Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to an infusion container containing eye drops and the like.

``Prior Art'' Conventionally, this type of container has generally been used to store liquid for multiple doses because the amount of liquid used per use is small.

``Problem that the invention aims to solve'' For this reason, as the container is used, the cap is removed more frequently, which increases the chances that bacteria will enter the container, and the contents may be damaged by the bacteria entering the container. There were problems such as a decline in the efficacy (quality) of the product.

Therefore, an object of the present invention is to provide an infusion container that is configured in a cartridge type, maintains a sterile state well, and is easy to handle.

"Means for Solving the Problems" In order to achieve the above object, the container of the present invention consists of a non-replaceable member A and a replaceable member B installed in the non-replaceable member, and the non-replaceable member A is A cover cylinder 4 with finger insertion holes 3, 3 formed in the upper portions of the left and right side walls of the cylinder wall 2 with a top wall, and upper ends of both left and right sides of the elastic cylinder part 5 fitted on the inner surface of the middle part of the cylinder wall. The vertical rods 6, 6 are erected from the vertical rods 6, 6, and the outer surfaces of the finger rest plates 7, 7 attached to the upper ends of both vertical rods are formed with the operating member 8 exposed in the above-mentioned through hole, and the above-mentioned replacement member B The lower half of the body 14A is unrotatably fitted into the inner surface of the cylinder wall below the elastic cylinder, and the upper half of the body, which is formed to have a smaller outer diameter than the lower half, is attached to the elastic cylinder. located between the two vertical rods through the inside of the section, with a predetermined gap between them and the inner surfaces of both vertical rods,
and the mouth and neck part 14B from the lower end of the torso to the lower part of the cover cylinder.
It is formed by a liquid storage container body 14 that hangs down, and a cap 15 that is screwed onto the outer surface of the mouth and neck part, and the upper half of the body body of the container body is formed to be elastically compressible. Projections 9, 9 are attached to the inner surface of the lower part of the body, which are capable of squeezing the upper half of the torso by inclining both vertical rods inward through the finger rest plates. It is characterized by

"Operation" For example, if the finger rest plates 7, 7 are pressed inward after removing the cap 15 from the state shown in FIG. The upper half of the container body 14A is squeezed. As a result, the liquid inside the container is pressurized and drips from the container mouth and neck 14B. In this case, since the finger plate is attached with a predetermined leverage ratio with respect to the vertical rod, the operation force is small, and the amount of operation (inward stroke amount) is large, which prevents dripping. The amount can also be easily adjusted.

Furthermore, when the liquid content is exhausted, the container body 14 may be removed from the cover tube 4 by pulling it out through the cap 15, and then a new container body with a cap may be attached to the cover tube.

``Example'' An example of the present invention will be described below based on the accompanying drawings.

In FIGS. 1 and 2, A indicates a non-replaceable member, and B indicates a replaceable member installed in the non-replaceable member A, respectively.

Non-replaceable members A include a cover cylinder 4 made of synthetic resin in which finger insertion holes 3, 3 are bored in the upper portions of both left and right side walls of a circular cylinder wall 2 with a top wall 11, and an inner surface of an intermediate portion of the cylinder wall 2. Vertical rods 6, 6 are erected from the upper ends of both the left and right sides of the circular elastic cylinder portion 5, which is fitted into the circular elastic cylinder portion 5, and arc-shaped finger rest plates 7, attached to the upper ends of both vertical rods 6, 6.
7 and an operating member 8 made of synthetic resin whose outer surface is exposed inside the through holes 3, 3. moreover,
Semicircular protrusions 9, 9 are attached to the lower inner surfaces of both the vertical rods 6, 6. In the illustrated example, the through holes 3, 3 of the cover tube 4 are formed continuously on both the left and right sides of the top wall 1, and correspondingly, the upper ends of the finger rest plates 7, 7 of the operating member 8 are formed in a crescent shape. end plates 10, 10 of
is attached. Further, a plurality of spline grooves 11 are bored in the inner surface of the lower part of the cover cylinder 4 in the circumferential direction.

In the replacement member B, the lower half of the body 14A is unrotatably fitted into the inner surface of the cylinder wall 2 below the elastic cylinder 5, and the body 14 is formed to have a smaller outer diameter than the lower half.
The upper half of A is passed through the elastic cylindrical portion 5 and positioned between the vertical rods 6, 6 with a predetermined gap between them and the inner surfaces of the vertical rods 6, 6, and the body portion 1
It is formed by a small liquid storage container body 14 made of synthetic resin, with a neck part 14B hanging down from the lower end of the cover tube 4A, and a cap 15 screwed onto the outer surface of the mouth neck part 14B. . The container body 14
Inside is a small amount (for several uses) of eye drops and other liquids. In addition, in the illustrated example, the container body 14
is divided into a body member 14A and a mouth and neck member 14B. The body member 14A has the spline groove 11 of the cover cylinder 4 on the outer surface of the lower half formed in a cylindrical shape.
A plurality of spline grooves 16 are formed in the circumferential direction, and the upper half portion is formed into a thin flat cylinder shape in the left-right direction so as to be elastically compressible by thin-wall molding or the like. The mouth and neck member 14B includes engagement means 17 having uneven stripes on the inner surface of the lower half of the body member 14A.
A threaded lower cylinder part 20 is connected to the lower end of the upper cylinder part 18 fitted with a flange part 19. Further, the cap 15 has a protrusion 21 protruding from the inner surface of the top wall that is closely fitted into the lower end opening of the lower cylinder portion 20.

By inclining both the vertical rods 6, 6 inward through the finger rest plates 7, 7, the upper half of the container body body 14A is squeezed by both the protrusions 9, 9. It's getting old.

"Effects of the invention" As explained above, according to the invention, the container body containing a small amount of liquid is configured to be replaceable with respect to the cover tube, etc., thereby eliminating the opportunity for germs to enter the container body. Therefore, it is possible to always use a sterile liquid content. In addition, since the body of the small container body is not squeezed directly but is squeezed using an operating member using a lever, handling becomes extremely easy.
