The packaging structure 100 is described below in conjunction with Figures 1-3E The packaging structure 100 is described below in conjunction with
[0031] ReferenceFigure 1 and Figure 2 The packaging structure 100 in the embodiment includes an inner box 110, a cover plate 120, and two rail portions 130.
[0032] The inner box 110 defines a receiving space, which can be used to accommodate the packaged object. The upper surface of the inner box 110 is open, and the packaged object can enter the receiving space from the upper surface of the inner box 110 or be taken out from the receiving space. In different embodiments of the utility model, the shape of the inner box 110 and the shape of the inner receiving space are not limited. Specifically, in some embodiments of the utility model, as shown in Figure 1 , the inner box 110 can be roughly set in a cuboid shape, wherein the cuboid shape includes five surfaces, and the upper surface is open. In some embodiments, the upper surface of the inner box 110 can be set to be partially open.
[0033] As shown in Figure 3A , according to the preferred embodiment of the utility model, the inner box 110 can be made of cardboard or gray board blank through cutting, folding, and pasting.
[0034] In some embodiments, a filler can be arranged in the receiving space or a limiting piece matching the shape of the packaged object can be arranged to reduce the probability of the packaged object shaking in the receiving space and to protect the packaged object.
[0035] The cover plate 120 can be covered on the upper surface in the inner box 110. Preferably, the cover plate 120 can completely cover the upper surface of the inner box 110, and when the cover plate 120 is covered on the upper surface of the inner box 110, the receiving space of the inner box 110 is closed. When the cover plate 120 is removed from the upper surface of the inner box 110, the receiving space of the inner box 110 is opened.
[0036] As shown in Figure 1 and Figure 2 , the cover plate 120 in the embodiment includes a plurality of parallelly arranged connecting pieces 121, the plurality of connecting pieces 121 are rotatably connected, and the whole of the cover plate 120 can be bent and deformed. In some embodiments, the direction in which the plurality of connecting pieces 121 are arranged in parallel is parallel to the axis direction of the bending and deformation of the cover plate 120, for example Figure 1 , the direction perpendicular to the paper surface.
[0037] In the embodiment, the connecting piece 121 has a certain stiffness, and the plurality of connecting pieces 121 are connected in parallel, which can be used to close the receiving space of the inner box 110. When it is necessary to open the receiving space of the inner box 110, the plurality of connecting pieces 121 can be rotated at the positions of mutual connection, and the whole of the cover plate 120 is bent.
[0038] As shown in Figure 1As shown, according to a preferred embodiment of the present invention, the cover plate 120 further includes a connecting portion 122, on which a plurality of connecting pieces 121 are arranged in parallel and side by side, and the connecting portion 122 is capable of bending and deforming. The cover plate 120 can deform the connecting pieces 121 in the elongation direction (…). Figure 2 The connecting part 122 has a certain stiffness in the vertical direction shown in the figure, which can resist impact and pressure to a certain extent. The connecting part 122 bends and deforms around the extension direction of multiple connecting pieces 121 to open the accommodating space of the inner box 110.
[0039] In some embodiments, the connecting portion 122 may be a flexible paper material, and the plurality of connecting pieces 121 may be a paper material with a certain stiffness, and the plurality of connecting pieces 121 are disposed on the connecting portion 122, for example, the plurality of connecting pieces 121 are pasted on the connecting portion 122.
[0040] In other embodiments, the connecting piece 121 and the connecting portion 122 can be integrally formed. For example... Figure 3B As shown, the cover plate 120 is made of cardboard, with multiple cuts made along a parallel direction on one side of the cardboard, but not cut in the thickness direction. The cut side of the cardboard forms a continuous piece 121, and the uncut side forms a connecting portion 122. This embodiment simplifies the processing of the cover plate 120. In some preferred embodiments, the uncut side of the cardboard can be reinforced to reduce the risk of damage to the cover plate 120, for example, by applying tape to the uncut side of the cardboard.
[0041] The packaging structure 100 also includes two track sections 130, which are disposed on the outside of the inner box 110, i.e., on the outer side of the inner box 110 away from the accommodating space. The two track sections 130 are respectively located near two opposite sides of the inner box 110. Specifically, for example, the inner box 110 is approximately cuboid in shape, and the two track sections 130 are disposed on the sides of the long side of the inner box 110 in a top view. Preferably, the track sections 130 are located near the outer side of the inner box 110; for example, the two track sections 130 are respectively attached to the outer side of the long side of the inner box 110. Preferably, the two track sections 130 are made of paper material and are pasted onto the outer side of the inner box 110. The two track sections 130 are disposed opposite each other, and the two sides of the cover plate 120 cooperate with the two track sections 130.
[0042] Specifically, the track section 130 includes an upper track 131, a lower track 132, and a connecting track 133. The upper track 131 is located above the upper edge of the inner box 110, and the lower track 131 is located below the lower edge of the inner box 110. The connecting track 133 is disposed between the upper track 131 and the lower track 132, and the connecting track 133 communicates with the upper track 131 and the lower track 132. That is, the cover plate 120 can move from the upper track 131 to the lower track 132 via the connecting track 133.
[0043] In some embodiments, the track portions 130 can be made of paper material. For example Figure 3C As shown, the track portions 130 are made of thick gray board, and grooves are excavated or recesses are formed at preset positions in the gray board to form the upper track 131, the lower track 132, and the connecting track 133. Alternatively, in other embodiments, the track portions 130 are made of multiple pieces of paper board, and grooves are formed on some of the paper boards, and the multiple pieces of paper board are pasted after being stacked to form the upper track 131, the lower track 132, and the connecting track 133.
[0044] In this embodiment, the two ends of the continuous piece 121 in the cover plate 120 in the length direction are respectively matched with the two track portions 130, for example, are lapped on the upper track 131, the lower track 132, and the connecting track 133 in the two track portions 130, so that the cover plate 120 can move along the upper track 131, the lower track 132, and the connecting track 133, for example, the cover plate 120 can be manually pushed and pulled.
[0045] Further, when the continuous piece 121 in the cover plate 120 moves to the upper track 131, the cover plate 120 can cover the accommodation space of the inner box 110. When the cover plate 120 moves along the upper track 131 and the connecting track 133 to the lower track 132, the cover plate 120 opens the accommodation space of the inner box 110.
[0046] The packaging structure 100 in this embodiment can realize manual push-pull opening and closing of the accommodation space, improves the user experience, and the structures in the packaging structure 100 in this embodiment can all be made of paper material, which enriches the opening and closing forms of the paper packaging structure. The following will be described in combination with specific embodiments and Figures 3A-3E The packaging structure 100 made of paper material is described.
[0047] In some embodiments, as shown in Figure 1 and Figure 3C As shown, the connecting track 133 is arc-shaped. In this embodiment, the upper track 131, the lower track 132, and the connecting track 133 form a U-shaped track, and the inner box 110 is located inside the U-shaped track. The inside of the U-shaped track means Figure 1 As shown in the perspective view in
[0048] As shown in Figure 1 The cover plate 120 can slide along the U-shaped track between the upper track 131 and the lower track 132. For example, when it is needed to open the accommodation space of the inner box 110, the cover plate 120 is manually pushed to the left side Figure 1 in the left side) to move the cover plate 120 to the lower track 132 to open the accommodation space. When it is needed to close the inner box 110, the cover plate 120 is manually pushed to the right side Figure 1The cover plate 120 is manually pulled to the right side in the figure to cover the upper surface of the inner box 110.
[0049] In some embodiments of the present application, the track portion 130 comprises two connecting tracks 133. The two connecting tracks 133 are respectively arranged on both sides of the upper track 131 and the lower track 132. The upper track 131, the lower track 132 and the two connecting tracks 133 form a ring-shaped track. The cover plate 120 can move along the ring-shaped track, and the opening and closing direction of the accommodating space of the inner box 110 is not limited.
[0050] Preferably, a limiting member is arranged on the cover plate 120 and / or the track portion 130, which can limit the movement distance of the cover plate 120 along the upper track 131, the lower track 132 and the connecting track 133, and prevent the cover plate 120 from completely sliding to the lower track 132, so that the accommodating space of the inner box 110 cannot be closed.
[0051] According to the preferred embodiment of the present application, the connecting pieces 121 in the cover plate 120 have gaps therebetween. When the cover plate 120 is bent and deformed, the gaps between the connecting pieces 121 can absorb the deformation on the inside of the bending of the cover plate 120, and prevent the cover plate 120 from being damaged due to extrusion.
[0052] In other embodiments, the connecting pieces 121 are arranged in the connecting portion 122 and on one side of the inner box 110 there. As shown in the figure, the connecting pieces 121 are arranged on the outer side of the connecting portion 122. When the cover plate 120 is bent and deformed along the upper track 131, the lower track 132 and the connecting track 133, the connecting pieces 121 are expanded to the outer side, and the adjacent connecting pieces 121 will not extrude each other. Figure 1 According to the preferred embodiment of the present application, as shown in the figure, the width of the connecting track 133 is greater than the thickness of the cover plate 120, so that the connecting pieces 121 can move along the connecting track 133 while keeping flat. Further, the width of the connecting pieces 121 (indicating the size of the connecting pieces 121 in the direction perpendicular to the extending direction) is matched with the curvature of the connecting track 133, so that the cover plate 120 can be bent along the connecting track 133.
[0053] Figure 1 In some embodiments, the curvature of the connecting track 133 is also related to the distance between the upper track 131 and the lower track 132, or related to the height of the inner box 110. In the case of meeting the distance between the upper track 131 and the lower track 132, the curvature of the connecting track 133 is preferably reduced to reduce the risk of jamming of the cover plate 120 in the connecting track 133. Correspondingly, the greater the curvature of the connecting track 133, the smaller the width of the connecting pieces 121. In order to improve the structural strength (stiffness) of the cover plate 120, the curvature of the connecting track 133 is preferably reduced.
[0054] In some embodiments, the curvature of the connecting track 133 is also related to the distance between the upper track 131 and the lower track 132, or related to the height of the inner box 110. In the case of meeting the distance between the upper track 131 and the lower track 132, the curvature of the connecting track 133 is preferably reduced to reduce the risk of jamming of the cover plate 120 in the connecting track 133. Correspondingly, the greater the curvature of the connecting track 133, the smaller the width of the connecting pieces 121. In order to improve the structural strength (stiffness) of the cover plate 120, the curvature of the connecting track 133 is preferably reduced.
[0055] According to a preferred embodiment of the present invention, the length of the cover plate 120 is set to be greater than the length of the upper track 131, so that the cover plate 120 can completely cover the upper surface of the inner box 110. Furthermore, the length of the cover plate 120 is set to be less than the sum of the lengths of the lower track 132 and the connecting track 133, so as to fully open the upper surface of the inner box 110 and prevent the lower track 132 from obstructing further opening of the cover plate 120.
[0056] like Figure 1 As shown, in a preferred embodiment of the present invention, the packaging structure 100 further includes an outer box 140. The outer box 140 is disposed outside the track portion 130, covering the inner box 110 and the track portion 130. The upper surface of the outer box 140 is at least partially open, and the open portion of the upper surface of the outer box 140 corresponds to the open portion of the upper surface of the inner box 110, so that the accommodating space of the inner box 110 can be opened from the open position on the upper surface of the outer box 140, for example, by a user operating the cover 120 from the open position. In this embodiment, the outer box 140 not only protects the inner box 110 and the track portion 130, but also covers the track portion 130, which is beneficial to the aesthetic appearance of the packaging structure 100. According to a preferred embodiment of the present invention, the outer box 140 is made of folded paper material. The blank of the outer box 140 is as follows... Figure 3D As shown, it is made by cutting and folding cardboard.
[0057] In some embodiments, the open portion of the upper surface of the outer box 140 can also be sealed using other structures. For example, the outer box 140 can be plastic-sealed, or a transparent plastic sheet can be affixed to the open portion of the upper surface of the outer box 140.
[0058] In some embodiments of this utility model, the track portion 130 and the outer surface of the inner box 110 are bonded and fixed together, and / or the inner surface of the outer box 140 is bonded and fixed together. For example, bonding the track portion 130 between the outer side of the inner box 110 and the inner side of the outer box 140 helps to improve the structural stability of the packaging structure 100. In some embodiments, a connecting structure is also provided between the two track portions 130, for example, connecting the two track portions 130 on the outside of the connecting track 133, which can further improve the structural stability of the packaging structure 100.
[0059] According to some embodiments of the present invention, the outer box 140 completely covers the top of the track section 130. The outer box 140 can decorate the track section 130, which is beneficial for the track section 130 to select materials with higher structural strength but poorer appearance, such as gray board.
[0060] like Figure 3EAs shown, in the preferred embodiment of the present application, the packaging structure 100 further comprises a face paper 150. The face paper 150 can be covered on at least one of the inner surface of the inner box 110, the outer surface of the outer box 140 or the outer surface of the track part 130, preferably, the face paper 150 is pasted on at least one of the inner surface of the inner box 110, the outer surface of the outer box 140 or the outer surface of the track part 130. The face paper 150 not only can decorate the packaging structure 100, improve the aesthetic degree of the packaging structure 100, but also can shape the inner box 110 and the outer box 140, utilize the structural strength of the face paper 150 to make the blank of the inner box 110 and the outer box 140 keep the three-dimensional shape, save the material and reduce the weight of the packaging structure 100.
[0061] Finally, it should be noted that: the above only for the embodiment of the present application, and not for the purpose of limiting the present application, although the foregoing detailed description of the present application is made with reference to the foregoing embodiments, for the person skilled in the art, it still can be modified, or the equivalent replacement of part of the technical features recorded in the foregoing embodiments.
