• Products for veterinary use for example those used in farms, are often contained in containers (flasks, vials, bottles, etc.) made of glass. Given the conditions under which they are used, it is not uncommon for vials to escape the operator's hold (the veterinarian or breeder) and inadvertently dropped onto the floor during handling of the product or trips. It happens then that the bottles break. In view of the cost of certain products, this loss has practical consequences (delay in the administration of the drug to the animal) and economic (necessary replacement of the product to treat the animal).
• the existing protections for commercially available pharmaceuticals are plastic boxes that surround the vial containing the drug product. They are expensive and have the disadvantage that it is not possible to visually control the level of product in the bottle, the latter being largely masked by the plastic box.

• the cups are preferably manufactured by thermocompression, for example in a vulcanizing press.
• the present technique relates to a shock protection device adapted to equip a bottle 1, having a cylindrical body 11 of revolution terminated, at a first end, by a bottom 10 and, at a second end opposite to the first end, by a distal portion comprising successively from the body 11, in a longitudinal direction of the bottle 1, a shoulder 12, a neck 15 and a neck 16, said device comprising a first cup 2 configured to cooperate firmly with the bottom 10 of the bottle 1 and a second cup 3 configured to cooperate firmly with the shoulder 12 of the bottle 1, each of the first and second cups 2, 3 having a shock-absorbing portion able to protrude, in a transverse plane 19 which is perpendicular to the longitudinal direction 18, beyond a zone of larger diameter of the bottle 1, characterized in that the protruding portion of the damping portion of at least one of the first 2 and the second cup 3 is made of an elastomer, preferably an elastomeric silicone or a thermoplastic elastomer polyurethane (TPE-U or T
• the aforementioned international application WO2014128179 A1 describes an impact protection device comprising an upper shell and a lower shell each comprising a stiffener in the form of a circular volume which projects from the inner face of the cup to protect the bottle in case of shock. Said stiffener can also be oriented longitudinally with respect to the bottle.
• the cups have shapes that define with the wall of the bottle annular volumes filled with air that participate in the absorption of shocks.
• the cups consist of an injectable resin.
• the polymer used for the manufacture of cups described in this application is low density polyethylene. The hardness of such materials is generally measured on the Shore D scale and is of the order of 60.
• a device according to this variant allows, geometrically equal configuration but consisting of an elastomer, to significantly improve the resistance of a bottle during a fall.
• the device also makes it possible to dispense with a heat-shrinkable sleeve, thus resulting in a saving in material and to avoid subjecting the product contained in the bottle to heat.
• the damping portion may advantageously be a plurality of pads as described above or a full annular volume, empty or hollow.
• the annular volume is empty.
• the annular volume preferably extends over the entire circumference of the bottle and advantageously forms a protuberance of constant thickness, in the form of a torus for example or another form of bead.
• an elastomer having a Shore A hardness of at least 80, advantageously at least 85, more advantageously at least 90 it is possible to use an elastomer having a Shore A hardness of at least 80, advantageously at least 85, more advantageously at least 90, and
• an elastomer having a Shore A hardness ranging from 20 to 95 is advantageously used.
• the Shore A hardness is from 20 to 85, advantageously from 50 to 80. at 85, preferably 75 to 85, for example 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, or 85.
• an elastomer silicone having a Shore hardness is used.
• thermoplastic elastomer polyurethane TPE-U or TPU
• TPU thermoplastic elastomer polyurethane
• the impact energy is absorbed by the deformation of the material.
• a protocol used to test the effectiveness of different protection devices is described below:
• a 250 ml bottle filled with water is equipped with a device consisting of a thermoplastic elastomer polyurethane (TPE-U or TPU) (Shore hardness 85A).
• TPE-U or TPU thermoplastic elastomer polyurethane
• the lower cup covers about 30% of the lower part of the bottle (bottom included) and the upper cup also covers about 30% of the outer surface of the bottle.
• the overall thickness of the projecting portion and the base is 7 mm and the bottle has a diameter of 66 mm.
• the impact resistance is very much improved with a device consisting of an elastomeric material (Shore A hardness 85) instead of a low density polyethylene.
• a device consisting of an elastomeric material (Shore A hardness 85) instead of a low density polyethylene.
• the equivalent material the presence of pads forming a discontinuous damping surface significantly improves the impact resistance with respect to a continuous damping surface. It has been found that the gripping of a bottle equipped with the device is particularly good (better than that of a bottle without a device and better than that of an equipped bottle and two cups each having an empty annular bead).
• the studs distributed on the cups participate actively in the improved ergonomics and the visibility of the water level in the bottle is excellent.
