Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a shrink-wrapping method for articles, and more specifically to a shrink-wrapping method that is optimal for transporting and displaying articles. To provide a shrink-wrapping method for articles having a completely new structure, which is less likely to fall apart and can be packaged very simply with a small amount of film.

Conventionally, as shown in FIG. 8A, only the articles T are assembled and shrink-wrapped with a shrinkable film 12, or as shown in the figure, the articles T are placed on a mount 13 and then wrapped in the film 12. In addition, as shown in FIG.

However, placing the items on a flat surface and shrink-wrapping them as shown in A and A in the figure is difficult due to the movement and dispersion of the items. There was a risk that the film sandwiched between the items would be torn, and since the film had to be torn to display the item, the item would fall apart, which would be extremely inconvenient for display. Furthermore, in the case shown in Figure C, packaging is difficult because the film goes all the way to the bottom of the tray 14, and there is also the disadvantage that a large amount of the film at the bottom must be used.

The present invention focuses on these points and develops a packaging method that is completely different from the conventional packaging method 15, so that the packaging film will not be torn during transportation and there will be no variation in the products when displayed. In addition, it is a shrink-wrapping method for products that uses less film, makes the packaging work easier, and allows for accurate packaging.The features of Somao are that it consists of a bottom plate and both side plates, and that the front and back edges have a After pasting a heat-shrinkable film on both sides of the tray so as to cover the upper surface of the opening of the tray formed with the notch, items are stored into the tray through the openings on both sides of the tray, and then the notch 25 is The front plate and the back plate formed by the process are bent inward, and both end face plates of both side plates are bent to the outside of the front plate and the back plate to integrate them.
Further, in this state, the film is shrink-wrapped by hot air.

The specific packaging method is shown in the drawing below.
An explanation will be given according to an example. First, as shown in FIG. 1, a tray 4 made of a cardboard box is prepared, which is made up of a bottom plate 1 and side plates 2, 2', and has notches 3a, 3b, 3c, and 3d formed at four locations on both longitudinal edges of the front and rear sides. do.

35 Next, as shown in FIG. 2, glue both side edges of the heat-shrinkable film 5 to the approximately central sides of the side plates 2 and 2' of the tray 4 so as to cover the top surface of the opening of the tray 4 with glue 15. I will wear it.

Thereafter, the articles 7 are stored and placed on the bottom plate 1 of the tray 4 through the openings 6, 6' on both sides in the longitudinal direction of the tray 4. (See Figure 3) Next, after storing the items 7..., the front plate 8 and the back plate 9 formed by the notches 3a, 3b, 3c, and 3d are inserted through the notches 10. As shown in Fig. 4, both end plates 2a of the side plates 2 and 2' are bent and raised in the internal direction, and then similarly formed by the cut portions.
.
The inner surface is brought into contact with 1 and integrated.

(See FIG. 5) When hot air is applied to this form, the heat-shrinkable film 5 shrinks, and a packaging form in which the article 7 is shrink-wrapped with the film 5 as shown in FIG. 6 can be obtained.

Therefore, even when items packaged in this manner are stacked during transportation, there is little risk of the film 5 being torn because they are stacked together via the tray 4, and the items will not fall apart when displayed, making them ideal for display. It has an exceptional effect. In this embodiment, the end plates of both side plates are attached to the front plate and the back plate integrally with an adhesive, but in addition to this, the end plates of both side plates are attached together with adhesive or staples. It is also possible to do so, and the means to do so are not limited in any way.

Furthermore, the means for attaching the film to the tray is not limited in any way. Next, FIG. 7 shows an example in which a tray 1 having the same height as the item 7 is used, and in this case, a heat-shrinkable film 5 is used.
The end portion 5' is bent and heat-sealed to both end face plates 2 & la 2b, and then the whole is shrink-wrapped using hot air. This embodiment has the advantage that handling during stacking and transportation is further simplified. Note that the shape, size, etc. of the tray are by no means limited to those in the above embodiment. As described above, the present invention involves attaching both side edges of a heat-shrinkable film to the side surfaces of a tray with openings on both sides, and then storing and placing articles into the tray through the openings on both sides. Since the opening is closed and the shrinkable film is shrunk using hot air for shrink wrapping, the film does not cover the entire tray, so the amount of film used is very small, and when the tray is stacked and transported, the film is Since there is only contact between the film and the tray, there is no tearing of the film, allowing for safe transportation.In addition, since the items are stored and placed on the tray during display, the items do not fall apart, making the display extremely effective. Furthermore, the packaging operation is extremely easy and inexpensive, and the packaging operation efficiency can be significantly improved, which has excellent practical effects.
