Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hygienic and easy-to-use single-use applicator containing a drug, which is provided with a member that comes into contact with a target part such as an affected part.

[0002]

[Technology of US]

 As a container for containing a drug, a container having not only a simple storage function but also a coating function is known.

Examples of the container having such a coating function include a container for disinfectant having a spraying function, a container for eye drops having a function of dropping each drop, and a stiff shoulder provided with a sponge having a liquid passing function at a discharge port. Examples include containers for therapeutic drugs.

In these containers, the amount of the drug used for one application is smaller than the amount of the contained drug, and the container is often stored for a long time after opening. Therefore, in the case of eye drops, etc., preservatives and the like are added so that the chemicals do not easily deteriorate during the period. However, it may still be discarded without being used up.

On the other hand, in International Publication No. WO89 / 05695, a liquid applicator including a container for containing a liquid and an application member held in the container and capable of applying the liquid to an applied portion. In addition, the coating member is provided so as to be movable inward and outward of the container, and an elastic body that elastically elastically spreads the coating member outward is provided so that the coating member resists the elastic force of the elastic body. The liquid applicator is configured so that the liquid is leached onto the outer surface of the container of the application member by being pushed into the container. In addition, the application member is made of a material having liquid permeability, and has a shape that allows the sealing member to be fitted into the container body again after being separated from the container body. It also describes that it can be used in tools, cosmetic liquid applicators, etc.

[0006]

[Problems to solve problems]

 The container having the above-mentioned application function cannot be strictly resealed once opened, and it is likely to come into contact with the outside air each time it is reused, which facilitates the deterioration of the drug. Therefore, absorbent cotton or the like may be required separately to absorb blood or excess chemicals, and such absorbent cotton or the like is generally uniform and cannot be selected according to its usage form. There is a problem.

On the other hand, the liquid applicator of International Publication No. WO89 / 05695 is superior in that the amount of the drug enclosed is smaller than before and that it can be applied without separately preparing an applicator member such as absorbent cotton. However, since the coating material has absorbed a supersaturated amount of the drug before the use, the encapsulated drug tends to come out too much in the initial stage. In addition, since the function of the elastic body is expressed through the application member, it is necessary to set the material of the application member to be hard, and for example, when the nerve is directly touched by a scratch or the like, the affected area may be stimulated. Therefore, there is room for improvement, such as the need to separately prepare absorbent cotton to absorb blood and extra chemicals.

In view of the above situation, the present invention includes a contact member that comes into contact with a target portion, and it is possible to select an optimum material for the contact member in consideration of applicability. It is an object of the present invention to provide an easy-to-use applicator containing a drug, which can be applied directly to the target area.

The shape of the discharge port (2) provided in this way is arbitrary, such as a circle, an ellipse, or a star. In addition, the number of discharge ports (2) is often one, but it is also possible to provide a plurality of holes as a group if necessary.

The contact member (3) is arranged and fixed to the peripheral edge of the discharge port (2) so that the tip of the contact member (3) projects beyond the discharge port (2). This point is a device point which is the point of the present invention.

The material used for the contact member (3) is often a cloth-like material, a fibrous material, a brush-like material, a cotton-like material, a sponge-like material, a porous material, or the like. If it is not necessary to absorb, non-absorbent structures such as filament bundles, O-rings and beads can be used. There is no particular limitation on the material.

The contact member (3) can be arranged at one or more locations on the periphery of the discharge port (2), or on the entire periphery, but discharge is performed in consideration of efficient absorbability and coatability. It is especially preferred to arrange it over the entire periphery of the outlet (2).

As a method of fixing the contact member (3), a method of holding a contact member (3) between the main body (1) and / or the discharge port (2) by providing a protrusion or a taper, or using an adhesive is used. Any method such as a method, a method of heat-sealing, a method of engaging, and the like can be adopted. It is also possible to use a method of fixing the cartridge to which the contact member (3) is fixed to the main body (1) and / or the discharge port (2). At this time, the fixing strength must be such that it does not slip off or peel off during use.

The applicator of the present invention has a discharging function. Examples of the method of expressing the discharge function include a method of using a pressing force such as a dropper or a bellows, a method of using a physical structure such as a piston mechanism, etc. The method used is preferred.

The applicator of the present invention may have any shape as long as it satisfies the above-mentioned discharge function. For example, in addition to geometrical shapes such as a cylindrical shape, a conical shape, and a tube shape, fish, elephants, flowers, etc. It can be made into a shape that resembles the existing appearance of animals and plants such as, stars, and characters.

The single-use applicator containing a medicine of the present invention may be provided with a protective member (4) for covering the discharge port (2) and / or the contact member (3).

Examples of the protective member (4) include a screw-type or rubbing-type lid, a film, and a bag. At this time, the protective member (4) can also serve as the opening means of the accommodating portion (1) if necessary. For example, a method of providing a protrusion inside the lid described above or a part of the film described above is accommodated. An example is a method of integrating it as a part of the wall that constitutes part (1).

As the material of the protective member (4), in the case of a lid, the same kind as or a different kind from the accommodating part (1) can be used, and when a film is used, the accommodating part (1) can be used. ) A heat-fusible resin should be used in the part that is integrated with.

Examples of the drug (A) include various medicines or quasi drugs such as disinfectants, eye drops, antipruritic agents, blood circulation promoters, stomatitis medicines, athlete's foot medicines, lip creams, hand creams, and the like. Cosmetic agents such as nail polish, emulsion and moisturizer are listed.

[0029]

[Action]

 Since the single-use applicator with a drug of the present invention can be applied to the target portion from the discharge port (2) without going through the contact member (3), the contact member (3) considers the permeability of the drug (A). There is no need, and it is possible to effectively select a material having only the function that matches the purpose of use of the applicator. For example, when the target area is a wound, it is required to have a function of efficiently absorbing excess drug (A) and blood of the affected area, and a function of softening the skin texture and reducing irritation to the wound. Select a material that is highly flexible and has good absorbability, and if the target part is an insect-repellent part, it is required to have a function with good application of the drug (A). Select a material with low absorbency.

Since the contact member (3) is provided on the peripheral portion of the ejection port (2), it is possible to easily follow the application of the drug (A), and the tip is on the front side of the ejection port (2). Since it is arranged so as to project toward, it is not necessary to take care so that the discharge port (2) does not directly contact the target portion during use.

Since the drug (A) and the contact member (3) do not come into contact with each other before use, there is no risk of the material of the contact member (3) being altered by the drug (A), and the drug (A Only) can be stored in a sealed manner, so hygiene management is easy.
