The present invention relates to an apparatus for assembling a packaging combination including a tubular casing and a dispensing device according to claim 1. The present invention further relates to a method for assembling said packaging combination according to independent claim 12. Moreover, the present invention relates to a packaging combination for accommodating and dispensing a viscous or granular filling material according to claim 16 as well as to a dispensing device according to claim 22 for being attached to a tubular casing and a partially filled tubular casing according to claim 23 to which a dispensing device may be attached.
From EP patent application 1 988 032, a tubular or sausage-shaped packaging is known, being filled with sausage meat. The sausage-shaped product is produced by closing a tubular casing at one end, filling the sausage meat into said tubular casing and closing the filled tubular casing at its respective other end. In order to allow an easier opening of the sausage-shaped product, perforation lines including a number of weak locations are provided on the casing, along which the casing may be opened by pulling off the casing material and dispensing the sausage meat.
Furthermore, packing combinations including a tubular casing packing and a dispensing device are known, e.g. from German laid open document 38 31 225, wherein a device for dispensing the filling material stored in a tubular or bag-shaped packing is disclosed. The device includes a rigid tube having a dispensing nozzle at its one end and being provided for containing completely a bag-shaped casing. The bag-shaped casing containing a pasty filling material, like an adhesive, has to be opened at one end and has then to be positioned in said rigid tube with its opened end facing the dispensing nozzle. A piston matching the inner diameter of the tube is thereafter pushed into the tube, thereby squeezing the bag-shaped packaging and dispensing the filling material through the dispensing nozzle.
With this known packaging combination, it is of disadvantage that the rigid tube has outer circumferential dimensions being such that the complete bag-shaped casing can be accommodated in said rigid tube. If this known packaging combination is provided as a disposable device, this solution is expensive due to the big rigid tube being made from relatively expensive plastics. If this known packaging combination used such that only bag-shaped casing is thrown away and the rigid tube is used several times, the bag-shaped casing must be opened outside the tube so that, when the opened bag-shaped casing is introduced in the rigid tube, filling material can accidently discharged and can pollute the environment.
The assembling of said known tubular casing and dispensing device to a packaging combination on one hand is cost and time expensive, since said assembling has to be made by hand. Moreover, in case that the dispensing device has to be reused, it has to be cleaned from the filling material, which comes into contact at least with the dispensing nozzle. On the other hand, in case that said packaging combination shall be used as a disposable packaging combination, a large amount of material, in particular the rigid tube is wasted, causing high costs.
Thus, it is an object of the present invention to provide an apparatus and a method with which a packaging combination can automatically and time and cost efficient may be assembled. Furthermore, it is an object of the present invention to provide a packaging combination producible on said assembling apparatus with which the above mentioned drawbacks have been overcome, and which allows an easy and save opening of the tubular casing.
According to the present invention, there is provided an apparatus for assembling a packaging combination which includes a tubular casing having a first end and a second end, wherein the tubular casing is partially filled with filling material and closed at its first as well as its second end by a closure means, like a closure clip, and wherein the partially filled tubular casing comprises a plait-like portion at its first end being at least approximately free of filling material. The packaging assembly further includes a dispensing device having a passageway extending through the dispensing device with an inlet opening at its one end and a dispensing opening at its other end for guiding and dispensing the filling material in a dispensing direction. The inventive apparatus comprises at least one supporting means for accommodating and retaining the at least partially filled tubular casing, including at least one cartridge for arranging the at least partially filled tubular casing in the assembling apparatus. The apparatus further includes at least one shaping means for creating a defined shape to the first end of the tubular casing, including at least one gripper means for gripping the first end of the at least
partially filled tubular casing and at least one forming shoulder for forming a defined shape to the said first end and at least one mounting means for mounting the dispensing device to said first end of the tubular casing.
The at least partially filled tubular casing is preferably vertically arranged in the assembling apparatus by means of said cartridge. Naturally, in order to form a defined shape to the first end and to mount a dispensing device thereto, the at least partially filled tubular casing may also be provided in a horizontal alignment or in any other suitable angle.
With the inventive apparatus, a packaging combination including a tubular casing and a dispensing device may automatically be assembled without the need of manpower and manual work, whereby a large amount of time and costs may be saved.
In a preferred embodiment of the inventive assembling apparatus, the cartridge is coupled with a drive means for moving said cartridge, whereby the tubular casing may be accurately be positioned to be processed.
The drive means for the cartridge may be of any suitable kind, like an electrical or pneumatically drive. In advantageous configuration, the drive means include a piston/cylinder assembly.
In a further advantageous embodiment, the forming shoulder of the shaping means is a shaping ring having an inner surface corresponding to the shape to be created of the first end of the tubular casing. Said shaping ring facilitates an easy and reliable forming of a defined shape to said first end of the tubular casing. Thereby, said shaping ring may be provided as a single part, but also may be composed of a number of segments.
To ensure a save and reliable gripping of the first end of the tubular casing, the gripper means of the shaping means include at least one claw for gripping said first end of the tubular casing. By using said gripper claws, a gripping force may be adjusted, dependent on the kind of the packaging material, for avoiding damages of sad casing material or the closing means. In another embodiment, the gripper means can be formed by a suction device which sucks in the first and of the tubular casing. Moreover, any other device for providing a “gripping force” to “grip” and hold the first end of the tubular casing can be used.
For creating a defined shape to the first end of the tubular casing, advantageously, the shaping means and/or the gripper means include a drive means for reversible moving the shaping means and the gripper means relative to each other.
The assembling apparatus according to the present invention can comprise receiving means for receiving the partially filled tubular casing. By means of said receiving means which may be a conventionally conveyor, the apparatus may be coupled to a clipping machine in which said tubular casing can be produced. In this case, it is possible to control the assembling apparatus on the basis of a signal from said clipping machine.
For automatically and defined providing the dispensing device to be mounted to the tubular casing, the apparatus comprises receiving means for receiving the dispensing device.
In order to prevent the filling material in the packaging combination from being contaminated or escaped, a closure cap may be attached to said packaging combination. Additionally or alternatively, for an easy and accurate dispensing of the filling material, also a dispensing nozzle may be provided. Accordingly, in an advantageous configuration, the assembling apparatus comprises attachment means for attaching a closure cap and or a dispensing nozzle to the dispensing device.
In a preferred embodiment of the inventive apparatus, at least the supporting means, the shaping means and the mounting means are arranged in work stations to enable an efficient assembling of the tubular casing and the dispending device.
Moreover, there is provided a method for assembling a packaging combination including a tubular casing having a first end and a second end, wherein the tubular casing is partially filled with filling material and closed at its first as well as its second end by a closure means, like a closure clip, and wherein the partially filled tubular casing comprises a plait-like portion at its first end being at least approximately free of filling material. The packaging combination further includes a dispensing device having a passageway extending through the dispensing device with an inlet opening at its one end and a dispensing opening at its other end for guiding and dispensing the filling material in a dispensing direction. The method comprises the steps of accommodating and retaining the at least partially filled tubular casing, positioning a forming shoulder at the first end of the tubular casing, gripping the first end of the tubular casing, forming a defined shape to the first end of said tubular casing by moving the tubular casing and the forming shoulder relative to each other, and mounting a dispensing device to said first end of said tubular casing.
According to the present invention, the method further comprises, not necessarily in this order, the steps of receiving the at least partially filled tubular casing, moving the at least partially filled tubular casing between working stations including at least the supporting means, the shaping means and the mounting means, and attaching a closure cap and a dispensing nozzle to the dispensing device.
The inventive method thereby provides the same advantages as disclosed in conjunction with the inventive assembling apparatus. With the inventive assembly apparatus as well as method, it is possible to assemble packaging combination with a dispensing device the axial length of which is substantially shorter than the axial length of the tubular casing. Thus, if such a packaging combination shall be used as a disposable packaging combination, the burden of the environment due to a bulky dispensing device, like in the prior art, is reduced.
Moreover, in accordance with the present invention, there is provided a packaging combination for accommodating and dispensing a viscous or granular filling material, the packaging combination comprises a tubular casing having a first end and a second end, wherein the tubular casing is partially filled with filling material and closed at its second end by a closure means, like a closure clip, wherein the first end is at least approximately free of filling material. The packaging combination further comprises a dispensing device having a passageway extending through the dispensing device with an inlet opening at its one end and a dispensing opening at its other end for guiding and dispensing the filling material in a dispensing direction. The dispensing device is attached to the first end of the partially filled tubular casing, wherein the first end extends inside the passageway of the dispensing device. At least a sealing element is removably attached to the dispensing device for closing and sealing the dispensing opening of the dispensing device.
This configuration of a packaging combination enables a safe and easy opening of the tubular casing by removing the sealing element from the dispensing opening and dispensing the filling material just by squeezing the filled tubular casing portion. Thus, an accidental discharge of filling material, while introducing the casing into a dispensing tube is prevented. Furthermore, the sealing device removably attached to the dispensing device, allows an indication of the original closure of the packaging combination and an easy and clean opening of said packaging combination without the need of any opening tools.
In an advantageous embodiment of the packaging combination according to the present invention, the dispensing device includes at least a first and a second portion, wherein the first portion extends from the inlet opening of the passageway in the dispensing direction and the second portion extends from the dispensing opening opposite to the dispensing direction, and wherein the inner circumferential dimensions of the first portion corresponds at least approximately to the outer circumferential dimensions of the tubular casing.
That means that the cross-section of the first portion of the dispensing device corresponds to the cross-section of the tubular casing, i.e. both, the first portion and the tubular casing, are of a circular cross-section, whereby the outer diameter of the tubular casing corresponds to the inner diameter of the first portion of the dispensing device. This allows a form-fit attachment of the dispensing device to the filled tubular casing. The term “circumferential dimension” has not only to be understood as the sole circumference, but also as a dimension characterizing a cross-section, like the length or width of a rectangle, a side length of a triangle or a diameter of a circle. Naturally, the first portion of the dispensing device and the tubular casing may be of any other suitable form, i.e. of a rectangular or triangular shape, the remarkable point is that their cross sections or circumferential dimensions correspond to each other.
According to the present invention, the packing combination includes a closure cap reversibly attachable to the dispensing device for releasing and closing the dispensing opening. A reversibly attachable closure cap reliably prevents the filling material from unintentionally escaping from the packaging combination and further allows storing and reusing an opened packaging.
In a preferred constitution, an indicating unit for indicating the originality of the closure of the dispensing opening provided at the dispensing device. Alternatively, the indicating unit may be attached to the closure cap. Said indicating unit surely displays whether or not the inventive packaging combination has already been opened.
As mentioned above, the dispensing device is attached to the tubular casing for forming the inventive packaging combination. To avoid the dispensing device from dropping off from the tubular casing, the dispensing device is secured to the first end of the tubular casing by an adhesive, in particular, by a hot-melt adhesive. Naturally, in case that sensitive filling materials are filled into the tubular casing, other adhesive means, like an adhesive tape, may be used, which e.g. may not be heated.
The object of the present invention may also be solved by a dispensing device for being attached to a tubular casing to form a packaging combination according to the invention described above.
In case that the dispensing device is provided as a disposable the amount material which has to be thrown away is remarkably reduced compared to the material in the case of known packaging combinations as described previously. This will reduce costs for producing the packaging combination and will also protect the environment.
Moreover, the object of the present invention may further be reached by a tubular casing partially filled with a filling material and closed at its first as well as its second end by a closure means, like a closure clip, for being combined with a dispensing device to from a packing combination according to the invention de-scribed above.
Further advantages and a preferred embodiment will be described in the following together with the drawings listed below. The expressions “left”, “right”, “below” and “above” are referred to the drawings in an alignment such that the reference numbers used can be read in normal.

In shaping station according to
Below cartridge 20, a drive assembly Z including two identical drive elements in the form of a piston/cylinder combination is arranged to act on piston 26 in order to move barrel 22 together with tubular casing 610 upwardly, whereby the upper or first end 612 of tubular casing 610, including plait-like portion P, which is closed by closure clip C, is positioned in the working area of shaping means 210. Tubular casing 610 is positioned in barrel 22 with its lower or second end 614, which is also closed by a further closure clip C, directed downwardly. Between the bottom of barrel 22 and the second end 614 of tubular casing 610, a fitting element F is positioned, for adapting cartridge 20 to the length of tubular casing 610 which has to project from the upper edge of barrel 22 about a predetermined length. For handling e.g. a longer tubular casing than that shown in
In the embodiment of packaging combination 600 according to
For fixedly attaching dispensing device 620 to tubular casing 610, an adhesive G, preferably a hot-melt adhesive or a glue, is disposed at the inside of the flange formed by annular offset 625 and first portion 622. The amount of adhesive G is sufficient for at least approximately filling the gap between first end 612 of tubular casing 610, annular offset 625 and first portion 622 of dispensing device 620.
As it further can be seen in
It has to be understood that, for attaching dispensing device 620 to first end 612 of tubular casing 610, the inner diameter of the second portion 626 of dispensing device 620, forming the dispensing opening 628, has to be at least slightly larger than the outer diameter of the closed closure clip C attached to first end 612. Accordingly, plait-like portion P closed by a closure clip C, has a length sufficient to extend through dispensing device 620 via inlet opening 624 and dispensing opening 628 to enable closure clip C closing first end 612, project from dispensing opening 628 in the dispensing direction D in order to remove closure clip C from first end 612 and for subsequently attaching sealing device 630 to dispensing opening 628.
A second embodiment of packaging combination 600 is shown in
Additionally, the packaging combination 600 includes a closure cap 40 for closing dispensing opening 28 of dispensing device 20 and a dispensing nozzle 50 for being attached to the dispensing opening 28, in order to dispense a desired amount of filling material.
Closure cap 640 includes a cylindrical portion 642 having a first end 642a and a second end 642b and a conical portion 644 being attached to second end 642b of cylindrical portion 642. As it can be seen in
In order to reversibly attach and release closure cap 640 to or from dispensing device 620, in particular to or from second portion 626 of dispensing device 620, an inner screw thread is provided at the inner surface of cylindrical portion 642 of closure cap 640, which matches with an outer screw thread provided at the outer surface of second portion 626 of dispensing device 620.
Closure cap 640 according to
As it further can be seen in
As mentioned above, packaging combination 1 of
The packaging combination 600 according to the present invention further comprises an indicating unit (not shown) for indicating the originality of the closure of the dispensing opening. Said indicating unit may have the form of a small sheet attached to the dispensing device 620, e.g. at the outside of annular offset 625 for being coupled with closure cap 640 when being closed for the first time. When opening originally closed packaging combination 600, the indicating unit is re-moved from closure cap 640 and/or from annular offset 625 of dispensing device 620, indicating that packaging combination 600 is not originally closed anymore, and further indicating, in case of the presence of a cutting element inside closure cap 640, that tubular casing 610 is opened and that filling material may escape from packaging combination 600 when releasing closure cap 640. The indicating unit may also be originally attached to the closure cap 640 and may then be coupled to dispensing device 620 when being closed for the first time. Naturally, an indicating unit may also be attached to any other suitable part of the packaging combination, where it's possible to indicate the originality of the closure of the dispensing device or at least of the dispensing opening. Naturally, also sealing device 630 provides an indicating unit for indicating the originality of the closure of the dispensing opening when present at dispensing opening 628.
Adhesive G provided at the inside of the flange formed by annular offset 625 and first portion 622 in order to secure dispensing device 620 to the first end 612 of tubular casing 610 has been described as being a hot-melt adhesive. Dependent on the material of tubular casing, which may be a suitable plastic foil or a natural material, the material of dispensing device 620, which is preferably made of plastic but also from any other suitable material, like a metal, the adhesive G may also be an other than a hot-melt adhesive. E.g. in case of temperature sensitive filling materials or casing material, a cold acting adhesive is required.
For assembling a packaging combination 600 including a tubular casing 610 and a dispensing device 620, a tubular casing 610 is received by horizontally aligned band conveyor 110 of receiving station 100. In receiving station 100, tubular casing 30 arranged horizontally on band conveyer 110 is transferred in a vertical position above cartridge 20 and placed in cartridge 20 with its first end 612 including plait-like portion P directed upwardly.
After positioning tubular casing 610 in cartridge 20, circular table 10 is rotated counter-clockwise about a predefined angle. Thereby, tubular casing 610 together with cartridge 20 is positioned in shaping station 200 below shaping means 210. In this position, shaping means 210, in particular claws 230 are in an opened position. Drive assembly D is actuated and moves cartridge 20 and tubular casing 30 upwardly in a position, in which first end 612 of tubular casing 610 is in the working area of shaping means 210. Thereafter, claws 230 will be closed for gripping first end 612 of tubular casing 610, in particular, closure clip C. Shaping ring 220 consisting of segments 220a, 220b, is positioned around and closely surrounds plat-like portion P. Shaping ring 220 is then moved down along plait-like portion P and away from claws 230, thereby creating a shape to the first end 612 of tubular casing 610, corresponding to the inner shape of shaping ring 220. Thereafter, shaping ring 220 is moved back towards claws 230 and away from plait-like portion P. Claws 230 are opened for releasing first end 612 of tubular casing 610, and cartridge 20 together with tubular casing 610 is shifted downwardly by drive assembly D.
Next, table 10 is rotated counter-clockwise for positioning cartridge 20 with tubular casing 610 having a defined shaped first end 612 in mounting station 300 below mounting means 310. In mounting station 300, a dispensing device 620 is provided by delivering device 320. Below delivering device 320, vertically movable gripper 330 is provided. In its upper position, gripper 330 grasps dispensing device 620 held by delivering device 320, and moves vertically downwardly to-wards first end 612 of tubular casing 610 provided by cartridge 20. Gripper 330 mounts dispensing device 620 to the first end 612 of tubular casing 610 by means of an adhesive G disposed at an inner surface of dispensing device 620 which comes into contact with the outer surface of tubular casing 610. Plait-like portion P thereby is guided through and extends beyond the dispensing opening 628 of dispensing device 620.
After moving gripper 330 in its opened position, table 10 further turns counter-clockwise for positioning cartridge 20 with tubular casing 610 and dispensing device 620 attached thereto, in the sealing station. In said sealing station, closure clip C at first end 612 of tubular casing 610 is gripped by gripping means, which may similarly constructed like gripper 330 and removed from plait-like portion P by respective removing means, like one or more cutting elements. Subsequently, a seal 630 is attached to dispensing opening 628 of dispensing device 620. Said sealing operation may be a heat sealing. Alternatively, sealing device 630 may also be mounted to dispensing device by a respective adhesive, like a hot-melt adhesive.
After the sealing operation, table 10 further turns counter-clockwise for positioning cartridge 20 with tubular casing 610 and dispensing device 620 in attachment station 400 vertically below the attachment means for attaching a closure cap 640 and/or a dispensing nozzle 650 to dispensing device 620. The attachment means include gripping and rotating means for gripping and screwing a closure cap 640 to dispensing device 620. Said attachment means are commonly known and thus, need not to be described in detail.
At discharge station 500, to which cartridge 20 together with the packing combination 600 is moved by further rotating table 10, packing combination 600 is re-moved from cartridge 20 by lifter arrangement 512 and deposited on conveyor arrangement 514 for being distributed from assembling apparatus 1.
In conjunction with
Shaping ring 220 according to
Moreover, attachment station 400 needs not necessarily be part of the assembling apparatus, in particular, in case that no closure cap has to be attached to the packaging combination.
As it can be seen in
Circular table 10 shown in
The present assembling apparatus includes receiving means in the form of a band conveyor as one possible embodiment of a conveyor device. For receiving a tubular casing being at least partially filled and comprising a plait-like portion, the assembling apparatus may be directly connected to a clipping machine by said conveying means. Otherwise, a respective storage device including a number of tubular casings, may be coupled to said conveying means.
