BOTTLE CAP
Disclosed is a bottle cap configured to open and close a mouth of a bottle. The bottle cap is easily may be easily removed with only small force. When the bottle cap is fixed to fit a twisting groove formed at the bottle cap on an edge or corner of a supporting object such as a table and a bottle is rotated in such a way that great force is applied to the bottle cap, even a person who has a weak grip may easily remove the bottle cap with a relatively smaller force than that used with a general bottle cap. Also, the bottle cap further includes a sound generator to notify that the bottle cap has been removed by generating a sound when removing is performed at a blind spot.
This application claims priority to and the benefit of Korean Patent Application No. 10-2015-0184852, filed on Dec. 23, 2015, the disclosure of which is incorporated herein by reference in its entirety.
BACKGROUND1. Field of the Invention
The present invention relates to a bottle cap configured to open and close the mouth of bottle, and more particularly, to a bottle cap capable of being easily removed with only small force.
2. Discussion of Related Art
Generally, in the case of a bottle with a bottle cap that is formed of polyethylene terephthalate (PET), glass, iron, or aluminum, the bottle cap is strongly fastened to the bottle and is rotated to be separated from a bottle coupling portion when separating the bottle cap from the bottle coupling portion.
A general bottle cap includes a plurality of protrusions or grooves formed at an outer circumferential surface of the bottle cap in a longitudinal direction to increase frictional force to be easily separated from a bottle coupling portion, thereby easily removing the bottle cap.
However, although adult men have no great difficulty in removing bottle caps, children, women, or the old who are weak have difficulty removing bottle caps. When removing a bottle cap of a bottle filled with viscous materials, since it is not easy even for adults who have enough strength to remove the bottle cap, they remove the bottle cap while covering the same with rubber or a towel.

SUMMARY OF THE INVENTIONAn aspect of the present invention provides a screw-coupling type bottle cap in which a twisting groove for removal is formed and a bottle having a volume greater than the bottle cap is rotated while being gripped to apply greater force to the bottle cap, thereby easily removing the bottle cap.
According to an aspect of the present invention, there is provided a bottle cap coupled to a bottle to open and close the bottle. The bottle cap includes a coupling portion including an opening formed at a bottom end thereof to enable a first fastening portion in a screw shape formed at a top of the bottle to be inserted thereinto and a second fastening portion formed therein in a screw shape to correspond to the first fastening portion to be screw-coupled with the first fastening portion, and a twisting portion configured to extend upward from the coupling portion and include a twisting groove recessed downward from a top surface thereof at a top thereof.
The twisting groove may have a triangular cross section.
The twisting groove may have a hemispherical or curved cross section.
The twisting groove may have a tetrahedral cross section.
An uneven portion may be formed at a surface of the twisting groove.
The twisting groove may further include an elastic pad at the surface thereof.
The bottle cap may further include an auxiliary coupling portion configured to extend below the coupling portion and include an insertion grove to enable another bottle cap to be inserted thereinto. Here, a plurality of holding protrusions configured to extend upward and be spaced apart from each other in a circumferential direction may be formed at the insertion groove of the auxiliary coupling portion. Also, holding grooves configured to extend upward and downward and be spaced apart from each other in the circumferential direction to correspond to the holding grooves may be formed at outer circumferential surfaces of the coupling portion and the twisting portion.
The bottle cap may further include a sound generator installed at a top of an inside of the coupling portion for notifying whether the bottle cap has been removed. Here, the sound generator may be installed to be in close contact with a top surface of the inside of the coupling portion, have elasticity, and include a flow channel formed along an edge to enable air to be suctioned through a gap from the top surface of the inside of the coupling portion and a connecting groove connected to the flow channel at one side thereof.
The coupling portion and the twisting portion may be formed to be mutually couplable and separable. The twisting portion may include an insertion groove therein to enable the coupling portion to be inserted thereinto. A plurality of holding protrusions configured to extend upward and downward and be spaced apart from each other in a circumferential direction may be formed at an outer circumferential surface of the coupling portion. A plurality of holding grooves configured to extend upward and downward in the circumferential surface to correspond to the holding protrusions may be formed at an inner circumferential surface of the twisting portion.
The above and other objects, features and advantages of the present invention will become more apparent to those of ordinary skill in the art by describing exemplary embodiments thereof in detail with reference to the accompanying drawings, in which:
Hereinafter, a bottle cap according to exemplary embodiments of the present invention will be described with reference to the attached drawings.
The coupling portion 10, as shown in
The twisting portion 20, as shown in
The twisting groove 21, as shown in
Meanwhile, a bottle cap 102 according to another embodiment of the present may be formed in a structure, as shown in
Meanwhile, a bottle cap 103 according to still another embodiment of the present may be formed in a structure, as shown in
Also, a bottle cap 104 according to another embodiment of the present may be formed in a structure, as shown in
In the cases shown in
Also, a bottle cap 105 according to another embodiment of the present may be formed in a structure, as shown in
Meanwhile, the twisting portion 20 with an uneven portion formed at a surface of the twisting groove 21 to increase frictional force at the corner 90a of the supporting object 90 may be applied to bottle caps 106, 107, and 108 according to other embodiments of the present invention, as shown in
The uneven portion may include a plurality of friction protrusions and a plurality of friction grooves configured to extend in a longitudinal direction of the twisting groove 21 and be spaced at regular intervals, as shown in
The uneven portion may include friction protrusions 31 and friction grooves 32 repeatedly formed in a sinusoidal shape, as shown in
Meanwhile, the uneven portion may include a plurality of friction protrusions 35 configured to protrude outwardly from the surface of the twisting groove 21 in a hemispherical structure and be spaced apart from each other, as shown in
Also, a bottle cap 109 according to another embodiment of the present invention, as shown in
Also, a bottle cap 110 according to another embodiment of the present invention may further include an auxiliary coupling portion 50 for coupling with a general bottle cap or the other bottle caps 101 to 109 according to the embodiments of the present invention.
Referring to
As shown in the drawing, when another bottle cap is coupled to the auxiliary coupling portion 50 of the bottle cap 110, the holding protrusions 52 are inserted into and engaged with the holding grooves. When the auxiliary coupling portion 50 is rotated, the other bottle cap coupled therebelow may be rotated.
Also, a bottle cap 111 according to another embodiment of the present invention may further include a sound generator 60.
Referring to
In a state in which the bottle cap 101 is coupled to the bottle B, the sound generator 60 is pressurized by a top end of the bottle B and comes into close contact with the top surface of the inside of the coupling portion 10 while a top surface thereof and the flow channel 61 are compressed. However, when the bottle cap 101 is removed, since air passes through the narrow connecting groove 62 or the lid and enters the flow channel 61, a sound is generated.
Also, in a bottle cap 112 according to another embodiment of the present invention, the coupling portion 10 including the second fastening portion and the twisting portion 20 including the twisting groove 21 may be formed to be couplable with and separable from each other.
Referring to
