Container and container lock

The invention shall look check on container with the associated fasteners and more particularly to a container of the Ausfiihrungsart having an outer shell or Au3enbehälter gaaz ₅ BT or part facing © AU8 a rigid material such BIeQh ₉ ■ 3talilfel, @ consists eh ₉ fibrous material, plywood © the äergl " , 's © - like a thin-walled inner jacket or lining ₉ which is entirely made of a flexible material, goB, a thermoplastic material such as polyethylene or the like, and has at least one neck section protrudes through an opening in the outer container or the associated cover ο ■

Further, to be provided on the neck of a liquid tight seal to daee _s Einsickere won liquid into the Auß'enb he ehält \ m & along the outside & et. To prevent lining.

It has already been proposed to line one

Tv to such a container with an inner or = externally threaded neck, and to attach a threaded plug or a Sehraubkappe on the neck ₅ of which material is preferably that of the liner is similar to the container to versohlie-transmitter and seal.

Such a neck must be sufficiently rigid so that it can withstand the forces occurring in the sewing passages, and to enable a sufficiently high specific pressure to be applied to the threading surfaces. " When the inner shell in the sweep of the blow molded _9, it is erforder = IiOh _5, a Butsen to fer? I'endea ₅ whose wall thickness _f is sufficient for the neck-forming portion of the tool fill "With thick-walled liners or self-supporting sheaths of tliermoplastisehem material prepares this usually no problem, but results in thin wall linings the need _for a thick Butaen inflate ₉ to a very high Aufblaseverhältnis and thus to poor material distribution and to a greater risk of the occurrence of internal tensions "

In addition, in such constructions, the Haehteil, that it sohem in the manufacture of the neck from thermoplastic Material and when using a similar material for the G-thread plug or the screw cap also makes it difficult to produce the desired parts in the manufacture of these parts Dimensions to be observed.

Another disadvantage is that they are very different ehen sand thickness. that lead to undesirable accumulations of stress on the Foot of the neck can lead? furthermore, the thick-walled one requires

EaIs eiaa longer cooling time than the thin wall of the actual container? whereby the production speed increases = - loan is reduced.

The invention now provides a container and a container TOr ₈ which can be manufactured at a remarkably low cost.

Further Torgesßhlagenj has been to close the lining or 'the neck by applying heat or absudiGhtea ₉ but it is in this case erforderlieh "cut the TerschliiB η when the container is to be emptied" This is the re-closing a partially geleer -tan containers, er-sshwerts, - if not made impossible, tm.d also do not allow such containers to be used as returnable containers.

An object of the invention is au verm ^ identical _P and in view of this and other objects ₉ these difficulties, the invention provides a container of the above indicated kici ¥ or _s at aera the Tandstärke of the neck portion of the liner made of a flexible materiel in the order of the found strength of the actual container lies "and in which the free end of the neck is connected to a jacket section of a larger diameter than the neck

In this case, one or other kein® Grewindegänge particularly F'ormsa sub closing or sealing the container -Next = © advantages are ₉ that check the shrinkage of the Hsiistel-Xung ausreiolieD.d beherrseliQia IaQt ₉ - and that no uneven on one wall thickness iizrücksuführenaen Sohrampfspanaimgsii occur »In the so far known constructions ftia.r®E, such shrinkage stresses as so-called stress cracks.

In known Kcnstriiktloiaeas, - with ctenen a threaded neck with the lining consists of one piece ₉ the neck is held in the axial direction by a ring; In most cases this ring is screwed onto the neck of the lining, and it does not produce any liquid-tight "■ YersölilnSj se äaS liquid in the outer container in the space swiseken- this and the inner jacket can seep" This is particularly undesirable. » if it is about a corrosive liquid Isaadelt and the liquid can pour overflowing onto the upper part of the outer container during the symphony. This difficulty, too, is eliminated by the Irfindiifts ₉ because "no holder is required."

Since the wall thickness of the container according to the invention Neck of the lining is of the same order of magnitude as that of the actual lining, one can remove the shark. ? j @ der directly from a thin "Bsrteen or from it

In this way, an absolutely liquid-tight closure can be used, which also offers protection against unauthorized handling.

Further Sinaelheiten and gate parts of the invention result sieve, from the following description of several embodiments on the basis of the drawings «.

Fig. 1 is one partially drawn as a longitudinal section Side view of an embodiment of an inventive -.

- Fig »2 is similar to fig = I ₉ but shows a" different form of training of a BetealterTersehlusses near the invention »

ätEäi3 Pig »1 UfflfaSt the inventive container, which is only partially shown, consists of an outer casing or outer packaging 11, cie gsns or partly of a rigid material - in the present case of sheet steel -» However, the outer casing can also be made of another sheet metal material »hardboard« Plywood can be made of some other suitable rigid material. Furthermore, the container comprises a thin-walled inner jacket or a lining 12 made of a flexible oil

thermoplastic material such as polyethylene uai the like.

The lining 12 has a neck 13 which protrudes through an opening of the outer container 11 or its cover and has a wall thickness _P which is essentially the same as that of its own. The lining 12 is at least as large as the wall thickness the liner is "the free ends of the neck 13 is provided with a sewing projecting below Mantelab · = · cut. 14 joined by gröSereia diameter than the neck 13 ₉ and the skirt portion 'encloses a rigid annular body which, for its part, around the opening of Au3enbehälters or of the associated lid extends? Naeh in the embodiment of FIG ₀ 1 of this ring-shaped member is formed by the free end of a neck 15 ₉ of the wall of the outer container or the Deckais of one piece consists ₉ -and its free bath © "rolled at 1β or umöräelt.

The lapel section 14 can be formed by the free end of the sleeve 13, which is folded over on itself for this purpose; alternatively, the casing section can be molded onto the neck of the liner while it is being bitten or shaped.

Bar container is made with the help of a resilient lid 1? ■ f developed ^ which consists of a similar material as the lining 12 _S S ₀ B ₀ made of polyethylene.? so that the flexibility of the material made it possible to push the cover over the bead 16 along with the attachment and removal. In the preferred embodiment shown here, the resilient cover 12 has the same wall thickness as the lining 12 and its

The right-hand part of Fig. 1 shows the jacket of the outer cap in its final position. In this way, the thin layer of material of the neck of the liner and of the "resilient lid" see the rigid outer cap 18 made of metal and the rigid , made of metal = the beaded edge 16 of the outer neck crimped or clamped. » so that a liquid-tight closure results ₉ which offers a safeguard against unauthorized opening.

If the container tenutat again solj. you can attach a new metal cap; which, in particular, causes low costs compared to "the entire container.,

The embodiment shown in FIG. 2 is essentially "similar to that described above with reference to FIG. 1," which has a · = The only difference is that the resilient cover 17 is a downwardly indented middle piece possesses ^ and that a "cup-shaped support part 20 made of metal in the recess formed in this way is inserted »The cup-shaped support part has the task of Bead 16 and the outer neck 15 during flanging Rolling down of the jacket 19 absustütsenj, and also the support part improves the seal, because the resilient Deekel 1? and the neck 13 »14 of the liner become longitudinally" two circumferential zones.
