BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a security and pouring stopper that includes a tubular channel which contains a ball and which has a radially outward chamber in which the ball may be partly contained, the ball being retained in the channel.
Different types of pouring stoppers designed for bottles are known which make it possible to close off the contents of the bottle when not pouring. Such pouring stoppers may be opened and closed manually by means of lids or the like.
An example of a pouring stopper is disclosed in U.S. Pat. No. 3,152,712. This pouring stopper--when the bottle is in a normal upright position, closes the outlet and thus hinders evaporation, etc. In an ordinary pouring situation, the ball is able to position itself in a circumferential and radially-outwardly arranged chamber. In this manner liquid may run through the chamber past the ball. The stopper disclosed makes it possible to close the outlet if the bottle is placed upside down. However, the stopper will not function as a security stopper hindering liquid discharge if a bottle is overturned.
Another example of a stopper of the type mentioned above is known from European patent application No. 264,181. According to this application the stopper consists of a ball positioned in a recess in a bottle neck. The ball may be pressed in tightening contact in the bottle neck and thus ensure that a high pressure is maintained in the bottle. When the bottle is to be emptied of its contents, a manual pressure is conveyed to the ball which is consequently pressed down into the bottle neck, which is provided with a circumferential and radially-outwardly arranged chamber in which the ball is received while the content of the bottle is being poured out. However, this construction gives no security against unintended discharge if the bottle is overturned.
It is the object of the present invention to provide a security and pouring stopper which will allow easy and effortless pouring when a container, preferably a bottle, is to be emptied of its contents in an ordinary way and which will at the same time block any discharge when the container is overturned unintentionally.
SUMMARY OF THE INVENTION
According to the present invention this is achieved with a stopper of the type mentioned above which is characterized in that the inside of the tubular channel has a circular cross section with a diameter which is only slightly larger than the diameter of the ball, and that the ball is retained in the tubular channel by means of a valve seat in either end of the channel, of which at least the valve seat at the outlet of the channel is annular, and that the radial chamber has a size which is substantially equivalent to the half of the ball size, and that the chamber is positioned immediately above the ball when, in a resting position in use, it will in contact against the valve seat situated next to the container on which the stopper is mounted.
As the radial chamber is not a circumferentially-extending annular chamber, the ball will with high certainty pass the chamber when, in case of overturning the bottle, it is thrown through the tubular channel. Even in case of a relatively slow fall the closure is obtained because the ball will only roll into the radial chamber when the latter is directed substantially downwards while overturning the container and when the "overturning" occurs as a slow overturning. If an initial slow overturning occurs, the ball may also roll into the radial chamber, but at increased speed of overturning before the container falls, the ball may be thrown back out of the chamber and ensure the closure.
During ordinary pouring the ball will, upon initial pouring, roll into and remain retained in the radially outward chamber. The stopper will preferably be asymmetric with a spout so that the user will always pour with the spout turning forward towards the glass, cup, etc., into which the content of the container is to be poured. In this manner particularly high certainty is obtained that the ball will alway
