The present invention relates to a bottle cap assembly, and more particularly, to a bottle cap assembly that is capable of constantly discharging a predetermined amount of contents while at the same time making it difficult to inflow falsified contents from the outside, To a bottle cap assembly.

Various types of bottle caps have been developed in order to prevent the problem of expensive forgery. For example, a structure in which a customer can directly check whether a bottle cap is opened or closed can be realized by a method of attaching a cover ring preliminarily partitioned with a cutting line at the lower end of a bottle cap or attaching a cover paper made of a vinyl or metal thin plate to the outside of the bottle cap Has been applied.

However, such a bottle cap structure is problematic in that it is difficult to apply to expensive bottles due to the low appearance. In addition, there is a drawback that the covering and the cover paper can be easily imitated and adhered, thereby decreasing reliability. That is, since the counterfeit liquor maker can not prevent the false liquor from being injected into the empty liquor bottles that have already been consumed, the consumers can not buy the liquor because they believe the liquor is inferior.

Due to these problems, anti-fake structures using a ball valve inside the cap of the cap have been developed and marketed in addition to cover paper and covering. Fig. 1 shows an example of a prior art cap structure using a ball valve.

Referring to Figure 1, a cap assembly 10 includes a valve assembly, a dispensing body 21, a collar 25, a cap 32, a tubular lid 37 and an outer ring 42.

The valve assembly includes a receiving portion 17 for engaging the inside of the inlet portion 13 and receiving two glass spheres 18 and a flange 20 adjacent to the inlet portion 13, (16). The discharge body 21 is fastened to the extension 22 of the tubular member 16. The collar 25 is joined to the neck 12 of the bottle 11 in a cylindrical shape and the upper end 26 is fixed to the discharge body 21 by ultrasonic welding or the like.

The cap 32 has a bottom 33 and a threaded portion 35 formed inwardly to engage with the threaded portion 24 on the discharge body 21 and sealingly closes the discharge body 21. [ The tubular lid 37 has an annular projection 40 for holding the cap 32 and is adjacent the annular portion 27 of the collar 25. The outer ring 42 joins the tubular lid 37 and the annular portion 27 of the collar 25 so that the strength is weak.

The prior art bottle cap assembly having such a configuration can exert its function sufficiently to prevent forgery of the bottle contents. However, when the bottle is tilted to discharge the contents, the amount of discharged water is small and when the bottle is tilted by rapid action, Which causes a blocking phenomenon that is not discharged at all.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an anti-counterfeiting bottle cap assembly which can reliably discharge an appropriate amount of contents and hardly cause occlusion.

Another object of the present invention is to provide an anti-counterfeit bottle cap assembly configured to be difficult to inflow fluid from the outside into the bottle.

The above and other objects of the present invention are also attained by the above-described and other objects of the present invention, which are accomplished by the provision of a cylinder-shaped inner passage, an outer cylinder disposed on the outer side of the inner cylinder to define an upper discharge passage between the inner passages, A discharge body having a bridge; A side wall extending downward from the discharge body coupling portion to define a lower discharge path therein and being press-fitted into the inner surface of the bottle body; A valve seat having a valve seat portion extending radially inwardly and having an upper outlet formed at the center thereof, and a movable member seat portion extending radially inwardly from a lower portion of the side wall and having a lower outlet formed at the center thereof; A valve plate placed on the valve seat so as to open and close the upper outlet; and a valve extending from the valve seat to the inside of the inner tube to guide the up and down movement of the valve seat and restrict horizontal movement; And a moving member which is placed on the moving member seating portion to open and close the lower outlet and is movable in the lower discharge path and presses the valve plate to open the upper outlet port .

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The bottle cap assembly of the present invention includes a discharge body 100, a valve body 130, a screw cap 150, a band 160, a holder 170, a valve 180, and a ball member 190.

2A and 2B are a plan view and a side sectional view of the discharge body 100. As shown in FIG.

The discharge body includes a substantially cylindrical inner cylinder 110, an outer cylinder 118 positioned on the outer side of the inner cylinder, a bridge 112 connecting the inner cylinder 110 and the outer cylinder 118, and a tapered cylindrical portion 124. The inner tube 110 is a cylindrical member having an upper plate 111 having a through hole 114 and an open lower end. In the preferred embodiment, the diameter of the lower end is slightly larger. The outer cylinder 118 having a larger diameter than the inner cylinder is a cylindrical member having both upper and lower ends opened. On the outer side of the outer cylinder 118, a male screw 120 for screwing the screw cap 150 is formed. At the lower end of the outer cylinder 118, a flange 122 extending radially outward from the outer cylinder 118 is formed. The flange 122 has an upper surface 123 on which the holder 170 to be described later is seated.

The bridge 112 is a plate-like member connecting the inner cylinder 110 and the outer cylinder 118, and six bridges 112 are arranged at equal angles in the preferred embodiment of the present invention. The bridge 122 projects from the inner surface of the outer tube 118 and extends to the inner surface of the inner tube 110 and the inner surface of the inner tube 110. As shown in Figure 2B in which some of the bridges 112 are omitted, And is fixed to the outer surface. The lower end 112b of the bridge 122 extends further downward than the lower end of the inner cylinder 110 and comes into contact with the upper surface of the valve plate 182 when the valve 180 to be described later moves vertically. The free end 112a of the bridge 112 protruding into the inner cylinder 110 serves to guide the movement of the head 184 of the valve 180. [

With this configuration, the space between the inner cylinder 110 and the outer cylinder 118 is formed with an upper discharge passage 116 partitioned by a plurality of bridges 112, through which the contents of the bottle are discharged.

The tapered cylindrical portion 124 forms the upper end of the discharge body 100 and is configured to have a smaller diameter toward the lower side.

Figures 3a and 3b show a top view and a side cross-sectional view of the valve body 130.

The valve body 130 includes a cylindrical discharge body coupling portion 144, a flange 138 extending radially outward at a lower end of the discharge body coupling portion 144, and a flange 138 extending downward from the discharge body coupling portion 144 And a cylindrical ball guide 142.

The discharge body coupling portion 144 has an outer surface that is press-fitted into the inner surface of the outer cylinder 118 of the discharge body 100. An annular projection 136 is formed on the outer surface of the discharge body coupling portion 144 to enhance the effect of press-

The lower surface of the flange 138 is seated on the upper surface of the bottle when the bottle cap assembly is assembled into the bottle and the upper surface of the flange 138 is connected to the upper surface of the flange 122 of the discharge body 100 when the valve body 130 and the discharge body 100 are engaged. And is in contact with the lower surface.

The ball guide portion 142 includes a side wall 149 extending downward from it coaxially with the discharge body coupling portion 144 and having a lower discharge passage 145 therein. A valve seating portion 134 extending radially inwardly from the side wall 149 is formed at an upper portion of the side wall 149 and a ball seating portion 140 extending radially inwardly from the side wall 149 is formed at a lower portion . An upper outlet 147 is formed through the center of the valve seat 134 and a lower outlet 143 is formed through the center of the ball seat 140. A plurality of plate-like guide plates 141 protruding from the inner surface of the side wall 149 come into contact with the ball member 190 at the free end thereof. When the ball member 190 is seated on the ball receiving portion 140, a part of the ball member 190 protrudes downward from the lower outlet 143, while the ball receiving portion 140 is in contact with the lower outlet 143 are closed.

Screw cap 150 is shown in Figures 4a and 4b. The screw cap 150 has a cylindrical shape with an upper end closed and a lower end opened, and is engaged with the discharge body 100 to completely block the upper discharge path 116. The screw cap 150 has a top plate 151 formed on the top thereof and a female screw 156 formed on the inner surface of the side wall 153. Further, the upper plate 151 is provided with a central projection 154 and a packing 158 protruding downward from the center thereof. The central protrusion 154 is coupled to the guide groove 188 formed in the valve 180 to be described later when the screw cap 150 is coupled to the discharging body 100 so that the discharging body 100 and the valve body 130 So that the center of the valve 180 is always aligned with the center of the valve seat 134, that is, in the center of the bottle cap assembly. The packing 158 has an outer surface 159 that elastically contacts the inner surface of the tapered cylindrical portion 124 of the discharging body 100 so that when the screw cap 150 is coupled to the discharging body 100, To prevent leakage to the outside.

Bands 160 are shown in Figures 5A and 5B. The band 160 functions together with the holder 170 to be described later so that the discharge body 100 and the valve body 130 can be more firmly held in the bottle. The band 160 includes first and second inner sides 163 and 164 in contact with the holder 170, a beveled cylindrical portion 162 coupled to a side projecting portion (not shown) of the bottle neck, And includes a series of protrusions 166 in contact therewith.

The first and second inner sides 163 and 164 are contacted and engaged with the lower end of the holder 170 and the upper free end of the oblique cylindrical portion 162 is engaged with the bottom end of the bottle 170. [ As shown in Fig. 8A, the inclined cylindrical portion 162 has a shape in which the process of separating the band 160 from the bottle neck is difficult, while the process of coupling the band 160 from the upper side is facilitated, Thereby forming a lock portion that prevents the bottle from falling off easily from the bottle neck. The protrusion 166 also engages a corresponding protrusion 166a formed on the outer surface of the bottle neck to prevent the band 160 from rotating easily around the bottle neck.

6A and 6B, a holder 170 is shown. The holder 170 includes a body 172 and first and second outer sides 175 and 176 formed at the bottom of the body 172 and corresponding to the first and second inner sides 163 and 164 of the band, And a triangular projection 174 in which a triangular projection having a lower end contacting with the upper surface of the flange 122 of the discharge body 100 is arranged in a circular shape.

7A and 7B show a valve 180. In Fig. The valve 180 functions to open and close the upper discharge port 147 and the lower discharge path 145 and is constituted by a valve plate 182 and a head 184. The valve plate 182 is a circular plate having a diameter larger than that of the valve seat 134 and has a plurality of aeration slits 186 and a bottom surface contacting the valve seat 134 and a lower end 112b of the bridge 112 And has an upper surface in contact therewith.

A plurality of aeration slits 186 are arranged at approximately an equal angle to the outer periphery of the valve plate 182. Even when the valve plate 182 moves horizontally and the center of the valve plate 182 and the center of the valve seat 134 do not coincide with each other, at least one of the vent slits 186 always reaches the lower discharge passage 145, The size and disposition of the aeration slit 186 is determined so as to communicate with the passage 116.

The head 184 extending upward from the valve plate 182 is received in the inner cylinder 110 of the discharge body 100 as shown in FIG. 8A when the bottle cap assembly is mounted on the bottle, And is configured such that its horizontal movement is restricted by the free end 112a. By restricting the horizontal movement of the head 184, the position and posture of the valve plate 182 can be limited. The head 184 is provided at its upper portion with a guide groove 188 whose one end is closed. The center protruding portion 154 of the screw cap 150 is inserted into the guide groove 188 so that the guide groove 188 can be inserted at any time regardless of the position of the head 184, The guide groove 188 adjacent to the upper surface of the head 184 is rounded.

A state in which the bottle cap assembly having the above-described configuration is mounted on the bottle is shown in Fig. The state shown is that the bottle is standing vertically.

As shown in FIG. 8A, the side wall 149 is press-fitted into the inner surface 202 of the bottle 200. The discharge body coupling portion 144 of the valve body 130 is tightly press-fitted to the outer cylinder 118 of the discharge body 100 by the annular projection 136. The valve 180 is positioned in the space formed by the discharge body 100 and the valve body 130 and the lower surface of the valve plate 182 is positioned on the upper surface of the valve seat 134 to close the upper outlet 147 And a ball member 190 closes the lower outlet 143 at a lower portion of the valve 180.

The holder 170 and the band 160 are coupled to each other to support the discharge body 100 and the valve body 130 so that they are firmly coupled to the bottle 200.

When the bottle is standing upright as shown in the figure, in the bottle cap assembly of the present invention, the upper discharge path 116 and the lower discharge path 145 are blocked by the valve plate 182 located at the valve seat 134 , The ball member 190 is located at the ball receiving portion 134 and closes the lower outlet 143, so that it is difficult to easily introduce the forgery from the outside.

Particularly when the valve plate 182 separated from the valve seat 134 returns to the valve seat 134, the position of the head 184 extending from the valve plate 182 in the horizontal direction becomes the bridge 112 so that the valve plate 182 is always aligned with the position completely covering the upper outlet 147. [ The gap between the free end 112a of the bridge 112 and the head 184 is set in consideration of the operation of the valve plate 182 in the present invention. It will be appreciated, however, that the above-described action is possible even if the diameter of the valve plate 182 is made much larger than the diameter of the valve seat portion 134. Since the valve plate 182 completely covers the upper outlet 147 at all times, an attempt to inject the contents falsified from the outside into the bottle is hardly succeeded by the valve 180 of the present invention.

In addition, even if the forged contents can flow into the lower discharge passage 145 through the upper discharge port 147, since the lower discharge port 143 is blocked by the ball member 190, Inflow of contents is almost impossible.

8B, when the bottle is inclined as shown in FIG. 8B, the ball member 190 is detached from the ball receiving portion 140 while opening the lower outlet 143, (141) toward the inlet of the bottle to press the valve plate (182). The upper surface of the valve plate 182 contacts the lower end 112b of the bridge 112 to open the upper outlet 147 and the lower outlet 145. [

In this process, since the ball member 190 moves along with the contents of the liquid bottle in the lower discharge path 145, the moving speed may be reduced due to the resistance of the fluid or the like. For this reason, The valve plate 182 may begin to move first to open a portion of the top outlet 147 and the ball member 190 may contact and press the valve plate 182 a little later. The ball member 190 also contacts the lower end 112b of the bridge 112 so that the upper outlet 147 can be reliably opened. It is preferable that the ball member 190 has a larger weight than the valve 180 for such a function.

According to the present invention, the ball member 190 is configured to start to move when the bottle is tilted from about 85 degrees to about 90 degrees, preferably about 88 degrees, from the state shown in Figure 8a.

This state is a state in which the bottle is almost in a lying state. Therefore, even if an attempt is made to infiltrate the forgery contents through the upper and lower discharge passages 116 and 145 opened by using a tool such as a syringe or the like, It is hard to fill all of them.

The ventilation slit 186 of the valve plate 182 allows the lower discharge passage 145 and the upper discharge passage 116 to communicate with each other within a certain range even when the valve plate 182 completely closes the valve seat portion 134. [ Communicate. By such a configuration, the occurrence of occlusion, which often occurs when the bottle tilting speed and the tilting and maintaining angle have a certain value, can be much reduced. That is, in order for the fluid to flow out of the bottle, a corresponding amount of gas must flow from the outside of the bottle. The vent slit 186 allows the inside of the bottle and the outside air atmosphere is communicated with each other within a certain range, it is possible to ensure the inflow of outside air when the contents are discharged.

Although the preferred embodiments of the present invention have been described with reference to the accompanying drawings, it is to be understood that the present invention is not limited to the above-described embodiments and that other embodiments are possible without departing from the scope of the present invention. It will be possible.

 In the bottle cap assembly of the present invention, since the upper outlet is blocked by the valve and the lower outlet is blocked by the ball member, it is difficult to introduce the contents even when a bottle or syringe is used upright Do. Further, since the valve is configured to be opened in a state in which the bottle is almost horizontally arranged, even in such a state, even if the forgery contents or the like is tried to flow through the discharge port opened by using the above-described tool or the like, .

Further, since the valve plate of the valve used in the cap assembly of the present invention is provided with a plurality of the vent slits, the inflow of the outside air necessary for releasing the contents is guaranteed, and the opening of the valve plate is surely ensured by the ball member having a large weight , The rate at which the bottle is tilted, and the occlusion phenomena often occurring when the tilting and maintaining angle has a certain value.
