DETAILED DESCRIPTION OF THE INVENTION
1 is a front view of a container with a handle according to the present invention, FIG. 2 is a front view showing one of a pair of split molds for blow-molding the container with a handle of FIG. 1, and FIGS. FIGS. 4B and 4C are cross-sectional views showing the blow molding mode in the cross section along the line AA in FIG. 2 in the order of steps, and FIGS. 4A, 4B and 4C are blows in the cross section along the line AA in FIG. It is sectional drawing which shows the other example of a shaping | molding aspect in process order.
[0012]
In FIG. 1, a container 1 with a handle according to the present invention is a container body 2 in which a hollow annular handle 3 is formed integrally with a compression welding wall 4. 5 is a mouth part, 6 is a container bottom face. The hollow annular handle 3 includes an outer annular portion 7, an inner annular portion 8 and an opening 9. Opening 9 is a part to put a hand when having a handle 3, I is the outer annular portion 7 Ah at a portion gripped by hand, the handle 3 of the hollow ring via a compression welding wall 4 to the container body 1 integrally by an inner annular portion 8 and the outer annular portion 7 continuing to, that not make a series of annular surrounding the entire periphery of the opening 9.
[0013]
As shown in FIG. 3, the hollow annular handle 3 is a series of hollow parts in which the pressure fluid introduced into the container body 2 part of the Paris during blow molding is partially introduced into the handle 3 part. In addition, the compression weld wall 4 is formed between the container body 2 portion and the handle 3 portion to form a sealed hollow ring, and is formed integrally with the container body 2 through the compression weld wall 4. There is something that consists of. Hereinafter, one aspect of the blow molding will be described in detail in the order of steps based on FIG. 2 and FIG.
[0014]
In FIG. 3, reference numerals 10 and 11 denote a pair of split molds. In one mold 10 and the other mold 11, cavities 12 and 12 for molding the container body 2 part and a handle 3 part are molded, respectively. Cavities 13 and 13 and cavities 14 and 14 for forming a compression welding wall therebetween.
[0015]
In blow molding of the container 1 with a handle shown in FIG. 1, as shown in FIG. 3A, a parison 15 is disposed between a pair of open divided molds 10 and 11 and pre-blowed to reduce the pressure in the parison 15. Hold. Next, as shown in FIG. 3 (b), while the mold clamping of the pair of split molds 10 and 11 is advanced, a pressure fluid is introduced into the parison 15 and blow-molded, and the container body 2 portion and the handle 3 portion are moved to one side. The mold 10 and the other mold 11 are molded into a shape along the cavities 12, 12, 13, 13, 14, 14. As shown in FIG. 2, one mold 10 and the other mold 11 have a cavity 16 for molding the mouth 5 of the container body 2, and the inner diameter of the mouth 5 is provided in the cavity 16. The driving nozzle 17 that regulates is driven in advance.
[0016]
One mold 10 and the other mold 11 have air escape holes 18 and 18 for releasing the air between the cavities 13 and 13 of the handle 3 part and the parison 15 to the outside. Then, vacuum suction is performed from the air escape holes 18, 18 to bring the handle 3 part of the Paris 15 into close contact with the cavities 13, 13 of the one mold 10 and the other mold 11, thereby improving the molding accuracy of the hollow annular handle 3 part. It is improving. When vacuum suction is performed from the air escape holes 18 and 18 as described above, the Paris 15 does not necessarily have to be pre-blowed.
[0017]
Next, as shown in FIG. 3C, the clamping of the pair of split molds 10 and 11 is completed, and the compression welding wall 4 is formed between the container main body 2 portion and the handle 3 portion. 19 and 20 are burrs, and the opening 9 is formed in the handle 3 by removing the burrs 19 after blow molding.
[0018]
The container with handle 1 shown in FIG. 1 can be blow-molded also in the embodiment shown in FIG. As shown in FIG. 4, in one mold 10 of the pair of split molds 10 and 11, and in the other mold 11, cavities 12 and 12 for forming the container body 2 part and a handle 3 part are formed, respectively. Although having the cavities 13 and 13 is the same as that of the embodiment shown in FIG. 3, a communication portion is provided between the cavities 12 and 12 for molding the container body 2 portion and the cavities 13 and 13 for molding the handle 3 portion. A slide core having a cavity 22, 22 for molding 21 and a cavity 22 for molding the communicating portion 21 of the other mold 11, and molding the compression welding wall 4 between the container body 2 part and the handle 3 part. 23.
[0019]
In the blow molding mode shown in FIG. 4, as shown in FIG. 4A, the parison 15 is arranged between a pair of open divided molds 10 and 11. At this stage, the slide core 23 is in a position that coincides with or retracts from the surface of the cavity 22. Next, as shown in FIG. 4 (b), if the pair of split molds 10 and 11 are clamped and a pressure fluid is introduced into the parison 15 and blow-molded, the container body 2 part and the container body 2 part Then, the pressure fluid is introduced into the handle 3 part through the communication part 21 and is formed into a shape along the cavities 12, 12, 13, 13, 22, 22 of one mold 10 and the other mold 11.
[0020]
Therefore, as shown in FIG. 4 (c), the slide core 23 is advanced and protruded from the cavity 22, so that the space between the container body 2 and the handle 3 is compressed and welded. Molded. Other molding and processing means are the same as those in the embodiment shown in FIG.
