Description

  The present invention relates to a paper cup recycling method.

  In general, from the viewpoint of ecology, such as preserving the global environment and preventing global warming, used paper cups that are frequently used in vending machines that provide beverages are also recycled as much as possible without incineration. Therefore, there is a need for a technique for efficiently collecting used paper cups and reusing them as recycled paper.

  By the way, when collecting used paper cups, if you put a plastic bag on the collection box in advance and put the paper cups in it freely, the paper cups will become bulky, and a small amount of paper cups will make the inside of the box It becomes full soon and the collection work becomes frequent, and the collection efficiency is poor.

  Therefore, in the prior art, as a collection device for such used paper cups, a partition is provided inside the frame, and the paper cups are stacked and thrown into each interior partitioned by the partition. Thus, a paper cup that improves the collection efficiency of the paper cup has been proposed (see, for example, Patent Document 1).

JP 10-23003 A

  However, the prior art described in the above-mentioned Patent Document 1 focuses only on the viewpoint of how to efficiently collect used paper cups without bulking them. In what form the cup is collected, the wasteful work associated with the collection can be omitted, and the point that it can be efficiently recycled is not sufficiently considered.

  That is, in the prior art described in Patent Document 1, the divider into which used paper cups are put is made of plastic, and the divider is supported by a metal frame. For this reason, in order to recycle the paper cup, after removing the partitioning tool from the frame, it is necessary to take out only the paper cup from the partitioning tool, which requires extra work.

  Further, if the frame or the partitioning tool is used as it is for a long period of time, the dirt becomes conspicuous and unsanitary, so it is necessary to regularly clean the partitioning tool and the frame. In addition, since a tank for pouring and throwing away the leftover beverage is also required, this tank also needs to be periodically cleaned for hygiene, and extra labor is required.

  The present invention has been made to solve the above-mentioned problems, and can eliminate wasteful labor associated with collecting used paper cups as much as possible, and can be reused as recycled paper efficiently even after collecting paper cups. An object of the present invention is to provide a paper cup recycling method that can be used.

In order to achieve the above object, the paper cup recycling method of the present invention collects and collects used paper cups by stacking them in a paper collection box containing paper partition plates ,
The collection box has at least a surface excellent in water repellency, and at least a blotting paper having water absorption is disposed inside the bottom surface.
Recovered paper cups the collection box, and conveyed to the partition plate and blotting recycling every paper plant, the recovered paper cup and the collection box together waste paper pulping and the partition plate and blotting paper, the recycled paper used paper pulp It is characterized by playing.

  In this case, the collection box may employ a configuration in which at least the surface is excellent in water repellency and at least a blotting paper having water absorption is disposed inside the bottom surface.

  Moreover, the said collection box can be formed with the corrugated cardboard which recycled the used paper which was the raw material of the packaging material for drinks.

  Further, the collection box can be formed of corrugated cardboard whose front paper is made of paper having excellent water repellency and whose back paper is made of paper having water absorption.

According to the present invention, since used paper cups are stacked and collected in a paper collection box in a nested manner, the paper cups can be efficiently collected without being bulked as in the prior art. Moreover, since the collection box, partition plate, and blotter paper for collecting the paper cup are all made of paper, the paper cup can be transported to the recycling plant as it is together with the collection box , partition plate, and blotter paper to be recycled into pulp. it can. Therefore, even after collecting the paper cup, it can be efficiently reused as recycled paper without any extra effort.

  In this case, if a configuration is adopted in which at least the surface is excellent in water repellency and a blotting paper having water absorbability is disposed at least inside the bottom surface as the collection box, the surface is hardly soiled and cleanliness is maintained. Even if leftover beverage spills into the collection box, it is absorbed by blotting paper placed inside the bottom of the collection box. There is no need for regular cleaning. For this reason, extra labor and labor associated with the collection of the paper cup can be saved.

  In addition, when the collection box is made of corrugated cardboard made from recycled paper used as a packaging material for beverages, it is stronger and harder than ordinary corrugated cardboard. The collection box is not easily damaged, and used paper cups can be reliably collected.

  Furthermore, when the above collection box employs a configuration in which the surface paper is made of paper with excellent water repellency and the back paper is made of corrugated cardboard made of paper having water absorption, the surface of the box is hardly stained, In addition, even if leftover beverage spills into the collection box, it will be absorbed by the back paper and the beverage will not ooze up to the surface of the box due to the water repellency of the surface. it can. In addition, it is not necessary to separately arrange water-absorbing paper inside the bottom surface of the recovery box, and the configuration of the recovery box is simplified.

  Hereinafter, the paper cup recycling method of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a system diagram showing a paper cup recycling method according to an embodiment of the present invention, FIG. 2 is an exploded perspective view showing a part of a collection box used when the method is applied, and FIG. 3 is a collection perspective view. It is sectional drawing of the cardboard used as a raw material of a box.

  The paper cup recycling method of the present invention is to collect used paper cups 1 by stacking them in a paper collection box 2 in a nested manner, and transport the collected paper cups 1 together with the collection box 2 to a recycling plant F. The paper cup 1 and the collection box 2 collected in the recycling factory F are both converted into used paper pulp, and the used paper pulp is recycled into recycled paper.

  Specifically, for example, a paper collection box 2 is installed adjacent to a vending machine in which the paper cup 1 is used. At that time, a paper partition plate 3 is also stored in the collection box 2 in advance, and a blotting paper 4 having a water absorption property such as a coaster sheet is disposed in the bottom surface of the collection box 2. Then, the paper cups 1 are sequentially stacked in a nested manner into each of the interiors separated by the partition plate 3 (S1).

  If the inside of the collection box 2 is almost filled with the paper cup 1, the lid portion 2a of the collection box 2 is closed, and then the handle portion 2b is gripped to mount the collection box 2 on a loading platform of an automobile not shown. Then, the paper cup 1 is collected together with the collection box 2 and the partition plate 3, and they are conveyed to the recycling factory F (S2). Therefore, the collection box 2 serves not only for the simple collection of the paper cup 1 but also for the conveyance and storage.

  Then, in the recycling factory F, the recovered paper cup 1, the recovery box 2, and the partition plate 3 are all turned into used paper pulp (S3), and then this used paper pulp is recycled into recycled paper (S4). The recycled paper thus regenerated is processed into various paper products (S5). At that time, a part of the paper product is processed again as the collection box 2 or the partition plate 3.

  Here, both the collection box 2 and the partition plate 3 are formed of corrugated cardboard (so-called Mildan) 5 made by recycling waste paper made of virgin pulp, which was a material for beverage packaging materials such as milk packs and sake packs. It is a thing. Such a corrugated cardboard 5 has a weight of 200 g / m2 or more for the front paper 5a and the back paper 5b, and 150 g / m2 or more for the core paper 5c sandwiched between the two papers 5a and 5b. It is strong and hard, has little deterioration, and is strong against water, so that the collection box 2 and the partition plate 3 are not easily damaged, and the used paper cup 1 can be reliably collected. Moreover, the collection box 2 and the partition plate 3 are formed of a material having excellent water repellency.

  The paper having excellent water repellency is impregnated with, for example, heat-meltable resin, fatty acid emulsion, vinylidene chloride resin, nitrified cotton resin, paraffin wax, plastic emulsion, etc. However, the present invention is not limited to these. However, the present invention is not limited thereto. Reference numeral 5e denotes a paste such as corn starch for integrally joining the front paper 5a and back paper 5b of the corrugated cardboard 5 to the core paper 5c.

  As described above, in this embodiment, the used paper cups 1 are collected by stacking them in a paper collection box 2 in a nested manner, so that the paper cups 1 are efficiently collected without being bulked as in the prior art. be able to. Moreover, since the collection box 2 and the partition plate 3 for collecting the paper cup 1 are all made of paper, the paper cup 1 together with the collection box 2 and the partition plate 3 is transported to the recycling plant F as it is to be recycled into pulp. Can do. Accordingly, the paper cup 1, the collection box 2, and the partition plate 3 do not need extra labor and labor after collection, and can be efficiently reused as recycled paper.

  In addition, the collection box 2 has excellent water repellency on the surface, and the absorbent paper 4 having water absorption is arranged inside the bottom surface, so that the surface is difficult to get dirty and can be kept clean. In addition, even if spilled beverage is spilled into the collection box 2, it is absorbed by the blotting paper 4, so there is no need for a tank to wash away and leave the spilled beverage, and there is no need to clean the collection box 2 regularly. . For this reason, extra labor and labor associated with the collection of the paper cup 1 can be saved.

  In addition, although the collection box 2 of said embodiment is formed using the corrugated cardboard (mildan) 5 which recycled the used paper which was the raw material of the packaging material for drinks, it is not restricted to this structure, For example, FIG. It is also possible to use a cardboard 5 ′ configured as shown in FIG. That is, the corrugated cardboard 5 ′ shown in FIG. 4 is obtained by recycling used paper made of virgin pulp whose surface paper 5a and core paper 5c are materials for beverage packaging materials, and the surface paper 5a is water-repellent. On the other hand, the back paper 5f is made of blotting paper having water absorbency such as coaster paper.

  When the corrugated cardboard 5 ′ having this configuration is used, the surface paper 5a is excellent in water repellency, so that the surface is not easily soiled. Since the absorbent paper 5f absorbs water and the front paper 5a is excellent in water repellency, the beverage absorbed by the absorbent paper 5f on the back surface does not ooze out to the box surface. Can keep. In addition, since there is no need to separately arrange a dedicated blotting paper inside the bottom surface of the collection box as in the above embodiment, the configuration of the collection box becomes simple.

  With the above configuration, the present invention can realize transportation and transportation after collection at a low price. Further, the recycled paper product can be recycled and reused for notebooks or the like required in the office.
