Abstract

(57) [Abstract] [Purpose] When folding and packing multiple sets of socks together, a large triangular void is left in the upper part of the packaging bag to wrinkle, or the bottom of the bag is ear-shaped on both left and right sides. We propose a packaging bag for socks that has a simple structure, is easy to manufacture, and has a good appearance after packaging. [Structure] The bottom of the bag body is folded back inward, and the left and right edges of the folded back portion are heat-sealed along the left and right edges of the bag body. It is characterized in that a tongue piece having a substantially triangular shape is continuously provided.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sock packaging bag used when a plurality of pairs of socks are collectively stored and sold.

[0002]

[Prior art]

 When socks, such as socks for school children, are sold in groups of 3 to 5 pairs, the packaging bag used to make socks is transparent and has a rectangular shape. Since it is folded back and stored, depending on the fabric, the total thickness is 5 to 8 cm, and when it is simply stored in a rectangular packaging bag, the bag expands due to the above thickness and the left and right sides of the bottom part Not only will both ends project in an ear shape, but the entire upper opening of the bag will be bent downward at one angle on one side to close it, so the edges folded back at the heel part of the sock will be diagonal to the folding direction. Therefore, a large void of a regular triangle remains in the upper one corner of the bag (see Fig. 4). When it is transported or displayed in such a packaging state, many wrinkles are gathered in the triangular void portion of the packaging bag, and the ear-like protruding portion at the bottom is also bent, resulting in a badly-looking packaging form. I will end up.

[0003]

[Problems to be solved by the device]

 The present invention solves the above-described conventional drawbacks of a packaging bag for collectively storing and packing a plurality of pairs of socks, and the triangular voids are left on the upper part of the packaging bag to cause wrinkles, and bottom left and right sides. We propose a packaging bag for assembled socks that does not have ears on both sides and has a simple structure, is easy to manufacture, and has a good appearance after packaging.

[0004]

[Means for Solving the Problems]

 That is, in the packaging bag of the present invention, the bag-shaped bottom portion is folded back inward to heat the left and right edges, and a substantially triangular tongue piece that is offset to the left and right sides is connected to the front and rear sides of the upper part of the opening. With this structure, the bottom has a width corresponding to the thickness of the entire socks set, and at the same time, the triangular void as described above does not occur when the upper opening is folded back and closed. It is a thing. Hereinafter, an embodiment of the bag for sock packaging of the present invention will be described with reference to the drawings.

【Example】

 1 and 2 are a front view and a vertical cross-sectional view of a flat bag before packing socks according to the present invention, in which 1 is a bag body made of a transparent resin film as in the conventional case, The bottom portion of the bag body 1 is folded back inward to form a folded portion 2, and both left and right end edges 2a of the folded portion 2 are heat-sealed along with both end edges of the body 1.

Reference numeral 3 denotes a substantially triangular tongue piece made of the same material as that of the main body 1, which is connected to one side of the bag body 1 on the front and rear sides of the upper opening end thereof. When the socks 4 to be packaged are folded back to the opposite side at the heel 4a after leaving a gap of about half the thickness l ₁ , the angle of the heel 4a after folding and the bag body 1 A long side 3a having substantially the same angle (θ ₁ ) with respect to the upper piece l _2, a short side 3b in a direction (θ ₂ ) perpendicular to the long side 3a, and a side edge of the bag body 1 which is continuous with the short piece 3b. The tongue piece 3 is constituted by the rising side 3c, and the size of the tongue piece 3 is appropriately determined depending on the size of the bag body 1 (therefore, the size and thickness of the whole pair of socks to be packed).

However, when packing a plurality of pairs of socks 4 (four pairs of shoes in FIG. 3) with this packaging bag, each pair of socks 4 is folded back at the heel portion 4a, and the folded back edge 4b is turned up. And insert it into the bag body 1 through the upper opening. At this time, the inclined folded back edge 4b of the sock 4 is directed to the side facing the short edge 3b of the tongue piece 3.

When a predetermined set of socks 4 is stored in this way, the bag body 1 swells greatly and the bottom folding part 2 expands to form a bottom surface having a width corresponding to the thickness of the whole sock 4, Form a box-shaped bottom. Further, since the bag main body 1 as a whole has a substantially box shape, the double length of the length l ₁ at the opening upper portion thereof becomes the thickness of the entire sock 4, and the lower end corner of the long side 3 a of the tongue piece 3 The portion matches the upper corner of the bag body 1 having a box shape.

Therefore, the whole tongue piece 3 protruding upward is folded back while closing the upper opening of the bag body 1 so that the long side 3a thereof coincides with the same side edge of the bag body 1 (see FIG. 3). . At this time, the upper corner portion of the bag body 1 on the rising portion 3c side of the tongue piece 3 is folded inward. As a result, the upper end surface of the bag body 1 exactly matches the inclined surface formed by the folded back edge 4b of the sock 4, and the short side 3b of the tongue 3 is perpendicular to the length direction of the bag body 1. Therefore, the short side 3b is fixed to the outer surface of the bag body 1 by the adhesive tape 5 (or the inner surface of the short side 3b is coated with an adhesive).

[0010]

[Effect of device]

 The packaging bag for a pair of socks of the present invention is constructed as described above, and even if the sock is folded in a packed state and becomes thick, the substantially triangular tongue piece 3 formed at the upper part of the opening is folded back and closed. , The upper surface of the packaging bag matches the inclined surface formed by folding the heel of the sock, so that there is no large triangular void in the upper part of the bag as in the conventional case, and the bottom also has the folded portion 2. The presence of the bottom forms a width corresponding to the total thickness of the folded socks, so that the bottom ends do not project like ears, and the shape of the folded socks can be roughly matched. Therefore, the appearance after packaging is extremely good, and the packaging bag itself does not have unsightly wrinkles unlike the conventional case.
