DETAILED DESCRIPTION OF THE EMBODIMENTS

[0038] The following provides a detailed description of the embodiments of the present disclosure, with reference to FIGS. 3 to 10. The embodiments of the present disclosure provide a child-resistant packaging for button cell batteries, comprising a set of blister shells 100. The battery 300 is encapsulated in the inner portion of the set of blister shells 100 and cannot be easily opened by children, thus meeting child-resistant requirements. One set of blister shells 100 can encapsulate only one battery 300 or a plurality of batteries 300. When a plurality of batteries 300 are encapsulated in one set of blister shells 100, they are packaged independently of each other.

[0039] The inner portion of the set of blister shells 100 is provided with at least one battery limiting cavity 110, the battery limiting cavity 110 is configured to place the battery 300 and limit the battery 300 to prevent it from moving around. When the plurality of batteries 300 are packaged in one set of blister shells 100, there are a plurality of battery limiting cavities 110, and the plurality of battery limiting cavities 110 are separated from each other to prevent the batteries 300 from contacting each other.

[0040] As shown in FIGS. 4, 5, and 8 to 10, the battery limiting cavity 110 comprises a battery accommodating cavity 111 and a battery removal cavity 112 that are interconnected. When the battery 300 is not removed, the battery removal cavity 112 is closed and the battery 300 is placed inside the battery accommodating cavity 111. Of course, the battery 300 can also move slightly between the battery accommodating cavity 111 and the battery removal cavity 112. When it is necessary to cut open the shearing protrusion 121, the battery 300 is stored in the battery accommodating cavity 111. When removing the battery 300, it enters the battery removal cavity 112 from the battery accommodating cavity 111 and falls out from the opening of the battery removal cavity 112. As shown in FIGS. 4, 5, and 7, the first limiting protrusions 131 are distributed on both sides of the battery accommodating cavity 111. When there are a plurality of battery limiting cavities 110, there are also a plurality of first limiting protrusions 131, and battery accommodating cavities 111 are distributed alternatively with first limiting protrusions 131. The first limiting protrusions 131 on both sides of the battery accommodating cavity 111 can limit the battery 300, so that the battery 300 can be kept in the battery limiting cavity 110. At least one first limiting protrusion 131 comprises a first supporting protrusion 132. In this embodiment, the first supporting protrusions 132 are provided on the first limiting protrusions 131 on both sides of the battery accommodating cavity 111, and there is a gap formed between the top surface of the first supporting protrusion 132 and the top surface of the battery removal cavity 112 to reserve shear clearance space in the first direction, wherein the first direction is the height direction of the battery 300. Wherein, in FIG. 4, in order to better show the battery limiting cavity 110, one of the batteries 300 has been hidden.

[0041] As shown in FIGS. 4, 5, and 9, the battery removal cavity 112 protrudes outward beyond the first supporting protrusion 132 in both the second and third directions to retain the shear clearance space in both the second and third directions. The width and the height of the battery removal cavity 112 are respectively greater than those of the battery 300, amongst the second direction is the width direction of the battery removal cavity 112 and the third direction is the removal direction of the battery 300. As shown in FIG. 8, the top surface of the battery removal cavity 112 comprises a second supporting protrusion 122 protruding towards the bottom surface. The second supporting protrusion 122 is located on one side of the battery removal cavity 112 close to the battery accommodating cavity 111, and the bottom surface of the second supporting protrusion 122 is in contact with the top surface of the first supporting protrusion 132. A shearing protrusion 121 is provided on the outside of the set of blister shells 100 at a position corresponding to the battery removal cavity 112; the shearing protrusion 121 protrudes outward beyond the first supporting protrusion 132 in both the second direction and the third direction; when not sheared, the shearing protrusion 121 closes the battery removal cavity 112. When each first limiting protrusion 131 located at both sides of the battery accommodating cavity 111 is provided with a first supporting protrusions 132, the corresponding positions on both sides of the top surface of the battery removal cavity 112 are also provided with the second supporting protrusions 122, so that both sides of the shearing protrusions 121 along the second direction can be supported by the first supporting protrusions 132 and the second supporting protrusions 122, which is beneficial to both consumers who are left-handed or right-handed.

[0042] Compared with the prior art, this battery child-resistant packaging comprises a set of blister shells 100, when not sheared, the shearing protrusion 121 can close the battery removal cavity 112, so that the child cannot easily take out the battery 300 from the blister shells 100, thus meeting the child-resistant requirements. A plurality of battery limiting cavities 110 are formed inside the set of blister shells 100, the first limiting protrusions 131 are distributed on both sides of each battery limiting cavity 110, which can limit the position of batteries 300 and keep batteries 300 from moving around. When there are a plurality of battery limiting cavities 100, the batteries 300 in the battery limiting cavities 110 are packaged independently, and when one battery 300 is removed, the rest batteries 300 are not affected and the child-resistant requirements are still meet.

[0043] When a battery 300 is required to be removed, the shearing protrusion 121 is tilted upwards firstly, so that the battery 300 enters the battery accommodating cavity 111 by gravity, and then cut the shearing protrusion 121 along the second direction. Since each shearing protrusion 121 corresponds to each battery removal cavity 112, and each battery removal cavity 112 is reserved with a shear clearance space in the second direction and the third direction, so that the battery 300 cannot be cut, the battery 300 can be protected, the battery 300 is prevented from being damaged; and the shearing protrusion 121 also has a certain deformation space, so that a consumer can easily apply forces to cut the shearing protrusion 121, and the battery 300 is kept in the battery accommodating cavity 111 during cutting, so that the battery 300 will not be squeezed by the blister shells 100. When applying force to cut open the shearing protrusion 121, the shearing protrusion 121 is subjected to pressure. As shown in FIGS. 3 to 5, the first supporting protrusion 132 and the second supporting protrusion 122 form a support at the edge of the battery removal cavity 112 close to the battery accommodating cavity 111, limiting the deformation of the shearing protrusion 121 and preventing excessive dent from blocking the battery removal cavity 112. Therefore, after cutting open the shearing protrusion 121, make the opening of the battery removal cavity 112 tilted, and the battery 300 will easily fall out of the opening of the battery removal cavity 112 under gravity.

[0044] Since scissors used in daily life become blunt after long-term use, which means greater force is required for cutting, therefore the pressure on the shearing protrusion 121 will increase, and there is a risk of excessive dent of the shearing protrusion 121. Therefore, in present packaging structure, firstly, the first shearing protrusion 121 protrudes outward beyond the first supporting protrusion 132 in both the second and third directions. Therefore, as shown in FIG. 4, even if the shearing protrusion 121 dents, it mainly occurs at the part protruding outward beyond the first limiting protrusion 131. Secondly, through the coordinated support of the first supporting protrusion 132 and the second supporting protrusion 122, the degree of dent of the shearing protrusion 121 can be greatly limited. Thirdly, the battery removal cavity 112 also retains a shear clearance space in the first direction. Therefore, as shown in FIG. 5, even when the shearing protrusion 121 dents inward under greater pressure, it only dents above the first supporting protrusion 132. Due to the coordinated support of the first supporting protrusion 132 and the second supporting protrusion 122, the dent above the first supporting protrusion 132 is limited and difficult to dent inward beyond the first supporting protrusion 132. In other words, the dented material will only remain in the shear clearance space in the first direction. Therefore, through the structural design of these three parts, it is possible to prevent the excessive dent of the blister shells 100 without increasing the height of the blister shells 100 too much. As shown in FIG. 6, even if a consumer applies a large force to cut, the width and height of the opening of the battery removal cavity 112 can still be maintained greater than the width and height of the battery 300, without affecting the removal of the battery 300.

[0045] Therefore, it can be seen that this packaging structure adopts a simple and delicate structural design, which does not require an excessive increase in the height of the set of blister shells 100. It can meet the child-resistant requirements while also facilitating consumers to remove batteries 300. When removing the battery 300, there is no need to cut it a plurality of times, and after cutting, there is no need to use hands or other tools to level the incision. It only needs to cut the shearing protrusion 121 once along the second direction, and then the battery 300 can be easily removed under gravity. The operation is more convenient and quicker, more user-friendly, and more suitable for middle-aged and senior hearing aids wearers.

[0046] Furthermore, the set of blister shells 100 is made of blister films or sheets through a blister process. The material of the film or sheet comprises but is not limited to PVC, PC, PET, PU, etc. The thickness of the film or sheet is between 0.1 mm to 1 mm, preferably 0.2 mm to 0.5 mm. Furthermore, as shown in FIGS. 6 to 10, the set of blister shells 100 comprises an outer cover 120 and an inner cover 130 that are interconnected. The outer cover 120 and the inner cover 130 can be thermo-welded and together. The outer cover 120 and the inner cover 130 are thermo-welded together to form an encapsulated set of blister shells 100 of the battery 300. Without tools, the outer cover 120 is not easy to open, thus achieving the child-resistant effect. Furthermore, the first limiting protrusion 131 is located in the inner portion of the inner cover 130, as shown in FIGS. 7 to 9. The shearing protrusion 121 is arranged on the outer portion of the outer cover 120, and the second supporting protrusion 122 is arranged at the inner portion of the outer cover 120. A recess 125 is provided on the outer portion of the outer cover 120 at a position corresponding to the first limiting protrusion 131, so as to form a second limiting protrusion 126 in the inner portion of the outer cover 120. The second limiting protrusion 126 is used to limit the position of the battery tab 310. Therefore, the cooperation of the first limiting protrusion 131 and the second limiting protrusion 126 can prevent the battery 300 and the battery tab 310 from moving around. Preferably, the recess height of the recess 125 is 1.5 mm, and the protrusion distances of the shearing protrusion 121 protruding outwards beyond the first supporting protrusion 132 in both the second and third directions are all 2 mm.

[0047] Specifically, the bottom surface of the second limiting protrusion 126 is in contact with the top surface of the first limiting protrusion 131, and the second supporting protrusion 122 is arranged at the edge of the second limiting protrusion 126, so as to realize the mutual support between the first supporting protrusion 132 and the second supporting protrusion 122. When welding the outer cover 120 and the inner cover 130, the bottom surface of the second limiting protrusion 126 can be thermo-welded to the top surface of the first limiting protrusion 131 to ensure their relative position and mutual support. Specifically, the battery accommodating cavity 111 comprises a first accommodating cavity 123 arranged in the inner portion of the outer cover 120 and a second accommodating cavity 133 arranged in the inner portion of the inner cover 130. The battery removal cavity 112 comprises a first removal cavity 124 arranged in the inner portion of the outer cover 120 and a second removal cavity 134 arranged in the inner portion of the inner cover 130. Furthermore, the side walls of the first supporting protrusion 132 and the second supporting protrusion 122 are both arc-shaped, so that the supporting between the first supporting protrusion 132 and the second supporting protrusion 122 can be strengthened. Moreover, since the first supporting protrusion 132 is located at the junction between the battery accommodating cavity 111 and the battery removal cavity 112, the arc-shaped first supporting protrusion 132 can also guide the battery 300 to slide out.

[0048] Furthermore, as shown in FIGS. 3 to 8, the child-resistant battery packaging in this embodiment also comprises a hanging card 200, and the set of blister shells 100 is fastened onto the hanging card 200. And information such as a user manual can be printed on the hanging card 200. Specifically, a hanging slot 220 is formed in the hanging card 200 to facilitate hanging, vending and storage. Furthermore, the blister shells 100 is disc shaped and can rotatably fix relative to the hanging card 200. the blister shells 100 in disc shapes is attractive in appearance, and the rotatable structure can also increase the ornamental value of the packaging structure. Specifically, there is a central hole 210 is provided on the hanging card 200, a first compression fastening structure 127 is provided in the middle of the outer cover 120, a second compression fastening structure 135 is provided in the middle of the inner cover 130, and the first compression fastening structure 127 and the second compression fastening structure 135 penetrate through the central hole 210 and are fastened together to achieve the rotatability of the blister shells 100.

[0049] Furthermore, there are a plurality of battery limiting cavities 110 distributed in the circumferential direction of the blister shells 100. As shown in FIGS. 3 and 4, when taking out the battery 300, the blister shells 100 can be rotated. When the shearing protrusion 121 rotates to the first edge of the hanging card 200, the shearing protrusion 121 protrudes outward beyond the first edge of the hanging card 200, and the first supporting protrusion 132 does not protrude beyond the first edge of the hanging card 200. At same time, the first edge of the hanging card 200 can be used as a cutting reference line to cut along the first edge of the hanging card 200, so that the first supporting protrusion 132 is not cut, the cutting action is not affected, the first supporting protrusion 132 is prevented from being damaged by cutting, and the hanging card 200 will not be cut. Each time a battery 300 is taken, one shearing protrusion 121 can be rotated to the first edge of the hanging card 200 for cutting. After a plurality of cuttings, the hanging card 200 can still remain intact. After removing a plurality of batteries 300, the hanging card 200 still has its original size, making it less likely to be lost and easier for consumers to find and use. After cutting open one shearing protrusion 121, the other shearing protrusions 121 are not affected, and the battery 300 can still be stored in the battery limiting cavity 110 corresponding to the other shearing protrusions 121, and still has child-resistant function. In order to further improve the convenience of cutting, the outer side of the shearing protrusion 121 is planar. When a battery 300 is taken, rotate the blister shells 100; when the outer side of the shearing protrusion 121 is approximately parallel to the first edge of the hanging card 200, the shearing protrusion 121 can be cut along the first edge of the hanging card 200, which is convenient for operation and does not require a preset cutting reference line on the hanging card 200, simplifying the printing process of the packaging structure of the battery 300.
