RECIPIENT WITH A DISCHARGE NIPPLE OF MILLIMETRIC DIAMETERS, FITTED WITH A BREATHER, IN WHICH NO VACUUM IS FORMED AT THE BEGINNING OF OR DURING DISCHARGE OR SUCTION AND AIR DOES NOT PASS THROUGH THE LIQUID, RESULTING IN A UNIFORM FLOW WITH NO SPURTS, AND A TWO-PART RECIPIENT

摘要

The present invention is based on having air at the bottom of the package before discharging or suction (in the case of baby bottles) of the liquid in order to prevent the formation of a vacuum at the beginning of and during discharge or suction, in which said packages have a discharge or suction nipple of millimetric diameters. The first structural variant uses the principle of communicating vessels, with the lower opening (6) of the breather pipe oriented into the recipient. In one variant, the opening of the breather is closed by a stopper and hydropneumatic equilibrium is achieved. The second variant involves a structure in which the inlet of the nozzle of the body of the baby bottle (6) is parabolic and the vertical diameter is much greater than the horizontal diameter, which is equal to the diameter of the breather (5). The third solution involves damming the air above the transverse plate (P) using the liquid when the baby bottle is tipped, forcing the air to be discharged into the atmosphere via the small tube (5a). Other structures achieve the objective of the present invention using mechanical check valves or capillary holes separating the liquid from the air and using surface tension.
