Description

Child-proof packaging for batteries Technical Field

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

[0002] Currently, many electrical appliances, including hearing aids, are powered by button batteries. Therefore, consumers generally prepare a large number of button batteries at home as backup. Generally, button batteries are stored in a specific packaging structure. Initially, the packaging structure of the 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 the button batteries and cause physical harm. Therefore, the child-proof requirements of the battery packaging structure have become particularly important. For example, the United States passed the Reese Act in 2022, requiring that the packaging of button batteries produced and imported after 2023 must meet child-proof requirements, which reflects the importance of child-proof requirements in the battery packaging structure.

[0003] Although some existing battery packaging structures can meet the requirements of child-proofing, they also have many shortcomings. For example, some manufacturers use a medicine bottle-type packaging structure. When taking the battery, it is necessary to rotate and open the bottle cap. Although it has a child-proof effect, the batteries are stacked in the bottle, and there is a risk of short circuit. For 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, scissors are used 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 remove the battery, which brings great inconvenience to consumers.

[0004] Even if the width of the reserved space is increased, as shown in Figures 1 and 2, the battery is packaged in a blister cover. Therefore, when the blister cover is cut, the blister cover will collapse inward due to the shear force and pressure of the scissors. The blunter the scissors, the more severe the collapse. As a result, the battery cannot be directly removed after cutting the blister cover. More actions are required, such as multiple cutting or smoothing the cuts. Multiple cutting and smoothing the cuts will bring operational inconvenience, and multiple cutting will also cause a lot of packaging debris to fall, which is not conducive to cleaning. There is also a risk of cutting the battery. Since the cutting opening is small, the collapse at the opening is not easy to smooth, which increases the difficulty of removing the battery.

[0005] However, if the height of the blister cover is blindly increased, the battery packaging volume will be too large. When the blister cover is formed, the blister cover will easily become thinner 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 create 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 by collision or brings other risks. At the same time, 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 applying force to shear. 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-resistant battery package that can meet the child-resistant requirements while also being convenient for consumers to open the package and remove the batteries.

[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 provided inside the blister shell, and the battery limiting groove includes a battery accommodating groove and a battery removal groove that 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 the side of the first limiting protrusion close to the battery removal groove, and there is a gap between the top surface of the first supporting protrusion and the top surface of the battery removal groove to reserve shear clearance space in the first direction, wherein the first direction is the height direction of the battery; the battery removal groove protrudes outward from the first in the second and third directions. The battery removal slot is a top surface of the battery removal slot having a second support protrusion extending toward the bottom surface, the second support protrusion being located on a side of the battery removal slot close to the battery accommodating slot, and the bottom surface of the second support protrusion is in contact with the top surface of the first support protrusion; a shear protrusion is provided on the outside of the blister shell at a position corresponding to the battery removal slot, the shear protrusion protruding outwardly from the first support protrusion in both the second and third directions, and when not sheared, the shear protrusion closes the battery removal slot.

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

[0009] 1. This child-resistant battery packaging has a closed blister shell. When not cut, the shear protrusion can close the battery removal slot, making it difficult for children to easily remove the battery inside the blister shell, thus meeting the child-resistant requirements.

[0010] 2. A battery retaining groove is provided inside the blister shell. Both sides of the battery retaining groove are provided with first retaining protrusions to retain the battery and prevent it from moving around. When there are multiple battery retaining grooves, the batteries in the multiple battery retaining 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 shear protrusion upwards so that the battery enters the battery compartment under the action of gravity, and then cut the shear protrusion along the second direction. Since the position of the shear protrusion corresponds to the position of the battery removal slot, and the battery removal slot retains shear clearance space in the second and third directions, the scissors will not cut the battery, which can protect the battery and prevent it from being damaged. The shear protrusion also has a certain deformation space, making it easy for consumers to apply force to cut the shear protrusion. During cutting, the battery remains in the battery compartment and is not squeezed by the blister shell.

[0012] 4. When the shear protrusion is cut open with force, the shear 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 shear protrusion is limited and the battery extraction slot is not blocked due to excessive collapse. Therefore, after cutting the shear protrusion, the opening of the battery extraction slot is facing downward, and the battery will easily fall out of 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 this packaging structure, first, the shear protrusion protrudes outward from the first supporting protrusion in both the second and third directions. Therefore, even if the shear protrusion collapses, it will mainly occur at the portion protruding outward from the first limiting protrusion. Second, the coordinated support of the first and second supporting protrusions can greatly limit the degree of collapse of the shear protrusion. Third, the battery removal slot also retains a shear clearance space in the first direction. Therefore, even if the shear protrusion collapses inward under significant pressure, it only collapses above the first supporting protrusion. Due to the coordinated support of the first and second supporting protrusions, the collapse above the first supporting protrusion is limited and it is difficult for the material to collapse inward beyond the first supporting protrusion. In other words, the collapsed material is only retained within the shear clearance space in the first direction. Therefore, through these three structural designs, the blister shell can be prevented from excessively collapsing without significantly increasing its height. Even if the consumer applies significant force to shear the shell, the width and height of the battery removal slot opening can still remain larger than the width and height of the battery, thus not affecting battery removal.

[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, and it can meet the child-proof requirements while also making it easy for consumers to remove the battery. When removing the battery, there is no need to cut 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 remove 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 that are connected to each other; the shear protrusion is provided on the outside of the outer cover, and the second supporting protrusion is provided on the inside of the outer cover; the first limiting protrusion is provided on the inside of the inner cover; the battery accommodating groove includes a first accommodating groove provided on the inside of the outer cover and a second accommodating groove provided on the inside of the inner cover; the battery removal groove includes a first removal groove provided on the inside of the outer cover and a second removal groove provided on the inside of the inner cover.

[0016] In the above-mentioned child-proof battery packaging, 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. The second limiting protrusion is used to limit the position of the battery tape; the bottom surface of the second limiting protrusion is in contact with 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 further comprises a hanging tag, and the blister shell is mounted on the hanging tag.

[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 circumferentially around 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 packaging, the outer side of the shearing protrusion is flat.

[0022] In the above-mentioned child-proof battery packaging, 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.

[0023] In the above-mentioned child-proof battery packaging, the hanging tag is provided with a hanging hole.

[0024] In the above-mentioned child-proof battery packaging, the blister shell is made of a blister-proof film or sheet, and the thickness of the film or sheet is between 0.1 mm and 1 mm.

DETAILED DESCRIPTION

[0037] The following describes an embodiment of the present invention in detail with reference to Figures 3 to 10 . The embodiment of the present invention provides a child-resistant battery packaging, comprising a closed blister housing 100 . Batteries 300 are enclosed within the closed blister housing 100 , making it difficult for children to open the packaging, thereby meeting child-resistant requirements. A single blister housing 100 can contain only one battery 300 , or multiple batteries 300 . When multiple batteries 300 are enclosed within a single blister housing 100 , the batteries 300 are packaged independently of one another.

[0038] At least one battery limiting groove 110 is provided inside the blister shell 100. 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 encapsulated in a 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] Referring to Figures 4, 5, and 8 to 10, the battery retaining groove 110 includes a battery accommodating 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 accommodating groove 111. Of course, the battery 300 can also move slightly between the battery accommodating groove 111 and the battery removal groove 112. When the shearing protrusion 121 is required to cut, the battery 300 is located in the battery accommodating groove 111. When the battery 300 is removed, the battery 300 can enter the battery removal groove 112 from the battery accommodating groove 111 and fall out through the opening of the battery removal groove 112. Referring to Figures 4, 5, and 7, first retaining protrusions 131 are distributed on both sides of the battery accommodating groove 111. If multiple battery retaining grooves 110 are provided, multiple first retaining protrusions 131 are also provided, and the battery accommodating groove 111 and the first retaining protrusions 131 are spaced apart. 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 retained 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 a first supporting protrusion 132, and a gap is formed between the top surface of the first supporting protrusion 132 and the top surface of the battery removal groove 112 to reserve a shear clearance space in the first direction, wherein the first direction is the height direction of the battery 300. In FIG4, one of the batteries 300 is hidden to better illustrate the battery limiting groove 110.

[0040] Referring to Figures 4, 5, and 9, the battery extraction slot 112 protrudes outward from the first support protrusion 132 in both the second and third directions, thereby preserving space for shearing in these directions. The width and height of the battery extraction slot 112 are respectively greater than the width and height of the battery 300. The second direction is the width of the battery extraction slot 112, and the third direction is the direction in which the battery 300 is removed. Referring to 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 proximal to the battery receiving slot 111, and the bottom surface of the second support protrusion 122 abuts against the top surface of the first support protrusion 132. A shearing protrusion 121 is provided on the exterior of the blister housing 100 at a position corresponding to the battery extraction slot 112. The shearing protrusion 121 protrudes outward from the first support protrusion 132 in both the second and third directions. When not sheared, the shearing protrusion 121 seals the battery extraction slot 112. When first supporting protrusions 132 are provided on the first limiting protrusions 131 on both sides of the battery accommodating groove 111, second supporting protrusions 122 are also provided at corresponding positions on both sides of the top surface of the battery removal groove 112, so that both sides of the shearing protrusion 121 along the second direction can be supported by the first supporting protrusions 132 and the second supporting protrusions 122, which can facilitate use by both left-handed and right-handed consumers.

[0041] Compared to the prior art, this child-resistant battery packaging features a closed blister shell 100. When not sheared, the shear protrusions 121 seal the battery removal slot 112, preventing children from easily removing the batteries 300 from the blister shell 100, thus meeting child-resistant requirements. A battery retaining slot 110 is provided within the blister shell 100, with first retaining protrusions 131 located on both sides of the battery retaining slot 110 to retain the batteries 300 and prevent them from moving around. When multiple battery retaining slots 110 are provided, the batteries 300 within the multiple retaining slots 110 are packaged independently of one another. When one battery 300 is removed, the remaining batteries 300 remain unaffected, thus still meeting child-resistant requirements.

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

[0043] Since scissors used daily 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 this packaging structure, first, the shearing protrusion 121 protrudes outward from the first supporting protrusion 132 in both the second and third directions. Therefore, referring to Figure 4, even if the shearing protrusion 121 collapses, it will mainly occur at the part that protrudes outward from the first limiting protrusion 131; second, the coordinated support of the first supporting protrusion 132 and the second supporting protrusion 122 can greatly limit the degree of collapse of the shearing protrusion 121; third, the battery removal slot 112 also retains shear clearance space in the first direction. Therefore, referring to Figure 5, even if the shearing protrusion 121 collapses inward due to greater pressure, it will only collapse above the first supporting protrusion 132. Collapse occurs, and 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 inward beyond the first supporting protrusion 132, 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, the blister shell 100 does not need to be increased too much in height, and it is possible to prevent the blister shell 100 from excessively collapsing. Referring to Figure 6, even if the consumer applies a greater force to shear, the width and height of the opening of the battery removal slot 112 can still be maintained greater than the width and height of the battery 300, without affecting the removal of the battery 300.

[0044] Therefore, this packaging structure adopts a simple and sophisticated structural design. It does not need to increase the height of the blister shell 100 too much. It can meet the child-proof requirements while also making it easy for consumers to remove the battery 300. When removing 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 remove 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-capable 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. Further, referring to 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 that encapsulates the battery 300. Without tools, the blister outer cover 120 is not easy to open, thereby achieving a child-proof effect. Furthermore, a first limiting protrusion 131 is provided inside the inner cover 130. Referring to Figures 7 to 9, the shearing protrusion 121 is provided outside the outer cover 120, and the second supporting protrusion 122 is provided inside the outer cover 120. A recessed portion 125 is provided on the outer cover 120 at a position corresponding to the first limiting protrusion 131, thereby forming a second limiting protrusion 126 inside the outer cover 120. The second limiting protrusion 126 is used to limit the position of the battery tape 310. Therefore, the cooperation between the first limiting protrusion 131 and the second limiting protrusion 126 prevents the battery 300 and the battery tape 310 from moving around. Preferably, the recessed portion 125 has a height of 1.5 mm, and the shearing protrusion 121 protrudes from the first supporting protrusion 132 by 2 mm in both the second and third directions.

[0046] Specifically, the bottom surface of the second limiting protrusion 126 is aligned with the top surface of the first limiting protrusion 131, and the second supporting protrusion 122 is provided at the edge of the second limiting protrusion 126, thereby facilitating 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 aligned and welded to ensure their relative position and mutual support. Specifically, the battery accommodating groove 111 includes a first accommodating groove 123 provided within the outer cover 120 and a second accommodating groove 133 provided within the inner cover 130; the battery removal groove 112 includes a first removal groove 124 provided within the outer cover 120 and a second removal groove 134 provided within the inner cover 130. Furthermore, the side walls of the first support protrusion 132 and the side walls of the second support protrusion 122 are both arc-shaped, which can improve the supporting strength between the first support protrusion 132 and the second support protrusion 122. Moreover, since the first support protrusion 132 is located at the junction between the battery accommodating groove 111 and the battery removal groove 112, the arc-shaped first support protrusion 132 can also guide the battery 300 to slide out.

[0047] Furthermore, referring to Figures 3 to 8 , the child-resistant battery packaging in this embodiment also includes a hanging tag 200. The blister housing 100 is mounted on the hanging tag 200, and information such as instructions can be printed on the hanging tag 200. Specifically, the hanging tag 200 is provided with a hanging hole 220 to facilitate hanging, selling, and storage. Furthermore, the blister housing 100 is turntable-shaped and can rotate relative to the hanging tag 200. The turntable shape of the blister housing 100 is aesthetically pleasing, and the rotatable turntable structure also adds interest to the packaging. Specifically, the hanging tag 200 is provided with a rivet hole 210. 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 enable the rotatability of the blister housing 100.

[0048] Furthermore, multiple battery retaining grooves 110 are distributed circumferentially around the blister housing 100. Referring to Figures 3 and 4, to remove a battery 300, the blister housing 100 can be rotated. When the shearing protrusion 121 rotates to the first edge of the elevator 200, the shearing protrusion 121 protrudes outward from the first edge of the elevator 200, while the first support protrusion 132 does not protrude beyond the first edge of the elevator 200. In this case, the first edge of the elevator 200 can be used as a cutting reference line, and shearing can be performed along the first edge of the elevator 200. This not only avoids shearing the first support protrusion 132, thus preventing the shearing process from being affected and damaging the first support protrusion 132, but also avoids shearing the elevator 200. Each time a battery 300 is removed, a shearing protrusion 121 can be rotated to the first edge of the elevator 200 for shearing. After multiple shearing cycles, the elevator 200 remains intact. After removing multiple batteries 300, the elevator 200 retains its original size, making it less likely to be lost and easier for consumers to find and access. 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 retaining groove 110 corresponding to the other shearing protrusions 121, maintaining the child-proof function. To further improve the convenience of cutting, the outer portion of the shearing protrusion 121 is flat. When removing the battery 300, the blister shell 100 is rotated. When the outer portion of the shearing protrusion 121 is approximately parallel to the first edge of the elevator 200, the shearing protrusion 121 can be cut along the first edge of the elevator 200, which can facilitate operation and eliminate the need for pre-set cutting reference lines on the elevator 200 during processing, thereby simplifying the processing of the battery 300 packaging structure.
