ている。<Prior Art> Conventionally, a paste-like material has been generally used, which is stored in a tube made of a flexible material and squeezed out by pressing the tube. Recently, instead of this, in order to push out a certain amount of the contents with one-touch operation, a cylindrical casing with a discharge hole at the top, a piston that fits tightly into the inner wall of the casing and can slide in the axial direction, and the piston. It consists of a rod-shaped rack member that penetrates the top wall of the casing and is movable up and down, and a clamp member that is attached to the piston and engages with the rack when the rack member ascends and releases the engagement when the rack member descends. A container for dispensing a paste-like material is known, for example, from Japanese Patent Application Laid-open No. 142854/1983, which is equipped with actuating means for raising and lowering a member. However, all of these known containers still have the inconvenience of having to remove the lid manually each time they are used, and that the contents cannot be discharged with a single action.

するなどの不都合を生ずる可使性が確認された。In order to eliminate this inconvenience, the present inventor proposed a container in which a rod-shaped rack member is simultaneously raised and lowered in conjunction with the opening and closing operations of the lid covering the discharge hole in the upper part of the container. Proposed. While this proposal has great significance in that it realizes a complete one-touch operation system, it also causes problems such as paste-like substances remaining on the edge of the discharge hole sticking to the lid body.
The edge of the discharge hole may hang down, staining the container wall and creating an unsanitary feeling, solid matter that dries and solidifies at the discharge port may interfere with dispensing during the next use, or it may become mixed into the discharged paste as lumps, causing other inconveniences. Usability was confirmed.

明した。In order to prevent such residual adhesion of excess paste near the edge of the discharge hole, the container proposed in JP-A-57-114487 has a connecting part that is loosely fitted into the middle part of the rod-shaped rack member. Immediately after the extrusion operation of the contents is completed, the free stroke generated in the loose fitting connection creates a negative pressure in the container, causing an appropriate amount of paste-like material in the discharge hole to move backward, and then the rod-shaped rack member is pulled up. The device is designed to allow the piston to move upward in preparation for the next extrusion operation. However, the paste-like suction effect of this container is caused by the so-called "play" of the loose-fitting connection part embedded in the paste-like material in the container, so it is particularly difficult to use when the paste-like material has a high viscosity. It has been found that there are many cases in which paste-like substances that have entered the loose fitting portion interfere with the movement within the self-seam stroke, preventing complete operation.

い前記円弧状片持ばね２４が大きい負荷を受けて弯曲し
、反対に負荷に抗して弾性回復伸張する撓み変形を押圧
力加除手段となすことである。In the most preferred embodiment, as shown in the figure, the arcuate cantilever spring 24 bends under a large load due to the action of the elevating means, and conversely, the bending deformation in which it elastically recovers and expands against the load is used as the pressing force release means. It is what you do.

設計工夫を加えることは好ましいことである。Furthermore, instead of directly pressing the diaphragm with the side surface of the arc-shaped cantilever spring, such as a bar spring or leaf spring 24, the pressing force applying/releasing means presses the spring 24 against the diaphragm 18 as shown in FIGS. 9 and 11. Convexity 27 at the contact point
It is preferable to provide a design device such that the protrusion 27 presses the bulging surface upwardly.
