DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
Besides the stiff containers and the ones used in industry for automatic packaging, containers can be divided into two main categories:
The present invention relates to the second category.
It aims to remedy a well-known defect coming from the fact that a container which is not completely closed is often unstable, forcing the user to do backward and hazardous handling as he should hold into volume at least one part of the container and fill the objects to be packed at the same time.
The user would thus need three hands: two to hold the container and one to handle the objects. To avoid that, accessories external to the container itself have to be used such as: staples, adhesive tape, glue etc., everything only professional users commonly have at their disposal, they who also have the use of a place adapted to packaging tasks as well as all the required accessories and equipment.
This is obviously not the case of casual users who have to more or less improvise the actual packaging steps, besides the assembling of a container delivered down flat.
Of course, it is sometimes possible to maintain the container with one hand and to fill the objects with the other hand. But this "more or less" is very inadequate for a container designed to be presented to users for any possible packaging cases whereas it is industrially manufactured in series.
But it is exactly what happens nowadays.
The folding containers sold in post offices can be given as examples. They are delivered down flat to the user who has to set sides or sections (which is equivalent) upright, maintain them and at the same time fill the objects to be packed as the container only becomes stable once it is definitively closed.
It can be understood that if the user proceeds in the post-office itself, he does not have the use of any convenience.
If he proceeds at home, he can use a clear table, adhesive tape, string or staples but all this proves the container is not convenient as it is not self-sufficient.
This invention mainly remedies that drawback by providing users, private individuals or professionals, with a container including all that is necessary to its practical use, which makes any accessory useless so that it is stable and steady before the user has to fill the objects to be packed.
This invention will become apparent from the following detailed description of the preferred embodiment when read in light of the accompanying drawings. Of course, the description and drawings are given as reference and non restrictive information only.
