Packaged cosmetic stick product
A packaged cosmetic stick product comprising a cosmetic stick composition mounted on an axially immobile retaining member, the retaining member being reversibly connected to a holder enabling the cosmetic stick product to be held in the human hand, wherein the retaining member comprises arcuate bridge structures separated by holes, the bridge structures arcing into the cosmetic stick composition and being embedded therein.
1. A packaged cosmetic stick product comprising a cosmetic stick composition mounted on a retaining member, the retaining member being reversibly connected to a holder enabling the cosmetic stick product to be held in a human hand, wherein the retaining member is axially immobile relative to the holder and any other associated elements and wherein the retaining member comprises parallel arcuate bridge structures separated by holes, the arcuate bridge structures arcing into the cosmetic stick composition and being embedded therein, characterised in that (i) two of the arcuate bridge structures which are adjacent, curve towards one another at their upper ends in a direction orthogonal to their long axis; or (ii) two of the arcuate bridge structures have on each side two or more parallel bridge structures that do not arc into the cosmetic composition; or (iii) the arcuate bridge structures each have both upper and lower surfaces that are smoothly curved across their full width in a direction orthogonal to their long axis; or by having any combination of features (i) to (iii).
2. A cosmetic stick product according to claim 1 , wherein a ratio of a height to a breadth of the cosmetic stick composition is from 1:2 to 3:2.
3. A cosmetic stick product according to claim 1 , wherein a ratio of a breadth to a width of the cosmetic stick is from 1:3 to 1:1.
4. A cosmetic stick product according to claim 3 , wherein the ratio of the breadth to the width of the cosmetic stick is from 1:2 to 1:1.
5. A cosmetic stick product according to claim 1 , wherein the product has an oval or obround cross-section when viewed from above.
6. A cosmetic stick product according to claim 5 , wherein the parallel arcuate bridge structures span a long axis of the product.
7. A cosmetic stick product according to claim 1 , wherein the arcuate bridge structures have one or more strengthening struts running between them in a direction orthogonal to their long (major) axis.
8. A cosmetic stick product according to claim 7 , wherein the strengthening struts and the arcuate bridge structures have upper surfaces that are smoothly curved across their full width in a direction orthogonal to their long axis.
9. A cosmetic stick product according to claim 8 , wherein the strengthening struts and the arcuate bridge structures have lower surfaces that are smoothly curved across their full width in a direction orthogonal to their long axis.
10. A cosmetic stick product according to claim 1 , wherein two arcuate bridge structures are surrounded on either side by a set of two or more parallel bridge structures that do not arc into the cosmetic composition.
11. A cosmetic stick product according to claim 10 , wherein at least one of each set of the parallel bridge structures passes across the full width of the retaining member at a position at which it sits.
12. A cosmetic stick product according to claim 10 , wherein the parallel bridge structures have upper surfaces that are smoothly curved across their full width in a direction orthogonal to their long axis.
13. A cosmetic stick product according to claim 12 , wherein the parallel bridge structures have lower surfaces that are smoothly curved across their full width in a direction orthogonal to their long axis.
14. A cosmetic stick product according to claim 1 , wherein both the arcuate bridge structures and the parallel bridge structures are entirely within the cosmetic stick composition.
15. A cosmetic stick product according to claim 1 , wherein the cosmetic stick composition is a deodorant stick composition.
