Definitions
- the invention relates to a method for filling Druck ⁇ gas packs, which consist of a housing containing a Druckmit ⁇ tel, and at least one flexible bag located therein, which serves to hold the filling material, the interior of the flexible bag by means of a venti ] s, which is arranged in the region of the mouth of the housing, and the compressed gas pack.
- Containers are known, in which the filling material and the pressure medium are mixed with one another, dissolved in one another and / or dispersed. After the valve is actuated, the filling material and the pressure medium emerge together.
- the compressed gas packs are so-called two-chamber spray systems in order to avoid that the filling material comes into contact with the housing and / or with the pressure medium.
- a metal or glass housing is used as the outer container, as has been used as an aerosol container for decades for filling goods as personal care products, hair care products, insecticides, impregnation sprays and technical aerosols etc.
- the inner containers which are used to hold the filling material to be dispensed, are bags made of flexible material, such as thermoplastic plastic or aluminum. The bag, which is under the excess pressure of the pressure medium, is compressed when the pressure is released, the filling material then being conveyed out of the valve opening of the compressed gas pack by actuating a valve in spray form, as a foam or paste strand.
- compressed gases such as preferably also environmentally compatible compressed air, are used as pressure medium, as are gases condensing under pressure.
- the object of the invention is to further improve the generic method and the associated compressed gas pack, while avoiding the aforementioned disadvantages, so that not only any pressure medium, in particular air, but also commercially available containers can be used and the entire filling process can be carried out in a comparatively short time and therefore with correspondingly little effort.
- this object is achieved with respect to the filling method in that the flexible bag is inserted into the Housing is introduced such that there is a gap between the opening edge and the mouth of the housing that the pressure medium is introduced through the gap between the opening edge of the bag and the mouth of the housing that the opening edge of the bag together is tightly closed with the valve with the mouth of the housing, that the valve is actuated to evacuate the interior, and that after the valve is actuated again, the contents are filled into the bag under pressure.
- the invention further extends to a compressed gas pack which consists of a housing which contains a pressure medium and at least one flexible bag located therein which serves to hold the filling material, the interior of the flexible bag being closed by means of a valve which is arranged in the region of the mouth of the housing.
- the flexible bag be used as a fold bellows is designed such that its folds fold inwards, so that a comparatively large interior space is available for receiving the pressure medium.
- a glass bottle is used as the housing 1, which is surrounded by a shatterproof plastic covering.
- the bag 2 is inserted in the form of a bellows.
- the bag 2 consists of thermoplastic material, for example polyethylene.
- the bag 2 is introduced into the "housing 1 in such a way that there is an intermediate space 5 between the opening edge 3 and the mouth 4 of the housing 1.
- the bag 2 projects beyond the mouth 4 of the housing 1, the valve 6
- the pressure medium is now filled in through the space 5 between the opening edge 3 of the bag 2 and the mouth 4 of the housing 1, namely via a top of the mouth 4 of the Housing 1 attached filling head.
- the pressure medium penetrates into the space between the inner wall of the housing 1 and the outer wall of the bag 2.
- the valve 6 is crimped onto the mouth 4 of the housing 1, the opening edge 3 of the bag 2 being squeezed between the mouth 4 of the housing 1 and the valve 5.
- FIG. 2 By actuating the valve 6 (FIG. 3) and preferably by applying a vacuum, the bag 2 is completely evacuated, so that it contracts to a considerably smaller volume and the overpressure between the bag 2 and the housing 1 is reduced. There is therefore no residual air in the bag 2.
- the compressed gas pack prepared by these process steps can either be stored and thus marketed or can also be filled directly with the filling material.
- the bag 2 By pressing the filling material (FIG. 4) under pressure, the bag 2 expands under the excess pressure when the filling material is pressed in, at the same time the pressure medium in the housing 1 is increased in pressure.
- the bag expands through the introduced filling material, but no air bubbles can penetrate, so that a flickering or short interruption of the spraying which often occurs in the known two-chamber spraying systems jet or strand in pasty filling goods due to escaping gas bubbles is definitely excluded.
- the ratio of the volume of the filling material to the volume of the expanded bag is essential.
- the bag only partially holds the intended filling material, so that the remaining part of the filling material is pressed in by force under the mechanical pressure of the pressure medium while the flexible material is stretched. Due to its flexibility, the bag takes up a larger volume than the previously folded bag. As a result, the intended overpressure of the pressure medium is increased in a controlled manner in the space between the housing and the bag.
- This stretching of the flexible material of the bag preferably thermoplastic material, improves its molecular structure and physical properties, in particular its permeability. Surprisingly, it was found that diffusion, such as occurred over time in known unstretched bags, no longer takes place.
- the housing 1 of an aerosol tin can with inserted bag 2 and valve 3 in the form of a poppet valve is shown.
- the bag 2 with the plate of the valve 6 is pressed into the housing 1, the sealing being carried out by clinching.
- the opening edge 3 of the bag 2 between the plate of the valve 6 and the mouth 4 of the housing 1 ( Figure 7).
- the bag 2 is completely evacuated (FIG. 8).
- the bag 2 expands (FIG. 9) and assumes the compressed form again after its contents have been emptied (FIG. 10).
- the gassing of the space between the inner wall of the housing and the outer wall of the bag can be carried out in a simple manner with all types of pressure medium in an independent process, so that the empty housings under internal pressure are temporarily stored, marketed or subsequently filling goods can also be loaded immediately later, if necessary;
- aerosol containers are disposable containers and are not intended for commercial refilling.
- the housings used are not subject to the compressed gas regulation, it is possible with the aid of the method according to the invention to empty these containers after complete emptying, i.e. after use, refill with fresh product.
