Description

Technical Field

[0001] The utility model relates to the field of paper packaging boxes in the field of packaging technology, in particular to a combined packaging structure with buffer side guards. Background Art

[0002] In the packaging field, it is often necessary to provide side protection for packaged goods on the inside of the packaging box, especially for some goods with an offset center of gravity structure. The side protection of the packaging structure is an important link to ensure that the goods are not damaged during transportation and storage.

[0003] Generally speaking, the side protection of the packaging structure in the prior art usually uses various packaging materials and design techniques to protect the sides of the product; the commonly used treatment method is to add a cushioning lining material between the inside of the packaging box and the product, such as corner guards, soft material linings, inflatable airbags and other structures to prevent it from being squeezed, collided or damaged by vibration during handling, transportation or storage. However, this type of cushioning lining material has good applicability and low molding. However, since the cushioning lining material is independent of the packaging box and the product, it is easy to shift and fail due to external force during transportation and storage, resulting in defects in the protection of the packaging structure for the product.

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0025] See also Figure 1 , Figure 2 A preferred embodiment of a combined packaging structure with buffer side guards is provided. In this embodiment, the combined packaging structure is used to package commodity 6. The corresponding commodity 6 is a can-shaped product as shown in the figure, and a convex annular structure is formed in the middle of the can body of the product.

[0026] The combined structure of the combined packaging structure of this embodiment includes a packaging box 1, a box cover 4, and two combined lining materials padded in the packaging box 1. The packaging box 1 is a corrugated paper box with an open top surface, and a square tube structure formed of PC plastic material is formed at the four corners of the packaging box 1 as a vertical support member 2, and the vertical support member 2 is bonded to the corners of the packaging box 1 by an adhesive, and each vertical support member 2 is formed with a slot 14 on both sides against the corresponding packaging box 1 wall side.

[0027] The two combined lining materials are used in combination with the commodity 6 in the packaging box 1. The main body is a hard substrate. The main body of the hard substrate is obtained by integrally molding a hard hot-pressed cardboard or plastic board. Then, based on the position of the pre-folded edge 8, it is cut as required and divided into three independent board surfaces by the two pre-folded edges 8.

[0028] In this embodiment, the board surfaces corresponding to the first combined lining material of the two combined lining materials are the first board surface I 3, the second board surface I 11, and the third board surface I 7, while the board surfaces corresponding to the second combined lining material are the first board surface II 15, the second board surface II 12, and the second board surface II (not marked, on the opposite side of the first board surface II 15). The board heights of the first board surface I 3, the third board surface I 7, the first board surface II 15, and the second board surface II are consistent with the height dimension of the inner part of the packaging box 1, and the two sides of the board surface are respectively formed with insertion parts matching the aforementioned slots 14; while the second board surface I 11 and the second board surface II 12 are consistent with the size of the bottom surface of the packaging box 1, and have right-angle notches matching the vertical support members 2 at the four corners of the board surface.

[0029] The first side soft material lining 9 is formed on the inner side of the first panel I 3, the second side soft material lining 16 is formed on the inner side of the first panel II 15, the third side soft material lining 13 is formed on the inner side of the third panel I 7, and the fourth side soft material lining is formed on the inner side of the second panel II; in this embodiment, the contact surfaces of the first side soft material lining 9, the second side soft material lining 16, the third side soft material lining 13, and the fourth side soft material lining correspond to the outer contour shapes of the four faces corresponding to the commodity 6 on the packaging box 1 in the clockwise direction, so that the first side soft material lining 9, the second side soft material lining 16, the third side soft material lining 13, and the fourth side soft material lining can stably clamp the commodity 6 in the contact state. The surface of the second panel II 12 is a plane without other structures, while the surface of the second panel I 11 is formed with a bottom soft material lining 10 that matches the bottom surface of the commodity 6.

[0030] Linings made of different soft materials are fixed in position on corresponding board surfaces by bonding with adhesives.

[0031] When packaging, the first and second composite lining materials of the two composite lining materials are unfolded respectively and stacked in a cross shape. When stacking, the second composite lining material is at the bottom so that the bottom soft material lining 10 faces upward and is used to place the product 6. After the product 6 is stably placed on the bottom soft material lining 10, the direction is adjusted. Then, the first plate surface I 3, the third plate surface I 7, the first plate surface II 15, and the third plate surface are turned up in turn at the position of the pre-folded edge 8, and the soft material lining on the corresponding side is made to be close to the outer surface of the product 6. At this time, the composite lining material can be placed in the packaging box 1 together with the product 6. During the placing process, the four corner notches on the second plate surface I 11 and the second plate surface II 12 can use the vertical support member 2 as a guiding structure, and the product 6 on the surface of the composite lining material that maintains its position can be kept stable in the packaging box 1.

[0032] In this embodiment, the box cover 4 is a cover structure formed by overlapping honeycomb paperboard and hot-pressed paperboard and bonding them together. The lower surface of the box cover 4 has an outer contour that fits the upper surface of the product 6, and a layer of soft polyurethane foam layer 5 is formed on the outer contour surface as a fitting surface layer for the product. The above structure enables the box cover 4 to cover the top surface of the opening of the packaging box 1 after the product 6 and the combined lining material are placed, and then packaged.

[0033] In another embodiment, the box cover 4 may also use a covering structure close to the prior art, that is, the box cover may be a corrugated cardboard cover integrally formed with the packaging box body. Under this structural feature, the top surface of the product 6 requires an additional soft material lining to serve as a limiting structure to clamp and limit the top surface of the product 6. The selectable material is the same as the aforementioned soft material lining, and may be one of PU foam material, EPS foam material, EVA foam material, and EPE foam material, obtained by an integral molding method.

[0034] When taking out the product 6, one only needs to open the box cover 4, and then pull the combined lining material together with the product 6 out of the packaging box 1. In order to facilitate the placement and removal operations, in another embodiment, a lifting structure may be provided on the first panel I 3, the third panel I 7, the first panel II 15 and the upper outer edge of the third panel to assist the force operation.

[0035] In addition, in other embodiments, in order to improve the structural strength and impact resistance of the corrugated paper packaging box 1, a hard paper corner wrapping structure made of laminated cardboard can be provided at the corners of the packaging box 1 for reinforcement.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
