Description

Hinged containers and blanks

The present invention relates to a hinged lid comprising a container and a lid, wherein the lid is biased open when the container is opened and biased closed when the container is closed. The present invention also relates to blanks for such packs.

Packs of this type, including containers and leads, are used to contain many types of consumer products, such as food and articles suitable for smoking. The container and lid are typically connected together by a hinge, often an integrally formed hinge, the hinge allowing the lid to pivot away from the container when it opens, allowing the consumer to approach the product from the inside and then pivot again The pack can be reclosed. The material of the configuration of the hinge deflects by being supported on any of the open or closed positions, particularly when it is integrally formed with the container and the lid. This can interfere with smooth removal of the product from within the container or prevent complete and effective closure of the container after opening. Is the container flip-top? In the case of a hinged lead pack of the type, the inner frame of such a container can be seen as a so-called "smile" effect when the container is not entirely closed. It is known from DE 66 55 75 to include a spring in such a vessel to keep the lid open. Additional elements may be provided to interact with the spring to maintain the lid closed.

It is an object of the present invention to provide reduced smearing of the container.

According to a first aspect of the present invention, there is provided a container comprising a box and a lead, the lead being dependent from a box through a transverse main hinge line, the main hinge line comprising a central hinge section and two adjacent hinge sections Wherein the central hinge section is separated from two adjacent hinge sections by a cut and the central hinge section is bounded by an upper hinge line, the upper hinge line including a central hinge section and a lead and a lower hinge line, And the lower hinge line connects the center hinge section and the box. The biasing member is connected to a lead on the central hinge section on one side and to a box below the central hinge line on the other side. The biasing member extends through the central hinge section to be under tension to deflect the lid to closing when the container is closed and to deflect the lid to open when the container is opened.

In use, the central hinge section will fold out of the rear wall of the container along the upper and lower hinge lines. This means that when the lead pivots backward around the hinge line, the biasing member bends through the center hinge section, but the biasing member bends at a position below the hinge line. This means that as the lid pivots backward, the biasing member is first stretched to extend the distance between the two retention points of the biasing member on the back wall of the vessel. However, when the lead is bent more, there is a turning point, where the extension of the biasing member is maximum. After such a point, further pivoting of the leads will actually release the tension from the biasing member, since the biasing member is stretched only about the lower hinge line and the upper hinge line, rather than extending around the main hinge line, Supporting the further opening and maintaining the lead in the open position.

Advantageously, the biasing member is attached to the inner side of the lead top wall at the lead retention point by a distance of about 2 mm to about 15 mm, preferably about 3 mm to 8 mm, from the lead rear wall. Thus, the turning point is the point at which the biasing member is aligned when the lead is pivoted again, substantially parallel to the rear wall of the vessel, i. E. The distance of the lead holding point of the biasing member is above the main hinge line.

As used herein, the term "container" refers to a substantially rigid package or box that includes a box for a product and a lid that is open to remove the product from the box and can be reclosed to protect the product from the environment do. Such a package is self-supporting and, once formed, has a size and shape that does not significantly change upon insertion into and removal of the product from the product. When the consumer product is a smoking article, the container typically stands around the smoking article. Advantageously, the container according to the invention has a flip-top? It has the same shape as the box. Preferably, the container is substantially rectangular parallelepiped. More preferably, the container is square in cross-section and is in the form of a carton. It will be appreciated that packs according to the present invention may be designed to contain different numbers of smoking articles, such as cigarettes, through a suitable choice of their dimensions.

The container according to the first aspect of the present invention may be formed of any suitable material including, but not limited to, a cardboard, a paperboard, a plastic, a metal, or a combination thereof. The paperboard may have a weight of from about 100 g / m 2 to about 350 g / m 2. Preferably, a laminated paper is used. For example, the package may consist of a laminate paper coated with polyethylene on the intended interior of the package or a sandwich layer of thin aluminum foil between the outer kraft paper or board and the inner polyethylene coating.

The hinge wire according to the first aspect of the invention may comprise any suitable hinge or bending mechanism. Advantageously, the hinges and bend lines are each individually embossed, ablated, wrinkled or scored. Preferably, the hinges and lines of flex are wrinkled.

According to an embodiment of the first aspect of the invention, the container may comprise an additional center hinge section, each additional center hinge section being associated with its own biasing member, Each hinge member being under tension to deflect the lid to closure when the container is closed and to deflect the lid to open when the container is open, Lt; RTI ID = 0.0 > hinge < / RTI > In such a case, each additional center hinge section includes two cuts intersecting the hinge line.

The biasing member according to the first aspect of the present invention may have any suitable configuration to achieve the desired function of deflecting the lid to closing when the container is closed and deflecting the lid to open when the container is opened. The biasing member may comprise a strip of material extending substantially from one of the cuts to the other to extend substantially throughout the central hinge section. Alternatively, the biasing member may extend laterally only a portion of the center hinge section of the distance between the two cuts and within the central hinge section. In another embodiment, there may be more than one biasing member disposed between the two cuts and within the central hinge section. In such a case, each biasing member may comprise a thread.
