Definitions

  • the present invention relates to a new sheet material that may be located within a light transparent container such that when liquid is introduced therein an illusion is created that the liquid contains bubbles or droplets.
  • the invention also relates to a method of producing such material and its use in transparent containers; so that when the sheet material is immersed in a liquid it reflects and refracts light in a similar way to many individual small gas bubbles rising in such a liquid.
  • Bubble wrap sheet material is commonly used to protect fragile goods during transit, It comprises two layers of thin (typically 0.01 to 0.02mm thickness) polymer sheet with dimples located at regularly spaced intervals over at least one of these sheets. Typically, each of the two layers has the same thickness.
  • the dimples typically cover 70-80% of the material surface. This relatively high proportion of dimples is an important characteristic that is required in order to provide the desired cushioning effect. Normally, individual dimples are not fully inflated with air; this feature combined with the thin wall thickness results in individual dimples each providing a cushioning effect. Exceptionally, when individual dimples are fully inflated a dimpled sheet material with elastic properties will be used in order to provide the desired cushioning effect; by creating in effect many individual inflated "balloons". Thus, bubble wrap does not employ rigid dimples or use dimples covering less than about 70% of the sheet material surface. Disclosure of the Invention

  • a screw cap (303) is then attached [see Figure 53(c)].
  • a floor portion (304) is then attached to the base end of the container; for example using high frequency welding.
  • the container can be filled with liquid before [Figure 64(c)] or after attaching the floor portion.
  • a container base is then attached 0 [ Figure 64(d)] to avoid sharp edges.
  • Figure 65 shows cross-section views of a plastic container manufactured with a step feature (401) [see Figure 65(a)]. This step is then cut out at (402) and (403), dividing the bottle into two portions (404) and (405) being able to form a join by sliding one inside the other. Separate embossed linings are the inserted (406) and (407) 5 through the open ends [see Figure 65 (b)]. Portions (404) and (405) [ Figure 65(c)] are then slotted together, one inside the other, before the seam (408) is heat sealed. The label (409) is then applied around the waist of the bottle to conceal that part of the bottle not containing the embossed lining.
