1. A method of making a container to which entry is via an opening inset from adjacent container walling, the material of the container being susceptible to deformation when heated, wherein in a first stage an embryo container is formed with a rim defining an opening projecting outwardly from what is to become the container walling, and wherein in a second stage that embryo container walling, at an elevated temperature, is urged outwardly while the rim is held, wherein the rim forms a detent for a pressed-in cover, projects outside the embryo container, having an outer and an inner zones on which the container rests during the formation by blow moulding wherein a blow pins is tightly secured in the opening and in wallings of the embryo container practically to the position below the rim to press outwardly and upwardly and to interact after blow moulding of the upper portion of the container wallings with the bottom surface of the inner zone and effective doubling of the inner zone. 2. A method of making a container as claimed in Claim 1 wherein the formation of the embryo container in the first stage is by moulding using an inner mould core which is subsequently extractable through said opening. 3. A method of making a container as claimed in Claim 2 wherein the formation of the embryo container is by injection moulding. 4. A method of making a container as claimed in any of the preceding Claims, wherein the opening of the embryo container widens towards the mouth, locally thinning the container walling, this thinned portion being deformed in the second stage to co-operate with the underside of the flange. 5. A method of making a container as claimed in any of the preceding Claim, wherein the embryo container has a further flange on the lateral flange, projecting back to surround the opening end of the container. 6. A method of making a container as claimed in any of the preceding Claims, wherein deformation of the thinned portion extends to it being forced against the inside of the further flange and to step out below its free edge. 7. A method of making a container as claimed in Claim 6, wherein the material of the container is transparent and a data band is provided on the inside of the further flange of the embryo container to be legible therethrough, the band being made captive by the deformed thinned portion. 8. A method of making a container as claimed in any of the preceding Claims, wherein at the outer edge of the lateral flange there is, on the upper side, a stepped extension forming with said rib an upwardly open channel around the opening. 9. A method of making a container as claimed in Claim 8, wherein the blow pin is used, having a configuration, conjugating with the rib and peripheral portion. 10. A container made by the method of any preceding Claim. |
