Description

Box frame structure

Technical field:

The utility model relates to a frame structure of a box body, in particular to a box body that can be easily packaged and removed by the setting of a joint unit so that the food contained in the box body can be effectively sealed and easily taken. effect.

Background technique:

Generally existing paper-made container 6 is placed, and as shown in Figure 8, this container 6 can be the container 6 that can hold food such as supporting plate, bowl, cup dinner plate or lunch box, and this container 6 is with lunch box now. For example, it has an accommodating portion 61, and the opening end of the accommodating portion 61 has an arc-shaped peripheral edge 62, the required food can be placed in the accommodating portion 61, and is correspondingly closed by a plastic film 63 The arc-shaped peripheral edge 62 of the container 6 is used for holding and preserving food.

Although the container 6 can be used to hold food, because the container 6 is only provided with a plastic film 63 on the arc-shaped periphery 62 of the opening of the container 6 after holding the food, to achieve the effect of closing the opening of the container 6 . Therefore, when the plastic film 63 is closed on the arc-shaped peripheral edge 62, the arc-shaped peripheral edge 62, which is made of paper with the container 6, is often deformed due to the inadvertent extrusion of the container 6 when storing or taking it. phenomenon, and cause the plastic film 63 to be closed on the arc-shaped peripheral edge 62, resulting in the situation that the two cannot be flattened, resulting in insufficient sealing, and resulting in a gap that makes the food, soup or fruit juice in the container 6 in transit or taken. Seep out from this slit when taking, or make outside air enter container 6 by this slit when displaying, affect the preservation quality of the food in the container, and lose the meaning of sealing plastic film 63; The arc-shaped peripheral edge 62, therefore, when the arc-shaped peripheral edge 62 is bonded to the plastic film 63, the two are only combined in a point contact manner, so that the plastic film 63 cannot be firmly attached to the arc-shaped peripheral edge 62 with a larger area , and then cause insufficient sealing, resulting in the phenomenon that the arc-shaped peripheral edge 62 and the plastic film 63 are easy to separate; therefore, the general existing container 6 is not suitable for actual use.

Utility model content:

The technical problem to be solved by the utility model is to provide a frame frame structure for the box body in view of the above-mentioned deficiencies in the prior art. The setting of the joint unit can be used to make the adhesive film of the closed box body easy to seal and tear off, so that the box body The food in the container achieves effective sealing and easy access.

In order to solve the above technical problems, the technical solution adopted by the utility model is: a box body frame structure, the box body is composed of at least one inner layer and an outer coating layer, and the box body is provided with at least one accommodation area; It is characterized in that: the end edge of the accommodating area of the box body is combined with a joint unit, and the joint unit has at least one socket portion joined to the peripheral edge of one side of the accommodating area, and an extension plate transversely arranged at one end of the socket portion , and a bent plate extending downward from one end of the extension plate.

In this way, the arrangement of the joint unit can make the adhesive film closing the box body easy to seal and tear off, so that the food contained in the box body can be effectively sealed and easy to take.

Detailed ways:

Please refer to Fig. 1-Fig. 3, which is the first embodiment of the present utility model, which is a box body frame structure, which is at least composed of a box body 1 and a joint unit 2; The setting makes the adhesive film closing the box body 1 easy to seal and tear off, so that the food contained in the box body 1 can achieve effective sealing and easy access.

The above-mentioned box body 1 is at least composed of an inner layer 11 and an outer coating layer 12, wherein the inner layer 11 is made of biodegradable raw materials, or can be selected from polylactic acid (PLA), polyethylene lactone ( PCL), aliphatic, PHA microbial fermentation and other biodegradable raw materials and their mixtures, and the outer coating 12 can be selected from polyethylene (PE) or polypropylene (PE) material, and the box body 1 is provided with at least one accommodating area 13.

The joint unit 2 is combined with the end edge of the accommodation area 13 of the above-mentioned box body 1, and the joint unit 2 has at least one sleeve portion 21 that is engaged with the periphery of one side of the accommodation area 13, and a sleeve portion 21 that is arranged transversely An extension plate 22 at one end, and a bent plate 23 extending downward from one end of the extension plate 22, wherein the side of the joint unit 2 corresponding to the accommodating area 13 is made of biodegradable raw materials, or can be selected from polylactic acid (PLA ), polyglycolide (PCL), aliphatic, PHA microbial fermentation and other biodegradable raw materials and their mixtures, and the other side of the joint unit 2 can be selected from polyethylene (PE) or polypropylene (PE) material. If so, a brand-new frame frame structure of the box body is formed by the above structure.

During use, the box body 1 can be made into a rectangular box body or a circular box body as required, such as a container for holding food such as a plate, a bowl, a cup, a dinner plate or a lunch box. Take the lunch box container as an example. When in use, food 3 such as liquid, raw food or cooked food can be placed in the accommodation area 13 of the box body 1, and then sealed on the joint unit 2 with a sealing machine (not shown). There is an adhesive film 4 sealed on the surface of the box body, and the adhesive film 4 is bonded to the planar extension plate 22 set on the joint unit 2, so that the adhesive film 4 of the closed box body 1 can be easily packaged by using the setting of the joint unit 2 And tear off, so that the food 3 contained in the box body 1 can achieve effective sealing and easy access.
