Definitions

  • TITLE FILLABLE AND/OR REFILLABLE TUBE
  • the invention relates to an improved tillable and/or ref ⁇ llable soft tube which provides for storage and use of various kinds of products such as fluids, lotions, paste, liquids, creams, gels, foams, etc.
  • Soft tubes used for packaging and storage of pharmaceutical, cosmetic and consumer products have been well known.
  • soft tube packaging has been advantageous in the packaging of fluids, lotions, paste, liquids, creams, gels, foams, etc.
  • these products may be packed in soft tubes having the top end closed with various spout and sealing configurations (such as a screw cap, flip cap, foldable nozzle, push button/toggle valve, etc.), while the bottom end is sealed or closed upon itself by rolling, milling, crimping, clamping, or welding.
  • Such tubes may be available in a wide range of sizes and proportions to accommodate different product types and quantities.
  • soft tubes typically tooth paste or sunscreen tubes
  • soft tubes are easily deformable and can be made in small sizes, they are not easily or quickly ref ⁇ llable, especially small sized soft tubes. While it is possible to refill them through their small sized dispensing orifice, doing so is difficult and time consuming since their design is not optimized specifically for the purpose to be easily filled and/or refilled, and/or sealed, and/or resealed by the end user. On the other hand, a large orifice may make it difficult to control the dispensing quantities. The lack of reusability of the tubes also contributes to waste and harm to the environment.
  • Soft tubes for dispensing liquid, semisolid and pasty products have been known (see US3199737, US2718983).
  • soft tubes comprise a dispensing orifice to dispense the contents of the tube.
  • the dispensing end of the tube is generally made to taper, which may provide structural stability as well as provide a smaller dispensing orifice for a more controlled output/dispense.
  • this taper or narrowing of the dispensing orifice for the purpose of a more controlled output makes it poorly suited for filling and/or refilling.
  • Filling is typically done during manufacturing from the bottom end, after which, the bottom end is permanently crimped, folded, or welded closed.
  • EP0806344 relates to a new method to fill a dispenser with cyanoacrylate adhesive from the rear.
  • the container is sealed by a pressed-in base section.
  • US4445609 describes a refillable soft tube that can be filled and/or refilled from the bottom end of the tube, which is closed or resealed by folding the bottom end upon itself after filling and
  • INCORPORATED BY REFERENCE (RULE 20.6) is held closed by a third part, a clip.
  • WO 93/10013 describes a refillable tube container with a screw cap at the bottom end of the tube. While refillable soft tube containers of the prior art (US4445609 and WO 93/10013) advantageously provide adequate refillability and resealability, they commonly suffer from a major disadvantage of the need to essentially include a third part, namely a clip, pin, or screw cap to clamp, wind, or screw closed the bottom end of the tube, (for the clip or pin, folded upon itself).
  • the object of the present invention is to avoid these disadvantages by providing a packaging tube that can be easily and quickly opened, filled and/or refilled, sealed and/or resealed closed by the user, and will not leak.
  • a principal objective of the present invention is to incorporate a large area, sealable and/or resealable opening.
  • Another objective is to provide a fillable/refillable soft tube that can be deformed easily.
