In the container 10, for example, the container body 11, the cap body lower portion 21 of the cap body 13,
The cap body upper part 22 and the cover cap 14 are made of polypropylene, and the dip tube 18 and the seal ring 23 are made of low density polyethylene (LDPE).

Then, the spout member 17 is made of a flexible material (for example, low density polyethylene (LDPE)) having a higher water repellency than the material (for example, polypropylene) for forming the upper portion 22 of the cap body, and the spout 17A is formed. The curled edge 17C is resin-molded at the edge portion in the liquid pouring direction (A).

Next, the usage of the container 10 will be described. (1) After filling the container body 11 with contents, the container body 11
The cap 12 is screwed into the opening 11A.

(2) When pouring out the contents from the container body 11, the cover cap 14 is rotated around the hinges 19A and 19B. Then, the user pressurizes the container body 11 to transfer the contents to the dip tube 1
8. Push out from the nozzle 16 into the measuring chamber 15. Weighing room 15
After measuring a certain amount of the contents, the container body 11 is tilted, and the contents in the measuring chamber 15 are poured out from the spout 17A.

Fill. At this time, the cap 12 removed from the container body 11 is inverted, that is, placed on a table or the like with the top surface 14A of the cover cap 14 as a placement surface (FIG. 4).

The operation of this embodiment will be described below. (1) When pouring out the contents in the measuring chamber 15 from the pouring outlet 17A, the dripping of the contents around the pouring outlet 17A
It is restrained by the liquid receiving portion 32 surrounded by the dripping prevention weir 31, and then returned to the measuring chamber 15 from the liquid return port 33. For this reason, the dripping does not randomly flow from around the spout 17A to a wide range on the outer surface of the cap body 13, and the measuring cap 12 and the container body 11 are not contaminated.

(2) The liquid return port 33 of the liquid receiving part 32 is the spout 1
Since it is arranged at the position opposite to the liquid pouring direction A from 7A, when the liquid is poured out by inclining the container body 11 in the liquid pouring direction A,
The liquid in the measuring chamber 15 is prevented from leaking from the liquid return port 33 to the liquid receiving portion 32 side, and the liquid in the measuring chamber 15 can be reliably poured out from the pouring port 17A.

(3) Ceiling 15 of the measuring chamber of the cap body 13
The portion around the spout 17A of B is the bottom of the liquid receiving portion 32,
The portion around the liquid receiving portion 32 of the ceiling portion 15B of the measuring chamber is connected to the liquid receiving portion 3
It is assumed to be raised to the bottom of No. 2 through a step. Therefore, the ceiling height of the measuring chamber ceiling portion 15B is set to the liquid receiving portion 3
It is possible to mitigate a strong collision of the liquid, which becomes higher in the area around the two and is pushed out from the nozzle 16 toward the measuring chamber 15 side, to the measuring chamber ceiling portion 15B. For this reason, it is possible to prevent the liquid extruded from the nozzle 16 to the measuring chamber 15 side from scattering and forming a foam.

(4) The discharge port 16A of the nozzle 16 is arranged at a position opposite to the liquid pouring direction A from the pouring port 17A. For this reason, the residual liquid remaining in the nozzle 16 or the dip tube 18 after the measurement causes the discharge port 1 of the nozzle 16 when the liquid is poured out by inclining the container body 11 in the liquid pouring direction A.
6A can be prevented from leaking into the measuring chamber 15, and the measuring accuracy can be improved.

(5) The cap body 13 was divided into a cap body lower portion 21 and a cap body upper portion 22, and the cap body upper portion 22 was attached around the cap body lower portion 21 in an overlapping manner. Therefore, even when it is indispensable that the upper part 22 of the cap body is made of a transparent material for measuring the content, the container body adhered part (outer ring 22A) of the upper part 22 of the cap body is on the back side of the cap body. The appearance is improved by reflecting the color of the lower portion 21. Further, the external appearance of the transparent weighing scale portion 22C of the cap body upper portion 22 and the container body adhered portion (outer ring 22A) reflecting the color of the cap body lower portion 21 becomes clear, and the weighing scale portion 22C The distinctiveness can also be improved.

(6) When the material for forming the cap body 13 is, for example, polypropylene, the material for forming the spout member 17 is different from the material for forming the cap body 13 and has high water repellency, for example, low density polyethylene. As a result, the spout 17A has good drainage due to the high water repellency of the material. Therefore, by tilting the container body 11,
The liquid that has reached the spout 17A is quickly separated from the edge of the spout 17A and is poured out. Therefore, there is no possibility that drips flow around the cap body 13 and stain the cap body 13 and the container body 11.

(7) The material for forming the spout 17 (for example, low-density polyethylene) is more flexible than the material for forming the cap body 13 (for example, polypropylene), and the spout 17A
A curled edge 17C is formed by resin molding at the edge of the liquid pouring direction. Therefore, even if the curled edge 17C is forcibly removed from the mold, the curling edge 17C is not damaged due to its flexibility, and the spout 17A having the curled edge 17C with good liquid drainage can be configured. .

(8) Bottom 15A of the measuring chamber of the cap body 13
Are projected outward from the container body adhered portion (outer ring 21A) of the cap body 13. Therefore, when expanding the volume of the measuring chamber 15, the measuring chamber bottom portion 15A of the cap body 13 is projected outward (downward) by the amount of the expanding volume of the measuring chamber 15, and the protruding portion is stored in the container body 11. Can be stored.

(9) In the above (1), the cap body 1
The height of the portion (the head-equivalent portion) located outside the container body 11 of 3 is not changed at all, and only the height of the portion of the cap body 13 accommodated in the container body 11 is increased. Therefore, even if the volume of the measuring chamber is expanded, the container body 1 of the cap body 13 is
It is possible to improve the appearance of the entire container 10 without increasing the ratio of the height of the portion located outside 1 to the height of the container body 11.

(10) In the above (1), even if the volume of the measuring chamber is expanded, the height of the portion of the cap body 13 located outside the container body 11 does not increase. Therefore, the container 1 can be stored without increasing the size of the storage box or the display shelf of the container 10.
0 is easy to handle.

(11) Bottom 15A of the measuring chamber of the cap body 13
A weir 35 for preventing dripping when the cap is removed and inverted is provided around the dip tube 18 on the outer surface of the. Therefore, the cap body 13 removed from the container body 11 at the time of refilling the contents is in the inverted state, that is, the cover cap 14
When the top surface 14A of the cap is placed on a table or the like as a mounting surface, even if the residual contents attached around the dip tube 18 are transmitted to the outer surface of the bottom 15A of the measuring chamber of the cap body 13, the liquid is prevented from dripping. The weir 35 prevents the spread of dripping. Accordingly, it is possible to prevent the drips from polluting the outer peripheral portion of the main body of the cap 12 and the periphery of the table surface or the like on which the cap 12 is placed.
