Definitions
- the invention relates to a container made of flexible plastic for attachment to a rigid adhesive surface and a method for attaching the flexible container to the rigid adhesive surface; Furthermore, the invention relates to a method for filling pressurized gas packages, which consist of a pressurized gas container, which contains a pressure medium, and at least one flexible filling bag located therein, which serves to hold the filling material, the interior of the flexible filling bag using of a valve, which is arranged in the region of the opening of the pressure gas container, as well as the pressure gas pack and the valve-bag unit provided with the filling bag.
- pressurized gas packages consist of a pressurized gas container, which contains a pressure medium, and at least one flexible filling bag located therein, which serves to hold the filling material, the interior of the flexible filling bag using of a valve, which is arranged in the region of the opening of the pressure gas container, as well as the pressure gas pack and the valve-bag unit provided with the filling bag.
- Compressed gas packs which are often referred to as aerosol 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 actuating the valve, the filling material and the pressure medium emerge together.
- 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 serve to hold the filling material to be dispensed are filling bags made of flexible material, such as e.g. thermoplastic plastic or aluminum.
- the filling 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.
- All types of compressed gases such as preferably environmentally compatible compressed air, are used as pressure medium, as are gases condensing under pressure.
- All these known two-chamber spray systems have the disadvantage in common that there is an opening in a pressure-resistant pressure gas container at the bottom or in another area.
- the flexible filling bag is suspended on the edge of a mouth provided in the pressurized gas container by squeezing during the closing process.
- the mouth which is standard on the aerosol containers, is widened.
- the filling bag which has a comparatively larger cross section, must be introduced into the pressure gas or pressure medium container with inevitable, temporary deformation. This can result in damage to the filling bag, due to which an undesired mixing of the filling material with the pressure medium can occur.
- the filling process takes place in such a way that the filling material is first filled into the empty filling bag previously placed in the pressure gas or pressure medium container, until the filling bag is returned to its original shape and filled with the filling material.
- valve is put on and the rim of the plate together with the brim
- the mouth of the filling bag is permanently connected to the pressurized gas container by clinching or crimping.
- Air bubbles, enclosed in pasty filling material, are quite annoying because they relax spontaneously when the filling material is discharged, which can cause the strand of filling to burst open.
- the conventional method is particularly complex because the initially unpressurized, closed pressure Pack must be sealed in the region of the second opening already mentioned above in order to apply an overpressure inside between the filling bag and the container wall.
- the desired excess pressure is then generated through this opening with a pressure-increasing medium, such as compressed air or another compressed gas.
- a pressure-increasing medium such as compressed air or another compressed gas.
- the opening must be sealed with a plug, as explained above.
- the invention is based on the object, while avoiding the aforementioned disadvantages, of further improving the generic method and the associated valve unit and compressed gas packing in such a way 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 thus with correspondingly little effort.
- a container made of elastically malleable, flexible material can be created, which can be permanently attached to an adhesive surface in such a way that the parts connected to one another can be handled, stored and transported as a unit.
- this object is achieved in relation to the container with the features of claim 1. Due to the special contours in the area of the mouth of the container, which are adapted to those of the adhesive surface, the container is contracted during evacuation, which is also a pneumatic fastening process, and fixed to the adhesive surface. Secure adhesion is achieved in that the shape of the elastic, flexible plastic container, which is to be connected to the adhesive surface by applying a vacuum, is adapted to the contour of the adhesive surface in the region of the mouth.
- the container is oriented with respect to the orientation with respect to the adhesive surface.
- this constriction ensures that the mouth region of the filling bag adheres securely to the adhesive surface when it is evacuated. If this option for supporting the filling bag on the valve housing was missing, it could occur comparatively frequently that the filling bag Ku réelle contracts in its mouth area, whereby the sealing adhesion of the mouth area of the filling bag on the adhesive surface could be lost.
- the container is designed according to claim 3, it is contracted due to its nature and shape at the moment of the pneumatic fastening and oriented and fixed on the adhesive surface with respect to the shape and orientation according to a predetermined pattern.
- valve unit the object on which the invention is based is achieved by the features specified in claim 4; here the already mentioned adhesive surface is formed on the plate edge of a seat valve for compressed gas packs.
- the flexible plastic container - hereinafter referred to simply as a filling bag for the sake of simplicity - is first lightly pressed onto the underside of the valve plate rim.
- valve-bag unit can be preassembled, stored, transported and introduced manually or mechanically into the mouth of an empty compressed gas container and in a known manner with correspondingly changed values be permanently connected to it by clinching or crimping. Thanks to the contracted shape, which is significantly reduced in volume and cross-section, the valve-bag unit with the filling bag attached to the valve plate can be effortlessly inserted manually or mechanically through the opening of the empty compressed gas pack and then clipped onto the rolled edge thereof.
- the filling bag can be precisely aligned and oriented with respect to the valve plate during the evacuation.
- the filling bag is designed in its shape and profile by bulges and / or by longitudinal grooves in such a way that in the pneumatic fastening process, due to the negative pressure, there is an elongated orientation which is perpendicular to the axis of the adhesive surface and the bag has a multi-pointed star shape Strand, a flat pressed, slightly curved, elongated bladder or another shape that can be predetermined by the shape of the filling bag is drawn together.
- the cross section of the filling bag is significantly reduced;
- the filling bag attached to the valve is formed, for example, when three or more longitudinal grooves are made in the fuselage area as a straight, multi-point star-shaped strand which is oriented perpendicular to the valve disk.
- the filling bag deforms after the application of the negative pressure to form an elongated, slightly curved, flattened bladder which can be easily wound together.
- valve-bag unit designed as a one-piece component considerably simplifies the assembly of the compressed gas package according to the invention.
- the method specified in claim 11 for producing the valve-bag unit according to the invention after the valve has been sealed by relieving the spring socket and releasing the external overpressure, the contracted filling bag under the effect of the negative pressure prevailing in its interior becomes so strong the Haf surface noted that it can only be removed by applying a tractive force that exceeds the considerably high suction force.
- the method according to the invention therefore differs from all known methods used in two-chamber systems in that the filling bag is emptied of air before filling with filling material.
- the desired orientation of the filling bag with respect to the valve disk is achieved.
- the constriction ensures that the filling bag is firmly fixed to the valve plate during the evacuation. If this possibility for supporting the filling bag on the valve housing was missing, it could occur comparatively frequently that the filling bag was in its place when it was evacuated Mouth area contracts, whereby the sealing adhesion of the mouth area of the filling bag on the underside of the valve plate could be lost.
- the object on which the invention is based is achieved according to the invention by the features specified in claim 13. Due to the volume increase of the filling bag filled in the filled compressed gas container, an overpressure is generated in the space between the inner wall of the compressed gas container and the now extended filling bag, without such overpressure as described in connection with the conventional so-called two-chamber method an additional opening in the pressurized gas container would only have to be built inwards.
- the filling material does not come into contact with the inner wall of the container and can be metered into the filling bag in the compressed gas container with the exclusion of air.
- the procedure proposed according to claim 14 prevents the filling bag inside the compressed gas container from being damaged by external stresses on the latter, such as can occur during transport and handling, by striking the inner wall of the compressed gas container.
- through extensive Filling the interior of the pressurized gas container by the filling bag increases the excess pressure available for expelling the filling material.
- stretching the flexible, preferably thermoplastic, material of the filling bag can improve its molecular structure and physical properties, in particular its permeability.
- a diffusion such as has occurred in the course of time with known unstretched filling bags, no longer takes place. Due to the expansion of the bag during the filling with the filling material, it is brought into contact with the bottom of the compressed gas container and / or with its inner wall, which also results in a firmly anchored seat of the filling bag in the compressed gas container.
- Figure 1 is a side and bottom view of a Filling bag attachable to a valve plate
- FIG. 2 shows a valve unit comprising a valve plate, housing, element and filling bag
- valve unit 3 shows the valve unit inserted into a compressed gas container
- FIG. 4 shows the valve unit inserted into the compressed gas container, the filling bag being filled.
- the valve unit 4 shown in FIG. 1, designed as an aerosol valve, has a valve plate 3, a valve element 9 designed as a spring socket, a valve housing 8, which is crimped onto the valve plate 3 and in which the spring socket 9 is received, and a filling bag 2.
- the filling bag 2 is not yet attached to the valve plate 3.
- the filling bag 2 consists of a flexible plastic material, preferably made of polyethylene, is approximately cylindrical in its basic shape and has a convex downwardly curved base region 20 and a body 19 adjoining it. Above the body 19 there is an inlet Lacing 13 formed, which merges into the trunk 19 in an extension area 18. At its top end it goes Constriction 13 in a widening mouth area 1 over; the mouth region 1, following the constriction 13, initially has a radially widening subsection 21, an adjoining, approximately cylindrical middle section 24 and a circumferential and trough-shaped brim 5 adjoining the middle section 24 at the top.
- inwardly indented longitudinal grooves 14 which extend into the bottom area 20 of the filling bag, and outwardly protruding bulges 22, which extend into the extension area 18 of the filling bag 2, are formed .
- the valve plate 3 is trough-shaped at its plate edge 6.
- the shape of the lower surface 15 of the valve plate 3 corresponds to the brim 5 of the filling bag 2.
- a circular shape (not shown) can be shown be arranged sealing lip.

- the inner surface of the constriction 13 of the filling bag 2 comes close to or even in contact with the outer surface of the valve housing 8.
- the spring socket 9 is pressed into the valve housing 8 by means of a hollow needle 7; A vacuum is applied to the valve housing 8 from the outside, whereupon the interior 17 of the filling bag 2 is evacuated.
- the mouth region 1 of the filling bag 2 adheres firmly to the lower surface 15 of the valve plate 3, the brim 5 and the approximately cylindrical central section 24 of the mouth region 1 in particular firmly adhering to the lower surface 15 of the valve plate due to the effect of the negative pressure 3 are pressed.
- the inner surface of the constriction 13 also comes into firm contact with the outer surface of the valve housing 8, which results in the evacuated filling bag 2 being positioned approximately perpendicular to the valve disk 3. Due to its Ausbil ⁇ dung to the four longitudinal grooves 14 and the four lobes 22, the cross sectional shape of the filling bag 2 in darge presented embodiment of the evacuation, the shape shown in Figure 2 below to •.
- the filling bag 2 By appropriately shaping the filling bag 2, it can assume any desired shape after the evacuation.
- the hollow needle 7 After evacuation, i.e. after the interior 17 of the filling bag 2 has been vented, the hollow needle 7 is withdrawn. Due to the spring tension of the spring socket 9, the valve housing 8 is automatically closed. The filling bag 2 adheres firmly to the lower surface 15 of the valve plate 3 with its mouth region 1. A separation is only possible by applying an enormous tensile force and is therefore very unlikely.
- valve or valve-bag unit 4 shown in FIG. 2 is thus produced after the evacuation. This can be stored, transported and further handled as a single component.
- valve-bag unit For installation in a compressed gas pack, the valve-bag unit is opened through the opening 16 in an end face of a cylinder.

- the shape of this rolled edge 11 is such that it lies flat against the trough formed by the brim 5 or the plate edge 6.
- an O-ring seal 12 can be inserted at the apex of the trough.
- valve-bag unit 4 After the valve-bag unit 4 has been inserted into the compressed gas container 10, the latter is filled with the compressed gas.
- the valve-bag unit 4 is raised slightly from the position shown in FIG. 3 with respect to the compressed gas container 10.
- an intermediate space is formed between the outer side of the mouth region 1 of the evacuated filling bag 2 adhering to the lower surface 15 of the valve plate 3 and the rolled edge 11 of the compressed gas container 10 surrounding the opening 16.
- the inner space 23 of the compressed gas container 10 is filled with the compressed gas through this intermediate space.
- the valve-bag element 4 is held magnetically, pneumatically and / or mechanically in the position forming the intermediate space.
- the filling of the compressed gas container 10 with compressed gas is continued until the entire interior 23 of the compressed gas container 10 surrounding the evacuated filling bag 2 is filled with compressed gas. Thereupon the valve-bag unit 4 is completely inserted into the compressed gas container 10.
- the mouth area 1 of the filling bag 2 connected to the valve 3 lies with the brim 5 on the rolled edge 11 of the compressed gas container 10.
- the plate edge 6 of the valve plate 3 is clinched to the rolled edge 11 of the compressed gas container 10.
- the O-ring seal inserted between the brim 5 and the rolled edge 11 fits sealingly between the underside of the brim and the rolled edge 11.
- the pressure gas container 10 is filled with pressure medium or gas under a defined overpressure, which can be done by using an overpressure filling head known per se, this defined overpressure is maintained until the valve-bag unit 4 with the evacuation ten filling bag 2 has been attached or clinched on the compressed gas container 10 in the manner described above. As a result, a defined excess pressure can be presented in the interior 23 of the compressed gas container 10. The overpressure in the interior of the pressure gas container 10 increases by this overpressure beyond the overpressure generated by the introduction of the liquid or pasty filling material and by the overexpansion of the filling bag.
