Description

[TECHNICAL FIELD TO WHICH INVENTION RELATES]

[0001] The present invention relates to packaging.

[LEVEL of TECHNOLOGY]

[0002] The surface of the package in which the product, such as a tobacco product, is packaged, may be varnished. As a technology for printing varnishes on packaging or on something else, a technology has been proposed to provide a matted knot and a glossy knot, while at the same time improving abrasion resistance (see, for example, Patent Document 1). A technology has also been proposed to prevent water-stained markings from developing even after wrapping the packaging in film by providing a protruding layer with a varnish printed in a protruding manner (see, for example, Patent Document 2).

[SUMMARY OF INVENTION]

[Problems to be solved by the invention]

[0004] Traditional lacquered packaging has a surface friction coefficient of only about 0.05 to 0.15. For example, the package may likely slip out at the time of opening or closing the lid, or the film may likely subside during wrapping the outside of the package with film.

[0005] The present invention has been made in view of the problems described above, and its task is to reduce the slippery surface of the package and improve convenience.

[Problem Solver]

[0006] To solve the problems described above, the package of the present invention is a package that houses a tobacco product in which at least a portion of the surface includes an area on which a water-soluble lacquer is applied containing urethane resin and water as main components.

[0007] The use of a water-soluble lacquer containing urethane resin can improve the coefficient of friction in the application. That is, the area on which the lacquer is applied functions as a safety device against slipping when the user handles the packaging, which improves convenience.

[0008] With regard to the coefficient of friction of the region on which the varnish is applied, the coefficient of friction with stainless steel can be from 0.2 to 0.5. If the coefficient of friction is within the range, the area is preferred as a safety device against slippage.

[0009] The coefficient of friction of the region to which the varnish is applied may be from 0.2 to 0.4. The coefficient of friction, which is within the range, is preferred from the point of view of the packaging assembly by the wrapping machine.

[0010] The varnish may be applied on a continuous area of not less than 0.5 cm ² . This configuration improves the anti-slip effect.

[0011] The package may be a rigid package having an opening and closing lid assembly, and the varnish may be applied to at least part of the lid assembly. With this configuration, the part functions as a slipping safety device when the user opens or closes the lid, which improves convenience.

[0012] The packaging may be soft packaging, and the varnish may be applied to at least a portion of each of two surfaces parallel to each other. In the case of soft packaging, applying lacquer on two surfaces parallel to each other improves the effect of preventing slippage.

[0013] A wrapping material may be additionally provided with which the whole package is wrapped. In this case, the remaining part of the wrapping material may prevent the package from falling when part of the wrapping material is removed to open the wrapping material.

[0014] The means for solving problems according to the present invention can be taken in combination as far as possible.

[Invention Results]

[0015] the Present invention allows to reduce the slipperiness of the surface of the package and improve convenience.

[DESCRIPTION OF EMBODIMENTS OF THE INVENTION]

[0017] An embodiment of the package of the present invention will be described referring to the drawings. The following embodiment is merely illustrative, and the technical scope of the present invention is not limited to the following aspects.

[0018] For example, one of the rigid box packaging, soft packaging, and various other packaging may be used as packaging. In the embodiment below, the case in which the tobacco product is placed will be described as an example. Tobacco products include a wrapped cigarette (filter cigarette or cigarette without a filter mouthpiece), a cigar, a thin cigar, an electronic cigarette, and smokeless tobacco (snuff or chewing tobacco).

[0019] Packaging Configuration

Figures 1 and 2 are perspective views of rigid boxed packaging (also simply referred to as “ packaging ” ) 1 according to an embodiment. Figure 1 illustrates the state with the lid closed, while Figure 2 illustrates the state with the lid open. Package 1 consists of a main body 2 and a lid unit 3 and has almost the shape of a parallelepiped. The lid assembly 3 is openable and closable around the hinge 4 in the upper portion of the rear surface of the main body 2.

[0020] It should be noted that, as the directions shown in FIG. 1, the surface provided with the hinge 4 to which the main body 2 and the lid assembly 3 are attached is supposed to be the rear surface of the package 1, and the direction that is reversed to the rear surface, it is assumed as the rear. The opposite surface is assumed as the front surface (front surface), and the direction that is facing the front surface is assumed as the front. A lid assembly 3 is provided, wherein the surface lying in the direction in which the product is to be located, is received through the opening opening of the main body 2, appearing at the time when the lid assembly 3 is open, is supposed to be the upper surface (upper surface), and its opposite surface is supposed to be the bottom surface. The directions of the upper and lower surfaces are assumed to be upward and downward, respectively. When the package 1 is viewed from the front surface, the left and right surfaces are supposed to be the left side surface and the right side surface, respectively.

[0021] As illustrated in FIG. 1, the package 1 is completely covered with the film 5 in the unopened state. The tear tape 6 is attached to the film 5 so as to run around the package 1 along the front surface, the left side surface, the back surface and the right side surface. The tear-off tape determines the position at which the tear-off tape 6 must be broken when the film 5 is opened, and is intended to improve the opening of the film 5. The user can clamp one end of the tear-off tape 6 and tear the film 5 along the tear-off tape 6. Figure 2 represents the open package 1. The top film is removed to expose the lid assembly 3 and the area around the lid assembly 3 of the main body 2. As illustrated in FIG. 2, a product 7 that is to be located which is a tobacco product wrapped in aluminized This paper is located in package 1.

[0022] The lacquer according to the present embodiment is applied to the front surface of the package 1. In figures 1 and 2, the varnished area 8 where the lacquer is applied is shaded (with hatching). Varnish can be applied to an arbitrary area, for example, by printing. It should be noted that the location of pre-determined information, such as the company name or company name, markings, and the like, can be printed below or above ink varnishing or the like. Varnish can be printed in layers. By changing the print pattern as described above, not only the film can be prevented from falling, but also the appearance or touch can be changed. For example, the range of representation of the brand image increases.

[0023] The lacquer according to the present embodiment is, for example, a water soluble lacquer containing a urethane resin (polyurethane) and water as main components. In the state in which the varnish is dried and cured after printing, the coefficient of friction with stainless steel is between 0.2 and 0.5. Since the friction coefficient can be increased by increasing the urethane resin content, the urethane resin content at which the friction coefficient after curing is approximately the specified value will be set. As described above, if the varnish is a varnish containing urethane resin and water as main components, the coefficient of friction in the application area can be changed without imprinting special markings or a special pattern. The lacquer can be colorless or can be colored by the addition of pigment.

[0024] According to the above-described package 1, the user's finger is delayed from slipping when the user opens or closes the lid assembly 3, and the usability is improved. By means of the varnish described above, package 1 is preferable from the point of view of universal design. It should be noted that the lacquer is preferably applied to a continuous area, as a rule, not less than 0.5 cm ² in order to prevent the finger from slipping off the lid assembly 3. In the case of, and when the varnish is applied to an area other than the lid assembly 3, such as a front surface, a back surface, a left side surface, or a right side surface, the varnish functions as a means to prevent slippage when the user handles the package.

[0025] It should be noted that the coefficient of friction is a value obtained by measuring the coefficient of friction with stainless steel packaging made of paper material with the above varnish applied over the entire surface, the load on which is estimated 200 g. The method for measuring the coefficient of friction will be described below. Figure 3 is a schematic view for explaining a method for measuring a coefficient of friction. In the present embodiment, the kinetic friction coefficient or the static friction coefficient is obtained by using the so-called tension type of the friction coefficient testing machine. FIG. 3 illustrates a dynamometer element 101, a stainless steel table 102, a test sample 103, which is a paper material on which a varnish is applied in accordance with the present embodiment, a sled 104, and a cable 105. The dynamometer 101 is connected to a sled 104 cable 105, and the slide 104 stretch in the direction of the arrow at a speed of 150 mm / min. It should be noted that the maximum load of the torque element 101 is 20 N. In contrast, test sample 103 is placed on a stainless steel table 102, and slide 104 is additionally located on the test sample 103. Stainless steel table 102 is made of austenitic SUS304 stainless steel (JIS G 4304 or JIS G 4305) containing nickel and chromium as main components, and the surface is smoothly treated. In test sample 103, the surface size in contact with the stainless steel table 102 is 63.5 mm x 63.5 mm, and the varnish is applied to the surface in contact with the stainless steel table 102. The sled 104 weighs 200 g. In accordance with the measurement conditions described above, the coefficient μ _{D of} kinetic friction is calculated using the kinetic force F _D (H) of friction when the carrier 104 is extended to a predetermined length after the offset of the plane of contact of the stainless steel table 102 with the subject sample 103, and the normal force F _P (H), generated by the mass of the sled 104, by the following expression:

μ _D = F _D / F _P.

The static friction coefficient μ _S is calculated using the maximum static friction force F ₀ (N) when an offset of the plane of contact of the table 102 of stainless steel with the test specimen 103 and the normal force F _P (H) generated by the mass of the slide 104 is generated, with the following expression:

μ _S = F ₀ / F _p .

[0026] The slippage between the package 1 and the film 5 is reduced. That is, in the state as in FIG. 2, where part of package 1 is wrapped with film 5, film 5 inhibits package 1 from falling. Especially if tobacco products, like contents, are reduced, which makes the package likely to be bent if the shrinkage in the film a wrap (close contact due to shrinking of the film) is not sufficient, or when carrying the package in a bag or pocket, the film is likely to fall off. If the film 5 disappears, the protection ability of the placed product in the case when the package 1 becomes wet decreases. The effect of delaying the aroma of the disposed product 7 from volatilization and the effect of the dust of crushed tobacco from falling from the inside decrease. Thus, the delay of the fall of the film 5 by means of varnish leads to an improvement in the ability to maintain the quality of the placed product 7.

[0027] The lacquer described above has a low gloss, a so-called devoid of gloss (matte) appearance, and has a wet touch. The design of package 1 can be improved by applying such a lacquer to package 1 as part of a drawing or marking. For example, the unification of the structure can be achieved by applying a varnish on the top surface or the bottom surface. In addition, it is possible to convey another sense of touch by changing the shape of the pattern or pattern of the pattern. It should be noted that it is desirable to cure the lacquer in order to have a touch that does not bring a feeling of unusualness on the finger after contact from a hygiene point of view or in such a way as not to convey a sense of discomfort to the user. Although an increase in the urethane resin content transmits such a touch, no problem is created as long as the friction coefficient is within the range described above.

[0028] In the case where the packaging is collected by a wrapping machine, failures may occur in processes such as feeding to form empty packaging and passing the formed packaging if the coefficient of friction is too high. Although the friction coefficient depends on the model of the wrapping machine, the packaging design, the assembly speed, and the like, the friction coefficient, more preferably, is from 0.2 to 0.4 during the box manufacturing process.

[0029] To prevent the film 5 from falling off, since the contact area between the film and the surface of the package is easily fixed in the case of a rigid package having a relatively high rigidity, the varnish is preferably applied to at least part of each of one or more surfaces from the front surface, the back surfaces and the like. In contrast, in the case of a soft package having a lower stiffness than a rigid package, since the shape is easily deformed by external force or the like, the contact area between the film and the surface of the package may not be ensured. For this reason, in a soft package, the lacquer is more preferably applied to at least part of each of two parallel surfaces, such as the front surface and the back surface of the parallelepiped, in order to prevent the film 5 from falling off. To obtain a sufficient effect of preventing slippage, the varnish preferably applied on a continuous area of about 0.5 cm ² .

[0030] Figures 4 and 5 illustrate an example in which a lacquer is applied to a portion of each of the front surface and the back surface of the soft package 1A. FIG. 4 is a perspective view of a soft package 1A viewed from one side (called the front side for convenience). FIG. 5 is a perspective view of a soft package 1A viewed from the opposite side (called the back side for convenience). The soft package 1A has a varnished area 8, which extends from the upper part to the lower part in the middle in the transverse direction of each of the front surface and the rear surface. Soft packaging with this configuration can be accepted. This allows for a sufficient contact area between the film and the surface of the package and allows for more reliable containment of the film from falling.

[0031] Other changes

For packaging, various paper materials or polymeric materials or the like can be used. For example, in the case of rigid packaging, paper material, such as cardboard or manila cardboard, is suitably used. The present invention, however, is not limited to this. For example, not only polymeric material, such as plastic, but any other material, such as metallic material, can be used as a material for packaging.

[0032] Also, when printing with ink or the like, the surface of the package may be embossed, flocked using a pile (short fiber), or the like. A lacquer sublayer or a region separate from the lacquer region may be subjected to the processes described above.

[0033] The film 5 is an example of a material in which the package 1 is wrapped. For example, a polymeric film, a laminate such as laminated paper and film, or laminated aluminized paper and film, or the like, can be used as a coating material. Specific examples of the polymer film include polypropylene (PP), polyethylene (PE), and cellophane.
