A two-color molded article includes a first resin part, and a second resin part in contact with the first resin part so as to at least partially overlap the first resin part. The second resin part includes a single layer region provided between a first region and a second region and provided in a penetrating portion formed between a first portion and a second portion. The single layer region has a joint portion in contact with a bent portion. The joint portion is formed in a convex shape with respect to the bent portion.

[Problem] To provide: a composite container which can be given various functions and characteristics; a method for producing such composite container; a preform; and a composite preform.

[Solution] A composite container according to the present invention includes: a container body which is made of a plastic material; and a plastic member disposed on the outer surface of the container body, wherein the container body and the plastic member are integrally inflated by means of blow molding, and wherein the plastic member includes a colored layer and/or a print layer where a print is made.

Disclosed are a gradient resin, a preparation method therefor and the use thereof. The gradient resin of the present application is formed by fusing different layers with color transition changes, wherein the color transition change between the two adjacent layers is in the range of 0.1% to 5 20%. The gradient resin is composed of, by mass percentage, 98%-99.99% of a resin powder and 0.01%-2% of a pigment.

The present disclosure is related to a method for manufacturing slabs of artificial agglomerated stone comprising: depositing a first layer (1.1) of a first mixture (M.sub.1) onto a surface (2), wherein the first layer having a first thickness h.sub.1, creating at least one cavity (3), having a width w.sub.i and a length L.sub.i, in the first layer (1.1) of first mixture (M.sub.1), depositing a second mixture (M.sub.2) into the at least one cavity (3) of the first layer (1.1), forming a second layer (1.2) by depositing the first and second mixtures, and the second layer having a second thickness h.sub.2, compacting and hardening the second layer (1.2), wherein the method further comprises after step c) and before step d), inserting a first tool (5) at least partially into the second thickness h.sub.2 of the second layer (1.2), and actuating the first tool (5) wherein the first tool (5) is configured to stir the first wall portion (4.1) while not stirring the second wall portion (4.2).

In an illustrative implementation of this invention, a 3D object comprises substrate layers infiltrated by a hardened material. The 3D object is fabricated by a method comprising the following steps: Position powder on all or part of a substrate layer. Repeat this step for the remaining substrate layers. Transform the powder into a substance that flows and subsequently hardens into the hardened material. The hardened material solidifies in a spatial pattern that infiltrates positive regions in the substrate layers and does not infiltrate negative regions in the substrate layers.

Multicolored flexible wearables include a first portion having a first flexible polymer forming a toroid and including colorant(s), an exposed first outer surface, an exposed second outer surface, and a recess in the first outer surface not reaching the second outer surface. A second portion formed of a second flexible polymer fills a majority of the recess and includes colorant(s). The first and second flexible polymers have different colors and are permanently bonded together. Precious material particles may be disposed within the first and/or second flexible polymers. One or more of the colorants may have a color matching a color of the precious material particles. One method of bonding the portions includes depositing a liquid second portion into the recess and then curing it. Another method includes depositing a solid second portion into the recess and then curing a liquid layer of polymer between the first portion and second portion.

The present invention provides a method of producing a topping hanger comprising: (a) inspecting raw materials; (b) calculating a formula; (c) mixing uniformly; (d) dehumidifying the raw materials; (e) injection molding a colored mixed body: introducing the dehumidified raw materials into an injection molding machine at temperature 200-350° C., and the colored mixed body being produced by injecting molding after adjusting parameters of molds; (f) injection molding a transparent exterior body: a transparent PET and acrylics being formed of the transparent exterior body outside of the colored mixed body by injection molding at temperature 200-350° C.; and (g) packing the products. The transparent exterior body fully coats with the colored mixed body via injection molding, and this feature effectively enhances quality and visual effect, and chemical and color stability of the products, and reduces the cost. The present invention reduces damage during objects with colors contacting human.
