Description

Technical Field

[0001] The utility model relates to a double-layer packaging box, and more specifically, to a double-layer packaging box capable of expanding a display area. Background Art

[0002] At present, most gift boxes are over-packed and have relevant international standards and regulations, especially when they are used to display small and medium-sized samples, so the display space is obviously limited. However, during the display and terminal sales process, small and medium-sized samples of cosmetics need to be placed at the same time to improve the display effect.

[0003] In order to expand the display space, the gift box is usually designed to be a sliding double-layer structure. However, the previous double-layer sliding gift boxes usually adopt a drawer-type structure. Although the space for storage can be expanded, the storage space of the two layers cannot be displayed at the same time.

[0004] In addition, this drawer-type double-layer structure only uses a sliding structure in the first and second layer boxes, and no components are set to limit the sliding movement. Therefore, the sliding distance is easily offset, and the neatness of the two layers of the box body cannot be guaranteed, which greatly affects the appearance and usage experience of the packaging box.

[0005] Therefore, how to provide a double-layer packaging box that can expand the display space while avoiding the deviation of the two-layer box body and keeping it neat becomes a technical problem that needs to be solved urgently. Utility Model Content

[0067] Various embodiments of the present invention will now be described in detail, examples of which are shown in the accompanying drawings. Although the present invention is described in conjunction with exemplary embodiments, it should be appreciated that this specification is not intended to limit the present invention to the exemplary embodiments described below. On the contrary, the present invention is intended to cover not only these exemplary embodiments, but also various alternative forms, modified forms, equivalent forms and other embodiments that may be included within the spirit and scope of the present invention as defined by the appended claims.

[0068] The following, combined Figures 1 to 8 The double-layer packaging box 1 of the present invention is described.

[0069] Here, for the convenience of explanation, three mutually orthogonal directions are set as the left-right direction, the up-down direction, and the front-back direction, and the specific directions are shown in the figure.

[0070] (Overall structure of double-layer packaging box 1)

[0071] like Figure 1 As shown, the double-layer packaging box 1 of the present invention mainly includes a first box body 11 and a pair of second box bodies 12 as a whole. The first box body 11 is arranged below the double-layer packaging box 1, and the pair of second box bodies 12 are formed into exactly the same shape and are arranged above the first box body 11 in a manner opposite to each other.

[0072] The above-mentioned first box body 11 and the above-mentioned pair of second box bodies 12 are both formed into a roughly rectangular shape, and the length of the above-mentioned first box body 11 in the left-right direction is roughly equal to the sum of the lengths of the above-mentioned pair of second box bodies 12 in the left-right direction, and the length of the above-mentioned first box body 11 in the front-to-back direction is also roughly equal to the length of the above-mentioned pair of second box bodies 12 in the front-to-back direction.

[0073] With such a configuration, the pair of second case bodies 12 can be stacked on the first case body 11 and formed into a larger rectangular parallelepiped shape together with the first case body 11 .

[0074] (Specific structures of the first box body 11 and the second box body 12)

[0075] Below, refer to Figure 2 and Figure 3, the specific structures of the first box body 11 and the second box body 12 of the double-layer packaging box 1 of the present invention are described.

[0076] Figure 2 and Figure 3 It is an exploded stereogram of the double-layer packaging box 1 of the present invention when viewed from one angle and another angle.

[0077] like Figure 2 and Figure 3 As shown, the first box body 11 is mainly composed of a first front side plate 111 , a first rear side plate 112 , a first left side plate 113 , a first right side plate 114 and a first bottom plate 115 .

[0078] The first front plate 111 and the first rear plate 112 are formed into identical rectangular shapes and are arranged opposite to each other in the front-rear direction, and the first left plate 113 and the first right plate 114 are formed into identical rectangular shapes and are arranged opposite to each other in the left-right direction.

[0079] A space with openings at both ends is enclosed and formed by the first front side plate 111 , the first rear side plate 112 , the first left side plate 113 , and the first right side plate 114 .

[0080] The first bottom plate 115 closes one end of the space with both ends open in the up-down direction to form a first storage space DYSN for storing and displaying articles, and the other end of the space with both ends open is formed as a first opening DYKK.

[0081] Similarly, the pair of second box bodies 12 are respectively composed of a second front side plate 121 , a second rear side plate 122 , a second left side plate 123 , a second right side plate 124 and a second bottom plate 125 .

[0082] Since the pair of second case bodies 12 are formed in substantially the same shape and are arranged opposite to each other in the left-right direction, the second case body 12 located on the left side is described below as an example.

[0083] The second front plate 121 and the second rear plate 122 are formed into identical rectangular shapes and are arranged opposite to each other in the front-rear direction, and the second left plate 123 and the second right plate 124 are formed into identical rectangular shapes and are arranged opposite to each other in the left-right direction.

[0084] A space with openings at both ends is enclosed and formed by the second front side plate 121 , the second rear side plate 122 , the second left side plate 123 and the second right side plate 124 .

[0085] The second bottom plate 125 closes one end of the space with both ends open in the up-down direction to form a second storage space DESN for storing and displaying articles, and the other end of the space with both ends open is formed as a second opening DEKK.

[0086] By forming the first storage space DYSN in the first box body 11 and the second storage space DESN in the pair of second box bodies 12, it is possible to expand the space for displaying and storing commodities.

[0087] In addition, if Figure 2 As shown, a cover body GT for closing the second storage space DESN is also provided on the pair of second box bodies 12, and the cover body GT is mainly composed of a cover plate GTA and a flap GTB.

[0088] The cover plate GTA is formed into a shape substantially the same as the second bottom plate 125 of the second box body 12, and one side thereof is connected to the second left side plate 123 in a manner rotatable relative to the second box body 12, thereby being able to cover the second opening DEKK and close the second storage space DESN.

[0089] A flap GTB is connected to the other side of the cover plate GTA opposite to the side connected to the second left plate 123. The flap GTB is formed into a rectangular shape substantially the same as the second right plate 124 and is connected to the cover plate GTA in a manner that allows it to rotate relative to the cover plate GTA.

[0090] Therefore, when the second storage space DESN is to be closed, the cover plate GTA closes the opening of the second storage space DESN, and the flap GTB is attached to the second right side plate 124 .

[0091] In addition, magnetic adsorption structures adapted to each other are respectively arranged at corresponding positions of the above-mentioned flip plate GTB and the second right side plate 124, so that the above-mentioned flip plate GTB and the second right side plate 124 can maintain the fitting state when they are in contact with each other, thereby maintaining the closed state of the second storage space DESN.

[0092] In addition, the cover plate GTA may be provided with ribbons, signs or other decorations, which can be used as handles to facilitate opening the cover body GTA.

[0093] (Connection structure of the first box body 11 and the second box body 12)

[0094] Below, refer to Figure 3 , the sliding connection structure in which the first box body 11 and the pair of second box bodies 12 are slidably connected to each other is described.

[0095] like Figure 2 and Figure 3 As shown, the pair of second box bodies 12 are disposed above the first box body 11 in a manner that they can slide relative to the first box body 11 .

[0096] The sliding connection structure in which the first box body 11 and the pair of second box bodies 12 are slidably connected to each other is mainly composed of a first guide member 11 b provided on the first box body 11 and a second guide member 12 b provided on the second box body 12 .

[0097] like Figure 2 As shown, a first extension portion 11 a is circumferentially disposed on the inner circumference of the first opening DYKK of the first box body 11 , and the first extension portion 11 a extends upward from the inner circumference of the first opening DYKK of the first box body 11 in the vertical direction.

[0098] On two sides of the first extending portion 11 a in the front-rear direction, first guides 11 b are provided at positions on the opposite side to the first opening DYKK so as to protrude toward the outer peripheral side in the front-rear direction.

[0099] Assuming that the thickness of the first front side plate 111 and the first rear side plate 112 of the first box body 11 in the front-to-rear direction is h1, the thickness of the first extension portion 11a is h2, and the thickness of the first guide member 11b is h3, then the thickness of the first extension portion 11a and the first guide member 11b is formed to be h1>h2+h3.

[0100] like Figure 2 As shown, a second extension portion 12a is circumferentially arranged on the outer peripheral side of the second box body 12, and the second extension portion 12a extends downward in the up and down directions from the outer peripheral side of the second bottom plate 125 of the second box body 12, and forms a semi-enclosed structure except for the side where the second right side plate 124 is located.

[0101] On two sides of the second extension portion 12 a in the front-rear direction, second guides 12 b are provided at positions on the opposite side to the second bottom plate 125 so as to protrude toward the inner peripheral side in the front-rear direction.

[0102] The first guide member 11b and the second guide member 12b are both formed into rectangular strips, and the directions of the two are completely consistent.

[0103] In addition, the thickness of the four side plates constituting the first case body 11 is equal to the thickness of the four side plates constituting the second case body 12 .

[0104] Assuming that the thickness of the second extension portion 12a of the second box body 12 in the front-rear direction is h2' and the thickness of the second guide member 12b is h3', the thickness of the second extension portion 12a and the second guide member 12b is formed to be h2+h2'+h3'=h1 and h2+h3+h2'=h1.

[0105] Assuming that the height of the first extension portion 11a of the first box body 11 in the vertical direction is t1, the height of the first guide member 11b is h2, the height of the second extension portion 12a of the second box body 12 in the vertical direction is t1', and the height of the second guide member 12b is h2', then the heights of the second extension portion 12a and the second guide member 12b are formed to be h2+h2'=t1=t1'.

[0106] With such a configuration, the first case body 11 is slidably connected to the second case body 12 via the first guide 11 b of the first case body 11 and the second guide 12 b of the second case body 12 so as to be slidable relative to the second case body 12 .

[0107] like Figure 4 and Figure 5 As shown, the pair of first box bodies 11 slide relative to the second box body 12 , and the pair of first box bodies 11 can be used as top covers of the second box body 12 .

[0108] When the pair of second boxes 12 slide away from each other, the first opening DYKK of the first box 11 opens and displays the first storage space DYSN. When the pair of second boxes 12 move away from each other, the first opening DYKK of the first box 11 closes and seals the first storage space DYSN.

[0109] In addition, when the first opening DYKK is fully opened to expose the first storage space DYSN, the second storage space DESN is exposed by opening the lid bodies GT of the pair of second box bodies 12, thereby further expanding the storage space for display.

[0110] Furthermore, since the pair of second box bodies 12 are formed in completely identical shapes, when the double-layer packaging box 1 is fully opened, the double-layer packaging box 1 appears very neat as a whole, which can significantly improve the display effect.

[0111] In addition, return to Figure 2 ,like Figure 2 As shown, abutment portions DJB are formed in the first extension portion 11a of the first box body 11 at positions close to the first front side plate 111 and the first rear side plate 112 respectively. The abutment portions DJB are formed at positions close to one side of the flip plate GTB and extend in the left-right direction.

[0112] Assuming that the left-right lengths of the first front side plate 111 and the first right side plate 114 of the first box body 11 are s1, the left-right lengths of the second front side plate 121 and the second rear side plate 122 of the second box body 12 are s2, and the sum of the left-right lengths of the abutment portion DJB is s3, then the abutment portion DJB is formed as s2+s3=s1.

[0113] In addition, magnetic adsorption materials capable of attracting each other are respectively disposed in the contact portions DJB of the pair of first case bodies 11 .

[0114] Therefore, when closing the double-layer packaging box 1, the pair of first box bodies 11 can be attracted together by the provided magnetic adsorption material, and the abutment portion DJB can withstand the impact force generated by the collision of the pair of first box bodies 11 when closing, thereby preventing damage to the first box bodies 11 and extending their service life.

[0115] (Limiting structure of the first box body 11 relative to the second box body 12)

[0116] Below, refer to Figures 6 to 8 , the limiting structure when a pair of second box bodies 12 slide relative to the first box body 11 is described.

[0117] like Figure 6 As shown, a protrusion TCB is provided at a position of the second bottom plate 125 of the second box body 12 close to the second rear side plate 122 . The protrusion TCB is formed in a substantially rectangular shape and protrudes downward from the second bottom plate 125 .

[0118] Back to Figure 3 ,like Figure 3 As shown, the long side direction of the protrusion TCB is along the front-rear direction, and the protrusion TCB is set as a first limiting portion, which limits the second box body 12 from falling off relative to the first box body 11 when a pair of second box bodies 12 slide away from each other.

[0119] like Figure 7 As shown, the portion of the second box body 12 close to the second extension portion 12a and close to the second left side plate 123 is formed as a second limiting portion, which limits the moving distance of the pair of second box bodies 12 in the direction of approaching each other when the pair of second box bodies 12 slide towards each other, thereby preventing the second box bodies 12 from moving beyond the limit.

[0120] In addition, if Figure 6As shown, a notch QK is formed at a substantially middle position in the left-right direction of the first extension portion 11 a of the first box body 11 , and the notch QK is used for inserting the flap GTB of the cover body GT of the second box body 12 .

[0121] The width and depth of the notch QK are formed to match the size of the flap GTB of the cover body GT.

[0122] Specifically, assuming that the depth of the notch QK of the first box body 11 in the vertical direction is d1, the width in the left and right direction is d2, the thickness of the flap GTB of the cover body GT in the left and right direction is d3, the width of the first right side plate 114 in the vertical direction is d4, and the thickness in the left and right direction is d5, then the notch QK of the first box body 11 is formed as d1+d4=d3 and d2=2*d5.

[0123] By configuring in this way, the notch QK can be used as a third stopper, and when the pair of second case bodies 12 slide toward each other and reach a limit distance, the third stopper can lock the second case body 12 at the limit position.

[0124] In addition, if Figure 8 As shown, when the double-layer packaging box 1 needs to be closed, the flap GTB is added into the above-mentioned gap QK and fits tightly with the second right side plate 124 through the magnetic adsorption structure as described above, so that the closed state can be firmly maintained, and at this time the entire double-layer packaging box 1 is formed into a neat rectangular shape, with a neat appearance and easy to carry.

[0125] (Technical Effect)

[0126] As described above, in the double-layer packaging box 1 of the present invention, a pair of second box bodies 12 slide relative to the first box body 11, and the space for displaying and storing goods can be expanded by forming a first storage space DYSN in the first box body 11 and a second storage space DESN in the second box body 12.

[0127] In addition, the first limiting portion can prevent the second box body 12 from falling off from the first box body 11 when the pair of second box bodies 12 slide away from each other.

[0128] In addition, the second limiting portion can prevent the pair of second boxes 12 from exceeding the maximum limit distance when moving in the direction of approaching each other.

[0129] Furthermore, by means of the third limiting portion, when the pair of second case bodies 12 move to a maximum limiting distance in a direction in which the pair of second case bodies 12 approach each other, the second case bodies 12 can be held at the limiting position.

[0130] Through the first to third limiting portions, the space for display and storage can be expanded by the double-layer packaging box while preventing the two layers of the box body that slide relative to each other from moving beyond the limit or sliding relative to each other.

[0131] (Other Modifications)

[0132] Although the structure and working principle of the utility model are described above in combination with the preferred embodiments, ordinary technicians in the technical field should realize that the above examples are only for illustration and do not constitute a limitation of the utility model. The utility model can be modified and varied within the spirit of the claims, and these modifications and variations will fall within the protection scope of the utility model.

[0133] For example, in the present invention, an example is shown in which the abutting portion DJB is provided on the first extending portion 11 a of the first case body 11 , but the present invention is not limited thereto and may not include the abutting portion DJB.

[0134] For example, in the present invention, a notch QK is formed approximately in the middle of the first extension portion 11a of the first box body 11 in the left-right direction as an example of a third limiting portion, but the present invention is not limited thereto and may not include a third limiting portion.

[0135] For example, in the present invention, it is shown that the thickness of the first extension portion 11a of the first box body 11 is less than the thickness of the side panels constituting the first box body 11, but the present invention is not limited to this and may also be greater than the thickness of the side panels constituting the first box body 11 as long as it is convenient for sliding connection with the second box body 12.

[0136] For example, in the present invention, an example is shown in which a pair of second box bodies 12 are formed into shapes that are exactly the same as each other, but the present invention is not limited to this.
