Description

Technical Field

[0001] This utility model relates to battery packaging. Background Technology

[0002] In recent years, with the development of portable electronic devices, the demand for batteries that power these electronic products has been increasing, and various studies have been conducted on the packaging structure and processes of commercially available batteries.

[0003] Figure 1 This is a schematic diagram illustrating the structure and logistics status of existing battery packaging. Most existing button battery packaging consists of a pre-formed outer shell (blister shell A) made from a rigid plastic sheet. During packaging, batteries C are typically inserted one by one into the blister shell A. The opening of the blister shell A is then manually glued to a cardboard box B using methods such as high-frequency welding, thus forming a hanging battery assembly.

[0004] Button batteries are easily swallowed by children, so to prevent this, a PET film is usually applied to the cardboard. However, the water absorption and expansion coefficients of PET film and paper are different. Therefore, in environments or areas with high temperature and humidity, the cardboard may warp, causing the product's appearance to deteriorate, and in some cases, the battery may even rust, thus reducing safety.

[0005] Furthermore, during supply, due to the thinness of the hanging-clip battery modules, even when neatly stacked, they can become scattered during transportation due to bumps. Therefore, it is necessary to place each group of hanging-clip battery modules into an inner box of roughly the same size as the module, and then place the inner box into an outer carton for transportation and sale. During distribution, the inner box needs to be removed from the outer carton, and the hanging-clip batteries need to be removed one by one and hung on the shelves for sale. Therefore, both the molding of the blister packs and the transportation and sales of multiple packaging objectively lead to low production and transportation efficiency in development, packaging, and distribution, and increase labor, time, and economic costs.

[0038] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings. The described embodiments are merely exemplary and can take many different forms. Furthermore, the drawings disclosed in this specification are, in principle, intended for schematic illustration. That is, the dimension ratios in the drawings may not necessarily match the actual dimension ratios, and the dimension ratios may not be consistent between different drawings. For the same components or constituent elements, reference numerals may sometimes be omitted.

The terms "inner side" and "outer side" are relative definitions with the battery as the reference frame. In other reference frames, the "inner side" may also be the outer side, and vice versa.

[0040] This embodiment of the battery packaging includes: a sealing member 11 formed of an integrated sheet or film assembly that houses a battery C, and a packaging shell 2 that houses two or more of the aforementioned sealing members 11. In one embodiment, two adjacent sealing members 11 are detachably joined and fixed together with each other and / or with the packaging shell 2. In this specification, a plurality of adjacent sealing members 11 that are detachably joined and fixed together are sometimes referred to as a sealing member group 1.

[0041] Figure 2 This is a schematic diagram of a battery packaging body according to one embodiment of the present invention. Figure 2 (a) is the front view. Figure 2 (b) is the right view. Figure 3 yes Figure 2 A perspective view of the battery package according to the illustrated embodiment. Wherein, Figure 2 (a) is the front view. Figure 2 (b) is the right view.

[0042] Figure 2 , Figure 3 In the battery packaging of the embodiment shown, each sealing component 11 houses one battery C, and every four sealing components 11 constitute a group of sealing components 1. The packaging shell 2 houses a group of sealing component groups 1.

[0043] The aforementioned battery C is not particularly limited and can be a primary or secondary battery, with any shape including cylindrical, square, and button-shaped. In terms of charge carriers, the aforementioned battery C can be a lithium battery, nickel-metal hydride battery, fluorine-ion battery, etc. In terms of electrolyte, the aforementioned battery C can be a liquid battery, semi-solid battery, solid battery, etc. In terms of internal structure, the aforementioned battery C can be wound, stacked, etc. From the perspective of better realizing the effects of this utility model, the aforementioned battery C is preferably a button battery.

[0044] <Sealing components>

[0045] The aforementioned sealing component 11 can be formed from an integrated sheet or membrane assembly.

[0046] <<Sheet assembly containing a waterproof paper substrate layer>>

[0047] As an example of the sheet-like or film-like component described above, it may be a sheet-like component comprising a waterproof paper substrate layer. Specifically, waterproof paper may be used to form the sealing member 11 described above.

[0048] As a waterproofing treatment, any known physical or chemical treatment can be used on the paper substrate layer, such as coating, transfer printing, or impregnation with waterproof materials. Combinations of these methods can also be employed, as long as they do not impair the effectiveness of this invention. This waterproofing treatment prevents moisture from entering the sealing component 11, protecting the battery C from rusting.

[0049] When a waterproof layer is applied to the paper substrate layer for waterproofing, the waterproof layer can be applied to one or both sides of the paper substrate layer as needed, without particular limitation. Preferably, the waterproof layer is applied to at least one side of the paper substrate layer that forms the inner side of the sealing component 11. This better prevents moisture from entering the sealing component 11 and protects the battery C from rusting.

[0050] In the aforementioned sheet assembly containing a waterproof paper substrate layer, a stress-buffering layer with stress-buffering portions can be provided directly or indirectly on the paper substrate layer, either directly or through any layer. From the outside, the stress-buffering portions may slightly protrude from the outer surface of the sheet assembly containing the waterproof paper substrate layer, or they may not slightly protrude from the outer surface of the sheet assembly containing the waterproof paper substrate layer. There are no particular limitations on the arrangement of the stress-buffering portions in the stress-buffering layer, as long as it does not impair the effect of this invention. For example, the stress-buffering portions may be arranged regularly throughout the entire stress-buffering layer. Not limited thereto, the stress-buffering portions may also be arranged irregularly throughout the entire stress-buffering layer. The stress-buffering portions may also not be distributed throughout the entire stress-buffering layer, but rather concentrated in areas prone to external stress during battery packaging, such as drops. Preferably, the stress-buffering portions are arranged regularly or irregularly throughout the entire stress-buffering layer. This is advantageous from the perspective of supplying the base material for the stress-absorbing layer, and can significantly reduce the risk of dents or breakage when subjected to external stresses such as drops, thereby improving safety. A non-limiting example of the base material for the stress-absorbing layer is, for instance, bubble wrap.

[0051] There are no particular restrictions on the use of bubble wrap, as long as it does not impair the effect of this invention; any commercially available product can be used.

[0052] In terms of material, bubble wrap can be made of polyolefins such as polyethylene (PE) and polypropylene (PP). From the perspective of better practicality and easier automation, PE film with bubble patterns (PE bubble wrap) is preferred.

[0053] Based on function, bubble wrap can be classified as antistatic bubble wrap, flame-retardant bubble wrap, color-printed bubble wrap, etc.

[0054] Based on their structure, bubble wrap can be a single-layer bubble wrap, or a composite bubble wrap such as a three-layer bubble wrap, a five-layer bubble wrap, or a seven-layer bubble wrap.

[0055] As the aforementioned stress buffer layer, it can be of any thickness, but preferably 0.3 mm or more, as long as it can encapsulate the battery C and maintain appropriate strength. This is advantageous from the perspective of improving buffering performance.

[0056] In the aforementioned sheet assembly containing a waterproof paper substrate layer, a reinforcing layer can be provided directly or indirectly on the paper substrate layer, either directly or through any other layer. This reinforcing layer is provided to improve tear resistance. This ensures that the packaging can only be opened with scissors or similar tools, preventing children from swallowing it. As a non-limiting example of the reinforcing layer, a film of any known material can be used, such as films of polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polystyrene (PS), etc.

[0057] In the aforementioned sheet-like assembly containing a waterproof paper substrate layer, a visual pattern layer can be directly or indirectly disposed on the paper substrate layer, either through any other layer. This visual pattern layer can be, for example, label content, a barcode, a QR code, etc.

[0058] <>

[0059] As another example of the sheet-like or film-like assembly described above, the sealing member 11 can be formed using a film-like assembly having a stress-buffering layer with stress-buffering portions. A non-limiting example of the base material for the stress-buffering layer is, for example, bubble wrap. Specifically, bubble wrap can be used to form the sealing member 11. In other words, the film-like assembly having a stress-buffering layer with stress-buffering portions described above can include bubble wrap as a substrate layer. Unless otherwise stated, any components / structures, materials, etc., not mentioned in this example can be used in accordance with the corresponding components / structures, materials, etc., described above in the section on "Sheet-like assemblies containing a waterproof paper substrate layer".

[0060] The sealing component 11 is formed by a membrane assembly with a stress-buffering layer and a stress-buffering portion. The performance requirements can be met with a thinner material, and there is no risk of battery dent or breakage after a drop. It is also low-cost (easy to package) and easier to assemble. Moreover, the membrane assembly with the stress-buffering layer and stress-buffering portion can be made of transparent material, so that the battery and the markings (logos) and other patterns commonly found on commercially available batteries can be observed from the outside, improving the appearance quality.

[0061] When the sealing member 11 is formed directly using a membrane assembly with a stress-buffered layer having stress-buffered portions, in addition to the stress-buffered layer having stress-buffered portions, a support layer may also be provided as needed. This support layer is located closer to the side housing the battery C, i.e., the inner side of the sealing member 11, compared to the stress-buffered layer having stress-buffered portions. By providing a support layer, the membrane assembly with the stress-buffered layer having stress-buffered portions can be given further strength and rigidity, improving the operability of using the membrane assembly with the stress-buffered layer having stress-buffered portions to automate the production of battery packaging, thereby increasing production efficiency and reducing costs. At the same time, the structural stability of the prepared battery packaging can also be improved, thereby further reducing the external stress on the battery caused by drops, transportation, and sales, and further enhancing safety.

[0062] The aforementioned support layer can be provided locally in a membrane assembly having a stress-buffered portion as needed. As an example of providing a support layer locally in a membrane assembly having a stress-buffered portion, the battery-receiving portion of the sealing member 11 may not have a support layer. In this case, when the sealing member 11 is formed, the battery is not wrapped by the support layer. Instead, the battery is wrapped by the stress-buffered layer, and the extensibility of the stress-buffered layer allows for sufficient wrapping and securing of the battery. When the battery packaging is subjected to external forces such as bumps during transportation and sales, the battery is prone to rotation, causing even the carefully aligned markings and patterns on the battery to become misaligned, affecting its appearance. However, by fully wrapping and securing the battery with the extensibility of the stress-buffered layer, the battery will not rotate when subjected to external forces such as bumps during transportation and sales. At the same time, the strength and rigidity of the support layer can be utilized to improve the operability of automated production of battery packaging using the membrane sealing component of this utility model, thereby improving production efficiency, reducing costs, and improving the structural stability of the prepared battery packaging. This further reduces the external stress on the battery caused by drops, transportation, and sales, and further enhances safety.

[0063] The aforementioned support layer can also be incorporated into the entire membrane assembly having a stress-buffered layer with a stress-buffering portion. In this case, when forming the battery package, the strength and rigidity of the support layer can be utilized more fully, improving the operability of automated production of battery packages using the membrane sealing component of this invention, thereby increasing production efficiency, reducing costs, and improving the structural stability of the prepared battery package. This further reduces external stresses on the battery caused by drops, transportation, and sales, further enhancing safety. In this case, it is preferable to use a support layer with appropriate flexibility, thereby properly securing the battery.

[0064] The material of the aforementioned support layer can be selected as needed, for example: polypropylene (PP), polyethylene terephthalate (PET), polystyrene (PS), paper, etc.

[0065] The membrane component with a stress-buffering layer containing stress-buffering portions can be a flat membrane or an irregularly shaped membrane. The membrane component with the stress-buffering layer containing stress-buffering portions can be processed, for example, by forming protrusions outwards, thereby allowing for more precise positioning and storage of batteries during storage, improving production efficiency.

[0066] It should be noted that known materials can be used to make the aforementioned support layer also function as a reinforcing layer that improves tear resistance, thus requiring only scissors or similar tools to open the packaging, preventing children from swallowing it. Furthermore, the aforementioned reinforcing layer can also be installed independently.

[0067] A reinforcing element may be provided as needed on a membrane assembly having a stress-buffering layer with a stress-buffering section.

[0068] As an example of reinforcement, reinforcing ribs can be provided, which can further improve the operability of automated production of battery packaging using the membrane sealing component of this utility model, thereby improving production efficiency, reducing costs, and improving the structural stability of the prepared battery packaging, thereby further reducing the external stress on the battery caused by drops, transportation and sales, and further improving safety.

[0069] The aforementioned reinforcing ribs can be boss-shaped reinforcing ribs, linear reinforcing ribs, or strip-shaped reinforcing ribs spanning the entire packaging shell 2. As reinforcing ribs, they can be achieved by thickening the supporting layer at the corresponding locations.

[0070] It should be noted that when reinforcing ribs are formed by thickening the support layer in the corresponding part, especially in the case where the support layer is provided in a part of a membrane assembly with a stress buffer layer having a stress buffer portion, i.e., where the part of the sealing member 11 that houses the battery C does not have a support layer, the battery can be fully wrapped and fixed by utilizing the extensibility of the stress buffer layer. Therefore, even if the support layer is thickened, the effect of suppressing the rotation of the battery when subjected to external forces such as bumps during transportation and sales will not be affected.

[0071] In the aforementioned membrane assembly having a stress-buffering layer with stress-buffering portions, a visual pattern layer can be directly or indirectly disposed on the stress-buffering layer having stress-buffering portions, either through any layer or by means of any other layer. This visual pattern layer can be, for example, label content, a barcode, a QR code, etc.

[0072] When using the sheet or film assembly of this embodiment, the sealing component 11 can be formed by the following process: the battery C is mechanically and automatically wrapped with the sheet or film assembly and then encapsulated to form the sealing component 11.

[0073] As an example of the above-mentioned package, two sheet-like or film-like components can be used, with their battery-containing side aligned with the battery C to be contained, and the two sheet-like or film-like components aligned and abutted against each other, and then packaged.

[0074] The sealing component 11 can also be formed by the following process: pre-forming a sheet or film component into, for example, a bag shape by mechanical automation, placing the battery C into the bag, and then sealing the bag opening to form the sealing component 11.

[0075] Encapsulation can be performed using any known method, such as hot pressing. Hot pressing can form the hot-pressed part 12, which can better fix the battery C and reduce the thickness of the sealing component 11, saving storage space and improving storage efficiency.

[0076] Vacuum sealing can also be performed simultaneously as needed. This allows for a further reduction in the thickness of the sealing component 11, saving storage space, and better preventing moisture from entering the sealing component 11, thus protecting the battery C from rusting.

[0077] In this embodiment, the sealing component 11 is formed by an integrated sheet or film assembly, so even if it is exposed to moisture in a high humidity environment, the stress is uniform throughout, and it will not warp due to different water absorption expansion coefficients as seen in existing paper cards.

[0078] <Sealing component assembly>

[0079] Figure 2 , Figure 3 In the battery package of the illustrated embodiment, every four sealing members 11 constitute a group of sealing members 1. The adjacent four sealing members 11 in the group of sealing members 1 are separably engaged and fixed together.

[0080] Such a sealing component assembly 1 can be formed, for example, by the following process: using two large sheet-like or film-like assemblies, aligning their battery-containing side with four batteries C to be housed, aligning and abutting the two sheet-like or film-like assemblies together, and then sealing them. Afterwards, using a processing tool such as a serrated mold, an easy-tear portion 14 and four sealing components 11 are formed at appropriate locations.

[0081] Figure 2 , Figure 3 In the embodiment shown, the sealing component group 1 includes four sealing components 11, but it is not limited to this and the number can be set arbitrarily according to the needs.

[0082] Figure 2 , Figure 3 In the embodiment shown, the four sealing components 11 in the sealing component group 1 are laterally separable and fixed together, but not limited thereto, they can also be longitudinally separable and fixed together.

[0083] Although not illustrated, such a sealing component assembly 1 can be formed, for example, by pre-forming a sheet or film component into, for example, a bag shape using automated machinery, placing the battery C into the bag, and then sealing the bag opening to form a sealing component 11. Multiple sealing components 11 are formed by repeating this process, and the multiple sealing components 11 can be separably joined and fixed together using known means such as adhesive layers.

[0084] like Figure 2 , Figure 3 As shown, the sealing component assembly 1 may be provided with a connecting portion 13 as needed. Through the connecting portion 13, multiple sealing component assemblies 1 can be joined and fixed together, for example, like a sticky note, or the sealing component assembly 1 can be joined and fixed to the packaging shell 2 described later.

[0085] <Packaging Shell>

[0086] The packaging shell 2 can accommodate two or more of the aforementioned sealing components 11 as needed, without any particular restrictions.

[0087] Figure 2 , Figure 3 In the embodiment shown, the packaging shell 2 houses an array of sealing component assemblies 1. The sealing component assemblies 1 adjacent to the packaging shell 2 can be detachably joined and fixed together, for example, via a joint 13. As a non-limiting example, although not shown, the detachable joint 13 that joins and fixes the sealing component assemblies 1 adjacent to the packaging shell 2 to the packaging shell 2 may also be provided with an easy-tear portion as needed.

[0088] The side of the packaging shell 2 can be provided with a window 21, so that the internal situation can be observed without opening the packaging shell 2.

[0089] Hanging clips 23 can be provided on the packaging shell 2. Therefore, without removing the sealing component assembly 1, the packaging shell 2 can be directly hung on the shelf for sale, saving the trouble of removing and hanging each battery individually as with traditional hanging batteries, thus saving labor and time costs.

[0090] The packaging shell 2 can be easily removed by omitting the front 22 or by providing a tear line, which are known easy-to-remove methods. In this embodiment, adjacent sealing component assemblies 1 are detachably joined and fixed together with each other, and with the packaging shell 2, so they will not fall apart even without the front 22. Moreover, by omitting the front 22 or by providing an easy-to-remove method, the front 22 can be easily removed without removing the sealing component assembly 1 from the packaging shell 2, allowing for a direct view of the product. This eliminates the hassle of removing and hanging each battery individually on a shelf, as is done with traditional hanging batteries, saving labor and time costs.

[0091] With the above configuration, the sealing component assembly 1 can be securely fixed and stored. After being neatly stacked, it will not become scattered due to bumps during transportation, thus eliminating the need for an inner box for storage. Moreover, when the battery C is to be used, the easy-tear part 14 and the joint part 13 can be torn open as needed to remove the sealing component 11.

[0092] It should be noted that, Figure 2 , Figure 3 The battery packaging shown is merely one embodiment of this invention. Although not shown, multiple sealing components 11 may also be stored independently in the packaging shell 2 without being joined and fixed together.

[0093] The above describes some embodiments of the present invention, but is not limited to the above embodiments. Various modifications can be made without departing from the spirit of the present invention.

[0094] The advantages and improvements of this invention will be readily understood by those skilled in the art upon reading this specification, and therefore the scope of this invention is not limited to the foregoing typical examples and specific details. Thus, various modifications can be made to this invention without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
