A container with cap provided with a knock cam mechanism having an uncomplicated structure employing a small number of parts, enabling the cap to be securely attached to and detached from the container body. The cap has a housing in which a plurality of grooves alternating with ribs are formed in an inner circumferential surface thereof at equiangular intervals around a cylindrical axis, and inside the housing are disposed a push-button plunger having protrusions formed on the outer peripheral surface that slide along inside the grooves, a ratchet having sloped protrusions on the outer circumference, an inner lid having tabs on the peripheral wall, an elastic member for urging the ratchet upward, and a container body in which a locking portion is formed on the outer circumference of a neck of the container body.

Container with cap

A cosmetic container which is capable of stabilizing an action of a hinge portion is provided with a single pivot shaft member, and improving opening and closing functions of a lid body. Included are: a container main body configured to contain a cosmetic; a lid body turnably provided to the container main body and capable of opening and closing the container main body; and a first pivot support member and a second pivot support mechanism disposed on a pivot axis about which the lid body turns, and causing the container main body to turnably support the lid body. The first pivot support member includes: a compression coil spring located between the container main body and the lid body; and a lock member and a pivot member. The second pivot support mechanism includes fan-shaped recessed and projecting portions and a shaft portion of the second pivot support member.

The present invention provides a polymer-metal complex composite, which comprises a block copolymer capable of serving as a constituent member of a polymeric micelle and a metal complex having MRI contrast ability, accumulates in a tumor-specific manner, achieves high image contrast even in a small amount, and has reduced side effects and a long retention time in blood. The polymer-metal complex composite of the present invention comprises a block copolymer (A) represented by general formula (a) and a metal complex (B) having MRI contrast ability, wherein the composite comprises a structure in which a carboxyl anion of poly(carbo) in the copolymer (A) is attached to the metal complex (B) via a metal atom (M).

This invention provides organic-inorganic hybrid particles containing as the essential components a block copolymer comprising an uncharged hydrophilic polymer chain segment and a polymer chain segment containing a repeated structural unit having a carboxylate ion group at its side chain; calcium ion (Ca), phosphate ion (PO) or carbonate ion (CO), or a mixture of these anions; and a contrast agent. The particles provide, in particular, carriers for stably delivering an MRI contrast agent to a target site.

[Problem to be solved] To provide a compact case built-in with a hinge unit that can be easily assembled while reducing manufacturing costs of parts. [Solving Means] A compact casewith a lid bodyconnected, in an openable and closable manner, via a hinge using at least one or more hinge unit, to a back end of a flat box shaped container body, the compact case includes a frame bodyof a plate-like member having a flat shape along a peripheral shape of an upper opening of the container body, the back end of the container body is formed with a hinge storing sectionfor storing a case section of the hinge unit so that a shaft section of the hinge unit is protruded, a back end of the lid body is formed with a receiving holein which the shaft section of the hinge unit is to be inserted, the frame body is attached to the container body so as to cover up the hinge storing section, the shaft section of the hinge unit is inserted in the receiving hole in a state the case section of the hinge unit is fixed to the container body, and the container body and the lid body are connected in an openable and closable manner.

Compact case built-in with hinge unit and method of manufacturing compact case built-in with hinge unit

A cosmetic case containing a replaceable inner case which can be easily removed or inserted, and which is specifically structure to maintain the cosmetic material contained therein in a fresh and useable condition. The invention is comprised of an outer case with a floor area and inner peripheral wall defining a space for an inner container, an outer cover attached by a hinge to the outer case, a main latch employed to hold the outer cover closed, a replaceable inner container providing a cosmetic holding space, an inner container cover capable of opening or closing over the cosmetic holding space, and a sub-latch employed to hold the inner cover closed against the inner container. The inner case is equipped with a hinge part to allow opening and closing of the inner cover, the hinge part fitting into a cutout section on the peripheral wall of the outer case so as to expose the hinge and thus allow wide angle opening of the inner case cover. Inner case installation is aided by small protruding ribs formed within the outer case with the purpose of indexing and securing the inner case. An orifice is provided in the floor of the main case to allow the inner case to be pushed up and removed by finger pressure applied from below. The cosmetic case is characterized by a push-type latch mechanism which opens the outer and inner case covers simultaneously in one movement, an effective sealing mechanism between the inner case and cover, and specific inner cover structures to inhibit the fall of condensation droplets onto the cosmetic surface.
