Description

Drip bag

Technical field

The present invention relates to a kind of by hook on the top of containers such as cup, dash and to get the drip bag that drips filter formula coffee easily.

Background technology

For a long time, as the coffee brewing method that can taste pure coffee like a cork, filter paper water clock mode is extensively being popularized.Adopt this filter paper water clock mode, once can extract the coffee of number person-portion (several glasss of parts) usually.

On the other hand, the people of single living increases in recent years, and owing to reasons such as nuclear familyization or birth rate reductions, the number of members of one family also reduces gradually.Therefore, the past with extract several cups of part coffees be basic filter paper water clock mode easily to be extracted one cup of part coffee be purpose, with after the disposable filter formula coffee (to call " drip bag " in the following text) that abandons replace, and go on the market in market with various product form.

Appear at the drip bag on the market so far, can be divided into two kinds substantially by the mode that is placed in cup.Wherein a kind of is that trickling filter is placed on mode (to call " putting type on the cup " in the following text) above the cup, another kind be will be contained in trickling filter the hook member lodge on the cup wall so that trickling filter hangs over the mode (to call " putting type in the cup " in the following text) in the cup.

The contrast cup is gone up putting type in putting type and the cup, go up putting type according to cup, filter paper water clock mode was identical in the past with adopting, when extracting coffee, trickling filter is not immersed in the coffee liquid of extracting in the cup, therefore, can prevent from coffee taste had in the coffee powder of dysgenic composition from trickling filter and be dissolved out.

And, the drip bag of putting type and the interior putting type of cup has various forms of products respectively on the cup, but on cup, in the drip bag of putting type, only need the plastics system drip bag that is configured as tubular substantially is placed in the upper end of cup, just finished the placement work of drip bag on cup.Adopt this cup to go up the drip bag of putting type, be placed on the cup very simple.And drip bag is made of plastics body and forms, and therefore, drip bag can deflection deformation when injecting hot water, and the opening of drip bag can not narrow down or shut when injecting hot water.Thereby it is convenient to inject hot water to drip bag.And drip bag can not be immersed in the coffee liquid of extraction, and the cleaning of drip bag is also simple after the extraction coffee.

Even the drip bag of putting type on the cup, by its kind difference, having plenty of needed to assemble in advance before being placed on the cup, wherein also have if no specification just is difficult to assemble.And in only trickling filter being placed in the drip bag that is used the cup upper end, its trickling filter that has is movable, unstable on cup.Also have, the drip bag stock size of putting type is all big on the cup, and when abandoning after purchasing in advance or using, volume is greatly a problem.

By contrast, general simple in structure than putting type on the cup of putting type in the cup, especially, by the interior bag body of putting into coffee powder, constituting by water penetration filterability encapsulant, trickling filter made of paper for this bag body lodge is formed at the hook member that pastes on the cup pair on the side of bag body, can make every effort to the saving resource of constituent material, and can low-cost production.Simultaneously, trickling filter also can be realized miniaturization.But trickling filter is immersed in the coffee liquid when extracting coffee, the filter paper water clock mode originally of therefore just being difficult to obtain dash delicious coffee.And, when clearing up trickling filter after the extraction coffee,, therefore worry the people is scalded because trickling filter is immersed in the Hot Coffee liquid.

The utility model content

As mentioned above, as drip bag, there are various cups to go up the product of putting type in putting type and the cup on the market.But, they respectively have merits and demerits, still do not have the drip bag that has both the two advantage so far, promptly have the coffee of glass last putting type delicious food, be placed on cup and inject the simplicity of hot water, the putting type drip bag that works makes at low cost in the cup and for example.

The present invention is for solving the problem of aforesaid conventional art, purpose is to provide: can obtain by filter paper water clock mode in the past dash coffee delicious food, have simple structure and be placed on the cup very easy, being placed in cup, to go up the back shape also stable, extracts and also handle easily after the coffee and the novel drip bag of safety.

Fig. 1 is the front view [Fig. 1 (a)] of the coffee droplet filter bag 10A of a kind of form of the present invention, the key diagram [Fig. 1 (b), Fig. 1 (c)] of its using method.

This coffee droplet filter bag 10A[Fig. 1 (a)], be in drip bag 1 of the present invention, to fill coffee powder, the opening of its upper end is shut, and be provided with the flanging mesh in the upper end and seal.

Hook member 3a on the outer surface of the bag body 2 that drip bag 1 is made of the encapsulant of water penetration filterability, two the relative faces that are located at bag body forms.

Bag body 2 have relative just, the back side two rectangular surfaces 2a, 2b.For example, be two with a rectangular slab one folding, be the following 2p of rectangular surfaces 2a, 2b with this crease limit, link to each other with dual-side 2q, the 2r of rectangular surfaces 2a, 2b, stay with upper end 2s and do opening, can form this bag body 2 with this.

As the encapsulant of the water penetration filterability that forms bag body 2, can use the various coffee powders that can fill ormal weight, inject the material that hot water Shi Seepage goes out coffee.For example, can use synthetic fibers such as polyester, nylon, polyethylene, polypropylene, vinylon, semisynthetic fibres such as artificial silk, by natural fibers such as Chu Shu, yellow winter daphnes separately or composite fibre fabric or the supatex fabric formed, stationeries such as the mixed copy paper that constitutes by abaca, wood pulp, polypropylene etc. etc., tea bag bag usefulness silkworm seed paper paper.Encapsulant as the water penetration filterability, from flavor, perfume, local flavor, extraction time the aspect consider, be that polyester, the second layer are the encapsulant of the three-decker formed of the supatex fabric of the mixed copy paper of standard polyester and low melting point polyester, the 3rd layer of fusion feeding method of forming for superfine polypropylene fibre making preferably by ground floor.

On the one hand, hook member 3a is made of plate-shaped materials such as paper, plastic seal materials, be located at respectively bag body 2 just, on the outer surface of the back side two rectangular surfaces 2a, 2b.In the present invention, be characterized in: this hook member 3a is by the periphery 4 that forms in its perimeter sides, at the inboard of periphery 4 and can give a hand 5 and form at the 5 inboard tongue pieces 6 that form of giving a hand from pull-up on the bag body 2 is formed, periphery 45 links to each other at 5 the up and down arbitrary end of giving a hand with giving a hand, give a hand and 5 link to each other at the other end with tongue piece 6, and one of them of periphery 4 or tongue piece 6 pasted and paid on the outer surface of bag body 2; For example, can be as shown in Figure 1, periphery 45 links to each other in 5 the upper end of giving a hand with giving a hand, and gives a hand 5 to link to each other in 5 the lower end of giving a hand with tongue piece 6, is coated with the part of netful point among give a hand 5 root and tongue piece 6[Fig. 1 (a)] paste and pay on the outer surface of bag body 2.

Fig. 2 represents the front view of this hook member 3a.As shown in the drawing, the profile of this hook member 3a is four jiaos of rectangles that are fillet.And, periphery 4 is banded in the periphery of hook member 3a, periphery 4 and give a hand and 5 separate by two sides and following first cut line (outside cut line) L1 along the rectangle hook member substantially, give a hand 5 and tongue piece 6 lean against the first cut line L1 inboard, separate along two sides of rectangle hook member and second cut line (inner incision line) L2 of top substantially.Thereby, this hook member 3a, by the first cut line L1 with periphery 4 with give a hand and separate, and, by the second cut line L2 will give a hand 5 and tongue piece 6 separate.

And then, on this hook member 3a, forming the reinforced sheet 9 that will distinguish with periphery 4 by three cuts line L3 in the periphery of periphery 4, this reinforced sheet 9 pastes to be paid on the outer surface of bag body 2.

There is not special regulation about the size of hook member 3a.But, in the occasion [with reference to Fig. 1 (c)] of aforementioned coffee droplet filter bag 10A lodge at cup 20, the stability of undersized then coffee droplet filter bag 10A reduces, the opposite excessive words then opening of the opening 8 of bag body 2 upper ends can diminish, therefore, for example, when the height H 2 of bag body 2 is 70-100mm, width W 2 during for 65-85mm, preferably the height H 3 of hook member 3a be that 35-65mm, width W 3 are 35-55mm.

And, hook member 3a pastes the position of paying at bag body 2, cross by under words, the stability of bag body 2 reduces, the opposite mistake by last words, the bottom of coffee droplet filter bag 10A lodge bag body 2 when cup 20 can be immersed in the coffee liquid of extraction, has unwanted composition and be dissolved in the coffee liquid from the coffee powder of bag body 2.Therefore, usually, hook member 3a pasted pay on bag body 2, remain on about 10-25mm between the following 3p that makes hook member 3a and the following 2p of bag body 2.

As using this coffee droplet filter bag 10A to extract the method for coffee, at first, shown in Fig. 1 (b), seal last tip cut-off with bag body 2 along the flanging mesh, open bag body 2 openings, press arrow A direction pull-up periphery 4.Secondly, shown in Fig. 1 (c), aim at the diameter of the opening 22 of cup 20, the pull-up periphery 4 again, and periphery 4 is hung on the sidewall of cup.Thus, bag body 2 relies on gives a hand 5 from two relative faces, is stretched from opposite direction in the direction of arrow B, under the state that opening 8 is opened, is hung in the central upper of cup 20.And opening shape is kept kilter by reinforced sheet 9, can prevent bag body 2 just, rectangular surfaces 2a, the 2b distortion at the back side shuts opening 8.

And, the sidewall of cup given a hand 5 and periphery 4 clamp, and, the outside of the sidewall 21 of cup by periphery 4 in arrow C direction extruding, thereby coffee droplet filter bag 10A is fixed on the top of cup 20 under the state of stabilizer pole.

At this moment, regardless of the shape and the size of cup 20, and no matter the wall thickness of cup is heavy wall or thin-walled, and coffee droplet filter bag 10A all is fixed under the stable status.

Thereby, adopt this coffee droplet filter bag 10A, can be easily coffee droplet filter bag 10A be placed on the cup 20 with the state of stabilizer pole.Be to open under the big state at opening 8 to place at this moment, also inject hot water when therefore extracting coffee easily.And this coffee droplet filter bag 10A is by the top of lodge at cup, and therefore, after the extraction coffee, drip bag is still on the coffee liquid liquid level that extracts.Thereby, may dash with the identical delicious coffee of past filter paper water clock mode, and, extract the coffee droplet filter bag 10A after the coffee, discarded also easy, do not have the danger of scald.

As described above, represented that coffee droplet filter bag 10A is behind flanging mesh sealing part opening, coffee droplet filter bag 10A is placed in example on the cup, but, the using method of coffee droplet filter bag 10A is not only for therewith among the present invention, after also can being placed on coffee droplet filter bag 10A on the cup, again coffee droplet filter bag 10A be opened mouth.

In the present invention, the form of hook member can have variform.

For example, hook member 3b shown in Figure 3 can omit the reinforced sheet 9 among the above-mentioned hook member 3a.At this moment, preferably will paste to pay and do greatly, so that bag body 2 is kept good opening shape during use coffee droplet filter bag at the tongue piece 6 of bag body 2 outer surfaces.

And, with respect to periphery 4 among the above-mentioned hook member 3a with give a hand 5 link to each other, give a hand in 5 the upper end of giving a hand 5 link to each other in 5 the lower end of giving a hand with tongue piece 6, tongue piece 6 pastes the situation of paying at the outer surface of bag body 2, also can make periphery 4 and give a hand 5 link to each other, give a hand in 5 the lower end of giving a hand 5 giving a hand with tongue piece 6 that 5 upper end links to each other, periphery 4 subsides are pair on bag body 2 outer surfaces.

For example, hook member 3c as shown in Figure 4, also can make periphery 4 form band shape at dual-side 3q, the 3r of hook member 3c and the edge of top 3s, periphery 4 and give a hand and 5 separate by first cut line (outside cut line) L1 along dual-side 3q, 3r and the top 3s of rectangle hook member 3c substantially, give a hand 5 and tongue piece 6 lean against the inboard of outside cut line L1, separate along the second inner incision line of dual-side 3q, the 3r of rectangle hook member 3c substantially.When this hook member 3c paste to pay on bag body 2 outer surfaces, periphery 4 is pasted pays on bag body 2 outer surfaces so that give a hand 5 and tongue piece 6 can pull-up.

Fig. 5 is that this hook member 3c pastes the key diagram of paying in the coffee droplet filter bag 10B of bag body 2 user mode among Fig. 4.

As shown in Figure 5, when using this coffee droplet filter bag 10B to extract coffee, at first, shown in Fig. 5 (a) arrow A, with tongue piece 6 pull-ups of the bag body 2 of opening.Then, shown in Fig. 5 (b), to the diameter of the opening 22 of cup 20, the pull-up tongue piece 6 again, and tongue piece 6 is hung on the cup sidewall 21.Thus, identical with the situation of coffee droplet filter bag 10A among Fig. 1, bag body 2 relies on gives a hand 5, is stretched towards mutually opposite direction from relative two in the direction of arrow B, under the state that opening 8 is opened, is hung the central upper at cup 20.

And, the sidewall of cup 21 given a hand 5 and tongue piece 6 clamp, simultaneously, the outside of the sidewall 21 of cup is pushed by tongue piece 6 on the direction of arrow C, therefore, coffee droplet filter bag 10B is fixed on the top of cup 20 under the state of stabilizer pole.

In addition, the employed hook member of coffee droplet filter bag of the present invention, also can be as shown in Figure 6, periphery 4 and give a hand and 5 separate by first cut line (outside cut line) L1 along dual-side 3q, 3r and the top 3s of rectangle hook member 3d substantially, give a hand 5 and tongue piece 6 leans against the inboard of outside cut line L1, second cut line (inner incision line) L2 along dual-side 3q, the 3r of rectangle hook member 3d separates substantially, periphery 4 and tongue piece 6 are separated by the 4th cut line (downside cut line) L4 along the following 3p of rectangle hook member 3d substantially.Thereby periphery 4 slightly forms banded at the whole periphery of hook member 3d.

As shown in Figure 7, be provided with the coffee droplet filter bag 10C of this hook member 3d, be placed on the cup 20.At this moment, compare with the coffee droplet filter bag 10B of Fig. 5, bag body 2 bottoms of coffee droplet filter bag 10C rely on hook member 3d to fix with being stabilized, therefore, by the considerations such as intensity of bag body 2,, more wish to use the coffee droplet filter bag 10C among Fig. 7 with the coffee droplet filter bag 10B of its use Fig. 5.

Fig. 8 is the front view of in addition different hook member 3e.On this hook member 3e, form along dual-side 3q, the 3r of hook member 3e and to separate

periphery

4 and 5 the outside cut line L1 of giving a hand, and do not form along the top 3s of hook member 3e, therefore, periphery 4 only forms band shape at dual-side 3q, the 3r of hook member 3e.Thereby, use the coffee droplet filter bag of this hook member 3e, compare with coffee droplet filter bag 10A, 10B, the 10C of Fig. 1, Fig. 5 or Fig. 7, a little less than hook member 3e supports that the function of bag body 2 is wanted.Therefore, when the intensity or the big occasion of rigidity of bag body 2, preferably use this hook member 3e.

As mentioned above, can appropriately set the form of hook member according to the formation material of bag body and hook member in the present invention.
