Definitions
- the invention relates to a method of expressing flowable paste-like substances, particularly foodstuffs, disposed in containers using a conventional cartridge-expressing tool as well as to a reusable cartridge body usable for said purpose .
- the expressing tool has a substantially trough- shaped storage space, into which the container holding the substance to be expressed is inserted.
- the container is generally a cartridge with an advanceable piston which is driven forward from one end of the cartridge to the other by means of an operating device of the tool, a plate of the operating device being applied against the piston and driving it forward until the cartridge is empty. The plate fastened to a rod is then retracted, whereupon the empty cartridge is removed and has to be disposed of.
- a fixed spout element is usually attached or attachable to the other end of the cartridge. The amount of waste is extremely high.
- manufacture of the cartridges is quite expensive. Particularly when the flowable paste- like substance is a foodstuff, the manufacturing costs are very high because the entire cartridge has to be made of materials which are suitable for said purpose. Recycling of the empty cartridges is practically impossible .
- the expressing tool moreover has to be of a corresponding design and requires very frequent cleaning.
- the design of the operating device may vary depending on whether by means of a uniform stroke movement possibly the entire contents of the cartridge are to be expressed or whether, as is generally the case with foodstuffs, a quite specific predetermined quantity, one portion, is to be dispensed upon operation of the operating device.
- Operating devices of said type are known as such and are not the subject matter of the present invention.
- the non-recyclable waste quantity i.e. the amount of the residual waste which is soiled
- a special tool having a similar operating device has been developed which, instead of a trough-shaped storage space, uses a hollow cylinder which is firmly attached to one end of the operating device and is open at the other end.
- the bag With the plate retracted, the bag is inserted through said open end in such a way that its spout portion projects outwards.
- a cover then has to be put on and securely fastened, e.g. by means of a screw or bayonet joint, only the spout portion projecting through said cover and being openable by cutting or tearing at said point.
- the object of the present invention is to indicate a procedure whereby original costs are reduced, handling is very simple, the waste quantity is reduced and also the risk of soiling is reduced.
- the invention proceeds from the basic idea of inserting the bags known per se, provided they are- sealed, into reusable cartridge bodies which in turn are insertable into conventional cartridge-expressing tools.
- Exchange in the course of continuous operation, e.g. of a fast food restaurant, is extremely simple.
- the removal and disposal of empty bags and the insertion of full bags into such reusable cartridge bodies may be effected when business is slack, at the close of business or before the start of business under stress-free conditions, with the added result that the risk of soiling is very much reduced.
- it is at most the reusable cartridge body or parts thereof which may become soiled, the expressing tool itself, which as already mentioned is very difficult to clean, being unaffected thereby.

- Fig. 10 the section B-B through a part of the piston plate element according to Fig. 9.
- Fig. 1 shows a conventional cartridge-expressing tool 1, into which is inserted a reusable cartridge body 2 according to the invention having a flexible bag 3 inserted therein.
- a trough-like cartridge storage space 4 substantially comprises a part-cylinder portion, the longitudinal extension of which is such that a reusable cartridge body 2 is insertable from the open side.
- a front wall 5 is provided with a central opening 6 or a differently shaped, e.g. V-shaped, opening, through which the spout portion described farther below may be introduced.
- the cartridge storage space 4 is firmly connected to an operating device 7.
- the operating device 7 comprises an internal mechanism (not shown in detail) which, upon operation, moves a rod 8 in the direction of the front wall 5 of the cartridge storage space 4.
- the rod 8 carries at its end directed towards the front wall 5 a plate 9 and at its other end a transversely directed draw lever 10, by means of which manual retraction of the rod 8 is possible.
- the operating device 7 further carries a fixed handle 11 and a pivotally supported operating lever 12. When the operating lever 12 is operated by swivelling towards the handle 11, the operating device 7 is activated in such a way that the rod 8 with its plate 9 is moved in the direction of the front wall 5.
- the general requirement is to dispense a precisely defined quantity of the foodstuff - one portion - each time the operating lever 12 is operated, for which reason the operating device 7 is designed in such a way that upon operation of the operating lever 12 the rod 8 travels a predetermined distance which is such that only the required portion is expressed. It is customary for the necessary force to be triggered by the action of a spring, such a spring being placed under the required initial tension by using the draw lever 10 to pull the rod 8 into its most retracted position.
- the reusable cartridge body 2 comprises a plurality of parts which are described in detail further below, namely a hollow body 14 in the form of an elongate hollow cylinder, a piston plate element 15 disposed displaceably in the hollow body 14 and an annular spout-carrying element 16 which is insertable at one end of the hollow body.
- a flexible, outwardly sealed bag 3 containing a paste-like, flowable substance, particularly a foodstuff such as, in particular, a sauce, it being perfectly possible for the sauce to contain diced solid particles (relish) such as is the case with, for example, remoulade sauce.
- a sauce particularly a foodstuff such as, in particular, a sauce
- diced solid particles such as is the case with, for example, remoulade sauce.
- Other examples of sauces of said type are semi-solid foods, mustard, pickles and supplementary sauces such as ketchup.
- the bag 3 shown more clearly in Fig. 2 is made of an advantageously transparent plastic film which is suitable and permitted for the relevant substance, this being of particular importance especially for foodstuffs.
- Folding over and welding along a longitudinal seam 18 initially produces a substantially tubular portion.
- a spout portion 19 is formed, i.e. a portion tapering gradually and ultimately to a greater extent from the edges, namely the fold 20 on the one hand and the longitudinal seam 18 on the other hand, is closed off likewise by welding, the end situated at the extreme left in Fig. 2 being welded a plurality of times in order to achieve a specific mechanical strength.
- a tearing or cutting line 21 is moreover also provided in a conventional manner in said region such that it is possible without a high mechanical effort to tear or cut along said tearing line 21 and open the extreme left end of the hollow space in the bag 3, and indeed such that the torn-off portion, diagrammatically denoted by 22, may contain as little as possible of the contents of the bag 3.
- the bag 3 is then filled in a known manner from the other - in Fig. 2, extreme right - end and welded shut by means of a transverse seam 23. Prior to tearing along the tearing line 21, the substance such as a foodstuff is therefore sealed tightly and hygienically in a bag 3.
- the volume of the bag 3 is determined in such a way that it never exceeds the available volume inside the reusable cartridge body 2.
- the hollow body 14 shown in Fig. 3 has at its one end - on the right in Fig. 3 - an edge 25 leaving free an opening, through which - cf . Fig. 1 - the plate 9 may safely enter and come to rest against the piston plate element 15.
- the edge 25 is, on the other hand, so dimensioned that said piston plate element 15 may come to rest against it .
- the hollow body 14 has an initial bevel 26 and an annular groove 27, which are important for the insertion of the spout -carrying element 16.
- the hollow body 14 is advantageously made of a high-strength material, in particular a plastic material, which is suitable for the substance such as the foodstuff.
- said element comprises two portions, namely an outer ring 29 and an inner piston part 30.
- the ring is made of a low-friction material, in particular of a low- friction plastic material, and/or is, in the manner shown, provided at the outside with as little surface area as possible in contact with the inner wall of the hollow body 14, e.g. by means of a rear bead 31 and a front lip part 32 which in each case come into substantially annular contact with the inside of the hollow body 14, in the manner indicated by a dashed line.
- the axial longitudinal dimension of the ring 29 is such that there is no risk of canting of the piston plate element 15.
- the piston part 30 is firmly or releasably latched into the ring 29 in a manner which is only diagrammatically illustrated.
- said piston part at its rear is designed, e.g. by means of radial webs 33 and an annular web 34, in such a way that the plate 9 of the tool 1 may be reliably applied against and reliably move the entire piston plate element 15 in a forward direction.
- the piston part 30 At its end directed towards the inside of the reusable cartridge body 2, the piston part 30 has a lug 35, the shape of the shoulder 36 of the lug 35 substantially corresponding to the shape of the spout portion 19 of the bag 3 (Fig. 2) .
- the two-part construction has the advantage that, where necessary, a piston part 30 with a differently shaped lug 35 may be inserted and, in the event of excessive wear, the ring 29 may likewise be separately exchanged.
- a one-part construction such as is indicated in Fig. 1 is also conceivable.
- the edge region of said piston plate element 15, formed in the embodiment according to Fig. 4 by the lip part 32, is designed so as to reliably prevent parts of the bag 3, e.g. in particular the transverse seam 23 or the longitudinal seam 18, from jamming between the inner wall of the hollow body 14 and the piston plate element 15.
- the longitudinal dimensions of the piston part 30 and the ring 29 may differ, in which case the latching of the piston part 30 in the ring 29 may be axially variable.
- the piston part 30 upon relief of the pressure exerted by the plate 9 may itself relieve its pressure upon the bag 3, thereby preventing undesirable dribbling from the open spout portion 19 of the bag 3.
- the spout-carrying element 16 is of a substantially annular construction having a circular central opening 38 and an outer supporting ring 39 for application against the front end of the hollow body 14 remote from the operating device 7.
- the central opening 38 widens from its front end, which during operation is remote from the operating device 7, via a shoulder 40, the shape of which corresponds on the one hand to the shape of the spout portion 19 of the bag 3 but also on the other hand to the shape of the shoulder 36 of the piston part 30.
- the effect achievable thereby is that the lug 35 together with the shoulder 36 penetrates into the spout portion 19 and therefore almost totally expresses the bag 3 so that the foodstuff introduced into the bag 3 may be virtually completely used up.
- an annular bead 41 which is used for latching into the annular groove 27 of the hollow body 14.
- the substantially annular spout- carrying element 16 comprises two semi-circular parts 42 and 43 which, in the region of the supporting ring 39, are firmly but pivotally connected to one another at one point by means of a hinge element 44.
- hinge elements are, in the case of plastic parts, known in principle and may comprise merely a weakening at the appropriate point .
- An insert in the form of a tear-resistant elastic band may also be provided.
- an engagement guide is provided which, in the embodiment, is formed by a tongue-like projection 45 on the one semi-circular part 42, which may engage into a corresponding recess 46 in the other semi-circular part 43.
- the recess 46 may extend substantially over the entire periphery except for the point at which the projection 45 is provided.
- the gap 47 and the central opening 38 are so dimensioned that they may embrace the spout portion 19 of the bag 3, including the substantially plane welded portions which border the spout filled with foodstuff.
- the tongue-and-groove engagement between annular bead 41 of the spout-carrying element 16 and annular groove 27 of the hollow body 14 has to be merely good enough for said engagement to hold even when the spout-carrying element 16 is loaded by the weight of a completely full bag. Even slight vibration should still be tolerable. This is sufficient because, while in use, the reusable cartridge body 2 is supported via the spout - carrying element 16 against the front wall 5 of the tool 1.
- the spout -carrying element 16 also is preferably made of a plastic material which is permitted for the substance such as the foodstuff.
- the hollow body 14 contains inside it the axially displaceable piston plate element 15 initially in a random axial position. The user then inserts a bag 3 inside the hollow body 14 so that, on the one hand, the piston element 15 is displaced until it is applied against the edge 25 and, on the other hand, the user merely has to ensure that the spout portion 19 points outwards. As soon as the user has substantially inserted the bag 3, the spout -carrying element 16 with the two semi- circular parts 42, 43 hinged open is grasped.
- the two semi-circular parts are then fitted together, the projection 45 engaging into the recess 46, the central opening 38 coming to lie around the spout portion 19 and the welded portions which border the spout portion 19 being situated in the gap 47, it being quite possible for the boundary walls of the gap 47 to be loosely applied against the welded parts.
- the user then presses the spout-carrying element 16 towards the hollow body 14 until the annular bead 41 latches into the annular groove 27.
- the reusable cartridge body 2 then has a closed bag 3 and may be introduced in the usual manner into the cartridge- expressing tool 1 by inserting it into the cartridge storage space 4.
- the front end of the spout portion 19 then projects not only from the reusable cartridge body 2 but also in a forward direction through the central opening 6 of the front wall 5 of the tool 1.
- the plate 9 of the operating device 7 is then moved until it is applied against the opposing surface of the piston plate element 15, here the piston part 30.
- the bag 3 is opened by tearing off the portion 22 along the tearing line 21. Each time the operating device 7 is operated, an appropriate quantity of the substance such as the foodstuff is expressed from the bag 3 through the open spout portion 19.
- the lug 35 of the piston plate element 15 penetrates into the spout portion 19 of the bag 3, which in turn is applied once more against the shoulder 40 of the spout -carrying element 16, so that the substance such as the foodstuff in the bag 3 is, in the course of a further stroke motion, expressed almost totally from the bag 3.
- the rod 8 and hence the plate 9 are retracted (in Fig. 1, to the right) by means of the draw lever 10 until the plate 9 has moved once more out of the reusable cartridge body 2.
- the reusable cartridge body 2 is removed in the usual manner from the tool 1.
- the spout-carrying element 16 is then pulled back out of the hollow body 14, the emptied and compressed bag 3 remaining attached to said spout -carrying element 16 and being very easily disposable.
- the hollow body 14 with the piston plate element 15 of the reusable cartridge body 2 contained therein is once more ready to be filled with another fresh bag 3.
- a plurality of reusable cartridge bodies 2 may be filled with full bags 3 when business is slack, before the start of business and/or after the close of business and that, with such reusable cartridge bodies 2, the emptied bags 3 may be removed during the same quiet periods of business. Costly cleaning processes are necessary at most routinely after extended periods and by no means every time a bag 3 has been emptied.
- the hollow bodies 14 may be marked differently, e.g. by different colouring, when different substances, especially foodstuffs, are to be used in a business. Even though the projecting length of the portion of the rod 8 carrying the draw lever 10 is an indication of the state of emptiness of a bag 3, it is also conceivable to make the hollow body 14 entirely or partially transparent .
- the spout -carrying element 16a shown in Figs. 7 and 8 has substantially the same function and also substantially the same construction as the spout-carrying element 16 according to Figs. 5 and 6. Comparable elements are therefore provided with the same reference character, to which the letter a is added. A more detailed explanation is therefore not provided.
- the insertion into the cartridge body corresponds to a clamping-in. This may be enough when the initial tension achieved in the joint 44a is sufficient to prevent the bag, as a result of the operation of the expressing tool, being pressed so strongly against the spout -carrying element that the latter might be released from the cartridge body 14.
- the name of a manufacturer or distributor to be imprinted or embossed by injection moulding so that it is outwardly visible.
- the important feature of the embodiment according to Figs. 7 and 8 is that disposed in the central opening 38a in an extension of the gap 47a are two opposing surface elements 48 and 50 which are pressed towards one another under spring bias .
- the spring bias is achieved in the embodiment by V-shaped strips 49 and 51 which are formed both on the surface element 48, 50 and on the associated semi-circular part 42a, 43a.
- the spring bias exerted by the strips 49 and 51 upon the surface elements 48 and 50 is such that, when there is a spout portion 19 (Fig. 2) inserted between the surface elements 48 and 50, the surface elements 48 and 50 compress said spout portion 19 in such a way that, even when the bag 3 is open, its contents cannot escape unless the expressing tool 1 is operated.
- the spring bias is achieved by the formed-on V-shaped strips 49 and 51.
- the spring bias is however also achievable in another way, e.g. by providing an actual spring. If, however, the spout-carrying element is manufactured as a plastic injection-moulded part, it is advantageous to form the surface elements 48, 50 and the strips 49, 51 achieving the spring bias as integral parts thereof . It is perfectly possible for the construction (not shown in detail) to be such that the distance between the two surface elements 48, 50 does not necessarily correspond to the size of the gap 47a, it even being possible for the two surface elements 48 and 50 to lie adjacent to one another when there is no bag inserted.
- a two-part piston plate element 15 was described with reference to Fig. 4 which makes it possible, upon relief of the pressure exerted by the expressing tool 1 upon the piston plate element 15, for the piston part 30 to be movable at least slightly relative to the ring 29 to relieve the pressure upon the bag 3.
- FIG. 9 Another embodiment is described with reference to Figs. 9 and 10, in which a one-part piston plate element 15a is illustrated.
- a state is shown, in which there is no bag inserted in the cartridge body 14 and by means of the expressing tool 7 the piston plate element 15a has been applied against a spout -carrying element 16b, which may have one of the forms of construction according to the previous drawings but may however alternatively have a different configuration, which is not shown in detail, if this is appropriate for the application in question.
- a spout -carrying element 16b which may have one of the forms of construction according to the previous drawings but may however alternatively have a different configuration, which is not shown in detail, if this is appropriate for the application in question.
- Clearly visible, however, is the applied state of the two shoulders which was described further above.
- the piston plate element 15a firstly comprises a ring part 54, the outside of which is designed for sliding contact with the inside of the cartridge body 14. Projecting internally from the shoulder 36a towards the edge 25 of the cartridge body are, firstly, a contact arrangement 55 and, secondly, web 56.
- the webs 56 especially serve as elements to be applied against the surface of a plate 9 of the expressing tool 1.
- the substantially annular contact arrangement 55 is specially designed to cooperate with the plate 9 of the expressing tool 1 in such a way that a firm but releasable connection is achieved between the plate 9, and hence the expressing tool 1, and the contact arrangement 55, and hence the piston plate element 15a, such that a backward movement of the rod 8 and hence of the plate 9 effected by the operating device 7 and the piston plate element 15a is driven backwards. It is therefore possible to achieve reliable relief of the pressure upon the bag 3 (not shown) , thereby further reducing the risk of dripping.
- Such an arrangement is suitable particularly when the expressing tool 1 is operating according to a so-called step-back process, whereby upon operation of the operating lever 12 towards the handle 11 there is firstly forward travel by a preset amount and upon release of the operating lever 12 a slight backward motion effecting such a pressure relief is caused before further forward travel is initiated by renewed operation of the operating lever 12.
- a procedure is advantageous for dispensing a substance, especially foodstuffs, in portions.
- Such a device is prior art and has been developed by the company, Alfred Fischbach KG of D-51766 Engelsmaschinen.
- Such a firm but releasable connection between the plate 9 and the contact arrangement 55 may be effected, for example, by a tongue-and-groove engagement (not shown in detail) .
- the plate 9 is not circular but approximately oval, a circle with the diameter do circumscribing the largest transverse dimension and a circle with the diameter di describing the smallest transverse dimension.
- the contact arrangement 55 has an annular, thin-walled portion 58 which, in the embodiment, carries two opposing projections 57 on the portion directed towards the edge 25 of the cartridge body 14.
- the inside diameter of the thin wall 58 is slightly greater than the diameter do.
- the distance between the projections 57 is smaller than said diameter do but greater than the diameter di .
- the plate 9 in one of its positions may be introduced past the projections 57 in a contact-free manner into the cylindrical cavity defined by the thin wall 58.
- the plate 9 in said position is then rotated, in the embodiment, by 90°, it is then, upon each backward motion of the plate 9, applied against the projections 57 and therefore drives the entire piston plate element 15a backwards.
- Said rotation may be effected by rotating the draw lever 10.
- Release of the engagement between the plate 9 and the piston plate element 15a is effected in an identical manner. This is effected automatically when, after emptying of the bag 3, the expressing tool is to be returned into its starting position, which is effected by rotating the rod 9 by means of the draw lever 10 and pulling backwards on said draw lever 10.
- an opening 59 is provided instead of a lug 35 (Fig. 4) an opening 59 is provided. Said opening may be used to receive an exchangeable lug element (not shown in detail) . It is, of course, also possible to provide a piston plate element 15 which carries a lug 35.
- the portions may be dispensed more accurately, which cannot be guaranteed to the same extent when there is mobility between piston part 30 and ring 29.
- the portion of the thin wall 58 carrying the projection 57 may also be separated by slots from the remaining wall portions so as to produce a snap- in effect upon introduction of the plate 9, irrespective of the latter' s position.
- the arrangement may also be such that, during the backward motion of the plate 9, the piston plate element 15a is fully driven and only at the end of said backward motion as a result of application against the web 25 and of further backward motion of the plate 9 is such a high force exerted that the engagement is released. The basic principle of the firm but releasable coupling is therefore not abandoned.
