  • This singleuse bag assembly is particularly useful in the food delivery service industry since the size of the vent or vents, while providing venting of steam for example, is sufficiently small so that delivery personal cannot tamper with the bag contents without tearing of the bag or seal.
  • the delivery bag assembly 20 includes a fairly conventional handled bag assembly with the sheet- like first panel 21 and the opposed sheet-like second panel 22 either directly joined at the opposed panel side edges 44, 47 and 48, 49, forming common opposed side seams (not shown) or joined at respective panel side edges by an opposed pair of sheet-like, vertically creased, side gussets 23, 25 therebetween.

  • the bag assembly 20 includes an elongated, single-sided adhesive or tape member 30 mounted to the exterior surface, and at the first and second edges 31, 32 of either the sheet-like first and second panel 21, 22.
  • the tape member will be described with reference to mounting, initially, only to the exterior surface of the first panel 21, although it will be appreciated that the tape member could be mounted to the exterior surface of the second panel 22 or to either interior surfaces thereof.
  • the elongated tape member 30 is initially adhered or mounted to the exterior surface of the first panel 21, extending laterally along the corresponding upper first edge 31 thereof.
  • the tape member 30 In general, less than about one -half of the tape member 30 (i.e., a lower lateral portion thereof) is positioned below the corresponding first edge of the first panel 21, while being mounted to exterior surface thereof.
  • the remaining upper lateral portion of the tape member 30 extends above the corresponding first edge 31, in the unsealed condition (FIGURES 1-6), and is initially not mounted or adhered to anything other than its protective strip 33.
  • the height of the lower lateral portion (mounted to the exterior surface of the first panel 21) and that of the upper lateral portion of the tape member 30 are generally equal to one another.
  • the height of the upper lateral portion may be significantly higher than that of the lower lateral portion.
  • the height of the lower lateral portion may be Vi while that of the upper lateral portion is 11 ” above the first edge 31.
  • the remaining upper lateral portion of the tape member 30 is configured to be folded over the opposing second edge 32 of the second panel 22 (FIGURE 5), when the opening 35 into the bag interior of the bag is positioned in a closed condition (FIGURE 6), prior to sealing of the opening in a sealed condition (FIGURES 7 and 8). It will be appreciated that in this closed position, the opposed first and second edges 31, 32 of the sheet- like first and second panels 21, 22, as well as the handles 27, 28, will be oriented generally parallel to and adjacent one another.
  • the upper lateral portion of the tape member 30 includes corresponding handle cutouts 45, 46 aligned therewith. These aligned handle cutouts 45, 46 separate the remaining upper lateral portion into three closure sections 50, 51 and 52, enabling the tape upper lateral portion to be folded over the corresponding second edge 32 of the second panel 22.
  • the exposed adhesive 38 on each closure section of the tape member can be adhered to the corresponding exterior surface of the second panel upper section, thereby sealing the bag closed in a sealed condition (FIGURES 7 and 8).
  • the handle cutouts 45, 46 can be any shape, but must be sufficiently dimensioned to accommodate the lower leg portions 40-43 of the handles 27, 28 when the panel upper sections are oriented in the closed condition and the tape member is in the sealed condition.
  • integral cutout vent apertures 60, 61 into the bag interior are formed by the cutouts themselves when the tape member seals the bag opening (FIGURES 7 and 8).
  • these vent apertures 60, 61 are essentially formed between the interior distal edges of the outer closure sections 50, 52 of the tape member 30 and the first and second edges 31, 32 of the corresponding panels 21, 22.
  • the outer vent apertures 62-65 are formed by the spacing between the outer distal edges of the outer closure section 50, 52 of the tape member 30 and the corresponding opposed side edges of the first and second panels 21, 22, as the tape member extends across roughly about 90% the width of the first and second panels. In this manner, when the outer closure sections 50, 52 of the tape member are sealed against the exterior surface of the second panel 22, the distal ends of the tape member 30 and the end creases of the corresponding folded side gussets 23, 25 form these four outer vent apertures 62-65.
  • vent apertures provide venting of contents sealed within the bag interior. This will of course assures proper steam venting of hot food content therein, for instance, when the bag assembly is being carried by the handles 27, 28. It will be appreciated, however, that each vent aperture or passage is of a lateral dimension sufficiently large to enable adequate venting of steam therethrough while being sufficiently small to prevent the passage of a human hand therethrough.
  • vent apertures are preferably in the range of opening to at least about 3.2 mm in diameter to no more than about 25.4 mm in diameter, and more preferably about 12.7 in diameter.
  • the bag assembly When the tape member 30 is folded over, using the adhesive 38 to seal off the bag opening, the bag assembly is temporarily closed while retaining the container contents in the content receiving region.
  • the adhesive 38 of the tape member will maintain the closure of the bag assembly until forcibly opened and/or torn. Accordingly, a tamper evident seal is created, assuring both the food preparer/provider, the food delivery driver, and the customer that content contained in the bag assembly 20 has not been tampered with.
  • the character and properties of the adhesive of the closure tape member 30 is preferably similar to that of the relatively strong adhesives and adhesive tapes employed for those used on overnight delivery packages, for instance. That is, the adhesive strength must be sufficiently strong so that any attempt to open the sealed bag assembly would show visible signs of tampering (e.g., stretching, tearing, etc. of the bag material and/or closure adhesive).
  • Suitable closure adhesive tape materials include, for example, 3M® 9086, 9888T, CT6348, 9088, 9088FL, and 55256 double-sided adhesive.
  • the tape member 30 includes a manually removable protective strip 33 (FIGURES 1-4).
  • FIGURES 1-4 the adhesive 38 of the closure sections 50, 51, and 52 are protected until needed and utilized.
  • the adhesive when still oriented in the unsealed condition, will not inadvertently contact the exterior surface of the second panel 22 until the tape upper lateral portion is manually folded over the first and second edges of the bag, and sealed against the second panel.
  • a single unit protective strip 33 is applied, spanning the voids created by the handle cutouts 45, 46 of the upper lateral portion of the tape member. In this manner, the protective strip can be removed as one unit rather than removing three separate units. This significantly reduces the time and effort required to remove the protective strip during sealing the bag assembly 20.
  • the tape member 30 includes strategic cuts or scoring 70 (e.g., FIGURES 1, 4 and 16) to easily cause breakage of the tape member should removal of the tape be attempted. Such scoring, thus, easily shows any evidence of tampering due to visual separation of the scored portion of the tape member 30 should tampering of the tape member be attempted.
  • scoring 70 is shown in the figures as a plurality of adjacent S-shaped slits that extend traversely across the tape member, the scoring marks can be provided by any convention designs.
  • the slits may be in the form of designs.
  • more distinctive designs include lettering or the like, and can provide personal advertising such as the “S2G” design (Seal-2-Go) shown in FIGURE 16.
  • the tape member 30, alone may be provided for mounting of the lower lateral portion of the tape member to the upper section 36 of the first panel 21 (FIGURE 16).
  • the tape member would be provided with pre-cut handle cutouts 45, 46 that are to be aligned with the leg portions 40, 41 of the first handle 27.
  • the tape member includes a lower protective cover 34 similar to the protective strip 33 that protects an adhesive mounted to the lower lateral portion (not shown). This protective cover 34 may removed prior to aligned adhered mounting of the lower lateral portion to the first panel upper section 36 without requiring removal of the protective strip 33.
