A container for packaging and dispensing of a solid cosmetic or care product. The container comprises a hollow base and a cap for holding the solid product. The cap is rotatably mounted on the hollow base of the container to present the solid product to a surface of application including skin, face, lip, eyelashes, hair, nail etc.

A flat-pressing manufacturing method of a bionic adhesive structure based on a micro through-hole nickel-based mold is disclosed. The method includes the following steps: preparing a nickel-based mold with a micro through-hole array; placing the nickel-based mold on an elastic pad in a magnetic mold closing system; coating a liquid prepolymer uniformly on a backing, and placing a side of the backing coated with the liquid prepolymer on the nickel-based mold, covering a sealing diaphragm on the backing to separate a cavity into an upper chamber and a lower chamber, and performing a vacuum treatment on the lower chamber and an inflation treatment on the upper chamber to apply a uniform pressure on the backing layer and achieve a full filling of prepolymers with different viscosities; and after the filling is completed, curing and demolding to obtain the bionic adhesive structure.

Systems and methods for protecting a user from external contamination with a mask. Exemplary embodiments may include a mask including an open threaded portion couplable to a filter; one or more extrusions on a front of the unibody mask to mount straps to the unibody mask; wherein the mask is made of silicone, and wherein the unibody mask presses against a face such that the unibody mask seals an interior of the unibody mask from an exterior of the unibody mask.

A method for manufacturing a molded product with fine structure includes steps of, in a temperature-controlled stamper mold provided with a fine structure including a concavo-convex pattern having a width of 10 nm to 1 μm, forming a thermoplastic molten polymer layer to be in contact with the fine structure 20 of the stamper mold having been kept at a predetermined temperature and holding the thermoplastic molten polymer layer for a predetermined time so as to transfer the fine structure of the stamper mold to the thermoplastic molten polymer layer under gravity.

According to one embodiment, a gripping tool includes a gripper. The gripper is flexible and includes a first portion contacting a workpiece, a second portion opposing the first portion, and a granular material provided between the first portion and the second portion. The first portion includes a concave portion and a convex portion. The concave portion is recessed in a first direction. The first direction is from the first portion toward the second portion. The convex portion is provided around the concave portion and protrudes in a second direction. The second direction is the reverse of the first direction. The concave portion has a groove having a ring configuration recessed outward from a center of the gripper.

The application relates to an adjustable moulding tool and corresponding model production method, including following process steps: moving rods towards the said chamber through the said chamber's holey surfaces manually or via mechanisms in increments numbers of which are calculated through computer programs or manually, after the formation of the emptiness in the shape of the model, pouring of the material in a manner to fill the emptiness, heating and cooling or applying other processes in accordance with the characteristic of the poured material to enable that material takes the desired monolithic shape, after material takes the form of the model monolithically, making the casting chamber free of the rods, which have initially been moved towards the casting chamber with the purpose of the formation of the emptiness, by moving the rods in the reverse directions and taking out the produced model through an openable surface of the said chamber.

Provided is a Fresnel lens which has excellent heat resistance and which can covert light even from a poor-quality semiconductor light sources into uniform, high-quality light and can disperse the resulting light without lowering the central illuminance. The Fresnel lens according to the present invention includes two or more sawtooth prisms in a surface thereof and is made of a cured product of a curable composition containing an epoxy compound (A). Of the sawtooth prisms, a sawtooth prism having a longest inclined side in a cross section has a roughened surface, where the cross section is given by cutting the Fresnel lens in a plane which passes through the center of the Fresnel lens and which is perpendicular to a reference plane of the Fresnel lens.

Embodiments of the invention are directed to an automated crayon-molding device comprising a crayon-receiving member, an automated heating element, a crayon-melting chamber that is heated to a melting temperature by the automated heating element, and at least one mold. The crayon-receiving member receives the crayon at one end and has a closure mechanism at another held, preventing the crayon from entering in the crayon-melting chamber until it reaches a melting temperature. Once the inside of the crayon-melting chamber, the crayon melts and drips into a mold configured to receive melted wax. Embodiments of the invention also include a method for assembling an automated crayon-molding device and a system for molding crayons that includes a crayon-receiving member, an automated heating element, a crayon-melting chamber, a drawer positioned underneath the crayon-melting chamber, and at least one mold.
