Best Mode for Carrying out the Invention

[33] The present invention provides an anti-fake bottle cap connected to a cylindrical bottle including a discharge port formed on the top thereof, through which a substance contained in the bottle discharged, a fastening member having screw threads and formed on an outer circumference of the discharge port, and constraint projections bisymmetrically formed on the outer circumferential surface of the discharge port, the anti-fake bottle cap comprising: an inner cap, connected and fixed to the fastening member formed on the top of the bottle, formed in a cylindrical shape, and including a cylindrical cutting member formed in the middle of the top thereof to push upward an anti-fake cut portion to be opened, a plurality of connecting projections formed on an outer circumference thereof and spaced at regular intervals, a plurality of inner cap engaging projections formed in a circular shape on a top surface thereof, a fastening member connected to the fastening member of the bottle, and a plurality of stopping projections formed on a top surface of the fastening member; and an outer cap, connected to the connecting projections of the inner cap, formed in a cylindrical shape, and including the anti-fake cut portion formed in the middle of the top thereof, a guide projection formed on an inner circumferential surface thereof to guide the inner cap when the inner cap is connected, a stepped portion formed at the bottom of the guide projection, a support projection formed at the bottom of the stepped portion, a plurality of outer cap engaging projections formed on a ceiling surface and engaged with the inner cap engaging projections, and a plurality of elastic pieces formed to project downward and arranged on the outside of the outer cap engaging projections. Mode for the Invention

[34] Hereinafter, the present invention will now be described in more detail with reference to the accompanying drawings.

[35] Referring to FIGS. 1 to 6, an anti-fake bottle cap 100 of the present invention includes an inner cap 104 connected to the top of a bottle 102 containing a liquid substance and an outer cap 106 connected to the top of the inner cap 104 to prevent the inner cap 104 from being opened independently and including an anti-fake cut portion 36 through which a user can determine whether the substance is quantitatively contained in the bottle 102 and whether the bottle 102 has been opened by a stranger.

[36] A discharge port 14 is formed to project upward on the top of a body 10 of the bottle

102, and a fastening member 12 having a plurality of male threads is formed on the outer circumferential surface of the discharge port 14.

[37] Moreover, a constraint projection 16 is formed on the outer circumference of the top of the fastening member 12.

[38] The constraint projection 16 has a right triangular cross-section and is connected to the inner cap 104. The constraint projection 16 allows the user to apply more than a predetermined force when he or she rotates the inner cap 104 to open the bottle cap 100.

[39] As shown in 1, 3, and 4, the inner cap 104 is inserted and connected to the fastening member 12 of the bottle body 10.

[40] At this time, since the inner cap 104 is connected to the fastening member 12 of the bottle body 10, the inner cap 104 is not opened even if the outer cap 106 is rotated in the initial state.

[41] The inner cap 104 includes a cylindrical inner cap body 18 and a cylindrical cutting member 20 formed to project upward on the inner cap body 18.

[42] The cutting member 20 cuts the anti-fake cut portion 36 of the outer cap 106, which will be described later.

[43] The cutting member 20 has a cylindrical shape in which the middle portion is concave and the outer circumferential edge is sharpened to facilitate the cutting operation.

[44] Here, a plurality of rectangular inner cap engaging projections 22 are formed to project upward on the outer top surface of the cutting member 20. [45] A polygonal connecting projection 24 is formed to project outwardly on the upper outer circumference of the inner cap body 18. [46] A plurality of connecting projections 24 are formed to be connected to connecting members 42 of an outer cap body 32 which will be described later. [47] A fastening member 26 connected to the fastening member 12 of the bottle body 10 is formed on the inner side of the inner cap body 18. [48] A connecting portion 28 is formed in the middle of the ceiling surface of the inner cap body 18 such that the discharge port 14 of the bottle body 10 is connected thereto. [49] A plurality of right triangular stopping projections 30 are formed to be spaced apart from one another at regular intervals on the upper inner circumference of the fastening member 26 formed on the inner cap body 18. [50] The stopping projections 30 are in contact with the constraint projections 16 formed at the top of the fastening member 12 and are rotated when more than a predetermined force is applied. [51] The outer cap 106 connected to the inner cap 104 is sealed in the initial state and is not opened even if it is rotated.

[52] When the user presses down and rotates the outer cap 106 by applying a predetermined pressure to open the outer cap 106, the sealing of the anti-fake cut portion

36 is removed, and the inner cap 104 is simultaneously rotated, thus opening the outer cap 106. [53] The above-described outer cap 106 of the present invention includes a cylindrical outer cap body 32, a concave groove 34 formed in the middle of the top of the outer cap body 32, and the anti-fake cut portion 36 formed in the middle of the concave groove 34. [54] A plurality of guide projections 38 are spaced at regular intervals on the inner side of the outer cap body 32 so as to guide the connecting projections 24 formed in the inner cap 104 to be connected to the inner cap 104 at accurate positions during initial connection. [55] A plurality of rectangular stepped portions 40 are formed to project inward at regular intervals at the bottom of the guide projections 38, and a hemispherical projection 41 is formed on an inner surface of each of the stepped portions 40 to support the inner cap

104. [56] Moreover, the connecting members 42 are formed at the top of the guide projections

38 to be connected to the connecting projections 24 of the inner cap 104. [57] The outer cap 106 connected to the inner cap 104 in the above manner can freely rotate; however, in this case, the inner cap 104 is not opened. [58] Meanwhile, a plurality of support projections 44 are provided at regular intervals at the bottom of the stepped portions 40 formed on the inner side of the outer cap body 32.

[59] The support projections 44 have a hemispherical shape and are arranged at regular intervals such that, when the outer cap 106 is connected to the inner cap 104, the support projections 44 prevent the outer cap 106 from moving left and right.

[60] A plurality of elastic pieces 46 are formed to project downward from the ceiling of the outer cap body 32 at regular intervals.

[61] In a state in which the outer cap 106 is initially connected to the inner cap 104, the elastic pieces 46 fix the outer cap 106 and the inner cap 104 while maintaining a predetermined distance between the two caps, thus preventing excess movement of the outer cap 106. However, when the elastic pieces 46 are pressed down by applying a predetermined force to the outer cap 106, the elastic pieces 46 are pressed upward in a direction opposite to the externally applied force.

[62] A plurality of rectangular outer cap engaging projections 48 are formed to project downward at regular intervals on the ceiling surface of the outer cap body 32.

[63] The outer cap engaging projections 48 are located at positions corresponding to the inner cap engaging projections 22 such that, when the outer cap 106 is pressed, the engagement is made such that the outer cap engaging projections 48 are located adjacent to the inner cap engaging projections 22.

[64] FIG. 3 shows a state in which the anti-fake bottle cap 100 of the present invention is sealed, in which the inner cap 104 is connected and fixed to the fastening member 12 at the top of the bottle 102, and the outer cap 106 is connected to the connecting projections 24 at the top of the inner cap 104.

[65] At this time, the elastic pieces 46 formed on the inside of the outer cap 106 elastically support the top surface of the inner cap body 18.

[66] Since the elastic pieces 46 of the outer cap 106 press down the inner cap body 18 in the above manner, it is possible to prevent the outer cap 106 from being rotated by a small force or from freely moving up and down.

[67] FIG. 4 shows a state in which the sealing of the anti-fake bottle cap 100 of the present invention is removed. When the outer cap 106 is pressed down, the cutting member 20 formed in the inner cap body 18 rises, and thus the anti-fake cut portion 36 located at the top of the cutting member 20 is cut and separated therefrom.

[68] The cutting member 20 moves in the upward direction of the outer cap 106 and is then exposed to the outside.

[69] As such, when the outer cap body 32 is pressed down, the elastic pieces 46 formed on the inside thereof are elastically pressed down, the plurality of outer cap engaging projections 48 are also pressed down, and thus the outer cap engaging projections 48 are located on the side surfaces of the inner cap engaging projections 22 of the inner cap body 18 and engaged therewith.

[70] Since the outer cap engaging projections 48 of the outer cap body 32 are engaged with the inner cap engaging projections 22 of the inner cap body 18, when the outer cap 106 is rotated, the inner cap 104 is rotated by the rotation of the outer cap 106.

[71] At the same time, when the inner cap 104 is rotated, the fastening member 26 of the inner cap 104 connected to the fastening member 12 of the bottle 102 is released, and thus the inner cap 104 is opened from the bottle body 10.

[72] FIG. 6 is a perspective view showing the structure in which the anti-fake cut portion

36 of the anti-fake bottle cap 100 of the present invention is removed such that the opening state of the bottle 102 can be seen with naked eye.

[73] Meanwhile, when the anti-fake cut portion 36 of the anti-fake bottle cap 100 is cut and removed, various foreign materials such as water may be introduced through the hole formed at a position where the anti-fake cut portion 36 is removed.

[74] To this end, a foreign material entry preventing member 49 extending from the inner circumference of the concave groove 34 being in contact with the anti-fake cut portion 36 may be provided.

[75] Meanwhile, as shown in FIG. 3, it is preferable that an embossing (a) projecting from the lower surface of the foreign material entry preventing member 49 be provided.

[76] Referring to FIGS. 7 to 10, an anti-fake bottle cap 100 in accordance with another embodiment of the present invention includes an inner cap 104 connected to the top of a bottle 102 containing a liquid substance to prevent the substance contained in the bottle 102 from being discharged, and an outer cap 106, connected to the top of the inner cap 104 to prevent the inner cap 104 from being opened independently and including an anti-fake cut portion 37 through which a user can determine whether the substance is quantitatively contained in the bottle 102 and whether the bottle 102 has been opened by a stranger.

[77] A plurality of cut projections 39 are formed on the lower surface of the anti-fake cut portion 37.

[78] The inner cap 104 is connected to the top of the bottle 102.

[79] At this time, the inner cap 104 is connected to a fastening member 12 of a bottle body 10 and is closely connected to the outer cap 106 in the up and down direction.

[80] The side surfaces of inner cap engaging projections 22 formed on the inner cap 104 and the side surfaces of outer cap engaging projections 48 formed on the outer cap 106 are in close contact with each other, and the side surfaces of the cut projections 39 and the side surfaces of cutting projections 50 are in close contact with each other.

[81] It is preferable that one of the top surface of each of the inner cap engaging projections 22 and the bottom surface of each of the outer cap engaging projections 48 be subjected to an embossing treatment. [82] The inner cap 104 includes a cylindrical inner cap body 18 and a plurality of rectangular cutting projections 50 formed on the top of the inner cap body 18.

[83] The plurality of cutting projections 50 are formed in a circular shape at regular intervals.

[84] The plurality of cutting projections 50 cut the anti-fake cut portion 37 of the outer cap 106, which will be described later.

[85] The outer cap 106 connected to the inner cap 104 is sealed in the initial connection state.

[86] In order to open the inner cap 104, the outer cap 106 is rotated to rotate the inner cap

104 such that the sealing of the anti-fake cut portion 37 is removed and the inner cap 104 is simultaneously rotated, thus opening the bottle 102.

[87] At this time, in the process of cutting the anti-fake cut portion 37, the cutting projections 50 come in contact with the cut projections 39 of the anti-fake cut portion 37 to cut the cut projections 39 before the inner cap engaging projections 22 of the inner cap body 18 and the outer cap engaging projections 48 are in contact with each other, and then the outer engaging projections 48 come in contact with the inner cap engaging projections 22 to transmit the rotational force, thus rotating the inner cap 104.

[88] As a result, the anti-fake cut portion 37 of the outer cap 106 is first separated to remove the sealing thereof, and then the inner cap 104 is opened.

[89] Meanwhile, the objects of the present invention can be achieved in other embodiments shown in FIGS. 14 to 21.

[90] For example, the middle of an outer cap 106 is penetrated, and an anti-fake cut portion 36 for opening and closing the penetrated portion is connected by a rib. Elastic pieces 46 and outer cap engaging projections 48 are formed on the inner top surface of the outer cap 106. As shown in the bottom view of FIG. 15, the elastic pieces 46 and the outer cap engaging projections 48 are placed on the same line.

[91] If so, the elastic pieces 46 and the outer cap engaging projections 48 are simultaneously in contact with guide projections 23 and inner cap engaging projections 22 and rotated, thus providing a stronger fastening force.

[92] Meanwhile, the guide projections 23 and the inner cap engaging projections 22 are provided on the top surface of the inner cap 104. The guide projections 23 are located at the outer circumference of the inner cap 104 to be in lateral contact with the elastic pieces 46 located outwardly of the inner top surface of the outer cap 106. The inner cap engaging projections 22 are in lateral contact with the outer cap engaging projections 48 located inwardly of the inner top surface of the outer cap 106.

[93] Here, as shown in FIG. 14, each of the guide projections 23 includes a vertical surface 23a formed on one side and an inclined surface 23b formed on the other side and extending to the vertical surface 23 a. [94] Therefore, when the outer cap 106 is rotated in the opening direction without pressing down the outer cap 106, the elastic pieces 46 of the outer cap 106 go over the inclined surfaces 23b of the guide projections 23 such that the outer cap 106 and the inner cap 104 are not engaged with each other. That is, if the outer cap 106 is not pressed down, since the outer cap 106 is spaced apart from the top surface of the inner cap 104, the outer cap engaging projections 48 of the outer cap 106 and the inner cap engaging projections 22 of the inner cap 104 are not in contact with each other, and thus the outer cap 106 idles.

[95] Meanwhile, the shapes of the inner cap engaging projections 22 of the inner cap 104 are shown in FIGS. 4, 17 and 18.

[96] The inner cap engaging projections 22 project from the top surface of the inner cap

104 in the shape of a ring and are spaced at regular intervals based on a cutting member 20 which comes in contact with the circular anti-fake cut portion 36 provided on the top surface of the outer cap 106.

[97] As shown in the figures, each of the inner cap engaging projections 22 has a tapered inclined surface 22a, a vertical surface 22b vertically extending from the top end of the inclined surface 22a, and a guide surface 22c extending from the bottom end of the vertical surface 22b and gently tapered.

[98] As shown in FIG. 17, when the outer cap 106 is rotated in the opening direction without pressing down the outer cap 106, each of the outer cap engaging projections 48 of the outer cap 106 moves along the inclined surface 22a, each of the elastic pieces 46 of the outer cap 106 also moves along the inclined surface 23b of each of the guide projections 23 on the top surface of the inner cap 104, and thus the outer cap 106 idles.

[99] Moreover, when the outer cap 106 is rotated in the closing direction, each of the outer cap engaging projections 48 of the outer cap 106 comes in contact with the vertical surface 22b along the guide surface 22c such that the outer cap 106 and the inner cap 104 are simultaneously rotated and opened.

[100] Meanwhile, in order to open the anti-fake bottle cap 100 of the present invention, it is necessary to press down the outer cap 106.

[101] At this time, when the outer cap 106 is pressed down, the anti-fake cut portion 36 connected to the middle portion of the outer cap 106 by a rib should be separated.

[102] As shown in FIGS. 15 and 16, the outer cap 106 is pressed down such that a plurality of guide projections 48a projecting from the inner circumferential surface of the outer cap 106 and spaced at regular intervals are moved down along a plurality of grooves 104a formed on the outer circumferential surface of the top surface of the inner cap 104, and thus the entire outer cap 106 is moved down.

[103] In this case, it is preferable that the grooves 104a be positioned between the inner cap engaging projections 22 as shown in the plan view of FIG. 16. [104] As a result, when the user presses and rotates the outer cap 106, the outer cap 106 idles since the outer cap engaging projections 48 of the outer cap 106 and the inner cap engaging projections 22 of the inner cap 104 are not in contact with each other. When the guide projections 48a reach the grooves 104a of the inner cap 104, the outer cap 106 is moved down.

[105] As shown in FIG. 18, by the outer cap 106 moved down in the above manner, the ring-shaped cutting member 20 cuts the anti-fake cut portion 36 in the middle of the outer cap 106.

[106] Then, the guide projections 48a of the outer cap 106 are placed in the grooves 104a of the inner groove 104, and one side of each of the outer cap engaging projections 48 of the outer cap 106 is in contact with one side of each of the inner cap engaging projections 22 of the inner cap 104. Therefore, when the user continuously rotates the outer cap 106 in the opening direction, the outer cap 106 and the inner cap 104 are simultaneously rotated, and thus the outer cap 106 is opened from the bottle 102.

[107] Meanwhile, in the case where the anti-fake bottle cap of the present invention is applied to a medical bottle containing a liquid medicine. In this case, it is necessary to prevent moisture from entering the bottle during sterilization process. As shown in FIGS. 20 and 21, a foreign material entry preventing piece 49a covering a foreign material entry preventing member formed on the bottom surface of a through-hole (H) in the middle of the outer cap 106 is provided.

[108] In the case where the foreign material entry preventing piece 49a formed of a silicon material and surrounding the foreign material entry preventing member 49 at the bottom is provided, it is possible to prevent moisture, produced during the sterilization process of the medical bottle, from entering the bottle through a gap between the outer circumferential surface of the anti-fake cut portion 36 in the middle of the outer cap 106 and the inner circumferential surface of the through-hole (H), thus improving the reliability of the medicine contained in the bottle 102.

[109] The invention has been described in detail with reference to preferred embodiments thereof. However, it will be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
