Abstract
The process immerses a plurality of smaller solids in a liquid softening/solvent/bonding agent (i.e. water, oils, solvent or some other combination). This reagent reacts with the solids over a period of time so that when the cavity containing the solid/liquid mixture is compressed, the solids and any other additives (i.e. oatmeal, spices, other foreign objects, etc . . . ) are forced together and force the liquid softening/solvent/bonding agent out. The expelled liquids are removed from the solids and additives which are then allowed to dry/bond/fuse thereby forming a solid bond. Whereas there is prior art utilizing aspects of this process specifically in soap scrap bonding, this method is the only method of compressing solids that does not require electricity and where the disparate solid pieces and the bonding agent/liquid are all contained in one vessel that enable the solids to react with the liquids and then be compressed removing the bonding agent/liquid and leaving only the solids which can then form a permanent bond, all in one device (see FIG. 8: Novel Mould Assembly , FIG. 10—Mould Assembly Option, FIG. 12—Novel Mould Assembly with Option Plunger Design). Furthermore, this design can incorporate the collection and if desired recycling of the reagent within the mould itself (i.e. a hollow cavity in the plunger and if necessary a collection vessel attached to the cap and/or stabilizing base). Finally, the plunger design allows the device to be used with or without any mechanical aids to prevent it from binding during longitudinal movement during compression of the mould/plunger. This, first of all, simplifies the mechanics of the device and allows the mould to be used by young and old alike regardless of ability.
This device will have applications in many industries but especially the craft industry (i.e. cheese making and soap making).

Description
[0009] The plunger is the most unique and innovative aspect of this design. It can be any cross section except the outside cross section must match the inside cross-section of the enclosure closely while allowing longitudinal movement within the enclosure and fluid movement between the outside surface of the plunger and the inside surface of the enclosure. The plunger may also have holes or channels in the sides to allow the softening/bonding/solvent fluid to escape the cavity formed by the cap, enclosure and plunger when under pressure yet not allow the solids to escape. The plunger must be able to move freely longitudinally within the enclosure. Furthermore, the plunger can be hollow with holes leading from the outside longitudinal surface of the plunger to the inner cavity (see FIG. 1—Plunger Design Option). When the liquid softening/bonding agent is exuded from the solid/liquid mixture in the mould, it is forced up the sides between the solid sides of the plunger and the solid enclosure. This will occur until it reaches the level of the holes or inlet where the liquid is able to enter the cavity in the middle of the plunger and be collected inside the plunger cavity. This prevents the liquid agent from overflowing the mould creating a mess and making it difficult to recycle the liquid softening/bonding agent. Furthermore, a circumferential channel or groove may be inscribed at the level of the inlet holes to enable/encourage the liquid to travel circumferentially until it reaches the inlet holes to the cavity in the middle of the plunger. Further a sealing gasket between the plunger and enclosure between the level of the inlet to the centre of the plunger and the end of the plunger where the axial force is being applied. This may be used to encourage the fluid to collect in the cavity in the middle of the plunger. The enclosure should have level indicators guiding the user the recommended level above which there should be no liquid which will prevent the softening/bonding agent from reaching the top of the enclosure prior to reaching the level of the intake that allows the liquid/bonding agent to flow into the cavity in the middle of the plunger. Other shapes of the plunger can be used to create a collection cavity in the plunger to collect the exudates (i.e. a cup shaped plunger base with central post leading up to a cap for applying axial force to the plunger) (see FIG. 2—Plunger Design Option). The salient feature is that the exudates are able to travel to and be collected in a cavity inside the plunger. As a precaution against misuse of the device, any exudates that escapes the mould could he collected in a vessel formed in the cap or the stabilizing platform. Another unique feature of the plunger is that the length of the plunger cross-section that closely matches the interior cross-section of the enclosure is long enough that by virtue of the extended length of the plunger, this maintains the alignment of the plunger body within the enclosure when an axial force is applied preventing the plunger from binding within the enclosure “shaft”. This length of this section of the plunger would be such that the height of the alignment section be at least as great as the longest distance diagonally from the inside of one edge of the enclosure to the opposite edge. In this way, there is no need for mechanical devices to ensure alignment of the plunger in the enclosure to prevent binding while an axial force is applied to the top of the plunger. Finally, although not crucial to operation of the cold compression mould, the overall length of the plunger shall be at least as long as the outside longitudinal length of the enclosure so that when the cap is removed by the user, the newly formed solid can be expelled from the enclosure axial force applied to the plunger.
[0010] Enclosure
[0011] Inside and outside of the enclosure may be any shape/cross-section but the inside cross-section must allow the plunger to move freely longitudinally inside and be of similar shape to the exterior cross section of the plunger while allowing the softening /bonding agent a route to escape between the walls of the plunger and the enclosure when an axial force is applied to the plunger but not allowing the solids to escape the cavity formed by the cap (see FIG. 5: Cap Option or FIG. 6—Cap Option), the inside of the enclosure and the bottom of the plunger (see FIG. 3: Fnclosure or FIG. 4—Enclosure Option). The enclosure may have mechanical or pressure means of securing the cap in place either at one or both ends. The cross-section of the outside of the enclosure can be different from the cross section of the inside of the enclosure. However, the cross-section of the outside of the enclosure must allow the cap to form a liquid tight seal on the bottom and/or top. Further, the cross-section of the inside of the enclosure must allow the plunger to move longitudinally within the enclosure (i.e. typical cross-sections would be but are not limited to round or a polygon. Other shapes are possible but are not limited to dogs, flowers, etc . . . ).
[0012] Cap
[0013] The cap is designed to create a fluid tight seal on one end or both ends of the enclosure (see FIG. 5: Cap Option or FIG. 6—Cap Option). It may be constructed as one piece or as multiple pieces. May also include a gasket to seal the end. In any case, it will provide a fluid tight seal through either a pressure fit or other mechanical means. Exterior of the cap may be any shape and may incorporate a method of collecting the exuded fluid which could be a permanent part of the cap or an attachment. As a typical example, the cap may be a single moulded piece that secures to one or either end of the enclosure or two pieces with the edges of the cap providing the securement of the cap to the enclosure through pressure/friction or other mechanical means and the end allowing interchangeable end pieces which may or may not be imprinted or embossed with art or other shapes to be imprinted or embossed on the softened soap or other solids (see FIG. 5: Cap Option) A second example of Cap design could be a flat surface with mechanical attachment to the enclosure forming a fluid tight seal with the enclosure which may or may not ruse a gasket (see FIG. 6—Cap Option). Finally, the outside cross-section and shape of the cap may be such that it can be secured to and not preclude the use of an optional stabilizing base. Alternatively it may incorporate a larger stabilizing base.
[0014] Stabilizing Base
[0015] A base may be permanently or temporarily attached to the cap using either pressure or other mechanical means (see FIG. 7: Stabilizing Base). This base may provide extra stability to the mould during compression of the solids and softening agent meant to exude the softening/bonding agent from the solids. It may also include a method of collecting the exuded softening fluid. Furthermore, the stabilizing base can secure the mould while being rigid enough and of such a size so the stabilizing base itself may be secured from moving with the use of the user's or other persons weight or some other mechanical means. Typical materials would be metals or rigid plastics. The ability to use your own body weight to stabilize the mould and use your own body weight to apply an axial force to the plunger (i.e. hands or feet) increases the usability of the device and opens the process up to a wider audience making it usable regardless of age or ability increasing the likelihood of mass adoption of the process and device.
