Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid substance-enclosing package in which a liquid substance is made of a soft packaging material and filled with the liquid substance.

Instant foods such as instant noodles such as cup noodles and bag noodles are often accompanied by a liquid pack soup (liquid substance enclosing package) in which liquid is packaged. Consumers, when eating, extrude the contents of the liquid pack soup of these instant foods into a container or the like for use. These liquid pack soups are highly convenient and widely used in the food industry.
Normally, consumers try to push out the liquid by applying pressure from the outside of the package with their hands or fingers, but when the content is highly viscous or large, It took some time. There is a great need for efficient squeezing out of liquid from such liquid-enclosed packages. In addition, if it can be squeezed out efficiently, it can greatly contribute to the reduction of the amount of contents remaining inside the package, and can also lead to shortening the cooking time of processed foods. Patent Document 1, for example, is cited as a prior art related to the form of such a liquid soup pack (liquid substance enclosing package).

SUMMARY OF THE INVENTION In the prior art described above, the vicinity of the opening is in a special sealed state. However, it requires a more complicated sealing process than normal sealing.

Therefore, the present inventors have aimed to develop a liquid-enclosed package from which most of the liquid can be more easily and efficiently squeezed out.

As a result of various tests and intensive research by the present inventors, it was surprisingly found that, while using a conventional liquid substance-enclosing package form, a dotted line or an arrow line or the like was formed on the surface of the liquid substance-enclosing package in a predetermined direction. , and when the consumer pushes out the liquid soup from the package, the content can be pushed out efficiently in a short time by adopting means for pushing out the liquid soup in a state of being folded at the fold line. rice field.

Embodiments of the present invention are described below. The invention is not limited to this embodiment.

<Enclosure package>
The liquid substance enclosing package 1 according to the present invention is made of a sheet-like soft packaging material, and its ends are sealed or folded back as necessary to form a substantially flat bag. Various materials such as polyester, polyethylene, polypropylene, nylon, and aluminum can be used, but in general, polyester, polyethylene, stretched nylon, etc. are included in the structure in order to avoid liquid leakage. Material is preferred. In general, a structure consisting of a plurality of layers is adopted in consideration of barrier properties and heat-sealing properties. For example, specific configurations include various configurations such as ONY/LDPE, KONY/LDPE, PET/Al/LDPE, PET/HDPE/Al/CPP, PET/Al/CPP, and PET/VMPET/PE.

In the present invention, it is preferred to add an aluminum layer (Al) or aluminum vapor deposition (VM) film to the material composition. The aluminum layer or aluminum vapor deposition film can effectively block light and oxygen. By using a layer using aluminum in the liquid package of the present invention, barrier properties can be efficiently improved.
However, while the aluminum package has excellent storage performance as described above, it has the drawback that the contents cannot be confirmed. In particular, in the case of a liquid with a certain degree of viscosity such as liquid soup, it is difficult to visually grasp how the contents remain. The present invention is extremely useful in overcoming the potential drawbacks of aluminum packaging materials.
The enclosing package referred to in the present invention has a substantially flat shape, and its shape is assumed to be rectangular, square, or the like. In addition, regarding the size of the rectangle, it is generally assumed that the size of the liquid substance enclosing package is 12 cm x 12 cm or less.

<Seal form>
The liquid substance-enclosing package 1 of the present invention is made of a sheet-like soft packaging material, and its ends are sealed or, if necessary, folded back to form a substantially flat bag. Various configurations are possible, but ultimately the ends are sealed and hermetically sealed to complete the package. Although the form of the seal is not particularly limited, there is, for example, a three-sided seal body as shown in FIG. 1(a). The three-sided sealing body forms a strip of film into a cylindrical shape and seals in the vertical direction, then seals the lower portion in the horizontal direction to form a bag, fills the content, and seals the horizontal direction. It is known as a general manufacturing method to complete the enclosed state by cutting and manufacturing.
Next, there is a four-sided sealing body as shown in FIG. 1(b). The four-sided seal body is generally manufactured by sealing three sides of two films to form a bag body, filling the contents, and then sealing the last side to enclose the bag. there is In the specification of the present application, the four-side seal is described as a horizontal seal for the seal in the horizontal direction and a vertical seal for the seal in the vertical direction with respect to the paper for convenience.

<Liquid>
Various types can be used as the liquid material in the present invention. For example, not only soy sauce and sauce-type liquids but also highly viscous types such as miso and extracts can be used. In addition, they may be mixed with oil or thickening agents or various mixtures. Furthermore, particles of meat, fish, protein, etc. may be present in the liquid. The present invention can be suitably used even when particles are present in such a liquid that is difficult to squeeze out. Moreover, it can be applied regardless of the viscosity.

<Crease line>
In the present invention, folding lines 5 are provided on the outer surface of the enclosing package. The crease line in the present invention is a line for guiding the action of folding the liquid substance-filled package 1 .
The crease line 5 can take various forms. That is, it may be a straight line or a curved line in consideration of the actual thickness and shape of the package. Various line types such as a dotted line, a one-dot chain line, and a two-dot chain line can be used as the line type of the folding line 5 . Also, it is of course possible to add an arrow.

The crease line 5 may be indicated by only a dotted line so as not to indicate that it is a crease line, or it may be positively indicated that it is a line for folding the package 1 . For example, a comment such as "Please fold the pack along the crease line and squeeze out the contents" may be provided. In addition, annotations such as "folding line" and "FOLDING LINE" may be provided, or may be indicated by symbols or the like. Furthermore, it is of course possible to describe the fact that the package 1 is folded and squeezed in the column for the description of the cooking method, etc., without being described on the liquid package 1 itself.
Next, there may be one crease line 5, or a plurality of crease lines. In addition, when there are multiple fold lines 5, the consumer decides whether the fold line 5 should be folded at one point (Fig. 2(a)) or whether it should be folded at multiple points (Fig. 2(b)). It is preferable to indicate clearly on the package 1 so that it can be understood.

Various orientations of the folding lines 5 can be selected. Regarding this point, it is necessary to consider the relationship with the opening 7, which will be described later.
For example, when the opening 7 is provided at the corner where the vertical seal portion and the horizontal seal portion of the three-sided seal intersect, first, as shown in FIG. . Furthermore, it is not limited to this, and can be provided in parallel with the vertical seal as shown in (b). Moreover, as shown in (c), it may be provided in parallel with the horizontal seal.
Any of these types can efficiently squeeze out the liquid content, as will be described later.

Various methods are possible as a specific method for setting the folding lines 5 . First, the crease lines 5 can be provided directly on the outer surface plastic layer. Next, printing or the like may be applied to the inner surface of the surface plastic layer. Furthermore, for example, if it is a general type of composition of outer: plastic layer (PET or nylon, etc.) / aluminum layer / plastic layer (polyethylene, etc.): inner side, a method of printing crease lines on the plastic layer on the surface In addition, using a colored film on the plastic layer on the surface, only the crease line part is not colored and is transparent, so that when viewed from the outside, the internal aluminum layer can be seen through the crease line. It is also possible to use a mode such as

Regardless of which method is used, the fold line 5 may be visually recognized from the outside. Moreover, the crease line 5 may be given a peculiarity of the crease by, for example, folding several times in advance.
In addition to the printed type, perflation and half-cutting can be made visible to the consumer by applying surface treatments such as laser processing and pressure heat processing to the outer plastic layer, and the fold line can be recognized by the sense of touch. Any possible mode is possible. With such a configuration, when the consumer folds the package 1, the presence of the fold line 5 can be recognized not only visually but also by touch, and this serves as a clue to facilitate the folding of the package 1.例文帳に追加

Various modes can also be adopted for the number of folds of the package 1 . For example, it is possible to provide only one folding line 5 and fold it, or to provide a plurality of folding lines 5 and alternately provide mountain folds and valley folds. In this case, it is also possible to add annotations such as mountain folds and valley folds to each fold line.

<Opening>
In the liquid sealed bag of the present invention, the liquid is squeezed out from the opening 7 after the liquid soup is opened. The opening may be of a partially open type as shown in FIG. 4(a) or a fully open type as shown in FIG. 4(b).
In addition, the opening 7 is often provided in the sealing portion. For example, in the case of the three-way seal shown in FIG. 5, the vertical seal portion may be provided with a notch 9 (a), or the vertical seal portion may be a magic cut 11 (b). In addition, there is a method of facilitating opening by making the end part jagged.

<Manufacturing Method of Enclosure Package>

The liquid substance-enclosing package 1 of the present invention can be manufactured by various methods. The manufacturing method is not particularly limited. As an example, a three-way seal type will be described below. In the three-side sealing, as shown in FIG. 6, a long film continuously transported from a film material 63 by a feeding means such as a feeding roller 65 is folded in two and overlapped, and the overlapped ends are vertically A sealer 57 seals to form a vertical seal portion, and a horizontal sealer 59 horizontally seals the superimposed films to form a horizontal seal portion serving as a bottom portion, and the horizontal seals are formed in the transport direction of the film. Then, the nozzle 58 is inserted into the bag from above, and the liquid is supplied to the bag in an open state in which the boundary on the lower side is sealed and the boundary on the upper side is open to the outside. Filling of the body with fluids can be performed. After a predetermined amount of content is filled, the liquid substance enclosing package is formed by repeating the process of laterally sealing again at regular intervals to form laterally sealed portions, and is formed into a film by a cutting means having a cutter 61 or the like. Packages can be continuously manufactured by cutting the substantially central portion of the transverse seal portion (connecting portion).

It is preferable that the crease line 5 in the present invention is provided in advance on the raw film in parallel or obliquely to the advancing direction of the joint. However, it goes without saying that the crease line 5 may be added after each enclosing package 1 is cut.

<Method of squeezing out the present enclosure package>
The enclosing package 1 of the present invention can be used in various ways. That is, there is a method in which the enclosed package 1 is opened, the contents are extruded without first being folded, and then the contents are mostly taken out and then folded along the crease line 5 to squeeze out. Moreover, after opening, the method of directly folding and squeezing out is also possible. FIG. 7 shows an example of the procedure of folding the enclosing package 1 to squeezing it out. As shown in FIG. 7, the user folds the unsealed package along the folding line 5 ((a) to (c)). Next, the opening 7 of the package 1 folded along the folding line 5 is pressed with a finger from the opposite end to squeeze out the liquid material from the opening 7 (( d)-(f)). By this operation, the liquid content can be effectively squeezed out.

<Test Example 1>
A package containing a liquid (liquid soup pack) as shown in FIG. 8(a) was prepared. The liquid soup pack is folded in two in the longitudinal direction, and while the ends are heat-sealed, the lower end is sealed to form a bag with an upper opening, and about 23 g of liquid (miso soup) is poured. After that, the upper part is heat-sealed. The material of package 1 is ONY/VMPET/ON/LLDPE from the outside.
It is a three-sided seal type.
The package 1 had a size of 91 mm long×80 mm wide. In addition, the heat-sealed portion was 7 mm vertically, and the right end (magic cut portion) was 10 mm.

Regarding the package 1, two types of the case where the crease line 5 was added to the surface (Example) and the case where it was not added to the surface (Comparative Example) were squeezed out, and five panelists in their 20s to 40s squeezed out into a small plate. , the weight of the liquid squeezed into the small plate was measured and compared.
For the embodiment, the crease line 5 is set by printing three lines on the surface as shown in FIG. Added note of mountain fold and valley fold at fold line 5-6 on the right side. After opening in the direction of the arrow in FIG. 8(a), after folding along the folding lines as shown in FIG. 8(b)→FIG. 8(d), squeeze out in the direction of the arrow in FIG. 8(d). It was configured like this.
The comparative example was configured without the above crease lines and annotations. Table 1 shows the results.

5人のパネラーによる試験の結果、いずれのパネラーにおいても搾り出し後の液状物の残存量は、折目線を付した液体スープパックの方が少なかった。折目線を付した場合に液状物の搾り出しが良好に行われていることを示す結果である。

As a result of the test by 5 panelists, the liquid soup packs with crease lines showed less residual amount of liquid matter after squeezing in all of the panelists. These results show that the liquid material is well squeezed out when the crease line is provided.
