BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pouch having a resealing function using food as a content, and more particularly, a pouch in which retort sterilization is performed after being contained in a pouch, for example, an enteral nutrient or a liquid type. In order to facilitate the extraction, dilution, water replenishment, cleaning of the contents dispensing tube, or resealing after dispensing the contents, a plastic zipper is placed on the inner skin of the pouch, and a zipper is described on the inside of the zipper, that is, on the contents side. By making the zipper pouch with the spout which has the cut-off part which turned over the extension part of the phosphorus plastic film and made it into a weakening part, it becomes difficult to produce a defect in a manufacturing process at the cut-out part of the said zipper, and it blocks even after it is commercialized as a pouch with a zipper. It is not broken by heat or pressure at the time of additional retort sterilization or internal pressure by loading at the time of transportation. Relates to a zipper pouch with an outlet.

Patent document 1 is an invention regarding the zipper pouch with an ejection outlet which this applicant developed. As shown in FIG. 6, the linear fastener (zipper) 2 made of plastic is embedded in the upper part of the pouch (A). By opening and closing this linear fastener 2, it is possible to easily supply water and the like. As for the zipper 2 in the pouch of patent document 1, the linear convex part is formed in one surface of the film-form base material 22, and the recessed part which fits with the said convex part is formed in the surface facing it, The convex part and the concave part are configured to be opened and closed freely, and the cut-off part 23 is formed by the weakened part, in which the film-like base material extending inwardly, that is, the contents of the convex part and the concave part, is folded. After the fastening of the zipper is released, the breaker 23 is breakable.

In this way, the enteral nutrient, liquid or retort food stored in the pouch has a fitting portion by a zipper at the front end of the opening scheduled portion 15 of the pouch, and a film which is a zipper base material inside the zipper portion. Since the blocking part 23 is formed in the part which is provided in this stretched and turned upside down, the content does not leak to the opening plan part 15 even beyond the fitting part of a zipper at the time of retort. Therefore, the contents are not scattered or the fingers are dirty when the opening scheduled portion 15 is opened at the time of use.

Although the manufacturing method of the said plastic zipper is various, it is usually melt-extruded in the state in which the convex part and the recessed part (fitting part of a zipper) were formed in the film-form base material which consists of polypropylene, and water-cooled and dry After entering the nip roll and bending the cut-off portion to the center and winding it in the fitted state, it is released as a product. In the process, the bent portion (cut-off portion formed of the weakened portion) of the film is guide rail of the manufacturing machine. It may come in contact with the back, which may cause a defect such that the weakened portion is not visible, or a pinhole may be formed.

(Best Mode for Carrying Out the Invention)

EMBODIMENT OF THE INVENTION Below, the best embodiment of this invention is described with reference to drawings.

1 is a front view of a zipper pouch 1 with an outlet of the present invention, the main body of the pouch 1 is a plurality of plastic sheets (circumferential edge 11 is sealed) a plurality of sheets (front and back 2 sheets 4, 4 ')). A rigid synthetic spout 31 is fused to the lower periphery of the pouch to form a content spout 3. Moreover, the plastic zipper 2 (henceforth simply a zipper) is arrange | positioned at the upper part in a pouch in the state which fused the upper side end part and the both ends of the zipper longitudinal direction to the pouch main body.

That is, the zipper pouch with the outlet of the present invention is sealed in the state where the end portion 22a of the zipper longitudinal direction of the film-shaped base material 22 of the zipper is sandwiched between the front and back sheets of the peripheral edges of the pouches both ends, and the film-shaped base material is further inserted. (22) is sealed on the inner surface of the seat of the pouch body of the front and back opposite the surface on which the uneven portion is formed in the upper portion from the fitting portion 21 along the zipper length direction to form the zipper fusion portion 25. Doing. The upper end of the pouch body is sealed, and the upper portion of the pouch main body is formed as the opening scheduled portion 15 from the zipper fusion splicing portion 25 below the sealing portion 11.

2 is a cross-sectional view of the zipper 2 of the present invention.

The zipper 2 forms a convex portion 21b on one surface of the film-like substrate 22, and a concave portion 21a is formed on the other surface to engage the convex portion 21b, and the concave portion and the convex portion ( It is bent at the front part from 21a, 21b, and this part becomes the interruption | blocking part 23. As shown in FIG. The blocking portion 23 is usually weakened by making the thickness thin so as to be able to break by hand following the opening of the zipper.

The breaking strength of the cut-off portion 23 does not cause breakage or pinholes even when the pouch after filling the contents is heat sterilized such as retort sterilization or boiling, and when the zipper is opened, Next, it is necessary to have a thickness thin enough to break without applying excessive force, and it is 10 to 150 N / 50 mm in terms of breaking strength, and about 10 to 100 μm in terms of the thickness of the blocking part.

As shown in FIG. 2, an important configuration of the present invention is to install one of the films constituting the blocking portion 23 by further extending from the folded portion, whereby the convex portion 21b and the concave portion 21a are formed. The tongue piece 24 is formed in the surface on the opposite side to the surface, and since the cross section of the interruption | blocking part 23 is entangled more than the tongue piece, and it is located inside, since this cross section contacts a guide roll etc. in the manufacturing process of a zipper, Events such as happening are avoided. Therefore, since the cross-section of the blocking portion 23 is sealed in the pouch in a state where no defect occurs, the blocking portion 23 may be broken or a pinhole may be generated even if the pouch is filled with the contents and subjected to heat treatment such as retort sterilization. The same thing cannot be done, and the contents, the surface in which the convex part 21b and the recessed part 21a were formed, are commercialized in a completely separated state.

The extended installation state of the tongue piece 24 (indicated by H in FIG. 2) is not particularly limited as long as it can achieve the object of preventing the tongue section from being ended and protected by the tongue piece. According to the experiment, at least 0.1 mm or more may be sufficient, and it is most preferable when it is 0.4-0.5 mm from a viewpoint of handling point, material cost, etc. In addition, although the shape of the tongue piece 24 covers the front surface of the longitudinal cross section of the zipper of the blocking part 23 in parallel, most preferably, if the cross section of the blocking part 23 does not contact a guide roll etc. in a manufacturing process, Even if the tongue piece 24 has a partially missing part, there is no problem in performance at all. In view of the purpose, the tongue piece 24 may exist in the right end part along the interruption | blocking part 23. FIG.

The portion of the film-shaped substrate 22 inside the zipper 2 extends to the inner side of the pouch, and the pouch contents are connected to each other as the blocking portion 23 so that the pouch contents of the zipper 2 of the film-shaped substrate 22 Since the surface of the pouch opening scheduled side is not directly contacted, the contents of the pouch heated to high temperature by heat or pressure during retort sterilization do not contact the surface opposite to the contents of the zipper 2. Therefore, the pouch contents are not attached to the concave portion and the convex portions 21a and 21b of the zipper 2, and the periphery thereof, so that the opening scheduled portion 15 at the periphery of the pouch is opened, and the zipper 2 portion is outside air. Even if it comes in contact with, it is possible to prevent the contents from adhering to the part.

As a plastic film which comprises a pouch, what can be sealed by heating is required, and what provided with heat resistance is preferable. Moreover, although a film material can also use a single | mono layer film, in order to make it the material which has heat sealing property and barrier property normally, inner layer (heat sealing layer) / intermediate | middle layer (barrier layer) / outer layer (surface layer), or inner layer (heat sealing) Layer) / intermediate layer (substrate layer) / intermediate layer (barrier layer) / outer layer (surface layer). It is preferable to use a composite film. Among them, the inner layer is polypropylene, the middle layer is nylon, and the outer layer is the inner layer side as a barrier layer. It is especially preferable to use the laminated | multilayer film which consists of polyethylene terephthalate which deposited thin films, such as aluminum oxide and inorganic silicon. As the barrier layer, an ethylene-vinyl alcohol copolymer resin (EVOH), aluminum foil, or the like is used in addition to the vapor deposition layer. As the inner layer, polyethylene may be used in addition to polypropylene, and as the outer layer, nylon or the like may be used in addition to polyethylene terephthalate.

The outlet 3 in the zippered pouch 1 with the outlet of the present invention is a spout molded into a hard plastic generally having a retort aptitude such as polypropylene resin as the contents outlet 31. All the well-known spouts described also in patent document 1 can be used. Since the spout is mounted in the state of being fused between the inner layers of the plastic film at the peripheral edge portion 11 of the plastic film constituting the fuselage of the liquid type pouch, the material of the spout is made of the film inner layer constituting the pouch. The shape of the tip portion may be fused, but the shape of the tip portion may be tapered to facilitate insertion into the pipe. In order to prevent the pipe from being pulled out, a design such as forming an uneven shape on the outer periphery of the tip portion may be appropriate. Moreover, when the ejection opening 3 of the zipper pouch with an ejection outlet of the present invention is formed by attaching the contents ejection outlet (spout) 31 of another member having an ejection nozzle to the pouch body, ejection operation such as attachment of a tube, etc. Although this is easy and preferable, the pouch body may be formed in a nozzle shape without mounting the contents ejection outlet of another member, and may be configured as an ejection outlet.

The zippered pouch with the spout is further provided with a hole 26 for hanging the pouch in a sealing portion at the upper part of the pouch separated from the spout 3, which is suspended on a hook in a hospital or the like and administered to the patient. Suitable as. At this time, the zipper portion 2 can be used as a water supply port after the contents are administered, and the zipper with tongue tongue extended to protect the blocking portion of the present invention is excellent in hygiene and sealing property and can be suitably used.

In addition, although heat sealing is preferable for sealing of the peripheral part of a pouch, you may perform ultrasonic sealing. What is important in this invention is to extend the tongue piece for protecting the cross section of a zip block part, and the shape of a pouch is not specifically limited as long as it is a zipper pouch with an outlet.

In the replenishment of water from the zipper, dilution, or taking out of the contents, the opening scheduled portion 15 above the pouch is opened by means of cutting or the like, and the zipper disposed under the fitted state is opened. Since the weakening part of the interruption | blocking part 23 is broken after opening and closing of the zipper continuously, the moisture replenishment and the contents may be taken out after that.

The opening plan part 15 is for making the zipper part 2 open by cutting or opening the part, and when using a cutting tool such as scissors for opening, such as printing a line on the part. What is necessary is just to show by the method, and in order to be able to tear by hand, you may form the line weakened by laser processing etc.

Moreover, the zipper pouch with an ejection outlet of this invention may be a bottomed one as shown in FIG. This bottomed pouch may seal the peripheral edge part so that it may become a bottomed shape through the film which comprises the bottom part 16 between two films which comprise the front and back.

Since the pouch can be self-supporting, for example, if the pouch is a liquid type pouch, the pouch can be placed on the wagon or the like stably during transportation or movement, and at the time of opening of the water, the hose into the pouch, Injection of water and the like from pots and kettles can be performed stably and reliably.

In addition, as illustrated in FIG. 5, the pouch of the present invention may be provided with a handle portion 14 on at least one side of the upper end portion, for example, in order to make it easier for a user to hold the pouch. At this time, since the opening scheduled portion 15 of the pouch is formed in the handle portion 14, even after opening the pouch, the user puts a finger on the handle portion 14a, and the pouch is opened in a state where it is difficult to grip the pouch. The subsequent work can be performed while holding the wealth.
