[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a bottle, a method for producing the same, and a mascara container using the bottle, and more specifically, a synthetic resin bottle that can reliably prevent the attached member fitted to the inner surface of the mouth and neck from coming out. The present invention relates to a manufacturing method and a mascara container in which a handling member is securely fitted to the mouth and neck using the bottle.
[0002]
[Prior art]
As a synthetic resin bottle, a bottle formed by blow molding and having a mouth and neck raised from a trunk through a shoulder is known. These bottles have a variety of uses. In addition to the very general usage in which a cap is detachably fitted to the mouth and neck, the bottle is used by fitting an accessory member in the mouth and neck as well as the cap. There are many cases.
[0003]
For example, like a mascara container, makeup brushes and makeup brushes are attached through a shaft attached to a cap and suspended in the container body, and the mouth and the excess adhering liquid on these brushes are scraped off. There is a type in which a handling member provided with a protruding projecting shape that tapers inwardly in the neck is fitted.
[0004]
[Problems to be solved by the invention]
In the conventional bottle of this type, the inner surface of the mouth and neck portion is formed smoothly. Therefore, when these attachment members such as the handling members are fitted, the sliding force is prevented by the frictional force between the contact surfaces. The effect is still insufficient. In particular, when the attachment member is a handling member or the like, since the force is applied in the pull-out direction every time the cap is removed, the attachment member is easily removed.
[0005]
In consideration of these points, a protrusion is formed on the lower part of the outer surface of the fitting tube of the accessory member, and the fitting tube is forcibly fitted into the mouth and neck to engage the protrusion with the lower surface of the mouth and neck. Thus, there has been proposed a structure configured to prevent slipping out. Although these have a certain effect, the one with such a large projection width is impossible in order to forcibly fit the projection, and as a result, the area of the engagement portion is small and it is still not possible to prevent the projection from coming out. There are enough places.
[0006]
The present invention has been made in view of the above-described points, and can securely fix the attached accessory member, does not cause inconvenience such as coming out during use, and exhibits these effects with a simple structure. It proposes a bottle made of synthetic resin that can be made.
[0007]
In addition, the present invention proposes a manufacturing method capable of manufacturing the above-described bottle simply, inexpensively, and with a sharp groove.
[0008]
Furthermore, the present invention proposes a mascara container that uses the above-described bottle and does not cause inconvenience such as the handling member coming out.
