Paper boxes for sacrificial purposes

Abstract

This novel structure comprises a main unfolding component and two auxiliary unfolding components. The main unfolding component has an outer front plate perpendicular to the base plate connected to its front edge, and an inner front plate fixed to the inner surface of the outer front plate connected to its front edge. An outer back plate perpendicular to the base plate is connected to its rear edge, and an inner back plate folding to the inner surface of the outer back plate is connected to its rear edge. First fastening plates perpendicular to both sides of the inner back plate are connected to each side. The two auxiliary unfolding components are installed on both sides of the base plate and have outer side plates perpendicular to the base plate. The outer side plates are connected to first tenons that can tenon the inner front plate and the outer front plate. The outer side plates are connected to second fastening plates that can fasten the first fastening plates. The top edge of the outer side plates is connected to an inner side plate that can fold downwards to cover the first and second fastening plates. This gives the entire structure certain weight-bearing and weather-resistant properties.

Claims

1. A sacrificial paper box, comprising at least one main unfolding structure and two auxiliary unfolding structures, wherein: The main unfolding structure includes a rectangular base plate, an outer front plate connected to the front of the base plate, an inner front plate extending from the front of the outer front plate, the outer front plate being bent perpendicular to the base plate, and the inner front plate folded to the inner surface of the outer front plate and fixed to the base plate; an outer back plate connected to the rear of the base plate, an inner back plate extending from the rear of the outer back plate, the outer back plate being bent perpendicular to the base plate, and the inner back plate folded to the inner surface of the outer back plate; and first fastening plates connected to the left and right sides of the inner back plate, such that the two first fastening plates are perpendicular to the left and right sides of the base plate. The two auxiliary unfolding structures are symmetrically installed on the left and right sides of the base plate, and have an outer side plate that is relatively perpendicular to the base plate. The outer side plate is connected to a first tenon, which is bent perpendicular to the outer side plate to tenon the inner front plate and the outer front plate. The outer side plate is connected to a second fastening plate, which is folded onto the opposite inner surface of the outer side plate to fasten the first fastening plate. The top edge of the outer side plate is connected to an inner side plate, which can be folded downward to cover the first fastening plate and the second fastening plate.

2. As described in claim 1, the sacrificial cardboard box has the outer front panel connected to the front edge of the bottom plate by a first fold line; the outer back panel is connected to the rear edge of the bottom plate by a second fold line; the first buckle is connected to the left and right sides of the inner back panel by a third fold line, and the distance between the two third fold lines is controlled to be symmetrical and less than the width of the rear edge of the bottom plate; the outer side panel is connected to the first tenon by a fourth fold line; and the outer side panel is connected to the second buckle by a fifth fold line.

3. As described in claim 2, the inner back panel is provided with a second tenon at the free end of the third fold line, such that the distance between the two second tenons is symmetrical and less than the distance between the two third fold lines, and the inner side panel is provided with a third tenon that matches the second tenon, so as to fix the folded inner side panel and the inner back panel as a whole.

4. As described in claim 3, the inner side panel is connected to an intermediate panel on the other side of the third tenon by a twelfth fold line, such that the intermediate panel is folded against the inner surface of the outer side panel to fill the hollow portion located below the second snap plate.

5. The sacrificial cardboard box as described in claim 2, wherein the front edge of the inner front panel is provided with a retaining edge, and the bottom plate is provided with a retaining groove that matches the retaining edge, so that the inner front panel can be fixed to the bottom plate, and the first tenon can be securely tenoned between the inner front panel and the outer front panel.

6. As described in claim 2, the sacrificial cardboard box has wing panels on the left and right sides of the outer back panel connected by the thirteenth fold line, such that the wing panels are folded between the outer back panel and the inner back panel.

7. The sacrificial cardboard box as described in claim 2, wherein a backing plate is provided at the bottom end of the outer panel along the fourteenth fold line, such that the backing plate is bent perpendicular to the outer panel and used to abut against the bottom panel.

8. The sacrificial cardboard box as described in claim 2, wherein the outer side panel and the inner side panel are provided with grip holes.

9. As described in claim 2, the fourth fold line is parallel to the fifth fold line, so that the second buckle plate forms a fourth plate thickness compensation at the folded connection part.

10. The sacrificial cardboard box as described in any one of claims 2 to 9, wherein the main unfolding structure and the auxiliary unfolding structure are made of corrugated cardboard; the outer front panel and the inner front panel have parallel sixth and seventh fold lines at their folding joints to form a first thickness compensation therebetween; the outer back panel and the inner back panel have parallel eighth and ninth fold lines at their folding joints to form a second thickness compensation therebetween; the outer side panel and the inner side panel have parallel tenth and eleventh fold lines at their folding joints to form a third thickness compensation therebetween; the fourth fold line is parallel to the fifth fold line, so that the second snap-on panel forms a fourth thickness compensation at its folding joint.
