Description
BACKGROUND
[0001] 1. Field of the Invention
[0002] The invention relates to a stopper assembly, and more
particularly, to an improved stopper to prevent a sloshing of an
liquefied content when a bottle is tilted, to allow a predetermined
amount of the content to be poured and to allow the content to be
easily discharged.
[0003] 2. Description of the Related Art
[0004] Generally, in a bottle in which a space accommodating a
content is lengthily in a length direction and have a narrow inlet,
the inlet thereof is designed to be openable and closeable by a cap
member. In particular, the cap member includes an outer cap 3
openly and closely coupled to the inlet of the bottle 1 to seal the
coupled inlet, an inner cap 2 forming a small hole 2a for
preventing a liquefied content from being discharged in large as
shown in FIGS. 1 and 2. However, a outside air enters an inner part
of the bottle 1 through the small hole 2a because a vacuum in the
inner space a of the bottle become larger than that in an outside
space, that is, a vacuum pressure of the inner space of the bottle
become larger than an atmospheric pressure.
[0005] That is, when the inner space a of the bottle becomes the
same atmospheric pressure as the outside space b, it is possible to
discharge the content of the bottle, and thus a volume of the inner
space increases by the discharged amount to be a vacuum pressure,
so that an operation moving air from the outer space b is
repeatedly occurs.
[0006] Therefore, the content can not be discharged quickly due to
a repetitive operation of discharge of the content and an inflow of
the outside air through one a small hole 2a and pouring the content
quantitatively is obstructed due to a air bubble being produced
within the bottle.
[0007] Even though the bottle is tilted to discharge the content, a
residual content remains between the inner cap 2 and the bottle
1.
[0008] In order to discharge the residual content, it is
disadvantage that the inner cap 2 should be separated.

present embodiment of the present invention, the stopper assembly
includes an inner cap 20 coupled to an exiting port of the bottle
10 and an outer cap 30 openablely and closablely coupled to an
outer side of the inner cap 20 to seal an inlet of the bottle. A
male screw is formed at an outer peripheral surface of the inlet of
the bottle 10 and a female screw threaded with the male screw is
formed at the inner peripheral surface of the outer cap 30.
[0024] Referring to FIGS. 4 and 6, the inner cap 20 includes a
cylindrical body 21 coupled to the inlet of the bottle 10 and a
slope 22a extending to the upper side thereof toward the center
thereof from an edge of a lower end section of the body 21 and a
protrusion 22 forming a plurality exit holes 22b is around the
slope 22a.
[0025] Substantially, the protrusion 22 is in a truncated conical
shape, wherein the truncated section 22d is closed as shown to
prevent a phenomenon in which the content of the bottle is poured
to be discharged when the bottle is tilted to discharge the
content.
[0026] The exit hole 22b is lengthily formed from the lower end
section of the slope 22a to the upper end section thereof and a
protrusion 22c protruding from the edge of the lower end section of
the inlet hole 22b is formed. The protrusion 22c is formed at every
exit hole 22b.
[0027] In addition, the inner cap 20 is made of a synthetic resin
capable of an elastic deformation and the edge of the upper end
section of the body is formed with the outwardly bent elastic piece
21b.
[0028] The inner surface of the outer cap 30 is formed with the
annular sealing rib 31 coupled to the inner peripheral surface of
the upper end section of the body 21 and the circle sealing jaw 32
supporting the elastic piece 21b. That is, the elastic piece 21b is
pressed in between the seal rib 31 and the seal jaw 32 and the

the bottle 10 is tilted to discharge the content.
[0030] In addition, the suspending rib 21a is formed at outer
peripheral surface of the body 21 and supported at the upper end
section of the inlet of the bottle 10 to prevent the inner cap 20
to be excessively approached into the inlet of the bottle.
[0031] In a bottle stopper assembly of the embodiment of the
present invention, when a bottle 10 is tilted to discharge its
liquefied content by forming a plurality of exit holes 22b in an
inner cap 20, the content is discharged through an exit hole
disposed at the lower section thereof and at the same time, air of
the outside flows in the bottle 10 through the exit hole disposed
at the upper section thereof, so that the content is smoothly
discharged without a sloshing of the content, thereby a
predetermined amount of a discharge of content become easily as
shown in FIG. 7.
[0032] It is destroyed that a surface tension of the residual
content 101 between the inner peripheral surfaces bottle 10 and the
edge of the lower end section of the inner cap 20 by forming the
protrusion 22c in the lower end section of the inner cap 20, so
that the residual content 101 is smoothly discharged.
[0033] In addition, the upper end section of the inner cap 20 is
formed with the elastic piece 21b and the outer cap 30 is formed
with the sealing rib 31 and the sealing jaw 32 to provide an
improved reliability of the sealing.
[0034] In addition, the inner peripheral surface of the inlet of
the bottle 10 is formed with the concave groove 11 and the inner
cap 20 is formed with the convex section 21c to prevent the inner
cap 20 from being deviated from the bottle 10 when the bottle is
tilted to discharge the content.
[0035] A stopper assembly of the present invention is to prevent a
sloshing of a liquefied content when a bottle is tilted to allow a
predetermined amount of the content to be poured and to allow the
content to be easily discharged.
[0036] In a stopper assembly of the present invention, when a
bottle is tilted to discharge its liquefied content by forming a
plurality of an exiting hole in an inner cap, the content is
discharged through an outlet hole disposed at the outlet thereof
and at the same time, air of the outside disposed at the upper
section thereof flows in the bottle through the exiting hole
disposed the upper section thereof, so that the discharge of the
content is smoothly discharged without a sloshing of the content,
thereby a predetermined amount of a content is discharged easy.
[0037] Furthermore, it is destroyed that surface tension of the
content remained between the edge of the lower end section of the
inner cap and the inner peripheral surface of the bottle by forming
a protrusion in a lower end section of the inner cap to allow a
smooth discharge of the residual content.
[0038] In addition, the upper end section of the inner cap is
formed with the elastic piece and the outer cap to improve the
reliability of the seal is formed with the sealing rib and the
sealing jaw.
[0039] When the bottle is tilted to discharge the content under the
condition that the inner peripheral surface of the inlet of the
bottle is formed with the concave groove is the inner cap is formed
with and the convex section, a combined state of the inner cap
keeps stable.
