Description

  The present invention relates to a method of manufacturing a card case for storing a card such as a name tag, an employee ID card, and an IC card, and hanging the card from a user's neck.

  As is well known, at work and event venues, the entrance and exit persons display their own self, and in order to increase security, a card case containing a card such as a business card, employee ID card, IC card, etc. Be suspended. A card case is disclosed in Patent Document 1, for example. A neck strap is attached to the card case in order to suspend the card case from the user's neck.

  The card case is formed of a transparent and flexible plastic sheet portion, and is configured to allow the card to be taken in and out through the opening. The neck strap is attached to the card case via the connecting means, and is suspended from the neck of the entry / exit.

  For example, as disclosed in Patent Document 2, the card case is provided with a chuck seal (waterproof fastener 7) at an opening for inserting and removing the card in order to waterproof the card stored in the card case. Then, as in the card case manufacturing method disclosed in Patent Document 3 and the like, the card case is manufactured by stacking two sheet portions and welding the peripheral portion of the card case. This manufacturing method is excellent in productivity because there are few processing steps.

  A conventional card case includes a chuck seal in an opening formed between two sheet portions (first and second sheet portions). Therefore, even if the peripheral portions of the two stacked sheet portions are welded as in the conventional card case manufacturing method, there is no problem because the opening portion is not blocked.

  However, in this card case, there is a problem that water enters from the opening when the chuck seal is not completely closed. Therefore, it is conceivable to attach a third sheet portion for closing the opening of the card case. In this card case, when the card is stored, the opening can be blocked by the third sheet portion, and when the card is inserted or removed, the opening can be prevented from being blocked by the third sheet portion.

  However, when this card case is manufactured by a conventional manufacturing method, the three sheet portions including the third sheet portion are stacked, and the peripheral portion of the card case to be manufactured is welded. Therefore, since the third sheet portion is welded to other sheet portions including the left and right sides, the third sheet portion is welded in a state where the opening of the card case is closed. Therefore, in the conventional card case manufacturing method, there is a problem that the third sheet portion that can close or not close the opening of the card case cannot be welded by a method with excellent productivity.

Utility Model Registration No. 3091123 JP 2009-128517 A JP-A-9-266810, paragraphs 0019-0023, FIG.

  Therefore, the problem to be solved by the present invention is to provide a manufacturing method of a card case that can weld the third sheet portion that can close or not close the opening of the card case by a method that is excellent in productivity. is there.

  As shown in FIGS. 1 and 2, the first piece 5 and the other piece 6 of the chuck seal are supplied to the first continuous sheet 11 fed out from the first original fabric 110. One piece 5 and the other piece 6 of the chuck seal are conveyed in the conveying direction X in parallel with the first continuous sheet 11.

  By the second processing means 22 (FIG. 1) provided on the downstream side of the first original fabric 110, the one piece 5 of the chuck seal is welded to the end of the second sheet portion 2 of the first continuous sheet 11, and further The other piece 6 of the chuck seal is welded to the end of the third sheet portion 3 of the first continuous sheet 11 (FIGS. 2 and 3). Similar to the first processing means 21, the second processing means 21 includes known means such as a high-frequency welding device, a heat seal device, and an ultrasonic welding device.

  Thereafter, as shown in FIGS. 1, 2, and 3 (C), the first continuous sheet 11 is folded along the folds FL and FL by the folding means 25. The folding means 25 includes known means such as a folding knife and a folding roller. As a result, as shown in FIG. 3C, the second sheet portion 2 is disposed above the first sheet portion 1, and the third sheet portion 3 is disposed above the first and second sheet portions 1 and 2. As shown, the first, second, and third seal portions 1, 2, and 3 are overlapped. The third sheet portion 3 is disposed so as to close the opening 31 to be formed between the first and second sheet portions 1 and 2. The one piece 5 and the other piece 6 of the chuck seal face each other.

Thereafter, as shown in FIGS. 1, 2, 3 (C), and 4, the welding prevention sheet 4 is supplied to the stacked first, second, and third seal portions 1, 2, and 3. The welding prevention sheet 4 is made of a PET film, paper, or the like that can be fused and welded at a second temperature T ₂ (T ₂ > T ₁ ) higher than the first temperature T ₁ . The welding prevention sheet 4 is conveyed in the conveyance direction X in parallel with the first and second continuous sheets 11 and 12. As shown in FIGS. 3C and 4, the welding prevention sheet 4 is disposed below the third sheet portion 3 and above the first and second sheet portions 1 and 2.

Thereafter, the third processing means 23 (FIG. 1) causes the welding prevention sheet 4 to be formed along the peripheral portions of the pair of card cases 30 and 30 on both sides of the boundary line BL of the first and second continuous sheets 11 and 12. The arranged first, second, and third sheet portions 1, 2, and 3 are fused and welded to each other at a temperature t (T ₂ > t ≧ T ₁ ) that is equal to or higher than the first temperature T ₁ and lower than the second temperature T ₂ . Similar to the first processing means 21, the third processing means 23 includes known means such as a high-frequency welding device, a heat seal device, and an ultrasonic welding device.

  As shown in FIG. 4A, the welding prevention sheet 4 extends in the left-right direction W (conveying direction X) of the card case 30. The first and second seal portions 1 and 2 are welded to the lower side portion 301 of the card case 30, and the first and third seal portions 1 and 3 are welded to the upper side portion 302 of the card case 30. In the left and right side portions 303 and 304 of the card case 30, only the first and second seal portions 1 and 2 are welded, and the first and third seal portions 1 and 3 are not welded.

The welding prevention seal 4 is disposed over the left and right side portions 310 and 311 of the third seal portion 3 (FIG. 4A). Further, the welding prevention sheet 4 is not disposed on the upper side 312 of the third seal portion 3 (the upper side 302 of the card case 30). In the vertical direction Z, the welding prevention sheet 4 is disposed below the third sheet portion 3 and above the first and second sheet portions 1 and 2 (FIG. 4B). Furthermore, since the treatment at a first temperature above _{T 1} second temperature _{T 2} lower than the temperature _{t (T 2> t ≧ T} 1), the welding prevention sheet 4 (second temperature _{T 2} or higher melting point) is blown and deposited without the first, second and third sheet portions 1,2,3 (first temperature above _{T 1} is the melting point) only is blown, and welding. As a result, the third seal portion 3 is not welded to the first and second seal portions 1 and 2 at the left and right side portions 310 and 311 of the third seal portion 3 where the weld prevention sheet 4 is disposed. Only the upper side 312 (the upper side 302 of the card case 30) of the third seal part 3 where 4 is not disposed is welded to the first seal part 1.

  Therefore, when the welding prevention sheet 4 is removed from the first, second, and third sheet portions 1, 2, 3, the third sheet portion 3 is welded at the left and right side portions 303, 304 of the card case 30, as shown in FIG. Instead, since it is welded only at the upper side portion 302 of the card case 30, the opening portion 31 can be blocked or not blocked by the third sheet portion 3.

  As shown in FIG. 4A, the card case 30 is provided with three hole portions 32 for attaching neck strap connecting means (not shown) at the top thereof. Of course, the number of the holes 32 may be one or may not be.

  In the manufacturing method described above, the peripheral portion of the card case 30 can be obtained simply by disposing the welding prevention sheet 4 having a high melting point temperature at a predetermined position of the first, second, and third sheet portions 1, 2, and 3 stacked. If the welding prevention sheet 4 is removed from the first, second, and third sheet portions 1, 2, and 3 even if welding and cutting are performed along the upper and lower portions 302, the card case 30 is welded only. The opening 31 can be blocked or not blocked by the three sheet portions 3. Therefore, the 3rd sheet | seat part 3 can be welded by the method excellent in productivity.

  Furthermore, in the manufacturing method described above, the pair of card cases 30 and 30 can be fused to both sides of the boundary line BL of the first and second continuous sheets 11 and 12, so that a large number of card cases 30 can be efficiently manufactured in a short time. Can be manufactured well.

  Further, in the above manufacturing method, the one piece 5 and the other piece 6 of the chuck seal are welded to the second and third seal portions 2 and 3, so that the opening 31 of the card case 30 can be more reliably waterproofed by the chuck seal. .
