Abstract

PURPOSE: To smoothly drip a content by a method wherein a presser element is supported on a bottom frame at two or more positions around the circumference and allowed to move along the length of a main body to press a diaphragm vertically. CONSTITUTION: When a user removes a cap 8 and presses a presser element 6 with a finger with a nozzle 2a down, the presser element 6 moves toward a container main body 2 against the force of elastic connecters 7 so that a central part 3a of a diaphragm plate 3 collapses inward, causing the inside space of the container main body 2 to be forced to shrink. Therefore, a pressure working on a content causes the content to spout and drip from the nozzle 2a. As the periphery of the presser element 6 is uniformly supported by the three elastic connecters 7 at equal intervals, the presser element 6 moves in the direction perpendicular to the diaphragm plate 3 even if the presser element 6 is pressed at a part off the center. In addition, when the presser element 6 is pressed with the user's finger, a bottom frame 5 restrains the pressing direction of the user's finger and helps the presser element 6 move in the right direction.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a container in which the contents can be poured out from a nozzle by pushing a diaphragm plate at the bottom, and is particularly suitable for containing eye drops and a cleaning solution for contact lenses. Regarding the container.

[0002]

2. Description of the Related Art Conventionally, as a container of this type, a container disclosed in Japanese Utility Model Publication No. 4-43500 developed by the applicant of the present patent application has been known. This container has a nozzle at the head of the container body and a diaphragm plate at the bottom thereof, and an annular bottom frame is attached to the peripheral edge of the diaphragm plate. An exterior bottom plate, which is a pressing piece, is arranged in the central space of the annular bottom frame so as to overlap the diaphragm plate, and the exterior bottom plate and the annular bottom frame are connected by one elastic connecting portion. .

That is, the outer bottom plate is movable around the elastic connecting portion as a fulcrum, and when the user of the container pushes the outer bottom plate, the diaphragm plate is distorted toward the inner side of the container body to reduce the inner space, and the contents are discharged from the nozzle. The structure is such that it is extruded and poured out.

[0004]

However, according to the above structure, the outer bottom plate has a movable structure with a single elastic connecting portion as a fulcrum, so that a user who is not familiar with the use of the container presses the vicinity of the elastic connecting portion. If this happens, the exterior bottom plate will not move smoothly and the contents cannot be poured out from the container.

Further, since the locus of movement of the outer bottom plate is a turning locus with the elastic connecting portion as a fulcrum, the force applied perpendicularly to the outer bottom plate is also applied as a bending force to the diaphragm plate, and the diaphragm plate is smoothly moved. There was also a problem that it could not be pressed. Further, in the conventional structure, the stroke and the pressing resistance of the exterior bottom plate are mainly borne by the shape and elasticity of the diaphragm plate, and this cannot be adjusted by the elastic connecting portion, and it is not possible to set the dropping amount of the contents, for example. It was possible.

Therefore, an object of the present invention is that even a person who is unfamiliar with the use of the present invention can smoothly drop the contents, and the force applied to the pressing piece can be transmitted vertically to the diaphragm plate. Another object of the present invention is to provide a drip-type pour-out container in which the stroke and pressure resistance of the pressing piece can be set to adjust the drip amount of the contents and the like.

[0007]

According to the present invention, there is provided a container body having a pouring nozzle formed in a head portion and an opening portion formed in a bottom portion, and a film body having flexibility in at least a central portion,
A diaphragm plate that is attached to the container body so as to close the opening, presses the contents of the container by being pressed, and drops the contents from the pouring nozzle, a bottom frame that is attached to the bottom of the container body, and A bottom member having a pressing piece that is supported at a plurality of locations around the bottom frame and that moves in the length direction of the container body and that can press the diaphragm plate in the vertical direction, and , Solves the above problems.

Further, the pressing piece is supported by the bottom frame via a plurality of elastic connecting portions arranged around the pressing frame, and the pressing piece, the bottom plate and the elastic connecting portion are integrally formed of a resin material having elasticity. It is even better to use a dispensing container.

[0009]

When the user presses the pressing piece, the diaphragm plate is dented inside the container, the space of the container is compressed and the contents are poured out from the nozzle and dropped. Since the pressing piece is elastically supported at a plurality of locations around the pressing piece, the pressing piece moves smoothly regardless of which part of the pressing piece is pressed. Further, for this reason, the pressing piece moves in the length direction of the container body and can press the diaphragm plate in the vertical direction.

Further, by connecting the pressing piece with a plurality of elastic connecting portions, the stroke and pressing resistance of the pressing piece can be set, and various settings can be made according to the contents.
