Summary of the invention

Main purpose of the present utility model is to provide a kind of filter bag, and it has the bag of opening, can put into the article of selecting for use, that turns in having seals characteristic, with prevent article loose from, be positioned with a pair of backguy, can make the bag after the immersion launch extruding, need not to use finger directly to push, clean hygiene more in the use, and can load voluntarily according to user's needs, and bag can constantly use, and only can use once more than known tea bag, has more the feature of environmental protection and convenience.

The technical solution of the utility model: a kind of filter bag, mainly comprise a bag, it is characterized in that: this bag has certain mesh, and has an opening that does not seal, this opening has the anti-sheet that turns over of a reflexed outward, the dual-side of bag is fixed in anti-both sides of turning over sheet, and the counter two jiaos of places of bag of turning over sheet of tool can instead plough under in the bag; And a pair of backguy, an end of each backguy is positioned the periphery place of bag, and the other end passes the backguy that becomes activity by the top margin of bag.

The utility model also can be realized by following measure: the opening of described bag faces upward or downward.

Described bag is converted into by a slice, and its both sides are the part of joint.

The both sides of described bag have a flap section.

Described bag is formed by two chip bondings, and periphery has edge sealing.

The edge sealing of described bag for sew up, bonding or hot melt pressing forms.

The both sides of described bag respectively have a flap section.

Described bag more is provided with a closing line at the Nei Fangchu of backguy.

The described backguy other end and scraps of paper join.

The scraps of paper of described two backguys can connect into same.

The backguy of described bag respectively is provided with one in the both sides of a side.

The backguy of described bag can be fixed in top margin or place, base.

The utility model is owing to be a kind of filter bag with opening, and opening has an anti-flange, and the user can load the own article of being liked, as tealeaves, coffee etc., and can utilize backguy that waste liquid is squeezed, pour out residue, be reloaded into new article, reusable.

The specific embodiment

For to the purpose of this utility model, technical characterictic and effect thereof, can have and further understand and be familiar with, lift several preferred embodiments now, and conjunction with figs. is described in detail as follows:

Shown in Fig. 3-5, a kind of filter bag, has a bag 11, bag 11 has the not opening 12 and a pair of backguy 15 of envelope, opening 12 places of bag 11 have the anti-sheet 13 that turns over of a reflexed, can insert the article 14 that will soak in bag 11 arbitrarily, these article 14 can be tealeaves, coffee or other materials etc., and bag 11 is for having certain mesh;

Instead turn over the both sides of sheet 13 and two side guys 15 of bag 11 together are positioned, one end of each backguy 15 just is positioned 17 places, interior base of bag 11, the other end is passed by the top margin 18 of bag 11, but becomes the activity backguy of a pair of pull, in article 14 are inserted bag 11 after, to instead turn over sheet 13 counter turning over, and cover the opening 12 of bag 11, after bag 11 immersion liquid, take out bag 11, utilize a pair of backguy 15, just bag 11 inner remaining liquid can be extruded (as shown in Figure 5).Wherein the movable end of backguy 15 and scraps of paper 20 join, and each scraps of paper 20 can be same a slice.

Bag 11 shown in Figure 3 is made up of two materials with mesh, its periphery is formed with edge sealing, and opening 12 can be located at place, top or place, below, opening can face upward or downward, and be provided with a longer invayination in bag 11 1 sides and divide the anti-sheet 13 that turns over that forms, the dual-side that will instead turn over sheet 13 again is positioned the dual-side of bag 11, and the action of this location can be finished simultaneously with the edge sealing action, and simultaneously the lower end of backguy 15 is located, this is the difference on the method for making, if will in bag 11, hold more article, then the both sides of bag 11 can be set as the flap section of many foldings, and its mode is to form small one and large one two block of material earlier, wherein the outer again folding of the dual-side of bulk elder generation invagination, as the structure of shopping paper bag, just has extensibility.

In addition, as shown in Figure 6, bag 11 also can to have a material of mesh made for a slice, can clearly see and have flap section 10, at this moment, another opposite side does not then have edge sealing, and flap section 10 can be located on 11 of the bags of same example with the anti-sheet 13 that turns over, be provided with two and backguy 15 is a side, just the both sides, two sides of bag 11 respectively are provided with one; Again, as shown in Figure 7, for the polarization that makes backguy 15 better, more be provided with a closing line 19 in inside, bag 11 both sides, make backguy 15 be positioned at channel-active between edge sealing line and closing line, more make to pull outward relatively and to push the action of bag 11 more smooth and easy, the situation that backguy is rocked can not take place, and the formation of edge sealing and closing line can be adopted modes such as the car side seam is closed, bonding or hot melt pressing.

In addition, as shown in Figure 8, its structure state as shown in Figure 6, but only establish a backguy 15, the inner of backguy is fixed by 30 places, upper end of bag 11, behind a circle, up passes then, so that backguy 15 is when pulling outward, bag 11 easier being tightened up.

In sum, the anti-bag that turns over sheet of the utility model utilization tool, the bag that formation can be loaded, this kind bag can use repeatedly, has had well sealing property; If will insert more article, then instead turn over length of a film, on the contrary then short, so all can keep basic closure, if when using, be not afraid of and run out of after tealeaves expands, and made by cloth as tea-bag, has higher robustness, can reuse, and use amount can control, these all be known filter bag the function that can't realize, so the utility model can provide good usability, be one fully with known different structure.

The above only is the detailed description and the accompanying drawing of the utility model preferred embodiment, be not to be used for limiting the utility model, the spirit or the embodiment and the approximate construction of its similar variation of all claims all should be covered by within the patent category that the utility model claims are defined.
