摘要： Provided is a cartridge-type dispenser suitable for extruding viscous materials, wherein the piston does not fall easily out of the cartridge body and yet is capable of extruding the contents with a smooth action. The cartridge-type dispenser is provided with a main body (1) that has a filling space (M) for the contents and is equipped with an extrusion nozzle (1a) on the front end thereof, and a piston (2) that is slidably disposed in the filling space (M) of said main body (1) and extrudes the contents of said filling space (M) from the tip of the extrusion nozzle (1a) by application of a pressing force. The piston (2) is configured from a body (2a) that has an outer circumferential wall that runs along the inner wall of the main body (1) and is disposed inside the inner wall of said main body with a gap therebetween, a front wall (2b) that is provided on one end of said body (2a) and directly contacts the contents of the filling space (M), and a rear wall (2c) that is provided on the other end of said body (2a) whereon the rod of a pressing tool is pressed to apply a pressing force on the piston (2) itself. On the outer circumferential wall of said body (2a), protrusions (3) are provided, which touch the inner wall of said main body (1). Said points of contact form the sliding parts of the piston (2) but do not seal the interior of said main body.

摘要： Provided is a member for discharging a liquid which is capable of effectively preventing the liquid from spurting when a container is opened. An inner plug 1 is provided with: a nozzle part 2; a base part 3 for engaging with a mouth portion of the container; and a hollow cylindrical skirt portion 4. The nozzle part 2 has a nozzle upper portion 5 extending from an upper face 16 of the base part 3 and a nozzle lower portion 6 extending from a lower face 17 of the base part 3. The nozzle upper portion 5 has a discharge opening 7, and the nozzle lower portion 6 has an inflow opening 8, forming an inner passage 9 running from the inflow opening 8 to the discharge opening 7. The nozzle lower portion 6 is disposed inside of the skirt portion 4 in the radial direction and has a tip part 11 with an oblique face 12, and the inflow opening 8 is formed in the oblique face 12. The nozzle lower portion 6 has a columnar part 10 extending perpendicularly from the lower face 17 of the base part 3. The columnar part 10 has a side face 24 and a bottom face 25, wherein an edge section between the side face 24 and the bottom face 25 forms a corner part 13 having a 90° angle.
