Abstract

According to a first aspect of the invention there is provided a method of manufacturing an applicator and container arrangement comprising moulding an insert from a first material, placing the moulded insert into a mould, moulding an outer structure from a second material over the moulded insert, the second material having limited adhesion to the first material, the outer structure defining a handle portion and a shoulder portion, and having a weakened area between the handle portion and the shoulder portion, providing a body portion in a material compatible with the second material so as to ensure adherence to the shoulder portion of the outer structure, and assembling the outer structure, including the insert, and the body portion. The invention extends to a container and applicator arrangement made in accordance with the method.

Claims

1. A method of manufacturing an applicator and container arrangement comprising:

moulding an insert from a first material;

placing the moulded insert into a mould;

moulding an outer structure from a second material over the moulded insert, the second material having limited adhesion to the first material, the outer structure defining a handle portion and a shoulder portion, and having a weakened area between the handle portion and the shoulder portion;

providing a body portion in a material compatible with the second material so as to ensure adherence to the shoulder portion of the outer structure; and

assembling the outer structure, including the insert, and the body portion.

2. A method as claimed in claim 1, wherein the step of assembling the outer structure and the body portion comprises pre-inserting the body portion in the mould and moulding the outer structure over the body portion and insert.

3. A method as claimed in claim 1, wherein the step of assembling the outer structure and the body portion comprises securing the outer structure to the body portion using one of press-fitting, welding, spin-welding and gluing.

4. A method as claimed in claim 1, wherein the steps of providing the body portion and assembling the outer structure and the body portion comprises injection-moulding the body portion integrally with the outer structure.

5. A method as claimed in claim 1, which further comprises pre-fitting an applicator portion to the insert.

6. A method as claimed in claim 1, wherein the step of moulding the insert includes the step of integrally moulding an applicator portion with the insert.

7. A method as claimed in claim 1, wherein the weakened area is defined by a plurality of break-off ribs, with the step of moulding the outer structure comprising moulding the plurality of break-off ribs at the junction between the handle portion and shoulder portion.

8. A container and applicator arrangement for a cosmetic product, including:

an insert made of a first material including an elongate stem having a proximal end and a distal end having an applicator portion;

an outer structure made of a second material having limited adhesion to the first material, the outer structure accommodating the insert so as to define a unitary structure, the outer structure defining a handle portion and a shoulder portion, and having a weakened area between the handle portion and the shoulder portion to enable the handle portion to be separated from the shoulder portion; and

a body portion extending from the shoulder portion of the outer structure for accommodating the cosmetic product.

9. A container and applicator arrangement as claimed in claim 8, wherein the applicator portion is fitted to the elongate stem.

10. A container and applicator arrangement as claimed in claim 8, wherein the weakened area is defined by a plurality of break-off ribs.

11. A container and applicator arrangement as claimed in claim 8, wherein the handle portion can be separated from the shoulder portion with an opening force of between 10 N.cm and 30 N.cm.

12. A container and applicator arrangement as claimed in claim 8, wherein the body portion is made from a multi-layer co-extruded tube sleeve.

13. A container and applicator arrangement as claimed in claim 8, wherein the first material is polyoxymethylene (POM) and the second material is a polyethylene (PET).

14. A container and applicator arrangement as claimed in claim 8, wherein the first material is a polyethylene and the second material is polypropylene (PP) including a slip additive.

15. A container and applicator arrangement as claimed in claim 8, wherein the first material is a copolyester and the second material is a polyethylene.

16. A container and applicator arrangement as claimed in claim 8, wherein the outer pad includes an internal integrally moulded wiper element that snugly accommodates the insert.

17. A container and applicator arrangement as claimed in claim 16, wherein the wiper element comprises a lip for engaging an indent defined on the insert so as to sealingly engage the insert in a snap-fit when the insert is fitted to the outer structure.

18. A container and applicator arrangement as claimed in claim 8, wherein the insert includes a screw thread for engaging a complementary screw thread defined on an internal portion of the shoulder portion.
