Definitions
- the invention relates to a two-chamber package with an essentially dimensionally stable outer container (1) for a liquid or pasty filling material provided with a dispensing valve (2), and an inner container for a compressed gas, such as compressed air, nitrogen, arranged in the outer container (1). or the like, wherein the inner container (3) is designed as a flexible bag, and wherein the dispensing valve (2) comprises a dispensing tube (17) movably mounted in a valve body (14) from a closed position into an open position and vice versa.
- the present invention has for its object to provide a two-chamber pack of the type mentioned, which is simple in construction, permanently reliable and highly environmentally friendly.
- the two-chamber pack according to the invention is characterized by a multi-functional dispensing valve. On the one hand, it serves
- the filling material can be discharged in the outer container via this dispensing valve.
- the two-chamber pack according to the invention is therefore a self-contained, particularly simple and reliable construction which is significantly less polluting than the known proposals.
- the free space delimited by the filling material on the one hand and the walls of the outer container and inner bag on the other hand is largely evacuated in order to form an air cushion in the region of the container-internal part of the dispensing valve or before access to it, which impairs the dispensing of the filling material Avoid dispensing tubes.
- the evacuation is preferably carried out before the container lid is crimped on.
- the design of the dispensing valve according to claims 9 et seq. Is of particular importance, regardless of the construction described above.
- the features described there enable the double function described above of the dispensing valve in a very simple and reliable manner.
- the elastic element in the form of a helical compression spring urging the dispensing tube into the closed position has a dual function, namely, on the one hand to urge the dispensing tube into the closed position, and on the other hand, the closing plug for the
- the closing plug which is arranged displaceably within the valve body of the dispensing valve, also has a double function, namely on the one hand to close the filling opening which opens into the inner bag for the fumigation of the same, and on the other hand during the fumigation of the inner bag
- Pasty materials such as ketchup, cream, mayonnaise, skin cream, or the like, or liquid substances, such as hair colorants, eau de cologne, or the like, are suitable as filling material.
- the two-chamber pack according to the invention is assembled in such a way that the contents are first filled into the outer container.
- the inner bag is then rolled up or folded in the longitudinal direction and inserted through the upper container opening into the outer container, with the inner bag being stabilized or increased in order to stabilize or buckle it.
- Riser tube is provided, which is connected to the filling opening of the valve body opening into the inner bag.
- the inner bag is already connected to the dispensing valve during this process.
- the container lid is crimped onto the opening edge of the outer container in a manner known per se with simultaneous evacuation of the space between the outer container, inner bag and lid, so that when the inner bag is fumigated, the filling material goes up to the dispensing valve without any training can evade a larger air cushion.
- a discharge or spray head is mounted in a manner known per se at the free end of the dispensing tube. Since this is a component which is known per se, a detailed description of the same is unnecessary here.
- the inner bag is gassed through the dispensing valve or dispensing tube. After this process has been completed, the dispensing tube is pressed further into the interior of the container while the closing plug mentioned above is moved into the filling opening-closing position.
- the inner bag filled with compressed gas is hermetically sealed from the environment.
- the two-chamber pack is ready for use.
- the inner bag filled with compressed gas preferably fills approximately 1/3 of the interior of the outer container.
- the pressure gas filled is under a pressure of about 9 bar. 2/3 of the interior of the outer container is filled with filling material.
- outer container is shown in section along line II-II in Fig. 1, while the inner bag together with the dispensing valve in side view is shown;
- FIG. 3 shows a first embodiment of a dispensing valve designed according to the invention in longitudinal section and on an enlarged scale before assembly on the outer container;
- FIG. 4 shows the assembled dispensing valve corresponding to FIG. 3
- FIG. 5 shows a part of the dispensing valve according to FIG. 4 under
- FIG. 6 shows the discharge valve of FIG. 4 in cross section
- the filling material and its closure can be filled with compressed gas, so that when the dispensing valve 2 is open, the filling material can be squeezed out of the outer container 1 with appropriate expansion of the inner bag 3, namely through the dispensing tube 17 already mentioned.
- the inner bag 3 extends, as can be seen in FIGS. 1 and 2, essentially over the entire length of the interior of the outer container 1 and is cut and folded in such a way that it essentially completely fills the interior of the outer container 1 Hose expands, namely - as can be seen in FIG. 2 - progressively from the bottom 4 of the outer container 1 to the dispensing valve 2.
- the inner bag 3 is formed by a multilayer film of the above-mentioned type which is folded over one another, welded or sealed at the edges, the bottom being folded such that when the inner bag 3 is filled with compressed gas, an essentially flat bag bottom 5 is formed, which is formed extends over the container bottom 4. This is to ensure that as little residual filling material as possible remains in the bottom region of the outer container 1 and that the container 1 is emptied essentially completely starting from the bottom 4.
- the formation of a flat bag bottom 5 can be achieved, for example, by folding the bottom of the inner bag 3 such that it comprises an inward V-fold 6 which extends transversely between the two diametrical longitudinal sealing edges 7 and 8 of the inner bag 3. At its diametrical ends, the V-fold 6, in continuation of the two longitudinal sealing edges 7 and 8, is delimited by sealing edges 9, 10 and 11, 12 directed obliquely inwards. 2 are the Sealing edges 11, 12 each not visible behind the sealing edges 9 or 10.
- the additional sealing connection 13 extends from the upper or the
- Dispensing valve 2 facing the end of the inner bag 3 over approximately 2/3 of the total length of the inner bag 3, the additional sealing connection 13 being formed by two sealing strips which extend parallel to one another and at a distance from one another.
- the sealing strips can also be interrupted, in particular can only be effective at certain points.
- the strength of the additional sealing connection 13 in the direction of the dispensing valve 2 is preferably increasingly greater, as a result of which the targeted progressive expansion of the inner bag is promoted from the bottom upwards.
- a spray head 28 with a spray nozzle 29 is also arranged.
- Component is a generally known construction element, the detailed description of which is therefore not necessary.
- valve body 14 of the dispensing valve 2 extends - sealed against the interior of the outer container - into the inner bag
- valve body 14 has an opening that opens into the interior of the inner bag 3
- Inner bag 3 takes place and which after gassing or filling the inner bag 3 with compressed gas through the dispensing valve 2 or its dispensing tube 17 can be closed by means of a closing plug 18.
- the closing plug 18 is designed so that in the starting position, i.e. in a
- Position for filling the inner bag 3 with compressed gas closes a passage opening 20 connecting the interior of the outer container 1 with the interior of the valve body 14, so that the fluid connection between the interior of the outer container 1 accordingly and the discharge tube 17 of the discharge valve 2, which is axially displaceably mounted in the valve body 14, is interrupted during the gassing or filling of the inner bag 3 with compressed gas.
- An axially effective elastic element in particular a helical compression spring 19, is arranged between the closing plug 18 and the dispensing tube 17, against the action of which the dispensing tube 17 can be pushed axially into the valve body 14 with the release of a fluid connection, the closing plug 18 being used to fill the inner bag 3 with compressed gas inside the valve body 14 is held in a starting position raised from the filling opening 16 opening into the inner bag 3, in which the compressed gas can be introduced into the inner bag 3 through the dispensing tube 17 pressed axially into the valve body 14 and past the closing plug 18 on the outside ( see flow arrows 30 in FIGS. 4 and 5). After filling the inner bag 3 with compressed gas, the closing plug 18 is moved according to FIG.
- the closing plug 18 is made of a harder material, in particular plastic material, such as rigid PVC, than the valve body 14. According to the illustrated embodiment, the
- Closure plug 18 on the side facing the dispensing tube 17 has a pot-like guide sleeve 25, into which the part of the helical compression spring 19 facing the interior of the container extends and whose outer peripheral edge 26 facing the dispensing tube 17 protrudes radially outwards with sharp edges in order to be supported on the inside of the valve body 14 laterally limiting peripheral wall 27 to complicate a movement of the closing plug 18 out of the filling opening-closed position according to FIG. 7.
- the closing plug 18 is accordingly both by the helical compression spring 19, the sharp-edged peripheral edge 26 and the radially inwardly projecting locking projection 24, which interacts with the radially outwardly extending ring projection 23 of the stopper 18, held.
- Circumferential ribs are formed through a plurality of through openings 33 which are distributed uniformly over the circumference and through which the compressed gas flows into the inner bag 3 (arrow 30 in FIG. 5).
- the axial movement of the dispensing tube 17 takes place through a filling head, not shown in detail.
- the dispensing valve 2 or its valve body 14 is anchored centrally to the container lid 34 in a manner known per se. For this reason, a more detailed description of this mounting structure is not required.
- Length of the inner bag 3 extends. As stated at the beginning, this riser serves essentially only to increase the kink stability of the inner bag 3, so that it can be more easily immersed in the container 1 filled with the filling material, especially if the filling material is a pasty mass.
- FIG. 9 An alternative construction of the dispensing valve with respect to the closing plug 18 is shown in FIG. 9. Parts of the dispensing valve 2 already described with reference to the preceding figures are identified in FIG. 9 with the same reference numerals. With regard to their function, reference is therefore made to the preliminary description.
- the special feature of the embodiment according to FIG. 9 is that the guide sleeve 25 is tight over the entire circumference on the inside of the valve body 14 laterally delimiting circumferential wall 27. Accordingly, through openings 21 are arranged in the bottom of the pot-shaped guide sleeve 25 for gassing the inner bag 3, through which the inner bag 3 is fumigated when the stopper 18 is lifted from the filling opening 16 (see arrows 30).
- the dispensing tube 17 is pressed even further into the container by the filling head, not shown, bearing against the projection 32 described above. During this movement, the radial ribs 22 are pressed into the clamping sleeve 24, so that the closing plug 18, which is likewise pressed into the filling opening 16, is held in the filling opening-closed position.
