Description

Multi-grid lunch box

Technical Field

The utility model relates to a disposable cutlery box field especially relates to a many check cutlery box.

Background

The lunch box made of polystyrene and plastic materials which are used in large quantities in the past is not rotten after being discarded, generates harmful gas after being burnt, and causes serious pollution to human living environment. Therefore, many developed and developing countries have banners to use lunch boxes made of such materials, and for this reason, the industry uses paper lunch boxes meeting environmental requirements instead of lunch boxes made of polystyrene and plastic materials. The paper meal box is a single basin type structure, and is developed into a separate paper meal box with separate dishes.

Common multi-grid lunch boxes have various shapes, such as chinese patent application No.: 99214424.8 discloses a multi-grid lunch box, which comprises a main box body and at least two sub-box bodies; the main box body comprises a bottom plate, the periphery of the bottom plate is respectively extended to form side plates which can be bent upwards to form a containing part, one end of the side plate at the rear part of the main box body is extended to form an adhesive plate which protrudes out of the containing part and can be used for adhering the auxiliary box body, a cover plate with the same width is integrally extended from the top edge of the rear side plate and the top edge of the adhesive plate, and the width of the cover plate is equal to the width of the main box body and the auxiliary box body after adhesion; the auxiliary box body comprises a bottom plate, side plates capable of bending upwards are integrally formed at the periphery of the bottom plate respectively, a reinforcing plate is integrally connected to the outer edge of the side plate of the auxiliary box body corresponding to the main box body, and the reinforcing plate can be bent and adhered to the inner side surface of the side plate of the main box body. Because the folded parts of the separating sheets of the main box body and the auxiliary box body are arranged at the edges of the corresponding paper materials, the drawing rod of the mould is correspondingly arranged at the edges, thus simplifying the manufacturing difficulty of the drawing rod, reducing the defective products in the bending and drawing process and greatly reducing the manufacturing cost of the lunch box; however, when the lunch box is formed, a drawing rod is usually required to be designed at a corresponding position in a mold, so that when the lunch box is pressed by the mold, the folding part can be drawn and bent into the box body, the design of the mold is complicated, and the conventional production forming equipment for multi-grid lunch boxes allows eight fixed points (points where creases intersect) at most, so that the combination of the auxiliary boxes is difficult without the need of the auxiliary boxes when the main box occupies 8 fixed points.

To this end, referring to fig. 1, the applicant has created a multi-cell paper lunch box, which comprises a box cover 10 and a box body 20, wherein the box cover 10 and the box body 20 are folded by a piece of formed paper, and a rib 30 is arranged in the box body 20, the rib 30 comprises a transverse rib 31 and a longitudinal rib 32, the transverse rib 31 and the longitudinal rib 32 are crossed and fixed into a whole and are buckled in the box body 20, so as to divide the space in the box body 20 into a plurality of storage tanks for containing different kinds of food; however, the rib 30 is not connected with the bottom surface of the box body 20, and when food with soup in a single storage tank is contained, the problem of leakage is easily caused; therefore, after further improvement of the applicant, referring to fig. 2 and 3, by forming the elongated grooves 1 on the bottom surface of the box body 21 at positions corresponding to the transverse ribs 31 and the longitudinal ribs 32, and by extending through the vertical grooves 2 at the positions of the side walls 21 of the box body 20 where the transverse ribs 31 and the longitudinal ribs 32 are in contact with each other, and by forming the vertical grooves 2 at the positions of the longitudinal ribs 32 where the transverse ribs 31 and the longitudinal ribs 32 are in contact with the transverse ribs 31, the transverse ribs 31 and the longitudinal ribs 32 are covered at the elongated grooves 1 and the vertical grooves 2, the fixing pieces 3 are formed at the two sides of the rib 30 corresponding to the elongated grooves 1, the connecting pieces 4 are formed at the positions of the vertical grooves 2, and the rib 30 is fixed by adhering and fixing the fixing pieces 3 and the connecting pieces 4 to the bottom surface and the side walls 21 of the box body 20, respectively, so as to fix the rib 30 and prevent the; however, because the connection piece effect that sets up on the check makes the height dimension of check be less than the height dimension of box body lateral wall usually, and the lid has certain appearance chamber, make to have great interval between lid roof and the check, when holding more meal in the many check cavities that the cutlery box was flourished, rocking that produces in transporting makes during the soup overflows other check cavities, and because the cutlery box is the paper cutlery box, stack in a plurality of cutlery boxes, the lid is pressed easily and is subsided, it is poor to cause the lid of box body and lid to close the nature, cause the leakage.
