## Abstract

A container for food products is defined by a cup-shaped basket, which is made of a first polymeric material, and is provided with a gripping handle connected to the basket in rotary manner by means of two coupling elements, which are made of a second polymeric material, and are welded to the basket itself.

## Claims

### Claim 1

Method for manufacturing containers for food products, each container comprising a cup-shaped basket, which is delimited by a bottom wall and by a lateral wall, and is made of a first polymeric material, and a handle for holding the container; the method comprising the steps of:
coupling each free end of the handle to the basket in a rotatory manner by means of a relative coupling element, wherein each coupling element is made of a second polymeric material and is welded to the basket;
making a hole in correspondence to each free end of the handle; and
welding each coupling element to the basket inside the hole of the relative free end.

### Claim 2 (depends on 1)

A method according to claim 1, wherein the coupling elements are welded to the lateral wall of the basket.

### Claim 3 (depends on 1)

A method according to claim 1, wherein the coupling elements are connected to the basket by means of ultrasonic welding.

### Claim 4 (depends on 1)

A method according to claim 1, wherein the coupling elements are welded to the basket with the free ends of the handle arranged between the basket and the coupling elements themselves.

### Claim 5

Method for manufacturing containers for food products, each container comprising a cup-shaped basket, which is delimited by a bottom wall and by a lateral wall, and is made of a first polymeric material, and a handle for holding the container; the method comprising the steps of:
coupling each free end of the handle to the basket in a rotatory manner by means of a relative coupling element, wherein each coupling element is made of a second polymeric material and is welded to the basket;
arranging the coupling elements on a die; and
moving the basket on the die interposing the handle, so as to bend the handle around the die, on the coupling elements, and inside the basket starting from an initial flat configuration.

### Claim 6 (depends on 5)

A method according to claim 5 and comprising, furthermore, the steps of:
making a hole in correspondence to each free end of the handle; and
welding each coupling element to the basket inside the hole of the relative free end.
