Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a flat-folded disposable dust-collecting paper bag for an electric vacuum cleaner.

[Conventional technology]

Conventionally, as this type of dust-collecting paper bag, for example, outer fold lines provided on both left and right sides of an upper surface portion having an intake port and outer fold lines provided on both left and right sides of a bottom surface portion facing the upper surface portion. And a cylindrical portion having left and right gussets constituted by both left and right inner fold lines provided on the left and right side surfaces connecting the upper surface portion and the bottom surface portion, and the inner surfaces of the front and rear end portions of the upper surface portion. The center point on the inside and the center points on the inner surfaces of the front and rear ends of the bottom surface, and the left and right end points on the inner surface of the front and rear ends of the top surface and the front and rear ends above the inner fold line of the gusset. The inner surface of the gusset, and the left and right end portions of the inner surface of the front and rear end portions of the bottom surface and the inner surface portions of the front and rear end portions of the lower part of the gusset above the inner fold line of the gusset. The outer surface of the front and rear ends of the part A dust collecting paper bag for an electric vacuum cleaner is known from Japanese Utility Model Publication No. 61-31744, which is characterized in that the gusset is laminated with the outer surface portions at the front and rear end portions below the inner fold line in a state of being overlapped with each other. Has become.

[Problems to be solved by the invention]

However, in this structure, the upper half and the lower half of each gusset portion are not attached to the front side and the rear side, so that when the gusset is expanded, the inner surface of the front and rear end portions of the upper surface portion At the central part and the central part on the inner surface of the front and rear end parts of the bottom part, and the sealing part, and on the left and right end parts on the inner surface of the front and rear end parts of the upper part and above the inner fold line of the gusset. Adhesion and sealing of inner surface parts on both front and rear ends, and left and right end parts on the inner surface of front and rear end parts of the bottom part and inner surface parts on both front and rear parts below the inner fold line of the gusset There is a problem in that the adhesion at the intersection with the sealed portion is easily peeled off by the internal pressure and an open hole is easily generated at the intersection.

[Operation and effect of device]

In the present invention, as described above, the central portion (10) on the inner surface of the front and rear ends of the upper surface portion (2) and the central portion (11) on the inner surface of the front and rear end portions of the bottom surface portion (4) are The left and right ends (12) and (12) 'on the inner surface of the front and rear ends of (2) and the front and rear ends of the gussets (8) and (8)' above the inner fold lines (7) and (7) ' The inner surface parts (13) (13) 'of the bottom part (4) and the left and right end parts (14) (14)' on the inner surface of the front and rear end parts of the bottom part (4) and the gusset (8)
The inner fold lines (7) and (7) 'of the (8)' are attached to the inner surface portions (15) and (15) 'of the front and rear end portions below the inner fold line (7) and (7)', and especially the gusset (8) (8 ) ′ Inside fold line (7) (7) ′
Outer surface parts (16) (16) ′ at both front and rear ends in the upper part
And the outer surface portions (11) (11) 'of the front and rear end portions below the inner fold line (7) (7)' of the same gusset (8) (8) ', respectively, in a state of being laminated. As a result of this, when the gusset is expanded, by means of this, a sticking and sealing part between the central part on the inner surface of the front and rear end parts of the upper surface part and the central part on the inner surface of the front and rear end parts of the bottom part, The left and right end portions on the inner surface of the front and rear end portions of the upper surface portion and the sticking and sealing portions of the inner surface portions of the front and rear end portions on the upper side of the inner fold line of the gusset,
Adhesion between the left and right end points on the inner surface of the front and rear ends of the bottom surface and the inner surface points of the front and rear ends on the lower side of the inner fold line of the gusset. Therefore, it is possible to sufficiently solve the problem in the above-mentioned known device that an open hole is easily generated at the same crossing point.
