[0005] The invention relates to a carrier for storing natural casings, comprising: - a tube with a casing for receiving the natural casing along a longitudinal axis X of the tube; wherein the tube has a first end portion at a first end and a second end portion at a second end, - at least one first retaining means in the first end region of the tube to prevent the natural casing from slipping off the casing; and / or - at least one second retaining means at a second end region of the tube to prevent the natural casing from slipping off the casing; The carrier can be attached to a mandrel for pulling on the natural casing in the +X direction.

[0006] The second retaining means is a second flat retaining means, the cross section of which at a first position in the second end region along the tube has a first width B r1 and a second width B r2 with a width ratio B r1 / B r2 of at least 2 / 1, wherein the second flat-retaining means is flexible such that when the carrier is placed on the mandrel, the width ratio B r1 / B r2 can be expanded to less than 2 / 1.

[0007] The advantage is that the second flat retaining means is formed in one piece with the pipe and therefore cannot fall into the sausage meat in a sausage factory.

[0008] According to a first variant, the support comprises a tube and a second flat retaining means made of an elastic or a plastic material.

[0009] According to a further variant, the carrier comprises a tube, a second flat-retaining means, and a first flat-retaining means made of an elastic or plastic material. According to a particular variant, the carrier comprises a tube, a first flat-retaining means, the cross-section of which at a first position in the first end region along the tube has a first width B r1 and a second width B r2 with a width ratio B r1 / B r2 of at least 2 / 1. The first flattening means is flexible enough that when the carrier is placed on the mandrel, the width ratio B r1 / B r2 can be expanded to less than 2 / 1.

[0010] The advantage is that the second flat retaining means is formed in one piece with the pipe and therefore cannot fall into the sausage meat in a sausage factory.

[0011] According to an alternative variant, the carrier comprises a tube and a second bow-retaining means made of an elastic or plastic material. The second bow-retaining means is so flexible that it can be compressed simply by stripping off the natural casing already on the casing, allowing the natural casing to be expelled in the +X direction.

[0012] The advantage is that the carrier can be made from either an elastic plastic or a plastic plastic.

[0013] According to a particular variant, the support comprises a tube and a first arch retaining means made of an elastic material.

[0014] The advantage is that the elastic, first arched retaining means can be elastically curved inwards of the tube for the purpose of pulling a natural casing onto the carrier and can then spring elastically outwards again.

[0015] According to a variant, the support comprises a tube, a second sheet retaining means and a first sheet retaining means made of a plastic material.

[0016] The advantage is that the carrier can be made of both a plastic and a plastic material. The second plastic arched retaining means can be plastically curved or deformed inwardly of the tube for the purpose of removing a natural casing located on the carrier from the carrier, so that the natural casing (900) can be conveyed out in the +X direction.

[0017] According to a further variant of the carrier, the first inwardly curved, elastic bow retention element can be displaced within a groove of the mandrel up to a recess. The first inwardly curved bow retention element can be retracted over a first edge of the mandrel in the -X direction. The first bow retention element then snaps outward and prevents the natural casing already stretched onto the casing from slipping. However, if the carrier material is plastic, the first inwardly curved bow retention element will not snap out, so it must be spread outward using a spreading tool.

[0018] According to a particular variant, the carrier is of hybrid design and has a second retaining means formed integrally with the tube in the second end region and a detachable retaining means in the first end region. The second retaining means can be a flat retaining means or a curved retaining means. The first retaining means can be a rubber ring retaining means, a cap part, or an insert part.

[0019] The advantage is that the second retaining means, which is formed in one piece with the tube, cannot fall into the sausage meat in the sausage factory and the less critical, first retaining means can be designed as a loose retaining means according to the state of the art.

[0020] If the first retaining means is a rubber ring retaining means, an incision, e.g. as a slot, may be provided in the first end region of the pipe.

[0021] The advantage is that the rubber ring retaining device can partially engage in the incision and thus be secured there so that it cannot fall out.

[0022] According to a particular variant, the carrier comprises in the first end region at least one first elastic protruding retaining means which protrudes in the radial direction of the casing away from the longitudinal axis X of the tube and can be switched and fixed from a first protruding position to a second clamped position by means of a clamping device associated with a mandrel.

[0023] According to a preferred variant, a first retaining means, a second retaining means, and the tube are formed as a single piece. The advantage of the single-piece carrier is that no retaining means can fall into the sausage meat. Single-piece means that the retaining means are integrated into the tube.

[0024] Table 1 shows the diameter of the tube in relation to the caliber of the natural casing to be stored on it. Such a tube is typically 500 mm long and has a wall thickness of approximately 0.5 mm. For example, a 20 / 22 caliber natural casing is usually stored loosely and slipperily on a 15.2 mm diameter tube. This means that the natural casing exerts no force on the tube because the circumference of the 15.2 mm diameter tube is designed to fit the 20 / 22 natural casing for force-free assembly. Table 1: Outer diameter of tube vs. caliber of natural casing Kaliber Naturdarm Außendurchmesser Rohr Breite Rückhaltemittel [mm] Da [mm] Br [mm] mindestens 18 / 20 13,2 15 20 / 22 15,2 17 22 / 24 16,3 18 24 / 26 16,3 18 26 / 28 20,3 22 28 / 30 21,3 23

[0025] The retaining means according to the invention in the second end region of the tube is designed as an integrated component of the tube and has a width which is greater than the caliber of the natural casing to be accommodated, so that slipping out of the natural casing already accommodated on the tube is prevented.

[0026] The pipe and the retaining means may comprise elastic or plastic plastic or be made of an elastic or plastic plastic.

[0027] Elastic means flexible, supple, yielding, and springy. For example, an object made of an elastic material can return to the first position after being deformed from a first position to a second position, or spring back or snap back.

[0028] Elastic plastics have a deformation modulus of approximately 10 4 N / mm 2 .

[0029] An example of an elastic plastic is PE-HD, polyethylene (high density), with an elastic modulus of 1200 N / mm 2 .

[0030] Plastic means flexible, pliable, yielding, and exhibiting a permanent deformation after deformation. For example, an object made of a plastic material cannot return exactly to the original position after being deformed from a first position to a second position. It may happen that the return only partially occurs.

[0031] Plastics have a deformation modulus of < 10 -1 N / mm.

[0032] An example of a plastic is TPU-85, thermoplastic polyurethane elastomer, with a modulus of elasticity of 600 N / mm 2 .

[0033] According to a variant, the carrier comprises a tube and retaining means comprising a material made of fossil plastics or bio-based plastics, which may be, for example, PE, PU or PLA.

[0034] To design the carrier with a reduced carbon footprint, the tube and retaining means can comprise a degradable plastic that is home compostable and / or industrially compostable. Examples of such plastics include PLA and PBS. The carrier can be made of a bio-based plastic, such as PLA. Character list

[0036] Fig. 1 illustrates a schematic plan view of a carrier and shows a first embodiment of the invention. A carrier 100 for storing natural casing comprises a tube 120 with a casing 130 for receiving natural casing 900 along a longitudinal axis X of the tube 120. The tube 120 has a first end region 121 at a first end of the tube and a second end region 122 at a second end of the tube. The carrier 100 comprises at least one first retaining means in the first end region 121 of the tube 120 for preventing the natural casing 900 from slipping off the casing 130. The carrier 100 may additionally or as an alternative comprise a second retaining means at a second end region 122 of the tube 120 for preventing the natural casing 900 from slipping off the casing 130. According to the prior art, tubes are used for packaging natural casing. The tube is also called a hard tube.For the assembly of natural casing onto such a tube, a mandrel is used according to the prior art, onto which the tube is placed. The carrier 100 is placed onto a mandrel 300 according to the prior art in order to pull the natural casing 900 onto the casing of the carrier in the +X direction.

[0037] The object of the invention is to provide a carrier for storing natural casings in which the retaining means cannot fall into the sausage meat.

[0038] The solution to the problem according to the first embodiment of the invention is that the second retaining means is a second flat retaining means 480, the cross section of which at a first position 481 in the second end region 122 along the tube 120 has a first width B r1 and a second width B r2 with a width ratio B r1 / B r2of at least 2 / 1. The second flat retaining means 480 is flexible such that when the carrier 100 is placed on the mandrel 300, the second width B r2 can be expanded and the width ratio B r1 / B r2 is changed to less than 2 / 1.

[0039] Fig. 1a is a side view of the carrier of Fig. 1. In Fig. 1a shows three sub-regions of the tube 120: a first end region 121, a second end region 122, and a main region 123. The main region 123 is the unaltered tube 120 for storing the natural casing 900. This means that in all embodiments, the main region 123 remains unaltered. The retention means are implemented in the end regions.

[0040] This subdivision of the subareas applies to all embodiments of this invention. Fig. 1b shows a front view of the first flat retaining means 470 at position 471 in the first end region 121. Fig. 1c shows a cross-section of the tube 120 at position 472 in the first end region 121 and at position 482 in the second end region 122. Fig. 1d shows a cross section of the first end region 121 at position 471 and the second end region 122 at position 481. Fig. 1b and Fig. 1d show that a maximum height B r1 , which is also known as a maximum width B r1 of the first flat-retaining means 470, is substantially larger than a narrow width B r2 For a pipe with an outer diameter of 15.2 mm, the width B r1 = 24 mm, which is larger than the minimum width specified in Table 1 for this outer diameter, B r = 17 mm. To achieve this maximum width B r1 of the first flat retaining means 470, the pipe 120 is compressed at the first position 471 and thermoplastically fixed, so that the pipe at this point no longer Fig. 1c is round or has a width ratio B r1 / B r2 = 1, but a width ratio B r1 / B r2 >2 has.

[0041] The tube 120 can be polygonal, circular, or oval for all designs. If the width B for the tube 120 with an outer diameter of 15.2 mm is r1 = 24 mm is not sufficient, the tube 120 can be locally expanded in the first end region at the first position 471. The expansion can be carried out according to the state of the art using a suction technique and fixed thermoplastically. An expansion of 1 mm for the outer diameter 15.2 mm results in an increase in width B. r1 by B r1 = 24 mm on B r1= 25.4 mm. The second flat retaining means 480 can be implemented analogously. As an alternative, position 471 in the first end region 121 can replace position 473, so that position 473 is omitted. The advantage is that the main region 123 is enlarged, creating more space for receiving the natural casing 900 on the casing 130. An extension of the width B r1 is then possible but not advisable.

[0042] Analogously, position 481 in the second end region 122 can replace position 483, so that position 483 is omitted.

[0043] The support 100, comprising the tube 120 and the second flat-retaining means 480 and / or the first flat-retaining means 470, is formed as a single piece. That is, the flat-retaining means 470, 480 and the tube 120 are integrated into the support 100, so that no loose parts exist. The second flat-retaining means 480 in the second end region 122 is constructed analogously to the first flat-retaining means 470.

[0044] In a manufacturing process, the carrier 100 is placed in the direction +X on a mandrel 300 (e.g. Fig. 5). First, the second flat retention means 480 and then the first flat retention means 470 are expanded under the influence of the mandrel 300. The natural casing 900 is pulled onto the tube 120 via the first end of the tube 120 in the end region 121. The tube 120 is then removed from the mandrel 300. With a carrier 100 made of an elastic plastic, the previously expanded flat retention means 470, 480 contract, so that the original widths B r1 They shrink back down, thus preventing the flattening means 470 and 480 from slipping off the carrier 100. With a carrier 100 made of a plastic material, the previously expanded flattening means 470, 480 do not contract. In this case, the expanded flattening means 470, 480 must be flattened again. This can be done manually or using a flattening tool.

[0045] Fig. Figure 2 is a schematic plan view of a carrier according to a second embodiment of the invention. The second retaining means is a second sheet retaining means 180, which is curved outwardly with respect to the longitudinal axis X ( Fig. 3 Magnification M', Fig. 3a).

[0046] The second bow-retaining means 180 is flexible and can be deformed by applying force to a surface of the second bow-retaining means 180 in the direction toward the longitudinal axis X of the tube 120. The force is applied outside the tube 120 to a surface of the second bow-retaining means 180 facing away from the longitudinal axis X of the tube 120, so that the second outwardly bulging bow-retaining means 180 deforms inward of the tube 120 toward the longitudinal axis X of the tube 120. Thus, the obstructing function of the second bow-retaining means 180 is eliminated, so that a natural casing 900 already located on the casing 130 can be conveyed out in the +X direction.

[0047] Fig. 2a shows an enlargement M of the second sheet retaining means 180 of Fig. 2. The second sheet retaining means 180 is partially separated from the tube 120 by two slots, the first slot 181 of the second retaining means 180 and the second slot 182 of the second retaining means 180.

[0048] Fig. 2b shows an enlargement N of the first sheet retaining means 170 of Fig. 2. The first sheet retaining means 170 is partially separated from the tube 120 by two slots, the first slot 111 of the first retaining means 170 and the second slot 172 of the first retaining means 170.

[0049] Fig. Figure 3 is a schematic side view of the carrier 100 of Fig. 2. In Fig. 3, the first sheet retaining means 170 and the second sheet retaining means 180 are curved outwards.

[0050] Fig. 3a shows an enlargement M' of the second sheet retaining means 180 of Fig. 3. The second arc-shaped retaining means 180 is curved outward and has an arc shape. Therefore, the retaining means in the second end region 122 of the tube 120 is called an arc-shaped retaining means. That is, "arc-shaped retaining means" refers to the arc-shaped design of the retaining means.

[0051] Fig. 3b shows an enlargement N' of the first sheet retaining means 170 of Fig. 3 analogous to the magnification M'.

[0052] Fig. Figure 4 is a schematic side view of the carrier 100 of Fig. 2. In Fig. 4, the first sheet retaining means 170 and the second sheet retaining means 180 are curved inwards. Fig. 4a shows an enlargement M'' of the second sheet retaining means 180 of Fig. 4. Fig. 4b shows an enlargement N'' of the first sheet retaining means 170 of Fig. 4.

[0053] As in Fig. 4 and Fig. As shown in Figure 4b, the first, flexible bow-retaining means 170 can be elastically deformed by applying force to a surface of the first bow-retaining means 170 in the direction toward the longitudinal axis X of the tube 120, such that the first bow-retaining means 170 can be curved or deformed inward of the tube 120. Thus, a natural casing 900 can be pulled onto the casing 130 along the +X direction via the first bow-retaining means 170. In a method for assembling the natural casing, the carrier 100 can be pulled in the +X direction onto a mandrel 300 according to the invention ( Fig. 5). The first inwardly curved sheet retaining means 170 is displaced within a groove 320 of the mandrel 300 up to a recess 330. This eliminates the obstructing function of the first sheet retaining means 170, so that the natural casing 900 can be pulled onto the casing 130 in the +X direction without any obstruction. The carrier 100 can then be removed from the mandrel 300. In doing so, the first inwardly curved sheet retaining means 170 is guided back over a first edge 370 of the mandrel 300 in the -X direction such that the first sheet retaining means 170 can snap outward if the carrier 100 comprises an elastic plastic. However, if the carrier 100 comprises a plastic plastic, the first sheet retaining means 170 does not spring outward. Thus, the first inwardly curved sheet retaining means 170 must be spread outwards by means of a spreading tool during or after removal from the mandrel 300.For the first sheet retaining means 170, it is important whether the first sheet retaining means 170 comprises an elastic plastic, because in this case, snapping back, springing back, or rebounding is possible and advantageous. If the first sheet retaining means 170 comprises a plastic plastic, the first inwardly curved sheet retaining means 170 must be spread outward.

[0054] The carrier 100 may additionally or alternatively comprise a second retaining means at a second end region 122 of the tube 120 to prevent the natural casing 900 from slipping off the casing 130. The second sheet retaining means 180 is flexible enough to be elastically or plastically compressed simply by stripping off the natural casing 900 already located on the casing 130, so that the natural casing 900 can be conveyed out in the +X direction. For the second sheet retaining means 180, it is irrelevant whether the second sheet retaining means 180 comprises an elastic or a plastic material.The second sheet retaining means 180 only needs to be flexible enough so that when the natural casing 900 is stripped over the second sheet retaining means 180, the second sheet retaining means 180 can be compressed by a force generated by an inherent tension in the inner circumference of the natural casing, and the natural casing 900 can be conveyed out in the +X direction. The second sheet retaining means 180 can also be manually pushed inward, if necessary, before the natural casing 900 is conveyed out in the +X direction.

[0055] It is advantageous if the number of bend retention devices in an end region 121, 122 of the tube 120 is kept low so that the homogeneity of the casing 130 is not disturbed in these regions. The casing 10 in the main region 123 is undisturbed. The casing 130 in the second end region 122 is disturbed by the presence of the second bend retention device 180. With a single second bend retention device 180, the casing 130 is barely disturbed. With 10 second bend retention devices 180, the casing 130 is severely disturbed. Maintaining an undisturbed casing in the second end region 122 has an advantage for the overlap of the natural casing pieces 900. The overlap of the natural casing pieces 900 is maintained better the less the casing 130 is disturbed.

[0056] In Fig. In Figure 6c, the undisturbed area is indicated by the arrows U. The disturbed area is where the second arch retention means 180 are located.

[0057] Fig. Figure 6 is a schematic plan view of a carrier and shows another embodiment of the invention. The retaining means in the second end region 122 is identical to the second sheet retaining means 180 of the previous embodiment as shown in Figures Fig. 2, Fig. 2a, Fig. 3, Fig. 3a, Fig. 4, Fig. 4a. Fig. 6a is an enlargement L of the second sheet retaining means 180 of Fig. 6. Fig. Figure 6c is a schematic front view of the second sheet retaining means 180 of Fig. 6.

[0058] Fig. 6b shows a magnification K of Fig. 6. The enlargement K shows that the carrier in the first end region 121 comprises a rubber ring retaining means 270 according to the prior art. Fig. Figure 6b shows that, in contrast to the prior art, the carrier in the first end region 121 comprises at least one notch 271 for partially receiving the rubber ring retaining means 270. Thus, the rubber ring retaining means 270 gets caught in the notch 271 and makes it difficult for the rubber ring retaining means 270 to fall out. Or makes it impossible for the rubber ring retaining means 270 to fall out. The notch 271 is also shown in Fig. 6 shown. Fig. 7 is a schematic side view of Fig. 6. Fig. 7a shows a magnification L' of Fig. 7. According to Fig. 7 and Fig. 7a, the second arch retaining means 180 is curved outwards.

[0059] Fig. 8 is a schematic side view of Fig. 6. Fig. 8a shows a magnification L'' of Fig. 8. According to Fig. 8 and Fig. 8a, the second arch retaining means 180 is deformed or curved inwards.

[0060] In some previous embodiments, when the outwardly bulging second sheet retaining means 180 is bulged inward with the application of force, it is then referred to as an inward deformation. Applying a force to an outer surface of the outwardly bulging second sheet retaining means 180 does not actually cause a clearly defined inward bulging of the second sheet retaining means 180, but rather a wave-shaped, irregular flattening of the second sheet retaining means 180, which is very advantageous because the width B r of the second sheet retaining means 180 is thus smaller than a minimum width B r from Table 1 and thus the obstruction function of the second sheet retaining means 180 is eliminated, so that the natural casing 900 already received on the casing 130 can be conveyed out in the direction +X without hindrance.

[0061] Fig. 9 shows a carrier 100 according to the embodiment of Fig. 6, Fig. 7 and Fig. 8 with a natural casing 900 on it.

[0062] Fig. Figure 10 is a schematic side view of a carrier and shows a further embodiment of the invention. The retaining means in the second end region 122 is identical to the second sheet retaining means 180 of the previous embodiments as shown in Figures Fig. 2, Fig. 2a, Fig. 3, Fig. 3a, Fig. 4, Fig. 4a, Fig. 6, Fig. 6a, Fig. 7, Fig. 7a, Fig. 8, Fig. 8a and Fig. 9 shown.
