Pack for anaerobic products
A pack comprising: a container, the container having a container body, and the container body being sufficiently oxygen permeable to prevent an anaerobically curable composition held therein from curing due to absence of oxygen; and an anaerobically curable composition held within the container is provided. The container body is constructed from a plastics material which is formed from a blend of a thermoplastic starch component and a polyethylene.
1. A pack comprising:
a. a container, the container having a container body; and
b. an anaerobically curable composition held within the container;
wherein the container body is constructed from plastics material which is formed from a blend of a thermoplastic starch component, wherein the starch in the thermoplastic starch component is present in an amount from 6% to 33% of the weight of the blend used to form the container body and a polyethylene, and which is sufficiently oxygen permeable to prevent the anaerobically curable composition held therein from curing due to absence of oxygen.
2. A pack according to claim 1 wherein the starch in the thermoplastic starch component is sourced from a renewable source.
3. A pack according to claim 1 wherein the starch in the thermoplastic starch component is present in an amount from 13% to 32% of the weight of the blend used to form the container body.
4. A pack according to claim 1 wherein the starch in the thermoplastic starch component is present in an amount from 20% to 30% of the weight of the blend used to form the container body.
5. A pack according to claim 1 wherein the starch in the thermoplastic starch component is present in an amount from 23% to 30% of the weight of the blend used to form the container body.
6. A pack according to claim 1 wherein the starch in the thermoplastic starch component is present in an amount of about 26% of the weight of the blend used to form the container body.
7. A pack according to claim 1 wherein the polyethylene is present in an amount from 66% to 94% of the weight of the blend used to form the container body.
8. A pack according to claim 1 wherein the polyethylene is present in an amount from 67% to 87% of the weight of the blend used to form the container body.
9. A pack according to claim 1 wherein the polyethylene is present in an amount from 70% to 80% of the weight of the blend used to form the container body.
10. A pack according to claim 1 wherein the polyethylene is present in an amount of about 74% of the weight of the blend used to form the container body.
11. A pack according to claim 1 wherein the oxygen permeability of the container body is at least 2.4 cm 3 in 24 hours based on a wall thickness of 4 mm.
12. A pack according to claim 1 wherein the viscosity of the anaerobically curable composition is from about 10 centipoise to about 8,000 centipoise.
13. A pack according to claim 1 wherein the polyethylene is LDPE.
14. A pack according to claim 1 wherein the blend from which the container body is formed comprises a plasticiser.
15. A pack according to claim 1 wherein the container body is squeezable for dispensing the anaerobically curable composition.
16. A pack according to claim 1 wherein the container body is a bottle.
17. A pack according to claim 1 wherein the container further comprises a dispensing nozzle, for dispensing the anaerobically curable composition from the container.
18. A pack according to claim 1 wherein the container further comprises a dispensing closure for dispensing the anaerobically curable composition from the container.
19. A pack according to claim 1 wherein the container body is coloured by a pigment.
