Description

  The present invention relates to a package.

  A varnish may be applied to the surface of a package for packaging products such as tobacco. As a technique for printing a varnish, not limited to a package, a technique for providing a mat portion and a gloss portion while improving friction resistance has been proposed (for example, Patent Document 1). Further, a technique has been proposed in which a water-wetting pattern does not appear even when wrapped with a film by providing a convex layer in which a varnish is printed in a convex shape (for example, Patent Document 2).

  A conventional varnish-coated package has a low surface friction coefficient of about 0.05 to 0.15. For example, it is easy to slip when the lid is opened or closed, or when the outside of the package is further wrapped with a film. May easily fall off.

  The present invention has been made in view of such problems, and it is an object of the present invention to reduce the ease of slipping of the package surface and improve convenience.

  In order to solve the above-described problems, a package according to the present invention is a package that accommodates tobacco products, and a region in which a water-soluble varnish mainly composed of urethane resin and water is applied to at least a part of the surface. including.

  By adopting a water-soluble varnish containing a urethane resin, it is possible to increase the coefficient of friction of the applied region. That is, the area where the varnish is applied functions as an anti-slip when the user handles the package, improving convenience.

  Further, the friction coefficient of the region where the varnish is applied may be 0.2 to 0.5 with respect to the stainless steel. If it is the range of such a friction coefficient, it is preferable as a slip prevention.

  Further, the friction coefficient in the region where the varnish is applied may be 0.2 to 0.4. When the coefficient of friction is particularly in such a range, it is preferable for assembling the package with a packaging machine.

Moreover, the varnish may be apply | coated to the continuous area | region of 0.5 cm < ² > or more. In this way, the anti-slip effect is improved.

  The package is a hard package having a lid that can be freely opened and closed, and the varnish may be applied to at least a part of the lid. If it does in this way, when a user opens and closes a lid, it will function as a slipper and will improve convenience.

  The package is a soft package, and the varnish may be applied to at least a part of each of two parallel surfaces. In the case of a soft package, the effect of preventing slipping is improved when varnish is applied to two parallel surfaces.

  Moreover, you may make it further provide the coating | covering material which coat | covers the whole package. In such a case, when a part of the covering material is removed and opened, it is possible to prevent the remaining covering material from falling out of the package.

  Further, means for solving the problems in the present invention can be employed in combination as much as possible.

  According to the present invention, the ease of sliding on the package surface can be reduced and the convenience can be improved.

  An embodiment of a package according to the present invention will be described with reference to the drawings. The embodiment shown below is an exemplification, and the technical scope of the present invention is not limited to the following aspect.

  For example, a hard box type package, a soft package, and other various packages can be used as the package. In the following embodiment, a case where tobacco products are accommodated will be described as an example. Cigarette products include cigarettes (filter cigarettes, double-cut cigarettes (without filters)), cigars (cigars), cigarillos, electronic cigarettes, smokeless cigarettes (bite cigarettes, cigarettes), and the like.

<Package structure>
1 and 2 are perspective views of a hard box type package (also simply referred to as “package”) 1 according to the embodiment. FIG. 1 shows a state where the lid is closed, and FIG. 2 shows a state where the lid is opened. The package 1 has a substantially rectangular parallelepiped shape composed of a main body 2 and a lid portion 3. The lid 3 is openable and closable around the hinge 4 at the upper back of the main body 2.

  As shown in FIG. 1, the surface on which the hinge 4 to which the main body 2 and the lid portion 3 are connected is provided as the back surface of the package 1, and the direction in which the back surface faces is the rear. Also, the opposite side is the front (front), and the direction in which the front is facing is the front. Moreover, the cover part 3 is provided, the surface in the direction of taking out the contents from the opening of the main body 2 that appears when the cover is opened is the upper surface (top surface), the opposite surface is the bottom surface, and the direction in which the upper surface and the bottom surface face each other Top and bottom. Further, the left and right surfaces when the package 1 is viewed from the front are defined as a left side surface and a right side surface, respectively.

  As shown in FIG. 1, the package 1 is entirely covered with a film 5 in a state before opening. An unsealing tape (tea tape) 6 is attached to the film 5 so as to go around the front, left side, back, and right side of the package 1. The opening tape defines a position to be torn when the film 5 is opened, and improves the opening property of the film 5. The user can pick one end of the opening tape 6 and tear the film 5 along the opening tape 6. FIG. 2 shows the package 1 after opening, the upper film is removed, and the lid 3 and the surrounding main body 2 are exposed. Further, as shown in FIG. 2, an object 7 in which a tobacco product is packaged with aluminum vapor-deposited paper is accommodated in the package 1.

  A varnish according to this embodiment is applied to the front surface of the package 1. 1 and 2, the varnish region 8 to which the varnish is applied is hatched. The varnish can be applied to any part by printing, for example. In addition, under the varnish or above, predetermined information such as brands and company names, patterns, and the like may be printed with ink or the like. Further, the varnish may be overprinted. By changing the printing pattern in this way, not only can the film be prevented from falling off, but also the appearance and feel can be changed. For example, the range of expression of the brand image is expanded.

  The varnish according to the present embodiment is, for example, a water-soluble varnish mainly composed of a urethane resin (polyurethane) and water. Moreover, in the state which dried and hardened | cured after printing of the varnish, a friction coefficient with stainless steel will be 0.2-0.5. In addition, since said friction coefficient can be raised by increasing content of a urethane resin, content (content ratio) of the urethane resin from which the friction coefficient after hardening becomes a predetermined grade is also determined. Thus, if it is a varnish which has a urethane resin and water as a main component, the friction coefficient of the apply | coated area | region can be changed, without printing a special pattern or pattern. The varnish may be colorless or colored by including a pigment.

According to such a package 1, when a user opens and closes the cover part 3, it is suppressed that a user's finger | toe slips and usability improves. Thus, according to the varnish, the package 1 is preferable from the viewpoint of universal design. In addition, in order to suppress the slip of the finger with respect to the cover part 3, it is preferable to apply varnish to a continuous area of approximately 0.5 cm ² or more. Further, when the varnish is applied to a portion other than the lid 3 such as the front surface, the back surface, the left side surface, or the right side surface, it functions as a slipper when the user handles the package.

The friction coefficient is a value obtained by measuring the friction coefficient of a paper material of a package in which the load is 200 g and the entire surface is coated with the varnish with respect to stainless steel. Here, a method for measuring the friction coefficient will be described. FIG. 3 is a schematic diagram for explaining a method of measuring a friction coefficient. In this embodiment, a dynamic friction coefficient or a static friction coefficient is obtained using a so-called tension type friction coefficient testing machine. FIG. 3 shows a load cell 101, a stainless steel table 102, a test piece 103 which is a paper material coated with a varnish according to the present embodiment, an SLED 104, and a wire 105. The load cell 101 is connected to the SLED 104 by a wire 105, and the SLED 104 is pulled in the direction of the arrow at a speed of 150 mm / min. The load cell 101 has a maximum load of 20N. On the other hand, a test piece 103 is placed on the stainless steel table 102, and an SLED 104 is further placed on the test piece 103. The stainless steel table 102 is made of austenitic SUS304 (JIS G4304, JIS G4305) containing nickel and chromium as main components, and the surface thereof is smoothed. The size of the surface of the test piece 103 that contacts the stainless steel table 102 is 63.5 mm × 63.5 mm, and the surface that contacts the stainless steel table 102 is coated with varnish. The SLED 104 is 200 g. Under the measurement conditions as described above, it is generated by the dynamic friction force F _D (N) when the contact surface between the stainless steel table 102 and the test piece 103 is displaced and then pulled by a predetermined length, and the mass of the SLED 104. Using the normal force F _P (N), the dynamic friction coefficient μ _D is obtained by the following equation.
μ _D = F _D / _FP
Further, the static friction coefficient μ _S is calculated using the maximum static friction force F ₀ (N) when the deviation between the stainless steel table 102 and the test piece 103 occurs and the normal force F _P (N) generated by the mass of the SLED 104. It is calculated by the following formula.
μ _S = F ₀ / _FP

  Also, the ease of sliding between the package 1 and the film 5 is reduced. That is, in the state as shown in FIG. 2 where a part of the package 1 is covered with the film 5, the film 5 is prevented from falling off the package 1. In particular, when the content of tobacco products is reduced and the package is easily bent, the film is easy to be removed when shrinking in film packaging (adhesion due to film shrinkage) is insufficient, or when it is carried in a bag or pocket. . Here, when the film 5 falls off, the protection performance of the object to be stored in the case where the package 1 is wet with water is deteriorated. Moreover, the effect which suppresses volatilization of the flavor of the to-be-contained thing 7 and the effect which suppresses that the powder of tobacco tobacco spills from the inside will also be reduced. Therefore, if the falling of the film 5 is suppressed by the varnish, the quality retention performance of the object 7 is improved.

  Moreover, said varnish is what is called matte (matte tone) with low gloss, and has a moist touch. Such a varnish may be applied to the package 1 as a part of a design or a pattern to improve design. For example, varnish can be applied to the top surface or the bottom surface to unify the design. Also, different tactile sensations can be given by changing the shape and pattern to be applied. In addition, it is desirable for the varnish to have a tactile sensation that does not leave a sense of incongruity to the finger after contact so as not to give discomfort to the user for hygiene purposes. When the content of the urethane resin is increased, such a tactile sensation is obtained.

  Further, when assembling a package with a packaging machine, if the coefficient of friction is too high, there may be obstacles in the process of feeding out the package blank molding or delivering the package in the middle of molding. Although it is influenced by the type of packaging machine, the structure of the package, the assembling speed, etc., in the box making process, the friction coefficient is more preferably about 0.2 to 0.4.

In addition, in order to prevent the film 5 from falling off, in the case of a hard package having a relatively firm rigidity, it is easy to secure a contact area between the film and the surface of the package. It is preferable to apply varnish to at least a part. On the other hand, in the case of a soft package having a lower rigidity than that of a hard package, the shape is easily deformed by an external force or the like, so there is a possibility that the contact area between the film and the package surface cannot be secured. Therefore, in the soft package, in order to prevent the film 5 from falling off, it is more preferable to apply varnish to each of at least a part of two parallel surfaces of the rectangular parallelepiped like the front surface and the back surface. In order to obtain a sufficient anti-slip effect, it is preferable that varnish is applied to a continuous region of about 0.5 cm ² .

  4 and 5 show an example in which varnish is applied to a part of each of the front and back surfaces of the soft package 1A. FIG. 4 is a perspective view of the soft package 1A viewed from one side (for convenience, the front side). FIG. 5 is a perspective view of the soft package 1A as viewed from the opposite side (for convenience, the back side). The soft package 1A has a varnish region 8 in the center in the left-right direction across the top and bottom of the front and back. You may make it employ | adopt the case of the software package of such a structure. As a result, a sufficient contact area between the film and the surface of the package can be secured, and the falling of the film can be more reliably suppressed.

<Other variations>
Various paper materials and resin materials can be used for the package. For example, in the case of a hard package, a paper material such as card paper or Manila cardboard is preferably used, but is not limited thereto. For example, as a material of the package, other materials such as a metal material as well as a resin material such as plastic may be used.

  In addition to printing with ink or the like, the surface of the package may be subjected to embossing, flocking using pile (short fibers), or the like. These processes may be applied to the lower layer of the varnish, or may be applied to a region separated from the region of the varnish.

  The film 5 is an example of a covering material that wraps the package 1. As the covering material, for example, a laminated material such as a polymer film, a paper-film bonding paper, an aluminum vapor-deposited paper and a film bonding paper, or the like may be used. Specific examples of the polymer film include polypropylene (PP), polyethylene (PE), cellophane, and the like.
