[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 publication 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.

            [DISCLOSURE OF INVENTION]
[OBJECT OF THE INVENTION]
[0003] However, among the prior art listed above, according to the Patent document 1 which
               discloses an instrument that holds the straw in order to secure the airflow path from
               the inside of the container, there is a deficiency of being easily come off when the
               attached straw begins to pour the fluid from the container.
               And, according to the Patent document 2 which discloses 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, there is a deficiency that an original cap is not able to use as
               a usual tab when the size of the stopper is bigger than that of the spout. Further,
               there is a deficiency that the stopper falls into the container when the size of the
               stopper is smaller than that of the spout.
               The purpose of the present invention is to provide a spout fitting apparatus and a
               container having same construction as a spout fitting apparatus integrally which is
               very easy to attach on the spout of the container such as a plastic bottle or a bottle
               without falling into a container and a consumer can use an original cap of a plastic
               bottle or a bottle as a usual tab, further by attaching the spout fitting apparatus
               at the spout of the container, the flow of the fluid becomes smoothly without occurring
               Hick-up phenomenon when pouring or flowing out the fluid from the container, so that
               it can prevent from scattering fluid around the container.

            [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.
 
            [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 falling-prevention 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 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.
               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
