ABSTRACT:
FIELD OF THE INVENTION
The invention relates to packaging.
BACKGROUND OF THE INVENTION
Current small handyman epoxy packs have the disadvantage that they tend to leak once the seals are broken, thus leaving sticky deposits wherever they are stored between usage. Invariably the exteriors of such packs become contaminated with the leaked contents making handling unpleasant as well as hazardous to sensitive skin and eyes.
In addition consumers often only require a small amount of adhesive to perform the task at hand, inevitably one or both containers of twin packs can become mislaid after use, resulting in the need to purchase a complete now dual package without having enjoyed the use of all the contents of the original packs.
An object of the present invention is to provide a complete one-use package including the applicator and mixing platform as integral parts.
A further object of the invention is to provide packaging that allows the user to completely avoid skin contact with the contents and can easily and cleanly be disposed of after use.
Further objects and advantages of the invention will become apparent from the following description which is given by way of example only.
SUMMARY OF THE INVENTION
According to the invention there is provided a handyman package for single or two part contents including:
a backing card formed with a plurality of holes;
a membrane fixed to the backing card so as to cover and seal said holes;
a cover sheet laminated to said membrane and backing card and including a corresponding number of blisters as there are holes formed in the backing card, such that when the cover shoot is laminated over the membrane and backing card each blister is positioned over a sealed hole in the backing card.
Preferably the package has three blisters, corresponding to three holes in the backing card, such that a first blister contains a first contents, a second blister contains a second contents and a third blister contains a applicator.
Preferably the first contents may be a first part of a two part reactive adhesive and the second contents may be a second part of a two part reactive adhesive.
Preferably the backing card is provided with a first and a second fold line such that the two fold lines on opposite surfaces which divide the backing card into three sections that can be folded in a zigzag Z shape.
Preferably the first and second blisters are oval in shape and are located on the middle section of the backing card along with their corresponding holes.
Preferably the third blister is elongated in shape and is positioned substantially in the third section of the backing card, but partly positioned across the second fold line dividing the second and third sections and with its corresponding hole also partially across said fold line such that when the third section of the backing card is folded forward through 90° the applicator is caused to erupt through the membrane covering said hole and can be withdrawn from the third blister. The applicator is used to rupture the membrane sealing the holes corresponding to the first and second blisters.
Preferably when the third section of the backing card is folded through 180° it will crush the first and second blisters, discharging the contents of the blisters through their corresponding holes and onto the back of the backing card. The back of the backing card can now be used as a platform for mixing and/or distribution of the first and second contents.
Preferably an additional hole is punched through the packaging in the first section of the backing card. This hole may be used to suspend the packaging from a display stand.
Once the contents have been used for the task at hand, the first section of the backing card is folded backward 180° along the first fold line so as to meet the second section and enclose the surface of the platform and any unused contents thereon. Preferably the applicator is inserted through the additional hole in the first section, the hole corresponding to the third blister and into the third blister such that it holds the folded packaging flat in a zigzag orientation, thus making it cleanly and easily disposed of.
Thus according to the invention, there is provided a package which includes a first and a second contents, a applicator, a platform, a means of transferring both of the contents to the platform, and a means for easily and cleanly preparing the packaging for disposal after use.
Further aspects of the invention will become apparent from the following description, which is given by way of example only.
While the present example relates specifically to two part reactive adhesives, in particular epoxy resin, the principles involved readily lend themselves to other products requiring one-use disposable packaging such as single pot adhesives, point tinters, poison baits, dental impression, filling materials, shampoo and conditioner, fuel and lubricant additives/products and many more.
