Description

  The present invention relates to a dripping container that encloses a chemical solution.

  Of the dripping containers in which a small amount of chemical solution is enclosed, those that are used in a small amount in particular are often used for application or administration directly from the dripping container. Many containers that require use with such dripping are usually provided with a nozzle in the container body.

  By the way, the nozzle provided in the container is formed in the upright direction of the container body, and is configured to buffer sudden dripping by once generating droplets at the tip of the nozzle so as to facilitate adjustment of dropping. . For example, a taper is formed such that the cross-sectional area increases as the nozzle lumen moves toward the tip, or the proximal end of the nozzle extends into the container.

However, in either case, in the operation of dripping the chemical solution, in many cases, the dripping container is inverted so that the nozzle is almost directly below, and as a result, a large amount of the chemical solution is dripped unexpectedly. It will occur.
Especially when the surface tension of the chemical solution is low or the viscosity is low, when the chemical solution contains volatile components, when the gas inside the container is slightly expanded during storage, or when the container is inverted at the time of dropping This is likely to occur when the pressure to be discharged to the nozzle tip is easily applied, such as when the level difference from the liquid level inside the container to the nozzle tip is large.

  Therefore, in order to prevent unintentional dripping of chemicals when the container is inverted, the container outlet has a structure in which a certain amount of liquid is discharged each time the container is shaken. A dripping container having a check valve that prevents the outflow of liquid has been proposed. This has a short cylindrical outlet at the upper end, and has a small hole at the upper and lower ends in the above-mentioned outlet of the container main body which has an inclined cylindrical shape whose peripheral surface gradually protrudes outward toward the bottom surface. A ball cylinder, which is provided with an upper and lower valve seat and has several ridges provided vertically on the inner peripheral surface, is preliminarily enclosed and fitted in such a manner that the ball is surrounded by the ridges in a freely rolling manner. (Patent Document 1).

  Moreover, in order to prevent a chemical | medical solution dripping unexpectedly, the dripping container which can administer a chemical | medical solution by inclining without inversion is proposed. For example, as shown in FIG. 2 (b), this is provided with a spout at the top surface end of the container body, and the nozzle is inclined from the spout in a direction away from the container body (dropping direction). It is. Since the nozzle is inclined in the dropping direction, when the container body is inclined, the chemical solution that has reached the spout is dropped through the nozzle.

  In the container described in Patent Document 1, fine adjustment of the amount of dripping liquid is difficult, and when the dripping container is shaped as shown in FIG. In the case of a drug droplet, the drug solution is quickly dropped from the nozzle, and the drug solution is unexpectedly administered without much difference from the behavior of the drug solution when the drug solution bottle is reversed and administered as shown in Patent Document 1. There is a risk that. It is because these administration states have a large level difference from the liquid level of the chemical solution in the dropping container to the tip of the nozzle at the time of administration, and the liquid pressure of the chemical solution in the dropping container is applied downward. This is because the liquid pressure drops. For this reason, the waste of the chemical solution and the dripping of an excessive amount of the chemical solution may cause troublesome treatment. In addition, when tilting the dropping container to drop the medicine droplet, if the chemical solution in the dropping container is dripped from the nozzle before the dropping container is tilted horizontally, it is difficult to control the dropping. There is a risk of dripping. Therefore, it is necessary to avoid the dripping of the chemical liquid and to have a structure with little residual liquid in the container even at the time of disposal.

  An object of the present invention is to provide a dripping container in which a chemical solution is not dripped from the container inadvertently and there is no amount of chemical solution remaining in the container.

Therefore, as a result of intensive studies, the inventors have arrived at the following invention.
A dripping container for administering a chemical solution, a container main body, a spout formed in the center of the top surface of the container main body, and a nozzle extending upward from the spout with an inclination to the upright direction of the container main body And at least the upper inner wall of the container body on the tip side of the nozzle is inclined toward the spout.

  Further, a dripping container for administering a chemical solution, the container body, a spout formed on the top surface of the container body, and the container body so as to tilt from the spout to the center side of the container body. And a nozzle that extends upward while inclining with respect to the upright direction, and at least an upper inner wall of the container body on the tip side of the nozzle is inclined toward the spout.

  It is said dropping container formed integrally with the said nozzle and the said jacket.

  The container body is the above-described dripping container having flexibility and a spherical surface in which a central portion of a side surface located in parallel with the nozzle tilt direction swells outward.

  In the above-described dropping container, the sectional area of the lumen of the nozzle is gradually increased toward the tip.

  In the above-described dripping container, the base end portion of the lumen of the nozzle is water-repellent.

  By using the dripping container, the height difference between the nozzle and the liquid level of the chemical solution in the dropping container at the time of dropping can be made smaller, and the liquid pressure of the chemical solution in the container can be suppressed from being applied to the spout. The chemicals will not dripping from Further, since the upper inner wall of the container body has an inclination toward the spout, the chemical solution in the container is easily led out to the spout. Therefore, even if the content of the chemical solution in the dripping container is reduced, the chemical solution is reliably guided to the spout, so that the chemical solution can be used without waste and there is little remaining chemical solution at the time of disposal. Furthermore, it has been found that by providing a jacket for the container body, it is possible to prevent body temperature from being transmitted from the hand, prevent volume expansion of the substance in the container, and avoid unexpected drug administration. Invented.

  The dripping container of the present invention can be suitably used for medical treatment because it prevents unintentional derivation of the chemical solution and can be used without waste.

  Hereinafter, the dripping container of this invention is demonstrated using figures. However, the present invention is not limited to the exemplary embodiments described in these drawings.

  FIG. 1 is a cross-sectional view and a front view of an embodiment of a dropping container according to the present invention. 2A and 2B are a longitudinal sectional view in a state where the dropping container of FIG. 1 containing a chemical solution is tilted, and FIG. 2B is a longitudinal sectional view in a state where the dropping container at a conventional nozzle position is tilted. FIG. 3 is a front view of another embodiment of the dropping container of the present invention.

  The dropping container of the present invention will be described with reference to FIG. Hereinafter, the nozzle tip side is defined as the front. The bottomed container body 1 has a spout 2 at the center of the top surface, and is formed so as to have an inclined portion 11 inclined toward the spout in front of the upper part of the container body 1. The spout 2 is fitted with a spout fitting portion 31 provided with a nozzle 3 inclined in the direction of the inclined portion 11 with respect to the upright direction of the container main body. A jacket 4 is integrally formed so as to cover 1. Four ribs 41 are formed on the inner wall of the jacket 4 so that the container body 1 is stably accommodated in the jacket 4. A screw thread 32 is formed at the base end of the nozzle 3, and a cap 5 is detachably attached to the nozzle 3 by screwing. The method of attaching and detaching the cap 5 to the nozzle 3 is not limited to screwing, and may be a one-touch type.

  A spout is provided in the center of the top surface of the container body, and a nozzle that is inclined forward from the spout is provided, so that the container body can be reliably passed through the nozzle by simply tilting it toward the tip of the nozzle without being inverted. Can be dripped locally. In addition, since the spout is located at the center of the top surface of the container, the chemical solution in the container main body is dropped at the conventional nozzle position as shown in FIG. Unlike b)), the chemical solution moves to the front of the container body and no liquid pressure is applied to the spout. Therefore, unexpected dripping can be suppressed and a desired amount can be dripped gently.

  The shape of the container main body 1 is not particularly limited as long as it has an inclined portion in front of the upper portion of the container main body toward the spout. Moreover, about the material of the container main body 1, if it does not react with the chemical | medical solution in a container, it will not specifically limit. Examples of the material used include polyethylene and polypropylene.

  The nozzle 3 can further buffer a sudden drop by generating a drop when the tip of the lumen is water-repellent. For example, water repellency can be increased by forming fine irregularities. The material of the nozzle is not particularly limited as long as it has a hardness that does not react with the internal chemical solution and does not deform when pushed. Examples of the material used include polyethylene and polypropylene.

  The jacket 4 may or may not be provided. For example, when the body temperature is transmitted to the container body from the hand holding the container at the time of dripping, the contents in the container body are expanded in volume although the amount is small. Thus, it is preferable that an excessive amount of the chemical solution is prevented from being pushed out from the inside of the container body. The shape of the jacket 4 is not particularly limited as long as it surrounds the container body, and may be integrated with the spout fitting portion as shown in FIG. 1 or may be fixed to the container body. Further, in the container shown in FIG. 1, the jacket 4 is attached by being fitted over the container body, but the means for providing the jacket is not particularly limited. Moreover, although it does not specifically limit about the material of a jacket, It is preferable that there are some thickness and hardness, for example, polyethylene, a polypropylene, etc. are mentioned.

  As shown in FIG. 1, the spout does not have to be provided at the center of the top surface, and it is sufficient that the chemical liquid in the container body does not apply a liquid pressure to the spout when the container is tilted when the liquid droplet is dropped. Therefore, as shown in FIG. 3, the spout may be provided behind the center of the top surface to further secure a space in front of the chemical solution in the container main body when the medicine droplets are underneath.

  As described above, the dripping container of the present invention can be used suitably for medical treatment because it prevents unintentional derivation of the chemical solution and can be used without waste.
