Cap device for mixing different kinds of materials separately contained therein and in bottle

Abstract

A cap device for bottles allows an additive and a material to be separately stored in the cap device and a bottle, thus preventing the additive from being undesirably added to the bottled material. Furthermore, the cap device may contain a semisolid additive therein, as desired, thus allowing a user to mix the semisolid additive with the bottled material to prepare a mixture. The cap device has a cap body tightened to a mouth or an open lower end of the bottle, with an additive discharging means provided in the cap body to discharge the additive from a space inside the cap body into the bottle. The cap device further has a valve means for opening or closing the discharging means, according to a rotating action of the cap device relative to the bottle. The valve means includes a valve part which is brought into close contact with or spaced apart from the discharging means, thus closing or opening the discharging means to allow the additive to be discharged into the bottle to prepare the mixture. The valve means further includes a plurality of radial or vertical ribs which are integrated with the valve part into a single structure.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates, in general, to caps for bottles which contain therein a variety of materials, such as drinks, liquid medicines or liquid chemicals. More particularly, the present invention relates to a cap device for such bottles, which is capable of mixing an additive contained within the cap device with a bottled material to prepare a mixture according to a simple rotating action of the cap device relative to a bottle, thus allowing a user to easily prepare the mixture just before drinking or using the mixture. [0003] 2. Description of the Related Art [0004] In the related art, most of conventional disposable bottles circulated and sold in markets each contain therein only a single kind of material, such as a drink, a liquid medicine or a liquid chemical, and are closed by caps at mouths thereof. When a user wants to add an additive to the material contained in such a capped bottle so as to prepare ...

Benefits of technology

[0010] Accordingly, the present invention has been made keeping in mind the above problems occurring in the related art, for example, Korean Patent Application No. 10-2002-31470, and it is an aspect of the present invention to provide a cap device for bottles, which is capable of mixing an additive contained therein with a bottled material to prepare a mixture according to a simple rotating action of the cap device relative to a bottle, performed by a user, thereby allowing the user to easily prepare the mixture just before drinking or using the mixture.

[0011] It is another aspect of the present invention to provide a cap device for bottles, in which a valve means is stably placed at a desired position in a neck of the bottle, without being undesirably displaced.

[0012] It is a further aspect of the present invention to provide a cap device for bottles, which allows the additive and the material to be separately stored in the cap device and the bottle, respectively, such that the additive is prevented from being prematurely added to the bottled material.

[0013] It is still another aspect of the present invention to provide a cap device for bottles, which contains a semisolid additive therein, and allows a user to mix the semisolid additive with a bottled material to prepare a mixture by simply rotating the cap device relative to a bottle just before drinking or using the mixture.

[0018] Also, in another embodiment, the objects of this invention can be achieved by providing a cap device for bottles, comprising: a cap body tightened to an open lower end of a bottle through screw-type engagement, the cap body being opened at a lower end thereof, with a cylindrical space defined in the cap body and valve means provided in the cap body at an upper end of the cylindrical space; an additive container having a space to contain an additive therein, the additive container being received in the cylindrical space of the cap body, with a discharging opening provided on an upper end of the additive container to come in close contact with the valve means of the cap body, and a lower end of the additive container being opened and projected downward from the open lower end of the cap body; and a control unit having a cup shape which is closed at a bottom thereof, the control unit being assembled with the open lower end of the cap body to rotate relative to the cap body, with an internal thread provided on an inner circumferential surface of the control unit to be tightened to an outer circumferential surface of the lower end of the additive container through screw-type engagement, so that the control unit controls a vertical movement of the additive container.

Problems solved by technology

Therefore, it is necessary for manufacturers of the additives and the bottled materials to contain such additives and materials in separate containers and bottles prior to marketing them, thus undesirably wasting natural resources due to the production of the separate containers and capped bottles.

In addition, the adding of the additive from the separate container to the bottled material to mix them after removing the cap from the bottle is inconvenient to the user in that the user is forced to separately purchase and handle the additive container and the bottle.

Furthermore, it is extremely difficult for the user to add a precise amount of the additive from the separate container to the material contained in the bottle, and thus, the user roughly measures the amount of the additive to be added to the bottled material.

Therefore, in the case of mixing of an additive with a bottled drink to produce a mixed beverage, the rough measurement of the amount of the additive may result in change in taste and quality of the mixed beverage.

In the case of mixing of an additive with a bottled liquid medicine or a bottled liquid chemical to produce a mixed medicine or a mixed chemical, the rough measurement of the amount of the additive may result in incomplete dissolution of effective ingredients of the additive in the medicine or the chemical and a failure of accomplishment of desired medical or chemical effects of the mixed medicine or the mixed chemical.

However, the mixtures which are prepared by the manufacturers and marketed in the bottled state are problematic in that the effects of ingredients of the bottled mixtures may be gradually degraded as time goes by, in addition to change in colors of the mixtures.

Furthermore, the bottled mixtures may generate floating matters and deposit therein with passage of time.

However, since the outside ends of the above radial ribs are formed as free ends, the radial ribs may be easily bent or deformed.

Therefore, the valve means may be easily displaced in the neck of the bottle.
