The present invention relates to a measuring cap.

Examples of the measuring caps that are detachably attached to the mouth portion of the container body or the body cap attached to the mouth portion include those described in Patent Documents 1 and 2.

The measuring cap described in Patent Document 1 includes a lower member having a spout provided on the lower end side and a liquid return cylinder portion inserted into the mouth portion of the container body or the inside of the body cap from above, and a lower member. It has an upper member having a ceiling-shaped liquid reservoir that is attached to the liquid return cylinder portion, and the upper outer peripheral surface of the lower member is fitted inside the upper member to return the liquid to the lower member. The outer peripheral surface of the upper annular wall in the tubular portion is fitted and joined to the inside of the bulging joint skirt portion provided in the lower portion in the liquid reservoir portion of the upper member.

In the measuring cap described in Patent Document 1, the outer peripheral surface of the upper outer peripheral wall in the liquid return cylinder portion of the lower member is inside the bulging joint skirt portion provided at the lower part in the liquid reservoir portion of the upper member. It is fitted and joined. As a result, the measuring cap forms a stepped portion on the outer peripheral surface of the liquid reservoir portion of the upper member due to the bulging of the joint skirt portion at the intermediate portion in the vertical direction. The above-mentioned stepped portion formed on the outer peripheral surface of the liquid reservoir portion of the upper member may make it difficult for some users to grip the measuring cap, which may impair the measuring workability.

On the other hand, the measuring cap described in Patent Document 2 is made to improve the above-mentioned difficulty of gripping in the measuring cap described in Patent Document 1, and the upper member is lowered over the entire length in the vertical direction. It is assumed that the outer peripheral surface of the upper member is fitted to the outside of the upper outer peripheral surface of the member, and the outer peripheral surface of the upper member forms a continuous surface over the entire length in the vertical direction.

According to the measuring cap described in Patent Document 2, when the user grasps the measuring cap, the user puts his / her finger on a continuous surface having no step over the entire length of the upper member in the vertical direction, and the upper member Will grab. Compared to a measuring cap that is grasped by touching the stepped portion on the outer circumference with a finger, it is easier to grasp and the weighing workability by the user can be improved.

The male screw wall portion 24 is provided concentrically with a diameter and has a male screw portion 25 formed on the outer peripheral surface, and extends downward from the lower end portion of the male screw wall portion 24 along the inner peripheral surface of the mouth portion 11. At the same time, it has a bowl-shaped saucer portion 27 having a bottom opening plate 26 that is inclined obliquely. Further, as shown in FIG. 1, when the measuring cap 100, which is provided so as to project upward from the central portion of the saucer portion 27 and has the liquid return cylinder portion 31 inserted and arranged in the liquid recovery recess 21, is attached, the liquid return cylinder portion It has a pouring nozzle 28 arranged inside 31.

The skirt wall portion 22 has an engaging uneven portion 29 on the inner peripheral surface of the lower end portion thereof, and the main body cap 20 is pushed into the mouth portion 11 of the container main body 10, and the engaging uneven portion 29 is used as the base of the mouth portion 11. The main body cap 20 is attached and fixed to the mouth portion 11 of the container main body 10 by engaging with the engaging uneven portion 12 formed on the outer peripheral surface of the end portion. Further, a female screw portion 35 formed on the skirt-shaped annular wall 34 of the measuring cap 100, which will be described later, is screwed into the male screw portion 25 of the male screw wall portion 24, and the male screw wall portion 24 is inside the saucer portion 27 together with the saucer portion 27. A liquid recovery recess 21 is formed in the skirt.

The saucer portion 27 is a bowl-shaped portion that is inserted and arranged inside the mouth portion 11 of the container body 10, and is located at the lowest portion of the diagonally inclined bottom opening plate 26 and has a liquid return opening. 26K is formed. Then, when the measuring cap 100 is reattached, the excess liquid collected from the measuring cap 100 into the liquid recovery recess 21 can be returned to the inside of the container body 10 through the liquid return opening 26K. There is. Further, in the central portion away from the peripheral edge portion of the bottom surface opening plate 26, a pouring nozzle 28 is provided so as to project from the bottom surface opening plate 26 to the upper side of the male screw wall portion 24. The dispensing nozzle 28 has substantially the same shape as the dispensing cylinder described in, for example, Japanese Patent Application Laid-Open No. 2001-139049, and communicates with the outflow opening 26K formed in the bottom opening plate 26 at the base end portion thereof. The liquid detergent can be smoothly poured into the measuring cap 100 through the tip spout 28L whose cross-sectional shape is smaller than that of the spout 31A of the measuring cap 100.

The measuring cap 100 is used by being removed from the mouth portion 11 of the container body 10 when measuring the liquid detergent or pouring the measured liquid detergent into a washing machine or the like. The measuring cap 100 receives the liquid detergent flowing out of the tilted container body 10 from the upward spout 31A at the time of weighing, and is turned upside down at the time of pouring into a washing machine or the like, and the measured liquid detergent is directed downward at the spout. Pour out from 31A.

The measuring cap 100 is composed of two members, a lower member 30 and a canopy member 40, which are vertically divided. For example, the lower member 30 and the canopy member 40 are both formed by injection molding a synthetic resin and have a shape designed so that the mold can be easily pulled out during injection molding. The synthetic resin forming the lower member 30 is preferably transparent or translucent from the viewpoint of visibility of the content liquid poured into the measuring cap 100. The synthetic resin forming the canopy member 40 may be transparent or translucent, but it is preferable that the synthetic resin is not transparent when the light-shielding property of the content liquid is required.

It will be described later that in the measuring cap 100, the lower member 30 and the canopy member 40 can be made of different resin materials.

The lower member 30 is provided with a liquid return cylinder portion 31 having a spout 31A on the lower end side, which is the end portion on the container body side, and has a substantially cylindrical shape, and is connected to the upper end portion of the liquid return cylinder portion 31 to form a cylinder. A liquid storage cylinder portion 32 having a shape is provided. When the measuring cap 100 is attached to the main body cap 20, the spout 31A of the liquid return cylinder portion 31 is inserted and arranged inside the main body cap 20 (in this embodiment, the liquid recovery recess 21 of the main body cap 20) from above. The liquid reservoir cylinder portion 32 extends upward from the outside of the main body cap 20. The lower member 30 forms a liquid return cylinder portion 31 and a liquid reservoir cylinder portion 32 by a single wall.

The canopy member 40 is adhered to and joined to the upper end portion of the liquid storage cylinder portion 32 in the lower member 30, and constitutes a measuring cap. In this embodiment, the measuring cap is fitted and configured. The joining of the lower member 30 of the canopy member 40 to the upper end portion of the liquid reservoir cylinder portion 32 is not limited to fitting, and may be screwed or an adhesive. In the measuring cap 100, the liquid return cylinder portion 31 of the lower member 30, the liquid reservoir cylinder portion 32, and the canopy member 40 form a canopy cylinder-shaped liquid reservoir portion 101, and the canopy member 40 forms the liquid reservoir portion 101 when the liquid reservoir portion 101 is weighed. Become the bottom. The liquid reservoir cylinder portion 32 of the lower member 30 includes an inner diameter D2 larger than the inner diameter D1 of the liquid return cylinder portion 31 (FIGS. 1 and 2).

By forming the measuring cap 100 with two members, the lower member 30 and the canopy member 40 in this way, the liquid return cylinder portion 31 of the lower member 30 is not restricted by the die-cutting property at the time of molding the measuring cap 100. While making it possible to mold the lower member 30 whose diameter is reduced so that the diameter of the spout 31A provided can be inserted into the main body cap 20, the diameter of the liquid reservoir cylinder 32 of the lower member 30 is increased to increase the diameter of the liquid reservoir 101. The weighing cap 100 with an increased capacity can be configured. Therefore, it is possible to secure a large liquid storage capacity in the liquid storage portion 101 of the measuring cap 100 without unnecessarily increasing the diameter of the mouth portion 11 or the main body cap 20 of the container main body 10.

The lower member 30 and the canopy member 40 are joined by fitting the canopy member 40 to the outside of the upper outer peripheral surface of the lower member 30, forming a measuring cap 100. The measuring cap 100 configured in this way has a liquid return cylinder portion 31 of the lower member 30 inserted and arranged in the liquid recovery recess 21 of the main body cap 20 when the measuring cap 100 is attached to the main body cap 20, and the liquid of the lower member 30. The return cylinder portion 31 and the liquid reservoir cylinder portion 32 have a liquid reservoir portion 101 formed together with the canopy member 40.

It is provided with a length arranged near the bottom opening plate 26 of the portion 27. Further, when the measuring cap 100 is screwed and attached to the main body cap 20, the lip 31L formed in an annular shape on the peripheral edge of the opening of the spout 31A has a contact step formed on the inner peripheral surface of the saucer portion 27. It comes into close contact with the portion 27A, thereby preventing the contained liquid detergent from wrapping around in the gap between the liquid return cylinder portion 31 and the liquid recovery recess 21 on the outside, and providing a sealing property. It is improving. The lip 31L of the spout 31A improves the above-mentioned adhesion of the saucer portion 27 to the contact step portion 27A, and also improves the liquid drainage property when the content liquid is poured from the measuring cap 100 to prevent liquid dripping. There is also an effect.

Further, the spout 31A of the liquid return cylinder portion 31 is projected in a straight shape toward the inside of the main body cap 20. As a result, when the female screw portion 35 of the lower member 30 is screwed to the male screw portion 25 of the main body cap 20, when the spout 31A of the liquid return cylinder portion 31 of the lower member 30 begins to be inserted inside the main body cap 20, it is straight. The spout 31A that protrudes in a shape is guided to the inner surface of the main body cap 20, and the measuring cap 100 is coaxial with the central axis of the main body cap 20 to avoid slanting, and the screwing is easy and reliable.
