Abstract

An airproof fast food and snack box is provided, which comprises a box cover and an open box body composed of box bottom and box wall. The lower end surface of the box cover is provided with grooves. The upper part of the box is a box mouth while the lower part is a meal container. The grooves are inspaned on edges of the box mouth. The wall inside the groove is buckled with the inner side of the box mouth by latch piece. The projection on outside wall of the groove jacks inward to the outside of the box mouth. By the interaction of both inner and outer walls of the grooves as well as both inside and outside of the box mouth, the box cover and the box body are closely buckled with each other. The box has the advantages of high pressive strength and sealability, and can effectively prevent food grease spillage. The box is also characterized by simple structure design, easy open and close and low cost, and is applicable to mass production.

Description

The sealing mess-tin

One, technical field

The utility model relates to a kind of cutlery box with the excessive device of the food and soup of preventing.

Two, background technology

Existing cutlery box such as lunch box, picnic box, mess-tin etc. generally are made of lid and box body, and food container in the box body can be carried, and conveniently has a dinner.In order to solve in the process of carrying, food and soup is excessive, the problem of leakage, sealing device also is set on the cutlery box that has, as disclosed Sealed dining box in the patents such as the patent No. 86210848,87216769,89200752,94222756, its sealing device is made of retaining mechanisms such as buckle, clinching, spiral and potted component, all not only there are shortcomings such as complex structure, cost height in these designs, and are unsuitable for the mess-tin of plastics, papery.

The patent No. 89218416 disclosed a kind of plastics plastic uptake mess-tins adopt the self-locking structure of two concavo-convex steps to replace the plane of original product to coincide, make mess-tin altogether after, not outer power can not be opened voluntarily, and has improved sealing property.This mess-tin can be out of shape when being squeezed, and makes lid and box body fastening part produce the slit, still can not prevent the excessive of soup juice effectively.

Three, summary of the invention

The purpose of this utility model is a kind of sealing mess-tin that can effectively prevent the food and soup spill and leakage of design.

The sealing mess-tin, comprise lid and by at the bottom of the box and the uncovered box body that constitutes of box wall, the lower surface of lid is shaped on groove, the top of box body is that box mouth, bottom are the storage part, described groove is linked on the box mouth edge, described trench wall and box mouth inboard by snap close piece be interlocked, the inside roof pressure box of the projection mouth outside on its outer wall.

Described snap close piece comprises the recessed button of being located at trench wall, and is located at protruding button of box mouth inboard.

The sealing mess-tin is by the interaction of the inside and outside wall of groove and box mouth medial and lateral, makes lid and closely snaps together with box body, has very high compression strength and sealing property, can effectively prevent the food and soup spill and leakage.This project organization is simple, folding with convenience, and cost is low, is suitable for a large amount of manufacturings.
