  • Patent number: 7404814
    Abstract: An infusion vessel has a vessel body having an internal cavity to serve as an infusion medium space, a cylindrical discharge mouth continuing from a lower portion of the vessel body, a medicine chamber disposed in the discharge mouth and kept airtight against ambient air, and a separator intervening between the infusion medium space and the medicine chamber so as to keep the space in a liquid-tight state against the holder. The separator is subject to displacement, rotation or deformation such as to bring the infusion medium space into communication with the medicine chamber, so that the infusion vessel can be made ready for use by conducting a simple operation to mix the medicine with the infusion medium that have been separated from each other within the vessel during its normal state before use.

  • Patent number: 7114636
    Abstract: A discharging container including a laminated bottle having a delaminatable layer is designed such that it can be manufactured through reduced processing steps. The present discharging container has the ambient air inlet and the ventilation hole. The inlet is formed solely in the outer layer and always kept open. The ventilation hole is formed solely in the outer layer and normally closed with the closing member or the inner layer. The inlet may be formed in a peripheral wall of the outer layer's body part and the ventilation hole may be formed in the mouth part of the bottle.

  • Patent number: 6581803
    Abstract: A discharging container having outer and inner layers with an ambient air inlet formed solely in the outer layer without a valve. The inlet has an opening smaller than the opening of a discharging outlet mouth formed in a cap, so that the outer layer's body part may be squeezed to compress the air between the inner and outer layers, whereby the compressed air depresses the inner layer inwardly and radially to exude a liquid content outwards through the discharging outlet.

  • Patent number: 6536586
    Abstract: A combination vessel is capable of carrying out temporary fastening while always bringing down a ring portion subsequently to breakage of a bridge part during an opening operation. A cap portion and a ring portion of a cap type sealing tool are coupled to each other through a bridge part. Through breakage of the bridge part during opening of the cap portion, the ring portion is pulled down while a sliding protrusion on an internal wall in a lower stage area of the ring portion always contacts by pressure an upward spread zone on an external wall of a neck zone of a bottle portion.

  • Publication number: 20010019022
    Abstract: To develop a combination vessel capable of carrying out temporary fastening while always bringing down a ring portion subsequently to breakage of a bridge part during opening. A cap portion (11) and a ring portion (12) in a cap type sealing tool (1) are coupled to each other through a bridge part (13). Through breakage of the bridge part during opening, the ring portion is pulled down while a sliding protrusion (12uc) on an internal wall in a lower stage area of the ring portion always interposes an upward spread zone (2nx) on an external wall of a neck zone of a bottle portion (2) by pressure. In addition, a vertical convex to block the opening turn (12rc) provided on an inner periphery of the ring portion and a vertical convex (2rc) to block opening turn provided on the external wall (2rz) of the neck zone of the bottle portion do not block attachment of the cap type sealing tool (1) but blocks accompanied rotation of the ring portion during the opening of the cap portion, thereby breaking the bridge part.

  • Patent number: 5984123
    Abstract: A packaging container having a container body and a lid unit which is undetachably mounted on the container body. The container body has a neck portion provided with an opening. An external thread cut in the outer periphery of the neck portion, and a lid mounting portion is provided below the external thread. The lid unit has a lid body and a fitting member. The lid body is provided with an internal thread engageable with the external thread of the container body, and has a function of hermetically sealing the opening of the container body. The fitting member is rotatably fitted around the lid mounting portion of the container body, but vertical movement of the fitting member is restricted within a predetermined range. The fitting member is held undetachable from the lid mounting portion by a collar of the container body.
