Description

  The present invention relates to a container product in which a liquid content such as a liquid detergent or a softener is contained in a main body container, and an inner lid is attached to an upper mouth portion of the main body container filled with the liquid content, A tubular pouring tube having a hollow passage that rises from the bottom of the reservoir and extends upward and communicates the inside of the main body container to the outside, and a container-like bulging portion for measuring liquid contents is formed. The present invention also relates to a container lid having an upper lid that covers the inner lid from above and is attached to the inner lid.

  Some container products containing liquid contents require the use of a predetermined amount, such as a liquid detergent for clothes and a softener, with respect to the water in the washing tub.

  The lid of the container used for this type of liquid content is an inner lid with a dispensing cylinder attached to the main body container filled with the liquid content, and a meter attached to cover the inner lid. It consists of an upper lid with a function.

  To dispense liquid contents, first remove the upper lid, pour a certain amount of contents into the upper lid from the dispensing cylinder while tilting the main body container, and use the liquid contents weighed in the upper lid in the washing tub etc. It is intended to be used.

  However, in the case of a weighing container product that tilts the main body container and pours it into the top lid, in addition to feeling the main body container held heavy during the full-pour operation, the operability is poor for a small amount of measurement, and during measurement, There were problems such as dripping.

  On the other hand, in Japanese Patent Publication No. 4-7094 (Patent Document 1), a cup is attached to a cylinder at the container mouth, and a rigid cylindrical nozzle having a tubular shape and a flange at the lower end is attached to the cylinder. When the cup is used, the through hole and the periphery of the nozzle are closed by the flange. Then, when the cup is screwed onto the cylindrical body after the cup is weighed, the inner bottom of the cup hits the tip of the nozzle, and the nozzle is pushed down to open a gap between the through hole and the nozzle so that the residual liquid returns to the cup through the gap. It is a thing.

  On the other hand, as a technique for measuring a small amount of liquid content, a structure in which the container is pressed to increase the internal pressure and the liquid content is extracted from a thin pouring tube (pouring nozzle) can be considered. There was a problem that if the contents were taken out too much, they could not be returned to the container.

In this case, a high-rigidity nozzle pushed down by the cup as in the above-mentioned Patent Document 1 cannot be used for the dispensing cylinder. That is, if the liquid measuring cap of Patent Document 1 is formed with a thin and low-rigidity nozzle (pouring cylinder), the nozzle may be bent or damaged due to repeated use, and repair such as nozzle replacement may be performed. Due to the necessity, it has a problem that it is not practical and the cost is increased.
