Definitions

  • the invention relates to a package, which is preferably to be used for foodstuffs.
  • carton or cardboard packages which contain confectionary products such as pieces of chocolate, can be additionally wrapped in plastic overwraps which are usually heat sealed or formed as shrink films.
  • EP 0 796 208 B1 discloses a package comprising a lid which is additionally covered by a plastic film.
  • the plastic film can, after the package has been opened for the first time, be re-closed to the rim-like upper part of the base of the package. Also this type of opening area for a package is comparably complicated.
  • a package which is particularly intended to contain foodstuffs, comprises on the one hand a base having contact areas.
  • the contact areas will most preferably be arranged such that they are located in one and the same plane and allow the formation of an hermetic seal in cooperation with corresponding contact areas of a lid.
  • the contact areas of the base do not necessarily have to be arranged in one plane. Rather, they can be of an arbitrary structure as long as a seal can be formed which entirely seals the contents from the environment.
  • the inventive package further comprises a lid.
  • the lid is made of cardboard or rigid paper.
  • the lid comprises contact areas which are adapted to get into contact with the contact areas of the base so as to cooperate in forming an hermetic seal for the contents of the base.
  • both the base and the lid comprise surface areas which extend over certain, usually strip-like, surface portions in order to form a seal between the lid and the base.
  • the cooperating contact areas will be formed completely circumambient so that the product contained in the package is entirely protected against infestation, moisture, odour, light and oxygen.
  • the contact areas are preferably formed completely circumambient, they could be considered a single, continuous contact area.
  • the hermetic seal formed between the lid and the base is a re-closable adhesive seal, preferably a cold seal.
  • the contact areas of the base and/or the lid will usually be provided with a certain sealing agent which allows the lid to be bonded to the base when the package is filled with its contents and then closed, thus forming an hermetic seal.
  • the inventive package is convenient for the customer in that the seal between the base and the lid is the only seal which has to be opened in order to get access to the contents. In particular, the consumer does not have to open any overwraps or inside plastic bags.
  • the seal offers an additional consumer benefit in that it is reclosable. Thus, once the package has been opened, it can be reclosed so that the contents of the product do not fall out and, furthermore, are protected from moisture etc. entering the package.
  • the lid which is according to the invention made of cardboard or rigid paper, can naturally be coated with paint or any other suitable coating material, which appears necessary for providing certain written information on the package and/or for allowing the sealing agent to be suitably applied to the contact areas of the lid and/or base.
  • the material which forms the seal between the base and the lid i.e. the sealing agent can be applied to the contact areas of the base or the lid or even to the contact areas of both of these components.
  • the adhesive seal in accordance with the invention in particular the sealing agent, may only be formed on those contact areas between the lid and the base, which are remote from the mentioned fold line.
  • the contact areas extending from the fold line will be provided with the adhesive seal preferably such that the adhesive seal terminates at the fold line. In this manner, the seal is formed all around the package.
  • the sealing agent can be formed as a continuous bead.
  • a permanent pressure-sensitive adhesive is preferred.
  • This term describes any adhesive which keeps its adhesive characteristic even after the components, which adhere to each other, have first been taken apart.
  • pressure-sensitive describes the fact that, as soon as pressure is applied to the adhesive, it will exhibit its adhesive quality.
  • Most commonly known will be the notepads trading under the name "Post it”. These comprise a permanent pressure-sensitive adhesive which allows them to adhere to any desired object by applying pressure.
  • the same principle can be used in connection with the present invention which serves to provide an hermetic and, at the same time, reclosable adhesive seal between the base and the lid.
  • the invention does not prevent additional seals from being present in order to further enhance protection against the environment.
  • the adhesive seal between the lid and the base is the only seal which is present between these components.
  • the lid of the inventive package is made of cardboard or rigid paper and it can be said that the invention for the first time suggests a adhesive seal formed on contact areas of a lid made of such a material to be applied to a package.
  • the base and, in particular for the entire package that it be paper-based i.e. made of cardboard, rigid paper or a similar material.
  • the lid and the base are integrally formed from one end of the same cardboard blank.
  • the inventive package 10 essentially consists of a base 12 and a lid 14. It is, however, to be understood that further components can be present within the base 12 and/or on the lid 14. For example, one or more shaped plastic trays can be accommodated within the base 12 in order to receive one or more products such as pieces of chocolate or confectionary products.
  • the base 12 is essentially formed as a generally rectangular box comprising a circumambient collar or rim 16, of which two portions can be seen in the cross-sectional view of the figure. A channel-like formation is present underneath the rim in order to enhance its rigidity.
  • the circumambient strip like surface portions of rim 16, which face the lid 14, define those contact areas 18 which are adapted to cooperate with corresponding surface areas 20 of the lid 14.
  • the contact areas 18 and/or the contact areas 20 are provided with a suitable material so as to form an hermetic seal between the lid 14 and the base 12.
  • the lid 14 is bonded to the base 12 by means of contact between the contact areas 18 and 20, which are formed all the way around the package, the contents of the package are hermetically sealed from the environment.
  • the seal is finally formed in a reclosable manner so that the package can be opened and reclosed as desired.
  • the contact areas 18 of the base 12 could be provided with the inventive adhesive seal.
  • the contact area 18, which is adjacent the fold line connecting the lid 14 with the base 12, i.e. the left contact area 18 in the figure is free from sealing agent.
  • those contact areas of the lid 14 and/or the base 12, which extend parallel to the plane of the paper of the figure are provided with sealing agent, which extends up to the fold line between the lid 14 and the base, or almost to that fold, the desired sealing function is achieved.
