BEST MODE FOR CARRYING OUT THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a perspective view showing one embodiment of the liquid food pouch 1 of the present invention, and FIGS. 2 and 3 are perspective views showing another embodiment.
[0017]
An important feature of the liquid edible pouch 1 of the present invention is that it does not provide an opening by a separate spout or the like as a means for supplying water used for diluting the contents of the pouch and for washing the indwelling line after use. An opening portion that can be easily torn by a finger is formed, and after the opening is formed, the opening portion is bent downward so that dust can be prevented from entering from the opening portion.
[0018]
The features of the configuration will be described with reference to the drawings.
The liquid food pouch of the present invention is a liquid food pouch in which the periphery of a body made of a plurality of plastic films is heat-sealed, and the lower heat-seal portion 12 is provided with a content pouring tool 13, and the body is branched from the pouch body. have. A suspending means 11 such as a through hole is formed in the upper heat seal portion 15 of the pouch body, and a prospective opening 14 that can be torn in the lateral direction is formed below the body heat seal portion 16 of the branched body. I have.
[0019]
The body 19 on the side where the branched opening portion 14 is formed is bendable from the body branch portion 17. After the opening is formed by means such as tearing the planned opening portion 14, the body 19 is bent. Is bent downward so that the opening faces downward, so that dust does not enter the pouch 1 from the opening. Also, at least one side seal portion 25 of the pouch body and a side seal portion 26 of the branched body are formed with cuts, for example, at positions facing each other when the body 19 is bent, and these cuts are engaged. The branch body may be locked to the pouch body by providing a locking portion 27 such as joining.
[0020]
The film material constituting the liquid edible pouch has conventionally been generally used as a laminated film having an inner layer as a heat seal layer.In the present invention, these materials can be used without any limitation. In order to form it, as shown in FIG. 5, it is preferable to use a laminated film composed of a heat seal layer (inner layer) a / barrier layer (intermediate layer) b / surface layer (outer layer) c. It is preferable to use a laminated film in which the intermediate layer is made of nylon and the outer layer is made of polyethylene terephthalate. This layer structure of the laminated film is particularly suitable when a means for irradiating a laser and tearing the film is employed as a method of forming the predetermined opening. As the method of forming the opening to be opened, in addition to the above-described laser irradiation, a method of directly forming a non-penetrating groove in the laminated film with a blade, a method of pressing a jig having an abrasive surface formed on the laminated film surface, and the like Can be mentioned.
[0021]
In other words, the opening opening portion 14 only needs to allow the portion of the film body to be torn, and the object can be sufficiently achieved only by making a cut in the outer layer portion of the laminated film. According to these experiments, when a laser is applied to the predetermined opening portion, the laser processing portion can be formed only in the nylon layer b of the intermediate layer and / or the polyethylene terephthalate layer a of the outer layer, and the absorption wavelength thereof can be formed. It has been found that since the polypropylene layer c can be maintained in an intact state, it is possible to prevent a fine foreign substance from entering through a crack before use.
Further, if two tear assisting tapes 24 are attached to the outer layer, an opening can be easily formed by tearing between the two tapes at the time of tearing. The distance between the tapes is preferably as close to 0 as possible.
[0022]
Further, in order to further ensure the sealing after the formation of the opening, it is preferable that a plastic linear fastener 23 is additionally provided below the portion where the opening 14 is to be formed on the inner surface of the pouch. The plastic linear fastener is known per se, and male and female fastener members may be laterally welded to both surfaces 21 and 22 of the body in the pouch by heat sealing.
[0023]
The size of the opening scheduled portion 14 may be a size that can accommodate the water supply port, and the formation of the entire pouch in the lateral direction is more than necessary and should be avoided. The size of the opening scheduled portion 14 can be appropriately adjusted depending on the size and shape of the heat seal portion. FIGS. 2 and 3 show an example in which the upper peripheral edge 16 ′ of the branched body 19 is heat-sealed in a step-like manner, and the scheduled opening portion is formed in the upper part of the heat-sealed portion. An embodiment is shown.
