<First embodiment>
An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a front view of the composite container of the first embodiment. The composite container 1 is formed by inserting a bag 10 with a chuck through a cylindrical sleeve 20, and the width of the sleeve 20 is formed to be 60 to 135 mm so as to fit into a palm of one hand of a user.

  The bag 10 with a zipper has a bag main body 11 formed of a soft resin film, and a pair of zipper members 12 arranged opposite to each other and thermally bonded to the inner surface of the bag main body 11. In the bag 10 with a zipper, confectionery such as gum and gummy, powder such as sprinkle and granular seasoning, and powder and granular contents such as tablets and granular health food are hermetically stored.

  The bag body 11 is formed by thermally bonding the four sides around it with a thermal bonding portion 10b. One end of both sides and the lower end of the bag body 11 may be bent, and three sides may be thermally bonded by the thermal bonding portion 10b. A pair of notches 31 for opening the thermal bonding portion 10b at the upper end are provided on both side edges of the upper end of the bag 10 with the zipper.

  FIG. 2 is a perspective view of the composite container 1 after opening, and FIG. The notch 31 is disposed above the chuck member 12, and when eating or the like, the notch 31 is cut off by cutting in the lateral direction to form the opening 10 a. Then, the opening 10a is opened and closed by the engagement and disengagement of the chuck member 12 arranged to extend in the left-right direction along the opening 10a.

  In addition, the bag 10 with a chuck which has an opening 10a and does not need to be cut off by a user may be used without bonding the upper end of the bag body 11 by heat. Further, the notch 31 may be arranged on an extension of the upper side of the sleeve 20. Thereby, the bag 10 with a zipper can be easily cut straight and open along the upper side of the sleeve 20.

The sleeve 20 is provided with a plurality of fold lines 21 and 23 that are repeatedly bent and folded back as described in detail below. For this reason, the sleeve 20 is formed of cardboard having a basis weight of 260 to 450 g / m ² so that the sleeve 20 is not bent at a portion other than the folding lines 21 and 23. The sleeve 20 is shifted to the left and right with respect to the folding line 21 on the chuck member 12 and below the chuck member 12, and is bonded to the bag with chuck 10 by the bonding portion 30.

  The upper end of the sleeve 20 is disposed between the upper end of the bag 10 with the chuck and the chuck member 12. Note that the upper end of the sleeve 20 may be arranged below the chuck member 12. Further, the lower end of the sleeve 20 is disposed below the lower end of the bag 10 with the chuck.

  Notches 28, which will be described in detail later, are provided at upper ends of both sides of the sleeve 20, and upper ends of both ends of the bag 10 with the chuck are exposed through the notches 28.

  FIG. 4 shows a vertical sectional view of the chuck member 12. The pair of chuck members 12 are formed by opposing male parts 13 and female parts 14. The male part 13 has a support part 13a, an engagement part 13b, and a base part 13d. The base portion 13 d is formed in a band shape extending left and right, and is fixed to the inner surface of the bag body 11. The support portion 13a protrudes from the base portion 13d to the inner surface of the bag body 11. The engagement portion 13b is provided at a tip of the support portion 13a. The engagement portion 13b has an engagement surface 13c projecting vertically from the support portion 13a, and the engagement surface 13c is formed facing the bag body 11.

  The female part 14 has a support part 14a, a concave part 14b, a claw part 14c, and a base part 14d. The base portion 14 d is formed in a belt shape extending left and right, and is fixed to the inner surface of the bag body 11. The support portion 14a is protruded from the base portion 14d to the inner surface of the bag body 11. The concave portion 14b is provided at the tip of the support portion 14a, and the engaging portion 13b is fitted. The claw portions 14c are provided at the tips of the concave portions 14b, and protrude from the upper and lower ends of the concave portions 14b in directions approaching each other. The claw portion 14c engages with the engagement surface 13c of the male portion 13.

  When the engaging portion 13b is fitted into the concave portion 14b and the claw portion 14c is engaged with the engaging surface 13c, the bag 10 with the chuck is sealed by the chuck member 12. Further, when the male portion 13 and the female portion 14 are weighted in a direction in which the male portion 13 and the female portion 14 are separated, the claw portion 14c slides on the engagement surface 13c, and the engagement between the claw portion 14c and the engagement surface 13c is released. Thereby, the opening 10a of the bag 10 with a zipper is opened. The chuck member 12 can be formed to have a desired fitting strength by the inclination angle of the engaging surface 13c and the claw portion 14c and the length of the engaging surface 13c.

  FIG. 5 shows a development view of the sleeve 20. The sleeve 20 has a front portion 20a and a back portion 20b which are adjacent to each other at a fold line 23. The back surface portion 20b is divided on both sides of the front surface portion 20a, and is bonded at one end thereof with an adhesive 29 applied on the adjacent margin 20c via a fold line 21. As a result, the sleeve 20 is formed in a tubular shape with the folding line 23 as a crease at both ends.

  A fold line 21 (central fold line) that extends in the vertical direction and is mountain-folded outward is provided at the center in the left-right direction of the front part 20a and the back part 20b. The fold line 21 is formed by a lead rule or perforation. A part of the sleeve 20 made of cardboard passes through the cut line of the fold line 21. For this reason, if an adhesive is applied on the fold line 21 to form the adhesive portion 30, there is a risk that the adhesive leaks from a cut at the time of bonding. Accordingly, the bonding portion 30 for bonding the front surface portion 20a and the bag 10 with the chuck is displaced to the left near the folding line 21 when viewed from the front. Further, an adhesive portion 30 for adhering the back portion 20b and the bag 10 with a chuck is displaced to the right near the fold line 21 when viewed from the front.

  In the present embodiment, the bonding portion 30 for bonding the front surface portion 20a and the bag 10 with the chuck is provided at a position 3 mm to 6 mm away from the folding line 21. The bonding portion 30 for bonding the back surface portion 20b and the bag 10 with the chuck is provided at a position 4 mm to 7.5 mm away from the folding line 21 in order to surely separate the bonding portion 30 from the adhesive 29 on the glue allowance 20c. Each of the bonding portions 30 is formed with a length of 5 mm or more downward from above the chuck member 12. It is sufficient that at least a part of the bonding portion 30 is disposed on the chuck member 12.

  A pair of cutouts 28 are provided at both ends of the front part 20a and the back part 20b at the upper end. The notch 28 has an open upper end, and has a lower side 28a and a pair of side sides 28b. The lower side 28a extends in the left-right direction from the upper end of the fold line 23, and is formed so as to be inclined upward as the distance from the fold line 23 increases.

  Further, the lower side 28a is disposed below the chuck member 12, and the lower end of the lower side 28a is disposed at a position separated from the bases 13d and 14d by 20 mm or more.

  The side edges 28b are disposed at the left and right ends of the front surface 20a of the sleeve 20 and at the left and right ends of the rear surface 20b. The side sides 28b extend upward from the upper ends of the lower sides 28a, respectively, and are formed substantially parallel to the fold lines 23. A chamfer 28c is formed at the upper end of the side 28b.

  A pair of inclined portions 34 are provided at lower ends of both sides of the front portion 20a and the back portion 20b. The inclined portion 34 is cut out in a V-shape, and is inclined downward as the distance from the folding line 23 increases.

  6 and 7 are a perspective view and a top cross-sectional view showing a state when the contents are filled in the composite container 1. FIG. At the time of filling the contents, the fitting of the chuck member 12 is released, and the left and right ends of the bag body 11 exposed from the notch 28 are gripped by the pair of grippers 41 provided on the holding device 40, respectively. . At this time, since the lower side 28a of the notch portion 28 is disposed below the chuck member 12, the gripper 41 can easily grip the lower portion of the chuck member 12.

  The left and right grippers 41 holding the bag body 11 move in directions approaching each other as shown by an arrow D. At this time, the side 28b of the notch 28 forming the side end surface of the front part 20a and the back part 20b comes into contact with the tip part 41a of the gripper 41 and is pressed. Further, the lower side 28a of the notch 28 is disposed below the chuck member 12, and the contact position between the side 28b of the notch 28 and the tip 41a of the gripper 41 is lower than the chuck member 12. Be placed.

  Accordingly, the side end surfaces of the front surface portion 20a and the back surface portion 20b are pressed from below the chuck member 12 by the distal end portion 41a of the gripper 41. Since the sleeve 20 made of cardboard has high rigidity, the front portion 20a and the back portion 20b are easily deformed outwardly and the bag 10 with the zipper is greatly opened.

  Therefore, without gripping the outer surface of the sleeve 20 with the gripper 41, the side 28b of the notch 28 can be pressed by the tip 41a of the gripper 41 to open the bag 10 with the chuck. This can prevent the outer surface of the sleeve 20 from being damaged when the contents are filled.

  At this time, since the side 28b of the notch 28 is formed substantially parallel to the folding line 23, the tip 41a contacts the side 28b in a wide range. For this reason, bag 10 with a zipper can be opened easily.

  The front part 20a and the back part 20b have a fold line 21 passing through the center in the left-right direction. When the both ends of the sleeve 20 are pressed, the fold line 21 is mountain-folded outward. Therefore, the pressing force of the gripper 41 can be further reduced to easily open the bag 10 with the chuck. Accordingly, the pressing force applied to the contact position between the side end surfaces of the front surface portion 20a and the back surface portion 20b and the front end portion 41a can be reduced, and the side end surfaces can be further prevented from being damaged.

  A nozzle is inserted into the opened bag 10 with a chuck from above, and the contents are filled. The chuck member 12 of the bag 10 with the contents filled therein is closed, and the upper end portion is thermally welded. Thereby, the sealed composite container 1 containing the contents is obtained.

  In the composite container 1 having the above-described configuration, the notch 31 is cut off in a lateral direction at the time of eating or the like, and the upper end portion of the bag 10 with a chuck is cut.

  The bag 10 with the zipper holds the lower part of the composite container 1 sealed by the zipper member 12 with the palm of the user, and fingers (for example, thumb and forefinger) are arranged on both side ends of the sleeve 20. When the both ends of the sleeve 20 are pressed so that the fingers at both ends approach each other, the sleeve 20 formed of cardboard is mountain-folded at the fold line 21 because of its high rigidity.

  At this time, the bonding portion 30 for bonding the front surface portion 20a and the bag 10 with the chuck is displaced to one side in the left-right direction near the folding line 21. Further, an adhesive portion 30 for adhering the back surface portion 20b and the bag 10 with a chuck is arranged near the folding line 21 so as to be shifted to the other side in the left-right direction. For this reason, a force acts in a direction in which the front and rear surfaces of the chuck member 12 shift right and left, and the left and right fold lines 23 approach, and the center fold line 21 is mountain-folded. Further, since the bonding portion 30 is disposed on the chuck member 12, the fitting of the chuck member 12 is easily released from below, and the opening 10a of the bag with chuck 10 can be opened with one hand.

  In addition, since the notch portions 28 are arranged on both upper ends of the sleeve 20, the user is guided to hold the lower portion of the sleeve 20 while avoiding the notch portions 28. The front part 20a and the back part 20b of the lower part of the sleeve 20 can be more easily mountain-folded along the center fold line 21 than the upper part of the sleeve 20 in which the chuck member 12 is engaged. Therefore, the front portion 20a and the rear portion 20b can be mountain-folded with a smaller force, and the engagement of the chuck member 12 can be more easily released.

  According to the present embodiment, the front portion 20 a and the back portion 20 b of the sleeve 20 have the cutout portions 28 that are cut out from both side ends to expose the bag body 11, and the lower side 28 a of the cutout portion 28 is smaller than the chuck member 12. It is arranged below. Thus, the gripper 41 can open the bag 10 with the chuck by pressing the side 28a of the notch 28 with the tip 41a of the gripper 41 without holding the outer surface of the sleeve 20 with the gripper 41. Therefore, the outer surface of the sleeve 20 can be prevented from being damaged when the contents are filled, and the aesthetic feeling of the composite container 1 can be improved.

  The lower side 28a of the notch 28 is disposed below the lower ends of the bases 13d and 14d, and the lower end of the lower side 28a is disposed at a position 20 mm or more away from the bases 13d and 14d. Thereby, the grip 41 can be reliably pinched below the chuck member 12 of the bag main body 11, and the bag main body 11 can be more reliably opened.

  Since the side 28b of the notch 28 is formed substantially parallel to the folding line 23, the tip 41a of the gripper 41 contacts the side 28b in a wide range. For this reason, bag 10 with a zipper can be opened easily.

<Second embodiment>
Next, FIG. 8 shows a front view of the composite container 1 of the second embodiment. For convenience of explanation, the same parts as those in the first embodiment shown in FIGS. 1 to 7 are denoted by the same reference numerals. In the present embodiment, the notch 28 has an upper side 28 d extending from above the crease 23 as compared with the first embodiment. Other parts are the same as in the first embodiment.

  The notch 28 is not open at the upper end, and has an upper side 28d, a lower side 28a, and a pair of side sides 28b. As a result, the front surface 20a and the back surface 20b of the sleeve 20 are connected to each other above the notch 28 via the folding lines 23 at both ends. The upper side 28d extends in the left-right direction from the fold line 23, is connected to the upper end of the side side 28b, and is formed so as to be inclined downward as the distance from the fold line 23 increases.

  The notch 28 has an upper side 28c extending from the fold line 23, and the front part 20a and the back part 20b are continuously provided above the notch 28, so that the strength of the upper ends of the front part 20a and the back part 20b is increased. Can be improved. Therefore, it is possible to prevent the beauty of the composite container 1 from being degraded due to the upper ends of the both sides of the front portion 20a and the back portion 20b being curved outward.

  ADVANTAGE OF THE INVENTION According to this invention, it can utilize for the composite container which has the bag with a zipper which accommodates the content of the powder and granular materials, such as foodstuffs.
