Description

  The present invention relates to a chemical solution container that can be used by opening and closing a cap and dropping a chemical solution by one-hand operation.

  An eye drop container used by dripping a chemical solution into an eye includes a container for containing an eye drop and a cap for closing the mouth of the container. The cap is removed to expose the mouth of the container. A form in which the agent is dropped is generally used. However, if the cap is detached from the container and separated, the cap may be dropped and damaged or lost, and it is inconvenient because it requires both hands to open and close the cap.

  Therefore, a combination of a hinge-type cap and a container has been proposed (Patent Document 1). In this case, the cap is connected to the upper part of the side end surface of the container through a hinge, and the cap is rotated by 180 ° or more to open, thereby allowing the dripping nozzle at the mouth of the container to be exposed to the outside and instilling. it can.

In addition, there is also known a device in which a slide type operation unit and a swing type dripping nozzle are incorporated in a cap attached to the upper part of the container (Patent Document 2). The dripping nozzle in the cap communicates with the mouth of the container through a ball valve. By sliding the operation unit along the arcuate top of the cap, the dripping nozzle is placed in a closed position in the sideways direction and in an upward direction. It can be driven to swing to the open position, and the eye drops from the dropping nozzle can be instilled at the open position.

  According to the former of the prior art, since the cap that opens at 180 ° or more is integrally connected to the container via the hinge, it is located near the upper part of the eye when instilled and is obstructive and has an overall shape. However, there was a problem that it was not clunky and not easy to use. In the latter case, the swinging dropping nozzle must be assembled to the mouth of the container via a ball valve, and requires an interlocking mechanism with the sliding operation unit, so that the overall structure is complicated. There was a problem.

  Therefore, in view of the problems of the prior art, the object of the present invention is to reduce the point that the cap becomes obstructive at the use position by combining the guide frame and the up-and-down rotation type cap. Is to provide a chemical container that can be easily assembled.

  In order to achieve the above object, the structure of the present invention comprises a flat container for storing a chemical solution, a guide frame attached to the upper part of the container, and a cap combined with the guide frame so as to be movable up and down. Closed position to close the mouth of the container that protrudes upward, open position to push the mouth up from the closed position, and use position to rotate the mouth from the open position toward the side of the container and drop the drug solution from the mouth The gist is to take

  The cap has left and right leg portions that hang down along the left and right sides of the guide frame, and can be rotated from the open position to the use position around the opposite inward pin shafts at the lower ends of the leg portions. The guide frame has guide grooves for guiding the pin shaft up and down on the left and right side end surfaces, and a stopper for restraining the pin shaft at the open position can be formed in each guide groove.

  The guide frame may include front and rear guide plates that guide the cap from the closed position to the open position, and the cap is elastically engaged with the engagement rib on the outer periphery of the mouth portion at the closed position. A piece may be provided.

  Furthermore, the container, the guide frame, and the cap can form a neat and integral shape at the closed position of the cap.

  According to the configuration of the invention, the guide frame is formed in a downward box shape that matches the shape of the upper part of the container, and is attached so as to be fitted to the upper part of the container so that the mouth of the container protrudes upward. The cap can be assembled to the guide frame so as to be movable up and down with an outer shape adapted to the guide frame. Therefore, even when the container, the guide frame, and the cap are neatly arranged according to the outer shape of the container and used as an eye drop container, a good feeling of use can be easily realized. The cap is pushed up from the closed position to the open position and rotated to the use position, so that the upper part of the mouth of the container can be opened and the whole can be inverted to drop the medicine from the mouth. This is because the apparent size of the soup is small and it is rare to feel excessive intimidation. The rotation angle of the cap from the open position to the use position is preferably set to at least 120 ° or more, preferably 135 ° or more. In addition, the mouth portion of the container may be provided with a dropping nozzle, and the mouth portion itself may have a shape suitable for dropping a chemical solution.

  The container is elastically deformed by pressing the flat front and rear side surfaces with fingers, and the inner chemical solution is discharged, and the guide frame is integrally formed with an appropriate chemical-resistant elastic material such as polyethylene terephthalate. The cap is integrally formed of thermoplastic high-density polyethylene, polypropylene, or the like. Moreover, it is preferable that a container has transparency or translucency so that the quantity of a chemical | medical solution can be seen from the outside, and a guide frame and a cap may be opaque. Furthermore, the container, the guide frame, and the cap may be arranged in the same color system or in different colors.

  The cap having the left and right leg portions can be assembled to the guide frame so as to be movable up and down so that the guide frame is sandwiched between the both leg portions. The cap can be rotated from the open position to the use position by rotating toward the one of the front and rear side surfaces of the container with the pin shaft at the lower end of the left and right legs as the rotation center. The stopper formed in the guide groove of the guide frame can smoothly rotate the cap from the open position to the use position by restraining the pin shaft of the cap at the open position. The front and rear guide plates provided in the guide frame guide the cap up and down from the closed position to the open position, and prevent the cap from inadvertently tilting and rotating in the meantime during this time. The engagement piece of the cap elastically engages with the engagement rib of the mouth portion in the closed position, thereby holding the cap in the closed position and preventing liquid leakage from the mouth portion of the container.

  The container, the guide frame, and the cap can be conveniently carried in a pocket or a bag by forming a neat and integral shape as a whole with the cap closed. However, “neat” here means that there is no extreme protrusion except for a gap appearing at the joint of the container, guide frame, cap, etc., and it is an integral surface form as a whole. Say.

  The cap 30 in the open position ascends entirely above the guide plates 27 and 27 of the guide frame 20 except for the lower half of the leg portions 31 and 31 (FIGS. 5A and 5B). The shafts 31a and 31a can be rotated back and forth around the rotation center. Therefore, when the cap 30 is tilted forward or backward (in the direction of the arrow in FIG. 10C) and rotated toward one of the front and back sides of the container 10 (in the direction of the arrow in FIG. 10D), the cap 30 is The upper part of the mouth part 12 with the dripping nozzle 13 of the container 10 can be opened to the use position. Accordingly, the container 10 and the cap 30 are sandwiched between the thumb and forefinger and the whole is inverted and held on the eyes (FIG. 6A), and the eye drop in the container 10 is dropped from the nozzle hole 13a of the dropping nozzle 13. Just drop it in. At this time, the container 10 is elastically deformed by applying a pressing force by the thumb and index finger.

  The rotation center of the cap 30 from the open position to the use position is pin shafts 31a and 31a that are restrained by the upper ends of the guide grooves 25 and 25 via stoppers 25a and 25a. Further, the rotation angle of the cap 30 at this time is determined by the cap 30 coming into contact with one side surface of the body portion 11 of the container 10 (FIG. 5D). By setting the rotation angle of the cap 30 to at least 120 ° or more, preferably 135 ° or more, the apparent size of the cap 30 at the time of instillation can be made sufficiently small.

  After instillation, the cap 30 is returned from the use position to the open position (in the direction of the arrow in FIG. 6B), and further pushed into the container 10 side to return to the original closed position to close the mouth portion 12 (FIG. 6C). Arrow direction). When returning from the open position to the closed position, the pin shafts 31a and 31a of the cap 30 can be detached from the stoppers 25a and 25a with an appropriate click feeling, and the restraint by the stoppers 25a and 25a can be released. In the closed position of the cap 30, the container 10, the guide frame 20, and the cap 30 form a neat and integral shape as a whole (FIG. 6C) and can be conveniently carried without causing harmful liquid leakage. it can.

  In the above description, the mouth portion 12 of the container 10 may be deformed into a shape suitable for dripping the chemical solution instead of mounting the separate dripping nozzle 13. In addition, the overall shape when the cap 30 is in the closed position is easy to use, and can be modified into any form other than that shown in the drawings as long as it is small and thin and neat. For example, the bottom of the container 10 can be smoothly bulged downward, and the upper portion of the cap 30 can be smoothly bulged upward so that the container 10 can be formed into a smooth flat oval shape as a whole. At this time, the left and right end faces of the container 10, the guide frame 20, and the legs 31, 31 can be rounded into a circular arc shape.

  The liquid medicine in the container 10 is not limited to eye drops, but may be any liquid medicine used by dropping, such as a contact lens mounting liquid or a diluted mouthwash.
