Description

[0001]
[Industrial applications]
The present invention relates to a measuring cap having a function of measuring and discharging contents from a container.
[0002]
[Prior art]
A measuring cap is used when it is necessary to dispense a certain amount of detergent and softener from a container.
[0003]
In this method, a cap for closing a mouth of a container for storing liquid contents is constituted by an inner plug and a cap body for opening and closing the cap, and the cap body has a function as a measuring cup.
[0004]
Various developments have hitherto been made in order to meet the need for varying the amount of liquid to be measured.
[Patent Document 1] Japanese Patent Application Laid-Open No. 9-301407 [Patent Document 2] Japanese Patent Application Laid-Open No. 61-104962
However, in the conventional measuring cap, the maximum value of the volume is fixed and the volume is relatively small, so that it cannot be applied to the measurement of a liquid content liquid which is discharged at a time.
[0005]
That is, as shown in FIG. 3, the measuring cap 101 divides the inner space 110 having a height h between the lower end 119 of the straight cylindrical body 115 of the cap body 113 and the top plate 116 which engages with and disengages from the inner plug 102. However, the diameter D of the trunk is substantially constant from the top to the bottom, and the volume formed by the product of the cross-sectional area and the height of the trunk cannot be increased. Further, a gap having a width W between the inner plug 102 and the cap body 113 is not effectively used as a measuring volume. The reason that the diameter of the body portion is constant and maximum at the lower end 119 is a straight-tube shape is a method of maximizing the inner volume of the cap main body within a range in which the mold can be removed at the time of molding, which is a limitation in manufacturing. Due to restrictions, a space that cannot be effectively used for measurement purposes is left in the inner plug.
[0006]
The present invention has been made in view of the above-described circumstances, and can effectively utilize the space in an inner plug to have a large capacity in a cap body for the purpose of measurement, and therefore a large-capacity liquid. It is an object of the present invention to provide a measuring cap having a simple structure while solving the limitations on manufacturing while enabling measurement of the measuring cap.
[0007]
