Abstract
The utility model discloses a box cover structure of an injection molding food container, and relates to the field of injection molding food containers. The box cover structure comprises a box cover body and an annular groove formed in the edge of the box cover body, the annular groove is formed in the mode that the edge of the box cover body is upwards extended to form the inner groove wall, the upper end portion of the inner groove wall is horizontally bent outwards to form the groove top, and the outer end portion of the groove top is downwards bent to form the outer groove wall, and a horizontally inwards protruding ridge is arranged on the inner lateral face of the outer groove wall. Compared with the prior art, the box cover structure is characterized in that as a strengthening rib is arranged at the position where the groove top inside the annular groove is connected with the outer groove wall, the anti-pulling performance of the outer groove wall can be strengthened through the structure, and the box cover body is not prone to being expanded to be deformed; the structure arrangement that the lower edge of the ridge is flush with the bottom end face of the outer groove wall is adopted, so that the outer groove wall is not prone to being tore.
Description
Technical field
The utility model relates to injection moulding food containers field.
Background technology
Injection moulding food containers generally includes box body and lid, on lid, be provided with for the annular ditch groove with box body fastening, on box body, be provided with for lid on the box mouth complex edge that is interlocked of annular ditch groove, annular ditch groove is extended upward and is formed internal groove side wall 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 is extended upward and is formed inside straight edge by the box mouth of box body, 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 injection moulding food containers of this structure is in the practical application of life, common lid is at fastening repeatedly and break and open after use, the annular ditch groove meeting dilatating and deformable of lid, even the external groove sidevall of lid annular ditch groove is torn, cause lid not snap together with box body, play to prevent in box body that food overflows or foreign object is fallen into the effect in box body.
Utility model content
The purpose of this utility model is to strengthen the structural strength of lid in injection moulding food containers.
For achieving the above object, the technical scheme of the lid structure of a kind of injection moulding food containers of the utility model is:
A kind of lid structure of injection moulding food containers, comprise lid body and the annular ditch groove that is formed on lid body edge, described annular ditch groove extends upward by lid edge the upper end that forms internal groove side wall, internal groove side wall and is horizontally outward bent to form external groove sidevall downwards and forms in the outer end on bent grooving top and groove top, described external groove sidevall medial surface is provided with level to the fin of inner process, it is characterized in that: described annular ditch groove inside groove top is provided with reinforced rib with the junction of external groove sidevall.
Described reinforced rib is for to be evenly distributed polylith around annular ditch groove.
Described reinforced rib is around one week uninterrupted setting of annular ditch groove.
The lower edge of described fin flushes with the bottom face of external groove sidevall.
Adopt after technique scheme, the beneficial effect of the lid structure of a kind of injection moulding food containers of the utility model is: in annular ditch groove inside groove top and the junction of external groove sidevall, be provided with the anti-pull property that reinforced rib can be strengthened external groove sidevall, make lid after breaking repeatedly opened, the external groove sidevall of annular ditch groove is not easy to occur dilatating and deformable, and the structure setting that the lower edge of fin and the bottom face of external groove sidevall flush, so just thickeied the wall thickness of external groove sidevall, when firmly breaking and opening, external groove sidevall is difficult for being torn.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of lid in the utility model;
Fig. 2 is another cross-sectional view of the utility model lid;
Fig. 3 is the decomposition texture schematic diagram of the utility model lid and box body.
The specific embodiment
Below by the specific embodiment of setting forth by reference to the accompanying drawings the lid structure of a kind of injection moulding food containers of the utility model.
As shown in Figure 1, lid 1 of the present utility model, comprise lid body 11 and the annular ditch groove 12 that is formed on lid body 11 edges, described annular ditch groove 12 forms internal groove side wall 121 for being extended upward by lid edge, the upper end of the internal groove side wall 121 horizontally outward outer end on bent grooving top 122 and groove top 122 is bent to form external groove sidevall 123 downwards and forms, described external groove sidevall 123 medial surfaces 1231 are provided with level to the fin 124 of inner process, on annular ditch groove 12 inside groove tops 122, be provided with reinforced rib 125 with the junction of external groove sidevall 123, this reinforced rib 125 can be strengthened the anti-pull property of external groove sidevall 123, make lid 1 after breaking repeatedly opened, external groove sidevall 123 is not easy to occur dilatating and deformable, thereby realize the purpose of this utility model.
In the present embodiment, reinforced rib 125 can be arranged to be evenly distributed polylith is set around annular ditch groove 12, also can be arranged to around 12 1 weeks uninterrupted settings of annular ditch groove, and both can realize the purpose of this utility model.
For further strengthening the intensity of external groove sidevall 123, make when firmly breaking and opening, external groove sidevall 123 is difficult for being torn, in the present embodiment, structure can be further set, as shown in Figure 2 the lower edge of fin 124 1241 is flushed with the bottom face 1232 of external groove sidevall 123, be that fin 124 is arranged on external groove sidevall 123 medial surfaces 1231 bottom, so just thickeied the wall thickness of external groove sidevall 123 lower ends, thereby further realized the purpose of this utility model.
Fig. 3 is the annular ditch groove 12 of lid 1 of the present utility model and the box mouth complex edge 21 of box body 2 cross-sectional view while not fastening.
Above-described embodiment and graphic and non-limiting product form of the present invention and style, suitable variation or modification that any person of an ordinary skill in the technical field does it, all should be considered as not departing from patent category of the present invention.
