INHALANT PACKAGE
Abstract
A wrapper having a central absorbent area is wrapped around a
frangible ampoule containing an inhalant. The absorbent area
substantially surrounds the ampoule, and the wrapper projects from
the opposite ends of the ampoule. A pressure sensitive adhesive on
the inner surface of the wrapper around its central area sticks the
inner end of the wrapper to the ampoule and also sticks the outer
end of the wrapper to its own outer surface. The projecting portion
of the wrapper at each end of the ampoule is flattened on itself to
form flat layers of wrapper stuck together by the adhesive. The
portion of the wrapper surrounding the ampoule is porous so that
when the ampoule is broken fumes or vapor therefrom can escape
through the wrapper.

Claims
I claim:
1. An inhalant package comprising a frangible ampoule containing an
inhalant, a wrapper having inner and outer surfaces and inner and
outer ends and a central absorbent area spaced inwardly from the
edges of the wrapper, the wrapper being wrapped around the ampoule
in engagement therewith and projecting from the opposite ends of
the ampoule, and a pressure sensitive adhesive on the inner surface
of the wrapper at the opposite ends thereof and along its opposite
sides, the adhesive surrounding said absorbent area, the adhesive
at the inner end of the wrapper sticking to the ampoule and the
adhesive at the outer end of the wrapper sticking that end to the
outer surface of the wrapper, the projecting portion of the wrapper
at each end of the ampoule being flattened on itself to form flat
layers of the wrapper stuck together by the adhesive, and the
portion of the wrapper surrounding the ampoule being porous.
2. An inhalant package according to claim 1, in which said wrapper
is formed from a label and a layer of absorbent material secured to
the inner surface of the label and spaced inwardly from the edges
thereof, and said adhesive is carried by the inner surface of the
label around said absorbent material.
3. An inhalant package according to claim 2, in which said
absorbent material is a separate pad, and said adhesive extends
under the edges of the pad to stick the pad to the label.
Description
Glass ampoules or vials containing a liquid that will vaporize or
give off fumes when released are known. One of the most common
ampoules is the ammonia inhalant ampoule. To protect the fingers
from injury when the ampoule is broken or crushed and to absorb the
released liquid, it is customary to enclose the ampoule in a
flexible absorbent cover. A label, carrying information regarding
the contents and use of the ampoule, is wrapped around the cover.
The cover and the label are applied to the ampoule in succession
and therefore require two different operations.
It is an object of this invention to provide an ampoule or the like
with a special wrapper that not only encloses or covers the
ampoule, but also serves as a label. Another object is to provide
an inhalant package that can be quickly assembled.
The invention is illustrated in the accompanying drawings, in
which
FIG. 1 is a fragmentary plan view showing a number of ampoule
labels carried by a tape;
FIG. 2 is a view of the reverse side of one of the labels;
FIG. 3 is a perspective view showing the beginning of the wrapping
of an ampoule in a label;
FIG. 4 is a perspective view of the label completely wrapped around
the ampoule;
FIG. 5 is an enlarged end view of FIG. 4;
FIG. 6 is a perspective view of the completed package;
FIG. 7 is a perspective view showing the beginning of the wrapping
of an ampoule in a modified embodiment of the invention;
FIG. 8 is an enlarged end view of the wrapped ampoule; and
FIG. 9 is an end view of the completed package.
Referring to FIGS. 1 and 2 of the drawings, a tape 1 of indefinite
length carries a plurality of rectangular labels 2 that are stuck
to the tape by a pressure sensitive adhesive previously applied to
the labels, the surface of the tape being such that the labels can
readily be peeled away from it. Each label carries the usual
information (not shown) applicable to the ampoule to which the
label is to be applied. Applied to the back or inner surface of
each label is a thin layer of absorbent material 3. This layer also
is rectangular, but considerably smaller than the label so that it
will be spaced inwardly from all four edges of the label. The label
and absorbent material form an ampoule wrapper. The absorbent
material may be fabric, fiber, foamed synthetic resin or a resinous
pad formed by applying a liquid resin to the label and then curing
it to form absorbent material. If the absorbent material is in the
form of a separate pad as shown, it is held in place by slightly
overlapping the inner edge of a band of the pressure sensitive
adhesive 4 that extends around the marginal portion of the label.
It is this adhesive that temporarily holds the label on the tape.
The label may be cloth, but if it is impervious material such as
paper, the area of the label covering the absorbent pad is provided
with perforations 5 so that fumes or vapors can penetrate the
label. This area likewise could be covered with the adhesive, but
it is preferred not to do so in order to be sure that the
perforations will not be clogged by adhesive.
To make the inhalant package, a vial or ampoule 7 (FIG. 3) of glass
or other frangible material is filled with the liquid, such as
ammonia, that will provide the desired inhalant. The ampoule may be
cylindrical or oval in section. Its opposite ends generally will be
rounded or more or less pointed. The ampoule is substantially the
same length as absorbent pad 3. The label with its absorbent pad is
stripped from the carrying tape 1 and placed face down on a
support. The ampoule then is laid on the adhesive band at one side
of the absorbent pad. As shown in FIG. 3, this will be the inner
end of the label that will stick to the ampoule and follow it as it
is rolled across the pad to wrap the label around the ampoule. The
label is just long enough for its outer end to overlap its inner
end so that the adhesive at the outer end will stick to the outside
of the inner end of the label as shown in FIG. 5. At this time the
package has a cylindrical appearance as shown in FIG. 4, with the
label projecting from the opposite ends of the ampoule.
The only further operation required to complete the package is to
pinch together the projecting portion of the label at each end of
the ampoule in order to flatten it on itself so that there will be
flat layers of label stuck together by the adhesive as shown in
FIG. 6. The operations just described are readily susceptible to
being automated. There is only the one wrapping operation and the
single cover for the ampoule. No additional label is required for
the package because all of the necessary information can be printed
on the flat label before it is applied to the tape. When the
package is struck or pinched or bent to crush or break the ampoule,
its contents are released and will saturate the absorbent pad, from
which they will vaporize and escape through the perforations 5 in
the label so that the fumes can be inhaled.
In the modification shown in FIGS. 7 to 9, the wrapper is made in
one piece instead of from two pieces stuck together. Also, in this
case the wrapper 10 is a rectangular piece of cloth or porous
fabric that is long enough to be wrapped around an ampoule 11 a
sufficient number of times to provide the desired absorbency for
the inhalant when the ampoule is broken. Like the label in the
first embodiment, the marginal area of the inner surface of the
wrapper carries a pressure sensitive adhesive 12. The ampoule is
rolled up in the wrapper, the inner end of which sticks to the
ampoule and the outer end of which sticks to the outer surface of
itself as shown in FIG. 8. The projecting ends of the wrapper then
are squeezed together to flatten them as shown in FIG. 9. The outer
surface of the fabric wrapper can carry the printed matter desired
for labeling the package.
According to the provisions of the patent statutes, I have
explained the principle of my invention and have illustrated and
described what I now consider to represent its best embodiment.
However, I desire to have it understood that, within the scope of
the appended claims, the invention may be practiced otherwise than
as specifically illustrated and described.
