Abstract

The utility model relates to a sealing clamp of plastic bags, belonging to auxiliary tool for packing, which mainly solves the problems of difficult sealing of plastic freshness protection bags, comprising two clamping pieces hinge-connected together and capable of being opened and closed. The utility model is characterized in that: a rectangle groove is arranged at one clamping piece and a beam of curving flaky bulge is arranged at middle part of the groove which is of equal height with the groove; a flaky bulge is arranged at the other clamping piece which is evenly distributed centered on the antecedent bulge with the same curving direction as well as the same length and height; the utility model has the advantages that when the two clamping pieces are closed, certain clearance is retained between the lateral faces of two neighboring bulges and between the bulging end faces and the inner surfaces of two corresponding clamping grooves; locking apparatuses are correspondingly arranged at terminals of two clamping pieces. The utility model is used for freshness protection in families.

Description

A kind of plastic bag sealing folder

Affiliated technical field

The utility model relates to a kind of packing assistant product, clip that particularly can the sealed plastic bag sack.

Technical background

The food fresh keeping people of family generally adopt freezing food are put into plastic bag at present, seal with existing flat mouthful of clip, put it into refrigerator then and preserve.But flat mouthful of clip sealing is bad, when the sack of plastic bag seals when bad apt to deteriorate the or taint of odour of food.

Summary of the invention

For overcoming the shortcoming that above-mentioned prior art exists, the purpose of this utility model provides a kind of clip of the sack of sealed plastic bag reliably.

Main technical schemes of the present utility model is: this kind plastic bag sealing folder it by being hinged together and two intermediate plates can opening and closing are formed, have rectangular groove on a slice intermediate plate wherein, there is the projection of the sheet of contour with it together bending at the middle part of groove; It is the projection of contour sheet that the center is symmetrically distributed and consistent, isometric with its bending direction with aforementioned projection that twice are arranged on another sheet intermediate plate, two intermediate plates close up between the side of its adjacent protrusion of back and the end face of projection and relative intermediate plate groove inside face between leave certain interval; The end of two intermediate plates is provided with catch gear accordingly.

Described catch gear is the end at reeded intermediate plate, and two outwards outstanding latch hooks are arranged, and the lateral surface of latch hook and the angle between the lower surface are acute angle; In the end of another sheet intermediate plate outstanding, a resilient snap close are arranged, after two intermediate plates closed up, snap close rode on the latch hook.

The beneficial effects of the utility model are: the sealing curve on this kind plastic bag sealing folder can play sealing function preferably, can completely cut off effectively in the extraneous air admission plastic bag, makes the fresh-keeping effect of food better, and freshness date is longer.

Description of drawings

Be elaborated below in conjunction with accompanying drawing.

Fig. 1 is a front view of the present utility model;

Fig. 2 is the birds-eye view of Fig. 1.

Among the figure, 1-intermediate plate I, 2-intermediate plate II, 3-hinge, 4-groove, 5-projection I, 6-projection II, 7-latch hook, 8-snap close.

The specific embodiment

In Fig. 1, Fig. 2, this kind plastic bag sealing folder is hinged together by hinge (3) by intermediate plate I (1) and intermediate plate II (2), and two intermediate plates can be opened and close up.The hinge at two intermediate plate places can adopt the seccotine bonding, also can form a transition and connect thin layer when integral molded plastic.Have rectangular groove (4) on the intermediate plate I (1), there is the protruding I (5) of contour with it together corrugated sheet at the middle part of groove (4), it is the protruding II (6) of the sheet of center and symmetrical distribution with protruding I (5) that twice are arranged on the intermediate plate II (2), and the bending direction of protruding II (6) is consistent and isometric contour with protruding I (5).When two intermediate plates closed up, the twice projection II (6) on the intermediate plate II (2) dropped on groove (4) lining of intermediate plate I (1), and list in the both sides of protruding I (5).The end face and the side of projection all can be used as sealing surfaces, leave certain interval between the therefore adjacent protruding side and between the groove inside face of the end face of projection and relative intermediate plate I (1), prepare against plastic bag and here bend.

In order to improve the reliability of plastic bag sealing folder, there are two outwards outstanding, that shape is identical latch hooks (7) end in intermediate plate I (1); Have one to the outstanding resilient snap close (8) of the direction of protruding II (6) in the end of intermediate plate II (2), snap close (8) turns and bends.After two intermediate plates closed up, snap close (8) rode on the lower surface of latch hook (7).In order to prevent snap close (8) slippage, the lateral surface of latch hook (7) and the angle between the lower surface are done and are acutangulated.Catch gear can also be the rubber ring that the intermediate plate end is clamped.

During use, the vacant part of the plastic bag after the splendid attire food is suitably drawn in, again this clip is placed the above-mentioned position of sack and close up intermediate plate.Like this, plastic bag is realized sealing between three road lobes of two intermediate plates.After intermediate plate closes up, push snap close, the afterbody of its resilient arc is ridden on the latch hook.As taking out the food in the bag, break snap close into two with one's hands, open intermediate plate then and get final product.

Claims

1, a kind of plastic bag sealing folder, it is by being hinged together and two intermediate plates can opening and closing are formed, and it is characterized in that: have rectangular groove on a slice intermediate plate wherein, there is the projection of the sheet of one bending contour with it at the middle part of groove; It is the projection of contour sheet that the center is symmetrically distributed and consistent, isometric with its bending direction with aforementioned projection that twice are arranged on another sheet intermediate plate, two intermediate plates close up between the side of its adjacent protrusion of back and the end face of projection and relative intermediate plate groove inside face between leave certain interval; The end of two intermediate plates is provided with catch gear accordingly.

2, a kind of plastic bag sealing folder according to claim 1 is characterized in that: described catch gear has two outwards outstanding latch hooks in the end of reeded intermediate plate, and the lateral surface of latch hook and the angle between the lower surface are acute angle; In the end of another sheet intermediate plate outstanding, a resilient snap close are arranged, after two intermediate plates closed up, snap close rode on the latch hook.
