Definitions

  • the invention relates to a blank, as well as a sleeve-shaped outer part formed from a blank for encasing a cup-shaped container, as well as a combination packaging container formed from a container and an outer part.
  • the invention further relates to a method for producing a combination packaging container, as well as a method for opening a combination packaging container.
  • the WO 2020/245148 A1 by the same applicant describes a sleeve-shaped outer part formed from a blank, wherein the blank is wound into a jacket and the end sections of which are connected to one another in an overlapping area.
  • the sleeve-shaped outer part forms a combination packaging container together with a cup-shaped inner container.
  • a predetermined separation area comprises an actuating means with a detection section for separating separation sections on both sides. In a combination packaging container designed in this way, the predetermined separation area is intended to be separated after the container has been used, which is why separation of the components and subsequent recycling or reuse is not guaranteed.
  • the object of the present invention was to overcome the disadvantages of the prior art and to provide a blank, an outer part and a combination packaging container in which the sleeve-shaped outer part can be easily removed from the container for recycling purposes and in which it is ensured that a user carries out this separation.

  • the blank has a receiving area and an area, which area, viewed in longitudinal extension, is arranged between the receiving area and the second end face.
  • the blank according to the invention has the surprising advantage that the receiving area and the area which, viewed in the longitudinal direction, is arranged between the receiving area and the second end face make it possible to ensure that the blank and a cup-shaped container wrapped with the blank have to be separated from one another in order to enable access to a filling material contained in the container. This can ensure improved separation and recycling.
  • the blank can form high-quality and attractive outer packaging for a container, whereby the blank can also fulfill a function as proof of originality and is therefore considered "tamper evident".
  • the cut is particularly, but not exclusively, suitable for wrapping reusable containers, especially reusable plastic containers. After the separation from the wrapped container required for use of a container, the cut can be recycled in a largely pure form, while a container can be subjected to a reuse process.
  • the cut-out can be a part cut from a sheet or a sheet-like element, for example from paper, cardboard, or even from a thin plastic sheet.
  • the receiving area can be a This can be a cutout, a hole or an opening in the blank.
  • the receiving area can be cut or punched out of the blank, for example. It is also conceivable that the receiving area comprises an elongated slot or is an elongated slot through which a sealing edge, collar or similar of a container can be passed.

  • This shape of the receiving area has the advantage that it is possible to reliably accommodate a container or areas of a container.
  • the exact length i.e. an absolute value of the length, depends on the shape and size of the container to be covered with the outer part, and in particular on the maximum diameter or circumference of the open end.

  • the second receiving area front side facing the second front side is spaced apart from the second front side by a first length when viewed in the longitudinal extension of the outer part.

  • the second length can also vary. This is particularly the case if the first end face of the outer part does not follow an exact circular arc shape, but is, for example, wave-shaped. In this case, it has also proven expedient for the second length to be greater than the first length.
  • the maximum first length and the maximum second length define a maximum annular segment height, which annular segment height corresponds in particular to a maximum longitudinal extension of the outer part or a maximum construction height.
  • first end face and/or the second end face are formed in the shape of a circular arc, or that the first end face and/or the second end face are formed in the shape of a wave or sinusoidal curve.

It can be sufficient if the predetermined separation area does not extend over the entire longitudinal extent or height of the casing of the outer part, but only extends from the lower first end face to the first receiving area end face. It is also conceivable that the predetermined separation area is formed in such a way that when the predetermined separation area is separated, not the entire outer part is separated, but that it remains partially on the container, but a user still has access to the container contents, or a closure element can be removed after partial separation.

  • the combination packaging container comprises a cup-shaped container, wherein the container has a container shell which has an open end, which open end is closed with a closure element, and which has an end closed with a base.
  • the combination packaging container further comprises an outer part, which outer part encases the container, wherein the outer part is formed from a blank, which blank has a substantially circular ring-segment-shaped basic shape, which blank has a first end section and a second end section, wherein the blank is wound into a shell and the first end section and the second end section are coupled to one another in an overlapping region, wherein the outer part further has a first end face and a second end face and the first Front side and the second front side are spaced apart from one another, wherein the outer part has a longitudinal extension in a direction starting from the first front side to the second front side, wherein a predetermined separation region is provided in the jacket of the outer part, and wherein the jacket of the outer part has a receiving region and a region, which region, viewed in the longitudinal extension, is arranged between the receiving region and the second front side, wherein a region of the open end and/or a region of the closure element is received in the receiving region.
  • the separation of the outer part from the container by opening the intended separation area can be complete, partial or partial.
  • the outer part or part of the outer part is separated in such a way that the closure element can be removed after removal.
  • the method according to the invention for opening a combination packaging container has the surprising advantage that a user is shown or guaranteed that he is opening the original sealed container for the first time.
  • a user is virtually forced to separate the outer part from the container and is thus encouraged to recycle because he would otherwise not have access to the contents of the container. This therefore makes a significant contribution to sustainability. This is particularly true if the method for opening or for opening for the first time is carried out in the order described.
