Description

Technical Field

[0001] The utility model relates to an outer packaging structure, in particular to a packaging structure for accommodating objects. Background Art

[0002] There is a common blister packaging structure in the market at present, which is to seal the product between a blister formed by a transparent plastic sheet and a paper card.

[0003] However, once the plastic and paper are heat-sealed together, it means that the two materials are difficult to completely separate, which means that after the product is taken out, the outer packaging will become a composite material and cannot be effectively recycled and reused.

[0004] In addition, due to the different thermal shrinkage rates of paper and plastic, heat sealing of this type of packaging often results in an uneven packaging surface and curled edges.

[0005] In addition, consistent with the user experience, for this type of packaging that glues plastic and paper together, since the plastic is difficult to tear, it is difficult for users to open the packaging with the help of tools, and they often need to use tools such as utility knives and scissors. Utility Model Content

[0006] The purpose of the utility model is to provide a full paper packaging structure, in which the entire packaging structure is made of paper without containing plastic materials, thereby facilitating the recycling and reuse of the packaging, reducing adverse effects on the environment, improving the flatness of the outer packaging, and making it easy for users to open the packaging.

[0007] In order to achieve the above-mentioned purpose, the utility model proposes a full paper packaging structure, which includes:

[0008] A first paper card and a second paper card overlapping with the first paper card, wherein the overlapping area of ​​the first paper card and the second paper card includes a first area and a second area; wherein the first area has at least one cavity for accommodating an object protruding from the plane where the overlapping area is located; in the second area, a bonding layer is provided between the first paper card and the second paper card.

[0011] Furthermore, in some other embodiments of the present invention, for a single cavity, a portion thereof is formed on the first paper card, and another portion thereof is formed on the second paper card.

[0012] Furthermore, in some embodiments of the present invention, a connection between the cavity and the first paper card or the second paper card is provided with an arc chamfer.

[0013] Furthermore, in some embodiments of the present invention, the size and / or shape of the cavity is completely matched with the accommodated object.

[0014] Furthermore, in some embodiments of the present invention, the outer surface of the cavity has a printing layer.

[0015] Furthermore, in some embodiments of the present invention, the overlapping area of ​​the first paper card and the second paper card further includes a third area, and a portion of the first paper card in the third area and / or a portion of the second paper card in the third area is provided with an opening structure.

[0016] Furthermore, in some embodiments of the present invention, the opening structure partially overlaps with the cavity.

[0017] Furthermore, in some embodiments of the present invention, a window is provided at a position corresponding to the mold cavity; or a window is provided on the mold cavity.

[0018] Furthermore, in some embodiments of the present invention, when the first region has at least two cavities, a splitting structure is provided in an overlapping region between two adjacent cavities.

[0019] Furthermore, in some embodiments of the present invention, the overlapping area also includes a hollow fourth area, and the fourth area is configured as a hanging hole.

[0020] Furthermore, in some embodiments of the present invention, the hanging hole includes an arc portion.

[0021] Further, in some embodiments of the present invention, when the first area has at least two cavities, the hanging hole extends in the arrangement direction of the at least two cavities to correspond to each cavity.

[0039] The full paper packaging structure of the present invention will be further explained and illustrated below in conjunction with the accompanying drawings and specific embodiments of the specification. However, such explanation and illustration do not constitute an improper limitation on the technical solution of the present invention.

[0040] For the common blister packaging structure, since it is formed by heat-sealing plastic and paper card together, it is difficult to completely peel off the two materials, making it impossible to effectively recycle and reuse the packaging materials. In addition, due to the different thermal shrinkage rates of paper and plastic, heat-sealing this kind of packaging often leads to uneven packaging surfaces and curled edges. In addition, since plastic is difficult to tear, it is difficult for users to open the packaging with the help of tools when disassembling it, and they often need to use tools such as utility knives and scissors to open the packaging.

[0041] In order to solve the above problems, the utility model proposes a full paper packaging structure in one embodiment.

[0042] Figure 1 A schematic diagram of the split structure of the all-paper packaging structure of the utility model in one embodiment is shown.

[0043] Figure 2 A schematic diagram showing the structure of the all-paper packaging structure of the utility model in one embodiment

[0044] like Figure 1 and Figure 2 As shown, in some embodiments, the all-paper packaging structure includes:

[0045] A first paper card 11 and a second paper card 12 overlapped with the first paper card 11, wherein the overlapped area of ​​the first paper card 11 and the second paper card 12 includes a first area 1 and a second area 2; wherein the first area has at least one cavity 13 protruding from the plane where the overlapped area is located, and the cavity 13 is used to accommodate the packaged object, such as a planer blade; in the second area 2, there is a bonding layer 21 between the first paper card 11 and the second paper card 12. Figure 2 The dark part in the figure represents the second area 2 with the laminating layer 21. That is, the first paper card 11 and the second paper card 12 are bonded together by the laminating layer in these dark areas. However, the first area with the cavity 13 does not have the laminating layer.

[0046] It should be noted that although Figure 1 and Figure 2 The all-paper packaging structure is shown to have two cavities, but it is also feasible to have only one cavity, that is, a packaging structure can only contain one object. The number of cavities is only related to the number of objects contained.

[0047] In this way, the object is enclosed in the cavity by the all-paper packaging. In various specific embodiments, the shape and size of the cavity can be set to fully match the shape and size of the packaged object. For example, Figure 1 A cavity is shown by way of example in which a planer blade is accommodated.

[0048] Since both outer packaging layers of the encapsulated object are made of paper, the packaging structure can be recycled after the object is taken out without causing adverse effects on the environment. In addition, when the user wants to take out the object, the packaging structure can be directly torn open without the help of tools.

[0049] In addition, in some embodiments of the present invention, the shape and size of the cavity 13 are adapted to the object to be accommodated, which is not only conducive to positioning the object more stably in the cavity and preventing the object from shaking in the cavity, but also helps the user to identify the shape of the object from the outside. Figure 1 There is no viewing window on the cavity shown, but the user can still recognize that a flat blade is contained therein through the outer contour of the cavity.

[0050] In some more specific embodiments, the outer surface of the cavity 13 may also have a printing layer or a coating layer, and the printing layer may be configured to display the appearance of the object contained in the cavity, such as including color, pattern, and logo.

[0051] Furthermore, in some more specific embodiments, the bonding layer can be set as a heat-sealing adhesive layer. The heat-sealing adhesive layer refers to an adhesive layer formed by a material that has no adhesive force at room temperature but has adhesive force after being treated by a heat-sealing process. In some more specific embodiments, the heat-sealing adhesive layer can be a blister oil layer. In other embodiments, the heat-sealing adhesive layer can also be heat-sealing glue.

[0052] Of course, in other embodiments, the laminating layer may also be a glue layer having adhesive force at room temperature.

[0053] In some more specific embodiments, Figure 1 As shown, for a single cavity 13, it is entirely formed (for example, preformed by mold pressing) on ​​the second paper card 12, and the first paper card 11 is entirely flat without a cavity.

[0054] In some other specific implementations, a single cavity may be completely formed on the first paper card (for example, pre-formed by mold pressing), and the second paper card is then in a plane as a whole without the cavity.

[0055] In addition, in some other embodiments, Figure 3 As shown, for a single cavity, a portion 131 thereof is formed on the first paper card 11 , and another portion 132 is formed on the second paper card 12 , that is, when the first paper card 11 and the second paper card 12 are bonded together, they jointly form the cavity 13 .

[0056] Continue reading Figure 3 In some more specific embodiments, a circular chamfer 133 is provided at the junction of the mold cavity 13 and the first paper card 11 or the second paper card 12. The setting of the circular chamfer makes it more convenient to take and put objects in the mold cavity.

[0057] like Figure 1 and Figure 2 As shown, in some more specific embodiments, the overlapping area of ​​the first paper card 11 and the second paper card 12 further includes a third area 3, and the second paper card 12 is provided with an opening structure 31 in the third area. In order to enable the opening structure to be opened smoothly, the third area 3 has no laminating layer.

[0058] Of course, in some other alternative implementations, an opening structure may also be provided on the first paper card.

[0059] In addition, in Figure 3 In the illustrated embodiment, the first paper card 11 and the second paper card 12 are each provided with an opening structure 31 in the third region.

[0060] In some more specific embodiments, the opening structure may be a tear strip formed by pre-processing tear lines on the first paper card and / or the second paper card.

[0061] Figure 4 The figure shows a state where the opening structure of the all-paper packaging structure of the utility model is opened in one embodiment.

[0062] like Figure 4 As shown, the utility model can further improve the convenience of opening the all-paper packaging structure by providing an opening structure 31. Compared with not providing an opening structure, it is more labor-saving for the operator to open the package by tearing the opening structure.

[0063] In some more specific embodiments of the present invention, Figure 1 and Figure 3As shown, the opening structure 31 partially overlaps with the cavity 13. This arrangement allows, once the package is opened by the opening structure, the objects placed in the cavity are directly exposed to the outside, thereby facilitating the operator to take out the objects.

[0064] Of course, in other optional implementations, the opening structure may also be configured not to overlap with the cavity. In this case, after the opening structure is opened, the object needs to be further poured out of the cavity.

[0065] In some more specific embodiments of the present invention, a hollow window may be provided at the position corresponding to the cavity.

[0066] like Figure 5 As shown, in this embodiment, the cavities 13 are all formed on the second paper card 12, and a hollow window 14 is provided on the first paper card 11 at a position corresponding to the cavity.

[0067] In some other implementations, the hollowed-out window may also be directly disposed on the cavity.

[0068] By providing the viewing window, the user can intuitively see the objects placed in the packaging structure.

[0069] Figure 6 The structure of an all-paper packaging structure with a split structure in one embodiment is shown.

[0070] like Figure 6 As shown, in some more specific embodiments, when the first region has at least two cavities 13, the overlapping region between two adjacent cavities 13 is provided with a split structure 22. The overlapping region between two adjacent cavities also belongs to the second region and has a bonding layer.

[0071] In some more specific embodiments, the splitting structure may be a tear line disposed at the same position on the first paper card and the second paper card.

[0072] Figure 7 The state where the full paper packaging structure with a split structure is split is shown.

[0073] like Figure 6 and Figure 7 As shown, when in use, the objects contained in each cavity in the full paper packaging structure can be torn off separately through the split structure 22, and the objects are still sealed in independent packages. When one of the objects is opened for use, the other objects are still in a sealed state, which is convenient for storage and improves the convenience of use.

[0074] Continue reading Figure 1 , Figure 2 , Figure 6 and Figure 7 In some embodiments of the present invention, the overlapping area of ​​the first paper card 11 and the second paper card 12 further includes a hollow fourth area 4, which is configured as a hanging hole 41, so as to facilitate placing or storing the all-paper packaging structure in a hanging manner. In some more specific embodiments, the hanging hole 411 includes a circular arc portion 411 located in the middle.

[0075] In particular, when the first region has at least two cavities to accommodate at least two objects, the hanging hole 41 extends the arm portion 412 in the arrangement direction of the at least two cavities. Figure 8 As shown, when the objects contained in each cavity are separated individually by the separation structure, they can still achieve the hanging function by extending the arms 412 to each other.

[0076] Fig. 9 A schematic diagram of the split structure of a full paper packaging structure with a folding structure in one embodiment is shown.

[0077] Fig.10 A schematic diagram of the overall structure of a full paper packaging structure with a folding structure in one embodiment is shown.

[0078] like Fig. 9 As shown, in some embodiments, the overlapping area of ​​the first paper card 11 and the second paper card also includes a fifth area 5, and the fifth area 5 where the folding structure 51 is located does not have a laminating layer (ie Fig. 9 (not light in color) Fig. 9 The dark area in the figure represents the second area 2 having the adhesion layer.

[0079] like Fig. 9 and Fig.10 As shown, the first paper card 11 and the second paper card 12 both have a folding structure 51 in the fifth area. Fig. 9 and Fig.10 In the embodiment shown, the folding structure 51 can rotate around the folding line P pre-pressed on the first paper card 11 and the second paper card 12, so as to fold over a certain angle relative to the plane where the overlapped area is located, such as Fig.11 As shown, the two folding structures 51 are relatively opened. In this case, the two folding structures 51 form the base of the entire paper packaging structure, which is convenient for it to be placed upright on the placement plane. When it is not necessary to place it on a flat surface, the folding structure can be reset to the plane where the overlapping area is located, so that the paper packaging structure has the advantages of occupying a small space and saving transportation and storage costs.

[0080] In some other embodiments, the folding structure may be provided on only one of the first paper card and the second paper card. In this case, a folded folding structure and another paper card without a folding structure may also form a support leg, but the full paper packaging structure is placed at an angle in this case instead of being placed vertically on the placement plane.

[0081] In addition, if Fig. 9 , Fig.10 and Fig.11 As shown, in some more specific embodiments, when the first paper card 11 and the second paper card 12 both have the folding structure 51, the two folding structures are also provided with a sub-folding structure 511 that can be folded relative to the folding structure 51, and the two sub-folding structures 511 are connected to each other after being folded, for example, Fig.12 As shown, the slits provided on the sub-folding structures are inserted into each other to fix the relative opening angle or distance of the two folding structures 51, so as to prevent the two folding structures from being over-opened and causing instability of the entire packaging structure.

[0082] Of course, in some other embodiments, the relative opening angle or distance of the two folding structures can be fixed by other structures, for example, a paper hook is provided on each folding structure, and the fixation is achieved by overlapping the two paper hooks. Alternatively, the sub-folding structure is made to abut against the folding structure on the opposite side, so as to achieve fixation.

[0083] The all-paper package described in the utility model is suitable for containing various objects, such as various small power tools, hand tools and various accessories thereof. Those skilled in the art can set the shape, size and number of the cavity according to actual needs to adapt to various tools and their accessories.
