JPH0880969A - Package for catgut for racket - Google Patents

Abstract

PURPOSE: To enable continuously drawing out catgut without allowing it to tangle by providing a slit or yielding line in a ring on the surface of the reverse side of a package that shuts in catgut placed in an unbound state inside a hollow. CONSTITUTION: A package prior to unsealing is provided on the reverse side 2 with a yielding line 4 in a circle that forms a slit for drawing out catgut 5 and at the position where this yielding line 4 forms an overlap a yielding line 4 for forming a cut-out hole. To unseal this package and draw out the catgut 5, the reverse side 2 of the package is torn along the yielding line 4, and then an opening and a slit 6 for picking out the catgut 5 are formed. The catgut 5 picked up through the opening is drawn out through the slit 6. When extracted, the catgut 5, placed inside a ring-shaped hollow space 3, comes loose from a coil progressively and in an orderly manner by being passed through the slit 6. When the catgut 5 is drawn out to a specified length as well, the catgut 5 in the package hardly shows a tendency to entanglement.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a racket gut package.

[0002]

2. Description of the Related Art Usually, a gut for a racket is put in a vinyl bag in a state of being wound up in a ring shape, or put in a plastic case having a recessed part in the shape of a gut and attached from the back side. It was sealed in the case by the mount. In either case, the gut is bound with a binding band or the like so as to maintain the rolled shape, and it is necessary to cut the binding band after the package is cut and the gut is taken out.

[0003]

The gut to be bound with a binding band is costly at the manufacturing stage and requires labor for cutting the binding band when it is used. The binding band is in close contact with the gut, and there is a risk of damaging the gut body if it is cut inadvertently.
Stress concentrates and the strength decreases. An even bigger problem is the work of stretching the gut. Gut
Due to its nature, the strength tends to decrease when bent or kinked, and it was a very troublesome work to stretch a gut having a ring-shaped curl and having a total length of 11 m so that it would not get tangled. The present invention is intended to allow the gut to be continuously pulled out of the package without being entangled.

[0004]

A gut housed in a ring-shaped or 8-shaped ring-shaped recess formed in the front package surface without being bound is closed by a back package surface that covers the recess, and the back package is closed. A slit is formed on the surface at a position along the ring-shaped or 8-shaped ring-shaped recess, or a weakening line is provided so that the slit can be formed.

[0005]

In the package of the present invention, when the vicinity of the end of the gut is held by a finger and pulled out from the package, the gut is sequentially pulled out while receiving resistance at the slit portion. Usually, when pulling and unwinding a coiled wire from the end, there is only a little tangling or catching, and the pulling force concentrates on that part, so the wound shape may be deformed. , The way the wires overlap is changed. This had a vicious circle of further increasing the entanglement and entanglement. The gut of this package has a concave shape so that the winding shape does not change.
The force applied to the coiled gut when pulling out the gut is in the direction of the slit, and the slit part prevents the gut from coming out in a entangled state at a time, so there is some entanglement in the coiled gut. Even if there is, you can pull out the gut without getting tangled. In addition, since the pulled out gut does not come out naturally, it is convenient when cutting a fixed length.

[0006] The applicant of the present application has previously proposed a gut-type 8-shaped winding storage as a gut packaging method. In this case, the present package can be used more effectively. When pulling out the gut in this package, it is necessary to search for the end of the gut.
At the cross-shaped position, it is clear that the guts cross in the order in which the guts are rolled up, and the uppermost and lowermost parts of the crossed parts are near the gut ends. For this reason, it is possible to easily hold the end of the gut by making a hole for pulling out the gut near the intersection of the figure 8 and pinching and pulling out the uppermost cross part.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, specific embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows an unopened package of the present invention. The backside package 2 is provided with a weakening line 4 which is a slit for pulling out the gut in a circular shape, and the weakening line 4 for forming a cutout hole is provided at a position overlapping with the weakening line 4. FIG. 2 shows a state in which the package of this example is opened and the gut is pulled out. An opening for picking out the gut and a slit 6 are formed by breaking the weakening line 4 of the backside package 2, and the gut picked out from the opening is pulled out through the slit 6. .

FIG. 3 is a sectional view of the package. The front package 1 made of resin and the back package 2 made of cardboard or resin are adhered to each other at the contact surface excluding the ring-shaped recess 3. The gut 5 stored in the space of the ring-shaped recess 3 passes through the slit 6 when pulled out,
It is taken out in the order that it is rolled up in order. Further, even when the gut is pulled out by a predetermined length, the remaining gut is contained in the package, and therefore it is very difficult to get tangled.

In FIG. 4, the back side package 2 and the front side package 1 which are formed with a hollow hole slightly larger than the central cylindrical protruding portion 8 forming the ring-shaped recess 3 are joined to form the inner edge 9 of the hollow hole and the cylinder. The gap formed by the upper edge portion 8 of the projecting portion is provided with the slit 6 for pulling out the gut.
Is an example. The width of the slit 6 in this example can be made wider than that in the case of using the weakening line. If the width of the slit is too wide, a plurality of guts may come out in a tangled state even if the gut in the rolled state has some catch. When actually applied, it seems that the width of the slit is desirably about 1 cm or less.

FIG. 5 is a cross-sectional view of the example of FIG. 4, but the hollow hole of the back side package is formed by cutting the weakening line 4. In this case, unlike the example of FIG. 1, the cut-out portions are separated because they are not bonded at the central cylindrical protruding portion 8.

FIG. 6 shows the package of the example of FIG.
This is an example in which the hollowed-out hole portion of the back side package is hermetically sealed with the sealing material 7. The slit portion 6 is exposed by peeling off the sealing material 7 from the package.

FIG. 7 shows an example in which the weakening line 4 is formed on the sealing material 7 shown in FIG. In the case of this example, the slits are easily formed by using a material that is easily broken.

FIG. 8 shows a gut holding groove 10 formed at the end of the gut on a cylindrical protrusion 8 in the center of the front side package.
It is an example fixed to. In the case of a gut packaged in a coil, the gut can be taken out smoothly by pulling it out from the end, but by holding the gut end in a predetermined place as shown in this figure, the gut can be taken out easily. It will be easier. A holding portion for facilitating removal of the gut end portion as in this example may be provided on the outer frame portion of the package.

FIGS. 9 to 11 show the package of the present invention for accommodating the gut which is wound in the shape of FIG. In FIG. 9, a weakening line 4 is formed on the backside package 2, and the separated weakening line becomes a slit 6. The hatched portion in FIG. 9 may be cut out or may be formed so as to be bent outward because it may be caught when the gut is pulled out. The weakening line 4 of the package outer frame portion is a cutout portion for picking out the gut end portion, and the gut end portion is located under the same portion.

FIG. 10 shows a cut-out hole weakening line 4 for picking up the end of the gut, provided between two substantially circular weakening lines 4 to be slits, and this part is cut out. . Since the intersections of the guts that are wound in the shape of a figure 8 are laminated in the order in which they are wound, the gut ends can be easily held by picking up the top of the intersections. Further, since the cut-out portion in the center of the package corresponds to the hatched portion shown in FIG. 9, when the gut is pulled out, it is not caught at the same portion.

FIG. 11 shows an example in which a slit is formed by the upper edge portions of two cylindrical protrusions 8 forming the ring-shaped recess 3 of the front side package 1 and the inner edge portion 9 of the hollowed hole of the back side package. The two hollow holes on the back side of the package are connected like a pair of spectacles, and since the central part overlaps the crossing position of the gut, it is possible to pick up the gut from the same part. The hollow hole in this example is
It is cut out along the line of weakness, or as in the example of FIG. 6, the hole is pre-cut out and the sealing material is covered, or as in the example of FIG. ,
By cutting the weakening line provided on the sealing material surface, a hollow hole is formed on the back surface of the package.

FIG. 12 shows a double-sided slit forming weakening line 4 provided on the back side package 2.
The distance between the two weakening lines is the width of the slit 6. This figure shows
It shows an example of storing the gut in a ring shape,
It can also be used when it is stored in a figure eight shape. Further, in this example, the slit is formed by winding the weakened line portion in a band shape, but a method of forming the slit on the back side of the package as in this example and covering the slit portion with the sealing material is also possible. is there.

[0018]

As described above, the gut drawn out from this package can be smoothly taken out while being arranged in the slit portion, so that the pulling up work can be speedily performed without being troubled by the entanglement and entanglement of the gut. The method of tensioning the gut is called double tension, and a method of cutting a gut with a total length of 11 m or more into two pieces with a predetermined length and stretching the racket vertically and horizontally is sometimes used.
This package is very convenient in this case because it is not necessary to stretch all the guts at a time as in the conventional case and the guts can be extracted by a predetermined length. Conventionally, a package in which a gut is enclosed between a vinyl chloride molded sheet and a cardboard has been widely used, but the package of the present invention can also be manufactured from the same inexpensive material. This package can be applied not only to the conventional package in which the gut is stored in a ring shape, but also to a package in which the gut is stored. In this case, since the gut end can be easily picked up, it is more effective. It can be said that there is.
