DETAILED DESCRIPTION OF THE INVENTION
As shown in FIG. 1, the valve-equipped container 10 such as a detergent container has a cap 20 attached to the container body 11. The cap 20 includes a cap body 21 attached to the opening 12 of the container body 11 by fitting (or screwing) or the like, and a cover cap 22 attached to or detached from the cap body 21 by screwing (or fitting) or the like. Have. The cover cap 22 is used as a measuring cap that receives and measures the internal solution poured out from the cap body 21.
[0007]
The cap 20 is an assembly in which a valve protection member 50 that supports a pendulum valve 40, which will be described later, is fitted to the cap main body 21 and a cover cap 22 is attached to the cap main body 21, and the container main body filled with the internal solution. 11 is used.
[0008]
The cap body 21 includes an outer cylinder 31 attached to the opening 12 of the container body 11, a top surface part 32 that closes the upper end of the outer cylinder 31, a first inner cylinder 33 that follows the inner periphery of the top surface part 32, A threaded portion 34 provided on the upper surface of the top surface portion 32 to which the cover cap 22 is screwed, a partition portion 35 that is connected to the first inner cylinder 33 and partitions the inside and outside of the cap body 21, and extends downward from the partition portion 35. A second inner cylinder 36 and an extraction cylinder 37 extending upward from the second inner cylinder 36 via the partition portion 35 are provided.
[0009]
The second inner cylinder 36 of the cap body 21 has a cylindrical shape that protrudes into the container body 11 and includes a circulation port 36A for taking in and out the inner solution. The dispensing cylinder 37 guides the internal solution taken from the flow port 36A of the second inner cylinder 36 and pours it out from the spout 37A. The cap main body 21 forms an annular liquid recovery part 38 on the partition part 35 between the first inner cylinder 33 and the extraction cylinder 37, and the extraction cylinder 37 is arranged on the side opposite to the extraction cylinder 37. The liquid return slit 39A and the liquid return port 39B of the liquid recovery part 38 are opened so as to be continuous with each other.
[0010]
