Description

  The present invention relates to a method for manufacturing a bag with an antenna and a bag with an antenna.

  Patent Document 1 discloses that an antenna pattern is formed on the outer surface of a synthetic resin eaves by bonding a metal foil having an antenna pattern shape to the outer surface of the eaves made of synthetic resin.

JP-A-3-84156

  The conventional example shown in Patent Document 1 has the following problems.

  Since the metal foil with the antenna pattern shape is adhered to the outer surface of the eaves wall, the metal foil with the antenna pattern shape is difficult to adhere to the outer surface of the eaves wall having a curved surface. It is difficult to attach the antenna pattern to the outer surface of the eaves.

  Thus, since it is difficult to form an accurate antenna pattern on the outer surface of the eaves, the antenna performance may be deteriorated.

  An object of the present invention is to provide a method for manufacturing a bag with an antenna capable of forming a bag with an antenna having an antenna pattern with an accurate shape, and a bag with an antenna.

In the method for manufacturing a bag with an antenna according to the present invention, a metal foil is wound around the outer surface of a cylindrical bag casing made of a synthetic resin for flowing rainwater , and then the metal foil is wound in the axial direction of the casing. Processing to form an antenna pattern is performed by forming an elongated slot .

  It is preferable that the back surface of the metal foil is attached to the casing, and the metal foil is etched to form the antenna pattern.

  Prior to the etching process, a masking layer is formed on the surface of the metal foil, a portion of the metal foil not covered with the masking layer is removed by etching process to form the antenna pattern, and the masking layer is formed after the etching process. The masking layer is preferably used as a surface protection layer of a metal foil on which an antenna pattern is formed.

  Moreover, the cage | basket with an antenna manufactured with the manufacturing method of any one of the said Claim 1 thru | or 3 is also preferable.

Also, the cylindrical casing having an antenna pattern in which a plurality of slots of different lengths arranged in the vertical direction are connected by a narrow groove, or the metal foil on which the antenna pattern is formed is wound around an outer surface However, it is also preferable that the outer cylinder part is covered.

  In the present invention, when the metal foil is wound around the outer surface of the casing, the metal foil is less likely to wrinkle, and the metal foil can be beautifully wound around the outer surface of the casing. The metal foil is wound around the outer surface of the casing. Since the antenna pattern is formed later, it is possible to form a bag with an antenna having an accurately shaped antenna pattern.

  In order to form this cage 6 with an antenna, it forms as follows.

  In the following embodiments, an example of a cylindrical or rectangular tube-like casing 1 such as a bowl will be described. However, the casing 1 is not limited to a bowl, and includes a bowl, a call, an eaves bowl, and the like. It may be.

  In this embodiment shown in FIG. 1 and FIG. 2, first, as shown in FIG. 1 (a) → (b) and FIG. 2 (a) → (b), a cylindrical synthetic resin casing 1 is formed. The metal foil 2 in a state before the antenna pattern 3 is formed on the outer surface is wound.

  In this case, the metal foil 2 has the entire back surface adhered to the outer surface of the housing 1 by an adhesive, adhesion by ultrasonic welding (welding by high frequency induction heating), adhesion by ultrasonic welding, adhesion by hot air welding, adhesion by heat caulking. Is pasted.

  After that, as shown in FIG. 1C and FIG. 2C, the surface of the metal foil 2 attached to the outer surface of the housing 1 is masked and removed by etching for processing the antenna pattern 3 in a later process. The masking layer 4 is covered except for the portion 7 to be formed.

  That is, a portion where the antenna pattern 3 is not processed in the subsequent process is covered with the masking layer 4, and a portion 7 removed by etching for processing the antenna pattern 3 in the subsequent process is exposed without being masked.

  After the masking is performed, an etching process is performed, and the portion of the metal foil 2 that is not covered with the masking layer 4 is removed by the etching solution, as shown in FIGS. 1D and 2D. 2, the antenna pattern 3 is formed.

  In the embodiment shown in FIGS. 1 and 2, the example in which the masking layer 4 is formed after the metal foil 2 is wound around the outer surface of the casing 1 has been described. The metal foil 2 having the masking layer 4 formed on the surface in advance may be wound around the outer surface of the housing 1.

  That is, in the embodiment shown in FIGS. 4 and 5, the metal foil 2 having the masking layer 4 formed on the surface in advance is formed as a cylinder as shown in FIGS. 4 (a) → (b) and 5 (a) → (b). It is wound around the outer surface of the shaped synthetic resin casing 1.

  That is, by forming the masking layer 4 on the surface of the metal foil 2 in advance, a portion of the surface of the metal foil 2 where the antenna pattern 3 is not processed is covered with the masking layer 4. A portion 7 to be removed by etching for processing is exposed.

  After the metal foil 2 having the masking layer 4 previously formed on the surface is wound around the outer surface of the casing 1 in this way, etching is performed, and the metal foil 2 as shown in FIGS. 4 (c) and 5 (c) is obtained. The portion of the foil 2 that is not covered with the masking layer 4 is removed, and the antenna pattern 3 is formed on the metal foil 2.

  In the manufacturing method of the embodiment of FIGS. 1 and 2 and the embodiment of FIGS. 4 and 5, after the metal foil 2 is wound around the housing 1, the antenna pattern 3 is formed on the metal foil 2. Therefore, it has the following features.

  That is, since the metal foil 2 before the antenna pattern 3 is formed is wound around the outer surface of the housing 1, the metal foil 2 can be easily wound around the outer surface of the housing 1. Therefore, the metal foil 2 can be beautifully wound around the outer surface of the housing 1.

  Since the antenna pattern 3 is formed on the metal foil 2 that is neatly wound around the outer surface of the casing 1, the antenna-equipped cage 6 including the antenna pattern 3 having an accurate shape can be formed.

  The masking layer 4 may be removed after the antenna pattern 3 is formed. However, as shown in FIG. 3, the masking layer 4 is left without being removed, and the surface protective layer of the metal foil 2 on which the antenna pattern 3 is formed. It may be 10.

  The surface protective layer 10 protects the surface of the metal foil 2 provided with the antenna pattern 3 and prevents rust and the like from occurring. When leaving the masking layer 4 as the surface protective layer 10, the masking layer 4 is formed of a non-conductive material so as not to affect the antenna performance of the antenna pattern 3.

  FIG. 1D, FIG. 2D, FIG. 4C, FIG. 5C, and FIG. 6 show an example of a slot antenna pattern as the antenna pattern 3. In this slot antenna pattern, the antenna pattern 3 is formed by forming an elongated slot 28 in a conductive vertically long rectangular metal foil 2.
