Description
TECHNICAL FIELD
[0001] The present invention relates to a cap assembly for closing
a container and more particularly to a cap assembly having a
storage chamber for containing a secondary material (ingredient)
for example a concentrated liquid or a granule different from a
material (ingredient) for example water or a beverage accommodated
in a container.
[0002] Such a cap assembly is useful in the various industrial
fields such as medical, phar- maceutical, cosmetic and etc.
BACKGROUND ART
[0003] Generally, when a beverage that requires mixing up a liquid
in a container with a granule or a concentrate liquid as additives
or secondary ingredients such as carbon dioxide, vitamin powder,
etc, it is often necessary that the container has a separate
chamber for storage the secondary ingredients.
[0004] There are many suggestions more than 5,000 including U.S.
Pat. No. 937,049 (filed on Oct. 19, 1909) about the structure for
mixing two or more ingredients in a container.
[0005] However, the containers disclosed in the above patents have
not commercially succeeded because of the problems such as
inefficiency in a manufacture process, inconvenience in use,
etc.
[0006] There are further needs for more easily handling of a cap
assembly and a container for mixing one or more ingredients in an
ingredient contained in a container without problems of changing a
structure or an injury of an elbow caused by acting an excessive
force to open a discharging device for use.
[0007] Recently, PCT/EP2002/004523 filed on Jan. 17, 2002 and
Japanese Patent Application No. 2001-00185428 filed on Jun. 19,
2001 suggested other structure, but a commercial success has not
been obtained.
[0008] Particularly, the structure disclosed in Japanese Patent
Application mentioned above has a problem that a piece cut out from
a discharging port falls into a container and a child may swallow
it. To overcome this problem, a discharging device which is not
separated from a novel neck of a container has been developed, but
such a discharging device could not be used to a conventional neck
of a container.
[0009] A cap having an assembly-typed housing for storage therein
has been known, the assembly-typed housing is limited to the
functions as a storage chamber or simply an sealing means
thereof.
DISCLOSURE OF INVENTION
Technical Problem
[0010] In view of the above, an object of the present invention is
to provide a cap assembly having an improved convenience.
[0011] Another object of the present invention is to provide a cap
assembly which is adapted to open the storage chamber and container
at the same time so that a secondary ingredient may be discharged
and mixed into a primary ingredient in a container.
[0012] Another object of the present invention is to provide a cap
assembly having an integral sealing assembly for obtaining improved
sealing property.
Technical Solution
[0013] In order to accomplish the above-mentioned objects,
according to the present invention, a cap assembly mounted on a
discharging portion of a container for containing a secondary
ingredient different from a primary ingredient in accommodated in a
container, comprises a cap body formed by an upper cap part and a
lower cap part which are adapted to be divided along a cut-off
line; a housing with a storage chamber for a secondary ingredient
formed by the lower portion of the upper cap part; a separate
sealing assembly provided below the lower cap part, comprising a
sealing element and a space through which the secondary ingredient
may be discharged in use; and a mouth formed above the lower cap
part.
BRIEF DESCRIPTION OF THE DRAWINGS
[0014] The above objects, other features and advantages of the
present invention will become more apparent by describing the
preferred embodiments thereof with reference to the accompanying
drawings, in which:
[0015] FIG. 1 is a cross-sectional view of cap assembly in
accordance with a first embodiment of the present invention;
[0016] FIG. 2 is a cross-sectional view of a cap assembly in
accordance with another embodiment of the present invention.
BEST MODE FOR CARRYING OUT THE INVENTION
[0017] Reference will now be made to the drawings to describe the
resent invention in detail. In the following description of the
present invention, the same drawing reference numerals are used for
the same elements even in different drawings, and the duplicate
explanation thereof will be omitted.
[0018] FIG. 1 shows a cap assembly 1 in accordance with the
preferred embodiment of the present invention, which may be mounted
to a container for example a beverage container in such a way of a
conventional thread engagement, a snap-fit engagement or adhering
type.
[0019] The cap assembly 1 in FIG. 1 comprises a cap body 10 and a
sealing assembly 20.
[0020] The cap body 10 comprises an upper cap part 11 and a lower
cap part 12 which are connected by a cut-off line 13, the lower
portion of the upper cap part 11 comprises a housing 14 in which a
chamber 15 for storage of a secondary ingredient is formed.
[0021] The sealing assembly 20 is provided at the lower opening of
the housing 14 having the storage chamber 15 for sealing thereof.
The sealing assembly 20 comprises a sealing element 21 for blocking
the lower opening of the housing 14 and an annular hoop 22 for
connecting the sealing assembly 20 to a connecting portion 16 of
the lower cap part 12.
[0022] At least one opening 23 is formed between the annular hoop
22 and the sealing hoop 21.
[0023] A mouth 24 is formed above the annular hoop 22 and has a
thread 25 for engaging with a thread 17 formed at the inner wall of
the upper cap part 11 of the cap body 10.
[0024] An elongated protrusion 26 is upwardly formed at the sealing
element 21.
[0025] The elongated protrusion 26 may stir the secondary
ingredient in the chamber 15, when a lower end opening of the
housing is opened.
[0026] When the upper cap part 11 is turned in use, the upper cap
part 11 is disconnected along the cut-off line 13 from the lower
cap part and is upwardly moved.
[0027] At this time, the lower portion of the housing 14 is
disconnected from the sealing element 21 and then the secondary
ingredient in the chamber 15 may be discharged into the
container.
[0028] The upper cap part 11 and the lower cap part 12 are easily
disconnected by a cut-off line 13 which is a portion that may be
easily torn and by the thread engagement 17 and 25. However, other
conventional disconnecting structure may be used.
[0029] Preferably, a snap-on-screw-off type structure is used.
[0030] The sealing assembly 20 may be safely retained by the lower
cap part 12.
[0031] The lower cap part 12 may be mounted on the container in
such a manner of a snap fit engagement or a adhering to a paper
pack or a pouch.
[0032] The separate sealing element 21 may be assembled to the
sealing assembly.
[0033] FIG. 2 shows another embodiment of the present invention, in
which the upper cap part 21 and the lower cap part 212 are
separately formed and the mouth 218 is provided above the lower cap
part 212.
[0034] The housing 214 with the storage chamber 215 is formed by
the lower portion of the upper cap part 211.
[0035] When the upper cap part 212 is turned in use, the secondary
ingredient in the storage chamber 215 may be discharged into the
container through the space formed by departing of the sealing
element 21 of the sealing assembly 20 from the housing 214 and is
mixed with the primary ingredient in the container.
[0036] In this embodiment, the elongated protrusion 26 may be
provided at the sealing element 21 and the separate sealing element
21 may be assembled.
[0037] Furthermore, the sealing element 21 may be separated into
the container.
[0038] The lower cap parts 12 and 212 may be fixedly attached to
the container.
INDUSTRIAL APPLICABILITY
[0039] As apparent from the above description, the cap assembly of
the present invention may be adapted to accommodate a concentrate
liquid or a granule to be mixed which a water, a beverage or other
liquid in the container with an easy and improved mixing two
