  However, the measuring caps of Patent Documents 1 and 2 are formed in a cylindrical shape or the like so that the liquid is poured out. A large amount of liquid also flowed out around the soiled area of the wash, and it was difficult to pour out an appropriate amount of liquid only to the area of the soiled area of the wash. In addition, the measuring cap of Patent Document 3 has a hexagonal shape on the inner surface side of the inner cylinder portion. Therefore, the capacity of the cap is reduced, and the cap is enlarged to measure a large amount of liquid, or a plurality of times. Weighing is required. Moreover, although the inner surface side of the entrance / exit portion has a hexagonal and angular apex, the outer surface shape is circular, so that it is difficult to pour out little by little to a target location such as a soiled portion of the wash.

  Accordingly, the present invention has been made to solve the above-described problems, and even when the viscosity of the liquid is high, a measuring cap that can easily and surely pour the liquid only into a portion such as a soiled portion of the washing item. And a liquid container.

A pouring part bent into a V-shape is formed, and the cylindrical wall of the inner cylinder part provides a measuring cap whose upper and lower shapes are formed in substantially the same shape with the annular wall as a boundary. In addition, the cylindrical wall of the inner cylinder part has a cylindrical part with a substantially arc-shaped cross section, and the end opposite to the pouring part having a substantially V-shaped cross section in which two flat surfaces are connected is crossed. Since it connects with the edge part of the cylindrical part of a substantially circular arc shape, it becomes easy to pour a liquid toward the top part of the V-shape of a pouring part.

  Moreover, this invention provides the liquid container provided with the container main body which accommodates a liquid, and the above-mentioned measuring cap attached to the opening part of this container main body so that attachment or detachment is possible.

  According to the present invention, the inner cylinder part is partially provided with an extraction part having a substantially V-shaped cross section, so that when the user pours liquid from the inner cylinder part of the measuring cap, a small amount is extracted. Therefore, an appropriate amount of liquid can be easily and reliably poured out and attached only to a portion such as a soiled portion of the wash. Moreover, since it has the plane part which forms cross-sectional substantially V shape, it becomes easy to see the inside of a cap at the time of measurement.

  A measuring cap 1 according to the present invention is a double cylinder-shaped cap having an outer cylinder part 2 and an inner cylinder part 3, and the cylindrical wall 4 of the inner cylinder part 3 is partially bent in a substantially V-shaped cross section. It is characterized by having the extraction | pouring part 9 integrally formed by doing. More specifically, in the measuring cap 1 of the present embodiment, the cylindrical wall 4 of the inner cylindrical portion 3 has a substantially V-shaped cross section by bending at two flat portions 9a and 9a, part of which is continuous. This portion is a pouring portion 9 used as a liquid flow path when the liquid A is poured out from the cap 1. Moreover, as shown in FIG. 4, the angle (θ) of two continuous flat portions 9a, 9a of the extraction portion 9 having a substantially V-shaped cross section is set within a range of 50 ° to 150 ° ( Preferably 60 ° to 130 °, particularly preferably 90 ° to 120 °).

  Further, two continuous flat portions 9a, 9a of the pouring portion 9 of the cylindrical wall 4 are formed symmetrically with respect to the V-shaped top portion 9b as a boundary, and the bowl-shaped pouring of the container body 20 is performed. Due to the size relationship of the protruding portion 32, the cylindrical wall 4 is formed in a size that fits within the diameter of the circumscribed circle of the cylindrical portion 10 having a substantially arc-shaped cross section.

  Further, the cylindrical wall 4 of the inner cylindrical portion 3 of the measuring cap 1 has a cylindrical portion 10 having a substantially arc-shaped cross section at a portion other than the pouring portion 9 having a substantially V-shaped cross section. That is, both ends of the cylindrical portion 10 having a substantially arc-shaped cross section are connected to opposite ends of the two connecting flat portions 9a and 9a. And since the cylindrical part 10 is a cross-section substantially circular arc shape, when the extraction | pouring part 9 is inclined, the liquid A becomes easy to gather in the V-shaped top part 9b of the extraction | pouring part 9, and the extraction property is easy. It has come to improve. Further, a sufficient capacity can be ensured without enlarging the inner cylinder part more than necessary.

  Furthermore, as shown in FIG. 1, the cylindrical wall 4 of the inner cylinder portion 3 is formed in substantially the same shape in the vertical direction with the annular wall 5 as a boundary. That is, the inner cylinder part 4 on the opening end 3a side and the bottom part 3b side of the inner cylinder part 3 protrudes in the axial direction from the outer cylinder part 2 with the annular wall 5 as a boundary, and the inner cylinder part 3 on the opening end 3a side The outer shape and inner shape of the cylindrical wall 4 and the outer shape and inner shape of the cylindrical wall 4 of the inner cylindrical portion 3 on the bottom 3b side are formed in substantially the same shape. Moreover, the cylindrical wall 4 of the inner cylinder part 3 can be formed in the substantially uniform thickness over the perimeter.

  Furthermore, the open end 3a of the inner cylinder part 3 has only two extraction parts 9 having a substantially V-shaped cross section, two continuous plane parts 9a, 9a including the extraction part 9, The entire circumference of the extraction portion 9 and the cylindrical portion 10 may be partially expanded outward in a round shape.

  In addition, the diameter of the outer cylinder part 2 is formed in the magnitude | size which a user can grip easily. Moreover, as shown in FIGS. 1 and 2, a knurling can be formed on the outer surface of the cylindrical wall of the outer cylinder portion 2 to make it difficult to slip. Further, as shown in FIG. 1, the inner cylinder portion 3 is appropriately graduated.

  As shown in FIG. 5, the liquid container 100 includes a container body 20 that stores the liquid A, and a measuring cap 1 that is detachably attached to the mouth portion 21 of the container body 20. Examples of the liquid A include a liquid detergent containing a surfactant, a liquid softener, and a bleaching agent. The measuring cap 1 of the present invention is effective not only when the physical properties of the liquid are low viscosity, but also particularly when the stringing and viscosity properties are high and the liquid does not easily break. For example, the liquid A is 25 The viscosity at 50 ° C. is 50 to 2000 mPa · s (B-type viscometer, rotation speed 60 rpm, rotor No. 3), particularly preferably 100 to 1000 mPa · s, and the viscosity change between 5 ° C. and 25 ° C. (Vis ( 5 ° C.) / Vis (25 ° C.) is preferably 1.5 or more and 8 or less.

  When using the liquid container 100 of the present embodiment, first, the liquid A is poured out from the container body 20 into the inner cylindrical portion 3 of the measuring cap 1, and then the cap 1 is tilted as shown in FIG. Liquid A is poured into, for example, a dirty part of the wash. At this time, an extraction portion 9 having a substantially V-shaped cross section is provided in a part of the cylindrical wall 4 of the inner cylinder portion 3 by two continuous flat portions 9a, 9a. A small amount can be extracted by the V-shaped top portion 9b of the letter-shaped pouring portion 9, and an appropriate amount of the liquid A can be easily and reliably poured and attached only to a portion such as a dirty portion of the washing.

  Moreover, in this measuring cap 1, the opening end 3a side and the bottom part 3b side of the inner cylinder part 3 protrude in the axial direction from the outer cylinder part 2, respectively, and the outer shape of the cylindrical wall 4 of the inner cylinder part 3 on the opening end 3a side. The outer shape and the inner shape of the cylindrical wall 4 of the inner cylindrical portion 3 on the bottom 3b side are formed in substantially the same shape. Accordingly, the user of the measuring cap 1 can easily confirm the shape position of the dispensing portion 9 at a glance from when the measuring cap 1 is mounted on the container body 20. Further, when the liquid A is poured out using the measuring cap 1, the liquid A can be surely poured out from the pouring portion 9 of the measuring cap 1 little by little to a predetermined applied place. Further, the liquid A adhering to the inner side of the cylindrical wall 4 of the inner cylindrical portion 3 is concentrated on the V-shaped top portion 9b of the pouring portion 9 through the flat portion from the arc-shaped portion, and more reliably. Liquid A can be collected. Furthermore, since the open end 3a of the inner cylinder part 3 has an arcuate part in the outer shape of the cylindrical part 4, the open end 3a of the measuring cap 1 is provided when the inner cap 30 is arranged on the container body 20. However, the liquid A collected at the bottom of the inner plug 30 can be recovered from the return hole 33.
