Description

Technical Field

[0001] The invention relates to the technical field of packaging, and in particular to a child-proof packaging for batteries. Background Art

[0002] At present, many electrical appliances, including hearing aids, are powered by button batteries. Therefore, consumers generally prepare a large number of button batteries at home for backup. Generally, button batteries are stored in a specific packaging structure. Initially, the packaging structure of button batteries adopts a structure that is easy for consumers to open and use, but these packaging structures are also easy for children to open and are not child-proof. There is a risk that children may accidentally swallow button batteries and cause physical damage. Therefore, the child-proof requirements of battery packaging structures become particularly important.

[0003] Although some existing battery packaging structures can meet the child-proof requirements, they also have many shortcomings. For example, some manufacturers use a medicine bottle-type packaging structure. When taking the battery, you need to rotate the bottle cap to open it. Although it has a child-proof effect, the batteries are stacked in the bottle, and there is a risk of short circuit. For another example, Chinese patent application CN202080025639.9 and U.S. Patent US20230007966A1 both use blister covers to encapsulate batteries, which can avoid battery stacking. When taking the battery, use scissors to cut the blister cover and take out the battery. Although these packaging structures have a child-proof effect, they also have the problem of inconvenience in access for consumers. In Chinese patent application CN202080025639.9 and U.S. patent US20230007966A1, in order to prevent the battery from being cut during cutting, the space reserved for cutting inside the blister cover is smaller in width than the battery. Therefore, after cutting the reserved space, the battery cannot be taken out directly. Multiple cutting and other actions are required to take out the battery, which brings great inconvenience to consumers.

[0004] Even if the width of the reserved space is increased, such as Figure 1 and Figure 2 As shown, since the battery is packaged with a blister cover, when the blister cover is cut, the blister cover will collapse inward due to the shearing force and pressure of the scissors, and the blunter the scissors, the more serious the collapse will be, resulting in the inability to directly remove the battery after cutting the blister cover, and more actions are required, such as multiple cutting or leveling the incision, before the battery can be removed. Multiple cutting and leveling the incision will bring inconvenience in operation, and multiple cutting will also drop many packaging fragments, which is not conducive to cleaning. There is also a risk of cutting the battery, and since the cutting opening is small, the collapse at the opening is not easy to level, which increases the difficulty of removing the battery.

[0005] If the height of the blister cover is increased blindly, the battery packaging volume will be too large. When the blister cover is formed, the blister cover will be easily thinned due to the excessive height of the outward protrusion, which will further increase the degree of collapse during shearing, which is also not conducive to shearing and taking out the battery, and may even cause the risk of damage to the blister cover. When the height of the blister cover increases, the space inside it becomes larger, resulting in the battery being unable to be reliably limited and moving around. The battery is also easily damaged or brings other risks due to collision, and the packaging independence of multiple batteries cannot be guaranteed. In addition, the increase in the height of the blister cover will also cause the scissors to open at a larger angle when cutting, which is not conducive to force shearing. Summary of the invention

[0006] In order to overcome the deficiencies of the prior art, an object of the present invention is to provide a child-proof battery package that can meet the child-proof requirements while also being convenient for consumers to open the package to take out the battery.

[0007] To solve the above problems, the technical solution adopted by the present invention is as follows: a child-proof battery packaging, comprising a closed blister shell, wherein at least one battery limiting groove is arranged inside the blister shell, and the battery limiting groove comprises a battery accommodating groove and a battery extraction groove which are interconnected; first limiting protrusions are distributed on both sides of the battery accommodating groove, and at least one of the first limiting protrusions has a first supporting protrusion, and the first supporting protrusion is located on a side of the first limiting protrusion close to the battery extraction groove, and there is a gap between the top surface of the first supporting protrusion and the top surface of the battery extraction groove to reserve shear clearance space in the first direction, wherein the first direction is the height direction of the battery; the battery extraction groove protrudes outward from the first in the second direction and the third direction. A support protrusion is provided on the top surface of the battery removal groove to reserve a shearing clearance space in the second direction and the third direction, and the width and height of the battery removal groove are respectively greater than the width and height of the battery, wherein the second direction is the width direction of the battery removal groove, and the third direction is the removal direction of the battery; the top surface of the battery removal groove has a second support protrusion extending toward the bottom surface, the second support protrusion is located on the side of the battery removal groove close to the battery accommodating groove, and the bottom surface of the second support protrusion is attached to the top surface of the first support protrusion; a shearing protrusion is provided on the outside of the blister shell corresponding to the position of the battery removal groove, the shearing protrusion protrudes outward from the first support protrusion in both the second direction and the third direction, and when not sheared, the shearing protrusion closes the battery removal groove.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] 1. This child-proof battery packaging has a closed blister shell, and when not cut, the shearing protrusion can close the battery removal slot, so that children cannot easily remove the battery inside the blister shell, thus meeting the child-proof requirements;

[0010] 2. A battery limiting groove is provided inside the blister shell, and first limiting protrusions are distributed on both sides of the battery limiting groove, which can limit the battery to prevent the battery from moving around. When there are multiple battery limiting grooves, the batteries in the multiple battery limiting grooves are packaged independently of each other. When one battery is taken out, the remaining batteries are not affected, and the child-proof requirements are still met;

[0011] 3. When the battery needs to be removed, first place the shearing protrusion upwards so that the battery enters the battery receiving slot under the action of gravity, and then cut the shearing protrusion along the second direction. Since the position of the shearing protrusion corresponds to the position of the battery removal slot, and the battery removal slot has shearing clearance space in the second and third directions, the scissors will not cut the battery, which can protect the battery and avoid damage to the battery. The shearing protrusion also has a certain deformation space, so that consumers can easily apply force to cut the shearing protrusion. When cutting, the battery remains in the battery receiving slot and is not squeezed by the blister shell;

[0012] 4. When the shearing protrusion is cut open with force, the shearing protrusion is subjected to pressure, and the first supporting protrusion and the second supporting protrusion form a support at the edge of the battery extraction slot close to the battery receiving slot, so that the deformation of the shearing protrusion is limited and the battery extraction slot is not blocked due to excessive collapse. Therefore, after the shearing protrusion is cut open, the opening of the battery extraction slot is facing downward, and the battery will fall out easily from the opening of the battery extraction slot under the action of gravity;

[0013] 5. Since the scissors used in daily life will become blunt after long-term use, and blunt scissors mean that greater force is required for cutting, the pressure on the shearing protrusion will increase, and there is a risk of excessive collapse of the shearing protrusion. Therefore, in the packaging structure, first, the shearing protrusion protrudes outward from the first supporting protrusion in both the second direction and the third direction, so even if the shearing protrusion collapses, it mainly occurs at the part protruding outward from the first limiting protrusion; second, through the cooperative support of the first supporting protrusion and the second supporting protrusion, the degree of collapse of the shearing protrusion can be greatly limited; third, the battery removal slot also retains a shearing clearance space in the first direction, so even if the shearing protrusion collapses inward under a large pressure, it only collapses above the first supporting protrusion, and due to the cooperative support of the first supporting protrusion and the second supporting protrusion, the collapse above the first supporting protrusion is limited, and it is difficult to collapse inward over the first supporting protrusion, that is, the collapsed material will only remain in the shearing clearance space in the first direction; therefore, through the structural design of these three places, it is possible to prevent the blister shell from collapsing excessively without increasing the height of the blister shell too much, and even if the consumer applies a large force to shear, the width and height of the battery removal slot opening can still be kept larger than the width and height of the battery, without affecting the removal of the battery;

[0014] From the above five points of analysis, it can be seen that this packaging structure adopts a simple and sophisticated structural design. It does not need to increase the height of the blister shell too much. It can meet the child-proof requirements while making it easy for consumers to remove the battery. When removing the battery, there is no need to cut it multiple times, and there is no need to use hands or other tools to flatten the cut after cutting. It only needs to cut the shear protrusion once along the second direction, and then use gravity to easily take out the battery. The operation is more convenient and quick, more user-friendly, and more suitable for middle-aged and elderly users who use hearing aids.

[0015] In the above-mentioned child-proof battery packaging, the blister shell includes an outer cover and an inner cover connected to each other; the shear protrusion is arranged on the outside of the outer cover, and the second supporting protrusion is arranged on the inside of the outer cover; the first limiting protrusion is arranged on the inside of the inner cover; the battery accommodating groove includes a first accommodating groove arranged on the inside of the outer cover and a second accommodating groove arranged on the inside of the inner cover; the battery removal groove includes a first removal groove arranged on the inside of the outer cover and a second removal groove arranged on the inside of the inner cover.

[0016] In the above-mentioned child-proof battery package, a recessed portion is provided on the outside of the outer cover at a position corresponding to the first limiting protrusion, so as to form a second limiting protrusion inside the outer cover, and the second limiting protrusion is used to limit the position of the battery tape; the bottom surface of the second limiting protrusion is attached to the top surface of the first limiting protrusion, and the second supporting protrusion is provided at the edge of the second limiting protrusion.

[0017] In the above-mentioned child-proof battery package, the side wall of the first supporting protrusion and the side wall of the second supporting protrusion are both in the shape of an arc surface.

[0018] In the above-mentioned child-proof battery packaging, the outer cover and the inner cover are welded or riveted to form the blister shell.

[0019] The above-mentioned child-proof battery packaging also includes a hanging card, and the blister shell is installed on the hanging card.

[0020] In the above-mentioned child-proof battery packaging, the blister shell is in the shape of a turntable and can rotate relative to the hanging card, and there are multiple battery limiting grooves distributed in the circumference of the blister shell; when the shear protrusion rotates to the first edge of the hanging card, the shear protrusion protrudes outward from the first edge of the hanging card, and the first supporting protrusion does not protrude from the first edge of the hanging card.

[0021] In the above-mentioned child-proof battery package, the outer side of the shearing protrusion is planar.

[0022] In the above-mentioned child-proof battery package, a rivet hole is opened on the hanging tag, a first rivet structure is provided in the middle of the outer cover, and a second rivet structure is provided in the middle of the inner cover. The first rivet structure and the second rivet structure both pass through the rivet hole and are riveted together.

DETAILED DESCRIPTION

[0037] The embodiments of the present invention are described in detail below. Figures 3 to 10 The embodiment of the present invention provides a child-proof battery packaging, including a closed blister shell 100, wherein the battery 300 is packaged inside the closed blister shell 100, and children cannot easily open the closed blister shell 100, thereby meeting the child-proof requirement. A blister shell 100 may package only one battery 300, or may package multiple batteries 300. When multiple batteries 300 are packaged in a blister shell 100, the multiple batteries 300 are packaged independently of each other.

[0038] At least one battery limiting groove 110 is provided inside the blister shell 100, and the battery limiting groove 110 is used to place the battery 300 and limit the battery 300 to prevent the battery 300 from moving around. When multiple batteries 300 are packaged in one blister shell 100, multiple battery limiting grooves 110 are provided, and the multiple battery limiting grooves 110 are separated from each other to prevent the batteries 300 from contacting each other.

[0039] Reference Figure 4 , Figure 5 as well as Figures 8 to 10 The battery limiting groove 110 includes a battery receiving groove 111 and a battery removal groove 112 which are interconnected. When the battery 300 is not removed, the battery removal groove 112 is closed and the battery 300 is placed in the battery receiving groove 111. Of course, the battery 300 can also move slightly between the battery receiving groove 111 and the battery removal groove 112. When the shearing protrusion 121 needs to be cut open, the battery 300 is located in the battery receiving groove 111. When the battery 300 is removed, the battery 300 can enter the battery removal groove 112 from the battery receiving groove 111 and fall out from the opening of the battery removal groove 112. Figure 4 , Figure 5 and Figure 7, first limiting protrusions 131 are distributed on both sides of the battery accommodating groove 111. When there are multiple battery limiting grooves 110, there are also multiple first limiting protrusions 131, and the battery accommodating grooves 111 and the first limiting protrusions 131 are distributed at intervals. The first limiting protrusions 131 on both sides of the battery accommodating groove 111 can limit the battery 300 so that the battery 300 can be kept in the battery limiting groove 110. At least one of the first limiting protrusions 131 has a first supporting protrusion 132. In this embodiment, the first limiting protrusions 131 on both sides of the battery accommodating groove 111 are provided with first supporting protrusions 132, and there is a gap between the top surface of the first supporting protrusion 132 and the top surface of the battery removal groove 112 to reserve shear clearance space in the first direction, wherein the first direction is the height direction of the battery 300, wherein, in Figure 4 In order to better show the battery limiting groove 110, one of the batteries 300 has been hidden.

[0040] Reference Figure 4 , Figure 5 and Fig. 9 The battery extraction slot 112 protrudes outward from the first supporting protrusion 132 in both the second direction and the third direction to reserve shear clearance space in the second direction and the third direction, and the width and height of the battery extraction slot 112 are respectively greater than the width and height of the battery 300, wherein the second direction is the width direction of the battery extraction slot 112, and the third direction is the extraction direction of the battery 300. Figure 8 , the top surface of the battery extraction slot 112 has a second support protrusion 122 extending toward the bottom surface, the second support protrusion 122 is located on the side of the battery extraction slot 112 close to the battery receiving slot 111, and the bottom surface of the second support protrusion 122 is in contact with the top surface of the first support protrusion 132; the outside of the blister shell 100 is provided with a shearing protrusion 121 corresponding to the position of the battery extraction slot 112, the shearing protrusion 121 protrudes outward from the first support protrusion 132 in both the second direction and the third direction, and when not sheared, the shearing protrusion 121 closes the battery extraction slot 112. When the first limiting protrusions 131 on both sides of the battery receiving slot 111 are provided with the first support protrusion 122, the corresponding positions on both sides of the top surface of the battery extraction slot 112 are also provided with the second support protrusion 122, so that both sides of the shearing protrusion 121 along the second direction can be supported by the first support protrusion 132 and the second support protrusion 122, which can be used by both left-handed and right-handed consumers.

[0041] Compared with the prior art, the child-proof battery packaging has a closed blister shell 100, and when not sheared, the shearing protrusion 121 can close the battery removal slot 112, so that children cannot easily remove the battery 300 inside the blister shell 100, thereby meeting the child-proof requirements. A battery limiting slot 110 is provided inside the blister shell 100, and first limiting protrusions 131 are distributed on both sides of the battery limiting slot 110, which can limit the battery 300 to prevent the battery 300 from moving around. When multiple battery limiting slots 110 are provided, the batteries 300 in the multiple battery limiting slots 110 are packaged independently of each other. When one battery 300 is taken out, the remaining batteries 300 are not affected, and the child-proof requirements are still met.

[0042] When the battery 300 needs to be removed, the shearing protrusion 121 is first placed upwards so that the battery 300 enters the battery receiving slot 111 under the action of gravity, and then the shearing protrusion 121 is sheared along the second direction. Since the position of the shearing protrusion 121 corresponds to the position of the battery removal slot 112, and the battery removal slot 112 has shearing clearance space in both the second and third directions, the scissors will not shear the battery 300, which can protect the battery 300 and prevent the battery 300 from being damaged. The shearing protrusion 121 also has a certain deformation space, so that consumers can easily apply force to cut the shearing protrusion 121. When cutting, the battery 300 remains in the battery receiving slot 111, and is not squeezed by the blister shell 100. When applying force to cut the shearing protrusion 121, the shearing protrusion 121 is subjected to pressure, referring to Figures 3 to 5 The first supporting protrusion 132 and the second supporting protrusion 122 form a support at the edge of the battery removal groove 112 close to the battery receiving groove 111, so that the deformation of the shearing protrusion 121 is limited and the battery removal groove 112 is not blocked due to excessive collapse. Therefore, after cutting the shearing protrusion 121, the opening of the battery removal groove 112 is facing downward, and the battery 300 will easily fall out from the opening of the battery removal groove 112 under the action of gravity.

[0043] Since the scissors used in daily life will become blunt after long-term use, and blunt scissors mean that greater force is required for cutting, the pressure on the shearing protrusion 121 will increase, and there is a risk of excessive collapse of the shearing protrusion 121. Therefore, in the packaging structure, first, the shearing protrusion 121 protrudes outward from the first supporting protrusion 132 in both the second direction and the third direction. Figure 4 , even if the shearing protrusion 121 collapses, it mainly occurs at the part protruding outward from the first limiting protrusion 131; secondly, the cooperation and support of the first supporting protrusion 132 and the second supporting protrusion 122 can greatly limit the collapse of the shearing protrusion 121; thirdly, the battery removal slot 112 also retains the shearing clearance space in the first direction, therefore, referring to Figure 5, even if the shear protrusion 121 collapses inwardly under a large pressure, the collapse only occurs above the first supporting protrusion 132. Due to the cooperative support of the first supporting protrusion 132 and the second supporting protrusion 122, the collapse above the first supporting protrusion 132 is limited, and it is difficult to collapse inwardly over the first supporting protrusion 132, that is, the collapsed material will only remain in the shear clearance space in the first direction; therefore, through the structural design of these three places, the excessive collapse of the blister shell 100 can be prevented without increasing the height of the blister shell 100 too much, referring to Figure 6 Even if the consumer applies a large force to cut, the width and height of the opening of the battery extraction slot 112 can still be kept larger than the width and height of the battery 300, and the removal of the battery 300 is not affected.

[0044] Therefore, the packaging structure adopts a simple and sophisticated structural design. Without increasing the height of the blister shell 100 too much, it can meet the child-proof requirements while making it easy for consumers to take out the battery 300. When taking out the battery 300, there is no need to cut it multiple times, and there is no need to use hands or other tools to flatten the cut after cutting. It only needs to cut the shear protrusion 121 once along the second direction, and then use gravity to easily take out the battery 300. The operation is more convenient and quick, more user-friendly, and more suitable for middle-aged and elderly users who use hearing aids.

[0045] Furthermore, the blister shell 100 is made of a blister film or sheet through a blister process. The material of the film or sheet includes but is not limited to PVC, PC, PET, PU and the like. The thickness of the film or sheet is between 0.1 mm and 1 mm, preferably between 0.2 mm and 0.5 mm. Figures 6 to 10 The blister shell 100 includes an outer cover 120 and an inner cover 130 connected to each other. The outer cover 120 and the inner cover 130 can be welded and fixed together by ultrasonic welding or riveting. The outer cover 120 and the inner cover 130 are welded to form the blister shell 100 encapsulating the battery 300. Without tools, the blister outer cover 120 is not easy to open, thereby achieving a child-proof effect. Further, the first limiting protrusion 131 is provided inside the inner cover 130, referring to Figures 7 to 9, the shearing protrusion 121 is arranged outside the outer cover 120, the second supporting protrusion 122 is arranged inside the outer cover 120, and a recessed portion 125 is arranged outside the outer cover 120 at a position corresponding to the first limiting protrusion 131, so as to form a second limiting protrusion 126 inside the outer cover 120, and the second limiting protrusion 126 is used to limit the position of the battery tape 310. Therefore, the battery 300 and the battery tape 310 can be prevented from moving around by the cooperation and limitation of the first limiting protrusion 131 and the second limiting protrusion 126. Preferably, the recessed height of the recessed portion 125 is 1.5 mm, and the protruding distance of the shearing protrusion 121 from the first supporting protrusion 132 in the second direction and the third direction is 2 mm.

[0046] Specifically, the bottom surface of the second limiting protrusion 126 is attached to 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 and the top surface of the first limiting protrusion 131 can be attached to each other and welded to ensure the relative position between the two and ensure the mutual support between the two. Specifically, the battery accommodating groove 111 includes a first accommodating groove 123 arranged inside the outer cover 120 and a second accommodating groove 133 arranged inside the inner cover 130; the battery extraction groove 112 includes a first extraction groove 124 arranged inside the outer cover 120 and a second extraction groove 134 arranged inside the inner cover 130. Furthermore, the side walls of the first supporting protrusion 132 and the side walls of the second supporting protrusion 122 are both arc-shaped, which can improve the supporting strength between the first supporting protrusion 132 and the second supporting protrusion 122, and because the first supporting protrusion 132 is located at the junction between the battery accommodating groove 111 and the battery removal groove 112, the arc-shaped first supporting protrusion 132 can also guide the battery 300 to slide out.

[0047] Further, refer to Figures 3 to 8 The child-proof battery packaging in this embodiment also includes a hanging tag 200, and the blister shell 100 is installed on the hanging tag 200. The hanging tag 200 can be printed with information such as instructions. Specifically, a hanging hole 220 is provided on the hanging tag 200 to facilitate hanging, selling and storing. Furthermore, the blister shell 100 is in the shape of a turntable and can rotate relative to the hanging tag 200. The turntable-shaped blister shell 100 has a more beautiful appearance, and the rotatable turntable structure can also increase the interest of the packaging structure. Specifically, a rivet hole 210 is provided on the hanging tag 200, a first rivet structure 127 is provided in the middle of the outer cover 120, and a second rivet structure 135 is provided in the middle of the inner cover 130. The first rivet structure 127 and the second rivet structure 135 both pass through the rivet hole 210 and are riveted together to achieve the rotatability of the blister shell 100.

[0048] Furthermore, there are a plurality of battery limiting grooves 110 distributed in the circumferential direction of the blister shell 100, referring to Figure 3 and Figure 4 When taking out the battery 300, the blister shell 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 from the first edge of the hanging card 200, and the first supporting protrusion 132 does not protrude from the first edge of the hanging card 200. At this time, the first edge of the hanging card 200 can be used as a shearing reference line, and shearing is performed along the first edge of the hanging card 200. Not only will the first supporting protrusion 132 not be sheared, the shearing action will not be affected, and the shearing action will not be damaged by shearing, and the hanging card 200 will not be sheared. Each time a battery 300 is taken out, a shearing protrusion 121 can be rotated to the first edge of the hanging card 200 for shearing. After multiple shearings, the hanging card 200 can still remain intact. After taking out multiple batteries 300, the hanging card 200 still has the original size, so it is not easy to be lost, and it can be convenient for consumers to find and take. After cutting one shearing protrusion 121, the other shearing protrusions 121 are not affected, and the battery 300 can still be stored in the battery limiting groove 110 corresponding to the other shearing protrusions 121, and still has the child-proof function. In order to further improve the convenience during cutting, the outer side of the shearing protrusion 121 is flat. When taking the battery 300, the blister shell 100 is rotated. 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 can facilitate operation. There is no need to preset a shearing reference line on the hanging card 200 during processing, which can simplify the processing process of the battery 300 packaging structure.

[0049] It should be noted that in the description of the present invention, if there are any orientation descriptions, such as up, down, front, back, left, right, etc., the orientations or positional relationships indicated are all based on the orientations or positional relationships shown in the drawings.
