Abstract: The present invention is related to a cap assembly which is put over a mouth of a bottle and a method for capping of capping the cap assembly to a bottle, and includes a function that makes it possible to open an inner stopper only by operating a cap when removing the cap initially, and makes attaching thereof to the bottle easy. There are included an inner stopper 40 and a cap 50, which respectively include a male screw thread 411c and a female screw thread 541, and the inner stopper 40 and the cap 50 while a state in which they are assembled is maintained are capped to a bottle 60, and when the cap 50 is removed initially, the cap 50 is firstly rotated in a direction of closing to have a junction section 52 broken, and then the cap 50 is rotated in a direction of opening so that the lid body 42 of the inner stopper 40 is removed together with cap 50, thereby causing the inner stopper 40 also to be in a state of being opened.

Abstract: The invention relates to a cap assembly which is put over a mouth of a bottle, and an assembly method thereof, and provides a cap assembly which prevents an occurrence of misunderstanding when opening a cap initially and has good usability, and a method for assembling thereof. There are included an inner stopper and a cap, and the inner stopper and the cap are assembled in a state in which a lid section is received in a receiving section and a protrusion section is positioned below the lid section, and the lid section is arranged at a position which is inside the receiving section and has a space between an inner surface of a shell section and the lid section, so that an occurrence of misunderstanding by torque changing before the inner stopper is opened is prevented.

Abstract: A plug in which the base end portions of an image guide comprise an image guide fiber and an image guide rod. A light guide comprising a light guide fiber and a light guide rod are fixed to a plug main body in a parallel state. The plug and a socket can be connected. The diameter of a position-aligning hole portion into which the base end of the image guide rod is inserted is set to be substantially the same as the outer diameter of the image guide rod, while the diameter of a position-aligning hole portion into which the base end of the light guide rod is inserted is set to be greater than the outer diameter of the light guide rod.

Abstract: An endoscope cover fixing device able to reliably fix the position of a cover to an endoscope without associated damage. The endoscope cover fixing device includes a fixing device main body and a wedge-shaped portion. Insert portions 43a, 44a into which the endoscope 31 is insertable are formed in the fixing device main body 42. The wedge-shaped portion 46 is provided in the insert holes 43a, 44a of the fixing device main body 42 to protrude to the distal end side of the fixing device main body 42. The wedge-shaped portion 46 is inlayed through a proximal end 23 side of the cover 21 into a gap between the endoscope 31 and the cover 21.

Abstract: An endoscope cover fixing device to reliably fix a cover to an endoscope without associated damage. The endoscope cover fixing device includes a fixing device main body and a pair of fixing protrusion portions. The fixing device main body includes a curved portion and insert holes, and is deformable in the direction in which the bend amount increases. The pair of fixing protrusion portions, which have contact surfaces, are provided to protrude from a concave surface side of the fixing device main body and are disposed in two opposing regions of the concave surface. The contact surfaces are disposed in parallel with a fixed distance therebetween. During deformation of the fixing device main body, the pair of fixing protrusion portions move in parallel in opposing directions. As a result, the contact surfaces contact opposing positions on the outer circumferential surface of the endoscope by way of the cover.

A light guide comprising a light guide fiber and a light guide rod are fixed to a plug main body in a parallel state. The plug and a socket can be connected. The diameter of a position-aligning hole portion into which the base end of the image guide rod is inserted is set to be substantially the same as the outer diameter of the image guide rod , while the diameter of a position-aligning hole portion into which the base end of the light guide rod is inserted is set to be greater than the outer diameter of the light guide rod.

Abstract: The tip end of a tubular body is oriented towards an inner bottom face of a recess for holding a heating body, then the outer peripheral surface is oriented towards the inner peripheral surface of a heating body, and said tubular body is inserted into the heating body from the open side of the recess in the axial direction. This allows a film to be shaped from the tip end around the outer peripheral surface of the tubular body. The film and the heating body are heated in an overlapping state, and the film is welded to the outer peripheral surface of the tubular body.
