It is a cross section. 3A to 3C are a front view, a top view, and a bottom view of the case 4, respectively.

  The container 2 used for the inverted container unit 1 is a so-called delami container made of synthetic resin. That is, the outer shape of the container 2 is formed by the outer layer body 2a, and a flexible bag-like inner layer body 2b is connected to the inside of the mouth portion 2c inside the outer layer body 2a. As a result, the inner layer body 2b can be peeled from the inner side of the outer layer body 2a, leaving the inside of the mouth 2c of the outer layer body 2a.

  The liquid content C filled in the container 2 is introduced inside the inner layer body 2b, and is held in a liquid-tight state by mounting the pump dispenser 3 on the mouth 2c of the container 2. The pump dispenser 3 is extended in a direction intersecting the container axis O (for example, a direction orthogonal to the axis O), and a nozzle 3n for discharging the contents C is opened downward.

  The pump dispenser 3 has a base 3a with a built-in pump mechanism, and the base 3a is formed with a spout 3b opened upward. A socket 3c having an internal passage is disposed at the spout 3b. The socket 3c according to the present embodiment is connected by fitting means such as undercut fitting made of a combination of unevenness or convexity, but the means is not necessarily limited.

  Reference numeral 6 denotes an adapter with an on-off valve that connects the opening 2c and the pump dispenser 3. After the adapter 6 is inserted into the socket 3c, a means such as a bayonet (the convex portion provided on one side is inserted into the groove side provided on the other side, and then pulled out by rotating in that state. By applying a means that is impossiblely fixed, the pump dispenser 3 is detachably connected.

  The adapter 6 includes a cylindrical body 6a that fits and holds the mouth portion 2c in a non-rotatable manner, a cylindrical valve body 6b that is integrally connected to the inside of the cylindrical body 6a, and a space between the cylindrical body 6a and the valve body 6b. And a valve seat 6c that is non-rotatably connected to the socket 3c. That is, the adapter 6 is integrated with the container 2 via the cylinder 6a, and the pump dispenser 3 is integrated via the valve seat 6c. Accordingly, when the adapter 6 rotates the container 3 clockwise or counterclockwise, the valve body 6b also rotates in synchronization therewith, and opens and closes the flow path formed between the valve seat 6c. If it is difficult to rotate the container 3, it is possible to rotate the container 3 together with the container 3 by providing a knob (lever) outside the cylindrical body 6a as another adapter.

  Thereby, when the operation of pushing and returning the nozzle head (pressing head) 3h provided in the pump dispenser 3 is repeated, the content C in the inner layer body 2b is poured out from the nozzle head 3h while the inner layer body 2b is reduced. It is. In this embodiment, although not particularly shown, the outer layer body is formed by a known method such as providing a slit for introducing outside air at the bottom (pinch-off portion) of the outer layer body 2a or providing an outside air introducing hole in the mouth. It is possible to introduce air between 2a and the inner layer body 2b. Thereby, reduction of the inner layer body 2b can be realized efficiently.

The case 4 is held in a swingable manner via a pin P ₁ at the top of the case body 4a having an opening A capable of accommodating the inverted container unit 1 on the front surface, and fitted to the opening A.
