摘要： PURPOSE:To reduce waste of an ointment by linking a cartridge changeable to the boy of a push type extrusion structure with a ratchet to allow the supplying of a fixed amount of the ointment accurately little by little. CONSTITUTION:An outer cylinder 4 of the main body having a moving body 5, an inner cylinder 6 and the outer cylinder 4 is provided with a semi-fluid matter housing cartridge 2 adapted to house a semi-fluid matter like an ointment inside while having a slide member 3 free to load or unload. A cap 1 is removed and when a press operation part 66 of the inner cylinder 6 is pressed forward against the energization of a coil spring 7, a retaining part 6a of the inner cylinder 6 is retained with a protrusion 5a of the moving object 5 to make the moving body 5 move forward to the outer cylinder 4 so that the slide member 3 slides forward at a fixed distance to extrude the ointment by a fixed amount at an extrusion port 2a. In the advancing of the moving body 5, a protrusion 5d at one rear position of the protrusion 5c passes under a retaining piece 4a of the outer cylinder 4 to be retained with the retaining piece 4a. Then, the inner cylinder 6 moves backward by an energizing force of the coil spring 7 and returns to the original position.

摘要： PROBLEM TO BE SOLVED: To provide a many space type syringe which is at a low cost and has good productivity. SOLUTION: The syringe 10 includes an approximately cylindrical outer cylinder 12, a pressing member 14 which sticks to the internal face 12a of the outer cylinder 12 and in which the internal face 12a is slidably arranged, and a plug body 16. A protruding portion 34 is formed in the principal plane 16a of the plug body 16 so that a top 34a may take eccentricity to the principal plane 16a. Pressure from the side of an opening end 18 applied to the plug body 16 in connection with sliding to the arrow A direction of the pressing member 14 acts in an arrow B direction and deforms the plug body 16 in a condition of touching a blocking end 20 so that it may be crooked. Thus, a first gap 38 and a second gap 40 are formed between the internal face 12a of the outer cylinder 12 and the plug body 16. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an injector of a simple structure which can effectively prevent 'post dripping-off' after extrusion of the material housed therein and a plunger and sealing body for this injector. SOLUTION: This injector has the sealing body disposed at the tip of a plunger body. This sealing body has a base portion which extends from the plunger body to the tip side of a barrel, and a flange portion which extends outward in the radial direction from the base portion and of which the outer peripheral edge delineates a housing space in the barrel by abutting on the inner peripheral surface of the barrel. This flange portion is formed to be elastically deformed by the reaction force from the housing material when sliding the sealing body toward the tip side of the barrel by exerting pressing force to the plunger body in order to extrude the housing material and to push back the plunger body toward the base end side of the barrel by utilizing its own restitutive force when the pressing force is relived.

摘要： PURPOSE: To provide a container which enables the direct injection of powder medicines into the celom by detaining the top edge of the cap part of a powder medicine capsule inserted in an inverted state into an insertion hole to a detaining pawl of a supporting cylindrical member and-detaching this cap part from a body part at the time of rising of an approximate ly L-shaped crown member and unsealing the capsule. CONSTITUTION: The top edge of the cap part Pc of the powder medicine capsule inserted in the inverted state into the insertion hole 1h is detained to the detaining pawl R installed in the supporting cylinderical member 2 and is detached from the body part Pb at the time of r rising of the approximately L-shaped crown member 1, by which the capsule is unsealed. The lower edge of the body part Pb surely drops the top end of the cap part Pc into the space X in the approximately L-shaped crown member 1 at the time of descending of the approximately L-shaped crown member 1. A valve mechanism 4 of the injection container is closed when a flow passage 43 of the pneumatic feeding container body in a connecting member 41 opens into a position near the rear surface of a upper cap member 42 and is held erecting. This valve mechanism sucks the outdoor air through a through-hole 40h disposed in the horizontal part 40b of the lower cap member 40. On the other hand, the valve mechanism 4 moves and the flow passage 43 is opened, by which the gas for pneumatic feeding is released from the container V into the space X at the time of inversion.
