Description

Technical Field

[0001] The present invention relates to the technical field of easy-tear stickers, in particular to an easy-tear sticker structure with a pattern layer and anti-counterfeiting function. Background Art

[0002] Sheet labels such as easy-to-tear stickers and sticky notes have become common adhesive objects in modern life, for example, used for sealing the mouth of a portable cup or labeling labels for documents, etc. Generally, commercially available sheet labels are stacked in a plurality of sheets to form a sheet label stack set. Figure 1 That is, a three-dimensional diagram of a conventional sheet label stack is shown. As is known to all, during single use, only one sheet label 11a needs to be torn off from the sheet label stack 1a at a time, and then the torn sheet label 11a is attached to an object to be attached.

[0003] Furthermore, in order to integrate more sheet labels into the same group to facilitate users' arbitrary selection and use, sheet label manufacturers use a cylindrical base to carry multiple sheet label stacks at the same time. Figure 2 That is, a perspective view of a conventional sheet label stack with a cylindrical base is shown, and, Figure 3 This is a three-dimensional diagram showing another perspective of a conventional sheet label stack with a cylindrical base. Figure 2 As shown, the plurality of stacks of sheet labels 1a are arranged on the side of the same cylindrical base 2a. It is worth noting that, due to process factors, the sides of any two adjacent stacks of sheet labels 1a arranged on the cylindrical base 2a are tied together. Figure 3 As shown, when a user tears off a single-piece label 11a from any single-piece label stack 1a, the user will often tear off the single-piece label 11a on the adjacent single-piece label stack 1a at the same time.

[0004] Furthermore, practical experience also indicates that when a user tears off a single-piece label 11a from any single-piece label stack group 1a, even if a single-piece label 11a on an adjacent single-piece label stack group 1a is not lifted up, part of its adhesive layer will be scraped off, causing the unused single-piece label 11a to eventually fall off the single-piece label stack group 1a to which it belongs. In particular, if the single-piece label 11a has confidentiality and / or anti-counterfeiting functions, the adjacent single-piece label 11a will be lifted up at the same time, and the tearing pattern will be displayed, and the label will be revealed prematurely, causing it to lose its confidentiality and / or anti-counterfeiting functions.

[0005] Therefore, we have learned from the above description the main defects of the existing sheet-type label stacking set with a cylindrical base. From the above description, it is necessary to redesign a sheet-type label stacking set with a cylindrical base so that it can have the functions of easy tearing, good sticking, no debonding, and confidentiality (anti-counterfeiting). Based on the above reasons, the inventor of this case has made great efforts to study and invent, and finally developed an easy-tear label structure with a pattern layer of the present invention. Summary of the invention

[0006] The first purpose of the present invention is to provide an easy-to-tear sticker structure with a pattern layer, which includes: a base and a plurality of easy-to-tear sticker units. According to the design of the present invention, each of the easy-to-tear sticker units includes a plurality of easy-to-tear stickers stacked on each other, and the plurality of easy-to-tear sticker units are arranged on a setting surface of the base. In particular, the design of the present invention allows any two adjacent easy-to-tear sticker units to have a spacing. With such a design, when a user tears off an easy-to-tear sticker from any easy-to-tear sticker unit, the easy-to-tear stickers on the adjacent easy-to-tear sticker units will not be affected in any way. Simply put, the special design of allowing any two adjacent easy-to-tear sticker units to have a spacing makes the easy-to-tear sticker with a pattern layer of the present invention have the advantages of being easy to tear, not debonding, and not showing traces prematurely.

[0007] The second objective of the present invention is to provide an easy-to-tear sticker structure with a pattern layer, and to specially design the structural composition of each easy-to-tear sticker so that the easy-to-tear sticker can display the functions of confidentiality and / or anti-counterfeiting in different forms.

[0008] In order to achieve the first and second objectives of the present invention, the inventors of the present invention provide a first embodiment (full rotation embodiment) of the easy-tear structure with a pattern layer, comprising:

[0009] A base having a setting surface; and

[0010] A plurality of easy-to-tear adhesive units are disposed on the mounting surface of the base, and any two adjacent easy-to-tear adhesive units have a spacing;

[0011] Each of the easy-to-tear sticker units includes a plurality of easy-to-tear stickers stacked on top of each other, and each of the easy-to-tear stickers includes:

[0012] a basal layer;

[0013] a pattern layer, covering an inner surface of the base layer, and having a first pattern and pattern gaps; wherein the first pattern is presented on the inner surface of the base layer;

[0014] a fixing color layer covering the pattern layer and comprising a first fixing color portion covering the first pattern and a second fixing color portion filling in the gaps between the patterns; and

[0015] an adhesive layer covering the fixing color layer;

[0016] A plurality of easy-to-tear sticking units are arranged on the arrangement surface of the base, and any two adjacent easy-to-tear sticking units have a distance therebetween.

[0017] In the first embodiment of the easy-tear structure with a pattern layer of the present invention, the base is a cylindrical base or a sheet-shaped base.

[0018] In the first embodiment of the easy-tear structure with a pattern layer of the present invention, the base layer has at least one extension section, so that the length of the base layer is greater than the lengths of the pattern layer, the fixing color layer, and the adhesive layer.

[0019] In the first embodiment of the easy-tear structure with a pattern layer of the present invention, the first pattern can be any of the following: words, letters, numbers, symbols, graphics, or a combination of any two or more of the above.

[0020] In the first embodiment of the easy-tear structure with a pattern layer of the present invention, the adhesion of the pattern layer to the first fixing color part of the fixing color layer is smaller than the adhesion of the base layer to the pattern layer, the adhesion of the pattern layer to the first fixing color part of the fixing color layer is also smaller than the adhesion of the adhesive layer to the first fixing color part of the fixing color layer, and the adhesion of the base layer to the second fixing color part of the fixing color layer is greater than the adhesion of the adhesive layer to the second fixing color part of the fixing color layer.

[0021] In the first embodiment of the easy-tear sticker structure with a pattern layer of the present invention, after a piece of the easy-tear sticker is attached to the surface of a sealed object and force is then applied to one end of the base layer to pull it upward, the adhesive layer will remain entirely on the surface of the sealed object, the first fixed color portion covering the first pattern will entirely adhere to the adhesive layer, and the pattern layer and the second fixed color portion filled in the gaps in the pattern will detach from the surface of the sealed object together with the base layer.

[0022] Furthermore, in a second embodiment (half-rotation embodiment) of the easy-tear structure with a pattern layer of the present invention, the adhesion of the fixing color layer to the base layer is greater than the adhesion of the fixing color layer to the pattern layer, and the adhesion of the adhesive layer to the fixing color layer is greater than the adhesion of the first fixing color portion of the fixing color layer to the pattern layer.

[0023] In the second embodiment of the easy-tear sticker structure with a pattern layer of the present invention, after a piece of the easy-tear sticker is attached to the surface of a sealed object and force is then applied to one end of the base layer to pull it upward, the adhesion of the adhesive layer to the sealed object will act on the fixed color layer, causing the fixed color layer to simultaneously exert a separation force on the pattern layer and the base layer, so that the first fixed color part of the fixed color layer and the pattern layer are pulled apart to form a gap.

[0024] Furthermore, in a third embodiment (non-rotating embodiment) of the easy-tear structure with a pattern layer of the present invention, the adhesion of the adhesive layer to the fixing color layer is greater than the adhesion of the first fixing color portion of the fixing color layer to the pattern layer, the adhesion of the adhesive layer to the fixing color layer is less than the adhesion of the fixing color layer to the base layer, and the adhesion of the fixing color layer to the base layer is greater than the adhesion of the first fixing color portion of the fixing color layer to the pattern layer.

[0025] In the third embodiment of the easy-tear sticker structure with a pattern layer of the present invention, after a piece of the easy-tear sticker is attached to the surface of a sealed object and force is then applied to one end of the base layer and it is pulled upward, a gap is generated between the first fixed color portion of the fixed color layer and the pattern layer, and the adhesive layer will not remain on the sealed object.

[0026] The advantage is that when a user tears off a tear-off sticker from any tear-off sticker unit, the tear-off stickers on the adjacent tear-off sticker units will not be affected, achieving the advantages of easy tearing, no debonding, and no early revealing. At the same time, the present invention also specially designs the structure of the tear-off sticker, so that each tear-off sticker can display the confidentiality and / or anti-counterfeiting effect in different forms.

DETAILED DESCRIPTION

[0044] In order to more clearly describe the easy-tear structure 1 with a pattern layer proposed by the present invention, the preferred embodiment of the present invention will be described in detail below with reference to the drawings.

[0045] First embodiment (full rotation embodiment)

[0046] The first embodiment of the present invention described below is a full transfer embodiment, which means that when the privacy peelable label is torn off, words or patterns will appear on the base layer of the peelable label, and the adhesive layer of the peelable label will be transferred to the sealed object.

[0047] See also Figure 4A and Figure 4B , which are the first and second stereoscopic images of an easy-tear structure 1 with a pattern layer of the present invention.

[0048] The easy-to-tear structure 1 with a pattern layer of the present invention comprises: a base 10 and a plurality of easy-to-tear units EU, wherein the plurality of easy-to-tear units EU are disposed on a disposition surface of the base 10. For example, Figure 4A The base 10 is shown to be a cylindrical base, and the setting surface is the annular side surface of the base 10; on the other hand, Figure 4B The base 10 is a sheet-shaped base, and the setting surface is the surface of the base 10. According to the design of the present invention, each easy-to-tear sticker unit EU includes a plurality of easy-to-tear stickers 11 stacked on each other, and any two adjacent easy-to-tear sticker units EU have a spacing D. With such a design, when a user tears off an easy-to-tear sticker 11 from any easy-to-tear sticker unit EU, the easy-to-tear sticker 11 on the adjacent easy-to-tear sticker unit EU will not be affected in any way. In short, the special design of making any two adjacent easy-to-tear sticker units EU have a spacing D makes the easy-to-tear sticker structure 1 with a pattern layer of the present invention have the advantages of easy tearing, no debonding, and no premature traces.

[0049] See also Figure 5 , which shows a cross-sectional view of an easy-to-tear sticker of the present invention. Figure 5 As shown, each easy-to-tear sticker 11 in the easy-to-tear sticker unit EU includes: a base layer 111, a pattern layer 112, a fixing color layer 113, and an adhesive layer 115. On the other hand, Figure 6 A three-dimensional diagram showing an easy-tear sticker and a sealed object of the present invention, and Fig. 7A and Figure 7B A schematic flow chart showing the process of peeling the easy-tear sticker from the sealed object. Figure 5 and Figure 7BAs shown, the pattern layer 112 is coated on an inner surface of the base layer 111 and has a first pattern 118 and a pattern gap 116. On the other hand, the fixed color layer 113 is coated on the pattern layer 112 and includes a first fixed color portion 113a coated on the first pattern 118 of the pattern layer 112 and a second fixed color portion 113b filled in the pattern gap 116 of the pattern layer 112. For example, if the fixed color layer 113 is a red pigment layer, the first pattern 118 will display red because it is coated with red pigment (that is, the first fixed color portion 113a). Of course, in actual applications, the fixed color layer 113 can also be a multi-color pigment layer, and is not limited to a single-color pigment layer.

[0050] Furthermore, the adhesive layer 115 is coated on the fixing color layer 113. It is particularly emphasized that in the first embodiment of the easy-tear structure 1 with a pattern layer of the present invention, the adhesion of the pattern layer 112 to the first fixing color part 113a of the fixing color layer 113 is less than the adhesion of the base layer 111 to the pattern layer 112, the adhesion of the pattern layer 112 to the first fixing color part 113a of the fixing color layer 113 is also less than the adhesion of the adhesive layer 115 to the first fixing color part 113a of the fixing color layer 113, and the adhesion of the base layer 111 to the second fixing color part 113b of the fixing color layer 113 is greater than the adhesion of the adhesive layer 115 to the second fixing color part 113b of the fixing color layer 113.

[0051] Depend on Figure 5 and Figure 6 It can be seen that the base layer 111 has at least one extension section 111E, so that the length of the base layer 111 is greater than the lengths of the pattern layer 112, the fixing color layer 113, and the adhesive layer 115. Fig. 7A As shown in FIG. 1 , after a piece of the easy-tear sticker 11 is attached to the surface of a sealed object 2, the user can selectively hold the extension section 111E and apply force to one end of the base layer 111 and pull it upward, thereby completing the tearing process of the easy-tear sticker 11. Figure 7BAs shown, after the peeling process of the easy-tear label 11 is completed, it can be found that the adhesive layer 115 is completely left on the surface of the sealed object 2, and the first fixed color portion 113a covering the first pattern 118 is also completely adhered to the adhesive layer 115. The main reason for such a result is that the first embodiment of the present invention is specially designed so that the adhesion of the pattern layer 112 to the first fixing color part 113a of the fixing color layer 113 is smaller than the adhesion of the base layer 111 to the pattern layer 112, and the adhesion of the pattern layer 112 to the first fixing color part 113a of the fixing color layer 113 is also smaller than the adhesion of the adhesive layer 115 to the first fixing color part 113a of the fixing color layer 113, and the adhesion of the base layer 111 to the second fixing color part 113b of the fixing color layer 113 is greater than the adhesion of the adhesive layer 115 to the second fixing color part 113b of the fixing color layer 113. And, as Fig. 7A and Figure 7B As shown, after the peeling process of the easy-tear sticker 11 is completed, the pattern layer 112 and the second fixed color portion 113b filled in the pattern gap are separated from the surface of the sealed object 2 together with the base layer 111.

[0052] Please continue reading Figure 8 , which shows the top view of the base layer. As known from the above description, after the peeling process of the easy-to-peel sticker 11 is completed, the pattern layer 112 and the second fixed color portion 113b filled in the pattern gap 116 will also be separated from the surface of the sealed object 2 along with the base layer 111. It is worth noting that the base layer 111 is a plastic sheet, and the first pattern 118 of the pattern layer 112 is presented on the inner surface of the base layer 111; therefore, when viewing the top view of the base layer 111, it will appear as follows: Figure 8 shown.

[0053] Continue reading Figure 7B , and please also refer to Fig. 9 As can be seen from the above description, after the peeling process of the easy-to-peel sticker 11 is completed, the first fixed color portion 113a originally covering the pattern layer 112 will be completely adhered to the adhesive layer 115. At this time, the adhesive layer 115 can be viewed from the top view as shown in FIG. Fig. 9 As shown. It is easy to infer that although Figure 8 and Fig. 9 The patterns used to demonstrate the anti-counterfeiting function are all "Void" characters, but this is only an exemplary embodiment and is not intended to limit the actual state of the pattern. In possible applications, the pattern (first pattern 118) can be text, letters, numbers, symbols, graphics, or any combination of two or more of the above.

[0054] Second embodiment (half-turn embodiment)

[0055] The second embodiment of the present invention described below is a half-rotation embodiment, which means that when the privacy peelable label is torn off, words or patterns will appear on the base layer of the peelable label, and half of the adhesive layer of the peelable label will be transferred to the sealed object, while the other half will not be transferred to the sealed object.

[0056] Please continue Figure 4A and Figure 4B The second embodiment of the easy-tear structure 1 with a pattern layer of the present invention also includes a base 10 and a plurality of easy-tear units EU, wherein each of the easy-tear units EU includes a plurality of easy-tear sheets 11 stacked on each other, and any two adjacent easy-tear units EU have a distance D.

[0057] Further, Fig.10 A cross-sectional view showing a second embodiment of an easy-tear sticker of the present invention, and Fig.11 The sectional view of the easy-tear sticker after use is shown. It is particularly noted that the second embodiment of the easy-tear sticker 11 is based on the structure of the first embodiment and is appropriately adjusted. At the same time, it must be explained in advance that the so-called "after use" refers to the easy-tear sticker 11 being attached to the surface of a sealed object 2 (refer to Figure 6 As shown), and then is torn off the surface of the sealed object 2. Fig.11 What is shown is a cross-sectional view of the surface of the sealed object 2 after the easy-tear sticker 11 is torn off and then stuck back.

[0058] like Fig.10 and Fig.11 As shown, the second embodiment of the easy-to-peel sticker 11 includes: a base layer 111, a pattern layer 112, a fixing color layer 113, and an adhesive layer 115; wherein the pattern layer 112 is coated on an inner surface of the base layer 111, and has a first pattern 118 and a pattern gap 116. Moreover, the fixing color layer 113 is coated on the pattern layer 112, and includes a first fixing color portion 113a coated on the first pattern 118 of the pattern layer 112 and a second fixing color portion 113b filled in the pattern gap 116 of the pattern layer 112.

[0059] In the second embodiment, the adhesion of the fixing color layer 113 to the base layer 111 is greater than the adhesion of the fixing color layer 113 to the pattern layer 112, and the adhesion of the adhesive layer 115 to the fixing color layer 113 is greater than the adhesion of the first fixing color portion 113a of the fixing color layer 113 to the pattern layer 112. With such a design, after a piece of the easy-tear label 11 is attached to the surface of a sealed object 2, the user can apply force to one end of the base layer 111 and pull it upward, and optionally, the user can hold the extension section 111E of the base layer 111 and apply force to the base layer 111 to pull it upward, thereby completing the tearing process of the easy-tear label 11. However, during the process of tearing off the easy-tear label 11, the adhesion of the adhesive layer 115 to the sealed object 2 will act on the fixing color layer 113, so that the fixing color layer 113 simultaneously exerts a force to separate the pattern layer 112 and the base layer 111; at this time, since the adhesion of the fixing color layer 113 to the base layer 111 is greater than the adhesion of the fixing color layer 113 to the pattern layer 112, the first fixing color portion 113a of the fixing color layer 113 and the pattern layer 112 are pulled apart to form a gap 114, while the first fixing color portion 113b of the fixing color layer 113 and the base layer 111 are still in close contact.

[0060] Please continue reading Fig.12 , which shows the top view of the base layer of the easy-to-tear sticker. From the surface view of the base layer 111, and with Fig.11 As shown in FIG. 1 , the first pattern 118 of the pattern layer 112 is revealed by the gap 114. Therefore, when the upper view of the base layer 11 is viewed, the words displayed through the gap 114 are, for example, "Void" or "opened" and other words having a confidentiality effect. In this case, even if the peelable sticker 11 that has been torn off is pasted back on the sealed object 2 (such as Fig.11 It is also difficult to conceal the fact that the easy-tear sticker 11 has been torn off.

[0061] The third embodiment (non-transfer embodiment)

[0062] The third embodiment of the present invention described below is a non-transferring embodiment, which means that when the confidentiality tear-off label is torn off, words or patterns will appear on the base layer of the tear-off label, but the adhesive layer of the tear-off label will not be transferred to the sealed object.

[0063] Please continue Figure 4A and Figure 4BThe third embodiment of the easy-tear structure 1 with a pattern layer of the present invention also includes a base 10 and a plurality of easy-tear units EU, wherein each of the easy-tear units EU includes a plurality of easy-tear sheets 11 stacked on each other, and any two adjacent easy-tear units EU have a distance D.

[0064] Fig.13 A cross-sectional view showing a third embodiment of an easy-to-tear sticker of the present invention, and Fig.14A and Fig. 14B The schematic flow chart of peeling the easy-tear sticker from a sealed object is shown. According to the design of the present invention, the third embodiment of the easy-tear sticker 11 is based on the structure of the first embodiment and is appropriately adjusted.

[0065] like Fig.13 , Fig.14A and Fig. 14B As shown, the third embodiment of the easy-to-peel sticker 11 includes: a base layer 111, a pattern layer 112, a fixing color layer 113, and an adhesive layer 115; wherein the pattern layer 112 is coated on an inner surface of the base layer 111, and has a first pattern 118 and a pattern gap 116. Moreover, the fixing color layer 113 is coated on the pattern layer 112, and includes a first fixing color portion 113a coated on the first pattern 118 of the pattern layer 112 and a second fixing color portion 113b filled in the pattern gap 116 of the pattern layer 112. In particular, in the third embodiment, the adhesion of the adhesive layer 115 to the fixing color layer 113 is greater than the adhesion of the first fixing color portion 113a of the fixing color layer 113 to the pattern layer 112, the adhesion of the adhesive layer 115 to the fixing color layer 113 is less than the adhesion of the fixing color layer 113 to the base layer 111, and the adhesion of the fixing color layer 113 to the base layer 111 is greater than the adhesion of the first fixing color portion 113a of the fixing color layer 113 to the pattern layer 112.

[0066] like Fig.14AAs shown, after a piece of the easy-tear label 11 is attached to the surface of a sealed object 2, the user can apply force to one end of the base layer 111 and pull it upwards. Optionally, the user can hold the extension section 111E of the base layer 111 and pull the base layer 111 upwards, thus completing the tearing process of the easy-tear label 11. During the tearing process, since the adhesion of the adhesive layer 115 to the fixing color layer 113 is greater than the adhesion of the fixing color layer 113 to the pattern layer 112 and the adhesion of the adhesive layer 115 to the fixing color layer 113 is less than the adhesion of the fixing color layer 113 to the base layer 111, after the easy-tear label 11 is torn off, a gap 114 that cannot be reconstructed is formed between the first fixing color portion 113a of the fixing color layer 113 and the pattern layer 112. It is worth noting that, since the adhesion of the adhesive layer 115 to the fixing color layer 113 is less than the adhesion of the fixing color layer 113 to the base layer 111 and the adhesion of the fixing color layer 113 to the base layer 111 is greater than the adhesion of the fixing color layer 113 to the pattern layer 112, after the easy-tear label 11 is torn off, the adhesive layer 115 will not remain on the sealed object 2.

[0067] Please continue reading Fig.15 , which shows the top view of the base layer of the easy-tear sticker. After the easy-tear sticker 11 is torn off, no adhesive layer 115 will remain on the sealed object 2, so there is no need to clean the sealed object 2. Fig.15 As shown, the easy-tear sticker 11 can be pasted back onto the sealed object 2 to be used as an adhesive tape, but still maintains the torn appearance. Fig. 14B As shown, the first pattern 118 of the pattern layer 112 is revealed by virtue of the gap 114, so that the viewing Fig.15 When the base layer 111 is viewed from above, it is, for example, text such as "Void" or "Opened" that has a confidentiality effect.

[0068] The above description is only illustrative rather than restrictive of the present invention. Those skilled in the art will understand that many modifications, changes or equivalents may be made without departing from the spirit and scope defined by the claims, but all will fall within the scope of protection of the present invention.

4. The easy-to-tear structure with a pattern layer according to claim 1, characterized in that: The first pattern is any one of words, letters, numbers, symbols, and graphics, or a combination of any two or more of the above.

5. The easy-to-tear structure with a pattern layer according to claim 4, characterized in that: The adhesion of the pattern layer to the first fixing color part of the fixing color layer is smaller than the adhesion of the base layer to the pattern layer, the adhesion of the pattern layer to the first fixing color part of the fixing color layer is also smaller than the adhesion of the adhesive layer to the first fixing color part of the fixing color layer, and the adhesion of the base layer to the second fixing color part of the fixing color layer is greater than the adhesion of the adhesive layer to the second fixing color part of the fixing color layer.

6. The easy-to-tear structure with a pattern layer according to claim 5, characterized in that: After a piece of the easy-tear label is attached to the surface of a sealed object and force is then applied to one end of the base layer to pull it upward, the adhesive layer will remain entirely on the surface of the sealed object, the first fixed color portion covering the first pattern will entirely adhere to the adhesive layer, and the pattern layer and the second fixed color portion filled in the gaps between the patterns will detach from the surface of the sealed object along with the base layer.

7. The easy-to-tear structure with a pattern layer according to claim 4, characterized in that: The adhesion of the fixing color layer to the base layer is greater than the adhesion of the fixing color layer to the pattern layer, and the adhesion of the adhesive layer to the fixing color layer is greater than the adhesion of the first fixing color part of the fixing color layer to the pattern layer.

8. The easy-to-tear structure with a pattern layer according to claim 7, characterized in that: After a piece of the easy-tear label is attached to the surface of a sealed object and force is then applied to one end of the base layer to pull it upward, the adhesion of the adhesive layer to the sealed object will act on the fixed color layer, causing the fixed color layer to simultaneously exert a force to separate the pattern layer and the base layer, so that the first fixed color part of the fixed color layer is pulled apart from the pattern layer to form a gap.

9. The easy-to-tear structure with a pattern layer according to claim 4, characterized in that: The adhesion of the adhesive layer to the fixing color layer is greater than the adhesion of the first fixing color portion of the fixing color layer to the pattern layer, the adhesion of the adhesive layer to the fixing color layer is less than the adhesion of the fixing color layer to the base layer, and the adhesion of the fixing color layer to the base layer is greater than the adhesion of the first fixing color portion of the fixing color layer to the pattern layer.

10. The easy-to-tear structure with a pattern layer according to claim 9, characterized in that: After a piece of the easy-tear sticker is attached to the surface of a sealed object and force is then applied to one end of the base layer to pull it upward, a gap is generated between the first fixed color part of the fixed color layer and the pattern layer, and the adhesive layer will not remain on the sealed object.
