Description

  The present invention relates to a hinge lid container having a container and a lid. The lid is biased and opened when the container is open, and the lid is biased and closed when the container is closed. The invention also relates to a blank for such a pack.

  This type of pack with containers and lids is used to accommodate many types of consumer goods such as food and smokable items. The container and lid are typically connected to each other via a hinge (often an integrally formed hinge) so that the lid can pivot away from the container when opening the container. This gives the consumer access to the inner consumer goods and then pivots back to reclose the pack. The material of the hinge structure typically biases one or the other of the open or closed positions, particularly when it is integrally formed with the container and lid. This may prevent smooth removal of the consumer goods from the container, or it may prevent complete and effective closing after the container is opened. If the container is a flip top ™ type hinge lid pack, when the container is not fully closed, the inner frame of such container may become visible, which is referred to as the so-called “smileing” effect. It is known from German Patent DE 665 575 to include a spring in such a container to hold the lid open. There may be additional elements that interact with the spring to hold the lid closed.

  An object of the present invention is to provide a container with reduced smile.

  According to a first aspect of the invention, the container is provided with a box and a lid, the lid being subordinate to the box via a transverse main hinge line, the main hinge line being a central hinge section and two adjacent hinges The central hinge section is separated from two adjacent hinge sections by a cut, and the central hinge section has an upper hinge line (the upper hinge line connects the central hinge section and the lid) and a lower hinge line (lower The hinge line is further delimited by a central hinge section and box). The biasing member is connected to the lid on one side above the central hinge section and on the other side to the box below the central hinge line. The biasing member is under tension to bias and close the lid when the container is closed, and extends through the central hinge section to bias and open the lid when the container is open.

  In use, the central hinge section will fold outwardly of the rear wall of the container along the upper and lower hinge lines. This means that when the lid is pivoted back around the hinge line, the biasing member is bent through the central hinge section, but the biasing member is bent at a position below the hinge line. This means that as the lid pivots backwards, the biasing member is first extended further, extending the distance between the two holding points of the biasing member on the rear wall of the container. However, when the lid is further bent, there is an inflection point at which the extension of the biasing member is maximized. After that point, the biasing member is not stretched around the main hinge line, but only around the lower and upper hinge lines, so further pivoting of the lid is actually the tension of the biasing member So that the biasing member supports further opening and holds the lid in the open position.

  Advantageously, the biasing member is mounted inside the lid top wall at a lid holding point at a distance of about 2 to about 15 mm (preferably about 3 to 8 mm) from the lid rear wall. Thus, the inflection point is essentially the point where the biasing member is aligned parallel to the rear wall of the container, i.e. the lid is positioned so that the distance of the lid holding point of the biasing member is above the main hinge line. It is time to pivot back.

  As used herein, the term “container” comprises a box for consumer goods and a lid that can be opened to remove the consumer goods from the box and closed again to protect the consumer goods from the environment. , Refers to a substantially rigid package or box. Such packages are self-supporting and, once formed, have a size and shape that does not change significantly upon insertion and removal of consumer goods therein. When the consumer good is a smoking article, the container is typically erected around the smoking article. Advantageously, the container according to the invention has the same shape as the Fliptop ™ box. The container is preferably substantially rectangular parallelepiped. More preferably, the container has a rectangular cross section and is in the form of a carton. Of course, packs according to the present invention may be designed to accommodate different numbers of smoking articles (such as cigarettes) by appropriate selection of their dimensions.

  The container according to the first aspect of the present invention may be formed from any suitable material, including but not limited to cardboard, paperboard, plastic, metal, or combinations thereof. The weight of the cardboard may be from about 100 grams / square meter to about 350 grams / square meter. It is preferable to use laminated paper. For example, the package is constructed with a laminated paper coated with polyethylene on the intended inside of the package, or a layer of thin aluminum foil sandwiched between the outer kraft paper or paperboard and the inner polyethylene coating. May be.

  The hinge wire according to the first aspect of the invention may comprise any suitable hinge mechanism or bending mechanism. Advantageously, each of the hinge and fold line is separately embossed, cut, creased, or parted, separately from each other. The hinge and fold line are preferably creased.

  According to one embodiment of the first aspect of the present invention, the container may comprise an additional central hinge section, each additional central hinge section being associated with its respective biasing member, each biasing The member is connected to the lid over the central hinge section on one side and connected to the container over the central hinge section on the other side, each biasing member biasing the lid when the container is closed And is under tension to close and extends through the central hinge section to bias open the lid when the container is open. In such cases, each additional central hinge section comprises two cuts that intersect the hinge line.

  The biasing member according to the first aspect of the present invention may be any suitable that achieves the desired function of biasing and closing the lid when the container is closed and biasing and opening the lid when the container is open. You may have a structure. The biasing member may comprise a strip of material that extends substantially from one of the cuts to the other so as to extend substantially across the entire central hinge section. Alternatively, the biasing member may extend laterally only a portion of the distance between the two cuts and only within the central hinge section. In another embodiment, there may be two or more biasing members disposed between the two cuts and in the central hinge section. In such cases, each biasing member may comprise a thread.

  The biasing member according to the invention is connected to the lid on one side of the hinge wire by thermal bonding, by adhesive, by mechanical means (such as one or more staples) or by a mixture thereof, It may be connected to the container on one side. Advantageously, the biasing member is connected to the lid and the container by thermal bonding, in particular ultrasonic welding.

  The biasing member according to the invention may comprise an elastomer, in particular a non-woven elastomer. Such materials are well known to those skilled in the art. This is connected, for example, to the lid and the container under tension by stretching during application.

  Preferably, the biasing member is already under tension when applied to the blank from which the container is made. Alternatively, the biasing member may be tensioned after application to the blank, for example by contracting the biasing member (eg, using heating).

  According to a second aspect of the present invention, an elongated blank for a container having a box and a lid is provided, the elongated blank comprising a box defining portion and a lid defining portion, the lid defining portion having a transverse main hinge line. The main hinge line comprises a central hinge section and two adjacent hinge sections, the central hinge section is separated from the two adjacent hinge sections by a cut, and the central hinge section is the upper hinge Line (the upper hinge line connects the central hinge section and the lid defining part) and the lower hinge line (the lower hinge line connects the central hinge section and the box defining part), and the elongated blank is Lid delimiter on the side above the central hinge section And further comprising a biasing member connected and connected to the box defining portion beyond the central hinge section on the other side, the biasing member being under tension when the formed container is closed and It is configured to bias and close, and is configured to extend through the central hinge section to bias and open the lid when the formed container is open.
