Abstract

(57) [Abstract] [Purpose] An object is to provide a pet collar belt having a belt portion in which the decorative portion does not bleed ink and a method for manufacturing the same. [Structure] Polymerization is performed by appropriately printing one surface of at least one of two transparent synthetic resin film sheets and then adhering these two synthetic resin film sheets with the printing surface inside. The step of forming the sheet, the step of forming the front side member for cutting the polymerized sheet into a part of the belt of the collar, and the step of putting the front side member in the mold with the outer surface of the transparent side film sheet in contact with the cavity wall surface are performed. A molding process of the back side member in which the molten synthetic resin material is injected and integrally joined is sequentially performed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synthetic resin collar belt for a pet having a print such as characters and patterns and a method for manufacturing the same.

[0002]

2. Description of the Related Art Heretofore, a pet collar having a belt having the following structure has been known as a pet collar of this type. That is, a decorative transparent belt surface layer made of a transparent synthetic resin sheet on the back surface of which a suitable design, characters, etc. have been decorated in advance, and a decorative portion is integrally formed on the back side of the belt surface layer by injection molding. The belt main body is made of a soft synthetic resin and is joined in a state of being embedded in a molding resin.

The above belt is manufactured by the following method. That is, the decorative transparent belt surface layer made of a transparent synthetic resin sheet on the back surface of which a suitable design, characters, etc. have been previously applied is oriented so that the back surface decoration portion is exposed inside the cavity. , And then insert it into the mold of the injection molding machine, then close the mold and inject the molten synthetic resin compatible with the above-mentioned sheet resin into the cavity to perform insert molding. The main body of the soft synthetic resin belt is integrally joined and molded on the side.

[0004]

However, according to the above method, when the molten synthetic resin, which mainly constitutes the belt, is injected into the mold, the molten synthetic resin directly contacts the decoration provided on the back surface of the surface layer. Therefore, the ink of the decoration may be melted and bleed due to the influence of the heat of the molten synthetic resin, and a defective product with unclear decoration may be formed.

It is an object of the present invention to provide a pet collar having a belt portion that does not cause ink bleeding in the decorative portion, and a method for manufacturing the pet collar.

[0006]

In order to achieve the above object, a pet collar belt with a print pattern according to the present invention is composed of two synthetic resin film sheets in which transparent synthetic resin film sheets are superposed on the front side and the synthetic material. A front side member having an adhesive structure including a printed surface on which a pattern such as a picture or a character is printed on one of the bonding surfaces of the resin film sheet,
And a back side member integrally joined and laminated on the back side of the front side member by injection molding, and the method for producing the pet collar belt is provided with at least one transparent synthetic resin film sheet. A step of forming a polymerized sheet by adhering these two synthetic resin film sheets with the printed surface being the inner side, after performing appropriate printing on any one side, the polymerized sheet being a partial shape of a belt of a collar or The front side member is cut into the whole shape, and the front side member is put into a mold with the outer surface of the transparent film sheet in contact with the cavity wall surface, and then a molten synthetic resin material is injected into the mold to integrally join the same. The back side member is formed in order.

[0007]

According to the present invention, as described above, since one film sheet is interposed between the printing surface and the molten synthetic resin to be injected,
The heat buildup of the molten synthetic resin is buffered by this film sheet and the amount of heat transferred to the printing surface becomes extremely small.Therefore, the printing ink on the printing surface does not melt and bleed, and discoloration does not occur, and the initial clear state is maintained. It can be joined to the back side member while being held.

[0008]

According to the present invention, since the front side member is formed by a double-layered superposed sheet having the print surface on which the print pattern is printed and which is provided on the joint surface side, the back side member for injection molding does not directly contact the print surface. It is possible to eliminate the influence that the heat of the molten synthetic resin has on the printing surface, and it is possible to manufacture the synthetic resin pet collar belt with a clear print pattern with good yield. Play.

Embodiments of the present invention will be described with reference to the drawings.
First, diisocyanate type, polyester diol type,
Two synthetic resin film sheets are prepared, a transparent urethane film sheet 1 of non-yellowing type formed by blending a resin such as a polyether diol type, and a urethane film sheet 2 of the same kind colored, and either one of the films is prepared. In the embodiment shown in FIG. 1, a colored urethane film sheet 2 is provided on one side with a printing surface on which appropriate characters, patterns and the like are printed by the screen printing with ink 3, and the printing surface is placed inside and two sheets are provided. The film sheets 1 and 2 are adhered to each other with a transparent and heat-resistant adhesive to form a polymer sheet 4.

As the synthetic resin film sheet and the injection molding resin, polyester, PVC, nylon and fluorine-based materials may be used in addition to the above, and the adhesive may be a nylon resin or urethane resin-based hot material. A melt type or a urethane resin-based two-liquid reaction type is also suitable, and offset printing or gravure printing can be adopted as the printing method, and the resin may be mixed with insect repellents such as fleas. is there.

Next, the superposed sheet 4 is cut by a die-cutting machine (not shown) to be cut into a shape conforming to the pet collar belt and the printing surface pattern to obtain the front side member 5.

The front side member 5 thus obtained is inserted into the concave mold part 9 of the half mold 7 of the injection mold 7, 8 so that the outer surface side of the transparent urethane film 1 is in contact with the mold.
After the mold halves 7 and 8 are closed, a soft molten synthetic resin compatible with the front member 5 is injection-molded and integrally joined to the front member 5 to mold the back member 10, and after cooling, the mold halves are molded. By taking it out from the above, a pet resin collar belt 11 made of synthetic resin with a print pattern, which allows the printed surface of the ink 3 to be seen through from the front side, is completed.
