Description

STOPPER AND CONTAINER HAVING THE SAME
The present invention relates to a stopper and a container having the same, particularly a stopper that makes it possible to discharge a desired amount of liquid substance by removing slosh generated when the liquid substance is discharged out of a container.
In general, the opening of containers storing liquid substance, such as sesame oil or edible oil is covered with a stopper.
A discharge hole for discharging the liquid substance in the container is formed through the stopper, such that the liquid substance is discharged out through the hole when a user tilts the container.
In this case, the external air flows into the container by a pressure difference between the outside and the inside of the container, and accordingly, slosh occurs.
As described above, slosh is generated by repetitive discharge of the substance and inflow of the external air through one discharge hole, and accordingly, it is difficult to not only quickly discharge the substance, but pour a desired amount of substance, because bubbles are produced in the container by the inflow of the air.
The present invention has been made in an effort to provide a stopper that makes it possible to discharge a predetermined amount of liquid substance by removing slosh that occurs when discharging the liquid substance from a container, and a container having the stopper.
Further the present invention has been made in an effort to provide a stopper of which an outer cap and an inner cap can be easily assembled and that prevents a liquid substance from leaking, and a container having the stopper.
An embodiment of the present invention provides a stopper including: an outer cap having an upper surface with a discharge hole and a side extending downward from the outer edge of the upper surface; and an inner cap having a cylindrical body and a protrusion and combined with the outer cap, in which the protrusion has an inclined surface extending upward from the lower edge of the body toward the center and a plurality of inlet/outlet holes formed around the inclined surface.

Advantages and features of the present invention and methods to achieve them will be clear from exemplary embodiments described below in detail with reference to the accompanying drawings. However, the present invention is not limited to exemplary embodiments described herein and will be implemented in various forms. The exemplary embodiments are provided by way of example only so that a person of ordinary skill in the art can fully understand the disclosures of the present invention and the scope of the present invention. Therefore, the present invention will be defined only by the scope of the appended claims. Like reference numerals designate like components throughout the specification.
Hereinafter, the present invention is described with reference to the drawings for illustrating a stopper and a container having the stopper according to embodiments of the present invention.
FIG. 1 is an exploded perspective view showing a stopper according to a preferred embodiment of the present invention and a container having the stopper.
A stopper according to a preferred embodiment of the present invention includes an outer cap 10 and an inner cap 20 combined with the outer cap 10 and container having the stopper further includes a container body 30, in addition to the outer cap 10 and the inner cap 20.
FIG. 2A is a top view of an outer cap according to a preferred embodiment of the present invention and FIG. 2B is a cross-sectional view taken along the line A-A in FIG. 2A.
Referring to FIGS. 2A and 2B, the outer cap 10 has a side 11 and an upper surface 12.
The upper surface 12 is the portion forming the top of the outer cap 10 and a discharge hole 13 for discharging a liquid substance is formed through the upper surface 12.
The discharge hole 13, as shown in FIG. 2A, is preferably formed at the center of the upper surface 12, and is covered later by a cutting cap 40.
The side 11 is the portion forming the outer side of the outer cap 10 and extends downward from the outer side of the upper surface 12.
An opening 31 where the outer cap 10 is combined is usually formed in a circular shape and the side 11 is also preferably formed in a circular shape to be combined with the opening 31.
The outer cap 10 may further has a discharge guide 18 that extends upward from the upper surface 12, around the discharge hole 13, in order to allow the liquid substance discharged through the discharge hole 13 to stably flow to the outside.
FIG. 3A is a top view of an inner cap according to a preferred embodiment of the present invention and FIG. 2B is a cross-sectional view taken along the line B-B in FIG. 3A and an enlarged view showing the main parts.
Referring to FIGS. 3A and 3B, the inner cap 20 is disposed inside the outer cap 10 and has a body 21 and a protrusion 23.
The body 21 has a cylindrical shape and forms the body of the inner cap 20.
The protrusion 23 has an inclined surface 200 and inlet/outlet hole 210 and the inclined surface 200 extends upward toward the center from the lower edge of the body 21.
A plurality of inlet/outlet holes 201 is formed around the inclined surface 200. Although five inlet/outlet holes 201 are formed in a triangular shape in FIGS. 3A and 3B, the shape may be modified in various ways and the number inlet/outlet holes may be modified in various ways in accordance with the size of the protrusion 23.
Substantially, the protrusion 23 is formed in a conical shape with the top removed, and the top-cut portion 210 is closed, as shown in the figures, such that it prevents the liquid substance from being poured and discharged, when the liquid substance is discharged, with the container tilted.
According to the stopper according to a preferred embodiment of the present invention, since the inlet/outlet holes 201 are formed at the inner cap 20, the liquid substance is discharged through the inlet/outlet hole 201 at the lower portion when the substance is discharged, and the external air flows into the container through the inlet/outlet holes 210 at the upper portion, such that slosh of the substance does not occur, and accordingly, the substance can be smoothly discharged and a desired amount of substance can be discharged.
Further, since the protrusion 23 is formed not in a flat surface, but a conical shape with the top cut (cone), the inlet/outlet holes 201 can be more widely formed along the inclined surface and the external air can more smoothly flow inside.
FIG. 4 is a cross-sectional view showing when the outer cap and the inner cap according to a preferred embodiment of the present invention are assembled.
In the stopper according to a preferred embodiment of the present invention, the outer cap 10 further has a first locking step 101.
