according to the line I - I of Figure 1 1.

The tube packaging, generally designated 1 in FIGS. 1-7, essentially consists of a metallic tube 2

Material, preferably of aluminum or an aluminum alloy. The tube 2 is formed on its tube shoulder 4, which is made in one piece with the remaining tube body 3, with a tube nipple or mouth piece 6 forming an opening 5.1. The mouth piece 6 is at his

Outer surface on a subsequent to the opening 5.1 axial

Partial length 6.1 profiled, i. formed in the illustrated embodiment with a plurality of in the axial direction of the mouth piece 6 extending projections and grooves located therebetween and has at the transition to the tube shoulder 4 an annular groove 6.2. in the

~ ⁾ original state of the tube packaging 1 is the opening 5.1 with a pierceable produced in one piece with the mouthpiece 6

Membrane 7 closed.

8 with a tube flange is referred to, which is made as a molded part made of plastic and with the tube assembly 1 assembled on the

Mündungsstück 6 is secured against rotation by bouncing or latching, by the fact that 8 inside projections or projections 10 are formed in a sleeve opening 9 in the region of a Flanschendes 8.1 of the tube flange, which engage in the annular groove 6.2 by latching, and also in the sleeve opening 9 web-like, parallel to the axis of the tube flange 8 extending projections 1 1 are formed, which engage in the profiling of the partial length 6.1 and in the local grooves. In the mounted state, the tube flange 8 engages with a provided in the region of the flange end 8.2 and into the sleeve opening 9 in annular portion 12 the muzzle 6 at its end facing away from the tube shoulder 4 such that the actual Tube opening 5 on the tube body 3 side facing away from the

Membrane 7 substantially from the local open end of the

Sleeve opening 9 is formed and in any case, however, a tight seal between the mouthpiece 6 and the tube flange 8 is made.

With 1 3 is also a manufactured as a molded plastic

Closure cap referred to, which has an outer diameter in the illustrated embodiment, which is equal to or about the same

Diameter is that the tube body 3 has in the region of its tube shoulder 4. In order to achieve a simplified handling or an elderly-friendly handling of the tube packaging 1 with regard to the removal of the closure cap 1 3 from the tube 2 and with regard to the reapplication of the closure cap 13 to the tube 2, the locking between the closure cap 1 3 and the tube 2 or the tube flange 8 bayonet-like, inter alia, so that the up and turning of the cap 1 3 with a rotational movement of 180 °, but in fact can be done with a rotational movement less than 180 °, that the placement of the cap 1 3 on the tube or to the tube flange 8 easily and without compliance with a specific rotational position of the cap 1 3 with respect to the tube flange 8 is possible, and that when closing the tube 2 with the cap 13 a tactile end stop and a tactile and audible latching takes place.

In order to achieve this, the tube flange 8 is formed on its peripheral surface with two bayonet depressions 14 each causing the bayonet locking, which are shown particularly clearly in the development of FIG. 7 and in the circumferential direction (X axis of FIG. 7) of the tube flange 8 directly connect each other, each bayonet recess 14 forms a first portion 14.1, which faces away from the circumference of the tube flange 8, but also to the end of the tube 4 8.2 remote from the tube shoulder

Tube flange 8 to form a local insertion opening 1 5 is open. Of the Inlet opening 1 5 opposite each section 14, 1 axially (in the direction of the flange axis FA or in the direction of the Y-axis of Figure 7) delimited by an insertion be 1 6, of the top in the figure 7 flange 8.2 towards the in this figure lower flange 8.1 runs. Each bayonet recess 14 is further formed with a portion 14.2 which is only radially, that is open at the periphery of the tube flange 8, in the axial direction, ie in the direction of the flange axis FA or in the direction of the Y-axis and at the portion 14.1 removed lying end but is closed. The respective section 4.2, which is attached to the

Section 14.1 at which the flange end 8.1 closer area of the insertion be followed 1 6, is for Erzseiung a latching the

Closure cap 1 3 when closing the tube 2, in particular also to achieve a clearly palpable and audible latching formed so that this section at the transition to the section 14.1 forms a first portion which in the axial direction of the sleeve-like

Tube flange 8 has a reduced width, and that adjoins this first section a second section, which has an enlarged width in the axial direction of the tube flange 8. This enlarged width is achieved in that the second section is extended in the axial direction to the flange end 8.2 out. As a result, at the transition between the two sections 14.1 and 14.2 in section 14.2 a standing in the section 14.2 locking lug 1 7 with inclined surfaces 1 7.1 and 1 7.2 formed. As the figure 7 shows weiterhi, the two bayonet wells 14 are designed so that there, where the insertion opening 1 5 of a bayonet recess 4 ends immediately, ie seamlessly the insertion bevel 6 of the other bayonet recess 14 connects and thereby the section 14.2 of each Bajo ett- recess 14 below the insertion be 1 6 of the other bayonet recess 14 is located. In addition to the bayonet depressions 14, the sleeve-like tube flange 8 is at least at one the Flanschende 8.2 axially adjoining portion of the outer surface slightly bevelled, in such a way that the diameter or radius of the outer surface decreases in this area in the direction of the flange 8.2. Both bayonet wells 14 are identical.

The cap 1 3 is in the illustrated embodiment

double-walled, with an outer, the axis VA of the cap concentrically enclosing wall 18 which forms the gripping surface for handling the cap 13 on its outer surface and is profiled or wavy to improve the grip or handling. Is the cap 1 3 with an inner

executed circular-cylindrical wall 19 which also surrounds the cap axis VA concentric and whose inner diameter is equal to or approximately equal to the outer diameter of the tube flange 8, so that the closure cap 1 3 with the W'andabschnitt 9 fits on the

Tube flange 8 can be placed. The closure cap 13 is further formed with a curved bottom 20 over which u.a. the walls 18 and 19 are connected to the one-piece cap 13. The bottom 20 is formed on its bottom wall facing away from the inner wall 19 with a circular recess 21 arranged coaxially with the axis VA, in which a mandrel 22 arranged with its axis coaxial with the axis VA is provided, with which the original is closed when first opened Tubular packaging 1 which serves as tamper-evident membrane 7 can be pierced. The bottom of the recess 21 is a in the illustrated

Plan embodiment and perpendicular to the axis VA of the cap 3 oriented wall 23 is formed, which also from the inner

Wall 1 enclosed space Zy! Inderraum 27 in the region of the recess 21 and, at the end of the verses lusskappenboden 20 end facing. In the cylinder chamber, the wall 23 with a

molded, the axis VA of the cap 1 3 concentric enclosing annular projection 23 is made, the

Outer diameter is equal to or slightly larger than the cross section of the sleeve opening 9 or tube opening 5 in the region of the flange end 8.2. When closed with the cap 1 3 tube 2, the projection 24 extends into the sleeve opening 9 in the region of the flange end 8.2 and thereby seals the tube opening 5 even after the piercing of the membrane 7 from. In order to achieve this tight closure in a particularly optimal manner, the annular projection 24 are beveled, for example, on its outer surface and / or the tube opening on its inner surface frustoconical.

On the inner surface of the wall portion 19 are two pin-like

Formed projections 25 which are part of the bayonet-type locking between the closure cap 1 3 and the tube 2 and which in each case based on the axis VA of the closure cap 1 3 radially from the

Stand out inside surface of the wall 19. Relative to the axis VA, the two projections 24 are further provided offset by 180 ° from each other, in the same axial distance from the wall 23. In the wall 23 each projection 25 associated with a window 26 is provided, which in the following will be described in more detail Way in molding the projections 25 by the molding or

Injection mold is created. The windows 26 are located outside of the sealing area of the closure cap 13 formed by the annular projection 24, so that they do not impair a tight closing, in particular a tight reclosing of the tube 2. It is understood that the cap 1 3 is made in one piece with all elements made of plastic.

When reclosing the opened tube 2, the closure cap 1 3 with its closure cap underside, ie with the open end of the wall 19 and the cylinder space 27 on the tube flange. 8 attached, wherein the two projections 25 by one

Insertion opening 1 5 come against the insertion bevel 1 6 a bayonet recess 14 in the region of section 14.1 to the plant. By slight axial pressing of the cap 1 3 against the tube 2 and by turning the Versch Susskappe 1 3, the projections 25 then slide along the insertion bevels 1 6 in the respective section 14.2, in which they engage behind the locking lugs 1 7, so that the Cap 1 3 at the tube flange 8 and thus held on the tube 2 while closing the tube opening 5. By a certain inherent elasticity, which has the closure cap 1 3 in particular by the curved formation of the closure cap bottom 20 and by the arrangement of the annular projection 24 on the final wall 21 of the recess 21 is ensured that even after the latching, i. After passing the projections 25 on the respective latching lug 1 7 of the annular projection 24 still with sufficient contact force against the tube opening 5 and against the sleeve opening 9 in the region of the flange 8.2 is present A slight overcoming of the respective locking lug 1 7, i. a shallow passing of the projection 25 on the respective latching lug 1 7 is achieved in that it is chamfered at its adjoining the portion 14.1 region at 1 .1 the course of the insertion bevel 1 6 accordingly. For a simple overcoming of the respective locking lug 1 7, i. for a simple passing of the projections 25 on the respective locking lug this is ebenfal ls bevelled at its the portion 14.1 remote side at 1 7.2. Due to the special design of the bayonet depressions 14, it is ensured that when the slip cap 1 3 is placed in any arbitrary rotational position with respect to the tube 2, it is inevitable for everyone

Projection 25 by an insertion 1 5 against a chamfer 1 6 comes to rest, at any point in the section 14.1, so that then by turning the cap 1 3 relative to the tube 2, the closing of the tube 2 can be effected without when putting on the closure cap 13 on the tube 2 a predetermined Winkeliesieilung the closure cap 1 3 must be maintained with respect to the tube 2.

The cross-section of the circular cylindrical recess 21 is equal to or slightly larger than the outer diameter of the tube flange 8, so that by placing the cap 1 3 with the recess 21 on the tube flange 8, the membrane 7 can be pierced when first opening the tube package 1 with the mandrel 22. As FIG. 7 also shows in particular, the section 14.1 and thus the insertion opening 15 and the insertion slope 16 extend in FIG

Circumferential direction (X-axis) of the tube flange 8 over the much larger portion of each bayonet recess 14, i. the length or angular range over which the respective section 4.2 in the circumferential direction of

Tube flange 8 extends, is many times smaller than that

The angular range over which the respective section extends 14.2, for example, only 20% to 30% of the angular range over which the insertion opening 15 extends, preferably in about 25% of

Angular region of the insertion opening 5.

In the region of each bayonet recess 14, the circumferential or circumferential surface of the tube flange 8 is a circular cylindrical surface. The insertion bevel 16 extends helically with respect to the axis FA and forms a surface which is oriented perpendicular to this circular cylindrical surface. In the region of section 14.2, the insertion bevel 16 merges into an area 1 6.1, which has no pitch with respect to the axis FA of the tube flange 8, ie runs perpendicular to the axis and to the lateral surface of the tube flange 8. To puncture the membrane 7 at the first opening of the

To facilitate tube packaging 8, it is possible, in the recess 21 and on the inner surface of this recess bounding part-cylindrical wall corresponding to the projections 25

Provide projections 25a {Figure 6), again relative to the axis VA of the cap 1 3 offset by 180 ° from each other and at the same axial distance from the wall 23, wherein each projection 25a is associated with a caused by the molding window 26a. The piercing of the membrane 7 is then carried out by placing the

Cap 1 3 with the recess 21 on the tube flange 8, wherein the projections 25 a through the Einführöffnu conditions 1 5 against each insertion chamfer 1 6 come to rest and then when turning the

Lock cap 1 3 relative to the tube 2 on the chamfers 1 6 along sliding behind the locking lugs 1 7 engage. The membrane 7 is pierced by the mandrel 22, which is signaled to the user by the tactile and / or audible clicks.

It was assumed above that the inner cross section of the wall 1 9 is equal to the outer cross section of the tube flange 8. In order to facilitate the placement of the cap 1 3 when reclosing the tube 2, the enclosed by the wall 1 cylinder space 27 of the cap 1 3 but at its open end an expanding cross-section formed by a section 1 9.1 of the wall 1 9 and is larger than the outer cross section of the tube flange 8 in the region of the bayonet recesses 14. This expanded cross section of the

Cyl inderraumes 27 accordingly, the tube flange 8 is provided between the end of the flange 8.1 and the bayonet wells 14 on its outer surface with a ring-like projection 28 so that when attached to the tube 2 cap 3, the wall 1 9 with its section 1 9.1 projection 28, otherwise but the tube flange 8 outside the

Projection 28 fits around. In FIGS. 8-10, 1 a is a tube packaging that differs from the tube packaging 1 essentially only in that the tube 2 a is made of plastic, namely with the tube body 3 a and the tube sealer 4 a, which in turn is integral with the tube the tube opening 5a and the tube-side part of the bayonet tube are formed forming tube nipple or tube flange 8a. , With regard to the bayonet recesses 14 and the recesses formed by these recesses

Functional elements, in particular insertion 1 5 and insertion bevels 1 6, the tube flange 8a is formed identical to the tube flange 8, so that the above statements, in particular to the bayonet locking means formed by the Bajoneit- Verliefungen 14 and the resulting advantageous handling also apply to the tube flange 8a ,

As a tamper-evident seal or closure, the tube flange 8a is provided in the region of the tube opening 5a with a closure element 30 closing the tube opening. The latter is about an annular

Predetermined breaking section with reduced wall thickness integral with the

Tube flange 8a shaped, and plate-shaped or substantially plate-shaped with a star-like peripheral surface

The tube package 1 a further comprises a closure cap 1 3a, which differs from the cap 1 3 only in that the recess 21 a corresponding recess 21 a is adapted in its cross-sectional shape to the cross-sectional shape or to the outer contour of the closing element 30, so that at first opening of the tube packaging 1 a, the cap removed from this packaging 1 3a with the recess 21 a placed on the closure member 30 and the latter can then be removed or rotated by turning the cap relative to tube 2a. The cross section of the recess 21 a is preferably so dimensioned that the closure 30 is clamped in the recess 21 a and thus remains after twisting in the recess 21 a.

The production of the Verschiusskappen 1 3 and 1 3a is done in one

multi-part injection mold whose tool parts and / or slide after the injection molding of the respective cap 1 3 or 1 3a for the removal or removal of the produced cap 1 3 or 1 3a are moved only in the cap axis VA, so as simple as possible and To achieve reliable construction of the injection mold. To this example, the on the inner surface of the

circular shaped wall 19 formed and from this wall with respect to the axis VA radially projecting into the cylinder space 27 protruding projections 25 and in particular to enable the demoulding of this area forming part of the injection mold is formed as shown in Figures 1 1 and 12 is shown very schematically. The injection molding tool exists there i.a. from a circular cylindrical on its outer surface formed core 31 and two sliders 32, each with a closed injection mold on the Ümfangsf the core 31 provided and parallel to the axis KA of the core 31 extending and offset by 180 ° about the axis KA groove-shaped Recess 33 is arranged The slide 32 and recesses 33 are shaped so that the arranged in each case a recess 33 slide 32 fits in the recesses 33rd

are added and complement with their outer circular cylindrical curved surface as seamless as possible, the circular lateral surface of the core 31 in the region of the recesses 33. Each recess 33, open to the periphery of the core 31, is closed at one end at 33.1, where it is connected to a e.g. Semicircular extension provided with a closed injection mold with a

corresponding recess, which abuts against the end 33.1 End of the slider 32 is provided to supplement the respective projection 25 forming space 35.

After the injection molding of the respective closure cap 13 or 1 3a is then the demolding of this cap in spite of the projections 25 by axially moving apart of the core 31 and the slider 32 in the core axis KA possible. Similarly, the molding of the

For this purpose, according to FIG. 11, the two slides 32 are part of a further core 36, which is arranged coaxially with the core 31 at least when the injection mold is closed, ie. the two slides 32 project axially beyond an end face of the further core 36. The core 36, the peripheral surface of which forms the inner surface of the recess 21, is again formed on this peripheral surface, for example, in the form of a circular cylinder in relation to the axis KA. In two about the axis KA offset by 180 ° and are extending in axiai

groove-shaped recesses 37, in turn, at least when the injection mold is closed, a slider 38 is received, which in this case the circular cylindrical peripheral surface of the core 36 in the region of

Recesses 37 continues. The recesses 37 are in turn open to the periphery of the core 36 and have a closed end, which is formed during the injection molding of the end face 31 .1 of the core 31. Against this end face 31 .1 are the slide 38 with its end and form there with recesses, which complement with corresponding recesses on the end face 31 .1 each have a mold space 39 for forming a pin-like projection 25 a. The demolding is in turn only possible by axially moving the cores 31, 36 and the slider 38 in the direction of the axis KA. The slides 32 and associated recesses 33 and the slide 38 and their associated recesses 37 each form slide and recess pairs in which the recesses 33 and 37 and their slides 32 and 38 offset in the manner described above by 180 ° about the axis KA are and in turn at the illustrated Embodiment are provided offset by 90 ° about the axis KA against each other.

The described embodiment of an injection molding tool having at least one core 31, 36, the circumferential axis or circumferential surface enclosing the core axis KA forms an inner surface of a molding, and with at least one slide 32 and 38, which in injection molding between a

Slider surface and a closed end of the respective recess 33 and 37 forms a mold space 34 and 39 for forming a projecting over the inner surface of the molding projection is, according to one of the invention underlying knowledge not only for the production of the Verschiusskappen 13 and 13a, but genereil suitable for the production of appropriate molded or injection molded plastic parts. The invention has been described above with reference to an exemplary embodiment. It is understood that numerous changes as well

Modifications are possible without thereby departing from the inventive concept underlying the invention.
