Abstract

PURPOSE:To easily and closely bond and fix a stencil to a non-horizontal surface and curved surface of a metal, by closely connecting one or more magnetized stencil wherein a numeral, a character and/or a figure are punched in a flexible magnetized plate to the surface of the metal and applying pint to the surface thereof to perform printing. CONSTITUTION:As a flexible magnetized plate, for example, a plate prepared by uniformly distributing a magnetic iron powder in a plate made of rubber or flexible plastic such as a magnet rubber plate an be utilized and, pref., a magnet rubber sheet covered with a plastic membrane can be utilized. Since a stencil composed of the flexible magnetized plate having a numeral, a character and/or a figure punched therein has magnetism, said stencil can be closely bonded to the total surface of a can, metal box or plate. Since the stencil has flexibility, said stencil closely bonded not only to a flat surface but also to a cured surface to make it possible to print the numeral, the character and/or the figure. That is, no paint penetrates into the gap between the stencil and a surface to be printed by the levitation of the stencil because of close adhesiveness, and the numeral, the character and/or the figure can be accurately printed.

Description

[Detailed Description of the Invention] I! The present invention relates to a magnetic stencil used to draw numbers, letters, or figures on a metal surface such as a can, box, or plate, and a method of printing using the same. It is.

Conventional technology Traditionally used stencils include thin metal plates, thick paper, or hard plastic plates, all of which have little flexibility and cannot be used if the metal surface is not flat. Otherwise, it was difficult to tightly fix it on non-horizontal and curved surfaces.

In addition, when printing a series of numbers, letters, or figures by connecting multiple stencils, it is important to avoid intrusion of paint, etc. from the joints of two or more stencils, and to improve portability. In order to prevent this, the connecting portion must be pasted with adhesive tape, or a stencil with an insertion structure for connecting both edges of the stencil must be used (see Fig. 6), which is inconvenient.

On the other hand, when using these stencils, paint or the like may be scattered around the stencil, causing unnecessary stains on areas other than the printed surface.

Further, after using the stencil, paint adheres to the surface of the stencil, and if it is not washed off with a solvent or the like immediately after use, the paint will stick and the stencil cannot be reused.

Problems to be Solved by the Invention In order to print numbers, characters, or figures on a flat surface or especially a curved surface using a stencil, it is preferable that the stencil is completely in close contact with the flat surface or curved surface. When printing numbers, letters, or figures on an elevation, the stencil must be fixed in some way to prevent it from falling or slipping.

Furthermore, when using a plurality of stencils, it is inconvenient to use these stencils in one piece.

When printing using a stencil, it is necessary to have a printing method that prevents paint from entering through the joints of the stencil, or from scattering paint around the stencil and staining areas other than the printing surface. Furthermore, after using the stencil, it is desired that paint etc. adhering to the stencil can be easily removed and the stencil can be reused.

Means for Solving Problems The present invention provides a magnetic stencil for drawing numbers, letters and/or figures, which is formed by arbitrarily cutting out or punching out a flexible magnetic plate, and a magnetic stencil for drawing numbers, letters, and/or figures, and a magnetic stencil for drawing numbers, characters, and/or figures, and a magnetic stencil for drawing numbers, letters, and/or figures. It is used individually and printed with paint.

The magnetic stencil with numbers, etc. cut out of the present invention can be produced by cutting out numbers, etc. on a ready-made flexible magnetic plate, or by pouring a flexible magnetized material into a mold that creates a shape with numbers, etc. cut out. It can be obtained by, for example, forming a

A specific example of the flexible magnetic plate used in the present invention is a rubber plate such as a magnetic rubber plate or a flexible plastic plate on which magnetic iron powder or the like is uniformly distributed. Preferably, a magnetic rubber sheet whose surface is coated with a plastic thin film can be used.

Furthermore, the stencil of the present invention can be formed, for example, as follows. ■Re-form the edges vertically. Also ■
One or more steps are formed on both edges. In this case, stencils of the same type are used side by side in a partially overlapping state.

Roughly ■ Both edges are tapered at an included or obtuse angle to the surface. In this case, plates of the same type are used side by side in a partially overlapping state. ■In addition to this, various shapes of edges such as wavy and circular shapes can be used.

The method of using the stencil of the present invention is to closely connect one or more stencils to a metal surface, apply paint, etc. to the surface, and print.

The paints used for printing numbers, characters and/or figures of the present invention include paints, inks, etc. in addition to paints.

The printing method may be brush coating, roller coating, spray coating, or the like.

Another method of using the stencil of the present invention is to closely connect one or more stencils, form a detachable thin film on the surface of the stencil, and then integrate the stencil.
This is a method of printing by placing the stencil on the printing surface and applying paint, which allows a plurality of stencils to be easily adhered to each other and integrated.

In addition, the stencil is placed directly on a metal surface either singly or in two or more closely connected, and then a removable thin film is formed on and around the stencil, and then a paint is applied to print. , the paint will not scatter around the stencil and cause unnecessary stains on the printing surface, and the paint attached to the stencil can be easily removed by peeling off the thin film after printing is completed. Can be used again.

To form a detachable thin film, polycellulose,
The coating can be applied by brush coating, roller coating, spray coating, etc. using a solution of a natural or synthetic polymer material such as polyvinyl alcohol or cellulose acetate in alcohol or acetone.

The magnetic stencil according to the present invention can be used on various metal surfaces and magnetic surfaces such as automobiles, cans, toys, and signboards.

Function The first feature of the present invention is a stencil made of a flexible magnetic plate with numbers, letters and/or figures cut out. It's about being in close contact with. In addition, due to its flexibility, it can adhere to not only flat surfaces but also curved surfaces, such as numbers, letters, etc.
Or figures can be printed. In other words, because the adhesion is good, the stencil does not lift up and the paint does not enter the gap between the stencil and the printing surface, allowing numbers, letters, and/or
Or figures can be printed accurately.

Furthermore, since it is a flexible magnetic plate, it can be easily attached to vertical surfaces without requiring any other fixing means, and single numbers and/or figures can be printed accurately.

A second feature of the present invention is that both edges of the stencil of the present invention are formed into alternating steps or a tapered shape, and one or more steps are formed on both edges of the flexible magnetic plate. With these stencils, the connecting parts of two or more similar stencils can be connected in an overlapping state, and the overlapping parts are attracted to each other by opposing magnetic forces and stick together, making it easier to fix, making it easier to fix multiple stencils as if they were one stencil. It can be treated like a stencil. Therefore, since the boundaries connecting adjacent stencils are in close contact with each other due to magnetic force in an overlapping state, there are no gaps, and paint, paint, or ink will not enter through the gaps and create unnecessary lines. , the step at the edge of the magnetic stencil,
It goes without saying that it can be formed into multiple steps, such as two or three steps, as appropriate.On the other hand, the edge of the flexible magnetic plate may be formed in a tapered shape at an included angle or an obtuse angle with respect to its surface. Stencils have a structure in which plates of the same type can be connected by partially overlapping each other, and the overlapped parts adhere to each other due to opposing magnetic forces, making it easier to fix adjacent stencils. can be handled as if it were a single stencil. Furthermore, when the boundaries of flexible magnetic plates of the same type are overlapped and adhere to each other due to magnetic force, there are no gaps, and paint, paint, or ink can enter through the gaps and create unnecessary lines. Furthermore, it is easy to separate a plurality of connected flexible magnetic plates according to the present invention one by one.

The third feature of the present invention is that a removable thin film is formed on the surface of a single stencil or two or more stencils made of flexible magnetic plates closely connected, and then the stencil is placed on the printing surface.
This is a method of printing using paint or the like. (2) Two or more stencils are connected to each other, and the stencils can be easily transported to the printing location and attached or removed in a fixed and integral state. ■The joints between the stencils are coated and the paint does not enter. ■When using the stencil on the printing surface, even if paint scatters around the outside of the stencil, the printing surface is covered by the thin film and the paint does not penetrate. No stains; - After printing is completed, the thin film can be easily peeled off, making it easy to remove paint, etc. adhering to the stencil and other parts of the stencil by removing the thin film. You can reuse the stencil.
