ABSTRACT:

This application claims priority per 35 U.S.C. §119 (a) and §365 to various Japanese Patent Application Nos.: 11/103887, 11/209359, 11/209371, 11/298731, 11/298732.
TECHNICAL FIELD
The present invention relates to a bag for containing a liquid and a container for accommodating the bag. Specifically, the present invention relates to a liquid containing bag made of a soft material and a container made of a hard material for accommodating the bag.
BACKGROUND ART
Japanese Utility Model Registration Publication No. Sho 58-37803 discloses a conventional holder
300
for a fluid filling bag illustrated in FIGS.
58
(
a
) to
58
(
c
). The holder
300
has two curved walls
301
and two flip plates
303
, which connected by hinges
302
in upper and lower openings of the curved walls
301
. One of the flip plates
303
elastically flips between an open position (convex position) and a closed position (concave position). As illustrated in FIG.
58
(
b
), when the flip plate
303
is switched to the open position, an opening is formed in the holder
300
, and a cavity
304
is formed between the two curved walls. A window
305
is formed in an end portion of the curved wall
301
. This window
305
is selectively closed by a sliding plate
306
. A bag
307
filled with a fluid is accommodated in the holder
300
. A protrusion (lip)
308
is formed on the top surface of the bag
307
, and the protrusion
308
extends through the window
305
of the holder.
When the body of the bag
307
is pressed, the fluid flows from the bag. On the other hand, by fastening the lip
308
of the bag between the sliding plate
306
and the window
305
, the opened bag closes. Thus, the holder
300
retains the remaining fluid.
However, since the sliding plate
306
only opens or closes the window
305
, the conventional holder
300
cannot adjust the flow rate of the fluid that flows from the lip
308
.
DISCLOSURE OF THE INVENTION
It is an object of the present invention to provide a container for accommodating a liquid containing bag capable of adjusting the flow rate of liquid from the bag and a liquid containing bag suitable for use with the container.
To achieve the above object, a first aspect of the present invention provides a container for accommodating a bag that contains a liquid. The container has a container body having an opening, which can be opened and closed, and a removable cap member on the container body for closing the opening. The container body includes a supporter for supporting the upper end portion of the bag and an engaging portion for engagement with the cap member. The cap member includes a fastener for clamping the upper end portion of the bag that is exposed through the opening.
A second aspect of the present invention provides a holder for holding a bag that contains a liquid. The holder has a pair of holding members having an opening and capable of opening and closing, and a cap member capable of closing the opening, and removably disposed on the holding members. The holding members include a supporter for supporting the upper end portion of the bag, and an engaging portion for engagement with the cap member. The cap member includes a fastener for clamping the upper end portion of the bag.
A third aspect of the present invention provides a bag for containing a liquid. The bag has an upper thermally welded zone at the upper end portion of the bag, and a lower thermally welded zone at the lower end portion of the bag. The upper thermally welded zone has first and second ends, and the lower thermally welded zone has third and fourth ends. At least one of the first, second, third and fourth ends includes a pouring zone having a width smaller than the corresponding thermally welded zone.
Other aspects and advantages of the present invention will become apparent from the following description together with the drawings illustrating examples of the principles of the present invention.
