ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a stack of self-stick writing notes, more particularly to a stack of self-stick writing notes having a plastic sheet with labeling tabs attached thereto.
2. Description of the Related Art
Self-stick writing notes have become popular in recent years since they can be attached on a surface of a table, a wall, a book or a document as desired for reminding purposes.
FIG. 1
illustrates a stack
1
of conventional self-stick writing notes
10
. The stack
1
includes a bottom paper
11
disposed at the bottom thereof for protection of the bottom one of the writing notes
10
from dirt or damage. However, the stack
1
of the conventional self-stick writing notes
10
suffers from the drawback in that the bottom paper
11
is made of a thick paper, which is not water-proof and which tends to be damaged due to its insufficient mechanical strength, thereby losing its ability to protect the writing notes
10
. Furthermore, when the writing notes are applied on a large amount of documents, it becomes more difficult to identify and to trace these writing notes.
SUMMARY OF THE INVENTION
Therefore, it is an object of the present invention to provide a stack of self-stick writing notes that has high mechanical strength and that has a water-proofing ability. In addition, the stack of self-stick writing notes of this invention permits labeling, such as indexing, classifying, giving priority and the like, of documents to be worked on.
According to the present invention, a stack of self-stick writing notes comprises: a plurality of self-stick writing sheets, each of which includes a layer of removable pressure sensitive adhesive, the writing sheets being disposed one above the other to form a stack; a plastic sheet attached to a bottom of the stack, and a plurality of labeling tabs, each of which includes a layer of removable pressure sensitive adhesive attached to the plastic sheet.
