A rod that extends toward the head, a dispensing nozzle that can move forward and backward with respect to the head of the rod, has a path that is closed by its forward movement and opened by its backward movement, and is connected to the rear end of this dispensing nozzle. It consists of a partition wall that surrounds the rod and forms a measuring space for the contents in the compartment recess,
In the bottom of the compartment recess, a passage for allowing the contents in the container to pass through is provided,
The partition wall is provided with a seal member slidable along the side wall of the compartment recess, and a valve body that opens and closes the passage when the dispensing nozzle is opened and closed .
A quantitative dispenser comprising an opening for exposing the head of the rod and the dispensing nozzle, and a cover for clamping and fixing the dispenser main body to the mouth of the container at the side wall edge. is there.

  The quantitative dispenser configured as described above can be provided with an overcap that covers and hides the head of the rod and the dispensing nozzle together with the cover, and is engaged and held outside the mouth of the container. In this case, it is desirable that the overcap is provided with an engaging convex portion that engages with the tip of the pouring nozzle on the inner wall thereof.

  The fixed quantity dispenser is composed of at least three members: a dispenser body that is suspended at the mouth of the container, a dispensing nozzle that is integrated with the partition wall, and a cover that fixes the dispenser body to the mouth of the container. Therefore, the structure is simplified and efficient integration can be performed.

Hereinafter, the present invention will be described more specifically with reference to the drawings.
FIG. 1 shows an embodiment of a metering dispenser according to the present invention.

  In the figure, 1 is a container for storing the contents, 2 is a pouring device body that is suspended at the mouth 1a of the container 1 and forms a compartment recess c therein, and 3 is a compartment recess c of the dispenser body 2. It is a rod that stands from the bottom and extends toward the open end of the compartment recess c. This rod 3 is formed integrally with the dispenser body 2 and has a recess (or groove) 3b at the lower end of the head 3a (see FIG. 3).

  4 is a pouring nozzle that can move forward and backward with respect to the head 3 a of the rod 3. As shown in the enlarged view of the main portion of FIG. 2, the discharge nozzle 4 forms a gap with the concave portion (or groove portion) 3 b of the rod 3 by its backward movement (in the x direction), and below the discharge nozzle 4. While the inner convex portion 4a formed on the rod is opened, the inner convex portion 4a of the dispensing nozzle 4 is brought into contact with the head portion 3a of the rod 3 by its forward movement (x ′ direction), and the dispensing nozzle 4 is closed. Has a path k. In addition to the inner convex portion 4a, the dispensing nozzle 4 has an engaging portion 4b that protrudes outward on the upper side surface.

  Reference numeral 5 denotes a partition wall which integrally connects to the rear end of the pouring nozzle 4 and surrounds the rod 3 and forms a content measuring space m in the partition recess c. The partition wall 5 has a top plate 5a extending outward from the rear end of the pouring nozzle 4 and a side wall 5b hanging from the outer end of the top plate 5a. The side wall 5b has a partition recess c. Of the seal member 5c slidable along the side wall (inner side wall of the extractor body 2) and the contact and separation at the lower end of the side wall 5b of the partition wall 5 and function as an on-off valve in relation to the dispenser body 2 It has a body 5d.

  Reference numeral 6 denotes a passage which is provided at the bottom of the partition recess c and allows the contents in the container 1 to pass therethrough. At least one passage 6 is formed at the connecting portion between the bottom wall and the side wall of the dispenser body 2, and the dispensing nozzle 4 moves forward together with the partition wall 5 and opens when the valve body 5d separates, The dispensing nozzle 4 moves backward together with the partition wall 5 so that the valve body 5d comes into contact with and conforms to the closing. This passage 6 is formed with an annular rising wall w with which the lower end of the side wall 5b of the partition wall 5 and the inner side wall abut against the bottom wall of the dispenser body 2 so as to be surely sealed when closed by the valve body 5d. Has been.

  Reference numeral 7 denotes a cover for sandwiching and fixing the pourer body 2 to the mouth portion 1a of the container 1 at its side wall edge (engagement by screws or undercut). The cover 7 has an opening 7a that exposes the head 3a of the rod 3 and the dispensing nozzle 4, and the top plate 7b functions as a stopper that abuts against the partition wall 5 and regulates its moving range.

  Reference numeral 8 denotes an overcap that covers the rod 3 and the dispensing nozzle 4 together with the cover 7. The overcap 8 is engaged and held in the mouth portion 1a of the container 1 by screws or undercuts, and an inner wall (top wall) thereof is connected to an engagement portion 4b formed at the tip of the dispensing nozzle 4. It has an engaging projection 8a that can be engaged and lifted (moved forward) the dispensing nozzle 4 when the overcap 8 is removed. The engaging projections 8a can be formed by a cylindrical body suspended from the inner wall (top wall) of the overcap 8, but a plurality of plate-like pieces are arranged and suspended in an annular manner. However, this point is not limited.

  When the overcap 8 is removed, as shown in FIG. 3, the dispensing nozzle 4 is pulled up together with the partition wall 5 (forward movement), the path k of the dispensing nozzle 4 is closed, and the passage 6 is opened.

  In this state, when the container 1 is inverted, the contents in the container 1 flow into the measuring space m through the passage 6, and the weighing is completed by filling the measuring space m with the contents.

  After the measurement is completed, as shown in FIG. 4, the dispensing nozzle 4 is pressed at the application site while maintaining the posture. Then, the pouring nozzle 4 moves backward, the path k is opened, the passage 6 is closed by the valve body 5d, and only the contents in the measurement space m are poured out through the path k.

  As described above, the quantitative dispenser according to the present invention basically includes the dispenser nozzle 4 having the partition wall 5, the dispenser body 2 that forms the partition recess c, and the dispenser body 2 in the container 1. It can be constructed with a cover 7 that is clamped and fixed at the mouth 1a, requires only a small number of parts, and can be easily assembled because the structure can be simplified, and the contents involved in weighing Can only be poured out reliably.

  All of the components of the dispenser can be molded from synthetic resin, and can be applied to containers for cosmetics, seasonings, etc., as well as hair restorer chemicals.
