Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0023] The fully sealed ultra-thin food container provided by the invention adopts renewable plastic materials (such as polypropylene resin) and precision mold technology, and through injection molding, is made into an ultra-thin box cover and box body with a wall thickness less than 0.5 mm. The fully sealed ultra-thin food container is formed by the cooperation of the box cover and the box body. The container is suitable for use as a snack box, food box, packaging box and the like.

[0024] Its structure refers to figure 1 As shown in Fig. 4 , including the box cover 1 and the open box body 2, the edge of the box cover 1 extends upwards to form an inner tank wall 11, and the upper end of the inner tank wall 11 is bent horizontally outwards to form a tank top 12, and the outside of the tank top 12 The end part is bent and extended downward t...

Abstract

The sealed superthin food container includes a box cover and a box body. The box cover has downward opened ring slot comprising inner slot wall, slot top and outer slot wall in the edge; and the box body has complex edge comprising inner straight edge, flat edge and outer straight edge. After the ring slot is fitted with the complex edge, one inner sealing part and one outer sealing part are formed. The slot has also protuberant blocks for locking the outer straight edge to form the separation preventing part. Therefore, the box cover may be covered to the box body to form a sealed structure with high sealing performance and high compression strength to avoid food soup leakage, and the box cover will not separate from the box body while the flexible box is extruded.

Description

technical field [0001] The invention relates to a fully sealed ultra-thin food container which can prevent food soup from leaking and has high compressive strength. Background technique [0002] Existing food containers, such as lunch boxes, picnic boxes, snack boxes, etc., are generally made of a lid and a box body, and food is contained in the box body, which can be carried around and is convenient for meals. [0003] In order to solve the problem of food soup overflowing and leaking during the carrying process, some lunch boxes are also provided with sealing devices, such as the sealed lunch boxes disclosed in patents such as Patent Nos. , buckle, screw and other locking mechanisms and sealing elements, these designs not only have the disadvantages of complex structure and high cost, but also are not suitable for plastic and paper fast food boxes. Patent No. 89218416 discloses a plastic blister fast food box, which adopts the self-locking structure of two concave-convex ...
