Abstract
Description
Technical Field
[0001] This application relates to logistics packaging technology, and more particularly to a foldable packaging box. Background Technology
[0002] Yogurt can be sold in multi-cup containers, such as single-layer four-cup yogurt or double-layer eight-cup yogurt. This multi-cup design makes it easy to share and avoids contamination or spoilage of leftover yogurt from a large container that has not been fully consumed after opening.
[0003] Currently, yogurt packaging boxes directly enclose and restrain single-layer four-cup yogurt or double-layer eight-cup yogurt. However, for multi-cup yogurt with three or more layers, the existing yogurt packaging boxes are not very effective at restraining them, and the yogurt in the middle layer can easily fall out of the packaging box from one side. Utility Model Content
[0004] This application provides a foldable packaging box to solve the technical problem in the related art that multi-cup materials are easy to fall out of the packaging box.
[0005] This application provides a foldable packaging box, comprising:
[0006] The cut piece body includes a base plate and a first plate and a second plate disposed on opposite sides of the base plate. Both the first plate and the second plate are foldable. The first plate and the second plate are configured to be joined together after folding to form a receiving cavity together with the base plate. The receiving cavity is used to accommodate at least three layers of material.
[0007] Wherein, at least one of the first plate and the second plate is provided with a limiting member, the limiting member being configured to be inserted into the receiving cavity when at least one of the first plate and the second plate is folded, and to be connected to at least one of the plurality of sub-materials interconnected in the intermediate layer material, so as to prevent the intermediate layer material from leaving the receiving cavity.
[0008] In some possible implementations, the limiting member is provided with a limiting hole for inserting the sub-material into the limiting member.
[0009] In some possible implementations, the number of limiting holes is at least two, and the limiting holes are used to match the sub-material.
[0010] In some possible implementations, the limiting member is provided with a notch that communicates with the limiting hole.
[0011] In some possible implementations, along the direction away from the first plate, the second plate includes a first side plate, a top plate, and a second side plate arranged in sequence, the folded first plate and the folded second side plate are located on the same plane, and the first plate and the second side plate are joined together.
[0012] In some possible implementations, the limiting member is located at one end of the first plate away from the second plate, a first crease is provided between the limiting member and the first plate, and the limiting member is configured to bend along the first crease toward the bottom plate.
[0013] In some possible implementations, the limiting member is disposed on the first side plate, the limiting member extends along the width direction of the first side plate, and the limiting member is located on one side of the middle of the first side plate.
[0014] In some possible implementations, a second crease is provided between the first plate and the bottom plate, a third crease is provided between the first side plate and the bottom plate, a fourth crease is provided between the top plate and the first side plate, and a fifth crease is provided between the top plate and the second side plate;
[0015] At least one of the first crease, the second crease, the third crease, the fourth crease, and the fifth crease is provided with a reinforcing rib that is recessed toward the receiving cavity, the reinforcing rib being used to engage with the material.
[0016] In some possible implementations, at least one of the first plate and the second plate is provided with a cutout portion for exposing a portion of the material.
[0017] In some possible implementations, the first plate and the second plate are bonded together by Velcro.
[0018] The folding packaging box provided in this application has a cut piece body as an integral plate. The limiting member is folded and formed with at least one of the first plate and the second plate. During the enclosing process of the packaging box, it is inserted into the receiving cavity and directly forms a physical connection with the middle layer material, preventing the middle layer material from falling out of the receiving cavity. As a result, the entire cut piece body does not require additional accessories or operations. A single folding operation can complete the snap-fit and fixation of the middle layer material at the same time as forming the packaging box, preventing the middle layer material from falling out of the packaging box. The operation is simple, convenient and efficient.
[0019] In addition, the limiting component is set on the cut piece body as an extension. The cut piece body can be formed by cutting and folding a single sheet of material, which helps to reduce the overall material cost and is suitable for large-scale production and application.

[0034] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation
[0035] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.
[0036] As mentioned in the background section, yogurt packaging boxes typically wrap around and constrain single-layer four-cup yogurt or double-layer eight-cup yogurt. However, for multi-cup yogurt with three or more layers, the existing yogurt packaging boxes are not effective at constraining the yogurt. Yogurt in the middle layer can easily slip off from one side of the packaging box, damaging the integrity of the packaging and affecting the product's display and the consumer's user experience.
[0037] Currently, multi-tiered yogurt cups with three or more layers are rare in the market, partly due to the immaturity of packaging technology. To ensure the packaging box effectively secures the multi-tiered yogurt cups, shrink film or tape is typically used, but this increases costs and is neither environmentally friendly nor aesthetically pleasing.
[0038] Based on the above description, one or more embodiments of this application provide a foldable packaging box. The cut piece body is an integral plate, and a limiting member is folded and formed with at least one of the first and second plates. During the enclosure process of the packaging box, it is inserted into the receiving cavity and directly forms a physical engagement with the middle layer material, preventing the material from falling out of the receiving cavity. Thus, the entire cut piece body does not require additional accessories or operations. A single folding operation can complete the engagement and fixation of one layer of material while forming the packaging box, preventing the material from falling out of the packaging box. The operation is simple, convenient, and highly efficient. In addition, the limiting member is set on the cut piece body as an extension. The cut piece body can be formed by cutting and folding a single sheet of material, which helps to reduce the overall material cost and is suitable for large-scale production and application.
[0039] The following description, in conjunction with the accompanying drawings, illustrates the folding packaging box of this application.
[0040] like Figure 1 As shown, the foldable packaging box of this application embodiment includes a cut piece body 100. The cut piece body 100 includes a base plate 110 and a first plate 120 and a second plate 130 disposed on opposite sides of the base plate 110. Both the first plate 120 and the second plate 130 can be folded. The first plate 120 and the second plate 130 are configured to be joined together after folding to form a receiving cavity together with the base plate 110. The receiving cavity is used to receive at least two layers of materials.
[0041] The first plate 120 and the second plate 130 are provided with a limiting member 140. The limiting member 140 is configured to be inserted into the receiving cavity when the first plate 120 and the second plate 130 are folded, and to be connected to at least one of the multiple sub-materials interconnected in the intermediate layer material, so as to prevent the intermediate layer material from leaving the receiving cavity.
[0042] As can be seen from the above description, the foldable packaging box of this application embodiment has a limiting member 140 on at least one of the first plate 120 and the second plate 130. When at least one of the first plate 120 and the second plate 130 is folded, the limiting member 140 is inserted into the receiving cavity and limits and prevents the middle layer material from leaving the receiving cavity. Therefore, without the need for additional accessories or materials, the material can be fixed by the integrally formed cut piece body 100. The operation is simple and convenient, and the fixing effect of multi-layer materials in the receiving cavity is effectively improved without affecting the overall appearance.
[0043] The material in this application embodiment can be the aforementioned multi-cup yogurt, such as... Figure 4 As shown, Figure 4 Each layer has two rows of yogurt cups, and each row of yogurt cups includes four yogurt cups. There are a total of 24 yogurt cups in three layers. The limiting piece 140 fixes the yogurt cups in the middle layer to prevent them from falling out of the packaging box.
[0044] Of course, in addition to multi-cup yogurt, the materials can also be layered fresh fruits and vegetables (such as apples and oranges), layered bottled skin care products, cleaning agents, bottled medicines, etc., as long as the limiting component 140 can be used to prevent one layer of material from falling out of the packaging box. This application does not make any absolute limitation on the specific category of materials.
[0045] The cut piece body 100 can be made of materials with certain bending and deformation properties, such as hard kraft paperboard, corrugated cardboard or natural bamboo fiber laminate. Of course, in some embodiments, the cut piece body 100 can also be made of solid wood, plywood or hard plastic board. When using materials that are not easily deformed and folded, such as solid wood or hard plastic board, the fold area that needs to be folded can be thinned or additional deformable connecting parts can be made, as long as it can be bent along the fold to form a packaging box.
[0046] like Figure 1 As shown, in some embodiments, along the direction away from the first plate 120, the second plate 130 includes a first side plate 131, a top plate 132 and a second side plate 133 arranged in sequence. The folded first plate 120 and the folded second side plate 133 are located on the same plane, and the first plate 120 and the second side plate 133 are joined together.
[0047] Depend on Figure 1As can be seen, the cut piece body 100 is formed by cutting a single piece of sheet material. The first panel 120, the second panel 130, and the bottom panel 110 are all outer wrapping structures of the packaging box. During the folding process to form the packaging box, the first side panel 131 and the first panel 120 are bent relative to each other. The first side panel 131 serves as one side wall of the packaging box, the top panel 132 serves as the top of the packaging box, and the second side panel 133 is connected to the first panel 120 to serve as the other side wall of the packaging box. Therefore, the cut piece body 100... Figure 1 When in its normal state, the outer surface is a continuous plane with no protrusions or snap-fit structures, making it suitable for tight stacking and easy to transport.
[0048] Furthermore, a second crease 112 is provided between the first plate 120 and the bottom plate 110, a third crease 113 is provided between the first side plate 131 and the bottom plate 110, a fourth crease 114 is provided between the top plate 132 and the first side plate 131, and a fifth crease 115 is provided between the top plate 132 and the second side plate 133.
[0049] At least one of the first crease 111, the second crease 112, the third crease 113, the fourth crease 114, and the fifth crease 115 is provided with a recessed reinforcing rib 116, which is used to engage with the material.
[0050] The first crease 111, the second crease 112, the third crease 113, the fourth crease 114, and the fifth crease 115 can all adopt crease designs in related technologies. For example, the first crease 111, the second crease 112, the third crease 113, the fourth crease 114, and the fifth crease 115 are pre-pressed creases, or the creases are easily deformable lines with spaced perforations. Pre-treatment can be performed in each crease area. In some embodiments, the crease area of the cut piece body 100 is also impregnated with a 0.1 mm polyurethane coating to enhance the stability of multiple folds.
[0051] Depend on Figure 1 It can also be seen that the first crease 111, the second crease 112, the third crease 113, the fourth crease 114 and the fifth crease 115 are arranged parallel to each other. The reinforcing rib 116 can be pre-pressed at the crease line position. The shape of the reinforcing rib 116 is approximately a groove that can be recessed towards the receiving cavity. The two sides of the reinforcing rib 116 are raised to form ribs. The direction of the ribs is perpendicular to the crease line of the corresponding crease, thereby further enhancing the bending stiffness.
[0052] When the material is a cup of yogurt, the reinforcing rib 116 can be recessed and inserted into the gap between adjacent yogurts, thereby enhancing the restraining effect on the top and bottom layers of material and preventing the top and bottom layers of material from coming out of the packaging box.
[0053] In this embodiment, the reinforcing rib 116 can refer to the structural design of the reinforcing rib 116 in the packaging box of yogurt cups in the related art. For example, in the folded state, the reinforcing rib 116 is a continuous planar part on the cut piece body 100. After folding, the external force applies pressure to the reinforcing rib 116 so that it is recessed toward the inside of the receiving cavity. The part that is recessed into the receiving cavity is used to engage with the material, thereby enhancing the limiting effect of the reinforcing rib 116 on the material.
[0054] For example, the limiting member 140 is provided at one end of the first plate 120 away from the second plate 130, and a first crease 111 is provided between the limiting member 140 and the first plate 120. The limiting member 140 is configured to bend along the first crease 111 toward the bottom plate 110.
[0055] The position of the first crease 111 is related to the height of the insertion of the limiting member 140 into the receiving cavity. That is, the closer the position of the first crease 111 is to the side of the limiting member 140, the smaller the area occupied by the limiting member 140, the smaller the height of the insertion of the limiting member 140 into the receiving cavity, and the closer it is to the material on the lower layer. The closer the position of the first crease 111 is to the side of the first plate 120, the larger the area occupied by the limiting member 140, the greater the height of the insertion of the limiting member 140 into the receiving cavity, and the closer it is to the material on the upper layer. Here, the position of the first crease 111 can be flexibly set according to the actual scenario. Generally speaking, when the limiting member 140 is inserted into the receiving cavity, it is mainly to engage with the material in the middle layer (i.e., the second layer), and there is no absolute limitation on this.
[0056] like Figure 2 As shown, as an alternative implementation, the limiting member 140 is provided on the first side plate 131, the limiting member 140 extends along the width direction of the first side plate 131, and the limiting member 140 is located on one side of the middle part of the first side plate 131.
[0057] Figure 3 In the diagram, the dashed line labeled A is the center line of the first side plate 131. The limiting member 140 and the first side plate 131 can be directly connected by adhesive. The adhesive intersection line between the limiting member 140 and the first side plate 131 is also the intersection line between the limiting member 140 and the first side plate 131. When the limiting member 140 is located on the side of the first side plate 131 near the bottom plate 110, the insertion height of the limiting member 140 into the receiving cavity is relatively small, and it is close to the material on the lower layer. When the limiting member 140 is located on the side of the first side plate 131 near the top plate 132, the insertion height of the limiting member 140 into the receiving cavity is relatively large, and it is close to the material on the upper layer.
[0058] The limiting member 140 and the first side plate 131 can be connected by vertical bonding, or the limiting member 140 and the first side plate 131 can have a certain inclined angle. When the limiting member 140 and the first side plate 131 are relatively perpendicular, the folded limiting member 140 is directly facing the material for locking. When the limiting member 140 and the first side plate 131 have a certain inclined angle, the folded limiting member 140 is set relatively inclined to the material, as long as it does not affect the locking and restraining effect of the limiting member 140 on the material.
[0059] When the intersection line of the limiting member 140 and the first side plate 131 coincides with the midpoint line of the first side plate 131, the limiting member 140 has a poor constraint effect on the material. Preferably, the midpoint line between the midpoint line of the first side plate 131 and the edge line of the first side plate 131 is used as the intersection line of the limiting member 140 and the first side plate 131. This setting can effectively enhance the clamping strength of the limiting member 140 on the material and prevent the material from slipping off one side of the packaging box.
[0060] like Figure 2 and Figure 3 As shown, the limiting member 140 in this embodiment of the application is provided with a limiting hole 141, which is used for inserting sub-materials into the limiting member 140. For example, when the material is a multi-cup yogurt, the limiting member 140 is a rectangular frame adapted to the shape of the yogurt. When the material is a cylindrical bottle of medicine, a round fruit, etc., the limiting member 140 is a correspondingly adapted circular frame, as long as it can adapt to the limiting and locking of the material.
[0061] It can also be seen that the limiting hole design allows the limiting member 140 to be directly fitted onto the material, and the limiting member 140 restricts the material in all directions, effectively enhancing the limiting and constraining effect of the limiting member 140 on the material.
[0062] As an alternative implementation, the limiting member 140 is provided with a notch that communicates with the limiting hole 141. The notch of the limiting member 140 faces the receiving cavity to be inserted into the receiving cavity. The material is limited and constrained by the insertion end of the limiting member 140. This design of the limiting member 140 can also prevent the material from leaving the packaging box, but the constraint force is slightly weaker than the limiting member 140 design that closes the limiting hole 141.
[0063] like Figure 3 As shown, in some embodiments, the number of limiting holes 141 is at least two, and the limiting holes 141 are used to match the sub-material.
[0064] The aforementioned limiting holes 141 can be two or more in number. Generally, one or two adjacent materials of the same layer can be fitted into each limiting hole 141. Therefore, setting two or more limiting holes 141 can fit different materials of the same layer in batches, thereby fixing the materials separately and effectively enhancing the constraint effect on the materials.
[0065] Of course, when the limiting member 140 is provided with only one limiting hole 141, the limiting hole 141 can completely cover all the materials in the intermediate layer, and this setting can also constrain and limit the materials.
[0066] like Figure 1 As shown, in some embodiments, at least one of the first plate 120 and the second plate 130 is provided with a cutout portion 117, which is used to expose part of the material.
[0067] The aforementioned cutout portion 117 can be a rectangular slot or a circular slot provided on the first plate 120 or the second plate 130, as long as it can expose part of the material's surface. Providing the cutout portion 117 makes it easier for consumers to observe the overall appearance of the material, such as the material's production date, brand, specifications, material list, etc. The cutout portion 117 can be provided on the side wall portion or the top plate 132 portion of the packaging box, but this application embodiment does not make an absolute limitation on this.
[0068] For example, in this application embodiment, the first plate 120 and the second plate 130 are attached by Velcro 121.
[0069] For example, both the back of the male and female sides of the Velcro 121 are adhered with adhesive. The back of the male side is directly adhered to the first plate 120 by the adhesive, and the back of the female side is adhered to the second side plate 133 of the second plate 130 by the adhesive. Figure 1 (The shaded part in the middle), the first plate 120 is folded along the second crease 112 and the second side plate 133 is folded along the fifth crease 115 and is on the same side. The sub-side and the mother side are bonded together to bond the first plate 120 and the second side plate 133.
[0070] The first plate 120 and the second plate 130 are attached by Velcro 121, which enables the cut piece body 100 to be quickly assembled into a tray. At the same time, it is also easy to disassemble the formed tray and restore it to a flat plate shape, making the switching of the foldable packaging box more convenient. The packaging box can be reused and flexibly adapted to various transportation and use scenarios.
[0071] The foldable packaging box of this application embodiment can be in the transport state. Figure 1 The diagram shows the fully unfolded flat, plate-shaped cut piece body 100.
[0072] like Figure 4 As shown, when it is necessary to assemble a package box, Figure 1The first plate 120 of the cut piece body 100 is folded along the second crease 112, the first side plate 131 is folded along the third crease 113 toward the bottom plate 110, the top plate 132 is folded along the fourth crease 114 toward the bottom plate 110, and the second side plate 133 is folded along the fifth crease 115 toward the bottom plate 110. After the lower layer of material is placed in the pre-formed packaging box, the limiting member 140 is folded along the first crease 111 toward the receiving cavity. The middle layer of material is correspondingly fitted into the limiting member 140. Then the top layer of material is stacked. Finally, the second side plate 133 and the first plate 120 are glued together with Velcro 121.
