Description

[Detailed Description of the Invention] The present invention involves winding long objects such as strings, nets, tubes, ropes, sheets, etc. without core and wrapping them in a flexible bag. Alternatively, by storing it in a support frame made of a material that is foldable and flexible and rigid in other directions, the required amount can be pulled out and cut in sequence from one end and used, even if the internal capacity decreases. This invention relates to a wound long article with a support frame that maintains a substantially constant external shape and can be pulled out without getting tangled to the end, is easy to handle and manufacture, and a method for manufacturing the same.

Conventionally, long objects such as strings and tapes have been wound up and used by pulling out the required amount from one end. When it is wound around a core, it can be pulled out to prevent the winding from collapsing and becoming entangled, but it requires force to rotate the core, and those with a means to easily rotate the core are large and require installation space. Difficult to handle. In order to prevent coreless winding, the winding angle is generally changed continuously, so-called traverse winding, and the winding is pulled out from the center. In this method, in the initial stage of use, the external shape is kept constant due to the self-shape retention property due to the thickness of the wound long object, so roll collapse does not actually pose much of a problem. However, as the amount decreases, troubles often occur, such as the external shape breaking down and entangling each other internally, or the unwinding resistance decreasing and a large amount being unwound while remaining tangled. Something happened.

The present invention provides a long article with a support frame that can be pulled out to the end without getting tangled using a simple support frame with a cutting blade, and is equipped with a cutting means that can be cut with one hand after pulling out the required amount, and a method for manufacturing the same. be.

The present invention will be explained in detail below.

In the present invention, a long object is an endless object such as a string, a tubular net, a tubular plastic film, a thread, a tape, a ribbon, a plastic film, a wire, a rope, etc., and is wound without a core and is pulled sequentially from one end. It is something that can be produced.

The material for the support frame in the present invention is one-sided corrugated cardboard, paper, paperboard, plastic sheet, or a laminate thereof, and must be flexible enough to be rolled or folded on one side, and easily rolled or folded on the other side. Requires rigidity to prevent bending. Such a support frame can be obtained by simply cutting a material for the support frame into a substantially rectangular shape, wrapping a long object containing the contents in a winding manner, and gluing both ends to obtain a cylindrical container having self-shape retention properties. In this case, due to the characteristics of the material, the support frame material can be rolled up only in one direction, and adhesive is applied to both ends in this direction. By gluing the inner surface of this support frame and the outer surface of the bag for the long items to be loaded at at least one place, the outer shape of the rolled long items will not collapse even if they are handled roughly and the number of long items decreases. The roll will not collapse until the end.

Furthermore, since the long contents themselves are contained in the bag, no bottom material is required. Therefore, manufacturing is extremely easy; simply align the rigidity direction of the support frame material cut into rectangular shapes with the depth direction of the wound long object, apply adhesive as appropriate, and then create the support frame. It can be manufactured by simply gluing both ends of the material for use and the bag.

When wrapping the supporting frame material, apply adhesive to both ends and overlap the ends to obtain a cylindrical container that is adhered to the outer surface of the bag. Further, the same effect can be obtained even if the two are butted but not overlapped. The adhesive may be applied to only one end of the support frame material and the materials may be overlapped, or the adhesive may be applied to any part of the support frame material.

The cutting blade is sharp enough to easily cut long objects,
Moreover, it is safe and poses no risk of injury to hands or fingers. To do this, a narrow, tapered guide groove that is difficult for the fingertip to enter is bored at the end of the support frame on the side where the outlet for elongated objects is located, and the cutting blade is fixed at the back of the groove. In this way, there is no risk of fingers touching the blade, which is safe, and the long object is reliably guided to the cutting blade.

Bags for storing long objects are those that come in close contact with long objects,
It is desirable to have an opening in the center that serves as an outlet for elongated objects. The opening should be large enough so that it does not create resistance when pulling out long objects. For this purpose, it is desirable to use so-called shrink packaging, in which a plastic film is stretched, a long length of the product is wrapped with a film that does not fix the stretching, the film is heated to shrink, and the contents are tightly packaged. According to this method, the elongated object is closely attached, and a suitable opening is left in the center of both ends, and this opening coincides with the outlet of the elongated object.

A long object can be cut by simply inserting it into the guide groove and pulling it to apply tension. At this time, if a long object is additionally pulled out, sufficient resistance cannot be obtained, so it becomes necessary to hold it down by hand. In order to easily cut with one hand, it is desirable to have something that provides some resistance during cutting. For example, the guide groove may be made deep and narrow, or a guide hole may be provided in the support frame at an appropriate distance from the guide groove with the cutting blade, through which the long object can be pulled out with almost no resistance.

In this case, the elongated object is once pulled out from the guide hole to the outside of the support frame, and when cutting, the elongated object is bent at a substantially right angle at the upper end of the support frame and resistance generated when moving upward can prevent additional drawing out. Alternatively, a hole through which a long object passes may be provided at any part of the outer periphery of the opening of the bag instead of the support frame, or the opening of the bag may be covered with a coating having guide holes of an appropriate size. The resistance means provided in the bag does not adversely affect the cutting effect even if the number of long objects decreases because the support frame is firm.

Hereinafter, the present invention will be described in detail by way of examples with reference to the drawings.

FIG. 1 is a sectional view of one embodiment of the present invention, and FIG. 2 is a plan view showing the state immediately before completion. Reference numeral 1 denotes a supporting frame material made of single-sided corrugated paper, which is flexible in the horizontal direction in this figure but rigid in the vertical direction, and is bonded into a cylindrical shape to form a supporting frame.

Reference numeral 2 denotes a long piece, and in this example, a seamless tube of high-density polyethylene with a thickness of about 8 μm and a circumference of 50 cm obtained by inflation processing was pulled out. 3 is a bag for wrapping the long object 2, and has an opening 4 at one end. In this example, so-called shrink packaging was used. As a result, openings remained at both ends, but this did not pose any practical problems.

FIG. 1 shows a state in which the charged elongated article 5 obtained in this manner is fixed to a support frame via an adhesive 6. Reference numeral 7 indicates adhesive bonding parts provided at both ends of the support frame material, and may be provided only at one end.

Reference numeral 8 denotes an adhesive bonding area which may be provided on other parts of the support frame material if necessary, to more reliably fix the bag 3 to the inner surface of the support frame. 9 is a guide hole, provided at one end of the support frame,
A notch 15 was bored in the upper part.

Reference numeral 10 denotes a guide groove, which is slightly separated from the guide hole 9, and has a cutting blade 11 fixed therein. The notch 15 facilitates guiding the long object to the guide groove 10 during cutting, and improves the cutting effect by allowing the long object to contact the cutting blade at a substantially right angle.

In use, the tip of the elongated object 2 is pulled out from the guide hole 9, the drawn out tip is pinched and pulled out as much as necessary, and simply placed in the guide groove, and the object inevitably comes into contact with the cutting blade and is cut. Therefore, the length of the portion drawn out from the guide hole after cutting is the passage distance between the guide hole and the cutting blade.

According to the present invention, no matter how small the length of the long object is, the outer shape is maintained due to the rigidity in the depth direction of the support frame material,
Even if an external force is applied, it does not affect the inside, so it does not get tangled, and it can be manufactured very easily by simply rolling it.

FIG. 3 shows a perspective view of another embodiment, and FIG. 4 shows a sectional view thereof. In this case, the support frame element JA1 is paperboard,
The two fold lines 12 and 13 provide flexibility in the radial direction and divide the cylindrical portion of the support frame into approximately two equal parts. Therefore, although the support frame material itself has rigidity in all directions, it becomes flat due to the fold line 12.13, and when contents are inserted, it swells depending on the amount, and it constantly tries to return to its flat state, compressing the contents. It has the ability to recover. Reference numeral 2 denotes a long piece, and in this example, a string made of stretched polypropylene film wound into a single ball was used. 3 is a bag having an opening 4, and is fixed to the support frame 1 with adhesive. Reference numeral 7 denotes a portion of the support frame 1 to which an adhesive is attached, and the adhesive is attached at this portion to form a cylindrical shape. Reference numeral 9 denotes a guide hole, which was provided at one end of the support frame. Reference numeral 11 denotes a cutting blade fixed at the back of the guide groove 10, separated from the guide hole 9, preferably on the opposite side. These parts are on the side of the bag 3 where the opening 4 is located. The long object 2 pulled out from the guide hole 9 is passed from the outside of the support frame to the guide groove on the other side, inserted into the guide groove 10, and cut by a cutting blade 11 provided inside the guide groove.

5 to 7 are cross-sectional views of other embodiments. Fifth

was applied, and a tape piece 16 to which no adhesive was applied was attached to the center. As a result, as shown in FIG. 6, which is a cross-sectional view taken along the line vi-vi in FIG. Contact with the cutting blade. In this embodiment, the support frame 1 used was shorter than the long material to be charged and wound.

In the case shown in FIG. 7, a membrane 18 covering the opening 4 of the bag 3 is attached. A guide hole 9 is drilled at the outlet of the wound long object in the center of the coating.
It passes through and reaches the cutting blade 11. Even if the number of long objects decreases, the contents will not get entangled and the cutting effect will not be adversely affected. In this embodiment, the bottom end of the support frame 1 is wavy, but the bottom end does not need to be straight.
