  By the way, a seal-type label in which an adhesive layer is formed on the back surface is expensive. For this reason, the point that a package becomes expensive as a result is pointed out.

  In view of such circumstances, an object of the present invention is to provide a low-cost package including a label and a manufacturing method for manufacturing a low-cost package.

  The package of the present invention includes a package body and a label, and the package body is formed of a packaging laminate film having an inner surface as a weld layer and an outer surface as a non-weld layer, and at both end portions in the length direction. At least one of the end portions is formed in a bag shape by thermally welding the opposing inner surfaces, the label is formed from a laminate film for a label having an inner surface as a welding layer and an outer surface as a non-welding layer, The label has a length equal to the length between both ends of the packaging body and a width smaller than that of the laminate film for packaging, and the outer surface of the packaging body is overlapped between both ends of the packaging body. It is characterized by being welded to.

  In the package having the above structure, the laminate film for label is adhered to the outer surface of the laminate film for packaging so that the laminate film for label is stuck as a label. It becomes cheaper than the package.

  In the package of the present invention, the label may be formed in a strip shape having a width smaller than the width of the package body, which is a direction orthogonal to the length direction of the package body. By making the label a width smaller than the width of the package body, it is possible to further reduce the cost.

  In the packaging body of the present invention, the packaging body main body includes a back tension formed by forming a laminate film for packaging into a cylindrical shape and heat-welding each other with the inner surfaces at both ends in the circumferential direction as mating surfaces, As the label, a configuration in which the label is welded to an area that does not overlap the backrest can be adopted.

  Since the label is welded to a region that does not overlap the back tension like the package having the above configuration, the label is less likely to get in the way when the back is opened by gripping the back tension.

  In the package of the present invention, the label laminate film may employ a structure in which ultrasonic welding is performed in a region between both end portions in the length direction of the package body.

  According to ultrasonic welding, even if it is with respect to the outer surface of the laminate film for packaging, the welding layer of the laminate film for labels can be welded.

  In the package of the present invention, it is possible to adopt a configuration in which the welded portion by the ultrasonic welding is formed in a stripe shape in the middle portion in the width direction of the label laminate film.

  As in the package having the above-described configuration, the welded portion by ultrasonic welding is formed in a streak shape, so that it is easy to control the welding means when performing ultrasonic welding.

  The manufacturing method of the package of the present invention comprises a strip-shaped label laminate film having an inner surface as a weld layer and an outer surface as a non-weld layer on the outer surface of a package laminate film having an inner surface as a weld layer and an outer surface as a non-weld layer. A feeding process in which the inner surface is superposed, a laminating film for laminating the label laminating film superimposed on the laminating film for packaging by the feeding process, and a laminating film for packaging by the welding process At the end of at least one end of the predetermined length region of the tubular body formed by the forming step and the forming step of forming the double film welded to the tubular body, the tubular body is And a bag-making process in which the inner surfaces facing each other are heat-welded.

  According to the manufacturing method of the packaging body, since the laminating film for a label is affixed as a label by welding the welded layer of the laminating film for a label to the outer surface of the laminating film for packaging, the seal-type label is provided. An inexpensive packaging body can be manufactured as compared with the packaging body. Moreover, the laminate film for labels is stacked so as to extend along the length direction of the laminate film for packaging, and the inner surfaces facing each other at at least one of the both ends corresponding to the length of the package body are thermally welded to form the package body. By setting it as a main body, the packaging body provided with the laminate film for labels as a label can be manufactured continuously.

  In the manufacturing method of the package of this invention, the method performed by ultrasonic welding can be employ | adopted for a welding process. According to ultrasonic welding, even if it is with respect to the outer surface of the laminate film for packaging, the welding layer of the laminate film for labels can be welded.

  The package of the present invention includes a label and is inexpensive, and according to the method for manufacturing the package of the present invention, a package including the label and inexpensive can be continuously manufactured.

The Specifically, the second roll 16 is disposed closer to one side of the first roll 14 in the axial direction. Note that the second roll 16 is disposed so as not to reach the axial end of the first roll 14. As will be described later, this positional deviation amount is positioned in a region where the second film 6 does not overlap the vertical seal portion (corresponding to the backrest described in FIG. 4) 4A of the package body 3A.

  The homer 8 is arranged in the middle of the transport path S of the article 2 to be packaged, and the configuration thereof is general, so the description thereof is omitted. The first welded portion 10 is a portion that is disposed on the downstream side with respect to the homer 8 and forms the vertical seal portion 4 </ b> A on the first film 4. The second welded portion 12 is disposed on the downstream side with respect to the first welded portion 10, and forms the horizontal seal portions 18 at both ends of the predetermined length region of the cylindrical body 9, and both the horizontal seal portions. 18 is a part that cuts 18 in the width direction and includes the article 2 to be packaged in the cylindrical body 9 introduced from the upstream side of the transport path S. The second welded portion 12 includes a pair of upper and lower heaters 12A and 12B and a cutter (not shown) (for example, a blade that melts the film with heat).

  As shown in FIG. 1, on the downstream side of the first delivery unit 5 and the second delivery unit 7, a first tension roller 19 for applying tension to the first film 4 and the second film 6, respectively, and a second tension A roller 20 is disposed on the downstream side of the first tension roller 19 and the second tension roller 20 and is commonly used for the first film 4 and the second film 6 to apply tension to the films 4 and 6. A plurality of three tension rollers 21 are arranged.

  The label welding part 13 is disposed between the two third tension rollers 21. That is, the label welding part 13 is arrange | positioned with respect to the 2nd welding part 12 in the delivery direction upstream of the 1st film 4. FIG. The label welding part 13 welds the 2nd film 6 to the 1st film 4 using an ultrasonic wave. The label welding part 13 includes a horn 22 having a general configuration and functions and a cradle 23. The horn 22 and the cradle 23 are disposed at the opposing positions. In the present embodiment, the horn 22 is disposed on the second film 6 side, and the cradle 23 is disposed on the first film 4 side.

Next, a packaging method for packaging the article 2 using the packaging apparatus 1 having the above configuration will be described. This packaging method
(1). A sending step of sending the first film 4 by the first sending unit 5 and sending the belt-like second film 6 to the outer surface 4a along the longitudinal direction L of the first film 4 by the second sending unit 7;
(2). A first forming step of forming the first film 4 into a cylindrical shape by the homer 8;
(3). The first film 4 formed into a cylindrical shape by the first welded portion 10 is heat-welded with the inner surfaces of both end portions in the circumferential direction as mating surfaces, and the vertical seal portion 4A is formed at the substantially central portion in the width direction of the package body 3A. A second molding step for making the cylindrical body 9 by
(4). A package body in which the article to be packaged 2 is installed by thermally welding the inner surfaces facing each other at both end portions of the predetermined length region of the cylindrical body 9 by the second welded portion 12 to form a lateral seal portion 18. A third molding step of forming 3A and cutting the transverse seal portion 18 at the central portion in the longitudinal direction to individually package the article 2;
(5). The label welding portion 13 on the upstream side in the delivery direction of the first film 4 with respect to the second welding portion 12 causes the outer surface 4a of the first film 4 to be inserted between both end portions corresponding to the length of the package body 3A. A welding process in which two films 6 are welded to form a double film W;
Is provided.

  In the delivery step (1), the first film 4 is sent to the downstream side by driving the first delivery unit 5, and the belt-like second is smaller in area than the first film 4 by driving the second delivery unit 7. The film 6 is fed out so as to overlap the second film 6. Based on the configuration in which the second roll 16 is displaced in the axial direction with respect to the first roll 14 during this delivery step, the position of the second film 6 relative to the first film 4 is the second The film 6 is positioned so as not to overlap the vertical seal portion 4 </ b> A of the package body 3 </ b> A, and the second film 6 is positioned so as not to reach the width direction end of the first film 4.

  Both the first film 4 and the second film 6 are laminate films, and in the sending process, the first film 4 is sent out with the welding surface as the back side facing down. The second film 6 is also sent out with the welding surface, which is the back surface, facing down. That is, in the second film 6, the welding surface that is the inner surface is superimposed on the non-welding surface that is the outer surface 4 a of the first film 4.

  In the packaging method in the present embodiment, in the sending step (1), the second film 6 is overlapped on the first film 4 and sent out. In the first molding step (2), the stacked first film 4 and second film 6 are both introduced into the homer 8, and only the first film 4 is the first film 4 and the second film 6. Molded to be cylindrical. In the second molding step (3), only the first film 4 is processed in a state where the second film 6 is superimposed on the first film 4. In the third molding step (4), the first film 4 and the second film 6 are overlaid.

  In particular, in the third molding step, the first film 4 is pressed by the heaters 12A and 12B of the second welded portion 12, heated by the heaters 12A and 12B, and at both ends of the predetermined length region of the cylindrical body 9. The welding surfaces which are the inner surfaces facing each other are thermally welded to form the horizontal seal portion 18. This process corresponds to a bag making process. Moreover, the horizontal seal | sticker part 18 is cut | disconnected with a cutter, and the cylindrical body 9 is formed in 3A of bag-shaped package bodies.

  In the third molding step, the welding surface of the second film 6 superimposed on the first film 4 is also melted by the heat of the heaters 12A and 12B. However, as described above, the welding surface of the second film 6 is overlapped with the non-welding surface, which is the outer surface 4a of the first film 4, so that the welding surface of the second film 6 is formed by the second welding portion 12. Even if heat-melted, it is not firmly welded to the outer surface 4a of the first film 4. In addition, the cut | disconnected vicinity of the welding surface of the 2nd film 6 is not welded.

  On the other hand, in the present embodiment, the second film 6 includes a welding process in which the second film 6 is ultrasonically welded to the first film 4, and this welding process is performed prior to the third forming process of (4). ing. The welding process is performed between the delivery process (1) and the first molding process (2). In other words, the second film 6 is welded before the third molding step (4). For this reason, regardless of the presence or absence of the third formation step (4), and even if the welding surface of the second film 6 is superimposed on the non-welding surface that is the outer surface 4a of the first film 4, By the ultrasonic welding, the second film 6 reaches the third molding step in a state where the second film 6 is firmly welded to the first film 4.

  In the present embodiment, after the first film 4 is made into the cylindrical body 9 (after the second molding step), before being made into the package body 3A (before the third molding step), it is to be packaged. There is a charging step in which the object 2 is charged into the cylindrical body 9 from the upstream side.

  In the present embodiment, the position of the welded portion 6b that is ultrasonically welded in the welding step (5) is the middle portion in the width direction of the second film 6. The middle part in the width direction in this case is a position that is slightly displaced from the one side edge of the second film 6 to the other side edge, as shown in FIGS. The location of the welded portion 6b to be ultrasonically welded is a portion corresponding to the entire region between both end portions in the length direction of the package body 3A. The welded surface of the second film 6 is not welded in the vicinity of the cut portion, but the welded portion 6b is formed in the entire region between both end portions in the length direction of the package body 3A.

  That is, ultrasonic welding is continuously performed by the label welding portion 13 together with the feeding of the first film 4 and the second film 6. As a result, at the time when the first film 4 is formed on the package body 3A in the third molding step, the second film 6 is already overlapped and welded to the first film 4, and the second film 6 is the first film 4. At the same time, the label 6A is cut. And the welding part 6b ultrasonically welded is formed in the streak shape so that it may cover the whole longitudinal direction of 3 A of package bodies at the time of the 1st film 4 being formed in the package body 3A.

  If the article to be packaged 2 is packaged using the packaging device 1 according to the present embodiment, the labor of another process such as pasting the advertising label on the package body 3A after forming the package body 3A as in the past is reduced. It is unnecessary. This is because the package 3 manufactured using the packaging device 1 is a bag with a label 6A attached thereto. Therefore, an inexpensive package 3 can be provided.

  Moreover, in the packaging method of the packaging body 3 by this embodiment, the 2nd film 6 is piled up and welded on the 1st film 4, and it is set as the double film W, the double film W is used as the cylindrical body 9, and the length direction The package 3 which is cheap can be continuously manufactured by heat-welding both end portions of the bag.

  The label 6A is not a seal type in which an adhesive layer (pressure-sensitive adhesive layer) is formed on the back side, but a laminate film is used to ultrasonically weld the inner surface to the outer surface 4a of the first film 4. It is. For this reason, the cost required for the label 6A itself is suppressed, and even if the welding surface of the second film 6 is overlapped with the non-welding surface which is the outer surface 4a of the first film 4, the second film 6 is attached. It can be firmly welded to the first film 4.

  In the packaging method in the present embodiment, the second film 6 is attached to a region that does not overlap the vertical seal portion 4A formed before the horizontal seal portion 18 is formed. If the 2nd film 6 is made to overlap with the vertical seal | sticker part 4A, in the 3rd shaping | molding process, in order to form the package body 3A which included the to-be-packaged object 2, the cylindrical body 9 is formed by the 2nd welding part 12. FIG. When the transverse seal portion 18 is formed by thermally welding the inner surfaces facing each other at both ends, the longitudinal seal portion 4A, the transverse seal portion 18 and the second film 6 are overlapped.

  Specifically, the vertical seal portion 4A is formed by the double first film 4, the horizontal seal portion 18 is formed by the double first film 4, and the second film 6 is superposed thereon. A total of five films are stacked. In this state where five films are stacked, it may be necessary to process a part of the second welded portion 12. For example, it may be necessary to cut off some surfaces of the heaters 12A and 12B (components of the second welded portion 12) in contact with the film according to the thickness of the stacked films.

  However, in the packaging method of this embodiment, the 2nd film 6 is affixed on the area | region which does not overlap with the vertical seal | sticker part 4A. For this reason, when forming the horizontal seal | sticker part 18 with the 2nd welding part 12, it is not necessary to process the 2nd welding part 12 specially. Further, since the second film 6 is welded before the charging step in which the packaged object 2 is loaded into the cylindrical body 9 from the upstream side, the three-dimensional shape of the packaged object 2 is the same as that of the second film 6. There is no hindrance to the welding, that is, the welding of the label 6A.

  The present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention. The same applies to the specific configuration of each part. In the said embodiment, the welding part 6b by ultrasonic welding is a part in the width direction in the 2nd film 6, and is a part corresponded to all the area | regions between the both ends of the length direction of 3 A of package bodies. Was illustrated.

  However, as shown in FIGS. 6 to 8, the welded portion 6b of the label 6A by ultrasonic welding is not a portion corresponding to the entire region between both ends in the longitudinal direction of the label 6A, but only both ends in the longitudinal direction. Further, it may be formed along the width direction. In order to form the welded portion 6b in this way, it is possible to control the timing of driving the label welded portion 13 in accordance with the length of the package body 3A set in advance in the welding process. In addition, the welding part 6b in the embodiment of FIGS. 6 and 7 is slightly displaced in the longitudinal direction with respect to the end of the label 6A (the position where the lateral seal portion 18 is cut in the width direction). This is because it is difficult to match the welded portion 6b to the position where the horizontal seal portion 18 is cut in the width direction in terms of the driving timing of the label welded portion 13. However, there is no problem with the configuration in which the label 6A is firmly welded to the package body 3A even in this form.

  Furthermore, if another form which can be changed about the position and location of the welding part 6b is described, as shown in FIG. 9, it may be formed at predetermined intervals in the longitudinal direction of the label 6A. In the form shown in FIG. 9, the welded portions 6 b are not formed at the end portions in the longitudinal direction of the label 6 </ b> A but are formed at predetermined intervals in the middle portions in the longitudinal direction.

  Further, in FIGS. 2 and 3, the welded portion 6 b of the label 6 </ b> A by ultrasonic welding is formed in a single streak pattern near one side in the width direction of the portion corresponding to the entire region between both ends in the longitudinal direction of the label 6 </ b> A. The case where it formed so that it might become was illustrated. However, the welded portion 6b can also be formed in parallel and a pair of streaks on one side and the other side in the width direction of the portion corresponding to the entire region between both ends in the longitudinal direction of the label 6A. Moreover, it can also be set as the 3 or more streaky welding part 6b. By doing in this way, the label 6A can be fixed to the package body 3A in a stable state.

  In each said embodiment, the case where the label 6A had a width | variety smaller than the width | variety of the packaging body main body 3A which is a direction orthogonal to the length direction of the packaging body main body 3A illustrated. However, the width of the second film 6 that becomes the label 6A only needs to be smaller than the width of the first film 4 that becomes the package body 3A, and covers the entire surface of the package body 3A and the front and back surfaces of the package body 3A. The structure welded so that 3A of package bodies may be covered by this is also considered. However, as described above, an advertising phrase (an increase appeal phrase, a sale period, etc.), a warning, or the like is printed on the label 6A. For this reason, if the label 6A is large, the printing of the package body 3A is hidden. In such a case, if the transparent second film 6 is used, the printing of the package body 3A can be hidden as much as possible.

  And in the said embodiment, the case where ultrasonic welding was positioned in the area | region which does not overlap with the vertical seal | sticker part 4A was illustrated. However, the second film 6 can be superposed on the first film 4 at a portion to be the vertical seal portion 4A, and the superposed portion can be ultrasonically welded.

  Yet another embodiment is shown in FIG. In the package 3 shown in FIG. 10, a perforated cutting line 3 a that makes it easy to take out the packaged object 2 is formed over the entire length in the middle of the package body 3 </ b> A in the width direction. The label 6A is welded to one side of the package body 3A over the entire length direction of the package body 3A. The position and location of the welded portion 6b in this case are the same as those illustrated in FIGS.

  In each said embodiment, the welding part 6b illustrated the welding by an ultrasonic wave. However, the welded portion 6b can also be welded using a high frequency.

  In each of the above embodiments, in the third molding step, the second welded portion 12 is thermally welded between the inner surfaces facing each other at both ends of the predetermined length region of the cylindrical body 9 to form the lateral seal portion 18. Thus, the case where the package body 3A in which the article 2 is packaged is formed and the lateral seal portion 18 is cut at the center portion in the longitudinal direction is exemplified. However, the cutting of the lateral seal portion 18 can be a separate process.

  In the packaging apparatus 1 and the packaging method in the said embodiment, the case where the both ends of the 1st film 4 corresponding to the length of 3 A of package bodies was laterally sealed by the 2nd welding part 12 was illustrated. However, the packaging apparatus 1 is changed to a bag-feeding packaging machine, and only one end of both ends of the first film 4 corresponding to the length of the package body 3A is laterally sealed and the other end is laterally sealed. It is also possible to manufacture a package that allows the other end to be opened.

  In each said embodiment, the case where the vertical seal | sticker part 4A was formed in the width direction approximate center part of 3 A of package bodies was illustrated. However, the packaging device 1 and the packaging method can be modified or applied to the package body 3A in which the vertical seal portion 4A is formed as a side seal on the side portion. Even in this case, the second film 6 can be overlapped with the first film 4 at a portion to be a side seal, and the overlapped portion can be ultrasonically welded.
