  Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a rear perspective view showing the overall configuration of a packaging body 1 according to the present invention. The film 2 constituting the package 1 is not particularly limited, but generally has a single-sided sealing property in which a sealant layer having a good sealing property is laminated on the inner surface of a base material layer selected according to the packaging application. A synthetic resin film is used. In the package 1, there is a back pasting portion 3 in which a pair of side edges 2 s 1 and 2 s 2 facing each other in the lateral direction (left-right direction in the figure) of the film 2 are bonded together by heat sealing or the like with the inner surfaces facing each other in the shape of a palm. It is formed in the center of the figure. On the outer edge side of the back pasting portion 3, a vertical seal portion 31 extending along the vertical direction (the vertical direction in the figure) is formed. An outer edge of the vertical seal portion 31 is an outer edge 30 a of the back pasting portion 3. A non-seal portion 32 extending along the vertical direction is formed on the inner edge side of the back pasting portion 3. The base part of the non-seal part 32 (boundary position with the bag main body that stores the contents) is the inner edge 30 b of the back pasting part 3.

  Both ends in the vertical direction of the package 1 are set as horizontal seal portions 4 and 5 sealed in the width direction by heat sealing or the like. For example, when a bag structure in which one of these horizontal seal portions 4 and 5 is sealed in advance is supplied, the other is sealed after the contents (not shown) are accommodated in the bag. Further, in pillow packaging, a plurality of items are arranged at intervals inside a cylindrical packaging material formed by back bonding, and correspond to the lateral seal portions 4 and 5 between the front and rear items. The parts are sealed at the same time, and immediately thereafter, the lateral seal parts 4 and 5 are cut off from each other.

Edge seal portions 33 and 34 are formed on the edge portions of the back pasting portion 3 disposed on the horizontal seal portions 4 and 5. As shown in FIG. 2, the edge seal portions 33 and 34 are outside regions 33o and 34o (34o are not shown) adjacent to both sides of the vertical seal portion 31 in the vertical direction (left and right direction in FIG. 2). And inner regions 33i and 34i (34i not shown) adjacent to both sides of the non-seal portion 32 in the longitudinal direction are integrally formed. And the edge seal parts 33 and 34 are sealing the said non-seal part 32 with respect to the exterior of a bag by continuing in any of the said horizontal seal parts 4 and 5 and the said vertical seal part 31. . In the package 1, the portion other than the back pasting portion 3 is a bag main body made of the film 2, and various items are stored in the storage space between the horizontal seal portions 4 and 5 inside the bag main body. It is assumed that

In the back pasting portion 3, the boundary line 30c between the vertical seal portion 31 and the non-seal portion 32 is formed to extend linearly along the vertical direction. Further, opening start structures 33a and 34a are provided at the edge portions of the edge seal portions 33 and 34, respectively. This opening start structure is a notch or notch having a trapezoidal tip shape in FIG. In the illustrated example, the opening start structures 33a and 34a are provided in both of the edge seal portions 33 and 34, but opening is started in at least one of the edge seal portions 33 and 34 in the longitudinal direction. A structure may be provided. For example, in the case of pillow packaging, when the horizontal seal portions 4 and 5 are formed by heat sealing at the same time, and then the horizontal seal portions 4 and 5 are cut and separated, together with the horizontal seal portions 4 and 5 depending on the cutting shape A notch as an opening start structure may be formed on one of the ends of the back pasting portion 3 to be cut, and a protrusion corresponding to the notch may be formed on the other. Also, the opening start structure provided in the edge seal portion 33 and the opening start structure provided in the edge seal portion 34 may be different from each other, but can basically adopt the same configuration as each other. In the following, only the edge seal portion 33 will be described, and description of the opening start structure of the edge seal portion 34 will be omitted.

  FIG. 2 shows an enlarged partial side view of the vicinity of the end of the back pasting portion 3 provided with the opening start structure 33a. However, as the opening start structure of the present invention, in addition to the opening start structure 33a, 34a formed of the trapezoidal notch described above, the opening start structure 33b formed of a cut (I-shaped notch) shown in FIG. Various opening start structures having various shapes such as an opening start structure 33c including a V-shaped notch shown in FIG. 5B can be used. Furthermore, the unsealing start structure is not limited to the above notches and notches (slits), but includes various cut lines composed of perforations, half-cut lines, fine perforations, rows of scars, and the like as shown in FIG. There may be. That is, it is possible to imagine the position of the opening start end 33p corresponding to the tip in the direction in which these tear lines extend and the direction toward the opening destination (vertical direction), and as a result, the vertical direction Any structure can be used as the opening start structure as long as it has an easy-opening action toward the surface.

  Next, with reference to FIG. 2, the detailed structure of the package 1 of 1st Embodiment which concerns on this invention is demonstrated. In the present embodiment, an unsealing start structure 33a is formed which includes a notch configured in a notch shape from the edge of one edge seal 33. The opening start structure 33a has a V-shaped tip shape, and the apex of the tip is an opening start end 33p that is the tip. The unsealing start end 33p is arranged not in the outer region 33o on the vertical side (the left side in the drawing) of the vertical seal portion 31 but in the inner region 33i on the vertical side (the left side in the drawing) of the non-seal portion 32. ing. The position of the opening start end 33p is determined when the tear line extends in the vertical direction from the opening start end 33p and reaches the boundary between the vertical seal portion 31 and the non-seal portion 32 of the edge seal portions 33 and 34. It is intended that the line enters the non-seal portion 32 from the slightly inner edge near the boundary line 30c, and thereafter the tear line extends in the non-seal portion 32 along the boundary line 30c in the vertical direction.

  In the case of this embodiment, the material and structure of the film 2 are not particularly limited. This is because, since the opening start structure 33a is formed in the edge seal portion 33, opening can be easily started even with a film that does not have hand tearability. However, in order to further facilitate the opening, a film having a cut direction having the property of being easily torn in the longitudinal direction is preferable. For example, a uniaxially stretched film (uniaxially stretched polypropylene (OPP), uniaxially stretched in the longitudinal direction) is preferable. Stretched polyethylene (HDPE)) and the like. As an original fabric of the film 2 used for a bag making apparatus such as a pillow wrapping machine, it is desirable to use a material having a cut property along the longitudinal direction of the original fabric.

The film 2 is not particularly limited as long as it is a resin film as described above, but has a two-layer structure of a base material layer and a sealant layer so that bags can be formed using heat sealing. Is preferred. Further, it is preferred that the thickness of the film 2 is 20 ~ 100 [mu] m, it is desirable that 30 to 80 [mu] m. As for the tearability, it may be one having no directionality as described above, but if it is a film having cutability such as a uniaxially stretched film, it is preferable to have cutability in the longitudinal direction.

  3 and 4 schematically show the appearance formed on the packaging body 1 of the first embodiment having the basic structure shown in FIGS. 1 and 2. In the present embodiment, as the appearance of the back pasting portion 3, the vertical seal portion 31 and the surface portion 3A of one surface portion 3A and the other surface portion 3B constituting both the front and back surfaces of the back pasting portion 3 are provided. An unsealed area display 32d extending in the vertical direction along the boundary line 30c between the non-sealed portions 32 is provided. This unsealed area display 32d has an aspect distinguishable from the visual periphery provided on the surface portion 3A of the back pasting portion 3, and extends along the vertical direction, that is, along the boundary line 30c. Have

  The form of the unsealed area display 32d can be composed of, for example, characters, figures, symbols, patterns, unevenness, translucency, reflectivity, color, or a combination of two or more of these. In addition to printing on the film 2, the unsealed area display 32 d can be provided by various methods (hereinafter simply referred to as “printing”) such as pasting, stamping, transferring, engraving, and laser processing. These points are the same for other displays described later.

  In the illustrated example, in the appearance of the back pasting portion 3, the unsealed area display 32 d is a boundary line on the surface portion of the non-seal portion 32 that extends in the vertical direction in one surface portion 3 A of the back pasting portion 3. This is an area formed by strip-shaped printing or the like extending in the vertical direction along 30c. In this unsealed area display 32d, a position that slightly enters the inner edge 30b side from the boundary line 30c is defined as an outer edge line 32do that extends in the vertical direction, and a position that slightly enters the boundary line 30c side relative to the inner edge 30b. This is a belt-like region having an inner edge line 30di extending in the vertical direction. The unsealed area display 32d may be configured by printing two line segments of the outer edge line 32do and the inner edge line 32di, for example, as in the print patterns shown in FIGS. In addition, a character string such as a “cut zone” may be arranged between the outer edge line 32do and the inner edge line 32di. In addition, the unsealed area display 32d is displayed on the outer edge line 32do and the inner edge line as in the print pattern shown in FIG. 9 regardless of whether the outer edge line 32do and the inner edge line 32di are represented by printing or the like. The area between 32 di may be a pattern, color, reflectance, transmittance, etc. different from the area outside. In this case, when the above character string is displayed, the character string may be displayed not only in a predetermined color but also as a blank character as shown in FIG.

  The above-described unsealed area display 32d can also be configured by giving a predetermined display as described above only in the non-sealed portion 32 as shown in the figure, but the vertical seal portion 31 and the non-sealed portion 32 are mutually connected. It can also be configured by setting different characters, figures, symbols, irregularities, patterns, colors, light reflectance and transmittance. For example, in the printing pattern of the film 2 shown in FIG. 9, the outer surface area outside the surface boundary area extending in the vertical direction along the boundary line 30c is painted with a thin first hue (for example, light blue), and the surface By extending the inner surface area inside the boundary area with a dark second hue (for example, dark orange), an extended-shaped unsealed area display is formed. In this case, the outer surface region is formed by printing or the like so that the description of the unsealing method is superimposed on the band-shaped region having the background of the first hue. Further, in the inner surface region, a white character of “cut zone” is displayed in a band-like region having a background of the second hue.

  In the present embodiment, as described above, one feature is an extended-shaped opening area display extending in the vertical direction along the boundary line 30c. In this case, the opening start structure 33a is shown in a manner different from the surroundings. It is preferable to provide opening structure displays 33d and 34d. The opening structure displays 33d and 34d shown in FIG. 3 and FIG. 4 are provided with a border structure in which strip-shaped contour lines of different colors are alternately arranged in the region adjacent to the opening start structures 33a and 34a. . However, the unsealing structure displays 33d and 34d may be pattern regions obtained by printing or the like in a simple uniform manner having different colors and shades from the surroundings.

  Further, the opening structure display 33d can be seen as constituting an arrow-shaped display extending in the vertical direction by an edging structure matched to the notch shape, and the opening direction when the opening start structures 33a and 34a are used is shown. The opening direction indication is also shown. Generally, the opening direction can be displayed by using an arrow-shaped or triangular pattern indicating the opening direction. The opening region display 32d extends not only to the non-sealed portion 32 but also to the edge seal portions 33 and 34 adjacent to the non-sealed portion 32, and is displayed on the opening structure display or the opening direction display 33d. Printed to reach the position. This makes it easier to notice the opening start structures 33a, 34a and makes it easier to grasp the relationship between the opening start structures 33a, 34a and the non-sealed portion 32 or the boundary line 30c, which is the opening area. The opening direction can be easily known.

  In this embodiment, as shown to Fig.6 (a), the back pasting part 3 is comprised by heat-sealing the inner surfaces of the both-sides edges 2s1 and 2s2 of the film 2. As shown in FIG. In this case, in the bag making process and the pillow packaging process, the back pasting portion 3 as the center seal portion is often a bag on either the left or right side as shown in FIG. 6 (b) or (c). It is formed in a state inclined toward the film surface of the main body. As shown in FIG. 6 (b), the inclination of the back pasting portion 3 may be slightly inclined to one side, and as shown in FIG. 6 (c), the film surfaces 2A and 2B of the bag body It may be in a state of being tilted so strongly that it is in close contact with one side of In any case, the surface portion 3A of the back pasting portion 3 on the opposite side (left side in the drawing) to the inclined side (right side in the drawing) of the back pasting portion 3 is easily visible from the outside. Therefore, it is preferable to provide the opening area display 32d, the opening structure display, or the opening direction display 33d on the surface portion 3A. However, a similar display may be provided on the other surface portion 3B.

In the present embodiment, a pair of gripping position displays 33g, 4g or 34g, 5g, which is another feature point, is formed. However, these gripping position displays can be provided independently even when the opening area display 32d is not provided. As shown in FIG. 3, in the surface portion 3A, the first gripping position indications 33g and 34g are printed on the edge seal portions 33 and 34, which are both ends of the vertical seal portion 31, and the regions adjacent thereto by printing or the like. Is formed. The first gripping position display 33 g, 34g are in the outer side region 33o of the edge seal portions 33 and 34, or are formed in the end portion of the vertical seal portion 31 adjacent to the edge seal portions 33 The In the illustrated example, a first gripping position display 33 g, 34g are formed at positions across the boundary line between the end of the outer side region 33o and vertical seal portion 31. Further, the first grip position indications 33g and 34g are directions from the end edges 33e and 34e of the end seal portions 33 and 34 toward the vertical seal portion 31 (this coincides with the vertical direction, that is, the opening direction). It has an arrow shape toward Therefore, since the first grip position indications 33g and 34g in the illustrated example are provided at positions adjacent to the opening start structures 33a and 34a, they also correspond to the opening direction indication described above.

  On the other hand, second grip position indications 4g and 5g are formed on the film surface 2A of the bag body adjacent to the surface portion 3A where the first grip position indications 33g and 34g are provided. The second grip position indications 4g and 5g are formed on the lateral seal portions 4 and 5 or on the film surface 2A of the bag body adjacent to the lateral seal portions 4 and 5. In the illustrated example, the second grip position indications 4g and 5g are formed so as to straddle between the lateral seal portions 4 and 5 and the film surface 2A of the bag body adjacent thereto. The shapes of the second grip position indications 4g and 5g are elliptical in the illustrated example. Note that the shapes, patterns, colors, and the like of the first holding position displays 33g and 34g and the second holding position displays 4g and 5g are not particularly limited.

  In the present embodiment, the parts where the first grip position indications 33g and 34g and the second grip position indications 4g and 5g are formed are gripped by different hands, and the longitudinal direction from the opening start structures 33a and 34a.
