Definitions

  • This present invention relates to collapsible containers for extrudable viscous fluids
  • viscous fluid products which are generally provided in flexible wall containers with a reclosable nozzle.
  • Such products include toothpaste, cosmetics, ointments, artists pigments, adhesives, sealants and greases and lubricants and even food and condiments.
  • These containers come in a variety of shapes and sizes but are generally known as collapsible tubes. These tubes are generally cylindrical over most of their length with a sealed or folded closure at one end. At the other end is a nozzle arrangement generally with a reclosable lid.
  • the tubes are generally made of a flexible material which is usually plastic, laminate, metal or a combination of these materials, but other materials may be used.
  • the material of the tube is deformable in order to allow the contents of the tube to be squeezed through the nozzle. This deformation may be inelastic as is the case for metal tubes or elastic for plastic tubes.
  • the material of the shoulder is generally more rigid than that of the body of the tube in order to provide sufficient support for the nozzle and reclosable lid.
  • collapsible tubes have been very successful in providing a clean and simple dispensing method.
  • the contents are generally required in quantities which are small compared to the capacity of the collapsible tube.
  • the nozzle which is generally small in comparison to the cross section of the tube, provides good control for the dispensing of such small amounts.
  • the tube is not designed to be cut and the instruments chosen by a consumer on the spur of the moment with which to cut the tube are often inappropriate.
  • the tubes are designed to withstand significant pressure in squeezing and may be difficult to cut. The outcome is generally unsatisfactory and may well lead to injury for the consumer.
  • a collapsible tube of a type adapted to dispense viscous fluid products having a flexible hollow tube body, a nozzle and a reclosable lid for said nozzle, wherein there is means incorporated into said body for creating a secondary opening, said opening being larger than the opening of the nozzle.
  • the secondary opening means includes at least one weakened area of the tube wall.
  • the means for forming a secondary opening further includes a tear strip and a pull tab.
  • the tear strip and the pull tab may be integrally formed with the tube wall.
  • all or part of one or both of the pull tab and the tear strip may be formed of a different material, or by a different means , to the wall.
  • the tear strip is adapted to be removed by applying force to the pull tab, thereby separating the tube into two sections.
  • the invention may be said to lie in a method for accessing the residual contents of a collapsible tube, including the steps of providing means adapted to form a secondary opening in the tube, then at such time as it becomes inconvenient to squeeze the contents of the tube through the nozzle, operating said means to form a secondary opening in the tube, and accessing the residual contents through said opening.
  • Figure 1 a-c shows a collapsible tube of the present invention with a tear strip in as- supplied and operated modes
  • Figure 2a-b show detail views of the tear strip of the embodiment of Figure 1 ;
  • Figure 3a-c shows a second embodiment of the invention with the tear strip in an as-supplied and operated mode
  • Figure 4a-b shows a detail of the tear strip of the embodiment of Figure 3;
  • Figure 5a-b shows a preferred embodiment of the invention wherein the secondary opening is reclosable
  • Figure 6a-c shows detail of the secondary opening of the embodiment of Figure 5.
  • FIG. 1 there is a collapsible tube 1 , with a removable and collapsible lid 2. This lid is removably attached to a nozzle (not shown). The collapsible tube is sealed at the end distal from the lid by a foldover seal 3.
  • the side wall of the tube includes two weakened regions 5 which define a portion of the side wall which forms a tear strip 4. This tear strip extends beyond the tube wall to form a pull tab 6.
  • Figure 2a shows a cross section through a detail of the point at which the pull tab 6 meets the side wall 10 of the tube 1.
  • Figure 2b shows this same detail not in cross section.
  • the tab 6 can be seen meeting the tear strip 4.
  • the tear strip is defined by weakened regions 5 which appear here as shallow grooves.
  • the tube as shown in Figurela is used normally until such time as the remaining contents of the tube become difficult to force through the nozzle. At this point the user may grip the pull tab 6 and pull to separate the pull strip 4 from the tube wall 10. This is shown in Figure 1b.
  • Figure 3 shows a collapsible tube 30 with a reclosable lid 31 which closes onto a nozzle (not shown).
  • the collapsible tube is sealed at the opposite end to the lid by a fold over seal 32.
  • tear strip 33 There is provided a single weakened section in the side wall of the tube in the form of a tear strip 33. This tear strip is integrally connected to pull tab 34.
  • the tear strip, the pull tab and the tube wall may be of the same or different materials.
  • the tear strip may be formed integrally with the tube wall, being defined by the weakened wall section.
  • the tube may be pre-cut, with the sides of the cut being abutted to each other.
  • the tear strip may then be formed or attached to seal the cut ends, forming a continuous tube.
  • the tear strip in this case, may be attached to the tube walls by heat welding, adhesive, or any other suitable means.
  • Figure 4a is a section view of Figure 4b shows a side wall of the tube 30 at the point where the tab 34 meets the side wall.
  • Figure 4b shows the same detail not in cross section. It can be seen that the pull tab 34 is much broader than the tear strip 33 in order to facilitate the user gripping this tab in order to remove the tear strip and separate the portions of the tube.
  • the embodiments so far disclosed are best adapted for use when the amount of product remaining in the tube at the point at which the secondary opening is created is relatively small, ideally only that amount required for a single use.
  • the viscosity of the product and the stiffness of the tube mean that a substantial portion of the product remains in the tube at the point at which it becomes no longer convenient to force the contents through the nozzle.
  • the secondary opening it is advantageous for the secondary opening to also be reclosable.
  • this reclosable connection should be of the same sealing quality as that of the primary reclosable lid.
  • Figure 5 shows a collapsible tube 50 with a primary reclosable lid 51 which closes onto a nozzle (not shown).
  • a tear strip 52 Incorporated in the side wall of the tube is a tear strip 52 defined by weakened regions 53 and 54. This tear strip ends in a pull tab 55.
  • the pull tab 54 When access to the remaining contents of the tube is required of the pull tab 54 is pulled and the tear strip 52 pulled away from the body of the tube.
  • the tube is then divided into two portions 56 and 57.
  • the contents of the tube are then freely accessible via openings 58 in these two tube portions.
  • the removal of the tear strip also exposes the mating of structures 59 and 60 which are formed into tube portions 57 and 56 respectively. These portions are then able to be deformed under light pressure in order to be interlocked. The two portions 56 and 57 are thus releasably reengaged. The remaining contents of the tube are thus protected to some extent from exposure and spillage.
  • the tear strip may be formed integrally with the tube wall, being defined by the weakened wall section. Alternatively, the tube portions and the mating portions may be pre-formed, with the mating portions being engaged. The tear strip may then be formed or attached to seal the mating portion, forming a continuous tube. The tear strip in this case, may be attached to the tube walls by heat welding, adhesive, or any other suitable means.
  • Figure 6a is a cross section view of the side wall of a tube of embodiment as shown in Figure 5. It can be seen that the interconnection structures 59 and 60 are engaged whilst the tear strip 52 is placed and once the tear strip is removed as in Figure 6b they may then be easily disengaged and reengaged as shown in Figures 6b and 6c.
  • the tear strip in each of the described embodiments may be of the same material as the tube wall and may be integrally formed therewith, with the weakened section defining the pull strip. Alternatively, it may be of a different material, or formed separately, from the tube wall.
  • the tear strip is formed of a different material to that of the tube wall. This material is stronger than the material of the tube wall.
  • the tube wall is plastic and the tear strip includes a metal strip. No weakened portion of the tube wall is provided. The tear strip is removed to allow access to the contents of the tube, as in any of the previously described embodiments . The greater strength of the material of the tear strip allows it to be separated from the tube wall, without requiring weakened portions.
