Description

Applicator

The present invention relates to an applicator provided with a cylindrical member such as a shaft cylinder or a cap as a constituent element, and relates to a decorating process for the cylindrical member.

Writing instruments generally include a cylindrical member such as a shaft cylinder or a cap as a constituent element. In addition to writing instruments, correction liquid applicators, liquid cosmetics such as mascara and nail polish, liquid or fluid adhesives, and chemical applicators are also provided with a cylindrical member. There are many things. Hereinafter, it is referred to as “applicator” in this specification, including writing instruments.
In many cases, the surface of the cylindrical member of such an applicator is given some decoration. For example, printing on the outer surface, painting, engraving, line engraving, plating, sticker sticking, etc. can be mentioned as the main methods. In such a decoration process on the outer surface, the decorated part is directly exposed to the outside world, and is accompanied by finger contact at the time of use, so the decorated part may be worn, soiled or peeled depending on the processing method. Sometimes. As a result, fingers may be soiled.

In order to avoid such a decorating process on the outer surface, the cylindrical member is doubled and decorated on the outer side of the inner cylinder, as in the technique disclosed in Patent Document 1 below. Attempts have also been made.

JP 2005-335362 A

Although the above prior art certainly does not require the decoration process on the outer surface, the number of parts increases because the cylindrical member needs to be doubled. In addition, by doubling the cylindrical member, there is a problem that the outer shape of the product becomes larger and the internal capacity becomes smaller than the outer shape of the product.
In view of the above problems, an object of the present invention is to enable a desired decorating process without specifically increasing the number of parts of the applicator and without decorating the outer surface.

In order to solve the above-mentioned problems, the present invention is an applicator provided with a cylindrical member at least partially formed of a light-transmitting material, and is decorated on the inner surface of the cylindrical member. It is characterized by being given.
Here, the “applicator” as used in the present invention refers to a writing instrument such as a ballpoint pen, a sign pen, a marker pen, a mechanical pencil, a fountain pen, a correction liquid, an adhesive, a chemical, or a cosmetic applicator such as mascara or nail polish. Is also included.
The “tubular member” of the applicator means a member that forms an outer shape, such as a shaft tube or a cap, for example, if it is a writing instrument. In the case of an applicator, it refers to a member that forms an outer shape, such as a container or a cap. At least a part of the cylindrical member is formed of a light transmissive material. Here, “light transmittance” means that the inside can be seen from the outside, such as transparent, translucent, and colored transparent. Examples of such “light transmissive material” include synthetic resins such as polyethylene, polypropylene, polycarbonate, and ABS, and glass. And that this cylindrical member is “at least partly light transmissive” means that all or part of the member has such light transmissive property.

And in this invention, by giving the decorating process to the inner surface of this cylindrical member, even if it does not give any decorating process to an outer surface, a desired decorative design is provided to an applicator. It is possible.
Here, various methods can be used as the decorating process. For example, the decorating process may be performed by sticking a pressure-sensitive adhesive sheet with a decorative surface on the inner surface of the cylindrical member. Is possible. Moreover, it is also possible to carry out by sticking a light-transmitting pressure-sensitive adhesive sheet having a decoration on the surface opposite to the pressure-sensitive adhesive surface to the inner surface of the cylindrical member. The decoration on the pressure-sensitive adhesive surface or the surface on the opposite side can be performed by printing, for example. And after apply | coating an adhesive agent to an adhesive surface, it can coat | cover with a peeling sheet and can be set as the adhesive sheet for decorating. If this adhesive sheet for decoration is applied along the inner surface of the cylindrical member to be decorated while peeling off the release sheet, the decoration applied to the adhesive surface or the opposite surface is a cylinder. It will be in the state which adhered to the inner surface of the shaped member. And since a cylindrical member is light transmittance, it is possible to visually recognize the design decorated on the inner surface from the outside.

Also, this decoration process can be carried out by painting the inner surface of the cylindrical member. For example, if a nozzle capable of spraying paint from the tip is inserted into a transparent cylindrical member, and the paint is sprayed while moving the member or nozzle in the axial direction, the sprayed paint is contained in the member. Adhere to the side. The color or pattern of the adhered paint is visible from the outside of the transparent member. This paint is not limited to a normal paint, and a metal foil or the like can be mixed into the paint to provide a decorative treatment that exhibits glitter on the inner surface of the member. In this way, by decorating the inner surface of the member, light from the outside is reflected on the coating film, and the surface of the member is also reflected, thereby exhibiting higher glitter as a member. Is done. Furthermore, since the painted surface is formed on the inner surface, compared with the case of painting on the outer surface, the amount of paint that diffuses to the surroundings and is wasted is greatly reduced, and the painting efficiency is dramatically improved. Furthermore, it is not necessary to consider the adjustment of the painted surface performance such as leveling required when formed on the outer side surface, thereby simplifying the coating process.

The decorating treatment may be carried out as any method selected from the above-mentioned adhesive sheet pasting and coating, transfer, printing, plating, vapor deposition, foil stamping and adhering, or a combination thereof. Is possible. Of course, it is also possible to combine the arbitrary methods or those combinations with the sticking of the above-mentioned decorative adhesive sheet. Here, the “addition” refers to a substance that is different from the cylindrical member to be attached, such as paper, cloth, leather, artificial leather, and CFRP sheet, and is used for decoration purposes. By adhering such an additive to the inner peripheral surface of the cylindrical member 20 with an adhesive or the like, a decoration that can be visually recognized from the outside can be applied.

Since the present invention is configured as described above, it is desirable to provide a cylindrical member that can be visually recognized from the outside without particularly increasing the number of parts of the applicator and without decorating the outer surface. Can be decorated. And since the decoration does not have external contact, there is no fear of abrasion, fouling, peeling, etc., and it does not come into contact with fingers during writing, so that writing is not hindered.

The writing instrument which concerns on embodiment of this invention is shown with side sectional drawing. The axial cylinder in the writing instrument of FIG. 1 is shown with side sectional drawing. FIG. 3 is a sectional view taken along line III-III in FIG. The example of the decoration process to the inner surface of a shaft cylinder is shown. The other example of the decoration process to the inner surface of a shaft cylinder is shown.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a side sectional view showing a writing instrument 10 as an applicator 10 according to an embodiment of the present invention. The writing instrument 10 according to the present embodiment is a mechanical pencil. The latter half of the outer shape of the writing instrument 10 is a cylindrical tube 20 as a substantially cylindrical cylindrical member 20. A clip 21 is integrally formed in the vicinity of the rear end of the shaft cylinder 20. The shaft cylinder 20 is formed by injection molding of transparent polycarbonate.
On the other hand, the first half of the outer shape of the writing instrument 10 is a substantially cylindrical grip portion 22. The grip portion 22 is screwed together with the shaft cylinder 20 to form the outer shape of the writing instrument 10. Further, a substantially conical stainless steel base 30 is attached to the tip of the grip portion 22.

A mechanical unit 40 of a mechanical pencil is built in the internal space formed by the shaft cylinder 20 and the grip portion 22. An eraser 41 is attached to the rear end of the mechanism unit 40, and a cover member 42 covering the eraser 41 projects from the rear end of the shaft tube 20.
As shown in FIG. 2, the shaft cylinder 20 is a substantially cylindrical member provided with a clip 21 in the vicinity of the rear end. As shown in the cross-sectional view of FIG. 3, an adhesive sheet 50 is attached to the inner peripheral surface. As shown in FIG. 4, the pressure-sensitive adhesive sheet 50 is provided with a printed layer 52 having a decorative design printed on the surface of a base material 51 made of polypropylene and formed as a transparent sheet. The adhesive layer 53 is coated with an agent. Note that a paper release sheet 54 for protecting the adhesive layer 53 is further adhered to the upper layer before being attached to the shaft cylinder 20.

When sticking the adhesive sheet 50 to the inner peripheral surface of the shaft cylinder 20, as shown in FIG. 4, if the adhesive layer 53 is attached while peeling the release sheet 54, the inner periphery as shown in FIG. The entire circumference of the surface can be pasted. By sticking the adhesive sheet 50 in this way, the inner peripheral surface of the shaft cylinder 20 can be decorated, and the decorated design can be seen from the outside through the transparent shaft cylinder 20 It is. As shown in FIG. 5, the pressure-sensitive adhesive sheet 50 has a base material 51 formed of a light-transmitting material, a pressure-sensitive adhesive layer 53 on the front surface and a printed layer 52 on the back surface, and an upper layer of the pressure-sensitive adhesive layer 53. Alternatively, the release sheet 54 may be attached to the substrate.

The inner surface of the shaft cylinder 20 used in the embodiment of the present invention may be subjected to a decorating process by painting. An example of such a coating system is schematically shown in FIG.
The shaft cylinder 20 is movable in the axial direction (left and right in the drawing) by the air cylinder 73 while being held by the shaft cylinder holding portion 74. The injection nozzle 70 for injecting the paint is in a position to be inserted along the axial direction into the inner space of the shaft cylinder 20 held in this way. This injection nozzle 70 is connected to a mixing chamber 72 that mixes air A flowing from a compressor (not shown) through the air solenoid valve control unit 75 and the paint from the paint tank 71, and is generated when the paint is mixed with air. Aerosol is ejected from its tip. The air solenoid valve control unit 75 also serves to control the protrusion and immersion of the air cylinder 73.
