Sprayer, in particular for medical use

摘要

A sprayer includes a container of product to be sprayed, provided with a delivery opening for this product, and a spraying assembly. The spraying assembly is in fluid communication with the delivery opening and is securable onto the container by insertion about a mounting axis. The spraying assembly includes a sprayer body delimiting a proximal area conformed so as to be securable to the container, and includes a distal wall, transverse to the mounting axis, in which a spraying aperture is arranged, and a cap intended to be mounted on the sprayer body. The cap includes a wall transverse to the mounting axis, which is sufficiently rigid so as to bear, without substantial damaging, a force from 50 to 100 N necessary to secure the sprayer body to the container and thus to enable the transmission to the sprayer body of this force.

1. A sprayer including a container of product to be sprayed, provided with a delivery opening for the product to be sprayed, and a spraying assembly, the spraying assembly being in fluid communication with the delivery opening and being securable onto the container by insertion about a mounting axis, the spraying assembly including a sprayer body delimiting a proximal area conformed to be securable to the container, and including a distal wall, transverse to the mounting axis, in which a spraying aperture is arranged, and a cap including an edge locked on the sprayer body behind a planar surface wherein the planar surface extends perpendicular to a longitudinal axis of the sprayer body,
wherein the cap includes a wall transverse to the mounting axis, the wall being sufficiently rigid so as to bear, without substantial damaging, a force from 50 to 100 N necessary to secure the sprayer body to the container and thus to enable the transmission to the sprayer body of the force, wherein the sprayer body and the cap form complementary engaging surfaces, wherein when the complementary engaging surfaces are engaged in an assembly position, axial movement of the cap with respect to the sprayer body is limited, and wherein the cap consists of at least two coaxial parts connected by at least one breakable bridge, wherein one part of said at least two coaxial parts is proximal and is securable to the sprayer body and a second part of said at least two coaxial parts is distal and is displaceable at the moment of use of the sprayer, by rupture of the at least one bridge.
