<p>This is of the kind which comprises a bottle-like container (1) manufactured from a plastics material and filled at the time of its manufacture with a sterile washing fluid, and a shower device (2). The neck (3) of the container (1) has at its outer end a seal (4) in which the material is thinner than in the rest of the container (1). The shower device (2) is so designed as to exhibit, once the seal has been broken, an outlet orifice (7) for washing fluid communicating with the inside of the container and an eye-cup (6) intended during showering of an eye to centralize the outlet orifice (7) relative to the eye and to hold the eye open. Characteristic of the invention is the fact that the aforementioned showering device (2) is designed to enclose the seal (4) and a part of the neck (3) like a cap (5), and that it is executed with two projections (8, 10) so arranged, when the shower device (2) is displaced from an initial position towards a working position by striking with the hand, for example, against the eye-cup (6), as to penetrate the seal (4) and the container. The projection (8) which penetrates the seal (4) is a pointed tube which provides a communication between the inside of the container (1) and the outlet orifice (7). The second projection (10) is so arranged as to penetrate the container (1) at a point on the neck (3) at which, when the container (1) is inverted, a lower fluid pressure is present than at the outlet orifice (7).</p> |
