Description: BACKGROUND OF THE INVENTION The present invention concerns a packaging for metallic findings and others, particularly small blocks and twist drills. It is known that during the use of the drill in a room a boring dust spreads and places on the floor, on the furniture and on the most hidden and inaccessible corners of the room. The technical aim of the present invention is to remedy these defects. A purpose of the present invention is to create a packaging capable of housing the findings and preventing the scattering of the dust in the environment. A second purpose of the present invention is to reach the above aim by means of an easy structure, to be easily manufactured; in addition, the invention assures a safe use and an effective functioning. A further purpose is the total recycling of the packaging, which can be used again for more times to house the dust due to the drilling. EP- A -0 401 520 refers to a collector for dust created when drilling a hole in a wall. The collector consisting of a hollow housing with two opposite aligned apertures. The housing is fitted with an adhesive coated ring surrounding one aperture, so that the housing can be adhered to the wall. A twist drill is then passed trough the two apertures to drill the hole in the wall. The dust generated when drilling is collected inside the housing. The main features of the collector disclosed in this document are essentially as follows: 1. The housing defines a hollow interior of the collector. Therefore, the housing has means for defining two substantially aligned opposite apertures, the housing being provided, on the exterior thereof, adjacent one of said apertures defining means, with means to secure the housing to a wall. 2. The means to secure the housing to a wall comprise adhesive means forming a seal between the wall and the aperture defining means. 3. The adhesive means consist of an annular element presenting two opposed adhesive faces, one adhesive face is secured to the housing and the other is exposed to be mounted on a wall. 4. A line of mechanical weakness defines a circular disc, which can be readily separated from the housing for creating said aperture. 5. An adhesive patch, label or the like covers the aperture. 6. The housing has transparent walls. 7. The housing consists of a backing sheet connected to a removable cover; the cover and the sheet co-operate for defining said housing. 8. The backing sheet presents a slot to enable the backing sheet to be suspended from a support. 9. The device forms a package containing goods or items to be sold. 10.A method is further provided for collecting dust during the drilling of the wall securing the device to a wall with said apertures in alignment with the hole to be drilled, passing a twist drill through the aligned apertures to contact the wall and operating a drill secured to the twist drill to cause the drill to drill the hole, and catching the dust within the housing. US -A -2 993 590 refers to a transparent packaging adapted to show small objects. The packaging consists of a flange bubble with an opening closed by a removable strip of flexible material. The packaging contains findings of every type or other similar products. The packaging, having the aim to show them, presents a transparent wall. US - A - 4 901 858 refers to a blister packaging capable of self-supporting. The packaging consists of a goblet with an external bubble surrounded by an edge. The inclination of the edge with respect to the bubble suggests a way of manufacturing of the blister with plastic sheets and backing sheets. The hollow body, shaped as a box, presents an opening, at least a lateral wall and at least a wall opposite to the opening; when the hollow body is a part of the packaging, that is when it is joined to the plate element, the opening is closed by a portion of said element; the opposite wall presents an area capable of being drilled by a twist drill, the drilling can occur when the hollow body is disjoined from the plate element; the disjoining allowing the use of the hollow body for housing the dust due to the drill, which, otherwise, should be scattered in the environment; the drilled area can facilitate and guide the crossing of the twist drill every time the hollow body is used to hold the dust. When the hollow body of the packaging is separated from the plate element, and it does not contain small blocks or findings, its opening can be supported by a wall to be drilled so that the hollow body can hold the dust due to the drilling. BRIEF DESCRIPTION OF THE DRAWINGS Other advantages, features and aims of the invention, may be more readily understood by referring to the accompanying drawings, which concern preferred embodiments, in which: Fig. 1 shows a perspective projection of the hollow body according to the invention; Fig. 2 illustrates a plan of the separated hollow body and plate element; Fig. 3 is a perspective projection of a second embodiment of the packaging including the hollow body and plate element; Fig. 4 is a perspective projection concerning the hollow body of Fig. 3 ready to be used; Fig. 5 is a perspective projection of the hollow body in a position where a gasket is detached from the hollow body; Fig. 6 is a perspective projection of the packaging closed by the plate element; said packaging housing findings (small blocks) and a tool for holding the dust; Fig. 7 is a perspective projection of the hollow body which is used for holding the dust during the drilling. DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION Referring to the above Figures, a packaging 1 includes a plate element 2 and a hollow body 6; the hollow body 6 is defined by the surface of a body; the perimeter of the basis of the body lies on a plane, said body presenting a central opening 16 which can directly or indirectly rest on the surface of the wall to be drilled; to form the packaging 1, the plate element 2 and the hollow body 6 are joined by known joining members. With reference to Figs 1, 2, the hollow body 6 is shaped like a box with a central opening 16, through that the packaging 1 is filled with said findings before to be closed by the joining members 3, 11; four lateral walls 17, 18, 19, 20 are provided, and one wall 21 is opposite to the central opening 16; the wall 21 closes, together with the lateral walls 17, 18, 19, 20 and a portion 4 of the plate element 2, a space 7. The side portion of the plate element 2 is fitted with a guide 3, consisting of the refolding of a rectangular area of the plate element 2, the guide 3 being delimited by preferential cutting lines 5. The guide 3 joins the plate element 2 to the hollow body 6, while the preferential cutting lines 5 allow an easy removing of the portion 4 closing the central opening 16 when the hollow body 6 and the plate element 2 are joined; on the contrary, when the hollow body 6 and the plate element 2 have been disjoined by removing the material alongside the preferential cutting lines 5, the opening 16 is free and the hollow body 6 can be used to hold the dust. The packaging 1, closed for housing small blocks or twist drills, consists of the plate element 2 and the hollow body 6 joined through joining members 3, 11 so that the portion 4 of the plate element 2 can close the central opening 16; in addition, an area 10 capable of being drilled by a twist drill is provided in a recess of the wall 21 of the hollow body 6; the area 10 is radiused to the wall 21 by concentric circular depressions 8, 9, the radius of which decreases up to reach the dimensions of the area 10; the area 10, when the plate element 2 is joined to the hollow body 6, is closed by the material of the hollow body 6 to maintain the original state of the box; therefore, the recess consists of the depressions 8, 9 and of the area 10. On the contrary, when the plate element 2 is not joined to the hollow body 6, it is possible to drill the area 10 by means of a twist drill so that the twist drill enters into the space 7 contained by the hollow body 6 and, therefore, to the wall to be drilled on which the opening 16 rests. The recess is used as draft for the twist drill. In the embodiment of Fig.2, the joining members include the guide 3 and a side and plane flange 11 which engages the guide 3 with two long sides 11a, 11b and a short side 11c; the sides 11a, 11b, 11c, 11d, are found around the central opening 16. To remove the findings from the packaging, the hollow body 6 is disjoined from the plate element 2. After disjoining, it is possible to use the hollow body 6 to hold the dust due to a drilling; for this purpose, the central opening 16 of the hollow body 6 rests on the wall to be drilled, the drill is inserted in the recess of the area 10 and the drilling can be started; the plane flange 11 of the hollow body 6 being used as sealing gasket. The material closing the area 10 is drilled and removed by the twist drill. In this way, during the drilling, all the dust remains in the space 7, so that all the above mentioned problems and inconveniences can be avoided; in addition, during this operation, the recess 8, 9 and the area 10 guide the twist drill; the recess is used as a draft for the twist drill. This guiding function of the recess 8, 9 is carried out every time the hollow body 6 is used to prevent the dust from being spread in the room. Advantageously, a second embodiment of the packaging is provided (Figs 3, 4, 5), in which the plane flange 11 co-operates with a gasket 14 to increase the sealing effect of the space 7; the gasket 14 is obtained from the material of the plate element 2 by removing a portion 4 of the plate element 2 by a cutting alongside the preferential cutting lines 15, 15'. The annular gasket 14 is found under the plane flange 11 and around the central opening 16, the central opening 16 allowing the access to the inner space 7; the gasket 14 adheres to the plane flange 11, since the body 6 is joined to the plane element 2 through the plane flange 11, when the packaging is brand-new. The joining of the hollow body 6 to the plate element 2 can be obtained by sticking or heat sealing. In addition, the lateral walls 17, 18, 19, 20 are fitted with stiffening ribs 22 which stiffen the hollow body 6 supporting the pushing of the twist drill. The packaging 1 of Fig. 6 contains small blocks 23 and a hollow body 24 capable of holding the dust due to the drilling; the shape of the hollow body 24 is identical to that one of the hollow body 6, except the fact that the hollow body 24 is found inside the packaging 1, instead of being fixed to the plate element 2. Of course the packaging 1 can contain a plurality of hollow bodies 24 with or without small blocks 23. In addition, only a wall 25 laterally delimits the hollow body 24. Fig.7 demonstrates the use of the hollow body 6 (24) to hold the dust due to the twist drill 26 in the space 7. In an embodiment (not shown), the area to be drilled 10 is found in any point of the wall 21 opposite to the central opening 16.
