Definitions

  • the present invention relates to a package for a flow­able material which is susceptible to flavor loss.
  • the use of collapsible tubes for a flowable material, such as dental cream, is known.
  • the tubes normally define a chamber, have a tapered shoulder, and have a neck extending from the shoulder.
  • the tubes are normally constructed from a laminate, such as polyethylene, aluminum foil, paper, and polyethylene. Although the tubes operate satisfactorily in dispensing the material, it has been found that the material is subject to flavor loss in the region of the shoulder.
  • a principal feature of the present invention is the provision of an improved package for a flowable material which is susceptible to flavor loss.
  • the package of the present invention comprises, an elongated collapsible tube defining a chamber to receive the material, with the tube having a tapered shoulder, and with the shoulder having a generally central opening.
  • the package has a separate insert comprising a hollow tubular section received in the opening, with the tubular section having an outer end por­tion located outside of the shoulder, and an inner end portion extending into the chamber.
  • a feature of the present invention is that the inner end portion extends into the chamber a sufficient distance to prevent extrusion of the material in the region of the shoulder which is subject to flavor loss through the tubular section.
  • Yet another feature of the invention is the provision of means for sealingly engaging the shoulder by the tubular sec­tion around the opening in order to close the opening.
  • the insert may be utilized with any type of material for the tube.
  • a further feature of the invention is the provision of means for preventing the insert from turning in the opening to prevent movement of the tubular section while securing or removing a threaded cap onto or from the tubular section.
  • a package gen­erally designated 10 comprising a collapsible tube 12, an insert 14, and a cap 16.
  • the tube 12 has a squeezable or collapsible main body portion 18 defining a chamber 20 to retain the flow­ able material 22 which is susceptible to flavor loss, such as a dental cream.
  • the tube 12 has a tapered shoulder 24, with the shoulder 24 having a generally central opening 26.
  • the tube 12 may be constructed of any suitable material, such as aluminum, or a laminate comprising polyethylene, aluminum foil, paper, and polyethylene.
  • the insert 14 comprises an elongated tubular section 28 which is received in the opening 26, and which is snap-fit into the opening 26 of the shoulder 24.
  • the tubular section 28 has an outer end portion 30 located outside of the shoulder 24, and an inner portion 32 extending into the chamber 20 to a loca­tion past the shoulder 24.
  • the tubular section 28 has an outer annular outwardly directed tapered blade 34 sealingly engaging against an outer surface of the shoulder 24 around the opening 26, and an inner annular outwardly directed tapered blade 36 sealingly engaging against an inner surface of the shoulder 24 around the opening 26.
  • the tubular section 28 has a lumen 38 extending through the tubular section 28 in order to permit passage of the material 22 through the tubular section 28 to the outside of the package 10.
  • the outer end portion 30 of the tubular section 28 has outer threads 40, as shown.
  • the cap 16 has inner threads 42 which cooperate with the threads 40 of the tubular section 28 in order to releasably secure the cap 16 onto the insert 14 and close the lumen 38.
  • the shoulder has a plur­ality of serrations 44 disposed around the opening 26 which frictionally engage against the tubular section 28 intermediate the blades 34 and 36 in order to prevent turning of the tubular section 28 in the opening 26 while securing the cap 16 to the tubular section 28 and removing the cap 16 from the tubular section 28.
  • the tubular section 28 may be constructed from a suitable plastic material, such as high density polypropylene or nylon, which does not casue flavor loss in the material 22.
  • the outer surface of the tubular section 28 in contact with the shoulder may also have a serrated surface or matted finish to assist in the frictional retention during rotation.
  • the cap 16, may also be of the captive or flip-top type.
  • the tubular section 28 may be secured to a tube 12 of any type material, as desired.
  • a material is utilized in the tube 12 which causes flavor loss in the region of the shoulder 24 of the tube 12
  • the inner end portion 32 of the tubular section 28 prevents extrusion of this material adjacent the shoulder 24 through the tubular section 28 and outside of the package 10, thus eliminating the dispensing of material 22 which is subject to flavor loss.
