Abstract: A management server, a service server, and a plurality of user terminals are connected to each other via a network so as to be capable of transmitting and receiving data. The management server includes a user information storage unit that stores user identification information for identifying users belonging to a group, and an identification information notification processor that, each time a service to be provided to the users of the group is newly added, transmits the user identification information of the plurality of users belonging to the group to the service server by cryptographic communication, corresponding to the newly added service. The service server includes a service information storage unit for storing the user identification information of the plurality of users corresponding to the service, received from the identification information notification processor.

Abstract: A sealed container material having a deoxidation function comprises a metallic base material reactive with oxygen and a hydrophilic coating layer of water-soluble polymer such as hydroxyethyl cellulose formed on the surface of the metallic base material. An oxygen- and moisture-permeable coating layer composed of a polymethylpentene resin may further be provided on the hydrophilic coating layer. The material exhibits an excellent oxygen absorbing ability and is thus suited as a material for sealed containers, such as cans, bottles, capsules, etc., for encasing food, drink, chemicals, and medical drugs and storing them over a long period of time without denaturation or deterioration.

Abstract: A sealed container material having a deoxidation function comprises a metallic base material reactive with oxygen and a hydrophilic coating layer of water-soluble polymer such as hydroxyethyl cellulose formed on the surface of the metallic base material. An oxygen- and moisture-permeable coating layer composed of a silicone resin or an olefin resin may further be provided on the hydrophilic coating layer. The material exhibits an excellent oxygen absorbing ability and is thus suited as a material for sealed containers, such as cans, bottles, capsules, etc., for encasing food, drink, chemicals, and medical drugs and storing them over a long period of time without denaturation or deterioration.

Abstract: A rotating mechanism attachable to the bottom of a container comprising:(A) a base member composed of (i) a circular side wall provided with means for preventing the base member from becoming detached from an attachment member and (ii) a base plate provided at the bottom portion of the circular side wall; and(B) the attachment members composed of (i) a peripheral support portion having an outer diameter smaller than an inner diameter of the circular side wall and (ii) an attachment plate, the bottom portion of the circular side wall of the base member being connected to the peripheral support portion at connecting portions thereof in such a manner that both portions are readily mechanically separable from each others.

Abstract: A vessel with a tabular, flexible handle. The body of the vessel is integrally provided with upper and lower mounts which serve to attach the handle to the vessel. A means for preventing the upper end of the handle from downwardly slipping out of the upper mount and a means for preventing the lower end of the handle from upwardly slipping out of the lower mount are formed integrally with the handle. The lower end of the tubular handle downwardly passes through the upper mount and then through the lower mount. Since the total length of the handle is greater than the distance between the upper edge of the upper mount and the lower edge of the lower mount, the handle can be picked out so as to become bow-shaped, in which position the means for preventing the upper and lower ends of the handle from slipping out of the upper and lower mounts engage with the upper and lower mounts and thereby secure the handle to the vessel.
