Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to a locking structure for a top and bottom box. Background Art

[0002] A top and bottom box is a packaging box in which an outer box covers an inner box from top to bottom to achieve packaging. Currently, top and bottom boxes in the market are basically sealed on the outside with plastic sealing films or plastic products such as self-adhesive stickers. If the external plastic sealing films or plastic product sealing mechanisms are removed, the top and bottom boxes will easily separate and the goods will fall out when the top and bottom boxes are picked up, thereby greatly reducing the safety and protection of the top and bottom boxes for the goods. For this reason, we propose a locking structure for top and bottom boxes. Utility Model Content

[0003] The main purpose of the utility model is to provide a locking structure for a top and bottom box. By providing a locking structure for the top and bottom boxes, the locking structure can be inserted between the top and bottom boxes so that the top and bottom boxes will not separate under the condition that the locking structure is not damaged, so that the top and bottom boxes are more tightly stuck together. To open the top and bottom boxes, it is only necessary to tear the locking structure in the middle to open the top and bottom boxes, thereby solving the problem of goods falling out and being damaged due to the lack of a locking mechanism between the top and bottom boxes, and effectively solving the problems in the background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A locking structure for a sky and ground box comprises a bottom paper sheet, a hanging paper sheet, a folded sheet, an easy-tear seam and a paper pull tab, wherein the two ends of the bottom paper sheet are vertically folded downward to form hanging paper sheets, and the bottom paper sheet between the hanging paper sheets is provided with an easy-tear seam, a paper pull tab is integrally formed outside the bottom paper sheet between the easy-tear seams, the end sheet body of the hanging paper sheet is folded outward to form an folded sheet, the hanging paper sheet and the folded sheet are vertically inserted into the engagement gap between the sky box and the ground box, and the folded sheet touches the raised skirt edge at the inner wall of the sky box.

[0006] Furthermore, the sheet body of the paper pull tab is a semicircular sheet body; the paper pull tab with a semicircular sheet body is easy to be pinched by human hands.

[0007] Furthermore, the hanging paper piece and the inverted paper piece are inserted into the wide side engaging parts of the sky box and the ground box.

[0008] Furthermore, the easy-tear seam is arranged in the middle of the bottom paper sheet.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] The utility model is provided with a locking structure for the top and bottom boxes, and the skirt edge at the inner box wall of the top box touches the reverse folded piece, so that the reverse folded piece can be buckled at the skirt edge to form a stop function when subjected to an outward pulling force, thereby ensuring the firm clamping of the top box and the bottom box. Inserting the locking structure between the top and bottom boxes can prevent the top and bottom boxes from being separated under the condition that the locking structure is not damaged, so that the top and bottom boxes are clamped together more tightly. If the top and bottom boxes are to be opened, the locking structure can be torn in the middle to open the top and bottom boxes, thereby solving the problem of goods falling out and being damaged due to the lack of a locking mechanism between the top and bottom boxes.

[0017] 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 in conjunction with specific implementation methods.

[0018] like Figure 1-4 As shown, a locking structure for a sky and earth box comprises a bottom paper sheet 1, a hanging paper sheet 2, a folded sheet 3, an easy-tear seam 4 and a paper pull tab 5, wherein the two ends of the bottom paper sheet 1 are folded vertically downward to form hanging paper sheets 2, and the bottom paper sheet 1 between the hanging paper sheets 2 is provided with an easy-tear seam 4, and the bottom paper sheet 1 between the easy-tear seams 4 is integrally formed with a paper pull tab 5, and the end sheet of the hanging paper sheet 2 is folded outward to form a folded sheet 3, and the hanging paper sheet 2 and the folded sheet 3 are vertically inserted into the box body engagement gap between the sky box 7 and the ground box 6, and the folded sheet 3 touches the raised skirt 8 at the inner box wall of the sky box 7.

[0019] The sheet body of the paper pull tab 5 is a semicircular sheet body; the semicircular sheet body of the paper pull tab 5 is easy to be pinched by human hands.

[0020] The hanging paper piece 2 and the folded piece 3 are inserted into the wide side engagement portion of the sky box 7 and the ground box 6 .

[0021] The tear-away seam 4 is arranged in the middle of the bottom paper sheet 1 .

[0022] It should be noted that the utility model is a locking structure for a sky and earth box. By providing a locking structure for a sky and earth box, when the sky box 7 and the ground box 6 need to be used with the aid of the locking structure, the bottom paper sheet 1 can be pressed against the bottom box surface of the ground box 6, and then the folded pieces 2 at both ends of the bottom paper sheet 1 can be pressed against the outer box wall of the ground box 6, and then the sky box 7 can be clamped to the ground box 6, and the folded paper sheet 2 and the reverse folded piece 3 can be inserted into the box body clamping place of the sky box 7 and the ground box 6. After the sky box 7 and the ground box 6 are fully clamped, the reverse folded piece 3 is no longer squeezed by the skirt 8 at the inner wall of the sky box 7. When the top box 7 and the bottom box 6 are opened, the paper pull tab 5 only needs to be pinched and pulled hard, so that the bottom paper sheet 1 is torn off from the easy-tear seam 4. After the bottom paper sheet 1 is broken, the two groups of sheets of the inverted sheet 3 lose the middle connection position, and the top box 7 and the bottom box 6 can be easily separated.

[0023] It should be noted that the utility model is a top and bottom box locking structure, and the components in the utility model are all components known to those skilled in the art, and the structure and principle thereof are all known to those skilled in the art through technical manuals or conventional experimental methods.

[0024] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and the description are only to illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, such as the hanging paper sheet 2 and the folded sheet 3 are inserted into the narrow edge of the sky box 7 and the ground box 6 for engagement. These changes and improvements fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
