Description

Technical Field

[0001] This invention discloses a temperature-indicating sealing heat shrink tubing for cigar filter mouthpieces. Background Technology

[0002] The applicant previously applied for patent 2026203232066, which is a special disposable filter mouthpiece suitable for cigars of different diameters. In this patent, a sealed heat shrink tube is installed at the front end of the mouthpiece shell, which makes it convenient to insert cigars of the corresponding diameter into the sealed heat shrink tube. The sealed heat shrink tube is heated with a lighter and heat shrinks to install at the front end of the mouthpiece shell, preventing the cigar mouthpiece from cracking. It can be used to shrink and install cigars of different diameters using a sealed heat shrink tube.

[0003] However, since the patent only applies for the heat shrink structure of the heat shrink tube, the heating temperature range cannot be known, and the operation often exceeds the temperature. The installation firmness at a reasonable temperature is somewhat lacking. Summary of the Invention

[0004] To address existing problems, this invention provides a temperature-indicating sealing heat shrink tubing for cigar filter mouthpieces, comprising a filter mouthpiece housing with a mouthpiece fixing portion, characterized in that: it includes a sealing heat shrink tubing, which is heated and installed in the mouthpiece fixing portion, and the sealing heat shrink tubing has a temperature-sensitive color-changing area covered with a temperature-sensitive color-changing coating.

[0005] Preferably, the sealing heat shrink tubing can also be fitted onto the mouthpiece fixing part.

[0006] Preferably, the temperature-sensitive color-changing zone is provided along the inner circumference of the sealed heat shrink tubing.

[0007] Preferably, the temperature-sensitive color-changing area is annular or geometric in shape, and the temperature-sensitive color-changing area can also be integrally arranged on the inner circumference of the sealed heat shrink tubing.

[0008] Preferably, the temperature-sensitive color-changing layer is replaced by a temperature-sensitive color-changing adhesive, which is adhered to the surface of the sealed heat shrink tubing.

[0009] Preferably, the thermochromic adhesive includes an adhesive layer and a thermochromic coating, wherein the adhesive layer is adhered to the thermochromic area, and one side of the adhesive layer is covered with the thermochromic coating.

[0010] Preferably, it further includes a hot melt adhesive coating, which covers the temperature-sensitive color-changing area, and the surface of the hot melt adhesive coating is covered with a temperature-sensitive color-changing coating.

[0011] The technical effects of this invention are as follows: Regarding 2026203232066, a sealed heat shrink tube suitable for disposable filter mouthpieces of cigars of different diameters is provided. This invention combines the installation structure with a temperature sensing function. The heat-sensitive color-changing area changes color after heating, ensuring that the heat shrink tube is firmly installed in the mouthpiece fixing part at a reasonable heating temperature. This serves as an overheating warning, making it easy to understand the heating temperature range and thus facilitating better heat shrink installation of the heat shrink tube in the mouthpiece fixing part.

Detailed Implementation

[0018] Example 1 This application is based on the applicant's previous application 2026203232066, which describes a special disposable filter mouthpiece suitable for cigars of different diameters. In that patent, a sealed heat-shrink tube is installed at the front end of the mouthpiece shell, making it convenient to insert cigars of the corresponding diameter into the sealed heat-shrink tube. The sealed heat-shrink tube is heated with a lighter and heat-shrinked to install at the front end of the mouthpiece shell, preventing the cigar mouthpiece from cracking. It can also be used to shrink and install cigars of different diameters using a sealed heat-shrink tube.

[0019] Because the previous patent only applied for the heat shrinkable structure of the heat shrink tube, it could not provide information on the heating temperature range, leading to frequent overheating and insufficient installation firmness at a reasonable temperature. This application describes the design of a structure where the heat shrink tube is installed on one end of the filter mouthpiece shell after heat shrinking, and the installation structure of the heat shrink tube in conjunction with the filter mouthpiece shell after heating. This optimizes the shortcomings of the previous application's sealing heat shrink tube, which could only shrink without knowing the heat shrinking temperature range, frequently leading to overheating and insufficient firmness. It achieves the goal of continuously rotating the sealing heat shrink tube to heat and change color to reach the appropriate temperature for sealing in the mouthpiece fixing part.

[0020] In Example 1, as Figure 1-5 As shown, this embodiment provides a sealing temperature indicating heat shrink tubing for cigar filter mouthpieces, including a filter mouthpiece housing 1, which has a mouthpiece fixing part 11, and a sealing heat shrink tubing 2, which is made of transparent rubber. The sealing heat shrink tubing has a temperature indicating function; primarily, when heated and heat-shrinked by a lighter, the temperature-sensitive color-changing area changes color to indicate the heating temperature of the seal. The sealing heat shrink tubing is heated and installed in the mouthpiece fixing part 11, and the sealing heat shrink tubing has a temperature-sensitive color-changing area 21. The temperature indication function of the sealing heat shrink tubing after being heated by a lighter is achieved through a color-changing mechanism.

[0021] The heat shrink tubing mentioned above is a packaging material that shrinks tightly to wrap products when heated. Its core materials mainly include thermoplastics such as polyethylene (PE), polyvinyl chloride (PVC), polyester (PET), PET-G, POF, and OPS. Different materials have different characteristics and are suitable for different scenarios: PE (polyethylene): good flexibility, tear resistance, puncture resistance, good environmental performance, and widely recyclable. PVC (polyvinyl chloride): high transparency, large shrinkage rate, but may release trace amounts of harmful gases when heated. PET / PET-G: environmentally friendly and recyclable, dimensionally stable, and highly transparent. PET-G has a shrinkage rate of up to 80% and is an internationally recognized mainstream environmentally friendly material. POF (multilayer co-extruded film): high gloss and good toughness. OPS (heat shrinkage film): non-toxic, odorless, and with excellent printability.

[0022] In addition, the heat shrink tubing can also be used to seal the mouthpiece fixing part on the filter mouthpiece housing, which is not described in this application.

[0023] Structures that can be configured as temperature-sensitive color-changing zones include: Figure 1-3 As shown, the temperature-sensitive color-changing area 21 is disposed along the inner circumferential surface of the sealed heat shrink tubing 2. The temperature-sensitive color-changing area 21 is annular in shape (e.g., Figure 2 (as shown) or geometric shapes (such as) Figure 3 As shown in the figure, the circular shape can be flexibly configured in various ways. The annular shape is set along the inner circumference of the sealed heat shrink tubing, while the geometric shape can be set with multiple temperature-sensing points along the inner wall of the sealed heat shrink tubing. The temperature-sensitive color-changing coating 21 can also be set on the entire inner wall of the sealed heat shrink tubing 2 (e.g., ...). Figure 1 (As shown). The placement is flexible.

[0024] like Figure 4-5 As shown, the surface of the temperature-sensitive color-changing area 21 is covered with a temperature-sensitive color-changing coating 31, which directly covers the temperature-sensitive color-changing area.

[0025] The temperature-sensitive color-changing area can also be a multi-layered covering structure, which further includes a hot melt adhesive coating 32. The hot melt adhesive coating covers the temperature-sensitive color-changing area on the inner wall of the sealed heat shrink tubing, and a temperature-sensitive color-changing coating is also covered on the surface of the hot melt adhesive coating.

[0026] As a transformable and flexible structure, such as Figure 6 As shown, the temperature-sensitive color-changing layer is replaced by a temperature-sensitive color-changing adhesive 4. The temperature-sensitive color-changing adhesive 4 includes an adhesive layer 41 and a temperature-sensitive color-changing coating. The adhesive layer is adhered to the temperature-sensitive color-changing area, and one side of the adhesive layer is covered with the temperature-sensitive color-changing coating 31. This facilitates replacement.

[0027] Thermochromic layers are the color-changing layers in thermosensitive coatings, and they are crucial for achieving color changes. Depending on the type, they can be categorized as follows: Organic: Colorless dyes such as crystal violet lactone (CVL) and fluorescein act as electron donors, combined with color developers such as bisphenol A (electron acceptors), achieving reversible color change through proton or electron transfer. Inorganic: Iodides (Ag₂HgI₄, Cu₂HgI₄) or metal salts (cobalt, nickel, iron salts) achieve color change through crystal transformation or decomposition reactions. Liquid crystals: Cholesteric liquid crystal materials reflect different wavelengths of light based on pitch changes with temperature. Paint base / binder: Used to support and fix the color-changing material; common examples include oil-based varnishes and transparent resins (such as melamine resin and acrylic resin), which must possess good film-forming properties and heat resistance.

[0028] The above embodiments illustrate the structure of this application.

[0029] The following application uses a series of experimental data to demonstrate the discoloration of the sealed heat shrink tubing under different temperatures: When the lighter heats the sealing heat shrink tube to 70 degrees Celsius, the temperature-sensitive color-changing area on the sealing heat shrink tube changes from white to black after heating. Similarly, when the temperature-sensitive color-changing area on the sealing heat shrink tube is heated to 80 degrees Celsius, the color also changes from white to black.

[0030] When the temperature of the heat-shrinkable tube heated by the lighter exceeds 70 degrees Celsius, the temperature-sensitive color-changing zone on the heat-shrinkable tube changes color in different ways. For example, the temperature-sensitive color-changing zone is originally red but turns yellow when the temperature exceeds 70 degrees Celsius; the temperature-sensitive color-changing zone is originally blue but turns yellow when the temperature exceeds 70 degrees Celsius; the temperature-sensitive color-changing zone is originally black but turns red when the temperature exceeds 70 degrees Celsius; the temperature-sensitive color-changing zone is originally green but turns yellow when the temperature exceeds 70 degrees Celsius; and the temperature-sensitive color-changing zone is originally orange but turns yellow when the temperature exceeds 70 degrees Celsius.

[0031] During use, the sealing heat shrink tube fitted onto the cigarette holder is rotated while being heated. When a certain heating temperature is reached, the heat shrink tube changes color and shrinks, indicating that the temperature at that location has been reached. The lighter can be used to heat the sealing heat shrink tube in another location to produce the corresponding color change and shrinkage. Rotating the sealing heat shrink tube at any time to change color and heat it serves as an overheat protection function.

[0032] In practical applications, the sealing heat shrink tubing is used by attaching it to the cigarette holder fixing part or by heating. This application mainly applies for heating, while attaching it is another auxiliary installation structure.

[0033] During heating, use a lighter to evenly heat the sealed heat shrink tubing back and forth. Since the sealed heat shrink tubing has a temperature-sensitive color-changing zone, heating the temperature-sensitive color-changing zone to 80 degrees Celsius with a lighter will enable the sealed heat shrink tubing to shrink. Color changes will occur at the different temperatures mentioned above. Please refer to the color-changing instructions for the different temperatures mentioned above so that users can understand the heating temperature range.

[0034] It should be noted that the above preferred embodiments are merely illustrative of the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
