The present invention relates to a box shipper with an internal inflatable bag.
BACKGROUND OF THE INVENTIONConsumers frequently purchase goods from mail order or internet retailers. Many of these packages include small items such as pharmaceuticals, books, medical supplies, electronic parts, and the like. These items are normally packaged in small containers such as a box or envelope. To protect the items during shipment, they are typically packaged with some form of protective dunnage that may be wrapped around the item or stuffed into the container to prevent movement of the item and to protect against shock. One common packaging method uses corrugated boxes to hold the items to be shipped. The void spaces between the items and the inside walls of the box are filled with void-filling dunnage such as foam “peanuts,” air cellular cushioning materials, crumpled or shredded paper, and other air filled packaging materials. Typically, the corrugated boxes are supplied to the shipper in a collapsed condition so that the boxes occupy less space. Each box must then be erected and taped before use by the shipper which may result in additional labor costs for shipping. The shipper typically maintains a supply of collapsed boxes for subsequent use.

BRIEF DESCRIPTION OF THE DRAWINGSA detailed description of embodiments of the invention follows, with reference to the attached drawings, wherein:
“Inflatable bag” herein refers to a bag, pouch, or similar product, including one made from a single tubular web or two webs that have been sealed together, the bag capable of being inflated by mechanical means. In one embodiment, the bag can be made by a C-fold arrangement, in which a single web of material is folded on itself to create a folded bottom (second end), and the two sides and top (first end) of the thus folded bag are sealed together at or near their respective edges. Typically, an inflatable bag will include a valve or other suitable means to inflate the bag when desired.
“Flat blank” herein refers to a flat piece of material die cut or otherwise prepared such that it can be constructed into a container such as a conventional shipping box. The flat blank can have any suitable size, geometry, and composition, with suitable score lines and cuts as needed to facilitate subsequent construction into a container. The flat blank can be made from any suitable material, including paperboard, polymeric foam, corrugated board, rigid plastic, etc. The flat blank can be monolayer or multilayer in composition, and can be made from more than one of the above-stated materials.
“Heat seal” herein refers to conventional impulse or constant heat sealing techniques, as well as alternative bonding processes, including without limitation RF (radio frequency) or ultrasonic sealing. Both continuous and discontinuous seals are included herein.
“Polymer” and the like herein refers to homopolymer, copolymer, terpolymer, etc.
DETAILED DESCRIPTION OF THE INVENTION
The conventional bag is typically made with a monolayer, polyethylene construction. The bag can alternatively be made with a multilayer construction, and can optionally include one or more layers comprising a polymer that provides an oxygen barrier, such as polyamide. In multilayer embodiments of the bag, the material can be produced by known coextrusion processes, or alternatively by any other suitable process, including known lamination techniques.
Bag 70 includes a first wall 72 and a second wall 74 (see also
In the embodiment of
Another alternative is to apply a non-sealable print surface to the facing surfaces of wall 72 in the region of the bag where the heat seals 112 and 114 are to be located. Upon application of a seal bar or the like to the bag, the two walls of the first panel 73 are sealed together, and the two walls of the second panel 75 are sealed together. However, because of the presence of the non-sealable print surface on the relevant portions of walls 72, the first and second panel 73 and 75 will not seal to each other. The glue, tape, or non-sealable print would require the application of the bonding medium to appropriate portions of the bag material at the time the bag is produced.
Likewise, discontinuous heat seal 130 is like seal 98, but is shown as a series of localized heat seals, of any suitable shape, number and dimension, extending from the second side of the inflatable bag, and extending toward but spaced from the first side of the folded inflatable bag defined by fold 92.
Discontinuous heat seal 128 is like seal 101 of
In one variation of this embodiment, one localized heat seal can be disposed in each of four locations on the bag, such that the four localized seals together define the corners of a rectangle or square. For example, in the drawing of
In
When the bag is to be used to ship an article such as pharmaceuticals, books, medical supplies, electronic parts, and the like, the article is placed in the interior of the bag, and the release tape 124 is peeled from the closure flap 120. This action exposes the adhesive 123. The closure flap 120, with the adhesive layer thus exposed, is then folded towards the first wall 72 of the bag, and the closure flap 120 is then pressed against the first wall 72 to close the bag.
A feature of the inflated bag is that the seals 96 and 98 result, when the bag is inflated, in inflated terminal portions of the bag. These terminal portions, the result of the inflation of regions 102 and 104 of the bag 95 of
In one embodiment, bag 142 can optionally include a double sided tape 148 adhering relevant portions of interior facing walls 72 of bag 142, such that an article that is inserted through opening 145 will be guided by the inverted U-shape configuration of the double sided tape, and thus be beneficially located generally in the central area of the bag.
Centralized location of the article will generally maximize the cushioning protection afforded the article by the invention.
In an alternative embodiment, the double sided tape can be configured as a U shape (as viewed in
The inflatable bag can be used in a number of alternative ways in connection with a flat blank. In one method, the bag of the invention, e.g. the bag of
An article to be packaged can then be inserted into the mouth of the bag. Thereafter the bag can be inflated, and the box then closed. Alternatively, the box can be closed or nearly closed, and the bag then inflated. In one embodiment, a slot 37 can be included in the flat blank that can accommodate the valve 82. The box can be closed, with the valve 82 fed through the slot to provide access to the valve from outside the box, and the bag then inflated. Thereafter, if desired, the valve can be fed back through the slot, and if desired the slot can be covered.
Alternatively, an article can be inserted into an uninflated bag of the invention. Thereafter, at the same location or a separate location, the bag can be inflated, and the inflated bag with the article disposed therein can be placed in a shipper box or other suitable container, and the box or container closed.
Those skilled in the art will understand that modifications in the invention can be made without departing from the scope of the invention as claimed in the claims that follow. For example, in addition to the heat seals disclosed herein, the panels of the bag can be pre-printed with a graphic that visually guides the user in placing an article in the uninflated bag.
