Definitions

  • the present invention relates to a container having a container body made of plastic, which has a container wall, wherein the container wall has a first container wall portion and a second
  • Container wall portion wherein the first
  • Container wall section is provided with a label, wherein the
  • Container body is a plastic injection molded part, which is produced using an injection mold, wherein the container body and label are characterized in that in the manufacture of the container body, the label inserted into the injection mold and then the plastic are injected into the injection mold, wherein the container wall a
  • Container wall section connects.
  • the invention further relates to a method for manufacturing a container having a container body with a container wall, wherein the container wall has a first container wall portion and a second container wall portion, wherein the container body is produced by injection molding using an injection mold and thereby provided with the label, wherein the label is joined to the container body by placing the label in the injection mold and subsequently injecting the plastic into the injection mold, the container wall having a connection portion connecting the first and second container wall portions.
  • the production of a container in which a label is inserted into an injection mold and subsequently the plastic is injected into the injection mold is also known as in-mold or in-mold labeling designated.
  • Advantage of this method is that the label can be prepared separately in advance, for example by way of printing. This allows a versatile and attractive design of the label.
  • the label can also fulfill a technical function and contribute, for example, to gas tightness.
  • the injection process is to be designed so that the plastic material does not move the inserted into the injection mold label and no plastic material reaches the outside of the label.
  • the manufacturing problems are more pronounced when the containers are small.
  • the in-mold labeling of containers is known, for example, from DE 10 2005 037 274 A1, which describes a cylindrical container produced by an in-mold process.
  • DE 10 2005 037 274 A1 addresses the problem that the production of small diameter cylindrical moldings by in-mold labeling poses problems.
  • DE 10 2005 037 274 A1 attempts to remedy this by using a molding tool which has a radius of at most 3.0 mm between a lateral surface and a base surface of a molding space.
  • the present invention therefore has the object to improve the production in particular of a container with small dimensions.
  • the object is achieved in a container having the features of claim 1 and in a method having the features of claim 13. Accordingly, it is provided in a container and method mentioned above that the outer contour of the connection region has sections which are arranged along a free-form line. It has been found in practice that this design contributes to a better filling behavior of the injection mold. The safety of the process can be improved, and the risk of liquid plastic reaching the outside of the label during the injection molding process is reduced. Moreover, the provision of an outer contour, which is arranged along a free-form line, helps to improve the flow behavior of the plastic in the injection molding in such a way that the difficulties encountered in the in-mold process are avoided and in particular no plastic undesirable on the outside of the Label arrives.

  • the straight surfaces may be formed as facets.
  • a further improvement of the production is achieved if between the first container wall portion and the connecting portion a shoulder is formed, which is formed by a arranged on an outer side of the container body thickening of the container wall.
  • connection region and / or the first container wall section is rotationally symmetrical.
  • the first container wall section forms a container sidewall and the second container wall section forms a container bottom.

La paroi de récipient (3) comporte une première partie de paroi de récipient (4) et une seconde partie de paroi de récipient (7). La première partie de paroi de récipient (4) est pourvue d'une étiquette (5). Le corps de récipient (2) est une pièce en matière plastique moulée par injection qui est fabriquée à l'aide d'un moule d'injection. Le corps de récipient (2) et l'étiquette (5) sont reliés en raison du fait que, lors de la fabrication du corps de récipient (2), l'étiquette (5) est insérée dans le moule d'injection puis la matière plastique est injectée dans le moule d'injection. La paroi de récipient comporte une zone de liaison (11) qui relie les première et seconde parties de paroi de récipient (4, 7). L'invention est caractérisée en ce que le contour extérieur de la zone de liaison (11) comporte des parties (13, 13') qui sont disposées le long d'une ligne de formage libre.
