Abstract
Description
Technical Field
[0001] The utility model relates to a lunch box, in particular to a buckled paper-plastic combination lunch box. Background Art
[0002] The combination lunch box is composed of a plastic lunch box body and an outer box. The combination lunch box has an exquisite appearance, fine workmanship and high-quality materials. It is mostly used to place Japanese bento, business meeting packages and high-end takeout.
[0003] Currently, the outer box of a combination lunch box is usually made of wood or plastic, and the outer box and the plastic lunch box body are mainly combined by gluing or placing the plastic lunch box body directly into the outer box. The combination method of gluing the outer box and the plastic lunch box body increases the transportation volume during transportation, resulting in increased transportation costs. The outer box is extremely easy to deform during transportation. In addition, glue poses certain safety risks in the food and catering industry. The combination method of placing the lunch box body directly into the outer box does not connect the outer box and the plastic lunch box body. If auxiliary methods such as tape or rubber bands are used, it will not only increase costs but also make operation more difficult. If no auxiliary methods are used, the plastic lunch box body will fall off the outer box, and the food inside the lunch box will spill. Summary of the Invention
[0004] In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a snap-on paper-plastic combination lunch box, which is easy to transport, reduces transportation costs, has a firm assembly, and is environmentally friendly and safe.
[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0006] A snap-on paper-plastic combination lunch box comprises a lid, a box body and an outer frame; the lid and box body are made of plastic, and the outer frame is made of cardboard; the outer frame can be folded and unfolded, and when unfolded, the box body is embedded in the outer frame, and the box body and the outer frame are snap-connected to protect the box body; the lid snaps onto the box body.
[0007] Furthermore, the box body is polygonal, circular or elliptical, and the box cover and the outer frame correspond to the box body.
[0008] Furthermore, the outer frame is in a sheet-like shape when folded, and in a box-like shape without a top or bottom when unfolded.
[0009] Furthermore, the outer frame is provided with a cutout to form an opening when unfolded; the box body is provided with a protrusion corresponding to the opening, the box body and the outer frame are inserted into the opening through the protrusion, and are in close contact with the periphery of the opening and are snap-connected together.
[0010] Furthermore, the incision is in the shape of an I or a W.
[0011] Furthermore, the protrusion is wedge-shaped, circular, polygonal, elliptical or fan-shaped.
[0012] Furthermore, the box body and the outer frame are rectangular, the protrusions are arranged at the four corners of the box body, and the cutouts are arranged at the four corners of the outer frame.
[0013] Furthermore, the protrusion has a length of 5 to 80 mm and a height of 1 to 20 mm.
[0014] Furthermore, the length of the incision is 5 to 80 mm, and the height is 1 to 30 mm.

[0034] like Figure 1 、 Figure 2 The figure shows a snap-on paper-plastic combination lunch box, comprising a lid 1, a box body 2, and an outer frame 3. The lid 1 and box body 2 are made of plastic, while the outer frame 3 is made of cardboard. The outer frame 3 can be folded and unfolded. When unfolded, the box body 2 fits into the outer frame 3, and the box body 2 and the outer frame 3 are snap-connected. The outer frame 3 is used to support and protect the box body 2, and the lid 1 snaps onto the box body 2.
[0035] The box body 2 is polygonal, circular or elliptical, and is rectangular in this embodiment.
[0036] like Figure 3 、 Figure 4 As shown, in this embodiment, the outer frame 3 is folded into a long rectangular sheet and unfolded into a rectangular box without a top or bottom. The four corners of the outer frame 3 are provided with cutouts 5. The cutouts 5 can be in the shape of an I-beam or a Chinese character, with an I-beam shape being preferred in this embodiment. The cutouts 5 range in length from 5 to 80 mm and in height from 1 to 30 mm. In this embodiment, the cutouts 5 are preferably 40 mm in length and 8 mm in height.
[0037] like Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 As shown, the top of the box body 2 is provided with a downwardly turned outer edge 6 to form a groove. When assembled, the top of the outer frame 3 is placed in the groove, and the box body 2 is embedded in the outer frame 3.
[0038] The box body 2 is provided with protrusions 4 at the four corners, forming a snap fit. Protrusions 4 can be wedge-shaped, circular, polygonal, elliptical, or fan-shaped, and in this embodiment, are trapezoidal. Protrusions 4 range in length from 5 to 80 mm and in height from 1 to 20 mm. In this embodiment, a length of 12 mm and a height of 6 mm are preferred.
[0039] The cutout 5 of the outer frame 3 forms an opening when unfolded, and the box body 2 is placed in the outer frame 3. The protrusions 4 at the four corners of the box body 2 are inserted into the opening, and the protrusions 4 are in close contact with the periphery of the opening, thereby tightly and firmly snapping the outer frame 3 and the box body 2 together.
[0040] The outer frame 3 of the present invention is foldable, and the paper outer frame 3 and the plastic box body 2 can be transported separately, which greatly reduces the original transportation volume. This not only improves transportation efficiency, reduces damage, but also reduces overall costs. The box body 2 and the outer frame 3 are connected by snap fasteners without the use of glue or tape, which is easy to operate and the outer frame 3 does not easily fall off after being connected to the box body 2.
[0041] The utility model is provided with an outer frame 3, which can be stably stacked in multiple layers when delivering and packing meals, and the box body 2 is not easy to collapse.
[0042] The outer frame 3 of the present invention is made of cardboard, which reduces the use of plastic and is environmentally friendly and safe. Moreover, the paper outer frame 3 can be printed with various patterns, which is more beautiful than the existing wooden and plastic outer boxes.
[0043] The utility model improves the outer box into an outer frame 3, which has a simple structure and a simple manufacturing process, and greatly reduces the production cost.
[0044] The box body 2 and the outer frame 3 of the utility model are inserted into the opening through the protrusion 4, and the protrusion 4 is in close contact with the periphery of the opening and is connected together by a snap. The snap connection is tight, stable, and not easy to fall off.
[0045] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and concepts of the present invention shall be covered by the scope of protection of the present invention.
