Then, the medicine applying device a opens the opening means d of the container body b when necessary (see FIG. 8 (2)), and applies the medicine or the like, for example, a disinfectant solution directly to the affected area by the exposed columnar applying member c. It is configured to be capable (see FIG. 8 (3)).

However, the above-mentioned drug applying device a is convenient when the drug or the like is a liquid, but is not suitable for a creamy one. Therefore, there is JP-A-61-288870 as a drug application device that can be used favorably even with a creamy drug or the like.

[Problems to be Solved by the Invention] The above-mentioned drug application device (Japanese Patent Laid-Open No. 61-288870) is capable of applying cream-like highly viscous drugs and the like to the affected area in good condition. However, on the contrary, it is unsuitable for liquid chemicals, etc., and since the insertion member exposed to the outside is inserted into the container body as it is and the chemicals etc. are pressed and discharged from the medicine ejection hole, it is likely to become unsanitary. . Furthermore,
Since the insertion member itself is used as a plunger,
If the outer peripheral surface of the insertion member and the inner peripheral surface of the container body are not precisely processed, the drug or the like will be ejected to the insertion side, and these processes are not easy.

Therefore, the present invention has been made in view of the above circumstances,
It is an object of the present invention to provide a drug application device that is hygienic, easy to process, and can be used for any drug such as cream and liquid.

The side opening is on the ejection side of the drug 5 and the like, and the drug applying member 9 is fixed in the inclined cylindrical portion 6a.

This container body 6 is formed so as to be able to compress at least a volume corresponding to the volume of the drug etc. 5 contained therein. The container body 6 may have any form of compressive deformability, and in the present embodiment, the container body 6 is compressed.
It is made of a relatively soft material to the extent that the above volume can be compressed by pressing itself with fingers. Further, the compressive deformability of the container body may be capable of compressing the above-mentioned volume due to its own structure. For example, a bellows is provided in a part of the container body 6,
The volume may be compressed by deforming the bellows.

Further, the container body 6 has the other end closing portion (the other end closing side) 10 thereof.
It may be made of a relatively soft material capable of compressing the above-mentioned volume by pressing only the finger with fingers, and other parts of the container body may be made of a hard plastic material or the like.

Since the drug applying member 9 applies the drug 5 or the like to the affected area, it is preferable that the application surface is sufficiently smooth so as not to damage the affected area. Since the drug applying member 9 is sealed inside the first member 2 of the pre-use drug applying device 1, it is possible to maintain sterility.

On the other hand, the medicine applying device 1 is provided with a horizontal cylindrical portion b
The pressure transmitting member 7 may be housed inside, and the medicine or the like 5 may be pressed in response to the compression of the container body 6 to eject the medicine or the like 5 from the ejection hole 8. The pressure transmitting member 7 is for ejecting the medicine or the like 5 in the first member 2 from the ejection hole 8 of the medicine applying member 9. The pressure transmitting member 7 has a bag-like outer shape, and air is contained therein. As described above, the horizontal cylinder portion 6b of the container body 6 is pressed with fingers to compress the medicine 5 or the like. While abutting against the end surface of the medicine 5 etc., the medicine 5 etc. can be completely discharged. Also,
This pressure transmitting member 7 is provided when the horizontal tubular portion 6b is compressed.
The medicine or the like 5 should be in close contact with the closed side of the horizontal tubular portion 6b to such an extent that it does not leak.

Further, if the pressure transmitting member 7 receives the compressive force due to the pressure applied to the container body 6 and transmits it to the drug 5 or the like in the container body 6 to discharge the drug 5 or the like from the discharge hole 8,
It may be of any type, for example, a bag filled with a liquid such as water or a bag having a bellows.

The pressure transmitting member 7 may be configured so that it can move without deforming itself and press the medicine 5 or the like.

As shown in FIG. 2, the medicine or the like 5 is housed in the hollow portions of the inclined tubular portion 6a and the horizontal tubular portion 6b of the container body 6. As the drug 5 or the like, a highly viscous one such as ointment, cream or gel is used. Further, a material having an impregnating property, for example, a foam material impregnated with a liquid drug 5 or the like may be used.

The unsealing means 3 is a portion of the peripheral wall having a reduced thickness, 0.05 to
The thickness is set to 0.5 mm, preferably 0.1 to 0.2 mm. The unsealing means 3 has, for example, a V-shaped groove as shown in FIG. 2, and the radius of curvature of the groove bottom is as small as possible. It is important to set the opening means 3 so that the stress on the groove bottom is concentrated and is easily broken only when a force in the bending direction is applied from the lateral direction to the drug application device 1 so that the force is not usually applied. Then, the medicine applying device 1 is opened by grasping both sides of the opening means 3 with both hands and applying the thumbs of both hands to both sides of the opening means 3 and applying a force in the bending direction to break the opening means 3. It As a result, the medicine applying device 1 is separated into the first member 2 and the second member 4 as shown in FIG.

The second member 4 includes a small diameter portion 4a and a large diameter portion 4b. The small-diameter portion 4a has a partition wall and is formed so as to ensure the sterility of the drug 5 and the drug applying member 9.

The large diameter portion 4b of the second member 4 is preferably formed in a shape that can be attached to and detached from both ends of the container body 6. The large diameter portion 4 is provided on the discharge side of the drug 5 of the container body 6.
If b is attached or detached, the second member 4 can be used as a cap. In addition, the large diameter portion 4b is provided on the other end closing portion 10 side of the container body 6.
If the second member 4 increases the total length in the longitudinal direction, the medicine 5 or the like can be applied to a range that is difficult for the fingers to reach.

The material of the container body 6 and the second member 4 is made of a plastic material which is inert to the drug 5 and has low permeability. It is desirable that this plastic material is composed of a plastic material of the same series as the inclination of the container body 6 and the horizontal cylindrical portions 6a and 6b and is made of a hard material in order to perform ultrasonic fusion. Therefore, as a preferred example, the plastic material, polypropylene, polystyrene, polycarbonate, polyethylene terephthalate, using polymethylpentene, etc., by injection molding, extrusion molding, blow molding, injection blow molding and vacuum molding,
Each part is molded individually.

When the container body 6 and the second member 4 are firmly joined and sealed as a whole with the medicine 5 or the like contained in the hollow portion of the container body 6, if the plastic materials used are of the same series, Ultrasonic welding is possible, and strong bonding is possible.

The material of the pressure transmitting member 7 is preferably the same as that of the container body 6 and the second member 4, and is preferably inert to the drug 5 and has a good shape change property.

The material of the drug applying member 9 is preferably the same as that of the container body 6 and the second member 4, and it is inert to the drug 5 and has a good shape-retaining property, and feels when applied to the skin or the like. It is preferable to use a foamed material such as polypropylene, polyethylene, polyurethane, polystyrene, silicone, polyethylene-vinyl acetate copolymer and polyvinyl chloride, which is easy to apply and does not easily cause the coated member pieces to come out.

In the method of assembling the drug applying device 1 of the present invention, first, the pressure transmitting member 7 is housed and fixed in the container body 6 from the opening of the inclined cylinder portion 6a, and the drug 5 is further housed, and then the drug applying member 9 is installed. Insert and fix in the compressed state. Then, the second member 4 is ultrasonically adhered to the opening of the container body 6 on the side of the inclined cylinder portion 6a in the state where the above-mentioned V-shaped groove, that is, the unsealing means 3 is present.

Next, the operation of the drug application device 1 having the above-described configuration will be described. First, the drug application device 1 containing the required drug 5 is selected. The container body 6 of the drug applying device 1
The first member 4 and the first member 4 are respectively made of plastic, and the unsealing means 3 acts for unsealing the drug applying device 1. Usually, this opening is performed by grasping the container body 6 and the second member 4 in the first member 2 with both hands and applying the fingers of both hands to both sides of the opening means 3 to open the drug application device 1. Bending at the position of the means 3, that is, applying a force to each finger in the direction of arrow A in FIG. 3, tearing the thin peripheral wall of the opening means 3 from one side thereof,
This is done by separating the first member 4 from the container body 6.

Thus, when the drug application device 1 is unsealed, a part of the drug 5 is exposed in the ejection hole 8 of the drug 5 on the container body 6 side from which the second member 4 is removed. Furthermore, when a part of the container body 6 is pushed out and compressed in the direction of arrow B shown in FIG. 4 in order to positively push out the medicines 5 contained in the container body 6, this pressure is transferred to the pressure transmission member 7 The drug 5 is transmitted to the outside through the discharge holes 8 of the drug applying member 9, and when the necessary amount of the drug 5 is completely discharged, the drug 5 is applied to a necessary portion. Will be possible.

Further, since the tip end portion of the second member 4 separated by unsealing is configured to be hollow (see FIGS. 2 and 3), the open end portion of the second member 4 is connected to the medicine of the container body 6 or the like. Since it can be used as a cap that can be attached to and detached from the discharge side of 5, it can be used multiple times (see FIG. 5).

If the open end of the second member 4 is connected to the other end closed side of the container body 6, as shown in FIG. 6, the total length of the drug application device 1 is increased by the length of the second member 4. Therefore, even when the fingers are in the way and the medicine applying member 9 does not reach, it is possible to apply the medicine 5 or the like to a necessary portion.

In addition, in the present embodiment, the case where the drug 5 or the like is stored has been described, but the present invention is not limited to this, and when the drug 5 or the like is stored in the container body 6 of the drug application device 1 of the present invention, Instead of the drug 5 or the like, cosmetics, detergents, etc. used in daily life may be appropriately stored.

Further, in the present invention, the structure in which the pressure transmitting member 7 is housed inside the container body 6 and the medicine 5 or the like is discharged through the pressure transmitting member 7 has been mainly described, but the container body 6 is sufficiently compressed and deformed. Needless to say, in the case of having the property, the container body 6 may be simply deformed to compress the internal volume and the drug 5 or the like may be discharged.

[Effect of device]

As described above in detail, according to the drug applying device of the present invention, when the second member is separated from the first member to expose the discharge side of the drug etc. of the first member, the container body is compressed and deformed. Since the internal volume is compressed and the drug or the like is discharged from the discharge hole of the drug applying member and the drug or the like is applied to the affected area on the drug applying surface, there is no need for an insertion member that is exposed outside. It is hygienic without touching chemicals directly and can be used with creamy or liquid chemicals. In addition, since it is not necessary to precisely process the outer peripheral surface of the insertion member or the like, the inner peripheral surface of the container body, or the like, manufacturing is easy.

If a pressure transmitting member that deforms or swings in response to the deformation of the container body and is capable of pressing a drug or the like is arranged, the internal volume is efficiently compressed. It is possible to eject the drug almost completely and to use the medicine without waste.

If at least a part of the pressure transmitting member is in contact with the end surface of the drug or the like, the drug or the like can be completely discharged from the discharge hole, and the drug or the like can be used more efficiently.

If the second member is attached to and detached from the side of the container body where the drug or the like is discharged, the drug or the like can be stored and can be reapplied. Therefore, it can be used until all the drug etc.
Drugs are not wasted.

By connecting the second member to the closed side of the other end of the container body, it is possible to apply the drug or the like to a range in which it is difficult for the fingers to reach due to the increase in the total length in the longitudinal direction. Therefore, there is an effect that the usable range of the drug application device is widened and that demand can be expected to expand.
