Abstract
A bottle-type plastic container includes a container body and an opening at one end of the container body for allowing liquid contents to be charged into the container and discharged therefrom. The container body has surface portions, which are recessed inwards and opposed to each other to define a grip region therebetween. The grip region includes a panel portion for absorbing deformation of the container body upon pressure drop therein. The panel portion has a width as measured in circumferential direction of the container body, and is provided with at least one circumferential rib having a length that is smaller that the width of the panel portion.
Claims19
A bottle-type plastic container comprising a container body and an opening at one end of the container body, for allowing liquid contents to be charged into the container and discharged therefrom, said container body having two surface portions which are recessed inwards and opposed to each other, a front surface portion extending between the two recessed surface portions, and a rear surface portion defining a grip region between the two opposed surface portions, wherein the grip region includes a panel portion for absorbing deformation of the container body upon pressure drop therein and the front surface portion is devoid of a panel portion for absorbing deformation, said panel portion of the grip region having a width as measured in circumferential direction of the container body, said panel portion being provided with at least one circumferential rib having a length that is smaller that the width of the panel portion.
A bottle-type plastic container comprising a container body and an opening at one end of the container body, for allowing liquid contents to be charged into the container and discharged therefrom, said container body having surface portions which are recessed inwards and opposed to each other to define opposed depressions, a circumferentially extending reinforcing rib being provided at a predefined axial position within each depression to divide each depression into an upper and a lower portion, and a grip region defined between the opposed depressions, wherein the grip region includes a panel portion for absorbing deformation of the container body upon pressure drop therein, said panel portion having a width as measured in circumferential direction of the container body and being provided with at least one circumferential rib having a length that is smaller that the width of the panel portion, said at least one circumferential rib of said panel portion being provided at substantially the same predefined axial position as that of the circumferentially extending reinforcing ribs so that said at least one circumferential rib reinforces the panel portion during grasping of the container in the grip region during use and when liquid content within the container is subjected to a temperature change.
