Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) This invention relates to a three-dimensional decorative tool made of, for example, a resin film, for decorating a storefront or the like.

(Prior Art) Many common store decorations include, for example, flowers that can be relatively easily formed with a three-dimensional effect by overlapping a plurality of resin films. However, it is difficult to create a three-dimensional effect with products shaped like fruits, etc., and manufacturing a product with a three-dimensional effect increases the number of man-hours and makes the product expensive. It was difficult to provide a suitable and inexpensive product.

(Problems that the invention aims to solve) As mentioned above, common three-dimensional decorations include flowers and the like made by overlapping multiple resin films, but those in the shape of fruits, etc. require more man-hours to manufacture. However, there were circumstances in which we were unable to provide inexpensive products.

This invention was made in view of the above-mentioned circumstances, and aims to provide a three-dimensional decorative tool that can be manufactured with fewer man-hours and has a three-dimensional appearance.

[Structure of the idea]

(Means and effects for solving the problem) This invention combines one side body and the other side body in a bag shape to form a main body, and provides a laminated sheet body on the outer surface of this main body, and the above-mentioned A plurality of filling decoration parts are provided between the main body and the sheet body, and a communication path is provided to communicate these adjacent filling decoration parts with each other, so that the main body is filled with gas and expanded, and the outside is filled with gas. With the filling decoration part protruding from the
To provide an inexpensive three-dimensional decorative tool that has a three-dimensional appearance and can be manufactured with a small number of man-hours.

(Embodiment) An embodiment of this invention will be described with reference to FIGS. 1 to 4.

For example, the main body 1 of the three-dimensional ornament is made of a resin film and has the outline shape of a bunch of grapes, and the edges 4 of the one side body 2 and the other side body 3 are heat-welded, for example, as shown in FIG. It is combined into an airtight bag by A first filling port 5 is provided in the branch portion of the joining edge 4 of the main body 1 formed in the shape of a bunch of grapes, so that the main body 1 can be filled with air as a gas.

Further, a sheet body 6 made of resin similar to the main body is bonded to the outside of the one side body 2 and the other side body 3 by heat welding over the entire surface thereof.

For example, one side body 2 and the corresponding sheet body 6
The coupling structure is constructed as shown in FIG. Both the one side body 2 and the sheet body 6 have an edge 4 shaped like the outline of a bunch of grapes that is heat welded.

Along with this welding of the edge 4, a plurality of circular frame-shaped welded parts 7 are provided within the range surrounded by the edge 4 of the one side body 2 and the sheet body 6.

A filling decorative portion 8 is formed between the one side body 2 and the sheet body 6 by being surrounded by the welded portions 7 of each other.
is configured. The filling decoration parts 8 adjacent to each other are provided with communicating passages 9 through which air can pass. That is, all the filling decoration parts 8 provided between the one side body 2 and the sheet body 6 are communicated with each other through this communication path 9.

and the one side body 2 formed in the shape of a bunch of grapes.
The two communication passages 9 located near the branch portions 11 of the sheet body 6 are provided with second filling ports 10 for supplying air as a gas from the outside.

Here, the structure of the other side body 3 and the sheet body 6 coupled to the other side body 3 is the same as the coupling structure of the one side body 2 and the corresponding sheet body 6, so the explanation is omitted. do.

The three-dimensional decoration device configured in this way has the above-mentioned first feature.
By supplying gaseous air from the filling port 5 in the direction of arrow A shown in FIG. 1, the main body 1 is expanded in the direction of arrow B. In addition, the second filling port 10
Air is supplied as a gas in the direction of arrow C from , and is filled into all the filling decoration parts 8 through the communication path 9, so that the filling decoration parts 8 are expanded so as to protrude from the outer surface of the main body 1. be done.

With this configuration, when the main body 1 and the filling decorative portion 8 are filled with air, the appearance is as shown in FIG. 3. The expansion of the main body 1 constitutes the volume of the grape bunch in appearance, and the filling decoration part 8 protrudes from the outer surface of the main body 1, thereby increasing the protrusion of the grains located on the outside of the grape bunch. constitutes the state.

In other words, the four-layer structure consisting of the one side body 2 and the sheet body 6 provided on the outside thereof, and the other side body 3 and the sheet body 6 provided on the outside thereof, provides a three-dimensional appearance as described above. I can do it.

Further, the three-dimensional ornament configured as described above is manufactured, for example, as follows.

First, the sheet body 6 is laminated on the outer surface of each of the one side body 2 and the other side body 3, which are in the state of separate sheets, and are joined by the welding structure shown in FIG. 2 to form the filled decoration part. 8 is formed. Moreover, the excess portion on the outside of the edge 4 in the shape of a bunch of grapes is melted and cut off at the same time as the welding described above. Next, manufacturing is completed by welding only the edges 4 of the one side body 2 and the other side body 3 with their inner surfaces facing each other. By manufacturing in this way, in order to form the filling decoration part 8, a three-dimensional fruit shape can be created by simply repeating the heat welding process of the resin film without requiring any special machine or process. A structure that can express the appearance can be obtained.

Note that the positions where the first and second filling ports 5 and 10 are provided are not limited to those described above. For example, as shown in FIG. 4, the second filling port 10 is provided only on one side of the body 2, the other side of the body 3 is closed, and the second filling port 10 is provided on the lower tip side of the grape cluster-shaped body 1. Also included are those in which a filling passage 13 is provided that communicates from the filling decoration part 8 on the one side body 2 side to the filling decoration part 12 on the other side body 3 side. According to such a structure, only one first and second filling ports 5 and 10 are required, and it is only necessary to supply air as a gas in the directions of arrows D and E in FIG. The effort required for decoration can be reduced.
Further, the object to be imitated is not limited to the above-mentioned bunch of grapes, but may be any object that can express a three-dimensional appearance by providing the filling decoration part 8 on the outside of the main body 1. Furthermore, in the above embodiments, the materials and connection structures of each part are not limited to those described above. For example, although the one side body 2 and the sheet body 6 are bonded by heat welding, the present invention is not limited to this, and bonding by adhesive or the like may be used.

[Effect of idea]

As explained above, according to this invention, there is a main body that is formed into a bag shape and is expanded by being filled with gas, and a filling that is provided on the outside of the main body and expands so as to protrude outward. The decoration part allows for a three-dimensional imitation, and since it is constructed only by joining sheet-like members to each other, it is possible to provide an inexpensive three-dimensional decorative tool with fewer manufacturing steps.
