Inventor: IKEMURA TAKESHI
IPC: A23G9/20
Filed: 1999-11-29
Abstract: PROBLEM TO BE SOLVED: To provide a distribution container for a plastic food such as soft ice cream, and to provide a device for extracting a content. SOLUTION: This distribution container comprises a container main body in which the extrusion port of the bottom portion can be closed with a peelable adhesive tape and a lid for closing the upper edge opening. The lid comprises a flat surface portion and a standing peripheral portion. The standing peripheral portion is brought into contact with the inner wall surface of the peripheral wall portion of the container main body along the gradient of the peripheral wall portion and simultaneously extended, when the lid is pressed down to extrude the content of the container main body from the extrusion port, and has wave-like or circular circumferential grooves having a shape following the inner wall surface in the bottom portion of the container main body.  When the upward or downward press mechanism of an extruder in an extraction device presses down the lid of the distribution container, the lid is expanded in the centrifugal direction with the pressing pressure to press the standing peripheral portion of the lid to the peripheral inner wall surface of the container main body, and is simultaneously downward moved. In the bottom portion of the container main body, the flat surface portion of the lid is followed to the bottom portion by a restoring force, and when the lid is upward moved, a plastic food in the container main body is extruded from the adhesive tape-peeled extrusion port with an elastic pad restoring its original shape.

Abstract: PURPOSE: To decrease an origin positioning error by starting moving at an assigned speed in an assigned direction after starting origin resetting action, and setting a point where a sinusoidal wave current first shows a zero electrical angle as the origin after passing through a proximity sensor. CONSTITUTION: After starting origin resetting action, a pulse motor 2 rotates to make a reflector 4 pass through a position of an optical proximity sensor 3, so that a proximity sensor signal changes (point b) and makes the pulse motor 2 start deceleration to stop it (point c). Between the points (b) and (c), the pulse motor 2 passes through the origin, that is, a point (d) where a drive sinusoidal wave current first shows a zero electrical angle after passing through the optical proximity sensor 3, moves in an opposite direction to starting time of origin resetting by a number of delivery pulses during the time till the stopping point (c), and is positioned in and origin position (point e). In this way, excitation torque at origin stop time can be held stable, to enable an origin positioning error to decrease.
