Description

Technical Field

[0001] This utility model relates to the field of bottle technology, and more specifically to a bottle with a quick-opening cap. Background Technology

[0002] Some existing droplet bottles, such as medical eye drop bottles, need to be sealed when not in use. The seal can be opened when needed. However, the caps of existing eye drop bottles are generally screwed onto the bottle opening. There is no blocking structure at the top; the seal is achieved only by sealing the space between the cap and the bottle opening, thus isolating the bottle from the outside world. This is not a complete seal of the bottle opening, but rather a threaded seal. Due to the gaps between the threads, a complete seal cannot be achieved, resulting in limited sealing and usability. Especially during sealing, if there are contaminants in the air between the cap and the bottle opening, the bottle will become contaminated. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a bottle with a quick-opening cap. The inner cap of the bottle cap has a protruding post that extends into the vertical through hole of the vertical rod to achieve a blocking seal, which greatly improves the sealing effect. After opening the cap, the part connected by the protruding post can be directly cut off to open the seal and make it usable. It is convenient to open and close and has a good effect.

[0021] The bottle cap 20 includes an outer cap body 21 and an inner cap body 22. The inner cap body 22 is located inside the outer cap body 21. The inner cap body 22 includes a cylindrical inner sleeve portion 221. The inner side wall of the cylindrical inner sleeve portion 221 is formed with an internal thread, which is screwed onto the external thread on the outer side wall of the bottle mouth 12. The top end of the cylindrical inner sleeve portion 221 is formed with an upwardly extending conical sleeve portion 222. The vertical rod portion 31 is inserted into the conical sleeve portion 222. The bottom surface of the top plate of the conical sleeve portion 222 is formed with a protruding post 223. The protruding post 223 extends into the top of the vertical through hole 32 of the vertical rod portion 31. Its outer side wall is pressed against the top inner side wall of the vertical through hole 32. The bottom surface of the top plate of the conical sleeve portion 222 is pressed against the top surface of the vertical rod portion 31.

[0022] The inner sidewall of the top of the outer cover 21 has a plurality of vertically downward extending cut-off portions 211 formed thereon, and the bottom end of the cut-off portion 211 presses against the top surface of the middle part of the conical sleeve portion 222.

[0023] Furthermore, the conical sleeve portion 222 has a small outer diameter at the top and a large outer diameter at the bottom. The outer cover 21 includes an outer cylindrical sleeve portion 212. The top of the outer cylindrical sleeve portion 212 is formed with an upwardly extending outer conical sleeve portion 213 with a large outer diameter at the bottom and a small outer diameter at the top. The conical sleeve portion 222 is inserted into the outer conical sleeve portion 213.

[0024] Furthermore, the top inner wall of the outer conical sleeve 213 is formed with a plurality of downwardly extending cutting portions 211. In this embodiment, there are three cutting portions 211, which are evenly distributed on the top inner wall of the outer conical sleeve 213 with the vertical central axis of the outer conical sleeve 213 as the center. The cutting portions 211 are arc-shaped, and the inner wall of their bottom end is a conical wall surface, thereby greatly reducing the contact area between the bottom of the cutting portion 211 and the outer wall surface of the conical sleeve 222, and improving its cutting effect.

[0025] Furthermore, an annular protrusion limiting part 214 is formed in the middle of the inner sidewall of the outer cylindrical sleeve part 212. The top surface of the annular protrusion limiting part 214 is an upwardly inclined annular wall surface with a larger inner diameter at the top and a smaller inner diameter at the bottom. The bottom surface of the annular protrusion limiting part 214 is a downwardly inclined annular wall surface with a smaller inner diameter at the top and a larger inner diameter at the bottom. An outer annular protrusion limiting part 224 is formed on the middle and bottom outer sidewalls of the inner cylindrical sleeve part 221. The annular protrusion limiting part 214 is located between the two outer annular protrusion limiting parts 224. An inclined annular wall surface is formed on the outer side of the top of the lower outer annular protrusion limiting part 224.

[0026] Furthermore, the bottom inner wall of the outer conical sleeve portion 213 is formed with a plurality of downwardly extending protruding limiting portions 215, and the top surface of the upper outer annular protruding limiting portion 224 is formed with a plurality of upper protruding limiting portions 216, the upper protruding limiting portions 216 being located between two corresponding protruding limiting portions 215, and the top surface of the upper protruding limiting portion 216 being an inclined wall surface.

[0027] Furthermore, the drip connector 30 includes a top plate portion, the bottom surface of which is formed with a downwardly extending retaining sleeve portion, which is retained on the top inner wall of the bottle mouth 12, the bottom surface of the top plate portion is pressed against the top surface of the bottle mouth 12, and the middle of the top surface of the top plate portion is formed with an upwardly extending vertical rod portion 31, the bottom end of the vertical through hole 32 of the vertical rod portion 31 extends out of the bottom surface of the middle of the top plate portion;

[0028] A radially extending edge 229 is formed on the inner sidewall of the top end of the cylindrical inner sleeve portion 221. An upwardly extending conical sleeve portion 222 is formed on the top surface of the inner end of the radially extending edge 229. The bottom surface of the radially extending edge 229 presses against the top edge surface of the top plate portion of the drip connector 30.

[0029] In this embodiment, when not in use, the bottom of the cut-off portion 211 is in contact with the outer wall surface of the conical sleeve portion 222, such as... Figure 3 As shown, at this time, the upper protruding limiting part 216 is not between the corresponding two protruding limiting parts 215. At this time, rotating the outer cover 21 cannot drive the inner cover 22, so the bottle cap 20 cannot be rotated.

[0030] However, when needed, press down on the outer cap 21, causing the cutting part 211 to press down and cut off the corresponding position of the conical sleeve part 222. At this time, the upper protrusion limiting part 216 is between the two corresponding protrusion limiting parts 215. Then, rotate the outer cap 21 with force, and drive the corresponding protrusion limiting part 215 to rotate through the upper protrusion limiting part 216, thereby causing the inner cap 22 to rotate. When rotating, the uncut part of its conical sleeve part 222 is broken by the inserted cutting part 211 laterally squeezed. As the bottle cap 20 separates from the main bottle 10, the middle part of the conical sleeve part 222 is cut off, so that its upper part and the protrusion post 223 are on the vertical rod part 31.

[0031] Then, manually pull the protruding column 223 out of the vertical rod 31 to use it. After use, screw on the cap 20. However, the main bottle 10 is not completely sealed at this time. Therefore, the liquid in the main bottle 10 must be used up within 30 days after opening.

[0032] The above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model, and the patent protection scope of the present utility model should be defined by the claims.
