| 摘要 |
The invention relates to a liquid applicator sachet comprising a top sheet sealed onto a base sheet such that the sheets define between them, in a reservoir portion, a reservoir for holding liquid, and, in an applicator portion, a conduit extending from the reservoir to an outlet opening. The sachet further comprises an applicator pad that covers said opening. The applicator portion is folded and sealed onto the reservoir portion such that a sharp fold is present between the reservoir portion and the applicator portion. The fold blocks the conduit such that a liquid held in the reservoir is prevented from flowing into the conduit. Furthermore, the applicator portion comprises a grip tab between two tear lines. By pulling the tab, the applicator portion tears along the tear lines and part of the applicator portion can be unfolded to allow liquid to flow from the reservoir into the pad. |

1. A disposable liquid applicator sachet, comprising:
a base sheet and a top sheet, each of the base sheet and the top sheet having a reservoir sheet portion and an applicator sheet portion, and said top sheet being sealed onto said base sheet such that the reservoir sheet portions of said base sheet and said top sheet define therebetween a reservoir for holding a liquid, and the applicator sheet portions of said base sheet and said top sheet define therebetween a conduit, which conduit extends from the reservoir up to an outlet opening provided in the applicator sheet portion of the top sheet; and an applicator pad, which applicator pad is attached to the applicator sheet portion of the top sheet, such that the applicator pad covers the outlet opening, wherein the sachet is folded with the applicator portion thereof onto the reservoir portion thereof, and wherein a sharp fold is present between the reservoir portion of the sachet and the applicator portion of the sachet, which sharp fold blocks the conduit to such an extent that a liquid held in the reservoir is prevented from flowing into the conduit, wherein the applicator portion of the sachet is sealed onto the reservoir portion of the sachet in sealing zones, which sealing zones are located on opposite sides of the conduit, and which sealing zones extend up to the fold, wherein the applicator portion of the sachet comprises a tear line on each side of the conduit, which tear lines are each located between the conduit and a sealing zone and which tear lines extend from an edge of the applicator portion up to the fold, and wherein the applicator portion of the sachet comprises a grip tab for pulling the applicator portion of the sachet away from the reservoir portion of the sachet, which grip tab is provided between the two tear lines at a distance from the fold, such that by pulling the grip tab away from the reservoir portion of the sachet, the applicator portion tears along the tear lines and a part of the applicator portion of the sachet, the part comprising the conduit and the outlet opening, can be unfolded to allow a liquid held in the reservoir to flow into the conduit and out of the outlet opening into the applicator pad. |
