Abstract
The utility model discloses a packaging bag which comprises an inner bag cavity, wherein the outer layer of the inner bag cavity is provided with a sealing gas interlayer, and the bag mouth of the inner bag cavity is provided with a sealing device. Compared with the prior art, the utility model has the advantages that: 1, because the sealing gas interlayer is arranged on the outer layer of the inner bag cavity, the packaging bag has excellent heat insulation and moisture prevention properties and is especially suitable for packaging a tea leaf organic fertilizer special for courtyard flowers and packaging fruits; 2, the gas interlayer can effectively prevent peculiar smells in the inner bag cavity from escaping; and 3, because the sealing device comprises a slot and a buckle which are mutually matched, and the sealing property of the sealing device is better, the sealing device can effectively prevent the peculiar smells in the inner bag cavity from escaping and can be repeatedly used.
Description
Technical field
The utility model relates to a kind of packaging bag.
Background technology
At present, comparatively simple about the packaging bag of fertilizer, be single layer structure, be difficult to protection against the tide or insulation, and single bag is damaged in transportation and practical process easily; In addition, sealing of packaging bag mostly is disposable design, in case tear, is difficult to reuse, and poor sealing performance can not prevent the effusion of peculiar smell effectively.
Summary of the invention
Utility model technical matters to be solved provides a kind of new packaging bag.
The technical scheme that its technical matters that solves the utility model adopts is: this packaging bag comprises the inner bag cavity, is provided with leak free gas interlayer at the skin of inner bag cavity, and the sack of described inner bag cavity is provided with closing device.
Further, the thickness of gas interlayer described in the utility model is 1cm.
Further, closing device described in the utility model is made up of the draw-in groove and the buckle of mutual coupling, and described draw-in groove is fixed in a side of described sack, and described snap fit is in the relative opposite side of described sack.
Further, the outer wall materials of gas interlayer described in the utility model is a snakeskin.
Further, inner bag cavity described in the utility model and gas interlayer are isolated by the high-density polyethylene plastics film.
Compared with prior art, the beneficial effects of the utility model are: (1) is owing to the skin at the inner bag cavity is provided with leak free gas interlayer, therefore have excellent heat insulation, anti-soak properties, be particularly suitable for packing special-purpose tea grounds fertilizer of garden flowers and packaging for foodstuff fruit.(2) the gas interlayer can also effectively prevent the peculiar smell effusion in the inner bag cavity.(3), can prevent effectively that the peculiar smell in the inner bag cavity from overflowing, and can be repeatedly used because closing device is made up of the draw-in groove and the buckle of mutual coupling, and sealing property is good.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the B-B cutaway view of Fig. 1;
Fig. 3 is a kind of structural representation of gas interlayer of the present utility model;
Fig. 4 is the mounting structure scheme drawing of a kind of closing device of the utility model and sack.
The specific embodiment
As shown in Figures 1 to 4, the skin of the inner bag cavity 1 of packaging bag of the present utility model is provided with leak free gas interlayer 2, and inner bag cavity 1 and gas interlayer 2 isolated by barrier film 3, in the inboard of the sack of inner bag cavity 1 along being circumferentially with closing device 6.
Be filled with other good gases of air or other heat-proof qualities in the cavity of gas interlayer 2.Thickness as gas interlayer 2 is 1cm, and then heat insulation the and moisture effect of gas interlayer 2 is better.Fig. 2 and Fig. 3 show two kinds of versions of gas interlayer 2 respectively.Wherein, as shown in Figure 2, only at the Packed gas interlayer 2 of the sidewall peripheral hardware of inner bag cavity 1; And as shown in Figure 3, being equipped with gas interlayer 2 at the sidewall of inner bag cavity 1 and the position of bottom 4, gas interlayer 2 shown in Figure 3 has better heat insulation and moisture effect.As shown in Figure 3, if the outer wall of gas interlayer 2 and barrier film 3 are only in close sack 8 places sealing-in, make the gas interlayer 2 of position of the two side of inner bag cavity 1 and bottom 4 as a whole, make whole inner bag can rout up cleaning, then be convenient to the recycling of the utility model packaging bag.
As a kind of embodiment of the present utility model, to shown in Figure 4, closing device 6 is made up of the strip-shaped clamp groove 7 and the buckle 9 of mutual coupling as Fig. 2, and the use gel is fixed in a side of sack 8 with draw-in groove 7, buckle 9 is fixed in the relative opposite side of sack 8.When buckle 9 and draw-in groove 7 mutual fastenings, be about to inner bag cavity 1 and thoroughly seal.Because the good seal performance of this closing device 6 can effectively prevent the effusion of peculiar smell, and can be repeatedly used.
The material of the outer wall 5 of gas interlayer 2 can use materials such as the compound PE of nylon, snakeskin.If use tough and tensile snakeskin, then can make the utility model packaging bag in use and transportation, avoid the phenomenon of packaging bag breakage.If barrier film 3 is the high-density polyethylene plastics film, then inner bag cavity 1 and gas interlayer 2 can be isolated well, other can not escaped to inner bag cavity 1 in the gas interlayer 2.
To sum up, the utility model packaging bag has excellent heat insulation, moisture effect and can prevent effectively that the peculiar smell in the inner bag cavity 1 from overflowing, and is particularly suitable for packing special-purpose tea grounds fertilizer of garden flowers and packaging for foodstuff fruit.
