Description

  The present invention relates to a storage aid for a bag for making it easy to store garbage in bags for various uses, for example, garbage bags.

  For example, a commercially available garbage bag is formed from a thin sheet made of synthetic resin whose size, material, etc. are predetermined by the local government, but stores sharp-pointed items such as twigs and timbers. There was a problem that the garbage bags were easily torn because their tips were pierced.

  Therefore, for example, as shown in Patent Document 1 below, the above problem is solved by inserting and inflating a thin plate having elasticity and a strong and hard property into the garbage bag so as to cover the inner surface of the garbage bag. However, there is a tree garbage storage device that prevents the rubbish bag from being torn even when a pointed object such as a twig or a piece of wood is inserted. Moreover, as shown in the following Patent Document 2, there is a framework in which a plastic bag can be made self-supporting by being put in a plastic bag and expanded in the plastic bag and used as it is as a waste box.

  However, the tree garbage storage device of Patent Document 1 can protect the garbage bag from tearing, but it is not easy to insert an elastic and hard thin plate into the garbage bag. The problem remains that it is more difficult to work with. Further, in the framework disclosed in Patent Document 2, the garbage bag cannot be protected from the damage as described above, and is difficult to pull out from the garbage bag. Remains.

  In order to solve these problems, the present applicant, as shown in the cited document 3, the base made of a hard plate curved in a substantially semicircular shape, and both side edges inscribed in the base are bent to both side edges of the base. A flexible plate that is freely connected, and inserting the base body into a garbage bag and projecting the flexible plate outward, whereby the base body and the flexible plate are connected to the inner surface of the garbage bag. Invented a storage aid for a bag in which the garbage bag can be expanded in contact with the bag.

  However, the bag storage aid of Patent Document 3 is composed of two members: a base that is curved in a substantially semicircular shape, and a flexible plate that is flexibly connected to both side edges of the base. Since these are connected and formed, the formation is troublesome, and the base is bulky, resulting in high manufacturing costs and transportation costs, and it is difficult to insert into a garbage bag and is difficult to use. There was a point.

  Therefore, the present invention has been made in view of the above-mentioned improvements, and is simple in structure and formation, and can be freely bent and folded in a compact manner, so that not only manufacturing costs and transportation costs can be reduced, but also in the bag. It is also intended to provide a storage aid for a bag that can be easily inserted and is extremely convenient to use.

  In order to achieve such an object, the bag storage aid according to the present invention is provided with a plurality of ribs extending in one direction between two parallel sheets and connecting the two sheets. From a cylindrical body formed by curving a plastic corrugated board having hard elasticity in which a large number of cavities are partitioned and formed in rows by each rib so that each rib is orthogonal to the circumferential direction The inner sheet of the cylindrical body is provided with recessed grooves that are recessed along the longitudinal direction corresponding to the hollow portions that are spaced apart from each other by a predetermined distance along the circumferential direction. In this case, the bag is expanded by its elasticity and held in an expanded state by being inserted into the bag while being bent and folded along.

  Further, the bag storage aid according to the present invention is provided with a plurality of ribs extending in one direction between two parallel sheets, and connecting the two sheets. A cylindrical body formed by curving a plastic corrugated board having hard elasticity in which the hollow portions of the ribs are formed in a row so that the ribs are orthogonal to the circumferential direction. The inner sheet or the outer sheet of the sheet-like body has a recess which is recessed along the longitudinal direction corresponding to each of the cavities located at a predetermined distance along the circumferential direction and whose deepest portion is connected to the sheet facing the cavity. A groove is provided and inserted into the bag while being bent and folded along the groove so that the bag is expanded by its elasticity and held in an expanded state. With the feature that It may be configured that.

  The storage aid in the bag according to the present invention is molded from a plastic corrugated board, is simple in structure and formation, and is folded compactly by being bent along the recessed groove, so that it is lightweight without being bulky. Not only is it convenient for transportation and storage, but also manufacturing costs and transportation costs can be reduced. In addition, since it can be folded compactly, it is easy to insert it into a bag such as a garbage bag, and it is very convenient to use.

  Further, in the inner or outer sheet of the cylindrical body, a sheet that is recessed along the longitudinal direction corresponding to each of the hollow portions that are spaced apart by a predetermined distance along the circumferential direction, and the deepest part of the sheet is opposed thereto. If the recessed grooves to be connected are provided, the plastic corrugated board is bent with the deepest part of each recessed groove as a fulcrum, so the plastic corrugated board can be either inside or outside with the deepest part as a fulcrum. Even bend easily. Therefore, for example, when the cylindrical body is formed from a plastic corrugated board developed in a rectangular shape, it is not necessary to consider whether it bends inward or outward, so that the assembly work can be performed easily.

  Hereinafter, the best mode for carrying out a storage aid for a bag according to the present invention (hereinafter, simply referred to as “storage aid”) will be described in detail with reference to the drawings. The present invention is, for example, a garbage bag made of a thin synthetic resin sheet used at home, a garbage bag that is placed in an appropriate position in a kitchen and contains raw garbage generated by cooking, a packaging bag that stores vegetables such as radish and burdock, etc. Applicable for bags for disposal or packaging. The material of the bag is mainly a synthetic resin, but other materials such as paper and cloth may be used. Therefore, as an example, a waste synthetic resin garbage bag having a width of 650 mm and a depth of 750 mm used at home will be described. FIG. 1 is an external perspective view of a storage aid according to the present embodiment, and FIG. 2 is a partially enlarged perspective view of the storage aid according to the present embodiment. This storage aid uses a hard and elastic plastic corrugated board 1 (generally referred to as “pradan”), which makes the plastic corrugated board 1 rectangular and bends it. It is formed by winding in a cylindrical shape.

  More specifically, the plastic corrugated board 1 is provided with a plurality of ribs 3 extending in one direction between two parallel sheets 2 and 2 and connecting both the sheets 2 and 2. The structure is such that a large number of cavities 4 are partitioned and formed in rows by the ribs 3 between the two. Usually, it is formed by extrusion molding using a die (not shown) shaped like a ladder. For example, polypropylene resin is used as the material, but polyvinyl chloride resin or polyethylene resin may also be used. The thickness of the sheet 2 or rib 3 is set to 0.1 mm, for example, the distance between adjacent ribs 3 and 3 is set to 3.0 mm, for example, and the thickness of the plastic corrugated board 1 is set to 2.5 mm, for example. Is done. Since the plastic corrugated board 1 is hard and elastic, it returns to its original state even when bent.

  One side of the plastic corrugated board 1, in this case, the inner sheet 2 (2 a) of the cylindrical body 6, which will be described later, has a longitudinal direction corresponding to each cavity 4 a that is spaced apart along the circumferential direction by a predetermined distance. A recessed groove 7 that is recessed along the direction is provided. In this case, each cavity 4 corresponds to each cavity 4a located in a direction perpendicular to each rib 4, that is, three cavities 4, 4 and 4 which are continuous along the direction and spaced apart from each other. A concave groove 7 parallel to the rib 3 is provided in the inner sheet 2 (2a). The deepest portion 7a of the recessed groove 7 is in contact with and not in contact with the outer sheet 2b facing the groove 7a. The concave groove 7 is provided in this way so that the plastic corrugated board 1 can be easily bent to the side where the concave groove 7 is provided. Although the recessed groove 7 is provided with a gap between the three cavities 4, 4, 4 separated from each other, the present invention is not limited to this. For example, 4, 5, 6, 7, 8 Alternatively, the recessed groove 7 may be provided by separating the gaps 4 of the cavity portion 4 more than that, and can be freely set as long as the object of the present invention can be achieved.

  Therefore, in the rectangular plastic corrugated board 1, the ribs 3 are arranged in parallel along the short direction. Then, by overlapping and connecting both end edges 11a and 11b in the longitudinal direction, a cylindrical body 6 is formed in which each rib 3 is arranged so as to be orthogonal to the circumferential direction and both ends are opened 5 and 5. Each recessed groove 7 is arranged to come to the inner peripheral surface 6 a side of the cylindrical body 6. In this case, both end edge portions 11a and 11b to which the plastic corrugated board 1 is connected partially overlap the inner peripheral surface 6a of one end edge portion 11a and the outer peripheral surface 6b of the other end edge portion 11b, The three cavities 4, 4, and 4 are bonded with an adhesive so as to overlap each other. Thereby, it corresponds to the inner peripheral surface 6a of the cylindrical body 6, that is, each cavity portion 4a located at a distance apart from the total spacing of the three cavity portions 4, 4, 4 continuous along the circumferential direction. The inner sheet 2 (2a) is provided with a concave groove 7 parallel to the longitudinal direction thereof, that is, the rib 3. Each of the recessed grooves 7 is formed in a V-shaped cross section perpendicular to the longitudinal direction. The cylindrical body 6 is set to have an outer diameter dimension of about 10 to 30 mm shorter than an inner diameter dimension of the insertion port 10 of the garbage bag 9 when the cylindrical body 6 is formed into a cylindrical shape. Reference numerals 8 and 8 are hand-held through holes formed from the upper end of the cylindrical body 6.

  As shown in FIG. 3, the storage aid configured in this manner is bent along a desired concave groove 7 and compactly folded before being inserted into a garbage bag 9 made of a thin synthetic resin sheet. Then, the folded storage aid is inserted into the garbage bag 9 through the insertion port 10. When a force is applied to open the storage aid in the garbage bag 9, the storage aid naturally expands due to its elasticity, and the waste bag 9 is held in an expanded state as shown in FIG. The That is, in this state, the garbage bag 9 stands on the ground with the insertion port 10 opened.

  Therefore, as shown in FIG. 5, it is possible to easily put garbage into a self-supporting garbage bag 9 from the insertion port 10 like a garbage box. Since it only hits the inner peripheral surface 6a of the body 6, there is no possibility that the garbage bag 9 will be torn. Even if it is pointed garbage, it can be stored in a large amount without being bulky by stepping on the foot and compressing it. If the hand is put in the through-holes 8 and 8 and the storage aid is lifted and pulled out when the garbage is full, the garbage bag 9 can be easily extracted because the weight of the garbage is applied to the bottom. Since only the garbage remains in the garbage bag 9, the garbage bag 9 can be taken out as it is by simply tying the insertion port 10 of the garbage bag 9 normally. In addition, since the cylindrical body 6 is a polypropylene resin and is flat and easy to slide, the storage aid can be easily extracted from the garbage bag 9 with light friction. For this reason, by using this storage aid, it is not necessary to transfer the trash into a trash bag like a normal trash can, and the trash can be easily discharged without placing a burden on the operator.

  The storage aids shown in FIGS. 6 to 9 are all related to other embodiments. Therefore, since these components are almost the same as those in the present embodiment, the same parts as those in the present embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. The storage aid shown in FIG. 6 is configured such that both end edges 11a and 11b along the longitudinal direction of the rectangular plastic corrugated board 1 can be detachably connected. That is, when the plastic corrugated board 1 is curved in a cylindrical shape, a male mold is attached to the upper and lower ends of the inner peripheral surface of one end edge 11a along the longitudinal direction of the plastic corrugated board 1 Fasteners 12 and 12 are attached, and female bonded fasteners are positioned at the upper and lower ends of the outer peripheral surface of the other edge 11b along the longitudinal direction so as to correspond to the male bonded fasteners 12 and 12, respectively. 13 and 13 are attached. And the cylindrical body 6 is formed by bonding these female | male type | mold bonding fasteners 12 and 13 and connecting the both-ends edge parts 11a and 11b.

  The storage aid can also be used in the same manner as the storage aid according to the present embodiment. Thus, both ends 11a and 11b of the plastic corrugated board 1 are detachably connected. For example, when the plastic corrugated board 1 is shipped from a manufacturing factory, the plastic corrugated board 1 is stacked in a rectangular state. This is because if the packaging is used, the volume can be reduced, the transportation efficiency is good, and the transportation cost can be reduced. Further, the plastic corrugated board 1 can be conveniently used for a sheet as a rug.

  The storage aid shown in FIG. 7 is obtained by fitting a protective cover 14 having a substantially U-shaped cross section perpendicular to the longitudinal direction to the entire annular upper and lower end edges of the cylindrical body 6. The protective cover 14 is made of a soft synthetic resin material. The upper and lower ends of the cylindrical body 6 are merely cut from the plastic corrugated board 1 and the upper and lower ends of the inner and outer sheets 2a and 2b are sharp like a razor. For this reason, even if the plastic corrugated board 1 is formed of a synthetic resin material, there is a risk of injury such as cutting the hand by touching the edge, so that the risk is prevented. Further, the inner and outer sheets 2a and 2b, that is, both ends of the hollow portions 4 and 4a are sealed. Thereby, it can be handled cleanly without water entering the inside, and is particularly useful as a storage aid for a garbage bag for storing garbage used in the kitchen. This protective cover 14 can also be used for the removable storage aids according to the other embodiments and the storage aids according to other embodiments described later.

  Further, the storage aid shown in FIG. 8 directly heats the entire upper and lower end edges of the cylindrical body 6 without fitting the protective cover 14 around the periphery of the openings 5 and 5 at both ends of the cylindrical body 6 as described above. It is sealed by fusion. That is, as shown in FIG. 8, the upper and lower end edges of the inner sheet 2 a and the outer sheet 2 b are curved and approached to each other, and heat fusion is performed in a state where they are in contact with each other, thereby making the heat fusion portion 15 Forming. As a result, the inner and outer sheets 2a and 2b are sealed, that is, both ends of the cavities 4 and 4a are sealed. Also in this case, safety in use is ensured and water can be handled cleanly without entering water.

  FIG. 9 (a) is a partially enlarged end view of a plastic cardboard board according to another embodiment, and FIG. 9 (b) is a partially enlarged perspective view of a storage aid using the plastic cardboard board. In the plastic corrugated board 1A according to this embodiment, a predetermined interval dimension along the circumferential direction, that is, a continuous 3 in one side surface, in this case, the outer sheet 2 (2b) in the cylindrical body 6 is provided. A concave groove 7A that is recessed along the longitudinal direction is provided corresponding to each of the cavity portions 4a that are spaced apart from each other and are spaced apart from each other. Each concave groove 7A has a V-shaped cross section perpendicular to the longitudinal direction, and the deepest portion 7Aa of these concave grooves 7A is connected to the inner sheet 2 (2a) facing this. .

  When the deepest portion 7Aa in the V-shaped recessed groove 7A is formed integrally with the inner sheet 2 (2a), the deepest portion 7Aa formed integrally is a fulcrum, and FIG. As shown in FIG. 5, the plastic corrugated board 1A can be easily bent either inside or outside with the deepest portion 7Aa of each recessed groove 7A as a fulcrum. Therefore, when forming the cylindrical body 6, it is possible to freely select whether the recessed groove 7A appears on the inner peripheral surface 6a of the cylindrical body 6 or conversely appears on the outer peripheral surface 6b. The storage aid thus formed can also be used in the same manner as the storage aid according to the present embodiment. Therefore, for example, when the cylindrical body 6 is formed from the plastic corrugated board 1A developed in a rectangular shape, it is not necessary to consider whether the plastic cardboard board 1A is bent inward or outward. Is easy to do.

  As described above, the storage aid according to the present invention is molded from the plastic corrugated board 1 and 1A, is simple in structure and formation, and is folded compactly by being bent along the recessed grooves 7 and 7A. Since it is light and free, it is convenient not only for transportation and storage but also for low manufacturing costs and transportation costs. In addition, since the storage aid according to the present invention can be folded compactly, it can be easily inserted into a bag such as a trash bag, and can be easily set by one person and is extremely convenient.

  In addition, this storage aid is economical because it can be used repeatedly for a certain period after being extracted from the garbage bag 9. Moreover, since the garbage bag 9 can be made independent like a garbage can, it can be used for beautification of the environment by placing it in an office, room, or outdoors as an alternative to the garbage can.
