bottle cap body 1. For example, the connecting piece 3 can be connected by a thin piece of plastic, and when opening the connecting piece 3, the connecting piece 3 can be torn off or bent to move the blocking strip 2 out from between the bottle cap body 1 and the bottle body.

[0028] In the above structure, in order to facilitate the bending of the barrier belt 2 so that the barrier belt 2 is bent into a ring shape, when the barrier belt 2 is formed into a ring shape, a plurality of grooves 25 are provided on the outer wall of the barrier belt 2. The plurality of grooves 25 reduce the hardness of the barrier belt 2 and facilitate bending.

[0029] In the above structure, the inner wall of the cavity 11 is provided with a thread 111, and the outer wall of the bottle mouth of the bottle body is provided with a thread 2, and the thread 111 and the thread 2 are threadedly connected. After the packaging bottle is used normally, the bottle body has been punctured by the puncture needle 12, and later, the bottle cap body 1 and the bottle body only need to be connected by a threaded connection, so that they can be opened and used at any time. In order to facilitate the screwing of the bottle cap body 1, a plurality of anti-slip edges are provided on the outer wall of the bottle cap body 1.

[0030] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods.
