The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. The term "or/and" as used herein includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 to 5, a chemical agent integrated cap provided in the present embodiment includes an outer cap 1 and an inner plug 2. One end of the outer cover 1 is provided with an end cover 11, and the other end is an opening. The opening is used for covering the bottle mouth of the bottle and is screwed and fixed with the bottle mouth through the internal thread arranged in the outer cover 1. Compared with the prior art, the method is characterized in that: in this embodiment, four cards 12 for limiting the position of the inner plug 2 are fixedly connected to the end of the inner wall of the outer cover 1 near the end cover 11. The four cards 12 are evenly distributed in a ring shape around the center of the outer cover 1. The inner plug 2 then comprises a plug body 21 and a brim 22. The plug body 21 is composed of two sections of plug bodies 21 with different diameters, and the two sections of plug bodies 21 are connected through a transition surface 23. Wherein one end of the larger diameter plug 21 is fixedly connected concentrically with the brim 22. The transition surface 23 connecting the two segments 21 is provided as an inclined surface (the transition surface 23 is formed in a truncated cone shape around as a whole). The design of the upper wide and lower narrow and transition surface 23 allows the inner plug 2 to be easily pressed into the bottle mouth and ensures sealing performance.

The outer cap 1 and the inner plug 2 are separate units prior to use, which is convenient to manufacture and easy to use. In use, as shown in fig. 2, the brim 22 will eventually be disposed between the card 12 and the end cap 11 on the outer cover 1. As shown in fig. 3, in this embodiment, the spacing between the end cap 11 and the card 12 on the outer cap 1 is exactly the thickness of the brim 22 and is a tight fit. I.e. the brim 22 is combined with the outer cap 1, the brim 22 is deformed at the edge so that it enters between the card 12 and the end cap 11, and the inner plug 2 is integrated with the outer cap 1 to form an integrated cap according to the present utility model.

The chemical reagent integrated cover is formed by clamping the inner plug 2 in the outer cover 1 to form a whole before use. When the bottle is used, a line worker directly aligns the outer cover 1 to the bottle mouth for screwing, and in the screwing process, the inner plug 2 is slowly pressed into the bottle mouth by the outer cover 1. When a consumer is in the opening process, the outer cover 1 is directly unscrewed, and the inner plug 2 is pulled out of the bottle opening through the card 12 in the process that the outer cover 1 is far away from the bottle opening. Compared with the traditional mode of manually taking out the inner plug 2 from the bottle mouth, the integrated cover provided by the utility model can not shake violently when the bottle is opened, so that reagent liquid in the bottle is prevented from splashing to eyes or skin, potential safety hazards are greatly reduced, and the bottle is more convenient. Meanwhile, the integrated cover designed by the utility model is originally used on a full-automatic production line of chemical reagents, so that a great deal of manpower is saved, the production efficiency is improved, and the integrated cover is worthy of popularization.

The integral cover of the present utility model is also designed primarily for some of its dimensions and technical parameters.

In this embodiment, the thickness of the brim 22 is optimally designed to be 2mm. When the thickness design is less than 1.5mm, the cap rim 22 is not strong enough due to the thinness, and the inner plug 2 is generally tight when being plugged in the bottle mouth in order to ensure tightness, so that when the integrated cover is repeatedly used, the inner plug 2 is sometimes separated from the outer cover 1, thereby failing to completely meet the requirement of the integrated cover. While the thickness of the brim 22 is adjusted to 2mm, the strength thereof is improved, but four cards 12 may be crushed when the brim 22 enters the outer cover 1. For this purpose, as shown in fig. 5, a chamfer (R-angle in the figure) with a radius of 1.5mm is provided on the side of the outer edge of the brim 22 facing the end cap 11, the opposite end facing away from the end cap 11 being an equal diameter cylindrical surface, and the equal diameter cylindrical surface and the chamfer each occupying half the height on the end face of the brim 22. The shape of the card 12 is set to be circular arc shape with the same radian as the inner diameter of the outer cover 1, the length of the card 12 extending from the inner wall of the outer cover 1 to the center of the outer cover 1 is 1mm, the diameter of the brim 22 is matched with the inner diameter of the outer cover 1 (namely, clearance fit is formed between the diameter of the brim 22 and the inner diameter of the outer cover 1), and the technical parameter design can effectively clamp the main brim 22 so as not to separate from the main brim, and the card 12 is not broken by pressing the brim 22 when the brim 22 is plugged due to overlong. The provision of the chamfer on the mating brim 22 allows the inner plug 2 to be conveniently and quickly integrated with the outer cap 1 for use. The combination test of the inner plug 2 and the outer cap 1 was performed according to the dimensions and technical parameters described above: the tightness of the inner plug 2 is set at-30 KPa for vacuum air pressure test, which accords with the national detection standard. At the same time, the outer cover 1 is repeatedly opened on the bottle mouth for more than 50 times, and the inner plug 2 does not fall on the outer cover 1.

In another embodiment, the length of the card 12 is constant, but it is disposed obliquely toward one side of the end cap 11 (i.e., the end of the card 12 not connected to the outer cap 1 is disposed near the end cap 11). The card 12 is set to have an inclination of 5 °, so that when the chamfer interacts with the inclined card 12, the brim 22 is more easily introduced between the card 12 and the end cap 11, and the inclined card 12 abuts against the brim 22, so that the card 12 is less likely to come out and break.

The chemical reagent integrated cover provided by the utility model is suitable for corrosive chemical reagent liquid or pesticides. As the inner plug 2 is directly contacted with chemical products, LDPE (low density polyethylene) with the anticorrosion performance of 2426k model is adopted as the material. The inner plug 2 is provided with a hollow structure with one open end for saving materials and improving production efficiency. The opening end of the plug body 21 is arranged close to the cap edge 22, and the other end is a closed end and is used for extending into the bottle mouth to seal. As shown in fig. 4, the outer cap 1 is made of common PE or PP, is flexible and strong when screwed on the bottle mouth, and is convenient to open and recycle while the inner plug 2 is pressed tightly. The outer wall of the outer cover 1 is provided with anti-skid patterns, so that the rotary operation is convenient. Since the raw material properties of the outer cap 1 and the inner plug 2 are completely different, they are directly produced as two products separately. The two products produced separately are assembled into an integrated cover on a full-automatic visual inspection assembly line, so that the process design is facilitated and the yield is improved.

In another embodiment, referring to fig. 1 and 2, compared with the above embodiment, the integrated chemical reagent cap is further designed with an anti-counterfeiting structure according to the bottle opening requirement. The security structure comprises a housing 3 and four security blocks 4. The housing 3 is a ring, and one side section of the ring isType (2). The housing 3 is concentrically fixed to the open end of the outer cap 1 and has a diameter larger than that of the outer cap 1. Four mounting holes are formed in the housing 3, and an anti-counterfeiting block 4 is arranged in each mounting hole. In particular, the tamper proof mass 4 comprises a connection block, ratchet teeth and frangible connection. The connecting block is located in the mounting hole, and one end of the connecting block is provided with a ratchet. The ratchet faces the axis of the outer cover 1, the tooth direction of the ratchet is the screwing direction of the outer cover 1 (the tooth direction is the direction in which the ratchet is not stressed), and the counter tooth direction is the opening direction of the outer cover 1 (the counter tooth direction is the direction in which the ratchet is stressed). The other end of the connecting block is connected with the breakable connecting piece. The frangible connection is formed of an elongated plastic strip that breaks when subjected to a relatively large external force. The other end of the frangible connection is fixedly connected to the housing 3 such that the anti-counterfeiting block 4 is retained in the mounting hole.

The bottle mouth matched with the chemical reagent integrated cover is provided with a stop bar which is arranged in the vertical direction and corresponds to the anti-counterfeiting structure. When the outer cover 1 is completely screwed on the bottle mouth, the outer cover 1 presses the inner plug 2 to seal the bottle mouth. Simultaneously, the ratchet is continuously contacted with the barrier strip, and the anti-counterfeiting block 4 does not generate larger acting force with the barrier strip until the outer cover 1 is screwed up, and the bottle mouth is covered by the cover 3 due to the tooth direction. When the outer cap 1 is opened on the bottle mouth, the outer cap 1 pulls the inner plug 2 out of the bottle mouth through the card 12. Meanwhile, the movement direction of the ratchet and the barrier strip at the moment is the reverse tooth direction, so that the easily broken connecting piece is broken due to the stress of the ratchet and cannot be restored, and whether the bottle is opened or not can be known by observing whether the anti-counterfeiting structure is damaged or not, thereby playing an anti-counterfeiting effect. The anti-counterfeiting structure innovatively utilizes the effect that the ratchet can only transfer force unidirectionally, the anti-counterfeiting effect can be achieved only by screwing the integrated cover for the first time, the anti-counterfeiting mechanism does not need to be machined again subsequently, the production efficiency is improved, the labor cost is reduced, and the anti-counterfeiting and anti-theft effects are good.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
