Abstract: A multiwell instrument includes a vessel having an inside; a plurality of culture plates arranged in the inside of the vessel, each individual one of the plurality of culture plates having an inside in which material to be examined can be stored; and filters disposed inside the respective culture plates to partition the insides of the respective culture plates into at least two wells which are horizontally adjacent.

Abstract: The present invention relates to a culture vessel which can be broadly applied to culture, regeneration, manufacture, observation and the like of targets such as cells, organs, and microorganisms. In the culture vessel of the present invention, a first vessel 10 and a second vessel 20 each being a close-bottom, open-top vessel are provided. In the first vessel 10 and the second vessel 20, a sideways-facing opening 12 and a sideways-facing opening 22 are formed. The opening 12 and the opening 22 communicate in a watertight manner when the openings 12, 22 are connected face to face.

Abstract: A multiwell instrument capable of extending a use method in a conventional microtiter plate is provided. A multiwell instrument 1 includes a plurality of wells 3, boundary portions 4 respectively provided between the respective wells and adjacent wells, and a filter 6 provided in at least one boundary portion of the boundary portions 4.

Abstract: A packaging container has an improved degree of freedom in the shapes of a container body and a cap, and prevents required turning force from being excessively large. The packaging container includes a container body having an upward-facing mouth, and a cap for closing the mouth. The container body has a plurality of axial drive ribs and a circumferential locking groove formed on an outer perimeter of the mouth. The cap has protruding rib portions on an inner surface side and locking claws to elastically lock into the locking groove, extended down from a top surface thereof.

Abstract: A safety cap including a screw-type inner cap detachably mounted on a container mouth; and an outer cap that is combined with the inner cap so as to be rotatable relative to the inner cap. Each of the inner cap and the outer cap has a plurality of engaging protuberances. The engaging protuberances of the inner cap and the engaging protuberances of the outer cap are engaged with each other and rotate the inner cap when the outer cap is rotated while being pressed toward the inner cap. Each of the engaging protuberances has a vertical part that is engaged when the outer cap is rotated in a closing direction and an inclined part that is engaged when the outer cap is rotated in an opening direction. The inclined part has a steeply inclined part and a gently inclined part that is continuous with the steeply inclined part.

Abstract: A fluid container according to the present invention includes a container body having upper and lower openings, and further having a shoulder member and a side wall which extend between the upper and lower openings. The fluid container also includes a spacer abutting on the shoulder member of the container body, and a slidable valve slidably moving along an inner surface of the side wall of the container body in a hermetically sealed manner. The slidable valve defines a container space for holding fluid, in conjunction with the side wall of the container body. Further, a bottom cover is provided for covering across the lower opening of the container body. The spacer and the slidable valve include a spacer surface and a valve surface, respectively, which oppose to each other and are inclined at tilt angles between 5 and 30 degrees relative to a horizontal surface.

Abstract: An eye drops container including a container body filled with a drug solution along with a pressurized gas and including a valve mechanism discharging a fixed amount of drug solution; a nozzle member coupled with a stem for open operation of the valve mechanism and including a drug solution drop nozzle; an operating member including an operating piece and attached to the container body; a guide member contained in the operating member and guiding the nozzle member in the axial direction; and a ball contained in the guide member. The nozzle member includes an outer flange for suspending a skirt on the lower surface thereof; the guide member includes a ring-like bottom groove into which the forward end of the skirt enters; and the ball falls into the bottom groove in an upright state to block the open operation of the valve mechanism, and falls onto the outer flange in an inverted state to permit the open operation of the valve mechanism.

Abstract: A nozzle includes a top portion projecting in the same direction as an opening of a container, and a plurality of liquid-medicine passages formed at an outer periphery of the top portion. When the container is inclined, a liquid medicine in the container leaks out therefrom via orifices of the individual liquid-medicine passages communicated with the opening of the container, so as to form a droplet on an outside surface of the top portion, whereby the liquid medicine is applied in a droplet.
