Abstract: Mounts are provided on the inside surface of the left and the right sides of a seat cover on the underside of a chair, and positioning pins with heads and fastening members are provided on the upper surfaces of the bases of armrests. Each mount includes keyholed-shaped positioning holes respectively having holes for insertion of the heads of the positioning pins and slits of a width suitable for slidably receiving the rods of the positioning pins. Each mount also includes a support hole for the fastening member to be engaged in. When the positioning pins are located at the rear ends of the slits of the positioning holes, the armrest is fixed to the mount through the support hole by the fastening member. Thus the armrests are removably assembled with the chair body. The seat cover has upper and lower protrusions which contact the mount and the base of the armrest, respectively. The mount is bent so that its outboard and inboard portions are inclined relative to each other.

The liquid-pumping container has a structure which simplifies the replacement procedure of the bag containing the liquid substance and reduces the cost of manufacturing.

Abstract: A holder for containing an inner flexible container comprising side walls 15, a bottom wall 16 and a top wall 17 is disclosed. The side walls 15 comprises; a first side wall having a handle 18 projecting in an outer direction, a second side wall having an open window 19 provided in a lower position thereof, a third side wall which is opposite to the second side wall and the upper portion of which has an opening 20 opened to the top end thereof. The top wall 17 has a guide notch which is opened in the opening 20 above the third side wall. The flexible inner container is inserted into the holder in an inclined state through the upper opening 20 of the third side and then is stood in an erect posture, interfitting the mouth of the flexible container into the guide notch of the top wall 17. The contents is dispensed through the mouth by using a torque lowering the side wall which is positioned opposite to the ear 18.

Abstract: A chair with freely attachable and removable armrests comprises a basic chair unit wherein a leg and a back rest portion attached to a frame on a lower surface of a seat portion, the two ends of the lower surface in the lateral direction of the seat portion being provided with armrest attachment portions. An attachment end portion provided at the lower end of each armrest comprises a positioning protrusion portion that can be inserted into a positioning hole provided in an internal portion of one of the armrest attachment portions. An attachment base portion (spacer) is positioned and held in close contact with guide surfaces along a guide portion of the armrest attachment portion, and a removal-prevention element in the armrest attachment portion is provided for preventing the removal of the attachment end portion. Thus, armrests can be removed from the basic chair unit by a simple operation.
