Abstract

The utility model discloses a plastic box for packing and transporting various foods, melon and fruit, and other articles. The utility model comprises a box body 1 and a box cover 2, wherein, the box body 1 is a hollow casing, and the upper end of the casing is provided with a flanged edge 6. The box cover 2 is a sheet plastic, wherein, the shape of which is fitted with an outline of the flanged edge 6. A plug 4 is arranged on the box body 1 or on the box cover 2, and the plug 4 is a composite unit which is composed of a frustum of a cone and a cylinder. 1-3 shrinkage grooves 5 are arranged on the plug 4, and a jack 3 is arranged on the box cover 2 or on the box body 1. When the box cover 2 is covered on the box body 1, the plug 4 is inserted in the jack 3, and the box body 1 and the box cover 2 are locked. The utility model has the advantages of material saving and convenient operation.

Description

Plastic box

The utility model relates to a kind of packing container that is used to pack, transport various food, melon and fruit and other product.In present prior art, similarly the casing and the case lid of plastic box are to band together by compress with plastic tape, hasp, perhaps bundle by craft with rope.This method is waste material both, and is very inconvenient again.

The purpose of this utility model provides a kind of saving in material, plastic box easy to use.

In order to achieve the above object, the utility model plastic box is made up of casing, case lid, and casing is a hollow housing, and upper end edge is shaped on flange with the limit, and case lid is a sheet plastic, and its shape and flange outline match.The connection of casing and case lid is to realize by plug and the jack manufactured respectively on flange and case lid periphery.The fabricate block that plug is made up of round platform and cylinder has 1-3 retraction slot on the plug, jack and plug match, and when case lid covered on casing, each plug inserted respectively in the cooresponding with it jack.

Plug can be manufactured on the flange of casing, jack is made on the case lid; Also plug can be manufactured on case lid, and jack is manufactured on the flange of casing.

Adopted technique scheme, locked mutually, so save strap, hasp and the compress of binding usefulness because casing and case lid insert jack by plug.When covering case lid, as long as plug is inserted the jack Shen, slightly firmly one to press, plug is subjected to the extruding of jack, and reduced is rebounded after passing from jack and is opened, and casing and case lid are locked together.Only slightly firmly one draw when opening case lid, the round platform at plug middle part is subjected to producing after the extruding of jack one and makes the plug reduced along round platform component radially, just deviates from from the jack Shen.So use very convenient.

Below in conjunction with drawings and Examples, this practicality newly is further described.

Fig. 1 is the constructional drawing of plastic box, adopts the full section mode; What left side demifacet reflected is that plug is manufactured on the casing flange, and jack is manufactured on case lid; What right-half plane reflected is that plug is manufactured on case lid, and jack is manufactured on the flange of casing.

Fig. 2 is the constructional drawing that has the plug of a retraction slot;

Fig. 3 is the birds-eye view of Fig. 2;

Fig. 4 and Fig. 5 are respectively the birds-eye vieies that has the plug of 3 and 2 retraction slots.

In Fig. 1, plastic box is made up of casing 1 and case lid 2.Casing 1 is a hollow housing, and its upper end edge periphery is shaped on flange 6, and case lid 2 is sheet plastics, and its shape and flange 6 outlines match.On the half of flange 6 in the left side of figure, be shaped on the plug 4 that combines as a whole with casing 1.The head of plug 4 is made up of two round platforms that lean against together, and its root is a cylinder, forms a fabricate block.On plug 4, have 1-3 retraction slot 5.On the position of case lid 2, be shaped on jack 3 corresponding to plug 4.When covering case lid 2, as long as plug 4 alignment receptacles 3 slightly firmly one are pressed, the round platform surface of plug 4 upper ends is subjected to the extruding of jack 3 at this moment, produce a convergent force radially, make the reduced of plug 4, pass to open behind the jack and reset, casing 1 and case lid 2 are pinned.When opening case lid 2, as long as case lid 2 is upwards drawn, this moment, plug 4 middle round platforms were subjected to the extruding of jack 3, and reduced is deviate from from jack 3, and case lid 2 is opened.

Shown in right one side of something of Fig. 1 is that plug 4 and case lid 2 are made one, and is shaped on jack 3 on the relevant position of casing 1, and plug 4 inserts in the jack 3, and case lid 2 and casing 1 are pinned.

Fig. 2 and shown in Figure 3 be the constructional drawing that has the plug 4 of a retraction slot 5.As can be seen from Fig. 2, the round platform of plug 4 upper ends surface is less with the angle of its axis, and the round platform surface in the middle of the plug 4 is bigger with the angle of its axis, and this is more or less freely when case lid 2 is covered, and is difficult for again simultaneously throwing off voluntarily.

Fig. 4 and Fig. 5 are respectively the constructionals drawing that has the plug 4 of 3 and 2 retraction slots 5, and the quantity of retraction slot 5 increases, and can make the amount of contraction on the plug diameter all directions more even relatively, but shortcoming is to cause technology complicated, and cost increases.
