Paper lunch box with reinforced structure

This creation relates to a paper container with an improved structure, and more particularly to a paper lunch box with a reinforced structure.

Nowadays, the proportion of foreign foodies is gradually increasing. In order to save time and resources for cleaning tableware, most stores use disposable food boxes. In order to take into account the current environmental awareness, most of the disposable lunch boxes are made of decomposable paper lunch boxes. Replace the previous styrofoam lunch box.

At present, the paper lunch box is usually fixed by folding the pulp board. The side wall and the bottom of the paper lunch box are smooth outer walls. Compared with the wooden lunch box or the plastic lunch box, the meal is too large or too large. When the force is too large, it is easy to cause deformation of the paper lunch box or cause the soup to overflow. In order to strengthen the strength of the paper lunch box, most of them use a thicker cardboard to make a paper lunch box. However, the cost of this method is relatively high, which is less acceptable to the store. In addition, because the food for eating is mostly greasy, the food is directly immersed in the greasy soup or sauce when it is served in the lunch box, so that consumers can ingest excessive oil in the invisible, which may increase the health burden of the human body.

In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a paper lunch box with a reinforced structure, which can enhance the support of the paper lunch box and has the effect of draining oil.

In order to achieve the above object, the technical means adopted by the present invention is to provide a paper lunch box with a reinforced structure, comprising a bottom plate, a ring wall and an accommodating space; the bottom plate comprises a plurality of grooves, which are a ring wall surrounding the bottom plate and connected to the periphery of the bottom plate, the ring wall includes a plurality of supporting portions, which are disposed on the ring wall; the accommodating space is surrounded by the bottom plate and the ring wall form.

Preferably, the bottom plate is rectangular, polygonal, elliptical or circular.

Preferably, the ring wall further comprises a bottom edge and a top edge; the bottom edge is connected to the bottom plate; the top edge is opposite to the bottom edge.

Preferably, the plurality of support portions are formed by a vertical extension of the bottom edge of the annular wall toward the top edge.

Preferably, the plurality of support portions are parallel to the bottom plate.

Preferably, the plurality of support portions are plural or multiple ribs.

Preferably, the paper lunch box with the reinforced structure further comprises a cover portion formed by extending a portion of the top edge of the ring wall away from the bottom plate.

The paper lunch box with the reinforced structure of the creation, the plurality of grooves of the bottom plate can accommodate the greasy soup; the plurality of support portions of the ring wall can strengthen the structure of the paper lunch box, so that the paper lunch box is not easy to be The food is too large or artificially squeezed and easily deformed and twisted. In addition, the accommodating space can be closed by the cover portion to improve the convenience when carrying. Therefore, the present invention provides a paper lunch box with a reinforced structure that enhances the support of the paper lunch box and has a draining effect.

Referring to FIG. 1 , a paper lunch box 10 with a reinforced structure according to a first preferred embodiment of the present invention is formed by integrally forming a material of a pulp paperboard and pressing and pressing it, as shown in FIG. 2 . The above-mentioned one-piece forming press and folding hot press forming are conventional techniques and will not be described herein. As shown in FIG. 1 and FIG. 2, the paper lunch box 10 includes a bottom plate 11, a ring wall 12, and an accommodating space 13; the bottom plate 11 includes a plurality of grooves 111, which are attached to the bottom plate 11; The ring wall 12 surrounds the bottom plate 11 and is connected to the periphery of the bottom plate 11. The ring wall 12 includes a plurality of supporting portions 121, a bottom edge 122 and a top edge 123 opposite to the bottom edge 122. The plurality of supporting portions 121 are The bottom wall 122 is connected to the bottom plate 11; the accommodating space 13 is surrounded by the bottom plate 11 and the ring wall 12; further, please refer to FIG. 2 and FIG. As shown in FIG. 3, in the embodiment, the plurality of supporting portions 121 are formed by extending from the bottom edge 122 of the ring wall 12 to the top edge 123, and the plurality of supporting portions 121 are plural beadings. It is recessed on the ring wall 12 and faces one side of the accommodating space 13. In another preferred embodiment, the plurality of ribs 121 may be a plurality of ribs protruding from the ring wall 12 and facing one of the accommodating spaces 13 . In the first preferred embodiment, the bottom plate 11 is rectangular, but the bottom plate 11 is not limited thereto, and may be a polygonal shape, such as a pentagon or a hexagon, or an elliptical shape.

Referring to FIG. 4, the second preferred embodiment of the present invention is similar to the first preferred embodiment. The difference is that the paper lunch box 10 of the second preferred embodiment further includes a cover portion 14 It is formed by a portion of the top edge 123 of the annular wall 12 extending away from the bottom plate 11. In the specific implementation state, the accommodating space 13 of the paper lunch box 10 can be closed by the cover portion 14 to improve the convenience when carrying.

Referring to FIG. 5, the third preferred embodiment of the present invention is similar to the first preferred embodiment in that the bottom plate 11 of the paper lunch case 10 of the third preferred embodiment is circular.

Referring to FIG. 6, the fourth preferred embodiment of the present invention is similar to the first preferred embodiment, and the difference lies in the plural support of the ring wall 12 of the paper lunch box 10 of the fourth preferred embodiment. The portion 121 is parallel to the bottom plate 11.

The above description is only a preferred embodiment of the present invention, and does not impose any form limitation on the present invention. Although the present invention has been disclosed above in the preferred embodiment, it is not intended to limit the present creation, and has any technical field. A person skilled in the art can make some modifications or modifications to equivalent embodiments by using the above-disclosed technical contents without departing from the technical scope of the present invention. The technical essence of the creation Any simple modification, equivalent change and modification of the above embodiments are still within the scope of the technical solution of the present invention.
