[TITLE OF THE INVENTION]
SPOUT FITTING APPARATUS AND CONTAINER
[TECHNICAL FIELD OF THE INVENTION]
[0001]
The present invention relates to a spout fitting apparatus and a
container having its spout shaped like a spout fitting apparatus, especially
for a
spout fitting apparatus can be easily attached to a container, such as a
plastic
bottle and a bottle.
[BACKGROUND OF THE INVENTION]
[0002]
When pouring out the fluid from a container, such as a plastic bottle, a
bottle or a can, the inside of the container becomes negative pressure since
the
spout of the container is stuffed up with the fluid because of the width of
the spout
and the viscosity of the fluid itself, when the fluid pours and flows out from
the
container. For the above-mentioned reason, once the outflow of the fluid
stops, the
container inhales the air of the same volume as the discharged fluid from the
container. Because such a phenomenon occurs repeatedly, the fluid flows out
from
the container little by little. This phenomenon is called a "Hiccup
phenomenon".
When "Hiccup phenomenon" occurs, it takes much time to pour the fluid from the
container and also the fluid flowing out from the container scatters and
bounds. It
may cause to spoil surrounding area of the container.
In order to solve the above-mentioned problems, Japan patent
publication number "JP2005-41570" (hereafter called Patent document 1)
discloses
that the method of securing the airflow path by inserting a straw into an
instrument, which can hold the straw, attached on the spout of a plastic
bottle or a
bottle.

Further, Japan patent publica.tion number "JP2002-249138" (hereafter
called Patent document 2) discloses that an attachment attached on the inside
of
the spout or neck of the spout of a bottle is fitted to a pipe connecting the
air trap
and the part within a 3 cm radius around a spout of a plastic bottle or a
glass
bottle.

[BEST MODE OF CARRYING OUT THE INVENTION]
[0012]
The present invention will be explained hereunder in detail based upon
examples with reference to the accompanying drawings.
Fig. 1 shows a schematic perspective view of the present invention
"Spout fitting apparatus" and Fig. 2 shows a schematic perspective view of the
present invention "Spout fitting apparatus" attached with the spout of the
container, such as a plastic bottle and a bottle, pouring out the fluid from
the spout.
As shown in Figs. 1 and Fig. 2, a spout fitting apparatus 10 in the
present invention consists of locking portion 1, falling-prevention stopper 2,
partition wall 3 and air inflow conduit 4. The container 20, which is usually
known
as a plastic bottle or a bottle, consists of spout 21 and shoulder 22.
5
CA 02600354 2007-09-06
[0013]
In the present invention, the locking portion 1 of the spout fitting
apparatus 10 comprises a tubular type of vertical division so that it can
insert in
the spout 21 of the container 20 and has the elastic force to the direction
that
extends to the inner wall of the spout 21. Therefore, the spout fitting
apparatus
can be easily attached with various sizes of the spout of containers. The
locking
portion 1 of the spout fitting apparatus 10 adheres to the inner wall of the
spout 21
of the container 20 at least more than semicircle of the spout 21 when the
locking
portion 1 is inserted in the spout 21 of the container 20.
The fallingprevention stopper 2 is provided at the upper edge of the
locking portion 1. When the looking portion 1 is inserted in the spout 21 of
the
container 20, the falling-prevention stopper 2 is hooked up with the upper
edge of
the spout 21 so that the spout fitting apparatus does not fall into the
container 20.
[0014]
The partition wall 3 is formed in the locking portion 1 in order to
separate the outflow path of the fluid from the inside of the container 20 and
the
inflow path of the air from the outside of the container 20 and the air inflow
conduit 4 is extended inside the container 20 from the air inflow side. The
air
inflow conduit 4 curves along the inclination of the inside of the container
20, and
the head of the air inflow conduit 4 extends to the shoulder part of the
container 20.
The opening of the head of the air inflow conduit 4 is cut crosswise in order
to face
to the inner wall of the container 20 so that inflowing of the air from the
outside to
the shoulder 22 is performed easily. Since the partition wall 3 does have the
predetermined curvature against the locking portion 1, it does not become an
obstacle by bending easily even if the diameter of the spout 21 of the
container 20
is small.
[0015]
If the direction to which the spout fitting apparatus 10 attached is
6
CA 02600354 2007-09-06
turned upward and the fluid inside of the container 20 is poured out, when the
spout fitting apparatus 10 is inserted in the spout 21 of the container 20 and
the
locking portion 1 is attached with the upper edge of the spout 21, the air
comes into
the inside of the container 20 through the air inflow conduit 4 from the air
inflow
path located at the upper side of the partition wall 3 and the fluid inside of
the
container comes out continuously through the lower side of the partition wall
3.
Therefore, the flow of the fluid is stabilized and the hiccup phenomenon does
not
occur so that the fluid flows out smoothly without scattering around.
[0016]
When the spout fitting apparatus 10 is attached to the container 20,
most part of the spout fitting apparatus 10 is stored in the container 20
except for
the slight part of falling-prevention stopper 2 because of its thickness.
Therefore,
after attaching the spout fitting apparatus 10 with the spout 21, it does not
become
obstructive and the original cap is used as it is.
[0017]
In the present invention, the spout fitting apparatus can be formed by
thermoplastics, such as polyethylene, polystyrene, and nylon. The locking
portion
1 has elasticity and the spout fitting apparatus has a suitable length.
Therefore, it
can be adapted for change of various diameter of the spout 21, and can use in
common with various containers 20.
[0018]
According to the construction of the present invention "spout fitting
apparatus 10" designed as described in the above, by attaching the spout
fitting
apparatus 10 at the spout 21 of the container20, the flow of the fluid becomes
smoothly without occurring hick-up phenomenon when pouring out the fluid from
the container 20, so that it can prevent from scattering fluid around and it
does not
take much time in order to pour the fluid from the container 20.

CA 02600354 2007-09-06
According to the present invention, the locking portion 1 has elasticity
and the spout fitting apparatus has a suitable length. Therefore, it can be
adapted
for change of various diameter of the spout 21, and can use in common with
various containers 20. And, the falling-prevention stopper 2 is so that the
spout
fitting apparatus does not fall into the container 20. And, most part of the
spout
fitting apparatus 10 is stored in the container 20 except for the slight part
of the
falling-prevention stopper 2 because of its thickness so that it does not
become
obstructive and the original cap is used as it is. Further, the spout fitting
apparatus weights very light and can be manufactured at low cost. Therefore,
there is no substantial burden of the user by attaching the spout fitting
apparatus
with a plastic bottle or a bottle.
[0019]
Although the above explanation was described about the spout fitting
apparatus, if the structure of the spout of the container as same as the spout
fitting
apparatus is formed integrally when manufacturing, the container also has the
same effect as of the spout fitting apparatus. Since the above-mentioned
construction can be manufactured easily by using thermoplastic resin etc. and
a
die. Therefore, it is not expensive considering the structure of the spout
fitting
apparatus and large-scale production will be possible.
[INDUSTRIAL APPLICABILITY]
[0020]
The present invention "Spout fitting apparatus and container" can be
used for a plastic bottle and a bottle containing water, fruit juice, fluid
seasoning,
oil, paint, fluid detergent, and medicine, and can use the container of this
invention by a wide range of industrial fields.
