DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figures 1 to 6 In an embodiment of the present invention, a bottle cap for a bottled insulin injection comprises a T-shaped rubber stopper 1, a top outer side of the T-shaped rubber stopper 1 is provided with a protective component 3, and the protective component 3 comprises an installation unit, a protective unit, and a disassembly unit;

[0031] The mounting unit is used to fix the T-shaped rubber stopper 1 to the mouth of the insulin bottle;

[0032] The protection unit, the disassembly unit and the installation unit are assembled as a whole to achieve shielding and protection of the top surface of the T-shaped rubber plug 1;

[0033] The downward disassembly unit is used to unlock the protection unit and the installation unit, so as to realize the convenient disassembly of the protection unit;

[0034] The mounting unit includes a press-fit ring 301, a concave clamping portion 302, and a compression shrinking edge 303;

[0035] An annular groove 2 is formed on the outside of the large diameter portion of the top of the T-shaped rubber stopper 1, and a concave clamping portion 302 is formed in the middle of a press-fitting ring 301. The press-fitting ring 301 covers the outside of the large diameter portion of the top of the T-shaped rubber stopper 1 and is clamped to the inner side of the annular groove 2 through the concave clamping portion 302.

[0036] The bottom of the press-fit ring 301 extends to below the large diameter portion of the top of the T-shaped rubber stopper 1. The compression shrinkage edge 303 is formed on the bottom of the press-fit ring 301 to form a compression effect with the annular raised edge of the insulin bottle mouth;

[0037] The protection unit includes an outer protection cover 306 and an annular contraction portion 307;

[0038] The press ring 301 is provided with a plurality of annularly distributed notched grooves 304 at the position of the concave clamping portion 302, and an arc-shaped protrusion 305 is formed at the position of the press ring 301 corresponding to the notched grooves 304. The outer surface of the arc-shaped protrusion 305 protrudes from the outer side of the press ring 301;

[0039] The annular contraction portion 307 is formed in the middle of the vertical portion of the outer protective cover 306. The outer protective cover 306 is sleeved on the outside of the press-fit ring 301 and is clamped with the arc-shaped protrusion 305 through the annular contraction portion 307 to achieve relative fixation between the outer protective cover 306 and the T-shaped rubber stopper 1.

[0040] The disassembly unit includes an inner protective cover 308 and a circular film 310;

[0041] The inner protective cover 308 is located inside the outer protective cover 306, and the outer protective cover 306 is sleeved with the outer side of the upper portion of the press-fitting ring 301, so that the upper surface of the T-shaped rubber stopper 1 is shielded and protected by the inner protective cover 308 and the outer protective cover 306;

[0042] A central hole slot 309 is formed in the middle of the top of the outer protective cover 306. The outer edge of the circular film 310 is bonded and fixed to the inner side of the central hole slot 309. The lower surface of the middle portion of the circular film 310 is bonded and fixed to the middle of the top of the inner protective cover 308. When the circular film 310 is pressed, the inner protective cover 308 moves downward to squeeze the arc-shaped protrusion 305 to deform, thereby releasing the engagement between the arc-shaped protrusion 305 and the annular contraction portion 307.

[0043] The inner diameter of the protective cover 308 matches the outer diameter of the press-fitting ring 301, the inner wall diameter of the outer protective cover 306 above the annular contraction portion 307 matches the outer diameter of the inner protective cover 308, and the inner wall diameter of the outer protective cover 306 below the annular contraction portion 307 matches the outer diameter of the press-fitting ring 301.

[0044] In this embodiment, when using this bottle cap, the operating steps are as follows:

[0045] First, assemble the press ring 301 with the T-shaped rubber stopper 1. At this time, the compression shrinkage edge 303 on the press ring 301 has not yet been formed. Then, assemble the T-shaped rubber stopper 1 with the insulin bottle 4, so that the small diameter portion of the bottom of the T-shaped rubber stopper 1 is inserted into the interior of the insulin bottle 4, and the large diameter portion of the top of the T-shaped rubber stopper 1 is in contact with the top of the insulin bottle 4. Then, by forming the compression shrinkage edge 303 on the bottom of the press ring 301, it is aligned with the annular raised edge on the outside of the bottleneck of the insulin bottle 4 (the shape of the insulin bottle 4 is as shown in FIG. 1 ). Figure 6 ) to form a press-fit fixing effect;

[0046] Afterwards, the outer protective cover 306 and the inner protective cover 308 can be integrally sleeved with the press-fitting ring 301. During this process, the bottom edge of the outer protective cover 306 can squeeze the arc-shaped protrusion 305 to shrink it to the inside of the concave clamping portion 302, so that the bottom edge of the outer protective cover 306 can smoothly pass through the area where the arc-shaped protrusion 305 is located. When the annular contraction portion 307 on the outer protective cover 306 is aligned with the arc-shaped protrusion 305, the arc-shaped protrusion 305 pops out under the action of its own elastic force and snaps into the annular contraction portion 307, thereby achieving relative fixation of the outer protective cover 306 and the press-fitting ring 301. At the same time, the top of the inner wall of the inner protective cover 308 is in contact with the upper surface of the T-shaped rubber stopper 1, and the shielding protection of the upper surface of the T-shaped rubber stopper 1 is completed.

[0047] When it is necessary to extract the liquid medicine, two fingers pinch the outer protective cover 306, and one finger presses the circular film 310 area. This pressing force can move the inner protective cover 308 downward and squeeze the T-shaped rubber plug 1 to deform. As the inner protective cover 308 moves downward, its bottom edge contacts and squeezes the arc-shaped protrusion 305, causing the arc-shaped protrusion 305 to shrink a part toward the inside of the concave clamping portion 302. At this time, the clamping area of ​​the arc-shaped protrusion 305 and the annular contraction portion 307 is reduced. At the same time, an upward pulling force is applied to the outer protective cover 306, causing the annular contraction portion 307 to further squeeze the arc-shaped protrusion 305, causing the arc-shaped protrusion 305 to completely shrink to the inside of the concave clamping portion 302, and then the outer protective cover 306 is tightened. The cover 306 can be smoothly moved upward (it should be noted that when the outer protective cover 306 moves upward to squeeze the arc-shaped protrusion 305 and it is completely retracted, the pressure on the inner protective cover 308 can be stopped. At this time, the inner protective cover 308 will move upward and reset under the action of the restoring elastic force of the T-shaped rubber plug 1 and the circular film 310, and then move upward together with the outer protective cover 306), thereby achieving the effect of removing the outer protective cover 306 and the inner protective cover 308 as a whole. At this time, the upper surface of the T-shaped rubber plug 1 is exposed to the outside, which makes it easier to extract the liquid medicine. The structure in which the inner protective cover 308 moves downward to squeeze and contract the arc-shaped protrusion 305 can reduce the resistance when the outer protective cover 306 moves upward, making it easier to remove the outer protective cover 306.

[0048] After the operation of extracting the liquid medicine is completed, the outer protective cover 306 and the inner protective cover 308 can be connected and fixed to the press ring 301 again. The overall operation is simple and convenient.

[0049] Please refer to Figures 2-3 The inner diameter of the press-fitting ring 301 matches the outer diameter of the large diameter portion of the top of the T-shaped rubber plug 1 , and the top level of the press-fitting ring 301 is lower than the top upper surface level of the T-shaped rubber plug 1 .

[0050] In this embodiment, the top of the T-shaped rubber plug 1 protrudes from the top of the press-fitting ring 301, thereby providing deformation space for the inner protective cover 308 to move downward and squeeze the T-shaped rubber plug 1.

[0051] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
