1 2 This object is achieved in the case of the container of the type described above in that the device consists of a mass for exerting the pressure 1. Container with at least one valve for the compressible foam with closed cells filling with and dispensing of a doughy, 5 consists. ,
liquid or as an aerosol through the action of pressure The resulting advantage consists in the fact that the fluid medium to be distributed and a device in the interior of the container for exercising an aerosol container to be filled is obtained an enormous simplification in the production, whereby the pressure on the medium to be distributed is produced exclusively in the insertion of a characterized in that the device consists of a piece of foam in the still empty socket before the device for exerting the pressure from a closure. Compressible foam compound (6) with closed cells. Sible foam is made from plastic. Suitable 2. Container according to claim 1, characterized thereby, foams made of polyethylene, neoprene draws that the compressible foam made of 15 or polyurethane. Made of plastic. On the basis of the drawing, for example Embodiment of the invention explained in more detail.
F i g. 1 shows schematically in section a container before filling the flowable medium; 20 Fig. Figure 2 shows the container of Figure 2. 1 after filling the medium. The container 1 shown in the drawing consists The invention relates to a container with little from a cylindrical jacket 1 a, which has a valve for filling with and the bottom 1 b along a bead 2 ben from a doughy, liquid or aerosol through 25 at the bottom is closed, while its upper part 3 tapers conical pressure action to distribute flowable Me- and 3m tapered end to a plate 4 dium and a. Device in the interior of the container for being closed by crimping, in which the pressure exerting the pressure on the part 5 to be distributed sits in the center. In the container 1, a cylinder 6 made of podium, lyäthylenschaum with closed cells is arranged Such a container for spraying 30 net and at a point 6 ft at the bottom 1 b of the container liner contained therein liquid is already known, in which ters 1 attached in a fixed position. The foam line is accommodated in an elastically deformable structure, which fills almost the entire volume of the container 1, which can be inflated by supplying a propellant gas. out. It is in the container 1 after attachment of the propellant gas is arranged in a b of the container with the bottom 1 young end before the preparation of the conically verzu sprayed means separate own container 35 part 3 on the ^ O at eite,
housed. By means of a regulating device, the propellant gas is introduced into this container through the valve 5 with the interior of the bellows-like inflatable medium 7 under pressure, whereby the expandable structure can be brought into connection. By the volume of the foam cylinder 6 the Trcibmittelbehälter will always be "only blowing g to in F i. Volume 6 shown 2 α decreases, gas tracked in the bellows when the pressure 40 by means of the mounted on the valve 5 press- Volume decrease as a result of the spraying of button 8, the valve can be opened, whereby the liquid is too little liquid for the further spraying effect, the medium 7 is released due to the pressure This case has the reduced pollutant cylinder 6 α is exercised. Disadvantage that when the bellows-like 45 is inflated, the flowable medium 7 is released so that the structure can form folds which tend to tear until the foam cylinder 6 is again Execute so that the propellant gas has reached the duct volume to be distributed. The volume reduction liquid escapes it is necessary to readjust the pressure in the bellows from the foam cylinder to the pressure foot outside by 40 to 70% of the pressure with the flowable medium. so that a separate propellant gas volume 50 initial volume. container, which is to be distributed on the actual container for the The following example serves to further elucidate ! endc liquid is formed, is required. purification of the invention.
The resulting manufacturing effort is very great, in addition, need to follow example during operation
regulicrungcn are made. 55 It is also known, in a pressure bottle, a The arranged in the container foam cylinder elastic member made of foam rubber one of the 6 consists of nitrogen-foamed polyethylene add, with the help of which overpressures in the bottle hylen with closed cells and has a volume can be recorded, for example, from 240 cm x ¹ . Valve 5 is considered to be justifiable by means of a Tempering, flowable medium caused by exposure to the sun, eau de cologne increase in temperature occur. For the expulsion of the 60 ° C supplied ^{at a pressure of 4.8 kp / cm 2.} Liquid from the pressure bottle is this link per- This compresses the foam cylinder 6 but not usable. miert until it has a volume of about 100 cm ³ . In The object on which the invention is based, in the case of the container, is then 150 cm ^{3 of} eau de cologne It therefore contains a container that initially contained 65 60 ° C. Pressing button 8 will called type to create, the structure of which especially from the container 1 an aerosol of eau de cologne easily and therefore suitable for series production, it is almost the entire delivery of the > t. filled eau de cologne possible.
