摘要:
Disclosed is a diving mask (1), wherein the mask body (2) shows, in cross section, a substantially truncated-conic shape with diverging walls starting from the glass (3) area towards the face-supporting edge and without undercuts. This allows, to considerably approach the lenses (3) to the face so as to guarantee a wide visual angle. Moreover the inner air volume is decreased with consequent less problems caused by the water pressure, when diving at a certain depth. The walls show preferably two pieces having a different thickness, with a first piece near the glasses (3), having a greater and substantially uniform thickness which supports the face and which connects to a second piece, which is thinner and has a thickness decreasing up to the extreme edge, to guarantee watertightness, without the need to resort to edges, tongues or complex embodiments which would involve the need to resort to complex moulds. This purpose is reached by a diving mask (1), wherein the flat glasses (3) are positioned sloping with the outer edges placed backwards. By choosing in an appropriate way the glass (3) angular position it is possible to obtain a view wherein the objects appear with the real sizes and therefore to have a correct perception of their distance.

摘要:
This invention relates to a flexible mould made of silicone for confectionery, bread-making or similar, particularly suited to the use both in traditional ovens and microwave ovens, consisting of a tray provided, on the upper side, with an edge which estends outwardly, wherein this edge is equipped with a support and stiffening element, preferably consisting of a metallic wire dippen in the silicone or of platic or metallic frame partially co-stamped at sight, or manually inserted into a corresponding seat provided in the edge. This feature considerably improves the handling of the tray, especially when it contains very liquid products, keeping unchanged those flexibility features that make easier to take fragile contents out of the oven and to deform and flatten it in order to store it into a reduced space. Preferrend embodiment of the invention provides for a reinforcing element consisting of a frame (10) (fig. 4) made of rigid or semi-rigid plastic material, which is inserted into a corresponding seat (11) made in the flexible edge (12) of the mould. Preferably the frame (10) is inserted into a seat provided at the lower surface of the edge. The outer part (12) of the edge overlaps at least part-of the frame (10), which is so held in place.

This invention concerns a mould for the injection of polymers, silicones or thermosetting material, consisting of:
a body inserted into a mould seat accessible from the zone where there is the injection hollow and is provided with a feeding duct for the material to be injected and, in the inner part, with an annular element (14) perimetrically outwardly projecting; a jacket (15) which is inserted on this body (11) and shows at its base a threading (16) for the connection to one of the plates which form the mould, said jacket showing at its front end, an inwardly bent edge (17) which defines a undercut apt to engage said perimetrical ridge projecting outwardly from the body (11) to block in position said body (11); a head (18) apt to be inserted on said jacket with an injection nozzle which is placed in correspondence with the material feeding channel (12). It is thereby obtained an injection unit consisting of fewer parts, simply to be carried out and above all which does not require to be fully disassembled when it is necessary to make cleaning and maintenance operations.

This invention proposes a flexible mould for confectionery and breadmaking completely made of silicone, wherein near one or more walls, at least one silicone coating charged with ferrite finely, pulverised is provided. The introduction of the ferrite into the mould causes, in the microwave oven, a release of heat which locally raises the temperature in such a way as to give a "browning" effect to the product. In addition, the mould results to be sufficiently resistant even if made with relatively thin walls and offers a considerable flexibility which allows to deform the mould to extract the product without breaking it and to bend the mould to store it into a reduced space. A support element applied to said edge is provided in order to give the mould a certain resistance, such as to avoid any deformation under the strain of the content. Preferably the support is dipped into the silicone near the peripheral portion of the edge and it consists of a metallic threadlike element. Alternatively the support may be formed by a plastic frame co-stamped with the tray.
