Description
TECHNICAL FIELD
[0001] The present invention relates to a side-pressure type safety
cap, and in particular to a side-pressure type safety cap which is
configured for a cap to be opened and closed only when an engaging
protrusion and a rotating protrusion come into contact with each
other by a side pressure of an outer cap, so a kid is prevented
from eating a harmful substance to a human body by preventing a
kid, who does not know what is in the container, from opening the
cap, so unnecessary consumption of the contents stored in the
container can be prevented.
BACKGROUND ART
[0002] A cap is generally designed to prevent the contents stored
in a container body from discharging to the outside as it is capped
at the top of the container body while preventing contamination of
contents.
[0003] The above mentioned cap is so designed that anyone can
easily open and close as it rotates on one or the other direction
because it is screwed to the threads of a container body. With this
construction, a kid who lacks discernment may open easily the cap
thus spilling the contents, which results in over consumption of
the contents. In particular, in case that the container body stores
contents harmful to a human body, a kid may drink the contents
without knowing what is in the container body, so a serious
accident may happen.
[0004] In order to improve the above mentioned problems, there are
provided a structure featuring in that the cap can be opened only
when the top of the cap is pressed downward, and a structure
featuring in that the cap can be opened only when both sides of the
cap are pressurized for the kid not to easily open the cap.
[0005] The conventional safety cap will be described with reference
to "Bottle assembly preventing children from opening" of the
utility model registration number 0318864. The above mentioned
utility model registration of the safety cap is characterized in
that there is provided a container assembly formed of a hollow
container body part of the top of which is open, and a cap 20
covering the opening of the container body. The container body 10
comprises a neck 14 extending with a diameter smaller than the
other portions of the container, an outlet 11 formed as the top of
the neck 14 is open, a male engaging screw 12 protruded from the
surrounding of the neck 14, a flange 13 extending along the
surrounding of the neck 4 as much as a certain width in an outer
radial direction, and an engaging protrusion 15 protruded from the
top of the flange 13. The cap 20 comprises an upper side engaging
protrusion 25 formed at the inner wall surface while corresponding
to the engaging protrusion 15, an inner cap 23 with the inner
diameter matching the outer diameter of the outlet 11, and a female
engaging screw 22 protruding from the inner wall surface of the
inner cap 23 while corresponding to the male engaging screw 12.
[0006] The conventional safety cap 20 forms a flange 13 at the
container body 10 so as to form an engaging protrusion 15 butting
with the upper side engaging protrusion 5 formed in the interior of
the cap 20 when opening the cap 20, and the engaging protrusion 15
formed at the top of the flange 13, so the construction of the
container body 10 seems complicated, which makes it impossible to
obtain the role of the safety cap when engaging the cap 20 to
various containers with only threads.
DISCLOSURE OF INVENTION
[0007] Accordingly, the present invention is made to improve the
above mentioned problems encountered in the conventional art and
other problems. It is an object of the present invention to provide
a side pressure type safety cap which is configured for a cap to be
opened and closed only when an engaging protrusion and a rotating
protrusion come into contact with each other by a side pressure of
an outer cap, so a kid is prevented from eating a harmful substance
to a human body by preventing a kid, who does not know what is in
the container, from opening the cap, so unnecessary consumption of
the contents stored in the container can be prevented.
[0008] When the cap rotates as the engaging protrusion of the inner
cap the rotating protrusion of the outer cap are engaged and
rotate, the threads formed at the inner surface of the inner cap
are thread-engaged with the threads of the container body, so the
cap can be opened and closed. The above mentioned construction can
be well applied to all the containers with threads.
[0009] To achieve the above objects, there is provided a side press
type safety cap in a safety cap which is thread engaged onto the
top of a container body which stores contents, for thereby opening
and closing an outlet of the container; an inner cap which has
threads at its inner surface for surrounding and thread-engaging
the top of the container body, a plurality of regularly spaced
engaging protrusions formed at its outer surface and surrounding
the same; an outer cap which surrounds and engages the inner cap
and has a rotating protrusion which protrudes from between the
plurality of the engaging protrusions at each side of the inner
surface and is engaged with the engaging protrusion and rotates the
inner cap.
[0010] In addition, the engaging protrusion comprises an engaging
protrusion portion protruded forward from the outer surface of the
inner cap; and a bent part which is bent in one direction from an
end portion of a protrusion piece.
[0011] In addition, the bent part comprises a slope surface which
is gently in the direction of the end portion, going farther from
an outer surface of the inner cap.
[0012] In addition, at the rotating protrusion is formed a mounting
groove for mounting the front end of the engaging protrusion
therein.
[0013] In addition, at the outer cap is formed a press indication
part indicating a pressed portion in the outer surface facing the
rotation protrusion for a user to rotate the outer cap while
pressing the same.
ADVANTAGEOUS EFFECTS
[0014] As described above, the present invention has an advantages
in that a cap is configured to be opened and closed only when an
engaging protrusion and a rotating protrusion come into contact
with each other by a side pressure of an outer cap, so a kid is
prevented from eating a harmful substance to a human body by
preventing a kid, who does not know what is in the container, from
opening the cap, so unnecessary consumption of the contents stored
in the container can be prevented.
[0015] In addition, the present invention has an advantage in that
when the cap rotates as the engaging protrusion of the inner cap
the rotating protrusion of the outer cap are engaged and rotate,
the threads formed at the inner surface of the inner cap are
thread-engaged with the threads of the container body, so the cap
can be opened and closed. The above mentioned construction can be
well applied to all the containers with threads.

BEST MODES FOR CARRYING OUT THE INVENTION
[0020] The present invention will be described with reference to
the accompanying drawings. It is noted that the same reference
numerals appearing in each drawing means the same elements.
[0021] FIG. 1 is a disassembled perspective view illustrating a
construction of a side pressure type safety cap according to a
preferred embodiment of the present invention. FIG. 2 is an engaged
cross sectional view illustrating a construction of a side pressure
type safety cap according to a preferred embodiment of the present
invention. FIG. 3 is a cross sectional view illustrating a press
indication part of a side pressure type safety cap according to a
preferred embodiment of the present invention.
[0022] FIGS. 4 and 5 are views illustrating an opening and closing
state on the basis of an engagement of an inner cap and an outer
cap of a side pressure type safety cap according to a preferred
embodiment of the present invention.
[0023] As shown in FIGS. 1 to 5, the side pressure type safety cap
according to a preferred embodiment of the present invention
comprises an inner cap 100 and an outer cap 200.
[0024] The inner cap 100 is thread engaged to the thread 11 formed
at the top of the container body 10 configured to store contents
and has a thread 110 formed at its inner surface for the thread
engagement with the thread 11.
[0025] In the present invention, a plurality of regularly spaced
engaging protrusions 120 are formed along the outer surface of the
inner cap 100. The engaging protrusion 120 comprises a protrusion
piece 121 protruding forward from the outer surface of the inner
cap 100, and a bent part 122 bent in one direction at the end of
the inner cap 100.
[0026] The engaging protrusion 120 is formed in an inverted
L-shaped and consists of a protrusion piece 121 and a bent part
122. During the rotation of the outer cap 200, the front end 120a
and the terminal part 120b of the engaging protrusion 120 are
engaged with the rotation protrusion 210 for thereby opening and
closing the safety cap.
[0027] Meanwhile, the bent part 122 has a slope surface which
becomes gentle in the direction of the end portion, going farther
from the outer surface of the inner cap 100. When it is intended to
close the safety cap by rotating the outer cap 200, the rotation
protrusion 210 is engaged with the terminal part 120b of the
engaging protrusion 120, so the inner cap 100 can rotate
together.
[0028] The outer cap 200 allows the inner cap 100 to rotate in
engagement with the engaging protrusion 120 depending on the
rotations while the outer cap 200 is engaged with the inner cap 100
while surrounding the same. In the present invention, at each side
of the inner surface of the outer cap 200 is provided a rotation
protrusion 210 protruding between the engaging protrusion 120.
[0029] One surface of the rotation protrusion 210 is formed of a
gentle slope, the other surface having a sharp slope of about
90.degree., so the rotation protrusion 210 is engaged with either
the front end 120a or the terminal part 120b of the engaging
protrusion 120 depending on the rotations one direction or the
other direction of the outer cap 200.
[0030] At the rotation protrusion 210 is formed a mounting groove
211 for the front end 120a of the engaging protrusion 120 to mounts
therein. When rotating the outer cap 200 by pressing each side of
the same, the front part 120a of the engaging protrusion 120 is
mounted in the mounting groove 211, and the inner cap 100 comes to
rotate together with the outer cap 200, so the safety cap can be
opened.
[0031] At the outer cap 200 is formed a press indication part 220
indicating a pressed portion in the outer surface facing the
rotation protrusion 210 for a user to rotate the outer cap 200
while pressing the same.
[0032] Referring to FIGS. 4 and 5, the opening and closing
operations of the side press type safety cap according to a
preferred embodiment of the present invention will be
described.
[0033] FIGS. 4 and 5 are views illustrating an opening and closing
state on the basis of an engagement of an inner cap and an outer
cap of a side pressure type safety cap according to a preferred
embodiment of the present invention.
[0034] As shown in FIG. 4, when it needs to close the side press
type safety cap according to a preferred embodiment of the present
invention, holding the outer cap 200 the user rotates the outer cap
200 in the closing direction. When the rotation of the outer cap
200 is finished, the rotation protrusion 210 protruded from each
side of the inner surface of the outer cap 200 rotates together. As
the rotation protrusion 210 rotates, the other surface which
corresponds to a sharp slope of the rotation protrusion 210 becomes
engaged with the terminal part 120b of the engaging protrusion 120
and allows the inner cap 100 to rotate. Therefore, the user can
close the cap in the same way as closing the common thread type cap
onto the container body.
[0035] As shown in FIG. 5, when it needs to open the side press
type safety cap according to a preferred embodiment of the present
invention, the user rotates the outer cap 200 in the opening
direction in a state that the press indication part 220 of the
outer cap 200 is pressed. When the press indication part 220 is
pressed, each side of the outer cal 200 where the rotation
protrusion 210 is formed is dented a little. When the outer cap 200
is rotated in the opening direction, the rotating protrusion 210 of
the outer cap 200 is engaged with the front end 120a of the
engaging protrusion 120, so the inner cap 100 can rotate together,
thus opening the safety cap.
[0036] When the outer cap 200 is rotated in a state that the press
indication part 220 is no pressed when opening the safety cap, the
engaging protrusion 120 and the rotating protrusion 210 idle rotate
thanks to the space between the engaging protrusion 120 and the
rotating protrusion 210. Therefore, the inner cap 100 does not
rotate, and the safety cap does not open.
[0037] As the present invention may be embodied in several forms
without departing from the spirit or essential characteristics
thereof, it should also be understood that the above-described
examples are not limited by any of the details of the foregoing
description, unless otherwise specified, but rather should be
construed broadly within its spirit and scope as defined in the
appended claims, and therefore all changes and modifications that
fall within the meets and bounds of the claims, or equivalences of
such meets and bounds are therefore intended to be embraced by the
appended claims.
