The other end of 4 is connected via a connector 56 to one end of another supply tube 55 inserted from the nose of a patient or the like.

[0003] Such a dedicated container 51 is mounted on a dedicated jig 58 provided above a stand 57 beside a bed of a patient or the like. The liquid food 50 is hermetically sealed in a can or a paper container, and a nurse or an attendant opens such a container 59 every time of administration, transfers the liquid food 50 to the special container 51, and prepares the patient. And so on.

Disadvantages of using the dedicated container 51 include the necessity of the dedicated container 51, the necessity of transferring the liquid food 50, and the necessity of washing the dedicated container 51 after administration of the liquid food every time. And insufficient hygiene. In order to eliminate such disadvantages,
2. Description of the Related Art In recent years, disposable pouches with a spout that can use a container containing a liquid food as it is as a dedicated container have been adopted.

[0005] Such a disposable type pouch for a liquid food with a spout is formed by, for example, heat-sealing a laminated film into a bag shape such as a four-sided seal type to form a main body of the pouch, and a liquid food is placed under the pouch. An injection port for injecting drinking water for supplying water to a patient or the like after administration of a liquid food is formed on the upper portion, and a plastic injection molded article is formed on the upper portion. Attachment is made by a seal. Further, the heat seal portion on the top of the pouch is formed with a hook hole which can be hooked on a hook or the like above a stand installed beside a bed of a patient or the like.

After the injection of drinking water or the like, the side film drawn out is folded inward as before, and
By closing the opened liquid inlet 8, the pouch 200 with a spout is hung due to the rigidity of the laminated film of the pouch, the flattened form by the heat seals on both sides, and the weight of the contents. Since the liquid inlet 8 is held in the closed state in the lowered state, it is possible to prevent contamination of bacteria and the like, and to administer drinking water and the like to patients and the like in a sanitary and smooth manner as in the case of liquid food. Can be. In addition, since the hole for hanging the pouch 200 with the spout is formed by the hole formed by the cut line, no scum is generated in the punching process, quality control is easy, and productivity is improved. be able to.

Next, the laminated film used in the pouch with a spout of the present invention will be described. As the film used for manufacturing the pouch with a spout for liquid food of the present invention, a laminated film mainly composed of a plastic film is mainly used. For example, conventionally known laminated films used for various food pouches including liquids can be used, and are not particularly limited. The configuration of the laminated film can be appropriately selected depending on the type of the liquid food to be filled, the heating conditions applied during pressurized heat sterilization after filling, and the like.

The laminated film suitably used for the pouch with a spout of the present invention includes a laminated film having the following structure. (1) PET film / adhesive / aluminum foil / adhesive / ON film / adhesive / CPP film (sealant layer) (2) PET film / adhesive / ON film / adhesive /
Aluminum foil / adhesive / CPP film (sealant layer) (3) PET film / adhesive / EVOH film / adhesive / ON film / adhesive / CPP film (sealant layer) (4) PET film / adhesive / uniaxial stretching PP film /
Adhesive / aluminum foil / adhesive / CPP film (sealant layer) (5) PET film / adhesive / (silica or alumina deposited layer) ON film / adhesive / CPP film (sealant layer) However, the present invention is not limited to this, and various combinations of laminated films can be used.

In the above construction, the PET film is a biaxially oriented polyethylene terephthalate film, the ON film is a biaxially oriented nylon film, the PP film is a polypropylene film, the CPP film is a non-oriented polypropylene film, and the EVOH film is an ethylene-vinyl acetate copolymer. The saponified film and the (silica or alumina deposited layer) ON film indicate a biaxially stretched nylon film on which silica or alumina is deposited.

The PET film or ON film acts as a base film, and imparts not only mechanical strength but also heat resistance and printability to the pouch. Further, the aluminum foil, EVOH film and ON film (silica or alumina vapor deposited layer) of the intermediate layer impart gas barrier properties to the pouch. In the pouch with a spout of the present invention, the uniaxially stretched PP film is laminated so that the stretching direction coincides with the direction of an opening instruction line 9 for opening the liquid inlet 8 of the pouch. When opening part 8,
It can be easily torn and opened along the opening instruction line 9.

The innermost CPP film functions as a sealant layer for heat sealing and has excellent heat resistance and low odor. Therefore, after filling and sealing the contents as in the present invention, the pouch is pressurized together. It is preferably used for a liquid food pouch that is heat-sterilized. In addition, as long as it has the same function and effect as the above-mentioned respective film materials, the present invention is not limited to the above-mentioned laminated structure, and can be used by appropriately changing.

Next, a method for manufacturing a pouch with a spout according to the present invention will be described. The pouch with a spout of the present invention can be easily manufactured basically by using a bag making machine corresponding to the pouch type of the main body and adding necessary processing equipment thereto. . However, the pouch 100 with a spout shown in FIG. 1 is a form to which a pouch of a four side seal type is applied, and the pouch 200 with a spout shown in FIG. 2 is a form to which a pouch of a gusset type is applied. However, in both cases, the conventional bag making machine for standing pouches is capable of making two rows of butt bags. It can be manufactured using this.

For example, the pouch 2 with a spout shown in FIG.
In the case of 00, it can be easily manufactured by utilizing the above-described two-row butt-bag making machine for standing pouches and appropriately adding a processing device as described below to this. That is, the body part of the pouch 200 is folded by using the bottom film folding processing parts on both sides of the two-row butt bag making machine to fold the side films of the gusset parts 4 and 4 on both sides, and cut the side films into necessary portions respectively. After the notch 13 is provided, the front and rear wall films 1, 1 '
, And heat-sealed with the side seal portions 2, 2 to form a shape having gusset portions 4, 4 on both sides.

The upper and lower heat seal portions of the pouch 200 can be heat sealed by changing only the shape of the seal head of the existing heat seal device in accordance with the respective seal patterns. Further, a punching device for providing a hole 12 with a cut line for hanging the pouch provided in the upper seal portion 6 above the pouch is additionally provided, and an opening instruction line 9 for opening the liquid inlet 8 is provided. If this is formed by printing,
Since the printing can be performed at the same time as the printing of the pouch body, no additional device is required.
When a half-cut line or the like is provided, a punching device, a laser beam irradiation device, or the like for processing these can be added as needed.

The spout 21 is manufactured by injection-molding polypropylene which can be thermally bonded well to the sealant layer of the laminated film because the adhesive base 25 is inserted between the laminated films on the pouch wall surface and attached by thermal bonding. It is preferable to prepare a dedicated heat sealing device and heat-bond it to the pouch. In this case, the spout 21 may be installed inline with the bag making machine by incorporating the heat sealing device into the bag making machine, or may be prepared separately from the bag making machine and installed offline.
