Description

The main patent 25 13 341 relates to a dispensing closure for liquid containers, in particular for bottles. Cans and the like, consisting of a cap made of resilient plastic, the outer side wall or concentric nozzle-shaped inner wall with an internal thread osier a radially protruding, when the cap _hl) bounces onto the container neck with this locking ring projection is provided with a recess the outer side of the cap to accommodate an axially drilled one on the two opposite side walls of the recess with pins _(l -, mounted rocker arm and one in the bottom of the recess formed by the opening by turning the rocker arm by 90 ° into the recess through its thickened bearing end closable opening, wherein the rocker arm is flush with the cap surface in the closed position, with

a) the recess for receiving the rocker arm formed in the outer Rirjiwand of the cap and through the about jjaiiiiiel to the upright Cap axis extending bottom bounded by the cap ringraiim and the end wall is,

b) on the horizontal inner wall of the cap im In the middle area arranged outflow opening through a bore running parallel to the end wall is in communication with an opening in the base of an annular lip and

c) the opening through the thickened ic bearing end of the rocker arm in its with the free end downward swivel hinge is closed and open in the horizontal swivel position.

The invention consists in a development of the main patent, it is based on the object Dispensing closure so that it can be used to spray the liquid contents of a container with flexible wall can be used and its area of use is significantly expanded. So that Use of the propellant gases recognized as harmful are at least largely restricted.

According to the invention this object is achieved in that the dispensing closure according to the main patent to its use as the end of a spray bottle with a flexible wall that passes through the rocker arm Axial bore at the outlet end merges into a spray nozzle via a conical constriction and that at the Inner wall dec cap in the area of the outflow opening in an extension of the same the upper end of one to is attached to the bottom of the spray bottle descending riser.

The dispensing closure is further advantageous, as in the main patent, designed so that the downward Directional rocker arms flush with the outer surface of the annular wall of the Kapp? ^ only and further - how also dimensioned in the main patent so that the free end of the rocker arm after severing its tip still protrudes a little over the lower edge of the ring wall of the cap ready for detection

Regarding the state of the art, reference is made to CH-PS 3 79 421, which describes a spray container with flexible Has wall, so in which the pressure on the liquid to be sprayed by alternating closing and open the hand clasping it is generated. The dispensing closure has a completely different one Construction. Instead of a swivel lever, a pointed threaded bolt with a head is used here Closing an opening of the extended riser pipe. Opening and closing by twisting the Threaded bolt in the screwing direction is therefore cumbersome and certainly not clear in its effect. On the other hand, it is not possible to do without the closure, because otherwise it will take longer Failure to use volatile components of the liquid can escape into the environment. This lock therefore certainly also requires a cover cap, as is usual with the spray can, because the pipe section, the nipple and the threaded bolt in their entirety leave a rather unsightly impression. Of the The bolt head consists of 5 components, so it is expensive to manufacture. After all, that's too Spraying principle a different one; because here won't

, L

if

the liquid through the pressurized air in the The riser pipe is pushed up and not sprayed through a nozzle in a relaxed manner, but the compressed air passes through lateral holes above the liquid level in the annular tube space and they should obviously through a generated vacuum in the riser pipe suck up the liquid and then with this through an upper hole into the Conveying the environment. A satisfactory, above all uniform, effect of this principle can be considered the lower amount of air that can be pressurized in the top of a filled bottle, and Do not expect the liquid level to drop further and further.

The invention is illustrated below with reference to the drawing of an embodiment of the dispensing closure described in more detail.

The double-walled cap-shaped dispensing closure ί consists of an essentially cylindrical outer wall Γ with an outer surface!

The inner wall ^{/ has} (left half) an internal thread 1>, for screwing the cap ί onto the neck 3 · 'of a container, e.g. B. a bottle 3.

The container 3 has a flexible wall which enables the generation of an internal pressure by alternately pressing and opening the hand clasping it.

The rocker arm 2 contains an Axialbohriing 2 · ', the front end 2 ·' · 'of which is designed as a spray nozzle, upstream of which a conically tapered transition piece 2 ·' ¹ ' is arranged.
