Definitions

  • the present invention relates to a collapsible tubular container, such as a plastic squeeze tube, having a closure cap and a protective shoulder about the head of the tube.
  • Collapsible plastic tubes are used in the packaging and dispensing of a myriad of consumer products such as cosmetics, toothpaste, shampoo, foodstuffs and the like.
  • the collapsible plastic tubes are usually formed from a cylindrical tubular plastic body which has a head portion, on which a neck is provided having a dispensing orifice formed therethrough, the head secured to and closing off one end of the tubular body.
  • a closure cap is releasably secured to the neck to close off the dispensing orifice and the tube is filled with the desired consumer product and the opposite end of the tube sealed, such as by heat sealing.
  • the user removes the cap and squeezes the tubular plastic body to force tube contents through the dispensing orifice in the neck. After use, the cap is re-secured to the neck to protect the tube contents from the environment.
  • the appearance of the tubular container is important. Often, when the closure cap is secured to the head of a tubular body, a slight spacing or gap is present between the bottom edge of the closure cap and the head of the tube, which gap is magnified by any pressure on the wall of the tubular plastic body. The elimination or concealment of such a gap is desirable in order to provide a most aesthetically appealing consumer package.
  • a collapsible tubular container having a closure cap is provided where the bottom edge of the closure cap is hidden from view by a protective shoulder on the neck of the tubular container.
  • the tubular container preferably formed from a thermoplastic such as polyethylene, has a tubular body portion with a cylindrical wall and a head portion that is sealed to the tubular body portion at one end.
  • the head portion is usually in the shape of a truncated cone and has a neck extending upwardly therefrom, the neck having a dispensing orifice formed therethrough for dispensing contents of the tube from the tubular container by pressure on the wall of the tubular body.
  • a peripheral sealing portion of the head portion is secured to the tubular body and the head portion has an upwardly extending flange on the head portion that is spaced from the neck, the flange terminating at an upper end.
  • a closure cap is provided that is securable to the neck of the head portion to close off the dispensing orifice, which closure cap has a top wall and downwardly depending skirt which terminates as a bottom edge.
  • the upwardly extending flange is sized such that, upon securement of the closure cap on the neck of the tubular body, the bottom edge of the closure cap is below the upper end of, and within the confines of, the upwardly extending flange on the head portion of the tubular body and hidden from view.
  • an external surface of the downwardly depending skirt of the closure cap is closely adjacent an inner vertical wall of the upwardly extending flange on the head portion of the tubular container.
  • a vertical outer surface of the upwardly extending flange on the head portion of the tubular container may be in the form of various shapes, such as oval, circular, polygonal, such as hexagonal, octagonal or otherwise, or vertically grooved to give a knurled effect, or other shape as desired.
  • the head portion of the tubular container may be of a different color than the cylindrical wall of the tubular body, which will provide a band of the different color of the upwardly extending flange between the tubular body and the flange and, if desired, the closure cap.
  • the present invention provides a collapsible tubular container where the bottom edge of a closure cap skirt, the closure cap used to seal an orifice through the neck of the container, is hidden from view by a protective shoulder formed adjacent the periphery of the head of the tubular body.
  • the tubular body is preferably formed of a thermoplastic polymer such as a high density polyethylene, a low density polyethylene, a polypropylene, a polyester such as polyethylene terephthalate, a polycarbonate, a polyvinyl chloride, or the like.
  • a thermoplastic polymer such as a high density polyethylene, a low density polyethylene, a polypropylene, a polyester such as polyethylene terephthalate, a polycarbonate, a polyvinyl chloride, or the like.
  • the tubular body may be formed from a single layer of thermoplastic polymer or from multi-layers or laminates of various polymers, such as a layer of an oxygen-impermeable material comprising a polyamide, such as nylon, an ethylene polyvinyl alcohol, a polyvinylidene chloride or the like sandwiched between two thermoplastic polymer layers.
  • Five layer compositions may also be used, such as spaced outer layers of polyethylene, polypropylene or polyester, a central layer of an oxygen-impermeable material, and adhesive layers between each of the outer layers and the central layers to bond the same.
  • the tubular body will generally be cylindrical and have a wall thickness of between about 0.010 to 0.040 inch.
  • the collapsible tubular container 1 has a tubular body 3 with a tubular wall 4 and a head portion 5 which are sealed together at one end, or which may be formed as an integral unit.
  • the head portion 5 has a truncated conical portion 6 with a neck 7, the neck 7 extending upwardly from one end of the conical portion and having means for securing a closure cap thereto, such as neck threads 8.
  • the neck 7 is generally coaxial with the tubular body and has a dispensing orifice 9 formed therethrough.
  • the head portion 5 of the tubular body 3 will usually be thicker than the tubular wall 4, and of a thickness of between about 0.035 to 0.045 inch.
  • the tubular wall 4 is formed as a thermoplastic, extruded, longitudinally stretched cylinder and the head portion 5 secured thereto at one end by known processes, such as those described in U.S. 3,047,910 to Downs, U.S. 5,069,856 to Holoubek and Rhoades or other method for sealing a head to a tubular member. With such methods, a peripheral sealing portion of the head portion 5 is secured to the tubular wall 4.
  • an upwardly extending flange 10 is provided on the head portion 5, the flange having inner vertical wall 11, outer vertical wall 12 and an upper end 13.
  • the outer vertical wall 12 may be of any shape desired by the producer, such as a circular shape as illustrated in Figures 1-4, or other shape.
  • the outer wall 12 of the upwardly extending flange 10 may have a plurality of angular segments 12a-12h to form a polygonal shape such as an octagon.
  • the outer wall 12 may have vertical grooves 14 formed therein to provide a knurled affect, such as is shown in Figure 6.
  • the upwardly extending flange 10 is spaced from the neck 7 and also preferably spaced from the periphery 15 of the head portion 5.
  • the closure cap 2 has a top wall 16 and a downwardly depending skirt 17 which terminates as a bottom edge 18.
  • the closure cap has means therein for securement to the neck 7 of the tubular container 1, such as cap threads 19 which are threadably engageable with the neck threads 8 on the neck 7.
  • the downwardly depending shirt 17 has a vertical inner surface 20 and vertical outer surface 21.
  • the bottom edge 18 of the downwardly depending skirt 17 of closure cap 2 is below the upper end 13 of the upwardly extending flange 10 on the head portion 5 of the tubular body 3 and within the confines of the upwardly extending flange 10, and is hidden from view.
  • the outer surface 21 of the downwardly depending skirt 17 of closure cap 2 is closely adjacent the inner wall 11 of the upwardly extending flange 10 of the head portion 5 of tubular body 3.
  • FIG. 7 Another embodiment 1' of the present invention is illustrated in Figure 7, where the tubular body 3 and closure cap 2 are shown assembled.
  • the tubular body as previously described has a tubular wall 4 and head portion 5 at one end, the head portion having a truncated conical portion 6 and neck 7, the neck having threads 8 and an orifice 9.
  • an upwardly extending flange 10 has an upper end or inclined surface 13 which extends from the tubular body 3 upper end 22 upwardly towards the neck 7 and ends at terminus 23, the flange 10 having an inner vertical wall 11.
  • the upwardly extending flange does not have an outer vertical wall, such as wall 12, of embodiment 1, but rather upper end 13 slopes outwardly and downwardly from the vertical inner wall 11 to the peripheral portion secured to the tubular body 3.
  • the bottom edge 18 of a downwardly depending skirt 17 of a closure cap 2 will, upon securement to the container body 3 be below the terminus 23 of the upper end 13 of the upwardly extending flange 10 on the head portion 5 of the tubular body 3 and within the confines of the upwardly extending flange 10, and hidden from view along a horizontal plane.
  • the downwardly depending skirt 17 of closure cap 2 is preferably closely adjacent the inner wall 11 of the upwardly extending flange 10 of the head portion 5 of tubular body 3.
  • a decorative feature that is provided by the present invention lies in the fact that the head portion 5 of the tubular body 3, with the upwardly extending flange 10, may be a different color or texture than the tubular wall 4, in which case a ring of color different than the tubular wall 4, and the same or different than the closure cap 2 will be present to enhance the appearance of the collapsible tubular container 1.
