Description

The present invention relates to removing dirt such as mud adhering to a golf ball. More specifically, the present invention is a nonwoven fabric in which dirt such as mud adhering to a golf ball is dampened with water during golf play, taking advantage of the water absorbency of the nonwoven fabric and the heat processability and waterproofness of the thermoplastic resin. It can be easily carried without wiping or wetting clothes.

Traditionally, in a general golf course, a caddy was attached to each set to play, and the caddy wiped the ball mark repaired on the grass and the mud of the ball, etc. It became self-serving without a caddy. As a result, it was not possible for the player to repair green grass damaged by the ball mark or wipe mud on the ball. However, the green turf damaged by the ball mark is still unrepaired, and in order to wipe the mud of the ball, go to the passenger cart to get towels, or wipe the mud with pants or shirts. Can now be seen.

Problems to be solved by the invention

  The present inventor previously obtained Japanese Patent No. 5590361. In the previous invention, when manufacturing a portable golf ball cleaner, a sheet-like nonwoven fabric formed by laminating a waterproof thermoplastic resin was used. There was a concern that it would require manual work to accurately align the other sheet-like material on one side with each other back to back, and that it would take time to reverse the bonded bag body. Therefore, the present inventors have invented a method for manufacturing a portable golf ball cleaner that can eliminate these problems.

Means for solving the problem

  The present invention relates to the sheet-shaped nonwoven fabric having a fold-like portion formed by cutting a part of a sheet-shaped nonwoven fabric formed by laminating a waterproof thermoplastic resin on one side.

  An embodiment according to the present invention will be described below with reference to FIGS. The golf ball wiping bag of the present invention is different from the previous invention (Patent No. 5590361) in that a sheet-like nonwoven fabric formed by laminating a waterproof thermoplastic resin on one side is cut into a pleated shape. The sheet-shaped nonwoven fabric is punched in a long-side direction so that the waterproof thermoplastic resin is on the outside, or is folded into four outer folds and stacked in four layers. A golf ball wiping bag characterized by forming a bag body including the pleated portion by welding a predetermined width to an edge portion, and requires manual work to be reversed through an opening of a conventional bag body However, the manufacturing process is simplified, and the manufacturing itself is facilitated.

  As shown in FIGS. 1 to 8, the nonwoven fabric bag 1 of this embodiment has a sheet-like nonwoven fabric 1c formed by bonding a waterproof thermoplastic resin 1b on one side, a right side surface portion 1f, a left side surface portion 1g and the right side. It consists of four parts, a mud wiper fold part 1h and a left mud wiper fold part 1e, and the left and right mud wiper fold parts and the left and right side parts are crease-shaped parts that become openings when molded respectively. And the fold scheduled portion 1d on the side surface.

  The thermoplastic resin 1b of the sheet-like nonwoven fabric 1c is placed outside, and the left mud wiper fold 1e, the left side 1g, the right side 1f, and the right mud fold 1h are made in the order of the left side as shown in FIG. 4 layers, sandwiching left and right mud wiper folds between the left and right side parts, and water retention that includes left and right mud wiper folds to be welded after overlapping as shown in FIG. The characteristic nonwoven fabric bag 1 is completed.

  As shown in FIG. 3, the outer four folds are made with the thermoplastic resin 1b of the sheet-like nonwoven fabric 1c on the outside, and from the left, the left side surface portion 1g, the left mud wiping fold portion 1e, the right mud wiping fold portion 1h, the right side surface portion 1f. Is layered in four layers, the left and right mud wiper folds are sandwiched between the left and right side parts, and the water retention is included in the left and right mud wiper folds that are welded after overlapping as shown in FIG. The non-woven bag 1 shown in FIG.

  Examples of the material of the nonwoven fabric 1c in which the outer surface of the nonwoven fabric bag 1 having an opening 1a at one end is coated with a highly waterproof thermoplastic resin 1b include rayon, pulp, cotton, wool, and the like. Further, polyethylene, polypropylene, polyester, polyethylene terephthalate and the like are generally used as the thermoplastic material, and may be used alone or mixed depending on the application. In order to achieve the purpose of the nonwoven fabric bag 1 of the present invention, the material of the nonwoven fabric 1c is preferably a single material of a thermoplastic material having good water retention or a non-woven fabric 1c having both water retention and thermoplasticity by mixing.

The nonwoven fabric used by mixing may be produced by adding polyethylene or polyethylene terephthalate to pulp or the like, and in addition, the nonwoven fabric 1c having a water holding capacity of 500 cc / m ² or more is preferable. The thickness of the nonwoven fabric 1c to be used for non-woven fabric bag 1 of the present invention is usually ^30g / ^{m 2 ~150g} / m 2 and it has less water retention capacity in the case of 30 g / ^{m 2} or less, in the case of 150 g / ^{m 2} or more Although there is a water retention amount, processing is difficult. ^Preferably, it is selected in the range of ^{50g / m 2 ~100g / m 2} . Moreover, the function which the nonwoven fabric 1c has is supplemented by bonding the thermoplastic resin 1b to the nonwoven fabric 1c. By this, it becomes invention of the nonwoven fabric bag 1 which has water retention, waterproofness, a softness | flexibility, and intensity | strength. As a material of the thermoplastic resin 1b to be bonded to the nonwoven fabric 1c, a film of a general-purpose thermoplastic resin 1b such as high-density polyethylene, low-density polyethylene, linear low-density polyethylene, polypropylene, and polyvinyl chloride is used. A film of thermoplastic resin 1b such as nylon, polyester, polyvinyl alcohol or the like can also be used.

  These films may have a single layer structure or a laminated structure of two or more layers. The thickness of the thermoplastic resin 1b to be used is usually 10 μ to 80 μ, but when it is 10 μ or less, the welding temperature, impact resistance, tear strength, etc. are lowered, and when it is 80 μ or more, the welding temperature is increased and the sealing property is increased. Becomes worse. Furthermore, the rigidity becomes stronger, and the efficiency is lowered when processing. Further, when removing the dirt from the golf ball 3, the operation is such that the non-woven bag 1 containing the golf ball 3 is squeezed from the top together with the bag. However, as the thickness of the thermoplastic resin 1b increases, the flexibility increases. Drops and detergency. Preferably, it is selected in the range of 20 μ to 50 μ. That is, by having the bag-like portion illustrated in FIG. 1, the shape is simplified, the shape can be carried, and water retention is improved.

  First, when manufacturing, the thermoplastic resin 1b was bonded to one side of the sheet-like nonwoven fabric 1c. By combining the nonwoven fabric 1c with high water retention and the thermoplastic resin 1b with high waterproofness, welding becomes possible and both waterproof properties are obtained. In the sheet in which the thermoplastic resin 1b and the nonwoven fabric 1c are integrated, the portion of the thermoplastic resin 1b can be welded. In addition, water leakage from the inside of the bag and evaporation of water, water retention, and external impact strength can be improved.

  The opening 1a, which is an inlet for the golf ball 3 processed into a bag shape as the non-woven bag 1, is usually 70 mm to 140 mm because the diameter of the golf ball 3 is 42.67 mm. It is not easy to put in, and if it is 140 mm or more, it will be in the way when carrying. Therefore, it is preferably in the range of 75 mm to 100 mm. The depth of the nonwoven fabric bag 1 is usually 50 mm to 150 mm, but if it is 50 mm or less, the golf ball 3 does not fit in the bag, and if it is 150 mm or more, it is difficult to take out. Therefore, Preferably, it is the range of 60 mm-110 mm. Further, the width is usually from 75 mm to 110 mm, but when used, the welded portion 1k is located outside the opening 1a, and thus is preferably in the range of 85 mm to 100 mm. The width of the welded portion 1k when heat-welding in a bag shape is usually 1 mm to 7 mm, but if it is 1 mm or less, it is welded from the thickness of four sheets of nonwoven fabric 1c as shown in FIG. Anxiety arises. In the case of 7 mm or more, the inside of the opening 1a becomes narrow. Therefore, preferably, the width of the welded portion 1k is preferably 2 mm to 5 mm in order to improve the opening property when the golf ball 2 in the range of 2 mm to 5 mm is inserted.

The separation portion 1j of the opening connected to the fold portion is punched in parallel with the fold portion 1d forming the opening portion 1a and the folding portion 1d of the side surface portion, and becomes the uppermost portion of the fold 1i. A range of is desirable. Further, the left and right mud wiping folds are connected to the bottom part below the separation part 1j of the opening connected to the left and right folds. Further, the width of the fold 1i is usually 2 mm to 10 mm, but processing is difficult if it is 2 mm or less, and if it is 10 mm or more, the increasing rate of the wiping area is low, and the wiping function is lowered, preferably 2 mm to 6 mm. The length of the fold 1i is normally 20 mm to 50 mm, but if it is 20 mm or less, the wiping function is lowered, and if it is 50 mm or more, which is about half the width of the nonwoven fabric bag 1, it cannot be manufactured. Therefore, it is preferably in the range of 20 mm to 45 mm. As for the cross section of the fold 1i, the non-woven fabric 1c is welded to the thermoplastic resin 1b in a state of a plate kamaboko, so that the wiping area is three-dimensionally increased. Further, since the mud wiping fold 1e absorbs water and swells and is swollen together with the golf ball 2 from the outside of the non-woven bag 1, it is effective in removing dirt such as mud adhering to the golf ball 3. Also in this case, the nonwoven fabric 1c is welded to the thermoplastic resin 1b, so that it is not easily peeled off. Even if the width of the fold 1i is narrowed and elongated, it is difficult to cut easily. As a result, the ball can be wiped with one hand.
Further, the opening portion 1a into which the golf ball 3 is thrown is a folded portion of a connection between the fold portion and the side surface portion, and when the nonwoven fabric bag 1 is placed horizontally by the separation portion 1j of the opening portion connected to the fold portion, Prevents dripping of water retained in the water. The separating portion 1j of the opening connected to the fold portion is punched in parallel with the fold portion forming the opening portion 1a and the planned folding portion 1d of the side surface portion, and becomes the uppermost portion of the fold 1i. Furthermore, the position for the construction is preferably in the range of 10 mm to 20 mm from the opening 1a.
The use of the non-woven bag 1 is when the golf ball 3 reaches the green, after marking the position of the golf ball 3 with a ball marker or the like. At this time, the ball fork attached on the green is also restored using the green fork 2. Therefore, the function of the non-woven bag 1 is further exhibited by engaging the non-woven bag 1 and the green fork 2.
However, there are more opportunities to wipe the ball, depending on local rules.
