Description

The present invention relates to a bag roll holder.

For example, at supermarkets and other commercial facilities, the sacks where purchased products are packed into bags are equipped with polyethylene bag roll holders that customers can use freely. Consumption of polyethylene bags (hereafter abbreviated as "poly bags") is increasing due to reasons such as customers' growing awareness of hygiene, the need to prevent dripping of water caused by condensation on refrigerated or frozen products, and the desire to avoid getting cloth reusable bags wet.

In addition to commercial facilities, for example, in medical facilities, plastic bags are used to dispose of infectious waste, and consumption has increased during the COVID-19 pandemic.

When using a plastic bag, it is necessary to detach the bag from the polyethylene bag roll holder and open one end of the bag.

Figure 9 shows an example of a conventional polyethylene bag roll holder 100. The polyethylene bag roll holder 100 is for rotatably holding a polyethylene bag roll 200 in which a plurality of plastic bags are connected together and a plastic bag sheet 201 is formed in a roll shape with perforations or the like provided at the separation points. Hereinafter, the polyethylene bag roll holder 100 will be abbreviated as the plastic bag roll holder 100.

The plastic bag roll holder 100 is composed of a main rotating shaft 101 that serves as the rotating shaft of the plastic bag roll 200, and a U-shaped support member 102 that has a bent portion 103 for separating the plastic bag sheet (plastic bag) 201 from the plastic bag roll 200.

The main rotating shaft 101 is rotatably supported, for example, by a housing (not shown). Both ends of the U-shape of the support member 102 are supported, for example, by a housing (not shown) so as not to rotate together with the main rotating shaft 101.

In the case of the plastic bag roll holder 100, a user who wants to use a plastic bag can pull the plastic bag sheet 201 from the plastic bag roll 200 toward himself, while pressing the vicinity of the separation point, such as a perforation, against the bent portion 103 of the support member 102, thereby separating the plastic bag sheet (plastic bag) 201 from the plastic bag roll 200. Next, the user can open the plastic bag by rubbing the opening of the plastic bag with his or her fingertips.

However, because the opening of a plastic bag is sealed by static electricity, it can be difficult to open if the user's fingertips are dry. This can frustrate the user, prolong the work time on the lifting table, and cause waste if the bag is broken due to failure to open it. Furthermore, mistakes in opening plastic bags in medical settings can lead to infection accidents when treating infectious waste.

In response to this, supermarkets and other commercial facilities often have cloths, sponges, or special containers soaked in alcohol-based disinfectant or other liquids on the counters to make it easier to open plastic bags by moistening fingertips.

For example, Patent Document 1 describes a plastic bag opening device that "uses a rectangular plate as a base for a typical roll holder already used in supermarkets, provides hook sections on the left and right sides of the upper edge of the base that are detachable and hang vertically from the beams of the roll holder, provides a plastic bag sliding section consisting of a shelf-like protrusion with adhesive silicone rubber attached between the left and right hook sections, and provides an advertising paper storage section below the plastic bag sliding section for storing advertising paper."

JP 2020-55623 A

However, the method of preparing alcohol-based disinfectant for moistening fingertips requires the preparation of cloths, sponges, special containers, etc., and the need to replenish the alcohol-based disinfectant, which is costly for commercial facilities.

The plastic bag opening device described in Patent Document 1 requires three actions by the user: pulling out the plastic bag, rubbing the plastic bag against the plastic bag sliding part, and cutting the plastic bag off from the plastic bag roll.

The present invention was made in consideration of these circumstances, and aims to make it possible to separate a plastic bag from a roll of plastic bags and open one end of the bag in a single motion.

This application includes multiple means for solving at least some of the above problems, examples of which are as follows:

In order to solve the above problem, a bag roll holder according to one aspect of the present invention is a bag roll holder that holds a bag roll on which a bag sheet is wound in a roll shape, and includes a main rotation shaft that serves as the rotation shaft of the bag roll, a support member arranged opposite the main rotation shaft, and a friction portion provided on the support member that prevents the bag sheet from slipping when pulled out from the bag roll.

The support member may have a bent portion, and the friction portion may be provided at the bent portion of the support member.

The friction portion can rotate around the support member as the bag sheet is pulled out.

The friction portion rotates around the support member as an axis in response to the drawing out of the bag sheet, and can move back and forth in the longitudinal direction of the support member.

The friction part can be a cylindrical cam.

The support member can be a secondary rotating shaft, and the bag holder can be equipped with a transmission mechanism that rotates the secondary rotating shaft as the support member in conjunction with the rotation of the main rotating shaft.

The secondary rotating shaft, which serves as the support member, can rotate in the forward or reverse direction relative to the main rotating shaft in conjunction with the rotation of the main rotating shaft.

The bag roll holder can be equipped with a cleaning brush to remove dirt from the friction portion.

The bag roll holder can be equipped with an earth wire that removes static electricity generated on the bag sheet.

The bag roll holder may include a rotating part that rotates in conjunction with the rotation of the main rotating shaft.

The bag roll holder can be equipped with a sound generating means that generates sound in response to the rotation of the main rotating shaft.

According to the present invention, the process of separating a plastic bag from a roll and opening one end of the bag can be accomplished in a single motion.

Problems, configurations, and advantages other than those described above will become clear from the description of the embodiments below.

<Configuration example of the plastic bag roll holder 10 according to the first embodiment of the present invention>
FIG. 1 shows an example of the configuration of a plastic bag roll holder 10 according to a first embodiment of the present invention.

The plastic bag roll holder 10 is composed of a main rotating shaft 11 that serves as the rotating shaft of the plastic bag roll 200, a U-shaped support member 12 having a friction bending portion 13 for separating the plastic bag sheet (plastic bag) 201 from the plastic bag roll 200, and a ground wire 14 for grounding. Note that the housing for rotatably supporting the main rotating shaft 11 is not shown in FIG. 1.

The main rotating shaft 11 is made up of, for example, two roughly conical parts, and the apexes of the two parts are threaded so that one is convex and the other is concave. The apexes of the two parts are inserted into the center of the plastic bag roll 200 from both ends, and then screwed together, so that the main rotating shaft 11 is fixed to the plastic bag roll 200. Since the main rotating shaft 11 is fixed to the plastic bag roll 200, it rotates simultaneously in conjunction with the rotation of the plastic bag roll 200 caused by the plastic bag sheet 201 being pulled out. However, in the plastic bag roll holder 10 and the plastic bag roll holder 20 (described later), if the plastic bag roll 200 can rotate relative to the main rotating shaft 11, it is not essential that the main rotating shaft 11 rotate in conjunction with the rotation of the plastic bag roll 200 (it is essential in the plastic bag roll holder 30 (described later)).

The support member 12 is made of a conductive material such as stainless steel. Both ends of the U-shape of the support member 12 are supported by, for example, a housing (not shown) so that it does not rotate together with the main rotating shaft 101. The distance between the central portion of the support member 12, which is parallel to the longitudinal direction of the plastic bag roll 200, can be changed as appropriate according to the diameter of the plastic bag roll 200.

A friction bend 13 is provided in the center of the support member 12, which is parallel to the longitudinal direction of the plastic bag roll 200. The friction bend 13 is formed by forming an upwardly convex bend in the center of the support member 12, and covering the bend with an anti-slip material such as silicone rubber that generates friction against the plastic bag sheet 201 and prevents the plastic bag sheet 201 from slipping. The anti-slip material is not limited to silicone rubber, and may be, for example, rubber, plastic with an anti-slip surface shape, or metal with an anti-slip surface treatment, and can be changed appropriately according to the material of the plastic bag sheet 201. The bend of the support member 12 may also be directly treated with an anti-slip surface.

The earth wire 14 is connected to the support member 12. This allows static electricity generated in the plastic bag sheet 201 to flow to GND via the support member 12 and the earth wire 14, preventing the plastic bag from sticking together and becoming difficult to open due to static electricity generated in the plastic bag sheet 201. A switch may be provided in the middle of the earth wire 14 to turn the grounding function on and off. In addition, the main rotating shaft 11 may be made of a conductive material such as stainless steel, and the earth wire 14 may be connected to the main rotating shaft 11.

An example of how to use the plastic bag roll holder 10 will be described. A user who wants to use a plastic bag pulls the plastic bag sheet 201 out of the plastic bag roll 200 toward himself, and pulls it downward while pressing it against the friction bending portion 13 of the support member 12 and moving it left and right, thereby separating the plastic bag sheet (plastic bag) 201 from the plastic bag roll 200. When the plastic bag sheet 201 is pressed against the friction bending portion 13 and moved left and right, the sheet on the lower surface of the plastic bag sheet 201 is prevented from moving due to friction with the friction bending portion 13, so that the upper sheet and the lower sheet of the plastic bag sheet 201 are rubbed against each other. As a result, the plastic bag is separated from the plastic bag roll 200 with one end open or in a state where it is easy to open. In this way, by using the plastic bag roll holder 10, a user who wants to use a plastic bag can separate the plastic bag 201 from the plastic bag roll 200 and open one end of the plastic bag 201 in one movement.

The plastic bag roll holder 10 may be realized by forming a frictional bending portion 13 by covering the bending portion 103 of the conventional plastic bag roll holder 100 shown in FIG. 9 with an anti-slip material such as silicone rubber, and further by adding an earth wire 14.

<Modification of the plastic bag roll holder 10>
Next, Fig. 2 shows a modified example of the plastic bag roll holder 10 according to the first embodiment of the present invention. Components common to this modified example and the plastic bag roll holder 10 (Fig. 1) are given the same reference numerals and their explanations are omitted.

In this modified example, the friction bend 13 on the support member 12 of the plastic bag roll holder 10 (Fig. 1) is formed in a straight line, and the linear center portion of the support member 12 is simply replaced with a friction portion 15 covered with an anti-slip material such as silicone rubber.

The method of using this modified example is the same as that of the plastic bag roll holder 10 (Fig. 1), so a description thereof will be omitted. In the case of this modified example, compared to the plastic bag roll holder 10 (Fig. 1), there is no need to provide a protrusion in the center of the support member 12, so the manufacturing process can be simplified.

<Configuration example of the plastic bag roll holder 20 according to the second embodiment of the present invention>
Next, Fig. 3 shows an example of the configuration of a plastic bag roll holder 20 according to a second embodiment of the present invention. Components common to the plastic bag roll holder 20 and the plastic bag roll holder 10 (Fig. 2) are given the same reference numerals and their description will be omitted.

The plastic bag roll holder 20 is composed of a main rotating shaft 11 that serves as the rotating shaft of the plastic bag roll 200, a U-shaped support member 21, a moving friction part 22 provided in the center of the support member 21, and a grounded earth wire 14. Note that in FIG. 3, the housing for rotatably supporting the main rotating shaft 11 is not shown.

The moving friction part 22 is formed in a cylindrical shape, and the support member 21 penetrates through it. The outer periphery of the moving friction part 22 is covered with an anti-slip material such as silicone rubber that generates friction with the plastic bag sheet 201 and prevents the plastic bag sheet 201 from slipping. The number of moving friction parts 22 is not limited to one, and multiple moving friction parts 22 may be provided on the support member 21.

Figure 4 is a diagram for explaining the details of the moving friction part 22. Figure 4 (A) shows a cross-sectional view of the moving friction part 22 parallel to the longitudinal direction of the support member 21. The moving friction part 22 is, for example, a cylindrical cam, and a guide groove 221 is formed on its inner circumference. Note that the moving friction part 22 is not limited to a cylindrical cam, and other mechanisms may be used as long as they can convert the rotational motion of the moving friction part 22 into linear reciprocating motion. In addition, the moving friction part 22 may be simplified to a structure in which only rotational motion is performed around the support member 21 as the rotation axis, and linear reciprocating motion is not performed.

Figure (B) shows an exploded view of the cylindrical moving friction part 22. As shown in Figure (B), the guide groove 221 is formed so as to make one reciprocating movement in the longitudinal direction of the moving friction part 22 while making one revolution around the inner circumference of the moving friction part 22. The moving friction part 22 is attached to the support member 21 so that the protrusion 211 formed in the center of the support member 21 is positioned in the guide groove 221.

Figure (C) shows the movement of the moving friction part 22. As a premise, the support member 21 is fixed and does not move left or right. When the moving friction part 22 rotates in response to the drawing out of the plastic bag sheet 201, the protrusion 211 of the support member 21 is arranged in the guide groove 221 formed inside, so the moving friction part 22 moves back and forth along the longitudinal direction of the support member 21. In this case, the guide groove 221 is formed so as to make one reciprocating movement in the longitudinal direction of the moving friction part 22 while making one revolution around the inner circumference of the moving friction part 22, so that the moving friction part 22 moves one reciprocating movement along the longitudinal direction of the support member 21 while the moving friction part 22 makes one rotation.

Figure (D) shows an example of a method for realizing a plastic bag roll holder 20 using the conventional plastic bag roll holder 100 shown in Figure 9. That is, the moving friction part 22 may be constructed from two semi-cylindrical parts, the moving friction part 22 may be attached so as to cover the bent part 103 of the plastic bag roll holder 100, and an earth wire 14 may be added to realize the plastic bag roll holder 20.

An example of how to use the plastic bag roll holder 20 will be described. A user who wants to use a plastic bag pulls the plastic bag sheet 201 from the plastic bag roll 200 toward himself while pressing it against the moving friction part 22, and pulls it downward to separate the plastic bag sheet (plastic bag) 201 from the plastic bag roll 200. At this time, the moving friction part 22 moves back and forth from side to side while rotating in response to the pulling out of the plastic bag sheet 201, and the upper sheet and the lower sheet of the plastic bag sheet 201 are rubbed against each other because the movement of the lower sheet of the plastic bag sheet 201 is hindered by friction with the moving friction part 22. As a result, the plastic bag is separated from the plastic bag roll 200 in a state where one end of the plastic bag is open or easy to open. In this way, by using the plastic bag roll holder 20, a user who wants to use a plastic bag can separate the plastic bag 201 from the plastic bag roll 200 and open one end of the plastic bag 201 in one movement.

Compared to the plastic bag roll holder 10, the plastic bag roll holder 20 eliminates the need for the user to simultaneously move the plastic bag sheet 201 left and right when pulling it forward.

<Modification of the plastic bag roll holder 20>
Next, Fig. 5 shows a modified example of the plastic bag roll holder 20. In this modified example, a brush support member 23 and a cleaning brush 24 are added to the plastic bag roll holder 20 (Fig. 3).

The brush support member 23 is attached parallel to the support member 21 at a predetermined distance from the support member 21. The cleaning brush 24 is for wiping the surface of the moving friction portion 22 to remove dirt, and is attached to a part of the outer periphery of the brush support member 23 with its tip attached so as to contact the surface of the moving friction portion 22. In the example of FIG. 5, the brush support member 23 is fixed without rotating, but the brush support member 23 may be rotated. In that case, it is preferable that the cleaning brush 24 is provided on the entire circumference of the brush support member 23 (not shown). When rotating the brush support member 23, for example, a transmission mechanism 34 (FIG. 6, described later) may be adopted to rotate the brush support member 23 forward (rotate in the same direction) in conjunction with the rotation of the main rotating shaft 11 or the moving friction portion 22, or to rotate it in the opposite direction. The brush support member 23 may also be rotated freely without being linked to the main rotating shaft 11 or the moving friction portion 22. Furthermore, instead of attaching the cleaning brush 24 directly to the brush support member 23, the cleaning brush 24 may be provided around the entire circumference of a cylindrical member (not shown), and the cylindrical member may be attached around the brush support member 23 with the brush support member 23 as its axis. In this case, the cylindrical member may be fixed to the brush support member 23 and rotated together with the brush support member 23, or the brush support member 23 may be fixed without rotating and only the cylindrical member may be rotated.

In this modified example, dirt, dust, etc. adhering to the moving friction part 22 can be removed, and malfunctions of the moving friction part 22 caused by dirt, dust, etc. entering the inside of the moving friction part 22 can be prevented.

<Configuration example of the plastic bag roll holder 30 according to the third embodiment of the present invention>
Next, Fig. 6 shows an example of the configuration of a plastic bag roll holder 30 according to a third embodiment of the present invention. Components common to the plastic bag roll holder 30 and the plastic bag roll holders 10 (Fig. 1) and 20 (Fig. 3) are given the same reference numerals and their explanations are omitted.

The plastic bag roll holder 30 is composed of a main rotating shaft 11 which is the rotating shaft of the plastic bag roll 200, a secondary rotating shaft 32 which rotates in conjunction with the rotation of the main rotating shaft 11, a friction part 33 provided in the center of the secondary rotating shaft 32, a transmission mechanism 34, and a ground wire 14 which is grounded. Note that in FIG. 3, the housing for rotatably supporting the main rotating shaft 11 and secondary rotating shaft 32 is not shown.

The secondary rotating shaft 32 is installed parallel to the main rotating shaft 11. The friction portion 33 provided on the secondary rotating shaft 32 is made of an anti-slip material such as silicone rubber that generates friction with the plastic bag sheet 201 to prevent the plastic bag sheet 201 from slipping.

The transmission mechanism 34 is, for example, a belt, a chain, a wire, a gear, etc., and transmits the rotation of the main rotating shaft 11 to the sub rotating shaft 32. In the case of the same figure, the transmission mechanism 34 is a belt that is hung in an eight-shape across the main rotating shaft 11 and the sub rotating shaft 32.

Next, FIG. 7 is a diagram for explaining the rotation of the main rotating shaft 11 and the sub-rotating shaft 32. When the user pulls out the plastic bag sheet 201, the plastic bag roll 200 and the main rotating shaft 11 rotate counterclockwise, and the rotation of the main rotating shaft 11 is transmitted to the sub-rotating shaft 32 via the transmission mechanism 34. In the case of the figure, the belt as the transmission mechanism 34 is wound in an eight-shape, so that the sub-rotating shaft 32 rotates clockwise. Note that the way in which the belt as the transmission mechanism 34 is wound is not limited to an eight-shape, and it may be wound in a zero-shape depending on the application and the surface condition of the plastic bag sheet 201. In that case, the sub-rotating shaft 32 rotates counterclockwise like the main rotating shaft 11.

An example of how to use the plastic bag roll holder 30 will be described. A user who wants to use a plastic bag pulls the plastic bag sheet 201 from the plastic bag roll 200 toward himself while pressing it against the friction part 33 of the secondary rotating shaft 32, and pulls it downward to separate the plastic bag sheet (plastic bag) 201 from the plastic bag roll 200. At this time, the main rotating shaft 11 rotates counterclockwise and the secondary rotating shaft 32 rotates clockwise in response to the pulling out of the plastic bag sheet 201, so that the sheet on the lower surface of the plastic bag sheet 201 is prevented from moving due to friction with the friction part 33, and the upper sheet and the lower sheet of the plastic bag sheet 201 are rubbed against each other. As a result, the plastic bag is separated from the plastic bag roll 200 in a state where one end of the plastic bag is open or easy to open. In this way, by using the plastic bag roll holder 30, a user who wants to use a plastic bag can separate the plastic bag 201 from the plastic bag roll 200 and open one end of the plastic bag 201 in one movement.

<Modification of the plastic bag roll holder 30>
Although not shown, similar to the modified example of the plastic bag roll holder 20 shown in Figure 5, a brush support member 23 and a cleaning brush 24 may be added to the plastic bag roll holder 30 (Figure 6) so that dirt can be removed from the friction portion 33 of the secondary rotating shaft 32.

<Options applicable to the plastic bag roll holders 10, 20, and 30>
Next, FIG. 8 shows an example of an option that can be applied to the plastic bag roll holders 10, 20, and 30.

This option consists of a rotation axis conversion mechanism 51 and a rotating unit 52. The rotation axis conversion mechanism 51 consists, for example, of two bevel gears meshed at right angles, and is arranged so that one bevel gear rotates with the main rotating shaft 11 and the other bevel gear rotates with the rotating unit 52. The rotation axis conversion mechanism 51 converts the rotation direction of the main rotating shaft 11 by 90 degrees and transmits it to the rotating unit 52. The rotating unit 52 is designed to be able to display any information such as advertisements, guidance, and glowing patterns on its outer periphery.

When the user pulls out the plastic bag sheet 201 from the plastic bag roll 200 and the main rotating shaft 11 rotates, the rotating part 52 rotates in conjunction with the pull. Therefore, by looking at the rotating part 52, it is easy to see from the surroundings that the plastic bag sheet 201 is being pulled out from the plastic bag roll 200, and it is expected to have the effect of suppressing the behavior of users who try to take home more plastic bags than necessary. In addition, the inside of the rotating part 52 may be hollowed out and a sound generating means such as a bell that emits a sound in response to the rotation of the rotating part 52 may be placed inside it. In that case, since the sound generating means emits a sound in response to the rotation of the rotating part 52 (the bell rings), in addition to the above-mentioned effect, it is possible to inform the visually impaired of the location of the soccer table. In addition, the sound generating means is not limited to a bell, and may be an electronic bell that detects vibrations or rotation and emits a sound in response to the detection result.

As another option, instead of the rotation axis conversion mechanism 51 and the rotating part 52, a rotating part (such as a running wheel, which is a toy for exercising rodents such as hamsters; not shown) that rotates in the same direction as the main rotating shaft 11 and the plastic bag roll 200 may be attached to the side of the main rotating shaft 11, or to the side of the main rotating shaft 11 to which the rotation axis conversion mechanism 51 and the rotating part 52 are not attached, and a stuffed animal such as a hamster equipped with a sound generating means may be placed inside the rotating part. The rotating part can be easily retrofitted to the conventional plastic bag roll holder 100 as well as the plastic bag roll holders 10, 20, and 30, and the same effect as the rotating part 52 equipped with a sound generating means can be expected.

Furthermore, if sound is only to be generated in response to the rotation of the main rotating shaft 11, for example, a cavity may be provided inside the main rotating shaft 11 and a sound generating means may be placed in the cavity.

<Other variations and options>
In the above description, the plastic bag roll holders 10, 20, 30 are arranged horizontally on a soccer table or the like, but the plastic bag roll holders 10, 20, 30 can be arranged vertically on a soccer table or the like, or can be arranged in any orientation, for example, on a wall surface, etc.

The plastic bag roll holders 10, 20, and 30 may be combined with a cellophane tape stand, a packing string box, or the like. Also, to prevent theft, the plastic bag roll holders 10, 20, and 30 may be fixed to a locking stand or the like and locked.

The plastic bag roll holders 10, 20, and 30 can be used to hold not only the plastic bag roll 200, but also bag rolls in which sheets other than polyethylene are formed into a roll shape, such as vinyl bag rolls.

The present invention is not limited to the above-described embodiment and modifications, and various other modifications are possible. For example, the above-described embodiment and modifications have been described in detail to clearly explain the present invention, and are not necessarily limited to those having all of the configurations described. In addition, it is possible to replace part of one modification with another modification, or to combine modifications.
