Description

Label for drinking water containers that is easy to separate {EASILY SEPARABLE LABEL SHEET FOR BEVERAGE CONTAINER}

The present invention relates to an easily separable label for a drinking water container, and more specifically, to facilitate recycling of the drinking water container by configuring a label tightly bonded to the outer surface of the drinking water container to be easily separated and removed from the container. It's about labels.

In general, drinking water containers prepared to accommodate liquid raw materials can store the raw materials airtight, are easy to use, and are safe in terms of hygiene, so they are widely used as containers for various beverages and dairy products.

Such drinking water containers are prepared in the shape of bottles or cans made of various materials such as plastic such as PE and PET, glass, and aluminum, and have the entrance sealed, and a label with the product name or various descriptions printed on the outer side is attached.

Labels attached to drinking water containers mainly use heat-shrink film. Heat shrinkable film is a polyester film that has the characteristic of shrinking when heat is applied to the label. Therefore, labeling is possible to reflect the various shapes of drinking water containers.

The labeling process for drinking water containers involves wrapping a printed and cut heat-shrinkable film around the outer surface of the container, gluing one end to temporarily bond it, and then applying steam or heat to shrink and bond it so that it adheres closely to the exterior of the drinking water container.

Korean Patent No. 10 - 1458662 uses a heat-shrinkable film that heat-shrinks with the film width direction as the main shrinkage direction, and is cut according to the packaging object and has both ends in the film width direction glued to form an annular body of the packaging object. A label in which at least part of the outer periphery is covered by heat shrinking, the tearing strength at a right angle in the direction perpendicular to the main shrinkage direction (film longitudinal direction) is 100 N/mm to 310 N/mm, and the tear strength in the direction perpendicular to the main shrinkage direction is 100 N/mm to 310 N/mm. Constructs a label characterized in that the tensile breaking strength in the direction (film longitudinal direction) is 50 MPa or more and 300 MPa or less.

Meanwhile, plastic bottles, which are mainly used as disposable drinking water containers, are made of polyethylene terephthalate (PET) as the main raw material, and are recycled items with high added value among plastics. In addition, containers made of glass or aluminum cans are also representative items that are separated and recycled.

In order to recycle such drinking water containers, a process of separating and removing the label attached to the outside is essential, and an automatic label removal device is generally used.

As an example, Korean Patent No. 10-0875241 includes a PET bottle transfer unit provided with a hopper that accommodates PET bottles and a mounting portion that divides and loads the PET bottles supplied from the hopper in a certain amount, and sprays high-pressure washing water toward the PET bottles in the mounting portion to spray the outer surface of the PET bottles. It consists of a label removal device for PET bottles that includes a label removal unit that removes the labels, and a screen that removes the residual washing water and residual labels on the PET bottles supplied from the PET bottle transfer unit and then transfers the PET bottles to the next unit.

As another example, Korean Patent No. 10-0180891 discloses a label removal method for removing labels from PET bottles, in which a bale of waste PET bottles compressed and bound by a compressor is supplied to a bale breaker through a conveyor. , The bale breaker ensures that the waste PET bottles are separated from the bundled state during compression packaging, and the separated waste PET bottles are supplied to the label stripper by an inclined conveyor, and a plurality of strip pins attached to the outer circumference of the strip roller and the strip roller. When the strip roller is rotated by the motor due to the fixing pin installed in the front, scratches are created on the label attached to the surface of the PET bottle. In this way, the PET bottle that has passed through the label stripper passes through the trommel, causing scratches in the label stripper. PET bottles stored in the hopper after passing through an inspection conveyor and an inclined conveyor are removed from debris and foreign substances, and undergo a washing and rinsing process to completely remove the label. This constitutes a label removal method using a label stripper.

Korean Patent No. 10 - 1458662 (2014.11.05) Korean Patent No. 10 - 0875241 (2008.12.19) Korean Patent No. 10 - 0180891 (1999.05.15) Korean Patent No. 10 - 1926127 (2019.02.26)

The label for drinking water containers to which the above-described prior technology is applied is made by wrapping a printed and cut heat-shrinkable film around the outer surface of the drinking water container, gluing one end to temporarily bond it, and then applying steam or heat to shrink and bond it to adhere to the outer shape of the container. It is made in the form

However, for example, in the process of recycling plastic drinking water containers, if the container is melted with a label attached, the quality of the recycled raw material will significantly deteriorate, so a process to remove the label is inevitable.

In the past, labels attached to drinking water containers were removed by workers manually peeling them off using tools such as hands or knives. However, because the labels made of heat-shrink film were tightly bonded to the outer surface of the container, workability and productivity were improved. There were significantly fewer problems.

Recently, label removal work has been automated using an automatic label removal device. The automatic label removal device to which the prior art is applied consists of a series of components that spray high-pressure washing water into a drinking water container or physically remove it using a scraper. .

However, this prior art has the problem of increasing the economic burden due to device construction, maintenance, and additional processes because it requires additional pre-processing by providing a separate automatic label removal device in the recycling system for drinking water containers.

Accordingly, the present invention was invented to solve the problems of the prior art as described above.

The label for an easy-to-separate drinking water container to which the technology of the present invention is applied is a label that is tightly bonded to the outer surface of the container by heat shrinkage so that it can be easily separated and removed from the container, making recycling of the drinking water container more smooth. Please note that it is about.

For this purpose, the label for an easily separable drinking water container of the present invention includes a cut portion 110, a grip ring 120, a cut notch 131 and 132, and an uncut connection portion 140, as shown in FIGS. 1 to 4. ) and a cut thread 150, and is specifically as follows.

The label is made of a heat-shrinkable film material, has the product name printed on it, and is tightly coupled along the outer circumference by heat-shrinking to correspond to the external shape of the drinking water container.

In general, labels for drinking water containers are tightly attached to the container, so it is not easy to remove them by hand after using the drinking water container. In particular, for children or infants with weak finger strength, it is virtually impossible to separate and discharge the label.

The label of the present invention is provided with a cut portion 110, and a first cut line 111 and a second cut line 112 are formed from the upper end of one side of the label to the lower end so that the label can be cut.

The first cut line 111 and the second cut line 112 are provided by forming punching holes at regular intervals on the label. Punching holes can be applied in a variety of ways, such as circular, straight, or diagonal shapes, depending on the thickness of the label and the design of the drinking water container.

The first cut line 111 and the second cut line 112 are formed in parallel lines from the upper end of one side of the label to the lower end, and are vertical or diagonal, or diagonal and vertical as shown in FIG. 7. It is provided to be formed in parallel.

The first cut line 111 and the second cut line 112 are arranged in parallel lines at a certain distance from each other. In the vertical type, the cut portion 110 is formed to correspond to the length of the top and bottom of the label to form the shortest cut section. The diagonal type is formed in a diagonal direction over a certain section along the outer circumference of the label, forming a longer cutting section than the vertical type. The diagonal type takes into account the characteristics of the label that adheres closely to the drinking water container due to heat shrinkage, and can require less force when cutting compared to the vertical type. When the length of the drinking water container is long, the diagonal shape and the vertical shape are formed in parallel.

At the end of the second cut line 112, an uncut connection portion 140 is provided with a certain length on the opposite side of the grip ring 120, which will be described later.

The uncut connection portion 140 is a section in which a punching hole is not formed on the label at the end of the second cut line 112. Therefore, the second cut line 112 is the first cut line 111. Formed shorter.

The non-cut connection portion 140 has an end of the second cut line 112 in the final section of the first cut line 111 and the second cut line 112 that is initially cut by the gripping ring 120 below. It is provided so that it can be peeled off and separated in this connected state. Therefore, in the label of the present invention, the gripping ring 120, the cut portion 110, and the label can be separated as one piece without being separated separately.

The gripping ring 120 is provided in a ring shape selected from among the horizontally long rectangle, oval, and diamond when in a circular state when heat shrinking the label, and when deployed to the outside of the drinking water container, the hole in the center is opened up and down to open the finger. Configure to enable insertion.

That is, the gripping ring 120 is maintained in a tightly coupled state along the curved surface of the drinking water container with the size of the hole minimized in the circular state in consideration of ease of cutting and workability when heat shrinking when manufacturing the label. When deployed with a finger, it is configured to produce an operating state that opens the hole in the center.

The cutting notches 131 and 132 form recesses in a 'V' shape toward the first cutting line 111 and the second cutting line 112 on both sides of the connection area between the gripping ring 120 and the cutting part 110. and provide it.

The cutting notches 131 and 132 form pointed ends at the ends of the label at both ends of the gripping ring 120, and are provided so that the pre-cutting part 110 can be cut and cut by the gripping ring 120. .

Meanwhile, the first tear line 111 is provided with a built-in tear thread 150 that is made of a stronger material than the label and is formed linearly with a longer length than the first tear line 111 on the inside of the label.

The tearing thread 150 is similar to the label material, such as PP or PE, but is made of a strong material to reinforce the cutting force, and excluding the second cutting line 112 where the uncut connection portion 140 is provided, It is provided in the longitudinal direction inside the first cutting line (111) to ensure complete cutting.

The tip of the cut thread 150 is integrally attached to the grip ring 120. Accordingly, the cutting thread 150 and the cutting part 110 are configured to operate as one body by unfolding and pulling the grip ring 120.

The outline of the use state of the label for an easily separable drinking water container to which the technology of the present invention is applied, consisting of the above-mentioned structure, is as follows. The following description describes the present invention by way of preferred embodiments, so the present invention is not limited by the following examples, and it is natural that various modifications may be made without departing from the scope of the present invention. .

The label according to the present invention is tightly bonded to the outer surface by heat shrinking to correspond to the external shape of the drinking water container in which curves, irregularities, etc. are formed.

On one side of the label, a cut portion 110 is formed in a vertical, diagonal, or parallel diagonal and vertical form from the upper end of the label to the lower end.

At one end of the cutout portion 110, a gripping ring 120 protrudes and extends in a long transverse direction, in an oval shape, or in a diamond shape.

Inside the first cutting line 111 of the cutting part 110, a cutting thread 150 is installed along the longitudinal direction of the first cutting line 111 with one end attached to the gripping ring 120.

At the end of the second cut line 112, an uncut connection portion 140 is integrally connected to the label.

After using the drinking water container, the user removes the label so that the drinking water container can be used for recycling.

As shown in Figure 5, the user unfolds the gripping ring 120 from the drinking water container with his or her finger and inserts the finger into the hole formed in the gripping ring 120.

When the gripping ring 120 is pulled with a finger, the cut portion 110 is deployed from the drinking water container together with the grip ring 120, and cut notches are provided on both sides of the connection area between the grip ring 120 and the cut portion 110. (131, 132) primarily cuts the label, and cutting is performed along the first and second cut lines (111) and (112).

An uncut connection portion 140 is provided at the end of the second cut line 112 to stop cutting, but the first cut line 111 is completely cut by the cut thread 150 built into the first cut line 111. It is stolen.

The label is separated from the drinking water container as the first tear line 111 is completely cut, and at this time, the cut portion 110 and the label are separated as shown in FIG. 6 while being integrally connected by the uncut connection portion 140. and can be processed.

The label for an easily separable drinking water container according to the present invention as described above is made of a heat-shrink film material and forms a cut in the label that is tightly coupled to the outer surface of the container, but is a series that allows the label to be neatly separated and removed even with relatively weak force.
