Embodiment approach

[0033] now refer to figure 2 A first embodiment of the invention is described, which is also shown in figure 1 . as it should figure 2 As shown, the bottom 22 is provided with at least two through holes 221, and the through holes pass through the wall thickness of the bottom. These through holes 221 are oriented axially, parallel to the sliding direction of the detachable mechanism 3 . For example, a cylindrical through hole 221 may be configured such as Figure 5 shown, or configure a curved elliptical pass-through hole, such as Figure 6shown. In both embodiments, the through hole 221 extends around the pipe frame 25 and the pipe 23 . These holes 221 establish a direct communication between the interior of the bucket cup 21 and the interior of the container 1 , without passing through the dip tube 24 . The outer wall of the bottom 22 surrounding the passage hole 221 forms a valve seat 222 .

Abstract

The device has: a basic part (2), which is mounted on the container (1), has a dip tube (24) and a bucket cup (21) in which an injection hole (261) connected to the dip tube (24) is formed; and Detachable mechanism (3), which is detachably mounted on the base part (2), has a tube (33) and an applicator (35), adapted to produce a seal by sliding the tube (33) against the piston Suction, keeping the dose of fluid product from the injection hole, the applicator has an extraction application space (35) formed in the tube (33), characterized in that the bucket cup (21) has a discharge valve (221,222,5), The discharge valve makes the inside of the bucket cup (21) communicate with the container (1), so that when the detachable mechanism (3) is installed on the basic part (2) again, the fluid product contained in the bucket cup (21) will flow into the container Pressure delivery.

Description

technical field [0001] The invention relates to a device having a base part and a detachable mechanism detachably mounted on the base part. The detachable mechanism slides sealingly axially over a certain axial travel in the base part. Advantageous fields of application of the present invention are the fields of cosmetics, cosmetics or medicine. The base unit is attachable to the fluid container and the detachable mechanism supports the applicator. Background technique [0002] In the field of cosmetics, it is known that WO2013 / 017803 proposes an applicator dispenser with a detachable mechanism equipped with an applicator, which is adapted to be axially withdrawn from a basic part in a sealed sliding manner, basically The part has a bucket cup with a fill hole in the bottom, which is connected to a dip tube. More precisely, the detachable mechanism is unscrewed from the base part, allowing an axial sliding movement: after unscrewing, the detachable mechanism can be fully ...
