Background to the invention Many consumers do not want to come into contact with detergent ingredients commonly used and found in detergent products, during the washing process. The laundry detergent industry has been trying to prevent or minimize the contact between detergent ingredients and the consumer. For example, the detergent industry developed detergent tablets which minimized the generation of detergent ingredients in the form of dust when handled by a consumer during the washing process. However, these detergent tablets still produce dust when handled by consumers during the washing process. Thus, there is still a need to provide a detergent product which can be used by consumers wherein the contact between the detergent ingredients therein and the consumer is prevented or further minimized.

Attempts have been made to solve this problem by enclosing the detergent ingredients with a film, to form a detergent pouch. These pouches have been further developed by the laundry industry to improve their water-solubility profile and cleaning performance.

In addition, consumers like the benefits of having unit dose detergent products, for example detergent tablets and detergent pouches. Many consumers find unit dose detergent products easier and quicker to use during the washing process. For example, by using unit dose detergent products, the amount of detergent to be used during the washing process is already pre-selected for the consumer, negating the need for the consumer to determine, and weight out, the desired amount of detergent product which can be a difficult and time consuming procedure.

The film used to make detergent pouches is typically expensive. Current processes for manufacturing detergent pouches are not very efficient and produce a large amount of film scrap. To provide detergent pouches which the consumer can afford to purchase, there is a need to develop a process for preparing these pouches which is more efficient, and produces less film scrap The present invention provides a process for preparing pouches which minimizes the amount of film scrap during the production of pouches. This process results in less wastage of film and provides an efficient, cost effective means of producing pouches.

Summary of the invention The present invention provides a process for preparing water-soluble pouches from at least one sheet of water-soluble film, comprising the step of shaping pouches from said water-soluble film in a series of moulds, wherein said moulds are positioned in an interlocking manner.

Leakage of ingredients from the pouch, and ruptures to the film of the pouch are more likely to occur at the corners of the pouch. The pouches prepared by the process herein, are more structurally stable and less likely to rupture or leak ingredients, if the moulds comprise few corners having acute angles. Preferably, the moulds comprise less than two corners having an internal angle of 90°, more preferably the moulds comprise less than two corners having an internal angle of 90° or less, even more preferably the moulds comprise no corners having an internal angle of 90° or less.

This is to minimize the variation of stretch introduced to a film which is pulled flush to the inner surface of the mould. The sides of the mould, which dictate the shape of the mould are preferably a series of straight edges.

The moulds are typically of a size having the largest cross-sectional distance across the face of the mould being from lcm to 50cm, preferably from 2cm to 10cm.

Water-soluble film The water-soluble film, herein referred to as"film", typically the film is water-dispersible and has a dispersibility of at least 50%, preferably at least 75% or even at least 95%, as measured by the gravimetric method set out hereinafter, using a glass-filter with a maximum pore size of 50 microns.

More preferably the film is water-soluble and has a solubility of at least 50%, preferably at least 75% or even at least 95%, as measured by the gravimetric method set out hereinafter, using a glass-filter with a maximum pore size of 20 microns, namely: Gravimetric method for determining water-solubility or water-dispersibility of the film: 50 grams 0. 1 gram of film is added in a 400 ml beaker, whereof the weight has been determined, and 245ml lml of distilled water is added. This is stirred vigorously on magnetic stirrer set at 600 rpm, for 30 minutes. Then, the mixture is filtered through a folded qualitative sintered-glass filter with the pore sizes as defined above (max. 20 or 50 micron). The water is dried off from the collected filtrate by any conventional method, and the weight of the remaining polymer is determined (which is the dissolved or dispersed fraction). Then, the % solubility or dispersibility can be calculated.

The pouch is made from a water-soluble film. Preferred water-soluble films are polymeric materials, preferably polymers which are formed into a film or sheet. The material in the form of a film can for example be obtained by casting, blow-moulding, extrusion or blow extrusion of the polymer material, as known in the art.

Preferred polymers, copolymers, or derivatives thereof, are selected from polyvinyl alcohols, polyvinyl pyrrolidone, polyalkylene oxides, acrylamide, acrylic acid, cellulose, cellulose ethers, cellulose esters, cellulose amides, polyvinyl acetates, polycarboxylic acids and salts, polyaminoacids or peptides, polyamides, polyacrylamide, copolymers of maleic/acrylic acids, polysaccharides including starch and gelatine, natural gums such as xanthum and carragum.

More preferably the polymer is selected from polyacrylates and water-soluble acrylate copolymers, methylcellulose, carboxymethylcellulose sodium, dextrin, ethylcellulose, hydroxyethyl cellulose, hydroxypropyl methylcellulose, maltodextrin, polymethacrylates, most preferably polyvinyl alcohols, polyvinyl alcohol copolymers and hydroxypropyl methyl cellulose (HPMC).

The polymer can have any weight average molecular weight, preferably from about 1000 to 1,000,000, or even form 10,000 to 300,000 or even form 15,000 to 200,000 or even form 20,000 to 150,000.

Mixtures of polymers can also be used. This may in particular be beneficial to control the mechanical and/or dissolution properties of the film, depending on the application thereof and the required needs. For example, it may be preferred that a mixture of polymers is present in the film, whereby one polymer material has a higher water-solubility than another polymer material, and/or one polymer material has a higher mechanical strength than another polymer material. It may be preferred that a mixture of polymers is used, having different weight average molecular weights, for example a mixture of PVA or a copolymer thereof of a weight average molecular weight of 10,000- 40,000, preferably around 20,000, and of PVA or copolymer thereof, with a weight average molecular weight of about 100,000 to 300,000, preferably around 150,000.

Also useful are polymer blend compositions, for example comprising hydrolytically degradable and water-soluble polymer blend such as polylactide and polyvinyl alcohol, achieved by the mixing of polylactide and polyvinyl alcohol, typically comprising 1-35% by weight polylactide and approximately from 65% to 99% by weight polyvinyl alcohol, if the material is to be water-dispersible, or water-soluble.

It may be preferred that the polymer present in the film is from 60% to 98% hydrolysed, preferably 80% to 90%, to improve the dissolution of the material.

Suitable examples of commercially available water-soluble films include polyvinyl alcohol and partially hydrolysed polyvinyl acetate, alginates, cellulose ethers such as carboxymethylcellulose and methylcellulose, polyethylene oxide, polyacrylates and combinations thereof. Most preferred are films which comprises PVA polymers and have similar properties to films that are known under the trade reference M8630, as sold by Chris-Craft Industrial Products of Gary, Indiana, US. Other preferred films suitable for use herein have similar properties to films that are known under the trade reference PT film or the K-series of films supplied by Aicello, or VF-HP film supplied by Kuraray.

The film herein may comprise other additive ingredients than the polymer or polymer material. For example, it may be beneficial to add plasticisers, for example glycerol, ethylene glycol, diethyleneglycol, propylene glycol, sorbitol and mixtures thereof, additional water, disintegrating aids. It may be useful when the pouched composition is a detergent composition, that the pouch or compartment material itself comprises a detergent additive to be delivered to the wash water, for example organic polymeric soil release agents, dispersants, dye transfer inhibitors.

Process The process for preparing water-soluble pouches, herein referred to as"the process" comprises the step of shaping pouches from said water-soluble film in a series of moulds, wherein said moulds are positioned in an interlocking manner.

By shaping, it is typically meant that the water soluble film is placed onto and into the moulds, for example, the film may be vacuum pulled into the moulds, so that said film is flush with the inner walls of the moulds. This is commonly known as vacuum forming.

Another preferred method is thermo-forming to get the film to adopt the shape of the mould.

Thermo-forming typically involves the step of formation of an open pouch in a mould under application of heat, which allows the film used to make the pouches to take on the shape of the moulds.

Vacuum-forming typically involves the step of applying a (partial) vacuum (reduced pressure) on a mould which sucks the film into the mould and ensures the film adopts the shape of the mould. The pouch forming process may also be done by first heating the film and then applying reduced pressure, e. g. (partial) vacuum.

The film is typically sealed by any sealing means. For example, by heat sealing, wet sealing or by pressure sealing. In a preferred embodiment, a sealing source is contacted to the film and heat or pressure is applied to the film, and the film is sealed. The sealing source may be a solid object, for example a metal, plastic or wood object. If heat is applied to the film during the sealing process, then said sealing source is typically heated to a temperature of from 40°C to 200°C. If pressure is applied to the film during the sealing process, then the sealing source typically applies a pressure of from 1x104 Nom~2 to lx106 Nm~2, to the film.

The same piece of film may be folded, and sealed to form pouches. Typically more than piece of film is used in the process herein. For example, a first piece of the water soluble film may be vacuum pulled into the moulds so that said film is flush with the inner walls of the moulds. A second piece of water-soluble film may be positioned such that it at least partially overlaps, preferably completely overlaps, with the first piece of film. The first piece of film and second piece of film are sealed together. The first piece of film and second piece of film can be the same type of film or can be different types of film.

If the pouches obtained from the process herein contain a composition, then in a preferred embodiment of the present invention, a first piece of the water soluble film may be vacuum pulled into the moulds so that said film is flush with the inner walls of the moulds. A composition may be poured into the moulds, and a second water-soluble film may be placed over the moulds with the composition and the first piece of film and second piece of film are sealed together to form pouches, typically in such a manner as to at least partially enclose, preferably completely enclose, the composition.

Preferably the first film is stretched, as defined hereinafter. Typically, the second film is not as stretched as the first film.

Preferably, the first film has an unstretched thickness of from 50 micrometers to 200 micrometers, preferably from 60 micrometers, or from 70 micrometers, and preferably to 150 micrometers, or to 100 micrometers, or to 90 micrometers, or to 80 micrometers.

Preferably the second film has an unstretched thickness of from 5 micrometers to 40 micrometers, preferably from 10 micrometers, or from 20 micrometers, or from 30 micrometers.

It may be preferred that the film, and preferably the pouch as a whole, is stretched during formation of the pouch, such that the resulting pouch is at least partially stretched. This is to reduce the amount of film required to enclose the volume space of the pouch.

When the film is stretched the film thickness decreases. The degree of stretching indicates the amount of stretching of the film by the reduction in the thickness of the film. For example, if by stretching the film, the thickness of the film is exactly halved then the stretch degree of the stretched film is 100%. Also, if the film is stretched so that the film thickness of the stretched film is exactly a quarter of the thickness of the unstretched film then the stretch degree is exactly 200%. Typically and preferably, the thickness and hence the degree of stretching is non-uniform over the pouch, due to the formation and closing process. For example, when a water-soluble film is positioned in a mould and an indent is formed by vacuum forming (and then filled with the components of a composition and then closed), the part of the film in the bottom of the mould, furthest removed from the points of closing will be stretched more than in the top part. Preferably, the film which is furthest away from the opening, e. g. the film in the bottom of the mould, will be stretched more and be thinner than the film closest by the opening, e. g. at the top part of the mould.

Another advantage of stretching the film, is that the stretching action, when forming the shape of the pouch and/or when closing the pouch, stretches the pouch non-uniformly, which results in a pouch which has a non-uniform thickness. This allows control of the dissolution of water-soluble pouches herein, and for example, sequential release of the components of a detergent composition enclosed by the pouch to the water.

Preferably, the pouch is stretched such that the thickness variation in the pouch formed of the stretched water-soluble film is from 10 to 1000%, preferably 20% to 600%, or even 40% to 500% or even 60% to 400%. This can be measured by any method, for example by use of an appropriate micrometer. Preferably the pouch is made from a water-soluble film that is stretched, said film has a stretch degree of from 40% to 500%, preferably from 40% to 200%.

The process herein may be used to prepare pouches which have an internal volume that is divided into more than one compartment, typically known as a multi-compartment pouches. In this preferred process, the film is folded at least twice, or at least three pieces of film are used, or at least two pieces of film are used wherein at least one piece of film is folded at least once. The third piece of film, or a folded piece of film, creates a barrier layer that, when the pouch is sealed, divides the internal volume of said pouch into at least two compartments.

The process herein can be used to prepare water-soluble multi-compartment pouches by, fitting a first piece of the water soluble film into a series of moulds, for example the first piece of film may be vacuum pulled into the moulds so that said film is flush with the inner walls of the moulds. A composition is typically poured into the moulds. A pre- sealed compartment made of a water-soluble film can then be placed over the moulds containing the composition. These pre-sealed compartments and said first piece of film may be sealed together to form multi-compartment pouches, for example, dual- compartment pouches.

Pouch obtained therefrom The pouches obtained from the process herein are water-soluble. Water-soluble typically being determined by the gravimetric method described hereinbefore.

The pouch is typically a closed structure, made of a water-soluble film described herein, typically enclosing a volume space which preferably comprises a composition. Said composition is described in more detail hereinafter. The is preferably suitable to hold a composition, e. g. without allowing the release of the composition from the pouch prior to contact of the pouch to water. The exact execution will depend on for example, the type and amount of the composition in the pouch, the number of compartments in the pouch, the characteristics required from the pouch to hold, protect and deliver or release the compositions.

The volume space of the pouch can be divided into more than one compartment. Pouches having a volume space which is divided into more than one compartment are herein referred to as multi-compartment pouches. If these multi-compartment pouches contain a composition, then different compartments may contain different ingredients of the composition. For example, incompatible ingredients may be contained in different compartments.

The pouches may be of such a size that it conveniently contains either a unit dose amount of the composition herein, suitable for the required operation, for example one wash, or only a partial dose, to allow the consumer greater flexibility to vary the amount used, for example depending on the size and/or degree of soiling of the wash load. The shape and size of the pouch is typically determined, at least to some extent, by the shape and size of the mould.

A lmm thick layer of rubber is present around the edge of each mould. The moulds have some holes in the mould material to allow a vacuum to be applied. The moulds are positioned in three rows, each row having four moulds. The moulds are positioned in an interlocking manner such that the edges of the adjoining moulds touch.

A vacuum is applied to pull a single piece of film into the moulds so that the film is flush with the inner surface of the moulds. Solid detergent composition is poured into each mould so that the moulds are filled between 95% to 100%.

Next, another sheet of water-soluble film (Chris-Craft M-8630 film) is placed over the top of the moulds containing the solid composition, and is sealed to the first layer of film by applying a piece of flat metal of a size to completely cover the whole series of moulds, and heating that metal under moderate pressure onto the pieces of rubber at the edges of the moulds to heat-seal the two pieces of film together. The piece of metal is typically heated to a temperature of 140-146°C and applied for up to 5 seconds.

The film is then cut to produce individual single pouches.
