BRIEF SUMMARY
DESCRIPTION
1. Field of the Invention
The present invention relates to a container for the mailing and transport of objects, particularly suited to be closed with a seal.
2. Description of the Prior Art
Seals are frequently used in cases of mailing and transporting objects of various types, such as packages, boxes, trunks or entire train cars. The seals function not so much to prevent third parties from stealing or manipulating the goods as to allow the recipient to be certain that no one has altered the goods during the trip. In fact, the recipient need only verify that the seal is intact, such seal being even a simple lead sealed string or cord covered with sealing wax as well as any of the more sophisticated means. On the lead, sealing wax or other sealing means, codes, symbols or other signs are imprinted which are in the possession of only the persons responsible for mailing the package and which are difficult to falsify.
Normally, in order to mail packages with seals, it is not necessary for the package to have a specific form, but only that it be tied with a seal applied to the knot. However, when mailing goods of a certain importance, such as occurs frequently in the field of jewellery, there are no suitable containers which can be closed in a rational way with materials normally on hand.
In these cases, in fact, it is frequent to see containers suited to other purposes which are closed with adhesive tape, tied with string and then sealed in correspondence to the knot. In the case of customs inspections, even if the containers are resealed after the check, the closing and sealing are rarely carried out with the same care used by the person who prepared the package for mailing, with the risk of not being able to recognise possible subsequent tampering.
To overcome this inconvenience, types of containers, such as boxes in the form of small trunks, are known which are suited for being closed and sealed in a rational manner. They have a top opening from the edges of which pins protrude which are made to engage in holes formed in a corresponding cover. At the ends of the pins, holes are present which, once the cover is introduced, can be tied by means of seals so that it is impossible to extract the cover from the pins without breaking them. This type of sealable container, however, requires that every time it is closed as many seals as protruding pins (normally 4 to 6) be applied. Therefore, in the case of mailing many containers, the execution of the seals can be rather time consuming. Furthermore, the cover often vibrates with respect to the container since the seals are not able to block it sufficiently.
A particularly practical container is described in EP 0484294 and comprises a flat box having an upper opening closed by a slidably engageable cover. The box on opposite side walls has projections engaging with a plurality resilient appendages provided on two opposite edges of the cover, so that they can clamp on each other. Even if it is designed for containing electronic equipment, and for this reason it comprises an annular rubber element put between the cover and the box, it could be suitable also for being tied and sealed through two aligned holes respectively provided for in the box and in the cover and engaging with a screw. However, many portions of the perimeter of the container offer possible ways for entering the container with thin flexible gripping means, or with sucking means, and steal small gold pieces, small jewels or precious stones without neither cutting the seal or damaging the box.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a container for the mailing and transport of objects which is suited to be closed even with a single seal, which allows for rapid application of the cover without being able to oscillate during transport and which, at the same time, can be easily closed and sealed again after possible inspections, offering no ways through which it can be entered without cutting the seal or damaging the box.
