Description

Sealing box with good sealing effect

Technical Field

The utility model relates to a seal box, more specifically say and relate to one kind and do not have the sealing washer to have fine sealing performance's sealed effectual seal box.

Background

With the continuous development of times, people have faster and faster pace of life, and various lunch boxes are widely used in daily life. The current lunch boxes are mainly divided into sealed boxes and disposable lunch boxes made of plastic materials or paper materials, the disposable lunch boxes are generally only used for one time and are difficult to be repeatedly used, and the disposable lunch boxes are not suitable for preserving food for a long time due to poor sealing property. The sealing box is generally provided with an annular groove on the box body or the box cover, and a sealing element such as a latex ring is arranged in the groove, so that the sealing effect can be achieved when the box cover is fastened on the box body.

The sealed box with good sealing effect and guaranteed sanitary condition is often used as an appliance for taking out food, packing food in a restaurant and keeping food fresh in a refrigerator by people paying attention to life quality.

However, because the latex ring is arranged between the box cover and the cover body, bacteria are easy to breed at the position after the box cover and the cover body are used for a period of time, and people are required to disassemble and carefully clean the box cover, so that the use is troublesome.

For example, the sealed packing box disclosed in chinese patent publication No. CN103482158B, entitled "sealed packing box" is composed of a box cover and a box body with an injection molded ring. The box cover is formed by LDPE materials through an injection molding processing technology, a back-off position is designed on the inner side of the edge of the box cover, and a sealing ring made of soft rubber materials is arranged at the bending position of the inner wall of the box cover; the box body is an integrated product formed by a plastic suction process and an injection molding process, the box body part is formed by three layers or five layers of co-extruded materials through the plastic suction process, and the opening of the box body is bent outwards and is properly lengthened to form a box opening rim charge; the injection molding ring is formed on the rim charge of the box opening by a PP material through an injection molding processing technology. After the box cover is covered, the inner side of the box cover is in interference fit with the injection molding ring, the baffle ring of the injection molding ring tightly extrudes the soft rubber sealing ring in the box cover, and the inverted buckle position of the box cover buckles the bottom of the injection molding ring, so that the double-layer sealing effect is achieved. The sealed packing box adopts the soft rubber sealing ring to realize sealing, so the requirement of periodically disassembling the soft rubber sealing ring for cleaning also exists, the use is more troublesome, and the sanitation condition is easy to be worsened because the bending positions of the inner walls of the soft rubber sealing ring and the box cover are not cleaned completely.

Detailed Description

Example 1

As shown in fig. 1 to 5, the sealed box with good sealing effect in this embodiment includes a box body 1 and a sealing cover 2, an opening 101 for mounting the sealing cover 2 is formed at the top of the box body 1, four sealing and fastening sub-units are arranged at the opening 101 of the box body 1, the sealing and fastening sub-units are sub-fasteners 102 protruding outwards, and the sub-fasteners 102 are fixed on the opening 101 of the box body 1; the bottom surface of the sealing cover 2 is provided with a sealing buckling female unit 201 which can be buckled with all the subsidiary buckles 102.

The female unit 201 comprises a female buckle 2011 capable of being mutually buckled with the male buckle 102 and an inner sealing ring 2012 capable of abutting and extruding the inner side wall of the male buckle 102 and the inner side wall of the box body 1, the top end of the female buckle 2011 is fixed on the edge of the bottom surface of the sealing cover 2, the female buckle 2011 protrudes inwards, the inner sealing ring 2012 is fixed on the bottom surface of the sealing cover 2, and the outer side surface of the inner sealing ring 2012 is provided with a sealing curved surface 20121 which protrudes outwards and can abut and extrude the inner side wall of the male buckle 102 and the inner side wall of the box body 1.

The outer side surface of the sub-buckle 102 is formed by a sub-buckle surface 1021 and a sub-buckle outer inclined surface 1022 to form a triangular convex block protruding outwards.

The top of the inner side of the sub-button 102 has a sub-button inner slope 1023 for guiding the downward movement of the curved sealing surface 20121 of the inner sealing ring 2012. The inner slope 1023 of the sub-button facilitates guiding the curved sealing surface 20121 of the inner sealing ring 2012 to move downward to the bottom of the inner side wall of the sub-button 102, so that the inner sealing ring 2012 can be in close contact with the bottom of the inner side wall of the sub-button 102 for better sealing.

The inner side surface of the female buckle 2011 is formed by a female buckle bottom inner side surface 20111, a female buckle combining surface 20112 and a female buckle inner inclined surface 20113 to form a buckling groove 20114 which can be buckled with the male buckle 102.

The sub-button 102 is integrally formed with the case 1.

The female snap 2011, the inner sealing ring 2012 and the sealing cover 2 are integrally manufactured.

The cross section of the box body 1 is rectangular, the opening 101 of the box body 1 is provided with four side edges 1011, and each side edge 1011 is provided with a sub-buckle 102.

The corners between any two sides 1011 of the box body 1 are smoothly transited.
