An object of the present invention is to improve shock resistance of nursing bottles formed of a PES resin so as to provide them with such a sufficient falling impact strength that they can be used pleasantly and safely. The injection-blow-molded PES nursing bottle of the present invention has a gate flash (6) at a central portion of a bottom (5), the flash being generated when the resin is previously injected to prepare a parison. The central bottom portion (5) is raised to be of a convex shape to bulge up towards a mouth of the bottle. A height `h` of such a raised bottom portion is from 9% to 20% of an inner diameter `R` that is possessed by a floor-engaging rim of the bottom, the rim being generally circular in a bottom plan view.

The cabinet frame as set forth in claim 5, in which each of the first, second, and third engagement elements includes an engagement surface; and in which the engagement surfaces of each clip together are oriented so as to be disposed at least partially in a pair of generally perpendicular planes. 7. The cabinet frame as set forth in claim 5, in which the fasteners are oriented oblique to the longitudinal extent of the rails; whereby each clip applies to the associated rail in two substantially perpendicular directions forces transmitted to the clips from the fasteners. 8. The cabinet frame as set forth in claim 5, in which each rail includes a cavity extending substantially throughout the longitudinal extent of the rail; and in which the cavity is in communication with the exterior of the rail through an opening in the rail extending substantially throughout the longitudinal extent of the rail. 9. The cabinet frame as set forth in claim 8, in which each rail includes a first flange and a second flange that are oriented substantially parallel with one another; and in which a longitudinal edge of each of the first and second flanges is disposed adjacent the opening in the rail. 10. The cabinet frame as set forth in claim 9, in which the first and second flanges are each formed with an aperture that defines a seat; in which each of the first, second, and third engagement elements includes an engagement surface; and in which the first and second engagement elements are at least partially received in the apertures with the engagement surfaces of the first and second engagement elements being engaged with the seats. 11. The cabinet frame as set forth in claim 10, in which each rail additionally includes a base, a first leg, and a second leg; the first and second legs extending from the base; the first flange extending from the first leg; the second flange extending from the second leg; the base being oriented substantially parallel with and spaced apart from the first and second flanges. 12. The cabinet frame as set forth in claim 11, in which the engagement surface of the third engagement element is engaged with the base generally opposite the opening in the rail. 13. The cabinet frame as set forth in claim 12, in which at least one of the rails additionally includes a third flange oriented substantially perpendicular to the first and second flanges and extending from the second flange along at least a portion of the longitudinal edge thereof that is disposed adjacent the opening in the rail. 14. The cabinet frame as set forth in claim 5, in which at least one of the rails includes a coating; in which a point of juncture exists on the at least one rail at its region of contact with one of the posts; and in which a point of engagement exists on the at least one rail at each region of contact with one of the engagement members of one of the clips; wherein the coating is at least partially ruptured on at least one of the point of juncture and at least one of the points of engagement as a result of engaging the at least one rail with the one of the posts. 15. A cabinet frame comprising: a plurality of rails; and a plurality of connectors; each rail including a first flange and a second flange oriented substantially parallel with one another and being separated from one another by an opening in the rail that extends substantially throughout the longitudinal extent of the rail; each rail including a cavity extending substantially throughout the longitudinal extent of the rail and being in communication with the exterior of the rail through the opening in the rail; each connector including a post and a plurality of clasping members; each clasping member being associated with one of the rails fasteningly extending between the associated rail and the post; and each clasping member including a clip and a fastener; the clip being engaged with the a
