公報により知られている。Conventionally, in synthetic resin injection molding, a mold is closed to form a desired molding space inside, and the resin is injected into this space through a gate to mold the product. Since the pattern film can be set in the molding space by sandwiching the periphery of the pattern film between the parts, it is possible to mold the product by resin injection and at the same time add a pattern to the surface of the molded product. It is known from publications such as Japanese Patent Publication No. 7'532, Japanese Patent Publication No. 62-21546, and Japanese Patent Publication No. 62-30029.

る。(Function) The above-mentioned method for simultaneous patterning by blow molding of the present invention involves opening the blow molding mold, feeding the synthetic resin parison or sheet extruded from the die into the mold, and applying patterns along the surface side of the parison or sheet. When the patterned film is fed at the same time, the parison or sheet and the patterned film are delivered to the molding space of the mold. However, when the mold is closed, the periphery of the parison or sheet and the patterned film are sandwiched by the joint of the mold, so the periphery of the parison or sheet is sealed and the fluid blown into the inside is prevented from leaking. The pattern film is securely set in the mold, so in this state,
When pressurized fluid is blown into the inside of the parison or sheet, the parison or sheet expands along with the pattern sheet due to the pressure of the fluid, adheres closely to the inner wall of the molding space of the mold, and is molded into the shape of the space. A patterned film is attached to the outer surface, and the pattern is applied at the same time as the molding.

An arbitrary pattern a (including simple coloring with only one color) is formed on the surface by printing, copying, painting, or other means, and this pattern film 3 is unwound from the reel 4 and applied to the surface of the parison 2. The near part is made to hang down along this line, and is supplied together with the parison 2 to a blow molding mold which will be described later.

When expressing the pattern a with ink, paint, etc. that has adhesive properties with this material, the pattern By attaching the film 3 together with a to the parison 2 and coating the pattern a with the film 3, it is possible to omit or simplify the surface treatment of the pattern a, and to protect the pattern a. If the film 3 is made of a so-called removable material that does not have adhesive properties to the parison 2, and the pattern a is expressed with ink, paint, etc. that has adhesive properties to the parison 2, only the pattern a can be created as is known. It is capable of so-called transfer that can be attached to parison 2,
In this case, it is necessary to apply a coating such as tanning on the pattern a to protect it.

After supplying, the mold 5 is closed, the joint part of the mold 5 sandwiches the parison 2 and the pattern film 3, the periphery of the parison 2 is sealed, and pressurized fluid, which is the driving force for blow molding, is blown into the inside of the parison 2. In addition, the patterned film 3 is tightly set in the molding space of the mold 5 by sandwiching the peripheral edge between the joints of the mold 5, and )
A pressurized fluid blowing pipe 6 located inside the parison 2 was provided to close the mold 5 while blowing the fluid into the parison 2, thereby isolating the parts of the parison 2 except for the peripheral edge. In this state, pressurized fluid is sent into the parison 2 to expand the parison 2 together with the patterned film 3 until it completely fills the molding space of the mold 5, thereby molding the molded product with the parison 2 in the same shape as the space. Along with letting
This completes the patterning process in which the pattern a of the pattern film 3 is attached to the surface of the molded product.

While extruding a polystyrene parison of size n, a patterned film with an arbitrary pattern printed with adhesive ink was placed on the negative side of the polystyrene film, and both were heated to about 60'C and heated to glow. Feed the box lid into the open gap of the mold, and close the mold while blowing fluid between the sheets from the fluid blowing tube after feeding. Then, the peripheral edge of the parison sandwiched between the joints of the molds was tightly sealed to prevent leakage of the blown fluid, so when about 7 kg of pressurized fluid was blown into the inside, the parison appeared to be attached to the outside. It expands with the film and is pressed against the inner wall of the molding space in the mold to form the lid of the grow box in accordance with the molding space. At the same time, the patterning process is completed by attaching the patterned film to the surface of the product, as shown in Fig. 7. As shown in the cross section, a glow box lid was obtained in which only the upper surface was patterned with a patterned film.
