Definitions

  • the present invention relates to generally to envelope construction, and more particularly to a mailable container such as an envelope, that may be used for several purposes.
  • envelopes are known generally from the prior art, for example, return mail envelopes, which often comprise a construction of several parts, some of which may be detachable and mailable as the return envelope.
  • US4462538 One example of a multiple function envelope is described in US4462538.
  • This document teaches the use of a mailing envelope for return mail, wherein the envelope is further provided with a detachable carrying handle enabling handheld delivery of the contents held within the envelope, and if necessary or as required, a postal service return of said envelope to the appropriate return addressee, after the handle has been detached.
  • One object of the present invention is therefore a mailable handheld transport bag comprising a first section having a first end, a second section having a second end opposite the first end of said first section, and a third middle section located between the first and second sections, wherein: the first, third and second sections together form the respective side walls of said bag, and define an inner volume adapted in size and dimensions for the insertion and transport of a mailable object; said first section is closed at said first end; said second section comprises an opening located at said second end, the opening being adapted in size and dimensions for the insertion and removal of a mailable object; said first section is closed at said first end by a first flap of material extending from a first side wall of said bag and being folded over, and affixed onto, a second, opposite-facing side wall of said bag adjacent said first end; and said first flap comprises a carrying-handle integrated into said flap.
  • the term“mailable” as used herein refers to the capability, due to the configuration thereof, that the bag according to the invention has in order to transit via a mail, courier or other package delivery system without damage to the multifunction bag, and more particularly, without the bag getting caught in the handling systems that such delivery systems use and potentially damaged.
  • the term“handheld bag” as used herein refers to the notion that the bag must be carryable by hand, either one-handed or two-handed, but preferably one-handed, in the manner of a traditional paper or plastic shopping or grocery bag provided with carrying handles.
  • the mailable bag according to the invention thus has a first section having a first end; a second section having a second end opposite the first end of said first section, and a third middle section located between the first and second sections.
  • section refers to an identifiable functional zone or area of the bag.
  • the first section, second section and third section together therefore form the respective side walls of said bag, and define an inner volume adapted in size and dimensions for the insertion and transport of a mailable object, such as an item of clothing, a book, or any other appropriate product.
  • a mailable object such as an item of clothing, a book, or any other appropriate product.
  • said bag can be described as having a top, a middle, and a bottom.
  • the first section, second section and third section define a bag with at least two substantially planar and opposite-facing side walls, and at least two expandable and opposite- facing side walls, with the expandable side walls being connected respectively to a
  • Each side wall has a corresponding outer face and inner face.
  • the invention relates to a multipurpose bag, in particular a mailable handheld transport bag.
  • this bag is in the shape of, or substantially in the shape of, an envelope.
  • the envelope bag according to the invention comprises two substantially planar and opposite-facing side walls, and two expandable and opposite-facing side walls.
  • the expandable side walls are for example provided by a concertina-like fold provided in the material of the expandable side walls, in a manner known in the art.
  • the expandable side walls could be configured through any other known means, for example, through the use of elastic or stretchable material or the like.
  • the first section is closed at said first end.
  • the top of the bag is therefore closed. This is unlike and contrary to most commonly provided grocery or shopping bags provided with handles, which tend to be open at this point in order for the goods to be inserted or introduced to the bag via an opening in the top.
  • the first section, or top is closed at said first end by a first flap of material extending from a first side wall of said bag.
  • the flap extends from the first end outwards, or upwards, depending on one’s point of view, and then folds over onto a second, and opposite-facing side wall of said bag adjacent said first end, and is affixed at least in part to an outer surface of the second
  • the second section comprises an opening located at the second end, and the opening is adapted in size and dimensions for the insertion and removal of a mailable object. It can be understood from this explanation that the opening of the bag that is used for insertion and removal of any objects into and from the inner volume is not the traditional provided top end opening. On the contrary, that item introduction opening in the bag according to the present invention is located at the second end, or in the alternative description paradigm, at the bottom of the bag.
  • the bag has an integrated carrying-handle, as opposed to a separable or detachable carrying-handle, and this integrated carrying handle is included in the first flap.
  • the integrated carrying-handle of the first flap can be made of a material different to the material constituting the side walls of the bag, it is nevertheless preferred that the carrying- handle integrated into said first flap be formed from a flap material that is the same material as that of the side walls of the bag.

  • Appropriate means for maintaining the substantially planar configuration of the handles are advantageously provided, for example, adhesive tape can be provided around the cutout or along the frangible lines forming the handles, or alternatively, a portion of the handle and/or frangible line area can be shaped to provide an interlocking surface, so that the handle surface interlocks with a part of the envelope surface along the perforation lines, and as a result, the handles remain in substantially flat alignment with the remainder of the outer surface of the envelope. In this way, the bag will not catch or become damaged by the postal or package delivery system transport or sorting installations. From the preceding description, it will be apparent and understood that the at least frangible portion of flap material is not detachable from said flap.
  • the at least one portion of said first flap that is folded over, and affixed either onto said second opposite-facing side wall adjacent the first end, or alternatively and preferably to an inner surface of said first side wall, is affixed thereto by at least one zone of adhesive.
