The present invention is a cap with a fixed-quantity discharge function that is attached to a container mouth and can take out a fixed amount of contents, and in order to solve the above problems, a discharge port is formed and fixed to the container mouth. To partition the stopper, the cylinder portion rotatably held by the inner stopper, and the measuring chamber formed on the upper portion of the cylinder portion and corresponding to the discharge port at the rotational end position in the closing direction with respect to the inner stopper. A measuring member having a wall, a peripheral wall screwed to the outer surface of the tubular portion of the measuring member, an overcap having a top wall that closes the upper end of the peripheral wall and covers the measuring chamber, and the cylinder of the measuring member. The overcap is arranged between the portion and the peripheral wall of the overcap so as to be movable along the axis of the cap along with the upside-down operation of the container and to be rotatable in synchronization with the overcap. The overcap is positioned on the lower end side of the peripheral wall so as to be non-rotatably locked to the measuring member, while being closer to the upper end side of the peripheral wall than the position of the container in the upright position under the tilted posture of the container. Positionally, it comprises a regulator that allows the overcap to rotate in the opening direction with respect to the weighing member.

In the cap with a fixed quantity discharge function of the present invention, the restricting body has ribs protruding toward the tubular portion of the measuring member, and the outer surface of the tubular portion of the measuring member has the said. When the regulator is located on the lower end side of the peripheral wall in the upright posture of the container, it is adjacent to both sides of the rib of the regulator, and a pair of rotation regulators that regulate the rotation of the regulator with respect to the measuring member. It is preferable that ribs are formed.

Further, in the cap with a fixed quantity discharge function of the present invention, the regulation is applied to the outer surface of the tubular portion of the measuring member when the overcap is rotated in the opening direction under the tilted posture of the container. It is preferable that an engaging rib is formed so that the rib of the body can be overcome and engaged.

Further, in the cap with a fixed quantity discharge function of the present invention, the rib of the restricting body engages with a male screw formed on the outer surface of the tubular portion after getting over the engaging rib of the measuring member. It is preferable that it is possible.

Further, in the cap with a fixed quantity discharge function of the present invention, an inward convex portion protruding toward the inner plug is formed on the inner surface of the tubular portion of the measuring member, and the inner plug has the said By abutting the inwardly convex portion in the rotation direction of the measuring member, the rotation of the measuring member with respect to the inner plug is caused to the rotation end position in the closing direction of the overcap and the rotation ending in the opening direction of the overcap. It is preferable that an outward convex portion is formed between the position and the measuring chamber at the rotation end position in the closing direction so as to coincide with the discharge port of the inner plug.

In the upright position of the container, the regulator is located on the lower end side of the peripheral wall of the overcap and locks the overcap to the measuring member so as not to rotate relative to the measuring member, so that the overcap is prevented from being opened. On the other hand, when the container is tilted, the contents in the container are taken into the measuring chamber from the discharge port and weighed, and the regulator moves to the upper end side of the peripheral wall from the position when the container is in the upright posture by its own weight. Then, since the overcap is allowed to rotate with respect to the weighing member in the opening direction, the overcap can be removed and the weighed contents can be taken out.

As shown in FIG. 1, the cap 10 has an inner plug 14 having a discharge port 12 formed and fixed to the mouth portion E1 of the container E, a tubular portion 16 rotatably held by the inner plug 14, and the cylinder. A weighing member 22 having an upper wall 20 formed on the upper portion of the portion 16 and partitioning a measuring chamber 18 corresponding to the discharge port 12 at a predetermined rotation position with respect to the inner plug 14 and a screw on the outer surface of the tubular portion 16 of the measuring member 22. A container between the worn peripheral wall 24 and the overcap 28 having a top wall 26 that closes the upper end of the peripheral wall 24 and covers the measuring chamber 18 and the tubular portion 16 of the measuring member 22 and the peripheral wall 24 of the overcap 28. It is arranged so that it can move along the cap axis X and rotate synchronously with the overcap 28 along with the upright operation of E, and is located on the lower end side of the peripheral wall 24 of the overcap 28 under the upright posture of the container E. While the cap 28 is locked to the measuring member 22 so as to be relatively non-rotatable, the cap 28 is located on the upper end side of the peripheral wall 24 with respect to the position of the container E in the upright posture under the tilted posture of the container E, and is an overcap with respect to the measuring member 22. It includes a regulator 30 that allows the 28 to rotate in the opening direction. The inner plug 14, the measuring member 22, the overcap 28, and the restricting body 30 constituting the cap 10 are each made of synthetic resin, and can be formed by injection molding or the like. Hereinafter, a more specific description will be given.

As shown in FIGS. 1 to 4, the inner plug 14 discharges, for example, granular contents contained in the container E toward the measuring member 22, and forms an annular groove between them to form an annular groove. A concentric outer cylinder 32 and inner cylinder 34 into which the mouth portion E1 of the container E is inserted and fixed, and a lead-out wall 36 extending upward while reducing the diameter in a funnel shape from the lower end of the inner cylinder 34. Have. At the upper end of the lead-out wall 36, the discharge port 12 is formed at a position eccentric with respect to the cap axis X. In the illustrated example, the inner plug 14 is fixed by fitting the outer cylinder 32 to the mouth portion E1 of the container E, but the fixing method is not particularly limited, and the mouth portion E1 of the container E is placed in the annular groove. It may be fixed by press-fitting.

As shown in FIG. 1, the measuring member 22 measures the contents discharged from the discharge port 12 through the lead-out wall 36 of the inner plug 14, and is rotatably held by the inner plug 14. The measuring member 22 moves upward by engaging the inwardly convex portion 38 formed on the inner surface of the tubular portion 16 with the circumferential groove 40 formed on the outer surface of the outer cylinder 32 of the inner plug 14 in the upward direction. It is held inseparable. In addition, "non-removable" means that it cannot be separated from the inner plug 14 in normal use, and does not mean that it cannot be separated by any physical method. In the illustrated example, the two inwardly projecting portions 38 are formed at positions facing each other with the cap axis X interposed therebetween.

As shown in FIG. 2, in relation to the inwardly projecting portion 38 of the measuring member 22, the inner plug 14 is brought into contact with the inwardly projecting portion 38 in the rotational direction of the measuring member 22 to measure the inner plug 14 with respect to the inner plug 14. The rotation of the member 22 is restricted between the rotation end position of the overcap 28 in the closing direction (arrow C1 direction in FIG. 2) and the rotation end position of the overcap 28 in the opening direction (arrow C2 direction in FIG. 6). The outward convex portion 42 is formed. That is, the rotation end position in the closing direction is the position where the inward convex portion 38 abuts on the outward convex portion 42 in FIG. 2, and the rotation end position in the opening direction is the position where the inward convex portion 38 abuts in FIG. Is the position where is in contact with the outward convex portion 42. The inwardly projecting portion 38 and the outwardly projecting portion 42 are arranged so that the measuring chamber 18 coincides with the discharge port 12 of the inner plug 14 at the rotation end position in the closing direction (see FIGS. 1 and 4).

As shown in FIG. 1, the overcap 28 covers the measuring member 22 and closes the outlet side of the measuring chamber 18, and is formed on the peripheral wall 24 of the overcap 28, so that the screw 44 is attached to the measuring member 22. It is configured to be removable by engaging with a male screw 46 formed on the tubular portion 16. Further, the thickness of the peripheral wall 24 is reduced from the inner surface side below the female screw 44, and the restricting body 30 is arranged in the thin-walled region thereof. At the lower end of the peripheral wall 24, a protruding portion 48 is formed which projects inward in the radial direction to prevent the restricting body 30 from falling off.

The regulator 30 can move by its own weight along the cap axis X within the thin region of the peripheral wall 24 of the overcap 28 due to the upside-down operation of the container E, and when the cap 10 is in the upright posture, it is weighed. The opening by the relative rotation of the overcap 28 with respect to the member 22 is regulated, and the opening by the relative rotation of the overcap 28 with respect to the measuring member 22 is permitted only when the cap 10 is in the tilted (inverted) posture. As shown in FIGS. 1 and 5, the restricting body 30 is formed from an annular band portion 50 having a diameter larger than that of the tubular portion 16 of the measuring member 22 and a position at the upper end of the band portion 50 facing the cap axis X. It has two projecting pieces 52 protruding upward. The number of projectiles 52 may be one. Both sides of the projecting piece 52 can be locked with the peripheral wall 24 of the overcap 28 in the rotational direction (see FIGS. 3 and 7), whereby the restrictor 30 rotates (co-rotates) with the overcap 28 in synchronization. .. Each projecting piece 52 is formed with a rib 54 projecting toward the tubular portion 16 of the measuring member 22. The rib 54 is inclined at an angle equal to the lead angle of the female screw 44 of the overcap 28 with respect to the plane orthogonal to the cap axis X.

In relation to the rib 54 of the restricting body 30, on the outer surface of the tubular portion 16 of the measuring member 22, as shown in FIGS. 3 and 5, the restricting body 30 is placed on the lower end side of the peripheral wall 24 under the upright posture of the container E. A pair of rotation restricting ribs 56 and 58 are formed adjacent to both sides of the rib 54 of the restricting body 30 when located at, and restricting the rotation of the restricting body 30 with respect to the measuring member 22 and the rotation of the overcap 28. There is. The rotation restricting ribs 56 and 58 are formed in the vicinity of the lower end portion of the male screw 46 formed on the outer surface of the tubular portion 16. One 56 of the pair of rotation restricting ribs is formed continuously from the lower end of the male screw 46 downward on the cap axis X, and the other rotation restricting rib 58 is restricted between the pair of rotation restricting ribs 56 and 58. The ribs 54 of the body 30 are formed along the cap axis X at positions that form a gap that allows them to float. Therefore, the pair of rotation restricting ribs 56 and 58 also play a role of guiding the movement of the restricting body 30 accompanying the forward inverted operation of the container E along the cap axis X.

Further, as shown in FIG. 7, on the outer surface of the tubular portion 16 of the measuring member 22, when the overcap 28 is rotated in the opening direction under the tilted posture of the container E, the rib 54 of the regulating body 30 is provided. Engagement ribs 60 that engage so as to be overcome are formed. The engaging rib 60 is also visible in FIG. The engaging rib 60 engages with the rib 54 of the regulating body 30 under the tilted posture of the container E, and when the overcap 28 is rotated in the opening direction, only a predetermined rotation range, in this example, the closing direction The overcap 28 and the measuring member 22 are rotated together with the inner plug 14 of the measuring chamber 18 only in the rotation range from the rotation ending position (see FIG. 2) to the rotation ending position (see FIG. 6) in the opening direction. After shifting the measuring chamber 18 from the discharging port 12 of the inner plug 14 by shifting it from the discharging port 12 of the regulating body 30, the rib 54 of the regulating body 30 is overcome to allow the overcap 28 to be opened. be. In this example, the engaging rib 60 is formed lower than the rotation restricting ribs 56 and 58 so that the rib 54 of the restricting body 30 surely gets over the engaging rib 60. Further, the engaging rib 60 may have a trapezoidal cross-sectional shape in which both side surfaces are inclined, a shape in which an inclined surface is provided on one side, or the like, and the overcap 28 and the measuring member 22 may be provided with a predetermined rotation range. The shape and dimensions of the restricting body 30 are not particularly limited as long as they can be rotated together and then overcome by the rib 54 of the restricting body 30.

In order to take out a certain amount of the contents in the container E by using the cap 10 having the above configuration, first, as shown in FIG. 8, the discharge port 12 of the inner plug 14 and the measuring chamber 18 of the measuring member 22 coincide with each other. In this state, the container E is tilted from an upright position. As a result, the contents in the container E (one granular material in the illustrated example) enter the measuring chamber 18 and are weighed. When the cap 10 is opened in the upright posture of the container E as shown in FIGS. 1 and 5, the force for rotating the over cap 28 is applied to the rib 54 of the restricting body 30 and the measuring member 22. It is transmitted to the measuring member 22 through the contact with the pair of rotation restricting ribs 56 and 58, but at the rotation end position in the opening direction, the measuring member 22 abuts the inward convex portion 38 and the outward convex portion 42. Because the rotation is restricted by, it is not possible to rotate in the opening direction beyond the rotation end position. Therefore, it is possible to prevent the opening by a young child.

In order to open the cap 10, it is necessary to tilt the container E. In this state, the restricting body 30 moves toward the upper end side (downward in the drawing) of the peripheral wall 24 due to its own weight as shown in FIGS. 8 and 9. Moving. When the restricting body 30 moves to the upper end side of the peripheral wall 24, it becomes in a state where it can engage with the engaging rib 60 serially provided at the end of the screw 46 of the measuring member 22, and from this state, the overcap 28 is opened in the opening direction. When rotated, the overcap 28 and the weighing member 22 rotate together to the rotation end position in the opening direction shown in FIGS. 6 and 7 due to the linkage between the rib 54 and the engaging rib 60. As a result, as shown in FIGS. 10 and 11, the positions of the measuring chamber 18 and the discharging port 12 are displaced, and the discharging port 12 is blocked by the upper wall 20 of the measuring member 22. Then, when the overcap 28 is continuously rotated in the opening direction, the measuring member 22 cannot rotate further in the opening direction due to the contact between the outward convex portion 42 and the inward convex portion 38 (see FIG. 6). As shown in the above, the rib 54 of the regulating body 30 gets over the engaging rib 60 of the measuring member 22, and after getting over the engaging rib 60, the screw of the measuring member 22 is screwed in the same manner as the female screw 44 of the overcap 28. When engaged with 46, finally, as shown in FIG. 13, both the overcap 28 and the restricting body 30 are separated from the measuring member 22 so that the weighed contents can be taken out.

When the overcap 28 is reattached after the contents are taken out, the restrictor 30 moves to the upper end side of the peripheral wall 24 when the overcap 28 is placed on the measuring member 22, so that the container E is made upright. Can be done in the state.

Therefore, according to the cap 10 of the present embodiment, it is possible to provide a fixed-quantity discharge function and prevent opening by a young child.

Further, in the cap 10 of the present embodiment, an inward convex portion 38 projecting toward the inner plug 14 is formed on the inner surface of the tubular portion 16 of the measuring member 22, and the inner plug 14 has an inward convex portion 38. The rotation of the measuring member 22 with respect to the inner plug 14 is caused between the rotation ending position of the overcap 28 in the closing direction and the rotation ending position of the overcap 28 in the opening direction. Since the outward convex portion 42 is formed and the measuring chamber 18 coincides with the discharge port 12 of the inner plug 14 at the rotation end position in the closing direction, the overcap 28 is rotated to the final position in the closing direction. The measuring chamber 18 can be surely matched with the discharge port 12 only by making the measuring chamber 18 match.

Further, in the cap 10 of the present embodiment, on the outer surface of the tubular portion 16 of the measuring member 22, when the overcap 28 is rotated in the opening direction under the tilted posture of the container E, the rib 54 of the regulating body 30 is formed. Since the engaging rib 60 is formed so as to be able to get over the rib 54, the rib 54 and the engaging rib 60 are formed until the overcap 28 and the measuring member 22 reach the rotational end position in the opening direction shown in FIG. By engaging with, the overcap 28 and the measuring member 22 can be allowed to rotate with respect to the inner plug 14, and the discharge port 12 can be blocked by the upper wall 20 of the measuring member 22. After reaching, the rib 54 exceeds the engaging rib 60, and the overcap 28 can be rotated with respect to the measuring member 22 in the opening direction, so that the overcap 28 can be removed.

Further, in the cap 10 of the present embodiment, the rib 54 of the regulating body 30 engages with the male screw 46 formed on the outer surface of the tubular portion 16 of the measuring member 22 after getting over the engaging rib 60 of the measuring member 22. Since it is possible, the regulator 30 can be removed together with the overcap 28.

According to the present invention, it is possible to provide a cap with a fixed-quantity discharge function that can provide a child resistance function in addition to the fixed-quantity discharge function and prevent opening by a young child.
