Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a product sample used in a vending machine.

[0002]

2. Description of the Related Art Usually, in a vending machine such as a cigarette, a sample of a product to be sold is displayed in a glass window of the vending machine. Then, the following two methods have been conventionally adopted as a method for manufacturing this sample. One is a method of printing a pattern on a tin plate and then bending it into a box shape. The other is assembling parts consisting of several kinds of plastic molded products into a box shape, and then forming a box shape on the surface. This is a method of attaching a printing film.

[0003]

In the former method described in the prior art, special equipment is required to bend the tin plate after printing to make it into a box shape, and the printing ink at the bent portion is lined up. There was a problem that it was cut into a shape.

Further, in the latter case, since a printing film is attached after assembling a molded article composed of several kinds of parts, there is a problem that it takes a lot of time and the production cost becomes high.

The present invention has been made in view of the above problems, and the object thereof is to easily assemble with one part and to maintain a good pattern surface even after the assembly. An object of the present invention is to provide a method of manufacturing a sample for a vending machine that can perform the above.

[0006]

In order to achieve the above object, a method for producing a sample for a vending machine according to the present invention comprises a crease and a crease by in-mold molding in which a pattern film layer is melt-integrated on the surface of a molding resin. It is characterized in that after forming a thin plate in a developed form of a sample with a hinge portion having a rounded shape provided on the surface side of the corner portion, the thin plate is bent at the hinge portion to form a box shape.

[0007]

In the method for manufacturing a sample for a vending machine according to the present invention, when a thin plate formed in a developed shape is bent at the hinge portion and assembled into a box shape, the elongation of the pattern film layer at the hinge portion is the outer rounded portion. It becomes a dispersed state.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.

1 and 2 are a front view and a rear view, respectively, showing a thin plate 1 for forming a sample of a cigarette. The spread thin plate 1 is formed by injection-molding polypropylene, and a pattern film layer is integrated on the surface by known in-mold molding. That is, a decorative pattern film layer made of the same material as the molding material is attached to a mold, and this is completely melted and integrated as a part of the molded product by the injection pressure and heat of the resin at the time of molding. ..

The thin plate 1 having a pattern film layer integrated on its surface has side panels 3 and 4 connected to both sides of the front panel 2 via hinge portions a and b, and a top panel on the upper side. 5 has a developed shape in which they are continuously provided via a hinge portion c. Then, as shown in FIG. 3, the cross-sectional shapes of these hinge portions a, b, c are rounded on the front surface side where the pattern film layer 7 is provided so as to surround the corner 6 which is a fold line formed on the back surface side. The shape has R. Further, as shown in FIG. 2, on the back surface side of the thin plate 1, ribs 8 and 9 to be fitted at the time of assembly are provided on both sides of the hinge portions a and b, and the side panels 3 and 4 and the top panel. Similar ribs 8 and 9 are also provided on the tip portion of 5 at positions corresponding to those at the time of assembly. In addition, one rib 8
Is bifurcated, and the other rib 9 is inserted and fitted between them. One rib 8 is tapered with respect to the other rib 9 so as not to easily come off in the fitted state.

The details of the hinge portion are shown in FIG. Here, the thickness of the molded product is 1 to 1 in terms of strength and bending.
The thickness d of the front panel 2 is 1.5 mm, and the thickness e of the side panels 3 and 4 and the top panel 5 (represented by the side panel 4 in the following description) is preferably about 2 mm.
Is 1.2 mm. The roundness R is formed outward with a curvature r having a radius of 1 mm, and is smoothly connected to the side panel 4 via a connecting portion having a curvature r ′ having a radius of 0.5 mm. The corner portion 6 to be a fold is formed at an obtuse angle, and the distance f from the corner portion 6 to the connecting portion of the side panel 4 is 0.5 to 0.8 mm. This distance f is 0.5
If it is less than 0.8 mm, the resin pressure at the time of molding is insufficient and the pattern film layer cannot be transferred well. The inclination angle α of the side panel 4 with respect to the front panel 2 is 12 to 20 °. It is preferable that the inclination angle α is large, but the distance g from the bottom surface of the front panel 2 to the tip of the side panel 4 is usually within a range of 5 mm or less because the elongation of the film during molding is restricted.

The above molding resin has a bending elastic modulus of 1
It is preferable to use one having a weight of 5000 kg / cm ² or less. That is, if the bending elastic modulus is more than this, there is a possibility of breaking when bent. Further, as the ink for the pattern film layer, it is preferable to use urethane-based or vinyl chloride-based ink so as not to be cracked when folded.

The thin plate 1 having the above-mentioned structure is fitted with the bending ribs 8 and 9 at the hinge portions a, b and c so as to be engaged with each other and locked, and the cigarette sample 1 as shown in FIGS.
0 is formed. Here, since the hinge portions a and b have a shape having a roundness R on the outside, as shown in FIG. 8, when the hinge portions a and b of the pattern film layer 7 are bent,
The extension at the portion corresponding to b is dispersed at the rounded portion R and is not concentrated at one location. Therefore, by using a soft ink for the pattern, the ink can follow the elongation of the pattern film layer 7, and the ink is prevented from cracking. In addition, since the hinge portion c has little bending, the ink does not crack.

FIGS. 9, 10 and 11 are a front view, a bottom view and a rear view showing a thin plate 11 of the second embodiment, respectively. This unfolded thin plate 11 is formed by the same method as that of the previous embodiment, the surface is integrally provided with a picture film layer, and the hinge portions a, b and c are shown in FIG.
And has a shape similar to that shown in FIG. And
The thin plate 11 of this embodiment has a pair of arm portions 13a and 14a on both side panels 13 and 14 on both sides of the front panel 12, one arm portion 13a having a boss hole 13b, and the other. A boss 14b is formed on the arm portion 14a.

By folding the thin plate 11 having the above-mentioned structure at its hinge portions a and b and pushing the boss 14b into the boss hole 13b and locking it, a cigarette sample 20 as shown in FIG. 12 is formed. In this case, the top panel 15 is inclined inward at the time of molding, and the side panels 13 and 14 are
Since it is partially connected at the boundary with the hinge part c
Even if the upper panel 15 is not bent, the upper panel 15 is inclined as shown in FIG. Then, as in the case of the previous embodiment, the ink of the pattern film layer is not cracked at the bent hinge portions a and b. Further, in the previous embodiment, since the ribs 8 and 9 are only engaged with each other, there is a risk that they will come off if an external force is applied, but in the present embodiment, the boss 14b and the boss hole 13b are present. It is firmly fixed with and does not come off.

FIGS. 13, 14 and 15 are a front view, a top view and a rear view, respectively, showing a thin plate 21 of the third embodiment. This developed thin plate 21 is formed by a method similar to that of the previous embodiment, the surface is integrally provided with a picture film layer, and the hinge portions a, b and c are shown in FIG.
And has a shape similar to that shown in FIG. In the thin plate 21 of this embodiment, the side panels 2 on both sides of the front panel 22 are provided.
3, 24 do not extend to the upper portion, but instead, upper side panels 26 and 27 are provided on both sides of the upper panel 25 via hinge portions a ′ and b ′, and the hinge portions a ′ and b ′ are also provided. The shape is similar to that shown in FIGS. 3 and 4. The side panels 23 and 24 have a pair of arm portions 23a and 24a, respectively, as in the second embodiment.
Is provided, and one arm portion 23a has a boss hole 23b.
And a boss 24b is formed on the other arm 24a. The upper side panels 26, 27 are provided with bosses 26a, 27a on the outer sides of the lower portions, and correspondingly, boss holes 23c, 24c are formed on the outer sides of the upper portions of the side panels 23, 24. ..

The thin plate 21 having the above-described structure is bent at its hinge portions a and b, and the boss 24b is pushed into the boss hole 23b to be locked, and the upper panel 25 is tilted inward at the hinge portion c to form the bosses 26a and 27a. By pushing and locking the boss holes 23c and 24c respectively, as shown in FIG.
A swatch 30 of tobacco is formed as shown in FIG. Also in this case, as in the case of the previous embodiment, the ink of the pattern film layer is not cracked at the bent hinge portions a, b, c, a ', b'. Further, in the second embodiment, when placed in an outdoor vending machine or the like, there is a risk that the molded product contracts due to solar heat and warpage occurs, causing the top panel 15 and the side panels 13 and 14 to open. However, in the present embodiment, the side panels 23, 24 and the upper side panels 26, 27 are firmly fixed to each other, so that there is no such fear.

FIGS. 17, 18 and 19 are a front view, a bottom view and a rear view showing a thin plate 31 of the fourth embodiment, respectively. This unfolded thin plate 31 is formed by a method similar to that of the previous embodiment, a pattern film layer is integrated on the surface, and hinge parts a, b, c are shown in FIGS. The shape is similar to that shown in FIG. The thin plate 31 of this embodiment is substantially the same as that of the second embodiment, but the configurations of the arms provided on the side panels 33 and 34 on both sides of the front panel 32 are different. That is, the lower arm portions 36, 3
7 is formed wide, and the upper arm portion 33a having the boss hole 33b and the upper arm portion 34a having the boss 34b and the arm portion 37 having the pair of bosses 37a than the arm portion 36 having the pair of boss holes 36a. Is making the person longer. further,
A pair of bosses 32 a is provided on the lower back side of the front panel 32. Also, the part where the contents of the cigarette can be seen is slightly recessed to give a three-dimensional effect.

The thin plate 31 having the above structure is bent at its hinge portions a and b, and the bosses 37a and 34b are pushed into the boss holes 36a and 33b and locked, thereby forming a cigarette sample 40 as shown in FIG. It In addition,
The point that the top panel 35 is preliminarily inclined is the same as in the case of the second embodiment. Even in this case, the ink of the pattern film layer is not cracked at the bent hinge portions a and b. In addition, the arm portions 37 and 34a are closer to the arm portion 3
Since it is longer than 6, 33a, the locking operation can be performed easily. Furthermore, since the arms 36 and 37 are wide and fixed at two places, the bent state of the side panels 33 and 34 is firmly maintained.

The cigarette sample 40 shown in FIG. 20 can be fixed to a predetermined position of the vending machine by using the mounting member 38 shown in FIG. That is,
The boss holes 38a of the mounting member 38 are fitted into a pair of bosses 32a provided on the lower back side of the front panel 32 to integrate the two as shown in FIG. 22, and the boss holes 38a are inserted into a slit of a vending machine to be fixed. ..

[0021]

The present invention, which is configured as described above, has the following effects.

By integrating the pattern film layer by in-mold molding and providing the hinge portion so that it can be bent after molding, a sample for a vending machine can be made with one part.

Since the hinge portion is formed to have a rounded shape on the surface side, the elongation of the pattern film layer outside the hinge portion is averaged when the hinge portion is bent, and the ink is not cracked. A good pattern surface can be maintained afterward.
