Abstract

A container suitable for dispensing dispensable moisture sensitive curable products such as a CA with a container body which forms an internal reservoir for holding the product a dispensing aperture provided in the container body. Opposing side wall have a curved profile along its path between the front and rear walls which is arranged to regulate a compressibility ratio between the compressive force regulated to move at least one of the front and rear walls toward the other and the distance compressed so that a yield point is not reached, within a compressive dispensing range of movement of said at least one wall, beyond which the container becomes substantially easier to compress. The dispensing force required is predictable and regular while a desired flexibility is achieved.

First claim

The invention claimed is:

1. A container suitable for dispensing dispensable curable products comprising:
a container body which forms an internal reservoir for holding the product;
a dispensing aperture provided in the container body; and
the container body comprising, a base, opposing front and rear walls on the base and resiliently deformable opposing side walls which bias said front and rear walls apart, each side wall intermediate the front and rear walls and on the base, each of the front, rear and side walls having a respective top opposite the base, a neck containing the dispensing aperture, and a tapered shoulder portion connecting the neck with respective tops of the front, rear and side walls, and the container body being squeezable to allow dispensing of the product through the aperture;
each side wall having a sigmoidal or sinuous curved profile along its path between the front and rear walls, the sigmoidal or sinuous curved profile including first and second convex lobe portions adjacent the front and rear walls, respectively, and a concave dished portion intermediate the first and second convex lobe portions,
which curved profile is arranged to provide a substantially linear relationship between the compressive force required to move at least one of the front and rear walls toward the other and the distance compressed, within a compressive dispensing range of movement of said at least one of the front and rear walls, so that a yield point is not reached, and
at least that part of the reservoir which is to hold the product has a substantially consistent wall thickness.

2. A container according to claim 1 wherein the container has a compressibility profile where the ratio of the force required to compress the container by moving at least one of the front and rear walls toward the other to the amount of compression achieved remains relatively constant.

3. A container according to claim 1 , wherein the curved profile of the side walls follows a path which changes direction to turn inwardly and to turn outwardly again.

4. A container according to claim 3 wherein the curved profile runs along substantially all of each side wall.

5. A container according to claim 1 wherein the front and rear walls are flat or substantially flat.

6. A container according to claim 1 , wherein the compressive dispensing range of movement of the walls is compression of up to 5 mm.

7. A container according to claim 1 wherein the container is constructed of polyolefin materials.

8. A container according to claim 1 wherein the container is in the form of a bottle.

9. A container according to claim 1 wherein at least that part of the reservoir which is to hold the product, has a wall thickness in the range from 0.4 to 1.5 mm.

10. A container according to claim 1 wherein at least the front and rear walls have a flexibility which allows initial compression by a force in the range from 5 to 25 N.

11. A container according to claim 1 wherein the container is constructed so that a force of from about 6 to about 11 N will move said at least one wall toward the other by a distance of about 1 mm.

12. A container according to claim 1 wherein the container is constructed so that a force of from about 11 to about 18N will move said at least one wall toward the other by a distance of about 2 mm.

13. A container according to claim 1 wherein the container is constructed so that a force of from about 18 to about 25N will move said at least one wall toward the other by a distance of about 3 mm.

14. A container according to claim 1 wherein the container is constructed so that a force of from about 25 to about 36N will move said at least one wall toward the other by a distance of about 4 mm.

15. A container according to claim 1 wherein the container is constructed so that a force of from about 36 to about 48N will move said at least one wall toward the other by a distance of about 5 mm.

16. A container according to claim 1 wherein the curable product is a cyanoacrylate product.

17. A container according to claim 1 constructed of HDPE.

18. A pack comprising:
(i) a container according to claim 1 ; and
(ii) curable product held within the container.

19. A pack according to claim 18 wherein the container is constructed of HDPE and the curable product held within the container is a cyanoacrylate.

20. A container suitable for dispensing dispensable curable products comprising:
a container body which forms an internal reservoir for holding the product;
a dispensing aperture provided in the container body; and
the container body comprising, a base, opposing front and rear walls on the base and resiliently deformable opposing side walls which bias the front and rear walls apart, each side wall intermediate the front and rear walls and on the base, each of the front, rear and side walls having a respective top opposite the base, a neck containing the dispensing aperture, and a tapered shoulder portion connecting the neck with respective tops of the front, rear and side walls, and the container body being squeezable to allow dispensing of the product through the aperture;
the container having a compressibility profile of curvature or thickness, evidenced in that the ratio of the force required to compress the container by moving at least one of the front and rear walls toward the other to the amount of compression achieved remains relatively constant, and
at least that part of the reservoir which is to hold the product has a substantially consistent wall thickness.

21. A container according to claim 20 wherein each side wall has a curved profile along its path between the front and rear walls, the curved profile including first and second convex lobe portions adjacent the front and rear walls, respectively, and a concave dished portion intermediate the first and second convex lobe portions, and which curved profile is arranged to regulate a compressibility ratio between the compressive force required to move at least one of the front and rear walls toward the other and the distance compressed so that a yield point is not reached, within a compressive dispensing range of movement of the said at least one wall, beyond which the container becomes substantially easier or substantially more difficult to compress.
