Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shopping bag made of synthetic resin.

[0002]

2. Description of the Related Art Shopping bags made of synthetic resin are widely used to facilitate the carrying of products purchased in supermarkets, department stores and the like. As such a shopping bag, as shown in FIG. 5, many of the front and rear sheets 52a and 52b are welded at the left and right ends thereof and formed into a bag shape having an opening 52c at the upper end. A hole 56 is formed in the upper portion of each of the sheets 52a and 52b so that a hand can be inserted therein.
The bag 50 can be carried by gripping an upper portion of the hole 52b above the hole 56 as a handle 53a.

[0003]

However, in the case of carrying the shopping bag as shown in the figure, the weight of the items put in the bag is the weight of the holes 56 in the sheets 52a and 52b.
Since it only acts on the left and right portions of the opening in the vertical direction, the left and right portions of the opening 52c are easy to open, and there is a problem that what is inside can be easily seen from the outside. In addition, since the thin portion of the lower end of the handle 53a (upper side of the hole 56) digs into the palm of the hand, there is a problem that the user feels uncomfortable.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a shopping bag whose opening is closed when held and which has a good feel.

[0005]

In order to achieve the above-mentioned object, according to the present invention, a front sheet and a body portion formed into a bag shape from a front sheet and a rear sheet which are connected to each other at a peripheral portion excluding an upper opening, and a front sheet. And a strip-shaped portion formed by folding back the peripheral portion of the opening in the rear sheet in a strip shape and having a joint portion with the main body portion in the vicinity of the left and right ends, and the left and right portions on the folding line between the main body portion and the strip-shaped portion. A shopping bag is constructed by making a left-right cut between the joints.

[0006]

In such a shopping bag, the non-joint portion (the portion sandwiched between the left and right joint portions) of the belt-shaped portion with the main body portion serves as a handle, and the handle is put under the handle through the cut to grasp the handle. This makes it possible to carry the shopping bag. At this time, the vicinity of the left and right ends of the upper portion of the main body is pulled toward the center in the left-right direction by the tensile force of the strip-shaped portion. For this reason, the upper end opening naturally closes, making it difficult for the contents inside to be seen from the outside.

Further, when the handle is gripped, a wide band-shaped area hits the palm of the hand, so that the handle does not dig into the hand as in the conventional case, and the feel of the handle is improved.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a shopping bag 1 according to the present invention. This shopping bag 1
Is formed in a bag shape by folding a strip-shaped synthetic resin sheet (opaque sheet) in two in the center in the longitudinal direction and overlapping and welding the left and right end portions of the front sheet 2a and the rear sheet 2b leaving the upper end opening 2c. The main body 2 and, as shown in detail in FIG. 2, the front sheet 2a and the rear sheet 2b each have a strip-shaped portion 3 formed by folding the periphery of the opening 2c outward in a strip shape. The left and right ends of the strip 3 are
When the front sheet 2a and the rear sheet 2b are welded, they are welded together. Further, as shown in detail in FIG. 3, portions near the left and right ends of the front and rear belt-shaped portions 3 are linearly welded to the main body portion 2 (front sheet 2a or rear sheet 2b). Hereinafter, this line is referred to as a welding line (bonding line) 4. These two
The welding line 4 of the book is arranged in a V shape so that the upper side of the band-shaped portion 3 approaches the center in the left-right direction. In addition, each welding line 4
The inclination angle θ with respect to the left-right direction is approximately 45 degrees.

Further, as can be seen from FIG. 1, a cut line 6 extending in the left-right direction is formed in a portion sandwiched between the upper ends of both welding lines 4 in the folding line 5 of the band-shaped portion 3 and the main body portion 2. For this reason, a portion (hereinafter, this portion is referred to as a handle) 3a sandwiched between the two welding lines 4 in the strip-shaped portion 3 is formed in the main body portion 2.
Can be pulled away from and pulled up.

When carrying the shopping bag 1 constructed in this way, as shown in FIG. 4, the handle 3a is pulled up above the main body 2 and then grasped by hand.
Due to this pulling force (conversely, the weight of the object put in the body portion 2), the left and right ends of the upper portion of the body portion 2 are pulled toward the center in the left-right direction as indicated by an arrow A in the figure. To be As a result, the opening 2a is also in a substantially closed state, and the substance contained in the main body 2 becomes almost invisible from the outside.

As can be seen from FIG. 3, the lower portion of the handle 3a in the state of being located along the main body 2 is
Longer than the upper part. For this reason, when the handle 3a is pulled upward, the portion near the upper end thereof spreads out substantially horizontally. Therefore, the handle 3a can be gripped by applying a large area near the upper end (a belt-shaped portion) to the palm.
Can be prevented from biting into the hand. Therefore, the feel of gripping the handle 3a is good.

In the above embodiment, the case where the strip-shaped portion is folded back to the outside of the main body has been described, but in the shopping bag of the present invention, the strip-shaped portion may be folded back inside the main body. . Further, in the above embodiment,
The case of making a shopping bag from a belt-shaped synthetic resin sheet has been described, but the shopping bag of the present invention may be manufactured by welding the bottom of a tubular synthetic resin tube and folding the periphery of the upper opening into a belt shape.

[0013]

As described above, in the shopping bag of the present invention, when the non-joint portion of the strip-shaped portion with the main body portion (the portion sandwiched between the left and right joint portions) is held as a handle, the upper portion of the main body portion is provided. The vicinity of the left and right ends is pulled toward the center in the left-right direction. For this reason, the upper end opening is naturally closed, and the contents inside cannot be seen from the outside.

Further, when the non-joint portion of the strip portion (the portion between the left and right joint portions) is pulled upward, this becomes a handle, and when the handle is gripped, a wide strip-shaped area can be applied to the palm. . Therefore, unlike the conventional case, the handle does not bite into the hand, and the feeling when held can be made extremely good.
