The rib portion 31C is disposed with a gap in the circumferential direction, the lower end edge of the rib portion 31C is in contact with or close to the slide member 5, and the rear end edge of the rib portion 31C is on the outer cylinder portion 32. It is connected continuously.

  The outer cylinder part 32 has a long cylindrical shape that is long in the front-rear direction in plan view, and covers a part of the square cylinder part 12 of the cap body 4 and the exposed part of the slide member 5 from the outside in the radial direction. . As shown in FIGS. 3 and 4, the lower end edges of the left and right wall portions of the outer cylinder portion 32 are inclined so as to gradually go downward as going backward.

  The biasing spring 7 is disposed between the front wall portion 15 of the rectangular tube portion 12 and the partition plate portion 22 of the slide main body portion 21 and biases the slide member 5 rearward. Instead of the urging spring 7 formed of a coil spring, the slide member 5 such as a spring formed in a bellows shape in a plan view by bending a rod having a rectangular cross section alternately in the front-rear direction is moved backward. Other urging means may be used as long as it can be urged toward.

Next, a method of using the measuring cap 1 having the above configuration will be described.
First, as shown in FIG. 1, when the lid member 6 is attached to the cap body 4, the exposed portion of the cap body 4 is covered. Therefore, even if an external force is unexpectedly applied to the measuring cap 1, it slides. The member 5 cannot be pushed forward. Therefore, in the state where the lid member 6 is mounted on the cap body 4, the contents in the container body 2 are not discharged.
Here, the plug portion 31 </ b> A and the fitting cylinder portion 31 </ b> B of the top wall portion 31 are fitted separately from the extraction cylinder portion 18 </ b> B and the attachment cylinder portion 18 </ b> C of the cap body 4, and the lid member 6 is attached to the cap body 4. Since it is firmly attached, even if an unexpected external force is applied to the outer cylindrical portion 32 of the lid member 6, the lid member 6 is unlikely to be detached by this external force. Moreover, the rib part 31C is arrange | positioned in the rear-end part of the top wall part 31, and the rear-end part of the outer cylinder part 32 becomes difficult to deform | transform toward the front. Thereby, it becomes difficult for unexpected external force to be applied to the slide member 5, and the slide member 5 is suppressed from being pushed forward by this external force.

  When discharging the contents in the container body 2, the lid member 6 is first removed from the cap body 4 as shown in FIG. 6. And the container main body 2 with which the measurement cap 1 was mounted | worn is turned upside down in the state which hold | gripped the container main body 2, and it is set as the inverted posture which the measurement cap 1 faces below. Thereby, the contents accommodated in the container main body 2 flow out of the container main body 2 through the stock hole 13A, and are guided into the stock chamber 5A through the lower surface opening 25A. Thereby, the contents in the container body 2 are stocked in the stock chamber 5A.

  When a predetermined amount of contents is stocked in the stock chamber 5A, the slide member 5 is pushed forward into the rectangular tube portion 12. When the slide member 5 is pushed in, the slide member 5 slides forward. When the slide member 5 slides toward the take-out position, the lower surface opening 25A of the slide member 5 is displaced in the front-rear direction with respect to the stock hole 13A of the cap body 4, and the upper surface opening 28A and the lower surface opening of the slide member 5 are shifted. The portion 25A is closed by the rectangular tube portion 12. Thereby, the communication between the stock chamber 5A and the outside of the slide member 5 is blocked, the contents are prevented from being opened to the outside from the stock chamber 5A, and the contents are stocked in the stock chamber 5A, A predetermined amount of contents are stored in the stock chamber 5A.

  Here, since the protruding portion 22B is provided, the stock chamber 5A communicates with the take-out hole portion 18A via the upper surface opening portion 28A in a state where the stock chamber 5A communicates with the stock hole portion 13A via the lower surface opening portion 25A. The upper surface opening 28A is opened before the lower surface opening 25A is completely closed, and the contents stored in the stock chamber 5A are prevented from being discharged through the extraction hole 18A. doing. Accordingly, a predetermined amount of contents can be stored in the stock chamber 5A, and the contents can be accurately measured.

  When the slide member 5 is further pushed toward the take-out position and positioned at the take-out position, the take-out hole 18A of the cap body 4 and the upper surface opening 28A of the slide member 5 are moved in the front-rear direction as shown in FIG. The extraction hole 18A and the upper opening 28A overlap in plan view. As a result, the stock chamber 5A communicates with the outside of the cap body 4 via the upper surface opening 28A and the extraction hole 18A. Therefore, the contents in the stock chamber 5A are discharged to the outside of the cap main body 4 through the inside of the extraction cylinder portion 18B via the upper surface opening portion 28A and the extraction hole portion 18A.

After the contents in the stock chamber 5A are discharged, the pressing of the slide member 5 is released. The slide member 5 is slid rearward from the take-out position toward the stock position by the restoring deformation of the biasing spring 7.
When the first engaging protrusions 16A and 17A of the side wall parts 16 and 17 are engaged with the second engaging protrusions 26A and 27A of the side plate parts 26 and 27, they are biased rearward by the biasing spring 7. The slide member 5 is prevented from sliding backward beyond the stock position.
As described above, the contents stored in the container body 2 are weighed out.

  According to the measuring cap 1 configured as described above, the lid member 6 covers the portion of the slide member 5 that is exposed rearward from the cap body 4, and the lid member 6 is attached to the slide member 5 when the lid member 6 is attached. Since no external force is applied, the contents in the container main body 2 can be prevented from being discharged by an unexpected external force applied to the measuring cap 1.

In addition, this invention is not limited to the said embodiment, A various change can be added in the range which does not deviate from the meaning of this invention.
For example, the lid member covers a portion of the slide member exposed from the cap body and a part of the cap body, but it is sufficient that at least the exposed portion of the slide member is covered.
The slide axis may not be orthogonal as long as it intersects the container axis.
In the slide member, the closing plate portion is fitted in the rear end portion of the slide main body portion, but the closing plate portion may not be provided. The slide member has a rectangular cylindrical shape, but may have other shapes such as a solid column shape as long as the stock chamber is defined.
Although an urging member such as an urging spring for urging the slide member rearward is provided, the urging member may not be provided.
The slide member is formed with the stock hole portion rearward than the take-out hole portion and urged rearward toward the stock position by the biasing spring, while the stock hole portion is formed forward with respect to the take-out hole portion. The biasing spring may be biased backward toward the take-out position.

  According to this invention, industrial applicability is recognized regarding the measuring cap which can prevent the contents from being discharged by an external force applied unexpectedly.
