The wrapper which surrounds the product is formed from two pieces, for example, of thin aluminium foil. The first piece is shaped to a generally cup-shaped configuration so as to house the product substantially completely also leaving a projecting edge in the region of the mouth portion of the cup-shaped configuration. The second piece, which retains a substantially flat configuration, is applied and welded to the projecting edge. The rim formed as a result of the connection of the two pieces is then subjected to a shaping operation against the product, conferring on the rim a generally case-like configuration. A case-like housing body with a flat base wall which can support the product is thus formed, the case-like housing body being constituted by an integral part of the wrapper.

A cladding anchor comprising first and second rigid elongate elements being separably connected into a single rigid elongate member, fabric sleeves each having an inner end and an outer end, said sleeves loosely enveloping said elements and remaining separated at the single rigid elongate members, said inner ends of said sleeves being positioned adjacent and separated apart at a central portion of the rigid elongate member, and means for admitting grott under pressure into those sleeves at their inner ends, wherein the sleeves are axially confined between radial abutments fixed at the inner and outer ends of said sleeves and the means for admitting the grout comprises ducts of flexible tube leading through washer-shaped discs which form the radial abutments at the inner ends of the sleeves. 7. A cladding anchor as claimed in claim 6, wherein one of said first and second rigid elongate elements is a tube into which the other of said other rigid elongate elements is a screw. 8. A cladding anchor as claimed in claim 6, and further comprising means for determining when each sleeve is filled with grout. 9. A cladding anchor as claimed in claim 8, wherein the determining means is a duct from said adjacent inner end of the sleeve which serves as a vent for grout. 10. A method of attaching cladding to a building, the cladding having a front side to remain exposed and a reverse side to confront a wall of the building, the method comprising: (a) drilling into the wall of the building to provide at least one drilling in said wall, (b) inserting a first rigid elongate element of an anchor as claimed in claim 6 into each drilling, (c) injecting grout into the fabric sleeves on said first elements to expand the sleeves against the drillings in said walls and allowing the grout to set, leaving the inner ends of said first elements projecting outwardly from the wall, (d) providing blind cavities in the reverse side of the cladding which will register with a respective drilling in the wall, (e) connecting a second rigid elongate element to each of said first elements to form single rigid elongate members, (f) offering-up the cladding so that said second elements of the anchors enter the blind cavities, and (g) injecting grout into the fabric sleeves of said second elements via ducts leading between the cladding and the wall to expand the sleeves against the walls of the blind cavities, and allowing the grout to set. 11. A method of attaching cladding to a building, the cladding having a front side to remain exposed and a reverse side to confront a wall of the building, the method comprising: (a) providing blind cavities in the reverse side of the cladding, (b) inserting a first rigid elongate element of an anchor as claimed in claim 6 into each cavity, (c) injecting grout into the fabric the sleeves on the first elements to expand the sleeves against the walls of the blind cavities and allowing the grout to set, leaving the inner ends of said first elements projecting outwardly from the cavities, (d) drillings into the wall of the building to provide drillings at points which will register with the blind cavities in the cladding, (e) connecting a second rigid elongate element of the anchor to said first rigid element to form a single rigid elongate member, (f) offering-up the cladding so that said second elements of the anchors enter the respective drillings, and (g) injecting grout into the fabric sleeves of said second elements via ducts leading between the cladding and the wall, to expand the sleeves against the drilling walls, and allowing the grout to set. 12. A cladding anchor comprising a rigid elongate member having first and second ends, a fabric sleeve having inner and outer ends, said sleeve loosely enveloping an entire length of said elongate member, means for admitting grout under pressure i nto the sleeve at a zone intermediate the ends of said fabric sleeve, there being at the intermediate zone where the grout is admitted, and means to maintain a rod of the elongate member co-axial with the sleeve, wherein said maintaining means is an annulus having two opposed ends being fitted co-axially on the elongate member at the intermediate zone, said sleeve is separated into two portions by the annulus at the intermediate zone, and said annulus is formed with the means for admitting grout into two said portions of said sleeve on either ends of the annulus, and the sleeve is axially confined between radial abutments fitted at each oppose ends of said sleeve. 13. A cladding anchor as claimed in claim 12, wherein a vent is provided at a further point in the intermediate zone between the ends of said sleeve. 14. A method of attaching cladding to a building, the cladding having a front side to remain exposed and a reverse side to confront a wall of the building, the method comprising: (a) drilling into the wall of the building to provide at least one drilling in said wall, (b) inserting one end of a rigid elongate member of an anchor as claimed in claim 13 into each drilling, (c) providing blind cavities in the reverse side of the cladding which will register with each drilling in the wall, (d) offering-up the cladding so that the other ends of the anchors enter the blind cavities, and (e) injecting grout into the fabric sleeves via ducts leading through the maintaining means of the anchor disposed at the center portion of the rigid elongate member between the cladding and the wall, to expand the sleeves against the drilling and the walls of the blind cavities, and allowing the grout to set. 15. A method of attaching cladding to a building, the cladding having a front side to remain exposed and a reverse side to confront a wall of the building, the method comprising: (a) providing blind cavities in the reverse side of the cladding which will register with the drillings in the wall, (b) inserting one end of a rigid elongate member of an anchor as claimed in claim 13, into each blind cavity, (c) drilling into the wall of the building to provide at least one drilling in said wall, (d) offering-up the cladding so that the other ends of the anchors enter into each drilling, and (e) injecting grout into the fabric sleeves via ducts leading through a maintaining means of the anchor disposed at the center portion of the rigid elongate member between the cladding and the wall, to expand the sleeves against the drilling and the walls of the blind cavities, and allowing the grout to set.
