[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cap attached to a squeeze type container that discharges a content liquid by pressing the container body.

[0002]

[Prior Art]

 Conventionally, as a squeeze type container that presses the container body to discharge the content liquid, for example, as shown in Japanese Utility Model Application Laid-Open No. 49-131256, a measuring container is attached to the mouth of a container body made of a soft resin. It is composed by arranging a tube that connects this measuring container and the container main body.When using, press the container main body and pass the tube to store the necessary amount of contents in the measuring container. It is to pour from. A container has been proposed that can return the excess amount accumulated in the measuring container to the inside of the container body by a siphon phenomenon.

Further, in Japanese Utility Model Laid-Open No. 323066/1990, a cap body and a container body, which are configured to allow the inside of the measuring chamber to be seen through, are communicated with each other by using a suction pipe, and an extracting port is provided in the measuring chamber. With a cap fitted to this extraction port, it was possible to perform suction operation while confirming the amount of liquid in the measuring chamber from the outside, and it was possible to extract even a small amount.

[0004]

[Problems to be solved by the device]

 However, even in the case of each of the above-mentioned containers, it is impossible for the former to completely return the excess content liquid in the measuring container to the inside of the container body in the case of actual use, and it will remain in the measuring container and be treated. There was a problem that I was in trouble. Further, in the latter case, it is necessary to push up the cap with a fingertip when opening the cap, and it is not possible to perform it by one operation.

Therefore, an object of the present invention is to simply open the lid body by squeezing the container body, and to perform a series of operations such as opening the lid body, measuring and pouring the content liquid once. It is to provide a convenient cap that can be operated.

[0006]

[Means for Solving the Problems]

 The above-mentioned object of the present invention is a cap attached to the mouth of a flexible container body, the cap body, a measuring chamber configured in the cap body, and a container in the measuring chamber. A cap comprising: a liquid-conducting mechanism for guiding the content liquid of the main body; an opening formed in the measuring chamber; and a lid body having a closing force for closing the opening of 50 to 500 g. Achieved by

It is desirable that the lid portion has an arcuate vertical cross section, and further, an air replacement hole that connects the measuring chamber and the container body is provided, and the cap body portion and the lid body portion are provided. More preferably, and are connected via a hinge mechanism.

[0008]

[Action]

 As described above, the closing force of the lid body that fits into the opening of the measuring chamber provided in the cap body is set to be 50 to 500 g weight, and the lid body is configured to have an arcuate cross section. Therefore, the air pressurized by the squeeze of the container body acts to spread the end of the lid part evenly over the entire circumference through the liquid guiding mechanism and the measuring chamber, and at the same time the entire inner surface of the lid part is covered. It acts to push it up across and open the lid. At the same time, the squeeze allows the content liquid to flow into the measuring chamber via the liquid guiding mechanism while being metered, so that a series of operations can be performed in one operation, which improves usability.

Further, when the air replacement hole that connects the measuring chamber and the container body is provided, the air for opening the lid portion first passes through the air replacement hole without passing through the liquid guiding mechanism. After opening the lid part, the content liquid flows into the measuring chamber through the liquid transfer mechanism, so the excess content liquid does not scatter with the opening of the lid part, greatly improving usability. .

【Example】

 1 and 2 show an embodiment of the cap according to the present invention. FIG. 1 is a longitudinal sectional view of the cap mounted on a container, and FIG. 2 is a cap fit inside the broken line of FIG. It is the elements on larger scale of a joint part. A is a cap body integrally formed of a transparent or translucent resin material (for example, low-density polyethylene or polypropylene), and a mouth of a container B filled with a liquid content liquid L such as shampoo or emulsion. It is used by being screwed to the section C.

Reference numeral 1 denotes a cylindrical base portion in which a screw portion screwed into the mouth portion C is formed inside. 2 is a measuring chamber that is molded from a transparent or semi-transparent resin material so that the amount of liquid stored inside can be confirmed. The base 1 is composed of a peripheral wall 2a that is continuous and has a reduced diameter and stands upright, and a top plate 2b that covers the upper portion of the peripheral wall 2a. The peripheral wall 2a is engraved with a measuring scale 2c which serves as a guide for storing a fixed amount of the content liquid L in the measuring chamber 2.

Reference numeral 3 is a spout provided in a ring shape on the front portion of the top plate 2 b of the measuring chamber 2. Reference numeral 4 denotes a cap which is connected to the rear end corner of the measuring chamber 2 by a hinge mechanism 2d and which is configured to cover the top plate 2b and the spout 3 of the measuring chamber 2 and has a vertical cross section as shown in FIG. It is formed in a predetermined arc shape. A convex strip 4a is formed on the inner peripheral surface of the end of the cap 4, and is configured to fit with a concave strip 2e formed on the peripheral surface of the upper end corner portion of the measuring chamber 2. The fitting force (closing force) of the cap 4 is set to be 50 to 500 g weight. The fitting force (closing force) can be arbitrarily set (adjusted) by adding a kneading lubricant to the resin material forming the ridges 4a and the ridges 2e.

Reference numeral 5 denotes a liquid guiding mechanism that guides the content liquid in the container B into the measuring chamber 2. The liquid transfer mechanism 5 is molded separately from the cap body A, and is watertight at the boundary between the base 1 and the peripheral wall 2a (the portion located at the same height as the upper surface of the base 1) in the cap body A. Be fitted. The bottom plate 5a which constitutes the bottom surface of the measuring chamber 2 in the fitted state and the nozzle 5b which vertically penetrates the central portion of the bottom plate 5a. A discharge port 5c is provided at the tip of the nozzle 5b that faces the measuring chamber 2, and a dip tube 5d is connected to the opening that faces the inside of the base 1. From the dip tube 5d, the content liquid L of the container B is discharged from the nozzle 5b. And, it is configured to be sucked up and stored in the measuring chamber 2 through the discharge port 5c. 5e is an air displacement hole provided in the bottom plate 5a. The content liquid L stored in the measuring chamber 2 has a predetermined viscosity and surface tension, and in addition, the air replacement hole 5e only needs to be able to replace air, and thus a predetermined size is sufficient. It does not fall into the container B from the air replacement hole 5e in a short period of time, which does not hinder the operation in practical use.

Since the content liquid L exceeding the height of the discharge port 5c returns from the discharge port 5c into the container B, the height of the discharge port 5c can be arbitrarily changed and stored in the measuring chamber 2. It is also possible to set the amount as much as possible. As described above, the ridge 4a formed at the end of the cap 4 and the groove 2e formed at the corner of the measuring chamber 2 have a closing force (fitting force) of 50 to 500 g. Therefore, when the container B is squeezed, the pressurized air passes through the air displacement hole 5e, the measuring chamber 2 and the pouring port 3 and uniformly spreads the vicinity of the ridge 4a of the cap 4, and at the same time, the entire inner surface of the cap 4 is pushed. And the cap 4 is opened. Subsequently, when the container B is squeezed with an appropriate pressing force, the content liquid L flows into the measuring chamber 2 by the liquid guiding mechanism 5, a predetermined amount is measured by the measuring scale 2c, and then it is poured from the pouring port 3. Become.

As described above, a series of operations such as opening the cap 4, measuring and pouring the content liquid L can be performed by only one operation of squeezing the container B, so that the usability is greatly improved. Furthermore, since the air replacement hole 5e is opened in the bottom plate 5a, the pressurized air does not pass through the liquid guiding mechanism 5 and the cap 4 is opened through the air replacement hole 5e by the first squeeze. L flows into the measuring chamber 2 through the liquid guiding mechanism 5. Therefore, the content liquid L that has passed through the liquid guiding mechanism 5 is prevented from being overwhelmed with the air and scattered to the outside when the cap 4 is opened, and the usability is greatly improved.

【effect】

 The cap according to the present invention comprises a cap body, a measuring chamber formed in the cap body, a liquid guiding mechanism for guiding the content liquid of the container body into the measuring chamber, and an opening formed in the measuring chamber. And a lid body having a closing force of 50 to 500 g to close the opening, the air pressurized by the squeeze of the container body completely surrounds the end portion of the lid body having an arcuate cross section. The cover body portion is easily opened by spreading and evenly spreading it over and over the entire inner surface of the lid body portion. Then, by the subsequent squeeze, the content liquid is flown into the measuring chamber by the liquid guiding mechanism while being metered, so that a series of operations can be performed in one operation, and the usability is improved. Furthermore, in the case where an air replacement hole that connects the measuring chamber and the container body is provided, the air for opening the lid does not first pass through the liquid guiding mechanism, but first passes through the air replacement hole and the lid opens. After the part is opened, the content liquid flows into the measuring chamber through the liquid transfer mechanism, so the excess content liquid does not scatter to the outside when the lid is opened, and the usability is greatly improved.
