Description

  The present invention relates to an applicator for applying various chemical solutions for medical use such as disinfection, sterilization, and treatment, cosmetic use, and cleaning of mechanical parts or electronic parts.

  Conventionally, absorbent cotton is wound around one end of a shaft body, impregnated with a chemical solution such as a disinfectant, and applied to an affected area such as a wound or throat. However, since the operation of winding absorbent cotton and impregnating it with the above chemical solution is complicated, a fiber assembly such as absorbent cotton is attached to one end of the shaft beforehand, and the one impregnated with the chemical solution is not used. It has been proposed to seal and wrap one by one with a breathable film. When this applicator is used, it is possible to unwrap the package, pinch the shaft with a finger, and apply the drug solution directly to the affected area.

However, such an applicator has a problem that the chemical solution is likely to ooze out from the fiber assembly due to external pressure during storage or transportation after manufacture, or due to a temperature change or the like. For this reason, there has been a risk that the exuded chemical liquid may adhere to the surface of the shaft body and dirty hands when the shaft body is taken out.
In order to solve such a problem, it has been proposed to seal and package only the coating liquid impregnated portion (for example, see Patent Documents 1 and 2 below).

  However, in these conventional sealing methods, it is difficult to completely seal the periphery of the shaft projecting from the package, and it is difficult to maintain the airtightness for a long period of time by packaging only the coating liquid impregnated portion. . If the airtightness cannot be maintained, the chemical solution may leak to the outside through the shaft, and the chemical solution may evaporate and the coating solution impregnated part may be dried. is there. Furthermore, in applications where sterilization is important, such as for medical use, when the packaging body is opened and the coating liquid impregnated part is taken out, the coating liquid impregnated part comes into contact with the surface or end of the packaging body to cause contamination. It is required not to be done. However, in the conventional sealing method described above, when the coating liquid impregnated portion is taken out from the package, there are not a few cases where the surface of the package is contacted.

  The applicator 11 includes a coating liquid-impregnated swab 20 provided with a coating liquid-impregnated portion 13 at the end of the shaft body 12, a cup member 14 that accommodates the coating liquid-impregnated portion 13, and a seal for sealing the cup member 14. And a covering film 15.

  The cup member 14 is formed with a concave portion 21 for accommodating the coating liquid impregnated portion 13 and a groove portion 23 for accommodating the shaft body 12 that is continuous from the concave portion 21 and is adjacent to the coating liquid impregnated portion 13. Such a cup member 14 can be usually produced by molding a plastic material, but is not limited thereto.

  The shape of the concave portion 21 is not particularly limited as long as it is a shape that can completely accommodate the coating liquid impregnated portion 13, but in the present embodiment, as shown in FIG. A collar 22 is provided around the opening. Thereby, the joining surface of the covering film 15 becomes large, joining becomes easy, and maintenance of airtightness becomes more reliable.

  The groove 23 may have any shape that can completely accommodate the shaft body 12. Specifically, when the shaft body 12 is accommodated, the shaft body 12 does not protrude above the opening surface of the cup member 14 (groove portion 23) (preferably the cup member 14 (groove portion in the state where the shaft body 12 is accommodated). The opening surface of 23) and the upper surface of the shaft body 12 may be in substantially the same plane).

  In the present embodiment, the shaft body 12 is provided with a projecting portion 12a projecting in a direction orthogonal to the axial direction of the shaft body 12, and the groove portion 23 accommodates the projecting portion 12a. A portion 23a is provided. Accordingly, the swab 20 can be positioned with respect to the cup member 14, for example, avoiding inconveniences such as the swab 20 falling off from the cup member 14 at the time of manufacture and the coating liquid impregnated portion 13 contacting the inner surface of the recess 21. can do. When the protrusion 12a and the protrusion accommodating portion 23a are provided, the protrusion 12a preferably has a shape that does not protrude above the opening surface of the cup member 14 when accommodated in the protrusion accommodating portion 23a. More preferably, the shape is such that the upper surface of the protrusion 12a is substantially flush with the opening surface of the cup member 14 in a state where the protrusion 12a is accommodated in the protrusion accommodating portion 23a.

  In the present embodiment, as shown in FIG. 2, the groove 23 is formed so as to incline upward from the recess 21 toward the outer edge thereof. As a result, the coating liquid impregnated portion 13 is accommodated in the concave portion 21 of the cup material 14 with the tip slightly downwards. In addition, it becomes difficult to contact the surface or end of the coating film 15 and contamination can be prevented more reliably.

At least a part of the groove 23 in which the shaft body 12 is accommodated is filled with a sealing material (not shown) for sealing the inside of the recess 21. With this sealing material, the periphery of the shaft body 12 protruding from the cup member 14 is completely sealed, and further, the upper portion of the cup member 14 is covered with the covering film 15, so that the inside of the recess 21 is reliably sealed in the present invention. Is possible. That is, as in the prior art, when the protruding rod-shaped shaft body is sandwiched between the heat-fusible film or the like in the form of a sheet and heat-sealed, a slight gap will occur around the shaft body, The shaft body 12 is accommodated in the groove portion 23 as in the present invention, and the gap between the shaft body 12 and at least a portion of the groove portion 23 and the shaft body 12 and at least a portion of the covering film 15 are separated by the sealing material described above. By closing the gap, high airtightness can be realized.
In the present embodiment, an adhesive is used as the sealing material, and the shaft body 12 and the groove portion 23 are joined. In this embodiment, an adhesive is used as the sealing material, but the sealing material may be any material that can provide airtightness. For example, an adhesive, an adhesive, various natural resins, or synthetic resins. Etc. can be adopted. Especially, an adhesive agent is preferable at the point which also has the function which fixes the shaft body 12, and a hot-melt-adhesive agent is especially more preferable.
