water. To this end, the user purchases the flavor or vitamin
and the separated bottle water and mixes the flavor or the
vitamin with the bottle water. However, it is very
troublesome for the user to do so.
SUMMARY OF THE INVENTION
Therefore, the present invention has been made in an
effort to solve the above-described problems of the
conventional art. It is an object of the present invention to provide a
cap with a storage chamber for a secondary material that will
be mixed with a primary material contained in a container
associated with the cap by simply opening the cap.
It is another object of the present invention to provide
a product employing such a cap with a storage chamber for a
secondary material.
It is still another object of the present invention to
provide a cap assembly that is simple in a structure, thereby
saving the manufacturing costs.
TECHNICAL SOLUTION
To achieve the above objects, the present invention
provides a cap assembly with a storage chamber including a
stationary member coupled to a container and provided with
a storage chamber defined therein and a movable member with
an operation portion, the movable member being coupled to a
spouting portion of the stationary member to release a
secondary material into the container.

BEST MODE FOR CARRYING OUT THE INVENTION
Preferred embodiments of the present invention will be
described more in detail hereinafter in conjunction with the
accompanying drawings. Wherever possible, the same
reference numerals will be used throughout the drawings to
refer to the same or like parts.
FIGS. 1 and 2 show a first embodiment of the present
invention. A cap assembly 1 includes a stationary member 10
coupled to a neck portion 101 of a container 100 and a movable
member 10 coupled to the stationary member 20.
The stationary member 10 includes a spouting portion 11
extending upward, a storage tube 12 formed extending downward
to store a secondary material A, and a storage space 13 defined
in the storage tube 12.
A seal film 14 is integrally formed on a lower portion
of the storage tube 12, being provided with a cutting line
15.
A fixing portion 16 is formed on a center of the seal
film 14.
The movable member 20 is screw-coupled to a spouting
portion 11 of the stationary member 10. An operation portion
21 is formed extending from an inner center of the movable
member 20.
The operation portion 21 is formed in a tube shape in
which a fixing portion of the seal layer 14 is tightly
inserted.
Therefore, in a state where the secondary material is
filled in the storage tube 12 formed on the stationary member
10, the movable member 20 is screw-coupled to the spouting
portion 11 of the stationary member 10. Then, the
fixingportion 16 formed on the seal layer 14 is tightly
inserted in the operation portion 21 and the stationary member
10 is screw-coupled to the neck portion of the container 100.
At this point, when the movable member 20 is unscrewed
from the spouting portion 11 of the stationary member 10, the
operation portion 21 moves upward together therewith and the
fixing portion coupled on the lower end of the operation
portion 21 also moves upward, thereby moving the seal layer
14 upward.
When the seal layer 14 moves upward above a predetermined
level, the cutting line 15 is broken to separate the fixing
portion 16 from the operation portion 21, thereby defining
an opening. As a result, the secondary material filled in
the storage tube 13 is dropt into the container 100.
Therefore, the secondary material A stored in the
storage space 13 is perfectly protected from humidity by the
seal layer 14. The seal layer 14 is broken when the movable
member 20 is separated to release the secondary material A.
FIG. 3 shows a second embodiment of the present
invention.
A hook step 30 is formed on a lower end of the operation
portion 21 formed on the movable member 20. A fixing portion
16 is formed on the seal layer 14. The fixing portion 16 has
an opened top to which a lower end of the operation portion
21 is inserted. A hook groove 31 in which the hook step 30
is inserted is formed on an inner surface of the fixing portion
16. A cutting line 15 is formed on the seal layer 14 in a
spiral shape.
FIG.4 shows a third embodiment of the present invention.
A lower end of the operation portion 21 is attached on
the seal layer 14 with the cutting line 15. The cutting line
15 is broken when the movable member 20 moves upward.
FIG. 5 shows a fourth embodiment of the present
invention.
A portion of the seal layer 14 is removably assembled
on a lower end of the operation portion 21 formed on the movable
member 20.
That is, an assembling portion 50 provided with a cutting
line 15 is assembled on the seal layer 14,
The assembling portion may be adhered or fitted in the
seal layer 14.
FIG.6 shows a fifth embodiment of the present invention.
An opening 60 is formed on the seal layer 14 and an extreme
end of the operation portion 21 is inserted. A seal seat 61
is attached on the extreme end of the operation portion.
FIG.7 shows a sixth embodiment of the present invention.
A seal layer 14 is integrally formed on a lower portion
of a spouting portion 11 of a stationary member 10. A fixing
portion is formed on the seal layer 14 with a cutting line
15. The fixing portion 16 is inserted in the operation
portion formed in the movable member 20.
INDUSTRIAL APPLICABILITY As described above, the present invention can be
associated with a variety of containers such as a PET bottle
and a pouch container.
