Description

Prevent dropping packaging bag

Technical field

The utility model relates to a kind of packaging bag of connection with wrapping of piece, particularly a kind of packaging bag of packing the graininess bulk product.

Background technology

The packaging bag of existing connection with wrapping of piece generally is divided into two kinds of encapsulation type and open-types with bayonet.Get article as opening the encapsulation type packaging bag, need cut off packaging bag with scissors, or tearing notch is from the side torn packaging bag.Only need drag out bayonet socket and get final product and open packaging bag with bayonet.

The encapsulation type packaging bag is once opening, and packaging bag is just no longer sealed, and remaining article are very bad in the bag deposits, and especially granular article very easily drop out once tilting slightly.Packaging bag can not be sealed shortcoming in addition, and that is exactly that the interior article of bag are not only dry or moist easily, and very easily contaminated.Though packaging bag with bayonet does not have top said shortcoming, because the length of bayonet socket and the width constant amplitude of packaging bag, just pour out when packaging bag is sealed again behind the article trouble, need press the convex card article of bayonet socket from the beginning to the end to be combined in the spill draw-in groove.But because the length of bayonet socket is longer, it is not too convenient altogether to press, and needs carefully operation, and bayonet socket is being pressed the fashionable opening not kneaded together that is easy to occur.A lot of people no longer press behind the article and close bayonet socket owing to dislike trouble, and bayonet socket performs practically no function, and does not play the effect of packaged articles.

Summary of the invention

The purpose of this utility model is to overcome the defective that can't seal or be difficult for sealing and drop article easily after existing packaging bag is used, and provides a kind of unlatching and sealing easily, not to drop the packaging bag of article.

The technical solution of the utility model is: designed packaging bag is closed plastic packaging bag, the place, angle is provided with an oblique shear line on of packaging bag, form triangle between shear line and the angle of living in, there is a bayonet socket parallel with shear line the below of shear line.Bayonet socket is made up of built-in convex card article and spill draw-in groove.Convex card article and spill draw-in groove are integral with the both sides plastic packaging of packaging bag respectively.

The utility model manufacturing is simple, and is convenient and practical, and packaging bag both can be easy to be sheared or tear, and can not cause article to drop when depositing and pollute so that pour out and be easy to behind the article sealedly owing to be provided with bayonet socket again.

The specific embodiment

The utility model is a kind of closed plastic packaging bag 1, the place, angle is provided with an oblique shear line 2 on of packaging bag 1, form triangle between shear line 2 and the angle of living in, required angle of inclination was provided with when the gradient of shear line 2 can be poured out according to the content product, generally can and angle of living between form equicrural triangle.There is a bayonet socket 3 parallel with shear line 2 below of shear line 2.Bayonet socket 3 is made up of built-in convex card article 4 and spill draw-in groove 5.Convex card article 4 and spill draw-in groove 5 are integral with the both sides plastic packaging of packaging bag 1 respectively.The form of plastic packaging is identical with existing packaging bag with bayonet.During use, at first packaging bag 1 is cut off, exposed bayonet socket 2 from shear line 2.Again convex card article 4 is dragged out from spill draw-in groove 5, at this moment with regard to the article in the pourable bag.Though bayonet socket 2 is structurally identical with the bayonet socket in the existing packaging bag, because the length of bayonet socket 2 can be easy to press after the use lump together than the bayonet socket much shorter in the existing packaging bag.Behind convex card article 4 and spill draw-in groove 5 chuckings, article are sealed again.At this moment anyway packaging bag places, and the article in interior can not drop out.When packaging bag was made, shear line 2 also can be replaced by tear mark.

The utility model can be used for the packing of various article, especially can be used for the packing of granular pattern bulk products such as food, solid beverage, chemical industry thing, laundry soap powder.
