  • Publication number: 20200239174
    Abstract: A synthetic resin multilayer bottle includes an outer shell bottle, which can restore an original shape thereof in response to deformation attributable to pressing, an inner container body which deforms when pressed, and an air channel through which outside air is introduced between the outer shell bottle and the inner container body. The synthetic resin multilayer bottle has oxygen permeability such that, after the inner container body is fully filled with distilled water from which dissolved oxygen has been removed, an inner opening part is sealed, and the distilled water is allowed to stand for 60 days at a temperature of 20° C. while keeping the air channel between the outer shell bottle and the inner container body open, the amount of dissolved oxygen in the distilled water is 3 ppm or less. Such bottle prevents a liquid seasoning containing soy sauce from deteriorating due to oxygen in outside air.

  • Patent number: 9987774
    Abstract: A molding apparatus (1) includes: a servomotor (11) for pressing a resin component (W) by moving an upper mold (MU) in a direction in which the upper mold (MU) is made close to a lower mold (ML); servomotors (12a and 13a) each of which retains X-coordinate and Y-coordinate positions of the lower mold (ML); and a position detection section (41) which determines whether or not the resin component which is sandwiched between the upper mold and the lower mold has been cured, the servomotors each terminating the retention of the lower mold when the resin component has been cured. This makes it possible to obtain a molded product while preventing positional displacement caused by a decrease in volume of a resin which is being cured.

  • Patent number: 9452554
    Abstract: A molded product manufacturing method and a molded product manufacturing apparatus are realized, each of which has improved quality and productivity of a molded product. A pressure to be applied to an upper mold (ML) and a lower mold (ML) is reduced in stages during a process from a start of decrease in internal temperatures of the upper mold (ML) and the lower mold (ML) to a complete mold-release of a resin component (W). This prevents an excessive load from being applied to the resin component (W) which has been molded but has not been mold-released.

  • Patent number: 9427919
    Abstract: When an optical element is produced by sandwiching a resin between a pair of molds, the resin is cured while a mold is kept in contact with the resin until the temperature of the resin reaches a gel point. Throughout the process, a load cell monitors pressure exerted to the mold. After detection of a state in which the pressure exerted to the mold is a negative pressure, the resin is cured while the position of the mold is controlled so that the pressure exerted to the mold is increased to a predetermined positive pressure and thereafter the positive pressure is maintained.

  • Patent number: 8815129
    Abstract: In order to realize a device and a method each capable of forming a lens with high accuracy and low costs, a lens forming device of the present invention includes a metal mold, an insulating substrate, a stage, a power source, a switch, and a UV radiating device. Dielectric resin is supplied onto the insulating substrate and a transfer surface of the metal mold is pressed to the dielectric resin so as to transfer a lens shape to the dielectric resin. At that time, the power source applies a voltage on the metal mold to generate an electric field between the metal mold and the insulating substrate so that an electrostatic attraction causes the dielectric resin to be attracted toward the transfer surface of the metal mold while the top of the dielectric resin has a sharp cuspate shape. Consequently, bubbles are less likely to be invade between the transfer surface and the dielectric resin, allowing transferring a highly accurate lens shape to the dielectric resin.
