ADAPTER FOR BOTTLES
Technical Field
This device refers to the adapter, by means of which, bottles with fluid having on the opening a thread, are connected to devices for emptying fluids by means of earth gravitation.
According to the International Classification of Patents, the invention belongs to the following field of technique:
• B67D 3/00 - Apparatus or devices for controlling flow of fluids under gravity from storage containers for dispensing purposes.
Background Art
For hygienic and health reasons, it has been mass - used today worldwide industrially prepared and packed drinking water and other beverages. In order to facilitate a mass - use of beverages, it was developed the system for bottling, packing and consuming beverages. Beverages are packed in specially designed, returnable bottles with stoppers, enabling emptying their contents by means of special devices for fluids' emptying. The connection of a stopper and bottle is made without thread in the way, that the stopper seats tighly to the bottle neck opening. Fluids are bottled in bottling plant, when the stopper is changed. The construction solution of the system of stopper and bottle enables the use of standardized bottles with stoppers, adapted to only one type of bottle. Because of such a standardized way of closing bottles with stoppers without thread enabling emptying their contents on devices for fluids' emptying, it is not possible to attach other types of bottles with stoppers with thread. In the modern offer of finished beverages there is a series of beverages packed in bottles with volume of 1 up to 10 liters with screw-stoppers, which, because of the way of closing, can not be attached to the fluids' emptying devices.
The invention solves the technical problem of attaching bottles with beverages closed with screw-stoppers to devices for fluids' emptying. In practice there are no solutions enabling attaching bottles with beverages closed witth screw-stoppers to fluids' emptying devices.
By searching the patents in the base esp(5>cenet in the group B67D3 referreing to devices and appliances for management of fluids' flow from vessels because of
gravitation for the purpose of decanting, in the patent literature there were not found any solutions solving the mentioned technical problem. Disclosure of the Invention
Attaching bottles with beverages closed with screw stoppers to devices for fluids' decanting is solved by means of the adapter by which the bottle opening is connected to the device for fluids' decanting.
Adapter is the device, consisting of axial symmetrical hollow cylinder body on which one end there is made internal thread for accepting the bottle with thread and in the inner side there is a system for closing and opening the adapter and acceptance of the adapter to the decanting device.
The adapter is used in such a way, that the stopper is mannually unscrewed from the bottle and the adapter is screwed on. The bottle with the adapter is turned in such a way, that the adapter is below, whereby the cap of the adapter makes impossible flowing out the fluid from the adapter. The bottle with the adapter is placed on the distributor of the emptying device, whereby the distributor pushes out the stopper from the stopper's guide and opens the adapter. The fluid from the bottle flows out of the bottle from the emptying device. When lifting up partly or completely emptied bottle from the emptying device, the distributor pushes the stopper in the stopper's guide and in this way closes the adapter, which in this way could temporarily be used as a bottle stoppers.
Figure 1 shows the system of low adapter for bottle with high necks in cross section.
Figure 2 shows in cross section the system of high adapter for bottles with low necks. Figure 3 shows in cross section the adapter from the figure 2. screwed on the bottle opening, with the thread turned downward.
Figure 4 shows in cross section the adapter from the figure 2, screwed on the bottle opening with thread and placed on the emptying device. Both mentioned embodiments of a low and high adapter have the same construction.
Adapters shown on figures 1 and 2 consist of axial symmetrical hollow body on which one end there is the internal thread for acceptance of the bottle with thread
and in the inside there is a system for closing and opening the adapter and acceptance of the adapter to the decanting device.
The body 1 of the adapter has a form of hollow rotation symmetrical body, which generatrix is the straight line parallel to the axis of symmetry or curve of simple or complex form.
In the inside of one end of the body 1 there is the internal thread 2 which size and profile correspond to the external thread on the bottle opening to which the adapter is attached. The thread 2 ends with the notch in which it is inserted a flat ring sealing 3, laying on the level ring surface. Below the flat ring sealing 3, in the inside of the body 1 of the adapter, there is the structure for closing and opening the adapter and its acceptance to the decanting device. This structure consists of the guide 4, that is by means of a nut screwed in the body 1 , fastened to the body 1. The seat of the guide collar 4 and the body 1 makes the watertight connection. The stopper 6 in form of little glas with the bottom turned towards the sealing 3 is by tight seat pressed into the guide 4 with which it makes also the water tight connection. The opening of a stopper 6 ends with the collar 7 with the internal diametar less than the internal diameter of the hollow of the stopper 6. The adapter, mannually screwed on the opening of the bottle 8 is shown on figure 3. The front of the bottle neck 8 seats with the whole front surface on the flat ring sealing 3, making with it the watertight connection. The seat of the guide collar 4 and the body 1 , as well as the guide 4 and the stopper 6, also make watertight connections and the adapter screwed on the bottle opening 8 shown on fig. 3, functions as the bottle stopper 8, not allowing flowing out the fluid from the bottle 8, when the filled up bottle 8 with the adapter is turned upside down.
The filled up bottle 8 turned upside down with properly fastened adapter and closed system for closing and opening the adapter shown on figure 3 is placed on the decanting device according to figure 4. The decanting device 9 has the recess for accepting standardized bottle stoppers. According to the depth of the recess and the height of the bottle neck 8, the height of the adapter should be chosen in order to provide proper connection and stability of the bottle 8 with the adapter on the device 9.
The bottle 8 with the adapter is placed in the recess of the device 9, so that while lowering the bottle 8 with the adapter, the cylindric distributor 10 goes into the guide 4. While doing that, the top of the distributor 10 comes in the opening of the stopper 6, so that the flexible collar 7 of the stopper 6 jumps into the groove 11 on the top of the distributor 10. Through this temporary separable connection, the stopper 6 remains tied to the top of the distributor 10 also when the distributor 10 presses out the stopper 6 from the guide 4. Setting up is finished when the adapter with the top seats to the bottom of the recess. The distributor 10 makes with the guide 4 a watertight connection and the fluid may flow out of the bottle 8 only through the hole for fluid in the distributor 10, to which place the air is coming in through the hole for air in the distributor 10.
Fully or partly emptied bottle 8 with adapter, may be lifted from the device 9, whereby the remaining fluid shall not flow out of the bottle 8. In course of lifting the bottle 8 with the adapter, the guide 4 firstly covers the holes for fluid and air on the distributor 10 which draggs the stopper 6 in the guide 4 to the marginal position, when the collar of the stopper 6 seats on the guide 4, by which the adapter is fully closed and functions temporarily as the stopper of the bottle 8. In this way the manipulation of the adapter is boiling down to manual screwing and unscrewing from bottles without any special tools and without any special preparation of the adapter.
Body 1 and the nut 5 of the adapter, may be made of metal or non-metal materials and the sealing 3, guide 4 and the stopper 6 of flexible polymeric or elastomeric materials with good sealing characteristics. Adapter for bottles with threads together with the decanting device may be used in households, offices, catering objects and all other places where beverages are consumed. By its application the exploitability of bottles with beverages packed in bottles closed with screw-stoppers shall be extended and facilitated.
