The present invention relates to a bottle (bottle) and a bottle cap, and more specifically, the opening of the bottle cap is impossible when the exact opening method is not known, so the risk of misuse due to misunderstanding and confusion of the contents is small, and is opened once. It is related to the bottle and the bottle cap which can not be forged in the opening fact because the appearance is quite different from before opening.

In our daily life, a bottle, which is mainly used to contain liquids, is a generic name for a narrow-necked bowl. It is usually a bottleneck of narrow shape as the diameter decreases gradually from the bottom of the tubular body to the upper end. It forms a bottle neck with an open mouth at its end. Therefore, through the bottle opening of the bottle erected at a certain angle it can be injected and stored the desired material, on the contrary, the bottle can be tilted so that the bottle facing the direction of gravity can extract the contents.

On the other hand, the bottle opening of the common bottle is sealed with a bottle cap to ensure the reliability of storage and storage of the contents, for which the bottle cap, unlike the crown (cap), cap (cap), cover, lid or closure (closure) Also called), it can be classified in various ways based on its material, shape, or use.

Attached FIG. 1 is an exploded perspective view of a general bottle 10 and a bottle cap 20, and the bottle cap 20 can be easily opened or sealed with a small force, for example, and is widely used for wine, beverages, medicine bottles, etc. A twist-off type cap 20 (hereinafter referred to as bottle cap 20) is shown.

As can be seen, the general bottle 10 is gradually reduced in diameter from the bottom of the tubular body 12 with a closed bottom to form a bottleneck 14 having a narrow shape, and the bottle opening 16 is opened at the end thereof. A first thread 18 is provided along the outer surface of the bottleneck 14 near the bottle opening 16. And the bottle cap 20 which opens or closes the bottle opening 16 of this bottle 10 shows the cap shape which covers the upper end part of the bottle neck 14 including the bottle opening 16, The inner surface which faces the bottleneck 14 is shown. A second thread 22 is thus provided.

Therefore, when the bottle cap 20 is covered with the bottle cap 20 and the bottle cap 20 is rotated in the tightening direction of the first and second threads 18 and 22, the bottle cap 16 is sealed and the reverse direction of the loosening is reversed. When the bottle cap 20 is rotated and separated, the bottle opening 16 is opened.

However, while the general bottle 10 and the bottle cap 20 described above show the advantages of being easily opened or closed, there are some disadvantages caused by this.

First, anyone can easily open the bottle cap (20), even if the poison or other toxic substances stored in the bottle (10) is not aware of this or misunderstandings of misunderstanding or confusion of the contents, such as open drinking by children lacking cognitive ability The risk is great.

Second, there is almost no change in appearance due to reclosing after the initial opening of the bottle cap 20, so that the forgery of the contents, for example, exchange of expensive liquor for cheap liquor, is high. Accordingly, a separate annular sleeve surrounding the bottleneck 14 is connected to the lower end of the bottle cap 20 by a bridge so that the sleeve is separated from the bottle cap 20 at the time of initial opening. Of Pilfer Proof) Although a stopper was introduced, it is also difficult to check whether it is opened since the sleeve separated from the bottle stopper 20 remains completely in the bottleneck 14.

Third, the common bottle cap 20 has a high possibility of inflow of external air, and even if a small amount of the contents are frequently leaked, there is a possibility of deterioration. Fourth, after the bottle cap 20 is opened, the contents can be easily replaced. There is a great possibility of counterfeiting.

The present invention has been made to solve the above problems, the first time the opening of the bottle cap (open) if you do not know the correct opening method is impossible to open the risk of misuse due to misunderstanding or confusion of the contents, after the first opening (Iii) The purpose is to provide bottles and caps that cannot be tampered with.

To this end, the present invention is specifically impossible to open the bottle cap from the bottle opening, unless the first opening of the bottle cap is taken separately, and after the initial opening (後) whether the forgery accompanied by the apparent change It provides a concrete way that can be easily identified with the naked eye, and also adds stability to storage and storage by reducing the possibility of leakage of contents and inflow of external air in a sealed cap, and re-injection after opening of the cap This difficulty is to provide a bottle and cap that can further increase the anti-counterfeiting reliability.

Hereinafter, the present invention will be described in more detail with reference to the drawings.

2 is an exploded perspective view of the bottle 50 and the bottle cap 60 according to the present invention, in the case of the bottle cap 60 is shown upside down along the coupling line (a) to show its internal structure for convenience, The lower part of the figure corresponds to the upper end of the actual bottle cap 60 on the basis of the closed state of the bottle cap 60 for the standing bottle 50. In order to avoid this confusion, below, the upper and lower sides are defined based on the sealed state of the bottle cap 60 with respect to the upright bottle 50.

First, the bottle 50 according to the present invention forms a bottleneck 52 having a concave shape as the diameter decreases toward the top from the bottom of a tubular body 51 with a closed bottom, and the bottle opening 54 is opened at the end thereof. This provides a storage space in which liquids and the like can be stored. An annular lug 56 is enclosed at a predetermined position of the double bottleneck 52, and a higher position, for example, at least one first protrusion 58 is provided along the end of the bottleneck 52. Bars these lugs 56 and first protrusions 58 may be integrally formed with the bottle 50.

Next, the bottle cap 60 may be divided into a discharge stopper 70 covering the bottle opening 54 and a sealing stopper 160 covering the discharge stopper 70.

Of these, the discharge stopper 70 shows a cap shape that is covered on the top of the bottleneck 52 to cover the bottle opening 54, and still remain in the position after opening the bottle 50 to maintain the state of engagement with the bottle 50 As a retaining portion, there is an annular stepped portion 84 in close contact with the bottle opening 54 with the discharge hole 82 penetrating up and down, and at the same time in a hook manner along the lower inner surface thereof. The locking end 114 which hangs on the lug 56 of the bottleneck 52 is provided. In addition, at least one second protrusion 90 engaged with the first protrusion 58 of the bottleneck 52 is provided inside the discharge stopper 70, for example, along the back surface of the step 84. Along the outer surface of the 70 is provided a first thread 120, including at least one first locking step 116.

Therefore, after covering the bottle opening 54 with the discharge plug 70 and adding a predetermined pressure, the stepped portion 84 is in close contact with the bottle opening 54, and the locking end 114 is caught by the lug 56 and press-fitted. As a result, the first and second protrusions 58 and 90 are engaged with each other, and the bottle opening 54 is exposed to the outside through the discharge hole 82. As a result, the contents inside the bottle 50 represent a state capable of being discharged to the outside through the bottle inlet 54 and the discharge hole 82, and thus the state in which the discharge stopper 70 is press-fitted to the bottle 50 The actual bottle 50 is opened. On the other hand, since the coupling of the bottle 50 and the discharge stopper 70 is due to the simple locking structure between the lug 56 and the locking end 114, when the rotational force is applied to a predetermined level or more, the discharge stopper 70 maintains its coupling state. It can be rotated while holding it.

Next, the sealing stopper 160 has a cap shape covering the entire discharge stopper 70 including the discharge hole 82, and is coupled or separated by a screw method to the discharge stopper 70 to substantially seal the bottle opening 54. Or as a part to open, the 2nd thread 172 corresponding to the 1st thread 120 is provided along the inner surface. In addition, along the lower end of the sealing stopper 160, an annular sleeve 182 covering the outer surface of the discharge stopper 70 is connected by a bridge by the cutting line 192 (see 194 in FIG. 9A, hereinafter the same). It is made to be forcibly separated by a user's selection, and the inner surface of the sleeve 182 is provided with at least one second locking jaw 184 that engages with the first locking jaw 116.

Therefore, after the discharge stopper 70 is press-fitted to the bottle 50, that is, the discharge stopper 70 is covered with the sealing stopper 160 in the open state of the bottle 50, the first and second threads 120 and 172 are covered. When the sealing stopper 160 is rotated in the tightening direction, the discharge hole 82 including the bottle opening 54 is blocked to seal the bottle 50 and the first and second locking jaws 116 and 184 are engaged with each other. As such, the discharge stopper 70 is press-fitted to the bottle 50, and the sealing stopper 160 is screwed to the discharge stopper 70 to become a substantially sealed state of the bottle 50.

On the other hand, in order to open the bottle 50 from such a closed state, the user rotates the sealing cap 160 in the unwinding direction of the first and second threads 120 and 172, in particular the bottle cap 60 according to the present invention is a sleeve Before the removal of the 182, the entirety of the bottle cap 60 can not be opened due to the looseness from the bottle 50, and only after the sleeve 182 is removed, the sealing cap 160 is discharged. From 70).

A component for this purpose is the first projection 58 at the end of the bottleneck 52 and the second projection 90 of the discharge plug 70 and the first locking projection 116 and the sealing stopper 160 of the discharge stopper 70. The second engaging jaw 184 is provided in the sleeve 182 of the first, the degree of engagement of the first and second engaging jaws (116, 184) before the sleeve 182 is removed, the engagement of the first and second projections (58, 90). Stronger than that, the entire bottle cap 60 turns away from the bottle 50, and after the sleeve 182 is removed, the degree of engagement of the first and second protrusions 58,90 is the degree of engagement of the first second threads 120,172. Stronger seal plug 160 may be rotated and separated from the discharge plug (70).

More specifically, when the sealing cap 160 is rotated in the unwinding direction of the first and second threads 120 and 172 in the closed state of the bottle 50 and the bottle cap 60 according to the present invention, various resistance forces against the rotational force F are obtained. In general, rotational suppression force appears.

The rotational suppression force due to the engagement of the first and second protrusions 58 and 90 is called F1, and the rotational suppression force due to the engagement of the first and second locking jaws 116 and 184 before the sleeve 182 is removed. Denotes F2, and when the sleeve 182 is removed and the rotational suppression force due to the frictional force of the first and second threads 120 and 172 is F3, they show a relationship of F> F2> F1> F3. Separately, assuming that the coupling force of the sealing plug 160 and the sleeve 182 by the bridge 194 is F4, the relationship of F4> F> F2> F1> F3 is shown, where F4> F is eventually the sealing plug 160. Only the rotational force (F) of the user applied to the means that the bridge 194 is not broken.

Therefore, when the user rotates the sealing stopper 160 in the opening direction without removing the sleeve 182, the second protrusion 90 overtakes the first protrusion 58 by the relationship of F> F2> F1. The first and second catching jaws 116 and 184 remain in engagement with each other, such that the entirety of the sealing cap 160 including the discharge cap 70 turns from the bottle 50. However, if the sealing plug 160 is rotated in the opening direction after the sleeve 182 is removed, F2 is lost and thus becomes a relationship of F> F1> F3, and the first and second protrusions 58 and 90 maintain their engagement state. The discharge stopper 70 is fixed to the bottle opening 54, while the first and second threads 120 and 172 are loosened so that the sealing stopper 160 is rotated and separated from the discharge stopper 70.

As a result, the bottle 50 and the bottle cap 60 according to the present invention are impossible to open the bottle cap 60 from the bottle 50 before the sleeve 182 is removed, and only after the sleeve 182 is removed. The sealing stopper 160 may be rotated and opened from the discharge stopper 70.

In this case, the sleeve 182 including the first and second protrusions 58 and 90 and the first and second locking jaws 116 and 184 to represent the above relationship, that is, the relationship of F4> F> F2> F1> F3. Silver can exhibit several characteristics in terms of material and shape.

First, on the premise that the bottle 50 and the first protrusion 58 are made of the same glass, the second protrusion 90 including the discharge stopper 70, the first locking jaw 116, and the sealing stopper 160 are included. The sleeve 182 and the second locking jaw 184 may be made of a relatively weak synthetic resin material. In addition, each of the first protrusions 58 may have a hemispherical shape or a rounded shape of an outer surface thereof so that the second protrusions 90 may be turned over by a predetermined force or more, and the first and second locking jaws ( 116, 184 is in the closed state of the bottle cap 60 to maintain the engagement state until the sleeve 182 is removed once the engagement stops naturally when the discharge stopper 70 and the sealing stopper 160 is engaged. It can be shown that the ratchet shape that is interlaced with each other in.

In addition, the number of the first and second protrusions 58 and 90 and the first and second locking jaws 116 and 184 may be properly adjusted for the corresponding action, but the first protrusion 58 may be used to exert unbiased rotational suppression force. A plurality of bottles are arranged at equal intervals along the ends of the bottleneck 52, and the second protrusions 90 are arranged at equal intervals along the rear surface of the step 84, and the first and second locking jaws 116 and 184. Each of the plurality may be arranged at the same pitch in a one-to-one correspondence along the outer surface of the discharge plug 70 and the inner surface of the sleeve 182.

In addition, the number and shape of the bridges 194 connecting the sealing plug 160 and the sleeve 182 may be appropriately adjusted to show the relationship of F4> F, which can be easily understood by those skilled in the art without further explanation. will be.

On the other hand, in the above-described information, the resistance force appearing between the bottle 50 and the discharge stopper 70 according to the rotational force (F) applied by the user to the sealing stopper 160 is the first and second projections (58, 90) In addition to the rotational suppression force F1 due to the engagement, frictional force between the bottle opening 54 and the stepped 84 or frictional force between the lug 56 and the locking end 114 may be considered, but the influence thereof is not so large. It can be regarded as included, and the same applies to F2, F3, F4. Thus, unless otherwise stated, F1 refers to all types of resistance forces that appear between the bottle 50 and the discharge cap 70, including the engagement of the first and second protrusions 58,90, and F2 denotes the sleeve ( 182, the rotational suppression force by the engagement of the first and second locking jaws (116, 184) before the removal, as well as all kinds of resistive forces appearing between the discharge plug 70 and the sealing plug 160, F3 refers to the frictional force between the first and second threads 120 and 172 after the removal of the sleeve 182, as well as all kinds of resistive forces appearing between the discharge plug 70 and the sealing plug 160.

As described above, the bottle cap 60 according to the present invention can be opened only when the sleeve 182 is removed, and thus, the bottle cap 60 may not be actually opened when the opening method is not exactly known. Therefore, children who do not know well the substance stored in the bottle 50 or lack of cognitive ability, such as drinking open easily the bottle cap 60 can greatly reduce the possibility of misuse by misunderstanding or confusion of the contents.

In addition, the bottle cap 60 according to the present invention can be opened only by removing the sleeve 182, so that the presence of the sleeve 182 can be easily checked whether the bottle cap 60 is opened, and whether the counterfeit can be confirmed through this. Do. At this time, especially when the sleeve 182 is removed, if the sleeve 182 is completely damaged and the regeneration is impossible, the appearance of the sleeve 182 may be increased to enhance the anti-counterfeiting function, and the material of the sleeve 182 may be soft. It is selected from polystyrene-based, preferably high-impact polystyrene (HIPS), which is easily broken due to its low malleability, and gives an appropriate number of rupture grooves 186 along the length thereof in the vertical direction. 182 may be separated into several pieces along each rupture groove 186 upon removal.

And, apart from this, the first handle 188 may be provided at one side thereof so that the user can easily remove the sleeve 182, whereby the user pulls the first handle 188 to operate the sleeve 182. ) Can be separated to break the bridge 194 in turn along the perforation line 192, during which the sleeve 182 is separated into several pieces by each rupture groove 186.

Further, the bottle cap 60 according to the present invention may be provided with some additional components for enhancing the anti-counterfeiting function, the details of which may be divided into several embodiments. Therefore, the following description will be made by dividing each embodiment. For convenience, the same reference numerals are assigned to the same elements that perform the same roles as the above-described parts, and thus, overlapping descriptions are avoided. Instead of going through the examples, I mention only the specific features.

Therefore, when the internal discharge stopper 80 is press-fitted into the bottle opening 54 and then covered with the external discharge stopper 100 and the pressure is added, the third guide end 94 of the internal discharge stopper 80 is the fifth guide end. At the same time, the inner end stopper 80, including the external discharge stopper 100, is tightly coupled to the bottle opening 54 while the locking end 114 is caught by the lug 56 at the same time. The second rotation inhibiting projections 92 and 110 mesh with each other, and the discharge holes 82 are exposed to the outside through at least one discharge hole 102, that is, the first and second discharge holes 104 and 106. In this case, the first and external discharge stoppers 80 and 100 are coupled to each other to form a discharge stopper 70. As such, the internal discharge stopper 80 is coupled to the bottle opening 54, and external to the internal discharge stopper 80. As described above, the discharge stopper 100 is coupled, that is, the discharge stopper 70 is coupled to the bottle opening 54 to be a substantially open state of the bottle 50.

The first and second rotation inhibiting projections 92 and 110 meshing with each other during this process prevent the idling between the internal and external discharge stoppers 80 and 100 so as to function substantially as a unit, and the rotation suppression force due to their engagement is at least F. Big.

On the other hand, the above-described external discharge cap 100 can be divided into two parts of the upper and lower sides as necessary, the modification is shown in FIG. In this case, the same reference numerals are given to the same parts performing the same role as those described above in order to avoid duplicate explanation.

As shown, the external discharge plug 100 may represent a form in which the upper and lower portions are separated along a predetermined point of the fourth guide end 112 higher than the locking end 114. , The lower fourth guide end 112b including the locking end 114 is first inserted into the bottleneck 52, and then the internal discharge stopper 70 is press-fitted into the bottle opening 54, and then the external discharge stopper 100 is inserted into the bottleneck 52. After covering the inner discharge stopper 70 with the remaining elements of the upper fourth guide end 112a or more, and ultrasonically welding the close contact portions of the upper and lower fourth guide ends 112a and 112b to have the same shape as that of FIGS. 5A to 5D. can do.

In this case, in order to increase the coupling reliability of the ultrasonic welding, a predetermined uneven shape may be provided along the close contact portion of the upper and lower fourth guide ends 112a and 112b.

Subsequently, FIGS. 7A to 7C are attached to the middle plug 130 and correspond to side views, cross-sectional views, and plan views, respectively. Reference is made to these figures in conjunction with Figures 3, 4A-4D and 5A-5D above.

As shown, the intermediate stopper 130 serves to seal the discharge port 102 by covering the upper surface of the external discharge stopper 100 and is a part separately removed by the user when the bottle cap 60 is first opened.

And the rotational suppression force due to their engagement is at least greater than F.

10 is an exploded cross-sectional view of the bottle 50 and the bottle cap 60 according to the first embodiment of the present invention, Figure 11 is a cross-sectional view of the coupling, with reference to Figure 2 below with reference to the assembly method thereof see.

In order to assemble the bottle cap 60 according to the present invention into the bottle 50, first, the internal discharge cap 80 is press-fitted into the bottle opening 54. To this end, the internal discharge plug 70 is properly positioned at the bottle opening 54, and then pressure is applied so that the inner and outer surfaces of the bottle opening 54 are inserted between the first and second guide ends 86 and 88. The two projections 90 engage the first projections 58 at the ends of the bottleneck 52.

Subsequently, the inner discharging stopper 70 is covered with the outer discharging stopper 100, and then pressure is applied to the locking end 114 of the fourth guide end 112 by hanging on the lug 56 of the bottleneck 52. . As a result, the third guide end 94 of the internal discharge stopper 70 is fitted into the fifth guide end 118 of the external discharge stopper 100, and the first and second rotational restraining protrusions 92 and 110 are engaged with each other. Combined. At this time, although not given a separate reference numerals, the projections and grooves of the concave-convex shape that are engaged with each other on the outer surface of the third guide end 94 of the inner discharge stopper 70 and the inner surface of the fifth guide end 118 of the outer discharge stopper 100. This may be provided correspondingly.

And the bottle 50 is opened by the step to here.

Next, the middle plug 130 is covered on the top surface of the external discharge plug 100, and then pressure is applied to each hook end 134 to the locking step 122. As a result, the bottle opening 54 has an intermediate stopper 130 including internal and external discharge stoppers 80 and 100, and the discharge hole 82 and the external discharge stopper 100 of the bottle opening 54 and the internal discharge stopper 80. All of the discharge holes 102 are sealed by the intermediate plug 130. At this time, if the external discharge plug 100 has been seen that can be separated into the upper and lower end of the fourth guide end 112, the assembly method according to this has already been described.

Subsequently, the deformation plate 178 is covered on the upper surface of the inner sealing stopper 170, and then inserted into the outer sealing stopper 180. As a result, the inner and outer sealing stoppers 170 and 180 are fastened with the fastening protrusion 174 and the fastening groove 196. Including is fixed integrally by the first and second coupling protrusions (176,198). As a result, a sealing stopper 160 is obtained.

Finally, the cap 50 is closed by covering the discharge cap 100 including the middle cap 130 with the sealing cap 160 and rotating in the coupling direction of the first and second threads 120 and 172.

Hereinafter, a method of opening the bottle cap 60 according to the present invention will be described with reference to FIGS. 12A to 12C. At this time, the corresponding drawings are a cross-sectional view showing the opening order of the bottle cap 60 according to the present invention, so that the reference numerals are omitted except for parts necessary for the description, Figures 3, 4a to 4d, 5a to 5d 7A and 7C, 8A to 8C, 9A to 9C, 10 and 11 as appropriate.

First, in a state where the bottle 50 is closed by the bottle cap 50 according to the present invention as shown in FIG. 11, the user grasps the first handle 188 provided at one side of the sleeve 182 and the bridge 194 is broken in turn. Pull the sleeve 182 to remove it along the perforation line 192. At this time, since the plurality of rupture grooves 186 are formed in the sleeve 182, the plurality of tear grooves 186 may be separated from each other and the regeneration is impossible, and the sleeve 182 may be completely removed from the bottleneck 52.

As a result, when the sleeve 182 is removed as shown in 12a, the user grasps the outer sealing stopper 180 and rotates in the opening direction. Accordingly, the sealing stopper 160 is released from the discharge stopper 70 so that the sealing stopper 160 is closed. It is separated from the discharge plug 70.

Thus, when the intermediate plug 130 is exposed as shown in FIG. 12B, the user grasps the second handle 140 of the intermediate plug 130 and tears it along the weakening line 142 to remove the intermediate plug 130 from the external discharge plug 100. 12C, the bottle opening 54 and the discharge hole 82 of the first discharge stopper 80 are exposed to the outside through the discharge hole 102 of the external discharge stopper 100 as shown in FIG. 12C.

This opened the bottle 50 according to the present invention.

On the other hand, without removing the sleeve 182 according to the normal method in the above-described process, for the purpose of forging may be considered a method of forcibly extracting the entire sleeve 182, including the outer sealing plug 180 vertically upwards, As shown in the enlarged view of the circle in FIG. 8B, the fastening protrusion 174 provided on the outer surface of the inner sealing stopper 170 has a gentle inclination, while the bottom thereof shows an inclination close to 90 ° from the side of the inner sealing stopper 170. Therefore, it is relatively easy to insert the inner sealing stopper 170 from the bottom of the outer sealing stopper 180 upward, but vice versa, forcibly extracting the outer sealing stopper 180 upward of the inner sealing stopper 170 is very easy. In this case, the end of the deformable plate 198 covering the upper surface of the inner sealing stopper 170 is caught on the inner surface of the outer sealing stopper 180, resulting in shape deformation.

And even if the inner and outer sealing caps 170 and 180 are opened by other methods, it is difficult to extract and inject the contents without removing the middle cap 130, and when the middle cap 130 is removed, the apparent change appears again. You can easily check forgery.

Second embodiment

13 is an exploded perspective view showing the bottle cap 60 according to the second embodiment of the present invention, and shows a structure substantially similar to that of the first embodiment.

However, in the bottle cap 60 according to the second embodiment of the present invention, the sleeve 182 is not connected to the lower end of the outer sealing cap 180 by the cut line 192 at the lower end of the inner sealing cap 170 (FIG. 14 of 194, which is the same below), and a separate inner plug 150 is interposed between the internal and external discharge plugs 80 and 100 instead of the intermediate plug (see 130 of FIG. 3). It is different.

At this time, the difference between the former, that is, even if the sleeve 182 is connected to the lower end of the first sealing cap 170, the bottle cap 60 according to the present invention has the same action, that is, the bottle cap 60 before removing the sleeve 182 While it is impossible to unseal the whole from the bottle 50, it can be easily understood based on the above description that the sealing stopper 160 can be rotated and opened from the discharge stopper 70 after removing the sleeve 182. In this way, there is no special technical difficulty in connecting the sleeve 182 to the lower end of the inner sealing stopper 170 rather than the outer sealing stop 180, so that a separate description may be omitted.

On the other hand, the latter plug 150 is a unique component that can be found only in the second embodiment of the bottle cap 60 according to the present invention, Figure 14 and the exploded cross-sectional view of the bottle cap according to the present embodiment Referring to FIG. 15 together with the cross-sectional view, the inner stopper 150 is interposed between the inner and outer discharge stoppers 80 and 100 to selectively seal the discharge hole 82 of the inner discharge stopper 80 according to the inclination angle of the bottle. Act as a valve. To this end, the stopper 150 may have a cup shape that is interposed in the third guide end 94 of the inner discharge stopper 80.

16A to 16B are cross-sectional views illustrating a method of opening the bottle 50 according to the second embodiment of the present invention, and thus, reference numerals are omitted except for parts necessary for the description as above. 3, 4A to 4D, 5A to 5D, 7A and 7C, 8A to 8C, 9A to 9C, 10, 11, 12A to 12C, 13 and 14. 15, as appropriate.

At this time, before the bottle cap 60 according to the second embodiment of the present invention also removes the sleeve 182, the bottle cap 50 may be unwound and unopened from the bottle inlet 54, and only after the sleeve 182 is removed. The sealing stopper 160 is rotated and separated from the discharge stopper 70.

Accordingly, when the sealing plug 160 is rotated and separated after the sleeve 182 is removed, the sealing plug 160 is in a state as shown in FIG. 16A. In particular, when the bottle 50 is erected as shown in the drawing, the inner plug 150 is discharged internally. The discharge hole 82 of the stopper 70 is blocked.

On the other hand, when the bottle 50 is tilted as shown in FIG. 16B, the inner stopper 150 is moved in the direction of the external discharge stopper 100 to open the discharge hole 82 of the internal discharge stopper, and the liquid in the bottle 50, and the like. May be discharged to the outside through the discharge hole 82 and the second discharge port 106. Therefore, it is impossible to re-inject the liquid into the erected bottle, so that counterfeit is impossible to replace the storage material inside the bottle 50, but only the discharge of the liquid stored in the bottle 50 shows an inherent anti-counterfeiting effect.

As described above, the bottle cap according to the present invention exhibits a feature that cannot be opened before the exact opening method is known, and greatly reduces the possibility of misuse or misuse of cognitive ability or misunderstanding and confusing the contents stored in the bottle. You can.

In addition, the bottle cap according to the present invention can be virtually impossible to falsify the opening of the seal according to the first opening, it is possible to ensure the reliability of the contents, and greatly reduce the possibility of unwanted contents leakage or air inflow through the middle plug or the inner plug, anti-counterfeiting It has the effect of further enhancing the function.
