Description

TUBE-FORMED DOSAGE TANK

The present invention relates to a metering container for the delivery of pasty or viscous product by manual pressing on the container. Corresponding containers are also referred to as tubes, which can be emptied by pressing on the outside.

Corresponding tubes are common for toothpaste, tomato paste, mayonnaise, mustard and the like. Generic tubes may consist of a metal foil. Toothpaste tubes are known which are formed from a foil material, which is initially formed circumferentially to a tube and are closed at the end remote from the removal opening by welding the tube. On the opposite side of a removal opening forming container head is provided.

In tube-like containers of the generic type, among other things, there is the problem of emptying the tube as completely as possible. Especially with tubes made of plastic material, there is still the problem that, although the contents can be emptied by pressing against the tube outer surface. A discharge, however, inevitably leads to the provision of the tube in the original shape and thus for sucking air into the tube.

Not all products sold in tube-like dosing containers can withstand prolonged storage under an oxygen-containing atmosphere. For example, mustard under the influence of oxygen shows a negative sensory change and accelerated aging.

On the other hand, it may also be desirable to create a certain suction in the tube by returning the tube, so that product located at the removal opening will not be released unintentionally. Such a characteristic should have the metering container in particular when an exact dosage of the container contents is desired.

Basically there is a need to produce dosing as cost effective. In this respect, a high degree of automation and a far-reaching standardization of the dosing is conducive to different applications. On the other hand, different requirements are placed on dosing in practice, which runs counter to standardization in particular the production of dosing. The present invention has for its object to provide a dosing, which is optimally adapted in view of the problems described above.

To solve this problem, the present invention provides a metering container having the features of claim 1.

The present invention is based on a metering container, as it is known for example from DE-A-24 60440. This prior art discloses a metering container having two substantially parallel side walls which are spaced from each other by two end walls and connected together. The front side walls have at least one side fold through which the end side walls are subdivided into at least two front side wall segments which can be applied against one another and / or the inside of the side walls. The side walls are connected to each other at an end remote from the discharge opening and abut there against each other. The end wall segments are turned inwards. Furthermore, a removal opening is provided on a substantially perpendicular to the side walls extending container head.

Although the previously known metering container can be emptied as best as possible due to its container shape, since the end side wall segments can be placed on the inside with increasing emptying each other or on the opposite side walls, resulting in an almost complete emptying of the metering. However, the prior art dosing tank has no recovery properties that prevent air from being sucked in or favor precise metering in dispensing product from the dosing tank.

Here, the present invention remedy by proposing to form the dosing of a sheet material, which is connected to a shoulder element. The shoulder element surrounds the removal opening and creates predetermined functional surfaces on the otherwise sheet-like film material, which has usually been converted into a receiving tube by folding and welding (longitudinal welding seam) of the layers. By welding (transverse weld), the film material can be closed on one side. On the opposite side of this weld is usually the shoulder element which surrounds the removal opening. The shoulder element can form a container head which extends substantially perpendicular to the side walls and forms a removal opening which is small in cross-section compared to the container cross-section at this side. AI Alternatively, the shoulder element can also have functional surfaces for fastening a cap or an applicator approximately at the height of the foil material, ie in the region of the outer circumference of the shaped foil material. Such functional surfaces may be formed, for example, by a contour provided on the outer circumferential surface of the shoulder element, against which a container head, an applicator or a container lid is secured. The connection can be made for example by wringing cap or applicator against the outer contour.

Since the shoulder element is formed by injection molding, can be formed with this very complex units and then connected to the film material. In this way, a container can be produced relatively inexpensively, which meets the individual requirements. The majority of the container, i. In particular, the container volume is provided by the relatively inexpensive film material, whereas only the shoulder element by means of injection molding and high-quality, but in any case compared to the film material thick-walled plastic is formed.

A plastic film in the context of the present invention is in particular a film having a thickness of less than 1 mm, preferably less than 0.1 mm. Preferably, it is a coextruded film with different layers. The film usually consists exclusively of polyolefins such as PE, PP, PVC or PS.

In the embodiment of the shoulder element together with the container head can be impressed by the geometric configuration of the first no predetermined elasticity having foil material a certain resilience. Thus, the film material of the dosing can be elastically deformed during molding of the shoulder element in a predetermined manner. It is possible to preform the film material in such a way when attaching the shoulder element, that the side walls lie centrally against each other and abut the end side wall segments against each other or edge on the inner surface of the side walls. When connecting the film material with the shoulder element in this position, the film material is given a tendency to deform with increasing emptying of the dosing to the inside. The film material can thus promote an output of product from the metering, but in any case prevent that after the delivery of material from the metering this elastic restores and sucks air. In the same way, the foil material can be kept in a inflated state when the shoulder element is fastened. When tying the shoulder element to the film material, this inflated, ie given relatively large volume orientation of the film material. Accordingly, the dosing container has a tendency to form a relatively large internal volume. After delivery of product, the side walls are elastically removed from each other, so that in the region of the removal opening product is sucked inwards into the dosing.

This dosing container according to the invention has two opposing side walls which regularly form the main side walls of the dosing and converge slightly converging, from the end having the removal opening to the opposite end thereof. At this the side walls collide. In the side view, a correspondingly shaped container may have a wedge-shaped configuration. It is also conceivable, however, a substantially rectangular configuration, wherein the side walls are formed to converge toward each other only in the rear, closure-side end region of the dosing.

The container according to the invention further has end walls which connect the opposite side walls together. These end walls are subdivided into at least two end wall segments, between which there is a gusset and which can be applied against one another and / or the inside of the side walls. The particular configuration of the two front side walls accordingly leads to the possibility of the dosing container to fold up bellows-like in the area of the front sides. In this case, the end wall segments first approach each other. In the conventionally implemented embodiment in which the end-face wall segments are turned inwards and the gusset is within an envelope surface which encloses the circumference of the dosing container in a cross-sectional view, the end-face wall segments approach each other with their outer surface as the dosing container is increasingly emptied the inner surfaces of the respective end sidewall segments increasingly approach the inner surfaces of the sidewalls. This approach can be assisted by suitable biasing of the material forming the container, so that the dosing container has the tendency to automatically reduce its volume due to the juxtaposed end-face wall segments.

With increasing emptying of the metering container, this is folded in the region of its front side walls, whereby the inner surfaces of the side walls abut each other. and the filling volume decreases continuously. This return movement into a folded state can also be promoted by suitable shaping of the end wall segments and at the connecting lines between these segments and the side walls such that the dosing container increasingly closes from the rear closed end in the direction of the removal opening by folding.

The metering container according to the invention is predominantly formed from a film material and preferably exclusively from plastic. This film material can be produced, for example, by injection molding, blow molding or, preferably, by longitudinal welding and folding of a supplied film web. The film material can be designed to form barrier layers, in particular for the case in which food is to be received in the dosing container, in a multi-layered manner. The barrier layers prevent the penetration of oxygen and / or UV radiation into the container. The film material and the shoulder element can be joined by means of injection molding, welding or gluing.

With regard to good recovery properties of the metering container is proposed according to a preferred embodiment of the present invention to form stiffening ribs on the side walls. These stiffening ribs are formed so as to restore the recovery of the container to the initial position, i. the situation that would take an unfilled container with open removal opening improves. The stiffening ribs are preferably formed longitudinally and on the outside of the container. It has proven to be expedient to provide two stiffening ribs on each side wall, at the edge. In the region of each, extending in the longitudinal direction of the dosing edge therefore preferably corresponding stiffening ribs are formed. The stiffening ribs may also be essential to the invention, i. together with the above-mentioned features characterize the invention.

It should be noted in principle that all, preferably by way of injection molding together with the shoulder element formed functional elements can be provided on the inside of the dosing, so that it first awakens the impression of a conventional tube packaging. Only when in use, the special restoring properties of the tube causing functional elements of the dosing be perceived by the user. The stiffening ribs, like the shoulder element, can be connected to the film material by means of injection molding or by welding. Preferably, the stiffening ribs and the shoulder element are formed in the same operation on the film material.

In view of the fact that, at the end of the film material remote from the removal opening, it is usually welded together to close the container and optionally thickened to form a flag, according to a further preferred embodiment of the present invention, the stiffening ribs are provided at their ends remote from the removal opening to open into a container reinforcement, which extends transversely to the longitudinal direction of the container. Surrounded in this container reinforcement or by this container reinforcement, usually a hole passes through the flag. This hole can be used to hang the dosing and be penetrated by a rod that holds several dosing hanging.

According to a further preferred embodiment of the present invention, a cover closing the container head is provided, which is integrally formed on the shoulder element and connected via a film hinge with this. This aspect can be essential to the invention. The specified solution is characterized by the previously known, that the lid is integrally provided on the shoulder element, which in turn is integrally connected by encapsulation or welding with the film material of the container. Usually, in the prior art, the container is molded together with the container head by way of injection molding. At this first component, a second component is attached, which forms the lid and forms a pivotally connected to the cover lid base, which is connectable to the container head.

In view of a good handling of the metering container according to the invention, it is proposed according to a further preferred embodiment of the present invention, on both side walls container head side form the foil material stiffening handle elements. These gripping elements extend, for example, over approximately 5 to 25% of the longitudinal extent of the film material and are usually formed during injection molding of the shoulder element. The gripping elements are usually connected to the side walls with the film material. Usually, the connection is made over the entire surface, so that the movement of the grip elements is transmitted directly to the film material. The gripping elements are particularly preferably mounted pivotably about a pivot axis which runs parallel to a abutting edge of the side wall and the container head. The grip elements are read Accordingly, essentially in the area of the front edge of the pivot. The grip elements not only cause a stiffening of the film material, but usually dominate the film material on a certain Rückstellneigung. In this case, the grip elements can act on the film material in such a way that the metering container is returned to a large initial volume. Just as well, the grip elements can promote an automatic collapse of the dosing.

Although the present invention offers the possibility of first forming functional elements of the container or functional elements which can be provided for use with the container or its contents, as part of the injection-molded shoulder element. However, such functional elements can just as well be plugged onto a unit consisting of a shoulder element and a foil material which, for example, also comprises the container cap. Here it is possible to plug or weld the other functional elements. It is intended in particular to a connection by means of predetermined breaking point, which is designed such that a functional element, which is provided for use with the contents of the container, can be solved by manual shearing.

According to a preferred embodiment, the gripping elements are formed continuing a contour of the lid in the longitudinal direction of the dosing. In the longitudinal direction of the metering accordingly results in no discontinuity between the handle elements and the lid. Not least with regard to the stiffening of the side walls of the cover has at its corresponding to the side walls of the container formed lid side walls elevations whose contour is continued by the handle elements.

The grip elements preferably project beyond a bearing surface formed by the shoulder element for the cover. This contact surface interacts with the frontal and container end of the lid. The protrusions formed on the lid are offset inwardly with respect to the lid, so that the part of the gripping elements projecting beyond the contact surface projects beyond the phase boundary between the shoulder element and the lid, while passing directly into the elevation. By extending the grip elements beyond the contact surface, the stiffening and restoring effect caused by the grip elements can be improved. The thickened material of the handle members preferably continues to stiffen the container head thereon in a radial extent relative to the container interior. Depending on the desired metering characteristic, the gripping elements can be connected to the side walls. However, the stiffening effect can already be achieved if the gripping elements are assigned only to the side walls without being directly connected to them. The stiffening effect of the handle elements occurs when a user presses from the outside against external gripping elements. If the gripping elements are formed separately from the film material, this offers the possibility of allowing the gripping elements to be pivoted back separately into their starting position, without at the same time the tube being stretched in the region of the gripping elements and optionally oxygen being drawn into the tube.

The grip elements are preferably provided with a haptic improved surface design. The haptic-improving surface designs include grooved elevations, nubs or other surface profiling.

The size of the sidewall segments may vary depending on the purpose and specific dimensioning of the dosing. Thus, the side wall segments can each have about half the width of the side wall, so that the side folds with empty dispensing container in the interior of the same touch or almost touch. In such an embodiment, the filled, not yet emptied container has a substantially square cross-sectional area. If rectangular cross-sectional areas are desired, the gussets are usually in the interior thereof with the container completely emptied, but at a distance from one another.

Figure 24 is a plan view of an eighth embodiment of the present invention. FIG. 1 shows a perspective side view of the first exemplary embodiment of the present invention on the basis of a dosing container 1 designed as a tube-like packaging, which comprises two end walls 3 which connect opposite side walls 2 and side walls 3 connecting these side walls 2.

The side walls 2 are spaced and clamped in the region of a container head 4 by a container head plate 5, which can be seen in Figure 5 and from which a mouth portion 6 protrudes with an oval base, slightly convex, d. H. is convexly formed and connected via a ring 7, which is provided at right angles to the container plate 5, with this. The mouth section 6 is surmounted at its end and in the center by an outlet spout 8, which forms the removal opening.

At the opposite end of the container head 4 9, the side walls 2 are welded together and form a welding lug 10 from. At the point where the side walls 2 touch each other, ends the end side wall 3. The welding lug 10 may be stiffened and in any case imprint the region of the side walls 2 near the end 9 an intensely inwardly directed elastic deformation, through which the side walls 2 be placed against each other with their inner surface.

As FIG. 4 illustrates, the front side walls 3 are formed from segments 11, 12, which are connected to one another via a side fold 13 which is present within the envelope surface. In the embodiment shown in Figures 1 to 5, the gusset 13 extends to the end 9, to which the side walls 2 and the end side walls 3 are connected at a point, at least in the side view of Figure 4. In the region of the container head 4 is located itself from one of the side walls 2 bounding edge 14 initially outgoing gusset 15, the top 16 is aligned with the side fold 13. From the inclined surfaces of the gusset 15, the side wall segments 11 go off. The gusset 15 in the present case has a length corresponding to 0.09 of the length of the dosing container 1. This length of the dosing container 1 is measured from the distance from the container end 9 and the container plate 5. In other words, a lid 17 forming the lid of the dosing container (cf. 2, 7) is disregarded in determining the total length of the dosing tank. The length of the gusset may correspond to a length of 0.05 to 0.15, preferably 0.08 to 0.1 of the total length of the dosing container 1.

As can be seen, for example, from the illustration according to FIG. 4, the side walls 2 in the region of the removal opening 8 far end 9 of the dosing container 1 are essentially flat shape. As the side walls 2 approach the container head 4, this embodiment becomes increasingly convex.

The cap 17 forms a base for the upright dosing 1.

With increasing emptying of the dosing by pressing against each other of the opposite side walls 2 8 product contained in the container 1 product product is discharged in a conventional manner from the outlet spout. This is pasty or viscous product, such as tomato paste, mustard, toothpaste, creams. Here, the side wall segments lie 11 with its inner surface against the inside of the side walls 2. The outer surfaces of the opposite side wall segments 11, 12 pivot about the side fold 13 and lie against each other.

At the end of the conveying out, the state shown in FIG. 5 is reached, in which the mutually opposite side walls 2, with the inclusion of the inwardly folded side wall segments 11, rest against one another substantially without remaining material remaining. Only the region of the gusset 15 is easily set up and passes from this flat portion of the dosing container 1 to the container plate 5, where the side walls 2 are set up and spaced from each other by the container plate 5 extending at right angles thereto.

In the embodiment illustrated in FIGS. 1 to 7, only the container head plate 5 extending at right angles to the longitudinal extent of the dosing container 1 is formed as a shoulder element 24 by means of injection molding. In this original molding process, the front ends of the dosing container 1 substantially forming sheet material 25 are connected to the molten plastic of the shoulder element 24 and sealed with this. The ends of the film material 25 may be located in the plane extending at right angles to the longitudinal axis and thus in the region of the container head plate 5. It is also alternatively or additionally conceivable to shape the plastic material of the shoulder element 24 over a certain length of the film material 25 in overflowing fashion.

Figures 8 to 10 show an alternative embodiment in which the gusset 15 from the end 9 goes off. Also in this embodiment, the gusset 15 is struck inwards and hits with its tip 16, the side fold thirteenth In contrast to the previous embodiment, the welding lug 10 is formed in the second embodiment shown in Figures 8 to 10 much longer and penetrated by a bore 20 through which the dosing container 1 can be hung on a sales display provided with a rod. Instead of a circumferentially completely closed bore can also be provided a laterally opening tab. As a bore in this sense, any recording is understood that is suitable to keep the container 1 hanging.

Due to the arrangement and configuration of the gusset 15 in the second embodiment shown in Figures 8 to 10 results initially at the end 9 of the dosing from the point 21, where the side walls meet 2, in the side view of Figure 9 a gable roof-like configuration , wherein already the gusset 15 brings the two side walls 2 substantially to their maximum distance from each other.

As the side views according to Figures 4 and 9 illustrate, the side walls 2 are substantially planar, but may be slightly convex outwardly curved. Accordingly, in the side view between the edge 14 and the outermost point of the side wall 3 results in a certain distance. At least in the embodiment shown in Figures 1 to 7 corresponds to the curvature of the side walls 2 in the region of the container head 4 of the contour of the cap 17. The "tube" may also be rectangular or square in cross-section.

In the embodiment shown in Figures 8 to 10, the cap 17 is smaller than the container plate 5, which is slightly exposed in this embodiment, the outside and a cap rim 22 carries and is surmounted by this, which is connected via a film hinge 23 with the cap 17 is.

In the embodiment shown in Figures 1 to 7, the side walls are formed slightly convex in the region of the discharge opening 8 formed by the discharge opening, whereas these are formed at the end 9 almost flat. In the embodiment shown in Figures 8 to 10 results in a similar picture, but the curvature in the region of the removal opening is less predominant, but the convex curvature of the side walls 2 up to the welding lug 10, albeit only reduced, is maintained. FIGS. 11 to 15 show a third exemplary embodiment of a metering container according to the invention. Identical components are also identified here with the same reference numerals with respect to the previously discussed exemplary embodiments.

The exemplary embodiment shown in FIGS. 11 to 15 is characterized in particular by gripping elements 26, which are attached to the opposite side walls 2, close to the container head 4. The gripping elements 26 each extend parallel to the side walls 2 and are joined by means of injection molding formed the production of the shoulder element 24 and connected to the side walls 2. By means of these grip elements 26, the side walls 2 are reinforced and stiffened near the container head. As can be seen in particular from FIGS. 13 and 15, the grip element 26 in each case projects beyond the side wall 2 in the vertical direction, ie. transverse to the plane of the drawing according to FIG. 13. The gripping elements 26 are substantially plate-shaped and slightly curved in the circumferential direction of the dosing container 1 (see FIG. The repellent from the container head 4 end is formed semicircular. In the region of this end, the haptic-improving transverse ribs 27 are formed on the grip element 26, which projects beyond the otherwise smooth surface of the grip element 26 on the outside.

The container head end of the handle members 26 projects beyond a formed by the shoulder member 24 contact surface 28 for the cap 17. A provided with the curvature and extent of the handle member 26 on the cap 17 elevation 29 is located immediately adjacent to the head end of the handle member 26. The survey 29 is correspondingly provided offset in the region of the grip element 26 to the free end of the cap (see Figure 11). The elevation 29 and the grip element 26 may have mutually corresponding end surfaces, so that when the cap 17 is attached the grip elements 26 and then the side walls 2 are at least held in the region of the container head 4 in a predetermined orientation. In other words, the placement of the cap 17 on the dosing container 1 favors the alignment of the side walls 2.

As can further be seen from FIG. 15, the thickening forming the gripping element 26 also extends in the radial direction, ie. transverse to the longitudinal extension of the dosing container 1, whereby the injection molding of the shoulder element 24 and the connection of the shoulder element 24 with the film material 25 is simplified.

Figures 16 to 20 show a fourth embodiment of a metering container according to the invention. The same components are compared to the previous embodiments with the same reference numerals. In contrast to the embodiments discussed above, the embodiment according to FIGS. 16 to 20 has stiffening ribs 30 extending in the longitudinal direction of the container and projecting beyond the foil material 25 in the region of the side walls 2 and reinforcing the latter. The stiffening ribs 30 may be secured by means of ultrasonic welding on the film material 25. Alternatively, the stiffening ribs may be applied by overmolding onto the sheet material 25 together with the shoulder member 24 and bonded to the sheet material 25. In this case, for example, a gas pressure acting in the interior of the metering container 1 can keep it inflated with a relatively large volume, so that the stiffening ribs 30 after solidification promote a return of the shape of the metering container 1 to this starting position.

The stiffening ribs 30 extend over the entire length of the metering container 1 and open into a container reinforcement containing the bore 31, which extends transversely to the longitudinal direction of the container. Accordingly, the bore 20 is formed in a strength-enhanced region of the dosing container 1.

The gripping elements 26 are pivotable relative to the container head plate 5 about an axis A, in order to promote a pumping movement of the gripping elements 26, through which material from the container 1 is metered (see Figures 11, 13, 15). This axis is aligned with the abutment surface 28, i. the outer surface of the container head plate. 5

As can be seen from FIGS. 17 and 20, the stiffening ribs 30 end at the level of the cap 17. The cap 17 itself has no corresponding stiffening ribs 30. The stiffening ribs 30 are located at the edge of the side walls 2. Each of the side walls 2 has two stiffening ribs 30.

FIG. 21 illustrates an applicator which can be placed on the exemplary embodiment illustrated by FIGS. 11 to 15. In the present case, the applicator is identified by reference numeral 32 and serves for the planar application of the contents of the metering container. The applicator 32 comprises a delivery channel 33, which is surmounted by a spatula 34. Material discharged from the metering container 1 is accordingly supplied to the spatula 34 via the delivery channel 33.

The applicator 32 has a mounting ring 35 which is surmounted on its inner peripheral surface by a locking ring 36 which cooperates with a locking groove 37 formed by the shoulder element 24 in order to fix the applicator 32 to the dosing container 1. The previously discussed embodiment is merely an example of the variability allowed by the proposal according to the invention, in which the shoulder element 24 is first produced as a separate component by means of injection molding and connected to the film material. In injection molding, for example, functional elements or applicators can first be integrally formed on the shoulder element 24 via thin webs which form predetermined breaking points. After joining foil material 25 and shoulder element 24, these applicators or additional elements are first integrally formed on the dosing container 1. To use these additional elements can be solved by separating the predetermined breaking point and used in conjunction with the dosing 1.

FIGS. 22 and 23 show longitudinal sectional views through the container head 4 and illustrate, on the one hand, the shoulder element 24, which is hatched in FIGS. 22, 23 and forms a mounting flange 38 projecting toward the end 9, via which the connection between the film material 25 and the Shoulder element 24 takes place.

In the exemplary embodiment illustrated in FIG. 22, a valve element 39 is located in the outlet spout 8 with a slit valve 40 which closes the outlet opening and which is provided on a retaining ring 41 which is part of the valve element 39. This valve element 39 can be connected by injection molding with the shoulder element 24. Also conceivable is the injection-molding design of the valve element 39 and encapsulation of the valve element 39 with a second plastic component essentially forming the shoulder element 24. In this case, the valve element 39 is manufactured by two component injection molding.

In the embodiment shown in FIG. 23, the structure of which substantially corresponds to the structure according to FIG. 22, a valve flap element 42 closing off the removal opening is provided, which is formed during the injection molding of the shoulder element 24. The flap valve member 42 has a plurality of valve flaps which are relatively thin-walled connected to the shoulder member 24 and connected thereto. Therefore, the flapper member 42 can be relatively easily removed to make the contents of the dosing tank 1 accessible. An intact valve flap element 42 signals the user to the original state of the dosing container. 1

The embodiments shown in the figures all have dosing with rectangular in cross section envelope surface. The sidewall segments 11, 12 are directed inwardly and therefore lie within the envelope surface. Accordingly, the dosing container 1 is stored relatively compact side by side and vertically standing and offered for sale in a cardboard box. In the embodiments shown, the cap 17 forms a footprint for the upright dosing 1.

The material forming the container may be cardboard, composite material, laminate or foil, especially plastic film. In the case of composite material, in particular, a material is preferred whose inner layer is formed from a plastic film. As a result, the inner surfaces of the metering container 1 forming material can be welded together. The material should preferably have at least one plastic or cardboard layer, which gives the container a certain dimensional stability. The plastic material special provisions can be impressed, so that the dosing automatically merges with increasing emptying. In any case, the shape should be such that the container does not show any provision for removal of product from the container 1, through which air would be drawn into the container. The stiffness is then chosen so that the container with open removal opening and relief on the side walls 2 shows no corresponding provision.

FIG. 24 illustrates a relatively simply configured exemplary embodiment of a metering container 1 according to the invention. In this case as well, the predominant part of the container 1 is formed from folded film material 25, which is formed into a tube by a longitudinal weld seam and welded on its end side. The film material 25 has a welding lug 10 at the end. On the other side of the initially tubular film material 25 is a shoulder element in the form of a shoulder ring 43. This shoulder ring 43 is glued to the inner peripheral surface of the film material and has a base surface of the above-described container head 4 substantially corresponding base, so that the folded film material in the same way to the shoulder ring 43 can be connected, as has been previously described with reference to the previous embodiments. The shoulder ring 43 has a slight conically inwardly inclined mounting portion 44, on one side of the film material 25 is connected. On the opposite side of the attachment portion 44 is surmounted by any one of the outer peripheral surface contoured neck 45. The contouring on the outer peripheral surface of the nozzle 45 corresponds substantially to the inner circumferential surface of a retaining ring 46 of an injection-molded end cap 47 provided contouring. In this case, the end cap 47 merely represents an example of an end-side closure of the metering container 1. Depending on the specific Demands, other, preferably injection-molded elements can be attached to the nozzle 45. The attachment is in this case preferably via wringing of the closure element.
