A bag that folds down to card size.

Abstract

The present invention provides a bag that can be easily folded from its unfolded state and can be stably stored in a small, card-sized form. [Solution] The bag comprises a bag body capable of storing luggage, a pleated structure formed in the bag body, and a retaining band that holds the bag body in a stored state. The pleated structure includes vertical mountain fold lines 4a and vertical valley fold lines 4b for folding the bag body vertically, and horizontal mountain fold lines 4c and horizontal valley fold lines 4d for sequentially folding the rod-shaped bag body in the longitudinal direction. The bag body becomes rod-shaped when folded along the vertical mountain fold lines 4a and vertical valley fold lines 4b, and then becomes a card-sized storage state when sequentially folded in the longitudinal direction along the horizontal mountain fold lines 4c and horizontal valley fold lines 4d.

Description

[Technical Field]

[0001] The present invention relates to a bag, and particularly to a foldable bag that can be folded from an expanded state into a small stored state. [Background Art]

[0002] Conventionally, as bags used for shopping or going out, foldable bags that can be smallly folded and stored when not in use have been known.

[0003] Many such foldable bags have a configuration in which a bag-shaped bag body is folded to reduce size for improving portability. Problem to be Solved by the Invention

[0004] However, conventional foldable bags tend to have unstable shape after folding, and may be bulky when carried or cause the stored state to collapse.

[0005] In addition, in order to smallly fold the bag body, a user needs to fold it multiple times while arranging creases, and it may be difficult to store the bag into a fixed shape in a short time.

[0006] The present invention has been made in view of such circumstances, and an object thereof is to provide a bag that can be easily folded from an expanded state and can be stably held in a small stored state about the size of a card. Means for Solving the Problem

[0007] In order to solve the above problem, the bag according to the present invention comprises: a bag body capable of storing luggage; and a pleated structure formed on the bag body.

[0008] The pleated structure includes vertical mountain fold lines and vertical valley fold lines for folding the bag body in the vertical direction, and horizontal mountain fold lines and horizontal valley fold lines for sequentially folding the bar-shaped bag body in the longitudinal direction.

[0009] The bag body is folded along the vertical mountain fold lines and vertical valley fold lines to form a rod shape, and the rod-shaped bag body is then sequentially folded along the horizontal mountain fold lines and horizontal valley fold lines in the longitudinal direction to form a storage state approximately the size of a card. Effect of the design

[0010] According to this invention, the pleated structure formed in the bag body allows the bag body to be folded vertically into a rod shape.

[0011] Furthermore, by sequentially folding the rod-shaped bag body along its length, the bag can be reduced to a small, card-sized storage configuration.

[0012] Furthermore, because it can be folded along the pleat structure, users can easily fold the bag into a consistent shape, ensuring a stable storage state. [Brief explanation of the drawing]

[0014] The embodiments of this invention will be described below with reference to the drawings.

[0015] As shown in Figure 1, the bag according to this embodiment comprises a bag body 1 capable of storing luggage and a handle 2 provided on the top of the bag body 1. An opening 3 for putting in and taking out luggage is formed in the top of the bag body 1.

[0016] The bag body 1 has a pleat structure 4 formed therein as a fold line structure for folding the bag body 1. The pleat structure 4 includes vertical and horizontal fold lines and guides the folding of the bag body 1 from the unfolded state to the card-size storage state 8.

[0017] As shown in Figure 2, the pleat structure 4 is formed by the intersection of multiple vertical fold lines and multiple horizontal fold lines formed on the bag body 1.

[0018] The multiple vertical fold lines consist of alternating vertical mountain fold lines 4a and vertical valley fold lines 4b, and are intended to reduce the width of the bag body 1 to a rod-shaped folded state 6.

[0019] Multiple horizontal fold lines consist of alternating horizontal mountain fold lines 4c and horizontal valley fold lines 4d, which, combined with vertical fold lines, form a pleated structure 4. After the bag body 1 is folded into a rod-like shape 6, it is sequentially folded along these horizontal fold lines in the longitudinal direction.

[0020] As shown in Figure 3, the bag body 1 is folded along the vertical mountain fold line 4a and the vertical valley fold line 4b, which reduces its width and results in a long, narrow, rod-shaped folded state 6.

[0021] As shown in Figure 4, the bag body 1, which is in a rod-shaped folded state 6, is sequentially folded along the horizontal mountain fold line 4c and the horizontal valley fold line 4d at the longitudinal folding section 7.

[0022] In this way, the bag body 1 is first folded into a rod shape along the vertical fold lines, and then the rod-shaped bag body 1 is folded back in the longitudinal direction to transition into a compact storage state.

[0023] As shown in FIG. 5 and FIG. 6, the bag body 1 sequentially folded in the longitudinal direction assumes a card-size storage state 8. In the card-size storage state 8, the bag body 1 is folded into a small substantially rectangular shape.

[0024] As shown in FIG. 7, the card-size storage state 8 is held by a holding band 9. The holding band 9 is, for example, an elastic band wound around the outer circumference of the bag body 1.

[0025] Further, a plate-shaped holding portion 10 that maintains the outer shape of the card-size storage state 8 may be provided. This allows the bag body 1 to be stably held in the card-size storage state 8.

[0026] It should be noted that the shape, size and material of the bag body 1, the arrangement of the pleated structure 4, the number of longitudinal fold lines and transverse fold lines, and the configurations of the holding band 9 and the plate-shaped holding portion 10 are not limited to the above embodiment.

[0027] For example, the bag body 1 can be configured as a shopping bag, a portable bag, a storage bag, or any of various other bags. Further, the member for holding the card-size storage state 8 is not limited to the holding band 9, and may be configured by an elastic band, a hook-and-loop fastener, a clasp, a flap, or other members.
