  • Publication number: 20200360191
    Abstract: In a production method of an elastic composite sheet, the elastic member does not break when the elastic member, in a stretched state, is bonded to a base material sheet; an elastic composite sheet and a disposable wearable article use the elastic composite sheet. A strip-shaped or string-shaped elastic member composed mainly of a thermoplastic elastic resin is stretched in the longitudinal direction of the elastic member. The stretched elastic member is placed over a first base material sheet such that the main surface of the first base material sheet contacts the elastic member. In this state, the elastic member and the first base material sheet are bonded in a first position that overlaps the elastic member seen from a direction perpendicular to the main surface of the first base material sheet and that is away from the edges of the elastic member.

  • Patent number: 9808401
    Abstract: Provided is an exposure-preventing cap of a novel and simple structure that, by being mounted on a vial, can more reliably inhibit leaking of drug solution to an outside when pulling out and collecting drug solution in a syringe from the vial. An exposure-preventing cap, which is mounted on a mouth of a vial sealed with a rubber stopper, wherein a puncturing hole is formed in a center part of a cap-shaped housing that is attached to a mouth of the vial, and a rubber membrane is arranged at the puncturing hole so as to form an internal space between facing surfaces of the rubber membrane and the rubber stopper. The rubber membrane has a dome shape that is convex facing the rubber stopper.
