Embodiment 1

[0034] A kind of improved airtight packing container of the present invention, embodiment is as figure 1 As shown, it includes a box cover 1 and an open box body 2. The edge of the box cover 1 extends outwards and is provided with an annular first inner fitting groove 11 with a notch downward. The first inner fitting groove of the first inner fitting groove The lower end of the outer groove wall 113 is bent and extended outwards and upwards in turn to form an annular first outer fitting groove 12 with an upward notch; Shaped second inner fitting groove 21, the lower end of the outer groove wall 213 of the second inner fitting groove is bent and extended outwards and upwards in turn to form an annular second outer fitting groove 22 with the notch upward; The first inner fitting groove 11, the first outer fitting groove 12, the second inner fitting groove 21 and the second outer fitting groove 22 are elastic fitting grooves; the outer groove wall of the second outer fitting groo...

Embodiment 2 20

[0044] like figure 2 As shown in -24, Embodiments 2-24 are all deformations based on Embodiment 1. They all make the second inner fitting groove 21 interfere with the first inner fitting groove 11, and the second outer fitting groove 22 and the first inner fitting groove 11 have an interference fit. One outer fitting groove 12 is interference fit, between the inner groove wall of the second inner fitting groove 21 and the inner groove wall of the first inner fitting groove 11, or / and the outer groove wall of the second inner fitting groove 21 and the first inner groove wall The outer groove walls of the matching groove 11 are tangent to form an inner sealing structure along the line or / and a sealing structure along the middle line, and the groove tops of the second inner matching groove 21 and the first inner matching groove 11 are in surface contact with each other to form a surface sealing structure, The second outer fitting groove 22 and the groove bottom of the first oute...

Embodiment 25

[0047] like Figure 25 As shown, the difference between the present embodiment and the first embodiment is only that the stopper 23 is omitted, and the outer groove wall of the second outer fitting groove 22 and the outer groove wall of the first outer fitting groove 12 are matched and fitted together. anti-cone structure together. The outer groove wall 123 of the first outer matching groove is locked by the outer groove wall of the second outer matching groove 22 of the reverse cone structure, forming a second anti-tripping structure.

Abstract

The invention discloses an improved sealing packaging container. The improved sealing packaging container comprises a container cover and a container body with an opening, the side edge of the container cover is provided a first inner matching groove and a second outer matching groove which are of rotary structures, and the opening edge of the container body is correspondingly provided with a second inner matching groove and a second outer matching groove which are of rotary structures; the second inner matching groove is embedded into the first inner matching groove, and the first outer matching groove is embedded into the second outer matching groove; and an anti-releasing structure is further arranged. At least one pair of corresponding groove walls of the first inner and outer matchinggrooves and the second inner and outer matching grooves are in matched taper shapes and are attached together. The inner groove wall of the first inner matching groove and the inner groove wall of the second inner matching wall are in linear contact in an elastic abutting-against manner and / or the outer groove wall of the first inner matching groove and the outer groove wall of the second inner matching groove are in linear contact in an elastic abutting-against manner. The packaging container has the high anti-deformation capacity, the anti-releasing structure is relatively stable, and the sealing performance is better.

Description

technical field [0001] The present invention relates to containers, in particular to improved sealed packaging containers. Background technique [0002] Traditional food containers or packaging containers, such as the sealed lunch boxes disclosed in patents such as Patent Nos. 86210848, 87216769, 89200752, and 94222756, have sealing devices composed of locking mechanisms such as buckles, buckles, and screws, and sealing elements. These designs are not only There are disadvantages such as complex structure and high cost, and it is not suitable for plastic and paper fast food boxes. Patent No. 89218416 discloses a plastic blister fast food box, which uses a self-locking structure of two concave-convex steps to replace the original product's planar fit, so that after the fast food box is closed, it is impossible to open without relying on the outside, and the sealing performance is improved . But when this fast food box is subjected to extrusion deformation, lid and box body ...
