Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an embossed packaging bag, and more particularly to an embossed packaging bag incorporating the concept of “universal design”.
[0002]
[Prior art]
Packaging bags mainly composed of a synthetic resin film, especially packaging bags having a spout, are used for many purposes such as a refill-only packaging bag while having a problem that the spout is easily blocked.
By the way, various information such as the type and quantity of contents, usage method, and how to open the bag are added in the form of printing on the surface of these packaging bags. It is used by the method.
[0003]
On the other hand, in the world of container packaging in recent years, the concept of “universal design” is to pursue design and usage that considers all people as much as possible, exceeding the various characteristics and differences of people such as age, gender, body and language. Is being introduced, and it is required that anyone can use it fairly and has a high degree of freedom in using it.
[0004]
[Problems to be solved by the invention]
The present invention has been made in view of the above-mentioned problems relating to a packaging bag mainly composed of a synthetic resin film, particularly a packaging bag mainly composed of a synthetic resin film, and has a concept of “universal design”. It is an object of the present invention to provide an embossed packaging bag that is introduced and has improved pouring properties.
[0005]
[Means for Solving the Problems]
[0007]
The invention of claim 1 of the present invention is a packaging bag formed by sealing the peripheral edges of two synthetic resin films on the front and back sides, and has a depth of 10 μm or more and 1 mm indicating the pouring direction by embossing using male and female dies The embossed pattern of the arrow shape below is placed on the unsealed part so that the embossed pattern overlaps at the same position on the two front and back synthetic resin films at the spout part of the packaging bag when the contents are poured out. It is the packaging bag with an emboss characterized by having given.
[0008]
As described above, according to the first aspect of the present invention, since the embossing pattern is formed by the embossing process using the male mold and the female mold, the embossing process can be performed relatively easily. In addition, since the embossed pattern is a shape that indicates the position and direction of the spout from which the contents are extracted, even for consumers who do not know the characters or symbols, the position and direction of the spout can be determined simply by touching the embossed pattern. I can understand.
[0009]
Further, the invention of claim 2, characterized in the invention of claim 1 Symbol placement, the front Kitsutsumi Sobukuro advance, after preheated at a temperature of 100 ° C from 80 ° C, that it has embossed pattern And an embossed packaging bag.
[0010]
According to the invention thus according to claim 2, the packaging bag after bag-making, in advance, after preheated at a temperature of from 80 ° C 100 ° C, since applying embossed pattern, easily decorated with embossed pattern .
[0014]
The invention of claim 3 is the embossed packaging bag according to claim 1 or 2 , wherein the embossed pattern has a convex shape or a concave shape in accordance with the outline of the arrow-shaped pattern. is there.
[0015]
Thus, according to the invention described in claim 3 , since the embossed pattern has a convex shape or a concave shape according to the outline of the arrow-shaped pattern, it is possible to appeal to the viewer by emphasizing the arrow-shaped pattern. it can.
[0018]
DETAILED DESCRIPTION OF THE INVENTION
The embossed packaging bag of this invention is demonstrated in detail below based on one Embodiment.
The embossed packaging bag of the present invention, for example, as shown in FIG. 1, is made of a packaging bag (10) formed by sealing (13) the peripheral edges of two synthetic resin films (11, 12). It is a packaging bag (1) with emboss which gave embossed pattern (15) to the former synthetic resin film or the packaging bag after bag making.
[0019]
As the packaging bag (10), a generally known packaging bag having a peripheral edge sealed (13) such as a three-side sealed bag, a four-side sealed bag, a pillow packaging bag, and a standing pouch can be used. Among them, standing pouches are excellent in display properties because they are self-supporting, and are also used for packaging bags for refilling.
[0020]
Examples of the synthetic resin film (11, 12) used for the packaging bag (10) include biaxially stretched nylon film (ONy) / linear low density polyethylene (L-LDPE), ONy / aluminum foil (Al) / Generally known composite films such as L-LDPE, polyethylene terephthalate film (PET) / Al / L-LDPE, and PET / Al / ONy / L-LDPE can be mentioned, but heat sealability, content resistance, openability It should be determined in consideration of overall tearability, suitability for embossing to be described later, and the like.
[0021]
The embossed pattern (15) may be applied after the bag is formed as a packaging bag, or may be applied at the stage of the synthetic resin film before bag forming.
If the former method is adopted, an embossed pattern can be applied to two front and back films simultaneously, and if the latter method is adopted, an embossed pattern can be applied to one or both of the front and back films.
[0022]
Examples of the embossed pattern include a method using a vacuum molding method or a pressure forming method using male and female molds, or a method using a stamping process using male and female dies.
Although the former vacuum forming method or pressure forming method can process a relatively deep embossed pattern, wrinkles due to squeezing tend to occur.
In the latter method by embossing, the embossed pattern can be made relatively shallow, but wrinkles due to squeezing are less likely to occur. Further, the processing speed does not decrease.
The embossing depth is preferably about 1 μm to 10 mm, more preferably about 10 μm to 5 mm.
[0023]
Moreover, when embossed pattern (15) is given to the spout part of the packaging bag which has a spout (14), the obstruction | occlusion property of a spout part is improved and the spout becomes difficult to obstruct | pour out and the content is poured out. Sexuality is improved.
[0024]
In the case of a packaging bag having a spout (14), it is convenient to display a spout cutout position instruction mark (a). The spout cutout position instruction mark (a) may be formed by any one of perforations, half-cut lines, ruled lines, printed display, or a combination thereof.
By providing a V-shaped or I-shaped cut (16) at the tip of the spout cutting position indicating mark (a), the opening start position and the opening direction can be more easily understood.
[0025]
2 (a) to 2 (d) show an example of a universal design related to the position of the spout, which is embossed with an arrow design to make it easy for anyone to see the position of the spout. It is a representation.
[0026]
【The invention's effect】
As described above, the embossed packaging bag of the present invention can be made into a packaging bag with enhanced product character emphasis, barrier-free display, and pouring property by embossing the surface of the packaging bag.
