Description

[Technical Field]

[0001] This invention relates to a waste paper storage bag made of a synthetic resin sheet that can be used to stack and store waste paper such as newspapers and magazines. [Background technology]

[0002] Conventionally, waste paper collection bags that store stacks of waste paper, such as multiple newspapers or magazines, have been known (see Patent Document 1). Conventional waste paper collection bags are configured so that the waste paper can be tied together with a string when it is stacked and collected in the bag, in order to make it easier to collect multiple pieces of waste paper or to make it easier to carry. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-70315 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the case of conventional configurations in which the bag is fastened with a string or the like, a separate string is required. Also, while it is common to store waste paper such as newspapers in a bag with a handle made of a synthetic resin sheet, in this case, the top opening is left fully open, which creates the problem that when it rains, the water is absorbed by the waste paper inside. Furthermore, while it is possible to partially close the top opening by using the handle to tie the top, this does not function as a handle, making the bag difficult to carry.

[0005] The present invention was made in consideration of the above circumstances, and its purpose is to provide a waste paper storage bag whose top opening can be closed without using a handle for binding. [Means for solving the problem]

[0006] One embodiment of the waste paper bag according to the present invention is made of a synthetic resin sheet and is designed to accommodate stacks of waste paper such as newspapers and magazines. The waste paper bag includes a bag body that has a bottom when unfolded and an open top, a covering piece extending upward from the upper ends of a first pair of opposing side surfaces on the outer periphery of the bag body to cover the top of a waste paper stack placed inside the bag body, an annular handle extending upward from the upper ends of a second pair of opposing side surfaces on the outer periphery of the bag body, and a binding piece extending upward from the lower ends of the annular portions of each of the handles to bind the waste paper stacks together on their top sides.

[0007] With this configuration, when waste paper such as newspapers and magazines is stacked inside the bag, the pair of covering pieces can be folded inward to cover the top of the waste paper bundle, and the top surface can be covered by the pair of covering pieces. Also, by pulling the other pair of binding pieces inward and binding the waste paper bundle on the top surface, the top opening on the other side of the waste paper bundle can be closed while the state in which it is covered by the covering pieces can be securely maintained.

[0008] Furthermore, in the waste paper storage bag, the bag body has a gusset portion folded inward from each of both widthwise ends when the sheet is formed into a cylindrical shape, and the lower and upper ends are sealed when the bag body is flattened to sandwich the gusset portion in the thickness direction, the opening is where the sealed portion in the center of the upper end of the bag body has been cut out, the bottom is the sealed lower end, and a notch of a predetermined length is formed extending downward from both widthwise ends of the center of the upper end so as to pass through a predetermined position spaced widthwise outward from the inner end on the central side of the gusset portion, the portion widthwise outer than the notch is the handle, and the portion of the gusset portion from the notch to the inner end is the binding piece. [Effects of the Invention]

[0009] According to this invention, it is possible to realize a waste paper storage bag whose top opening can be closed without using a handle for binding. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0011] The following describes an embodiment of the present invention with reference to the accompanying drawings. Note that the embodiment described below is merely an example of the present invention, and the embodiment of the present invention can be modified as needed without departing from the spirit and scope of the present invention.

[0012] The storage bag X according to the embodiment of the present invention (one example of a waste paper storage bag according to the present invention) is a waste paper storage bag configured to be able to store stacks of waste paper such as newspapers and magazines.

[0013] As shown in FIGS. 1 and 2, the storage bag X is made of a synthetic resin sheet, and includes a bag body 10, a covering piece 20, a handle 30, and a binding piece 40.

[0014] In this embodiment, the storage bag X is made of polyethylene, which is inexpensive, versatile, and highly recyclable. Specifically, HDPE (high density polyethylene), LDPE (low density polyethylene), or a mixture of these materials is used. Of course, the material is not limited to polyethylene, and the storage bag X may be made of a thin sheet made of a synthetic resin other than polyethylene, such as polypropylene or polyester.

[0015] The bag body 10 has a bottom 11 on the underside when the storage bag X is in an expanded state (see, for example, FIG. 4) so ​​that it can store waste paper. The outer peripheral surface of the bag body 10 has four side surfaces when in an expanded state, specifically including a pair of opposing side surfaces 12, 12 (an example of the first pair of side surfaces of the present invention) and a pair of opposing side surfaces 13, 13 (see FIG. 4).

[0016] The covering pieces 20 extend upward from the center of the upper ends of the pair of side surfaces 12, 12 that face each other on the outer circumferential surface of the bag body 10.

[0017] The pair of covering pieces 20 are formed to a size that allows them to cover the top surface of the waste paper bundle when the waste paper bundle, consisting of multiple stacked pieces of waste paper, is contained in the bag body 10 (for example, the state shown in Figure 5(A)). For example, the covering pieces 20 are formed to be roughly rectangular. The shape of the covering pieces 20 may be, for example, a square, a rectangle with the long side extending in the width direction (left and right direction in Figure 1), or a rectangle with the long side extending in the up and down direction. As will be described later, it is preferable that the covering pieces 20 are formed to a length that allows the tip ends 21 of the pair of covering pieces 20 to overlap each other (see Figure 5(A)) when folded inward.

[0018] When the bag body 10 is unfolded, the handle 30 extends upward from the upper end of the other opposing side surfaces 13, 13. The handle 30 is formed in a ring shape for easy carrying (see FIG. 4).

[0019] 1, the binding pieces 40 extend upward from the lower ends of the annular portions 31 of the handles 30. The binding pieces 40 are formed in a shape and size that allows them to bind together the waste paper bundles on the upper side when the waste paper bundles are contained in the bag body 10 (for example, the state shown in FIG. 5(B)).

[0020] 4, the pair of binding pieces 40 are formed in a narrow rectangular shape. Furthermore, as will be described later, the binding pieces 40 have a sufficient length so that the pair of binding pieces 40 can be bound together when folded inward.

[0021] The bag body 10 has a pair of gusset portions 15 formed by folding inward from both widthwise ends of a synthetic resin sheet formed into a cylindrical shape by blow molding or the like. When the storage bag X is flattened so that the gusset portions 15 are sandwiched between the side surfaces 12 in the thickness direction of the bag body 10 (see FIGS. 1 and 2), the upper and lower ends of the overlapping sheets in the bag body 10 are sealed. For example, the upper and lower ends are cut at the same time as the synthetic resin sheets are heat-sealed using a well-known heat-sealing device. FIGS. 1 and 2 show seal lines (sealed portions) 16, 17 formed by heat-sealing the synthetic resin sheets.

[0022] After sealing in this manner, the sealed portion in the center of the upper end of the bag 10 is cut off. The cut portion is the opening 10A that appears at the top of the bag 10 when it is unfolded. The waste paper stack is placed inside through this opening 10A. The sealed portion of the lower end of the bag 10 becomes the bottom 11 of the bag 10.

[0023] That is, the opening 10A is the portion where the sealed portion at the center of the upper end of the bag body 10 has been cut away, and the bottom 11 is the sealed lower end.

[0024] In this embodiment, a notch 18 of a predetermined length is formed extending downward from the upper end of the bag body 10 so as to pass through a predetermined position P spaced widthwise outward from the inner end 151 (see FIG. 3) on the central side of the gusset portion 15. The notch 18 extends downward from both ends in the width direction of the central part of the upper end of the bag body 10. In other words, the notch 18 extends downward from both ends in the width direction of the covering piece 20 of the bag body 10. The notch 18 has an elongated shape of a predetermined width extending outward from the position P.

[0025] By cutting out the portion of bag body 10 that corresponds to cutout 18, the portion of bag body 10 that is outward in the width direction from cutout 18 becomes handle 30. Furthermore, the portion of gusset portion 15 from cutout 18 to inner end 151 becomes binding piece 40. Therefore, the sizes of covering piece 20, binding piece 40, and handle 30 are determined by the widthwise position of position P where cutout 18 is formed, the width size of cutout 18, the downward length of cutout 18, etc.

[0026] Figure 5 is a photographic image showing the appearance of the storage bag X from diagonally above one of the covering pieces 20 when a sufficient amount of waste paper is contained in the actual storage bag X. Figure 5(A) shows the state in which a pair of covering pieces 20 are folded onto the top surface of the waste paper stack, Figure 5(B) shows the state in which a pair of binding pieces 40 are folded onto the top side of the overlapping covering pieces 20, and Figure 5(C) shows the state in which the pair of binding pieces 40 are bound together.

[0027] Since the storage bag X is configured as described above, when a waste paper bundle is stored inside the bag body 10 as shown in Figure 5, the top surface of the waste paper bundle is covered by folding the pair of covering pieces 20 inward (see Figure 5(A)). Furthermore, by folding the other pair of binding pieces 40 inward and arranging them on top of the covering pieces 20 (see Figure 5(B)), and then binding each binding piece 40, it is possible to close a part of the opening 10A located on the other side of the waste paper bundle while firmly maintaining the state where it is covered by the covering pieces 20 (see Figure 5(C)).

[0028] With this configuration, it is possible to close the opening 10A at the top of the storage bag without using the handle 30 for bundling. [Explanation of symbols]
