Squeezable container

Abstract

[Problem] A squeezable container in which contents do not remain in a spout plug. [Solution] A squeezable container is provided with: an outer container (1) for forming the outer appearance of the container, and having a mouth / neck section (1a); and an inner container (2) for discharging the contents filling the interior of the inner container through the spout plug (3) mounted to the mouth / neck section (1a) when the volume of the inner container is reduced by squeezing the body section of the outer container, and positioned on the inside of the outer container (1). During the recovery stage of the body section of the outer container, which accompanies the squeezing, the squeezable container introduces outside air between the outer container and the inner container via an opening formed in the outer container. Therein: the shared space between a mouth / neck section (2a) of the inner container (2) and the spout hole (3c) of the spout plug (3) is provided with a partition (4) for blocking a connection between the mouth / neck section (2a) and the spout hole (3c); the partition (4) is provided with a gate (4c) for discharging the contents; a valve body (5) enabling the discharging of the contents by opening the gate (4c) using the pressure which accompanies squeezing of the body section of the outer container is positioned on the gate (4c); the partition (4) has an opening (6a) that passes through the partition (4); and a suck-back storage chamber (6) is provided for collecting and storing residual contents present in the shared space between the spout hole (3) and the partition (4), during the recovery stage of the body section of the outer container which accompanies the squeezing. The storage chamber (6) is configured from a storage-chamber body (6b) for forming a residual-contents storage cavity (M), and a slider (6c) for moving inside the storage cavity (M) toward and away from the opening (6a).

Description

technical field [0001] The present invention relates to a squeezing (squeezing) container, which is molded by synthetic resin and is composed of a double inner and outer structure. Here, the so-called internal and external double structure includes any of the following containers: a double container, in which an inner container filled with contents is assembled inside an outer container; and a delamination type container, in which the filling The inner layer body with the content is peeled from the inner wall surface of the outer layer body to pour out the content; hereinafter, the inner container is referred to as the inner container, and the outer container is referred to as the outer container. Background technique [0002] A squeeze container reduces the volume of the inner container disposed inside it by pressing the main body of the outer container, thereby pouring out the contents. The squeeze container is accompanied by the pouring out of the contents, and the intern...

Problems solved by technology

[0006] However, in the above-mentioned conventional check valve, when the valve body moves, part of the upper side liquid in contact with the outside air will flow into the lower side liquid, so whether the quality of the contents in the container can be stably maintained until There is still room for improvement in this regard
