Description

DESCRIPTION

Package containing water-soluble capsules

This invention relates to a product comprising bulk quantities of water-soluble machine dishwashing or laundry capsules made of water-soluble film contained in a biodegradable container.

US 2021/047072 (Ng Pak Leung) discloses a consumer product including a package and at least one water soluble unit dose item.

WO 02/20361 discloses an article of manufacture or a package for containing and dispensing unitized doses of a laundry additive in article form. The package comprises a plurality of laundry additive items, means for preventing exposure of the laundry items to moisture prior to dispensing or use, and a container having a compartment and closure for enclosing the plurality. of items in the container. The container can be a pail, a tray, a jar, a bottle, a bag, a box, or some combination thereof, and will preferably be made of polymeric materials. Optionally, the container may have dividing means to subdivide the container compartment into sub-compartments, such that the container can house several different additives in separate compartments. Optionally, but preferably, the container closure will have child resistant features, as well as a window or other means to view the contents of the container when the closure is in the closed position. The means of preventing exposure of the items to moisture may simply be a seal on the container closure or may comprise a separate seal for each item of laundry additive. The individual item seals will preferably be a tray with a recess formed therein to receive the laundry additive item and a polymeric film adhered to the tray above the recess to seal the item inside.

Document WO 2016/198978 discloses a child-resistant container comprising: a casing made of sheet material that defines an interior volume and presents a passage opening delimited by a free edge, a closure system made of shaped sheet material To define the closing and opening conditions of the casing, the closure system comprises a tongue that has a closing portion movable with respect to the free edge of the casing. The container includes a safety device made of sheet material having: a first hook portion carried by the tongue, a second hook portion coupled to the housing. The first and second latching portions are configured to stably engage each other in the closed state of the latch system and to define a secure state: the first and second latching portions, in the secure state, are configured to prevent the locking system from changing from the locked to the unlocked state.

Water soluble capsules are very convenient, however certain compositions are required to have imprint on them to indicate directions and other information to the consumer.

It is also desirable to limit access to the capsules, especially with regard to children, by incorporating child resistant features into the packaging. Today's capsules are generally packaged in pails or plastic bags. This material is impervious to water and the contained formulas. Currently, rigid packaging can be recycled, but there is an environmental need to reduce the use of plastics. Compostable or biodegradable material offers environmental advantages, however, due to its very nature (it is the tendency to biodegrade) the use of these materials is problematic. If the capsules leak, for example due to an imperfect seal, the packaging may be weakened by premature degradation of the biodegradable material if it comes into direct contact with the filtered formulation. The mechanical properties of the container are compromised. Under the weight of a large number of bulk capsules, and the likely leakage of moisture from the capsules, the integrity of any child resistant closure may be compromised. Therefore, the package may be more easily accessible to children, which is undesirable.

Furthermore, while plastic containers are often hermetically sealed and therefore have very low water vapor transmission rates, fiber or pulp containers are likely to have high water transmission properties. This means that the probability of water ingress and/or egress is much higher and therefore there is an impact on the physical performance of unit dose products within a fiber or pulp container. A particular feature is that unit dosed products containing detergent compositions with 5 to 15% water tend to stick to the inner surface of such packages during storage. This adhesion is due to the fact that the outer surface is negatively affected by the transmission of water when stored in a paper container. When printing inside we have verified that this feature is significantly reduced. The fact that the location of the print is decisive for the performance of a product dosed per unit in a biodegradable package, such as pulp or fiber, is unexpected but welcome.

Accordingly, and in a first aspect, a container for unit dose detergent sachets is provided, said container comprising a telescopically engaging lid and a base, wherein said base and top can cooperate to form a closed container that is openable for access to the contents by pulling, said lid and base comprising a plurality of unit dose detergent sachets, and wherein said unit dose detergent sachets comprise fragrance.

Surprisingly, we have found that it is possible to offer a more commercially attractive product by using a lid and base that telescopically interlock to form a package containing scented detergent sachets. When the consumer separates the lid and the base, the air pressures generated cause a pressure drop inside the container and forces air from outside the container into the container. This pressure shock also releases more fragrance into the headspace between the bags and the container. When the container is closed again, the opposite effect causes a sudden increase in pressure inside the container and forces the fragrance cloud out of the container. As a result, the consumer is bathed in a cloud of pleasant fragrance.

The effect is particularly suitable for packaging comprising biodegradable materials such as cellulose-based materials, eg paper, pulp and cardboard, where the fragrance is conveniently contained without excessive premature release.

As used in this specification, including the claims, the following terms are defined:

The articles "a" and "an" , when used in a claim, are understood as one or more of the claimed or described elements.

"environmentally active" in the context of enzyme compositions, means that it is active at a temperature not higher than 40 °C, preferably not higher than 30 °C, more preferably not higher than 25°C, more preferably not higher than 15°C, but always higher than 1 degree Celcius, and "active" means effective in achieving stain removal, also defined herein.

"Child-resistant closure mechanism" means any mechanism by which access to water-soluble capsules is reduced so that infants and children cannot easily remove them. This preferably comprises any suitable arrangement that requires individuals to perform multiple cognitive and manipulative steps to open, so as to prevent a child from inadvertently accessing the capsules.

"Compostable" means a material that meets all three of the following requirements (1) is capable of being processed in a solid waste composting facility; (2) if it is processed like this, it will end up in the final compost; and (3) if the compost is used on the soil, the material will eventually biodegrade in the soil.

"Enzyme" includes enzyme variants (produced, for example, by recombinant techniques). Examples of such enzyme variants are disclosed, for example, in EP 251,446 (Genencor), WO 91/00345 (Novo Nordisk), EP 525,610 (Solvay) and WO 94/02618 (Gist-Brocades NV).

"Essentially free of a component" means that no amount of that component is deliberately incorporated into the composition.

"Film" refers to a material that is soluble in water and may be a material in the form of a sheet. The length and width of the material can greatly exceed the thickness of the material, although the film can be of any thickness.

"Renewable" means a material that can be produced or is derivable from a natural source that is periodically (for example, annually or perennially) replenished through the actions of plants in terrestrial, aquatic, or oceanic ecosystems ( eg agricultural crops, edible and inedible herbs, forest products, algae), or micro-organisms (eg bacteria, fungi or yeast).

"Renewable Resource" means a natural resource that can be replenished within 100 years. The resource can be replenished naturally or through agricultural techniques. Renewable resources include plants, animals, fish, bacteria, fungi, and forest products. They can be natural, hybrid or genetically modified organisms.

By "thermoforming" is meant a process in which the film is deformed by means of heat and, in particular, can consist of the following: a first sheet of film is subjected to a molding process to form a gap in the film, for example, by forming a hole in the film. Preferably this involves heating prior to deformation. The deformation step is preferably performed by placing the film over a cavity and applying a vacuum or underpressure within the cavity (to hold the film in the cavity). The gaps can then be filled in. The process can then include superimposing a second sheet over the filled voids and sealing it to the first sheet around the edges of the voids to form a flat band of sealing, thus forming a capsule that can be a dose product. unitary. The second sheet can be thermoformed during manufacture. Alternatively, the second film may not be thermoformed during manufacture. Preferably, the first water-soluble film is thermoformed during manufacture of the single-dose article and the second water-soluble film is not thermoformed during manufacture of the single-dose article.

"Unit dose" means an amount of composition suitable for treating a laundry load, such as about 0.05 g to about 100 g, or 10 g to about 60 g, or about 20 g to about 40 g.

All polymer molecular weights are determined on a number average molecular weight basis, unless specifically stated otherwise.

Numerical ranges expressed in the format "x to y" are understood to include x and y. When multiple preferred ranges are described in the "x to y" format for a specific feature, it is understood that all ranges combining the different endpoints are also contemplated. By specifying any range of values or quantities, any particular higher value or quantity can be associated with any particular lower value or quantity.

The packaging material

The container preferably comprises a biodegradable material. The biodegradable material may comprise a biodegradable polymer. The package may comprise a fully biodegradable material, such that the entire package can be completely broken down from a substance by microorganisms such as bacteria, fungi, yeasts, and algae; ambient heat, humidity, or other environmental factors to carbon dioxide, water biomass, and inorganic material. Preferably, between 90 and 99.9% by weight of the package, and more preferably between 96 and 99.9% by weight, is made up of pulp or fiber materials, such as paper, cardboard or cardboard. The rest comprise barrier materials and/or information labels. However, it is preferred that any label also comprise biodegradable materials such as those described herein, preferably paper or other fiber or pulp-based material.

If desired, the degree of biodegradability can be determined according to, for example, ASTM 5338.92 test procedure.

Suitable biodegradable materials include paper, cardboard or cardboard made from cellulose or derivatives; and may optionally comprise lignin or derivatives; biodegradable plastics, such as bioplastics that are preferentially oxo-biodegradable plastics in which biodegradation is the result of oxidative and cellular phenomena, either simultaneously or successively (as opposed to oxo-degradation, which is degradation resulting from "oxidative splitting of macromolecules", so the plastic fragments but does not biodegrade, except over a very long time). The material can also be compostable.

The biodegradable material comprises a biopolymer such as polylactic acid (PLA), which can come from, for example, corn starch, cassava, sugar cane, etc.; polyhydroxyalkanoate (PHA), which includes poly-3-hydroxybutyrate (PHB or PH3B), polyhydroxyvalerate (PHV), and polyhexanoate (PHH). A PHA copolymer called poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV); biodegradable polyesters, eg polycaprolactone (PCL), polybutylene succinate (PBS), polyvinylalcohol (PVA); polybutylene adipate-terephthalate (PBAT); Cellulose-based materials, eg ethyl cellulose, polypropylene glycol. eg ethyl cellulose, cellulose acetate (true) cellophane (made from wood, cotton or hemp); starch or starch-based materials (from potato, rice, corn, etc.); sugarcane bagasse, and any combination or mixture thereof. For example, the PCL can be mixed with starch to improve the biodegradability of the PCL.

The biodegradable material can comprise any biodegradable polyolefin.

Petroleum-based biodegradable plastics include: polyglycolic acid (PGA), a thermoplastic polymer and an aliphatic polyester; polybutylene succinate (PBS), which is a thermoplastic polymer resin that has properties comparable to those of propylene; polycaprolactone (PCL), since it has hydrolyzable ester bonds that offer biodegradable properties. Firmicutes and proteobacteria have been shown to degrade PCL. Penicillium sp. can degrade high-density PCL; although not as rapidly as Aspergillus sp. strain ST-01. thermotolerant. Clostridium species can degrade PCL under anaerobic conditions; polybutylene adipate terephthalate (PBAT) which is a biodegradable random copolymer.

The most preferred biodegradable materials are paper, cardboard or cellulose cardboard or derivatives.

Preferably, the biodegradable material is biobased according to 14C or the radiocarbon process (EU: EN 16640 or CEN/TS 16137, International: ISO 16620-2, USA: ASTM 6866).

Preferably, the biodegradable material is made from a renewable resource.

The packaging material may include an outer layer that provides additional protection or shine (for biodegradable materials with a matte finish, such as cardboard). This layer preferably comprises a biodegradable polymer coating, varnish or film. Preferably, the outer layer comprises any of the biopolymers described above. Preferably, the outer layer is present on at least some or all of the internal surfaces of the container.

The term fibrous or pulp material specifically includes paper or paperboard. Preferably, the fibrous or pulp material is in sheet form and is formed as a blank that is folded to form a closable container. The closable package can be made up of a single blank or it can contain several pieces.

The material that can be used to manufacture the container can have a grammage of 100 and 500 g/m2, preferably between 200 and 400 g/m2. The sheet paper material used to manufacture the container may, in a variant embodiment thereof, be covered, at least in part of the first and/or second predominant development surface, by a coating, for example a film. , whose objective is to balance the transfer of water between the interior and the exterior of the container with the protection against leaks. Advantageously, but not limitingly, the coating can comprise an extrusion coating on one or both sides (inner and/or outer side) of the paper material that defines the container, with values that can range, for example, between 10 and 50 microns of investment material. The plastic lining material can be selected, for example, from the following materials LDPE, HDPE, PP, PE.

Preferred barrier materials include polymeric materials selected from polylactic acid, polyhydroxyalkanoate, a polyester, polybutylene adipate terephthalate, a cellulose-based material, a starch-based material, a sugarcane-based material, and mixtures thereof.

In a preferred embodiment the biodegradable material comprises at least two layers, more preferably at least three.

The biodegradable material preferably comprises a bleached layer and said bleached layer comprises an outer layer of the biodegradable material. By outer layer it is meant that the bleached layer is physically the outermost. A second layer comprises an unbleached layer that is also outer but opposite to the bleached layer. Thus, the biodegradable material preferably comprises a bleached and an unbleached layer on opposite sides. Between the bleached and unbleached layer there is preferably a filler layer composed of post-use recycled material and preferably also paper-based.

Cellulose fiber length

Preferably, the biodegradable material used in the present invention is paper-based. By paper base is meant that it is derived from natural cellulose-containing sources, such as trees. The physical properties of the paper, or pulp-based product, are highly dependent on the nature of the cellulose fibers that are separated from the lignin during processing. This can be determined by the source of the cellulose, ie what kind of tree the original source is, and also what processing has been carried out. There is a common tendency to characterize paper as recycled or virgin, not recycled, however this is misleading as it is the physical nature of the cellulose fiber that is key to its performance in the context of this invention. For example, hardwood fibers are usually good for softness and formation and have short grains. Typical sources of hardwood are eucalyptus, birch, maple, beech, and oak. By contrast, softwood fibers are good for strength and stiffness and include those from pine, fir, and spruce.

Therefore, when the at least one layer of biodegradable material is paper based, it is preferred that the weight average fiber length of the cellulose in the paper is at least 2 mm, more preferably 3 to 5 mm. .

The length of the cellulose fiber is characterized according to the test known by the TAPPI (Technical Association of the Pulp and Paper Industry) as T 271 om-18, which is a procedure designed to measure the length of the pulp fiber and the paper by an automated optical analyzer using polarized light. The test is an approved American National Standard (ANSI).

Where the package comprises cooperating base and lid elements, it is preferred that the base contain a layer of paper with a weight average fiber length of at least 2 mm, more preferably 3 to 5 mm. Surprisingly, we have found that this longer fiber length provides better performance when the package is designed to store liquid detergent pods, especially in the context of containing water in the event of a leak. This is especially important where child safety features are required in the package design, as poor water containment can lead to package weakness and therefore easier access to the contents.

When the package comprises a separate lid part, it is preferred that the lid is made of paper with a weight average cellulose fiber length of 1 to 5 mm. In a preferred embodiment, the cover comprises from 80%, more preferably from 95% by weight, of the cover paper with a weight average length of cellulose fiber of 1 to 5 mm.

In a preferred embodiment, the base comprises from 80%, more preferably from 95% by weight, of the base paper with a weight average cellulose fiber length of at least 2 mm.

Impression

The product dosed per unit is printed to provide useful information to the consumer. Printing is essentially done on the inside of the capsule or the product once it is formed. Typically, printing is carried out on a roll of film prior to manufacturing the product and in such a way that the printed surface is the surface that faces the detergent composition when the final product is formed.

The printing area can cover all or part of the film. The printing zone can be of a single color or of several, even three. The print zone can include white, black and red colors. The print zone may include pigments, dyes, bluing agents, or mixtures thereof. The print may be present as a layer on the surface of the film or may at least partly penetrate the film. The printing area may be present on the outside of the single dose article, in addition to the inside surface of the film, ie, in contact with the liquid laundry detergent composition.

Preferably, the film comprises a phthalocyanine-based pigment. Said pigment is used for printing on the film. A preferred pigment is SpectraY® F UVDB354, commercially available from Sun Chemical, which is a phthalocyanine-based pigment. It is called CAS 147-14-8.

The single dose article may be comprised of at least two films, or even three films, where the films are sealed together. The print area may be present on one film, or on more than one, eg two or even three.

The print area can be achieved by standard techniques such as flexo printing or ink jet printing. Preferably, the print area is achieved by flexographic printing, in which a film is printed which is then molded to form a single dose article.

The package contains a plurality of water-soluble capsules, each of which comprises a detergent composition within a sealed compartment that is preferably filled to at least 60% of the volume of the compartment.

Preferably, the package comprises 10 or more such unit dosage products and a closure.

With this arrangement, water soluble capsules with yield levels of substrate treatment fluid can be filled at high speed and packaged in large quantities to reduce manufacturing costs, but can be packaged using biodegradable materials and still minimize harmful leaching effects. the capsules. This is surprising considering the similarity in the compositions that they form the capsule film and also the polymers used in the biodegradable packaging.

The selected viscosity range ensures that fill times do not slow manufacturing times in such a way that capsules become too expensive. At the same time, the Applicants have discovered that if the liquid is thickened to a viscosity as specified in the first aspect of the invention, splashing in the sealing areas of the capsules is minimized and ripple formation is also minimized (in the formulation) which could also affect the integrity of the seal, since the capsules fill at a high speed.

The recipient

The container preferably has a minimum compression resistance of 300N. The thickness (or gauge) of the material will be chosen to provide the necessary structural rigidity to the package.

The container may comprise any suitable rigid structure, such as a pail or carton, a tubular structure, or a bottle. However, preferred containers will be formed from a blank that will be made into a container. Preferably, the container will comprise a base, pairs of opposing walls and a closable lid. Preferably, the lid is integrated into the base or is formed as a separate component.

The walls of these structures can be foamed or molded. It may comprise laminated structures (eg built in layers). It may comprise fibrous material, such as fibers/pulp, which is glued, compressed and/or enclosed in rigid walls. Ridges can be incorporated, for example, into corrugated cardboard. In the case of cardboard, the grammage is preferably at least 200 gsm (grams per square meter), preferably at least 225 gsm.

The structure can be folded between an upright structure to provide a functional receptacle and a flattened structure to aid transport and ease of subsequent disposal, so that multiple packs could be flattened and stacked ready for transport to a biodegradation site.

The biodegradable package may comprise a combination of a fibrous and/or pulp material and a polymeric material. An example may be a material comprising one or more layers of fiber and/or pulp in combination with one or more polymeric materials (all materials being biodegradable). There may be one or more layers of fiber and/or pulp sandwiched between layers of polymeric material. The material can be virgin or recycled.

As regards the dimensions, it is preferred that the container has a top surface which, when closed, has a width of between 9 and 15 cm. This width is averaged over the entire upper surface. This width is preferred because biodegradable packaging tends to flex more easily than more rigid plastic packaging and we have found that this dimension correlates with optimal consumer behavior in opening the packaging to access the contents using appropriate force and in this way without damaging the biodegradable container or the content it includes. This is the case, in particular, when the child-resistant closure requires the simultaneous pressing of unlocking zones on opposite side walls. These opposing pressures can damage the contents of the container by pressing on the capsules that are already under water transmission stress.

Where the container comprises a separate lid and base, it is preferred that the lid comprises a top sheet and dependent opposite pairs of walls, so as to resemble the five faces of a cube. Likewise, it is preferred that the base comprises a bottom sheet and dependent opposite pairs of walls, so that it also resembles the five faces of a cube.

Thus, the lid and the base cooperate to form a closed container with the pairs of opposite walls for each of the lid and the base providing double protection from the outside when the lid and the base telescopically cooperate. Preferably, the lid provides the outermost surface when the base and lid telescope together to close the container.

Preferably, the cap comprises a bleached layer in the outermost layer and an unbleached layer in the innermost layer. In this configuration, the bleached layer presents the outermost surface of the container for the five sides that make up the lid. Preferably, this outermost layer comprises printed parts.

Preferably, the bleached layer also comprises a barrier material as described below. More preferably, the innermost surface comprises an unbleached layer, and more preferably is not treated with a barrier material.

Preferably, the base comprises a bleached layer in the innermost layer and an unbleached layer in the outermost layer. In such a configuration, the bleached layer presents the innermost surface of the container on the five sides that make up the base. Said innermost layer is physically in contact with at least some of the products dispensed from the washing unit.

Preferably, the bleached layer also comprises a barrier material as described below. More preferably, the innermost surface of the base comprises an unbleached layer, and more preferably is also treated with a barrier material.

Preferably, the lid comprises at least one opening through which air from outside the container can enter the container during the separation of the lid and the base, and where fragrance from the inside of the container can escape from the container. Said opening does not form part of any general opening by which the base and the lid are separated, but is arranged in a side wall depending on a top surface of the lid.

The opening is preferably closer to the upper surface of the lid in the side wall than to the bottom edges of the side wall. This allows more air to enter the headspace of the canister more quickly and therefore generates faster airflow into the canister when the lid is removed from the base. In addition, more air is expelled from the space between the base and the lid when the lid and base telescope together when the container is closed. In the same way, more air is forced out of the interior of the container through the openings when they are closed. The result is a greater expulsion of the fragrance cloud from the container when opening and closing it. Preferably, the lid has a top sheet and two pairs of opposite walls attached thereto, and at least one of the pairs of opposite side walls comprises a pair of openings.

The lid and the base are telescopically coupled. This means that the dimensions of each are such that one slides into the other when the two are pulled apart or pressed together. each. Preferably, the lid slides off the outside of the base when the two are attached.

Preferably, the base and the lid comprise side walls that extend a substantially similar distance, so that when closed, the lid forms the top and sides of the container, the base being visible only at its bottom, and the Base sidewalls are inside the lid sidewalls, so they are not visible for the most part.

Preferably, the side walls of the base extend beyond the distance between the opening(s) in the side wall(s) of the lid, such that when in a closed configuration the side wall(s) of the base close the opening(s) of the side walls of the lid.

More preferably, the opening is located in such a way that the lid and the base can be partly separated and the opening remains closed by the side wall of the base. This means that the side wall of the base extends past the top of the opening and the distance beyond the top of the opening determines how much the base and lid can be separated before the opening is exposed. appearing above the edge of the lateral wall of the base.

In an alternative embodiment the container comprises a container drawer which is open at the top allowing access to the contents of the container, and which is slidable with an outer case closing access when the drawer is fully nested within the case. In such an embodiment, the box would correspond to the lid described above and the drawer to the base.

barrier materials

The package comprises a barrier material to improve performance.

Barrier materials are preferably used to control moisture and are usually applied to the board surface on one or both sides, depending on the end use.

dispersal barrier

The dispersion is a new barrier option without the traditional coating layers. The surface is finished with water-based dispersion technology. This makes the board resistant to liquids and grease during use, while breaking down in a recycling process just like paper, providing a high yield of recovered fiber when the products are recycled.

Green PE liner

Green PE is a fully renewable alternative to traditional PE (polyethylene) and provides excellent protection against moisture. Green PE is made from renewable plant-based raw material, resulting in a barrier packaging that is 100% renewable as well as recyclable. When converted, it has the same performance as PE and is therefore easy for customers to introduce into production.

PE liner

PE, or polyethylene, is the most widely used barrier coating. Polyolefin barriers, such as LDPE and HDPE polymers, provide excellent moisture protection.

biodegradable lining

Biodegradable liners are custom-made polymers that offer moisture, oxygen and grease barriers, as well as sealing capabilities. Our biodegradable liners are compostable. However, biopolymer-coated paperboard can also be easily recycled, which is often the preferred option at the end of its useful life.

Biopolymers can be produced from natural crops or from fossil raw materials. But the key is that in the end, the biopolymer-coated cardboard decomposes into humus and CO2. If you choose our biopolymer-coated cardboard, you will get a product that is recyclable or can be collected among other compostable waste that goes to industrial composting.

PET lining

The PET provides a barrier and performs other functions. Black or white PET liners that provide heat resistance act as an excellent barrier against grease and have strong WVTR (Water Vapor Transmission Rate) properties.

PP liner

The PP, or polypropylene, liner offers heat resistance for microwave ovens and is also suitable for freezing. Good sealing properties ensure performance in use.

However, it is preferred that the barrier material comprises less than 5% by weight, more preferably less than 1%, and preferably zero PE, PP or PET.

In a preferred embodiment, the barrier comprises a water-based dispersion.

Water-based barrier coatings seal the surface of the substrate and protect the packaging from external and internal influences. The packaging remains attractive and can fulfill its functionality without restrictions. Depending on the product, our barrier coatings offer adequate protection against grease, water, steam, dairy, alcohol, oil or alkalis for the life of the package. Due to their versatility they are used for a wide range of applications. Barrier coatings are available for packaging converters and printers or the paper industry.

Preferably, the base of the container comprises a waterborne dispersion barrier layer.

Preferably, the base barrier material is applied to an interior surface

Preferably, the cap component comprises less than 1 % by weight of the barrier material, more preferably a water-based dispersion barrier.

More preferably, the dispersion barrier component comprises a thermoplastic elastomer (TPE). Said TPE is preferably dispersed in the barrier component.

The advantage of a TPE containing barrier material is that it is dispersed in the barrier component so that layers are not needed. The dispersion is applied in one go.

An alternative barrier component may comprise a multilayer approach. Such barriers include those commercially available from Weilburger under the Senolith® brand. Examples are described in WO 2018/069413. Preferably, they would be applied by digital printing, ink chute damping unit, flexo printing, online-offline coating unit, and web offset, as well as gravure.

Such barrier materials could be applied primarily as a wet coat. The dispersion is preferably an aqueous dispersion, in particular a PTFE dispersion, a perfluoroalkoxy (PFA) polymer dispersion, and/or fluorinated ethylene-propylene (FEP), hexafluoropropylene copolymer.

When a coat is applied wet, a surface film forms which can then be cured. A first layer may have a resin to improve adhesion to a substrate. Examples of suitable resins are, without limitation, polyamideimide, polyphenylene sulfide (PPS), polyether sulfone (PES), polyether ether ketone (PEEK), silicone resin, and/or polysulfone. The proportion of such a resin in a wet composition to be coated, in particular a dispersion, is preferably about 3 to 8 percent by weight of the composition.

The second polymer is applied to the first layer in a liquid. The dispersion may contain other components mentioned herein. The dispersion is preferably an aqueous dispersion, in particular a PTFE dispersion, a perfluoroalkoxy (PFA) polymer dispersion and/or a fluorinated ethylene-propylene (FEP, copolymer of hexafluoropropylene and tetrafluoroethylene) dispersion. The proportion of the second polymer in a wet composition to be coated, in particular a dispersion, is preferably about 40-60 percent by weight. The first coat may be dry, partially dry, or not dry before application of the second coat. In an advantageous variant, the second layer is applied to the first layer while the first layer is still wet, in particular while the first layer is still wet.

Preferably, both the lid and the base comprise multilayer barrier material as described above.

Preferably, the barrier material is applied to the exterior of the lid and/or the base. More preferably, the barrier material is applied to at least 50%, more preferably 70%, especially preferably 90% and most preferably 95% of the outer surface of the lid.

More preferably, the barrier material is applied to at least 50%, more preferably 70%, especially preferably 90% and most preferably 95% of the outer surface of the base.

More preferably, the base comprises barrier material on the outer and inner surfaces.

Adhesive

Adhesives are common in the art, but are preferably a hot melt adhesive, a reactive hot melt adhesive, a thermosetting adhesive, a pressure sensitive adhesive or a contact adhesive. Preferably the adhesive is a hot melt pressure sensitive adhesive. Preferably, the hot melt pressure sensitive adhesive is suitable for adhering and bonding to a variety of package component materials.

total content

Preferably, the barrier material and the adhesive comprise from 0.1 to 5% by weight of the total package plus the adhesive and the barrier material, ie without the single-dose bags. More preferably, the barrier material and adhesive comprise 1 to 3% by weight, and most preferably 1.5 to 2.5% by weight of the total package plus adhesive and barrier material.

Preferably, the barrier material and the adhesive comprise from 0.1 to 5% by weight of the lid plus the adhesive and the barrier material.

The invention includes a child resistant closure mechanism comprising a first locking element on the receptacle and a second locking element present on the closure whereby the elements interlock.

The child resistant closure is obtained by specific structures to secure the closure in place (closing the receptacle) until a specific operation is performed to disengage the closure.

The closures may include caps with respective closure elements that must be aligned in a certain orientation before they are released from the closure elements. closure on the receptacle, or that require the completion of a certain sequence of steps or actions to trigger their release as described below.

The receptacle and closure may each incorporate at least one, and preferably at least two, of these locking elements, and the package is closed by locking multiple pairs of locking elements, each pair comprising a locking element at the closure that interfaces with a locking element of the receptacle. Preferably, each pair of latch elements is operable independently of any other pair of latch elements, such that unlocking one pair does not automatically unlock the other pair. Preferably, at least one pair is spaced apart from another pair at locations on the package so that, for example, they may be located in diagonally opposite positions, for example, on diagonally opposite edges/corners of a generally square/rectangular closure or in diametrically opposite positions on the edge of a circular closure.

Preferably, the or each locking element comprises a part resilient so as to spring into and/or out of a locking engagement with a respective locking element.

Locking elements can be chosen from any projection and corresponding recess, clasps, clips, latches, flaps, straps, hook and loop fasteners, ratchet or tab (threaded) arrangements, slider arrangements, buttons, pull tabs, keys , magnets or other locking components. The locking elements can be arranged, for example, spring-loaded in the locked position (engaged with a respective locking element), so that pressure must be exerted to release them from each other.

The receptacle and the closure may be hinged together or may slide relative to each other and may even be unitary (eg with a live hinge) so that the closure is integral with the receptacle. The invention is especially preferred for this type of arrangement, since the softening of the receptacle can lead to deformation and stresses in the closure.

The specific operation may comprise a double and/or coordinated action on the closure. Preferably, the child-resistant closure is made up of locking elements that require a double and/or coordinated action to open said closure. So by For example, the required action may be a push-turn or push-pull mechanism, as is known to the person skilled in the art. For example, the closure can be opened only when the closure or a part thereof is squeezed (radially) and rotated, or pushed (axially from the container) and rotated. Child resistant closures may consist of grasping or squeezing both sides of the closure and twisting at the same time to remove the closure. The closure may be retained in the receptacle by the respective internal threads which carry pawls or wedge-shaped tabs as locking elements, and prevent the closure from being unscrewed from the neck opening unless the closure and/or neck is removed. flex diametrically whereby the locking elements separate in a radial direction and allow the closure to be unscrewed.

Lock items may require a double and/or coordinated action to unlock. For example, the packaging, for example, push and slide, or push and pull. A removable locking key may be required to lock and/or unlock these interlocking elements.

The package may comprise a sliding mechanism whereby the closure, or a part thereof, slides relative to the receptacle or the receptacle slides within a closure (for example, as a tray package arrangement whereby the capsules are stacked in the tray part) and at least one locking mechanism configured to lock the inner sliding part relative to an outer part of the container is provided. The locking mechanism may be arranged so that pressure is required to release the tray. In some embodiments, the inner sleeve includes a pull tab for removing the inner sleeve from the interior of the outer sleeve.

The blocking elements can be spatially arranged to prevent access by children. For example, at least two pairs may be separated from each other by a distance that corresponds to the average distance between the thumb and the index finger of an adult hand. Only when the two pairs are released simultaneously is it possible to open the lid of the packaging container.

In the case of box constructions, preferably the locking elements are located at diagonally opposite corners of the box.

The child resistant closure may produce an audible response, such as a "click", to indicate to the user that the closure is attached.

So, for example, some capsules may have a compartment containing liquid and another containing powder, or there may be combinations of liquid-gel, gel-powder (each form, eg, liquid, gel, powder in a different compartment).

Suitable compositions that can be divided into different components for use in the present invention include those intended for laundry (cleaning, softening and/or treating the substrate) or machine dishwashing.

Multi-compartment capsules can comprise different parts of a treatment composition which, when combined, constitute the complete treatment composition. This means that the formulation of each part of the treatment composition is different, either in its physical form (for example, viscosity), its composition or, preferably, its colour/opacity.

Preferably, the capsules are made by forming, more preferably by thermoforming, one or more sheets of water-soluble film. During forming or thermoforming, gaps are opened in the sheet. The voids are then filled and a second, often thinner, sheet is superimposed over the filled voids and sealed to the first sheet of film around the edges of the voids to form a flat strip of sealing. Substrate treatment compositions with a viscosity above the range of the invention take longer to settle in the capsule void after filling. If they have not settled at the time of overlapping and sealing the second sheet, the thinner second sheet can be stretched over the stacked formulation which can form the film. This stretching can create leaks by exacerbating pin holes in the thin foil. The viscosity range of the invention is therefore particularly advantageous for such capsules.

Where the chambers of the unit dosage product or capsule are stacked, i.e. not next to each other, but placed on top of another chamber, the product will comprise at least three films in which one chamber is lined by another chamber. chamber that forms above the first.

Furthermore, the relaxation of the first sheet often causes the applied second sheet to bulge when the vacuum is released from the first sheet in the mold.

A multi-compartment capsule is produced using a thermoforming process. Said process can advantageously comprise the following steps to form the capsule:

(a) placing a first sheet of water-soluble polyvinyl alcohol on a mold with sets of cavities, each of which comprises at least two cavities arranged side by side;

(b) heating and applying a vacuum to the film to mold the film into the cavities and hold it in place to form the corresponding voids in the film;

(c) filling the different parts of a substrate treatment composition, each of which may have a different color/opacity (as well as a different treatment function) in the side and center voids, the parts together forming a detergent composition complete;

(d) sealing a second sheet of film to the first sheet of film through the formed voids to produce a multi-compartment capsule having compartments located on opposite sides connected to each other and separated by a continuous internal sealing band;

(e) cutting between the capsules so as to form a series of multi-compartment capsules, each containing a portion of the treatment composition in multiple (one central and two lateral) compartments.

Sealing can be done by any suitable method, for example, heat sealing, solvent sealing, UV sealing or ultrasonic sealing, or any combination thereof. Water sealing is especially preferred. Water sealing can be accomplished by applying moisture to the second sheet of film before it is sealed to the first sheet of film to form the sealing areas.

A preferred thermoforming process uses a rotating drum in which the forming cavities are mounted. A vacuum thermoforming machine using such a drum is available from Cloud LLC. Capsules according to the invention could also be made by thermoforming in a linear array of cavity sections. Hoefliger has suitable machines for this type of process. The following description example is focuses on the rotary process. One skilled in the art will appreciate how it could be adapted without inventive effort to use a linear array process.

bittering agent

The bag of the present invention preferably includes a bittering agent. Bittering agents are generally known. The bittering agents can be any of those described for the packaging.

The bittering agent is usually incorporated into the outer surface of the water-soluble container or covered with a film. Additionally or alternatively, the bittering agent is included in the water-soluble package as a powdered bittering agent in a powder coating applied to the outer surface of the water-soluble package.

In certain embodiments, the bittering agent is incorporated into (included) the water-soluble substrate. For example, the bittering agent can be incorporated into the matrix of a water-soluble polymer included in the water-soluble substrate by dissolving the bittering agent in a water-soluble polymer solution before the water-soluble substrate is formed. . The bittering agent may be present in the water-soluble substrate material in a range of 100 to 5,000 ppm, preferably 200 to 3,000 ppm, more preferably 500 to 2,000 ppm, based on the weights of the bittering agent and the water-soluble substrate. Water. For example, 1 mg of bittering agent can be incorporated into 1 g of water-soluble substrate to provide the bittering agent at 1000 ppm.

The coating of a bittering agent on the surface of the water-soluble substrate can be carried out by known techniques, such as spraying or printing a solution of the bittering agent on the surface of the water-soluble substrate.

The bittering agent may be included on the outer surface of the water soluble substrate in one or more of the printed regions, or may be film coated and/or included in a powder coating. There may be no adverse effect on print quality with UV-cured ink when the bittering agent is included in, film-coated, and/or powder-coated on the outer surface of the water-soluble substrate in the regions printed. In particular, there may be no adverse effect on the quality of material printed with UV-cured ink when the bittering agent is incorporated into the water soluble substrate in the printed regions. In some embodiments, the bittering agent is homogeneously incorporated into the water-soluble substrate. In this way, the inclusion of the bittering agent in the water-soluble substrate and the printing of the water-soluble substrate can be simplified.

Several

The unit dosage products described herein are suitable for use in a substrate treatment process, conveniently a machine laundry or dishwashing process. Therefore, another aspect of the present invention provides for the use of the products or unit dose capsules described herein in a cleaning process, conveniently a machine laundry or dishwashing process. Suitably, the method includes opening the container by unlocking the child-resistant closure, retrieving one or more capsules from the container, placing the capsule(s) in the dosing drum or drawer or any dosing device. of a washing machine before the start of a wash cycle.

The capsules are especially suitable for use in washing machines (substrate) and in dishwashers, among other applications. They can also be used in manual laundry or dishwashing operations. In use, the capsules according to the invention are preferably, and conveniently, placed directly in the liquid that will form the wash liquor or in the area where this liquid will be introduced. The capsule dissolves upon contact with the liquid, thereby releasing the detergent composition from the separate compartments and allowing them to form the desired wash liquor.

Preferably, the capsule is broken within 10 seconds, preferably 30 seconds to 5 minutes, after the unit dose article has been added to 950 mL of 20-21°C deionized water in a 1L beaker, where The water is stirred at 350rpm with a 5 cm magnetic stir bar. By break is meant that the film visibly breaks or splits. Shortly after the film ruptures or splits, the internal liquid composition of the substrate can be seen leaking out of the article into the surrounding water.

A number of proposals and aspects are described in this document, which are intended to be combined in order to achieve enhanced or cumulative benefits. Thus, any aspect can be combined with any other. Similarly, optional features associated with any of the aspects may be applied to any of the other aspects.

With reference to the drawings, the package according to the invention is shown. Twenty (20) multi-compartment water soluble capsules (not shown) produced by a thermoforming process as described above are stacked. 20 of these capsules are packed in a rigid cardboard box 1 having a box construction and providing a receptacle 3 and a hinged closure 5.

The box is made of a rigid, biodegradable, cellulose-based cardboard with a grammage equal to or greater than 225 to achieve a minimum compressive strength of 300 N. This is checked by compressing the box between two plates until the box is flattened. The maximum load (before crushing) is recorded. The container design has 4 pairs of closing elements 7, 9, 11, 13, each of which comprises a tab on the receptacle 3 and a recess in the lid 5. Pair 7 is separated from pairs 11 and 13 by a distance corresponding to the average distance between the thumb and the index finger of an adult hand. Similarly, each pair is separated from 2 of the other pairs by that distance. Only when all the pairs are released simultaneously is it possible to open the lid of the container.

The distance of each pair of closure elements and the arrangement at the corners is such that it is impossible for a child to press all four closure elements simultaneously. The rigidity of the package ensures that the closure elements of each pair are aligned during closure so that children cannot access the package.

Embodiments of the invention will now be described with reference to the following non-limiting drawings in which:

Figure 1 is a perspective view of a lid,

Figure 2 is a perspective view of a base,

Figure 3 is a cross section of a biodegradable container, and

Figure 4 is a schematic side elevation of a biodegradable container.

In detail, figure 1 shows a lid (1) for a biodegradable container. The lid comprises an upper part (2) and depending on each edge of the upper part (2) an upper side wall (3). The side walls shown end in a lower edge (4).

Figure 2 shows a base (8) having a bottom (7) and protruding from the edges of the base (7) are side walls of the base (5) ending in a top edge (6).

Dimensionally, the lid (1) and the base (8) are such that they cooperate by sliding to close the container and maintain the content.

Figure 3 is a cross section along A-A and shows a lid (1) and a base (8) coupled to close the container.

The container also has an absorbent pad (9) to improve protection against leakage from the container. The pad (9) is kept at the bottom of the container, at the base and under any contents of the container. In this way, the absorbent pad (9) minimizes or controls any leakage from the single dose capsules.

The side walls of the lid (3) are shown with an inner surface (3A) and an outer surface (3B). The outer surface (3B) is a bleached surface and has a coated water-based barrier material. The inner surface (3A) is an unbleached surface and has no applied barrier material.

The side walls of the base (5) are shown with an inner surface (5A) and an outer surface (5B). The outer surface (5B) is an unbleached surface and has no coated waterborne barrier material. The inner surface (5A) is a bleached surface and has applied barrier material. The inner surface of the base (5B) also has a barrier material based on thermoplastic elastomers applied.

Figure 4 is a schematic to show the relationship between the dimensions of the lid and the child resistant closure.

In the side view, the width of the lid is 11 cm. This is the width at the point along which the user activates the child resistant closure mechanism. The user uses the fingers and thumb to activate the activation zones of the child resistant mechanism (10) on both sides of the lid. The actual mechanism is not shown, but activating the zone allows the lid to separate from the base when the user presses the zones and pulls the lid away from the base.

EXAMPLE 2

Other examples of unit dose product formulations are given below.

Unit dispensed products comprise a water soluble film printed on the inside.

Figures 5 and 6 show a lid (1) for a biodegradable container. The lid comprises an upper part (2) and depending on each edge of the upper part (2) an upper side wall (3). The side walls shown end in a lower edge (4).

Figure 5 presents a series of four openings (11) in the upper side wall (3) through which air enters and leaves the container by separating the lid (1) and the base (not shown).

Figure 6 has a large opening (11) instead of the four smaller openings of Figure 5.

Figures 7a, 7b and 7c are diagrams that demonstrate how the lid (1) and the base (8) are separated and how the air inside the container momentarily undergoes a rapid change in pressure when the lid and the base are separated and then they come together In both cases, the resulting air pressure changes cause the air inside the container (I), which contains the concentrated fragrance of the unit dose products (14), to agitate so that the air escapes through the openings ( 11) and pass to ambient air (E), where the consumer perceives the improved aromatic effect. The openings are open when the lid and the base are fully separated and are fully closed when the lid and the base are fully attached.

However, the opening and the upper edge of the base (12) are such that the possibility remains that the opening remains closed but the base and lid are partly separated. This can be seen in Figure 7b, where the lid (1) and the base (8) are in the process of separating, but the opening (11) is not yet above the upper edge (12) of the base. This means that the air pressure in the container (I) drops drastically and is only released when the openings are exposed above the top edge of the base (12).
