Abstract

A wiper member used in a container for packaging and dispensing cosmetic or care products. The wiper member comprises a housing wherein said housing is having at least one sidewall, wherein the at least one sidewall takes up a wiping configuration and a non-wiping configuration when a component is caused to travel through the housing. In the non-wiping configuration, a lower portion of the at least one sidewall is in an unfolded position and in the wiping configuration, the lower portion of the at least one sidewall folds inwardly upon itself into said housing.

Claims

1. A wiper member for a container for packaging and dispensing products said wiper member comprising a housing, said housing having a proximal end and a distal end that define an opening, said housing having at least one sidewall, the at least one sidewall taking up a wiping configuration and a non-wiping configuration when a component is caused to travel through the wiper member;

wherein an outer surface of a lower portion of the at least one sidewall comprises a wiping surface;

wherein the lower portion of the at least one sidewall is capable of folding inwardly upon itself into said housing;

wherein in an initial relaxed position of the wiper member, the opening at the distal end of said housing has a first diameter;

wherein in the initial relaxed position of the wiper member, the lower portion of the at least one sidewall is in unfolded position and the component is not in contact with said housing;

wherein in the wiping configuration, the lower portion of the at least one sidewall folds inwardly upon itself into said housing such that the wiping surface moves inwardly into said housing and forms a wiping orifice inside said housing;

wherein the wiping orifice has a second diameter; and

wherein the second diameter is smaller than the first diameter.

2. The wiper member according to claim 1 wherein the outer surface of the lower portion of the at least one sidewall is having a plurality of protrusions extending outwards from the outer surface of the lower portion of the at least one sidewall.

3. The wiper member according to claim 2 wherein the lower portion of the at least one sidewall folds inwardly upon itself into said housing such that the plurality of protrusions faces inwardly in to said housing and towards the component to be wiped in the wiping configuration and the lower portion of the at least one sidewall unfolds such that the plurality of protrusions faces away from the component in the non-wiping configuration.

4. The wiper member according to claim 2 wherein the wiper member comprises a proximal end and a distal end and wherein the wiper member takes up the wiping configuration when the component is caused to travel from the distal end of the wiper member to the proximal end of the wiper member and the non-wiping configuration as the component travels in a reverse direction.

5. The wiper member according to claim 4 wherein in the wiping configuration, the lower portion of the at least one sidewall folds inwardly in to said housing such that the plurality of protrusions on the lower portion of the at least one sidewall defines an interstice inside said housing for wiping the component.

6. The wiper member according to claim 2 wherein the plurality of protrusions have a shape such as flange, disc-shaped, finger or cilia.

7. The wiper member according to claim 6 wherein the plurality of protrusions occupy a portion of the outer surface of the lower portion of the at least one sidewall of the wiper member.

8. A container for packaging and dispensing a substance comprising

a receptacle,

a gripping member, the gripping member comprising a cap, a stem and an applicator element, the stem comprising a proximal end and a distal end wherein the stem is connected to the applicator element at its distal end and to the cap at its proximal end, the receptacle has an open end and a closed end thereby forming a cavity for storage of product, and

a wiper member as claimed in claim 1, said wiper member being fitted onto the neck of the container, and

wherein the at least one sidewall taking up a wiping configuration and a non-wiping configuration when the gripping member is caused to travel through the wiper member.

9. The wiper member according to claim 1 wherein the second diameter is at least 20% smaller than the first diameter.

10. A wiper member comprising a housing, said housing having a proximal end and a distal end that define an opening, said housing of the wiper member comprises at least one sidewall wherein the at least one sidewall of the wiper member takes up a wiping configuration and a non-wiping configuration when a component is caused to travel through the wiper member;

wherein an outer surface of a lower portion of the at least one sidewall comprises a plurality of protrusions;

wherein the lower portion of the at least one sidewall is capable of folding inwardly upon itself into said housing;

wherein in an initial relaxed position of the wiper member, the opening at the distal end of said housing has a first diameter;

wherein in the initial relaxed position of the wiper member, the lower portion of the at least one sidewall is in unfolded position and the component is not in contact with said housing;

wherein in the wiping configuration, the lower portion of the at least one sidewall folds inwardly upon itself into said housing such that the plurality of protrusions moves inwardly into said housing and forms an interstice inside said housing;

wherein the interstice has a second diameter; and

wherein the second diameter is smaller than the first diameter.

11. The wiper member according to claim 10 wherein the at least one sidewall is having fold-lines and wherein the at least one sidewall folds inwardly in to said housing along the fold lines when the component is caused to travel from the distal end of said housing to the proximal end of said housing such that the wiper member takes up the wiping configuration.

12. The wiper member according to claim 10 wherein the at least one sidewall unfolds as the component comes in contact with the distal end of said housing while travelling from the proximal end of said housing to the distal end of said housing such that the wiper member takes up the non-wiping configuration.

13. The wiper member according to claim 10 wherein the plurality of protrusions are integrally molded with the lower portion of the at least one sidewall.
