Embodiments of the package of the present invention will be described with reference to the drawings. The embodiments shown below are exemplified, and the technical scope of the present invention is not limited to the following aspects.

For example, the package can be packaged in a hard box, soft Packaging, or a variety of other packaging. In the following embodiments, the case of accommodating a cigarette product will be described as an example. Cigarette products include paper-rolled cigarettes (filter cigarettes, two-cut cigarettes (no filter)), cigars (rolled leaves), small cigars, electronic cigarettes, smokeless cigarettes (chewing tobacco, snuff), and the like.

<Composition of packaging>

Figs. 1 and 2 are perspective views of a hard case type package (hereinafter also referred to simply as "package") 1 of the embodiment. Fig. 1 shows the state of the closed lid, and Fig. 2 shows the state of the open lid. The package 1 has a substantially rectangular parallelepiped shape composed of the main body 2 and the lid portion 3. The lid portion 3 is formed to be openable and closable with the hinge 4 located on the upper portion of the back surface of the main body 2 as an axis.

Also, as shown in Fig. 1, the surface of the hinge 4 to which the main body 2 and the lid portion 3 are attached is provided as the back surface of the package 1, and the direction in which the back surface faces is rearward. Further, the surface on the opposite side of the back surface is set to the front side (front side), and the direction in which the front side faces is the front. Further, the surface of the lid portion 3 provided with the lid portion 3 in the direction in which the opening portion of the main body 2 which appears when the lid is opened is taken as the upper surface (top surface), and the surface on the opposite side is used as the bottom surface, and the upper surface and the bottom surface are oriented. The directions are up and down. In addition, the left and right surfaces when the package 1 is viewed from the front side are respectively set to the left side surface and the right side surface.

As shown in Fig. 1, the package 1 is in a state before opening, and the whole is covered with a film 5. The film 5 is adhered to a tear tape 6 around the front surface, the left side surface, the back surface, and the right side surface of the package 1 for one week. The opening tape is used to mark the position where the film 5 is torn at the time of opening, and the opening property of the film 5 is improved. The user grasps one end of the opening tape 6 to tear the film 5 along the opening tape 6. Figure 2 shows the opening The sealed package 1 removes the upper film and exposes the lid portion 3 and the body 2 around it. Moreover, as shown in FIG. 2, the inside of the package 1 accommodates the to-be-contained material 7 which wraps the goods with aluminum vapor-deposited paper.

The varnish of this embodiment is applied to the front side of the package 1. In the first and second figures, the varnish area 8 to which the varnish is applied is indicated by a hatched line (shaded portion). The varnish can be applied to any portion by, for example, printing. In addition, it is also possible to print a predetermined information or pattern, such as a brand or a company name, by ink or the like under the varnish. In addition, the varnish can be printed repeatedly. Thus, by changing the printed pattern, it is possible to prevent not only the peeling of the film but also the appearance or touch, such as the extent of the performance of the brand image.

The varnish of the present embodiment is, for example, a water-soluble varnish mainly composed of a polyurethane resin and water. After the varnish is printed, dried and hardened, the coefficient of friction with stainless steel is 0.2 to 0.5. Since the above friction coefficient can be increased by increasing the content of the urethane resin, the content (content percentage) of the urethane resin having a predetermined coefficient of friction after hardening is also determined. Thus, in the case of a varnish containing a polyurethane resin and water as a main component, it is possible to change the friction coefficient of the coating region without printing a special pattern and/or pattern. In addition, the varnish may be colorless or pigmented.

According to the package 1 as described above, when the user opens and closes the lid portion 3, the user's finger is prevented from slipping, and the ease of use is improved. Thus, according to the varnish, it is also preferable to use the package 1 from the viewpoint of universal design. Further, in order to suppress the slip of the finger to the lid portion 3, it is preferable to apply the varnish to a continuous area of approximately 0.5 cm ² or more. Further, when a varnish is applied to a surface other than the lid portion 3 such as the front surface, the back surface, the left side surface, or the right side surface, the user also functions as a slip-proof function when the user operates the package.

Further, the coefficient of friction was set to 200 g, and the value obtained by measuring the coefficient of friction of the paper of the package coated with the above varnish on the entire surface with respect to stainless steel was measured. The method of measuring the coefficient of friction will be described. Fig. 3 is a schematic view for explaining a method of measuring the coefficient of friction. In the present embodiment, a dynamic friction coefficient or a static friction coefficient is obtained using a so-called tensile type friction coefficient tester. Fig. 3 shows a load cell 101, a stainless steel stage 102, a test piece 103 belonging to the varnish-coated paper of the present embodiment, an SLED 104, and a wire 105. The load unit 101 is connected to the SLED 104 by a wire 105 which is stretched in the direction of the arrow at a speed of 150 mm/min. The maximum load of the load unit 101 is 20N. On the other hand, the test piece 103 is placed on the stainless steel stage 102, and the SLED 104 is placed on the test piece 103. The stainless steel stage 102 is made of SUS 304 (JIS G4304, JIS G4305) containing Worstian iron which mainly contains nickel and chromium, and the surface is smoothed. The surface of the test piece 103 in contact with the stainless steel stage 102 has a size of 63.5 mm × 63.5 mm, and a varnish is applied to the surface in contact with the stainless steel stage 102. The SLED 104 is 200 g. According to the above measurement conditions, the dynamic friction force F _D (N) when stretched by a predetermined length from the contact surface of the stainless steel stage 102 and the test piece 103 is used, and the quality is generated according to the quality of the SLED 104. The normal force F _P (N), and the following equation obtains the dynamic friction coefficient μ _D .

μ _D =F _D /F _P

Further, the maximum static friction force F ₀ (N) when the offset between the stainless steel stage 102 and the test piece 103 occurs and the normal force F _P (N) generated according to the mass of the SLED 104 are used, and the following formula is used to obtain the static friction. The coefficient μ _S .

μ _S =F ₀ /F _P

In addition, the degree of slippage is reduced even between the package 1 and the film 5. In other words, in a state in which the film 5 is covered with a portion of the package 1 in the second embodiment, the film 5 is prevented from falling off from the package 1. In particular, when the cigarette product belonging to the content is reduced and the package is easily bent, when the film package is not sufficiently shrunk (by the shrinkage of the film), it is carried in a bag or pocket. When the film is easy to fall off. When the film 5 is detached, if the package 1 is immersed in water, the protective properties of the contents are lowered. Further, the effect of suppressing the volatilization of the aroma of the contained article 7 and the effect of suppressing the powder of the shredded tobacco from being scattered from the inside are also reduced. Therefore, if the detachment of the film 5 is suppressed by the above varnish, it contributes to the improvement of the quality retention function of the article 7 to be stored.

The varnish described above is a so-called matte (flat hue) with a low gloss and a wet touch. The varnish as described above may also be applied to the package 1 as part of a pattern or pattern, thereby improving design. For example, varnish is applied to the top or bottom surface to achieve uniform design. In addition, different touches can be imparted by changing the shape or pattern of the coating. Further, the varnish is preferably one which is hygienic or does not cause an unpleasant feeling to the user, and does not leave an uncomfortable feeling to the finger after the contact. As long as there is no problem in the range of the above friction coefficient, when the content of the polyurethane resin is increased When it is over, it becomes a touch as described above.

When the package is combined by a packaging machine, if the coefficient of friction is too high, the steps of feeding the packaged bad material or the delivery of the package during the forming process may be hindered. It is also affected by the structure of the packaging machine or the structure of the packaging, the speed of the combination, etc., but in the box making step, the friction coefficient is preferably about 0.2 to 0.4.

In order to suppress the peeling of the film 5 and to provide a rigid package having relatively reliable rigidity, since it is easy to ensure the contact area between the film and the surface of the package, it is preferable to apply a varnish to at least a part of any of the front surface and the back surface. On the other hand, in the case of a flexible package having a lower rigidity than a rigid package, since the shape is easily deformed by an external force or the like, there is a concern that the contact area between the film and the surface of the package cannot be ensured. Therefore, in the flexible packaging, in order to suppress the peeling of the film 5, it is preferable that at least a part of each of the front and back sides of the parallel parallelepiped is coated with a varnish. Further, in order to obtain a sufficient anti-slip effect, it is preferred to apply a varnish to a continuous region of about 0.5 cm ² .

Fig. 4 and Fig. 5 show an example in which a varnish is applied to a part of each of the front surface and the back surface of the flexible package 1A. Fig. 4 is a perspective view of the flexible package 1A viewed from one side (hereinafter referred to as the front side for convenience of explanation). Fig. 5 is a perspective view of the flexible package 1A viewed from the opposite side (hereinafter referred to as the back side for convenience of explanation). The flexible package 1A has a varnish area 8 in the center in the left-right direction over the front and back sides. It is also possible to adopt the case of the flexible package constructed as described above. Thereby, the contact area of the film and the surface of the package can be sufficiently ensured, and the fall of the film can be suppressed more reliably.

<Other variants>

The packaging is capable of using paper or resin materials from a variety of industries. For example, in the case of a hard package, for example, a paper such as a card paper or Manila paper is suitably used, but is not limited thereto. For example, as for the material of the package, a resin material such as plastic may be used, and other materials such as a metal material may be used.

The surface of the package may be subjected to emboss processing, flocky processing using piles (short fibers), or the like, in addition to printing by ink or the like. The processing may also be applied to the underlying layer of the varnish or to a region different from the varnish region.

The film 5 is an example of a covering material in which the package 1 is packaged. For example, a polymer film, a laminated paper of paper and film, a laminated material of aluminum vapor deposited paper and a film of laminated film, or the like may be used as the covering material. Specific examples of the polymer film include polypropylene (PP), polyethylene (PE), cellophane, and the like.
