Definitions

  • the present invention relates to a humidifying insert, for a smoking articles packaging, wherein the humidifying insert has a planar shape, is insertable into a smoking articles packaging and comprises a humidifying agent and a humidity transmitter, which transfers the humidifying agent from the humidifying insert into the inner volume of the smoking articles packaging.
  • the invention also relates to a method for humidifying smoking articles.
  • the smoking articles packaging is normally sealed to prevent or limit air circulation between the inner volume of the smoking articles packaging and its surrounding, which could lead to a loss of moisture of the smoking articles contained in the smoking articles packaging.
  • smoking articles can easily exhibit unwanted drying, which negatively affects the sensory experience. It is therefore the objective of the invention to provide a device and method to prevent or min imize the moisture loss or the drying of a smoking article in an at least once opened smoking articles packaging, and to maintain the quality, taste and overall sensory experience of the smoking article during use by consumers.
  • the invention therefore comprises a humidifying insert, for a smoking article packaging, wherein the humidifying insert has a planar shape, is insertable into a smoking article packaging and comprises a humidifying agent and a humidity transmitter, which transfers the humidifying agent from the humidifying insert into the inner volume of the smoking article packaging.
  • the invention is characterized by a storage compart ment, in which the humidifying agent is stored, having a fluidic connection to the humidity transmitter, wherein the fluidic connection is blocked with a breakable barrier.
  • the humidifying insert comprises a planar shape. With the planar shape, the humidifying insert is easily insertable into the smoking articles packaging. With the humidifying agent transferred into the inner volume of the smoking articles packaging by the humidity transmitter, the smok ing articles contained in the smoking articles packaging are humidified. By storing the humidi fying agent in the storage compartment, which has a fluidic connection to the humidity trans mitter and the fluidic connection being blocked with a breakable barrier, the humidifying insert can be activated by breaking the breakable barrier. This ensures, that the user can activate the humidifying insert on demand.
  • the humidifying insert is activated by the con sumer after the first opening of the smoking articles package. In this way, the smoking articles contained in the smoking articles package remain humidified and/or moisturized after the smoking articles packaging has been opened for the first time. In this way, constant product freshness from first to last smoking article in the smoking articles packaging can be ensured.
  • the humidifying agent As long as the breakable barrier is intact, the humidifying agent is kept in the storage compart ment and cannot exit the humidifying insert. At this point, the humidifying insert is in an inacti vated state.
  • the humidifying agent By breaking the breakable barrier, the humidifying agent can pass from the storage compartment through the fluidic connection to the humidity transmitter, which then transfers the humidifying agent from the humidifying insert into the inner volume of the smoking articles packaging. At this point, the humidifying insert is in an activated state.
  • the possibility to activate the humidifying agent by breaking the breakable barrier is highly advantageous, as the humidifying insert will humidify the smoking articles only on demand of the user.
  • the humidifying agent in its inactivated state can be packed with the smoking articles in the smoking articles packaging already at the production site (compatible with inline packaging) and will not be expended, as long as the original packaging and sealing remains intact and the smoking articles are prevented from drying by the sealing.
  • the user may decide that a humidification of the smoking articles is not necessary yet and may postpone the activation of the humidifying insert according to individual demands.
  • the storage compartment and the humidity transmitter are enclosed between a front and a back sheet material layer.
  • a sheet material is a material of laminar shape, i.e. having a size, in one dimension in a 3-dimensional space X, Y, Z, being at most a tenth of that in the other two dimensions.
  • any parts enclosed between the front and back sheet materials can be positioned on the back sheet material with subsequent arrangement of the front sheet material on top of the back sheet material and the parts positioned on it. After this positioning the front and back sheet materials can be affixed to each other at least in part enclosing all parts previously positions on the back sheet material in between. This denotes a very simple and effective way of production of the humidifying insert, which is therefore also cost effective.
  • the front and back sheet material layers are affixed to each other at least circumferentially along the edges of sides of the front and back sheet material layers facing each other, wherein at least a center part of the front and back sheet material is unaffixed to each other forming a cavity enclosing the storage compartment the humidity trans mitter.
  • This is a very simple and efficient way to form the storage compartment. No other parts than the front and back sheet material layers are needed to manufacture the storage compart ment.
  • the cavity may also enclose the humidifying agent, the humidity transmitter and/or the breakable barrier. It may also be desirable to pro Jerusalem the humidifying insert without the humidifying agent and fill the storage compartment in a subsequent step with the humidifying agent.
  • the storage compartment is sealed after placing the humidifying agent in it, so the humidifying agent is securely contained in the storage compartment.
  • the front and back sheet material is a composite film, com prising at least two material layers.
  • the material layers of the composite film consist of different materials.
  • the at least two material layers preferably consist of a plastic material.
  • the material layers consist of different plastic materials.
  • the composite film comprises a first layer of polyethylene terephthalate, a second layer of polyethylene terephthalate coated on at least one side with a coating layer and a third layer of polyethylene.
  • the coating layer is aluminum oxide (AIOx).
  • the first layer of polyethylene terephthalate (PETP) comprises a layer thick ness of 5 to 20 pm, especially preferable 12 pm.
  • the second layer of PETP also comprises a layer thickness of 5 to 20 pm, preferably 12 pm.
  • the third layer of polyethylene (PE) preferably comprises a layer thickness between 20 and 70 pm, especially preferable 50 pm.
  • the coating of at least one side of the second PETP film with an aluminum oxide is ad vantageous, as the initially transparent PETP film appears silver or white depending on the type and/or particle size of the aluminum oxide.
  • the aluminum oxide may also be mixed with any type of pigment to realize any kind of color.
  • Silicon Oxide (SiOx) coated films may be used in lieu of AIOx coated PET films.
  • the composite film is printable.
  • any kind of text or pictures can be printed on the humidifying insert.
  • the outer surface of the humidifying insert may be printed on completely or in part. If the outer surface of the humidifying insert is printed only in part, the combination with the aluminum oxide coated PETP-layer is highly advantageous, as the aluminum oxide may provide the base color of the humidifying insert supplemental to the printing of the composite film. In this way it is not nec essary to print the whole surface of the humidifying insert.
  • the printed text or pictures may comprise user information on how to use the humidifying insert. Alternatively or in addition, the printed text or pictures may comprise logos, brand names or further embellishments or user information.
  • the front sheet material comprises perforations located at the humidity transmitter establishing a second fluidic connection between the humidity trans mitter and the atmosphere surrounding the humidifying insert.
  • the second fluidic connection penetrates through the front sheet material.
  • the humidifying agent can easily pass from the humidity transmitter through the front sheet mate rial.
  • the humidity transmitter is enclosed in the cavity between the front and back sheet material.
  • the sheet material itself can be liquid tight, if the humidity transmitter is enclosed in the cavity between the front and back sheet material.
  • Perforations are the easiest and most cost effective way to establish the second fluidic con nection.
  • the back sheet material may also comprise perforations.
  • the perforations exhibit a hole size of 0.01 to 4 mm, prefer ably 0.1 to 3 mm.
  • the perforation preferably is a micro perforation, i.e. a sub-millimeter diameter perforation.
  • the hole size determines the transmission rate of the humidifying agent through the perforation. The larger the hole size, the larger is the transmission rate of the humidifying agent through that specific hole.
  • the transmission rate of the humidifying agent is adjustable via the hole size.
  • the hole size is preferably chosen to establish an optimal transmission rate of the humidifying agent with re gard to an optimal humidification of the smoking articles contained in the smoking articles packaging in terms of humidification level and/or duration.
  • the perforations comprise at least 1 up to 200 holes.
  • the hole number of the perforation By adjusting the hole number of the perforation, the transmission rate of the humidifying agent through the perforation can be adjusted.
  • a smaller hole size combined with a larger number of holes can be advantageous.
  • the hole number is preferably chosen to establish an optimal transmission rate of the humidifying agent with regard to an optimal humidification of the smok ing articles contained in the smoking articles packaging in terms of humidification level and/or duration.
  • the hole number and size are chosen in a specific combination to achieve an optimal humidification of the smoking articles contained in the smoking articles packaging in terms of humidification level and duration.
  • the humidity transmitter comprises a tissue material located directly at the perforations between the front and back sheet material.
  • the tissue material can absorb the humidifying agent, when transferred from the storage compartment to the humidity transmitter, and then slowly release the humidifying agent.
  • the use of the tissue material en ables an additional option to adjust the transmission rate of the humidifying agent from the humidifying insert into the inner volume of the smoking articles packaging.
  • This makes the humidifying insert more versatile and compatible with more types of humidifying agents.
  • the tissue material is a fleece tissue. But it is also conceivable to use any other tissue material suitable for this application.
  • the breakable barrier is a seal varnish.
  • a seal varnish is a very easy way of establishing a breakable barrier in the fluidic connection between the storage compartment and the humidity transmitter.
  • a varnish offers the advantage of being provided in a liquid state which dries into a solid state after application of the varnish to a surface.
  • the humidifying insert is preferably produced by layering the components contained in the humidifying insert on the back sheet material, forming a stack.
  • the seal varnish can be deposited at the desired position of the breakable barrier on the back sheet material, preferably in the fluidic connection between the storage compartment and the humidity transmitter.
  • the front sheet material is positioned on top of the stack.
  • the seal varnish affixes the front and back sheet material at each other at the position of the breakable barrier. This fixation of the front and back sheet material with the seal varnish is breakable. In this way a breakable barrier at the desired position is formed.
  • the breakable barrier consists of one or multiple materials, which are not varnishes. Any material being impermeable to the humidifying agent and being breakable is possible.
  • the barrier may com prise a predetermined breaking point. Preferably, this is achieved by a thinner material thick ness at the predetermined breaking point.
  • the breakable barrier is breakable with a pressure gradient between the storage compartment and the humidity transmitter.
  • the breaking of the breakable barrier with a pressure gradient is a very simple and easy to apply method for the user.
  • the user simply has to pressurize the storage compartment of the humidifying insert. This pressurization can be accomplished by pressing the storage compart ment in a direction of the surface normal of the front and back sheet material.
  • the pressuriza tion may also be realized by folding the humidifying insert along a folding axis being parallel to the surface of the front and back sheet material and intersecting the storage compartment. The intersection of the folding axis with the storage compartment divides the storage compartment into two sub-compartments. When folded along the folding axis, the pressure in the sub-com partments is increased due to the overall reduction in volume of the storage compartment caused by pressing the front and back sheet material together at the folding axis.
  • the higher pressure in the storage compartment in comparison with the unpressurized humid ity transmitter creates a pressure gradient between the two. This pressure gradient breaks the barrier and allows the humidifying agent to pass through the fluidic connection from the storage compartment to the humidity transmitter.
  • the humidity transmitter preferably comprises the perforations of the front sheet material. This means, that an inner volume of the humidity transmitter is connected to the surrounding of the humidifying insert via the second fluidic connection. Therefore, the humidity transmitter prefer ably comprises ambient pressure.
  • the storage compartment may be pre-pressurized by the amount of humidifying agent and/or another liquid or gaseous substance in the storage compartment.
  • the humidifying agent is a water-based solution.
  • a water-based solution provides a very cost effective possibility for a humidifying agent.
  • the humidification of smoking articles with a water-based solution is also beneficial, as water is a natural humidification agent and the addition of unnecessary chemicals can be omitted.
  • the humidifying agent consists of pure water.
  • the humidifying agent may also com prise salt, thickening agents (e.g. an alginate) and/or flavoring agents.
  • the humidi fying insert contains 1 ,2 g of humidifying agent, preferably 1 ,2 g of water.
  • a method for humidifying smoking articles in a packaging with a humidifying insert which has a planar shape and comprises a humidifying agent, a humidity transmitter and a storage compartment, in which the humidifying agent is stored, wherein the storage compartment has a fluidic connection to the humidity transmitter, wherein the fluidic connection is blocked with a breakable barrier, comprising the steps:
  • the humidifying insert is inserted or reinserted into a smoking articles package.
  • the humidity transmitter preferably comprises a tissue material, preferably a fleece, woven or non-woven, tissue, which absorbs the humidifying agent in the humidity transmitter and then slowly releases the humidifying agent from the humidity transmitter into the inner volume of the smoking articles package, preferably via the perforations of the front sheet material.
  • the humidifying insert is inserted into the smoking articles packaging with the front sheet material facing the smoking articles. In this way, the humidifying agent evaporates towards the smoking articles, humidifying the surrounding environment.
  • the storage compart ment is pressurized by folding the humidifying insert in the area, where the storage compart ment is located.
  • Folding is a very simple and easy to apply method for the user to pressurize the storage compartment.
  • the folding axis is aligned parallel to the surface of the humidifying insert.
  • the folding axis is aligned parallel to the front and back sheet material.
  • the folding axis intersects the storage compartment.
  • the preferably printable surface preferably comprises indications for the use how and where to fold and/or pressurize the hu midifying insert.

  • a combination of pressurizing and folding of the humidifying insert 1 is also possible.
  • the user first pressurizes the storage compartment 6 at the position of first the sub-compartment 6b. This leads to a movement of the humidifying agent 3 towards the break able barrier 8, as the room for the humidifying agent 3 in the storage compartment 6 is reduced. This already creates a certain pressure gradient between the storage compartment 6 and the humidity transmitter 4. Then the humidifying insert 1 is folded along the folding line F. This further reduces the room for the humidifying agent 3 creating an event higher pressure gradient between storage compartment 6 and humidity transmitter 4. In this way it is possible to use a breakable barrier 8, which needs a higher pressure gradient to be broken. This can be benefi cial, as it reduces the possibility of accidentally breaking the breakable barrier 8, which would lead to an unwanted and/or untimely activation of the humidifying insert 1.
