It is preferable to provide a recess that is detachably fitted to the head of the nozzle, and the engagement allowance for the container is larger than the stroke of the nozzle.

  The contents can be weighed, poured out, and applied with a simple operation of sliding the nozzles alternately.

Hereinafter, the present invention will be described more specifically with reference to the drawings.
FIG. 1 shows an embodiment of a metering type application container according to the present invention, and this container is made of a synthetic resin.

  In the figure, reference numeral 1 denotes a container body having a squeezable body portion, and inside the container body 2, 2 is an inner plug that fits and seals with the mouth 1 a of the container body 1, and 3 extends to the bottom of the container body 1. Suction tube 4 having a front end and a rear end connected to the inner plug 2 stands up on the outer surface of the inner plug 2 (may be formed integrally with the inner plug 2 or formed separately) It is a cylindrical body. This cylinder 4 has a passage 4 a connected to the suction pipe 3.

  Reference numeral 5 denotes a cover for accommodating the cylindrical body 4 and the inner plug 2 on the inner side to form a measuring space K. The cover 5 has an opening 5a (through hole) at its tip, and its rear end is fixedly held on the outer wall of the mouth portion 1a of the container body 1 by screw fitting (or undercut fitting).

  Reference numeral 6 denotes a nozzle for pouring out and applying contents related to measurement. The nozzle 6 has a body 6b that is slidably fitted to the outside of the cylinder 4 and slides in a liquid-tight state with the head 6a exposed at the opening 5a of the cover 5. Moreover, the head 6a of this nozzle 6 is made into the shape which bulges the outer periphery of the edge part outside.

  7 is a first passage that slides the nozzle 6 away from the inner plug 2 and connects the passage 4a of the cylindrical body 4 and the measuring space K at the stroke end (hereinafter referred to as top dead center). Is a second passage that slides in a direction approaching the inner plug 2 and connects the dispensing space 6c of the nozzle 6 and the measuring space K at the stroke end (hereinafter referred to as bottom dead center).

  Further, at the top dead center of the nozzle 6, an air discharge portion p that allows only air in the measurement space K to flow is formed between the opening 5 a of the cover 5 and the nozzle 6. In the present embodiment, the air discharge portion p is constituted by a narrow groove 5b provided in a downward step portion with which the partition wall of the nozzle 6 formed around the lower end of the opening 5a abuts (see an enlarged view of FIG. 2).

  When the passage 4a of the cylindrical body 4 communicates with the measuring space K in the first passage 7, the dispensing path 6a of the nozzle 6 and the measuring space K are blocked so that the contents cannot pass through. On the contrary, when the dispensing path 6c of the nozzle 6 and the measuring space K are in communication, the passage 4a of the cylindrical body 4 and the measuring space K are convex portions formed on the lower surface of the partition wall located immediately above the passage 7 of the nozzle 6. The cylinder 4 is in a state of being blocked by insertion into the passage 4 a and contact between the lower surface of the partition wall and the end surface of the cylinder 4.

  Further, reference numeral 9 denotes an overcap that covers the nozzle 6 together with the cover 5 and is engaged and held on the outer wall of the mouth of the container body 1 by screw fitting or the like. The overcap 9 is formed with a cylindrical portion that hangs downward on the inner side of the top wall 9a, and a concave portion that is detachably fitted to the bulging portion of the head 6a of the nozzle 6 by an undercut. 9b is provided and has an engagement allowance larger than the stroke when the nozzle 6 slides. It should be noted that the tip of the cylindrical portion forming the recess 9b has a length so as to be in close contact with the peripheral wall portion of the opening 5a of the cover 5 and the wall rising from the outer periphery of the wall portion when the overcap 9 is engaged. Is set.

  In the state shown in FIG. 1 with the overcap 9 attached, the nozzle 6 is located at the bottom dead center, and the passage 4a of the cylindrical body 4 and the measuring space K are in a state of being shut off. Even if the body is squeezed, the contents in the container are not discharged into the measuring space K.

  When the overcap 9 is rotated to remove the overcap 9, the nozzle 6 with the bulging portion fitted in the recess 9b slides away from the inner plug 2 together with the overcap 9, as shown in FIG. Thus, the top cap is reached, and then the overcap 9 is removed.

  When the nozzle 6 reaches the top dead center, the passage 4a of the cylindrical body 4 and the measuring space K are communicated with each other by the first passage 7, and the contents in the container body 1 are obtained by appropriately squeezing the body portion of the container body 1. The object is discharged into the measuring space K through the suction pipe 3, the cylinder 4 and the first passage 7. At this time, the air existing in the measurement space K is discharged to the outside from the air discharge portion p that allows only air to flow between the cover opening and the nozzle as the contents are discharged into the measurement space K. .

  In this state, the second passage 8 is located outside the cover 5, and the dispensing path 6c of the nozzle 6 and the measuring space K are configured so that only air can flow between the cover opening and the nozzle. Since the object is blocked, even if the container body 1 is reversed, it does not leak even if the contents related to the measurement exist in the measurement space K.

  In order to pour out and apply the contents in the measuring space K through the nozzle 6, the head 6a of the nozzle 6 is brought into contact with the application site and the nozzle 6 is pushed in (the nozzle 6 is slid toward the inner plug 2). .

  Then, as shown in FIG. 3, the second passage 8 is located inside the cover 5, the extraction passage 6 c of the nozzle 6 and the measurement space K communicate with each other through the second passage 8, and the contents in the measurement space K are It is quickly dispensed through the second passage 8 and the dispensing passage 6c.

  In this state, the passage 4a of the cylindrical body 4 and the measurement space K are blocked, so that the contents in the container body 1 never flow out into the measurement space K.

  Since the container body 1 has a body that can be squeezed, the measuring-type application container having the above-described configuration can be operated in an upright state without inverting the container body 1, and the nozzle in the same state. Since the contents in the container body 1 can be measured, poured out and applied only by sliding the 6 to the top dead center or the bottom dead center, it is very convenient to use, and the number of parts is small and the structure is simplified.

  In this embodiment, the first passage 7 and the second passage 8 are shown as an example of an opening that penetrates the side wall of the nozzle 6. However, when the nozzle 6 is slid, one of the passages will be opened. As long as one is closed, it is not limited to the illustrated one.

  In addition, the air discharge part p should just be formed at least 1 place, and is not restricted to the above-mentioned Example. For example, instead of the narrow groove 5b formed in the downward step portion around the lower end of the opening 5a, a protrusion may be formed, or a narrow groove or a protrusion may be formed on the partition wall side of the nozzle 6, or the nozzle 6 A method of forming a rough surface on at least one of the contact portions between the partition wall and the periphery of the opening 5a is also possible. Further, although not shown, an opening that allows only the air in the measurement space K to be exhausted is formed in the nozzle 6 or the cover 5, or a valve mechanism that opens only outward is added to the opening. Also good.

  It is possible to provide an easy-to-use metering type application container capable of measuring, pouring, and applying contents with a simple operation of sliding nozzles alternately.

It is the figure which showed embodiment of the measurement type application container according to this invention. It is the figure which showed the state which removed the overcap in the container shown in FIG. It is the figure which showed the state which is pouring out and applying the content concerning measurement using the container shown in FIG.
