    • DETAILED DESCRIPTION OF THE INVENTION
  • The invention is explained in the following with the aid of the drawings in which like reference numbers represent like elements.
  • FIG. 1 shows a front view of a tube 10 in accordance with a first embodiment of the invention. Tube 10 has a main body 100 that is deformable such that deformation of main body 100 causes a material stored inside tube 10 to be expelled from an opening 210 located at a first end 200 of main body 100. A seal 300 is located at an end of main body 100 opposite opening 210. During manufacturing of tube 10, seal 300 is formed to prevent the material stored in tube 10 from exiting tube 10 from the end of main body 100 at which seal 300 is formed. A contour 310 is formed as part of, or near, seal 300. Contour 310 provides surfaces that facilitate gripping of tube 10 by a wrapping device used to squeeze the material stored in tube 10 out of opening 210. FIG. 2 shows a side view of the embodiment of the invention shown in FIG. 1.
  • FIG. 3 shows an enlarged view of the seal and contour area of the tube shown in FIG. 2. Contour 310 in this embodiment has a trough 312 that forms bearing surfaces 314. Bearing surfaces 314 are provided to interact with a wrapping tool used to wrap main body 100 around seal 300. Although four bearing surfaces 314 are shown in FIG. 3, less than all four can be used to engage the wrapping tool.
  • FIG. 4 shows a partial front view of tube 10 having a non-continuous contour 320. From this example, contour 320 is comprised of four holes 322.
  • Each hole 322 has, in this example, two bearing surfaces 324. The example shown in FIG. 4 can be considered a non-continuous version of the contour shown in FIGS. 1-3. Because seal 100 exists in the horizontal spaces between holes 322, holes 322 can be used instead of a plurality of small troughs.
  • FIGS. 5 and 6 show the interaction of wrapping tools with the embodiments of the invention shown in FIGS. 1-4. FIG. 5 shows a wrapping tool 20 having an upper prong 22, a lower prong 24 and a handle 26. As shown in FIG. 5, wrapping tool 20 is slid onto contour 310 of tube 10 so that upper prong 22 interacts with upper bearing surface 314 and lower prong 24 interacts with lower bearing surface 314′. Once wrapping tool 20 is fully engaged with contour 310, handle 26 can be rotated in the direction of the arrow shown in FIG. 5 to twist contour 310 relative to main body 100 such that main body 100 is wrapped around contour 310. Although this example has been described such that upper prong 22 interacts with upper bearing surface 314 and lower prong 24 interacts with lower bearing surface 314′, it is noted that only one of the prongs need interact with only one of the bearing surfaces during the wrapping procedure. Further, it is possible that a lower surface of lower prong 24 can interact with bearing surface 314″. FIG. 6 shows a wrapping tool 30 having an upper prong 32, a lower prong 34 and a handle 36. Wrapping tool 30 interacts with the example of seal 300 shown in FIG. 4. Upper prong 32 of wrapping tool 30 has a number of protrusions 33 that interact with holes 322 and one or more of bearing surfaces 324. Wrapping tool 30 is moved into position such that protrusions 33 are inserted into holes 322 and then handle 36 is rotated in the direction of the arrow in FIG. 6 in order to twist contour 320 such that main body 100 is wrapped around contour 320.
  • Although particular configurations of wrapping tools 20, 30 are shown in FIGS. 5 and 6, it is noted that wrapping tools of different configurations can be used to interact with the bearing surfaces shown, or other bearing surfaces, of the contours shown and described in this application.
  • FIGS. 7-9 show an embodiment of the invention in which the contour is a thickened portion 330 having a bearing surface 334. FIG. 7 is a partial side view of this embodiment showing bearing surface 334 located on a lower surface of thickened portion 330. FIG. 8 is a partial front view shown in an example of this embodiment in which thickened portion 330 is continuous along the entire width of seal 300. FIG. 9 shows a partial front view of an alternate example of the embodiment shown in FIG. 7 in which the thickened portion comprises a plurality of thickened portions 330′, some or all of which having a bearing surface 334′. As such, FIG. 9 is a non-continuous example of the thickened portion 330 shown in FIG. 8.
  • FIGS. 10-12 show an embodiment of the invention in which two thickened portions 340 are provided. FIG. 11 is a partial front view of the embodiment shown in FIG. 10 in which both thickened portions 340 are continuous along the entire width of seal 300. Thickened portions 320 have bearing surfaces 344 located on their undersides. FIG. 12 is a partial front view of an alternate example of the embodiment shown in FIGS. 10 and 11. In FIG. 12, the contour comprises four thickened portions 340′ on each side of seal 300, one or more of thickened portions 340′ having a bearing surface 344′.
  • FIGS. 13-16 show an embodiment of the invention having a cross shaped contour. The contour in this embodiment comprises two protrusions 350 that protrude from seal 300 a distance greater than the thickness of protrusions 350. Each protrusion 350 is shown as having a bearing surface 354 on its underside. It is noted that the upper surfaces of one or both of protrusions 350 can be serve as a bearing surface instead of, or in addition to, one or both bearing surfaces 354. FIG. 14 shows a partial front view of the embodiments shown in FIG. 13 in which protrusions 350 are continuous along the entire width of seal 300. FIG. 15 shows an alternate example of the embodiments shown in FIG. 14 in which the contour comprises four protrusions 350′. One or more of the upper and/or lower surfaces of protrusions 350′ can act as bearing surface 354′. FIG. 16 shows a second alternate example of the embodiment shown in FIG. 14. In this example, protrusions 350″, in conjunction with seal 300, form a T-shape as opposed to the cross shape formed by the protrusions shown in FIGS. 14 and 15. Lower surfaces of protrusions 350″ are shown as bearing surfaces 354″ in FIG. 16. However, it is noted that the upper surfaces of protrusions 350″ can act as bearing surfaces along with, or instead of, the lower surfaces of protrusions 350″.
  • While particular examples of contours in accordance with the invention have been shown in the figures, it is noted that many other configurations are possible within the scope of the invention. Further, a plurality of different wrapping tool configurations are usable with each contour configuration.
  • The invention has been described in detail with respect to preferred embodiments and it will now be apparent from the foregoing to those skilled in the art that changes and modifications may be made without departing from the invention in its broader aspects. The invention, therefore, is intended to cover all such changes and modifications that fall within the true spirit of the invention.
