Abstract

Un tuyau (5) de transport d'un liquide pompe par une pompe (3), sert en particulier a transporter une boisson dans un appareil de distribution des boissons allant d'un conteneur de boissons (4) vers un robinet (6). Dans certaines applications de transport d'un milieu liquide, des differences de pression se produisent parfois dans le milieu, et elles provoquent des eclaboussures et des pertes a l'extremite du tuyau cote robinet. La presente invention a pour objet d'eliminer cet inconvenient en prevoyant un tuyau (5) ayant une portion (5a) dont la section est plus grande que celle des autres portions, et dont les parois sont plus epaisses que celles des autres portions du tuyau.A pipe (5) for transporting a liquid pumped by a pump (3) is used in particular for transporting a drink in a beverage dispensing apparatus going from a beverage container (4) to a tap (6). In some applications of transport of a liquid medium, pressure differences sometimes occur in the medium, and they cause splashes and losses at the end of the hose on the tap side. The object of the present invention is to eliminate this drawback by providing a pipe (5) having a portion (5a) whose section is larger than that of the other portions, and whose walls are thicker than those of the other portions of the pipe. .

Description

Hose
This invention relates to a hose for transport of a liquid medium, especially drink in a drink server, from a drink package to a tapping cock.
At transport of drink through a hose in a drink server pressure differences will easily arise, which are not balanced until the drink leaves the hose, and cause splashes and wastage in connection with the drink being tapped into a glass or the like.
It is the object of the present invention to provide a hose where the pressure differences in the liquid medium are balanced before this reaches the outlet end of the hose. In this way a more quiet and even flow of the liquid medium is obtained when this leaves the hose.
The object indicated above is realized by using a hose which has been given the characteristic features defined in the following claims.
An illustrative example of the invention will be described below with reference to the enclosed drawings, where Figs. 1 and 2 show schematically a drink server, in which the hose of the invention is intended to be used, and Fig. 3 shows a hose of the invention partly in section.
The drink server 1 shown in Fig. 1 comprises a space 2, which contains a pump unit 3 in the form of a so-called hose pump, which operates according to a so-called peristaltic principle.
In the space 2 a drink package, 4, e.g. with a volume of 20 litres, is also disposed.
A hose 5 extends from the package 4, via the pump unit 3 to a tapping cock 6 placed on top of the space 2, which cock comprises a pivotable arm 7, to which the glass is pressed to activate the pump unit 3.
It is more evident from Fig. 2 how the hose 5 is arranged in the tapping cock 6.
The hose 5 is not exchanged as soon as a package 4 is empty, but it is replaced at least once a day for hygienic reasons.
In Fig. 3 an illustrative example of a hose according to the invention is shown which, thus, is intended to be used as the hose 5 in Figs. 1 and 2. As is evident from Fig. 3 the hose 5 shows a portion 5a with an enlarged cross section. This enlarged cross section has been obtained by making the walls of the hose 5 thinner.
Due to the fact that the walls of the hose have been made thinner this portion 5a will be more leastic and, consequently, balances more easily possible pressure difference of the drink flowing through the hose 5.
In the illustrative example according to Figs. 1 and 2 the hose 5 is approximately 1800 mm long. It is then suitable that the widened portion 5a is disposed between the pump unit 3 and the outlet of the hose 5. The length of the widened portion 5a can preferably amount to at least about 1/5 of the length of the hose after the pump unit 3.
It has been found to be expecially advantageous if the hose 5 has a portion 6b with a normal cross section, calculated from its outlet opening, this portion preferably having a length of about 300 mm. The portion 5a with a widened cross section and a length of about 200 mm will then follow.
The hose 5 terminates in a portion 5c with a normal cross section and a length of about 1300 mm. Thus this section 5c will pass through the pump unit 3.
By using the hose described above instead of a hose with a constant cross section along the whole of its length a substantially more quiet outflow of the drink through the outlet end of the hose is obtained. As a consequence of this the risk of splashes and wastage at tapping of the drink into a glass will be reduced.
The invention is by no means restricted to the illustrative example described above but can be freely varied within the scope of the following claims. Thus, it is possible within the scope of the present invention to vary the counterpressure in the hose after its widened portion 5a by arranging a restriction of some kind in the portion of the hose designated by 5b, i.e. between the widened portion 5a of the hose and its outlet end.

Claims

Patent Claims
1. A hose (5) for transport of a liquid medium conveyed by a pump unit, especially for transport of drink in a drink server (1) from a drink package (4) to a tap (6), in which the pump unit is disposed between the package and the tap, characterized in that it has a portion (5a) with a widened cross section relative to the other portions (5b, 5c) of the hose (5), the portion (5a) with the widened cross section having thinner walls than the other portions (5b,5c) of the hose (5).
2. The hose of claim 1, characterized in that the portion (5a) with a widened cross section is located between the pump unit and the outlet opening of the hose (5).
3. The hose of claim 1 or 2, characterized in that the length of the widened portion (5a) is about 1/5 of the length of the hose (5) after the pump unit.
4. The hose of any of the preceding claims, characterized in that the cross sectional area of the widened portion (5a) is 2-3 times larger than the cross sectional area of the other portions (5a, 5c) of the hose (5). - - - -
