Description

Octagonal lunch box

This creation is related to the technical field of food packaging, especially an octagonal lunch box that can prevent the lunch box from being squeezed and deformed and dented due to heavy pressure or impact, and can stably cover the box body.

Paper lunch boxes have been widely used in the catering industry, especially in fast food. They have the advantages of convenient use and low cost. Disposable paper lunch boxes can not only be recycled into pulp, but also can be quickly degraded in the natural environment. Compared with plastic Material lunch boxes have better environmental benefits.

Since the base material of the paper lunch box is cardboard made of plant fiber as the main raw material, through folding and molding, the straight strength of the paper lunch box is worse than that of the plastic lunch box at the same cost. The two opposite corners of the paper lunch box are easily deformed when torsion is applied. Even when one end is taken, the content of the lunch box is easily deformed under the action of gravity. At present, in order to improve the upright strength of the paper lunch box, double layers are usually used. (Inside and outside) the structure of the lunch box, increase the thickness of the raw material jam, or increase the form of flanging on the surrounding wall. The first two methods undoubtedly increase the cost of the paper lunch box and weaken its market competitiveness. However, the existing paper lunch box uses a rectangular structure. The adjacent side plates on the peripheral wall are at right angles, and the corners are usually formed into an arc shape. Flanging, but limited by the expansion rate of the paper, it is very easy to crack during the flanging process. The above limits the popularization and application of paper lunch boxes.

The general lunch box is a utensil used to hold meals. The conventional lunch box mainly has a box body and an outer cover. It is a rectangular parallelepiped and has a universal paper cover design. It is impossible to clearly see the contents of the carton. It is not possible to clearly display the meal. When using the meal box, evenly spread the meal in the box body, make the outer cover cover the box body, and then bind the meal box with rubber bands; however, when making a large number of meal boxes or serving food delivery boxes, The lunch boxes containing meals often need to be stacked one after another. The bottom lunch boxes are often squeezed and deformed and dented due to the heavy weight or impact of the upper layer, causing the food and vegetable soup to leak out, destroying the appearance and deliciousness of the original food. And poor hygiene. In view of this, the creator of this work carried out in-depth research and development and improvement, which resulted in this creation.

The purpose of this creation is to provide an octagonal lunch box with high upright strength and high structural strength.

The second purpose of this creation is to provide an octagonal lunch box. Due to the octagonal structure, the four sides of the lunch box are stacked more stably, and the fitting of the transparent lid and the perfect beveled structure allow the lid to be sealed stably.

Another purpose of this creation is to provide an octagonal lunch box that can prevent the lunch box from being squeezed and deformed and dented due to heavy pressure or impact, and can stably cover the structure of the lunch box.

Another purpose of this creation is to provide an octagonal lunch box. The Japanese-style octagonal shape has long been regarded as a symbol of "good luck" or "enhancement of wealth", and it is a lucky shape that draws auspicious energy from the Shinra Vientiane. In terms of structure, the texture of meals is improved, and single and double grids are provided, so that current healthy meals or low-IG products can also be cooked in partitions.

Another purpose of this creation is to provide an octagonal lunch box. In the past, the lid of the box needs to be stabilized by rubber bands. The new box lid and the carton are designed to be embedded in the lid to eliminate the need for rubber bands. The inner side of the side of the lid A plurality of clamping strips and the side wall are mutually clamped.

The other purpose of this creation is to provide an octagonal lunch box, the lid is made of transparent plastic material, you can see the food in the lunch box, increase the beauty and promote appetite.

The octagonal lunch box that can achieve the above-mentioned new purpose includes: a box body, the box system is composed of an integrally connected enclosure and a bottom plate, the bottom plate is octagonal, and the enclosure includes eight side plates connected end to end.
