<p>The present invention relates to a content discharge apparatus for a squeeze type multi-layered blow-molded container which dually blow-molds an inner layer bag within an outer container and forms an air hole by a lower part of the outer container. More specifically, the present invention is assembled and configured by coupling a first check valve (30) and an upper cap (10), which control supply of content discharged through a discharge hole (4), to an upper part of the outer container (2) of the multi-layered blow-molded container; and coupling a second check valve (30′) and a lower cap (20), which control supply of external air into the outer container via the air hole (3), to a lower part of the outer container (2). The present invention discharges and uses the content of the inner layer bag via the first check valve (30) as it gradually compresses the inner layer bag (8) by the external air supplied into the outer container via the second check valve (30′) by a pumping operation for pushing the outer container (2), thereby making it convenient to discharge and use the content of the multi-layered blow-molded container compared with a traditional pumping method while having a simple structure and using the content to minimize the remains of the content, so it enhances use efficiency.</p> |
