  • Patent number: 9370912
    Abstract: By creating a slurry of biodegradable material, forming it in a mold under a vacuum, a channel may be created in the lid which can be release-ably connected to a traditional rolled lip coffee cup, among other common liquid holding vessels but be made out of biodegradable material. The resulting lid may be elastic enough such that the lid will give to allow a complementary cup to fit into the channel to create a seal between the cup and the lids. It also will be firm enough to withstand the weight and pressure of the liquid inside the container and from pressure from consumers while using the container. The lid also may be sufficiently heat resistant to withstand desired temperatures and liquid exposure for a time long enough for a consumer to enjoy the contents of the container but also be biodegradable.

The resin is sucked from the space through the plate (56). According to such composite material manufacturing method, a defect, which occurs during fibers are impregnated with resin, can be repaired before the resin is cured without causing disorder and damage in the fibers. In a composite material formed from one repaired in the above way, the repaired portion is strong, namely, there is no strength deterioration due to repair after curing, and thus, the material is preferred as compared with a composite material which is repaired after resin is cured.

  • Patent number: 7858015
    Abstract: Methods for making a molded beverage container insulator from a slurry including water and a polysaccharide by presenting at least one male mold, which may have an elliptical cross section, therein and causing a portion of the slurry to temporarily adhere to the at least one mold. After a suitable period of time, removing the mold from the slurry and then removing the insulator. At such time, and particularly if the mold is not characterized as elliptical in cross section, the insulator is subject to bidirectional compression in order to collapse the same. Opposing hinge elements may be formed in the insulator, either at the time of molding or subsequently, to localize stresses resulting from the collapsing of the insulator. The resulting insulator is fully recyclable/compostable and possesses a constricting bias to mitigate container slip issues.

  • Patent number: 7780885
    Abstract: The invention relates to a high pressure casting method for producing articles of sanitaryware and to a machine implementing the method. The method of type “A” comprises the steps of forming the thickness of the sanitaryware article, emptying the excess slip out of the mould and consolidating the article, all these steps being performed at a constant pressure equal in value to the maximum pressure of the step in which the thickness of the article is formed. In the method of type “B”, the steps of emptying out the excess slip and consolidating the sanitaryware article (14) are performed at a pressure equal to 75% of the maximum pressure of thickness formation. The casting machine comprises a discharge device for draining out the excess slip through a calibrated valve that enables the slip to be discharged without decreasing the pressure in the mould.

  • Patent number: 7074302
    Abstract: A fibrous panel is molded in two or more progressively formed mold members each comprising a porous support plate to which a plurality of rigid mold pieces are affixed. The mold pieces are truncated 3D tapered structures, and are arranged on the support plate in a regular array so that an intersecting grid or lattice of channels is defined between them. A fiber stock is poured into a first mold member and the stock is compressed and dewatered to form a panel. The panel is removed from the first mold member and placed into a second mold member having narrower and shallower channels whose side walls are more upright than those of the first mold member. The panel is further compressed and dewatered in the second mold member, and is densified in both the vertical and lateral directions by virtue of the progressive formation of the mold members.
