Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an enema container in which a chemical liquid is not inadvertently leaked from the tip of a nozzle when the nozzle is opened.

[0002]

2. Description of the Related Art An enema drug solution is contained in an enema container with a dedicated nozzle.

In an enema container, the tip of a nozzle is hermetically sealed in order to prevent deterioration or leakage of the drug solution. Therefore, in this device, the tip of the nozzle is opened using, for example, an attached dedicated opening tool, and the opened nozzle is inserted into the anus to inject the drug solution. The enema container may have a bellows at the base of the nozzle in order to use the nozzle at an arbitrary inclination.

[0004]

According to the conventional technique, when an excessive force is applied to open the tip of the sealed nozzle, the internal pressure is increased and the enema container is opened from the nozzle immediately after opening. There is a problem that a chemical solution is often ejected and leaks to the outside. This is because the elastically deformable enema container presses and deforms itself and injects the liquid medicine inside into the anus. In the case of an enema container with a bellows, it is more difficult to open the nozzle without failure because the nozzle is easily inclined.

In view of the above-mentioned problems in the prior art, it is an object of the present invention to seal the nozzle via a screw-type cap and provide a finger-holding surface on the bellows, so that even if the bellows is provided, the bellows can be externally provided. An object of the present invention is to provide an enema container that can easily open the tip of a nozzle without leaking a drug solution.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a container body in which a nozzle is integrally formed on an elastically deformable main body via a bellows, and a screw cap mounted on the nozzle. And the bellows,
The gist of the present invention is to form a finger resting surface by cutting off the top of each step symmetrically.

[0007] The finger-holding surface can be smoothly recessed toward the axis of the bellows, and the bellows increases in order from the upper stage to the lower stage. it can.

The main body and the bellows may be formed in an oval cross section in which the major axis direction and the minor axis direction are the same.

The container body can form a smooth continuous portion from the upper end of the bellows to the male screw portion at the base of the nozzle, and a flare portion covering the continuous portion can be formed at the lower end of the cap. Can be.

[0010]

According to the structure of the invention, since the nozzle is sealed with the screw-type cap, the nozzle can be opened very easily by twisting and removing the cap. The main body can be stably held by sandwiching the finger-holding surface formed on the bellows between fingers. The finger-holding surface is formed by notching the top of each step of the bellows symmetrically in the front-rear direction. In addition, there is no possibility that the chemical solution in the main body unit may leak to the outside carelessly.

In order to ensure a sufficient insertion length of the nozzle, a male screw portion is formed at the base on the bellows side, and the cap covers the entire length of the nozzle.
A female screw part that fits the male screw part on the nozzle side is formed at the lower part of the inner surface. Further, it is preferable to form a knurl for preventing slipping on the upper part of the cap. further,
The male screw part on the nozzle side and the female screw part on the cap side are multi-leaded screws with large leads, respectively.
By making two rotations, it is preferable that the plug on the top surface of the cap can be pulled out and inserted into the nozzle hole at the tip of the nozzle, and the cap can be detached.

The finger-holding surface is smoothly recessed toward the axis of the bellows, so that the finger-holding surface can easily adhere completely to the belly of the finger, and the container body can be held more stably.

[0013] In addition, by making the maximum depth of each of the bellows, which are sequentially increased from the upper stage to the lower stage, uniform, the finger hanging surface can be made longer in the circumferential direction of the bellows from the upper stage to the lower stage. When the container main body is held between fingers, the weight of the chemical solution accommodated in the main body can be easily supported without applying great force to the fingers.

The main body and the bellows have the same long-axis direction and short-axis direction, so that the overall shape is well-formed and the positions of the front and rear finger-holding surfaces can be identified at a glance from the overall shape of the main body. can do.

The container body can easily absorb the difference in shape and size between the bellows and the nozzles through the smooth continuous portion. The bellows is preferably formed in a large size, e.g., oval in cross section, to fit the body, but the nozzle is shaped into a small diameter cylinder, to be inserted into the anus and fit in a threaded cap. It is inevitable.

The cap forming a flare portion at the lower end covers the entire length from the continuous portion to the tip of the nozzle, and can effectively prevent these portions from being soiled before use. The flare portion may cover the entire continuous portion, or may cover only the upper half of the continuous portion.
