Abstract
The utility model discloses an improvement of a buckling structure of a square injection molding food container and relates to the field of injection molding food containers, in particular to the buckling structures of the injection molding food containers. The buckling structure of the square injection molding food container comprises an annular groove formed in a box cover and a box opening multi-edge formed on the box cover. The annular groove is composed of an inner groove wall, a groove top and an outer groove wall. The box opening multi-edge is composed of an inner straight edge, a flat edge and an outer straight edge. A protruding ridge horizontally protruding inwards and used for hooking the lower end portion of the outer straight edge of the box opening multi-edge is arranged on the inner side face of the outer groove wall of the annular groove. The protruding ridge is divided into multiple disconnected segments which are formed around the inner side face of the outer groove wall. Compared with the prior art, the buckling structure of the square injection molding food container is characterized in that a plurality of protruding blocks used for jacking the inner straight edge are arranged on the connecting portion of the inner side face of the inner groove wall of the annular groove and the bottom face of the groove top of the annular groove. It is guaranteed that the whole buckling structure of the square injection molding food container is firm, the structure is not prone to separation after being squeezed in any position, and therefore the purpose of the improvement of the buckling structure of the square injection molding food container is achieved.
Description
Technical field

Above-mentioned fastening structure comprises the annular ditch groove under shed being formed on lid and is formed on the box mouth complex edge on box body, annular ditch groove forms internal groove side wall for being extended upward by lid edge, the upper end of the internal groove side wall horizontally outward outer end on bent grooving top and groove top is bent to form external groove sidevall downwards and forms, box mouth complex edge forms inside straight edge for the box mouth by box body extends upward, the upper end of inside straight edge horizontally outward bends the outer end bending downwards that extends to form flat edge and flat edge and extends to form outside straight edge and form, the external groove sidevall medial surface of annular ditch groove is provided with level to the fin of inner process, when annular ditch groove cover is buckled on box mouth complex edge, this fin hook is lived the outside straight edge bottom of box mouth complex edge.
The square injection moulding food containers of said structure is when the higher food of splendid attire temperature, box body can easily be out of shape in deliquescing, when slight extruding, the box mouth complex edge of box body is easy to depart from the annular ditch groove of lid, make lid easily depart from box body, do not have and prevent that the interior food of box body from overflowing or foreign object is fallen into the effect in box body.
Utility model content
The purpose of this utility model is to provide the comparatively fastening injection moulding food containers of fastening structure of a kind of box body and lid.
For achieving the above object, the improved technical scheme of a kind of square injection moulding of the utility model food containers fastening structure is:
A kind of improvement of square injection moulding food containers fastening structure, comprise and be formed on lid to the annular ditch groove of under shed and be formed on the box mouth complex edge on box body, annular ditch groove forms internal groove side wall for being extended upward by lid edge, the upper end of the internal groove side wall horizontally outward outer end on bent grooving top and groove top is bent to form external groove sidevall downwards and forms, box mouth complex edge forms inside straight edge for the box mouth by box body extends upward, the upper end of inside straight edge horizontally outward bends the outer end bending downwards that extends to form flat edge and flat edge and extends to form outside straight edge and form, the external groove sidevall medial surface of annular ditch groove is provided with level and to inner process, for hook, lives the fin of the outside straight edge bottom of box mouth complex edge, described fin is for to form disjunct multistage around external groove sidevall medial surface, in described annular ditch groove, the medial surface of internal groove side wall and junction, bottom surface, groove top are provided with polylith for holding the projection of inside straight edge.
Described fin and projection are and are crisscross arranged, and internal groove side wall arranges two sections of interval locations that are not connected between fins of the corresponding external groove sidevall in position of projection.
Adopt after technique scheme, the improved beneficial effect of a kind of square injection moulding of the utility model food containers fastening structure is: on lid internal groove side wall, be provided with polylith for holding the projection of box body inside straight edge, when box body extrusion, there is projection to hold the inside straight edge of box body, make the box mouth complex edge of box body be not easy to depart from the annular ditch groove of lid, particularly adopt fin and projection to be the structure being crisscross arranged, can guarantee that whole fastening structure is more fastening, in any position, be squeezed not easily separated, thereby realize the purpose of this utility model.
Accompanying drawing explanation
The structural representation of fastening structure when Fig. 1 is the utility model lid and box body fastening;
Fig. 2 is the structural representation of lid in the utility model.
the specific embodiment
Below by the improved specific embodiment of setting forth by reference to the accompanying drawings a kind of square injection moulding of the utility model food containers fastening structure.
The improvement of a kind of square injection moulding of the utility model food containers fastening structure, as shown in Figure 1, square injection moulding food containers comprises lid 1 and box body 2.
Fastening structure comprises and is formed on lid 1 to the annular ditch groove 11 of under shed and is formed on the box mouth complex edge 21 on box body 2; Horizontally outward bent grooving top 112 and groove push up 112 outer end and are bent to form external groove sidevall 113 downwards and form in order to be extended upward the upper end that forms internal groove side wall 111, internal groove side wall 111 by lid 1 edge for annular ditch groove 11; Box mouth complex edge 21 forms inside straight edge 211, inside straight edge 211 upper end for the box mouth by box body 2 extends upward horizontally outward bends the outer end that extends to form flat edge 212 and flat edge 212 and bends downwards and extend to form outside straight edge 213 and form; External groove sidevall 113 medial surfaces of annular ditch groove 11 are provided with level and to inner process, for hook, live the fin 114 of outside straight edge 213 bottoms of box mouth complex edge 21, and described fin 114 is for to form disjunct multistage around external groove sidevall 113 medial surfaces.With the difference technical characterictic of immediate prior art be: the medial surface of described internal groove side wall 111 and groove push up 112 junctions, bottom surface and be provided with polylith for holding the projection 115 of inside straight edge 211.In conjunction with above-mentioned existing structure, on lid 1 internal groove side wall 111, be provided with polylith for holding the projection 115 of box body 2 inside straight edges 211, when box body 2 extrusion, there is projection 115 to hold the inside straight edge 211 of box body, make the box mouth complex edge 21 of box body 2 be not easy to depart from the annular ditch groove 11 of lid 1.
