Description

The present invention relates to a label package, a labeled container wrapped around the label package, and a method for manufacturing the labeled container.

Labeled containers are known in which a packaging label displaying the product name, design, manufacturer name, logo, product description, etc. is shrink-wrapped. In addition to the packaging label, a tack label that highlights the product's features, catch phrases, campaign information, etc. is also attached to the labeled container.

For example, Patent Document 1 discloses a multi-layer tack label that can be attached to an object. The multi-layer tack label includes a first label having a transparent attachment portion, and a second label that is peelably attached to a display portion connected to the attachment portion of the first label and has a display print layer.

However, it is difficult to automatically align and affix a tack label to a specified position on a packaging label. This is because when labeled containers with tack labels affixed are manufactured on a single conveyor line, the orientation of each container changes on the conveyor when the containers are moved after the packaging labels are shrink-wrapped. It is possible to introduce a device that unifies the orientation of the label after the containers are shrink-wrapped and before the tack label is affixed, but this poses issues in terms of installation space and cost.

It is also possible to attach a tack label to the packaging label beforehand and then shrink-wrap the packaging label around the container, but this can be problematic as the tack label may hinder the thermal shrinkage of the packaging label. Furthermore, the location where the tack label is affixed is limited because it is excluded from the area where the packaging label is cut. Also, if the tack label is affixed to the surface of the packaging label, there is a risk that the tack label may be peeled off and the information on the tack label may be stolen.

One aspect of the present invention aims to provide a labeled container in which a tack label is aligned and affixed to a predetermined position on a shrink label, preventing the tack label from being peeled off, and a labeled package or the like to realize the same.

In order to solve the above problem, a label package according to one aspect of the present invention is a label package comprising a shrink label that is heat-shrunk onto a container body to be packaged to package the container body, and a tack label that can be affixed to the container body, in which the shrink label, when rolled up before heat shrinking, forms a first space that contains the container body and the tack label, and is heat-shrunk at a predetermined packaging position, and at least a portion of the tack label is provided in a second space that is a part of the first space that is formed between the shrink label and the container body at the packaging position.

In addition, a labeled container according to one aspect of the present invention is a labeled container comprising a container body, a shrink label that is heat-shrunk onto the container body to package the container body, and a tack label that can be affixed to the container body, in which the shrink label is rolled up before heat shrinking and affixed to the container body within a first space that is formed to contain the container body, and at least a portion of the tack label is sandwiched between the shrink label and the container body.

In addition, a method for manufacturing a labeled container according to one aspect of the present invention includes a first step of attaching a tack label to a container body to be packaged, a second step of placing the tack label attached in the first step and the container body within a first space formed by rolling up the shrink label, and a third step of thermally shrinking the shrink label at a predetermined packaging position and sandwiching at least a portion of the tack label between the shrink label and the container body.

According to one aspect of the present invention, it is possible to provide a labeled container in which a tack label is aligned and affixed to a predetermined position on a shrink label, preventing the tack label from being peeled off, and a labeled package for realizing the same.

[Embodiment]
Hereinafter, one embodiment of the present invention will be described in detail. However, the following description is an example of a labeled container according to the present invention, and the technical scope of the present invention is not limited to the illustrated example.

(Outline of labeled containers)
Fig. 1 is a front view of a labeled container 100 according to an embodiment of the present invention. Fig. 2 is a top view of the labeled container 100. As shown in Figs. 1 and 2, the labeled container 100 is a container in which a container body 101 is packaged in a label package 10 composed of a tack label 11 and a shrink label 12.

The present invention was developed with great effort to enable the automatic manufacture of labeled containers 100, in which a tack label 11 is positioned at a predetermined position on a shrink label 12 that has been heat-shrunk onto a container body 101, on the same conveyor of a production line.

In the labeled container 100, the tack label 11 is attached at a position that does not interfere with the wrapping and thermal shrinkage of the shrink label 12, allowing for automatic production on the same conveyor of the production line.

(Basic structure of a container with a label)
The labeled container 100 includes a container body 101 and a label package 10. The container body 101 is a cylindrical container, and is, for example, a container that contains a product. Examples of the product include food, medicine, detergent, cosmetics, etc. Also, the container body 101 does not have to contain a product.

As shown in FIG. 1, the container body 101 includes a lid 13, a mouth 14, a shoulder 15, a body 16, and a bottom 17. The container body 101 is cylindrical (approximately cylindrical), but is not limited to this, and may be, for example, approximately prismatic or approximately spherical.

The mouth 14 is an outlet through which the contents are poured out. The lid 13 is removably attached to the mouth 14. Specifically, the mouth 14 is formed with a threaded portion (not shown) that screws into a threaded portion (not shown) formed on the inner peripheral wall of the lid 13. The container body 101 can be opened and closed by screwing the threaded portion of the lid 13 into the threaded portion of the mouth 14.

The shoulder portion 15 is a portion that protrudes radially outward from the mouth portion 14. The shoulder portion 15 has a shape in which the diameter gradually increases from the mouth portion 14 side toward the body portion 16 side. In other words, the shoulder portion 15 is a substantially conical portion that connects the mouth portion 14 and the body portion 16. The shape of the shoulder portion 15 is not particularly limited, and may be formed, for example, in a disk shape, an elliptical shape, a substantially elliptical shape, or a pyramidal shape. The body portion 16 extends in a cylindrical shape from the circular bottom portion 17 to the shoulder portion 15.

(Label packaging)
The label package 10 includes a tack label 11 and a shrink label 12.

The shrink label 12 is a label used to package the container body 101. For example, the name of the product contained in the container body 101 and a description of the product are printed on the printing section 12a as a symbolic display on the shrink label 12 to identify the packaged object. The shrink label 12 is heat-shrunk onto the container body 101 to be packaged, packaging the container body 101. When the shrink label 12 is in a rolled state before heat-shrunk, it forms a first space SP1 that contains the container body 101 and the tack label 11, and is heat-shrunk at a predetermined packaging position P. The shrink label 12 includes a tubular shrink label and a wrap-around shrink label.

When the shrink label 12 is a cylindrical shrink label, the container body 101 is packaged in the shrink label 12 as shown in FIG. 1. That is, the flexible sheet-like shrink label 12 is formed into a cylindrical shape (wound before heat shrinking), and the cylindrically formed shrink label 121 is placed over the container body 101 and placed at a predetermined packaging position P. Then, in this state, the shrink label 12 is heat shrunk to bring the shrink label 12 into close contact with the container body 101. In this case, the first space SP1 refers to the space formed during the time when the cylindrically formed shrink label 121 is moved to the predetermined packaging position P.

On the other hand, when the shrink label 12 is a wrap-around shrink label, the container body 101 is packaged with the shrink label 12 as follows. That is, the shrink label 12 is wrapped around the container body 101 (wrapped state before heat shrinking, see 7002 in FIG. 7). Specifically, one circumferential end 12b (see 7002 in FIG. 7) of the shrink label 12 is affixed to the container body 101 so that the shrink label 12 is positioned at a predetermined packaging position P, and the shrink label 12 is wrapped around the container body 101 and the other circumferential end 12c of the shrink label 12 is affixed so as to overlap the one end 12b. Note that 7002 in FIG. 7 shows the state before one circumferential end 12b of the shrink label 12 is affixed to the container body 101.

The shrink label 12 is thermally shrunk while wrapped around the container body 101, so that the shrink label 12 adheres closely to the container body 101. In this case, the first space SP1 refers to the space formed from the start of wrapping the shrink label 12, when one end 12b of the shrink label 12 is affixed to the container body 101, until the shrink label 12 is positioned at the specified packaging position P.

The material of the shrink label 12 is not particularly limited, and can be any common material, such as a heat-shrinkable synthetic resin film, a nonwoven fabric, a foamed resin film, or a laminate film of these. The shrink label 12 can be either transparent or opaque, but a transparent film is preferably used. The thickness of the shrink label 12 is not particularly limited, but can be, for example, about 8 μm to 200 μm, or about 20 μm to 80 μm.

(Tackle label)
As shown in FIG. 1, the tack label 11 is a label that can be attached to a container body 101, and is used, for example, in a campaign for promoting the sale of beverage products, and has campaign information and the like printed on it.

The tack label 11 is placed at a predetermined position on the shrink label 12. The predetermined position on the shrink label 12 may be, for example, near a symbolic display on the shrink label 12 for identifying the packaging object of the shrink label 12, and as one example, the predetermined position may be near the printed portion 12a on which the product name of the shrink label 12 is printed. This allows consumers to recognize the tack label 11 when checking the product name, so that campaign information, etc. printed on the tack label 11 can be reliably visually recognized by consumers.

In addition, by positioning the specified position of the shrink label 12 at a position where the printing on the tack label 11 does not overlap with the printing on the shrink label 12, the visibility of the tack label 11 can be improved.

Furthermore, by setting a predetermined position of the shrink label 12 so that the printing on the tack label 11 and the printing on the shrink label 12 overlap, the printing on the tack label 11 can be concealed by the printing on the shrink label 12. This allows the printing on the tack label 11 to be concealed by the shrink label 12, for example, when lottery results or application serial numbers are printed on the tack label 11 and the printing on the tack label 11 should not be visible to consumers until they purchase the product. This eliminates the need to cover the tack label 11 with a concealing sticker to conceal the printing, thereby reducing costs.

The tack label 11 is affixed to the container body 101 in the first space SP1, which is formed so that the shrink label 12 is wrapped around it before thermal shrinkage and contains the container body 101. In other words, the tack label 11 is affixed to the container body 101 in the first space SP1. In other words, the tack label 11 is affixed to the container body 101 in a position on the container body 101 that does not prevent the shrink label 12 from being wrapped around it before thermal shrinkage and being positioned in the specified packaging position P.

Therefore, the tack label 11 affixed to the container body 101 does not prevent the shrink label 12 from being placed at the specified packaging position P, and does not prevent the shrink label 12 from thermally shrinking. This allows the tack label 11 to be affixed to the container body 101 before the shrink label 12 is placed at the specified packaging position P for thermal shrinkage.

In addition, since the tack label 11 can be affixed to the container body 101 before the shrink label 12 is placed in the specified packaging position P, the position of the shrink label 12 can be aligned with the tack label 11 when the shrink label 12 is placed in the specified packaging position P. In other words, the tack label 11 can be placed in the specified position of the shrink label 12.

As a result, labeled containers 100 can be automatically manufactured on the same conveyor line that performs shrink packaging, with the tack label 11 aligned and affixed to a predetermined position on the shrink label 12.

At least a portion of the tack label 11 is provided in a second space SP2, which is a portion of the first space SP1, formed between the shrink label 12 and the container body 101 at the packaging position P. Here, the second space SP2 is a space formed between the heat-shrunk shrink label 12 and the container body 101. As a result, after the shrink label 12 is heat-shrunk, the clamped portion 11a, which is at least a portion of the tack label 11, is clamped between the shrink label 12 and the container body 101.

Therefore, the tack label 11 cannot be removed from the container body 101 unless the shrink label 12 is removed from the container body 101. This prevents the tack label 11 from being peeled off from the container body 101 at stores, etc., and therefore prevents theft of the tack label 11 at stores, etc., and the fraudulent taking of campaign information printed on the tack label 11. In addition, the tack label 11 can be reliably kept attached in a designated position on the shrink label 12 until it reaches the consumer.

Figure 3 is a front view showing an example of tack label 11. 3001 in Figure 3 shows tack label 11, and 3002 in Figure 3 shows tack label 111, which is a modified version of tack label 11.

As shown in FIG. 3, 3001, the tack label 11 has an attachment portion 11b that is attached to the surface of the container body 101, and a non-attachment portion 11c that is not attached to the surface of the container body 101.

The attachment portion 11b is formed, for example, by applying an adhesive to the tack label 11. For example, a pressure-sensitive adhesive can be used as the adhesive. A pressure-sensitive adhesive is a gel-like adhesive that has adhesiveness at room temperature and flows when pressurized, adhering to the adherend. Examples of pressure-sensitive adhesives include natural rubber-based, synthetic rubber-based, acrylic resin-based, polyvinyl ether resin-based, urethane resin-based, and silicone resin-based adhesives. The attachment portion 11b of the tack label 11 may be releasably attached to the container body 101.

The tack label 11 has a widthwise (x-direction) length that decreases from the non-attached portion 11c toward the attached portion 11b. Furthermore, at least a portion of the non-attached portion 11c is provided outside the second space SP2, and at least a portion of the attached portion 11b is provided within the second space SP2.

The tack label 11 provided in the second space SP2 is sandwiched between the shrink label 12 and the container body 101 after the shrink label 12 is thermally shrunk. Therefore, according to the above configuration, the widthwise length (L4) of the affixed portion 11b sandwiched between the shrink label 12 and the container body 101 is shorter than the widthwise length (e.g., L2) of the non-affixed portion 11c of the tack label 11 that is not sandwiched between the shrink label 12 and the container body 101. This makes it possible to shorten the circumferential length of the overlapping portion of the tack label 11 and the shrink label 12, thereby ensuring the printing area of the tack label 11 while suppressing wrinkles in the shrink label 12 after thermal shrinkage.

As shown in FIG. 3, the tack label 11 is preferably approximately trapezoidal, with the length of the lower base being L1, the length of the upper base being L2, and the height being L3, for example, L1 = 20 mm, L2 = 30 mm, L3 = 20 mm, or L1 = 20 mm, L2 = 25 mm, L3 = 20 mm. By making the tack label 11 the above size, even if the shrink label 12 is thermally shrunk, the tack label 11 and the shrink label 12 do not wrinkle or peel off, and the design of the labeled container 100 is improved.

On the other hand, for example, if L1 = 20 mm, L2 = 30 mm, and L3 = 25 mm, there is a risk that wrinkles will occur in the tack label 11 after the shrink label 12 is thermally shrunk. Therefore, if the tack label 11 is approximately trapezoidal, it is desirable to set L3 < 25 mm. This prevents wrinkles and peeling off of the tack label 11 and the shrink label 12, and allows the production of a labeled container 100 with a highly aesthetic design.

Furthermore, the tack label 11 is not limited to being approximately trapezoidal, but may be T-shaped as shown in tack label 111 of 3002 in Figure 3.

The tack label 111 has a first label portion 11d that is substantially rectangular and a second label portion 11e that is substantially rectangular with its longer side in the width direction. A part of the first label portion 11d is provided with an attachment portion 11b. The second label portion 11e is a non-attachment portion, and campaign information and the like is printed on the second label portion 11e. The width direction length of the first label portion 11d is shorter than the width direction length of the second label portion 11e, which is a non-attachment portion. The first label portion 11d is sandwiched between the shrink label 12 and the container body 101 due to the thermal contraction of the shrink label 12.

Because the second label portion 11e is a non-attached portion and is independent of the shrink label 12, it is possible to prevent the second label portion 11e, on which campaign information and the like is printed, from wrinkling. In addition, the area of the second label portion 11e can be increased, so a large display area for campaign information and the like can be secured. Furthermore, because the first label portion 11d is not related to the display area, the circumferential length of the portion where the tack label 111 and the shrink label 12 overlap can be shortened, so that wrinkling of the shrink label 12 after thermal shrinkage can be suppressed.

The material of the tack label 11 is not particularly limited, and general materials can be used. For example, synthetic resin films such as polyethylene-based and polyester-based, paper, nonwoven fabric, woven fabric, synthetic paper, and laminates thereof can be used for the tack label 11. For the tack label 11, synthetic resin films, paper, synthetic paper, or laminates of two or more types selected from these are preferable.

The tack label 11 may have heat shrinkability, but preferably has substantially no heat shrinkability. Having substantially no heat shrinkability means that the heat shrinkage rate in both the longitudinal and transverse directions is 5% or less, preferably 3% or less, and more preferably 1% or less.

The thickness of the tack label 11 is not particularly limited, but for example, when a synthetic resin film is used, it is 30 μm to 200 μm, and preferably 40 μm to 120 μm.

In this embodiment, the tack label 11 is affixed to the shoulder 15 of the container body 101 so that the attachment portion 11b faces the bottom 17 and the lower base of the approximately trapezoidal tack label 11 faces the bottom 17. In other words, the tack label 11 is affixed to the shoulder 15 of the container body 101, which has a smaller outer diameter than the body 16, which has the largest outer diameter when viewed from above, and which has a higher shrink rate of the shrink label 12 than the body 16. In this way, in this embodiment, the tack label 11 can be placed in the container body 101 within the first space SP1 by the simple method of affixing the tack label 11 to the shoulder 15 of the container body 101.

(Production method)
Fig. 4 is a flow diagram showing an example of a manufacturing method for the labeled container 100, and Fig. 5 is a diagram showing a schematic diagram of the manufacturing method shown in Fig. 4. An example of a manufacturing method for the labeled container 100 will be described below with reference to Fig. 4 and Fig. 5. The manufacturing method shown in Fig. 4 and Fig. 5 is a manufacturing method for the labeled container 100 when a cylindrical shrink label is used as the shrink label 12.

As shown in FIG. 4, first, the container body 101 to be packaged that has been transported by the conveyor is grasped, and the orientation of the container body 101 is unified based on an image of the container body 101 (step S1).

Next, while the container body 101 is fixed in the orientation of step S1, the tack label 11 is attached to a predetermined position of the container body 101, for example, by a labeler (step S2: first step, see 5001 in FIG. 5). Here, the predetermined position can be set arbitrarily, and may be set, for example, by the orientation of the lid portion 13 or the container body 101.

Then, while the container body 101 is fixed in the S1 orientation, the shrink label 12 (shrink label 121) rolled up into a cylindrical shape is placed over the container body 101 from above, for example, using a shrink packaging machine or the like, with the tack label 11 and container body 101 inside the first space SP1 (step S3: second step, see 5002 in FIG. 5). In other words, the position where the tack label 11 is affixed in step S2 is a position that does not interfere with the trajectory TR1 that the shrink label 12 follows when it is moved to the container body 101.

Then, based on the image of the shrink label 12 wrapped around the container body 101 in a cylindrical shape, the orientation of the shrink label 12 is adjusted and the shrink label 12 is placed in a predetermined packaging position P (step S4, see 5003 in Figure 5).

Finally, the shrink label 12 is thermally shrunk at the predetermined packaging position P, and at least a portion of the tack label 11, the clamped portion 11a, is clamped between the shrink label 12 and the container body 101 (step S5: third step, see 5004 in Figure 5).

According to the above manufacturing method, a labeler for the tack label 11 is installed just before the shrink label 12 is wrapped by the shrink packaging machine, and the tack label 11 is attached to the container body 101, so that the tack label 11 can be positioned at a predetermined position on the shrink label 12. In other words, according to the above manufacturing method, the position of the tack label 11 can be automatically regulated. This makes it possible to automatically manufacture labeled containers 100 with the tack label 11 positioned at a predetermined position on the shrink label 12 on the same production conveyor line.

Figure 6 is a flow diagram showing another example of a manufacturing method for a labeled container 100, and Figure 7 is a diagram showing a schematic of the manufacturing method of Figure 6. Another example of a manufacturing method for a labeled container 100 will be described below with reference to Figures 6 and 7. The manufacturing method of Figures 6 and 7 is a manufacturing method for a labeled container 100 when a wrap-around shrink label is used as the shrink label 12.

As shown in FIG. 6, first, the container body 101 to be packaged that has been conveyed by the conveyor is grasped, and the orientation of the container body 101 is unified based on an image of the container body 101 (step S11). Next, while the container body 101 is fixed in the orientation of step S11, the tack label 11 is attached to a predetermined position of the container body 101, for example, by a labeler (step S12: first step, see 7001 in FIG. 7).

Next, as shown in 7002 of FIG. 7, while the container body 101 is fixed in the S11 orientation, the shrink label 12 is wrapped around the container body 101, for example, by a shrink packaging machine, while the tack label 11 and the container body 101 are placed inside the first space SP1 (step S13: second step).

Specifically, one circumferential end 12b of the shrink label 12 is affixed to the container body 101 so that the shrink label 12 is positioned at the predetermined packaging position P, and the shrink label 12 is wrapped around the container body 101 and the other circumferential end 12c of the shrink label 12 is affixed so as to overlap the one end. Note that 7003 in FIG. 7 shows a state in which one end 12b and the other end 12c of the shrink label 12 are affixed to positions on the container body 101 that correspond to the tack label 11, and the shrink label 12 is positioned at the predetermined packaging position P.

Then, as shown in 7004 of FIG. 7, the shrink label 12 is thermally shrunk at a predetermined packaging position P, and the clamping portion 11a, which is at least a part of the tack label 11, is clamped between the shrink label 12 and the container body 101 (step S14: third step).

[Modifications]
Modifications of the present invention will be described below. For the sake of convenience, the same reference numerals will be used to designate members having the same functions as those described in the above embodiment, and the description thereof will not be repeated.

Figure 8 is a front view showing a labeled container 100A, which is a modified version of the labeled container 100. The labeled container 100 and the labeled container 100A differ in the shape of the container body 101A. The container body 101A has a shoulder 15, a body 16, a lower shoulder 15a that is a portion that protrudes radially outward from the lower part of the body 16, and a lower body 16a that extends cylindrically from the circular bottom 17 to the lower shoulder 15a. The diameter of the lower shoulder 15a gradually increases from the lower part of the body 16 toward the lower body 16a.

As shown in FIG. 8, in this modified example, the shrink label 12 covers the container body 101 over a portion of the shoulder 15, the body 16, the lower shoulder 15a, and the lower body 16a. The tack label 11 is attached to the shoulder 15 and lower shoulder 15a of the container body 101A so that the bottom (the side with the shorter width) of the approximately trapezoidal tack label 11 faces the bottom 17. The entire tack label 11 is covered by the shrink label 12 at the lower shoulder 15a, but if the shrink label 12 is transparent, the tack label 11 covered by the shrink label 12 can be seen.

In this way, even if the container body 101A has multiple body portions with different outer diameters, the labeled containers 100A can be automatically manufactured on the same conveyor of the production line by attaching the tack label 11 to the container body 101A in the first space SP1.

Figure 9 is a front view showing a labeled container 100B, which is another modified version of the labeled container 100. The labeled container 100 and the labeled container 100B differ in the shape of the container body 101B. The container body 101B has a shoulder portion 15 and a lower shoulder portion 15b whose diameter gradually decreases from the lower portion of the shoulder portion 15 toward the bottom portion 17.

As shown in FIG. 9, in this modified example, the shrink label 12 extends from the shoulder 15 to the lower shoulder 15b, covering part of the shoulder 15 and part of the lower shoulder 15b. At the shoulder 15, the tack label 11 is attached to the shoulder 15 so that the bottom base of the approximately trapezoidal tack label 11 faces the bottom 17, and the clamping portion 11a, which is at least a part of the tack label 11 including the bottom base, is clamped between the shrink label 12 and the container body 101B.

In addition, a roughly trapezoidal tack label 11 is affixed to the lower shoulder portion 15b so that the bottom base is on the shoulder portion 15 side, and the clamping portion 11a, which is at least a part of the tack label 11 including the bottom base, is clamped between the shrink label 12 and the container body 101B.

In this way, even if the container body 101B does not have a cylindrical body portion, the labeled container 100B can be automatically manufactured on the same conveyor of the production line by attaching the tack label 11 to the container body 101B in the first space SP1.

Figure 10 is a front view showing a labeled container 100C, which is yet another variation of the labeled container 100. The labeled container 100 and the labeled container 100C differ in the shape of the container body 101C. The container body 101C has an opening 19 formed at the upper end, and has a body portion 16c whose diameter gradually decreases from the opening 19 toward the bottom 17, with the upper end of the container body 101C being the maximum outer diameter.

As shown in FIG. 10, in this modified example, the shrink label 12 covers a portion of the body 16c in a band-like shape in the width direction. The approximately trapezoidal tack label 11 is affixed to the body 16c so that it fits inside the maximum outer diameter of the container body 101C, for example, and the clamping portion 11a, which is at least a portion of the tack label 11 including the bottom base, is clamped between the shrink label 12 and the container body 101C.

In this way, even if the container body 101C does not have a shoulder portion, the labeled container 100C can be automatically manufactured on the same conveyor of the production line by attaching the tack label 11 to the container body 101C in the first space SP1.

Figure 11 shows a labeled container 100D, which is yet another modified version of the labeled container 100. 1101 in Figure 11 is a front view of the labeled container 100D, and 1102 in Figure 11 is a side view of the labeled container 100D. The labeled container 100 and the labeled container 100D differ in the shape of the container body 101D. The container body 101D is approximately circular when viewed from the front and approximately elliptical when viewed from the side.

As shown in FIG. 11, in this modified example, the shrink label 12 covers the approximate center of the container body 101D in a band shape in the width direction. The approximately trapezoidal tack label 11 is affixed, for example, to a position that is inside the maximum outer diameter portion 18d in the circumferential direction of the container body 101D, and the clamping portion 11a, which is at least a part of the tack label 11 including the bottom base, is clamped between the shrink label 12 and the container body 101D.

In this way, by attaching the tack label 11 to a position inside the maximum outer diameter portion 18d, which is the largest outer diameter in the circumferential direction of the container body 101D, the tack label 11 can be attached to the container body 101D within the first space SP1. This allows labeled containers 100D to be manufactured automatically on the same conveyor of the production line.

〔effect〕
In the labeled container 100, the tack label 11 is affixed to the container body 101 in a first space SP1 that is formed so that the shrink label 12 is wound around the container body 101 before it is thermally shrunk and contains the container body 101. Therefore, the tack label 11 does not interfere with the shrink label 12 when the shrink label 12 is placed at a predetermined packaging position P where the shrink label 12 is thermally shrunk. This allows the tack label 11 to be affixed to the container body 101 before the shrink label 12 is placed at the predetermined packaging position P, i.e., before the shrink label 12 is thermally shrunk.

As a result, labeled containers 100 can be automatically manufactured on the same conveyor line that performs shrink packaging, with the tack label 11 aligned and affixed to a predetermined position on the shrink label 12.

After the shrink label 12 is thermally shrunk, at least a portion of the tack label 11, the clamped portion 11a, is clamped between the shrink label 12 and the container body 101.

Therefore, the tack label 11 cannot be removed from the container body 101 unless the shrink label 12 is removed from the container body 101. This prevents the tack label 11 from being peeled off from the container body 101 at stores, etc., and therefore prevents theft of the tack label 11 at stores, etc., and the fraudulent taking of campaign information printed on the tack label 11. In addition, the tack label 11 can be reliably kept attached in a designated position on the shrink label 12 until it reaches the consumer.

With this configuration, the tack label 11 is aligned and affixed to a predetermined position on the shrink label 12 without the need to introduce equipment with new functions, and the tack label 11 can be prevented from being peeled off, making it possible to manufacture better products than before. This will also contribute to achieving Goal 12 of the Sustainable Development Goals (SDGs), "Responsible Consumption and Production."

〔summary〕
The label packaging (10) of aspect 1 of the present invention is a label packaging comprising a shrink label (12) that is heat-shrunk onto a container body (101) to be packaged to package the container body, and a tack label (11) that can be affixed to the container body, wherein the shrink label, when rolled up before heat-shrunk, forms a first space (SP1) that contains the container body and the tack label, and is heat-shrunk at a predetermined packaging position (P), and at least a portion of the tack label (clamped portion 11a) is provided within a second space (SP2), which is a part of the first space, that is formed between the shrink label and the container body at the packaging position.

According to the above configuration, the tack label is present within the first space formed when the shrink label is in a rolled state before thermal shrinkage. Therefore, even if the tack label is affixed to the container body before the thermal shrinkage process, the tack label does not prevent the shrink label from being placed in the specified packaging position. This allows the tack label to be affixed to the container body before the shrink label is placed in the specified packaging position for thermal shrinkage.

In addition, since the tack label can be affixed to the container body before the shrink label is placed in the designated packaging position, the position of the shrink label can be aligned with the tack label when the shrink label is placed in the designated packaging position.

As a result, by using the label packaging body with the above configuration on the same conveyor line as the shrink packaging, labeled containers can be automatically manufactured with the tack label aligned and affixed to a specified position on the shrink label.

At least a portion of the tack label is provided in the second space formed between the shrink label and the container body at the packaging position. As a result, by using this label packaging, at least a portion of the tack label is present between the container body and the shrink label in the label packaging after thermal shrinkage.

Therefore, the tack label cannot be removed from the container body unless the shrink label is removed from the container body. This prevents the tack label from being peeled off from the container body at stores, etc., and therefore prevents theft of the tack label at stores, etc., and the fraudulent taking of campaign information printed on the tack label. In addition, the tack label can be kept reliably affixed in the designated position on the shrink label until it reaches the consumer.

In the label package according to aspect 2 of the present invention, in the above aspect 1, the tack label (11) has an attachment portion (11b) that is attached to the surface of the container body (101) and a non-attached portion (11c) that is not attached to the surface of the container body, and the tack label has a widthwise length that decreases from the non-attached portion side toward the attached portion side, and at least a portion of the non-attached portion is provided outside the second space (SP2), and at least a portion of the affixed portion is provided within the second space.

The tack label placed in the second space is sandwiched between the shrink label and the container body after the shrink label is thermally shrunk. Therefore, with the above configuration, the widthwise length of the affixed portion of the tack label that is sandwiched between the shrink label and the container body is shorter than the widthwise length of the non-affixed portion of the tack label that is not sandwiched between the shrink label and the container body. This makes it possible to shorten the circumferential length of the overlapping portion of the tack label and shrink label, thereby ensuring a printing area for the tack label while suppressing wrinkles in the shrink label after thermal shrinkage.

The labeled container (100) according to aspect 3 of the present invention is a labeled container comprising a container body (101), a shrink label (12) that is heat-shrunk onto the container body to package the container body, and a tack label (11) that can be affixed to the container body, in which the shrink label is rolled up before heat shrinking and affixed to the container body within a first space (SP1) that is formed to contain the container body, and at least a portion of the tack label is sandwiched between the shrink label and the container body.

According to the above configuration, the tack label is present within the first space formed when the shrink label is in a rolled state before thermal shrinkage. Therefore, even if the tack label is affixed to the container body before the thermal shrinkage process, the tack label does not prevent the shrink label from being placed in the specified packaging position. This allows the tack label to be affixed to the container before the shrink label is placed in the specified packaging position for thermal shrinkage.

In addition, since the tack label can be affixed to the container body before the shrink label is placed in the designated packaging position, the position of the shrink label can be aligned with the tack label when the shrink label is placed in the designated packaging position.

As a result, labeled containers can be automatically manufactured on the same conveyor line that performs shrink packaging, with the tack label aligned and affixed to the specified position on the shrink label.

In addition, at least a portion of the tack label is sandwiched between the container body and the shrink label. Therefore, the tack label cannot be removed from the container body unless the shrink label is removed from the container body. This prevents the tack label from being peeled off from the container body at stores, etc., and therefore prevents theft of the tack label at stores, etc., and the fraudulent taking of campaign information printed on the tack label. In addition, the tack label can be reliably kept attached in a designated position on the shrink label until it reaches the consumer.

The labeled container (100) according to aspect 4 of the present invention may be the same as that according to aspect 3 above, in which the tack label (11) is disposed at a predetermined position on the shrink label (12).

According to the above configuration, for example, if the specified position of the shrink label is near the product name, the consumer can recognize the tack label when checking the product name. Therefore, campaign information, etc. printed on the tack label can be reliably visually recognized by the consumer.

The labeled container (100) according to aspect 5 of the present invention is the container body (101) of aspect 3 or 4, which includes a mouth (14) for pouring out the contents, a shoulder (15) extending radially outward from the mouth, and a body (16) extending cylindrically from a circular bottom (17) to the shoulder, and the tack label may be attached to the shoulder.

According to the above configuration, the shrink label can be placed in the first space formed to contain the container body by simply attaching the tack label to the shoulder of the container body.

The manufacturing method of the labeled container (100) according to aspect 6 of the present invention includes a first step of attaching a tack label (11) to the container body (101) to be packaged in a first space (SP1) formed when rolling up the shrink label (12), a second step of rolling up the shrink label to place the tack label attached in the first step and the container body within the first space, and a third step of thermally shrinking the shrink label at a predetermined packaging position and sandwiching at least a portion of the tack label between the shrink label and the container body. The above configuration provides the same effect as aspect 3.

In the method for manufacturing a labeled container (100) according to aspect 7 of the present invention, in the above aspect 6, the position at which the tack label (11) is affixed in the first step may be a position that does not interfere with the trajectory (TR1) that the shrink label (12) follows when it is moved to the container body (101).

The above configuration makes it possible to suitably manufacture labeled containers when the shrink label is a cylindrical shrink label.

The present invention is not limited to the above-described embodiment, and various modifications are possible within the scope of the claims. Embodiments obtained by appropriately combining the technical means disclosed in the embodiments are also included in the technical scope of the present invention.
