Improvements in or relating to Stamping or Marking Soap.
A communication by FRANÇOIS HENRY LAVANCHY-CLARKE, of 16, Avenue du Mail,

We, LEVER BROTHERS, LIMITED, of Port Sunlight, near Birkenhead, in the
County of Chester, Soap Manufacturers, do hereby declare the nature of this
invention to be as follows:-
-
This invention has for its object a method of labelling or stamping, or marking,
soap, where it is desired to place an elaborate trademark stamped or the like on
the soap. The difficulty of using intricate trademarks on soap hitherto has been
that it is impossible to stamp them and to show them clearly when they are
stamped as the soap being of a soft nature, any finely drawn device is at once
blurred.
Now by this invention we are enabled to mark the soap with any intricate design
required, and in such a manner that it cannot be removed except with great diffi-
culty until the soap is actually used.
66
The invention consists in forming the trademark or stamp of paper preferably
of a bibulous nature and printed in any required manner. The paper is placed
on the bar before stamping, preferably at the point where there is a division when
it is formed into two cakes united together. The main field of the stamp conse-
quently is on the smooth edges while the ends extend over into the field of the
ordinary mark, such for instance as Sunlight soap." This ordinary mark con-
sequently appears embossed on the edges of the stamp and the stamp being
embossed in this way is far more difficult of removal. The paper consequently
can be made either with gun or without it, as the soap itself adheres strongly to
the paper. It is obvious that any material of somewhat similar nature to paper
could be used instead of paper itself such as gelatine for instance, and that trans-
parent as well as opaque papers can be used and thus a great variety of effects
produced. In our case the paper can be placed over the entire upper surface of
the soap, but we do not recommend this.

We, LEVER BROTHERS, LIMITED, of Port Sunlight, near Birkenhead, in the
County of Chester, Soap Manufacturers, do hereby declare the nature of this

described and ascertained in and by the following statement:-

:
This invention has for its object a method of labelling or stamping, or marking
soap, where it is desired to place an elaborate trademark stamped or the like on
the soap. The difficulty of using intricate trademarks on soap hitherto, has been
that it is impossible to stamp them and show them clearly when they are stamped,
as the soap being of a soft nature any finely drawn device is at once blurred.
Now by this invention we are enabled to mark the soap with any intricate design
required, and in such a manner that it cannot be removed except with great
difficulty, until the soap is actually used, and in many cases it appears as if the
mark was actually printed on the soap itself.
The invention consists in forming the trademark or stamp of a paper label
preferably of a bibulous nature and transparent, and printed in any required
manner. This label is placed on the bar before stamping, preferably in such
position that part or whole of the intaglio or other mark or printing of the die
shall come over the label. Where, as in Sunlight soap, for instance there are
twin tablets joined together, we prefer to form the label so as to extend over from
the central field of one tablet to the central field of the next. When then the
tablet is stamped, especially if the label fits any divisions therein, the label looks
as if it was formed in the soap itself and it cannot be easily taken off the soap
owing to it being embedded in the relief or intaglio device stamped in the soap.
The ordinary mark of the soap stamper thus appears embossed on the label and
the label being embossed in this way is more difficult of removal.
Where only a single tablet is stamped, the label may be of such size and shape
that it shall just fit into the recess in the tablet forming the central field. By
this means the label appears to be formed of soap and in the soap, and it is almost
impossible to pick it off, as the edges are at the base of a nearly vertical wall of
soap on the outside. The paper can be made either with gum or without it, as
the soap itself adheres strongly to the paper. It is obvious that any material of
somewhat similar nature to paper could be used instead of paper itself, such as
gelatine for instance, and that transparent as well as opaque papers can be used
and thus a great variety of effects produced. The paper can be placed over the
entire upper surface of the soap, but we do not recommend this.
To illustrate the invention, a drawing is appended in which:-
Figure 1 shows a section of a twin cake of Sunlight soap united together with
the label exaggerated in thickness in order to show it plainly placed on it. A is
the label which is placed on the cake B before stamping, preferably at the
points a where there is a division. C are the embossed letters. The main field
of the stamp or label consequently is on the smooth edges a, while the ends extend
over the field of the ordinary marking or inscription, such for instance as
66 Sun-
light soap." This ordinary mark consequently appears embossed on the edges or
ends of the stamp or label, which being embossed in this way is far more difficult
of removal.
Figure 2 is a single tablet, in which case the main field of the tablet carrying
the label A, may be smooth or in intaglio instead of embossed, but merely embossed
or elevated round the edges so as to more perfectly embed the label in the soap.
The label A is of such size and shape that its edges fit in the edges a¹ of the
elevated part a surrounding the field, while the printed matter on the label appears
on the field. There is thus a raised wall of soap a immediately surrounding the
label, and the label consequently looks as if it were printed on the soap, and it is
very difficult to get anything under the edge of the label so as to pull it off.
The labels in either example should be made of material which will pull out a
little under the press without breaking, and for this purpose therefore elastic
paper or paper put on damp is preferably used.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to us by
cur foreign correspondent, we declare that what we claim is:-
1. The improvement in or relating to stamping or marking soap, which con-
sists in placing upon the soap before stamping, a label of transparent, translucent
or bibulous material of a tough and yielding nature such as paper or gelatine
previously printed in any required manner, and then pressing or embossing the
soap in the usual manner.
2. As a new article of manufacture, a tablet or cake of soap having a label
thereon and a stamped impression forming letters or devices in both the label and
the soap, substantially as described.
3. The improvement in the process of stamping or marking soap referred to in
Claim 1, which consists in arranging the edges of the label to coincide with the
edges of the depression in the stamping, whereby it is much more difficult to
remove the label from the soap,
4. As a new article of manufacture, the combination of a tablet or cake of
soap, a label, and a depression pressed into both the label and the soap on the
edges of the label, whereby there is a raised wall of soap immediately surrounding
the label, and it is very difficult to get anything under the edge of the label so as
to pull it off, substantially as set forth.
