Description

BAG FOR A BEVERAGE PREPARATION BACKGROUND OF THE INVENTION [0001]

The present invention is directed to a bag for a beverage preparation article as provided in the preamble of the appended claims.

A beverage preparation in the form of a solid feedstock for beverages produced by brewing or extracting is used as a water-permeable bag (filter bag) to prevent the beverage from mixing with this feedstock Packaged. Accordingly, the filter bag can be packaged with a packaging material that surrounds the bag and forms a single protective package for the filter bag. These protective packages can be packaged in larger boxed retail packages. The most common examples of such packages are packages of tea beverages to be produced by brewing or extraction, i.e. packages of tea bags. Also, a conventional rectangular flat protective package to which a string of teabags is fastened is disclosed, for example, in U.S. Patent No. 3,175,911.

When using a bag made from a suitable filter material that contains the raw material for the beverage, the bag is placed in a cup that is poured with hot water or already contains hot water, after which the bag is placed in the filter bag Infused with water as long as the beverage ingredients are dissolved from the contained ingredients.

The problems with these packages are caused by the fact that the raw material inside the filter bag swells and becomes wet when bags are concerned. When the bag is pulled out of the cup, this bag disturbs the places. If you do not use any appliances if you want to squeeze the bag and drain out any liquid remaining in the cup, it is hard to get your hands dirty. Even though the bag becomes more dry by squeezing, some liquid always remains in the bag, dribbling from the bag onto the surface on which the bag is placed.

A number of patent documents disclose solutions to overcome these problems. To overcome this problem, a very common approach is to create a bag of "back openable at the bottom", which can be lowered into the cup while the bag is carried by the string and lifted back into the package Where the package can be used to squeeze the bag and maintain the bag without contaminating the user's fingers, for example as disclosed in International Publication WO 96/01773. However, if the dimensions are determined such that the package is brought close to the dimensions of the dried bag, it is difficult to pull the inflated bag into the package. In addition, if the package is placed in a horizontal position on the table after use, the liquid may still flow through the open bottom of the package.

In addition, teabags are known in which the suspension strings are being guided in such a way that the back can be squeezed dry by pulling the string. This requires special attachment arrangements of special attachments and strings in the bag to obtain a loop for dry pressing the bag as disclosed in US 2004/071830.

International Publication WO 98/04460 discloses teabags that can be ejected by tilting the bag at an angle of about 45 DEG, where the bag and vertical edges form a "tip " directed downward, Water accumulates to form a bed of a kind that produces pressure to more efficiently remove water from the bag. According to the embodiment shown in FIGS. 3A and 3B, the discharge position is obtained by fastening one end of the string away from the center (the symmetrical center line of the bag), and the bag can hang at an inclined position.

In addition, elingated bags are known which, when they are floated, can be used as stitting sticks so that the materials contained in the bag are simultaneously dissolved in the water through the porous walls. For example, document US 2002/0162461 discloses the use of densely spaced micropores (less than 0.5 to 0.35 mm) in the backing material, thereby reducing the effect of surface tension, The substance that has entered the bag and dissolved in the water may be released from the bag by diffusion. The bag may be used to make beverages from water-soluble or extractable materials.

When micropores are used, it is probably possible to reduce the fountain of water from the bag after use without contacting the surface which can trigger dribbling of water out of the bag. When such bags are used for extractable powdered beverage ingredients (such as tea leaves), water can not flow properly through the powder and can not "flush" the powder, It is necessary to release the flavoring agents in one water. The powder should be packed sufficiently tightly in the bag so that the bag is used for stirring in the early stages, but when the powder is wet, the powder will expand and impair absorption of the materials.

For the above-mentioned reasons, especially the powdered materials in which the materials are extracted in water are packed into gauze bags, these bags have a large open surface area and are thin so that water can flow into and out of the bag and loosely The powder to be packed can be submerged. This is the way to correctly pack tea leaves. Unless you want to squeeze the bag dry by fingers or special instruments, the only alternative for dry squeezing is to drain the water from the bag at an oblique position as provided for example in WO 98/04460.

Experiments may show that droplets no longer appear even though the bag contains a large amount of water after the water has been drained off by a sufficiently long (2 to 3 seconds) swing from a relatively open surface bag subjected to water . This is because of the absorbency of the powder and the maintenance of the remainder of the water by the surface tension of the water. However, when the surface of such a bag is touched, a lot of water will come out exactly from the point of contact; In other words, the cohesive surface tension of water is destroyed at the point of contact. The same phenomenon occurs when a bag, seemingly without dripping, is placed on the solid surface to make contact with water in the bag.

All in all, the problem with all bags is that the user does not have to put the bags that have been concerned in the water on special trays or packages So that contamination of the table should be avoided.

It is an object of the present invention to eliminate the above-mentioned disadvantages, which may place such a bag on a table or other place where cleanliness will be maintained, rather than requiring separate trays or squeezing devices A disposable bag for a beverage manufacturing material. In order to achieve this object, the bag according to the invention is characterized mainly in that it can be provided in the features of the appended claim 1.

The bag comprises a support surface formed as an impermeable structure. This support surface opposes the counter surface, on which the wet back is placed after concern. The support surface provides support points for supporting the bag to the bag, and will maintain the support surface in the lowest position against the counter surface. The impermeable structure of the support surface is such that it extends upwardly (over the support points) as a collar of the given height, surrounds the entire bag in a horizontal direction, and the water flows out of the bag from the lowermost point of the wet- ≪ / RTI >

The impermeable structure is the integral part of the bag material (the wrapping material surrounding the beverage preparation material), which retains permeability in other parts, i. E., Has a filter structure. In one alternative, a bottom portion of the vertical bag (i.e., a bag whose height is greater than the largest dimension of the bag in a direction across the height) or the bottom portion of the polyhedral bag is formed as an impermeable structure, The side walls are permeable (to have a filter structure) to disturb the beverage preparation material contained in the bag, and the components thereof will dissolve in water. The impermeable zone of the bottom portion extends at a suitable height in the direction of the side wall of the bag and forms the aforementioned collar that extends at a given height and surrounds the support surface formed by the bottom portion. Such a bag can be, for example, a general shape of a conventional teabag made by folding and seaming the bag material of the bag, or a bag having the shape of a tetrahedron or other polyhedron. After the buoyed bag is placed upright on the table or other counter surface, the water that tends to leak from the beverage preparation will be held in a kind of "trough" inside the impermeable bottom.

The impermeable bottom portion may be provided, for example, at the bottom of a beverage-manufacturing bag having the shape of a teabag, or a bottom surface of a bag having a tetrahedron or other polyhedron shape to encompass the bottom. This thus covers a small portion of the surface area of the lapping material of the bag and does not impair the efficiency of worrying. This is so that the bottom portion lies at the bottom of the counter top surface against the counter surface and covers the area of one side of the polyhedral backing and the region extending from the side in the height direction on the bottom portion of the other side, And a region extending from the bottom in the height direction on the lower portion of the upright sidewall. The impermeable structure also makes it possible to extend from the bag onto a large support surface, e.g. one large side of a flat bag. The bag is thus placed in a horizontal position on the support surface against the counter surface. In this alternative, the surface area available for concern is smaller.

In order to dissolve the ingredients into the water from the bag and then to control the discharge of water from the bag better, the bag is arranged so that when the center of mass of the bag is placed by gravity below the suspension point, Includes two suspension points for determining positions; A setting position in which the bag is suspended by the impervious support surface facing downward, and a discharge position in which the support surface is rotated at a predetermined angle with respect to the setting position. For example, at the discharge position of the upright bag, the side wall of the bag on the impermeable bottom portion is rotated at a smaller angle with respect to the horizontal plane than at the setting position, and the lower surface of the bottom portion is inclined corresponding to the side, have. The bag may be inclined or horizontal, or even at a discharge position where its upper end may be downward, the water may be more easily discharged from the bag after concern through the permeable packaging material. When allowed by the internal dimensions of the cup or glass, this position can also be used as a venting position where the beverage preparation material contained in the bag is more easily in contact with water in the cup or glass, When accumulated on the permeable side wall, water submerges the beverage preparation material contained in the bag, and the constituents of the production material are better dissolved in the water. In this position, when the raised bag is lifted out of the water, it can be dried and dried at the same position. In addition, the bag from another position in the water can be lifted out of the cup or glass and rotated to the discharge position.

The setting positions and ejection positions obtained by the different suspension points can be utilized in all backs regardless of their general shape. Thereby, at the setting position, the support surface is located at the lowermost position toward the counter surface, and at the discharge position, the support surface is rotated to another position so that the permeable area in the package material is further rotated toward the horizontal plane.

When the bag is rotated from the discharge position to the setting position, the beverage preparation material contained in the bag will again be packaged on top of the watertight bottom portion, causing a leak problem when the bag is set on the impermeable support surface against the table or other counter surface I will not. The water capable of leaking from the wet beverage preparation material will be held at the top of the impermeable structure and will not leak at the sides because the impermeable structure also has an upward dimension in the form of a collar.

The suspension point of the setting position is on the bag on the side opposite the support surface and the suspension point of the discharge position is closer to the support surface of the bag, for example, from the upright bag to the bottom part or to the above mentioned point on the side wall. Preferably, the support points are disposed in a impervious structure of the bag.

Indeed, the suspension points that support the bag against gravity can be the fastening points of the suspension string. For example, it is possible to use one suspension string that forms a loop between fastening points. This also allows to precisely adjust the angle of the discharge position of the bag by simultaneously applying a bearing force on both suspension points, and the bag can also be precisely positioned at a desired position, which can be in a different form from the setting position and the discharge position .

The bag itself is a disposable bag, and the bag is made by opening a shim that has just been formed by tearing the package material or sealing the edges of the package material together, or by a rivet, self-adhesive label, knot of binding material or other corresponding closing member By encapsulating the package material surrounding the solid beverage preparation material within the bag in such a manner that it can be opened by opening different types of shims that have been formed by permanently sealing the package material. The bag may be made of a permeable region and a blank comprising a watertight region by folding and seaming to form a closed structure and a lower portion of the closed structure is provided with a water impermeable structure constituting a watertight region of the blank. The bag is formed so as to have a structure with a sufficiently large supporting surface so that the bag can be held at the setting position. The bottom surface of the lower portion is sufficiently large and an upright bag can be made to support the bag in the upright position.

The blank can be embodied as a combination of a water permeable region (region having a filter structure) and a watertight region by covering the blank originally composed of a material having a filter structure as a whole and a film made of a watertight material as a whole, Gt; can be maintained outside the area covered by < RTI ID = 0.0 > Or by modifying the material, starting from a blank made of the original watertight material, such that the permeable area is formed on a portion of the surface area of the blank, leaving an unmodified area of the watertight material outside. The permeable region may be modified in the blank material, for example, by penetrating through the applied hole density and hole size, such that the combined effect provides a sufficiently open surface area. It is also possible to modify a material having a filter structure normally for the desired portions that become impervious, for example by coating techniques, without having to adhere the separate impermeable finished pieces of the material film onto the filter construction material.

A tight material film can be fastened throughout the package material or pointwise.

The blanks may be provided as one after the other as blank webs, from which the blanks of the given size are separated, folded, filled, and finally sealed at the appropriate stage by the solid beverage preparation material Bags.

Figure 7 illustrates how the invention can be applied to bags of any shape.

The filter manufacture is packaged with a filter bag (1) mainly composed of impermeable material. The beverage preparation material is a solid state, such as powder or particles or a variety of vegetable portions from which the beverage can be made by concern of the bag 1 in water for a suitable period of time and the beverage ingredients are dissolved in the water from the bag. This process is often referred to as infusion. While tea and various spiced tea and herbal tea are examples, the present invention is not limited to bags containing ingredients for such beverages.

The bag 1 may have the general shape of a conventional flat filter bag 1 or a polyhedral bag (e.g., a tetrahedral bag, a pyramid bag) that is becoming increasingly popular in recent years. The bag may be made and filled by prior art automation devices, starting from a back-blank, which is water-impermeable, i. E. A water-tight zone is pre-provided on a portion of its surface.

The bag 1 is a disposable closed bag formed by folding and seaming of an appropriate package material (lapping material), within which the beverage preparation material is packaged when the bag is partially opened in the molding step. The beverage preparation material is packaged in such a manner that only a portion of the inner volume of the bag is filled (the degree of filling is only half or even less than the cut calculated based on the volume of production that is free to settle). This improves the dissolution of the ingredients from the beverage preparation material. The bag of Fig. 1 is an upright bag having the shape of a conventional teabag. The bottom portion 3 of the bag is impermeable structure 1b to a height imparted from the lowermost bottom. Structure 1b has an upward dimension; That is, the structure is impervious and has a collar extending to a given height. Impermeable structure 1b impermeable to water is an impermeable region and is arranged in a part of the surface area of the package material so that in the package material the material in the finished bag also has a horizontal plane determined by the support points on the bottom of the bag And arranged in such a way as to constitute an impervious collar to prevent leaking of the liquid.

On the impervious collar of the bottom part 3, the bag extends directly into the side walls 2 formed of the permeable area 1a with the filter structure. The figure also shows two suspension points; A suspension point A corresponding to the setting position and a suspension point B corresponding to the discharge position. The suspension point A corresponding to the setting position is located at the upper end 2a of the bag on the symmetrical center line C; That is, when the bag is supported from this point, the bag hangs on the bottom portion 3 facing downward. The suspension point B corresponding to the disturbance position / ejection position is such that when the bag is supported from this point, the side wall 2 of the bag, which is located in the region 1a having the filter structure, And is placed at the point to be rotated at a small angle. This angle may be, for example, zero, where the sidewall is approximately horizontal. This angle can also be negative, where the sidewalls are directed downwardly in an inclined manner. In Figure 1, the suspension point B of the pan / tilt position is at the edge of the watertight bottom portion 3.

In the case of the flat bag shown in Figs. 1-3, the permeable side wall (with the filter structure) comprises large front and rear walls, which approach each other in a wedge fashion and upward, 2a and the worrising position / ejection position is such that the front and rear walls (in the region 2 having the filter structure) are folded so that its angle with respect to the horizontal plane is reduced when the back is supported from the suspension point B Are arranged in such a manner that the side edges 2b of the side walls 2b are inclined. This side edge is in a setting position (FIG. 3) when viewing the bag directly from the front (approximately 90 degrees) and is inclined to a substantially horizontal plane (angle 0) in the worst position / out position (FIG. 2). Thus, at the side edges 2b of the front and rear walls, the folds form a wedge in the interior of the bag, which allows water to pass through the material with the filter structure as it exits from the bag to the cup, . To achieve this, the suspension point B of the pan / tilt position may be located at the other edge of the bag so that the opposite side edge 2b of the bag is directed downward at the panic position and the discharge position. The suspension point B may be disposed, for example, at the edge of the bottom portion 3 between the front wall and the rear wall.

Suspension points A and B may be marked or determined in the bag in a suitable manner. Suspension points may be, for example, holes or loops that can be caught and suspended. Advantageously, the suspension points A, B are connected to the suspension string 4; That is, these points are the fastening points of the same suspension string. Thus, by means of the suspension string, the angular position of the side wall of the bag with the filter structure can also be adjusted by keeping the suspension string 4 in place.

Figure 2 shows the worrying position and the dripping position, wherein the bag is kept in water and is discharged drier. In this position, the water in the cup or glass is easily penetrated into the bag to dissolve the components of the beverage from the bag. If the bag is lifted from the water and positioned at the same location and shaken is possible, excess water may fall back into the cup or glass through the bag's permeable side wall.

The bag shown in Fig. 3 is the setting position, where the watertight bottom portion 3 is at the bottom and a bag in which excess water can be discharged can be placed against the counter surface 5, e.g. the table. Thus, the watertight bottom portion 3 functions as a support surface against the table. In this position, the bottom portion 3 prevents water from leaking from the beverage making material inside the bag. In addition, the watertight bottom portion prevents direct contact between the surface and the wetted beverage preparation material, which can cause seepage of water onto the surface.

The bag in Fig. 1 has a general shape of a bag similar to a normal tea bag, which is formed by folding an intermediate form having a flat hose shape, The shape can thus be made by wrapping the flat formed from the flat blank so that the seam formed by the overlapping edges of the blank is left in the center of one of the flat surfaces of the hose, And the opposing flat surfaces form the outer-most forward and rear surfaces (front and rear walls) of the tee bag. The ends of the hose are joined together, and these ends form an upper end 2a of the bag. In the transverse direction, in the middle of the hose, there is a zone of impermeable region 1b surrounding the hose and constituting the lowermost bottom portion 3 (at the setting position), which is impermeable in the finished bag . The hose is folded so that a sufficiently large underside is left in its central portion; That is, folding lines L2 of their own are left between the bottom portion and the front side wall and between the bottom portion and the rear side wall, so that the bag is kept upright with sufficient space. These two folding lines L2 extend inside the impermeable region 1b, where the impermeable collar is formed for the bottom portion 3 extending above the predetermined length. Corresponding collars are formed in the lower ends of the inner walls facing left and behind each other in the outermost front wall and the outermost rear wall.

Between the folding lines L2, the bottom surface of the bottom consists entirely of the impermeable region 1b. In addition, the upper surface of the bottom on the opposite side left inside the folded hose consists of the impermeable region (3). The bag material of the bag may also be wholly sealed together in the area between the fold lines L2 before filing where no beverage preparation material is present at the bottom and the bag 1 is in some sense "Quot; double back "or" double pouch ", wherein the enclosed spaces, which include the beverage preparation material and are entirely underneath, are formed between both the upper end 2a of the bag and the folding lines L2. In addition, bags are known in which bags are not sealed together between folding lines (L2), but bags are formed in the same manner by elongated hoselike pieces from different perspectives.

The suspension point B for determining the discharge position is arranged at one point at the edge of the bottom part in the bag of Fig. 1, and at this point, between the folding lines L2, in the center fold L3, To raise the bottom slightly upward. The suspension points A and B are arranged in the same vertical plane, which divides the bag into two symmetrical halves, and between the front and rear walls and parallel to each other, To the bottom. 1 also shows that the impermeable support surface does not need to be uniform against the support 5 but there are support points (folds L2) facing the counter surface and within the support points, the mass center of the bag It would suffice to be positioned as shown in the horizontal projection.

Figure 4 shows a blank web sufficient to make the bag shown in Figure 1 in the manner described above. The bags are formed by cutting successive rectangular blanks in the cutting lines S from a blank web, and the rectangular blanks are folded along the folding lines L1 to form flat hose shaped intermediate shapes open at both ends. The hoses are folded in the middle along the second folding lines (L2) traversing the preceding folding lines to form the bags. The blank web is made of a material having a filter structure and the central portion of the filter structure is made up of a watertight container having a predetermined width that forms the impermeable zones 1b in the blanks extending in the longitudinal direction of the blank web and separated from the blank web Are covered in strips of material in the direction of the folding lines L2. The second folding lines L2 are left inside the impermeable areas and an edge zone is left between the outer edges of the areas Ib and the folding lines L2 and the zone extends in the direction from the bag to the side walls Construct a color.

The material film constituting the impermeable zones 1b may be, for example, plastic. This material can be, for example, a plastic film whose outermost surface is water repellent or water repellent. The material is attached to the web material having a filter structure, for example, by heat sealing. In addition, packaging materials with filter structures are known, these materials can be ultrasonically sealed to close the bag, and the impermeable material film can also be attached to this material by ultrasonic sealing.

The material film forming the impermeable regions can be attached to a packaging material having a filter structure over the entire surface or point shape. Also, in the finished bag, if these edges constitute an upwardly directed collar that prevents water from leaking, the material film can turn off the packaging material at its edges.

If the back is formed of a blank, the beverage preparation material may be fed into the bag when the bag is in a hose-like intermediate form. The material is held on the back side of the bag when it is sealed upward by sealing the ends of the hose together after the bag is filled. If the hose is upwardly sealed within the central region of the bottom, the beverage preparation material is introduced through both of the open ends of the hose before the bag is sealed.

Figure 5 shows a different kind of blank web used to make bags in the shape of a tetrahedron and wherein the material of the watertight bottom portion 1a is such that when the blanks are cut out and folded, A watertight bottom portion 3 is formed on the bottom of the tetrahedron and has a collar extending at a predetermined height. In the blank, the watertight region 1b is formed by a strip having a given height extending parallel to and parallel to the base of the triangular region and the triangular region. The bottom is formed within the entirety of the triangular portion, and the collar is composed of areas of the strip extending to the sides and borded by the sides of the triangle. The tip of the triangle is blunt: that is, the sides of the triangle are not bonded to the outer edge of the blank. Also the tip of the triangle is imperfectly held at both edges of the base of the triangle; In one edge, they are connected by strips, and at the other edge, the base and sides of the triangle are bounded by the edges of the blank. The blanks are folded in the middle along a first folding line (L1) extending to the joining point of the triangle and the strip, and are upwardly sealed at the side edges and bottom edges which limit the base of the triangle and the strip, , The beverage preparation material may be inserted into the bag through a mouth that is kept open. Thereafter, the white mouse is closed by pressing the folds at the ends of the opening against each other, wherein the direction of the mouse is rotated at right angles to the original, and one edge of the tetrahedron is formed. 5, the broken line shows the contour of the inside region of the watertight zone 1b that forms the bottommost bottom, which region is the outer boundary of the region forming the watertight collar extending upward from the plane of the bottom, .

Figure 6 shows a bag for a beverage preparation material folded from the blank of Figure 5; The side wall 2 is formed by three triangular faces of a tetrahedron extending upward. The original folding line L1 extending in the middle of one face is shown as a broken line. In this bag, the suspension point A of the setting position is at the top 2a and is the "vertex" of the tetrahedron, and the suspension point B of the worst position / Edge 2b extending downward from the centerline of one side of the sidewall 2 of the tetrahedron where it is directly on the opposite side and extending in the same vertical plane as the centerline, Water can be discharged through these edges. Also in this case, the suspension point B is disposed in the impermeable region of the bottom portion. Also in this case the suspension points A and B are joined by the suspension string 4 which is permeable to the apex of the tetrahedron at one end A and to the apex of the tetrahedron at the other end Is fixed to the material.

In principle, a bag that functions in a corresponding manner can be formed of a cube, wherein one side thereof forms a support surface, its impermeable structure is continuous, and the part of the region of four different sides joining said one side As shown in Fig.

The present invention is not limited to backs having only the shape shown in the figures, and can be applied to backs of various shapes. Fig. 7 shows a bag 1 whose surface is not a polyhedron but a curved, for example round or oval. Also, this kind of bag is impervious and is provided with a support surface that attacks the counter support at the set position and a region that forms a collar extending upwardly therefrom

Impermeable filter structure is obtained by attaching impermeable material onto the extent structure of the region 1b or by performing coating or surface treatment to the extent of this region 1b Once formed, the blank material with the filter structure may be comprised of known materials used, such as loose nonwovens or teabags, such as nonwoven or otherwise produced mesh fabrics. As a package material having a filter structure, for example, a gauze-like material suitable for food, ultrasonic and heat sealable, commercially available from Ahlstrom under the trade name BioWeb and made of polylactic acid (PLA) ) It is possible to use nonwoven fabric. In addition, other materials and methods for forming the water permeable region 1a and the watertight region 1b with the same manufacturing material of the bag are feasible.

The watertight region 1b may also be biodegradable if the permeable region 1a of the packaging material is biodegradable. If the same permeable packaging material film is used, it can be achieved by selecting a membrane made of a biodegradable material. If a watertight region is formed by adhering a watertight material piece onto an impermeable and biodegradable packaging material (already having a filter structure), this can be done, for example, by selecting a biodegradable plastic. Biodegradable plastics such as polylactic acid (PLA) or some polyhydroxy-alcanoate (PHA) can be used as the biodegradable materials, in view of both the water permeable region and the watertight region. Although PLA and PHA are hydrophobic as such, if they want to increase the water repellency of the outer surface of the watertight region, they can be carried out either by coating or other surface treatment techniques. The packaging material having the filter structure can also be made of biodegradable natural fibers, wherein the piece of material to be adhered as a watertight region on the material can be composed of a biodegradable plastic such as PLA or PHA. Such a piece of material of the biodegradable plastic may be a surface treated by coating or other surface treatment techniques.

In addition, the present invention is not limited to bags having only suspension points for determining the setting position and the discharge position, but may be applied to bags comprising a beverage preparation material designed to be freely disposed by hand, Or " soaked "within the glass, is lifted by the spoon or fingers and held in the discharge position and then placed by the fingers or by the instrument in a setting position having an impervious support surface against the counter surface .

And may be formed as a watertight support surface and a watertight collar when the bag is formed, filled with the beverage preparation material, and sealed in such a manner as shown in Figures 1 to 7 The impermeable structure 1b, which has been added as a separate piece of material, can be arranged to suit the flexible packaging material. The impermeable structure can also be, for example, a "tray" or "trough" of plastic with an upwardly extending collar, wherein the preformed bag forms a corresponding impermeable structure with corresponding functions In such a way that it can be secured in the area of its bottom at the right place in the package material.

In a packaging material surrounding the beverage preparation material, the surface area of the permeable area is preferably greater than the surface area of the impermeable area. The ratio of the areas is preferably greater than 3, more preferably greater than 5.

The bags may be packaged one by one in one protective package in the same manner as the teabags, or several bags may be packaged in one larger package at a time.
