Embodiment 1

[0035] A new type of sealed packaging container of the present invention, as shown in Figure 1-2, comprises a box cover 1 and an open box body.

[0037] The mouth of the box body 2 is bent upward and extends to form the inner groove wall 211 of the second inner matching groove 21. The second inner groove wall 211 is formed.

[0039] The limiting protrusions 23 are distributed on the inner side of the outer groove wall 223 of the second outer matching groove along the circumferential direction, so

[0041] The novel sealed packaging container of the present invention, through the taper matching of the first inner matching groove 11 and the second inner matching groove 21,

[0042] The upper end of the outer groove wall 123 of the first outer matching groove is inclined upwardly and outwardly to be tensioned and held against the outer surface of the second outer matching groove.

[0043] The outer groove wall 223 of the second outer matching groove extends downward from the upper end ...

Embodiment 2 8

[0047] As shown in Figures 3-9, Embodiments 2-8 are the deformation structures of Embodiment 1, specifically, the second inner matching groove is

Embodiment 9

[0050] As shown in FIG. 10 , the difference between this embodiment and the first embodiment is only that the limit bump 23 is omitted, and the second outer matching groove

Abstract

The invention discloses a new type of sealed packaging container, which comprises a container cover and an open container body. The edge of the container cover is provided with a first inner fitting groove and a first outer fitting groove of a rotary structure, and the mouth edge of the container body is correspondingly provided with The second inner fitting groove and the second outer fitting groove of the rotary structure; the second inner fitting groove is nested in the first inner fitting groove, and the first outer fitting groove is nested in the second outer fitting groove; there is also an anti-loosening buckle structure. At least one pair of corresponding groove walls of the first inner fitting groove and the second inner fitting groove are in a suitable cone shape and fit together. The outer groove wall of the first outer fitting groove and the outer groove wall of the second outer fitting groove are in line contact with each other in an elastic supporting manner. The outer groove wall of the second outer fitting groove extends downwards from the upper end and is provided with two indentations that are easy to tear. The wall thickness of the outer groove wall of the second outer fitting groove. The invention has strong anti-deformation ability, relatively stable anti-tripping structure and good sealing performance.

Description

New sealed packaging container technical field [0001] The present invention relates to containers, in particular to a novel sealed packaging container. Background technique [0002] Traditional food containers or packaging containers, such as patent numbers 86210848, 87216769, 89200752, 94222756 The sealed lunch box disclosed in such patents, the sealing device is composed of locking mechanisms such as snaps, snaps, screws, etc., and sealing elements. The 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 and convex steps to replace the plane of the original product The fit makes it impossible to open the fast food box without relying on the outside after the fast food box is closed, and the sealing performance is improved. But this fast food box When being sque...
