Description:
BACKGROUND OF THE INVENTION 
     The present invention relates to an arrangement in connection with the retail sales of brewable products, such as coffee or similar products, comprising a grinder and a supply chamber for conveying coffee beans or similar to the grinder. 
     Formerly in the 1950s coffee was most often purchased as beans in packages of one quarter of a kilogram, and the shopkeeper ground the beans at the time of selling with a grinder provided in the shop. Such a retail method is, however, no longer used, but currently practically the only possibility is vacuum-packed light-roast coffee. 
     The packaging solution used today is, however, not the best possible from the environmental point of view, since as a result for instance in Finland annually nearly 4000 tons of waste is produced, and 1500 tons of this waste is laminate that is difficult to destroy. It is very likely that sooner or later attention will be paid to this drawback. Another drawback to the prior art technology is its limitedness, i.e. the fact that in practice only said light-roast coffee is available. A further disadvantage is that the coffee presently available no longer meets the requirements of the customer in every case, as customers are today quite often accustomed to fresh coffee which has a completely different taste and aroma from conventional vacuum-packed coffee. 
     SUMMARY 
     It is an object of the present invention to provide an arrangement wherewith the drawbacks of the previously used technology can be eliminated. This has been achieved with the arrangement of the invention, which is characterized in that the arrangement comprises at least one storage chamber for coffee beans or similar products, means for conveying coffee beans or similar products from the storage chamber to a supply chamber, and equipment for controlling the grinder to grind a predetermined quantity of coffee or similar products. 
     The primary advantage of the invention is that the quality of coffee improves, since the coffee can be vended fresh. Another advantage is significant savings in packaging material and the fact that laminates which are environmentally problematic are avoided. A further advantage is that a more realistic pricing policy for coffee can be implemented, which will make coffee trade more profitable than heretofore, and the customer will get value for his money. Furthermore, another advantage is that the introduction of novelties and special products is easier than heretofore, and thus the product selection available can advantageously be widened from the current selection.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     FIGS. 1-3 show a preferred embodiment of the arrangement of the invention. In the arrangement of the invention, a grinder is indicated at 1, and a supply chamber wherefrom coffee beans or similar products 3 are passed to the grinder 1 is indicated at 2, respectively. The grinder 1 may be of any type known in the art. 
     In accordance with the invention, the arrangement comprises at least one storage chamber 4 for coffee beans or similar products 3, means 5 for conveying coffee beans or similar products 3 from the storage chamber 4 to the supply chamber 2, and means for controlling the grinder 1 in such a way that it grinds only a predetermined quantity of coffee or similar products. The means wherewith the grinder 1 is controlled can comprise for instance a pre-settable time switch. The means wherewith coffee beans are conveyed from the storage chamber 4 to the supply chamber 2 can comprise for instance a screw conveyor. 
     The arrangement of FIGS. 1-3 operates in principle in the following way: Roasting houses deliver coffee to a shop in the form of freshly roasted beans in bags or economy-size bags. The shop has at least one arrangement as shown in the figures, comprising a storage chamber 4 for coffee beans, dimensioned according to the size of the shop, a grinder 1, and other possible accessories. The storage chamber 4 can be for instance a moving carriage located behind a door 8 that can be opened, as shown in the figures. The movements of the carriage are indicated by means of an arrow in FIG. 3. The coffee beans are passed from the storage chamber 4 to a supply chamber 2 for instance by means of a screw conveyor. The conveyance of the coffee beans 3 has been indicated by arrows in FIG. 3. The various components of the embodiment according to the figures are housed in a cabinet-like construction 9 made of plate elements. 
     The customer himself grinds the coffee with the grinder 1. The ground coffee runs into a bag or similar object which the customer himself has placed at the outlet of the grinder. The bag or similar object can be for instance a paper bag taken from a bag cartridge 6 mounted in the arrangement. For scales 7, which both weigh and price the ground coffee, can be disposed at the outlet of the grinder. The scales can naturally also be placed elsewhere. The grinder 1 can preferably be constructed as a device controlled by a time switch, i.e. a timer, and thus the grinder grinds a quantity of coffee pre-selected by the customer. The arrangement may for instance have two buttons, and when one of these is pressed the grinder grinds 250 g of coffee, and when the other is pressed the grinder grinds 500 g of coffee. The apparatus necessary for controlling the arrangement can be disposed for instance in an electronic unit 10. The main idea is that each customer will only grind the quantity of coffee he wants into a suitable package, and thus the freshness of the coffee can be guaranteed. 
     The embodiment set out above is in no way intended to restrict the invention, but the invention can be modified fully freely within the scope of the claims. It is thus evident that the arrangement of the invention or its details need not necessarily be exactly as set forth above, but also other solutions are possible. The front of the arrangement can be shaped fully freely, and thus the appearance shown in the figures is not the only possibility. The arrangement may be shaped for instance as a large coffee package, etc. In a shop, any number of arrangements can be installed; FIG. 4 shows one example. The example of the figures employs only one storage chamber for one grinder. This is however not the only possibility, but it is possible to use for instance two, three etc. storage chambers for one grinder. The storage chamber or storage chambers can also be fitted in a different location than the grinder or grinders. The arrangement can also be constructed to be such that the customer can himself make mixtures of different coffee varieties. The arrangement can then have for example 2 to 3 storage chambers and one grinder. Different varieties of coffee are disposed in the storage chamber, and the customer can make the mixture he desires by using the automatics of the arrangement. The arrangement can e.g. have an operating button at the push of which the grinder grinds a certain quantity of a desired variety of coffee, and another corresponding button for another variety, and so on. Instead of a screw conveyor, also other suitable means can be used as the means wherewith the coffee beans or similar products are conveyed to the supply chamber; examples of such are pneumatic conveyors, paddles in an endless chain or chord, etc. The operation of said means can be controlled for example with a level sensor disposed in the supply chamber, said sensor ensuring that too many beans are not transported to the supply chamber. The ground coffee may be supplied into the customer&#39;s own tin or similar object instead of a bag. Instead of the bags provided in the arrangement that are specifically designed for this purpose, conventional bags can naturally also be used. Furthermore, the invention is in no way restricted to coffee only, but it can also be implemented in connection with other corresponding products.
