Hand-held device for the extraction and metered dispensing of fruit juices

The invention relates to a hand-held device for the extraction and metered dispensing of fruit juices, in particular of Citrus fruit consisting of one over part of it Length with a screw thread and radial juice inlets provided at both ends open Fruchtanbohrohr, one arranged at one end of the Fruchtanbohrrohres Pressure surface for the fruit and a juice collecting container, whereby the free end of the Fruchtanbohrrohres with e'.ner axially directed spur gearing is provided.

Hand implements for obtaining juice from citrus fruits, which consist essentially of a Fruchtaabonrrohr, are known from a variety of references, examples, the <DE-PS 153 or 66o of the FR-PS 1 1o3 217th In both

In some cases, the hand-held device consists of a one-piece, with:

radial openings and threaded fruit; Drill pipe, which can be inserted or screwed into the fruit and in this state serves as a conduit for the juice squeezed out of the fruit. In which ; The fruit tapping tube according to FH-PS 1 1o3 317 is on the end of the fruit tapping tube that penetrates into Ϊ the fruit:

In addition, a cutting device projecting radially beyond the tapping pipe is provided for comminuting the pulp. \ The juicing of the fruit takes place here regularly by manually squeezing the fruit so that the juice of the \ fruit flesh through its radial openings into the fruit |

to be led. These known devices for obtaining fruit juices, in particular from citrus fruits, allow the instant obtained by squeezing the fruit Pour juice over the tapping tube, whereby the design of the openings of the Fruchtanbohrrohres counteracts a certain sieve effect allows parts of the pulp to be carried along in the juice. In another known handheld device for extracting juice from Citrus fruits (DT-AS 1 26o 715) is through the Fruchtanbohrrohr formed according to a tube circumference arranged spring knives, which can be pierced into the fruit and is also ma lower end of this Fruchtanbohrrohres formed by a penknife a fruit pressure plate is provided, to which a centrally disordered juice drainage pipe is connected. The fruit juice production takes place in the same way by pressing the litrus fruit together, the knife blades forming the tapping tube are compressed against the force of their spring action and by shredding the flesh a greater fruit juice yield should provide. According to some of the embodiments of the essentially to the formation of the tapping pipe as DE-AS 1 260 715 aligned with resilient knife blades is the Fruchtanbohrrohr instead of a pressure plate as an open Downstream of the shell formed juice collecting container. All these known institutions have in common that the to juicing citrus fruit drilled using the tapping tube hsw. is pierced over the greater part of its thickness and the Juice squeezed out of the pulp partly through the tapping tube or partly through the knife blades that form it Drain pipe or the like. Be fed, so that on the one hand Side only the appropriate amount of juice can be obtained from the fruit for the respective pressure applied and on the On the other hand, due to the applied pressure, there is always a certain amount of juice squeezed out of the peel, which under today's conditions always a certain amount of chemical preservatives, as they are usually added afterwards be splashed or sprayed onto the fruit, and either rinsed with the juice obtained from the pulp or by running along the surface of the juice to be juiced Fruit is mixed with the juice obtained from the pure pulp. Since it can be assumed that citrus fruits

regardless of the origin, generally with a health hazard Preservatives are sprayed on before they are dispatched or sold, in principle it is It does not matter how the juice exiting through the pores of the peel of the citrus fruit mixes with it The juice obtained from the pure pulp combines in every case with the rinsing of preservatives In the juice intended for human consumption is undesirable.

Another disadvantage of the known hand-held devices for gev / irnen Of citrus fruit juice consists in that rte have no juice storage facility, as jeveils the proportion of juice corresponding to the pressure exerted on the citrus fruit flows out through the tapping pipe. The amount of juice corresponding to the pressure exerted on the citrus fruit, however, is very large The extent depends on whether it is a freshly drilled fruit or whether the fruit has already been squeezed out several times has been. As a result, the normal user can also use such a handheld device to obtain the desired amount of juice »Dose the light exactly, especially since he usually has no knowledge of whether it is a freshly drilled one Or fruit that has already been squeezed several times. this Is particularly important where such hand-held devices are used for subsequent seasoning of dishes, for example fish or meat can be used. Also for the individual preparation of salad or the like Such handheld devices are used to give the respective guest the opportunity to personalize the To give the salad a taste.

A hand-held device for obtaining dosed results results from the above-mentioned conditions Dispensing fruit juices, in particular citrus fruits, create BU, which makes it possible to obtain the fruit juice from the citrus fruit on the one hand, and on the other hand eu in stock, so that it can be dispensed in dosed quantities regardless of the state of the fruit's expression can. A device that meets these claims in general

7807238 23.1178

fulfilled is known from US Pat. No. 3,073,237. In this known device one with a PruchtanpreSteller combined tapping pipe, which has lateral juice inlet openings, is provided, and is provided by a juice discharge pipe, which on the one hand with a juice storage container and on the other hand with a pouring opening connected, interspersed. The juice discharge pipe is axially displaceable within the tapping pipe and can be put together be pushed through the citrus fruit with the storage container, so that a pouring opening at its free end can be attached, through which the juice obtained is dispensed in dosed quantities. This well-known Hand-held device is characterized in particular by the fact that it consists of a large number of individual parts, the assembly of which makes a considerable effort required. Furthermore, this known handheld device offers no guarantee that The juice escaping from the peel does not mix with the juice of the pure fruit pulp is mixed, so that in the fruit juice intended for human consumption also from the fruit peel rinsed juice parts containing highly toxic preservatives are introduced.

Based on this state of the art, the invention is based on the object of creating a handheld device that can be operated with one hand in particular for obtaining and, above all, dosed dispensing of fruit juice, especially the juice of citrus fruits, which on the one hand consists of the smallest possible number of components and in automatic machines, preferably of die-cast or plastic can be produced, on the other hand, an optimum amount of juice exclusively from the pulp of a citrus fruit, as well as a metered outputting allows obtaining a subset of the obtained juice or juice depleted and that finally the V _e nneidung a mixing of the pulp juice with the exiting during the pressing of the fruit, preservatives pulping peel juice permitted. A further object of the invention is to create a device which allows the hand-held device inserted into a fruit to be parked with an at least partially filled juice collecting container.

7807238 2 3T1? .78

According to the invention, this object is essentially achieved in that a One-piece juice collection container and for the fruit tapping tube is connected coaxially aligned. The fruit collection container is essentially cylindrical, while the Fruchtanbohrrohr widens conically towards the collecting container and in the transition area to the juice collecting container has a screw thread with a large pitch and which has only one turn. Combined with the arrangement of a pouring spout on the juice collection container and the use of the opening of the juice collection container Closing lid, the hand-held device according to the invention enables all the known hand-held devices similar disadvantages to avoid. First of all, the one-piece construction of Fruchtanbohrrohr allows and juice collecting container the simplest form of hand-held device that can be produced on machines for extracting juice from citrus fruits, the arrangement of a juice collecting container at the same time Dosed dispensing of the fruit juice obtained in each case, regardless of the state of squeezing of the fruit. Since the conical design of the tapping pipe creates a sealing effect between the fruit peel and the tapping pipe, through which the juice obtained from the pure pulp can flow into the collecting container, is achieved, is also any mixing of the peel juice that occurs when the fruit is pressed together with the for human consumption excluded certain juice. According to another feature of the invention in The transition area between the tapping pipe and the juice collecting container provided radial collar is still prevented, that escaping from the fruit peel with preservatives mixed juice with that from the pure pulp can mix the juice obtained.

According to a further embodiment of the invention it can be provided that the juice collecting container at its free end side can be closed by means of a hinged lid and further that in the transition area

7807238 11/23/78

A fruit pressure plate can be placed between the tapping pipe and the juice collection container.

Finally Κμ-η-η further be provided that the handheld device is a storage device associated with that allows sam ¹ · been drilled citrus fruit on a fish or the like to turn off the handset., Without the risk that the partially-filled juice collecting container runs out. This is achieved according to the invention in that the hand-held device is assigned a storage tray, which can preferably be designed as a mirror image of a Fruchtanpreßeller and is provided with a storage surface or a storage edge, which enables the non-tilting storage of a citrus fruit provided with a hand-held device according to the invention. The storage tray can also have the shape of a well-known egg cup and, in addition to a receiving tray for the citrus fruit, have a lower tray forming a stable support surface.

A particular advantage of the device according to the invention is seen in the fact that it is made in an injection molding process Made of both metal and plastic material can be made, one made of plastic material Device of this type is provided with a chrome plating.

Further advantageous individual embodiments of the invention emerge from the further subclaims.

The invention is in the following example description described in detail with reference to an embodiment shown in the drawing. In the drawing shows the

FIG. 3 shows a side view of a hand-held device according to the invention provided with a fruit pressing plate ;

Figure 4 is a sectional view of an inventive Hand-held device according to Figures 1 ″ to 3 together with a parking device assigned to it.

A Saftsaaamel container is integral and coaxial with the tapping pipe 1 2 trained. The juice collection container 2 is essentially cylindrical, while the tapping pipe 1 based on its connection to the juice collector EU is tapered towards its free end. The tapping pipe has a g-rigi at its free end directed spur toothing 3, in the area of which it is tapered in terms of its wall thickness in such a way that it forms a kind of cutting edge 4. The tapping pipe 1 is still in its area adjacent to the juice sasamel container 2 provided with an outwardly voting screw thread 5 having only a pin thread. The Screw thread 5 has a large pitch so that it can easily be screwed into the fruit to be juiced. Γα his between the screw thread 5 and the face gear 3 is the fruit tapping tube 1 provided with large, oval juice inlet openings 6 arranged opposite one another. The side walls 7 the juice inlet openings 6 are beveled tangentially to the longitudinal axis of the tapping pipe 1, so that their outer Edges 6 act as cutting edges. In the transition area between the tapping pipe 1 and the juice collecting container 2 is one of the largest diameter of the Fruchtanbohrrohres 1 compared to an enlarged diameter Cylinder surface 9 arranged, which to the circumference of the Fruchtaübohrrohres 1 drops off in a steeply inclined surface 1o. The cylinder surface 9, which directly to a radially projecting collar 11 adjoins, serves to aof the hand-held device unfolds a fruit pressure plate 12. The FruchtanpreSteller 12 has a general conical cross-sectional shape and is in its central

7807238- ₂ l Tl 78

Area provided with a recess, via which it can be pushed onto the cylinder surface 9 with a resilient extension of its recess edges. The fruit pressure plate 12 is therefore attached to the hand-held device according to the invention by being clipped onto the cylinder surface 9. The radial collar 11 is, however, designed so that the use of a Pruchtanpreßeller is not absolutely necessary for the use of the handheld device according to the invention, but also the radially protruding collar 11 serves as a repellent surface for the peel juice emerging from the peel of the fruit and mixed with a chemical preservative. The conicity of the Fruchtanbohrrohres 1 causes on the enen side a sealing contact of the fruit peel 13 on the fully inserted tapping pipe 1 and on the other hand the creation of a cavity between the core 14 of the drilled fruit and the inner circumferential surfaces 15 of the tapping pipe, through which the by pressing the fruit pulp juice obtained from the citrus fruit can flow out without washing around the surfaces 16 of the fruit kernel encompassed by the tapping tube 1 more than necessary. The gaps 17 created between the drill core and the drill pipe as a result of the conicity of the tapping pipe 1 are completely sufficient to allow the juice obtained as a whole from the pulp of the citrus fruit to flow into the fruit juice collecting container 2. As can be seen in particular from the representations of FIGS. 2 and 3, the fruit juice collecting container 2 is provided on its peripheral surface with a large number of flattened surfaces 18 which serve as a handle and facilitate the piercing or screwing of the tapping tube 1 into the citrus fruit. On its inner circumference 19, the juice collecting container has an essentially smooth-surfaced cylindrical wall. In this case, VqTm, in the interest of a simplified production, can also be provided that the conicity of the attachment tube 1 continues into the juice collecting container 2. The juice collecting container 2 is provided with a pouring spout 2o, as can be seen in particular from FIGS. 1, 2 and 3. In connection

with a top end 21 of the juice collecting container overlapping, closable cover 22 is thus a supply and metered output of the depending on the Ausepreßstatus the citrus fruit 25 guaranteed from this extractable juice.

The hand-held device according to the invention is essentially used for seasoning fish, meat or salads with larger ones Tables or in inns, where it is necessary on the one hand, the respective dishes by adding To season or re-season juice from citrus fruits and on the other hand is necessary, a series on top of one another follow the guests an opportunity for individual seasoning of food and must therefore be able to be placed on the table in such a way that in whole or in part filled juice container does not contain juice can leak unintentionally. Experience has shown that a hinged lid prevents leaks in the storage container can not completely prevent accumulated juice, is provided according to a further feature of the invention, that the hand-held device is assigned a storage tray 24, which is initially a mirror image in its shape can be formed for the Fruchtanpresseller 12. In the embodiment shown, the tray however, it is essentially in the form of an egg cup and has, in addition to one, one side of the fruit Shell 25 a shelf 26. Of course, can the shell 25 also in the manner obtained per se with a tilt-proof placement of the with an inventive Hand tool provided citrus fruit guaranteeing contact surface or a corresponding contact edge be provided. As can be seen in particular from the representations of FIGS. 1 and 2, the inventive One-piece hand-held device in an injection molding process made of both plastic and metal, preferably Aluminum are produced, especially in view of the fact that the assignment of a Fruchtanpresseller as a result of the Use of a radial collar 11 is not absolutely necessary. If the hand according to the invention is used from one against the attack "for example from citric acid
