Technical Field

[0003] The present invention relates to tote bags, and more particularly, the present invention relates to grocery and food service, sealable bags with integrated note tabs. Background Art

[0004] Traditional lunch bag shaped paper bags have been used in the food industry since at least the beginning of take-out fast food services. These open-top paper bags are easy to open, fill and close, allowing for simple access to their contents.

[0005] Recently, paper and plastic tote bags have become more commonly used for food delivery. While the use of these paper and plastic tote bags continues to proliferate in the food service industry, especially recently with the growth of third-party food delivery services, the potential for food tampering has also increased. Both the food preparer / provider and the consumer desire assurance that the prepared food has not been touched or tampered with in any way prior to delivery, as well as assurance to the consumer that the consumer has received the correct delivery without having to immediately open the sealed delivery bag.

[0006] It would therefore be desirable to provide a paper or plastic delivery bag that can be sealed so that the end consumer can be assured that the bag has not been opened and the food prepared therein has not been tampered with. It would also be desirable to provide a sealed bag assembly to which a note such as a purchase receipt, order slip, pick-up slip, etc. can be easily attached for easy viewing of order information, e.g., order number, consumer identification, order contents, purchase price, date and time, etc. Summary of the invention

[0050] Although the present invention will be described with reference to several specific embodiments, the description is illustrative of the present invention and should not be construed as limiting the present invention. Various modifications may be made to the preferred embodiments by those skilled in the art without departing from the true spirit and scope of the present invention as defined by the appended claims. It will be noted that, for better understanding, the same components are represented by the same reference numerals throughout the various drawings.

[0051] Now go to Figures 1 to 10 , a tamper-resistant dispensing bag assembly is provided, generally indicated at 20, having a first sheet panel 21, an opposing second sheet panel 22, and a bottom gusset 23. Each of the first panel 21 and the second panel 22 has an inner surface and an outer surface, the inner surface facing the opposing panel. In addition, each panel 21, 22 also includes a respective upper segment 25, 26, the second upper segment 26 terminating at a second upper edge 27 and the first upper segment 25 terminating at a first upper edge 28 ( Figure 4 , Figure 5 and Fig.10 ), the respective upper segments 25, 26 are defined by a lower set of parallel perforations 30, which will be described in more detail later in this specification. The first edge 28 and the second edge 27 cooperate to define the bag opening 31 ( Figure 4 and Fig.10 ) is at least partially confined to a content receiving area extending between the bag opening 31, the panels 21, 22 and the bottom gusset 23. The upper sections 25, 26 are removable in the open state ( Figure 4 , Figure 5 and Fig.10 ) and closed state ( Figures 7 to 9 ) so that the first edge 28 and the second edge 27 are generally oriented in an opposite, adjacent relationship to each other. The bag assembly also includes a first handle 32 mounted to the upper section 25 of the first panel 21, and the bag assembly includes a pair of spaced-apart first leg portions 33, 35 upright from the first edge 28. The bag assembly also includes a second handle 36, which is mounted to the second upper section 26 of the second panel 22, and also includes a pair of spaced-apart second leg portions 37, 38 upright from the second edge 27. When the upper sections 25, 26 are oriented in the closed state, the first leg portions 33, 35 and the second leg portions 37, 38 are generally aligned adjacent to each other ( Figures 7 to 9 ).

[0052] According to the invention, the upper section 25 of the first panel 21 comprises an upper transverse portion 39 which is integrally formed with the first edge 28 in the unsealed state and extends transversely thereover ( Figures 1 to 6 At the distal portion of the upper transverse portion 39, a closing adhesive 40 is arranged on its inner surface facing the second panel 22 when in the unsealed state. Figure 5 and Figure 6 The upper transverse portion 39 includes a pair of substantially V-shaped handle cutouts 41, 42 ( Figure 1 , Figure 2 , Figure 4 and Figure 5 ), which are neatly aligned with the corresponding leg portions 33, 35 of the first handle 32, and taper laterally outward from near the first upper edge 28 to the distal edge 43 of the upper transverse portion 39. A removable protective strip 45 is provided, which covers the adhesive 40 and spans the handle cutouts 41, 42. When the protective strip 45 is removed and the panel upper sections 25, 26 are aligned in the closed state, the integral upper transverse portion 39, which is essentially divided into three closed sections 47 to 49, can be folded over the second edge 27 of the second panel 22 so that the adhesive 40 contacts the outer surface of the second panel 22, thereby substantially sealing the bag opening in the sealed state ( Figures 7 to 9 ). In this arrangement, the leg portions 33 , 35 and 37 , 38 of the first and second handles 32 , 36 are received by respective V-shaped handle cutouts 41 , 42 of the integral upper transverse portion 39 .

[0053] Thus, a tamper-resistant dispensing bag assembly is provided that can be once-sealed so that if someone attempts to access its contents, visible signs of tampering and tampering are present. Such a bag assembly is particularly useful in the grocery and food delivery service industries.

[0054] Return to reference Figures 4 to 6, the dispensing bag assembly 20 comprises a fairly conventional tote bag assembly in which a first sheet panel 21 and an opposing second sheet panel 22 are either directly joined at opposing panel side edges to form a common opposing side seam (not shown) or joined at the respective panel side edges by side gussets 50, 51 with a pair of opposing sheet vertical folds therebetween. A folded sheet bottom gusset 23 is coupled to the bottom edges of the first and second panels 21, 22 and to the bottom edges of the opposing side gussets 50, 51. The respective inner surfaces of the first and second panels 21, 22, the side gussets 50, 51 and the bottom gusset 23 collectively define a content receiving area of ​​the bag assembly. In addition, the pair of opposing handles 32, 36 are preferably provided by conventional twist ring handles, flat plastic or paper folding handles, rope handles, etc., which are widely available for easy carrying. Each of these handles 32, 36 includes a pair of leg portions 33, 35 and 37, 38, which are mounted to the corresponding inner surfaces of the corresponding upper sections 25, 26 of the first panel 21 and the second panel 22 (for example, Figure 4 and Figure 5 ) or outer surface (not shown).

[0055] In short, it will be appreciated that while the present invention is particularly applicable to conventional paper tote bags, such tamper-evident seal assemblies may be applied to plastic bags as well as any other conventional bag material used in the food distribution industry. Suitable plastic materials include polyethylene terephthalate (PET or PETE), high density polyethylene (HDPE), polyvinyl chloride (PVC or vinyl), low density polyethylene (LDPE), polypropylene (PP), polystyrene (PS or Styrofoam), nylon, polycarbonate, polyamide, polyurethane, and polyoxymethylene. Furthermore, while the present invention is illustrated as a bag assembly having two handles, one mounted on each panel, it will be appreciated that the present invention is applicable to bag assemblies having only a single handle (e.g., only a single handle 32 mounted to the first panel 21 without a second handle 36 mounted to the second panel 22, such as Fig.29 and Fig.30 In addition, Fig.13 As shown, the concepts described below can even be applied to bags without handles.

[0056] In sealing the opening in a sealed state ( Figures 7 to 9 ), when the opening 31 into the bag interior of the bag is positioned in the closed state ( Figures 7 to 9 ), the upper transverse portion 39 of the first panel 21 is configured to be folded over the opposing second edge 27 of the second panel 22. It will be appreciated that in this closed position, the opposing first and second edges 28, 27 of the first and second sheet panels 21, 22 and the handles 32, 36 will be oriented generally parallel to and adjacent to each other ( Figures 6 to 9 ).

[0057] Return to reference Figure 1 , Figure 2 and Figures 4 to 9 In order to accommodate the lower leg portions 33, 35, 37, 38 of the opposing handles 32, 36 mounted to the corresponding first and second panels 21, 22, the upper transverse portion 39 includes corresponding substantially V-shaped handle cutouts 41, 42 aligned therewith. These aligned handle cutouts 41, 42 divide the upper transverse portion 39 into three independently foldable closed segments 47, 48 and 49, allowing the upper transverse portion 39 to be folded over the corresponding second edge 27 of the second panel 22 regardless of the lower leg portions of the handle member. Therefore, as will be described in more detail below, once the protective strip 45 is removed ( Figure 5 and Figure 6 ), the exposed adhesive 40 on each closure segment 47, 48 and 49 can be adhered to the corresponding outer surface of the second panel upper segment 26, thereby sealing the closed bag in a sealed state ( Figures 7 to 9 ).

[0058] When the opposing upper sections 25, 26 of the first and second panels 21, 22 are oriented in the closed state, the foldable closure sections 47, 48, 49 each extend sufficiently above the first edge 28 to easily extend and fold over the opposing second edge 27. However, the height of the intermediate closure section 48 is sufficiently less than the interior height of the handle member to pass through it unimpeded underneath. For example, when the interior height of the handle member is in the range of about 2 inches to about 6 inches, the height of the intermediate closure section 48 (and possibly the height of the upper lateral portion 39) is in the range of about 1 inch to about 4 inches above the first edge 28.

[0059] It will be appreciated that the handle cutouts 41, 42 are generally V-shaped and are substantially identical to one another. Therefore, for the sake of clarity, only one handle cutout 41 will be described herein. Figure 1 and Figures 4 to 6 , the V-shaped handle cutout 41 tapers outwardly from the bottom portion 52 of the cutout (near the upper perforation 30) to its upper distal edge 43. The slope or angle of the handle cutout 41 is determined by the opposite tapered edges 53, 55 of the outer closed segment 47 and the adjacent intermediate closed segment 48, respectively. Preferably, the angles of the tapered edges 53, 55 with the bisecting vertical axis are in the range of about 1 degree to about 60 degrees, and more preferably, in the range of about 5 degrees to about 45 degrees. However, the angles of the tapered edges 53, 55 do not have to be equal.

[0060] These tapered edges 53, 55 create a wider opening into the handle cutout 41 to accommodate the receipt of the aligned leg portions 33, 37 of the handles 32, 36, respectively. As a result, contact of any portion of the closure segments 47 and 48 (and more specifically the closure adhesive 40 of the closure segments 47 and 48) with any portion of the handles 32, 36 is significantly reduced, if not eliminated, when the closure segments are moved to the sealed condition. This is beneficial because any unintentional contact of the closure segment adhesive 40 with the handles 32, 36 while sealing the bag assembly has been found to leave adhesive residue on the handles. Additionally, during the folding movement toward the sealed condition ( Figures 7 to 9 ), the intermediate closed section 48 can more easily pass through the handles 32, 36 without hindrance.

[0061] It will also be further understood that the width of the narrow bottom portion 52 of the handle cutout 41 can be sized and dimensioned to more closely receive the aligned leg portions 33, 35 and 37, 38 of the handles 32, 36 when in a sealed state. Thus, a better seal is formed around the aligned leg portions 33, 37, the bottom portion 52 of the handle cutout 41, and the first and second edges 28, 27 of the respective first and second panels 21, 22 ( Figure 7 and Figure 8 ). By providing a better overall seal of the bag assembly opening, tamper access to the content receiving area is significantly reduced, even if not eliminated prior to the sealing closure segment being compromised.

[0062] To prevent accidental closing or contact of the closing adhesive 40 on the closing sections 47 to 49, the upper transverse portion 39 comprises a manually removable protective strip 45 ( Figure 1 and Figures 4 to 6 ). The single protective strip 45 covers the adhesive 40 and horizontally spans the gap created by the V-shaped handle cutouts 41, 42 of the upper lateral portion 39. In this way, the protective strip 45 can be removed as a single unit, rather than removing three separate units. This significantly reduces the time and effort required to remove the protective strip 45 during sealing of the bag assembly 20.

[0063] Since the adhesive 40 of the closure sections 47, 48 and 49 is protected by the protective strip 45, the adhesive 40 can be exposed by removing the protective strip 45 as needed. However, typically, even when the protective strip 45 is removed from the upper lateral portion 39 ( Figure 5 and Figure 6 ), the adhesive 40 will also not inadvertently contact the outer surface of the second panel 22. This will only happen when the first edge 28 and the second edge 27 of the first panel 21 and the second panel 22 are oriented in the closed state ( Figure 8). Subsequently, the closure segments 47 to 49 of the upper transverse portion 39 can be independently folded over the second edge 27 of the second panel 22. To seal the bag assembly 20, the closure adhesive 40 of each closure segment 47 to 49 is pushed into contact with the outer surface of the second panel 22, thereby sealing the bag opening in the sealed state ( Figures 7 to 9 ).

[0064] Thus, the bag assembly 20 is temporarily closed while retaining the contents in the content receiving area. The closure adhesive 40 of the upper transverse portion 39 will maintain the closure of the bag assembly 20 until it is forced open and / or torn. Thus, a tamper-evident seal is created, ensuring that both the food preparer / provider and the consumer know that the contents contained in the bag assembly 20 have not been tampered with.

[0065] For example, the properties and performance of the adhesive of the upper lateral portion 39 are preferably similar to the properties and characteristics of relatively strong adhesives and adhesive strips used on overnight delivery packaging. That is, the adhesive strength must be strong enough so that any attempt to open the sealed bag assembly will show visible signs of tampering (e.g., stretching, tearing, etc. of the bag material and / or closure adhesive). Suitable closure adhesive strip materials include, for example, 3M ® 9086, 9888T, CT6348, 9088, 9088FL and 55256 double-sided tape.

[0066] In one configuration, to facilitate switching from a closed state ( Figure 7 and Fig. 9 ) To open the bag assembly 20, a pull tab 56 having a grip tab 71 is provided at one end or both opposite ends of the connecting seam 57 between the first upper section 25 and the upper transverse portion 39 of the first panel 21. A plurality of perforations 30, score marks, cuts, etc. are created at the connecting seam 57 to help tear the connecting seam 57 when sufficient force is applied to the pull tab 56 ( Fig. 9 Preferably, a pair of parallel perforations 30 are provided (for example, Figure 1 to Figure 2 , Figures 4 to 6 and Fig.11 ), the pair of parallel perforations 30 generally extend along the longitudinal axis of the connecting seam 57. Fig.10 ) is completely separated from the bag assembly or by merely cutting a row of perforations, the bag assembly can be moved to an open position to access the contents. Of course, it will be appreciated that if tampering with the upper transverse portion 39 is attempted, any unauthorized breaking or tearing of the perforations 30 will readily reveal any evidence of tampering due to the visual separation of the score or perforations.

[0067] In some embodiments, the elongated plastic strip 59 ( Figure 2 , Figure 5 and Figure 6 ) may be arranged and adhered to the back of the connecting seam 57. The strength of the plastic strip 59 is much stronger than the strength range of the heavy paper used in most traditional paper bags, thereby allowing the plastic strip 59 to tear the connecting seam 57. Therefore, due to the sturdiness of this plastic strip 59, perforations 30 or scores may not be necessary, or may only need to be provided near the pull tab 56 to promote the start of tearing of the connecting seam 57 ( Fig.11 ). In addition, prior to any use or sealing of the bag, pulling tab 56 can be used to remove upper transverse portion 39 from the bag assembly, reverting the invention to a conventional tote bag. Alternatively, strap 59 need not be formed of plastic, but rather of a stronger material than that of panel 21 that is designed to tear the material of panel 21, such as heavier paper and fibers formed of nylon, cotton, etc.

[0068] As in Figure 1 and Figures 6 to 11 As best seen in the top transverse portion 39, each of the closure segments 47 to 49 of the upper transverse portion 39 includes a tamper-evident V-shaped score 85 to present minimal evidence of tampering. While the closure segments 47 to 49 fully seal the opening of the closed bag assembly in the sealed state, one can always carefully manipulate and expel one or more of the closure segments back to the unsealed state to gain access to the bag opening and then reseal the closure segments. While there would be only slight evidence of tampering, an unsuspecting customer might not even notice. Thus, as will be described in more detail below, the V-shaped score 85 will easily tear or rip, or even partially tear the score 85, even if only by a small amount, clearly indicating evidence of tampering.

[0069] In another aspect of the invention, one of the outer closure segments 47, 49 includes a note tab 58a configured to hold a note 60 ( Figure 7 and Figure 8 ) or the like (e.g., a purchase receipt, order form, or bill of lading) is secured to the bag assembly 20. This is very beneficial because in one example, the note 60 can be easily adhered to a designated bag assembly for easy viewing of information, such as bag contents, customer identification, order number, and shipping destination, especially when the bag assembly 20 has been sealed.

[0070] The corresponding outer closure segment 47 includes a dividing slit 61 that divides the closure segment into two portions, one of which creates a note tab 58a. Although any dividing portion of the closure segment 47 can be employed as a note tab, it is preferred to use the innermost dividing portion that is closer to the aligned leg portions 33, 37 and 35, 38 of the handles 32, 36. In addition, although the slit 61 can be generally located anywhere along the corresponding outer closure segment to determine the width of the note tab 58a, the slit 61 should at least be located along the upper distal edge 43, rather than, for example, along the inwardly tapered edge 53 ( Figure 5 and Figure 6 ). For example, the width of the note tab 58a generally ranges from about ¼ of the width of the corresponding closure segment to up to about ¾ of its width. In addition, while the slit 61 is shown as being substantially perpendicular to the connecting seam 57, it will be understood that this need not be the case.

[0071] Note tab 58a also includes the same closure adhesive 40 disposed on its inner surface ( Figure 5 and Figure 6 Initially, when the protective cover 45 is removed from the closure adhesive 40 and the closure segments 47 to 49 are adhered to the second panel 22 in the sealed state, the note tab 58a will not be adhered to the second panel 22 in the unmounted state ( Figure 7 ). The note 60 can then be placed between the corresponding closure adhesive 40 of the note tab 58a and the outer surface of the second panel 22 ( Figure 7 ), and the note tab 58a can be pushed into adhesive contact with the note in the installed state ( Figure 8 ). The note tab 58a is typically only used to attach to the note 60 and not to the surface of the second panel 22. Therefore, when the grip tab 71 is grasped, the pull tab 56 is removed along the connecting seam 57 (substantially along the perforation 30), and the note tab 58a and the installed receipt or note 60 are removed, such as Fig. 9 and Fig.10 shown.

[0072] Similarly, the vertical height of the note tab 58a can vary in length, but too little height will render the tab unusable because it will make it difficult to position and adhere the note between the tab adhesive and the second panel 22. On the other hand, a note 58a of too great a height is impractical to use and wastes paper resources. Preferably, the vertical height of the note tab 58a is the same as the vertical height of the closure segments 47 to 49 to simplify manufacturing. Therefore, as described above, the height of the closure segments is preferably in the range of about 1 inch to about 4 inches.

[0073] Return to reference Figure 3 , Figure 4and Figure 5 In the preferred embodiment, a plurality of small vent holes 63 may be provided in the first and second panels 21, 22 and / or in the side gussets 50, 51. The vent holes 63, shown as circular, may be of almost any shape or score. Such venting allows steam or the like to escape from the hot food container to prevent the sealed bag assembly from over-expanding or the contained food from becoming too moist.

[0074] In most cases, only one note tab 58a is incorporated along one of the outer closure sections 47, 49 ( Figures 1 to 10 However, if desired, the note tab 58b may also be formed by the intermediate closure section 48 ( Fig.12 ) is provided. Thus, a middle slit 62 will be provided, and the function of the corresponding note tab 58b will be similar to that of the note tab 58a. In an alternative embodiment, two tabs 58a, 58b may be used to secure multiple notes or a larger note ( Fig.12 ).

[0075] In yet another alternative embodiment, Fig.13 As shown, the bag assembly 20 may be handleless, although its function is the same as that of the above-described embodiments.

[0076] The bag assembly 20 is particularly suitable for manufacturing from a roll of paper or a single sheet of paper. In this particular embodiment, the pull tab 56 is positioned in the first upper section 25 of the first panel 21 and is integral therewith ( Fig.14 ). Fig.14 , Fig.23 and Fig.24 As best shown in FIG. 1 , when in the unsealed state, the pull tab 56 is oriented below the upper transverse portion 39, rather than being positioned in and integral with the upper transverse portion 39 (which is Figures 1 to 11 features of the embodiment shown).

[0077] A horizontal pre-folding line 70 ( Fig.14 , Fig.19 , Fig.23 and Fig.24 ), the upper perforation 30 acts as a dividing line between the first upper section 25 of the first panel 21 and the bottom of each closure section 47 to 49, allowing each closure section to be folded over the second edge 27 of the second panel 22 so that the adhesive of each closure section can contact the outer surface of the second panel 22, thereby substantially sealing the bag opening in the sealed state ( Fig. 20 , Fig.21 ).

[0078] As mentioned above and as Figures 1 to 13In the previous embodiment shown, the pull tab 56 and corresponding perforation 30 have been positioned in and integral with the upper transverse portion 39. While there are many advantages to placing the pull tab 56 there, such as convenience and ease of access to the pull tab, the fold line at the base of the closure segments 47 to 49 coincides with the upper perforation 30a, which facilitates folding at the second edge 27 of the opposing second panel 22. In addition, either fold line can sometimes weaken one or more of the perforations 30a, 30b, causing them to open prematurely or partially tear.

[0079] Return to reference Fig.19 , when the first upper section 25 of the first panel 21 and the second upper section 26 of the second panel 22 are aligned adjacent to each other in the closed state with the bag opening closed, the upper perforation 30a of the pull tab 56 is oriented directly below the opposite second edge 27 of the opposite second panel 22. However, the prefold line 70 is even oriented vertically at or directly above the second edge 27 of the second panel 22. This relative vertical orientation of the prefold line 70 and the upper perforation 30a relative to the second edge 27 promotes the folding of the closure sections 47 to 49 on the second edge 27 toward the sealed state ( Fig. 20 and Fig.21 ), ideally without wrinkling or folding the upper perforation 30a. Of course, this is due to the fact that the second edge 27 is vertically positioned just above the upper perforation 30a for contact in the closed state and will move the closed section to the sealed state. In a particular configuration, when the upper perforation 30a is aligned with the second edge 27 of the opposing second panel 22 in the closed state, the upper perforation 30a will be within a range of about 1 mm to about 10 mm below the second edge 27 of the opposing second panel 22, while the pre-fold line 70 will be within a range of about 0 mm to about 10 mm above the second edge in the closed state. It will be understood that a plurality of pre-fold lines that are parallel and adjacent to each other may be included.

[0080] It is becoming increasingly common for state and / or municipal legislatures to enact local ordinances that prohibit the use of disposable plastic bags. Therefore, it is also not preferred to use any plastic material in the paper container construction, for example, adding a plastic reinforcing backing in the pull tab, which facilitates tearing of the paper bag or carton. Therefore, when designing a functional pull tab 56 for a bag assembly stamped from a roll or a single sheet of paper without using any additional pulling force, it is determined that three factors are primarily considered. These variables are the weight of the paper (e.g., GSM), the vertical width of the pull tab 56, and the perforation design.

[0081] The paper typically employed by grocery style paper bags and those used in the fast food or takeaway industry has a strength greater than that of copy paper. Typical paper weights for bags in the takeaway food industry are typically in the range of 90 GSM to 110 GSM.

[0082] Thus, for paper selected within the range between about 40 GSM and about 150 GSM, more preferably within the range of about 70 GSM to 140 GSM, and most preferably within the range of about 90 GSM to 110 GSM, the vertical width ( Figure 24 to Figure 26 W V ) is in the range of about 3 mm to about 15 mm. It has been observed that if the width W of the pull tab 56 is V Too narrow, then the pull tab can tear the inside of the perforated line prematurely before completing the removal of the entire pull tab. In addition, the pull tab can be difficult to grasp and have an adverse effect on its structural integrity.

[0083] On the other hand, if the vertical width W V Too wide, uniform tearing along the perforations will be compromised again. In addition, if the vertical width is too wide, unnecessary waste paper and increased costs will result. In addition, the handle patch on the inside of the bag will be touched, resulting in a lower handle position and the handle length will be too short to carry.

[0084] Now refer to Fig.25 , describes in detail an embodiment of an upper perforation 30a design and a lower perforation 30b design. In this embodiment, with respect to the upper perforations 30a and the lower perforations 30b, to promote clean, continuous and uniform tearing along the perforation line, each individual perforation slit 72a, 72b includes a horizontal portion 73a, 73b and an inwardly extending inclined portion 75a, 75b that intersects the left distal end of the horizontal portion. It will be understood that "extending inwardly" means that the inclined portions 75a, 75b extend inwardly to the center of the pull tab 56, rather than extending outwardly away from the pull tab 56. It will also be understood that in the illustrated embodiment, the inclined portions 75a, 75b intersect the left distal end of the horizontal portions 73a, 73b because the pull tab 56 is intended to be pulled by the user in a direction from left to right. In other embodiments, the inclined portions 75a, 75b intersect the right distal ends of the horizontal portions 73a, 73b, and the pull tab 56 is intended to be pulled by the user in a right-to-left direction. Each inclined portion 75a, 75b forms an obtuse angle with the corresponding horizontal portion 73a, 73b, preferably in the range of about 135 degrees to about 165 degrees.

[0085] In addition, in Fig.25In the illustrated embodiment, each perforation slit 72b of the lower perforation line 30b is substantially Y-shaped. Each perforation slit 72b also includes an outwardly extending inclined portion 76b, which intersects the left distal end of the corresponding horizontal portion 73b at the same intersection point as the inwardly extending inclined portion 75b. The outwardly extending inclined portion 76b is essentially a mirror image of the inwardly extending inclined portion 75b, forming the same obtuse angle with the corresponding horizontal portion 73b. Therefore, Fig.25 Adjacent perforated slits are shown to provide a stacked appearance and cooperate for directional removal of the pull tab 56 in a single direction from left to right. Correspondingly, only one grip tab 71 ( Fig.23 and Fig.24 ). It will be appreciated that in other embodiments, the angled portions 75b, 76b intersect the right distal end of the horizontal portion 73b, and the pull tab 56 is intended to be pulled by the user in a right to left direction.

[0086] Fig.25 The design of the perforation slits 72a, 72b shown is beneficial for achieving a smooth perforation cut when the pull tab is deployed, wherein the angled portions 75a, 75b extend inwardly of the corresponding horizontal portions 73a, 73b, but away from the tearing direction of the pull tab 56. In this particular embodiment, the substantially Y-shaped slit 72b of the lower perforation line 30b helps prevent the pull tab 56 from tearing when the pull tab 56 is deployed, especially when the pull tab 56 is pulled in a direction that is not parallel to the perforation lines 30a, 30b.

[0087] According to other embodiments, perforation slits of other configurations can be provided.In some embodiments, the perforation slits of both upper perforation line 30a and lower perforation line 30b can be the same type of perforation, wherein the perforation slit of upper perforation line 30a is aligned with the perforation crack of lower perforation line 30b and mirror image.Therefore, according to one embodiment, all perforation slits of upper perforation line 30a and lower perforation line 30b have the design of perforation slit 72a.According to another embodiment, all perforation slits of upper perforation line 30a and lower perforation line 30b have the design of perforation slit 72a.It will be understood that perforation of other designs can also be used.Therefore, according to yet another embodiment, all perforation slits of upper perforation line 30a and lower perforation line 30b simply have horizontal portion.In all these embodiments, plastic strip 59 can be arranged between parallel perforation lines 30a, 30b, so that the operation of pulling lug 56 is used to open bag assembly 20.

[0088] In addition to the paper weight and the vertical width W of the upper and lower perforations 30a and 30b as described above, VAdditionally, the spacing of the perforated slits from one another, the length of the horizontal portions 73a, 73b and their angled portions 75a, 75b, the Y-shaped lower perforated slit 72b and the obtuse angle therebetween all contribute to the ability to successfully and repeatably operate the pull tab 56.

[0089] Thus, where the paper weight GSM range selected for the stamped sheet panel or paper roll of the bag assembly is in the range of at least about 40 GSM to at least about 150 GSM, the preferred perforation slits 72a, 72b have: horizontal portions 73a, 73b having lengths in the range of at least about 0.5 mm to at least about 8 mm; inclined portions 75a, 75b, 76b having lengths in the range of at least about 0.5 mm to at least about 8 mm; and obtuse angles therebetween of at least about 135 degrees to at least about 165 degrees. Finally, the spacing between adjacent perforation slits 72a, 72b is in the range of at least about 0.5 mm to at least about 5 mm. Most preferably, where the selected paper weight is 90 GSM to 110 GSM, the vertical width W between the upper perforation 30a and the lower perforation 30b is 1.5 mm. V The distance between adjacent perforated slits 72a, 72b is about 8 to 10 mm, the distance between adjacent perforated slits 72a, 72b is about 1 mm, the horizontal portions 73a, 73b are about 1 mm, and the inclined portions 75a, 75b, 76b are about 0.5 mm. Finally, the obtuse angle between them is about 135 degrees.

[0090] based on Fig.25 In the perforated design of the embodiment, the pull tab will usually be located on the left side to pull from left to right ( Fig.24 ). If the perforated design is reversed, the pull tab will typically be on the right side to pull from right to left. It will be appreciated that other perforated designs that can be pulled from left to right and from right to left can be implemented.

[0091] To ensure that the pull tab 56 can be removed in an unimpeded manner regardless of the pull tab variant described, the first panel side edge 81 is adhered to the side gusset 50 ( Fig.26) can terminate at a vertical height below the punched pull tab 56. This ensures that when the pull tab is finally removed, the rear portion of the pull tab 56 will not adhere to the side gusset 50. Preferably, the adhesive strip 80 terminates at a distance in the range of at least about 0 mm to at least about 5 mm below the lower perforation 30b, and most preferably terminates at about 0 mm below the lower perforation 30b. In an alternative embodiment, the adhesive strip 80 can extend almost to the height of the perforation line 30a, and there will be such a cut or perforation that is parallel to the longitudinal edge of the adhesive strip 80 and located inwardly from the adhesive strip 80 so that when the pull tab 56 is pulled by the user, the pull tab 56 will be completely torn at the cut or perforation parallel to the longitudinal edge of the strip 80.

[0092] In another configuration, the perforations 30a and 30b may not extend all the way to the gripping tab 71 and the opposite distal end 82 opposite the gripping tab 71. Fig.24 and Fig.26 As best shown in FIG. 1 , the opposite distal end 82 of the pull tab 56 lacks perforations 30a and 30b having a length of at least about 1 mm to at least about 10 mm, and more preferably about 5 mm, in these end gaps 83, 84. This lack of perforations minimizes premature separation of the perforations 30a and 30b at both the grip tab 71 end and the opposite distal end 82 of the pull tab 56.

[0093] and Figures 1 to 11 Similar to the embodiment of the present invention, each of the closure segments 47 to 49 of the upper transverse portion 39 includes a tamper-evident notch 85 to provide minimal tamper evidence ( Fig.14 , Figures 17 to 20 and Figure 22 to Figure 26 ). Although the closure segments 47 to 49 fully seal the opening of the closed bag assembly in the sealed state, one can always carefully manipulate and expel one or more of the closure segments back to the unsealed state in order to access the bag opening and then reseal the closure segments. Although there will be only slight evidence of tampering, an unsuspecting customer may not even notice. Thus, the closure segment score 85 will easily tear or rip, or even partially tear the score 85, even if only by a small amount, clearly indicating tamper evidence.

[0094] Preferably, when in the sealed state, when the closure sections 47 to 49 are folded over and sealed to the second sheet panel 22, the scoring is provided by a plurality of spaced V-shaped scores 85, such as Fig. 20 and Fig. 22However, it will be appreciated that virtually any score shape may be employed. For example, the score may be S-shaped, X-shaped, etc. However, the vertical or substantially vertical score line of score 85 must extend across the underlying adhesive strip 40 and across the lower portion of each closure segment 47 to 49 in the sealing position where there is no underlying adhesive (i.e., that portion of the closure segment is not adhered to the second sheet panel 22 ( Fig. 20 and Fig.26 )). Thus, when the lower distal portion of any one of the closure segments 47 to 49 adhered to the second sheet panel 22 is pulled apart in the sealed state, the closure segment thereof will begin to tear at the adhered score, thereby revealing the slightest evidence of tampering.

[0095] In such Figure 27 to Figure 29 In yet another specific embodiment shown, the bag assembly 20 includes handle members 32, 36 having spaced apart leg portions 33, 35 and 37, 38 positioned by respective leg channels 87, 88 extending through the first and second panels 21, 22. This enables the distal ends of the respective handle leg portions 33, 35 and 37, 38 to be internally mounted to the inner walls of the respective first and second panels via, for example, mounting strips 90, 91. Fig. 27 and Fig.28 ). Thus, the upper loop portions of the handles 32, 36 are oriented along the exterior of the respective first and second panels 21, 22, while their corresponding leg portions 33, 35 and 37, 38 are aesthetically mounted to the interior of the panels.

[0096] However, in this configuration, since the loop portions of the handles 32, 36 extend outside the first and second panels 21, 22 on both sides of the respective first and second panels 21, 22, the upper transverse portion 39 to be folded over the second edge 27 of the second panel 22 does not need to accommodate the leg portions 33, 35 and 37, 38 of the handles. In other words, the leg portions can just be bent out of the way so as not to interfere with the seal of the single continuous upper transverse portion 39.

[0097] It will be understood that Fig. 27 and Fig.28 This embodiment is best illustrated by pulling tab 56 to resemble Figures 14 to 22 The embodiment of the present invention is positioned below the upper transverse portion 39. Finally, although the leg passages 87, 88 for the passage of the handle leg portions 33, 35 and 37, 38 are shown as a single elongated continuous slit, they can be provided by a plurality of passages, each of which accommodates a corresponding leg portion therethrough.

[0098] Now refer to Fig.30 and Fig.31 , another alternative embodiment is similar to Figure 27 to Figure 29 , but only has a single handle 32. Therefore, the upper transverse portion 39 can be folded over the second edge 27 of the second panel 22 to achieve a sealed state ( Fig.31 ), without interfering with the leg portion of the handle 32. Similar to all previous embodiments, a note tab 58a is included for mounting a note 60 thereon.

[0099] Reference Figure 32 to Figure 38 Another embodiment of the bag assembly is described. According to this embodiment, Fig.32 As shown, there is an upper transverse portion 95 that is adhered to the inner surface of the first upper section 25 of the first sheet panel 21 and extends above the first upper section 25. The adhesion of the upper transverse portion 95 to the first upper section 25 also serves to secure the first handle 32 to the first sheet panel 21. Fig.32 As shown, the first leg portions 33, 35 of the first handle 32 are positioned between the first sheet panel 21 and the upper transverse portion 95. The second handle 36 includes a pair of second leg portions 37, 38 mounted to the inner surface of the second panel 22. The second leg portions 37, 38 can be covered with a patch to prevent inadvertent detachment from the second panel 22. It will be understood that, as shown, the upper transverse portion 95 is narrower than the first panel 21 and the second panel 22, but in other embodiments, the upper transverse portion 95 can be almost as wide as the first panel 21 and the second panel 22.

[0100] At the distal portion of the upper transverse portion 95, a closing adhesive 40 is disposed on its inner surface facing the second panel 22 when in the unsealed state. The upper transverse portion 95 includes a pair of handle cutouts 93, 94 that are neatly aligned with the corresponding leg portions 33, 35 of the first handle 32 and taper laterally outward from near the first upper edge 28 to the distal edge of the upper transverse portion 95. A removable protective strip 45 is provided that covers the adhesive 40 and spans the handle cutouts 93, 94. When the protective strip 45 is removed and the upper panel sections 25, 26 are aligned in the closed state, the upper transverse portion 95, which is essentially divided into three closing sections 97 to 99, can be folded over the second edge 27 of the second panel 22 so that the adhesive 40 contacts the outer surface of the second panel 22, thereby substantially sealing the bag opening in the sealed state ( Figure 35 to Figure 36 ). In this arrangement, the leg portions 33, 35 and 37, 38 of the first handle 32 and the second handle 36 are received by respective handle cutouts 93, 94 of the upper transverse portion 95. Although the handle cutouts 93, 94 are shown as substantially V-shaped cutouts, it will be appreciated that other configurations of the cutouts are possible.

[0101] like Fig.32 and Fig.34As shown, a pre-folding line 92 is provided on the upper transverse portion 95. The pre-folding line 92 is Fig.32 and Fig.34 The upper transverse portion 95 is configured to be folded over the opposite second edge 27 of the second sheet panel 22 along the pre-fold line 92 when the opening into the bag interior of the bag is positioned in the closed state before the opening is sealed in the sealed state. Figure 35 to Figure 36 ).

[0102] To accommodate the lower leg portions 33, 35, 37, 38 of the opposing handles 32, 36 mounted to the corresponding first and second panels 21, 22, the upper transverse portion 95 includes handle cutouts 93, 94 aligned therewith. These aligned handle cutouts 93, 94 divide the upper transverse portion 95 into three independently foldable closure segments 97, 98 and 99, enabling the upper transverse portion 95 to be folded over the corresponding second edge 27 of the second panel 22 regardless of the lower leg portions of the handle member. Thus, once the protective strip 45 is removed, the exposed adhesive 40 on each closure segment 97, 98 and 99 can be adhered to the corresponding outer surface of the second panel upper segment 26, thereby sealing the closed bag in a sealed state ( Figure 35 to Figure 36 ). When the opposing upper sections 25, 26 of the first and second panels 21, 22 are oriented in the closed state, the foldable closure sections 97, 98, 99 each extend sufficiently above the first edge 28 to easily extend and fold over the opposing second edge 27.

[0103] To prevent accidental closure or contact of the closure adhesive 40 on the closure segments 97 to 99, the upper transverse portion 95 includes a manually removable protective strip 45. The protective strip 45 covers the adhesive 40 and horizontally spans the gap created by the handle cutouts 93, 94 of the upper transverse portion 95. In this way, the protective strip 45 can be removed as a single unit, rather than removing three separate units. This significantly reduces the time and effort required to remove the protective strip 45 during the sealing bag assembly.

[0104] In this embodiment, the pre-fold line 92 is disposed along the upper edge of the pull tab 96 just above the pull tab 96 and the upper perforation line. The pull tab 96 is positioned above the upper edge 28 of the first sheet panel 21 to open the bag assembly from a sealed state ( Fig.35 and Fig.36 ). The pull tab 96 may be provided with a grip tab 89 at one end or at both opposing ends. In this embodiment, a plurality of perforations, score marks, cuts, etc. are created along the top and bottom edges of the pull tab 96 to aid in tearing when sufficient force is applied to the pull tab 56 ( Fig.37Preferably, a pair of parallel perforations are provided, the pair of parallel perforations extending generally along the longitudinal axis of the connecting seam pull tab 96. By placing the pull tab 96 ( Fig.38 ) is completely separated from the bag assembly or by merely cutting a row of perforations, the bag assembly can be moved to an open position to access the contents. Of course, it will be appreciated that if tampering with the bag assembly is attempted, any unauthorized breaking or tearing of the perforations will readily reveal any evidence of tampering due to the visual separation of the score or perforations.

[0105] One of the outer closure sections 97, 99 may include a note tab 100 configured to secure a note 60 or the like (eg, a purchase receipt, order slip, or bill of lading) to the bag assembly. Fig.35 and Fig.36 As shown, the corresponding outer closure segment 97 includes a dividing slit that divides the closure segment 97 into two portions, one of which creates a note tab 100. Although either dividing portion of the closure segment 97 may be employed as a note tab, it is preferred to use the innermost dividing portion that is closer to the aligned leg portions 33, 37 and 35, 38 of the handles 32, 36.

[0106] The note tab 100 also includes the same closure adhesive 40 disposed on its inner surface. Initially, when the protective cover 45 is removed from the closure adhesive 40 and the closure segments 97-99 are adhered to the second panel 22 in the sealed state, the note tab 100 will not be adhered to the second panel 22 in the unmounted state. Then, the note 60 can be placed between the corresponding closure adhesive 40 of the note tab 100 and the outer surface of the second panel 22, and the note 100 58a can be urged into adhesive contact with the note 60 in the mounted state. Upon grasping the grip tab 89, removal of the pull tab 96 (essentially along the perforations) and removal of the note tab 100 and the mounted receipt or note 60 is achieved, as shown in FIG. Fig.37 and Fig.38 It will be noted that in the illustrated embodiment, only one note tab 100 is included along one of the outer closure segments 97, 99. However, a note tab 100 may also be provided by the intermediate closure segment 98 if desired.

[0107] A plurality of small vent holes may be provided in the first and second panels 21, 22 and / or in the side gussets. These vent holes 63, shown as circular, may be of nearly any shape or score. Such venting allows steam or the like to escape from the hot food container to prevent the sealed bag assembly from over-expanding or the contained food from becoming too moist.

[0108] Each of the closed segments 97 to 99 of the upper transverse portion 95 includes a tamper-proof V-shaped notch 86 to present the slightest tamper evidence. Preferably, the notch is provided by a plurality of spaced V-shaped scratches 86. However, it will be understood that almost any notch shape can be adopted. For example, the notch can be S-shaped, X-shaped, etc. However, the vertical or substantially vertical notch line of the notch 86 must extend across the following adhesive strip 40 and extend across the lower portion in the sealing position of each closed segment 97-99, where there is no adhesive below (that is, this portion of the closed segment is not adhered to the second sheet panel 22). Therefore, when the lower distal portion of any one of the closed segments 97 to 99 adhered to the second sheet panel 22 is pulled apart in a sealed state, its closed segment will begin to tear at the adhered notch, thereby revealing the slightest tamper evidence.

[0109] In some embodiments, an elongated plastic strip may be arranged and adhered to the back of the pull tab 96. The strength of the plastic strip is much stronger than the strength range of the heavy-duty paper used in most conventional paper bags, thereby allowing the plastic strip to tear through the material of the pull tab 96. Therefore, due to the sturdiness of such a plastic strip, perforations or scores may not be necessary, or may only need to be provided near the grip tab to facilitate the initiation of tearing. In addition, as Fig.38 As shown, the pull tab 96 can be used to remove the unbonded portion of the upper transverse portion 95 from the bag assembly, restoring the bag assembly to a conventional tote bag. Fig.38 As shown, the closure segments 97, 98, 99 remain adhered to the second panel 22, and the pull tab 96 and note tab 100 can be torn away from the bag assembly. Alternatively, the strip need not be formed of plastic, but rather of a stronger material than the material of the upper transverse portion 95 that is designed to tear the material of the upper transverse portion 95, such as heavier paper and fibers formed of nylon, cotton, etc.

[0110] Although the present invention has been described in conjunction with the preferred form of implementing the present invention and its modification scheme, it will be appreciated by those skilled in the art that many other modifications may be made to the present invention within the scope of the following claims. Therefore, it is intended that the scope of the present invention is not limited in any way by the above description, but is determined entirely by reference to the following claims.
