Description

Technical Field

[0001] This utility model relates to a paper protective shell and the apparatus for manufacturing the same, and more particularly to a paper protective shell for use in clip-on packaging and the apparatus for manufacturing the paper protective shell. Background Technology

[0002] How to make a product as environmentally friendly as possible from production to sales is a topic of great importance to companies around the world.

[0003] Plastic blister packs, with their advantages of being lightweight, transparent, and easy to mold, have long been a favorite packaging material for small products among many manufacturers. They are often used in conjunction with single-sheet paper cards (see reference 1). Figure 1 The blister packs are then bonded together to form the final outer packaging. This type of packaging technology is mature, and changing it would require significant R&D and material costs. Therefore, for many manufacturers, plastic blister packs and the processes they employ are not easily replaceable.

[0004] However, the final product combining plastic and paper is difficult to separate, and consumers cannot easily recycle them separately and dispose of them as general waste, which inevitably causes a lot of unavoidable pollution.

[0005] In order to achieve the goal of being environmentally friendly, some companies want to use paper or other recyclable materials to replace plastic blister packs, for example... Figure 1 The plastic blister pack is replaced with a paper blister pack 2. However, the inventor discovered that this assembly method may be disassembled during transportation, and the genuine product may be replaced and re-glued without being noticed by the consumer. It is even easy to disassemble and steal the product from just one side.

[0006] To improve the above-mentioned defects, such as Figure 2 As shown, the inventor attempted to solve the problem of disassembly of the paper blister pack 2 (paper protective shell) by using a clip-on, folding paper card 3 packaging. During the process, it was found that this clip-on, folding paper card, combined with the existing paper blister pack 2, can still open one side by applying force in the direction of the arrow. This form still has the problem that it is easy to steal and replace the genuine product from one side and restore it without being noticed by the consumer.

[0007] In view of this, there is a need for packaging that is environmentally friendly and can prevent theft or replacement from one side, especially paper protective shells that cannot be restored to their original state after disassembly. Utility Model Content

[0008] One objective of this invention is to provide a paper protective shell for clip-on packaging, which enables the entire packaging to be recycled and makes the product less susceptible to theft or replacement during transportation, and in particular, the paper protective shell is not easily maintained in its original state after disassembly.

[0009] To achieve the aforementioned objective, the paper protective shell for clip-on packaging provided by this utility model comprises a paper card body. The paper card body has a central section, two long side sections, and two short side sections, each of which is integrally connected to the central section. Each of the two long side sections has a first box wall portion and a first clamping portion connected to the first box wall portion. Each of the two short side sections has a second box wall portion and a second clamping portion connected to the second box wall portion. Each of the first clamping portions has a first fastening angle, and each of the second clamping portions has a second fastening angle, with the first and second fastening angles each having a matching angle.

[0010] As described above, the paper protective shell provided by this utility model offers an intermediate section adaptable to various product sizes, where the product is placed after the paper protective shell is completed. A first clamping portion and a second clamping portion are provided to cooperate with the clamp-type packaging to seal the paper protective shell. Utilizing the matching angles of a first snap-fit ​​angle of the first clamping portion and a second snap-fit ​​angle of the second clamping portion, the paper protective shell is held together in the clamp-type packaging, making it difficult to create an opening by applying force from one side. If forcefully pushed, creases or tears will directly form at the first and second snap-fit ​​angles, making them irreparable. This prevents others from stealing or replacing the product from either side during transportation.

[0011] To achieve the aforementioned objective, this utility model further provides an apparatus for manufacturing paper protective cases as described above, comprising a paper protective case forming station. The paper protective case forming station includes an upper fixture that matches the outer contour shape of the paper card body and a lower fixture corresponding to the upper fixture. The upper fixture is adapted to transport at least one paper card body above the lower fixture and align it with at least one forming opening included in the lower fixture.

[0012] As described above, the device provided by this utility model has an upper fixture and a lower fixture specifically for forming the paper protective shell, each corresponding to an outer contour shape of the paper protective shell. The upper fixture can transport at least one paper card body to the upper part of the lower fixture and align the at least one paper card body with at least one forming opening included in the lower fixture.

[0013] In one embodiment, the length of each of the first box wall portions of the paper protective shell gradually increases from the middle block in a distance direction.

[0014] In one embodiment, the length of each of the second box walls of the paper protective shell gradually increases from the middle block in a distance direction.

[0015] In one embodiment, each of the first snap-fit ​​angles of the paper protective shell is a convex angle.

[0016] In one embodiment, each of the second fastening angles of the paper protective shell is a concave angle.

[0017] In one embodiment, the angle of each of the first fastening angles of the paper protective shell is slightly larger than the angle of the second fastening angle.

[0018] In one embodiment, each of the two long-side sections and the two short-side sections of the paper protective shell has a first connection point with the middle section, where each has a parallel double K-line. A second connection point between each of the first box wall portions and the first clamping portion has a half-tangent.

[0019] In one embodiment, each of the half-cut lines of the paper protective shell occupies approximately 80% of the second connection extending from a central point, and the two sides of the second connection adjacent to the half-cut lines are cut off.

[0020] In one embodiment, the upper fixture of the apparatus for manufacturing paper protective shells as described above includes at least one upper suction nozzle, and the lower fixture includes at least one lower suction nozzle. The at least one upper suction nozzle is movably in contact with an inner surface of the intermediate block, and the at least one lower suction nozzle is in contact with an outer surface of the intermediate block. The at least one upper suction nozzle and / or the at least one lower suction nozzle are adapted to apply a downward force to complete the forming of the paper protective shell.

[0021] The above description is not intended to limit the present invention, but merely to provide a general overview of the technical problems that the present invention can solve, the technical means that can be adopted, and the technical effects that can be achieved. Based on the accompanying drawings and the description of the following embodiments, those skilled in the art will be able to further understand the details of the various embodiments of the present invention.

[0066] The following will describe specific embodiments of the present invention; however, without departing from the spirit of the present invention, the present invention can be practiced in many different forms, and the scope of protection of the present invention should not be construed as limited to those stated in the specification.

[0067] The terms "first" and "second" used in this article are for the purpose of describing and distinguishing each element or component, rather than indicating that the elements or components described have a necessary order or priority.

[0068] For clarity, the distances between lines in the accompanying drawings may be exaggerated, and their relative positions are not limited by this.

[0069] Please see Figure 3The diagram shows a plan view of the paper protective shell 5 before molding. The paper card body 10 includes a central block 100, two long side blocks 120, and two short side blocks 140. The two long side blocks 120 are arranged opposite each other, and the two short side blocks 140 are also arranged opposite each other. The long side blocks 120 and the short side blocks 140 are arranged alternately and adjacent to each other, and the two long side blocks 120 and the two short side blocks 140 are integrally connected to the central block 100. The entire paper card body 10 is cut from the same paper card. The two long-side blocks 120 each have a first box wall portion 122 and a first clamping portion 124 connected to the first box wall portion 122 by its long side. The two short-side blocks 140 each have a second box wall portion 142 and a second clamping portion 144 connected to the second box wall portion 142 by one side. Each first clamping portion 124 has a first fastening angle 124a, and each second clamping portion 144 has a second fastening angle 144a. The first fastening angle 124a and the second fastening angle 144a each have a matching angle A1 and A2, which can interlock with each other after the paper protective shell 5 is formed, preventing them from overlapping and blocking each other, so that the two long-side blocks 120 and the two short-side blocks 140 cannot move toward the middle block 100 after forming.

[0070] In one embodiment, the paper card body 10 may have a thickness, which is selected according to different materials, to facilitate the protection of the product and maintain its shape and prevent deformation during impact after the paper protective shell 5 is formed. In this embodiment, the length L1 of each first box wall portion 122 may gradually increase from the middle block 100 in a direction away from the middle block 100, that is, the first box wall portion 122 is an isosceles trapezoid. The length L2 of each second box wall portion 142 may also gradually increase from the middle block 100 in a direction away from the middle block 100, also in an isosceles trapezoid, to facilitate forming.

[0071] In this embodiment, each first snapping angle 124a is a convex angle, and each second snapping angle 144a is a concave angle. Furthermore, the angle A1 of each first snapping angle 124a is slightly larger than the angle A2 of each second snapping angle 144a. This ensures that after the paper protective shell 5 is formed, they do not overlap but rather interlock and prevent the first clamping portion 124 and the second clamping portion 144 from moving towards the central block 100 (see reference). Figure 4 In one embodiment, the convex and concave corners can also be set in opposite directions.

[0072] In this embodiment, before the paper protective shell 5 is formed, each of the two long side blocks 120 and the two short side blocks 140 of the paper card body 10 has a first connection point C1 with the middle block 100, with parallel double K lines 11 (K lines are also called "creases" or "crims"). In one embodiment, the double K lines 11 are formed by reverse pressing (by the product approaching the creasing machine), so that the first connection point C1 can maintain a high yield during the automation process, presenting a clear and flat crease line and not easily damaged during the automated concave folding (concave folding towards an inner surface 12). The second connection points C2 between the first box wall 122 and the first clamping part 124 and between the second box wall 142 and the second clamping part 144 have a half-cut line 13 (shown as a single-dot dashed line in the figure, which does not represent a tear line), the half-cut line 13 extends from the inner surface 12 of the paper card body 10 towards an outer surface 14 (please refer to...). Figure 5 The cutting line 13 is formed by cutting the second connection point C2, which occupies approximately 80% of the area extending from the center of the second connection point C2 (for example, if the length of the second connection point C2 of the short side block 140 is preset to 23.8 mm, the half-cut line 13 can be 19.8 mm), or up to 90% (if the length of the second connection point C2 of the long side block 120 is preset to 69 mm, the half-cut line 13 can be 63 mm). The two sides of the second connection point C2 adjacent to the half-cut line 13 are cut off when the paper card body 10 is cut out in the process, forming a break line 15, so that the second connection point C2 can be easily folded inward (folded inward towards the outer surface 14) during the automated forming process, and when forming the paper protective shell 5, the first clamping part 124 and the second clamping part 144 can partially pass through the break line 15 to strengthen the fixing force after forming, and are not easily deformed when subjected to impact after packaging. In one embodiment, the second connection point C2 of the long side block 120 and the second connection point C2 of the short side block 140 have the same length of break line 15 (i.e., the lengths of break lines 15 at the eight locations are the same).

[0073] Please refer to Figure 4 As shown, after the paper card body 10 is formed into a paper protective shell 5, it will be placed in the opening of a clip-on paper card 8 to complete the clip-on packaging. Specifically, the clip-on paper card 8 can be a thick paper card with fold lines, which can be folded along the fold lines to clamp the first clamping part 124 and the second clamping part 144 of the paper protective shell 5 between the cards. In one embodiment, after the paper protective shell 5 is placed in the opening, the first clamping part 124 and the second clamping part 144 can be fixed in the opening by heat pressing, but whether heat pressing is performed and the processing method are not limited thereto.

[0074] from Figure 4It can be further understood that the first clamping portion 124 and the second clamping portion 144 of the paper card body 10 formed into the paper protective shell 5 do not overlap each other, so they will not interfere with the final folding of the clip-on paper card 8 and the completion of packaging. The first snapping angle 124a and the second snapping angle 144a abut against each other and may interlock slightly through the break line 15 when subjected to external force, so as to mitigate the impact (e.g., falling to the ground) and maintain the formed shape.

[0075] like Figure 5 As shown, if the paper protective case 5 is placed into the opening and the first clamping part 124 or the second clamping part 144 is pushed forcefully (for example, according to the direction of the straight arrow), creases or tears will be directly generated around the first snapping angle 124a or the second snapping angle 144a, which cannot be restored and can be easily identified as having been opened.

[0076] Please refer to the following: Figure 4 and Figure 6 The diagram shows a top view of the equipment 30 for manufacturing the paper protective case 5 as described above, which includes a paper protective case forming station 300. It may further include a card preparation station 400, a product placement station 500, and a packaging completion station 600. The card preparation station 400 positions the clip-on card 8; the paper protective case forming station 300 forms the paper protective case 5 by placing the card body 10 into the opening 9 of the positioned clip-on card 8; the product placement station 500 places the product (manually or automatically) into the formed paper protective case 5 in the opening 9 of the clip-on card 8; and the packaging completion station 600 folds the clip-on card 8 and performs heat pressing around it to complete the clip-on packaging. In other words, the equipment 30 can complete the clip-on packaging in one stop.

[0077] Figure 7 This is a schematic diagram illustrating a jig and a paper card body 10 being transported. Figure 8 The diagram illustrates the fixture and shows a clamp-type paper card 8 aligned with a forming opening 344. In this embodiment, the paper protective shell forming station 300 includes an upper fixture 320 (see reference) that matches the outer contour shape of the paper card body 10 when the paper protective shell 5 is not formed. Figure 7 ) and the corresponding jig 340 below jig 320 (see reference) Figure 8The upper fixture 320 is configured to transport at least one card body 10 above the lower fixture 340 and align the at least one card body 10 with at least one forming opening 344 included in the lower fixture 340. Specifically, the upper fixture 320 may include at least one upper suction nozzle 322, and the lower fixture 340 may include at least one lower suction nozzle 342. In this embodiment, the upper fixture 320 employs two upper suction nozzles 322, and the lower fixture 340 employs one lower suction nozzle 342 corresponding to one card body 10. The upper suction nozzle 322 movably first contacts the inner surface 12 of the intermediate block 100, applying a suction force to transport the card body 10 to the forming opening 344, and then applies a downward force to push the intermediate block 100 towards the lower suction nozzle 344. 42. The paper card body 10 located outside the forming opening 344 will be blocked by the shape of the forming opening 344. As the middle block 100 continues to be pushed downward, the first connection C1 and the second connection C2 will be concave. The first box wall 122 and the second box wall 142 will change from a flat state to a near-vertical state. When the outer surface 14 approaches or contacts the lower suction nozzle 342, the lower suction nozzle 342 can also apply a suction force to move the middle block 100 further downward, further improving the forming of the paper protective shell 5. Optionally, depending on the different paper card thicknesses, the lower suction nozzle 342 can also apply a downward force after applying a suction force to achieve a higher forming yield or the expected forming state.

[0078] In one embodiment, the upper fixture 320 and the lower fixture 340 can be configured to form multiple paper card bodies 10 in one step.

[0079] As described above, after the paper protective shell 5 provided by this utility model is formed, the first clamping part 124 and the second clamping part 144 can interlock without overlapping and block each other to prevent movement. Furthermore, they can slightly pass through the tear line 15 to strengthen the fixation after forming. Thus, when folded and clamped by the clip-on paper card 8 and subjected to impact after packaging, it is less prone to deformation. Moreover, if someone attempts to disassemble and steal the product from one side after forming, creases or tears will appear that cannot be repaired, making it easy to identify that the package has been opened. In other words, compared to traditional packaging, the paper protective shell 5 provided by this utility model allows for overall packaging recycling and makes the product less susceptible to theft or replacement during transportation.

[0080] The above embodiments are merely illustrative of the implementation of this utility model and to explain its technical features, and are not intended to limit the scope of protection of this utility model. Any changes or equivalent arrangements that can be easily made by those skilled in the art are within the scope of this utility model, and the scope of protection of this utility model shall be determined by the scope of the patent application.
