These unit dose products are desired by consumers because they provide a convenient, efficient, and clean method of administering the desired product. However, one challenge for manufacturers is how to package such products in an aesthetically pleasing manner while maintaining ease of use. This is especially true when attempting to bundle large numbers of such products. Summary of the Invention [Problem to be solved by the invention]

[0008] Unit dose articles, such as those used for dish care and laundry, are highly desired by consumers for their convenience of use. When these types of articles are sold in bulk, they tend to be packaged in a bucket-style fashion, where the unit doses are not arranged in a specific pattern but are removed from a haphazard stack or pile when used. Some of this is due to the design of the unit dose product itself, but it can lack aesthetic appeal and may not be the best option for all unit dose article types.

[0009] Some unit dose types are more suitable for ordered packaging. These can include flat or substantially flat. A substantially flat unit dose type is one whose major surfaces are essentially parallel. A substantially flat unit dose type can be stacked on top of one another in at least three layers without tipping over. Depending on the unit dose, ordered packaging can allow more unit doses to be placed in a package than bucketing. It can also allow for more efficient use of space. Ordered packaging can also protect the unit doses from breakage or damage to the seal from shearing that occurs when the unit doses rub against one another.

[0010] The first part of a package is the outer packaging. This is the packaging that encloses the product and is visible to the consumer. One common external product packaging is the carton. Cartons are often square or rectangular in shape and often have a consistent shape. Here, the inventors wanted to design a carton with a unique shape. As seen in Figures 1-8, the inventors designed a carton with both non-right-angle corners and right-angle corners. Right-angle corners are corners where the walls meet to form approximately a 90° angle. Non-right-angle corners can include, for example, rounded corners, chamfered corners, concave corners, star-shaped corners, beveled corners, or combinations thereof. Non-right-angle corners can include any shape that gives the overall impression of a corner that is not a right angle. Using a non-right-angle corner on a portion of a carton can present several challenges. For example, if the carton has a lid, the lid needs to have a non-right-angle corner of a complementary shape. Additionally, the lid requires adequate clearance from the rest of the carton in order to open and close properly.

[0011] Most cartons with a mix of corner shapes, such as both non-square and square corners, have two separate pieces that are formed separately to simplify the fit of the lid and base and allow for easy opening. However, the design of the present invention can be made from a single piece of carton board. This means that the lid is integral with at least a portion of the carton. This attachment of the lid to a portion of the carton leaves a smaller gap for the lid, a challenge that must be overcome. The inventors have overcome this challenge.

[0012] In these embodiments with rounded corners, the different curvatures of the rounded corners on the bottom of the carton and the corresponding rounded corners on the lid can be used to allow sufficient clearance of the lid from the base portion. For example, when the lid overlaps the outside of the base portion, the curvature of any rounded corner on the lid will be greater than the curvature of the corresponding rounded corner on the base portion. The opposite is true when the lid is placed inside the base portion in a closed configuration. Curvature can be measured by its radius of curvature. For curves, the radius of curvature is the radius of a circle that best fits the normal portion of the curve. Thus, for rounded corners, one would find the circle that best fits the normal cross-section of the rounded corner and look at the radius. Measuring the radius of a circle can be done according to any known standard. For sufficient clearance between the lid and base portions, a curvature difference between the lid and base portions of at least 2%, 3%, 4%, 5%, 7%, 10%, 12%, 15% to about 50%, 70%, 80%, 90%, or 100% or more can be utilized.

[0013] In embodiments with non-square corners where the lid overlaps the exterior of the base and where the lid is integral with at least a portion of the carton, some additional ways to help ensure lid clearance from the base include having the lid protrude beyond the base and having the lid have a larger area than the base (excluding the lid and any panel portions on the base).In embodiments with non-square corners where the lid is disposed inside the base and where the lid is integral with at least a portion of the carton, some additional ways to help ensure lid clearance from the base include having the base protrude beyond the lid and having the base have a larger area than the lid (excluding the lid and any panel portions on the base).

[0014] Another challenge encountered with this design is the consistency of the shape of the non-square corners in the finished carton. Maintaining the shape of non-square corners, such as rounded corners, helps provide proper clearance for the lid, and therefore consistency of their shape is required during the manufacturing process to allow for a uniform, workable finished carton. To maintain a consistent non-square corner shape during manufacturing, score marks can be added to the portions of the panels and / or tabs utilized to create the non-square corners to indicate where the non-square shape begins and / or ends. These marks can be visible to the human eye for manual construction of the carton and / or have sufficient contrast to guide automation on the manufacturing line. Preferably, these marks are invisible to the consumer in the finished carton.

[0015] When cartons are made from a single piece of paperboard, several modifications to the manufacturing process also contribute to a more uniform finished carton shape. Using knockdown flats and forming the carton in an ordered manner allows for non-right-angle corners, such as rounded carton corners, without requiring hard folds or multi-piece assembly. Knockdown flats are folded parallelograms in which the carton is partially assembled at a separate station and / or location from the final assembly. Ordered assembly can include forming and adhering the bottom of the carton first, then forming and adhering the lid. If the lid overlaps the outside of the bottom, the lid can be formed around the bottom to ensure the proper shape (e.g., curvature) of the non-right-angle corner is maintained. If the lid is placed inside the bottom, ordered assembly can include forming and adhering the lid first, then forming the base around the lid to help maintain the proper shape of the non-right-angle corner.

[0016] Once a lid gap with a consistent angular shape is established, e.g., to have a consistent curvature between the base and lid throughout manufacturing, that gap must be maintained for filling and / or use. To maintain that gap, the carton must be sufficiently rigid so that it does not distort excessively during product filling, shipping, or handling by the consumer. Rigidity can be added to the carton through the materials used to make it and / or by building structures into the carton. Here, when the carton material is bent to form the carton, the amount of rigidity that can be developed in the material itself is limited.

[0017] For paperboard, a minimum caliper is required to allow sufficient rigidity, and a maximum caliper is required to allow bending to form the carton. The exact caliper required may depend on whether the carton utilizes support structures that contribute to the carton's rigidity. In that case, a lower caliper material may be used. Additionally, a smaller overall package size may allow for a lower caliper material. Cartons may be made from paperboard having a caliper of about 0.008 inches to about 0.028 inches, 0.012 inches to about 0.028 inches, 0.016 inches to about 0.028 inches, and most preferably about 0.016 inches to about 0.024 inches. Paperboard may include, for example, clay-coated newspaper backboard, folding boxboard, solid bleached sulfate, natural kraft, coated unbleached kraft, and coated recycled paperboard.

[0018] As noted above, if the carton material alone does not provide sufficient rigidity, the carton's rigidity can be supplemented by structure. Insufficient structure within the carton can distort the carton's shape and eliminate the lid clearance that was carefully designed into the carton's formation. Providing structure to the carton can be accomplished in several ways. For example, the carton can have one or more interior walls that extend from non-right-angled, e.g., rounded, corners and are glued in place, or the carton can include structural support. Such structural support can provide horizontal support, vertical support, or a combination thereof. Structural support can also be provided in the form of an internal wrap and / or internal structure, which are described in more detail below.

[0019] Another portion of the organized packaging can include internal structures and / or internal packaging. Internal structures can include, for example, product guides and / or dividers that can help position products during product filling and / or help maintain a desired order of products within the packaging. The product guides and / or dividers can be an integral part of the carton or added separately. Furthermore, these structures can be designed to provide additional structure to the carton itself. For example, these structures can be adjacent to (or even touching) the upper side of the base and / or the underside of the lid to help minimize the amount of deformation of these two structures when pressure is applied to one or both. The same is true if these structures are positioned in a horizontal fashion extending from the front to the back, which helps minimize deformation of those portions of the carton when pressure is applied. In either configuration, these structures can also help provide structure to the carton, for example, to minimize twisting of the carton while it is being handled by the consumer.

[0020] However, one potential problem with packaging a product directly into an outer package is that if there is a problem with the packaging manufacturing process, the finished product has nowhere to go and can become stuck on the production line, potentially creating a cascade of problems. One solution to this problem is to utilize inner packaging. The use of inner packaging allows the finished product to be packaged within the inner packaging without interruption if there is a problem with the manufacturing of the outer packaging. The use of inner packaging also allows the product to be stored and / or used in a modular configuration. This allows flexibility in the size of the outer package, the number of units included in the package, and how the inner packaging can be arranged within the outer package. For example, a product may be shipped in one configuration within the outer package and then rearranged into different configurations for use by the consumer.

[0021] Inner packaging has other potential uses. It can capture product leakage so that the product in the remaining portion of the outer packaging is not affected. Inner packaging can also help maintain the product in a desired configuration, minimizing the risk of product shifting during shipping or shelf storage. Inner packaging can also help prevent product compression during packaging, shipping, and / or storage.

[0022] The inner packaging can include, for example, a sleeve, a carton, a tray, a bag, or a combination thereof. The sleeve and bag can be made of different materials, such as film, paperboard, paper, wax paper, foil, cellophane, plastic, or any combination thereof. The sleeve and bag can help maintain the life of the fragrance in the unit-dose product by protecting it from exposure to air. The sleeve and bag can also include an opening, if desired, to allow controlled release of the fragrance contained within the unit-dose product. The sleeve and bag can also include a closure, such as, for example, a seal, a snap, a hook and loop fastener, a connecting flange, or any combination thereof.

[0023] An example of an internal packaging is a tray. As generally discussed above, loading product into a tray can divert finished product from problem areas in the manufacturing process without the need to accumulate and discard it. Another advantage of trays or similar structures is that they can be made to fit different numbers, allowing flexibility in sizing the external packaging to best meet consumer needs. Loading product into trays also helps minimize the amount of contact between individual unit doses and prevent damage from such interactions. Trays can be oriented vertically, horizontally, or a combination thereof to help control how the sizes appear relative to each other on the shelf. This also gives the product a neater appearance and a better consumer experience when opening the outer packaging. Trays can be the same size and shape within a carton, or a combination of sizes and shapes can be used within a carton.

[0024] An additional advantage of using an inner packaging such as a tray is that the tray's structure can be utilized to help provide additional support to the outer packaging. For example, portions of the tray walls, such as side walls, can be extended to provide internal vertical support from the base to the lid, strengthening the overall package. Packaging the inner structures so that they essentially occupy a majority of the space within the outer packaging can also provide horizontal support for the carton. These can help provide support to prevent unintentional twisting and / or bending of the carton. The inner packaging can also help prevent and / or minimize deformation of the lid or base portions when they are under pressure, for example, from being transported or opened. The inner packaging also helps to maintain an even distribution of product weight within the carton, such as unit doses, and helps prevent product shifting during shipping, shelf stacking, and use. The inner packaging also allows for modular use of the product. For example, a consumer can pull a tray of product from a larger package such as a carton and store the tray near a location or point of use while placing the remainder of the product in the outer packaging in a different storage location.

[0025] When utilizing cartons with non-uniform shapes or shapes that do not match the shape of the products being loaded into the carton, additional structure can be added to the carton to allow for more uniform loading of the products. For example, in a carton with two non-right-angle corners, structure can be added to make the interior of the carton square or rectangular, allowing for better packaging of primarily square and / or rectangular products. This structure can be, for example, an interior wall or compartment.

[0026] carton The carton is described herein with reference to the drawings shown. The carton 10 shown in FIGS. 1 and 7-8 can have one or more non-right-angle corners, such as rounded corners 20 and chamfered corners 180. The carton can have one to four non-right-angle corners, preferably one to three non-right-angle corners, more preferably two to three non-right-angle corners, and most preferably two non-right-angle corners. The carton can have one to four rounded corners, preferably one to three rounded corners, more preferably two to three rounded corners, and most preferably two rounded corners. The carton can have one to four chamfered corners, preferably one to three chamfered corners, more preferably two to three chamfered corners, and most preferably two chamfered corners. The carton 10 can have one or more right-angle corners 30. The carton may have one to three right-angled corners, preferably two to three right-angled corners, and most preferably two right-angled corners. The carton may have two rounded corners and two right-angled corners. The carton may have two chamfered corners and two right-angled corners. The carton may have any desired shape. Preferably, the carton has a generally rectangular shape.

[0027] The carton may have a bottom 40 and a lid 50, as seen in Figures 2-5. The bottom 40 may include a base 60, a front side 70, a back side 80, a first side 90, and a second side 100. The base 60 may help define the shape of the bottom of the carton 10. Thus, the base 60 may have one to four non-right-angle corners, preferably one to three non-right-angle corners, more preferably two to three non-right-angle corners, and most preferably two non-right-angle corners. The base 60 may have one to four rounded corners 20, preferably one to three rounded corners, more preferably two to three rounded corners, and most preferably two rounded corners. The base 60 may have one or more right-angle corners 30. The base 60 may have one to three right-angled corners, preferably two to three right-angled corners, and most preferably two right-angled corners. The base 60 may have one to four chamfered corners 180, preferably one to three chamfered corners, more preferably two to three chamfered corners, and most preferably two chamfered corners. The base 60 may have two rounded corners and two squared corners. The base 60 may have two chamfered corners and two right-angled corners.

[0028] The base 60 may include one or more panels 110. The one or more panels may include walls. The one or more panels may be a first side 90, a back side 80, a front side 70, and / or a second side 100. When in a folded configuration, the first side 90, the back side 80, the front side 70, and / or the second side 100 may extend upward from the base 60. The base 60 may include one or more guides. Guides may be used to aid in loading products into the carton. For example, guides may aid in proper placement of inner packaging, such as a removable tray. The guides may be panels extending upward from the base 60. There may also be a score line 120 disposed between the base 60, the first side 90, the back side 80, the front side 70, and / or the second side 100. The score line 120 may be continuous or discontinuous. It may or may not penetrate the material. The score lines 120 may be used as fold lines to delineate where the material should be folded and / or to help provide a more uniform fold at certain points.

[0029] The base 60 may include one or more structural shelves. The structural shelves may extend upward from the base 60 toward the underside of the lid 50. The structural shelves may extend to a height that is at least 80% of the height between the base 60 and the underside of the lid 50. The structural shelves may extend to a height that is approximately 80% to 100% of the height between the base 60 and the underside of the lid 50. The structural shelves may contact both the base 60 and the underside of the lid 50.

[0030] Each of the panels 110 may further comprise an additional panel. For example, the front side 70 may comprise a panel 110. This panel may, for example, form the top 140A of an interior compartment 140 of the carton 10 (see FIGS. 3 and 4). The panel forming the top of the compartment 140 may further comprise one or more panels. This additional panel may, for example, form a wall 140B (FIG. 5) of the compartment 140. This wall 140B may act as a guide for placement of a removable tray or other internal packaging. The compartment 140 may form a void within the carton 10. This void may be used, for example, to contain desiccants to help control moisture inside the carton 10, product samples, free products, etc. Flat surfaces of the compartment 140 may be used to provide consumers with information, such as interesting facts, coupons, instructions, etc.

[0031] Compartment 140 can also aid in the structural integrity of the carton by helping to keep the inner packaging aligned. If the packaging includes non-right-angle corners, this can create an asymmetrical shape on the interior of the package. This asymmetry can cause difficulties in packaging the product. By including compartment 140, the shape of the interior of the package can be symmetrical, which may be easier to fill.

[0032] Each panel 110 may further include one or more tabs 130 extending therefrom for joining the panel to another portion of the carton. The tabs may join portions of the carton, for example, with an adhesive. The panels may also interlock with another portion of the carton to join the components together. Each panel may include about 1 to about 10 tabs, about 1 to about 8 tabs, about 1 to about 6 tabs, about 1 to about 4 tabs, about 1 to about 3 tabs, about 1 to about 2 tabs, or any combination thereof. For example, the rear side 80 may include one or more tabs 130, preferably two tabs 130. The front side 70 may include one or more tabs 130, preferably two tabs 130. The panel forming the wall 140B of the compartment 140 may include one or more tabs 130, preferably one tab 130.

[0033] Tab 130 extending from wall 140B may be attached to base 60 of carton 10. Tab 130 extending from wall 140B may be attached to base 60 so that it resides inside compartment 140 (FIG. 3). However, benefits have been observed from attaching tab 130 extending from wall 140B to base 60 and located outside compartment 140. During manufacturing, the carton is folded upon itself when the base portion is formed. Gluing the tab to the base inside the compartment would result in an uneven number of paperboard layers in this partially folded configuration, making it more difficult to complete assembly and more inefficient to ship partially constructed cartons to another location for completion.

[0034] The lid 50 may have an upper side and a lower side. In a closed configuration, the upper side is visible, while the lower side is inside the closed carton. The lid 50 may be integral with the bottom 40 of the carton 10 or may be separate from the bottom 40. If the lid 50 is integral with the bottom 40, the lid 50 may be attached to the first side 90, rear side 80, front side 70, and / or second side 100 in any configuration that opens to allow access to the contents of the carton 10. The lid 50 is preferably attached to one of the first side 90, rear side 80, front side 70, or second side 100, with a score line 120 disposed between the lid 50 and the side to which the lid 50 is attached. Preferably, the lid 50 is attached to the rear side 80 with the score line 120 disposed therebetween.

[0035] The lid 50 can help define the shape of the top of the carton 10. Accordingly, the lid 50 can have one to four non-right-angle corners, preferably one to three non-right-angle corners, more preferably two to three non-right-angle corners, and most preferably two non-right-angle corners. The lid 50 can have one to four rounded corners 20, preferably one to three rounded corners, more preferably two to three rounded corners, and most preferably two rounded corners. The lid 50 can have one or more right-angle corners 30. The lid 50 can have one to three right-angle corners, preferably two to three right-angle corners, and most preferably two right-angle corners. The lid 50 can have one to four chamfered corners 180, preferably one to three chamfered corners, more preferably two to three chamfered corners, and most preferably two chamfered corners. The lid 50 may have two rounded corners and two square corners. The lid 50 may have two chamfered corners and two square corners. If the base has a particular shape, the lid can mirror that shape. For example, the base 60 may have two rounded corners 20, and the corresponding lid 50 may have complementary rounded corners 20 (e.g., FIG. 4).

[0036] The lid 50 may include one or more panels 110. The one or more panels 110 may include walls. The one or more panels 110 attached to the lid may have a score line 120 disposed between them and the lid 50. The one or more panels attached to the lid may be folded such that the panels at least partially overlap one or more of the first side 90, the back side 80, the front side 70, or the second side 100 when the carton 10 is in the closed configuration (see, for example, FIG. 2). Preferably, the panels overlap at least a portion of the first side 90, the front side 70, and the second side 100. The overlap may occur on either the outside or the inside of the carton 10, preferably on the outside of the carton 10.

[0037] The lid 50 may include one or more guides. Guides may be used to aid in loading product into the carton 10. For example, a guide may aid in proper placement of an inner package, such as a removable tray. A guide may be a panel extending downward from the lid 50.

[0038] The lid 50 may include one or more structural ledges. The structural ledges may extend downward from the lid 50 toward the base 60. The structural ledges may extend to a height that is at least 80% of the height between the base 60 and the underside of the lid 50. The structural ledges may extend to a height that is approximately 80% to 100% of the height between the base 60 and the underside of the lid 50. The structural ledges may contact both the base 60 and the underside of the lid 50.

[0039] The lid 50 may include a notch 150 (see FIG. 2 ) or a closure tab 160. The notch 150 or closure tab 160 may be located on the lid and / or one of the lid panels 110. For example, the notch 150 or closure tab 160 may be located at least partially along the score line 120 between the lid 50 and the lid panel 110. The notch 150 may be any shape. If the lid 50 includes a notch 150, a corresponding component on the base 40 includes a closure tab 160. For example, if the lid 50 includes a notch 150 located at least partially along the score line 120 between the lid 150 and the panel 110, and the panel 110 overlaps at least a portion of the front side 70 when folded downward in the closed configuration, the closure tab 160 may be located on the panel 110 attached to the front side 70 along the score line 120 between the front side 70 and the panel 110. When the carton 10 is in the closed configuration, the closure tab 160 engages the notch 150 to help maintain the lid 50 in the closed position. The lid may also include multiple notches and / or multiple closure tabs.

[0040] An audible sound may be heard when the closure tab 160 engages the notch 150. Such a sound, if present, may alert a user of the carton 10 that the carton is indeed closed. The length of the closure tab may affect the loudness of the audible sound.

[0041] The interlocking of the closure tab 160 and the notch 150 also provides additional structure for the carton 10 .

[0042] The lid may also include a closure other than or in addition to a notch. The closure may be reusable. Closures for lids may include, for example, snaps, hook and loop fasteners, interlocking flanges, tabs and ties, press and seals, or any combination thereof.

[0043] The carton 10 can include a front side 70. The front side can be attached to the base 60 with a score line 120 therebetween. The front side 70 can be longer than the lid 50. At least a portion of the front side 70 can be adjacent to the first side 90. There can be an arcuate transition 170 between the first side 90 and the front side 70. This arcuate transition can be formed when a portion of the front side 70 curves toward the first side 90 and is attached to the first side 90. It can also be formed when a portion of the first side 90 curves toward the front side 70 and is attached to the front side 70. The first side 90 and the front side 70 can be attached via adhesive placed on a tab on the front side 70 and adhered to the first side 90, or by adhesive placed on a tab on the first side 90 and adhered to the front side 70. This arcuate transition 170 may form a rounded corner 20 at the bottom 40 of the carton 10 .

[0044] At least a portion of the front side 70 may be adjacent to the second side 100. There may be an arcuate transition 170 between the front side 70 and the second side 100. This arcuate transition may be formed when a portion of the front side 70 curves toward and is attached to the second side 100. It may also be formed when a portion of the second side 100 curves toward and is attached to the front side 70. The second side 100 and the front side 70 may be attached via adhesive placed on a tab on the front side 70 and adhered to the second side 100, or by adhesive placed on a tab on the second side 100 and adhered to the front side 70. This arcuate transition 170 may form a rounded corner 20 at the bottom 40 of the carton 10.

[0045] The carton 10 can include a rear side 80. When in the closed configuration, the rear side 80 can be generally parallel to the front side 70. The rear side 80 can be attached to the base 60. The rear side can be attached to the lid 50. It can be attached to the base 60 and / or the lid 50 with a score line 120 therebetween. The rear side 80 can include one or more panels 110. Additionally, the rear side 80 can include one or more tabs 130. For example, the rear side 80 can include two tabs 130.

[0074] A fiber element may include two or more different active agents that are compatible or incompatible with each other. A fiber element may include an active agent within the fiber element and an active agent on the exterior surface of the fiber element, such as an active agent coating on the fiber element. The active agent on the exterior surface of the fiber element may be the same as or different from the active agent present within the fiber element. If different, the active agents may be compatible or incompatible with each other. One or more active agents may be uniformly or substantially uniformly distributed throughout the fiber element. One or more active agents may be distributed as discrete regions within the fiber element. Active agents are discussed in more detail below.

[0075] particle The fiber water soluble unit dose can also include one or more particles, which can be, for example, intertwined with the fiber elements, added after the fiber elements are formed into plies, added between plies, added to the outer surface of the fiber water soluble unit dose, etc.

[0076] The particles may have a particle size distribution such that D50 is greater than about 150 micrometers and less than about 1700 micrometers. The particles may have a particle size distribution such that D50 is greater than about 212 micrometers and less than about 1180 micrometers.

The particles may have a particle size distribution such that D10 is greater than about 250 micrometers and D90 is less than about 1000 micrometers.

[0077] The particles may contain a rheology modifier. For example, the particles may comprise an alkoxylated amine, preferably an alkoxylated polyamine, more preferably a quaternized or non-quaternized alkoxylated polyethyleneimine, where the alkoxylated polyalkyleneimine is a polyalkyleneimine core having one or more alkoxy side chains attached to at least one nitrogen atom of the polyalkyleneimine core, an ethylene oxide-propylene oxide-ethylene oxide (EOx1POyEOx2) triblock copolymer (where x1 and x2 are each in the range of about 2 to about 140, and y is in the range of about 15 to about 70), or a combination thereof.

[0078] The particles may contain fillers. Exemplary fillers include sodium carbonate, silica, zeolite-A, or combinations thereof.

[0079] The particles may contain an active agent, as described more fully below.

[0080] activator The fiber water-soluble unit doses described herein can contain one or more active agents. The active agent may be contained in the fiber structure, within fiber elements, within particles, or any combination thereof. The active agent may be present in the water-soluble unit dose at a level of about 1% to about 80%, about 2% to about 75%, about 5% to about 70%, about 5% to about 65%, about 5% to about 60%, about 5% to about 55%, or about 5% to about 50%.

[0081] One active agent useful herein is a surfactant. One suitable surfactant is alkyl alkoxylated sulfate. However, these types of surfactants tend to undergo a very viscous hexagonal phase at higher concentration levels (e.g., about 15%). This hexagonal phase transition can cause problems when higher levels of alkyl alkoxylated surfactant are included in the fiber components. For example, if too much alkyl alkoxylated sulfate is incorporated into the fiber components, the dissolution of the water-soluble fiber unit dose in water may be significantly slowed, or even worse, undissolved solids may remain. Therefore, it is preferred that this particular surfactant be included in the water-soluble fiber unit dose in particulate form, or its amount be limited to less than 15% within the fiber components. In one embodiment, the fiber components may be substantially free of or may contain alkyl alkoxylated sulfate.

[0082] Additional suitable surfactants may include those with relatively low hydrophilicity that are unlikely to form a viscous hexagonal phase upon dilution. These surfactants may include, for example, non-alkoxylated C6-C20 linear or branched alkyl sulfates (AS), C6-C20 linear alkyl benzene sulfonates (LAS), and combinations thereof. The surfactant may be a C6-C20 linear alkyl benzene sulfonate (LAS), or a C6-C20 linear alkyl benzene sulfonate (LAS). 20The surfactant may be a linear alkylbenzene sulfonate (LAS). LAS surfactants are well known in the art and can be readily obtained by sulfonating commercially available linear alkylbenzenes. Exemplary C6-C8 surfactants that can be used include: 20 Linear alkylbenzene sulfonates include C6 to C 20 Alkali metal, alkaline earth metal, or ammonium salts of linear alkylbenzenesulfonic acid, such as C 11 ~C 18 or C 11 ~C 14 Examples include sodium, potassium, magnesium, and / or ammonium salts of linear alkylbenzene sulfonic acid. 12 Sodium or potassium salts of linear alkylbenzene sulfonic acid, e.g., C 12 The sodium salt of linear alkylbenzene sulfonic acid, i.e., sodium dodecylbenzene sulfonate, can be used as the first surfactant.

[0104] Production method A solution of a filament-forming composition is provided. The filament-forming composition may include one or more filament-forming materials and, optionally, one or more active agents. The filament-forming composition passes through one or more die block assemblies including multiple spinnerets to form multiple fiber elements including one or more filament-forming materials and, optionally, one or more active agents. Multiple die block assemblies can be used to spin fiber elements in different layers, where the fiber elements in the different layers have different compositions from each other or the same composition as each other. Two or more die block assemblies arranged in series can be provided to form three, four, or any other integer number of layers in a given ply. The fiber elements are deposited on a belt moving in the machine direction (MD) to form a first ply.

[0105] Particles can be introduced into the flow of fibrous elements between the die block assembly and the belt. The particles can be fed from a particle receiver to a belt feeder, or optionally a screw feeder. The belt feeder can be configured and controlled to deliver a desired particle mass to the process. The belt feeder can provide an air knife that suspends the particles in an air stream and directs them toward the fibrous elements, forming a particle-fiber layer of mixed fibrous elements and particles, which can then be deposited onto the belt.

[0106] A first ply can be provided to form the water-soluble product. A second ply can be provided separately from the first ply. The first and second plies are superimposed on one another. Superimposed means one is disposed above or below the other, although additional plies or other materials (e.g., active agents and / or particles) may be disposed between the superimposed plies. A portion of the first ply can be joined with a portion of the second ply to form the water-soluble product. Each ply can include one or more layers.

[0107] The layers may be sealed at the edges using any type of seal, including but not limited to, ultrasonic, pressure, heat, the use of water-soluble adhesives, and combinations thereof. The seal is preferably made using a pressure seal, for example.
