The storage tank is a tank for storing game balls that are lent to a player and game balls that are paid out as prize balls to the player for winning a prize at a winning opening. When the number of game balls in the storage tank decreases, game balls are supplied from the upper tank 70 of the gaming machine installation island 1 through a basket (not shown).

  In addition, as shown in FIG. 1, in the lifting device 100 of the present embodiment, in particular, the portions of the lifting pipes 110, 120, and 130 can be installed inside the back surface of the pachinko gaming machine 10. For this reason, since it is not necessary to provide an extra width for the lifting device 100 on the gaming machine installation island 1, the pachinko gaming machine 10 and the card unit 20 can be installed without a gap. Therefore, more pachinko gaming machines 10 can be installed as much as it does not require extra space for the lifting device 100, so that sales at the amusement store can be improved.

  Referring to FIGS. 3 to 10, the lifting pipe 110 includes a plurality of (here, five) paper pipes 111, pipe joints 112 and 113, a paper pipe case 119, connection portions 114 and 115, Opening and closing type pipe stoppers 116 and 117 and a pipe holding portion 118 are provided.

  The lifting pipes 110 and 130 are connected by fitting the respective connecting portions 115 and 131. Similarly, the lifting pipe 120 is fitted and connected to the connecting portion 114 of the lifting pipe 110.

  Next, dirt that adheres to the game ball will be described. Table 1 is a table showing the components of dirt attached to the transporting pipe and the basket through which the game ball passes. Table 2 is a table showing the components of dirt when moisture is removed from dirt adhering to the lifting pipe and the basket through which the game ball passes. The dirt adhering to the lifting pipe and the basket is a transfer of the dirt adhering to the game ball. The foreign matter A, the foreign matter B, and the foreign matter C are different stains at different locations.

  Referring to Table 1 and Table 2, the oil component is derived from mineral oil applied to each part through which the game ball passes and sebum such as a player and a game shop clerk. The water-insoluble substance is derived from fiber components such as clothes of players and amusement clerk and cleaning tools. C, O and Na are derived from sodium lactate which is a lactate. Mg, Al, Si, S, Cl, K, Ca, Cr, Ni, and Cu are derived from salts other than lactate.

  Based on the data in Table 2, the components derived from sodium lactate in the foreign matter A, foreign matter B, and foreign matter C from which moisture was removed were 35.3%, 39.9%, and 42.2%, respectively. It occupies a high rate of around 40%. For this reason, if sodium lactate can be removed effectively, most of the dirt adhering to the game ball can be removed effectively.

  Here, the lactate such as sodium lactate is firmly attached to an attached object (for example, a game ball) when moisture is removed. As in Patent Document 1, in the pipe-type polishing apparatus, unless the material of the polishing member used for the inner surface of the pipe is specified, moisture is also removed from the dirt components attached to the game ball. It makes it difficult to remove lactate from the dirt attached to the game ball. Therefore, in order to remove the dirt, it is important to leave moisture appropriately.

  Further, in the present embodiment, cardboard is used as the material of the pipe of the lifting pipe 110. The reason for this is as follows. The cardboard has moderate flexibility. For this reason, as shown in FIG. 4, the flexible part of the paper pipe 111 which is not fixed is lifted by providing the part which is fixing the paper pipe 111, and the part which is not fixing. Deflection by the movement of the game ball. This bending promotes contact between game balls, and contact between the biodegradable material layer (specific component layer) on the inner surface of the paper pipe 111 and the game ball, and also promotes changes in the contacted portion (biodegradation). Is done. As a result, it is possible to promote the removal of dirt from the game ball and improve the polishing effect.

  However, if only the paper pipe 111 is used as the lifting pipe 110, the water vapor permeability becomes high, and moisture adhering to the game ball flowing through the inside is diffused to the outside of the paper pipe 111. This further promotes the sticking of lactate to the game ball. In order to solve such a problem, in this embodiment, a specific component layer having a relatively low water vapor permeability is used as the polishing member on the inner surface of the paper pipe 111 of the lifting pipe 110. Here, the specific component layer preferably has a water vapor permeability of 1000 g / m 2 · 24 h or less at 40 ± 0.5 ° C. and 90 ± 2% RH.

  FIG. 11 is a diagram illustrating the structure of the paper pipe 111 of the lifting pipe 110 according to the first embodiment. With reference to FIGS. 11A and 11B, the paper pipe 111 includes a cylindrical body 1112 serving as a base of the paper pipe 111 and a specific component layer formed inside the cylindrical body 1112. A game ball 11 flows inside the paper pipe 111.

  Here, the specific component layer is preferably a polyester-based decomposable resin, a natural polysaccharide, or an animal or vegetable resin alone or a mixture of a plurality thereof. According to this, when the specific component layer biodegrades, the inner surface of the pumping pipe gradually becomes rough with time, and a large amount of dirt adheres and the reduced adsorption power is restored. Since it becomes possible, the game ball 11 can be more appropriately polished inside the lifting pipe.

  The game ball 11 has a diameter of 11 mm. The cylinder 1112 has a thickness of 1 mm and an inner diameter of 12 mm. The specific component layer is formed by spirally winding a strip (film) having a width of 3 cm and a thickness of 30 μm. Moreover, the edges of adjacent strips are overlapped. In the present embodiment, the overlap width is 0.3 mm. The specific component layer is attached to the inside of the cylindrical body 1112 with an adhesive.

  The dirt of the game ball 11 can be removed on the surface of the specific component layer and the stepped portion where the strips overlap. The removed dirt accumulates in the stepped portion where the strips overlap. Further, the dirt of the game ball 11 can be further removed by the adsorbing power of the accumulated dirt. This is considered to be because the suction force between the dirts is stronger than the suction force between the game balls 11 and the dirt. Thereby, the dirt accumulated in the step portion can be removed from the game ball 11. Furthermore, as described above, the specific component layer biodegrades so that the inner surface of the pumping pipe gradually becomes rough with time, and a large amount of dirt adheres and the reduced adsorption power is restored. become able to.

  The dimensions of each part may be other dimensions as long as the flow of the game ball 11 is not hindered. For example, when the inner diameter of the cylindrical body 1112 is 11.5 mm and the thickness of the belt-shaped body is 50 μm, the inner diameter of the paper pipe 111 is 11.5−50 / 1000 × 2 = 11.4 mm at the overlapping portion of the belt-shaped body. It becomes. However, since the inner diameter of the paper pipe 111 in this case is larger than the diameter 11 mm of the game ball 11, the game ball 11 can flow.

  If the band of the specific component layer has at least a water vapor permeability lower than that of the cylinder 1112, the amount of moisture diffused out of the cylinder 1112 is reduced compared to the case where the specific component layer is not provided. As described above, it is preferable that the water vapor permeability at 40 ± 0.5 ° C. and 90 ± 2% RH is 1000 g / m 2 · 24 h or less. According to this, since the water vapor permeability of the specific component layer is not more than a predetermined value, it is possible to easily leave moisture of dirt (for example, sodium lactate) adhering to the game ball, and as a result, dirt can be easily adsorbed. .

  Further, the inner surface of the specific component layer has at least a dynamic friction coefficient and a static friction coefficient lower than those of the inner surface of the cylinder 1112, compared to the case where the specific component layer is not present on the inner surface of the cylinder 1112. Friction between the inner surface and the game ball 11 can be reduced. In general, a biodegradable material film has a lower coefficient of dynamic friction and a lower coefficient of static friction than paper such as cardboard of the cylinder 1112. As a result, it is possible to smooth the flow of the game ball of the lifting pipe 110.

The specific component layer is fixed to the cylinder 1112 by attaching a film of a band-like body with an adhesive. As an adhesive,
Those made of biodegradable resins such as polyester resins, polylactic acid resins, natural rubber resins, and polyvinyl alcohol are suitable. According to this, since the specific component layer formed in a film shape is adhered to the inner surface of the cylindrical body 1112 with the adhesive made of biodegradable resin, it is easy to process the specific component layer on the inner surface of the lifting pipe. .

[Second Embodiment]
In 1st Embodiment, the case where the edges of the adjacent strip | belt-shaped body (film) of the specific component layer of the conveyance pipe 110 were piled up was demonstrated. In the second embodiment, a case where there is a gap between adjacent strips of the specific component layer of the lifting pipe 110 will be described. The properties of the specific component layer are the same as those in the first embodiment.

  FIG. 12 is a diagram illustrating the structure of the paper pipe 111 of the lifting pipe 110 according to the second embodiment. With reference to FIG. 12A and FIG. 12B, as in the first embodiment, the paper pipe 111 is formed inside a cylindrical body 1112 serving as a base of the paper pipe 111 and the cylindrical body. And a specific component layer. A game ball 11 flows inside the paper pipe 111.

  The cylinder 1112 has a thickness of 1 mm and an inner diameter of 12 mm. The specific component layer is formed by spirally winding a strip having a width of 3 cm and a thickness of 30 μm. Further, a gap is made between adjacent strips. In the present embodiment, the width of the gap is 0.3 mm.

  The dirt of the game ball 11 can be removed at the surface of the specific component layer and the gap portion of the belt-like body. The removed dirt accumulates in the gap portion of the belt-like body. Further, the dirt of the game ball 11 can be further removed by the adsorbing power of the accumulated dirt. This is considered to be because the suction force between the dirts is stronger than the suction force between the game balls 11 and the dirt. Thereby, the dirt accumulated in the gap portion can be peeled off from the game ball 11. Furthermore, as described above, the specific component layer biodegrades so that the inner surface of the pumping pipe gradually becomes rough with time, and a large amount of dirt adheres and the reduced adsorption power is restored. become able to.

[Properties of specific component layer]
The properties of the specific component layer described in the first and second embodiments are preferably as follows.

  First, the lift pipe is preferably formed by forming a layer containing sodium lactate on the inner surface of the cylindrical body 1112 (including a specific component layer, which is also included in the biodegradable material layer). As shown in Table 1 and Table 2, the dirt adhering to the game ball contains a large amount of sodium lactate, so that the layer formed on the inner surface of the cylinder 1112 contains sodium lactate as the dirt component. As a result, the affinity between the two becomes relatively good, and dirt adhering to the game ball can be easily adsorbed.

  Sodium lactate is a composition of a specific component layer formed in a film shape. According to this, since the specific component layer is formed in a film shape, it is easy to process to form the specific component layer on the inner surface of the feed pipe, and the sodium lactate which is a dirt component is a composition of the film, so The affinity with the dirt adhering to the sphere is relatively improved, and the dirt can be easily adsorbed.

  Moreover, sodium lactate may be contained in the coating agent apply | coated to the film of a specific component layer. According to this, since the specific component layer is formed in a film shape, it is easy to process to form the specific component layer on the inner surface of the feed pipe, and the coating agent in which sodium lactate which is a dirt component is applied to the film Therefore, the affinity with the dirt adhering to the game ball is relatively improved, and the dirt can be easily adsorbed.

  The specific component layer or coating agent preferably contains 9.2 to 34.2% by weight, preferably 15.5 to 28.0% by weight of sodium lactate. This value is based on the value of sodium lactate (C, O, Na) contained in the foreign substances A to C shown in Table 1 (that is, the dirt attached to the game ball has moved to the lifting pipe). It is determined to contain sodium lactate of a weight percent close to the composition of this, and this makes the affinity between the specific component layer or coating agent and the dirt component relatively good, so that dirt adhering to the game ball is adsorbed. Can be easier.

  In addition to sodium lactate, the specific component layer or coating agent preferably contains 7.8 to 20.0% by weight, preferably 12.0 to 18.0% by weight of oil. This value is based on the oil content contained in the foreign matter A to C shown in Table 1 (that is, the soil adhering to the game ball has moved to the transport pipe), and the oil content in weight percent close to the composition of the soil component. As a result, the affinity between the specific component layer or coating agent and the dirt component becomes relatively good, so that the dirt attached to the game ball can be easily adsorbed.

  Moreover, it is preferable that the oil component contained in a specific component layer or a coating agent is mineral oil and / or sebum oil. This is because the oil contained in the foreign matter A to C shown in Table 1 (that is, the dirt attached to the game ball has moved to the lifting pipe) is mineral oil and / or sebum oil, Since the affinity between the specific component layer or coating agent containing mineral oil and / or sebum oil and the dirt component becomes relatively good, dirt attached to the game ball can be easily adsorbed. Here, the mineral oil is, for example, machine oil or grease oil, and the breakdown of the fatty acid of the sebum oil is, for example, 4.4% lauric acid, 7.8% myristic acid, 12.0% palmitoleic acid, 22.7 palmitic acid. %, Oleic acid 17.2%, stearic acid 5.7%.

  Furthermore, the specific component layer or coating agent may contain a fiber component in addition to sodium lactate. This is because the foreign substances A to C shown in Table 1 (that is, the dirt that has adhered to the game ball has moved to the lifting pipe) contain a fiber component that is a water-insoluble substance. Since the affinity between the agent and the dirt component becomes relatively good, dirt attached to the game ball can be easily adsorbed.

[Modification]
Next, a modification of the above-described embodiment will be described.

  In the above-described embodiment, the lifting pipe 110 is formed in one stage and can be replaced in one stage. However, the present invention is not limited to this, and the lifting pipe 110 may be formed in a plurality of stages, and each stage may be replaced individually. Further, the lifting pipes 120 and 130 have the same structure as that of the lifting pipe 110 and may be exchangeable. In this way, the plurality of stages of lifting pipes 110, 120, and 130 can be individually replaced.

  In the embodiment described above, the material of the pipe of the lifting pipe 110 is paper such as cardboard. However, the present invention is not limited to this, and the material of the pipe of the lifting pipe 110 may be other as long as it is a flexible material. For example, it may be a rubber, a flexible resin, or a fiber. In addition, although the polishing effect of the game ball due to the bending described above cannot be expected, a material having no flexibility, for example, a resin having little flexibility (for example, an acrylic resin, etc.) ), Metal, wood, ceramic and the like may be used.

  In the first embodiment described above, the overlapping width of the strips is reduced to 0.3 mm. In this case, the thickness of the most part of the specific component layer is the same as the thickness of the strip. For this reason, it is possible to prevent the specific component layer from becoming thick. However, the present invention is not limited to this, and the overlap width may be 1.5 cm with respect to a 3 cm wide strip. In this way, the thickness of the specific component layer is twice the thickness of the strip, so that the water vapor transmission rate can be about ½ times. Further, if the overlap width is 2 cm with respect to a 3 cm wide strip, the thickness of the specific component layer is three times the thickness of the strip, so that the water vapor permeability can be increased to about 1/3. it can. Similarly, if the overlapping width is set to Y with respect to the strip of width X, the thickness of the specific component layer is X / (XY) times the thickness of the strip, so that the water vapor permeability is about ( X−Y) / X times. In this way, even if the water vapor permeability of the strip is high, the water vapor permeability of the specific component layer can be lowered.

  In the above-described embodiment, the specific component layer of the paper pipe 111 of the lifting pipe 110 is formed by spirally winding a belt-like body. However, the present invention is not limited to this, and a belt-like body is wound perpendicularly to the longitudinal direction of the cylindrical body 1112 to form one step, and the edges of the adjacent ones of the steps are overlapped with each other, or adjacent to the steps. Each step may be formed with a gap.

  After the cylindrical body 1112 is formed into a cylindrical shape, when a strip-shaped body (film) is pasted on the inner surface, it is more efficient to form it by spirally winding it. However, in the case where the belt-like body is pasted in a developed state before the cylindrical body 1112 is formed into a cylindrical shape, the effort does not change whether it is wound spirally or wound perpendicularly to the longitudinal direction of the cylindrical body.

  Further, a strip-like body having a length in the longitudinal direction of the cylindrical body 1112 may be attached in parallel to the longitudinal direction. In this case, the entire circumference of the cylindrical body 1112 may be covered with a single belt-like body, or may be covered with a plurality of belt-like bodies. For example, one strip may be pasted every 90 degrees, and four strips may be pasted so as to cover the entire circumference.

  In these cases, the edges of adjacent strips may be overlapped, or a gap may be formed between adjacent strips. In this case, since the longitudinal direction of the overlapped portion and the gap is parallel to the longitudinal direction of the cylinder 1112, it is substantially parallel to the flow of the game ball, but the game ball is perpendicular to the longitudinal direction of the cylinder 1112. Since it also rotates in any direction, it is possible to remove the dirt of the game ball at the overlapping portion and the gap.

  Alternatively, a specific component layer may be formed by attaching a film piece of a biodegradable material having a predetermined shape (for example, a rectangle, an ellipse, or a polygon) to the inner surface of the cylindrical body 1112. For example, when pasting a 2 cm square rectangular film piece, since the circumferential length of the inner surface is 12 mm × π = about 37.7 mm, the circumferential direction can be covered with two pieces, The overlap width is (2 cm × 2-37.7) / 2 = 1. Further, a stepped portion where the film pieces overlap each other or a gap portion between the film pieces can be provided every 2 cm in the longitudinal direction.

  For this reason, it is possible to provide more stepped portions or gaps than when the specific component layer is formed of a 2 cm wide belt-like body, and more dirt is accumulated in the stepped portions or gaps. More dirt on the game ball can be removed by the adsorption force.

  In the embodiment described above, the inner surface of the specific component layer is assumed to be smooth. However, the present invention is not limited to this, and the inner surface of the specific component layer does not need to be smooth, and may be embossed, rough, or very short (a few μm) protrusion. It may be the surface which has. When it is not smooth, it is considered that the action of removing the dirt on the game ball becomes higher.

  In the embodiment described above, the second stage lifting pipe 110 is not directly connected to the discharge port of the main body of the lifting apparatus 100 but is connected via the first stage lifting pipe 120. It was made to be. However, the second stage lifting pipe 110 may be directly connected to the outlet of the main body of the lifting apparatus 100.

  In the embodiment described above, all the longitudinal direction of the cylinder 1112 of the paper pipe 111 of the feeding pipe 110 is formed of a flexible material, and is fixed in the longitudinal direction of the paper pipe 111. The fixed part (the part fixed by the open / close pipe stoppers 116 and 117) and the flexible part that is weakly fixed or not fixed (the part not fixed by the open / close pipe stoppers 116 and 117) are provided.

  However, the present invention is not limited to this, and a part of the longitudinal direction of the lifting pipe 110 is formed of a flexible material, and the other part is formed of a non-flexible material. While the portion formed of the material having no flexibility is fixed, the portion formed of the material having flexibility may be weakly fixed or may not be fixed.

  In the second embodiment described above, the specific component layer of the paper pipe 111 of the transport pipe 110 is one layer. However, a specific component layer may be further provided between the first layer and the cylindrical body 1112 so that the cylindrical body 1112 does not look into the gap between the strips of the specific component layer. In this way, the water vapor permeability of the paper pipe 111 can be further reduced.

  Even if the specific component layer is provided on the first layer so as to cover the gap, the same effect can be obtained. Further, even in the above-described embodiment, the gap is considerably narrower than the width of the band-like body (1/100 when the gap is 0.3 mm in the 3 cm-width band in the above example), and the area Therefore, the water vapor permeability of the paper pipe 111 is hardly adversely affected.

  In the above-described embodiment, the case where the invention is applied to the polishing apparatus for lifting the game ball has been described. However, as long as the game ball is transported, it is not limited to lifting, and it may be transported in the horizontal direction or transported in the downward direction.

  In the above-described embodiment, the invention has been described as an invention of a polishing apparatus provided with a lifting pipe (for example, a paper pipe 111) for removing the surface dirt of the game ball 11 flowing through the inside. However, the present invention is not limited to this, and can be understood as an invention of the gaming machine installation island 1 in which such a polishing apparatus is installed.

  In addition, it includes a lifting device 100, an upper tank, a lower tank, a cleaning device, and a transport pipe and a basket for connecting each, and the game ball 11 is collected from the pachinko gaming machine 10 and polished, It can be understood as an invention of a system for supplying to the pachinko gaming machine 10. It can also be understood as an invention of a lifting pipe (for example, a paper pipe 111).

In this embodiment, the biodegradable material layer is used as the specific component layer. However, the present invention is not limited thereto, and a resin, a resin containing nylon, a polyacrylonitrile resin, or a resin containing a polyethylene terephthalate resin may be used. Good.
Further, as the band-shaped body of the specific component layer, for example, Zeklon (registered trademark) (polyacrylonitrile (hereinafter referred to as “PAN”)-based resin Barex (registered trademark) formed into a sheet shape) 30 μm film, Hytron ( A registered trademark BX (PAN-based resin) 30 μm film, a Hytron (registered trademark) PG (polyethylene terephthalate (hereinafter referred to as “PET”)-based resin) 30 μm film, or the like can be used.

  The specific component layer may be another polymer resin film as long as the water vapor permeability at 40 ± 0.5 ° C. and 90 ± 2% RH is 1000 g / m 2 · 24 h or less. In general, the polymer resin film has a lower water vapor permeability than paper such as cardboard of the cylindrical body 1112. The water vapor permeability of the polymer resin in the inner layer of the lifting pipe 110 is below a predetermined value and is lower than that of the paper pipe 111. When such a polymer resin film is used, when the game ball is caused to flow through the inside of the transport pipe 110 by the lifting device, it is easy to leave the moisture of the game ball 11 (for example, lactate). Can do. As a result, the dirt can be removed without making it difficult to remove the dirt of the game ball.

  For example, polymer resin strips include PVDC (polyvinylidene chloride, VDC-MA copolymer (vinylidene chloride-methacrylic acid copolymer)), EVOH (EVA (ethylene-vinyl acetate copolymer) saponified product), OV. (PVDC-coated stretched PVA), MXD6 (metaxylidene adipamide), PAN, PVDC-coated ONy (biaxially stretched polyamide), PVDC-coated cellophane, PVDC-coated OPP (biaxially stretched polypropylene), ONy, CNy (unstretched polyamide) ), Cellophane, PVDC (VDC-VC copolymer (vinylidene chloride-vinyl chloride copolymer)), PET, PVC (polyvinyl chloride), OPP, HDPE (high density polyethylene), CPP (unstretched polypropylene), PC (polycarbonate) ), PS (polystyrene), LDPE (low density Plastic film for food packaging, such as ethylene) ( "Science and Industry", 80 (12), it may be a p602~608,2006).

These plastic films for food packaging have a thickness of 25 μm and a water vapor permeability of 1000 g / m 2 · 24 h or less. In a polymer resin film, it is said that the film thickness and water vapor permeability have an inversely proportional relationship. That is, if the film thickness is increased by X times, the water vapor permeability becomes 1 / X times.

  As long as the above-described criteria are satisfied, the polymer resin band is a single film (EVOH-based resin film, PVDC-based film, nylon-based film, etc.) or a coated film (PVDC-coated film, acrylic resin-based coating film, etc.). May be. Moreover, it is a vapor deposition film (aluminum vapor deposition film, alumina vapor deposition film, silica vapor deposition film, binary vapor deposition film), co-extrusion film (ONY-based co-extrusion film, EVOH co-extrusion OPP film, PVA-coated OPP film), and laminated film. May be.

  The water vapor permeability of the polymer resin strip is preferably quaternary or lower among the water vapor permeability classifications defined in “General Rules for Plastic Films for Food Packaging” of JIS Z1707, more preferably Grade 3 or less, Grade 2 or less, or Grade 1.

The classification of water vapor transmission rate of JIS Z1707 is 1 or less for grade 1, 2 to 1 and 5 for grade 3, 3 to 5 and 20 for grade 4, 4 to 20 for grade 4, The fifth grade is over 100, and the unit is g / m 2 · 24 h. Each grade of plastic film for food packaging can be used properly depending on the application and cost, so it can be said that the classification has a critical significance.

  The water vapor transmission rate is defined in JIS K7129 “Plastic-Film and Sheet—How to Obtain Water Vapor Transmission Rate (Equipment Measurement Method)” or JIS Z0208 “Moisture-permeable test method for moisture-proof packaging materials (cup method)”. Can be determined by testing.

  In addition, as long as the belt-like body of the polymer resin layer has at least an oxygen gas permeability lower than that of the cylinder body 1112, oxygen flowing from the outside of the cylinder body 1112, compared to the case without the polymer resin layer. The amount of can be reduced.

The polymer resin strip may be another polymer resin film as long as the oxygen gas permeability at 23 ± 0.5 ° C. and 50 ± 2% RH is 5000 fmol / m 2 · s · Pa or less. . In general, the polymer resin film has lower oxygen gas permeability than paper such as cardboard of the cylindrical body 1112. The oxygen gas permeability of the polymer resin in the inner layer of the lifting pipe 110 is below a predetermined value and is lower than that of the paper pipe 111. If such a polymer resin film is used, inflow of oxygen into the inside of the lifting pipe 110 can be suppressed when a game ball is passed through the inside of the lifting pipe 110 by the lifting device. As a result, it is possible to prevent the occurrence of contamination due to oxidation of each part of the lifting device 100. Moreover, generation | occurrence | production of the oxidation odor by oxidation of dirt can be suppressed.

For example, among the polymer resins having low water vapor permeability described above, PVDC, EVOH, OV, MXD6, PAN, PVDC coat ONy, PVDC coat cellophane, PVDC coat OPP, ONy, CNy, cellophane, PVDC, PET, PVC For example, at 25 μm, the oxygen gas permeability is 5000 fmol / m 2 · s · Pa or less. In a polymer resin film, it is said that the film thickness and oxygen gas permeability have an inversely proportional relationship. That is, if the film thickness is increased by X times, the oxygen gas permeability becomes 1 / X times.

  The oxygen gas permeability of the polymer resin strip is preferably 4 or less, more preferably among the oxygen gas permeability class categories defined in “General Rules for Plastic Films for Food Packaging” of JIS Z1707. Is grade 3 or less, grade 2 or less, or grade 1.

The class classification of oxygen gas permeability of JIS Z1707 is 5 for the first grade, 5 for the second grade, 25 for less than the third grade, 25 for greater than 25 for the third grade, 100 for less than the fourth grade, 500 for less than the 500th grade The fifth grade is over 500, and the unit is fmol / m 2 · s · Pa. Each grade of plastic film for food packaging can be used properly depending on the application and cost, so it can be said that the classification has a critical significance.

  Oxygen gas permeability is measured according to JIS K7126-1 “Plastics—Film and Sheet—Gas Permeability Test Method—Part 1: Differential Pressure Method” or JIS K7126-2 “Plastic—Film and Sheet—Gas Permeability Test Method— It can be obtained by the test prescribed in “Part 2: Isobaric method”.

  Further, if the inner surface of the polymer resin layer has at least a kinetic friction coefficient and a static friction coefficient lower than those of the inner surface of the cylindrical body 1112, compared to the case where the inner surface of the cylindrical body 1112 does not have the polymer resin layer, the lifting pipe Friction between the inner surface of 110 and the game ball 11 can be reduced. In general, the polymer resin film has a lower coefficient of dynamic friction and a lower coefficient of static friction than paper such as cardboard of the cylinder 1112. As a result, it is possible to smooth the flow of the game ball of the lifting pipe 110.

  The dynamic friction coefficient and the static friction coefficient can be determined by a test defined in “Plastic-film and sheet-friction coefficient test method” of JIS K7125.

  Moreover, the cylinder 1112 and the polymer resin layer are fixed by being attached with an adhesive. As the adhesive, it is possible to use an adhesive that can be applied to both the plastic of the polymer resin layer and the paper of the cylindrical body 1112 such as an epoxy adhesive, an acrylic adhesive, and a double-sided adhesive tape.

  Moreover, if the gas barrier adhesive for films is used, the gas barrier properties of water vapor and oxygen gas of the polymer resin layer can be improved.
