[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0024] The anti-swallowing button battery of the embodiment of the utility model is specifically a button battery, including a battery body 10 and an anti-swallowing film coating belt 20 coated on the surface of the battery body 10; wherein, the internal structure of the battery body 10 can refer to the button battery in the prior art and will not be expanded here; the battery body 10 has a positive electrode surface 11, a negative electrode surface 12, a radial side wall surface 13, and a sealing R-angle transition surface 14; wherein, the anti-swallowing film coating belt 20 is arranged on at least one of the positive electrode surface 11, the negative electrode surface 12, the radial side wall surface 13, and the sealing R-angle transition surface 14.

[0025] Furthermore, the thickness of the anti-swallowing film coating tape 20 is less than 0.5 mm; preferably, the thickness of the anti-swallowing film coating tape 20 is 0.01 mm to 0.1 mm, specifically 0.02 mm; in an optional embodiment, the anti-swallowing film coating tape 20 preferably protrudes from the surface of the battery body 10, so that it can contact the oral saliva more quickly when swallowed by mistake, reducing the time of releasing the irritating taste, so that children can spit out the battery quickly. It should be noted here that compared with the thickness of the battery itself, the anti-swallowing film coating tape 20 of the embodiment is extremely thin. On the one hand, it will not affect the use of the battery. On the other hand, it can also carry a certain amount of edible emetic to release a sufficient amount of irritating taste when swallowed by mistake.

[0026] The pattern shape of the anti-swallowing film coating tape 20 in the embodiment is at least one of a straight line, a cross, a semi-arc and a circular ring, and can also be other regular or irregular shapes, such as warning patterns, etc. Any shape that does not affect the conductive contact of the battery is acceptable, and can be coated at any satisfactory position to prevent children from swallowing by mistake by stimulating their taste buds. Examples will not be given one by one here.

[0027] The following is an introduction using the anti-swallowing film coating belt 20 being arranged at different positions as an example.

[0028] In such Figure 1 In the embodiment 1 shown, the anti-swallowing film coating belt 20 is arranged on the positive electrode surface 11, wherein a positive electrode mark is arranged on the positive electrode surface 11, and the anti-swallowing film coating belt 20 is arranged in an annular belt shape and is arranged around the positive electrode mark.

[0029] In such Figure 2In the illustrated embodiment 2, the anti-swallowing film coating belt 20 is disposed on the negative electrode surface 12, wherein a negative electrode mark is disposed on the negative electrode surface, and the anti-swallowing film coating belt 20 is disposed in an annular belt shape and is disposed around the negative electrode mark.

[0030] In such Figure 3 In the illustrated embodiment 3, the anti-swallowing film coating band 20 is disposed on the radial side wall surface 13 , wherein the anti-swallowing film coating band 20 is configured in a ring shape and is disposed around the outer circumference of the radial side wall surface 13 .

[0031] In a preferred embodiment, the anti-swallowing film coating tape 20 can also be arranged at the sealing R angle transition surface 14. The anti-swallowing film coating tape 20 will not affect the outer dimensions of the battery and can be directly applied to the existing production process. Specifically, the sealing R angle transition surface 14 has a first transition surface 141, an R angle transition surface 142 and a second transition surface 143 connected to each other, wherein the first transition surface 141 is connected to the positive electrode surface 11, and the second transition surface 143 is connected to the negative electrode surface 12. Figure 4 In the embodiment 4 shown, the anti-swallowing film coating belt 20 is arranged on the R angle transition surface 142, and the anti-swallowing film coating belt 20 is arranged in a ring shape, which covers the surface of the R angle transition surface 14. Figure 5 In the embodiment 5 shown, the anti-swallowing film coating belt 20 is arranged on the first transition surface 141, and the anti-swallowing film coating belt 20 is arranged in a ring shape, which covers the surface of the first transition surface 141. Figure 6 In the illustrated embodiment 6, the anti-swallowing film coating belt 20 is disposed on the second transition surface 143 . The anti-swallowing film coating belt 20 is configured in a ring shape and covers the surface of the second transition surface 143 .

[0032] As an extension of the embodiment of the utility model, the surface of the anti-swallowing film coating tape 20 is also coated with a protective layer formed of edible gelatin, which wraps the anti-swallowing film coating tape 20 to prevent the pungent taste of the edible emetic from leaking out, so that it remains effective during long-term storage. Preferably, the thickness of the protective layer is set to no more than 0.1 mm, so as not to affect the rapid melting of the anti-swallowing film coating tape 20 and the rapid release of the pungent taste under the moistening of oral saliva.

[0033] For example, when preparing the above-mentioned battery, the battery coated with the anti-swallowing film coating tape 20 is first placed in an oven at 35°C to 45°C for 8 to 12 minutes to achieve the shaping of the anti-swallowing film coating tape 20. Specifically, the temperature of the oven is, for example, 40°C, and the duration is, for example, 10 minutes to achieve the shaping of the anti-swallowing film coating tape 20; then, the edible gelatin forming the protective layer is coated again on the surface of the anti-swallowing film coating tape 20, so as to obtain a battery having a protective layer and the anti-swallowing film coating tape 20. In other embodiments, it can also be obtained by, for example, natural drying, which is not expanded or limited here.

[0034] The anti-swallowing film coating tape 20 in the embodiment includes the following components and their weight portions: 1-3 parts of edible gelatin, 0.2-1.0 parts of edible emetic, 0.1-0.5 parts of setting agent, and 6-9 parts of water; the edible emetic can release a pungent taste when swallowed into the mouth by mistake. Exemplarily, the specific components and weight portions of an anti-swallowing film coating tape 20 are: 1.8 parts of edible gelatin, 0.5 parts of edible emetic, 0.2 parts of setting agent, and 7.5 parts of water; the edible emetic can release a pungent taste when swallowed into the mouth by mistake. Among them, the edible emetic includes at least one of a spicy agent, a sour agent, a bitter agent, and mint; among them, the spicy agent includes, for example, spicy powder or mustard, the sour agent includes, for example, edible vinegar essence, and the flavoring agent includes, for example, edible berberine; the setting agent includes, for example, edible agar or sodium carboxymethyl starch.

[0035] The anti-swallowing film coating tape 20 in the embodiment almost completely covers the irritating taste (spicy, sour, bitter, minty, etc.) during normal storage and battery use, and does not emit a strong irritating taste, such as a chili pepper that does not look spicy, smells slightly spicy, and tastes very spicy. Once a child swallows the battery by mistake, the anti-swallowing film coating tape 20 on the battery surface will quickly melt under the moistening of the saliva in the mouth, and the anti-swallowing film coating tape 20 will release a pungent taste, making the child feel uncomfortable and immediately spit out the battery.

[0036] Although the present invention is described above through embodiments, it should be understood that the above embodiments are only used to exemplarily describe the feasible implementation methods of the present invention, and should not be interpreted as limiting the scope of protection of the present invention. That is, any replacement or change made by those skilled in the art in accordance with the present invention should also be covered by the scope of protection of the claims of the present invention.
