Embodiment 1

[0042] A kind of improved airtight packing container of the present invention, embodiment is as figure 1 As shown in -4, 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 The lower end of the outer groove wall 113 of the groove is bent and extended outwards and upwards in turn to form an annular first outer matching groove 12 with the notch upward; The ring-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 fitting groove of the second outer fitting groove The...

Embodiment 2

[0050] Such as Figure 5 As shown, the difference between this embodiment and Embodiment 1 is only that: the inner groove wall of the first inner fitting groove 11 and the inner groove wall of the second inner fitting groove 21 both adopt a straight edge structure, and the inner groove wall of the first inner fitting groove 11 The inner groove wall is not in contact with the inner groove wall of the second inner fitting groove 21 .

Embodiment 3

[0052] Such as Figure 6 As shown, the difference between this embodiment and Embodiment 1 is only that: the inner groove wall of the first inner fitting groove 11 and the inner groove wall of the second inner fitting groove 21 both adopt a straight edge structure, and the inner groove wall of the first inner fitting groove 11 The inner groove wall is not in contact with the inner groove wall of the second inner fitting groove 21 , and the inner surface of the inner groove wall of the second inner fitting groove 21 is provided with a second inner pressing member 2111 . The sealing performance between the inner and outer groove walls of the first outer fitting groove 12 and the inner and outer groove walls of the second outer fitting groove 22 is enhanced by arranging the second inner pressing member 2111 .

Abstract

The invention discloses an improved sealing packaging container. The improved sealing packaging container comprises a container cover and an open container body; the edge of the container cover and the opening edge of the container body extend outwards to be provided with a first inner matching groove with a downward notch and a second inner matching groove with a downward notch, and the lower ends of the outer groove walls of the first inner matching groove and the second inner matching groove are bent and extend outwards and upwards in sequence to be provided with a first outer annular matching groove with an upward notch and a second outer annular matching groove with an upward notch; the first inner matching groove, the first outer matching groove, the second inner matching groove andthe second outer matching groove are all elastic matching grooves; the second inner matching groove is nested in the first inner matching groove, and the first outer matching groove is nested in the second outer matching groove; the improved sealing packaging container is further provided with anti-tripping structures; and at least one pair of corresponding groove walls of the first inner matchinggroove and the first outer matching groove are in a matched tapered shape and are attached together, and at least one pair of corresponding groove walls of the second inner matching groove and the second outer matching groove are in a matched tapered shape and are attached together. The packaging container has the high anti-deformation capability, the anti-tripping structures are stable, and thesealing performance is good.

Description

technical field [0001] The invention relates to a container, in particular to an improved sealed packaging container. 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 faste...
