Abstract

The invention provides a dispenser that allows users to determine the operating mode based on the appearance of the head portion, specifically whether or not it can be pressed down. [Solution] The device comprises a fixing member 2 fixed to the neck 102 of the container body 100, an operating member 30 that discharges the contents from the discharge port 49 of the head portion 40 by raising and lowering relative to the fixing member 2, and a spring member 50 that biases the operating member 30 upward. Between the fixing member 2 and the operating member 30, a switching mechanism G is formed that switches between a mode that restricts the downward pressing of the head portion 40 and a mode that allows the downward pressing of the head portion 40 by rotating the head portion 40. The top portion 58 of the spring member 50 is in contact with the lower surface of the top wall 41 of the head portion 40, and a window portion 42 is opened in a part of the circumferential direction of the top wall 41, so that a display means A that indicates whether or not the head portion 40 can be pressed down is exposed to the outside through this window portion 42, which is formed by a part of the top portion 58.

Claims

1. A fixing member (2) is fixed to the mouth and neck (102) of the container body (100), An operating member (30) moves up and down relative to the fixing member (2) to discharge the contents inside the container (100) from the discharge port (49) of the head portion (40) positioned above the fixing member (2), The device comprises a spring member (50) interposed between the fixing member (2) and the operating member (30) and biasing the operating member (30) upward, Between the fixing member (2) and the operating member (30), a switching mechanism (G) is formed that rotates the head portion (40) around the central axis (O) between a locked position (L) and an unlocked position (U), thereby switching between a mode that restricts the downward movement of the head portion (40) and a mode that allows downward movement. Discharger characterized in that the top portion (58) of the spring member (50) is brought into contact with the lower surface of the top wall (41) of the head portion (40), and a window portion (42) is opened in a part of the circumferential direction of the top wall (41), so that an indicator means (A) formed from a part of the top portion (58) that indicates whether or not the head portion (40) can be pressed down is exposed to the outside through this window portion (42).

2. The discharger according to claim 1, characterized in that at least the display means (A) has a different color from the head portion (40) when viewed from above.

3. By forming a rotation-preventing means (D) between the fixing member (2) and the leg portion (52) of the spring member (50), the head portion (40) is configured to rotate relative to the spring member (50) when the head portion (40) is rotated. The discharger according to claim 1 or claim 2, characterized in that the window portion (42) moves relative to the display means (A) in the rotational direction of the head portion (40), thereby causing the display means (A) to move in and out of the window portion (42) relative to the window portion (42) when viewed from above.

4. By forming a rotation-preventing means (D) between the fixing member (2) and the leg portion (52) of the spring member (50), the head portion (40) is configured to rotate relative to the spring member (50) when the head portion (40) is rotated. The discharger according to claim 1 or claim 2, characterized in that the window portion (42) moves relative to the display means (A) in the rotational direction of the head portion (40), and as this rotation occurs, a reciprocating means (B) is provided to move the display means (A) forward and backward into the window portion (42) from below, and the reciprocating of the display means (A) indicates whether or not the head portion (40) can be pressed down.

5. The spring member (50) is formed to rotate together with the operating member (30) when the head portion (40) is rotated. The discharger according to claim 1 or claim 2, characterized in that the display means (A) is fitted into the window portion (42) from below, and the displacement of the rotational position of the display means (A) relative to the fixing member (2) allows for the identification of the on / off switching of the downward pressing operation of the head portion (40).
