It is to provide a packaging container comprising: a synthetic resin container body having a flange part at a periphery of an opening at an upper end thereof; and a container cap having a top board part and a skirt part provided such that it is suspended from a-periphery of the top board part, and wherein the top board part is heat-sealed onto an upper surface of the flange part of the container body; wherein the packaging container has a first cutout part at an upper end of an outer edge of the flange part. By providing a first cutout part, a packaging container possible to achieve sealing with the container cap stably, and to open the sealing easily and surely as well can be provided, by suppressing the effect of a molten resin on a folded corner part of the skirt of the container cap when the container body is heat-sealed with the container cap.

The present invention relates to a video projector type television receiver in which a prism plate is disposed in front of a color cathode ray tube, a projection lens is located in front of the prism plate and transparent liquid is injected into the space between the color cathode ray tube and the prism plate and the space between the prism plate and the projection lens. So, according to the present invention, since a difference between the refractive indexes of the transparent liquid and each component is not so large as that between the refractive indexes of the air and each component, it is possible to reduce a reflection on each boundary surface and also it is possible to prevent a multiple reflection image from being caused and a light amount from being lost greatly. Furthermore, owing to the liquid cooling effect of the transparent liquid, it is possible to suppress the thermal expansion of each portion so that the resultant influence such as the change of optical path and so on can be reduced.
