The in the figures generally with 1 designated tube packaging consists essentially of the example of plastic, but preferably of metal, for. B. made of aluminum or aluminum alloy tube body 2 as well as from an adapter three , an applicator 4 and one cap 5 , which are each, for example, molded plastic parts.

The tube body is integral with a tube surrounding the tube interior 6 , with one at one end of the tube sheath 6 subsequent tube shoulder 7 and with one at the tube shoulder 7 provided tube body nipple 8th educated. The tube body nipple 8th forms a tube body opening 9 , in the original or delivery condition by a likewise integral with the tube body 2 manufactured metallic pierceable membrane 10 is closed.

The essentially sleeve-like open-ended adapter three is with his in the 1 Lower end by bouncing or by locking captive on the tube body nipple 8th held against rotation. For this purpose, the tube body nipple 8th on its peripheral surface with a knurling 11 and with a locking groove 12 between this knurling 11 and the tube shoulder 7 educated.

The of the tube jacket 6 and the tube shoulder 7 limited tube body interior is after filling the tube body 2 with the respective product at the tube shoulder 7 opposite side in a suitable manner, for example by crimping and / or welding or otherwise closed.

The 4 and 5 show the adapter three closer in detail. This is formed substantially sleeve-like with a through opening, with a section 13 with larger, circular-cylindrical inner and outer diameter and with an axis equal to the section 13 subsequent circular cylindrical section 14 with reduced inner and outer diameter, wherein the inner diameter of the section 14 or its opening 14.1 equal to or about equal to the diameter of the circular cylindrical tube opening 9 are. At the outer or outer surface of the section 13 is the adapter three in one piece with the axis TA of the tube packaging 1 and hence the axis of the adapter three concentrically enclosing annular projection or collar 15 provided and in the direction of the section 14 axially afterwards with an external thread 16 , With the the section 14 remote end ahead is the adapter three on the tube body nipple 8th aufgeplellt, in such a way that the tube body nipple 8th from the section 13 of the adapter three is enclosed and on the inner surface of the adapter three or the section 13 formed bead-like locking projections 17 in the locking groove 12 and on the inner surface of the section 13 molded webs 18 in the knurling 11 intervene, so the adapter three captive and also torsion-proof on the tube body 2 or tube body nipple 8th is held.

The applicator 4 essentially forms a cap-like or screw-cap-like section 19 , follow this section 20 , as well as a subsequent section 21 , The sections 19 - 20 are provided coaxially adjacent to each other, with the sections 19 and 20 are executed in each case substantially circular cylindrical on its outer surface, the section 19 however, with a much larger outer diameter than the section 20 , The section 21 is formed on its outer surface tapering towards the free end.

In the section 19 is the applicator 4 with a substantially circular cylindrical circumferential or cap wall 22 in one of the wall 22 limited interior 23 one over a cap floor 24 upstanding sleeve-like projection or mandrel 25 surrounds at a distance. On the inner surface of the cap wall 22 is starting from the the interior 23 facing side of the cap bottom 24 an internal thread 26 provided, which for interaction with the external thread 16 is trained. From the internal thread 26 is spaced at the free end of the section 19 or in the area of the opening there into the interior 23 extending, the axis of the applicator 4 and with mounted tube packaging 1 also the axis of the adapter three and the tube body nipple 8th annularly surrounding projection 27 intended.

In the applicator 4 is a channel 28 formed at the free end of the mandrel 25 as well as at the opposite end of the applicator, ie at the free end of the section 21 is open and forms an application opening there.

On its outer surface is the thorn 25 circular cylindrical, but in any case with an outer diameter, the inner diameter of the opening 14.1 as well as the inner diameter of the tube body opening 9 corresponds so that an outwardly dense transition between the tube interior and the channel 28 in particular also exists when the thorn 25 in the manner described in more detail below in the tube body opening 9 after piercing the membrane 10 is introduced.

When the tube packaging is assembled and in its original state 1 ie, in the state where the tube package filled with the product 1 delivered, stored and / or delivered to the respective customer or customer is the applicator 4 with his section 19 such on the tube body 2 attached adapter three put on that the lead 27 the covenant 15 engages behind and thereby the applicator 4 also captive on the tube body 2 or on the local adapter three is held. Furthermore, the internal thread 23 in this Original or delivery state of the tube packaging in the direction of the tube axis TA laterally from the external thread 16 arranged so that the threads of these threads are supported against each other, but not yet engaged. This is the applicator 4 on the adapter three against an axial displacement in the direction of the tube body 2 secured. The free end of the thorn 25 and a blade-like projection formed at this free end 25.1 are in this original or delivery state corresponding first position of the applicator 4 from the membrane 10 spaced, but in the opening 14.1 of the adapter three recorded, so that thereby an additional support of the applicator 4 on the adapter three results, ie the applicator 4 Also in the original or delivery state so "wobble-free" on the adapter three and thus on the tube packaging 1 is provided.

To use the tube contents, turn the applicator 4 around the axis TA the internal thread 26 increasingly on the external thread 16 unscrewed, causing the applicator 4 axially in the direction of the tube body nipple 8th is moved and thereby the membrane 10 finally with the thorn 25 perforated or pierced. Into the tube body opening 9 tightly inserted thorn 25 (second position of the applicator corresponding to the state of use 4 ) and with the cap removed 5 can then the product from the interior of the tube body 2 be applied by pressing or squeezing this tube body at the application opening. The thorn 25 lies with a molded on the mandrel outer surface cone-shaped portion ( 25.2 of the 11 ) against the example conically beveled inner edge of the tube body opening 9 at.

On the outer surface of the section 19 is the applicator 4 provided with a corrugation, which forms a handling surface facilitating the handling. Furthermore, the applicator 4 on the outer surface of the section 20 with an external thread 29 provided on which the cap designed as a screw cap 5 with an internal thread 30 can be screwed on. The external thread 29 forms at its the section 19 adjacent end a stop 31 , against the cap screwed on 5 one end of the internal thread 30 is applied, whereby a too firm and re-loosening complicating screwing or jamming the cap 5 on the applicator 4 is avoided, especially even if the cap 5 or the knurled outer surface of this cap as a handle for rotating the applicator 4 around the axis TA at the first opening of the tube packaging 1 or when piercing the membrane 10 is used.

The assembly of the tube packaging 1 takes place, for example, in the form that in a previous assembly step or in a previous assembly line respectively from the adapter three , the applicator 4 and the cap 5 existing applicator unit is preassembled, so that each applicator unit then by pushing or bouncing on a tube body 2 or on the local tube body nipple 8th can be mounted, with the spike 25 after mounting with axial distance from the membrane 10 located but fitting and sealed in the opening 14.1 of the section 14 extends. In this state, the provided on its outer surface with the necessary equipment packaging 1 filled and sealed by the user with the product.

In every possible position of the applicator 4 , Especially in the first and second position of the applicator 4 is the thorn 25 sealed in the opening 14.1 taken so that remains within the applicator of the space occupied by the product even then sealed to the outside, if after the first opening of the tube packaging 1 or after piercing the membrane 10 with the thorn 25 the applicator 4 from the second position where the spike 25 sealed by the tube body opening 9 extends into the interior of the tube body, is moved by the user consciously or unconsciously by turning back to the first position, in which the free end of the mandrel 25 from the tube body opening 8th is spaced.

The 8th - 11 show a tube packaging 1a that differ from the tube packaging 1 by a modified design of the adapter 3a or the applicator 4a different.

The in the 9 and 10 in an individual representation reproduced adapters 3a is different from the adapter three only by the fact that the adapter three at the section 13 integral with a plurality of over the circumference of this section wegstehende latching means 33 , In the illustrated embodiment locking lugs is formed. The applicator 4a is different from the applicator 4 only by the fact that at the bead-like projection 27 several locking means 34 , Recesses are formed in the illustrated embodiment, which cooperate with the locking lugs such that in the position of use of the applicator 4a ie after piercing the tube opening 9 originally occluding membrane 10 the locking lugs are each received in a recess, in such a way that a turning back of the applicator 4a in its initial position before piercing the membrane 10 is no longer possible.

By locking the locking means 33 in the locking devices 34 In the illustrated embodiment, recesses is thus prevented that the tight connection between the mandrel 25 or the channel 28 and the tube body opening 9 , in particular by the concern of the conical section 25.2 (Sealing cone) against the inner edge of the tube body opening 9 is produced, is lost by a possible incorrect operation and thereby tube contents in the interior of the adapter 3a or in the interior 23 of the applicator 4a arrives.

The invention has been described above by means of an embodiment. It is understood that numerous changes and modifications are possible without thereby departing from the inventive concept underlying the invention.
