An object of this invention is to provide a nasal dilator comprising a release liner divided into three pieces and whose longitudinal middle piece is not removed from an adhesive substance layer when longitudinal end pieces are removed from the adhesive substance layer. The object is achieved by a nasal dilator comprising a release liner divided into three pieces, wherein surface of each of longitudinal end pieces opposing the adhesive substance layer is treated with a release agent and surface of a longitudinal middle piece opposing the adhesive substance layer is not treated with release agent.
Description
This
invention relates to a nasal dilator.
invention relates to a nasal dilator.
In
Patent Literature 1, the applicant of this application proposed a nasal dilator
comprising a flexible strip, an adhesive substance layer formed on one major
surface of the flexible strip and a release liner covering the adhesive
substance layer, wherein the adhesive substance layer is formed on entire
surface of said one surface of the flexible strip, the release liner is divided
into three pieces, a first of which covers one longitudinal end region of the
adhesive substance layer, a second of which covers longitudinal middle region
of the adhesive substance layer and a third of which covers another longitudinal
end region of the adhesive substance layer, and wherein the first piece and the
third piece of the release liner are removed from the adhesive substance layer
and the second piece of the release liner is left adhering to the longitudinal
middle region of the adhesive substance layer at the time of use of the nasal
dilator.
When
the nasal dilator is used with both of the longitudinal end pieces, i.e. the
first and the third pieces, of the release liner removed from the adhesive
substance layer and the longitudinal middle piece, i.e. the second piece, of
the release liner left adhering to the adhesive substance layer, the
longitudinal middle piece of the release liner abuts the top region of the nose
bridge and the adhesive substance layer does not adhere to the top region of
the nose bridge. Therefore, the adhesive substance layer does not peel skin of
the top region of the nose bridge and the top region of the nose bridge is not
damaged when the nasal dilator is removed from the nose bridge. It suffices to
divide the release liner into three pieces and no dedicated member is necessary
for preventing adhesion of the adhesive substance layer to the top region of
the nose bridge.
comprising a flexible strip, an adhesive substance layer formed on one major
surface of the flexible strip and a release liner covering the adhesive
substance layer, wherein the adhesive substance layer is formed on entire
surface of said one surface of the flexible strip, the release liner is divided
into three pieces, a first of which covers one longitudinal end region of the
adhesive substance layer, a second of which covers longitudinal middle region
of the adhesive substance layer and a third of which covers another longitudinal
end region of the adhesive substance layer, and wherein the first piece and the
third piece of the release liner are removed from the adhesive substance layer
and the second piece of the release liner is left adhering to the longitudinal
middle region of the adhesive substance layer at the time of use of the nasal
dilator.
When
the nasal dilator is used with both of the longitudinal end pieces, i.e. the
first and the third pieces, of the release liner removed from the adhesive
substance layer and the longitudinal middle piece, i.e. the second piece, of
the release liner left adhering to the adhesive substance layer, the
longitudinal middle piece of the release liner abuts the top region of the nose
bridge and the adhesive substance layer does not adhere to the top region of
the nose bridge. Therefore, the adhesive substance layer does not peel skin of
the top region of the nose bridge and the top region of the nose bridge is not
damaged when the nasal dilator is removed from the nose bridge. It suffices to
divide the release liner into three pieces and no dedicated member is necessary
for preventing adhesion of the adhesive substance layer to the top region of
the nose bridge.
The
surface of the release liner opposing the adhesive substance layer is treated
with a release agent such as silicone resin or the like so as to be easily
removed from the adhesive substance layer.
Removal
of the release liner from the adhesive substance layer is difficult if the
release liner extends flat. Therefore, most users remove the first and the
third pieces of the release liner from the adhesive substance layer by pinching
one longitudinal end of the nasal dilator with the left hand thumb and
forefinger and the other longitudinal end of the nasal dilator with the right
hand thumb and forefinger, and then bending the nasal dilator in a direction
out of the plane so that the release liner side surface becomes convex. This
procedure is the same as that when a user removes the release liner from the
adhesive substance layer of a conventional nasal dilator comprising a release
liner which is divided into two pieces.
The
surface of each of the first and the third pieces of the release liner opposing
the adhesive substance layer is treated with a release agent so that its
adhesion power to the adhesive substance layer is not large. Therefore, one
longitudinal end of each of the first and the third pieces of the release liner
close to the longitudinal middle of the nasal dilator where curvature is sharp
cannot follow deformation of the adhesive substance layer and detaches from the
adhesive substance layer.
The
user pinches the longitudinal end of each of the first and the third pieces of
the release liner after they detach from the adhesive substance layer and
removes them entirely from the adhesive substance layer.
The
surface of the second piece of the release liner opposing the adhesive
substance layer is also treated with the release agent. Therefore, when the
aforesaid removing procedure of the first and the third pieces of the release
liner is carried out, the second piece of the release liner covering the
longitudinal middle of the adhesive substance layer where curvature is sharp
also detaches from the adhesive substance layer at one longitudinal end and is
left adhering to the adhesive substance layer in a narrow zone at the other
longitudinal end. Thus, adhesion power of the second piece of the release liner
to the adhesive substance layer extremely decreases. (When a user pinches one
longitudinal end of the nasal dilator with the left hand thumb and forefinger
and the other longitudinal end of the nasal dilator with the right hand thumb
and forefinger, and then bends the nasal dilator in a direction out of the
plane so that the release liner side surface becomes convex, the resulting
deformation is liable to become asymmetrical and curvature of the nasal dilator
is liable to become sharpest at a location slightly apart from the longitudinal
middle. As a result, the second piece of the release liner is liable to detach
from the adhesive substance layer at one end close to the location of sharpest
curvature).
When
one longitudinal end of the second piece of the release liner detaches from the
adhesive substance layer, fingers trying to pinch the first or the third piece
of the release liner are liable to make interfering contact with the
longitudinal end of the second piece detached and raised from the adhesive
substance layer. Thus, the second piece of the release liner, whose adhesion
power has already decreased extremely, is liable to be removed from the
adhesive substance layer as a whole or turn upside down to be dislocated from
the correct position.
When
the second piece of the release liner is long, the end left adhering to the
adhesive substance layer is somewhat apart from the location of sharpest
curvature so that it adheres to the adhesive substance layer over a relatively
wide zone. On the other hand, when the second piece of the release liner is
short, the end left adhering to the adhesive substance layer is close to the
location of sharpest curvature so that it adheres to the adhesive substance
layer over only a narrow zone. Therefore, adhesion power of the second piece of
the release liner to the adhesive substance layer becomes smaller in proportion
as the second piece of the release liner is shorter, so that the second piece
of the release liner becomes more liable to be removed by some kind of external
force.
When
the nasal dilator is bent out of the plane with the second piece held in place
by a finger, the aforesaid problem does not occur. However, when a user removes
the first and the third pieces of the release liner from the adhesive substance
layer, the user usually pinches one longitudinal end of the nasal dilator with
the left hand thumb and forefinger and the other longitudinal end of the nasal
dilator with the right hand thumb and forefinger, and then bends the nasal
dilator in the direction out of the plane so that the release liner side
surface becomes convex. The aforesaid problem is therefore liable to occur.
Therefore,
an object of this invention is to provide a nasal dilator comprising a flexible
strip, an adhesive substance layer formed on one major surface of the flexible
strip and a release liner covering the adhesive substance layer, wherein the
adhesive substance layer is formed on entire surface of said one surface of the
flexible strip, the release liner is divided into three pieces, a first of
which covers one longitudinal end region of the adhesive substance layer, a
second of which covers longitudinal middle region of the adhesive substance
layer and a third of which covers another longitudinal end region of the adhesive
substance layer, wherein the first piece and the third piece of the release
liner are removed from the adhesive substance layer and the second piece of the
release liner is left adhering to the longitudinal middle region of the
adhesive substance layer at the time of use of the nasal dilator, and wherein
removal of the second piece of the release liner is prevented when the first
and the third pieces of the release liner are removed from the adhesive
substance layer.

As
shown in Fig. 1, anasal dilator 1 in accordance with a preferred embodiment
comprises aflexible strip 2, an adhesive substance layer 3 formed on one major
surface of theflexible strip 2 and a release liner 4 adhering to and covering
theadhesive substance layer 3. The flexible strip 2 is a single or composite
material member made of paper, cloth, plastic or the like. Therelease liner 4
is made of paper, plastic, or the like. Theadhesive substance layer 3 is
formed on entire surface of said one surface of theflexible strip 2. The
release liner 4 is divided into three pieces, namely, a first piece 4a covering
one longitudinal end region of theadhesive substance layer 3, a second piece
4b covering longitudinal middle region of theadhesive substance layer 3 and a
third piece 4c covering another longitudinal end region of the adhesive
substance layer 3.
A
surface of each of thefirst piece 4a and the third piece 4c of the release
liner 4 opposing the adhesive substance layer 3 is treated with a release agent
such as silicone resin or the like. A surface of thesecond piece 4b of the
release liner 4 opposing the adhesive substance layer 3 is left partially or
wholly untreated with release agent or is treated with the release agent and
then subjected partially or throughout to roughness enhancing treatment by
applying rough surface machining such as scraping, sandpapering, grinding or
sand blasting. Therefore, affinities between the first andthird pieces 4a and
4c and theadhesive substance layer 3 are small and affinity between the second
piece 4b and the adhesive substance layer 3 is larger than those of the first
piece 4a and the third piece 4c. The surface roughness enhancing treatment can
be carried out at the time of production of the paper, plastic or the like of

When
thenasal dilator 1 is used, the first piece 4a and the third piece 4c of the
release liner 4 are removed from the adhesive substance layer 3, the second
piece 4b of the release liner 4, which is left adhering to the longitudinal
middle region of theadhesive substance layer 3, is abutted on a top region of
the nose bridge, and the two longitudinal end regions of the adhesive substance
layer 3 are adhered to opposite side regions of the nose bridge. Restoring
force of theflexible strip 2 bent along the nose bridge lifts the opposite
side regions of the nose bridge to which the two longitudinal end regions of
theadhesive substance layer 3 are adhered. Thus, the nasal cavity is expanded
so as to relieve nasal blockage.
The
longitudinal middle region of therelease liner 4, i.e., the second piece 4b of
therelease liner 4, abuts the top region of the nose bridge so that the
adhesive substance layer 3 does not adhere to the top region of the nose
bridge. Therefore, theadhesive substance layer 3 does not peel skin of the top
region of the nose bridge and the top region of the nose bridge is not damaged
when thenasal dilator 1 is removed from the nose bridge.
The
