Abstract
The utility model relates to a polypropylene package box, comprising a box body and a box cover, wherein an end of one side of the box body connected with the box cover is respectively provided with mutually interleaved embedded hinge cylindrical EPP polypropylene flanges and a cylindrical through-hole is formed in the middle of the EPP polypropylene flange and a columnar rotation axle is inserted into the cylindrical through-hole; the columnar rotation axle and the cylindrical EPP polypropylene flanges for connecting the box body with the box cover commonly form one rotation hinge structure for connecting the box body with the box cover. The package box connects and fixes the box body of the package box with the box cover by the EPP polypropylene rotation hinge structure, therefore the polypropylene package box solves the defects of the prior technology that the box body is fixed with the box cover by the metal material and has features of environmental protection and easy process. The hinge structure is manufactured in a mold together with the box body or the box cover, so as to prevent inconvenience and high cost due to the extra addition of the rotation hinge structure.
Description
Technical field
The utility model relates to a kind of packing container, especially a kind of EPP packaging polypropylene case.
Background technology
Along with the continuous expansion of EPP (polypropylene) in application, in food and fresh etc. storage and transportation, often can use packing containers such as adopting packing box that EPP makes and packing chest, many characteristics such as that such packaged form has is light, insulation, environmental protection, low cost; But present packaging polypropylene case is simple and easy relatively usually, such as the simple combination that only is a casing and case lid, perhaps adopts metallic material that casing is captiveed joint with case lid; Can in storing transportation, bring many deficiencies if casing and case lid are not fixed, such as case lid and casing since mix put or operating process such as distribution of goods in the problem that can't mate appears through regular meeting; Turn over and to face many deficiencies in the journey and metallic material is used in food product flow, such as the feature of environmental protection, manufacturing cost and manufacture difficulty; Problems such as the repairerment after the breakage.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of packaging polypropylene case, and this packing chest is connected casing easily with case lid, have manufacturing simply, characteristics cheaply.
Its technical matters to be solved can be implemented by the following technical programs.
A kind of packaging polypropylene case, comprise casing and case lid, the wherein side end that described casing and case lid join, be respectively equipped with the cylindrical EPP polypropylene of the interlaced hinge-type that is embedded surrounding edge, described EPP polypropylene surrounding edge middle part forms a cylindrical hole, is inserted with the column rotating shaft in the described cylindrical hole; The common rotary gemel structure that forms a connect box and case lid of the cylindrical EPP polypropylene surrounding edge of described column rotating shaft and difference connect box and case lid.
As the further improvement of the technical program, the cylindrical EPP polypropylene of described interlaced each that is embedded surrounding edge is an integral structure with described casing or case lid respectively.
Also as the further improvement of the technical program, described cylindrical EPP polypropylene surrounding edge can surround or the semi-surrounding structure for complete.
Also as the further improvement of the technical program, described column rotating shaft is the rotating shaft of EPP polypropylene.
As one of preferred embodiment of the present utility model, on described casing and/or case lid, preferably be provided with the groove of dodging that is used for dodging described rotary gemel structure rotation with the corresponding position of described EPP polypropylene surrounding edge.
Adopt the packaging polypropylene case of this technical scheme, be connected and fixed by the casing and the case lid of the polyacrylic rotary gemel structure of EPP packing chest, thereby solved the deficiency of utilizing metallic material static housing and case lid in the prior art, had environmental protection, easy machining characteristics.This hinge arrangement can coexist together with casing or case lid one and make in the die production and go out, and has avoided the inconvenience of extra additional this rotary gemel structure and expensive.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model being done one describes in detail.

The specific embodiment
As shown in Figure 1 to Figure 3 packaging polypropylene case its objective is a kind of adaptation of design under multiple environment, has the fixedly packing chest of the rotary gemel structure of EPP packaging polypropylene container box and case lid.
The rotary gemel structure of the utility model packing chest, be mounted on the EPP entity of two casings 1 and case lid 2 formations, in the position that two entities intersect, make the surrounding edge 11 and 21 of cylinder description of parcels, be used for forming the cylindrical cavity cell structure that holds rotating shaft, this structure countershaft has formed the encirclement structure of forms such as half bag or full bag, and is staggered into sawtooth pattern.The assembly clearance about 2mm is respectively reserved in the staggered place.Cylinder coated structure centre has the column type through hole, wherein has to slot on one side to make things convenient for the mould depanning, and like this can support large space when depanning is convenient to depanning.The middle cylinder that adopts injection moulding can rotate total as rotating shaft flexibly.Respectively making width in the bottom position of casing 1 and case lid 2 (promptly near) that two entities connect cylindrical package structure is 20mm～25mm, length equals the chamfering groove (be dodging shown in Fig. 3 groove 22) of this cylindrical package structure, the chamfering groove of this processing comes down to a groove with the function dodged, and mainly is in order to reduce the hinge arrangement stress in when rotation as much as possible.Make it can rotate bigger angle, and avoid being subjected to the squeese pressure of self rotation and rupture.
Wherein the surrounding edge 11 of casing 1 and case lid 2 and 12 formed tooth-shape structures can cross arrangements, utilize rotating shaft to peg graft and be one, also can be according to being the surrounding edge 11 of casing 1 on one side shown in Fig. 1 and Fig. 2, another side is the surrounding edge 12 of case lid 2, utilizes rotating shaft to be serially connected again.
Used this structure, accomplished the environmental protection of whole goods on the one hand, can simplify the structure of whole goods on the other hand, for example two parts of hinge arrangement add man-hour can be one-body molded with casing or case lid respectively, one time mould processes, thereby avoids it is increased cost as addition product; Simultaneously can make mould not adopt the various structures of loosing core, greatly reduce the manufacturing cost of mould and the product reject rate when making.
The utility model is casing and the case lid part that the special hinge structure that adopts the EPP polypropylene to make is connected and fixed packing chest.Can repair easily after the service failure.Casing and case lid that this structure can make EPP itself make can perfectly combine.Also do not need to use other metal species material to fix, especially satisfying food service industry must be the requirement that the environment-friendly and green material could use.
