Description

  The present invention relates to a rigid package including a hinge-connected lid.

  In particular, the present invention finds a field that is remarkably useful in the manufacture of cigarette packs, with non-limiting implications, but is specifically referenced in the following detailed description.

  In general, a hinged lid-type rigid package has a parallelepiped shape at first glance, with the lid placed on the top and holding a group of cigarettes wrapped in each inner wrapping paper. Provide a container. The lid is hinged to the open upper end of the container so as to be rotatable between a position where the container is open and a position where the container is closed.

  The container is provided with an inner reinforcing support that functions as a connecting element between the container and the lid.

  In the prior art, the cross section is approximately triangular, has a sharp or rounded corner end, and a hinge that allows the pivoting movement of the lid is located on the side of the package opposite the front corner end A package of cigarettes having a prismatic shape is included. Such triangular packaging containers and lids have respective end surfaces that constitute the front and rear surfaces and the bottom and top of the packaging.

  Such a package with a triangular cross-section is partially attached to the container and partially protrudes from the container, and when the package is not used, an inner reinforcing support that serves to hold the lid in the closed position more easily is provided. Furthermore, it is equipped.

  One drawback faced by packages of this type, i.e. prismatic and triangular in cross section, is that after the lid has been opened a relatively limited number of times to remove the cigarette, despite the presence of the reinforcing support. , There is a tendency not to return again to the correct closed position in contact with the end of the container.

  The resulting partially open state of the package adversely affects subsequent tobacco maintenance, for example, with respect to tobacco scent and correct moisture content.

  Furthermore, the lid is not tightly closed on the container, resulting in a clear structural vulnerability of the entire package. When the lid remains open, in fact, the front corner end will easily deform if pressure is applied to the top tip of the corner end that matches the support.

  An object of the present invention is to provide a package that is not affected by the above-mentioned drawbacks.

  The above objects are clearly understood in accordance with the present invention as a rigid package with a hinged lid of features as cited in one or more of the appended claims.
