Description

  The present invention relates to a pillow package, and more specifically, to an improvement in an opening function.

  As is well known, a pillow wrapping machine forms a tubular film by forming a belt-like film into a tubular shape through a bag making machine, and sealing the overlapped film polymerization ends with a center seal device. On the other hand, on the upstream side of the bag making machine, a product transporting and supplying device for supplying a product to be packaged into the bag making machine at predetermined intervals is arranged. The product is conveyed in a state of being arranged at equal intervals in the cylindrical film. Then, a pillow packaging body that encloses the product is manufactured by sealing and cutting the tubular film so as to cross the horizontal direction at predetermined intervals by an end seal device arranged on the carry-out side of the pillow packaging machine. The

  FIG. 1 shows an example of such a pillow package. The pillow package 1 wraps the product 2 with a cylindrical packaging film 3 and seals the packaging film 3 at an appropriate position. Specifically, the seal portion includes a center seal portion 4 which is sealed by overlapping both side edges of the film along the cylindrical axial direction, and an end seal portion 5 which is formed by sealing the front and rear in the traveling direction in the lateral direction. There is.

  Various packages need to be opened and the product 2 taken out. For this reason, various methods for facilitating opening workability have been attempted. As an example, as in the invention disclosed in Patent Document 1 shown in FIG. 1, the heat-sealed end seal portion 5 can be easily peeled after being bonded, and can be peeled off outside the end seal portion 5. While providing the adhesion part 6, it cuts both corners of the non-adhesion part, and makes it a free state. And by pinching the film part located in the non-adhesion part 6 and pulling away from each other, the end seal part 5 is peeled off to open the package (FIGS. 1B and 1C). )reference). Further, by pulling the above-described picked film portion in a predetermined direction with the end seal portion 5 peeled off as described above, a fold line of four sides parallel to the center seal portion 4 of the main body portion formed in a substantially rectangular shape. 7 is cut off, and the packaging film 3 in which the product 2 is wrapped in a cylindrical shape as shown in FIG. 1 (d) is divided into strips 8 and 9 and opened.

Japanese Patent No. 3738093

  In the pillow package 1 shown in FIG. 1, as shown in FIG. 1 (d), the product 2 is finally divided and opened to expose the product 2. The part 5 needs to be easily peelable, and part or all of the sealed end seal part 5 may be carelessly peeled off and opened. Further, in the state where the four strip-shaped pieces 8 and 9 are opened, the end seal portion 5 remains in the vicinity of the tips of the pieces 8 and 9, and the non-adhesive portion 6 exists at the tip. So it looks bad.

  Furthermore, since the position where the film is torn is fixed by the fold line 7, it can only be divided into four pieces, and it cannot be cut at any position or divided into five or more strips.・ It is not interesting. Moreover, as shown in the figure, when the product is flat, it becomes two wide pieces 8 and two narrow pieces 9, and the open state is unbalanced, corresponding to the individuality and sensitivity of each user. There is a problem that it cannot be opened in a graceful cut / open state.

  In order to solve the above-described problems, the pillow package of the present invention is (1) a pillow package in which a product is stored in a main body made of a cylindrical packaging film and a predetermined portion of the packaging film is heat-sealed. The body has a lateral direction in which the packaging film can be cut in a lateral direction along the end seal portion at a predetermined position from the heat-sealed end seal portion at one end in the axial direction of the body. While providing the easy opening part, the vertical direction easy opening part which can cut | disconnect a packaging film in the vertical direction from the opening part of the main body cut | disconnected and opened by the horizontal direction easy opening part was provided.

  In this way, first, a predetermined position from the end seal portion of the main body is cut in the horizontal direction using the easy opening portion in the horizontal direction, and the main body is opened by excising the tip portion (head portion 11a) of the main body together with the end seal portion. To do. Next, the packaging film can be cut open while being divided into a plurality of strips by tearing the packaging film of the main body in the longitudinal direction using the longitudinal easy-opening portion facing the opened edge. At this time, since the end seal part has already been detached from the main body by the opening process using the laterally easy-open part, the free end of the divided strip has no end seal part and looks good.

  The laterally easy-opening portion and the longitudinal-direction opening portion may be constituted by a scar group formed so as to extend laterally at a predetermined position from the end seal portion. The scar group is called a magic cut and can be easily cut from anywhere. For example, the scar group can be cut from any point in the extending direction of the scar group in a direction perpendicular to the extending direction. It can be done. Therefore, the scar group formed so as to extend in the lateral direction can be used to cut in the vertical direction perpendicular to the extending direction of the scar group. Of course, the direction (lateral direction) in which the scar group extends is like a perforation, so that it can also be cut in the horizontal direction. Therefore, it can comprise by using both the horizontal direction easy opening part and the vertical direction easy opening part by the scar group which concerns. Also, since it can be cut longitudinally from any position of the opened edge, it can be divided into strips of a predetermined width according to the user's preference, and one surface of the main body is divided into a plurality of strips It can be opened according to the user's preference, and there is an impact.

  (3) The main body may be designed so that a part or all of the region where the scar group is formed is informed of the position of the region. This is preferable because it can be easily understood from which one the lateral / longitudinal direction can be opened.

  (4) A perforated shape extending in the lateral direction is formed at a predetermined position from the end seal portion of the main body, and the perforated shape is cut into the main body at a cut mark remaining on the main body when cut in the lateral direction. It is preferable to form an entrained longitudinal tear start. The perforations correspond to the patterns P1 to P4 shown in FIG. 4 of the embodiment. Further, the tearing start portion in the vertical direction corresponds to the circular patterns P1 ′ and P3 and the vertical line portions P2 ″ and P4 ″.

  (5) The said packaging film is good to provide the tearability of the vertical direction. Such a film can be constituted using a uniaxially stretchable film or a biaxially stretchable film. If it does in this way, since a packaging film is cut | disconnected straightly in the vertical direction, since a strip can be easily made into a beautiful shape, since the figure of an open state also becomes beautiful, it is preferable.

  It can be a pillow package that is clean and has an impact.

It is a figure which shows the conventional pillow package. 1 is an overall view showing a preferred embodiment of the present invention. It is a top view of the principal part which shows suitable one Embodiment of this invention. It is a top view of the principal part which shows suitable one Embodiment of this invention.

  FIG. 2 shows a preferred embodiment of the pillow package 10 according to the present invention. As shown in the figure, this pillow wrapping body 10 has end seal portions 12 and 12 'formed at both ends in the longitudinal direction of a main body 11 made of a packaging film formed into a cylindrical shape. The center seal portion is also formed along the longitudinal direction, and the product 13 is sealed.

  At a predetermined position from one end seal portion 12 of the cylindrical portion of the main body 11, a lateral easy-open portion 14 capable of cutting the packaging film in the lateral direction (the waistline direction) along the end seal portion 12 is formed. . Furthermore, the longitudinal direction which can be torn along the longitudinal direction (longitudinal direction) on the lateral direction easy-opening portion 14 or including the laterally easy-opening portion 14 and inwardly parallel to the center seal portion with respect to the end seal portion 14. An easy-open portion 14 is provided. Furthermore, the packaging film which comprises the main body 11 is a laminated | multilayer film provided with the uniaxial or biaxially stretched film in the predetermined layer, Comprising: It has the property which is easy to cut | disconnect at least to the vertical direction.

  By providing the laterally easy opening part 14, the user first cuts the packaging film at the laterally easy opening part 14. Thereby, as shown in FIG.2 (b), the head part 11a by the side of the end seal part 12 is separated from the main body 11 rather than the part by which the horizontal direction easy-opening part 14 was torn, and the end of the product 13 is exposed.

  Moreover, since the pillow easy-to-open part 15 is provided so that the pillow package 10 of this embodiment may include the horizontal easy-open part 14 on the horizontal direction easy-open part 14, the opened pillow package 10 One end of the longitudinal easy-opening portion 15 is located at the opening portion, that is, the end portion that is cut open by the lateral easy-opening portion 14 of the main body 11. Therefore, the user cuts the remaining main body 11 using the exposed vertical easy-opening portion 15 at a plurality of locations in the vertical direction along the center seal portion. Thereby, as shown in FIG.2 (c), the main body 11 is divided | segmented into several elongate strips 11b, is cut open, and the product 2 is exposed largely. As is apparent from the figure, the shape of the main body 11 is a flat rectangular shape, and even if there is a wide surface, the main body 11 is divided into a plurality of (individually two) strips 11b and cut open. Can do.

  Therefore, the main body 11 can be opened so as to peel the banana peel, impact can be given to the user, and the image of the product 13 can be improved. Moreover, by opening the longitudinally easy-opening part 15 halfway, it is possible to hold the uncut portion of the main body 11 by hand. For example, the product can be eaten directly like yokan, ice or other food. If you can, you can eat without touching the product, just as you eat bananas. Further, even when the product 13 is taken out to a plate or the like, it is possible to expose almost the whole of the product 13 by tearing it over almost the entire body 11 and dividing it into a plurality of strips 11b. By grasping 11 by hand, one end of the product 13 can be indirectly grasped, and the product 13 can be reliably and easily taken out without being accidentally dropped during opening. Even in this case, the product 13 is not directly touched by hand, which is also hygienic.

  Moreover, since the end seal part 12 is detached from the main body 11 together with the head part 11a by the opening process using the laterally easy opening part 14, in the subsequent opening process using the longitudinally easy opening part 15, the strips are divided. The free end of 11b does not have an end seal portion, and not only looks good, but it is not necessary to make the end seal portion 12 easy to use, so that it can be tightly sealed. Therefore, the seal is not accidentally peeled off at the end seal portion 12, and the sealing performance before the opening operation can be maintained.

  Next, the horizontal direction easy opening part 14 and the vertical direction easy opening part 15 are demonstrated. In this embodiment, a laminated film obtained by laminating a plurality of predetermined film materials as a packaging film constituting the main body 11 is used, and a predetermined position of the film on the outer layer side (the easy opening portion 14 in the horizontal direction and the easy opening portion 15 in the vertical direction). A scar group is formed in the (formation region), and the scar group is easy to open (cut). This scar group is called a so-called magic cut, and can be opened from anywhere in the portion where the magic cut is formed, and is adopted as one of the easy opening functions at the opening start position of the package. In a normal use mode of this magic cut, a layout structure is employed in which a predetermined number of lines are connected so that a line connecting scars extends in the vertical direction (parallel to the center seal portion), and an arbitrary side edge in the vertical direction is used. The film is torn laterally from the position and opened.

On the other hand, in this embodiment, the line which connects a scar is formed so that it may extend in the horizontal direction parallel to the end seal part 12 instead of the normal usage mode of the magic cut. Since it is in the horizontal direction, the magic cut is formed so as to make a round around the cylindrical main body 11. And although it is different from the original usage method, the film is torn along the scars extending in the lateral direction constituting the magic cut. That is, the line of scars extending in the lateral direction constituting the magic cut constitutes the lateral easy-opening portion 14. Further, the one end side is opened by being cut along the scar constituting the magic cut as described above. If there is a half-cracked portion of the scar that makes up the magic cut, or if there are multiple scars, an uncut scar remains, which is the original method of using magic cut. Cut in the direction perpendicular to the line connecting the scars and cut in the vertical direction. Therefore, the normal functional part of the magic cut formed so as to extend in the horizontal direction constitutes the vertical easy-opening portion 15. As described above, the magic cut formed in the direction rotated 90 degrees from the normal direction has the functions of both the easy opening portion 14 in the horizontal direction and the easy opening portion 15 in the vertical direction.

  By the way, the scars that make up the magic cut are very fine and it is difficult to recognize the position of the scars even if they are seen with the naked eye. Therefore, in this embodiment, as shown in FIG. 3, the design is such that the magic cut, that is, the positions where the laterally easy opening part 14 and the longitudinally easy opening part 15 exist can be easily understood. Specifically, as shown in FIG. 3A, the magic cut formation region MR is formed into a strip having a certain width, and the formation region MR is divided into two in the vertical direction. The two divided regions are referred to as a first region R1 and a second region R2 in order from the end seal portion 12 side for convenience. In this case, the first region R1 becomes the laterally easy opening portion 14, and the second region R2 becomes the longitudinally easy opening portion 15. In the formation region MR, the scar group constituting the magic cut is formed in the same manner at any location, and is not particularly different between the first region R1 and the second region R2. Therefore, when cut in the horizontal direction at an arbitrary position in the first region R1, the scar group constituting the magic cut in the first region R1 remaining on the main body 11 side can be cut in the vertical direction from any position. It can function as a magic cut and functions as the easy opening portion 15 in the vertical direction.

  In order to easily understand the positions of the regions R1 and R2, when printing is performed on the packaging film constituting the main body 11, the first and second regions R1 and R2 have different design patterns. With different design patterns, the color may be changed or the pattern may be changed. Also, it is preferable to print a message such as “Please cut in the horizontal direction” in the first region R1 because the meaning of the region is easier to understand.

  By doing so, the user can recognize the location of the first region R1, cut the packaging film of the main body 11 in the lateral direction, and cut and open the head portion 11a including the end seal portion 12 without hesitation. . Then, it can divide | segment into several strips and can cut open by cutting in the vertical direction from the arbitrary site | parts which the main body 11 opened.

  Even when the position that has entered the second region R2 side is cut off in the horizontal cutting, it is often near the boundary by using a different pattern. In this case, the magic of the second region R2 Since many of the cut scars remain, it can be easily cut in the vertical direction.

  Also, printing is performed so that only the first region R1 or only the second region is filled with a predetermined color / pattern, and the other region is not subjected to a special design (same as the ground pattern of the main body 11). May be. For example, when a predetermined design is applied only to the first region R1, the laterally easy opening portion 14 is formed at any position in the design, and the head portion 11a can be excised by tearing the film laterally at an arbitrary position. Even if the edge on the second region side of the designed region is cut off, the magic cut in the second region R2 remains in the portion remaining on the main body 11 side. Can be easily torn.

  Moreover, when a predetermined design is applied only to the second region R2, the head portion 11a can be easily removed by tearing in the lateral direction along the end edge on the end seal portion 12 side of the design, and the pillow package 10 can be removed. Can be opened. In this case, it is not necessary to cut accurately on the edge. That is, even if it is outside the design, since there is a group of magic cut scars in the first region R1, the film can be torn in the horizontal direction. Since many of the magic cut scars in the region R2 remain, it can be easily cut in the longitudinal direction thereafter. In addition, since the cutting position in the horizontal direction based on the pattern differs depending on which region is provided with the pattern, it is necessary to know which one is used.

  FIG. 3B shows another example. In this example, a cut guide line 11c is formed on one side edge of the magic cut formation region MR. The cut guide line 11 is formed by a predetermined length in the lateral direction from the side edge. Further, in order to make the formation position of the cut guide line 11c conspicuous, the portion of the surrounding region R3 may be painted with a color different from the surroundings. Further, the cut guide line 11c can be formed by cutting in a straight line continuous with a part of the outer layer of the laminated film. The formation position of the cut guide line 11c can be any position in the magic cut formation region MR, but is preferably a half region close to the end seal portion 12 side, and more preferably within that region. This is because the side is closer to the end seal portion. However, too much edge is not preferable because there is a possibility that it cannot be cut well in the lateral direction.

  Thus, the user can easily cut the film laterally from the cut guide line 11c. The subsequent longitudinal cutting process is the same as described above. Further, the cutting guide line 11 may completely cut the film like a so-called I notch. In that case, the region R3 may be sealed to ensure hermeticity.

  FIG. 3C shows still another example. In this example, a linear mark line 11d extending in the horizontal direction is formed by printing. Thereby, the user can understand that what is necessary is just to tear a film along the mark line 11d. The mark line 11d is merely an approximate mark, and there is no problem even if the position shifted from the mark line 11d is cut in the horizontal direction, as described in the example of FIG. That's right.

  Further, as shown in FIG. 3D, the mark line indicating the cutting position in the horizontal direction does not need to be formed over the entire length in the horizontal direction, and the shape is not limited to a straight line. For example, as shown in FIG. 3D, an arrow-shaped mark line 11e may be used. Naturally, the same mark line 11e, the first region R1, the cut guide line 11c, and the mark line 11d are all provided at positions where the longitudinal easy-opening portion 15 remains.

  FIG. 4 shows another configuration of the laterally easy opening part 14 and the longitudinally easy opening part 15. In the example shown in FIG. 4, a predetermined pattern of cutting lines is used instead of a large number of fine scar groups such as a magic cut as described above. As an example, the cutting line in FIG. 4A is provided with circular patterns P1 ′ at appropriate intervals on a linear pattern P1 extending in the horizontal direction. By forming the predetermined pattern cutting lines on the outer layer side of the multi-layer laminated film, airtightness can be secured. Of course, when airtightness is not required, it does not preclude providing a cutting line that penetrates the packaging film inside and outside.

  Thereby, the linear pattern P1 comprises the horizontal direction easy-opening part 14, and it cuts and opens to a horizontal direction along the linear pattern P1. As a result, a half-circle portion of the circular pattern P1 ′ is left at the open end after opening, and the half-circle portion enters the main body 11 more than the position of the linear pattern P1. Therefore, the semicircular portion exhibits the same function as the V notch, and constitutes a starting portion when the main body 11 (wrapping film) is cut in the vertical direction, that is, the vertical easy-opening portion 15. Therefore, the film can be cut in the vertical direction from an arbitrary position in the plurality of semicircular portions and divided into a plurality of strips.

  Further, as shown in FIG. 4B, the laterally easy-opening portion 14 and the longitudinally easy-opening portion 15 can be configured by arranging L-shaped patterns P2 in the lateral direction. That is, the horizontal line portion P2 ′ constituting the L-shaped pattern P2 is arranged in a straight line, and the vertical line portion P2 ″ extending on the opposite side to the end seal portion 12 is positioned at one end of the horizontal line portion P2 ′. As a result, the horizontal line portion P2 'becomes the horizontal easy-opening portion 14 and the vertical line portion P2 "constitutes the vertical easy-opening portion 15, so that the horizontal line portion P2' (laterally easy-opening portion 14) first follows. The main body 11 is cut in the horizontal direction and opened, and the main body 11 extends along the vertical line portion P2 ″ (vertical easy-opening portion 15) from any position among the plurality of vertical line portions P2 ″ facing the opening. Can be cut vertically and divided into a plurality of strips.

  Furthermore, as shown in FIG. 4 (c), the laterally easy opening portion 14 and the longitudinally easy opening portion 15 can be configured by arranging the circular patterns P3 close to each other so as to be aligned in a straight line. In this way, the plurality of circular patterns P3 become perforated, and when a force is applied so as to cut from the side edge of the main body 11 in the vicinity of the circular pattern P3, the adjacent circular patterns P3 are gradually cut. As a result, the main body 11 is cut laterally and opened. And, since the opened portion has a form in which the semicircular portion of the remaining circular pattern P3 is cut into the main body 11 as in FIG. 4A, the portion has the same function as the V notch. The main body 11 can be cut in the vertical direction from the circular pattern P3. Therefore, the entire circular pattern P3 aligned in the horizontal direction becomes the horizontal easy-opening portion 14, and each circular pattern P3 becomes the vertical easy-opening portion 15. Further, as shown in the drawing, by providing a circular pattern P3 connecting the circular pattern P3 in the vicinity of the side edge of the main body 11 and the side edge, the circular pattern P3 is smoothly cut from the side edge. Can do.

  Furthermore, as shown in FIG. 4D, T-shaped patterns P4 can be arranged in the horizontal direction. That is, the horizontal line portion P4 ′ constituting the T-shaped pattern P4 is arranged in a straight line, and the vertical line portion P4 ″ extending on the opposite side to the end seal portion 12 is positioned at one end of the horizontal line portion P4 ′. As a result, the horizontal line portion P4 ′ becomes the horizontal easy-opening portion 14 and the vertical line portion P4 ″ constitutes the vertical easy-opening portion 15. Therefore, the horizontal line portion P4 ′ (laterally easy-opening portion 14) is first aligned. The main body 11 is cut and opened in the horizontal direction, and the main body 11 extends along the vertical line portion P4 ″ (vertical easy-opening portion 15) from an arbitrary position among the plurality of vertical line portions P4 ″ facing the opening. Can be cut vertically and divided into a plurality of strips.

  Each pattern example described above is an example, and the present invention is not limited to this. For example, the circular patterns P1 and P3 ′ may be quadrangles (squares, rhombuses, etc.) whose diagonals are positioned in the vertical and horizontal directions, and other various patterns may be adopted.
