Device for the dosed dispensing of paatous masses

The invention relates to a device for dispensing pasty masses, in particular pasty foods, with a container in which the pasty masses are stored and from which they can be expelled with pressure through an outlet valve are ο

There are very different impasto masses that are placed in containers Stocks are kept and can be taken out of the container in small portions if necessary industrial products such as greases. In the The food industry would also include fats, but also mayonnaise, tartar sauce, fish pastes, mustard and some other goods into consideration. The devices that have become known so far for the dosed dispensing of disastrous masses are mostly provided with elaborate filling mechanisms, which one Generally, purchasing these devices will not make them portable for the individual consumer. On the other hand, would be in the house hold, to which a larger number of people belong, devices of the type mentioned can be used with advantage.

009830/0939

The object of the invention is to provide a device for dispensing vent to create pasty masses that are simply structured and yet meet all requirements «,

The object is achieved in a device of the type mentioned in that, according to the invention in the container, which is held in a support frame, an expulsion piston is displaceable and that the outlet valve, which is designed to be self-closing, opens automatically at a certain pressure exerted on the mass.

By attaching the container belonging to the device and receiving the pasty masses on a support frame, it becomes possible to tap these pasty masses now below the container when the expulsion piston on the mass in the Container acts «The self-closing outlet valve, which only opens under the pressure exerted, is extremely simple be constructed and is also extremely unsusceptible to repairs

According to a further embodiment of the invention serves as a Container an upright cylinder, the expulsion piston with a push rod acting on it in the axial direction is provided, which protrudes through the cylinder cover to the outside. The on the pasty mass in the container interior exerted pressure thus acts vertically and directly in the direction of the outlet valve. The vertical printing direction is furthermore advantageous, since the direction of pressure from above is particularly favorable for the operator's hand. Advantage-

009830/0939

It is also liable that the protruding far from the device Push rod formed a level indicator

According to a further embodiment of the invention the outlet valve consists of a cap-shaped, formed from an elastic synthetic material part, which is provided in its top region with a Easiermesserschnitt _o This exhaust valve closes, because of the tendency of the elastic plastic in its starting shaping back, always by itself, and never leaves such a large gap that pastose masses may still flow in. In order to open the slit, a certain pressure must always be built up, the pasty mass pressing into the easing knife cut and opening it up a little.

It has proven to be particularly favorable if the lower cover area of the outlet valve is conical and the razor cut is tangential to the side of the cone tip. The inflowing pressure in the outlet valve pasty mass thus acts namely with force components which are directed at an acute angle to the printing component laterally outwardly _o The opening of the razor slit is thus considerably facilitated.

In the case of pasty foods in particular, it is important that these are cooled in the container and are thus protected from spoilage for a longer period of time. This cooling can be with the The device according to the invention can be brought about in a particularly simple manner in that the container is arranged in an outer container,

-4- 009830/0939

the wall of which consists of a heat-insulating material, with the Sohubstab and the outlet valve through the outer container reach through. This outer container with its heat-insulating wall is suitable for a cooled one To keep pasty mass cool for a long time · Especially However, it is favorable if, according to a further development of the invention, the cavity between the container and the outer container with is filled with a refrigerant. This refrigerant can, for example, be ice · However, it is also possible to use a liquid to be used which is cooled by means of a separate cooling unit »Through the additional use of a refrigerant can also put particularly perishable foods such as fish pastes at the prescribed temperatures from about 1.5 to 4.5 ° C.

According to a further advantageous embodiment of the invention, the container cover is removable and also serves as Lid for the pasty mass receiving container. The push rods are then guided through the cover of the outer container, which for thermal reasons also expediently consists of a heat-insulating material or at least it is provided with a heat-insulating layer. By assembling the container cover and The lid of the container holding the pasty masses makes it very easy to refill the device.

According to a further embodiment of the invention, the Umbe-Jialter provided with a drain valve. Through this drain valve

009830/0939

can be refrigerant or water after use or for the In the event of a renewal, it can be drained without affecting the operation of the device.

According to a further advantageous embodiment of the invention, the push rod is pierced and the bore runs into the Valve chamber of a non-return valve, which when actuated the push rod is closed in the pressure direction. The hole serves as a pressure equalization channel when lifting the Expulsion piston over the push rod. If the push rod is raised, this would result in a cavity in the lower container a negative pressure, which would make lifting the piston very difficult. ”However, the non-return valve opens the lower one Cavity of the container when the piston is raised to the bore and thus to the atmosphere, then a negative pressure cannot arise form and the piston can be easily pulled up.

The device can already be used with a single container for holding pasty masses. However, it is recommended to use in to accommodate several, for example four to six, containers for different types of pasty masses next to each other in an outer container, in order to meet all needs.

If several pasty-containing containers are arranged in an outer container, then it is also advantageous if the Support frame is rotatable on a platform around the central point of the device. The device can then be in the middle of a Tiaohea can be arranged and every person or guest can

-6- 009830/0939

the container with the paatöaen mass to turn, which he needs at the moment »

Finally, to facilitate transport, a handle is also provided, which is expediently designed to be pivotable so that it can be folded back.

The .Erfindung is shown on the basis of the drawing Embodiment explained in more detail «, It show:

Pig. 1 the device according to the invention partly in side view and partly in section ^¥,

Fig. 2 the formation of a% itil insert,

3 shows the design of the exhaust valve,

Fig. 4 is a plan view of the device naoh the invention,

The device for dispensing pasty masses consists of a container 1 which is arranged on a support frame 3. The omb container 1 is made of a heat-insulating material, which is insensitive to impact on its outside Mass is coated. Ss is, however, also possible, the outer container, which has a pot-shaped shape, from one To draw metal, for example aluminum, and then coat it on its inside with a heat-insulating compound. A foamable plastic, for example, can be used as the coating compound.

The Traggestill consists of three or four pillars which are attached their upper part means a screw connection 9 or the like.

-7- 009830/0939

are attached to the outer container 1, while the lower ends 11 be fixed on a foot 13. This foot 13 is in turn arranged on a platform 15 on which it is by means of a spherical ring (not shown) is supported. Thus, the container 1 is supported by a standing surface (not shown), for example a table top, kept at a distance and can be turned into any position »

To transport the device according to the invention, a handle 17 is arranged on the container 1. The fastening links of the handle 17 on the container 1 are designed as pivot bearings, with which the handle 17 _f can be folded back as long as it is not needed.

A cover 21, which is provided with a central handle 23, is used to close the wrapper 1. Either the cover 21 itself is made of a heat-insulated material, or it is also provided with a heat-insulating layer which can be sprayed onto its inside or which is filled into a cavity _{or the like}

In the example shown, four containers 25 are arranged in the outer container 1, in which different pasty containers Masses can be filled. This pasty mass receiving container 25 are cylindrical and around a vertical central axis 27 distributed around. The containers 25 stand upright in the outer container 1. In order to achieve good heat transfer to the cavity of the Umbehalters, the Container 25 made of a material with good heat transfer, for example

-8- 009830/0939

wise stainless steel, formed. However, if a good heat transfer is undesirable, the containers also made of plastic.

An expulsion piston 29 is arranged in each container 25 The expulsion piston 29 can be displaced in the vertical direction, for which purpose it is attached to a push rod 31 which protrudes through an opening 33 in the cover 21 at the top of the device. The length of the push rod 31 is dimensioned so that the P upper end of the push rod has not yet penetrated the cover 21 is when the expulsion piston is already in contact with the bottom 35 of the container 25.

In the expulsion piston 29, a cavity 37 is provided, which is open to the lower piston surface 39 and thus with the Cylinder cavity below the ejector piston is in communication · Furthermore, in the push rod 31 is a central bore 41, which extends almost to the upper end 43 of the push rod 31 and then over a transverse channel 45 is led outside. Inside the cavity 37 in the piston 29 there is a valve ball 47 which, when pressed down the push rod 31 closes the bore 41 (Pig · 1, left container) and only releases it when the push rod 41 after is pulled up (Fig. 2 * right container),

While the push rod is being pushed down, the container is equipped with a pasty mass filled. Usually these are pasty Masses extremely sensitive to ingress of air. If now the valve ball 47 when pressing down the push rod 31 and the

_9_

009830/0939

Piston 29 closes the bore 41, then, when the container is ^{full, no atmospheric air can penetrate into the I 1} UlI space, the pasty masses filled in are thus completely sealed off from the outside air and, as far as possible, against spoilage

The cavity 50 between the outer container 1 and the individual Container 25 can be filled with ice. This means that the mass inside the container is at a low temperature coolable, which extends its shelf life * A disadvantage of using ice, however, is that this has to be refilled frequently »Refilling is not a problem, since a drain valve 51 for molten water is provided on the bottom side 49 of the container. It however, the lid 21 must be lifted to refill with ice and small pieces of ice must still be beaten are introduced into the cavity 50.

It is much cheaper if the cavity 50 is filled with a refrigerant when the device is used for a longer period of time, brought to the desired low temperature by a cooling unit, not shown, and at this temperature is held.

The outlet valve 53 shown in FIG. 2 is arranged on the bottom side 35 of the container 25. This outlet valve consists of a thimble-like, cap-shaped injection molded plastic part 55 which is provided with a sealing tube 57 on its open hand. The sealing flange

-10-009830 / 0939

57 is inserted into a socket 59 of the bottom 49 of the outer container 1. An expression 61 in the socket 59 ensures a tight fit; of thimble type plastic part 55 *

The cover area 63 of the thimble-like part 55 made of plastic is conical. The side of the conical tip 65 is in this case a tangentially led Rasienaesserschnitt 67, which is closed when the in the container 25 mass by means of the piston 29 is not pressed _o However, once the mass _ under within the container 25 by the piston 29 Pressure is set, the pressure rises in the cap-shaped part 55 of the outlet valve 53 and the razor cut widens to one. Gap through which the pasty mass can flow out of the container 25 downwards. A container arranged below the outlet valve 53 can then receive the flowing pasty mass. As soon as the pressure on the head 43 of the push rod 41 ceases, the gap 47 formed by the razor cut closes and the pasty mass is again protected against germs or the like and enclosed in the container

The pasty mass arranged in the container 25 is then, if it is a perishable food mass, properly secured against the ingress of germs, and especially if it is additionally cooled from the outside from the space 50, for longer periods Time Stored in the container 25 against spoilage.

In Pig. 4 * illustrated embodiment of the invention four individual containers 25 are arranged distributed around the central axis 27. From the lid 21 of the container 1 protrude the push rods 31 out, with the help of which the expulsion piston 29 can be pushed into the cylinder 25. In this case, the support bracket 17 lies against the outer wall 69 of the outer container so that it does not interfere with the use of the device »The fastening means 9 for the support rods 5 are indicated in Fig. 4 by screws. In addition, FIG. 4 shows the central button 23 for lifting off the cover 21 from its top.
