Heat-sublimable glitter film

Abstract

A heat-sublimation glitter film material comprises: a base layer, on which sequentially are an adhesive layer, a layered heat-resistant component, and a glitter layer, the layered heat-resistant component being able to withstand high temperatures; the glitter layer is formed of glitter powder, each glitter powder having an outer surface, the two outer surfaces being made of polyester. Wherein, when heat-sublimation ink is sublimated onto the glitter layer of the glitter film material, the heat-sublimation ink bonds with the polyester on the outer surface of the glitter powder, making the heat-sublimation ink saturated and vivid, giving the pattern of the heat-sublimation ink a bright and glossy color. This glitter film material is suitable for the public to create heat-sublimation patterns.

Description

Technical Field

[0001] This invention relates to a film material, specifically a glitter film material capable of heat-sublimation patterns, allowing users to easily create heat-sublimation patterns on the glitter film material, and enabling the heat-sublimation ink sublimated onto the glitter film material to have vibrant colors. Prior Technology

[0002] Please refer to Figure 19, which shows the plain glitter lettering film 90 and the glitter lettering film 100 with pattern 108 that are currently sold on the market. Consumers can cut out graphics from the lettering film 90 and 100 and stick the graphics on their clothes. Through the glitter powder, the graphics have a shiny effect.

[0003] The patternless glitter lettering film 90, as shown in Figure 20, has a hot melt adhesive layer 92 and a glitter layer 94. The glitter layer 94 is formed from glitter powder. The molding process involves applying adhesive to the hot melt adhesive layer, then sprinkling glitter powder onto the adhesive, causing the glitter powder to adhere to the hot melt adhesive layer 92. A removable film 96 is attached to the glitter layer 94. The user cuts out a pattern from the hot melt adhesive layer 92 and the glitter layer 94, places the cut pattern on clothing, and applies heat to the pattern, causing the hot melt adhesive layer 92 to become sticky, thus adhering the pattern to the clothing.

[0004] The patterned glitter lettering film 100, as shown in Figure 21, also has a hot melt adhesive layer 102, a glitter layer 104, and a thin film 106 attached to and separable from the glitter layer 104. The glitter layer 104 is formed of glitter powder. The surface of the glitter layer 104 also has a pattern 108 formed by thermal sublimation ink.

[0005] Figure 22 illustrates the method of creating a pattern 108 on the glitter layer 104 of the lettering film 100. First, the semi-finished product of the lettering film has a hot melt adhesive layer 102, a glitter layer 104, and a release paper 107. The hot melt adhesive layer 102 is attached to the release paper 107. The semi-finished product also has a sublimation paper 109 on which the pattern 108 is printed with sublimation ink. The sublimation paper 109 is brought into contact with the glitter layer 104, and a high temperature of 180°C or higher is applied to the semi-finished product using a heat press or iron, causing the sublimation ink of the pattern 108 to sublimate onto the glitter layer 104. After the pattern 108 has been sublimated, the release paper 107 is separated from the hot melt adhesive layer 102, and then a separable film 106 is attached to the glitter layer 104, thus producing the glitter lettering film 100 of Figure 21.

[0006] The existing glitter lettering films 90 and 100 present considerable inconvenience and shortcomings for both consumers and manufacturers. Firstly, existing glitter lettering films do not allow consumers to create patterns, due to the fabrication process of the pattern 108. As mentioned earlier, the pattern 108 is sublimated from the glitter layer 104 using sublimation paper 109. During the heat treatment of this semi-finished product, the hot melt adhesive 102 melts. Therefore, a release paper 107 must be adhered to the hot melt adhesive layer 102 to maintain its integrity and prevent the melted adhesive from sticking to other objects. After the pattern 108 has completed sublimation, the release paper 107 is separated from the hot melt adhesive layer 102. Patterned glitter lettering films 100, when sold, do not include the release paper 107.

[0007] However, after the pattern 108 is thermally sublimated, the hot melt adhesive 102 adheres to the release paper, with a peel force as high as 200-300 grams per inch of width. This means the release paper 107 is difficult to separate from the hot melt adhesive layer 102, making it suitable only for peeling in the factory and not for consumers to do themselves. This is especially true for small, pre-cut graphics, where consumers find it extremely difficult to separate the release paper 107 from the hot melt adhesive layer 102. The high peel force between the hot melt adhesive layer 102 and the release paper 107 makes peeling difficult, often resulting in damage to the lettering film and the pattern 108, even in the factory. Due to this difficulty, existing patterned glitter lettering films 100 undergo thermal sublimation of the pattern 108 and peeling of the release paper 107 at the factory, preventing consumers from creating graphics and peeling the release paper themselves.

[0008] Furthermore, when the pattern 108 is heat-sublimated onto the lettering film 100, the adhesive of the hot melt adhesive layer 102 will penetrate the glitter layer 104 and adhere to the heat-sublimation paper 109, causing the heat-sublimation paper to stick to the lettering film. This is one of the reasons why it is not suitable for consumers to create heat-sublimation patterns on existing glitter lettering films themselves.

[0009] Therefore, the glitter lettering films available on the market are divided into two categories: patterned and unpatterned. Patterned glitter lettering films 100 have patterns 108 pre-made at the manufacturing stage (Figure 19 shows only one pattern). The glitter lettering films 100 purchased by consumers already have patterns 108. However, only a small portion of consumers want the pre-made patterns 108. In order to increase market share, manufacturers produce many different styles of lettering films 100. Consumers are forced to choose from a large number of patterns of lettering films that they can accept but do not really like.

[0010] The plain glitter lettering film 90 consists of a single-color glitter layer 92. To provide consumers with choices and purchasing opportunities, manufacturers will produce a variety of different colored lettering films 90 for consumers to choose from.

[0011] The existing glitter lettering films 90 and 100 have several unresolved problems. On the consumer side, consumers cannot create their own designs on the film; if they want designs, they can only accept pre-designed films. On the manufacturing side, manufacturers must produce a variety of styles (patterns or colors) of glitter lettering films 90 and 100 for consumers to choose from, and they need ample space for sales, display, and storage. However, only two or three out of a hundred designs may be bestsellers; the vast majority of designs are slow-moving, difficult to recycle, and ultimately have to be destroyed, resulting in resource waste.

[0012] Existing glitter powders use aluminum to produce color. An aluminum layer is coated onto a polyester (PET) film, followed by coloring to change the film's color. This PET film is then cut into glitter powder to create different colors. Alternatively, coated films can be cut into rainbow glitter powder, which reflects or refracts light in a rainbow pattern.

[0013] When the sublimation ink on the sublimation paper is sublimated onto the existing silver glitter layer 104, some of the ink bonds with the aluminum content of the glitter powder, while some bonds with the polyester surface of the glitter powder. This results in unsaturated ink and loss of vibrancy, making the pattern 108 on the glitter lettering film 100 appear dull, lacking luster, and indistinct. Similarly, when the sublimation ink bonds with iridescent glitter powder, the ink color also appears dull, lacking luster, and indistinct. Current technology cannot produce vibrant sublimation patterns. Summary of the Invention

[0014] Through the inventor's painstaking research, this invention solves the aforementioned problems. One objective of this invention is to provide a heat-sublimation glitter film material on which heat-sublimation patterns can be created. The heat-sublimation glitter film material of this invention is particularly suitable for allowing users to create various heat-sublimation patterns.

[0015] One objective of this invention is to provide a glitter film material that can be thermally sublimated, so that thermally sublimated ink can sublimate into a bright color on the glitter film material.

[0016] One objective of this invention is to provide a glitter film material that can be thermally sublimated, the glitter film material having an adhesive layer and a base layer, the invention being to make the adhesive layer and the base layer have a low peel force, making them easy to separate.

[0017] One objective of this invention is to provide a glitter film material that can be thermally sublimated, which can prevent the adhesive layer of the film material from sticking to the thermal sublimation paper and becoming difficult to separate when making thermal sublimation patterns.

[0018] One objective of this invention is to provide a glitter film material that can be thermally sublimated, which can reduce the variety of glitter film materials sold and displayed, reduce inventory and manufacturing quantity, and be more environmentally friendly.

A layered heat-resistant component is disposed on the adhesive layer, and the layered heat-resistant component can withstand temperatures higher than those that cause the adhesive layer to become sticky when heated; A glitter layer, comprising glitter powder, is disposed on the high-temperature layer assembly. Each glitter powder has an outer surface, and the two outer surfaces are entirely made of polyester material.

[0020] Therefore, the outer surface of the glitter powder is made of polyester.

The pattern of the sublimation ink has bright and shiny colors.

[0021] When the pattern is thermally sublimated onto the glitter film, the layered heat-resistant component can block the adhesive of the adhesive layer, preventing the adhesive from reaching the glitter layer, making it easy for the glitter film to separate from the thermal sublimation paper of the thermal sublimation ink.

The inner layer is made of a material that can produce iridescent light, making the glitter layer a rainbow glitter layer, where the reflected or refracted light is iridescent (multicolored).

[0025] Preferably, the glitter powder is a transparent glitter powder.

[0026] Preferably, after the adhesive layer becomes sticky when heated, the peel force between it and the substrate is between 20 grams and 150 grams per inch, making the adhesive layer easy to peel from the substrate. More preferably, the peel force is between 20 grams and 100 grams per inch, or between 20 grams and 80 grams per inch.

[0027] Preferably, the layered heat-resistant component is a high-temperature barrier layer capable of withstanding temperatures above 170°C. Preferably, the high-temperature barrier layer is made of high-temperature resistant thermoplastic polyurethane or polyurethane material.

According to the inventors' actual tests, the adhesive layer using these materials has a peel strength of 20 grams to 100 grams per inch width, making it easy to peel off. Simple Explanation of the Diagram

[0031] The purpose, features, and effects of this invention can be understood from the following description and drawings of preferred embodiments, wherein: Figure 1 is a cross-sectional schematic diagram of a thermally sublimable glitter film material according to a preferred embodiment of the present invention. Figures 2A to 2C show enlarged cross-sectional views of the three types of glitter powders of the present invention. The glitter powders in Figures 2A and 2B are made by cutting the glitter material film in Figures 3A and 3B. Figures 3A and 3B are cross-sectional schematic diagrams of the two-film glitter materials developed by the inventors of this case. Figure 4 is a photograph of a thermally sublimable glitter film material according to a preferred embodiment of the present invention. Figures 5 to 15 show the manufacturing process of forming a pattern printed with sublimation ink onto fabric using the glitter film material of the present invention. Figure 9 shows a cross-sectional schematic diagram of the glitter layer of the glitter film material where the sublimation ink is sublimated. Figure 16 shows a sublimation pattern made on fabric using the glitter film material of the present invention. Figures 17 and 18 show two sublimation patterns formed on fabric using the glitter film material of the present invention. Figure 19 shows two common types of glitter lettering films. Figure 20 is a cross-sectional view of a conventional plain glitter lettering film. Figure 21 is a cross-sectional view of a conventional patterned glitter engraving film. Figure 22 is a cross-sectional view of the semi-finished patterned glitter lettering film of Figure 21, showing the method of making the patterned glitter lettering film. Implementation

[0032] Please refer to Figure 1, which shows the heat-sublimable glitter film material 10 provided in the first preferred embodiment of the present invention. It includes: a base layer 20, an adhesive layer 30, a layered heat-resistant component 40 and a glitter layer 50 stacked together. The glitter layer is an outer layer of the glitter film material and serves as a glitter surface. Users can create heat-sublimation patterns on the glitter layer 50 of the glitter film material 10.

[0033] The base layer 20 is a release-type carrier, which can be a release film or release paper.

[0034] The adhesive layer 30 is disposed on one surface of the base layer 20. In this invention, after the adhesive layer 30 is subjected to high temperature and becomes sticky, the peel force between the adhesive layer 30 and the base layer 20 is between 20 grams and 150 grams per 1 inch width, preferably between 20 grams and 100 grams, and more preferably between 20 grams and 80 grams. The test condition for this peel force is: the adhesive layer 30 and the base layer 20 are bonded together into a strip with a width of 1 inch, and the two are pulled in opposite directions; this is the force that can separate the two. Therefore, after the glitter film material 10 is heated, the adhesion and peel force between the adhesive layer 30 and the base layer 20 are low, and the two 30 and 20 are easily separated. In this preferred embodiment, the adhesive layer 30 is a hot melt adhesive from the ethylene-vinyl acetate copolymer (EVA) series. It is solid at room temperature and melts when heated, becoming a viscous liquid adhesive (hot melt adhesive). This EVA hot melt adhesive layer 30 is polarized, making it easy to separate from the base layer 20 after it becomes viscous. The adhesive layer 30 can use pressure-sensitive adhesive (PSA) (also known as self-adhesive), polarized thermoplastic polyurethane (TPU), or polarized polyphenylene ether (PES) hot melt adhesive. Based on the inventor's fabrication and testing, the peel force between the adhesive layer using these materials and the base layer 20 is between 20 grams and 150 grams per inch of width. After the EVA hot melt adhesive layer becomes viscous when heated, the peel force between it and the base layer 20 is 20-100 grams per inch of width, making it easy to separate. After the PES hot melt adhesive becomes viscous when heated, its peel strength with the substrate 20 is 20~100 grams per inch of width.

[0035] The layered heat-resistant component 40 is disposed on the adhesive layer 30 to isolate high temperature and the adhesive layer 30, preventing the adhesive of the adhesive layer 30 from passing through the layered heat-resistant component 40 and from seeping into the glitter layer 50. Preferably, the layered heat-resistant component 40 can withstand high temperatures above 180°C, more preferably, it can withstand high temperatures above 210°C, for example, 215~225°C.

[0036] In this preferred embodiment, the layered durable component 40 includes: a high-temperature barrier layer 42 and an adhesive layer 44. The high-temperature barrier layer 42 is a layer of thermoplastic polyurethane (TPU) that can withstand high temperatures. The adhesive layer 44 is an adhesive made of polyurethane (PU). The high-temperature barrier layer 42 is disposed on one surface of the adhesive layer 30, and the adhesive layer 44 is disposed on one surface of the high-temperature barrier layer 42 by coating or bonding. Once the adhesive layer 44 has set, it will no longer react or become sticky when heated.

[0037] The glitter layer 50 is formed by a layer of glitter powder. Tiny, fine glitter powder is evenly sprinkled and adhered to the adhesive layer 44 to form the glitter layer 50. For example, the adhesive layer 44 in liquid form is coated onto the high-temperature barrier layer 42, and the glitter powder is sprinkled onto the adhesive layer 44, then excess glitter powder is cleaned off. Figures 2A to 2C show three types of glitter powder 52, 52A, and 52B of the present invention. The size of each glitter powder 52, 52A, or 52B particle is, for example but not limited to, 1 / 128 inch to 1 / 256 inch in this embodiment. The glitter powder 52 or 52A of the present invention is made from fine particles cut from the glitter material films 60 and 60A shown in Figures 3A and 3B, and is formed in a square or hexagonal shape. These two glitter material films 60 and 60A were invented by the inventors of the present invention. The glitter film 60 has two outer layers 62 and at least one inner layer 64. The two outer layers 62 are made of transparent polyester (PET), while the inner layer 64 contains a metallic material, such as an aluminum or silver layer. Fine glitter powder 52 is cut from the glitter film 60. The glitter powder 52 forms a sandwich structure, having two transparent polyester outer layers 54 and an inner layer 55, which is formed from the inner layer 64 of the glitter film 60. For example, the glitter powder 52 is silver glitter powder, with its inner layer 55 plated with silver, while its two outer layers 54 are both polyester. The inner layer 55 gives the glitter powder its silver color.

[0038] The glitter film 60A has two outer layers 62 and at least one inner layer 65. The two outer layers 62 are made of transparent polyester, while the inner layer 65 is a polymer film capable of producing rainbows. For example, the polymer film has one or more coatings, causing the light it refracts or reflects to be rainbow-colored, achieving a rainbow visual effect. The inner layer 65 can also be a polymer film with zinc sulfide material, which can produce a rainbow visual effect. Fine glitter powder 52A is cut from the glitter film 60A. The glitter powder 52A has a sandwich structure, having two transparent polyester outer layers 54 and an inner layer 56. The inner layer 56 is formed from the inner layer 65 of the glitter film 60A, making the glitter powder 52A a transparent rainbow glitter powder. Through the inner layer 56, the light refracted or reflected by the glitter powder 52A has a rainbow (multicolored) visual effect.

[0039] The glitter powder 52B shown in Figure 2C is made by cutting a layer of transparent polyester material, resulting in a transparent glitter powder with transparency.

[0040] The two outer surfaces 57 of the glitter powder 52, 52A, or 52B of this invention are all made of polyester, with no other materials besides polyester. Specifically, the cross-section of the glitter powder 52 or 52A is rectangular, with a pair of outer surfaces 57 located on opposite sides and a pair of cut surfaces 58. The two outer surfaces 57 are formed by the two outer layers 54, therefore, the two outer surfaces 57 are entirely made of polyester, with no other materials. The area of ​​the two cut surfaces 58 of the glitter powder 52 is mainly made of polyester, with only a small area of ​​the inner layer 55. Similarly, the two cut surfaces 58 of the glitter powder 52A are mainly made of polyester, with only a small area of ​​each cut surface 58 being the area of ​​the inner layer 56. The two outer surfaces 57 and the two cut surfaces 58 of the glitter powder 52B are entirely made of polyester, with no other materials.

[0041] Figure 4 is a photograph of the glitter film material 10 of a preferred embodiment of the present invention, the outermost surface of which is the glitter layer, densely covered with glitter powder 52.

[0042] The following describes the process of using the glitter film material 10 of the present invention in conjunction with sublimation paper to sublimate text or non-text patterns onto a fabric (e.g., clothing). The adhesive layer 30 of the film material is EVA hot melt adhesive as an example.

[0043] Please refer to Figure 5. The user uses a home printer 70 to print a colored pattern 74 onto a sublimation paper 72 using sublimation ink. The pattern can be text (such as the English letters A, B, C) or non-text (such as people, landscapes, objects, symbols, etc.). The pattern in Figure 5 is an example of a snowman.

[0044] Please refer to Figure 6. Take a glitter film 10 of the present invention and a strip of sublimation paper 72 printed with a pattern 74 and overlap them together. The pattern is in contact with the glitter layer of the glitter film 10. Then, heat the two together with a heat press machine 77 or an iron, as shown in Figure 7, for example, at a temperature of 205°C for 60 seconds.

[0045] After heat treatment as shown in Figure 7, the sublimation ink on the sublimation paper 72 sublimates onto the glitter layer 50 of the glitter film 10. As shown in Figure 8, when the sublimation paper 72 is separated from the glitter film 10, it can be seen that the ink of the pattern 74 sublimates onto the glitter layer 50. Referring to Figure 9, the sublimation ink of the sublimation pattern 74 is bonded to a polyester surface (i.e., outer surface) 57 of the glitter powder 52. Figure 10 shows another glitter film 10 of the present invention, which has another colored sublimation pattern 74A on the glitter layer 50.

[0046] Next, as shown in Figure 11, a pattern 76 is cut from the outline of the pattern 74 using a household cutting machine 78. The cutting depth D of the blade, as shown in Figure 9, cuts off the glitter layer 50, the adhesive layer 44, the high-temperature barrier layer 42, and the adhesive layer (hot melt adhesive layer) 30. After cutting, the waste material W other than the pattern 76 is removed, as shown in Figures 12 and 9, leaving only the pattern 76 on the glitter film material 10.

[0047] Next, as shown in Figure 13, a transfer film 79 is attached to the pattern 76, and the pattern 76 is separated from the base layer 20 of the glitter film material 10, as shown in Figure 14.

[0048] Referring to Figure 15, the graphic 76 is placed on a fabric 80 using the transfer film 79, so that the adhesive layer (hot melt adhesive layer) 30 of the graphic 76 contacts the fabric 80, and the graphic 76 is heat-pressed, for example, at a temperature of 145°C for 30 seconds, in the same way as in Figure 7. After the heat pressing is completed, the transfer film 79 is removed. The graphic 76 (including the pattern 74) is adhered to the fabric 80 by the adhesive formed by the adhesive layer 30. Figure 16 shows the work of heat-pressing the graphic 76 onto a fabric 80. The heat-sublimated pattern 74 is covered with glitter powder 52, becoming a glitter pattern 74 with a shimmering effect.

[0049] Figures 17 and 18 show two heat-pressed patterns 76A and 76B on fabric 80. These two patterns also present two other heat-sublimation patterns 74A and 74B, which are densely covered with glitter powder 52 and have a shimmering effect.

[0050] The glitter film material 10 provided by this invention solves the deficiencies of the prior art. Regarding the glitter powders 52 and 52A, the aluminum inner layer 55 and the zinc sulfide inner layer 56 are encapsulated within the glitter powder. The surface 57 of each glitter powder 52 and 52A is made of polyester material, without any other material. Similarly, the surface 57 of glitter powder 52B is also made of polyester material, without any other components. Therefore, when the sublimation ink of pattern 74 sublimates to the glitter layer 50, the sublimation ink bonds to the polyester surface 57 of the glitter powder, and does not bond to the aluminum or zinc sulfide surface. Thus, the color of the sublimation ink is saturated and vivid, and the pattern 74 has bright, vivid colors and a glossy finish. Furthermore, due to the distinct colors of the ink, it is suitable for printing patterns 74 in multiple colors from the sublimation ink. Patterns 76, 76A, and 76B in Figures 16, 17, and 18 all have multiple colors, and the colors are vivid, with fine lines. Even though the sublimation ink is bonded to the cut surface 58 of the glitter powder 52 and 52A, most of the area of ​​the cut surface 58 is still polyester, and aluminum or zinc sulfide only occupies a small area. Therefore, the sublimation ink still has saturated and vivid colors.

[0051] The glitter film material 10 of this invention allows consumers and businesses to easily create various sublimation patterns 74 on the glitter film material and adhere the glitter sublimation patterns to the fabric, as shown in Figures 5 to 16. The peel force between the adhesive layer 30 and the base layer 20 is between 20 grams and 80 grams per square centimeter, making it easy to separate. In the heat transfer process shown in Figure 7, when the sublimation ink of the sublimation paper 72 is sublimated onto the glitter layer 50 of the glitter film material 10, the hot melt adhesive layer 30 becomes sticky when heated. Because the peel force between the hot melt adhesive layer 30 and the base layer 20 is low, the hot melt adhesive layer 30 is easily separated from the base layer 20. Therefore, when removing waste material W as shown in Figure 12, the user can easily tear off and remove the waste material W, and easily remove fine waste material in the pattern, such as the small triangular waste material in the letter A. The design of the hot melt adhesive layer 30, which is easily separable from the base layer 20, facilitates the removal of fine and complex waste materials. Because the base layer 20 is easily separable from the hot melt adhesive layer 30, the base layer 20 can be easily and smoothly peeled off without damaging the thermal sublimation pattern and the glitter film material.

[0052] In this invention, because the layered heat-resistant component 40 is disposed under the glitter layer 50, it can prevent the adhesive of the adhesive layer 30 from spreading to the glitter layer. Therefore, during the heat sublimation process of the pattern in Figure 7, the sublimation paper 72 will not stick to the adhesive layer 30. In Figure 15, when the pattern 76 is heat-bonded to the fabric 80, the high-temperature barrier layer 42 and / or the adhesive layer 44 can block the adhesive of the adhesive layer 30, preventing the adhesive from spreading to the glitter layer 50 and the ink of the pattern 74, making it easy for the glitter film to separate from the sublimation paper 72.

[0053] When the glitter layer 50 of the glitter film 10 uses the glitter powder 52 shown in Figure 2A, the dye-sublimation pattern 76 can have various colors of glitter luster depending on the color of the inner layer 55. When the glitter layer 50 of the glitter film 10 uses the transparent rainbow glitter powder 52A shown in Figure 2B, the refracted light of the glitter powder 52A is rainbow light, giving the dye-sublimation pattern 76 a rainbow (multicolored) light effect. When the glitter layer 50 of the glitter film 10 uses the transparent glitter powder 52B shown in Figure 2C, the glitter powder 52B still has a glitter effect, and the glitter layer 50 can be formed by mixing a small amount of silver glitter powder with the transparent glitter powder 52B, with the silver light assisting the glitter effect.

[0054] The glitter film material 10 of this invention allows individuals or businesses to create their own preferred heat-sublimation patterns 76. For manufacturers of glitter film materials, this invention reduces the amount of material required for heat-stamping glitter graphics. Manufacturers only need to produce a small number of styles of the glitter film material 10 of this invention, such as silver / transparent / rainbow glitter powder glitter film materials, without the need to produce conventional glitter lettering films 90, 100. Therefore, it can greatly reduce the number of styles to be produced, and also reduce the display space and storage space for goods sold in stores, reduce manufacturing and inventory costs, and meet environmental protection requirements.

[0055] The above-described embodiments are merely illustrative of the features of the present invention and not intended to limit it. Any equivalent modifications that fall within the scope of the claims of this invention should be considered within the protection scope of this invention. This invention represents a first-of-its-kind structure for similar articles and enhances their functionality, thus meeting the requirements for a patent.
