    The present invention relates to a valve device intended to allow discharge of a product (2), preferably a liquid or semi-liquid food product, such as for instance ketchup, mustard, dressing or a beverage, from a container (3). The valve device (1) has at least two valves (6-8) of elastic material, which are closed when they are in the original positions (C) and by means of pressure are expandable to tensioned positions (B), in which they are open to release product (2). The valves (6,7,8) are individually arranged on a diaphragm (5) of elastic material, which by means of pressure is expandable from an original position (A) to a stretched position (B). When both the diaphragm (5) and the valves (6,7,8) assume their original positions (A, C), all valves (6,7,8) have contact with at least one support part (15), which prevents them from opening, for to prevent air from passing through the valves (6,7,8) to the inside of the existing product (2). (Figure 2).

    Description of a preferred device according to the invention.
    The vent device 1 shown in the drawings is intended to allow discharge of a product 2, preferably a liquid or semi-liquid food product, such as for example ketchup, mustard, dressing or a beverage, from a container 3. This is preferably airtightly closed and is preferably capable of collapsing product 2 is fed out of the same. The discharge of the product 2 from the container 3 can take place with some type of discharge device 4, but the discharge can alternatively take place by squeezing the container 2 by hand or with some aid (not shown).
    The valve device 1 has a membrane of elastically resilient and resilient material and assumes in a normal shape an original position A (shown in solid line in Figure 2). By being pressurized from the inside in a direction L in which discharge of product 2 takes place, the diaphragm 5 can be caused to assume a stretched position B (shown in broken lines in Figure 2), in which it bulges out in said discharge direction L. When said pressure actuation in the discharge direction L ceases, the diaphragm 5 automatically returns to its original position A due to its resilient ability. In this, the diaphragm 5 can be flat or substantially flat and in its stretched position B it can bulge out in the discharge direction L and be substantially bald or domed.
    The diaphragm 5 has a plurality, preferably three valves 6, 7 and 8, each of which consists of or has diaphragm parts 9, which preferably form parts of the diaphragm 5 and which are resiliently resilient and resilient, which means that each valve 6-8 also has these characteristics. Each membrane part 9, i.e. each valve 6-8, has an annular and substantially circular outer part 10 and an inner part 11 arranged inside it with two or more intersecting slots 12,13, which pass through the membrane material. Each outer part 10 can function as a roller diaphragm, i.e. has a roller function, which allows the valve 6-8 to change position from an original position C (shown in solid lines in Figure 2) to a stretched position D (shown in broken lines in figure 2). This is accomplished by subjecting each valve 6-8 to said pressure in the discharge direction L and when it is caused to assume its tensioned position D the inner part 11 has been stretched and the slots 12,13 are open and can release product 2. When said pressure ceases rolls the outer part 10 back, meaning that each valve 6-8 automatically returns to its original position C and then the diaphragm parts 9 close the slots 12,13 and thus the valve 6-8 in question.
    The diaphragm portion 9, which forms the outer portion 10 of each valve 6-8 and has a roller function, may be thinner than the diaphragm portion 9, which forms the inner portion 11.
    In addition, the membrane parts 9 can be thinner than the membrane 5 in general.
    Valves 6-8 are preferably designed to be opened only when the diaphragm 5 has assumed its tensioned position, i.e. bulges out, which means that the valves 6-8 assume positions in which they can emit product 2 in diverging outflow directions 2a-2c.
    Thus, the valves 6-8 in said positions are obliquely outwardly directed in relation to an imaginary line E directed axially through the valve device 1 so that the three outflow directioners 2a, 2b and 2c diverge in relation to said line E and to each other. In this way, the product will be able to be portioned out, in this case, three different places 17a, 17b and 17c on, for example, a dish 17.
    Because the valves 6-8 are preferably arranged symmetrically in relation to each other and at one and the same distance to the line E, product can be discharged in advantageous directions.
    In addition, the valves 6-8 are preferably substantially identical in design, which means that each valve at each dispensing occasion can dispense the same amount of product 2 as the second valve or valves.
    When, after discharge of product 2, negative pressure arises in the discharge device 4 (and / or, where applicable, in the container 3), the valves 6-8 must not open when they assume their original positions C, as they would then let air into the not yet discharged parts of the product 2. This is prevented by at least one support part 15 which, seen in the discharge direction L, is arranged inside the valves 6-8 and their inner parts 11 provided with the slots 12, 13 so that they have contact with the support part 15, which due to this contact prevents the slots 12, 13 from opening, i.e. thus prevents the valves 6-8 from opening when they are in their original positions C.
    The discharge device 4 can have a hose part 22 of elastically resilient material. This hose part 22 can be arranged in a pipe part 23 (indicated in figure 1 by dashed lines) with a movable discharge means 24. The hose part 22 can be connectable to the container 3 through a coupling device 25 or vice versa. There may be a non-return valve 26 which prevents product 2 contained in the hose part 22 from passing back from it into the container 3 when product 2 in the hose part 22 is subjected to pressure.
    To discharge product 2, the discharge member 24 is pushed in, which means that the hose part 22 is compressed and product 2 is pushed out of this and the valve device 1.
    When releasing the dispensing means 24, the hose part 22 will regain its original shape and thereby return the dispensing means 24 to its initial position and at the same time product 2 will be sucked from the container 3 into it.
    The valve device described above can be used in connection with a coupling device 25, which can have an outer, tubular coupling part 27 and an inner coupling part 28 arranged in the container 3. These coupling parts 27,28 can be connected to each other by pressing holes in container 3 with the outer coupling part 27 and then inserting it into the inner coupling part 28 and pressing the coupling parts 27,28 together. Because the outer coupling part 27 is tubular, it is achieved that product 2 can flow from the container 3 through it to the hose part 22.
    The object of the invention is not limited to the above-mentioned embodiments, but it may vary within the scope of the appended claims. Thus, it can be mentioned that the membrane 5 and the membrane parts 9 included therein, which form the valves 6-8, can be formed in one piece of the same material, for example silicone.
    In addition, the membrane 5 can be formed in one piece with and in the same material as a cylindrical part 16, which can be exchangeably arranged on the discharge device 4, for example on the support part 15. Optionally, the membrane 5 can be arranged on the part 16 as a gable side at this. The support part 15 can be arranged in a part of the discharge device 4.
    Finally, it can be mentioned that the product 2 may be of a different type than those mentioned, in which it is important that the valves cannot open to suck in air through them.
