[0007] The invention relates to a carrier for storing natural casings, comprising: - a tube with a casing for receiving natural casing along a longitudinal axis X of the tube; wherein the tube has a first end region at a first tube end and a second end region at a second tube end; - at least one second retaining means at the second end region of the tube for preventing the natural casing from slipping off the casing; wherein the second retaining means is a second strip retaining means and comprises: - at least a second strip extending along the longitudinal axis X in the direction +X as a continuation of the shell; - at least one second strip receptacle having an opening on the casing on the opposite side of the second strip;

[0008] The carrier can be attached to a mandrel for pulling the natural casing in the +X direction. At least one second gap extending between the second strip holder and the second tube end is assigned to the tube in the second end region.

[0009] The second strip can be bent and guided through the second gap to the second strip receptacle such that the second strip is captured in the second strip receptacle and partially projects out of the jacket away from the longitudinal axis X.

[0010] According to a first variant, the carrier comprises a second strip retaining means and a tube which are formed in one piece.

[0011] The advantage is that the second strip retaining device cannot fall into the sausage meat in a sausage factory.

[0012] According to a further variant, the carrier comprises, along the longitudinal axis X, a second tube end which is spaced from a second strip receptacle by more than one tube outer radius.

[0013] The advantage is that a second natural casing overhang in the second end area of ​​the natural casing already pulled onto the casing of the pipe cannot hang over the end of the pipe.

[0014] According to a particular variant, the carrier comprises a second strip having second strip incisions into which the second strip receptacle can penetrate.

[0015] The advantage is that the second strip is thus secured. This contributes to safer and better slip prevention.

[0016] According to an alternative variant, the carrier comprises a second gap in the second end region between the second strip receptacle and the second tube end for the strip to pass through. The gap is designed as a slot.

[0017] The advantage is that the slot prevents the strip from being accidentally retracted and contributes to the stability of the anti-slip barrier.

[0018] According to a variant, the carrier comprises in the second end region a second strip receptacle which is designed as a slot partially associated with the tube in the radial direction.

[0019] The advantage is that the second strip holder acts as a slot to hold the strip in place and thus contributes to the stability of the anti-slip barrier.

[0020] According to a further variant, the carrier comprises a second strip which is a strip length, which is the longest dimension of the strip and is referred to here as a predetermined width, wider than the caliber of the natural casing.

[0021] The advantage is that the larger width of the strip prevents the natural casing, which is already stretched over the casing of the tube, from slipping out.

[0022] According to a further variant, the carrier comprises a first retaining means in the first end region of the tube, which is a first strip retaining means. The first strip retaining means has the properties of the second strip retaining means and prevents the natural casing already wound onto the casing of the tube from slipping out.

[0023] The advantage is that the first strip restraint acts as a stable slip barrier.

[0024] According to a preferred variant, a first retaining means, a second retaining means and the tube are formed in one piece.

[0025] The advantage of the one-piece carrier is that no retaining element can fall into the sausage meat. One-piece means that the retaining elements are integrated into the tube.

[0026] According to a particular variant, the support comprises a tube, a second strip retention means and a first retention means, which is any retention means from the prior art or from the applicant's previous applications.

[0027] 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 Caliber natural casing Outer diameter of pipe Wide restraint devices [mm] There [mm] Br [mm] at least 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

[0028] 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.

[0029] The pipe and the retaining means may comprise elastic or plastic plastic or be made of an elastic or plastic plastic.

[0030] 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.

[0031] Elastic plastics have a deformation modulus of approximately 10 4 N / mm 2 .

[0032] An example of an elastic plastic is PE-HD, polyethylene (high density), with an elastic modulus of 1200 N / mm 2 .

[0033] 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.

[0034] Plastics have a deformation modulus of < 10 -1 N / mm.

[0035] An example of a plastic is TPU-85, thermoplastic polyurethane elastomer, with a modulus of elasticity of 600 N / mm 2 .

[0036] 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.

[0037] 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

[0039] Fig.1 illustrates a schematic plan view of a carrier 100 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 state of the art, tubes are used for packaging natural casings. These tubes are also called hard tubes.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 100 in the +X direction.

[0040] 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.

[0041] The solution to the problem according to the first embodiment of the invention is that the second retaining means of the carrier 100 is a second strip retaining means 152.

[0042] Fig.Figure 1 is a plan view of the carrier 100 and illustrates three partial 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.

[0043] This subdivision of the subareas applies to all embodiments of this invention. Fig. 1 shows the second strip retention means 152 in the second end region 122, which has a first strip 153 connected to the casing 130 at a second connection point 151. A longitudinal axis X with a directional arrow indicates the direction of the natural casing 900 being pulled on at the first end region 121 and the natural casing 900 being pulled off at the second end region 122 of the tube 120. Fig. 2 is a side view of Fig.1 and shows the second strip retaining means 152 in a first position of the second strip 153 extending along the longitudinal axis X in the direction +X. Fig. 3 is a side view of Fig. 1 and shows that the second strip 153 has bent around the second connection point 151 by approximately 90°.

[0044] Fig. 4 shows a front view of the tube 120. Here it can be seen that the second strip 153 is bent by approximately 90°.

[0045] In one method, the second strip 153 is wound around the second connection point 151 (see Fig.1) is bent by approximately 90° and guided through a second gap 154 ​​until it reaches a second strip receptacle 155. The second strip receptacle 155 is an opening on the casing 130, on the opposite side of the second strip 153. The second gap 154 ​​extends from the second strip receptacle 155 to a second tube end 156 in the second end region 122. Fig. Figure 5a shows how the second strip 153 is surrounded by the second strip receptacle 155.

[0046] Fig. Figure 7 shows a schematic plan view of a second strip 153 of the carrier 100. The second strip 153 may comprise at least one second strip cut 157 into which, as shown in Fig. 6, the second strip holder 155 penetrates and thus fixes the second strip 153 better.

[0047] All descriptions for the second strip retaining means 152 as in Fig.1a, also applies in a similar manner to the first strip retaining means 142.

[0048] Fig. 1b shows a side view of Fig. 1a shows the first end region 121 at the first end of the tube 120 and shows that the first strip retaining means 142 is in a first position of the first strip 143 extending along the longitudinal axis X in the direction -X. Fig. 1c is a side view of Fig. 1a and shows that the first strip 143 is arranged around the first connection point 141 (see Fig. 1a) has been bent by approximately 90°.

[0049] Fig. Figure 5b shows how the first stripe 143 is surrounded by the first stripe image 145.

[0050] Fig. Fig. 7a shows a schematic plan view of a first strip 143 of the carrier 100. The first strip 143 may comprise at least one first strip cut 147 into which, as in Fig.6b, the first strip holder 145 penetrates and thus fixes the first strip 143 better.

[0051] Fig. Figure 8 is an elevational view of the second end portion 122 of the carrier 100 of Fig. 5,

[0052] Fig. 8a is a detailed view of the bottom view of the first end region 121 of the carrier 100 of Fig. 1a.

[0053] Fig.9 shows a schematic side view of the carrier 100 with a natural casing 900 already mounted thereon. The first strip 143 is in the second position and acts as a slip barrier, ensuring that the natural casing 900 does not slip out on the opposite side either. However, the natural casing 900 can move at this point by a limited length 901 in the direction -X and be held stable there. Therefore, it is important that a first distance 148 is provided as a reserve between the first strip holder 145 and the first tube end 146 so that the natural casing 900 cannot slip beyond the first tube end 146. The first distance 148 can be in the order of magnitude of the tube outer radius R a The first distance can preferably be between 0.25 × R a and 2 × R a or more preferably 1 × R a be.

[0054] The second strip retention means 152 can be square or rounded at the distal end, i.e., away from the second connection point 151 of the second strip 153. The rounded second strip 153 is gentler on the natural casing 900 and avoids damage to the natural casing 900.

[0055] A slit-like first strip receptacle 145 and a first slit-like gap 144 were indirectly described above. These slits contribute to the robustness of the first strip retaining means 142. A first reinforcing means 149 can further contribute to the robustness of the first strip retaining means 142. The first reinforcing means 149 can, for example, be at least one fold or at least one groove, which increases the flexural rigidity of the first strip retaining means 142.

[0056] Everything that applies to the first strip restraint 142 also applies to the second strip restraint 152. Only the orientation directions are different, namely the -X direction and the +X direction.

[0057] For the purpose of assembly, the carrier 100 is placed on a mandrel 300 (not shown), which is assigned a clamping device according to the prior art. The first strip retaining means 142 (see Fig. 1a, Fig. 1b) is manually fixed or held in place by means of the clamping device of the mandrel 300. Thus, the first strip retaining means 142 does not stand loose in the way, so that the natural casing 900 can be pulled onto the casing 130 in the direction +X without any obstacle (see Fig. 9). The carrier 100 can then be removed from the mandrel 300 in the direction -X. Now the first strip retaining means 142 is moved from the first position to the second position (see Fig. 1b, Fig.1c), so that the first strip retaining means 142 prevents the natural casing 900 already pulled onto the casing 130 from slipping out. The second strip retaining means 152 (see Fig. 1b, Fig. 2) is taken from the first position (see Fig. 2) into the second position (see Fig. 3) so that the second strip retaining means 152 prevents the natural casing 900 already pulled onto the casing 130 from slipping out (see Fig. 9).

[0058] Fig.8a shows that the casing 130 has a substantially undisturbed surface in the first end region 121. Undisturbed means that the casing 130 is not interrupted by the presence of a first strip retaining means 142 or a first gap 144. Maintaining an undisturbed casing 130 in the first end region 121 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.

[0059] Fig.8 shows that the casing 130 has a substantially undisturbed surface in the second end region 122. Undisturbed means that the casing 130 is not interrupted by the presence of a second strip retaining means 152 or a second gap 154. 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.

[0060] A combination of retention devices is possible and useful. For example, according to Table 2, the following retention devices can be provided in the first end region 121 and the second end region 122 of the pipe 120: Table 2: Combination of slip obstacles Second end area 122 First end area 121 second strip restraint device 152 a bow retention device second strip restraint device 152 a flat-retaining device second strip restraint device 152 a rubber ring restraint device second strip restraint device 152 a stand-off restraint device second strip restraint device 152 a plug-in part second strip restraint device 152 a hat

[0061] The material for the inventive tube 120 can at least partially comprise a flexible, environmentally friendly, degradable, and food-grade plastic. "Degradable" means home compostable and / or industrially compostable. Such degradable plastics include polybutylene succinate and polylactic acid, which are bio-based plastics and can be produced from renewable raw materials. Polyethylene can also be produced from renewable raw materials.

[0062] Examples of fossil-based plastics include polyamide and polyolefin. Another fossil-based plastic is polyethylene. Polyurethane is also used in this context and is a fossil-based plastic. QUOTES CONTAINED IN THE DESCRIPTION
