Background technique

Packaging bags play an important role in the retail industry today. Many packaging bags are designed to serve various aspects of the transaction, such as packaging convenience, attracting consumer attention, reducing waste, extending product shelf life, and more. One of the most important aspects of the transaction is consumer demand and satisfaction, including enabling consumers to move purchased items without the assistance of a shopping cart, or the need to utilize separate plastic bags such as t-shirt bags for re-bags. Bags with carrying handles were developed to meet these needs. the

However, many such bags still suffer from disadvantages and do not satisfy this need satisfactorily. Known prior art includes, for example, a bag with finger holes in the handle. However, handles of this type have proven to be insufficient for prolonged carrying of items, since when required, the handle tends to become lodged in the palm or fingers of the operator causing discomfort. Another common disadvantage with bags of this type is that the handle cannot bear the weight of the product and stretching or tearing of the handle is a frequent occurrence. the

US Patent No. 3,774,837 discloses a carrier bag having two broad sides made of tubular synthetic resin mesh and a folded bottom. At the open end of the bag there is provided a reinforcing fold or strip extending transversely with respect to the bag. The grip opening is perforated in the center of the edge of the opening. Reinforcing folds or strips are welded to the broad sides of the bag by welds running obliquely towards the edge of the opening, one on either side of the grip opening and spanning the entire width of the fold strip. The handling grip is thus formed by the central part of the reinforcing fold or strip between the inclined welds. the

International Patent Application Publication No. WO 2008/056694 discloses a packaging material capable of forming packages each having a carrying handle and capable of being rolled into a roll and subsequently continuously unrolled. The packaging bag material includes an elongated tubular body made of a resin film and including a front panel and a back panel. A strip is arranged between portions of the front and rear panels extending from the first thermally bonded portion towards the second side edge, the longitudinal direction of the strip coincides with the longitudinal direction of the tubular body. The front and rear panels are bonded to the strip sheet at bonding portions having a predetermined length and are longitudinally spaced apart from each other by a predetermined pitch so as to define unbonded portions between adjacent bonding portions, resulting in a large number of mutually connected bags arranged in a row in the longitudinal direction . The portion of the strip at each unbonded portion serves as a carrying handle. the

International Patent Application Publication No. WO 2009/054151 discloses a bag material for constructing a package having a carrying handle portion that allows roll winding and back winding for continuous supply. The tapes for the carrying handles are inserted at constant pitches in the longitudinal midstream of the tubular base material of the base material. The end portions of the tape are fusion bonded to the face and back side panels by providing two heat seal regions. The premium edge side of the bag material is sealed by providing a third heat seal area. The base material at predetermined positions along the opposite side edges of the adhesive tape for the carrying handle is cut away in its longitudinal direction. After the bag is packed with the substance to be packed and the opening is sealed, in the non-sealed area, the tape for the carrying handle is pushed out of the inner space of the sheet, thereby forming the carrying handle portion. the

It is therefore an object of the present invention to provide an alternative arrangement of packaging bags comprising carrying handles with improved load bearing. the

Fig. 4 shows a further embodiment of a bag 15 having a carrying handle in accordance with the principles of the present invention. In this embodiment, the bottom 85 of the package is configured to be expandable. In this embodiment, the sheet material is folded, as shown in FIG. 3 , wherein the sheet material is double folded at an area defined as the bottom of the package 15 , thus forming an expandable bottom 85 . The sheet material can be folded several times to achieve greater expansion of the bottom 85 of the package 15 . However, this is not preferred as bonding of multiple layers of overlapping sheet material may be difficult. the

In a further embodiment, as shown in FIG. 6 , a package 15 with carrying handles can be prepared with a dual handle portion 25 . In this embodiment, the sheet material is folded as shown in FIG. 5 . In this embodiment, the sheet material is double folded at the area identified as the handle portion 25 , with each fold becoming a separate handle portion 25 . The arrangement of the handle portion 25 and the handle bar 70 is the same as previously described. Since the package 15 is made from a continuous single piece of sheet material, the two handle portions 25 share a common bridge section 90 disposed between them. Once the package 15 is filled with the pre-weighed product, the side edge 45 comprising the opening 60, the bridge section 90 and the insert 65 in which the handle strip 70 is secured are sealed. Thus, in this embodiment, a consumer can cut along bridge section 90 to gain access to the contents of package 15 . Therefore, the empty packaging bag 15 can be reused as a carrier bag. the

In a further embodiment, as shown in FIG. 8 , the package 15 includes a dual handle portion 25 and an expandable bottom 85 . The double handle portion 25 and the expandable bottom 85 are formed by the folding method shown in FIG. 7 . The arrangement and configuration of the handle portion 25 and the expandable base 85 are as previously described. The packaging bag 15 according to this particular embodiment is useful for large size packages with higher loads. the

In a further embodiment as shown in FIG. 9 , in order to assist in the bonding of the ply materials, the package 15 further includes The incision at 100. This is because in embodiments where a double fold is used to form the expandable bottom 85 or the dual handle portion 25, it is more difficult to bond multiple layers of sheet material together or a certain surface of a certain type of sheet material is not affected by thermal bonding, so Removing the inner layers of the sheet material (except for the first wall 35 and the second wall) will improve the bonding of the multiple layers of the sheet material. the

In a further embodiment, as shown in FIG. 10 , the package 15 further includes a diagonal seal 105 disposed at each corner of the expandable bottom 85 . This embodiment is particularly useful when full expansion of the expandable base 85 is not desired or tends to be limited. The angled seal 105 will restrain each corner of the expandable bottom 85 behind the cutout 100, so the expandable bottom 85 will not fully expand at that corner.

In this embodiment, the package 15 is further provided with a zipper 95 between the handle portion 25 and the main body portion 20 . More specifically, a zipper 95 is arranged below the bridge section 90 . The zipper 95 is preferably a non-permanently sealed zipper, ie the zipper can be opened or opened as desired. The zipper 95 includes male and female strips (not shown) disposed on respective first and second walls 35 , 40 of the main body portion 20 of the package 15 . The male and female strips are configured to connect to each other and this connection is capable of withstanding the pressure of the contents of the package 15 so that the zipper 95 does not undesirably unzip. To access the contents of the package 15 , a user can cut along the bridge section 90 and then unzip the zipper 95 to access the contents of the package 15 . When the contents of the packaging bag 15 are empty, the packaging bag 15 can be reused for other purposes, wherein the bag can be resealed with the zipper 95 . the

Figure 14 shows an embodiment of the package 15 in the form of a roll. This embodiment is particularly suitable for automatic packaging of products. In this embodiment, each individual bag is joined to form a continuous roll. The second and subsequent packages 15 adjacent to the first package 15 having the opening 60 are initially prepared without the opening 60 present. However, once the first bag 15 is filled with product, the automatic packaging device will cut off the filled bag below the seal B 55, thus creating an opening 60 for the next bag 15, allowing the continuous operation of the packaging to take place. the

Since a certain embodiment of the bag with carrying handle 15 according to the present invention is intended for automatic or industrial scale packaging, it is preferred that the bag 15 is produced from a single piece of material. However, those skilled in the art will recognize that more than one sheet material may be used by modifying the manufacturing apparatus or making changes to the manufacturing process including manual production. Further, while the bag 15 can be wound continuously to facilitate automatic or industrial scale packaging, the bag 15 can also be prepared as individual separate bags 15 for use in small or medium sized businesses where packaging may be done manually . Also, repositioning of the first and second side edges 45, 50, opening 60, and bottom 85 arrangement may be possible, and such repositioning of elements is considered to be within the scope and spirit of the present invention. For example, side edge 45 may be sealed and opening 60 provided at side edge 50 . It is also possible to seal the two side edges 45 and 50 and provide an opening 60 at the bottom of the package 15 as shown in FIG. 15 . However, setting the opening 60 at the bottom 85 is less preferred for embodiments where the bottom 85 is an expandable bottom. Further, it is also possible that the handle bar 70 need not be a strip material. The handle strip 70 can be a rope or rod of material that allows for securing to the handle portion of the package 15, and the mechanism for securing the handle strip 70 can be other than heat sealing or welding. The mechanism can be changed to suit each different construction or handle bar material. the

As is apparent from the above description, the configuration of the bag 15, particularly the arrangement and configuration of the handle portion 25 and handle strip 70 as set forth above, provides higher performance to the bag 15 with carrying handles so that the consumer can comfortably Carry purchased items safely without damaging the carrying handles as set forth above in the object of the invention. the
