BACKGROUND OF THE INVENTION
The present invention relates to a measuring cap, and more particularly to a measuring cap that is detachably attached to a mouthpiece of a container body or a body cap attached to the mouthpiece.
[0002]
[Prior art]
For example, containers containing liquid detergent or the like as content liquids may be used while measuring these content liquids, and it is cumbersome to use a measuring cup or the like separately. For example, a measuring cap having a function is attached to a mouth portion of a synthetic resin bottle container or the like. The measuring cap is equipped with a scale, etc., so that an appropriate amount can be easily measured according to the type and usage of the content liquid. It is necessary to prevent dripping when attaching to the mouth.
[0003]
As a measuring cap designed to prevent dripping when reattached to the mouth, for example, a male screw is provided outside the tip of the measuring cap so that the spout is inserted inside the mouth or the body cap. (For example, see Patent Document 1), a body cap having a liquid recovery recess that can be inserted from above into the spout portion of the measuring cap is attached to the mouth portion and poured into the liquid recovery recess. A device in which a measuring cap is attached to a main body cap while inserting a mouth is known (see, for example, Patent Document 2).

[Problems to be solved by the invention]
Since the conventional measuring cap is a synthetic resin cap mainly formed by injection molding, the cross-sectional shape of the liquid reservoir part of the measuring cap is the cross-section of the spout part, for ease of removal of the mold during molding, etc. It was constrained by the shape, and it was necessary to make the shape equal to or smaller than this. Therefore, according to the measuring cap in which the conventional spout part is inserted and arranged inside the neck part of the container or the inside of the main body cap, when the capacity of the liquid reservoir part is increased in order to increase the measurable amount For example, as shown in Patent Documents 1 and 2, it is necessary to increase the protruding length from the neck portion of the measuring cap with a cross-section equivalent to the spout portion, which is bulky in the height direction and is unsatisfactory in appearance. It becomes easy to give a stable impression. Further, when trying to increase the capacity by expanding the diameter of the spout part of the measuring cap in the transverse direction, the neck part and the body cap into which the spout part is inserted also need to be expanded in the transverse direction. The amount of resin used when forming the main body cap will increase.
[0006]
The present invention is capable of measuring with a measuring cap by increasing the capacity of the liquid reservoir without excessively extending the protruding length from the mouth and without expanding the diameter of the neck or body cap in the transverse direction. An object of the present invention is to provide a measuring cap capable of easily increasing the capacity.
[0007]
[Means for Solving the Problems]
The present invention is a measuring cap that is detachably attached to a mouthpiece part of a container body or a body cap attached to the mouthpiece part. A liquid return cylinder part in which at least a part on the tip side is inserted and arranged inside the cap, and a liquid reservoir bulge part having an inner diameter larger than the inner diameter of the liquid return cylinder part connected to the liquid return cylinder part; The above-mentioned object is achieved by providing a measuring cap that is formed by injection molding of a lower member and an upper member that are divided into upper and lower parts and integrated via an annular joint.
[0008]
Here, in the above description, the inner diameter of the liquid reservoir bulging portion compared with the inner diameter of the liquid return cylinder portion means the inner diameter of the trunk portion in the liquid reservoir bulging portion. It suffices to have at least a part having a larger inner diameter than the inner diameter of the return cylinder part. The inner diameter means the diameter of the liquid return cylinder or the liquid reservoir bulge when the cross-sectional shape is circular, and when the cross-sectional shape is other than circular, the secondary radius of the cross-section of the cross-sectional shape. Means twice as much.
