Definitions
- the present invention relates to a figure, and in particular, to a material or composition that can be used to form the figure.
- the present invention also relates to method of making the figure.
- thermoplastic material such as resin
- these figures usually have multiple components or body parts that are molded using the thermoplastic material.
- the body parts are hollow and not solid. The molding of such parts results in the walls of a body part having a uniform thickness.
- the parts are generally lightweight.
- such conventional figures and body parts typically lack any pleasing aesthetic features.
- a toy figure has at least one solid, molded part with a varying thickness.
- the toy figure is a collector or fashion doll that has particular characteristics or properties.
- One characteristic is the feel or touch of the material of the toy figure.
- the material has a cool feel or touch, resembling that of a porcelain material.
- Another characteristic is that the toy figure material aesthetically resembles or appears to look like porcelain.
- Another characteristic is that the toy figure material has a specific gravity in a particular range which gives the toy figure a heavier or weighted feel. Additional characteristics are that the toy figure material is easily paintable and significantly more resistant to dyes(co!or migration).
- the molded part is formed using a mixture of ABS and barium sulfate.
- the mixture of ABS and barium sulfate can be about 20 - 80 weight percent barium sulfate and about 20 - 80 weight percent ABS.
- the mixture includes about 30 - 70 weight percent barium sulfate and about 30 - 70 weight percent ABS.
- the mixture includes about 40 - 60 weight percent barium sulfate and about 40 - 60 weight percent ABS.
- the mixture may include about 35 - 55 weight percent barium sulfate and about 45 - 65 weight percent ABS.

- a flow additive is added to the mixture of ABS and barium sulfate.
- FIG. 1 illustrates a perspective view of an embodiment of a figure according to the invention.
- FIG. 2 illustrates a cross-sectional plan view of a portion of a component of the figure illustrated in FIG. 1 taken along the line "2-2."
- FIG. 3 illustrates a cross-sectional plan view of another portion of the component of the figure illustrated in FIG. 1 taken along the line "3-3.”
- FIG. 1 The term "figure" as used herein includes all types of toy figures and dolls.
- one type of figure or doll is a collector or fashion doll which, as described below, typically has different properties than conventional toy figures or dolls.
- the toy figure 10 includes a torso 12, arms 14 and 16, legs 18 and 20, and a head 22.
- one or more of the components of the toy figure 10 are solid pieces of material.
- the thickness of the different parts or components of the toy figure 10 vary.
- the torso has a thickness that varies along the length of the torso.
- each of the arms 14 and 16 and each of the legs 18 and 20 can vary in thickness as well.
- the solid construction and the varying thickness of the parts of the toy figure 10 often present molding challenges.
- the components of the toy figure 10 can be referred to alternatively as thick-walled components.
- leg 18 of toy figure 10 a cross-sectional view of leg 18 of toy figure 10 is illustrated.
- the leg 18 has a first dimension "d l " extending from the front of the leg 18 to the back of the leg 18.
- the leg 18 has a second dimension "d2" extending from one side of the leg 18 to the other side of the leg 18.
- the particular dimensions "d l" and “d2" at this location of the leg 18 can vary.
- FIG. 3 another cross-sectional view of leg 18 of toy figure 10 is illustrated.
- the cross-section illustrated in FIG. 3 is taken at a location that is lower on the leg 18 than the cross-section illustrated in FIG. 2.
- the leg 18 has a third dimension "d3" extending along the same direction as dimension "d l .”
- the leg 18 has a fourth dimension "d4" extending along the same direction as dimension "d2.”
- dimension "d3" is shorter than dimension "dl”
- dimension "d4" is shorter than dimension "d2.”
- the leg 18 is solid at both cross-sectional locations.
- the leg 18 is a solid, molded piece of material.
- Leg 20 and arms 14 and 16 are also solid, molded pieces of material.
- one or more parts of the figure are molded using an injection molding technique.
- the material to be molded needs to have a viscosity that enables it to fill all of the cavities of the mold.
- molding involves forming parts that have an even wall thickness, which the parts of the toy figure 10 do not have.
- Polymers are not good thermal conductors and are materials with high rates of shrinkage and coefficients of thermal expansion. These characteristics mean that when there are large differences in wall thickness within the component being molded, then some parts of the component will cool more and less quickly than other areas of different thickness. This effect will lead to sink/distortion and certainly different temperatures within the component at the point of ejection from the mold.
- One solution to control the sink/distortion is called "packing" which involves the injection of material after the mold is full. This solution requires that the gate point be large enough to prevent premature freezing while the "packing" continues.
- the molding material is a mixture of two materials, one viscoelastic and the other essentially solid particles suspended in the viscoelastic material, there is a tendency for the mixture to separate due to high stresses required to make the material flow when the mixture is force through channels. Since the stress is highest at the boundary between the material and the wall of the mold channels, combined with the fact that the mold is cooler than the melt mixture, the tendency is to cause the surface of the melt to fracture. This is then "frozen" at the surface since the melt is in contact with a cooled mold. This causes aesthetic defects to appear on the surface of the molded part, particularly at high stress points.
- melt viscosity can be reduced by using high MFI grade resins and raising melt temperature as much as possible.
- heated molds can be used to reduce the rate of cooling and to slightly reduce the stress at the boundary layer.
- the toy figure 10 is a collector-type doll in that it is intended to have characteristics and features that are not normally found in dolls or figures with molded parts.
- the difference in characteristics and features between conventional dolls formed of basic molded plastic parts and the toy figure 10 is based on the particular material that is used to form the toy figure 10.
- the toy figure 10 has several characteristics or features that are desirable.
- One characteristic or feature is the aesthetic appearance of the figure. It is desirable that the figure has a "porcelain-like" aesthetic in that the figure appears to look like it is made of porcelain. This porcelain aesthetic is neither expected nor obtained from conventional molded plastic parts.
- Another characteristic or feature of the toy figure 10 is how the surface of the figure feels to a user. It is desirable that the figure has a surface that feels cold to the touch, which is another similarity to porcelain material. This cold sensation is also not expected from toy figures that are made using conventional molded plastic parts.
- Another characteristic or feature of the toy figure 10 is the relative weight of the toy figure 10.
- the toy figure 10 weighs more than a toy figure that is formed of conventional plastic parts, which as noted above, are often hollow and relatively light in weight.
- the specific gravity of the molded components of the toy figure 10 is greater than the specific gravity of a conventional plastic figure. It is desirable that the figure has a weight that is slightly heavier than a conventional doll figure. This increased weight provides the toy figure 10 with a stronger, more substantial feeling which is characteristic of porcelain material.
- the molded material has a desired range of specific gravity.
- the toy figure 10 be paintable.
- the molded material be easily paintable so that color can be added to the toy figure 10.
- a primer material is needed to be applied initially to a toy figure to facilitate the painting of the toy figure with the desired colors.
- the material used for toy figure 10 can be painted directly, which results in cost and time savings.
- the composition of the molded portions of the toy figure 10 has better properties, such as strength and durability, than an actual porcelain material.
- the improved properties allow for a more versatile usage of the toy figure 10.
- the toy figure 10 is formed using a composition that includes a resin.
- the resin is acrylonitrile butadiene styrene, referred to herein as ABS, which is a thermoplastic material.
- ABS is a copolymer and is comprised of polymerized styrene and acrylonitrile with polybutadiene.
- the relative proportions of the components of ABS can vary depending on the particular application or use. In one exemplary implementation, the proportions of the components of ABS can range from about 15 - 35 percent weight acrylonitrile, about 5 - 30 percent weight butadiene, and about 40 - 60 percent weight styrene. Molded materials that include ABS are easily paintable.
- the use of a resin such as ABS in a molded component requires a glass fiber or filler in the resin compound due to the fragility and brittleness of molded ABS material.
- the composition that is used to mold the parts of the toy figure 10 does not include any glass filler material.
- the lack of glass filler material is acceptable for toy figure 10 because structural, machineable, and high tensile strength are not needed as other characteristics and features, such as aesthetic and feel, are desired for the toy figure 10 as discussed in greater detail below.
- barium sulfate (BaS0 4 > is added to the ABS resin as a filler.
- the quantity of barium sulfate that is added to the ABS material changes the properties of the overall mixture. For example, as the quantity of barium sulfate added to ABS increases, the resulting composition becomes drier.
- the composition to be molded needs to be able to adequately fill the cavities of the mold. Accordingly, if the mixture is too dry, then the mixture will likely not adequately flow throughout the mold, thereby resulting in defects in the molded toy figure 10.
- ABS was loaded with 30 - 70 weight percent barium sulfate.
- additional ABS can be added to the initial mixture of ABS and barium sulfate.
- the resulting mixture can have about 30 - 50 weight percent barium sulfate and 50 - 70 weight percent ABS.
- the initial mixture can be formed of 20 - 80 weight percent barium sulfate added to 20 - 80 weight percent ABS.
- the initial mixture for the toy figure 10 may include about 40 - 60 weight percent barium sulfate and about 40 - 60 weight percent ABS.
- the composition may include about 35 - 55 weight percent barium sulfate and about 45 - 65 weight percent ABS.
- the main components of the material used to form the body of the toy figure 10 are ABS and barium sulfate. In addition or alternatively, the material can also be used to form the eyes of the doll or toy figure 10 or a different figure as well.
- a colorant can be added to the main component mixture.
- the mixture may include about 0.5 - 5.0 percent weight of the colorant.
- the colorant can be a standard colorant that is selected from a standard color reference chart or samples and that can be obtained from available plastic colorant systems.
- a flow modifier is added to the main component mixture.
- the flow modifier is added to reduce gate blush and flow marks from the molded components.
- the mixture may include about 0.5 - 5.0 percent weight of the flow modifier as well.
- the composition includes about 40 - 45 weight percent barium sulfate, about 50 weight percent ABS, and the remainder is viscosity modifiers, flow agents, and pigments.
- the specific gravity of the toy figure 10 can vary depending on the particular composition that is molded. In one embodiment, the specific gravity of the toy figure is about 1 .50 - 1 .60. The higher the specific gravity represents a relatively heavier toy figure 10. Initially, ABS has a specific gravity of about 1 .50 - 1 .52. The specific gravity of the composition increases as the amount of barium sulfate is increased. However, as mentioned above, the amount of barium sulfate in the mixture affects the moldability of the mixture and the characteristics of the molded pieces. Regarding the moldability, increased amounts of the filler results in a drier product, which is more difficult to mold.
- the specific gravity of the toy figure can be lowered such that a specific gravity of about 1.44 is obtained.
- the desired mixture of ABS and barium sulfate (and, if included, a colorant and/or a flow agent) is molded using an injection molding process.
- the molded component can be painted.
- This molded component can be painted without a primer due to the ABS being used.
- this molded component allows solvent bonding using common industrial solvents such as MEK (also known as butanone) and methylene chloride.
- MEK also known as butanone
- methylene chloride methylene chloride
- this molded component has significantly improved color migration absorption properties as compared to conventional materials.
- molded components including ABS do not have any color transfer from dyes used in polyester fabrics or other materials.
- the toy figure can be a single piece of material and formed using a single molded piece of material.
