Description

  The present invention relates to an integrated packaging body in which a plurality of articles are packaged in an integrated state with a cylindrical heat-shrinkable film, and a heat-shrinkable film for the integrated packaging.

  An integrated package in which a plurality of articles are packaged in an integrated state with a cylindrical heat-shrinkable film is known. The integrated package is a package in which a plurality of articles are packaged together using the shrinkage force when the heat-shrinkable film is thermally shrunk.

  However, when the heat-shrinkable film is thermally shrunk, the opening edge portion is hard and has an edged state, so that there is a problem that the touch feeling when the opening edge portion is touched by hand is not good. The present applicant has already proposed a device for preventing wrinkles and distortion from occurring at the opening edge as in Patent Document 1 described below, but as a result of the heat shrinking of the opening edge neatly, a good aesthetic appearance is obtained. On the other hand, the opening edge is in a state where the edge stands clean, and there is room for improvement in tactile sensation when touched by hand.

Utility Model Registration No. 2504195

  Therefore, the present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide an integrated package and a heat-shrinkable film for integrated packaging that can improve the touch of the opening edge.

  The present invention has been made to solve the above-mentioned problems, and the integrated package according to the present invention is an integrated package in which a plurality of articles are packaged together with a cylindrical heat-shrinkable film. A tactile sensation buffer portion deformed so as to soften the tactile sensation by heat shrinkage is formed at the opening edge of the shrinkable film.

  In the integrated packaging body having such a structure, a plurality of articles are packaged collectively by the shrinkage force when the heat-shrinkable film is thermally shrunk, but at the opening edge of the heat-shrinkable film. Since the tactile sensation buffer portion is formed, the touch when the opening edge is touched with the hand is eased.

  In particular, it is preferable that both opening portions of the heat-shrinkable film are located on the sides and are configured as hand-carrying mouth portions, and a tactile cushioning portion is formed at least at the upper part of both opening edge portions of the heat-shrinkable film. When the opening of the heat-shrinkable film is configured as a hand opening as in this configuration, for example, the left and right hands are inserted into the opening and the hands are caught on the opening edge. You can carry your body. And since the tactile-feel buffer part is formed in at least the upper part among the perimeters of the opening edge part, the touch at the time of hooking a hand to an opening edge part is eased, and an integrated package body can be carried easily.

  Furthermore, it is preferable that a curled portion curled outward or inward is formed as the tactile sensation buffer portion. Since the curled portion is formed at the opening edge, a soft hand can be obtained as compared with a state where the edge is raised, and the strength of the opening edge is improved.

  Furthermore, it is preferable that the shrinkage suppression layer is formed only on one of the front surface and the back surface of the opening edge, and the curled portion is curled toward the surface where the shrinkage suppression layer does not exist. For example, when a shrinkage suppression layer is formed only on the back surface of the opening edge, thermal shrinkage on the back surface side is suppressed as compared to the front surface, and as a result, a curled portion curled outward is formed on the opening edge. Is done. In addition, when a shrinkage suppression layer is formed only on the surface of the opening edge, thermal shrinkage on the front side is suppressed as compared with the back side, and as a result, a curled portion curled inward is formed on the opening edge. Is done. In any case, the curl portion can be easily formed on the opening edge by the shrinkage suppression layer formed only on one of the front surface and the back surface of the opening edge. If the shrinkage suppression layer is a printed layer formed by printing, the portion where the curled portion is formed can be easily controlled by the printing method.

  In addition, it is also preferable that a large number of small protrusions that are continuous in the circumferential direction are formed as the tactile sensation buffering portion through a notch opened in a V shape. By forming small protrusions that are continuous in the circumferential direction on the opening edge, the opening edge becomes discontinuous, and the opening edge becomes softer than when the opening edge is linear. The touch feel is improved. Moreover, when opening from an opening edge part, it can open easily from the notch between small protrusion pieces as a starting point.

  The heat-shrinkable film for integrated packaging according to the present invention is a heat-shrinkable film for integrated packaging that is formed into a cylindrical shape so as to package a plurality of articles at once. In addition, a tactile sensation buffer forming portion for deforming the opening edge portion so as to relieve the tactile sensation by heat shrinkage is formed in the portion that becomes the opening edge portion.

  In the heat-shrinkable film for integrated packaging having such a structure, the heat-shrinkable film deforms the opening edge portion where the tactile sensation buffer forming portion is formed so as to soften the tactile sensation. The tactile sensation buffer as described above is formed.

  As described above, in the integrated package according to the present invention, the tactile sensation buffer portion is formed at the opening edge portion, so that the touch of the opening edge portion is compared to the conventional state where the edge stands clean. Can be improved.

  Moreover, in the heat-shrinkable film for integrated packaging according to the present invention, since the tactile sensation buffer forming portion is formed in the portion that becomes the opening edge, the touch of the opening edge is improved in the packaging state.

  Hereinafter, an integrated package according to an embodiment of the present invention and a heat-shrinkable film used therein will be described with reference to FIGS. An integrated package 1 shown in FIG. 1 is one in which canned beverages 2 as articles to be packaged are packaged in a dozen, i.e., twelve, by a cylindrical heat-shrinkable film 3. . The can beverage 2 has a columnar shape and its axis is directed in the vertical direction, and is in a state of being stacked and arranged in a plane without being stacked up and down. Specifically, when the axial direction of the tubular heat-shrinkable film 3 is the vertical direction (arrow A) and the direction orthogonal to the axial direction is the horizontal direction (arrow B), the can beverage 2 is in the vertical direction. It is in a state of being arranged in four rows and three rows in the lateral direction, and is packaged such that the axis of the cylindrical heat-shrinkable film 3 is substantially horizontal. Accordingly, the integrated packaging body 1 has a substantially rectangular parallelepiped shape as a whole, although the surface thereof has irregularities as a result of conforming to the shape of the can beverage 2.

  Both ends of the tubular heat-shrinkable film 3 are open even after heat shrinkage, and the opening portions of the both ends are located on a pair of side surfaces facing each other of the integrated packaging body 1. Since the integrated package 1 has a substantially rectangular parallelepiped shape, the opening is located on the short side surface 1a (the side surface on which three can drinks 2 are arranged) of the two pairs of side surfaces of the integrated package 1. ing. Both side openings of the heat-shrinkable film 3 opened to the side are configured as hand-carrying mouths for holding the integrated package 1 with both hands. The integrated package 1 can be easily transported by being hooked on the upper portions of the edge portions 30. An opening perforation 31 is formed along the direction orthogonal to the axial direction of the heat-shrinkable film 3, that is, along the lateral direction B. The unsealing perforations 31 circulate around the heat-shrinkable film 3 and are formed at positions between adjacent can beverages 2. At the position between the adjacent canned beverages 2, the heat-shrinkable film 3 is mostly not in close contact with the surface of the canned beverage 2, so it is easily opened by forming a perforation 31 for opening at that position. it can. In the present embodiment, since four can beverages 2 are arranged in the vertical direction, opening perforations 31 are formed at a total of three positions. Although this opening perforation 31 may be a single line, in this embodiment, three lines are formed at each location. By forming a plurality of perforations 31 for opening as described above, it is possible to reduce the influence of the positional deviation of the heat-shrinkable film 3 with respect to the can beverage 2, and among the perforations 31 for opening a plurality of strips Any one will surely be located between the cans 2 and can be opened easily. In addition, although the perforation 31 for opening was formed in each of a total of three positions between adjacent can drinks 2, it is not necessary to form in all three positions.

  In both the opening edge portions 30 of the heat-shrinkable film 3, tactile sensation buffer portions that are deformed so as to soften the tactile sensation by heat shrinkage are formed. Specifically, as shown in an enlarged cross-sectional view in FIG. 2, curled portions 32 in which the heat-shrinkable film 3 is curled outward are formed at both opening edge portions 30 as tactile cushioning portions. The curled portion 32 has a folded width W of, for example, about several millimeters to several tens of millimeters, and is about 2/3 of the upper side of the entire circumference of the opening edge 30 except for about 1/3 of the lower side. Is formed. More specifically, the heat-shrinkable film 3 has a so-called printing layer 34 in which the printing layer 34 is laminated only on the back surface of the base film 33 and the printing layer 34 is not formed on the surface of the base film 33 as shown in FIG. This is a back printed film. The print layer 34 is composed of a design layer composed of characters and figures laminated on the back surface of the base film 33 and a white solid layer laminated on the back surface of the design layer. Is transparent so that at least the design layer on the back side can be seen from the front side. Since the printing layer 34 is formed up to both opening edges 30, and the printing layer 34 at the opening edge 30 suppresses thermal shrinkage on the back side of the base film 33 as a shrinkage suppression layer, there is a shrinkage difference between the front and back sides. As a result, the heat-shrinkable film 3 curls outward at the opening edge 30 thereof. The printed layer 34 is not formed on the entire circumference of the heat-shrinkable film 3, but is formed in an upper region of about 2/3 of the entire circumference. In FIG. 1, a line indicated by reference numeral 35 is a boundary line between a region where the print layer 34 is formed and a region where the print layer 34 is not formed. The region where the print layer 34 is formed and the region where the print layer 34 is not formed both exist from one opening edge 30 to the other opening edge 30. In this way, the printed layer 34 covers the entire three surfaces of the upper surface 1c and the long side surface 1b of the integrated package 1, and the center of the lower portion and the lower surface of the short side surface 1a of the integrated package 1. This area has no print layer 34. Since the printing layer 34 is formed in the upper 2/3 region of the entire circumference of the heat-shrinkable film 3, the curled portion 32 of the opening edge 30 is also opened in accordance with the formation region of the printing layer 34. While formed in the upper region of the edge portion 30, the curled portion 32 is not formed in the lower portion of the opening edge portion 30.

  FIG. 3 shows a cylindrical heat-shrinkable film 3 in a state before heat-shrinking. In FIG. 3, the hatched area is an area where the print layer 34 is formed, and the unhatched area is an area where the print layer 34 is not formed. That is, the print layer 34 is formed from one end to the other end along the axial direction of the heat-shrinkable film 3, and the region where the print layer 34 is not formed is also formed from one end along the axial direction of the heat-shrinkable film 3. Exists to the other end. Since the printing layers 34 are formed up to both opening edges 30 of the heat-shrinkable film 3, the printing layers 34 at both opening edges 30 function as a shrinkage suppression layer and heat on the back side of the base film 33. As a result of suppressing the shrinkage, the heat-shrinkable film 3 curls outward at the opening edge 30 thereof. In the present embodiment, the printed layer 34 on the back surface of the opening edge 30 forms a tactile sensation buffer forming portion. In addition, since both opening edge parts 30 are located in the side surface 1a of the short side of the accumulation | storage package 1 after heat contraction, the length of the axial direction of the heat-shrinkable film 3 before shrinkage | contraction is the accumulated can drink 2 The length of the heat shrinkable film 3 is longer than the entire length in the vertical direction by a predetermined length and protrudes from the can beverage 2 in which both ends of the heat shrinkable film 3 are accumulated. The opening perforation 31 described above is formed in parallel with the opening edge 30.

  The cylindrical heat-shrinkable film 3 is formed from an original fabric roll 11 in which a long heat-shrinkable film 10 is wound into a roll shape as shown in FIG. On the back surface of the long heat-shrinkable film 10, printing layers 34 are formed at regular intervals in the longitudinal direction, and there is no printing layer 34 between the printing layers 34 and 34. Region 12 exists. In FIG. 4, the hatched area is the area where the print layer 34 is formed. The printed layer 34 is formed over the entire width of the long heat-shrinkable film 10, and the unprinted region 12 also exists over the entire width. Then, the long heat-shrinkable film 10 is cut from the raw fabric roll 11 for each predetermined length while the unprinted region 12 is set as a cut position while the long heat-shrinkable film 10 is fed out. A position indicated by a one-dot chain line C in FIG. 4 is a cutting position. The sheet-like heat-shrinkable film 13 formed by this cutting is formed into a cylindrical shape as shown in FIG. In FIG. 3, a portion indicated by reference numeral 14 is an overlapping portion, and the overlapping portion 14 is located on the lower surface of the integrated packaging body 1 although not shown in FIG. 1.

  Here, as the base film 33 of the heat-shrinkable film 3, for example, a biaxially stretched film having various heat-shrink properties such as a polyester film, a polystyrene film, and a polyolefin film can be used. In addition to the above, it may be a multilayer. The printing layer 34 is formed by, for example, gravure printing, and acrylic ink is preferably used for the design layer, but various gravure inks such as urethane-based ones can be used. The ink may or may not contain a pigment, and may be a UV curable ink. The white solid layer is composed of one layer or two or more layers of white ink mixed with a white pigment such as titanium dioxide, and the white solid layer is also formed by, for example, gravure printing. However, the layer configuration of the printing layer 34 is arbitrary, and is not limited to the one including both the design layer and the white solid layer, and may include only the design layer or the white solid layer, or may include three or more layers. It is good.

  The integrated packaging body 1 configured as described above is easy to manufacture because a plurality of articles can be packaged collectively using the shrinkage force of the heat-shrinkable film 3, and packaging materials are also included. Small amount is enough. Further, by providing the heat shrinkable film 3 with the printing layer 34, the display function can be sufficiently exhibited. In particular, since the entire upper surface 1c and both side surfaces 1b on the long side of the integrated package 1 are covered with the printed layer 34, a sufficient design area is ensured and an impactful package design is possible. On the other hand, the cost can be suppressed by providing a region without the print layer 34 on the lower surface of the integrated package 1 that is normally invisible.

  In addition, since both openings of the heat-shrinkable film 3 are open to the side and can be used as a mouthpiece for carrying, for example, left and right hands are respectively inserted into the openings and hands are held at the opening edge 30. It is possible to easily carry the integrated package 1 by hooking it. In particular, since the curled portion 32 is formed on the upper portions of both opening edge portions 30 of the heat-shrinkable film 3, the hand is caught on the opening edge portion 30 as compared with the state where the edge of the opening edge portion 30 stands. The touch is soft and easy to carry. Further, since the curled portion 32 is formed on the opening edge portion 30, the rigidity of the opening edge portion 30 is increased, the strength is improved, and stress concentration at a specific portion of the opening edge portion 30 is reduced. Therefore, even if the weight of the integrated package 1 is large, the heat-shrinkable film 3 can be prevented from being inadvertently torn or torn from the opening edge 30. Moreover, since the region where the curled portion 32 is formed is the upper region where the printing layer 34 is formed on the entire circumference of the heat-shrinkable film 3, a package design having a large area is formed on the upper surface of the integrated packaging body 1. At the same time, the curled portion 32 is formed on the upper portion of the opening edge 30 while ensuring good touch feeling. However, a separate dedicated print layer 34 may be formed as a shrinkage suppression layer only on the opening edge 30 separately from the package design.

  Furthermore, since the print layer 34 is formed only on the back surface of the opening edge 30, the curled part 32 is automatically formed by heat shrinkage, and a separate part for forming the curled part 32 is required. This process is unnecessary. In addition, since the shrinkage suppression layer is the printing layer 34, the formation location of the curled portion 32 can be easily set, and the folded width W of the curled portion 32 can be determined by, for example, changing the thickness of the printed layer 34, the type of ink, and the like. It can be easily controlled by setting.

  In addition, you may provide the printing layer 34 also on the surface of the base film 33 like FIG. The printing layer 34 on the surface can be a varnish layer, and a region without the printing layer 34 is formed on the surface of the opening edge 30 without providing the printing layer 34 on the surface up to the opening edge 30. In this way, even when the printing layer 34 is formed on the surface of the base film 33, the printing layer 34 is not provided on the surface of the opening edge 30, so that only the printing layer 34 on the back surface is provided at the opening edge 30. Therefore, a curled portion 32 that is curled outward is formed on the opening edge portion 30 in the same manner as described above.

  Further, the opening edge 30 may be curled not on the outside but on the inside. For example, as shown in FIG. 6A, a printing layer 34 similar to that described above is formed on the surface of the substrate film 33, and the printing layer 34 is not provided on the back surface of the substrate film 33. It can be in the form of front printing. In this case, the printing layer 34 may have a three-layer structure of a varnish layer, a design layer, and a white solid layer in order from the front side. In this way, by forming the printing layer 34 only on the surface side of both surfaces of the opening edge 30, the printing layer 34 becomes a shrinkage suppression layer, and the opening edge 30 curls inward, and the curled portion 32 is formed. It is formed. In addition, when a design layer is unnecessary for the heat-shrinkable film 3, the printed layer 34 on the surface shown in FIG. 6A can be composed only of a varnish layer. By forming the printing layer 34 on the surface up to the opening edge 30, the opening edge 30 can be curled inward. Alternatively, the printed layer 34 formed of the varnish layer may be formed only on the opening edge 30 instead of the entire surface of the base film 33 so that the opening edge 30 is curled inward.

  Furthermore, as a configuration for curling inward, for example, when the printing layer 34 is formed on both the front surface and the back surface of the base film 33 as shown in FIG. 6B, the printing layer 34 on the back surface side is opened. While not forming up to the edge 30, the printing layer 34 on the front side may be formed up to the opening edge 30. As an example, the printed layer 34 on the back surface is composed of a design layer and a white solid layer, and the printed layer 34 on the front surface is composed of a varnish layer in order to achieve the above-described back printing mode. As another example, a design layer may be provided on the printing layer 34 on the front surface so that the front printing mode is used, and the printing layer 34 on the back surface may be used as a light shielding layer. The light-shielding layer preferably has a multilayer structure rather than a single-layer structure. For example, one or two or more black layers composed of a black ink blended with a black pigment such as carbon black and a white pigment such as titanium dioxide are blended. It is composed of a single layer of white ink or two or more white layers. In the case of FIG. 6B as well, the printing layer 34 on the surface can be formed only on the opening edge 30 without providing the entire surface, and this is particularly effective in back printing.

  Although the printing layer 34 is formed as the shrinkage suppression layer on the opening edge 30, the shrinkage suppression layer may be formed by applying ink or the like to the opening edge 30 instead of the printing method. Further, the curled portion 32 may be formed over the entire circumference of the opening edge portion 30, and the length of the curled portion 32 in the circumferential direction can be variously changed. However, it is preferable that the curled portion 32 is provided at least in a region where the hand is caught.

  On the other hand, a shrinkage suppression layer such as a printing layer 34 is formed only on one side of the opening edge 30 of the heat-shrinkable film 3 to form a curled portion 32 that is a tactile shock absorbing portion on the opening edge 30. Various other forms can be adopted. For example, as shown in FIG. 7, a large number of small protrusions 36 may be formed on the opening edge 30 as tactile cushioning portions. The small protrusions 36 have, for example, a width of about 1 mm and a length in the protruding direction of about 1 mm, are formed continuously along the circumferential direction of the opening edge 30, and are formed around the entire periphery of the opening edge 30. It is formed over. In addition, a V-shaped notch 37 is formed between adjacent small protrusions 36, and the small protrusions 36 are continuously provided via the notches 37.

  The cut 37 is formed in a state before the heat-shrinkable film 3 is heat-shrinked. As shown in FIG. 8, a long heat-shrinkable film 10 fed out from a raw roll (not shown) is cut at a predetermined position to form a single-wafer heat-shrinkable film 13. In this state, that is, in a state before being wound in a roll shape, cuts 37 may be continuously formed at predetermined pitches on both side edges in advance, or a long heat-shrinkable film may be formed from the original roll. The cuts 37 may be sequentially formed at both side edges while the 10 is fed out. In any case, since both side edges of the sheet-type heat-shrinkable film 13 are portions that become both opening edges 30 when being formed into a cylindrical shape, a large number of cuts 37 are formed on both side edges. Keep it. The large number of cuts 37 constitute a tactile sensation buffer forming portion. Then, when the heat-shrinkable film 3 is heat-shrinked so as to wrap the canned beverage 2 in an accumulated state, the notches 37 open in a V shape, so that a large number of the opening edges 30 are provided via the V-shaped notches 37. The small protrusions 36 are continuously formed. That is, the notch 37 in the opening edge 30 is automatically deformed into a V shape when the heat-shrinkable film 3 is thermally contracted, so that the V-shaped notch 37 is formed in the opening edge 30 after the heat shrinking. You don't have to.

  When a large number of small protrusions 36 are formed on the opening edge 30 as described above, the opening edge 30 becomes discontinuous in the circumferential direction. In the case where there is no small protrusion 36, the opening edge 30 is continuous in the circumferential direction, and the edge is standing due to thermal contraction and is hard and uncomfortable to touch. When the opening edge 30 is discontinuous by a large number of small protrusions 36, the tactile sensation of the opening edge 30 is softer than in the continuous state. In particular, the heat shrinkable film 3 is thermally shrunk so that the notches 37 are opened in a V shape. Therefore, the length of the discontinuous portion between the adjacent small protrusions 36 is long, and therefore the notches 37 are formed in a V shape. A good touch feeling can be obtained as compared with a non-open form. Further, since the small projecting piece 36 is trapezoidal and not triangular, the tip portion thereof is not sharp, so that the touch is good. In addition, when a hand is applied to the opening edge 30, the small protrusion 36 at that portion bends or bends inward or outward, and the touch is softer than when the edge is standing. Moreover, when opening from the opening edge part 30, it can open easily from the notch 37 opened in V shape as a starting point. In addition, although the small protrusion 36 was formed over the perimeter of the opening edge part 30, it is preferable to provide at least the upper part of the opening edge part 30. FIG.

  It should be noted that the curled portion 32 may be formed at the opening edge 30 and a plurality of small protrusions 36 may be formed. Moreover, although the form which utilizes the opening edge part 30 as a mouth part for carrying is demonstrated, it is applicable also to the form where the opening edge part 30 is located up and down, for example.

  The number and arrangement of can beverages 2 are arbitrary, and may be, for example, vertically stacked or stacked, and can of course be applied to articles other than can beverage 2, such as pets of various sizes. It may be a bottled beverage or a beverage in a box-shaped container, canned food, detergent, etc., and can be applied to articles of various types, sizes and shapes. Furthermore, it may be an accumulation of a plurality of types of articles instead of an accumulation of one kind of articles.
