This disclosure relates generally to compositions which form a dough-like moldable play compound when combined with a solvent, as well as kits, and methods of making and using the same. More particularly, it relates to compositions, kits, and methods of making and using a powder composition which forms a dough-like moldable play compound with a solvent.
The background description provided herein is for the purpose of generally presenting the context of the present disclosure. Work of the presently named inventors, to the extent the work is described in the present disclosure, as well as aspects of the description that may not otherwise qualify as prior art at the time of filing, are neither expressly nor impliedly admitted as prior art.
Toys provide children with the opportunity to learn, engage the senses, spark imagination, and encourage interaction with others. It is often a challenge for toy developers to design a collection which can be used for a purpose other than simply collecting the item itself. Toys can provide additional purposes such as stimulating the child's senses while the child is playing with the toy collection or challenging the child's aptitude for continued learning. For example, water balloons and water bombs are toys which can stimulate a child's senses and engage the child's aptitude for continued learning while the child is playing with the toy, however, the child is left with nothing to collect after a water balloon war but latex rubber that must be discarded in the trash. In another example, trading cards are collectable toys which are limited in their ability to stimulate a child's senses during play. In yet another example, dolls are collectable toys which are limited in their ability to challenge the child's aptitude for continued learning.
However, moldable play compounds provide children with the added benefits of stimulating a child's senses while the child is playing with the toy and challenging the child's aptitude for continued learning. Traditional moldable play compounds include starch and water-based doughs. However, starch and water-based doughs have several disadvantages for use as a modeling compound. Starch and water-based doughs usually exhibit poor plasticity and substantial shrinking upon drying. Among other disadvantages, these doughs also exhibit poor extrudability, which limits the use of extrusion tools for creating shapes as intended by the user. Therefore, developments have been made to provide for modeling compounds that retain their softness and flexibility without drying out too quickly.
Further, many modeling play compounds are pre-packaged prior to handling by the end user. Such pre-packaging requires additional precautions to ensure that the product remains soft and flexible during storage and transportation. Therefore, there remains a need to provide for a dough-like play compound that can be formulated by the end user themselves at a point of use. Further, allowing for the user to make their own moldable play compound provides an opportunity to spark creativity and learning.
Conventional modeling compounds rely on the element of heat to produce soft, flexible textures, which resist retrogradation and hardening over time. For example, high amylose starch can be gelatinized by steam jet cooking at 140° C. The hydration process in presence of heat produces a change in the structure of the starch granule, where the starch-starch molecular interactions are disrupted and replaced by starch-water interactions. When an aqueous starch dispersion is heated, gelatinization occurs, wherein the starch granules absorb water and hydrate, producing a viscous hydrocolloidal solution. The absorption of water, which acts as a plasticizer, and formation of hydrogen bonding with water decreases the number of and size of crystalline regions of starch granules. The gelatinization contributes to the soft, flexible texture, and low viscosity of the modeling compound to resist retrogradation and hardening over time.
However, there remains a need to provide dough-like moldable play compounds which do not require the application of heat to provide soft, flexible, and pliable play compounds. Particularly for the ease and safety of the end user, eliminating or reducing the need for heating of the compounds provides a distinct advantage over current modeling compounds.
Accordingly, it is an objective of the claimed invention to develop a composition which can be formed into a dough-like modeling play compound by a user by adding a solvent to the composition, wherein the user determines the time at which to manufacture the moldable play compound.
A further object of the invention is to provide a dough-like moldable play compound which can be made without the application of heat or need for baking.
A further object of the invention is to provide a kit with at least one powder pre-mix composition and a solvent for forming a moldable play compound.

In some embodiments, a specific mixing container is provided and the container has marked thereon one or more levels which indicate the quantity of solvent and/or powder which should be poured into the container in order to form a suitable moldable play compound with specific characteristics.
In other embodiments, the method includes an apparatus to aid in the formation of the moldable play compound, said apparatus including a base, a cavity and mixing means which, when operated, cause agitation and mixture of a pre-mix powder composition and a solvent located in the cavity, to form the moldable play compound. In an embodiment, the apparatus base includes the cavity or receives an item in which the cavity is formed, and the mixing means includes an arm which is movable with respect to the base. In one embodiment the arm is rotatable.
In a further embodiment, the arm includes at least one, or a number of portions which are located with respect to the cavity so as to cause an agitating, and hence mixing, effect on the solvent and pre-mix powder composition which are located in the cavity at that time. In an embodiment, the arm includes one or more ports through which the powder can be poured to introduce the same for mixing with the solvent in the base. In one embodiment the powder is introduced as the arm is moved. The apparatus may further include one or more capsules into which the formed moldable play compound can be placed and stored prior to subsequent use.
In a further aspect of the invention there is provided apparatus for use in the formation of a moldable play compound by mixing a pre-mix powder and water, said apparatus including a base, a cavity included in, or received by, the base in which the powder and liquid are mixed and wherein a mixing means is provided in a form such that relative rotational movement of the base and at least an arm of the mixing means causes agitation and mixing of the powder and liquid together to form the moldable play compound. In embodiments, the relative rotational movement is caused by the application of a manual movement force on a handle of the mixing means located externally of the cavity. Alternatively, a powered movement means can be provided.
Typically, the handle extends through an aperture in a lid and into the cavity to perform the mixing and the lid prevents spillage of the solvent and/or powder as the same are mixed to form the play compound. In an aspect, the lid is selectively removable from the cavity to allow access to be gained to introduce the solvent and powder and/or remove the formed play compound.
In one embodiment the movement means are provided as an arm which is rotatably movable with respect to the base about a substantially central axis of the cavity. In a further embodiment, the arm includes at least one portion which is located with respect to the base to cause an agitating, and hence mixing, effect on the solvent and ingredients which are located in the base at that time. In one embodiment the said ingredients are provided in a powder form which is premixed.
In an embodiment the arm includes one or more ports through which the powder can be poured to introduce the same for mixing with the solvent in the base. In one embodiment the powder is introduced as the arm is moved and thereby allows the powder to be introduced to the liquid in a manner which reduces the risk of lumping. In an aspect, the apparatus may include one or more capsules into which the formed moldable play compound can be placed and stored prior to subsequent use.
In one embodiment the powder pre-mix composition is provided in a predetermined quantity such that when the user adds the full quantity to a predetermined quantity of solvent, the user can be confident that a moldable play compound with predetermined characteristics will be formed. In an aspect, the powder is provided to a user and the user mixes the powder with the solvent to form a moldable play compound.
In a further embodiment, the methods include a plurality of different powder types which can be selectively used alone or in combination to form a particular moldable play compound. In an aspect, the powders may differ in terms of any combination of colour, consistency, ingredients, and additional components such as glitter, and the like.
In a further aspect of the invention there is provided a play compound said play compound formed by adding a powder with a solvent into a cavity of a container, said powder including a plurality of components required to form the moldable play compound and mixing the powder and solvent for a period of time sufficient to cause the play compound to be formed. In an embodiment, the mixing is performed by a person grasping and moving, typically by shaking, the container. In a further embodiment, the mixing is performed by a person operating a mixing means.
The invention further provides for methods of using a dough-like moldable play compound comprising mixing a quantity of powder pre-mix composition comprising a binding agent, a salt, a humectant, with a quantity of solvent. The powder pre-mix may further comprise a silica and/or silicone, tartaric acid or a salt thereof, or a combination thereof. In embodiments, additional additives may be added to provide a visual and/or tactile effect.
The moldable play compound may be used using an extrusion apparatus to form a variety of shapes or three-dimensional structures on a substrate. In embodiments, the moldable play compounds can be used to form a variety of shapes (such as geometric and non-geometric shapes, linear and non-linear shapes, etc.). The moldable play compounds may be molded with tools, by hand, by molds or using extrusion devices to form a variety of shapes. In addition, the moldable play compound can be used in a pen-like device or any device capable of applying the moldable play compound onto a surface, such as paper or a hard surface, to produce art like effects.
In some embodiments, the moldable play compound can be adhered onto a substrate and allowed to remain undisturbed for a suitable period of time to allow the moldable play compound to dry and adhere onto the substrate. In some embodiments, the moldable play compound can function as an adhesive. In some aspect, the moldable play compound has an adhesion property permitting the moldable play compound to adhere onto a variety of substrates or to be glued together to form a three-dimensional structure.
