A blow molded plastic container including a neck finish, a shoulder portion, a sidewall, and a base integrally formed with one another. Two indentations in the sidewall create a handgrip and a web extends generally across the interior of the container between the two indentations. A plurality of generally downwardly extending support feet include short feet and long feet. Separating the support feet are a plurality of first and second strap formations. Support surface contact points of the long feet are in a planar relationship with respect to one another, thereby providing the container with stability when empty. After filling, capping and pressurizing, the support surface contact points of the short feet and the support surface contact points of the long feet are all in a planar relationship with respect to one another, thereby providing the container with stability when filled.

The bottle plug as defined in claim 6, wherein the top of the plug provides a slot for manually or automatically screwing it. 8. The bottle plug as defined in claim 2, wherein a protrusion is formed on the inner circumference of the flexible walls to provide the expansion portion engaged with a recession of the leg of the plug while the plug is inserted into the body. 9. The bottle plug as defined in claim 2, wherein an annular groove provides on a bottom of an outer circumference of a wall; a tear strip connects between the bottom of the wall and the annular partition so that the wall can tear off from the body along its groove. 10. The bottle plug as defined in claim 2, wherein the body provides an annular flange at an edge of a hole of the partition for holding the inserted leg of the plug slightly tight. 11. The bottle plug as defined in claim 2, wherein a bottom of the elastomer member provides a hole and a filter arranged therein, the filter is made of cork material and permits only a miniscule amount of air to enter the bottle. 12. A bottle plug comprising: a body providing an annular partition having an upper surface and a lower surface, a wall axially extending from the upper for defining a compartment and a plurality of flexible walls axially extending from the lower surface for defining an expansion portion, an inner circumference of each the flexible wall provides an engagement means; a plug providing a top and a leg, the top is received in the compartment and the leg is engaged with the expansion portion for expanding and provides an engagement means for engaging with the engagement means of the body; and an elastomer member adapted to receive the combination of the body and the plug; wherein an outer circumference of the elastomer member corresponding to the expansion portion of the body is adapted to sealably confront the inner circumference of the bottle neck by the leg engaging with the expansion portion when the bottle plug is inserted into the bottle neck. 13. The bottle plug as defined in claim 12, wherein the leg further provides a slightly tapered end engaged with the expansion portion. 14. The bottle plug as defined in claim 12, wherein a protrusion is formed on the inner circumference of each the flexible wall to provide the expansion portion. 15. The bottle plug as defined in claim 12, wherein the plug provides an annular wall extended from the radially outer annular surface in a direction from the top to the leg; an annular tear strip is attached to the rim of the wall and thus an inner lip forms a retainer for retaining the annular plate of the body while the plug is inserted into the body. 16. The bottle plug as defined in claim 12, wherein an annular groove provides on a bottom of an outer circumference of a wall; a tear strip connects between the bottom of the wall and the annular partition so that the wall can tear off from the body along its groove. 17. The bottle plug as defined in claim 12, wherein the body provides an annular flange at an edge of a hole of the partition for holding the inserted leg of the plug slightly tight. 18. A bottle plug comprising: a body providing an annular partition having an upper surface and a lower surface, a wall axially extending from the upper for defining a compartment and a plurality of flexible walls axially extending from the lower surface for defining an expansion portion, an inner circumference of the wall provides a groove; a plug providing a top and a leg, the top is received in the compartment and the leg is engaged with the expansion portion for expanding, a radially outer annular surface provides a rib for engaging with the groove of the body; and an elastomer member adapted to receive the combination of the body and the plug; wherein an outer circumference of the elastomer member corresponding to the expansio
