Definitions

  • Container in particular for liquids
  • the invention relates to a container, in particular for liquids according to the preamble of claim 1.
  • a container according to the preamble of claim 1 is known from DE 39 42 319 C2. It comprises a basic body produced from a multilayer cardboard composite material, which is connected in particular by means of a heat-sealing connection to a closure body which forms a head part of the container. In a connection region between the main body and the closure body, the closure body has radially encircling sealing lips which, for a particularly good or tight connection between the body
  • Main body and the closure body should provide. It is essential that the main body engages around the closure body in the connecting region radially from the outside, such that the one end face of the main body facing the closure body is unprotected against the entry of media or mechanical loads. Therefore, it is known from DE 39 42 319 C2 also known to cover the addressed end face of the body by means of an additional annular body and thereby protect.
  • the disadvantage here is that the attachment of the protective body means an additional step and thus increases the cost of manufacturing the container.
  • the invention has the object, a container in particular for liquids according to the preamble of claim 1 such that at the lowest possible
  • Locking body protrudes to form an annular receiving pocket, and that in the receiving pocket, an end-side end portion of the base body is arranged.
  • the invention thus sees, in contrast to the prior art, a
  • Closure body before in which a protective element designed as a sealing lip is already integrally formed on the closure body and thus does not require a separate manufacturing or assembly process during production to protect the frontal region of the body.
  • a particularly advantageous production of the container can be achieved if the sealing lip protrudes at an oblique angle with respect to a longitudinal axis of the sleeve-shaped closure body, so that in the insertion direction of the main body into the receiving pocket results in a reduced cross-section, and if the opening width of the sealing lip in an opening area is greater than the outer diameter of the body. This allows a particularly simple assembly between the closure body and the
  • a mechanically sufficiently good protection of the body at the same time manufacturing technically advantageous manufacture of the closure body is made possible when the wall thickness of the closure body between 0.5mm and 1, 0mm, in particular 0.7mm, and if the wall thickness of the sealing lip between its Anformung and its free end decreasing, with the average wall thickness is 0.2mm.
  • connection region between the closure body and the base body can also be particularly easily and tightly manufactured with respect to the entrance of media when the cross section of the base body and the
  • Closure body is formed in the connecting region at least approximately circular.
  • a connection between the base body and the closure body is preferred by an ultrasonic welding connection.
  • Such a compound has the advantage that it can be implemented relatively easily in terms of mass production and, in particular, that no additives, such as glue, etc., are required, so that the production is furthermore particularly easy to carry out.
  • the closure body and the base body at least in the area of the ultrasonic welding connection on sides facing each other from the same kind of plastics, in particular HDPE or LDPE consist.
  • closure body in the overlapping or connecting region with the base body has at least one, preferably a plurality of axially spaced, radially extending elevations.
  • Receiving pocket decreases.
  • a container according to the invention for the aseptic packaging of foods. It is by the
  • inventive construction of the container in particular the access of bacteria, germs or the like in the container interior safely avoided.
  • Fig. 1 is a partially sectioned side view of a container according to the invention.
  • FIG. 3 shows a detail of the container according to FIG. 1 in the region of the connection between the base body and the closure body before and after the connection of the base body to the closure body in longitudinal section.
  • FIG. 1 shows a container 10 according to the invention, which is designed in particular for filling foodstuffs, in particular for the aseptic filling of liquids.
  • the container 10 comprises a in
  • base body 1 1 which consists of a multi-layer cardboard material.
  • a multi-layer cardboard material is understood to mean a material which consists of several layers of packaging material, wherein at least a first
  • Packing material layer is a cardboard layer and at least a second
  • Packing material layer consists of plastic, preferably HDPE or LDPE, wherein the at least one plastic layer on the outside of the base body 1 1 is arranged.
  • a plastic layer also preferably made of HDPE or LDPE, equipped.
  • additional layers may be provided in addition, for example, an aluminum layer serving as a barrier layer or the like.
  • the main body 1 1 is connected to a round bottom member 12 with a radially encircling edge, which preferably consists of a multi-layer cardboard material according to the structure of the main body 1 1.
  • the base body 1 1 surrounding the bottom member 12 at its outer periphery in register with the edge of the bottom member 12, wherein in one
  • Overlap or connection region 13 between the base body 1 1 and the bottom member 12 is a suitable connection between said elements, in particular an ultrasonic welding, a
  • Heat seal adhesive or the like is formed and provides for the required tightness.
  • the bottom element 12 may also be made of plastic, wherein it is then preferably produced by injection molding.
  • the bottom portion 12 opposite end portion of the base body 1 1 is connected to a likewise made of plastic, designed as an injection molded part, sleeve-shaped closure body 15.
  • Closure body 15 consists of a compared to the outer layer of the base body 1 1 similar plastic, i. preferably also from HDPE or LDPE.
  • the closure body 15 may comprise a closure element or cover element, not shown in detail, which is connected to the closure body 15, for example via a thread 16 formed on the closure body 15, in order to allow the removal of the filling material from the container 10 after removal of the lid element.
  • the closure body 15 has a cylindrically shaped connecting portion 18 which is insertable into the inner circumference of the base body 1 1.
  • a conical transitional region 19 Connected to the connecting section 18 is a conical transitional region 19 which is only partially visible in FIG. 2 and which merges into a head region 20 (FIG. 2).
  • Closure body 15 with a maximum of only a small radial distance or gap.
