Abstract

PURPOSE:To allow the production of the megaphones which are entirely different in appearance by sticking shrink films having many kinds of designs to the megaphone bodies according to purposes of use without changing the megaphone body. CONSTITUTION:The megaphone bodies 1 and the shrink films 2, 2' are previously produced respectively discretely and in a required number. The films 2, 2' shrink and adhere tightly to the body 1 when the films 2, 2' are put on the entire surface 1a of the body 1 and are heated from the outside. The designs 3a, characters 3b and colors 3c stuck to the films 2 2' are then immediately produced on the entire surface of the megaphone. The same bodies 1 can be used by easily sticking the films 2, 2' of the various different designs thereto. Then, the designs of the megaphones are easily changed simply by changing the films 2, 2' without entirely changing the megaphone bodies 1 of a relatively high cost. The cost of production is thus reduced. A user is also able to enjoy himself by removing the films 2, 2' from the megaphone body 1 after use and making his own design on the surface of such body 1.

Description

[Detailed description of the invention] (Industrial application field) This invention relates to a megaphone and its manufacturing method.

(Conventional technology) Megaphones, which are easy to use as public address equipment, have traditionally been used to support sports, events, elections, etc., but conventional megaphones have shapes on their entire surface that make a special impression on the public. There were no cases where each letter was decorated with one color.

(Problems to be Solved by the Invention) As described above, conventional megaphones merely have a loudspeaker effect.

However, in recent years, sports support and advertising activities have required not only audio appeals but also the use of colorful tools and visual appeal. Therefore, a megaphone with only a single color applied to its surface or with a patch partially pasted will not satisfy people (as a result, the effectiveness of support and advertising will not be fully demonstrated).

The present invention has been made in view of the above points, and its purpose is to provide a shrink film with animal designs, letters, or colors applied to substantially the entire surface of the megaphone body in accordance with the purpose of use. To provide a megaphone that sufficiently attracts people's eyes by covering it with a wafer, and a method for manufacturing the same.

(Means for Solving the Problems of the Invention) As shown in FIGS. 1 to 4 of the embodiment drawings, the first aspect of the present invention is to provide a substantially entire surface 1a of a hollow truncated conical megaphone body 1. , figure 3
This is a megaphone made of a shrink film 2,2'' printed with letters 3a, 3b, colors 30, etc.

Further, the second invention provides a megaphone body 1 having a hollow truncated cone shape and a figure 3a whose size corresponds to the megaphone body 1.
, characters 3b, colors 30, etc. are separately produced, and then the shrink films 2 are applied to substantially the entire surface 1a of the megaphone body 1.
, 2. This is a method for manufacturing a megaphone.

Further, in the second invention, there is provided a method of manufacturing a megaphone, in which various types of shrink films 2.2° printed with figures 3a, letters 3b, colors 30, etc. are manufactured depending on the purpose of use of the megaphone.

(Function) In the first invention, substantially the entire surface 1a of the megaphone body 1 is printed with, for example, a curve (carp) figure 3a, which is the abbreviation of professional baseball's Hiroshima Curve Team, the letters CARP 3b, and a red color 3C. When a megaphone covered with a shrink film 2.2'' is used at a stadium or the like, the appearance of the megaphone attracts people's attention and the effect of cheering can be further increased.

In the second invention, the megaphone main body 1 and the shrink films 2, 2' corresponding in size to the megaphone main body 1 are manufactured separately, and the shrink films 2, 2' are attached to the megaphone main body 1. You can make many types of shrink films 2, 2° with different shapes, letters, etc. depending on the purpose of use, and if you make many identical megaphone bodies, you can use different types of shrink films 2, 2° as needed. The megaphone main body 1 having the same shape can be used in a variety of ways, resulting in low cost.

(Example) Embodiments of the present invention will be described based on the drawings.

3 is the main body of the megaphone, which is made of synthetic resin and shaped like a hollow truncated cone. The dimensions of the megaphone body L are length 1.
It is indicated by the diameter of the large diameter and the diameter d of the small diameter.

Reference numeral 2 denotes a shrink film, which is formed from a thin film of synthetic resin into a cylindrical or hollow truncated cone of 2°. Its dimensions are 1°, which is slightly longer than 1 in length, and D, which is slightly larger than D in its major diameter. Therefore, shrink film 2
, 2° can be placed over the entire surface 1a of the megaphone body 1.

In addition, the shrink film 2, 2' has a carp shape on its surface depending on the purpose of use of the megaphone, for example, in the case of cheering on a curveball in professional baseball, as shown in Figure 2.
3b and the fabric is colored 3c in red. Alternatively, if the purpose is to attract customers when the store opens, the store's symbol mark, the popular animal panda shape, and the store name can be attached.

Next, as a manufacturing method, the required number of megaphone bodies 1 and shrink films 2, 2' are manufactured separately.
A shrink film 2. is applied to the entire surface 1a of the megaphone body 1.
Shrink film 2 when heated from the outside with 2°
, 2'' shrinks and comes into close contact with the megaphone body 1, and a figure 3 is immediately attached to the shrink film 2, 2'' on the entire surface of the megaphone.
a, a character 3b, and a color 3c are displayed. Further, shrink films 2, 2' with various designs can be easily attached and used on the same megaphone main body 1. Therefore, the design of the megaphone can be easily changed by simply changing the shrink film 2, 2 without having to completely change the megaphone body, which is relatively expensive. You can also enjoy removing the shrink film 2, 2 degrees from the megaphone body 1 and creating your own desired design on the surface of the megaphone body 1.

(Effects of the Invention) According to the present invention, it is possible to easily create megaphones with completely different appearances by attaching shrink films with various designs to the megaphone body according to the purpose of use, without changing the megaphone body. Because it can do so, it does not simply have a loudspeaker effect like traditional megaphones, but instead has 5 graphic characters displayed on the entire surface of the megaphone.

Colors can visually attract people's attention,
Furthermore, since it is easy to make megaphones that can be used for various purposes with a megaphone body of the same shape, manufacturing costs are reduced.
