## Abstract

A forming mold (311) is configured to include: a pair of split mold bodies (312) in which an intermediate molded product (61) is accommodated; a pair of handle holding split molds (312) provided in the split mold bodies (315) so as to be slidable in a direction orthogonal to the opening and closing direction of the split mold bodies, and sandwiching a handle (30) therebetween; and driving means (313) connected to the handle holding split molds (312) for sliding the handle holding split molds individually.

## Claims

### Claim 1

A forming mold unit for forming a handle-equipped container by blow molding an intermediate molded product, while disposing the intermediate molded product and a handle for a container within a forming mold, wherein the forming mold comprises:
a pair of split mold bodies in which the intermediate molded product is accommodated;
a pair of handle holding split molds provided in the split mold bodies so as to be slidable in a direction orthogonal to an opening and closing direction of the split mold bodies, and sandwiching the handle therebetween; and
a driving device connected to the handle holding split molds for sliding the handle holding split molds individually.

### Claim 2 (depends on 1)

The forming mold unit according to claim 1, further comprising
a synchronization mechanism for synchronizing sliding movements of the pair of handle holding split molds.

### Claim 3 (depends on 2)

The forming mold unit according to claim 2, wherein
the synchronization mechanism is composed of an engaging protrusion provided in one of the handle holding split molds, and an engaging recess provided in another of the handle holding split molds for engagement with the engaging protrusion.

### Claim 4

A manufacturing apparatus for a handle-equipped container, comprising a forming mold unit for forming a handle-equipped container by blow molding an intermediate molded product, while disposing the intermediate molded product and a handle for a container within a forming mold, comprising: (i) a first manufacturing section at which the intermediate molded product is produced, and (ii) a second manufacturing section comprising the forming mold, wherein the forming mold comprises:
a pair of split mold bodies in which the intermediate molded product is accommodated;
a pair of handle holding split molds provided in the split mold bodies so as to be slidable in a direction orthogonal to an opening and closing direction of the split mold bodies, and sandwiching the handle therebetween; and
a driving device connected to the handle holding split molds for sliding the handle holding split molds individually.

### Claim 5 (depends on 4)

The manufacturing apparatus for a handle-equipped container according to claim 4, further comprising
a transporter that performs carry-out of the handle-equipped container from the forming mold, and transport of the intermediate molded product from the first manufacturing section to the forming mold, simultaneously in the direction orthogonal to the opening and closing direction of the split mold bodies.

### Claim 6

A forming mold unit for forming a handle-equipped container by blow molding an intermediate molded product, while disposing the intermediate molded product and a handle for a container within a forming mold, wherein the forming mold comprises:
a pair of split mold bodies in which the intermediate molded product is accommodated;
a pair of handle holding split molds provided in the split mold bodies so as to be slidable in a direction orthogonal to an opening and closing direction of the split mold bodies, and sandwiching the handle therebetween; and
an actuator device connected to the handle holding split molds, wherein the handle holding split molds are slid individually in response to operation of the actuator.

### Claim 7 (depends on 6)

The forming mold unit according to claim 6, further comprising
a mechanical linkage such that sliding movements of the pair of handle holding split molds are synchronized.

### Claim 8 (depends on 7)

The forming mold unit according to claim 7, wherein
the mechanical linkage is composed of an engaging protrusion provided in one of the handle holding split molds, and an engaging recess provided in another of the handle holding split molds for engagement with the engaging protrusion.

### Claim 9

A manufacturing apparatus for a handle-equipped container, comprising a forming mold unit for forming a handle-equipped container by blow molding an intermediate molded product, while disposing the intermediate molded product and a handle for a container within a forming mold, comprising: (i) a first manufacturing section at which the intermediate molded product is produced, and (ii) a second manufacturing section comprising the forming mold, wherein the forming mold comprises:
a pair of split mold bodies in which the intermediate molded product is accommodated;
a pair of handle holding split molds provided in the split mold bodies so as to be slidable in a direction orthogonal to an opening and closing direction of the split mold bodies, and sandwiching the handle therebetween; and
an actuator device connected to the handle holding split molds, wherein the handle holding split molds are slid individually in response to operation of the actuator.

### Claim 10 (depends on 9)

The manufacturing apparatus for a handle-equipped container according to claim 9, further comprising
a transporter that performs carry-out of the handle-equipped container from the forming mold, and transport of the intermediate molded product from the first manufacturing section to the forming mold, simultaneously in the direction orthogonal to the opening and closing direction of the split mold bodies.
