Definitions

  • the invention relates to a cleaning agent product comprising a water soluble pouch according to the preamble of claim 1.
  • Cleaning agents for laundry, dish washing, floor cleaning and the like are used in private households in a liquid or solid state form. Such agents are provided in bottles for liquids or in boxes for powders, which allows a free and unrestricted dosing by the user. Besides this, that packaging cost is low. However, many consumers feel uncomfortable when having to find themselves the right dosing, and there is some risk of a wrong dosing applied. In addition, the liquid or powder tends to spill during handling, which requires additional cleaning work.
  • packaged dosing units were developed and found a good acceptance by the users, wherein pressed powder tablets are individually packaged in small single plastic foil sachets or pouches.
  • the pressed powder tablet could be taken out by the user and inserted into the clothes washer or dish washing machine without caring about the required dose.
  • tearing up the foil sachet is quite often not easy, especially when having wet hands.
  • the plastic sachets require a solid state filling and are not practical for liquid cleaning agents in single unit doses. The opened sachets need to be disposed of, which is regarded as uncomfortable, and which adds to environmental burden.
  • cleaning agent products comprising a water soluble pouch became more and more popular.
  • the water soluble pouch is filled with single unit doses of the required cleaning agents and can be inserted into the machine without opening the pouch. During the washing process and upon contact with water, the pouch dissolves and sets the cleaning agents free. The handling of such pouches is very comfortable. Without the need of opening the pouch, the manufacturer is not limited to solid state tablet fillings, but is free to provide a powder or even a liquid filling.
  • Pouches each having two or more separate chambers can be produced in order to separate different agents until they are released into the washing water. In specific, multi chamber pouches allow the use of both a powder and a liquid filling within a single unit.
  • a powder or liquid filling does not have any own form stability.
  • the form stability has to be created by the pouch itself.
  • the problem of form stability is even worse with multi chamber pouches, since the elastic divisional sealing strip between two adjacent chambers acts as a hinge, which tends to make the product flexible to an undesired extent.
  • a multi chamber pouch made of injection moulded water soluble material has been proposed in the past, wherein the injection moulding process leads to quite high wall thicknesses. These wall thicknesses add to form stability even in the area of the divisional sealing strip.
  • the injection moulding process is cost intensive and requires a costly amount of water soluble material to produce the pouch.
  • multi chamber pouches are known made of water soluble, deep drawn foil. Due to the low foil thickness and the easy deep drawing process, the cost contribution of the pouch to the entire product is quite low. However, the comparable thin foil is flexible especially with respect to bending. This holds true in particular for a side by side arrangement of two or more pouch chambers being formed in a thermoformed water soluble foil arranged in two stacked foil layers.
  • Such pouches in different embodiments are known for example from EP 1 375 637 A1 , wherein multiple side by side arranged chambers are separated by divisional sealing strips of two stacked and sealed foil layers. Due to their low total thickness and the resulting bending flexibility such divisional sealing strips may act as undesired hinge lines.
  • a multi chamber pouch in a double layer configuration has been proposed.
  • One chamber is stacked over one or two other chambers, which leads to a mechanically robust and nearly non bending flexible product.
  • the stacked configuration requires three layers of foil, at least two of them being deep drawn in a plastically deforming manner to form the different chambers, while the third foil as an intermediate foil separates them.
  • the deep drawing process of at least two foils is cost intensive, while the need for three foil layers in terms of required material adds to the total product costs significantly as well.
  • the object of the present invention is to provide a multi chamber cleaning agent product comprising a water soluble pouch with improved structural form stability and reduced material and production effort.
  • a cleaning agent product comprising a water soluble pouch having a first chamber and a second chamber being separated from the first chamber, wherein the first chamber and the second chamber are each filled with a cleaning agent, wherein the pouch is made of a water soluble base foil and of a water soluble lid foil being tightly connected to each other, wherein the base foil is deep drawn in a plastically deforming manner to form the first chamber and the second chamber, wherein the first chamber comprises a first base area, the second chamber a second base area and the entire cleaning agent product a third base area, wherein the first base area of the first chamber comprises a concave section on its side facing the second chamber, wherein the second base area of the second chamber comprises a convex section on its side facing the first chamber, wherein the convex section of the second chamber extends into the concave section of the first chamber.
  • the second base area of the second chamber has aside to its convex section at least one concave section adjacent to at least one convex section of the first base area.
  • the pouch is made of two layers of foil only, which reduces manufacturing cost and effort.
  • the thin foil is flexible especially with respect to bending.
  • the convex base area section extending into the concave base area section, and the second base area of the second chamber having aside to its convex section at least one concave section adjacent to at least one convex section of the first base area lead to a separating strip between both chamber base areas without a straight line.
  • the missing straight line form of the separating strip produces a bending stiffness of the whole product, although the separating strip taken alone does not have any technically relevant bending stiffness by itself.
  • the circular base area of the whole product maximizes the mass concentration of the filling with minimum required foil material.
  • the mass concentration in conjunction with the increased bending stiffness leads to a product with high structural form stability, which therefore can easily be handled by the user.
  • a separating strip is present having a mean strip width.
  • the convex section of the second chamber extends into the concave section of the first chamber by a first extension width related to the mean strip width.
  • the first extension width is at least approximately equal to or greater than the mean strip width.
  • a separating strip is present between the first chamber and the second chamber providing along the separating strip a sealed joint with a mean seal width to tightly connect the lid foil to the base foil.
  • the convex section of the second chamber extends into the concave section of the first chamber by a second extension width related to the mean seal width.
  • the second extension width has at least the double value, in particular at least the triple value of the mean seal width.
  • both definitions of the minimum required extension width of the convex section into the concave section are based on different points of view: For manufacturing reasons, the separating strip width must be greater than the seal width. During manufacturing, the separating strip width is relevant for the geometric determination of the chambers base areas. Based on this point of view, the first of the above mentioned definitions relates the minimum required extension to the separating strip width. After manufacturing, the internal pressure of the filled cleaning agents inflates the chambers to an extent, that both chambers are separated from each other by the width of the sealed joint. Based on this point of view, the second of the above mentioned definitions relates the minimum required extension to the seal width. Both definitions, in sum or as an alternative, provide a minimum required extension width of the convex section into the concave section, which leads to the desired form stability.
  • the separating strip and/or the sealed joint have at least along the major part of their length a constant strip width and/or a constant seal width respectively.
  • Said constant width leads to a constant width between adjacent chamber walls.
  • the first chamber has a first depth and the second chamber a second depth.
  • the smaller one of the two depths is greater than the mean strip width at least by the factor of three, and in particular is at least approximately greater that the mean strip width by the factor of four.
  • the first chamber has a first depth and the second chamber has a second depth.
  • the smaller one of the two depths is greater than the mean seal width at least by the factor of six, and in particular is at least approximately greater that the mean seal width by the factor of eight.
  • the first chamber and/or the second chamber have at least at their side facing the respective other chamber a wall section with a draft angle being ⁇ 7° and in particular being at least approximately 5°.
  • a draft angle being ⁇ 7° and in particular being at least approximately 5°.
  • the second base area of the second chamber has aside to its convex section two mirror symmetrically disposed concave sections adjacent to two mirror symmetrically disposed convex sections of the first base area.
  • the convex and adjacent concave sections are wedged together, which adds to the sought structural form stability.
  • the quotient of the first base area and the second base area is in a range from 1,4, inclusive, to 2,4, inclusive, preferably in a range from 1,7, inclusive, to 2,1, inclusive, and is in particular at least approximately 1,9.
  • the first chamber has a first volume and the second chamber has a second volume.
  • the quotient of the first volume and the second volume is in a range from 1,8, inclusive, to 2,8, inclusive, preferably in a range from 2,1, inclusive, to 2,5, inclusive, and is in particular at least approximately 2,3.
  • the base foil only and not the lid foil is deep drawn to form the first chamber and the second chamber.
  • the major part of the camber volume is provided by the base foil with a significant chamber depth to one side only. This adds to the effect that upon flexion load adjacent chamber walls are pressed together in order to prevent or at least minimize bending deflection of the whole product.
  • arrangements for deep drawing one foil only have to be provided, which reduces machine and manufacturing costs.
  • the unformed lid foil does not have to meet special forming requirements and can therefore be chosen by less restrictive requirements.
  • the base foil and/or the lid foil have a thickness being in a range from 50 ⁇ m, inclusive, to 100 ⁇ m, inclusive, preferably in a range from 60 ⁇ m, inclusive, to 90 ⁇ m, inclusive, and being in particular at least approximately 76 ⁇ m.
  • the foil thickness in said ranges is quite small and does not provide technically relevant bending stiffness, the completed product itself has a sufficient form stability and fulfils all requirements with respect to tightness both for powder and liquid fillings.
  • Fig. 1 shows a perspective top view of an example embodiment of an inventive cleaning agent product.
  • the cleaning agent product comprises a water soluble pouch 10, which is made of a water soluble base foil 5 and a water soluble lid foil 6, the latter one being shown in Fig. 6 .
  • the cleaning agent product has a generally circular shape. Within its circular shape, the base foil 5 is deep drawn under influence of increased temperature and vacuum to form a first chamber 1 and a second chamber 2.
  • the first chamber 1 and the second chamber 2 are separated from each other by a curved separating strip 9.
  • both the first chamber 1 and the second chamber 2 are surrounded by a flat circular arc shaped flange 14, to which the flat separating strip 9 is connected.
  • the flange 14 comprises with distance to its edges a circular arc shaped sealed joint 15, while the separating strip 9 comprises with distance to its edges along its length a sealed joint 11.
  • the sealed joint 11 and the sealed joint 15 are interconnected to each other.
  • the base foil 5 and the lid foil 6 ( Fig. 6 ) are sealed together in a liquid- and powder-tight manner. Thereby, two tightly closed and separated chambers 1, 2 are formed.
  • the first chamber 1 is filled with a first cleaning agent 3, while the second chamber 2 is filled with a second cleaning agent 4, wherein the separating strip 9 and the sealed joints 11, 14 prevent the two cleaning agents 3, 4 to prematurely get in contact to each other and to mix up.
  • the cleaning agents 3, 4 can be identical or different. In particular, they can be in a powder or liquid form. In the shown preferred embodiment, the first cleaning agent 3 is powder, while the second cleaning agent 4 is liquid.

  • the volume of the chambers 1, 2 and formulation of the cleaning agents 3, 4 are chosen and adapted to each other, that the entire cleaning agent product provides an amount of cleaning agents 3, 4 for one single unit dose application.
  • the inventive cleaning agent product may be used for laundry washing or dish washing in particular in a respective machine, for floor cleaning or any other cleaning application, where cleaning water comes into effect.
  • the water soluble pouch 10 dissolves and sets the cleaning agents 3, 4 free in order to provide the correct, desired and readily usable mixture of water and cleaning agents 3, 4.
  • Fig. 2 shows a perspective bottom view of the cleaning agent product according to Fig. 1 . From both Figs. 1 and 2 it can be seen, that the first chamber 1 is approximately kidney-shaped, while the second chamber 2 matches the convex side of the first chamber 1 kidney-shape, while leaving the separating strip 9 in between, and while maintaining the surrounding flange 14 with an approximately constant width.
  • Fig. 3 shows a top view of the cleaning agent product according to Figs. 1 and 2 in a production state, when the base foil 5 is already deep drawn to form the first chamber 1 and the second chamber 2, however without being filled.
