Abstract

A dispenser ( 1 ) for liquids includes a reservoir ( 100 ) defining a volume (V 100 ) for housing a liquid ( 150 ); a delivery tube ( 200 ) with a first end ( 201 ) attached to the reservoir, and a second end ( 202 ) distal from the reservoir, the delivery tube including a passage ( 203 ) in fluid communication with the volume of the reservoir and extending away from the reservoir; an applicator element ( 300 ) including an applicator tip ( 320 ) and a base ( 310 ) attached to the second end of the delivery tube, the applicator tip having a plurality of fingers ( 322 ) extending away from the base to a distal end of the applicator element distal from the delivery tube; and a removable seal ( 340 ), wherein removal of the removable seal creates an opening in the passage at a location upstream of the applicator tip and a fluid distribution channel between the fingers.

Claims (26)

1. A dispenser for liquids, the dispenser comprising:

a reservoir defining a volume for housing a liquid;

a delivery tube comprising a first end attached to the reservoir, and a second end distal from the reservoir, the delivery tube comprising a passage in fluid communication with the volume of the reservoir and extending away from the reservoir,

wherein the delivery tube is at an angle of about 30° to 60° relative to the reservoir;

an applicator element comprising an applicator tip and a base attached to the second end of the delivery tube, the applicator tip comprising a plurality of fingers extending away from the base to a distal end of the applicator element distal from the delivery tube; and

a removable seal, wherein removal of the removable seal creates an opening in the passage at a location upstream of the applicator tip and a fluid distribution channel between the fingers.

2. The dispenser of claim 1 , wherein the applicator element and the removable seal are integrally formed to the delivery tube.

3. The dispenser of claim 1 , wherein the reservoir, the delivery tube, the applicator, and the removable seal are integrally formed.

4. The dispenser of claim 1 , wherein the reservoir is made of a resilient material.

5. The dispenser of claim 1 , wherein the reservoir comprises polyolefins, polyethylene, polypropylene, ethylene/propylene copolymer, polyester, polyamide, polyacrylate, polystyrene, or a combination thereof.

6. The dispenser of claim 1 , wherein the reservoir is transparent or translucent.

7. The dispenser of claim 1 , wherein the reservoir is opaque.

8. The dispenser of claim 1 , wherein the delivery tube is tapered from a first cross-sectional area proximal to the reservoir to a second cross-sectional area distal to the reservoir.

9. The dispenser of claim 1 , wherein the plurality of fingers is arranged in a plane.

10. The dispenser of claim 1 , wherein the plurality of fingers is arranged circumferentially about the fluid distribution channel.

11. The dispenser of claim 1 , wherein the removable seal comprises a removable tab disposed distally of the applicator.

12. The dispenser of claim 1 , wherein the removable seal comprises a breakable extension extending between the passage of the delivery tube and the removable tab.

13. The dispenser of claim 1 further comprising a liquid within the volume of the reservoir.

14. The dispenser of claim 13 , wherein the liquid comprises a viscosity from about 5 to about 300 Pas at a shear rate of 1.0/s, and wherein the opening has a size suitable for dispensing the liquid.

15. A method for making a dispenser of claim 1 for liquids, the method comprising:

blow molding a reservoir defining a volume for housing a liquid and a delivery tube attached to the reservoir, the delivery tube comprising a proximal end adjacent the reservoir, a distal end extending away from the reservoir, and a passage in fluid communication with the volume of the reservoir, the passage extending from the proximal end to the distal end;

adding liquid to the reservoir; and

deforming the distal end of the passage to create an applicator.

16. The method of claim 15 , further comprising sealing the distal end of the delivery tube.

17. The method of claim 15 , wherein deforming the distal end comprises forming a removable seal, wherein removal of the removable seal creates an opening in the passage at a location upstream of the applicator.

18. The method of claim 15 , further comprising closing the passage with a closure.
