Description

BOTTLE CAP FOR ADDING ADDITIVE

The present invention relates to an add-on bottle cap.

Generally, beverages are stored in a bottle, which consists of a tubular body with a closed bottom, a bottle neck protruding from the body and forming a bottle inlet, and a bottle cap opening and closing the bottle inlet. The bottle is formed of various materials depending on the article to be stored. Particularly, it is classified into glass, plastic, and ceramics according to the material thereof, and a glass bottle or a plastic bottle is mainly used as a beverage bottle. On the other hand, polyethylene terephthalate (PET) is widely used among plastics used in beverage bottles.

On the other hand, beverages are liquids for human consumption, and besides drinking water, there are various kinds of beverages, such as green tea, coffee, etc., carbonated beverages, fruit beverages, milk beverages and alcohol beverages. In recent years, health functional beverages with various raw material additives such as hinoki, bean sprouts extract, and vitamins mixed with water have been released and become popular with popularity.

Most of these beverages are produced in the factory by mixing raw materials with water and then supplied to consumers. Therefore, the consumer can not mix the raw material additive in accordance with the taste. Further, the raw material additive constituting the beverage is deteriorated, corrupted or discolored due to air temperature, ultraviolet rays, oxygen in the air enclosed in the bottle, etc., and thus the freshness can not be maintained for a long time. Therefore, a drink containing a raw material additive or the like has a short shelf life.

In order to solve such a problem, a bottle cap having an additive storage space has been devised as disclosed in the following patent documents. Such a bottle cap stores the additive therein, so that the consumer can easily mix the drink with the additive. However, the bottle cap having the conventional additive storage space ruptures the storage space with a pin, a blade or the like in a state where the bottle and the cap are combined, and the additive is discharged into the bottle. Therefore, such a bottle cap has a problem that the fragments generated when the storage space ruptures flows into the beverage bottle and contaminates the beverage. Further, since the ruptured storage space can not be sealed again, there is a problem that the amount of the additive to be mixed can not be controlled. In addition, when the additive is a liquid, when the liquid additive flows into the bottle already having a drink, the gas inside the bottle is not discharged to the outside, and the pressure inside the bottle rises. The pressure thus raised acts on the hole into which the additive is introduced into the bottle, which prevents the additive from flowing into the bottle, so that the additive remains in the bottle cap.

Accordingly, there is an urgent need for a solution to the problem of a bottle cap having a conventional additive storage space.

1 to 4, an additive feeding bottle cap according to an embodiment of the present invention is a hollow cylindrical shape that is screwed to the bottleneck 3 of the beverage bottle 1 and has an opening at the upper end 10 And a discharge hole 30 penetrating the lower surface 20 for discharging the additive 5 into the beverage bottle 1 and penetrating the side surface to allow the base 7 in the beverage bottle 1 to flow therein A main body 110 having a pressure regulating hole 40 formed therein and a receiving tube 120 protruding in a tubular shape toward the inside of the main body 110 from the lower surface 20 around the discharging hole 30 A cap 100 and a sidewall 213 screwed with the main body 110 and extending downward along the rim of the top 211 and a ceiling 211 covering the opening of the main body 110, One or more vent holes 215 are formed to penetrate the edge of the ceiling portion 211 and discharge the gas 7 introduced into the main body 110 to the outside And is inserted into the main body 110 through the opening of the main body 110 and is inserted into the receiving tube 120. The main body 110 is provided with an opening 210, And an opening / closing rod 250 protruded downward inside the receiving space 230 to be inserted into the discharge hole 30, the upper cap 250 including an opening / 200,

The vent hole 215 is in close contact with the upper end 10 of the main body 110 when the screw connection between the main body 110 and the plug 210 is locked, And is opened while being spaced apart from the upper end 10 of the main body 110 when the screw engagement is released.

The present invention relates to a bottle cap capable of accommodating an additive (5) and discharging the additive into the beverage bottle (1) to be mixed with the beverage (8) Respectively. Recently, various raw material additives are mixed into beverages in order to satisfy consumer's various taste. Such additives include various raw materials such as hinoki, bean sprouts extract, vitamins, and exist in powder or liquid form. Meanwhile, the additive 5 stored in the add-on bottle cap according to the present invention is also mixed with the beverage 8, regardless of whether it is powder or liquid. However, the add-on bottle cap according to the present invention is advantageous in that the additive (5) is discharged into the beverage bottle (1) while being coupled to the bottleneck (3) of the beverage bottle (1) , So that it is more effective when the additive (5) is liquid.

The lower cap 100 is coupled to the bottleneck 3 of the beverage bottle 1. The lower cap 100 includes a body 110 and a receiving tube 120 to be screwed with the upper cap 200 to receive the additive 5. [ . The main body 110 is formed in a hollow cylindrical shape having an opening in the upper end 10 and has a space therein. The discharge hole 30 is formed in the lower surface 20, 40 are formed. The lower surface 20 of the main body 110 faces the bottom of the beverage bottle 1 and the upper end 10 of the main body 110 is opposite to the lower surface 20 of the main body 110 it means.

The discharge hole 30 is formed through the lower surface 20 of the main body 110 so that the inside of the beverage bottle 1 and the internal space of the main body 110 communicate with each other. Therefore, the additive 5 accommodated in the lower cap 100 is discharged into the beverage bottle 1 through the discharge hole 30.

At this time, the lower surface 20 of the main body 110 may be formed in a conical shape so that the additive 5 is concentrated by the discharge hole 30. The lower surface 20 of the main body 110 is tapered so that the inner diameter of the lower surface 20 of the main body 110 is equal to the diameter of the discharge hole 30 It gradually gets smaller. Thus, the additive (5) is concentrated in the discharge hole (30) along the lower surface (20) of the inclined body (110).

The pressure adjusting hole 40 is also formed through the side surface of the main body 110 so that the inside of the beverage bottle 1 and the internal space of the main body 110 communicate with each other. The main body 110 is inserted into the bottleneck 3 by a certain depth and the pressure regulating hole 40 is formed on the side of the main body 110 portion inserted into the bottleneck 3. [ At this time, the outer circumferential surface of the main body 110 is spaced from the inner circumferential surface of the bottleneck 3 so that the pressure adjusting hole 40 is not in close contact with the inner circumferential surface of the bottleneck 3. Here, the pressure adjusting hole 40 allows the base 7 in the beverage bottle 1 to flow into the main body 110. Specifically, in the closed beverage bottle 1, not only the beverage 8 but also the gas 7 is filled. When the liquid additive 5 is introduced into the beverage bottle 1 in a sealed state, As the space occupied by the pressure becomes narrower, the pressure increases. That is, the pressure of the gas 7 increases as the volume of the gas 7 decreases. When the pressure in the beverage bottle 1 acts on the discharge hole 30, the discharge of the liquid additive 5 is hindered, (110), thereby preventing the pressure in the beverage bottle (1) from rising. At this time, one or more pressure adjusting holes 40 may be formed.

The receiving tube 120 is formed in a tubular shape in the inner space of the main body 110 so that the lower cap 100 is coupled with the upper cap 200 to receive the additive 5 therein. At this time, the additive 5 accommodated in the inside is discharged to the inside of the beverage bottle 1 through the discharge hole 30, so that the discharge tube 120 is connected to the discharge hole 30 from the lower surface 20 of the main body 110 As shown in Fig. The outer circumferential surface of the receiving tube 120 is formed to be spaced from the inner circumferential surface of the main body 110.

The lower cap 100 may include a cap 130 so that the main body 110 is screwed to the bottleneck 3 of the beverage bottle 1. [ The bottle cap 130 is formed by screwing the main body 110 and the bottleneck 3 such that the outer wall extends along the outer circumferential surface of the main body 110 to surround the bottleneck 3, So that it is screwed to the bottleneck 3.

Therefore, the add-on bottle cap according to the present invention can be used in combination with a conventional beverage bottle 1 having a screw thread in the bottleneck 3, so that it is not necessary to separately prepare the beverage bottle 1. [ In addition, by removing the screw-capped bottle cap from a commercially available bottled water bottle or the like and combining the add-on bottle cap according to the present invention, the additive 5 can be easily mixed with the bottled water.

The upper cap 200 is coupled to the lower cap 100 to discharge the accommodated additive 5 into the beverage bottle 1 and to discharge the gas 7 in the beverage bottle 1 to the outside, 210, a receptacle 230, and an opening / closing rod 250. [ The cap 210 covers the opening of the main body 110 and is screwed to the main body 110 of the lower cap 100 and includes a ceiling portion 211 and a side wall portion 213. At this time, the ceiling portion 211 is disposed at the upper end 10 of the main body 110 to cover the opening of the main body 110, and when the screw connection between the plug portion 210 and the main body 110 is released, And is spaced from the top 10. Meanwhile, the side wall portion 213 is formed to extend downward along the rim of the ceiling portion 211. Here, the downward direction refers to the bottom side of the beverage bottle 1 with respect to the ceiling portion 211. Accordingly, the side wall portion 213 is formed to have a space therein and to open the lower end thereof.

Since the stopper 210 is screwed to the main body 110, a thread is formed on the outer circumference of the main body 110 and a thread line corresponding to the thread of the main body 110 is formed on the stopper 210 as well. Specifically, the side wall portion 213 of the stopper 210 is formed into a hollow cylindrical shape, and a threaded portion may be provided on the inner peripheral surface thereof. The side wall portion 213 of the stopper portion 210 is screwed to the outer peripheral surface of the main body 110 while the main body 110 is inserted into the lower end of the stopper portion 210. [

One or more vent holes 215 are formed in the cap 210 so as to discharge the base 7 introduced into the main body 110 through the pressure adjusting hole 40 in the beverage bottle 1, . Here, the vent hole 215 is formed so as to pass through the edge of the ceiling portion 211 of the cap 210. The ceiling portion 211 is disposed at the upper end 10 of the main body 110 so as to cover the opening of the main body 110 when the ceiling portion 211 is in contact with the upper end 10 of the main body 110 . Accordingly, when the upper end 10 of the main body 110 and the ceiling portion 211 are in contact with each other, the upper end 10 of the main body 110 And is closed. Conversely, when the screw connection between the main body 110 and the stopper 210 is released, the ceiling portion 211 is separated from the main body 110, so that the vorthole 215 is opened.

As described above, when the liquid additive 5 is discharged into the sealed beverage bottle 1, the gas 7 in the beverage bottle 1 is regulated in pressure so that the pressure inside the beverage bottle 1 does not rise, And flows into the interior of the main body 110 through the holes 40. At this time, since the receiving tube 120 for receiving the additive 5 and the receiving stand 230 are connected to each other in the body 110, it is difficult to secure a space for accommodating the body 7. Therefore, even if a part of the base 7 inside the beverage bottle 1 is accommodated in the main body 110 through the pressure adjusting hole 40, the pressure inside the beverage bottle 1 rises, (30) and can interfere with the flow of the additive (5). However, the add-on bottle cap according to the present invention can prevent the pressure inside the beverage bottle 1 from rising because the gas 7 in the beverage bottle 1 is discharged to the outside by forming the vent hole 215 . Thus, the add-on bottle cap according to the present invention can secure a large space for accommodating the additive 5 in the main body 110 to accommodate a large amount of the additive 5, There is an advantage of smooth discharge.

On the other hand, one or more vault holes 215 are formed. The pressure generated in the beverage bottle 1 when the additive 5 is discharged into the beverage bottle 1 is controlled by the volume of the beverage bottle 1 and the main body 110, The diameter, the number and the like. Therefore, by regulating the number of the vent holes 215, the pressure inside the beverage bottle 1 is prevented from rising. Concretely, two or more bout holes 215 may be formed on the same circumference centered on the center of the ceiling portion 211. Here, the circumference refers to the circumference of a circle formed at a position where the upper end 10 of the main body 110 contacts with the main body 110 because the main body 110 is formed in a cylindrical shape. At this time, the two vent holes 215 may be formed to be symmetrical about the center of the circumference, that is, the center of the ceiling portion 211.

The receptacle 230 is formed inside the plug 210 and accommodates the additive 5 so that the receptacle 230 can be inserted into the plug 210 from the ceiling 211 of the plug 210, Respectively. Here, the receptacle 230 is inserted through the opening formed in the upper end 10 of the main body 110 and disposed inside the main body 110. At this time, the receptacle 230 is connected to the receiving tube 120 formed in the body 110 to receive the additive 5 therein. Therefore, the add-on bottle cap according to the present invention accommodates the additive (5) to be mixed with the beverage (8), so that the additive (5) can be easily stored. The additive 5 accommodated in the additive tapping cap according to the present invention is located inside the receptacle 230 connected to the receptacle 120 and the receptacle 230 and the receptacle 120 are located inside the body 110 So that it is not affected by external temperature and ultraviolet rays. That is, since the additive 5 is double protected from the external temperature and ultraviolet rays, there is no risk of deterioration, decay, discoloration, etc., and the freshness can be maintained for a long time. Therefore, the shelf life of the beverage 8 becomes long.

Meanwhile, the receiving tube 120 and the receiving part 230 should be connected to each other. Specifically, the receiving tube 120 may be inserted into and connected to the receiving table 230. That is, since the receiving tube 120 and the receiving table 230 are formed in the shape of a tube, the receiving tube 120 is received in the receiving table 230 such that the outer circumferential surface of the receiving tube 120 is in contact with the inner circumferential surface of the receiving table 230 . Conversely, the accommodating table 230 may be inserted into and connected to the receiving tube 120 (not shown). In any case, when the screw connection between the cap 210 and the main body 110 is released, the ceiling portion 211 rises in an upward direction, that is, in a direction opposite to the lower surface 20 of the main body 110, The tube 120 and the receiving table 230 should not be separated. Specifically, the length of the receiving tube 120 and the receiving space 230 is longer than the height at which the ceiling portion 211 rises.

The outer peripheral surface of the receiving part 230 is formed to be spaced apart from the inner peripheral surface of the main body 110, like the above-described receiving tube 120. When the receiving tube 120 and the receiving tube 230 are connected to each other, the receiving tube 120 and the receiving tube 120 are separated from each other by the inner circumferential surface of the main body 110 and have a space therebetween, The gas 7 in the beverage bottle 1 introduced through the pressure regulating hole 40 is accommodated.

On the other hand, the opening and closing rod 250 is inserted into the discharge hole 30 and formed in a bar shape protruding downward in the receiving space 230. Here, the downward direction refers to the bottom side of the beverage bottle 1 with respect to the ceiling portion 211. At this time, the opening / closing rod 250 may protrude from the ceiling portion 211 and may be fixed to a separate connector protruding from the inner circumferential surface of the receiving portion 230 (not shown). The opening and closing rod 250 is inserted into the discharge hole 30 to prevent the additive 5 from being discharged into the beverage bottle 1 when the screw connection between the stopper 210 and the main body 110 is locked. On the other hand, when the screw connection between the stopper 210 and the main body 110 is released, the opening / closing rod 250 is disengaged from the discharge hole 30, so that the additive 5 is discharged into the beverage bottle 1. At this time, when the opening and closing rod 250 is inserted into the discharge hole 30, the edge of the discharge hole 30 and the outer peripheral surface of the opening and closing rod 250 are closely contacted with each other, so that the additive 5 is not discharged into the beverage bottle 1 Do not. Therefore, since the additive 5 is discharged into the beverage bottle 1 without rupturing the storage space of the additive 5 according to the present invention, foreign matter such as debris, 1). Further, since the discharge hole 30 is opened and closed by screwing, the amount of the additive 5 discharged into the beverage bottle 1 can be easily controlled.

On the other hand, since the opening and closing rod 250 is forced into the discharge hole 30, the additive 5 does not leak. Therefore, the opening and closing rod 250 is formed of a material having a high hardness, and the body 110, in which the discharge hole 30 is formed, may be formed of a soft material. For example, the upper cap 200 is formed of polyethylene (PE) and the lower cap 100 is formed of polypropylene (PP) so that the opening / closing rod 250 is prevented from being inserted into the discharge hole 30 . However, the upper cap 200 and the lower cap 100 are not necessarily limited to these materials.

The thickness of the lower surface 20 of the main body 110 can be adjusted in order to close the discharge hole 30 so that the opening and closing rod 250 does not leak the additive 5. Specifically, if the area of the outer circumferential surface of the opening / closing rod 250 which is in close contact with the discharge hole 30 is wide, the opening / closing rod 250 can efficiently close the discharge hole 30. Since the discharge hole 30 is formed to penetrate the lower surface 20 of the main body 110 in the thickness direction, the area of the outer peripheral surface of the opening / closing rod 250, which is in close contact with the discharge hole 30, Is influenced by the thickness of the lower surface 20. Therefore, by adjusting the thickness of the lower surface 20 of the main body 110, the area of the outer circumferential surface of the opening / closing rod 250 which is in close contact with the discharge hole 30 can be sufficiently widened, ).

Meanwhile, the add-on bottle cap according to the present invention may include a discharge pipe 140 instead of forming the thickness of the lower surface 20 of the body 110 to be thick. Here, the discharge pipe 140 is formed in a tubular shape having an inner diameter equal to the diameter of the discharge hole 30. At this time, the discharge pipe 140 protrudes from the lower surface 20 of the main body 110 toward the outside of the main body 110 around the discharge hole 30. Therefore, even if the thickness of the lower surface 20 of the main body 110 is small, the outer circumferential surface of the opening and closing rod 250 is closely attached to the inner circumferential surface of the discharge pipe 140, thereby preventing the additive 5 from leaking from the discharge hole 30 can do.

Meanwhile, the add-on bottle cap according to the embodiment of the present invention may include a locking protrusion 50 and a locking protrusion 60 to prevent the upper cap 200 and the lower cap 100 from being separated from each other. Here, the locking protrusion 50 is formed protruding from the outer peripheral surface of the main body 110. The stopping protrusion 60 protrudes from the inner circumferential surface of the side wall 213 of the stopper 210 so that the stopper 210 can be unlocked when the stopper 210 and the main body 110 are screwed together. (See Fig. 5). Therefore, even if the threaded connection between the cap 210 and the main body 110 is released, the upper cap 200 is not separated from the lower cap 100.

Hereinafter, a method and an operation principle of an additive putter cap according to an embodiment of the present invention will be described in detail.

FIG. 5 is a cross-sectional view illustrating a process of discharging an additive in a bottle cap according to an embodiment of the present invention.

5, when the threaded connection between the cap 210 and the main body 110 is released, the additive 5 is discharged into the beverage bottle 1 , The base 7 in the beverage bottle 1 is discharged to the outside. Accordingly, in order to discharge the additive 5 into the beverage bottle 1 and mix it with the beverage 8 in the beverage bottle 1, the upper cap 200 is rotated to move between the stopper 210 and the main body 110 To be unscrewed. At this time, when the upper cap 200 moves upward, the opening / closing rod 250 and the cap 210 rise. Further, since the discharge hole 30 is opened by raising the opening / closing rod 250, the additive 5 is discharged into the beverage bottle 1. Meanwhile, when the stopper 210 rises and the ceiling 211 of the stopper 210 is separated from the upper end 10 of the main body 110, the vorthole 215 is opened. Therefore, when the additive 5 starts to be discharged into the beverage bottle 1, the base 7 in the beverage bottle 1 flows into the main body 110 through the pressure adjusting hole 40, And is discharged to the outside through the opening 215. As a result, the pressure inside the beverage bottle 1 does not rise, and the additive 5 is smoothly discharged into the beverage bottle 1 smoothly. At this time, if the screw connection between the cap 210 and the main body 110 is locked by rotating the upper cap 200, the opening / closing rod 250 closes the discharge hole 30, so that the amount of the additive 5 Can be adjusted. When the screw coupling between the cap 210 and the main body 110 is released, the locking protrusion 60 is caught by the locking protrusion 50 so that the upper cap 200 is not detached from the lower cap 100 .

6 to 7 are perspective views of an additive input bottle cap according to another embodiment of the present invention.

As shown in FIGS. 6 to 7, the add-on bottle cap according to another embodiment of the present invention may be used to prevent slippage when the upper cap 200 or the lower cap 100 is rotated to unlock or lock the screw A first concave and convex portion 217 and a second concave and convex portion 133. The first concave-convex portion 217 is a concavo-convex formed along the outer circumferential surface of the side wall portion 213 of the stopper portion 210. The second concavo-convex portion 133 is concavo-convex formed along the outer circumferential surface of the outer surface of the bottle cap portion 130. [

Meanwhile, the add-on bottle cap according to the present invention may include a first sleeve 218 and a first bridge unit 219 so as to confirm whether the drink is used from the outside. The first sleeve 218 is formed in a ring shape and is connected to the lower end of the side wall 213 of the stopper 210 while surrounding the outer circumferential surface of the main body 110. The first bridge portion 219 is a member for connecting the first sleeve 218 and the lower ends of the side wall portions 213. When the screw connection between the stopper portion 210 and the main body 110 is released, (218) and the side wall portion (213) are separated from each other. Accordingly, when the first sleeve 218 is separated from the stopper 210, it can be seen that the additive 5 has already been introduced into the beverage bottle 1. [

Meanwhile, the add-on bottle cap according to the present invention may include a second sleeve 135 and a second bridge 137 so that the beverage bottle 1 can be opened or closed. Here, the second sleeve 135 and the second bridge portion 137 are formed in the same shape and principle as those of the first sleeve 218 and the first bridge portion 219, respectively. The difference is that the second sleeve 135 surrounds the bottleneck 3 and the second bridge 137 is connected to the outer wall of the bottle cap 130. Similarly, if the second sleeve 135 is separated from the cap portion 130, it can be seen that the beverage bottle 1 has already been opened.

Meanwhile, the add-on bottle cap according to the present invention may include a sticker sheet 300 to prevent foreign matter from being caught in the vent hole 215. Here, the sticker sheet 300 is attached to the ceiling portion 211 of the stopper portion 210 to seal the vent hole 215. At this time, the sticker sheet 300 may display related matters such as components of the additive 5.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, It will be apparent to those skilled in the art that various modifications and variations can be made by those skilled in the art without departing from the scope of the present invention.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
