Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

Claims

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
optionally a closure for closing the container body, the container body comprising, a base, opposing front and rear walls on the base and opposing side walls, each side wall intermediate the front and rear walls and on the base, and the container body being squeezable to allow dispensing of the product through the aperture;
each side wall having a curved profile along its
path between the front and rear walls,

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 said at least one wall, beyond which the
container becomes substantially easier to
compress .

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 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
optionally a closure for closing the container body,
the container body comprising, a base, opposing
front and rear walls on the base and opposing
side walls, each side wall intermediate the front and rear walls and on the base, and the container body being squeezable to allow dispensing of the
product through the aperture;
the container having 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.

4. A container according to Claim 3 wherein each side wall has a curved profile along its path between the front and rear walls 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 b"ecomes substantially easier or substantially more difficult to compress.

5. A container according to Claim 1, Claim 2 or Claim 4 wherein the curved profile of the side walls follows a path which changes direction to turn inwardly and to turn
outwardly again.

6. A container according to Claim 5 wherein the curved profile runs along substantially all of each side wall.

7. A container according to any preceding Claim wherein the front and rear walls are flat or substantially flat.

8. A container according to any one of Claim 1, Claim 2 and Claims 4 to 6 wherein the compressive dispensing range of movement of the walls is compression of up to 5mm.

9. A container according to any preceding Claim wherein the container is constructed of the material selected from the group consisting of polyolefin materials, for example HDPE; MDPE; LDPE including LLDPE, and PP and combinations thereof.

10. A container according to any preceding Claim wherein the container is in the form of a bottle.

11. A container according to any preceding Claim 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.

12. A container according to any preceding Claim 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.

13. A container according to any preceding Claim wherein the container is constructed so that a force of from about 6 to about UN will move said at least one wall toward the other by a distance of about 1 mm.

14. A container according to any preceding Claim 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.

15. A container according to any preceding Claim 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.

16. A container according to any preceding Claim 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.

17. A container according to any preceding Claim 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.

18. A container according to any preceding Claim wherein the curable prdduct is a cyanoacrylate product.

19. A container according to any preceding claim constructed of HDPE.

20 . A pack comprising :
(i) a container according to any preceding Claim; and
(ii) curable product held within the container.

21. A pack according to Claim 20 wherein the container is constructed of HDPE and the curable product held within the container is a cyanoacrylate.

22. A container substantially as described herein with reference to and as illustrated in the accompanying
drawings .

23. A pack substantially as described herein with reference to and as illustrated in the accompanying drawings.
