A wining start end which protrudes from a central part of the wound tube is adhered through an adhesive to a rear surface of a part surrounded by the weakening line and fixed to a rear surface of the hole piercing part 3. When the hole piercing part 3 is drawn outside from the weakening line, the winding start end fixed to the rear surface is drawn out together.

Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention relates to a package containing a continuous tube, in which a continuous tube wound without a core is housed in a tray-shaped container and sealed with a lid plate having a perforation. By tearing off the section, the end of the roll is drawn out along with the perforation forming section, and the continuous tube that is drawn out is cut to a desired length and one end is tied to form a continuous tube that can be used as a bag. Regarding packaging.

[Prior Art] Japanese Patent Application Laid-Open No. 59/1999 discloses a technique for winding and storing a continuous tube for bags, unrolling it from the end, cutting it to any length, and tying one end to use it as a bag of any length. −
This method is disclosed in Japanese Utility Model Publication No. 163158, Japanese Utility Model Application Publication No. 59-175033, and the like. When winding a continuous tube, there is one in which the tube material is folded flat to a width that is easy to handle, and then wound without a core from the end. There is also a technique of storing this in a tray-shaped container with a flange around the periphery and sealing it with a lid plate having a shape and size that matches the flange. In this case, a method is adopted in which a perforation is provided in the lid plate and the winding start end, which will become the drawer end, is pulled out from the perforation.

0003

[Problems to be Solved by the Invention] In the production of conventional packages containing continuous tubes, it was necessary to draw out the ends of the wound continuous tubes and set them by passing through narrow pull-out holes. Since this work requires fingertips, it is difficult to mechanize it. The package housed in the above-mentioned tray-shaped container can be delivered to the consumer as it is without the need to pass through the narrow draw-out hole and set it. This is due to the fact that the consumer is able to pull out the end of the winding by themselves through a hole provided in the cover plate.

[0004] However, although it is possible to pull out the winding start end from the perforation provided in the lid plate, it is somewhat difficult, and it would be easier if a tool with a sharp tip is used. Therefore, there has been a need for a technique that allows the consumer to more easily pull out the winding start end from the perforation provided in the lid plate without using any tools.

[0005]

[Means for Solving the Problems] The present invention provides a continuous tube-containing package that does not require cueing during the manufacturing process and allows the consumer to create a constricted pull-out hole by himself/herself, in which case the end of the roll is inevitably pulled out. The purpose is to provide a package consisting of a continuous tube housed in a tray-shaped container, in which all or part of the lid plate of the container near the end of the wound material is removed. A perforation forming part surrounded by a weakened line is provided, and an adhesive is applied to the back side of this part, and the winding start end protruding from the center of the continuous tube wound on the adhesive is adhered, The present invention is characterized in that the flange portion is provided with means for cutting the continuous tube.

[0006] The continuous tube in the present invention has a diameter of 7 to 30μ.
It is made by folding a thin tube made of plastic such as polyethylene or polypropylene in the width direction and having the strength of a bag, and then winding the tube without a core from the end. As a folding method, it is also possible to adopt the usual method of first stacking two flat tubes, folding the tubes in two or three, and further folding the tubes to a predetermined width.

A more preferred method is to alternately invert and fold the continuous tube into a bellows shape in its cross section. When folded like this, it looks the same as a normal folded film, but it is actually folded into a bellows shape in the width direction, so it is easy to open the cut after cutting by holding any two points and pulling it. The bag can be opened.

[0008] When the tube folded in the width direction in this manner is wound without core from the end, a rather flat wound product as shown in FIG. 3 is obtained. The surrounding area is a smooth winding surface, and the end of the winding is fixed with adhesive tape or the like to prevent the winding from collapsing. Flat annular winding lines are visible at both winding ends, and the winding start end protrudes from the center of one winding end.

[0009] The container for storing the wound material has a horizontal flange around the periphery, and the main body only needs to be wide and deep enough to comfortably accommodate the continuous tube, and the continuous tube can be automatically inserted into the main body. I can go. At this time, it is preferable that the winding start end is slightly unwound upward from one winding end of the continuous tube. The container has a lid plate that matches the flange, and by aligning and bonding the lid plate to the flange of the container, a sealed container containing a rolled continuous tube is obtained.

[0010] The lid plate is provided with a perforation forming portion. Its position is close to the end of the winding on the winding surface, preferably in contact with the end of the winding, and its size is such that when unwinding the continuous tube, it will not be unrolled all at once in the form of a lump. This is enough to provide appropriate resistance to the bag tube. The perforation forming portion may be surrounded by lines of weakness such as perforations. Adhesive is provided on the back side of the perforation forming part. During manufacturing, when a rolled article is stored in a container and the lid plate is brought into close contact with the flange of the container, the end of the continuous tube that projects inevitably comes into contact with the back surface of the perforation forming part and is bonded. When opening the seal, by pressing the hole forming part, a part of the cover plate is torn along the line of weakness, forming a narrow extraction hole. At this time, by pulling the torn perforation forming part, the winding start end bonded to the back side of the perforation forming part is pulled out together, allowing the consumer to easily locate the beginning of the winding.

[0011] The perforation forming part may be a part surrounded in whole or in part by a line of weakness, and a perforation can be formed by pressing this part with a finger. For example, as shown in Fig. 1, two infold lines are provided almost parallel to the center of the perforation forming part, and the part where the two infold lines intersect with the line of weakness is left unweakened, or the normal high-level weakening line is By making the line of moderate weakening less weak, that is, slightly weakened, two perforations are created along the line of weakness by pressing with two fingers on both sides of the two folded lines, If the two fingers are pulled out together, both ends of the part sandwiched by the inward fold line can be torn off and the continuous tube can be easily pulled out with a continuous tube attached to the back side, as shown in FIG. Alternatively, when forming a perforation by leaving a part of the perforation forming part with an outward fold line or a moderately weakened line, the hole is opened with the outward fold line or moderately weakened line left. When opening, the winding start end is naturally glued to the back surface, so the winding start end can be easily pulled out. Then, if necessary, the outer fold line or the moderately weakened line may be cut, or the outer fold line or the moderately weakened line may be left in the form of a hinge for use as shown in FIG.

[0012] The flange around the container is provided with cutting means. Any safe cutting means can be used. The position where the cutting means is provided can be appropriately selected so that the cut end remaining after cutting is long enough to be easily pinched with fingers for the next use, and long enough to not get in the way when stored. In use, the cut end is pinched and pulled out to the required length through the constricted extraction hole, cut, one end is ligated, and the other end is spread to form a bag of any length.

[0013]

[Operation] The present invention is a package in which a tube-shaped wound film is housed in a container having a flange around a tray type, and a plate-shaped lid plate is brought into close contact with the flange. In order to form a constricted pull-out hole during use, a perforation forming portion is previously provided in the lid plate in the shape of the constricted pull-out hole by surrounding the entire periphery or a portion of the circumference with weakened lines. Moreover, by applying adhesive to the back side of the area surrounded by the line of weakness, the winding start end protruding from the center of the continuous tube wound during the manufacturing process comes into contact with the adhesive, and the back side of the hole forming part Fixed. A perforation forming part is punched out from the weakened line, and when the tube is pulled out to the outside, the winding start end bonded to the back side is also pulled out, and the continuous tube is then smoothly pulled out from the narrowed draw-out hole that has been formed.

Reference numeral 13 is a slit provided in the flange 2 into which fingers cannot be inserted, and reference numeral 14 is a cutting blade sandwiched between the flange 2 and the cover plate 4 at the back of the slit 13. Reference numeral 15 denotes an adhesive tape for fixing the winding end portion 16.

In use, when the area between the two internal fold lines 6 of the perforation forming part 3 is pressed with two fingers, the area between the two internal fold lines 6 is left in the center, and the area between the two internal fold lines 6 is left in the center. When a perforation is generated and the line of moderate weakness 19 is torn and pulled outward, as shown in FIG. It's being pulled out. After pulling out the necessary amount of continuous tube 9,
The cutting blade 1 can be inserted into the slit 13 provided in the flange 2.

FIG. 4 shows another embodiment of the present invention, in which a perforation forming portion 3 is formed by surrounding a semicircular high-level weakening line 5 and the remaining part with a straight outer fold line 18. In this case, the continuous tube 9 is pulled out from the semicircular constricted pull-out hole 17 with the outer fold line 18 remaining in the form of a hinge and leaving a semicircular piece of paper behind.

[0017]

[Effects of the Invention] By using the packaging body of the present invention, it becomes easy to mechanically and efficiently store and seal continuous tubes. The starting end can be pulled out reliably. In particular, even if the end of the winding is not pulled out, the consumer can inevitably pull it out when opening the package for use, eliminating the need for the work of pulling out the beginning of the winding, which required the most labor in production.
