The present invention also relates to a fluid-administered bag-like container that can be suspended to administer the contents.

  Fluids of tube enteral nutrients and tube enteral liquid foods are stored in packaging containers such as cans, bottles, pouches, paper containers, etc., but they are transferred to dedicated containers in advance, and tubes are placed in the dedicated containers. The contents may be administered by connecting. In this case, there is a problem in terms of hygiene management, but there are difficulties in terms of convenience, such as cleaning and disposal of containers, and cleaning of dedicated containers. On the other hand, in recent years, a container having a spout has been developed, and a highly convenient container has been developed that can be connected to a tube for transluminal tube as it is or via an adapter, eliminating the trouble of transferring to a dedicated container. Yes.

  For example, Patent Document 1 below is a packaging bag in which the periphery of a plurality of film pieces is sealed, an inlet member is attached to one side, and a spout member is attached separately from the inlet member. The inlet member is a top surface portion, and a cap made of an outer peripheral portion provided with a female screw on the inner surface depending on the top surface portion and the periphery of the top surface portion; Disclosed on the inner surface of the cap is a packaging bag characterized in that it has an annular projecting portion that is in close contact with or fitted to the inner peripheral surface side and the outer peripheral surface side of the distal end portion of the injection port portion.

  However, in Patent Document 1, since the inlet member is composed of a cap and an inlet portion, the bag body may be bulky and may need to be disposed of separately.

  Further, in the above-mentioned Patent Document 2, it has a bottom portion and can be standing, but when diluted, or when water is injected after administration of the contents, the width is larger than the vertical width, so that it is in a standing state. However, there has been a problem that a large amount of moisture cannot be injected.

  Furthermore, in Patent Document 3, a plurality of suspension holes are formed in the bag-like container to improve usability. However, since the filling device is on the side in the standing state, the suspension holes are always used. Then, it was necessary to inject moisture and the like in a suspended state.

  As described above, none of the above-described conventional techniques has been sufficiently satisfactory in terms of usability in various usage states.

  Therefore, the object of the present invention is to make it easy to administer tube enteral nutrients, tube enteral liquid foods, etc., and to dilute contents or inject water etc. after contents administration. It is an object of the present invention to provide a convenient fluid-administering bag-like container that can be infused more easily and can be easily poured and injected.

  In order to solve the above problems, the fluid-administered bag-like container of the present invention has a substantially square shape, a pair of side wall sheets in which one corner of the upper side is cut obliquely, and a fold line that is folded in two. And a bottom wall sheet inserted between them along the bottom side of the pair of side wall sheets, and the peripheral part of the side wall sheet and the peripheral part of the bottom wall sheet are heat-welded to form a standing type A chuck seal is attached to a diagonally cut corner of the upper side to form a liquid inlet, and the side of the pair of side wall sheets opposite to the liquid inlet A nozzle is attached to the side by sandwiching its base between a pair of side wall sheets and heat-welded, and the side on the liquid inlet side is first positioned at a position substantially opposite to the nozzle. A suspension hole is formed, and this first suspension A second suspension hole is formed at a position closer to the liquid injection port than the hole, and a third suspension hole is formed on the side where the nozzle is attached. The ratio between the width and the height of the side wall sheet is 1: 1 to 1: 1.8 when viewed with the bottom wall sheet disposition portion facing down in a folded state. To do.

  According to the present invention, the liquid can be injected in a standing state when injecting dilution water for contents or moisture for replenishing water after administration of the contents from a liquid injection port having a chuck seal. It is also possible to inject in a state where the second suspension hole is suspended and supported. In this case, since the second suspension hole is provided in the vicinity of the liquid injection port portion, the liquid injection port can be easily injected upward. Moreover, since the ratio between the width and the height of the side wall sheet is 1: 1 to 1: 1.8, it can be injected into the bag-like container even when injected in a standing state or in a suspended state. The amount of liquid that can be filled can be increased. Furthermore, when the administration tube is connected to the nozzle, the operation can be facilitated by suspending and supporting the tube with the third suspending hole. Furthermore, since the liquid inlet is formed by attaching a chuck seal to the diagonally cut corner on the upper side, the opening of the liquid inlet can be enlarged, is not bulky, and needs to be separated and discarded. Absent.

  Moreover, it is preferable that the side edge to which the nozzle of the pair of side wall sheets is attached is formed so that the inner peripheral edge portion of the welded portion gradually protrudes outward toward the nozzle attachment portion. According to this, since the inner peripheral edge portion is inclined so as to protrude outward toward the nozzle mounting portion, the fluid does not accumulate and the fluid does not remain in the container. A fluid can be dripped.

  Furthermore, it is preferable that the width of the liquid inlet to which the chuck seal is attached is 50 to 120 mm. According to this, when opening the chuck seal and injecting drinking water or the like from the liquid inlet, the width of the liquid inlet is as large as 50 to 120 mm, so there is no risk of spilling the injection liquid when injecting, and the liquid Drinking water or the like can be efficiently injected from the inlet.

  According to the present invention, the operability can be improved in various usage conditions such as when injecting water for diluting the contents and water for replenishing the contents after administration of the contents, or when attaching the administration tube to the nozzle. It is possible to provide a bag-like container for fluid administration that can be improved, is not bulky, and does not require separation and disposal.

  Embodiments of the present invention will be described below with reference to the drawings.
