Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous tube for a bag which can be used as a bag by pulling out a continuous tube for a bag folded and wound corelessly to an arbitrary length, cutting it, and tying one end. More specifically, the present invention relates to a distribution set for a continuous tube for a bag, which can be manufactured by simply winding it without using a container such as a box or a bag, and can save the trouble of providing a stenosis extraction hole. .

2. Description of the Related Art Regarding the technique of winding and storing a continuous tube and unwinding it from the end to use it as a bag having an arbitrary length, JP-A-59-163158 and JP-A-59-1.
It is disclosed in Japanese Patent Publication No. 75033. That is, the wound continuous tube is housed in a container, and the end of the wound tube is pulled out through the narrowed extraction hole provided in the distribution container from the center to the required length, and then an appropriate length is drawn out from the withdrawal port. It is used as a bag by cutting with a cutting means provided at a distant site and ligating one end.

Further, the continuous tube becomes a nodule and is unintentionally pulled out in a large amount, or when the portion to be cut is inserted into the slit for cutting and abutted against the blade edge and pulled, the continuous tube is further pulled out. Therefore, in order to improve the disadvantage that the continuous tube does not contact the cutting edge in a tensioned state and deteriorates the sharpness, the narrowed extraction hole is used to make the extraction hole as small as possible without affecting the extraction of the continuous tube. I was pulling out.

[0004]

However, many containers of wound continuous tubes are box-shaped and tend to be bulky. There is also a method in which a continuous tube wound between two rigid plates connected to each other is inserted, and the continuous tube is continuously drawn out from a constriction extraction hole provided in a part of the rigid plate. This method also requires a cylindrical container,
Since the continuous tube is stored in the central portion, the central portion swells and both ends remain as voids, which is a waste of space for the distribution container. Therefore, the result is the use of a container that is bulkier than the amount of the content continuous tube, which is inconvenient to carry.

Further, since the narrowed-out hole is a small hole, it is difficult to pull out the winding start end portion from the wound tube after being housed in the container, which makes the housing work troublesome. Therefore, it is a portable tube distribution set that is more convenient to carry and that does not need to be stored in a bag or box using a cheap material, does not require a narrowing extraction hole, and can be manufactured by a simpler manufacturing process. Was required.

The present invention has as its object to solve the above-mentioned problems, and its constitution is to fold a tubular plastic film into a narrow width, press flatly a continuous tube for a bag wound corelessly, The flat surface has a smooth surface, spiral parts at opposite ends, and folded parts at opposite ends, and a winding start end is drawn out from the center of the spiral part longer than one folded part. Then, the flat roll is integrally wound around the rigid plate by the strip-shaped sheet with the winding start end projecting, and one end of the rigid plate projects from the folding part of the flat roll, and the protruding part of the finger A slit that does not enter is carved, and a cutting blade is provided at the bottom of the slit.

The continuous tube of the present invention is a flexible tubular plastic film. This is folded in the width direction, then wound corelessly and pressed flat to obtain a flat wound product. As shown in FIG. 1, the flat surfaces of the front and back surfaces, which are the result of pressing the flat wound object flat, are smooth surfaces, and among the four surfaces existing between the front and back smooth surfaces, folding of continuous tubes facing each other is possible. The surface that looks like a spiral is defined as the spiral surface, and the surface where the spiral pattern is not visible is defined as the folding surface. As the flat wound material, one in which the winding start end portion of the continuous tube is pulled out from the center portion is used. This winding start end needs to be drawn out longer than one of the folding parts, and the leading end of the drawn winding start end serves as a drawing end.

The rigid plate in the present invention has substantially the same width as the folded portion of the flat wound product, and the length is the sum of the length of the spiral portion and the length of the protruding portion. That is, when a flat wound material is placed on the center of the rigid plate and one of the folding parts is aligned with the rigid plate,
The protruding portion remains on the side of the other folding portion. The protrusion is provided with a slit that does not allow a finger to enter and has a length that allows the cutting blade to be sandwiched at the bottom thereof. Further, the rigid plate may be rigid enough not to be easily broken by the force of a finger. The cutting blade may be provided on one surface of the protruding portion, but it is preferable that it is sandwiched at the bottom of the slit for safety. To sandwich the cutting blade, a paperboard or a plastic sheet is used.
One piece may be stuck, or two protruding parts may be stuck together. Further, depending on the type of the cutting blade or the rigid plate, the cutting blade may be embedded and sandwiched in the central portion of one rigid plate.

The strip-shaped sheet of the present invention is not particularly limited as long as it is a material that is flexible and has sufficient strength so as not to be broken until the continuous tube is used. That is, the flat wound material is placed on the rigid plate and integrally wound so that both ends are overlapped. When wrapping, the flat wound material is overlapped with the protruding portion left, and further wound so that the folding portion located on the protruding portion side is slightly exposed. At this time, the pull-out end part that has been partially pulled out is exposed from the gap between the strip-shaped sheet and the spiral portion toward the protruding portion. The strip-shaped sheet is obtained by winding the rigid plate and the flat wound material, and then sticking the both ends together. The attachment site is preferably the back surface of the rigid plate, but it may be the front surface or the side part. Also, using a strip-shaped sheet shorter than the circumference of the rigid plate on which the flat wound material is placed,
Both ends of the strip-shaped sheet may be directly attached to the back surface of the rigid plate.

In the present invention, it is important to wind the strip-shaped sheet so that the folded portion located on the protruding portion side of the flat wound article is slightly exposed. The resistance required for the continuous tube not to be pulled out in a nodular form is obtained by the resistance of a single cord-like tube drawn from the central part through a narrow passage between the spiral part and the strip-shaped sheet. To be Even if the contents decrease, the necessary resistance is maintained because they are not pulled out in a nodule shape. This is because the continuous tube drawn out from the central part is unwound from a narrow passage while causing an unnatural twist.

Further, it is preferable to adhere the rigid plate and the continuous tube in advance so that the rigid plate and the continuous tube are not separated when the number of the continuous tubes decreases. Also, when attaching both ends of the strip-shaped sheet,
When a removable adhesive is used, it can be re-peeled even if looseness occurs between the rigid plate and the flat wound product, and can be re-adhered properly. Since the cut continuous tube is connected to one end to form a bag, the continuous tube can be used as a bag having an arbitrary length.

[0012]

The present invention folds a tubular plastic film into a narrow width, flatly presses a continuous tube for a bag that is wound corelessly from the end, and flattenes the smooth surface on both sides, the spiral part on both ends, and the folded part on both ends To form. This is a flat wound product in which the winding start end is pulled out to one of the folding parts from the spiral part and is wound so that the folding part located on the projecting side is slightly exposed. In this way, the winding start end drawn out from the center of the spiral part is immediately bent at a substantially right angle, and a narrow passage is formed before reaching the end of the strip-shaped sheet on the protruding side of the end of the spiral part. When a continuous tube is pulled out like a nodule or when the continuous tube is tensioned on the cutting blade during cutting, the continuous tube may be pulled out behind to loosen the tension and reduce the sharpness. There is no.

Further, when the continuous tube is pulled out and cut to a required length and used, a container such as a bag, a box, or a tubular sack is not required, but simply placed on a rigid plate and wrapped with a strip-shaped sheet. Since this is sufficient, there is an advantage that the labor for passing through the stenosis extraction hole can be saved and the manufacturing is extremely easy.

1 shows an embodiment of the present invention, FIG. 1 is an exploded perspective view of a continuous tube distribution set of the present invention, and FIG. 2 is FIG.
3 is a side view of FIG. 2 as seen from the side of the protrusion.

Reference numeral 1 denotes a flat wound product in which a flat polypropylene-made continuous tube having a thickness of 20 μm is further wound corelessly from the end and pressed flat, and has a wide smooth surface 2 on both sides and both smooth surfaces. It is composed of a spiral portion 3 that looks like a spiral when wound between two, and a thin folded portion 4 formed between the front and back smooth surfaces. A winding start end 5 extends from the center of one of the spiral portions 3, and at the same time as being drawn out, the winding start end 5 is bent at a substantially right angle and protrudes from one of the folding portions 4, and this protruding portion is a drawing-out end 6.

The flat wound article 1 is placed on a rigid plate 7 as shown in FIG. The portion of the rigid plate 7 where the flat wound material is not placed is the protruding portion 8. As the rigid plate 7, in this embodiment, a paper plate having a thickness of 1 mm and a vinyl chloride plate having a thickness of 0.5 mm are used. Further, the flat wound product 1 and the rigid plate 7 were bonded together with an adhesive. Reference numeral 9 is a slit, and 10 is a cutting blade sandwiched at the bottom of the slit 9. Reference numeral 11 denotes a strip-shaped sheet, which is printed on a thick wood-free paper and coated with a resin. The rigid plate and the flat wound material are wound around, and then stuck on the back surface of the rigid plate. Reference numeral 12 is a sticking part.

The protrusion 8 has a slit 9 as shown in FIG.
Is a length that is sufficiently exposed. Further, the strip-shaped sheet 11 was wound so that the folded portion 4 was sufficiently exposed and the pull-out end portion protruded from the strip-shaped sheet 11.

In use, the exposed pull-out end portion 6 may be pulled to pull out the continuous tube by a required length and then inserted into the slit 9. When the continuous tube is pulled out, it has a pull-out resistance due to the band-shaped material wound around it, and it is difficult to pull it out smoothly. Therefore, if the continuous tube is inserted into the slit and pulled, the continuous tube will not be pulled out later. Therefore, the continuous tube is sharply cut by the cutting blade provided at the bottom of the slit. The cut continuous tube is connected at one end to form a bag, and a bag having an arbitrary length can be freely manufactured.
