Abstract
An infusion package comprising two panels of porous material sealed together at their peripheral margin to form an infusion containing compartment. Two further regions of the panels spaced inwardly from their peripheral margin are also sealed together. A drawstring enters and exits the compartment and is looped within the compartment around the sealed regions. The ends of the drawstring outside the infusion package may be provided with tags. In use, pulling the ends of the drawstring in opposed directions causes the package at least partially to collapse, thus expressing residual liquid therefrom.
Description
The present invention relates to a kind of impregnating bag, for example be inclusive with the tea bag that can in liquid, produce extract or coffee bag etc.
Tea bag is the sealing porous bag that includes tealeaves, and it can place cup or the teapot that fills boiling water, so that infusion tea.Usually, particularly when impregnating bag places cup or mug, before having tea, take out tea bag.But still contain liquid when taking out tea bag, so liquid can drip and on left any surface below tea bag.Because tea (but and other extract) has strong contamination characteristic, thereby is undesirable situation.So after normally tea bag being taken out, for example adopt teaspoon that remaining liq is squeezed out from tea bag so that the tea bag relatively dry some.But this method of taking out remaining liq from tea bag is not effective especially.As guaranteeing when taking out liquid that liquid is all stayed in cup or the mug is very difficult, and adopts teaspoon or other hand held appliances that obtains easily often easily maybe can not accomplish.
The suggestion certain methods is used for addressing the above problem, and a kind of method easily that effectively reaches of extruding raffinate from the impregnating bag such as tea bag for example is provided.Great majority in these existing methods are to adopt some mechanisms, and it applies external force to impregnating bag, so that extrude raffinate.Therefore for example in WO/13580, be fixed with a rope that passes impregnating bag, after using impregnating bag, can spur rope it is compressed, and the rope of depressing impregnating bag simultaneously passes side, so that be crowded together with its opposite side in impregnating bag one side.Have a mill bristol on the rope, in order to the extrusion impregnating bag.
There are some shortcomings in said mechanism: at first, if there is not card, must adopt some other instrument to come the extrusion impregnating bag, user's finger for example, clearly, like this unlike coming teaspoon or other apparatus the extrusion impregnating bag more convenient with one simply, if itself has card, card also is easy to the liquid immersion that is extruded and the drop that drips, thereby can not reach desired effect.Again it, squeezing action occurs over just on the corresponding point of bag edge, thus can not be very effective, and can not extrude all raffinates in the impregnating bag.
In a kind of alternative of said method, also be to use one at the rope that when pulled sack is compressed, this rope places the impregnating bag periphery in the form of a ring, has therefore surrounded whole sack, makes the sack compression when pulling.The example of this kind structure is disclosed among the US-A-3415656.In the document, becket bridle is sealed in the raceway groove in the periphery of impregnating bag, so can move freely in raceway groove.The opposite end of becket bridle can be drawn back, so that seal this ring and compression sack.In this scheme, the status requirement becket bridle of becket bridle in the impregnating bag periphery must accurately be located in periphery, and requires carefully the edge to be sealed, so that form raceway groove.Like this, produce under the situation of impregnating bag on high-speed automation ground, the situation of a large amount of wastes of unlikely appearance is very difficult owing to produce off-grade, so the impregnating bag described in the US-A-3415656 is not particularly suitable for business-like generation.
The further scheme of attempting to address the above problem is to propose in WO 92/6203.In this document, a pair of hauling rope extends into impregnating bag inside, is passed in the sealing member between the sheet material at the primary importance place on the sack periphery, and extends and cross sack inside, arrives on the sack periphery roughly on the fastening point at relative position place.Every hauling rope is held between two hermetic units that are fastened on sheet material.Be compressed oppositely just the bag wall being moved together, thereby made to impregnating bag during pulling traction rope haply, and therefrom extrude remaining liq.
An object of the present invention is to provide a kind of in WO 92/6903 improvement project of the impregnating bag of disclosed general category shape.
According to a scheme of the present invention, the impregnating bag that is provided comprises the sheet material of two aerated materialss, and aerated materials is sealed together around the periphery of bag, to limit a macerate cell.Sheet material is also sealed at least one zone, and this zone and periphery are inwardly spaced apart.A hauling rope advances and goes out the macerate cell of impregnating bag through periphery, and in cell, form ring-type around the sheet material seal area, adopt this method, when reversing sense dragline messenger one end, make that impregnating bag is produce to shrink in the part at least, thus liquid by extruding in the bag.
In the present invention, hauling rope is pulled in the bag wall together as prior art, so that the compression impregnating bag is extruded residual liquid.As in WO 92/6903, the tea cell that contains that hauling rope passes through to the small part impregnating bag extends internally.But hauling rope is not fixed on sealing the margin, but the centre portion of hauling rope in containing the tea cell loosely in the form of a ring, it is around from inside at interval the seal area of sheet material of the seal perimeter of bag.Adopt this mode, as can be seen, the possibility of tearing bag when removing liquid can reduce.Have, the sealing member between the sheet material of seal area can remain on hauling rope in the macerate cell again, so that the situation of squeezing effect when being better than being sealed in rope on the sheet material, like this, hauling rope setting of the present invention can be given some improvement to the squeezing action of impregnating bag.
In addition, setting of the present invention is owing to exempted the essentiality that the centre portion of hauling rope is fixed on the edge when sealing, really the advantage that has manufacture view is in order just to need to adopt the tolerance on fit of precision, and may damage sealing to this fixing in hauling rope location.
Two or more alternate discrete seal areas are preferably arranged between sheet material.Hauling rope can be around two in these seal areas in the form of a ring.When the end of dragline messenger, this set can more effectively be compressed impregnating bag.
A seal area or a plurality of seal area preferably are discrete little island.These islands preferably have fillet, but their global shape can be arbitrarily.
In an example, hauling rope is a single rope, and it advances and go out the macerate cell with the position that separates on periphery, and hauling rope is walked around two seal areas extensions at impregnating bag diagonal angle.Utilize this device, on roughly opposite direction, during the end of dragline messenger, bag is compressed on two dimensions, thereby liquid therefrom is extruded effectively.
A kind of structure of replacement is to have set up four seal areas in bag, each seal area is positioned at each angle near the macerate cell of periphery, hauling rope passes between each seal area and periphery, and rope itself intersects before stretching out sack, so that form the becket bridle around the edge of macerate cell.
Be positioned at impregnating bag hauling rope end in addition, be preferably with a tongue bars.This can make hauling rope be easy to grip.Each end of rope can be posted tongue bars respectively, also independent tongue bars can be set, and can tear in two, so that pulling traction rope when needed.Can adopt size and the similar tongue bars of impregnating bag.At this moment, tongue bars can rely on the sack doubling simply, so that stack vanning, also can and wait after using when throwing aside, as the support of impregnating bag.If adopt the single tongue bars of the hauling rope with two ends, then tongue bars can be bored a hole or partial cut along center line, therefore can tear more easily.
Be sealed in the advancing with exit of hauling rope of sheet material on periphery preferably interrupts, and this is to damage sealing in order to avoid because of the existence of hauling rope, and makes hauling rope can more easily pass the edge in use, thereby alleviates any danger that damages sack.
Hauling rope and the seal area layout in the dipping cell preferably is symmetrical in the symmetrical plane by the impregnating bag center.Can more effectively from impregnating bag, push liquid like this.
Impregnating bag of the present invention can have shape and size arbitrarily.Can imagine, but the present invention will have maximum purposes in the relevant application facet for preparing the macerate of beverage.It is specially adapted to tea bag and the coffee bag that infusion is used, generally rectangular, the square or circular of this impregnating bag.
Several optimum examples of the present invention is only described with reference to the accompanying drawings as an example and in addition, and all identical feature will be annotated label with roughly the same in the accompanying drawings, wherein:
Fig. 1 is first embodiment of impregnating bag of the present invention;
Fig. 2 is the modification of impregnating bag shown in Figure 1;
Fig. 3 is second embodiment of impregnating bag of the present invention;
Fig. 4 is the 3rd embodiment of impregnating bag of the present invention.
In Fig. 1, generally indicate impregnating bag of the present invention with label 1.This embodiment comprises the osed top bag 2 that is made of porous sheet, and above-mentioned flaky material is sealed at periphery 3 places, to form cell 4, is used for holding an impregnated material 5 of getting involved between the sheet material.Sheet material can be to be made of the multiple suitable material of making this class bag, and the representative type material comprises paper.The sealing of sheet material also can be finished with any suitable encapsulating method of the prior art, for example adopts heat-sealing.
But but the impregnated material that places cell 4 can be tea or any impregnated material that other is fit to of for example 2.5 grams.
Sheet material also can be sealed in two zones 6 in cell 4 again, but so that impregnated material that comprises and periphery 3 are inwardly spaced apart.
Hauling rope 7 places between the sheet material of 1 bag of impregnating bag.A part on the hauling rope penetrates cell 4 by 8 places, the position on the periphery, and around near the relative seal area 6 of periphery, pass cell 4 then and at 9 places, position that are positioned at the periphery of the place's of entering 8 homonymies, but position 8 and 9 is relative spaced.In this example, hauling rope 7 has two free ends, and they are fixed on the two layers of paper, to form tongue bars 10 separately.These tongue bars can be chosen wantonly, and hauling rope also can form the osed top ring, and the mode that does not adopt the end to separate.
In use bag 2 is placed container filled with hot water, content is soaked in hot water, and hauling rope 7 is striden on the side that hangs over container with tongue bars 10.When the dipping of content is finished, by tongue bars 10 bag 2 and hauling rope 7 are taken away, during general hauling rope on oppositely spurring tongue bars 10, remaining liquid is extruded from bag 2.In order to remove liquid most effectively, the end of hauling rope 7 is as shown in arrow 11 to be reversed horizontal pulling like that.Pulling force on the hauling rope makes and move towards each other zone 6, the inlet 8 and outlet 9 that is sealed when the size of traction becket bridle reduces.This action also makes the inside drawing of wall of cell 4, thereby cell 4 is shunk, so extrude liquid from cell.The action applied force that should note making the wall of cell 4 to shrink is used to push liquid wherein, rather than hauling rope acts on the material that can flood with simple action.Because hauling rope 7 itself can freely move, rather than is fixedly attached on arbitrary sheet material, so just reduced the danger that when pulling traction rope 7, damages or tear sheet material in bag 2.Hauling rope 7 by means of sheet material to sealing place 6 of sheet material and be detained in cell 4 by sheet material.This sheet material is to the sealing of sheet material, has bigger intensity than the sealing that directly is packaged on the sheet material hauling rope to be obtained, and so just reduced the possibility that hauling rope is pulled through seal area and pulls out bag thus.
Figure 2 shows that an alternative embodiment of impregnating bag of the present invention, wherein shorter at the hauling rope 7 in bag 2 outsides, the single tongue bars 10 that is connected in hauling rope 7 is measure-alike with bag 2.Link on the single tongue bars 10 at the two ends of hauling rope 7, and the latter has local crack along line of centers 12, makes and tongue bars 10 can be torn when using tongue bars 10 that pulling traction rope is so that squeeze out the liquid in the bag then.Bigger tongue bars 10 can fitly rely on bag 2 and fold up so that pack, also can be used as the supporting parts of impregnating bag, when with making it easy to carry after crossing when impregnating bag is given up in disposal.
Figure 3 illustrates another embodiment that in cell 4, has two seal areas 6.Two relative positions 8,9 of hauling rope 7 this moment from the periphery are into and out of cell 4.Two seal areas 6 are on two angles in the cell 4, and hauling rope 7 is not from coming in and going out here.Have, by the opposite basically direction pulling traction rope in edge, the effect of the ring-type hauling rope between seal area 6 and periphery 3 makes bag 2 compress again.
In another embodiment shown in Fig. 4, four seal areas 6 are arranged in cell 4.In this example, seal area 6 is arranged on the every nook and cranny of cell 4, and hauling rope 7 is around crossing each seal area 6, and is arranged between seal area and the periphery 3.7 of hauling ropes intersect in cell 4, and it has formed a complete ring around cell 4 edges like this.When the end of reverse pulling traction rope 7, thereby this ring makes the bag compression with regard to shrinking.In this example, hauling rope has a little single tongue bars 10 that connects its two ends, and this tongue bars can cut off along line of centers 12 parts.
The number that should note the seal area 6 in the cell 4 is not crucial, as long as the length of hauling rope 7 can constitute ring effectively, gets final product so that bag 2 can shrink in use effectively.The number of seal area 6 is few more, and the manufacturing of impregnating bag is also easy more.
Impregnating bag of the present invention can be produced expeditiously on a large scale.When making impregnating bag with usual method, but macerate can place with aerated materials make continuous online, again that the net of another Zhang Lianxu is thereon topped, use such as sealed roller etc. two heat-sealings of throwing the net.In the present invention, hauling rope should be in heat-sealing to be prepended between two nets, and then with the seal area heated sealant of net in bag together.Complete subsequently bag can cut down as usual manufacturing tea bag from network.
As can be seen, impregnating bag of the present invention has the effect of two aspects, promptly can remove remaining liquid effectively in use from bag, and impregnating bag is suitable for being made by High-Speed Automatic metallization processes.Simultaneously also reduced after use the danger that impregnating bag itself is damaged when therefrom removing liquid significantly.
