Description

Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a stamp cap for covering a stamp face mounted on a stamp, and more particularly to an ink for attaching ink to the stamp face when the cap is attached. The present invention relates to a seal cap having a pad on a bottom surface. 2. Description of the Related Art A stamp in which a stamp surface is directly engraved on a stamp material such as plastic or wood, and a stamp stamp in which a non-porous rubber print body serving as a stamp surface is attached to the stamp material have been widely known for a long time. However, in this type of stamp, it is necessary to separately prepare vermilion or a stamp stand when using the stamp, and there is also an inconvenience that the stamp cannot be used immediately when there is no vermilion or stamp stand around the desk. In view of the above, there has been known a stamp cap for covering the stamp face of this type of stamp, in which an ink pad impregnated with ink is provided on the bottom face of the cap. And the like. In this type of stamp cap, an ink pad is generally fixed to the bottom surface of a plastic cap with an adhesive. By attaching the stamp cap with this ink pad on the bottom to the stamp, the ink pad of the stamp cap contacts the stamp surface when the stamp is not used, and the ink adheres to the stamp surface.
When using a stamp with the stamp cap attached, the stamp can be stamped immediately by simply removing the stamp cap without preparing a vermilion or stamp stand. [0003] On the other hand, in recent years, environmental problems have been highlighted, and promotion of recycling such as reduction of garbage and reuse of waste plastic has been advocated in various fields. As a result, companies and households are also obliged to separate and discard garbage according to the type and material of the garbage. The stamp cap with the above-mentioned ink pad is of course different from the material of the ink pad and the cap, and the ink pad is impregnated with ink. It is necessary to separate the cap and the ink pad impregnated with the ink. However, the conventional seal cap does not consider separation and disposal at all, and since the ink pad is fixed to the bottom of the cap with an adhesive, it is very difficult to separate the cap and the ink pad. In this case, there is a problem that the ink adheres to the hand and becomes dirty. Accordingly, the present invention provides a stamp cap having an ink pad, in which a plastic cap and an ink pad impregnated with ink can be easily separated without soiling hands and clothes, thereby enabling separation and disposal. It is an object of the present invention to provide a stamp face cap. [0005] In order to solve the above-mentioned problems, the present invention provides a stamp cap having a bottom face provided with an ink pad which is in contact with the stamp face of the stamp when attached to the stamp. Inside the opened box-shaped plastic outer cap, the upper and lower end faces are open, and the lower inner side is made to be a pad housing portion, and the upper side is made up of a stamp mounting portion. An ink pad is provided in the pad accommodating portion located on the bottom surface side with its upper end surface exposed, so that the ink pad is normally inseparable at the bottom surface of the outer cap, and the outer cap and the inner cap are separated. In this case, the ink pad can be separated from the stamp pad. Embodiments of the present invention will be described below in detail with reference to the drawings. Reference numeral 1 denotes a rectangular and square stamping surface cap, which comprises an outer cap 2, an inner cap 3, and an ink pad 4, as shown in FIG. The outer cap 2 is made of plastic and has a rectangular box shape with an open upper end as shown in FIG. 2, and a convex portion 5 protruding outward is provided on the outer surface of the upper end of the peripheral wall 2a in an annular shape.
