Definitions

  • the invention relates to infusion bags made of filter material, in particular filter paper, for producing beverages in a container made of extractable substances, in particular ground roasted coffee, legs connected to one another at the upper end by U-shaped folding of the double-layered filter paper, with partial chambers for receiving a partial portion of the roasted coffee or the like are formed.
  • the invention has for its object to make an infusion bag available, which is particularly suitable for the quick preparation of coffee beverages from roasted coffee, without a reduction in quality compared to conventionally prepared coffee beverages.
  • the infusion bag according to the invention is characterized in that the subchambers are connected (together) with their upper edges to a rigid actuating handle, such that the subchambers perform opposite transverse movements supported on a container base (cup base) by moving the actuating handle up and down.
  • the invention is based on the finding that an infusion bag for the preparation of, in particular, coffee beverages must be designed such that a "pumping movement" which is not usual for the preparation of beverages with the aid of infusion bags can be transmitted to the infusion bag with the aid of the actuating handle that a flow effect and thus a short-term effective extraction is achieved by this movement.
  • the infusion bag is therefore designed according to the invention so that by moving up and down the largely rigid actuating handle between closed partial chambers with partial portions, a cavity which changes in shape and size is created - pump chamber. Water flows in these through the movement described and exits again, namely through the partial chambers by. Due to the up and down movement of the actuating handle, a deformation pressure is exerted on the infusion bag supported on the container base (cup base), which leads to an enlargement and reduction of the cavity (pump chamber) and thus to the formation of underpressure and overpressure therein.
  • the partial chambers are connected to one another or to the actuating handle at the upper and lower transverse edges, so that a variable cavity is formed as a pump chamber between the chambers.
  • the effect sought with the invention can be improved in that the cavity (pump chamber) formed between the partial chambers is provided on the open sides with sealing tabs which act as a check valve during the up and down movements of the operating handle.
  • a higher internal pressure can build up in the pumping chamber, which forces the flow of water through the subchambers to the outside.
  • An infusion bag designed in this way is produced according to the invention from two simply designed blanks made of filter material (filter paper).
  • the subchambers are closed all around by welding or adhesive seams.
  • An outer blank is formed with a greater width than an inner blank, in such a way that a lateral strip protrusion is formed which, after being folded over, forms the sealing flaps (valve tabs).
  • the partial chambers are kept at a greater distance from one another in the lower region, namely by a strip of filter material free of roasted coffee, preferably formed by a correspondingly wide lower transverse seam.
  • the subchambers can make larger transverse movements to one another during the pumping movements.
  • the shown infusion bags made of sealable filter paper are primarily intended for the preparation of coffee beverages from ground roasted coffee.
  • Each infusion bag consists of several, namely two sub-chambers 20 and 21 which each serve to hold a portion 22 and 23 of roasted coffee.
  • the total amount of roasted coffee corresponds to the portion of coffee required to produce a coffee beverage, in particular a portion of a cup.
  • the total portion of ground roasted coffee is approximately 7.5 g.
  • the subchambers 20 and 21 are formed by chamber walls 25 and 26 or 27 and 28 made of filter material, in particular filter paper.
  • the chamber walls 25 ... 28 are laterally connected to one another by side seams 29 and 30 and above and below by transverse seams 31 and 32, so that the partial chambers 20, 21 have an internal volume of sufficient dimension.
  • the partial chambers 20 and 21 are connected to one another in the region of the lower transverse seams 32.
  • the upper transverse seams 31 are fastened to an actuating member, namely an actuating handle 33.
  • the actuating handle 33 is designed such that a certain pressure can be exerted on the structure consisting of the subchambers 20, 21 when the infusion bag is being handled, without causing significant deformations of the actuating handle 33.
  • this preferably consists of plastic, e.g. B. hard PVC.
  • the actuating handle 33 can be punched out as a shaped piece, for example from plate material.
  • the operating handle 33 is provided with a circular widening 34 at the upper end.
  • the actuating handle 33 is provided at the lower end with a crossbar 35 which extends approximately over the width of the subchamber 20, 21.
  • the upper transverse seams 31 are connected to the transverse web 35, in particular welded or glued to the outer sides thereof.
  • the handling of the infusion bag designed in this way results primarily from FIGS. 3 and 4.
  • the infusion bag is gripped in the area of the widening 34 of the actuating handle 33 and immersed in the area of the partial chambers 20, 21 in the cup 24 filled with hot water.
  • the lower edge of the subchambers 20 and 21, näm Lich the interconnected transverse seams 32 are supported on the cup base 36.
  • the halves of the infusion bag formed from the partial chambers 20, 21 are moved in opposite directions to one another.
  • a cavity comes into effect, which is formed between the units consisting of the subchambers 20 and 21 and which acts as a pumping chamber 37. This changed in size and shape during the up and down movements of the operating handle 33.
  • the relatively narrow pump chamber 37 in the starting position (FIG. 2) is widened, as a result of which brewing water not only flows into the pump chamber 37 via the free, open sides, but also through the partial chambers 20, 21 through.
  • the pump chamber 37 is reduced again, as a result of which the water that has penetrated flows laterally and outwards through the partial chamber 20, 21 (FIG. 3). With the renewed upward movement, the water flows in the opposite direction, as shown in FIG. 4.
  • shut-off flaps 40, 41 and 42, 43 installed and arranged so that they are moved into a closed position (Fig. 6) when pressurized by the brewing water located in the pump chamber 37 and pushing outwards.
  • the butterfly valves 40 ... 43 therefore act like check valves.
  • the shut-off tabs 40 ... 43 - made of paper, plastic or the like - are attached with outer edges to the upright side seams 29 and 30 of the partial chambers 20, 21, specifically on the side facing the pump chamber 37.
  • the attachment is such that in the starting position when the infusion bag is folded flat, the shut-off tabs 40 ... 43 are also folded flat between the subchambers 20, 21, bearing against the facing inner chamber walls 26 and 27.
  • shut-off flaps 40 ... 43 are moved into a position in which they are connected on the one hand to the side seams 29 and 30 and on the other hand with free, inner sealing lips 44, 45 approximately in the central plane of the pump chamber 37 lie together.
  • This closed position of the shut-off flaps 40 ... 43 is favored or stabilized in that the shut-off elements in question converge at the bottom and at the top, namely are bound between the transverse seams 31 and 32.
  • the subchambers 20, 21 come into a relative position to one another in which water flows into the pump chamber 37 from the outside, specifically via the side openings 38, 39.
  • the shut-off flaps 40 ... 43 are moved in the direction of the inner chamber walls 26, 27, so that the inflow effect takes place unhindered (Fig. 7 and 8).
  • the partial chambers 20, 21 including shut-off flaps 40... 43 consist of two blanks 46 and 47 made of filter paper.
  • the blank 46 lying on the outside in the finished infusion bag is dimensioned with a greater width than the inside blank 47, such that blank strips 48 and 49 protrude laterally beyond the inner blank 47 in an intermediate position according to FIGS. 11 and 12.
  • the blanks 46 and 47 are connected in this position by the side seams 29 and 30 and by the transverse seams 31 and 32, the latter combined to form a common transverse seam of double width, after the partial portions before or during the connection of the blanks 46, 47 to one another 22, 23 was filled into the subchambers 20, 21 that were formed.
  • the cut strips 48, 49 are then folded over against the free side (inner side) of the inner cut 47 (FIG. 13) when the structure is elongated. This creates the shut-off tabs 40 ... 43, the cutting strips 48, 49 being dimensioned such that they extend approximately to the middle of the partial chambers 20, 21.
  • the inner blank 47 can also be formed with a larger width, with the blank strips on the edge being folded inwards in order to form the shut-off tabs 40 ... 43, as described.
  • FIGS. 15 and 16 An embodiment of the infusion bag which is also particularly suitable for large-scale industrial production is shown in FIGS. 15 and 16, each in the cross section of a partial chamber 20, 21.
  • the blanks 46 and 47 of the same width or the same size are made in the manner described by welding or gluing connected to one another to form the partial chambers 20, 21 and to accommodate the partial portion 22, 23.
  • material strips 50, 51 are applied to the (later) inner side or to the inner blank 47 and in the region of the longitudinal side seams 29 , 30 connected to the blank 47.
  • the strips of material 50, 51 - made of paper, plastic or the like - are so wide that they extend almost to the central plane of the partial chambers 20, 21.
  • the continuous structure designed in this way is then severed in the region of adjacent transverse seams 32, so that units, for example in the embodiment of FIG. 11, are produced - without cutting strips 48, 49. Folding in the area of the lower transverse seams 32 creates the infusion bag, to which the actuating handle is still to be attached.
  • the production of such infusion bags can be carried out as shown schematically in FIG. 17.
  • the web-like material for forming the blanks 46 and 47 is continuously drawn off from bobbins 52 and 53.
  • the webs are brought together and connected with one another to form the side seams 29, 30 and the transverse seams 31 and 32, the coffee portions or partial portions 22, 23 being simultaneously introduced into the partial chambers 20 via a filling funnel 56 , 21 can be filled from above.
  • FIG. 18 shows details of the production of infusion bags from a continuous material hose 59 from (sealable) filter paper in individual process stages I ... VI.
  • the material hose 59 is formed on a tubular filler nozzle 60 from a flat, strip-shaped material web 61 and at the same time is provided with a hose seam (not shown) running in the longitudinal direction of the material hose 59 in a conventional manner.
  • the material hose 59 is moved in sections on the filler nozzle 60, namely pulled downwards. During a standstill phase, a portion 22/23 of the roasted coffee is filled into the material hose 59 via the filler nozzle 60. Then a cross seam 31 or 32 is made between successive partial portions 22, 23 in the area below the filler nozzle 60 to produce the subchambers 20, 21. Furthermore, in the area of the (upper) cross seam 21, the material hose 59 is cut so that elongated structures are included two filled partial chambers 20, 21 arise.
  • process step III After folding over into a horizontal position in accordance with process step II, they are folded in a U shape in the area of the lower or middle transverse seam 32 (process step III).
  • the actuating handle 33 is fed in from above, in such a way that the transverse web 35 reaches the area between the upper (half) transverse seams 31.
  • the sealing members 62 are used for renewed sealing in the area of the transverse seams 31, connecting them to the crosspiece 35 of the actuating handle 33.
  • the infusion bag according to process stage IV is now completed.
  • the actuating handle 33 is then pivoted via an intermediate position according to V into a packable position VI and in contact with one of the subchambers 20, 21. Then the finished infusion bag is wrapped in an aroma-tight film packaging.
