Japanese Patent JPH0688356

B2

PURPOSE:To enable the level height of content to be seen from outside and to enable the colored resin with sufficient color effect at its residual part to be used by forming a partial wall of a periphery having higher light-penerating power than that of neighboring part into a longitudinal streak-existing in the whole eight of a vessel. CONSTITUTION:The multilayer hollow vessel 1 with the streak for see-through is a plastic hollow vessel whose whole periphery is enclosed with the wall 6 of a multilayer structure in which an inner layer 2, a barrier layer 4 and an outer layer 3 are laminated with the layers of adhesive intervening between each two layers, and the longitudinal streak 7 for see-through existing in its whole height is provided on one side of the vessel. The barrier layer 4 is the material with small permeability to oxygen, and is composed of e.g. ethylene vinyl alcohol copolymer, and then its jointless whole periphery is made with the resin of uniform composition. At the residual part 8 being the greater part of the vessel wall, both inner layer 2 and outer layer 3 are composed of opaque colored resin 11, i.e. the natural resin colored into white with titanium white. On one hand, at the streak 7 for seel-through, the inner layer 2 and the outer layer 3 are composed of natural resin 12 of same material as the colored resin 11, and at the part of the streak 7 for see-through, the level height of the content in the vessel may be seen from the outside.
