Definitions

  • This invention relates to fold retainers for flexible memoryless dispensing tubes.
  • Flexible dispensing tubes used for dispensing a product, such as toothpaste, through an opening by squeezing the flexible walls of the tube are well known.
  • the flexible tube has an opening at one end and is sealed by a transverse seam at the other end.
  • the contents of the tube are typically dispensed in small amounts and a cap is placed over the opening to preserve the remaining contents.
  • the sealed end is folded against the flexible wall to force the product through the opening.
  • the sealed end of the tube is folded over again. This folding may continue until all of the product is expelled from the tube.
  • the problem of preserving the folded condition of a resilient tube is solved by the present invention which provides a tube having a flexible wall with a fold retainer secured at the sealed end thereof.
  • the fold retainer permits the sealed end to be folded and the folded end encircled by the ring to preserve it in the folded condition.
  • the fold retainer includes a pair of rings attached to one another along a short segment.
  • One ring encircles the sealed end of the tube and is made integral with the tube by a tight fit or is otherwise permanently attached to the tube.
  • the other ring extends away from the tube, and encircles the folds to retain the folded portion of the tube.
  • the fold retainer is integrally formed with the tube. This is accomplished by sealing the tube at one end so an unsealed portion of the tube extends beyond the sealed end.
  • the extending, unsealed portion of the tube is transversely cut to separate it from the tube, except for a short segment thereof.
  • the short segment folds with the tube, while the remainder of the severed tube end, which is in the form of a ring, is used to encircle and hold the folded section.
  • the cut is an arcuate one to increase the diameter of the unattached portion.
  • FIG. 1 is an elevational view of one embodiment of the present invention
  • FIG. 1A is a fragmentary elevational view of an alternative version of transverse cut for the embodiment in FIG. 1,'
  • FIG. 2 is a fragmentary elevational view of another embodiment of the present invention.
  • FIG. 3 is an elevational view illustrating the retaining ring of FIGS. 1 and 2 holding a memoryless tube in a folded condition.
  • FIG. 1 A preferred embodiment of a flexible, dispensing tube that incorporates the principles of the present invention is shown in FIG. 1.
  • the tube 10 includes a tube body 12 having a flexible wall 14 with none or relatively little memory retention characteristics when folded. As previously noted, such tubes are denoted as memoryless tubes for purposes of this disclosure.
  • a shoulder 18 is formed with an opening 20 for dispensing the product from the tube 10.
  • a cap (not shown) may be used to cover the opening 20 to preserve the product housed within the tube body 12.
  • the lower end 22 is closed by sealing the flexible wall 14 along a seam 24.
  • a fold-retainer 26 is integrally joined or secured by a tab 28 to the tube body 12 at the seam 24.
  • the fold-retainer 26 also includes a retaining ring 30 that extends from seam 24 for holding the tube body 12 in a folded condition.
  • the tube of FIG. 1 is formed with the lower end 22 open so the product may be placed within the tube body 12.
  • the lower end 22 is sealed along the seam 24 so that a portion of the tube body 12 extends from the seam 24. Preferably, this extension is about 1/8" though other lengths may be. used.
  • a transverse straight cut across most of the length of the seam 24 separates the fold retainer 26 from the seam 24 except for the tab 28.
  • the cut is arcuate, as shown in FIG. 1A, to form a curved ring 30 that is larger in diameter than the ring formed by the straight cut as depicted in Fig. 1.
  • FIG. 2 Another embodiment of a tube incorporating the present invention is shown in FIG. 2.
  • the tube 10 has a tube body 12 with a shoulder 18 and opening 20 at one end.
  • the seam 24 of this tube is made to terminate the tube body 12 without an extension from the seam.
  • a fold-retainer 34 is made from an elastic material and includes a retaining ring 36 and a securing ring 38 which are attached to each other.
  • the securing ring 38 encircles and is attached to the seam 24 so the retaining ring 36 is free to encircle and retain the tube in a folded condition.
  • the retaining rings 30, 36 of the fold-retainers 26 and 34 are moved out of the folding path until folding of the tube is complete.
  • the retaining ring 30, 36 of the fold-retainers 26, 34, respectively are then moved adjacent the tube body 12 and opened to encircle and hold the tube in the folded condition as shown in FIG 3.
  • the retaining ring may be opened and moved away from the folded portion to permit a further fold of the flexible wall 14 and then returned to the position shown in FIG.4 to secure the tube in its new folded condition.

Abstract

On décrit un garde-pli (26) destiné à un tube souple (10), ne mémorisant pas les pliages et comportant une extrémité soudée (22) et une extrémité ouverte (20) qui permet d'en vider le contenu par pliage de l'extrémité soudée. On fixe à cette fin à l'extrémité soudée (22) du tube (10) un anneau de rétention (30) formé de préférence par le soudage transversal du corps du tube le long d'une couture (24), de manière qu'une courte partie dépasse cette couture, puis par une découpe transversale pratiquée entre ladite couture (24) et l'essentiel de la largeur du tube. La partie non coupée constitue un onglet (28) formant un seul tenant avec l'extrémité soudée (22) du tube (10) alors que la partie coupée forme un anneau de rétention (26) permettant de maintenir le tube plié . De préférence, la découpe prend une forme courbe, ce qui permet d'augmenter le diamètre de l'anneau de rétention (26). Ce garde-pli (26) peut aussi être constitué d'un double anneau. Un anneau (38) entoure l'extrémité soudée (22) afin de garantir la fixation de l'anneau de rétention libre (36) à côté du tube.
