Abstract

A tape includes, in a cross-sectional shape: a first and a second portion which are configured to be at least partially in opposition. The first portion includes: thick portions provided in corresponding one of a first and a third region, out of the first, a second, and the third region in a width direction of the tape; a first and a second thin portion provided at respective both end portions, in the width direction, of the second region positioned between the first and the third region; and at least one intermediate portion provided between the first and the second thin portion. The second portion includes: thick portions provided in corresponding one of the first and the third region and extending beyond end portions, in the width direction, of the second region; and at least one third thin portion provided in the second region and opposed to the intermediate portion.

First claim

The invention claimed is:

1. A tape comprising, in a cross-sectional shape thereof:
a first portion; and
a second portion, the first portion and the second portion being configured to be at least partially opposed to each other, wherein
the first portion comprises
a first thick portion and a second thick portion each provided in corresponding one of a first region and a third region, out of the first region, a second region, and the third region in a width direction of the tape,
a first thin portion and a second thin portion provided at respective both end portions, in the width direction, of the second region, the second region being positioned between the first region and the third region, and
at least one intermediate portion provided between the first thin portion and the second thin portion,

the second portion comprises
a third thick portion and a fourth thick portion that are each provided in corresponding one of the first region and the third region and are extending beyond end portions, in the width direction, of the second region, and
at least one third thin portion that is provided in the second region and is opposed to the intermediate portion,

the first thin portion is directly opposed to only the third thick portion in a thickness direction of the tape, and
the second thin portion is directly opposed to only the fourth thick portion in the thickness direction.

2. The tape according to claim 1 , wherein the intermediate portion has a thickness corresponding to thicknesses of the first thick portion and the second thick portion.

3. The tape according to claim 1 , wherein
the first thin portion, the second thin portion, and the third thin portion each have a thickness in a range from 10 μm to 200 μm, and
the first thick portion, the second thick portion, the third thick portion and the fourth thick portion each have a thickness in a range from 200 μm to 700 μm.

4. The tape according to claim 1 , wherein the first region, the second region, and the third region cover the tape entirely.

5. The tape according to claim 1 , wherein the first portion and the second portion are coupled to each other at respective end portions, in the width direction, of the first portion and the second portion in the first region or the third region, the respective end portions being on a side opposite to the second region.

6. A container equipped with a tape, the container comprising:
a container body having a first surface and a second surface that are at least opposed to each other; and
the tape according to claim 1 in which at least a portion of the first portion is bonded to the first surface and at least a portion of the second portion is bonded to the second surface.

7. The container equipped with the tape according to claim 6 , wherein the first thick portion and the second thick portion and the intermediate portion are bonded to the first surface, and the third thick portion and the fourth thick portion are bonded to the second surface.

8. The container equipped with the tape according to claim 6 , wherein the container body has a bag shape.

9. The container equipped with the tape according to claim 6 , wherein
side seal portions where the first surface and the second surface are bonded to each other are provided at both ends of the container body, and
a cutout is provided at an end portion in a longitudinal direction of the tape in an overlapping manner on each of the side seal portions.

10. The container equipped with the tape according to claim 9 , wherein
the cutout is provided within the first portion comprising a taper portion or a bulging portion directed toward the first thin portion and the second thin portion, and
the cutout is provided within the second portion comprising a taper portion or a bulging portion directed toward the third thin portion.

11. The container equipped with the tape according to claim 10 , wherein
the cutout is provided within the first portion comprising a first bulging portion and a second bulging portion respectively directed toward the first thin portion and the second thin portion, and
the cutout is provided within the second portion comprising a taper portion directed toward the third thin portion.

12. The container equipped with the tape according to claim 11 , wherein the first bulging portion projects toward a center in the longitudinal direction of the tape at a great degree as compared with the second bulging portion.

13. The container equipped with the tape according to claim 10 , wherein
the cutout is provided within the first portion comprising a first taper portion and a second taper portion respectively directed toward the first thin portion and the second thin portion, and
the cutout is provided within the second portion comprising a taper portion directed toward the third thin portion.

14. The container equipped with the tape according to claim 10 , wherein a first position where the taper portion or the bulging portion couples to the first thin portion in the first portion and a second position where the taper portion or the bulging portion couples to the third thin portion in the second portion are different from each other in the longitudinal direction of the tape.

15. The container equipped with the tape according to claim 14 , wherein the second position is close to the end portion in the longitudinal direction of the tape as compared with the first position.

16. The container equipped with the tape according to claim 15 , wherein a distance between the first position and the second position is in a range from 2 mm to 50 mm.

17. The container equipped with the tape according to claim 9 , wherein
the cutout is provided within the first portion comprising a first taper portion directed toward the first thin portion, and at least one inclined side or a curved part to be directed to the first taper portion,
the cutout is provided within the second portion comprising a taper portion or a bulging portion directed toward the third thin portion, and,
in a case where the first portion and the second portion are overlapped with each other, the at least one inclined side or the curved part traverses the third thin portion.

18. A method of manufacturing the container equipped with the tape according to claim 9 , the method comprising:
forming the cutouts in the tape;
bonding the tape in which the cutouts are formed to the container body; and
forming the side seal portions each traversing the cutouts on the container body to which the tape is bonded.

19. A zipper tape comprising, in a cross-sectional shape thereof:
a first portion; and
a second portion, the first portion and the second portion being configured to be at least partially opposed to each other, wherein
the first portion and the second portion each comprise, in a cross-sectional shape thereof, a base strip and an engagement portion, the engagement portions projecting from the respective base strips and being engageable with each other,
the first portion comprises
a first thick portion provided in a first region, out of the first region, a second region, and a third region in a width direction of the zipper tape,
a second thick portion that is provided in the third region and is continuous with the base strip,
a first thin portion and a second thin portion provided at respective both end portions, in the width direction, of the second region, the second region being positioned between the first region and the third region,
