Fixed-amount discharge squeeze container

摘要

A fixed-amount discharge squeeze container (10) which discharges a specific amount of content liquid from a discharge port by squeeze deformation of a container body (11) includes a squeeze-deformable plastic-made container body (11) and a squeeze operating portion (14) to perform squeeze operation is arranged at a barrel portion (13) of the container body (11). The squeeze operating portion (14) has a cross-sectional shape formed with a compression face portion (16) having a mountain-like section including a pair of inclined face portions (15) arranged along two faces intersecting obtusely and a compression support portion (18) having an arc-shaped section which is jointed integrally with foot parts (19b) of the compression face portion (16) respectively via an edge line portion (17). The compression face portion (16) is restricted so as not to be flipped into a valley-like shape after the inclined face portions (15) deforms until force to expand the distance between the bilateral foot parts (19b) vanishes.

主权项

1. A fixed-amount discharge squeeze container, comprising:
a plastic squeeze-deformable container body to discharge a specific quantity of liquid from a discharge opening with squeeze deformation of the container body; and a squeeze operating portion arranged at least at one part of the container body, wherein the squeeze operating portion has a cross-sectional shape formed with a compression face portion having a mountain-like section comprising a pair of inclined face portions present along two faces intersecting obtusely and a compression support portion having an arc-shaped section or a U-shaped section that is jointed integrally with foot parts of the mountain-like section of the compression face portion respectively via an edge line portion; the pair of inclined face portions expand a distance between the bilateral foot parts of the mountain-like section at the edge line portions against the compression support portion having the arc-shaped section or U-shaped section when the pair of inclined face portions are deformed to expand the intersecting angle therebetween when a predetermined position of the top part of the mountain-like section of the compression face portion is compressed, while the compression face portion is restricted so as not to be flipped into a valley-like shape after the inclined face portions deforms until an expansion force vanishes, so as to prevent occurrence of variation in a squeeze deformation amount of the container body during repeated squeeze operations performed by pressing the predetermined position; and the inclined face portions are discontinuous surfaces and, in an un-deformed state, are flat in at least a lateral direction of the container.
