The present invention relates to transportation containers and luggage and more particularly it relates to a method and apparatus to prevent items from shifting or getting broken in the container or luggage while moving or during travel.
People traveling a lot are very familiar with the fact that even if they have suitcases of various shapes and sizes there is often empty space left in the suitcase. Even if the suitcases usually have means to stabilize the packed items, often the items still move in the suitcase during the travel. This again leads to a situation that the garments for example get wrinkled during the travel and thus are not readily to be used when unpacking. Moreover, fragile items may get broken during the travel. Similar problems may be encountered when sending items in a box, container or similar structure by any transportation means. It is a well known practice to wrap fragile items into multiple sheets of paper or bubble plastic to prevent the items from shifting and breaking in the box while moving the box.
Attempts have been made to improve the attachment of the items in the suitcases. In addition to various kinds of clips and strings in the suitcase there are also applications involving inflatable inserts that are to protect the packed items during travel. For example U.S. Pat. No. 6,065,870 discloses an inflatable bladder that is to be inserted into the suitcase to protect the items.
There are not many improvements available for protecting items in moving boxes. U.S. Pat. No. 4,597,244 provides a method for forming inflated wrapping bags, but this method is designed for manufactures or other industrial entities only as it requires heat sealing equipment.
The drawback in the approaches currently known is that the inflatable bladder is to be inflated before the suitcase or the box is closed. This means that the bladder may after all not fill the empty spaces in the suitcase or box but merely give a cushion effect, thereby protecting the items from breaking during movements but not protecting them from moving.
Accordingly, there is a need for a method and an apparatus that would protect the packed items from moving and from breaking. The current disclosure provides a method and an apparatus to protect the items in the suitcase or a box but also to fix them in the original position by preventing them from moving during travel. The current disclosure also provides a method and an apparatus to fill the empty places in a suitcase, box or other structure fully with air.
The instant invention provides a solution to the problems encountered by the currently known approaches. The purpose of the current invention is to provide an apparatus to protect the items in the suitcase or a box but also to fix them in the original position by preventing them from moving during travel.
According to one embodiment of the current invention the compartment divider of a regular suitcase is made of plastic instead of plain cardboard or other regularly used material. According to this embodiment the compartment divider is an inflatable bladder like divider and it fixes the items in the suitcase in fixed positions and fills the empty space in between the items.
According to another embodiment the compartment divider comprises two cardboards, or one cardboard and one wall of the suitcase, and an inflatable plastic bladder attached in between of the rigid cardboards or the suitcase wall and the cardboard. According to this embodiment the divider is a rigid element and the inflatable element is between the cardboards.
The suitcase is packed as usually and the compartment divider regardless of whether is comprises only the bladder or additionally the cardboards is laid down on top of the packed items as usually. The other half of the suitcase is packed as usually and the suitcase is closed. The compartment divider is inflated after the suitcase is closed through a valve that is outside of the suitcase. The compartment divider may be inflated by using a hand held pump or any manual or automatic system (compress air cartridge).
According to another embodiment the compartment divider or an inner wall of the suitcase comprises extendable material that can react for example to change of temperature or air pressure. When the suitcase is, for example, in the luggage compartment of an airplane where both temperature and air pressure decrease the extendable material would inflate and thereby protect the items inside the suitcase.
According to yet another embodiment the inflatable bladder is used in a box to prevent items shifting in the box while moving.
Yet another embodiment is a box or suitcase where the inner side of the box or the suitcase is covered with an inflatable bladder which when inflated can protect the items from each side of the box or suitcase.
Still another embodiment of this invention provides inflatable bags where fragile items may be packed individually in a suitcase or in a box or any other container to prevent them getting broken. The bag may be made of one layer and the air is to be inflated into the bag, or the bag may be made out of two layers and the air is inflated in between of the two layers.
With reference now to the drawings, an improved suitcase embodying the present invention is described.
The improved suitcase according to the present invention includes a suitcase (1) or a box (16) with a compartment divider (2). The compartment divider is a fixed portion of the suitcase or box being attached to a bottom (3), top (4) or side (5) wall of the suitcase or to any wall of the box. The compartment divider may be made of two cardboards (10) and include an inflatable bladder like element (14) in between of the cardboards. The compartment can also be made by one cardboard and the largest wall of the suitcase as fixed element with an inflatable bladder like element (14) in between of the suitcase wall and the cardboard. Alternatively the divider is a bladder and it made out of plastic or any other material that can form such a bladder. The compartment divider is inflatable and deflatable through a valve (6) that locates outside the suitcase or the box, or inserted in any wall or element of the suitcase or the box, thereby enabling inflating and deflating the compartment divider when the suitcase or the box is closed. This allows the user to fill the compartment divider to the exact amount that is needed in order to fill in all the empty places in the suitcase or the box.
According to a preferred embodiment the pump is integrated in the structure of the suitcase: at the bottom between the wheels or in the handle.
The person inflating the bladder shall feel the increased resistance when no more air goes into the divider. At this point the bladder like divider fills all the empty spaces in the suitcase and the items (13) packed cannot move from their original places.
The valve may locate on any of the outside walls of the suitcase or the box. According to a preferred embodiment the valve locates outside of the wall into which the compartment divider is attached, thereby leading to the divider bladder through the side of the divider that is attached to the respective wall of the suitcase.
Usually the compartment divider is attached to one of the side walls (5) of the suitcase and in such suitcase the valve is preferably outside or inserted in this side wall.
According to one embodiment the valve system is locating in the handle (7) of the suitcase. According to another embodiment the valve system may be automated and the bladder like divider may be inflated by regulating an adjuster in the handle of the suitcase.
According to the embodiment where the bladder like element (14) locates in between of two cardboards (10) the bladder may be emptied by opening the valve (6) and attaching the two cardboards together with a rubber bind, a clip or other suitable element to press the cardboards together.
According to the embodiment where the divider does not contain the cardboards, the bladder may be emptied by opening the valve and manually pressing the air out of the bladder.
According to still another embodiment of the invention is a box, or any type of container, used for example for mailing items, where the box contains a divider comprising a bladder like element. The divider may be attached to any of the side walls of the box or it may be attached to the cover portion of the box.
A person skilled in the art will understand that invention according to this disclosure may be conducted with various changes without dividing from the idea of this invention.
