Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stamp, and more specifically, it is used for the purpose of imprinting on a surface generally made of a material that absorbs ink for stamps, such as paper, cloth, wood, and the like. Is metal, glass,
The present invention also relates to a stamp that is also used for imprinting on a surface (ink non-absorption surface) made of a material that does not absorb stamp ink, such as plastic.

[0002]

2. Description of the Related Art Conventionally, in the case of imprinting on an ink non-absorption surface, a desired character, symbol, figure, etc. (character, symbol, figure, pattern or other expression form) is first formed on a rubber or metal stamp body. A stamp surface is formed by forming one of the above or a combination of two or more thereof into a convex shape. Next, such a stamp body is attached to a part of the stamp body holding holder to make a stamp. The so-called immortal ink (oil-based ink) or quick-dry immortal ink is attached to the stamp surface of the stamp body of the stamp thus manufactured using a stamp stand. Then, the stamp surface of the stamp main body is pressed against an ink non-absorption surface of metal, glass, plastic or the like to be imprinted.

In the case of imprinting a large number of times by such a method, it is necessary to press the stamp surface of the stamp main body against the stamp base to adhere the ink to the stamp surface each time it is imprinted, which is extremely troublesome.

Therefore, the stamp body is made of a material through which the ink for stamping can pass, and this stamp body is attached to a part of the holder for holding the stamp body, and the ink is stored inside the holder. An ink replenishment type stamp has been developed that gradually exudes into the stamp body.

However, in this ink replenishment type stamp, ink oozes out from the entire stamp surface of the stamp body. That is, ink oozes out from both the stamped portion on the stamp surface of the stamp body on which characters, symbols, figures, etc. are formed and the non-printed portion provided at a height lower than this stamped portion.

For this reason, if the imprinted portion cannot be pressed perpendicularly to the surface to be imprinted, or if the area of the imprinted portion is too small compared to the non-imprinted portion, the imprinted portion is formed only at the center of the stamp surface. In this case or when the surface to be imprinted is strongly imprinted, there is a disadvantage that the ink at the non-imprinted portion adheres to the surface to be imprinted.

Further, the ink contained in the holder or impregnated in the stamp body oozes out not only from the imprinted portion of the stamp body but also from the non-imprinted portion.
For this reason, there is a problem that the ink evaporates quickly and the ink must be replenished frequently.

Therefore, the applicant of the present application developed a stamp having the following characteristics in order to solve such a problem, and already applied for it (Japanese Patent Laid-Open No. 4-36328).
Published application as No. 5 publication).

That is, as described in claim 1 of the specification in the above-mentioned publication, the stamp has a stamp face (consisting of a continuous pore body capable of transmitting (passing) the stamp ink (passage)). (Corresponding to the "stamp body" of the present application) and a holder that holds this stamp face and is provided with an ink storage portion inside, the stamp face of the stamp face (corresponds to the "stamp face" of the present application), Letters, symbols,
A marking part in which a figure or the like is formed in a convex shape and which allows ink to penetrate, and a non-marking part which is formed to have a height lower than that of the marking part and which is sealed by heat welding to prevent ink penetration. Further, the stamp face member is attached to one end portion of the holder in a jointed manner, and the joint portion of both is sealed by heat welding.

And in such a stamp,
Paragraph number on page 2 of the specification

It has the actions and effects described in the section [0009]. That is, the non-printing portion is formed by the heat-welding treatment on the printing surface of the printing surface body, because the non-printing portion is formed by melting and solidifying the surface of the continuous pore body with the printing portion formed of predetermined characters, symbols, and figures remaining. In the part, the pores of the continuous pore body are collapsed. Further, the stamp face body is attached to one end portion of the holder in a joined state, and the joined portions of both are melted and solidified by heat welding. Therefore, ink does not ooze out from a portion other than the stamped portion on which predetermined characters, symbols, figures, etc. are formed. Further, since only the imprinted portion of the stamp surface is in contact with the external air, it is possible to minimize the evaporation of the ink from the stamp surface.

[0011]

However, in the stamp described in the above publication, since the stamp body (print face) is attached to one end of the holder in a joined state,
When a plurality of stamps having various shapes and sizes are to be manufactured, a dedicated holder suitable for the shape and size of each stamp body is required. Further, when manufacturing a stamp in which the stamp body protective cap is attached to the holder, a dedicated protective cap suitable for the holder is also required. That is, it is necessary to make one holder and / or one protective cap for one stamp body.

Since the holder and the protective cap are generally made by plastic injection molding, when it is necessary to make one holder and / or one protective cap for one stamp body, the investment amount for that is large. It becomes a thing. In particular, since the cost of manufacturing the injection molding die for making the holder and the protective cap is high, there is a problem that the cost of each stamp as a product becomes high in the case of high-mix low-volume production. It was

The present invention has been made in consideration of the above circumstances, and its main purpose is to prevent unnecessary ink from adhering to the surface to be imprinted and to prevent ink from the stamp body. The object of the present invention is to provide a stamp having a low product cost as well as being capable of performing the stamping continuously and easily and comfortably with a low evaporation rate.

[0014]

According to the present invention, two flat surfaces which are made of a material through which the stamp ink can pass and which can be heat-welded and which are parallel to each other and which are connected to the flat surfaces. And a holder for holding the stamp main body, and one flat surface of the stamp main body has a marking portion through which ink can pass and the marking portion. A non-printing portion that is formed to be lower in height and is sealed by heat welding so that ink cannot pass through, and the other flat surface side of the stamp body is provided with or through a cushioning material. Without
A first holding member is provided, and a second holding member is provided on the stamp body holding side of the holder with or without a cushioning material.
A holding member is provided, and the peripheral surface of the stamp body is sealed by heat welding to prevent ink from passing through.
A stamp in which the stamp body is detachably held by the holder is provided by mutual joining of the first holding member and the second holding member.

[0015]

In the stamp according to the present invention, the stamp surface of the stamp body is made of a material through which the stamp ink can pass and which can be heat-welded-for example, a polyolefin resin.
Is formed by. Then, by the heat-welding process on the stamp surface of the stamp body, the surface of the stamp melts and melts in the state where predetermined characters, symbols, figures, etc. (imprinted part) are left, so that the ink cannot pass through. A marking portion is formed. Therefore, even if the non-imprinted portion of the stamp body comes into contact with the surface to be imprinted, the non-imprinted portion of the stamp body is sealed, and there is no risk of unnecessary ink adhering to the same surface.

Further, since such a non-printing portion limits contact with the external air only to the printing portion on the stamp surface, the evaporation speed of ink from the stamp body becomes slower than in the conventional case. That is, it is not necessary to replenish ink frequently.

Since the stamp body has the marking portion and the non-printing portion on the stamp surface as described above, if the stamp body is impregnated with ink, the marking can be continuously and easily performed. it can.

Further, since the stamp main body is configured to be detachably held by the holder, the stamp manufacturer can support a plurality of stamp main bodies with a general-purpose holder and / or a general-purpose cap under certain conditions. The stamp product cost can be reduced.

In the present invention, the planar shape of the plate stamp main body is arbitrary, such as triangular, quadrangular, other polygonal, circular and elliptical. The material for the stamp body is preferably made of polyolefin resin such as polypropylene or polyethylene. As the holder, for example, a holder made of a polyolefin resin such as polypropylene or polyethylene is used. Usually, the holder is integrally provided with a handle portion to be held by a hand when marking is performed, or a handle is provided as a separate body.

The material of the first holding member provided on the stamp main body and the material of the second holding member provided on the holder are not particularly limited, but the stamp main body is made of a material that can be sealed by heat welding. Considering that it is a tape fastener having a large number of hooks and a tape body having a large number of loops that are detachably locked to the hooks, a surface fastener or a repeated adhesive
It is preferably a peelable double-sided tape. In those cases, the planar shape and size of the surface fastener and double-sided tape are
It is appropriately determined according to the planar shape and size of the stamp body and the holder.

To provide the first holding member on the stamp main body or the second holding member on the holder, for example, an adhesive action such as an adhesive or a double-sided adhesive tape is used. If desired, a cushioning material made of sponge or rubber may be interposed. When these cushioning materials are interposed, the hand is less likely to get tired even when continuous marking is performed when the surface to be marked is hard.

The stamp according to the present invention may include one or more replacement stamp bodies in addition to the stamp body detachably held in the holder. In such a case, the user of the stamp can handle a plurality of stamp bodies with one holder by holding the desired replacement stamp body in the holder instead of the stamp body held in the holder. become.

In the stamp according to the present invention, it is preferable that a protective cap that covers the held stamp body is detachably attached to the holder. In such a case, it is possible to effectively prevent the stamp body from being damaged or the ink from being undesirably evaporated from the stamped portion of the stamp body when not in use.

In the stamp according to the present invention, the first holding member is provided via the cushioning material, and the ink replenishing portion for replenishing the ink to the stamp main body is provided with the first holding member and the cushioning material penetrating therethrough. It is preferably provided.
The ink replenishing portion is composed of, for example, two substantially rectangular openings and three substantially circular openings provided in a state of penetrating the first holding member and the cushioning material by a punching operation using a punch for punching or a punching machine. It In such a case, when the ink needs to be replenished, the stamp main body held by the holder is removed from the holder, and the ink is replenished from the ink replenishing openings in the first holding member and the cushioning material.

A filling member is preferably removably fitted in such an opening. For example, this filling member is made of the same material as the material of the stamp main body, or is formed by stacking the first holding member and the cushioning material and punched when the opening is provided by the above punching operation. To be When such a filling member is fitted into the opening, the inconvenience caused by providing the opening, that is, the first holding member and the cushioning material have a cavity, so that the marking portion of the stamp main body is imprinted at the time of imprinting. It is possible to prevent inconveniences that the stamp body does not come into uniform contact with the surface, and the ink impregnated in the stamp body leaks out from the opening or evaporates.
