DETAILED DESCRIPTION OF THE INVENTION The invention is explained below with the help of the drawings, in which like reference numerals represent similar elements. Figure 1 shows a front view of a tube 10 according to a first embodiment of the invention. The tube 10 has a main body 100 which is deformable, such that the deformation of the main body 100 causes the material stored inside the tube 10 to be expelled through an opening 210 located in a first end 200 of the main body 100. A seal 300 is located at one end of the main body 100 opposite the opening 210. During the manufacture of the tube 10, the seal 300 is formed to prevent material stored in the tube 10 from exiting the tube 10 from one end of the body. 100 where the seal 300 is formed. A contour 310 is formed as part of or near the seal 300. The contour 310 provides surfaces that facilitate the grip of the tube 10 by the wrapping device used to squeeze the material stored in the tube. 10 outside the opening 210. Figure 2 shows a side view of the embodiment of the invention shown in Figure 1. Figure 3 shows an enlarged view of the area of the seal and the outline of the tube shown in Figure 2. The contour 310 in this embodiment has a trough 312 which forms the support surfaces 314. The support surfaces 314 are provided to interact with a wrapping tool used to wrap the main body 100 around the seal 300. Although four support surfaces 314 are shown in Figure 3, less than four can be used to couple the tool. envelope. Figure 4 shows a partial front view of the tube 10 having a contour 320 not continuous. From this example, the contour 320 is composed of four holes 322. Each orifice 322 has, in this example, two bearing surfaces 324. The example shown in Figure 4 can be considered a non-continuous version of the contour shown in Figures 1 to 3. Because there is a seal 100 in the horizontal spaces between the holes 322, the holes 322 can be used instead of a plurality of small troughs. Figures 5 and 6 show the interaction of the wrapping tools with the embodiments of the invention shown in Figures 1 to 4. Figure 5 shows a tool 20 having a upper tine 22, a lower tine 24 and a handle 26 As shown in Figure 5, the wrapping tool 20 slides over the contour 310 of the tube 10, so that the upper prong 22 interacts with the lower supporting surface 314 and the lower prong 24. interact with the bottom supporting surface 314 '. Once the wrapping tool 20 is completely engaged with the contour 310, the handle 26 can be rotated in the direction of the arrow shown in Figure 5 to twist the contour 310 relative to the main body 100, so that the The main body 100 is wrapped around the contour 310. Although this example has been described with the upper pin 22 interacting with the lower support surface 314, and the lower pin 24 interacts with the lower support surface 314 ', it should be noted that only one of the tines needs to interact with only one of the support surfaces during the wrapping process. Furthermore, it is possible that the lower surface of the lower prong 24 may interact with the supporting surface 314. Figure 6 shows a wrapping tool 30 having an upper prong 32, a lower prong 34 and a handle 36. The tool 30 of wrapping interacts with the example of the seal 300 shown in Figure 4. The upper prong 32 of the wrapping tool 30 has several projections 33 interacting with the holes 322 and one or more of the bearing surfaces 324. The wrapper moves to a position, so that the projections 33 are inserted into the holes 322 and then the handle 36 rotates in the direction of the arrow in Figure 6, in order to twist the contour 320 so that the main body 100 is wrapped around contour 320. Although particular configurations of casing tools 20, 30 are shown in Figures 5 and 6, it should be noted that wrapping tools of different configurations can be used to interact with the shown support surfaces or other support surfaces of the contours shown and described in this application. Figures 7 to 9 show an embodiment of the invention wherein the contour is a thickened portion 330 having a bearing surface 334. Figure 7 is a partial side view of this embodiment, which shows the bearing surface 334 located on the bottom surface of the thickened portion 330. Figure 8 is a partial front view shown in an example of this embodiment, wherein the thickened portion 330 is continuous along the full width of the seal 300. Figure 9 shows a partial front view of an alternative example of the embodiment shown in Figure 7, wherein the thickened portion comprises a plurality of thickened portions 330 ', some of which have a bearing surface 334'. As such, Figure 9 is a non-continuous example of the thickened portion 330 shown in Figure 8. Figures 10 to 12 show one embodiment of the invention, wherein two thickened portions 340 are provided. Figure 11 is a partial front view of the embodiment shown in Figure 10, wherein the thickened portions 340 are continuous along the full width of the seal 300. The thickened portions 320 have support surfaces 344 located on their bottom sides. Figure 12 is a partial front view of an alternative example of the embodiment shown in Figures 10 and 11. In Figure 12, the The contour comprises four portions 340 'thickened on each side of the seal 300, one or more of the thickened portions 340' has a bearing surface 344 '. Figures 13 to 16 show an embodiment of the invention having a cross-shaped contour. The contour in this embodiment comprises two projections 350 projecting from the seal 300 at a distance greater than the thickness of the projections 350. Each projection 350 is shown with a support surface 354 on its underside. It should be noted that the upper surfaces of one or both of the projections 350 can function as a support surface, instead of, or in addition to, one or both support surfaces 354. Figure 14 shows a partial front view of the modalities shown in Figure 13, where the projections 350 are continuous along the full width of the seal 300. Figure 15 shows an alternative example of the modalities shown in Figure 14, wherein the contour comprises four projections 350 '. One or more of the lower and / or upper surfaces of the projections 350 'may act as the supporting surface 354'. Figure 16 shows a second alternative example of the embodiment shown in Figure 14. In this example, the projections 350", together with the seal 300, form a T-shape, opposite to the cross shape formed by the projections shown in FIG. Figure 14 and 15. The lower surfaces of the projections 350"are shown as support surfaces 354" in Figure 16. However, it should be noted that the surfaces The upper portions of the projections 350"may act as support surfaces together with or instead of the lower surfaces of the projections 350". While the particular examples of contours in accordance with the invention have been shown in the Figures, it should be noted that many other configurations are possible within the scope of the invention. In addition, a plurality of different wrapping tool configurations can be used for each contour configuration. The invention has been described in detail with respect to the embodiments and it will be apparent to those skilled in the art that changes and modifications can be made without departing from the invention in its broader aspects. Therefore, the invention is intended to encompass all changes and modifications that fall within the true spirit of the invention.
