ABSTRACT:
This invention relates to ink stamps, ink refills, and ink stamp and ink refill combinations. In particular, the invention relates to ink stamps of the type in which an ink impression is made on a substrate, e.g. a piece of paper, by placing the stamp over the region of the paper to be printed and then resiliently depressing a handle to push an inked surface down onto the paper. An ink stamp of this type is shown in U.S. Pat. No. 4,022,127.
BACKGROUND OF THE INVENTION
Improvements to this type of ink stamp are disclosed in UK Patent Nos. GB 2226276, GB 2226985 and GB 2236981. Contents of the above patent documents are incorporated herein for reference purpose.
When such a prior art ink stamp runs out of ink, fresh ink is introduced directly onto the lower relief printing surface of the stamp. As it takes several hours before the newly-introduced ink is fully and evenly absorbed by the pre-inked stamp, when the stamp is applied on a substrate, e.g. a piece of paper, shortly after the stamp is replenished with ink, more ink than is desirable will be applied on the piece of paper. It is also found in practice that the existing method of replenishing ink to the stamp is cumbersome.
It is thus an object of the present invention to provide an ink stamp, an ink refill, and an ink stamp and ink refill combination, in which the aforesaid shortcomings are mitigated, or at least to provide a useful alternative to the public.
SUMMARY OF THE INVENTION
According to a first aspect of the present invention, there is provided an ink stamp including a body member, wherein said body member includes a base member with edges for resting on a surface to which an inked impression is to be applied, and stamping means to which a stamp member is securable, wherein said stamping means is movable relative to said base member for selectively moving said stamp member into or out of contact with said surface, and wherein channel means extends from an exterior of said stamping means into at least part of said stamping means to thereby allow ink to be supplied to said stamp member.
According to a second aspect of the present invention, there is provided an ink refill including means for containing an ink, said containing means including at least first and second ends, wherein said first end is closable by covering means, and wherein said second end is removable from said ink refill to allow exit of said ink from said containing means.
According to a third aspect of the present invention, there is provided an ink stamp and ink refill combination, including an ink stamp and an ink refill which are releasably engageable with each other.
