Description

Technical Field

[0001] The utility model belongs to the technical field of medicine bottle caps, and particularly relates to a medicine bottle cap with a safety locking mechanism. Background Art

[0002] In the prior art, the packaging bottle of medicine consists of a bottle body and a bottle cap, and the bottle cap is movably connected to the bottle mouth by a screw thread; the combination of such a bottle cap and a bottle body has the following deficiencies: the bottle cap is relatively easy to be unscrewed from the bottle mouth, which poses a hidden danger to children. Especially when the medicine in the medicine bottle has a good taste but is not suitable for the body, children are likely to open the bottle cap and accidentally ingest it, which brings harm to the body.

[0003] According to the above, there is a prior proposal (application number: CN03258065.7, a safety cap for medicine bottle) which proposes that "when screwing the bottle cap tightly, press the outer cap by hand to make the convex clamping heads of the inner and outer caps bite, and rotate the outer cap, and the inner cap rotates accordingly", so as to achieve the effect of "children cannot easily open it, enhancing the safety of the bottle cap and ensuring the safety of medicine use".

[0004] However, according to the above-mentioned "safety cap for medicine bottle", as long as it can be pressed, it can be rotated and opened, and it is still very likely to apply pressure synchronously during rotation. Therefore, only setting this prevention structure is insufficient for the effect of safety locking. Summary of the Utility Model

[0005] (1) Technical Problems to be Solved

[0006] In order to overcome the deficiencies of the prior art, a medicine bottle cap with a safety locking mechanism is proposed to solve the problems raised in the above background art.

[0007] (2) Technical Solutions

[0008] The utility model is realized through the following technical solutions: The utility model provides a medicine bottle cap with a safety locking mechanism, including

[0009] an inner cap;

[0010] an outer cap is sleeved outside the inner cap with a gap;

[0011] a snap ring is fixedly arranged around the outer periphery of the inner cap;

[0012] a retaining ring is arranged at the bottom end of the snap ring and is fixed to the inner side of the outer cap;

[0013] one end of an elastic member is fixedly connected to the top end of the inner cap, and the other end of the elastic member is attached to the inner side of the outer cap;

[0014] a clamping block is fixedly arranged at the top end of the inner cap non - centrally, a clamping groove which can move with it is arranged above the clamping block, the clamping groove is embedded in the inner side of the outer cap or penetrates through both the inner and outer sides of the outer cap, and there is a gap between the clamping block and the clamping groove.

[0015] Furthermore, at least one set of clamping blocks is provided.

[0016] Furthermore, the outer cover is transparent.

[0017] Furthermore, anti-slip patterns are provided on the outer side of the outer cover.

[0018] Furthermore, the bottom end of the snap ring is in contact with the retaining ring.

[0019] (III) Beneficial Effects

[0020] The present utility model has the following beneficial effects compared with the prior art:

[0021] By fixedly providing a clamping block 6 at the non-centered top end of the inner cover 1, in addition to the elastic support member of the elastic member 5, a rigid support member is formed between the top end of the inner cover 1 and the inner side of the outer cover 2. At this time, the deformation of the elastic member 5 is restricted. Only when the outer cover 2 rotates outside the inner cover 1 and the clamping block 6 just appears below the card slot 7, and then a pressure is applied to the outer cover 2, the clamping block 6 will move to the card slot 7. At this time, when a rotational force is applied to the outer side of the outer cover 2, the inner cover 1 and the outer cover 2 have a combined rotational force, and then the inner cover 1 can be rotated. Therefore, in addition to the prevention by pressing, the additional corresponding structure can further enhance the anti-rotation effect and increase the ability of safety locking. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] By reading the detailed description of the non-limiting embodiments with reference to the following drawings, other features, objects, and advantages of the present utility model will become more apparent:

[0023] Figure 1 FIG. 1 is a schematic structural diagram of one embodiment of the present utility model;

[0024] Figure 2 FIG. 2 is a schematic structural diagram of another embodiment of the present utility model;

[0025] In the figure: inner cover - 1, outer cover - 2, snap ring - 3, retaining ring - 4, elastic member - 5, clamping block - 6, card slot - 7. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Please refer to Figure 1 and Figure 2 , the present utility model provides a medicine bottle cap with a safety locking mechanism, including:

[0027] An inner cover 1, with a connecting component (such as a thread, etc.) provided on its inner side;

[0028] The outer cover 2 is sleeved on the outer side of the inner cover 1 with a gap.

[0029] Among them, anti-slip patterns are provided on the outer side of the outer cover 2, increasing the friction force and facilitating the operation of rotation.

[0030] A snap ring 3 is fixedly arranged around the periphery of the inner cover 1. A retaining ring 4 is arranged at the bottom end of the snap ring 3 and is fixed to the inner side of the outer cover 2 (that is, the inner cover 1 can be supported inside the outer cover 2 through the snap ring 3).

[0031] One end of an elastic member 5 {such as a spring, an elastic sheet (plastic elastic sheet, metal elastic sheet, etc.)} is fixedly connected to the top end of the inner cover 1, and the other end of the elastic member 5 is attached to the inner side of the outer cover 2.

[0032] As shown in the figure, under the action of the above elastic member 5, the inner cover 1 and the outer cover 2 can be supported, so that the bottom end of the snap ring 3 is attached to the retaining ring 4.

[0033] A clamping block 6 is fixedly arranged at the top end of the inner cover 1 non - centrally. A clamping groove 7 that can move with it is arranged above the clamping block 6 (that is, as shown in the figure, since the outer cover 2 is axially selected inside the outer side of the inner cover 1, if the clamping block 6 is arranged in the middle of the top end of the inner cover 1 and the clamping groove 7 is correspondingly arranged in the middle of the rotation of the outer cover 2, then the function of position adjustment and pressure application is not necessary at this time).

[0034] There is a gap between the clamping block {made of a hard material (hard plastic, metal, etc.)} and the clamping groove 7 (which can ensure that the clamping block 6 does not contact the outer cover 2, reducing resistance and wear).

[0035] Please refer to Figure 1 and Figure 2 , when the clamping groove 7 is embedded in the inner side of the outer cover 2 (as Figure 1 shown), at this time, the outer cover 2 {that is, a transparent material (transparent plastic, etc.)} is transparent for observing the relative positions of the clamping block 6 and the clamping groove 7 and is more beautiful.

[0036] When the clamping groove 7 penetrates and communicates with both the inside and outside of the outer cover 2 (as Figure 2 shown), the outer cover 2 (which can be made of metal, plastic, etc.) does not need to be made of a transparent material.

[0037] Among them, at least one group of the clamping blocks 6 is provided (that is, multiple groups of clamping blocks 6 can be set).

[0038] When there is one group of clamping blocks 6, the supporting ability is poor.

[0039] When there are more than one group of clamping blocks 6, support at multiple positions can be provided, and when the outer cover 2 is pressed down, large deformation will not occur due to the materials of some manufactured outer covers 2.

[0040] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and without departing from the spirit or basic features of the present utility model, the present utility model can be implemented in other specific forms. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.

[0041] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
