DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In this specification and drawings, components having substantially the same functional configurations are designated by the same reference numerals, and redundant description will be omitted.

[0010] FIG. 1 is a diagram showing an example of a tape package according to a first embodiment of the present invention. The tape package 1 is a packaging container 2 filled with tape 3. The packaging container 2 has a cylindrical body 21 with a circular cross section and a bottom 22 provided at one opening of the body 21. The tape 3 is wound around the inner surface of the body 21 on the bottom 22. Each part of the packaging container 2 is formed from, for example, paper such as cardboard or synthetic resin. The body 21 and the bottom 22 may be integrated with an adhesive or the like, or may be separable after use by an engaging structure or the like.

[0011] Figure 2 is a top view of the tape package shown in Figure 1 filled with tape. As shown in the figure, the gap between the outer surface of the tape 3 wound in a substantially cylindrical shape and the inner surface of the body 21 of the packaging container 2 is significantly smaller than when, for example, tape 3 wound with the same outer diameter is filled into the body 21P of a packaging container with a rectangular cross section. This prevents the tape from getting into the gap between the wound tape and the body of the packaging container, allowing the tape 3 to be pulled out of the packaging container 2 more smoothly.

[0012] FIG. 3 is a diagram showing an example of a packaging container for tape according to one embodiment of the present invention. In the packaging container 2 constituting the tape package 1 as shown in FIG. 1, the body 21 and the bottom 22 may be separable. Furthermore, the packaging container 2 may have a lid 23 in addition to the body 21 and the bottom 22. The bottom 22 and the lid 23 are plate-shaped members. Furthermore, the body 21 may also be configured to be foldable, for example, by dividing it into multiple plate-shaped members with arc-shaped cross sections. In this case, after use, the entire packaging container 2 can be disassembled into the plate-shaped members for easy storage and transportation.

[0013] 4 is a diagram showing another example of a packaging container for tape according to an embodiment of the present invention. As shown in the figure, the packaging container 2 may further have a core 24 erected on the bottom 22. In this case, the tape 3 is wound around the core 24. The lid 23 may be connectable to the core 24. In the example shown, the lid 23 is connected to the core 24 by inserting a protrusion 25 provided on the lid 23 into the core 24. A similar connecting structure is provided between the bottom 22 and the core 24, and the core 24 may be removed from the bottom 22 when the tape 3 is pulled out of the packaging container 2. This makes it less likely that the tape 3 will tangle when pulled out.

[0014] FIG. 5 is a diagram showing an example of a tape package according to a second embodiment of the present invention. The tape package 1A is a packaging container 2A filled with tape 3. The packaging container 2A has a cylindrical body 21A with a hexagonal cross section and a bottom 22A provided at one opening of the body 21A. The tape 3 is wound around the inner surface of the bottom 22A and is wound around the inner surface of the body 21A. Each part of the packaging container 2A is made of paper such as cardboard or synthetic resin. The body 21A and the bottom 22A may be integrated with an adhesive or the like, or may be separable after use by an engagement structure or the like.

[0015] The tape package 1A and packaging container 2A according to this embodiment are configured in the same manner as in the first embodiment, except that the cross-sectional shape of body 21A and the shape of bottom 22A are hexagonal. Therefore, the example described above with reference to Figures 3 and 4 can also be applied to this embodiment.

[0016] Even when the cross-sectional shape of the body 21A of the packaging container 2A is a polygon such as a hexagon, the gap between the outer surface of the tape 3 wound in a substantially cylindrical shape and the body 21A is smaller than when the cross-section is rectangular such as the body 21P shown in Fig. 2. This effect can be similarly obtained when the cross-section of the body of the packaging container is a polygon with five or more angles.

[0017] Regarding the cross-sectional shape of the packaging container in the embodiments of the present invention, the gap between the outer surface of the tape wound in a substantially cylindrical shape and the inner surface of the body portion is smaller when the body portion has a circular cross-section, as shown in the first embodiment. However, because the shape of the wound tape is not necessarily a perfect circle, the circular cross-section of the body portion does not need to be a strict circle in geometric terms; it may be any shape that is substantially recognizable as a circle. For example, if the body portion is foldable, the circular shape of the body portion may be flattened during the folding process to form an elliptical cross-section. In this case, the elliptical cross-section does not need to be a strict elliptical cross-section in geometric terms. Even when the body portion has a polygonal cross-section, as shown in the second embodiment, the gap is larger than when it has a circular or elliptical cross-section, but is still useful because it is smaller than when it has a rectangular cross-section. Furthermore, for example, when folding the body portion by dividing it into multiple plate-like members, a polygonal cross-section makes the folded members flat, making storage and transportation easier.

[0018] Furthermore, the packaging container according to the embodiment of the present invention may include components other than the body and bottom, and the lid and core described above. For example, the packaging container may further include an exterior member with a rectangular cross section that circumscribes the body. This exterior member may be, for example, a box that covers the body and bottom from the outside, or may be a cylindrical member like the body. If the exterior member is cylindrical, the bottom does not necessarily have the same shape as the cross section of the body, but may also have the same shape as the cross section of the exterior member. If the packaging container further includes an exterior member with a rectangular cross section, filling the inside of the body with tape, which has a circular, elliptical, or polygonal cross section, enables smooth removal. In addition, the outer shape of the packaging container is a cube or rectangular parallelepiped, which improves stability when lined up or stacked for storage or transportation.

[0019] FIG. 6 illustrates a first example of a method for manufacturing a tape-attached film and a tape-attached bag-shaped container using a tape package according to an embodiment of the present invention. In the three-side bag making machine 300 shown in FIG. 6, the film supply unit 310 unwinds the film 110 wound around the film roll 311 and cuts it widthwise using a cutting blade (not shown) to form the first surface 110A and the second surface 110B. The tape supply unit 320 draws the tape 3 from the tape package 1 and supplies it between the first surface 110A and the second surface 110B using a conveying roll 322 or the like. The seal bar 330 clamps the tape 3 from the outside of the first surface 110A and the second surface 110B and applies heat to bond the tape 3 to the first surface 110A and the second surface 110B, respectively. The seal bars 341 and 342 form bottom seals and side seals between the first surface 110A and the second surface 110B. The cutting blades 351, 352 cut the joined first surface 110A and second surface 110B in the longitudinal direction and width direction, respectively, to cut out the bag-shaped container 100.

[0020] In the three-side bag making machine 300 as described above, a tape-attached film is produced by joining the conveyed tape 3 to the first surface 110A and the second surface 110B of the film by the seal bar 330. Furthermore, the first surface 110A and the second surface 110B of the film to which the tape 3 has been joined are processed into a bag-shaped container body by the seal bars 341, 342 and the cutting blades 351, 352, thereby producing a bag-shaped container with tape.

[0021] FIG. 7 illustrates a second example of a method for manufacturing a tape-attached film and a tape-attached bag-shaped container using a tape package according to an embodiment of the present invention. In the bag-making apparatus 600 shown in FIG. 7, the tape splicing means 610 includes a feeder 611 and seal bars 612A and 612B. The tape 3 drawn from the tape package 1 is cut to a predetermined length and spliced ​​along the width direction of the film 110, which is drawn from a roll (not shown) and transported longitudinally. The tab forming means 620 includes a cutter 621 and a receiving table 622 and forms a tab for opening by a slit 151 that penetrates the film 110 and the tape 3. The rear seal forming means 640 includes a core 641, a transport belt 642, and a sealing device 643. The rear seal forming means 640 rolls both widthwise ends of the film 110 into a cylindrical shape and forms a rear seal, thereby forming the general shape of the container body. The top / bottom seal forming means 650 includes seal bars 651A, 651B, a cutter 652 and a receiving table 653, and forms a top seal portion and a bottom seal portion in the film 110 folded over on both sides in the width direction, and cuts the film 110 in the width direction to form a bag-shaped container.

[0022] When filling of contents is also performed using bag making apparatus 600, filling device 601 is inserted from above into core 641, which has been made hollow by back seal forming means 640. Filling device 601 discharges the contents in synchronization with sealing bars 651A, 651B sandwiching film 110 in top / bottom seal forming means 650, filling the space formed above the bottom seal of the bag-shaped container with the contents. Thereafter, when sealing bars 651A, 651B separate, the contents are conveyed downward over sealing bars 651A, 651B together with film 110, and then a top seal is formed, sealing the bag-shaped container filled with the contents.

[0023] In the bag making apparatus 600 as described above, the conveyed tape 3 is joined to the film 110 by the seal bars 612A, 612B to produce a film with tape. Furthermore, the film 110 with the joined tape 3 is processed into a bag-shaped container body by the back seal forming means 640 and the top / bottom seal forming means 650 to produce a bag-shaped container with tape.

[0024] FIG. 8 is a diagram showing an example of a tape-attached film that can be provided in the example of FIG. 7. In the example of the bag-making apparatus 600 described above, the film 110 can be wound up after the steps up to the tab forming means 620 are completed, and provided as the tape-attached film 210, which is an intermediate product. The tape-attached film 210 includes the film 110 and at least two or more tapes 3 attached to one side of the film 110, spaced apart from each other along the longitudinal direction of the rolled film 110. The long member may have tabs formed by slits 151. In order to form the container body by folding as described above, in the tape-attached film 210, the width L1 of the film 110 is greater than twice the length L2 of the tapes 3.

[0025] FIG. 9 illustrates a first example of a container to which a tape constituting a tape package according to an embodiment of the present invention is attached. In the illustrated example, the tape 3 is a zipper tape and includes a pair of bases 31A, 31B and a pair of engagement portions 32A, 32B protruding from each base. The surfaces of the bases 31A, 31B opposite the engagement portions 32A, 32B constitute the front and back surfaces of the tape 3. As already mentioned, the terms "front surface" and "back surface" merely distinguish between the two surfaces of the tape 3. Therefore, either the surface of the base 31A facing the male engagement portion 32A or the surface of the base 31B facing the female engagement portion 32B may be referred to as the "front surface." In this case, the tape 3 is attached to the bag-like container 100 by bonding the front and back surfaces to the first surface 110A and second surface 110B, respectively, of the film 110 constituting the container body. The zipper tape may include two or more pairs of engagement portions. Furthermore, the engaging portions are not limited to the male-female type engaging portions 32A, 32B in the illustrated example, but various known shapes of engaging portions of zipper tapes, such as hook shapes, can be adopted.

[0026] FIG. 10 shows a second example of a container to which a tape constituting a tape package according to an embodiment of the present invention is attached. In the illustrated example, tape 3 is a tear tape, and base 33 includes two portions 33A and 33B sandwiching a slit. A tear strip 34 is disposed in a recess formed in the portion of base 33 containing the slit. In this case, tape 3 is attached to bag-like container 100 by bonding one surface (front or back), specifically the surface of base 33 opposite the slit, and tear strip 34 to first surface 110A of film 110 constituting the container body. When first surface 110A is torn with tear strip 34, an opening can be formed in bag-like container 100 through the slit between two portions 33A and 33B of base 33. In this way, tape 3 may be bonded to the film of the container body only on either the front or back surface. Tape 3 may also include multiple portions with different resin compositions, such as the base and tear strip.

[0027] 9 and 10 are merely illustrative examples, and the present invention is not limited to these examples. The configuration of the tape package according to the embodiment of the present invention can be applied to various types of tape that are stored or transported in a packed container and are pulled out and joined to the film or the like of the container body when in use. For example, the configuration of the tape package according to the embodiment of the present invention can be applied to a tape that combines a zipper tape as shown in Fig. 9 with a tear strip as shown in Fig. 10, or a tape that has a pair of bases each formed with a thin portion to guide tearing when the bag-like container is opened.
