Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of product packaging, in particular to a packaging structure. Background Art
[0002] Some products are usually packaged by folding packaging materials into a packaging box. For example, for a six-pack of canned drinks, a hard paper packaging material is folded into a cuboid structure with both ends penetrated to wrap the six-pack of cans. Then, a buckle is arranged at one end of the paper sheet, and a card slot is arranged at the other end. Both the buckle and the card slot are directly formed by bending along a preset crease on the paper sheet. As Figure 8 Shown in the figure is an existing paper package buckle. A group of buckles is set as two card-connecting pieces 30 separated in the middle. The two card-connecting pieces correspond to two card slots, and there is a reinforcing rib between the two card slots. The two card-connecting pieces are inserted into the two card slots for clamping and cooperation. However, when the card-connecting pieces are inserted into the card slots, they will be squeezed by the reinforcing rib. Especially when their positions are not very accurate, it is easy to break the reinforcing rib, resulting in the paper package not being firmly clamped and the products being scattered. Summary of the Utility Model
[0003] In order to solve the above problems existing in the prior art, the utility model provides a packaging structure with more convenient and stable buckle connection.
[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0005] A packaging structure includes a sheet-shaped packaging material body with preset creases. The packaging material body is folded along the creases to form a packaging box in a cubic state. At least one group of buckles is arranged at one end of the packaging material body, and a clamping part that is clamped and cooperated with the buckles is arranged at the other end of the packaging material body; the clamping part is configured as two card slots, and a reinforcing rib is formed between the two card slots. The buckle includes two card-connecting pieces, and an avoidance gap with a width smaller than that of the reinforcing rib is arranged between the two card-connecting pieces, so that when the two card-connecting pieces are inserted into the two card slots, the card-connecting pieces can be smoothly inserted into the card slots without damaging the reinforcing rib.
[0006] By adopting the above technical scheme, the two card-connecting pieces in a group of buckles are isolated by the avoidance gap, so that when the card-connecting pieces are inserted into the card slots, the area of the card-connecting pieces located inside the avoidance gap can be more deformed and avoided to pass through the reinforcing rib, thus not damaging the reinforcing rib. At the same time, the existence of the avoidance gap enables the width of the reinforcing rib to be designed larger, further increasing the connection strength.
[0007] Preferably, the two card-connecting pieces in the buckle have the same shape and are symmetrically distributed, and the two card slots in the clamping part have the same shape and are symmetrically distributed. The symmetrical distribution makes the force more uniform when the card-connecting pieces are inserted into the card slots.
[0008] Preferably, the clamping piece is directly punched and formed on the packaging material body, and one end of the clamping piece is integrally connected to the packaging material body; the clamping groove is directly punched and formed on the packaging material body. The clamping piece and the clamping groove are directly punched and formed on the packaging material body, which makes the finishing processing and manufacturing more convenient.
[0009] Preferably, the width of the clamping groove decreases sequentially from inside to outside, and the width of the reinforcing rib increases sequentially from inside to outside. The inner end of the clamping groove has a large width, which is convenient for the clamping piece to penetrate into the clamping groove from the inner end of the clamping groove. When packaging items after the clamping piece passes through the clamping groove, the items generate pressure on the packaging box from the inside, causing the clamping piece to move outward to the outer end (the end with a small width) of the clamping groove, thereby further preventing the clamping piece from disengaging from the clamping groove and making the connection more stable and reliable.
[0010] Preferably, both sides of the avoidance gap are parallelly distributed, the width of the avoidance gap is greater than or equal to 2 mm, and the width of the avoidance gap is less than the minimum width of the reinforcing rib.
[0011] Preferably, the packaging material body includes a first connecting surface, a first side surface, a top surface, a second side surface, and a second connecting surface that are continuously distributed in sequence. The buckle is arranged on the first connecting surface, and the clamping portion is arranged on the second connecting surface; when the packaging material body is folded into a packaging box and connected through the buckle and the clamping portion, the first side surface and the second side surface are distributed facing each other, and the first connecting surface and the second connecting surface overlap to form the bottom surface of the packaging box.
[0012] Preferably, inclined transition surfaces are provided between the first connecting surface and the top surface, and between the second connecting surface and the top surface. Corner folding pieces for corner wrapping are provided between the two ends of the transition surface and the first connecting surface, and between the two ends of the transition surface and the second connecting surface. The transition surface can better fit the packaged product and prevent the edges and corners of the packaging box from being deformed under pressure.
[0013] Therefore, the utility model has the beneficial effect of more convenient and stable snap connection. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the technical problems to be solved, technical solutions and beneficial technical effects of the present utility model clearer, the present utility model will be further described in detail below in conjunction with the drawings and multiple exemplary embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model, rather than to limit the protection scope of the present utility model.
[0023] It should be understood that in this text, expressions such as "first", "second", etc. are only for descriptive purposes, and should not be construed as indicating or implying relative importance, nor should they be construed as implicitly indicating the quantity of the indicated technical features. Features defined with "first" and "second" may explicitly or implicitly include at least one such feature.
[0024] Such as Figures 1-7 A packaging structure as shown includes a sheet-shaped packaging material body 1 provided with creases in advance. The packaging material body 1 is folded according to the creases to form a packaging box 2 in a cubic state. At least one set of buckles 3 is provided at one end of the packaging material body 1, and a clamping portion 4 that is clamped and matched with the buckle 3 is provided at the other end of the packaging material body 1; the clamping portion 4 is configured as two card slots 40, and a reinforcing rib 41 is formed between the two card slots 40. The buckle 3 includes two clamping pieces 30, and a clearance 31 with a width smaller than that of the reinforcing rib 41 is provided between the two clamping pieces 30, so that when the two clamping pieces 30 are inserted into the two card slots 40, the clamping pieces 30 can be smoothly inserted into the card slots 40 without damaging the reinforcing rib 41.
[0025] The two clamping pieces 30 in the buckle 3 have the same shape and are symmetrically distributed. The two card slots 40 in the clamping portion 4 have the same shape and are symmetrically distributed. The width of the card slot 40 gradually decreases from the inside to the outside, and the width of the reinforcing rib 41 gradually increases from the inside to the outside. The two sides of the clearance 31 are parallelly distributed, the width of the clearance 31 is greater than or equal to 2 mm, and the width of the clearance 31 is smaller than the minimum width of the reinforcing rib 41.
[0026] In some embodiments, the width of the avoidance gap is set to 4 mm, the width of the inner end of the reinforcing rib is set to 5 - 6 mm, the width of the outer end of the reinforcing rib is set to 7 - 8 mm, and the clamping piece is inserted into the card slot from the inner end of the card slot. Due to the product pressure inside the packaging box, after the clamping piece is snapped into the card slot, it will move outward a certain position from the inner end of the card slot and move to the position where the width of the reinforcing rib is larger, thereby effectively preventing the clamping piece from coming out of the card slot.
[0027] In this embodiment, the clamping piece 30 is directly punched and formed on the packaging material body 1, and one end of the clamping piece 30 is integrally connected with the packaging material body 1; the card slot 40 is directly punched and formed on the packaging material body 1. As Figure 3 shown, along Figure 3 the contour of the clamping piece in Figure 4 is punched, and the remaining packaging material body at the avoidance gap between the two clamping pieces is called the filling piece 310; as Figure 4 shown, along Figure 5 and Figure 6 shown, the three sides of the card slot 40 are punched along the contour of the card slot, and the remaining packaging material body in the card slot 40 is called the reserved piece 400. After the clamping piece is snapped into the card slot, as
[0028] shown, the filling piece abuts against the bottom surface of the reinforcing rib, and the reserved piece 400 presses on the clamping piece, so that the clamping piece in the card slot is not easily separated from the card slot, and the connection between the two is more stable.
[0028] The packaging material body 1 includes a first connecting surface 100, a first side surface 101, a top surface 102, a second side surface 103, and a second connecting surface 104 that are continuously distributed in sequence. The buckle 3 is arranged on the first connecting surface 100, and the clamping part 4 is arranged on the second connecting surface 104; when the packaging material body 1 is folded into the packaging box 2 and connected through the buckle 3 and the clamping part 4, the first side surface 101 and the second side surface 103 are distributed facing each other, and the first connecting surface 100 and the second connecting surface 104 overlap to form the bottom surface of the packaging box 2. Two sets of buckles are arranged in this embodiment, and two sets of clamping parts are also arranged; in order to further increase the connection reliability, in some embodiments, auxiliary clamping pieces 32 for auxiliary clamping are also arranged at both ends of the first connecting surface, and auxiliary card slots 42 adapted to the auxiliary clamping pieces are arranged at both ends of the second connecting surface.
[0029] Inclined transition surfaces 105 are provided between the first connecting surface 100 and the top surface 102, and between the second connecting surface 104 and the top surface 102. Corner folding pieces 106 for corner wrapping are provided between both ends of the transition surface 105 and the first connecting surface 100, and between both ends of the transition surface 105 and the second connecting surface 104. In some embodiments, the packaging material body usually adopts a paper material or a bendable plastic sheet.
[0030] Combined with the attached drawings, the principle of the present invention is as follows: As Figure 1 shown is the unfolded state diagram of the packaging material body. When in use, it is folded along the crease intoFigure 5 The state of the cubic packaging box shown, and then insert the snap-in piece into the card slot; the avoidance gaps between the snap-in pieces can better avoid the reinforcing ribs, so that when the snap-in piece is inserted into the card slot, the reinforcing ribs will not be damaged; after the snap-in piece is inserted from one end of the card slot, it will move towards the narrow end of the card slot, thereby further preventing the snap-in piece from coming out of the card slot, and the connection is more stable and reliable.
