Improvements in the Manufacture of Bottle Envelopes.
I, JACOB FEIRABEND of Niedernhausen, in Taunus, Hessen Nassau, Prussia,
Paper Maker, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement :-
This invention relates to the manufacture of bottle envelopes to be used in lieu
of the ordinary straw envelopes, by working up paper stock such as cellulose,
woody fibre, rags, straw, paper waste, and the like, into cardboard upon a paper
making or equivalent hydro-extracting machine in the usual way except that the
cardboard is embossed in various patterns, as hereafter described, before or after
leaving the machine but whilst still sufficiently moist (say from 40% to 90% dry
content) by passing it between a pair of embossing rollers having counterpart
raised and sunk surfaces so as to produce small isolated embossings with intervening
flat or unembossed portions. The embossed card is then cut into pieces and dried,
whereby the required strength and elasticity are imparted.
The embossing rollers may be of greater or less diameter according to the
amount of moisture contained in the cardboard, and may be hollow and steam
heated for simultaneously embossing and drying, and they may be adapted to
receive changeable dies whereby a trade name, mark, or other special design, may
be embossed at a certain point upon each piece to form an envelope so that
envelopes may be supplied to the user with his trade designation or mark, etc.,
already embossed thereon.
The material having been embossed, as shewn in Figures 1 and 2, is cut into
V notched blanks of the form shewn in Figure 1 and the bottle envelopes are formed
as shewn in Figure 3 by coiling one or more times upon a mandrel or "former"
and securing the end of the coiled piece by pasting or wire stitching or staples, the
body portion being cylindrical and the neck portion conical as shewn in Figure 3,
by stitching together the tapered parts with wire whereby the bottle when inserted
is prevented from falling out.
The material being embossed when in the moist condition and according to a
pattern such as that shewn, possesses great strength and elasticity and affords pro-
tection against breakage. The permanency of the embossing is due to the isolated
character of the embossed portions, and to the non-extensibility of the intervening
flat or unembossed portions whereby the flattening of the embossings is resisted,
without the necessity of gluing a second sheet of paper to the embossed sheet as is
necessary with corrugated pasteboard.
In order to prevent the bottle falling out of the envelope, the latter is made to
embrace the bottle neck for which purpose it is provided at the top at opposite
sides with two metal clamps whereby its upper aperture is contracted so as to clasp
around the bottle neck when the latter is inserted. To still further protect the
bottle, the envelope may be made double and the inner part project beyond the
other so that when the bottle has been inserted the projecting part of the inner
portion may be folded over the bottom part of the bottle.
The envelope being made of a material which is a bad conductor of heat, affords
great protection against changes of temperature which is increased by making the
envelope longer than the bottle and tucking it into the "kick" in the bottom of
the bottle which is thus entirely enveloped.
These improved envelopes are not liable to become musty, as are straw envelopes,
they afford a much better protection against atmospheric changes, and are cleaner
and superior in annearance

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, I declare that what I
claim is―
1. Bottle envelopes made of raw paper stock cardboard, embossed whilst in a
moist state with isolated embossings, as specified.
2. Bottle envelopes of the kind specified in Claim 1, the blank. being. V-notched
so that the upper part of the envelope is tapered, as described.
3. The herein described method of making bottle envelopes, consisting in
embossing the pasteboard with isolated embossings while still in a moist state,
cutting out the blank, and uniting the edges as specified.
Dated this 19th day of June 1893.
