Description

  By reducing the amount of resin used to the limit, the present invention reduces the internal pressure by removing the cap and consuming the contents even a little even if the contents can be self-supported by the internal pressure. It is related with the case with the dispenser for PET bottles shape | molded thinly by which shape-retaining property is lost.

In the case of plastic bottles used for packaging of various beverages and seasonings, the internal pressure decreases when the contents are consumed even a little, so that even if there is a decrease in this internal pressure, it will not deform, so that it can stand on its own. In addition, the thickness is set so that the shape retaining property is not lost even when the inside of the plastic bottle becomes empty.
However, from the viewpoint of conservation of the global environment due to resource saving and disposal, there is a demand for thinning of PET bottles that are consumed in large quantities (reducing the amount of resin used).

Currently, in the case of a shampoo or the like, when a container with a dispenser is first purchased, a product in a soft refill container is purchased, and the product that can be refilled and used is generally used.
For example, in JP-A-2006-219191, as a container that can be used by putting a liquid such as shampoo or rinse in a refillable bag, a removable stopper with a cutter is provided inside the opening of the cylindrical container, There has been proposed a “refillable container for liquids” characterized in that a pump-type lid is provided.
However, this publicly known example is one in which a soft package bag is filled with a pump-type container and is not used for a plastic bottle.

In addition, in Japanese Utility Model Publication No. 5-81051, “a refill container such as a paper pack filled with shampoo or rinse can be attached to a container with a dispenser. More specifically, according to the height of the refill container. As a set structure of a container with a dispenser that allows the contents to be refilled so that the height of the inside of the container with a dispenser can be freely adjusted, a lid with a dispenser attached to the bottomed cylindrical container body `` Separately crowned, refillable container is stored in the container body, the cap is attached to the top surface of the refill container, and the cap and the cap of the dispenser are freely engageable '' Things have been proposed.
However, this known example is not intended for PET bottles, and thus cannot contribute to thinning of PET bottles.

  The purpose of the present invention is to reduce the thickness of plastic bottles to the utmost to save resources and prevent environmental deterioration due to waste. It is to provide a case with a dispenser that can freely consume a fee.

In order to achieve the above object, in the case with a dispenser for thin-walled PET bottles according to claim 1, a dispenser and a PET bottle attachment port are formed in the upper center of the case body in which a bottle housing space for housing the PET bottle is formed. What
The case body dispenser and plastic bottle mounting port, on the outer side is formed with an external screw for screwing and fixing the mounting cap on the dispenser side, and on the inner side is a cap screw formed on the mouth of the plastic bottle. Formed an internal screw that can be screwed in and detachably attached to a plastic bottle,
A dispenser was attached to the outer screw of the attachment port, and a plastic bottle was attached to the inner screw.
It is characterized by.

According to the present invention, the PET bottle with the cap removed is accommodated in the housing space of the case body, and the PET bottle side cap screw is screwed into the inner screw on the case body side by holding and turning the PET bottle by hand. The plastic bottle is accommodated in the case body.
Then, the dispenser-side suction tube is inserted into the PET bottle from above, and the dispenser mounting cap is screwed into the external screw at the top of the case body to attach the dispenser onto the case body.
After that, when the pump head of the dispenser is pushed down, the internal pump is driven, and the contents can be sucked up from the inside of the PET bottle and discharged arbitrarily from the discharge port.

Next, in the invention according to claim 2, the remaining amount of the contents in the plastic bottle can be confirmed by forming a hole in the body portion of the case main body.
According to the present invention, it is possible to save resources and reduce the weight of the case itself.

  Next, in the invention according to claim 3, the front of the case body is opened, and a door is attached to the door so as to be opened and closed, so that the plastic bottle can be taken in and out.

  Next, the invention according to claim 4 is a state in which a cold plastic bottle is kept cold and a warmed plastic bottle is kept warm by attaching a heat insulating material to the inner surface of the body portion of the case body. It is convenient because it can be stored in the case body.

Even if the PET bottle is thinned to the limit, the shape retaining property is maintained in the state where the contents are filled, but if the contents are consumed even a little, the PET bottle will be deformed by decompression. .
However, according to the present invention, since the plastic bottle is attached to the case body at the mouth and accommodated in a suspended state, even if the plastic bottle is deformed, there is no hindrance to suction.
Therefore, the thickness of the PET bottle can be reduced to the utmost to contribute to resource saving and prevention of environmental deterioration, and the manufacturing cost of the PET bottle can be reduced by reducing the thickness.
In addition, in the case of a PET bottle, for example, a bottle containing 2L, it is difficult to handle for elderly people and handicapped people because of its thick body and heavy weight. Since the contents can be poured out, large-sized plastic bottles can be used even by elderly people and people with disabilities.
Moreover, in this invention, since the dimension of the dispenser of a case main body and a plastic bottle attachment port is match | combined with a ready-made thing, a ready-made dispenser and a plastic bottle can be utilized as it is.
