Description

[Detailed description of the invention] Coin packaging method and plastic film used therein This invention relates to a coin packaging method and plastic film used therein. This paper relates to a mounting method and the plastic film used therefor.

U.S. Patent No. 3,491,507 uses heat-shrinkable material to wrap coins. It has been proposed that this heat-shrinkable material wraps around a group of coin cylinders stacked in a line. It is something to do. At this time, the heat-shrinkable material is heated over the entire length of the coin cylinders. and is tightly engaged with the circumferential surface of the cylinder group. The packaging obtained in this way is heat shrinkable. The material is easily torn at the ends of the coin cylinders, and in addition, e.g. It is difficult to print enough to display the financial period of banks, etc. Na This is because if the heat-shrinkable material shrinks, the print will be distorted. Also good The disadvantage is that the wrapped packaging is hard and inflexible, making it difficult to open.

This invention facilitates packaging and eliminates the above-mentioned drawbacks of the prior art. The purpose is to overcome.

Objects and advantages of the invention are further set forth in the description below, and more. It is something that will be revealed.

In this invention, in order to achieve the above-mentioned object, a plastic material frame is used. Coin cylinders are formed by placing the film band so that its ends protrude from the ends of the coin cylinders. The film is heated near the ends of the cylinder group to heat the film. It is made to contract at the end of the cylinder group.

The invention further provides a film of plastic material used for packaging as described above. The ends of the film strip have greater heat absorption than the middle, and when heated The ends absorb heat and contract more quickly than the middle.

The accompanying drawings constitute a part of this specification and, together with the description, provide details of the invention. This is an explanation. In the figure, FIG. 1 shows the code for the first step of the method of this invention. Side view showing the columns of the Inn; Figure 2 shows the next step, where the film is heated at its edges for shrinkage. Ori, Figure 3 is a perspective view showing the entire package; FIG. 4 is a plan view showing a part of the plastic film strip of the present invention.

Figure 5 is a cross-sectional view of a printed film and Figure 6 is a diagram showing the manufacture of such a film. It is a side view which shows a process.

Embodiments will be described below with reference to figures.

In Figures 1 to 3, the film strip 11 of plastic material overlaps the coins in a line. It is wrapped around the cylinder group 10. This film is made of polyethylene or polypropylene. It does not need to be made of materials commonly used in conventional packaging, such as glass. This envelope has a group of cylinders Support it between the blocks 12 and roll it in the direction shown by the arrow 13. Wrap a suitable length of lume belt around this. The width of the cylinder group is its end 14 It is assumed that the cylinders protrude from the ends of the cylinder group 10.

Next, in the procedure shown in FIG. heat and cause contraction. In FIG. 2, the heating area is limited by the heating means 15. It is established. An example of such heating means is electric radiation, which blows hot air at the ends of the cylinders. A device equipped with a radiation heater or nozzle is used.

During heating, the cylinders wrapped in the film strip are rotated. This result is shown in Figure 3. It becomes like this. That is, as a result of heating the plastic, the end 15 becomes the end of the group of cylinders of the coin. 15.

When implementing the method of the present invention, if there is any printing, However, it does not become distorted.

This is because the middle area between the limited edges that are locally heated in packaging is not heated at all. This is because there is no shrinkage φ on the cylinder group.

The coin packaging thus obtained is very easy to open.

Moreover, it is safe and can withstand rough handling when transported in a large bag or box. be. However, if a perforation line 16 is formed in the center of the film, it becomes even easier to open. . In other words, the perforation line makes it easy to open the package from the center, and the film strip is cylindrical. Since the coins do not shrink into clusters, it is easy to remove the coins inside by cutting the package in half along this perforation line. It comes out.

Now, according to the present invention, a film for carrying out the above-described method is shown in FIG. It is shaped like this. Materials used for packaging include polyethylene and polypropylene. You can use what you normally use. Its end 17, for example a 5-7mm wide part is formed to be more endothermic than its intermediate portion 18. In other words, add an endothermic material to this end. It is embedded or coated in the portion 17. Such endothermic materials include metal or It is also possible to use a pigment containing a metal oxide pigment. In addition to this, or Alternatively, the end portion 17 may be made opaque by applying a dark color or the like. Middle part 18 may be printed to provide desired information. The width of the end 17 is the width of the film strip. Adjust so that it protrudes from the center of the column group and covers the latter end. do. The end 17 is more endothermic than the 18 force, so heating the end will cause the end to is heated more quickly and the middle section 18 receives less heating, while the end section 18 Rapid contractions occur. As shown in Figure 3, the end 17 is placed on the end of the cylinder group. It can be bent about 3 to 51 times. When this state is reached, immediately stop the heat radiation and cast a shadow on the middle part 18. Make sure you don't get too close.

Preferably the plastic film strip is transparent and replaced with a coin inside the package. to prevent fraudulent acts of inserting iron wand shears or iron rods. In other words, if you make it transparent, you can break the packaging. The contents can be visually inspected from the outside.

The films can also be laminated as shown in FIG. That is, one side of the inner layer 19]2 is printed as indicated by line 20 and this side is covered with a transparent outer layer 21. Also The inner layer 19 may also be made transparent for the reasons mentioned above, but it is not necessarily necessary to do so. isn't it. When wrapping the cylinder group with a film, printing is performed with the outer layer 21 on the outside. Prevent it from being damaged or worn out.

The arrangement shown in Fig. 5 can be further advanced to the arrangement shown in Fig. 6. Inside and outside M19.21 Before combining the films that make up the film, the inner film is pre-stretched to form a laminated film. Make the lume curve. As a result, when packaging the product, a film band or a coin circle is used. It wraps around the pillars well and makes packaging easier.
