Description

The present invention relates to bag roll holders.

For example, in commercial facilities such as supermarkets, polyethylene bag roll holders that can be freely used by purchasers are arranged on football stands for packing purchased products. Regarding polyethylene bags (hereinafter abbreviated as plastic bags), due to the growing awareness of hygiene among purchasers, the prevention of water dripping due to condensation on products that have been refrigerated or frozen, and the desire to avoid getting my cloth bags wet. Consumption is increasing.

In addition to commercial facilities, for example, at medical sites, plastic bags are used to dispose of infectious waste, so its consumption is increasing during the corona crisis.

By the way, when using a plastic bag, it is necessary to separate the plastic bag from the polyethylene bag roll holder and open one end of the plastic bag.

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

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

The main rotating shaft 101 is rotatably supported by, for example, a housing (not shown). Both ends of the U-shaped support member 102 are supported by, for example, 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 pulls out the plastic bag sheet 201 from the plastic bag roll 200 and presses the vicinity of the cut-off portion such as the perforation against the bent portion 103 of the support member 102. Thus, the plastic bag sheet (polybag) 201 can be separated from the plastic bag roll 200 . Then, the user opens the plastic bag by rubbing the opening of the plastic bag with his or her fingertips.

However, since the opening of the plastic bag is adhered by static electricity, it may be difficult to open it if the user's fingertips are dry. As a result, the user using the plastic bag is irritated, the work time on the soccer table is prolonged, and the plastic bag is damaged due to failure to open, resulting in waste. In addition, mis-opening of plastic bags at medical sites can lead to infection accidents during disposal of infectious waste.

Therefore, in commercial facilities such as supermarkets, cloths, sponges, special containers, etc. soaked with liquids such as alcohol disinfectants are often prepared on soccer tables in order to moisten the fingertips and make it easier to open plastic bags. many.

In addition, for example, Patent Document 1 describes, "In a general roll holder that has already been introduced in supermarkets, a rectangular plate material is used as a substrate, and vertical Between the left and right hooks, a plastic bag sliding part consisting of a shelf-shaped overhang to which silicon rubber having adhesive strength is attached is provided, and a plastic bag sliding part is provided below the plastic bag sliding part "A plastic bag opening device provided with an advertising paper storage section for storing advertising paper" is described.

JP 2020-55623 A

However, the method of preparing alcohol disinfectant, etc. for moistening the fingertips requires the preparation of cloths, sponges, special containers, etc. In addition, it is necessary to replenish the alcohol disinfectant, etc., so commercial facilities costly for

The plastic bag opening tool described in Patent Document 1 requires three behaviors: an action by the user to pull out the plastic bag, an action to rub the plastic bag against the plastic bag sliding portion, and an action to separate the plastic bag from the plastic bag roll. be.

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

The plastic bag roll holder 10 is a U-shaped support member having a main rotary shaft 11 that serves as the rotary shaft of the plastic bag roll 200, and a friction bent portion 13 for separating the plastic bag sheet (poly bag) 201 from the plastic bag roll 200. 12 and a ground wire 14 to be grounded. Note that FIG. 1 omits illustration of a housing for rotatably supporting the main rotating shaft 11 .

The main rotating shaft 11 is composed of, for example, two substantially conical parts, and the apexes of the two parts are threaded in a convex shape on one side and a concave shape on the other side. The apexes of the two parts are respectively inserted into the center of the plastic bag roll 200 from both open ends, and screwed together to fix the main rotating shaft 11 to the plastic bag roll 200. - 特許庁Since the main rotating shaft 11 is fixed to the plastic bag roll 200, it is interlocked with the rotation of the plastic bag roll 200 by pulling out the plastic bag sheet 201, and rotates at the same time. However, in the plastic bag roll holder 10 and the plastic bag roll holder 20 (described later), if the plastic bag roll 200 is rotatable with respect to the main rotary shaft 11, the main rotary shaft 11 interlocking with the rotation of the plastic bag roll 200 rotation is not essential (it is essential for 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-shaped support member 12 are supported by, for example, a housing (not shown) so as not to rotate together with the main rotating shaft 101 . Note that the distance between the longitudinal direction of the plastic bag roll 200 and the central portion of the support member 12 parallel thereto can be appropriately changed according to the diameter of the plastic bag roll 200 .

A friction bent portion 13 is provided at a central portion of the support member 12 parallel to the longitudinal direction of the plastic bag roll 200 . The friction bent portion 13 forms an upwardly convex bent portion in the central portion of the support member 12, and the bent portion generates friction against, for example, the plastic bag sheet 201 to prevent the plastic bag sheet 201 from slipping. It is formed by covering with a non-slip member such as silicone rubber. The anti-slip member is not limited to silicone rubber, but may be rubber, plastic having an anti-slip surface, or metal with an anti-slip surface. can be changed. Alternatively, the bent portion of the support member 12 may be directly treated with a non-slip surface.

A ground wire 14 is connected to the support member 12 . As a result, the static electricity generated in the plastic bag sheet 201 flows to GND via the support member 12 and the ground wire 14, so that the static electricity generated in the plastic bag sheet 201 causes the plastic bag to adhere and is difficult to open. can prevent it from happening. A switch may be provided in the middle of the ground wire 14 so that the grounding function can be turned on and off. Alternatively, the main rotating shaft 11 may be made of a conductive material such as stainless steel, and the ground 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 out the plastic bag sheet 201 from the plastic bag roll 200 , presses it against the frictional bent portion 13 of the support member 12 , moves it left and right, and pulls it downward to remove the plastic bag sheet 201 from the plastic bag roll 200 . The plastic bag sheet (poly bag) 201 is separated. When the plastic bag sheet 201 is pressed against the friction bent portion 13 and moved left and right, the movement of the lower surface of the plastic bag sheet 201 is hindered by the friction with the friction bent portion 13. The sheet and the lower sheet are rubbed against each other. As a result, the plastic bag is separated from the plastic bag roll 200 in a state in which one end of the plastic bag is opened or in a state in which it becomes easy to open. Thus, 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 action.

In the plastic bag roll holder 10, the bent portion 103 of the conventional plastic bag roll holder 100 shown in FIG. 14 may be added.

<Modified example of plastic bag roll holder 10>
Next, FIG. 2 shows a modification of the plastic bag roll holder 10 according to the first embodiment of the present invention. Components common to the modified example and the plastic bag roll holder 10 (FIG. 1) are denoted by the same reference numerals, and descriptions thereof are omitted.

In this modification, the friction bending portion 13 provided in the support member 12 of the plastic bag roll holder 10 (FIG. 1) is formed linearly, and the straight central portion of the support member 12 is simply slipped with silicone rubber or the like. It replaces the friction part 15 covered with a stop member.

Since the method of using this modified example is the same as that of the plastic bag roll holder 10 (FIG. 1), the explanation thereof will be omitted. In the case of this modified example, unlike the plastic bag roll holder 10 (FIG. 1), there is no need to provide a protrusion at the central portion 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 a configuration example 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 denoted by the same reference numerals, and descriptions thereof are omitted.

The plastic bag roll holder 20 includes a main rotary shaft 11 that serves as the rotary shaft of the plastic bag roll 200, a U-shaped support member 21, a moving friction portion 22 provided at the central portion of the support member 21, and a grounded ground wire. 14. In FIG. 3, the illustration of a housing for rotatably supporting the main rotating shaft 11 is omitted.

The moving friction portion 22 is formed in a cylindrical shape, and the support member 21 is passed through the inside thereof. The outer periphery of the moving friction portion 22 is covered with a non-slip member such as silicone rubber that generates friction against the plastic bag sheet 201 to prevent the plastic bag sheet 201 from slipping. Note that the number of moving friction portions 22 is not limited to one, and a plurality of moving friction portions 22 may be provided on the support member 21 .

FIG. 4 is a diagram for explaining the details of the moving friction portion 22. As shown in FIG. 4A shows a cross-sectional view of the moving friction portion 22 parallel to the longitudinal direction of the support member 21. FIG. The moving friction portion 22 is, for example, a cylindrical cam, and a guide groove 221 is formed on its inner circumference. It should be noted that the moving friction portion 22 is not limited to the cylindrical cam, and other mechanisms may be employed as long as they are mechanisms capable of converting their own rotational motion into linear reciprocating motion. Further, the moving friction portion 22 may be simplified so that only the rotational motion is performed with the support member 21 as the rotating shaft, and the linear reciprocating motion is not performed.

FIG. 2B shows a developed view of the cylindrical moving friction portion 22. As shown in FIG. As shown in FIG. 2B, the guide groove 221 is formed so as to make one reciprocation in the longitudinal direction of the moving friction portion 22 during one round of the inner circumference of the moving friction portion 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 arranged in the guide groove 221 .

4C shows the movement of the moving friction portion 22. FIG. As a premise, the support member 21 shall be fixed without moving to the left or right. When the moving friction portion 22 rotates in accordance with the pulling out of the plastic bag sheet 201, the moving friction portion 22 is supported by the guide groove 221 formed therein with the projection 211 of the supporting member 21 arranged therein. It reciprocates along the longitudinal direction of the member 21 . In this case, the guide groove 221 is formed so as to make one reciprocation in the longitudinal direction of the moving friction portion 22 during one revolution of the moving friction portion 22. Then, the moving friction portion 22 makes one reciprocating motion along the longitudinal direction of the support member 21 .

FIG. 1D shows an example of a method of realizing a plastic bag roll holder 20 using the conventional plastic bag roll holder 100 shown in FIG. That is, the moving friction part 22 is made up of two semi-cylindrical parts, the moving friction part 22 is attached so as to cover the bent part 103 of the plastic bag roll holder 100, and the ground wire 14 is added. The plastic bag roll holder 20 may be realized by:

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 out the plastic bag sheet 201 from the plastic bag roll 200 while pressing it against the moving friction part 22, and pulls it downward to separate the plastic bag sheet (polybag) 201 from the plastic bag roll 200. - 特許庁make it At this time, as the plastic bag sheet 201 is pulled out, the moving friction part 22 reciprocates left and right while rotating. Therefore, 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 in which one end of the plastic bag is opened or in a state in which it becomes easy to open. Thus, 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 action.

Compared to the plastic bag roll holder 10, the plastic bag roll holder 20 saves the user the trouble of simultaneously moving the plastic bag sheet 201 to the left and right when pulling it out.

<Modified example of plastic bag roll holder 20>
Next, FIG. 5 shows a modification of the plastic bag roll holder 20. As shown in FIG. 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 with 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, is provided on a part of the outer periphery of the brush support member 23, and is attached so that the tip thereof is in contact with the surface of the moving friction portion 22. It is Although the brush support member 23 is fixed without rotating in the example of FIG. 5, the brush support member 23 may rotate. In that case, it is desirable 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) is employed to rotate forward (rotate in the same direction) interlocking with the rotation of the main rotating shaft 11 or the rotation of the moving friction portion 22. You may rotate it, and you may reversely rotate it. Alternatively, the brush support member 23 may rotate freely without being interlocked with the main rotating shaft 11 or the moving friction portion 22 . Furthermore, instead of directly attaching the cleaning brush 24 to the brush support member 23, the cleaning brush 24 is provided on the entire circumference of a cylindrical member (not shown), and the cylindrical member is rotated around the brush support member 23 with the brush support member 23 as an axis. may be attached to In that case, the cylindrical member may be fixed to the brush support member 23 and rotated together with the brush support member 23, or may be fixed without rotating the brush support member 23 and only the cylindrical member may be rotated. good.

In the case of this modified example, it is possible to remove dirt, dust, etc. adhering to the moving friction part 22, thereby preventing malfunction of the moving friction part 22 caused by dust, dirt, etc. entering the moving friction part 22. be able to.

<Configuration example of the plastic bag roll holder 30 according to the third embodiment of the present invention>
Next, FIG. 6 shows a configuration example 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 denoted by the same reference numerals, and descriptions thereof are omitted.

The plastic bag roll holder 30 includes a main rotating shaft 11 that serves as the rotating shaft of the plastic bag roll 200, a sub-rotating shaft 32 that rotates in conjunction with the rotation of the main rotating shaft 11, and a friction part provided in the center of the sub-rotating shaft 32. 33, a transmission mechanism 34, and an earth wire 14 to be grounded. In FIG. 3, a housing for rotatably supporting the main rotating shaft 11 and the sub-rotating shaft 32 is omitted.

The sub-rotating shaft 32 is installed parallel to the main rotating shaft 11 . The friction portion 33 provided on the sub-rotating shaft 32 is made of, for example, a non-slip member such as silicon rubber that generates friction against the plastic bag sheet 201 to prevent the plastic bag sheet 201 from slipping.

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

Next, FIG. 7 is a diagram for explaining the rotation of the main rotating shaft 11 and the sub-rotating shaft 32. As shown in FIG. 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 auxiliary rotating shaft 32 via the transmission mechanism 34 . In the case of the same figure, since the belt as the transmission mechanism 34 is hung in a figure 8 shape, the sub-rotating shaft 32 rotates clockwise. It should be noted that the belt as the transmission mechanism 34 is not limited to the shape of the figure 8, but may be placed in the shape of the figure 0 depending on the application and the condition of the surface of the plastic bag sheet 201. FIG. In that case, the auxiliary rotating shaft 32 will rotate 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 out the plastic bag sheet 201 from the plastic bag roll 200 while pressing it against the friction portion 33 of the sub-rotating shaft 32 and pulls it downward. ) 201 is disconnected. At this time, as the plastic bag sheet 201 is pulled out, the main rotating shaft 11 rotates counterclockwise and the auxiliary rotating shaft 32 rotates clockwise. Since the movement is hindered by the friction with 33, the upper and lower sheets of the plastic bag sheet 201 rub against each other. As a result, the plastic bag is separated from the plastic bag roll 200 in a state in which one end of the plastic bag is opened or in a state in which it becomes easy to open. Thus, 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 action.

<Modified example of plastic bag roll holder 30>
Although illustration is omitted, a brush support member 23 and a cleaning brush 24 are added to the plastic bag roll holder 30 (FIG. 6) in the same manner as the modification of the plastic bag roll holder 20 shown in FIG. The dirt on the friction portion 33 of the rotary shaft 32 may be removed.

<Options applicable to plastic bag roll holders 10, 20, 30>
Next, FIG. 8 shows an example of options applicable to the plastic bag roll holders 10,20,30.

The option consists of a rotating shaft converting mechanism 51 and a rotating part 52 . The rotating shaft conversion mechanism 51 is composed of, for example, two bevel gears that are orthogonally meshed. ing. The rotating shaft conversion mechanism 51 converts the direction of rotation of the main rotating shaft 11 by 90 degrees and transmits it to the rotating portion 52 . The rotating portion 52 is designed to display arbitrary information such as advertisements, guidance, and shining patterns on its outer periphery.

When the plastic bag sheet 201 is pulled out from the plastic bag roll 200 by the user and the main rotary shaft 11 rotates, the rotating part 52 rotates in conjunction with it. Therefore, by looking at the rotating part 52, it is possible to easily confirm that the plastic bag sheet 201 is pulled out from the plastic bag roll 200, and it is expected that the action of the user who tries to bring back the plastic bag more than necessary can be suppressed. can. Alternatively, the inside of the rotating portion 52 may be hollowed out, and a sound generating means such as a bell may be placed therein for emitting a sound according to the rotation of the rotating portion 52 . In this case, the sound generating means emits a sound (because the bell rings) in accordance with the rotation of the rotating portion 52, so that in addition to the effects described above, the visually impaired can be notified of the position of the soccer table. Note that the sound generating means is not limited to a bell, and may be an electronic bell or the like that detects vibration or rotation and emits a sound according to the detection result.

In addition, as another option, the rotary shaft converting mechanism 51 and the rotating part 52 are replaced with the side of the main rotating shaft 11, or the main rotating shaft to which the rotating shaft converting mechanism 51 and the rotating part 52 are not attached. 11 is provided with a rotating part rotating in the same direction as the main rotating shaft 11 and the plastic bag roll 200 (for example, a running wheel, which is a toy for exercising rodents such as hamsters; not shown). , and a stuffed toy such as a hamster equipped with a sound generating means may be placed in the rotating part. The rotating part can be easily retrofitted to the conventional plastic bag roll holder 100 in addition to the plastic bag roll holders 10, 20 and 30, and the same effect as the rotating part 52 containing the sound generating means can be expected.

Furthermore, if it is only necessary to generate a sound according 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 modifications and options>
In the above description, the plastic bag roll holders 10, 20, 30 are horizontally arranged on a soccer table or the like, but the plastic bag roll holders 10, 20, 30 may be arranged vertically on a soccer table or the like. For example, it can be arranged on a wall surface or the like in any direction.

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

In addition to the plastic bag roll 200, the plastic bag roll holders 10, 20, and 30 can also be applied to hold bag rolls such as vinyl bag rolls formed in a roll of a sheet other than polyethylene.
