Description

Technical Field

[0001] This utility model relates to the field of cigarette filtration technology, specifically a novel PLA aroma-enhancing membrane and filter paper tube. Background Technology

[0002] Cigarette filter tubes are tools specifically designed for smokers to reduce the amount of smoke, tar, and particulate matter produced during combustion that enters the mouth. The three main functions of cigarette filters include direct interception, inertial compression, and diffusion sedimentation. With technological advancements, increasingly flavored filter tubes are available, enhancing flavor and improving vaping satisfaction.

[0003] Currently, heated tobacco products on the market offer a variety of flavors, which are enhanced by inserting flavoring sheets into the mesh base rod as a way to add aroma to various flavors such as iced blueberry, mint, and orange. However, this method of inserting flavoring sheets increases the complexity of the rod manufacturing process, resulting in higher overall production costs for the filter paper tube. Therefore, a new type of PLA flavoring membrane and filter paper tube is proposed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a novel PLA fragrance membrane and filter paper tube.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel PLA fragrance film includes a PLA film body, the surface of which is formed by pressing to create multiple orderly arranged ridges or grooves, and the surface of the PLA film body is coated with a gel fragrance layer.

[0007] Preferably, the thickness of the gel fragrance layer is 0.01mm-1mm.

[0008] Preferably, the gel fragrance layer is located on one of the surfaces of the PLA membrane.

[0009] A novel filter material paper tube includes a filter material paper tube body, which is a cylindrical structure formed by rolling the aforementioned PLA fragrance film.

[0010] Preferably, the extension direction of the central axis of the filter material paper tube body is consistent with the extension direction of the ridge or groove.

[0011] Preferably, the outer surface of the filter material paper tube body is provided with forming paper.

[0012] Preferably, the gel fragrance layer of the PLA fragrance film is located on the side that does not contact the forming paper.

[0013] This utility model provides a novel PLA fragrance-enhancing membrane and filter paper tube. It has the following beneficial effects:

[0014] In this invention, PLA material has low adsorption and good cooling properties. After the PLA membrane is coated with a gel fragrance, the heat of the smoke during inhalation causes the gel to liquefy and release the fragrance. At the same time, the PLA material is kept from solidifying due to heat contraction. This improves the permeability of smoke and the full release of fragrance during inhalation with the filter paper tube, greatly enhancing the satisfaction of inhalation. In addition, the manufacturing method is simple, which greatly reduces the production cost and makes the fragrance more lasting. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Detailed Implementation

[0020] Example 1:

[0021] like Figures 1-2 As shown, this utility model embodiment provides a novel PLA fragrance film, including a PLA film body 10. The surface of the PLA film body 10 is formed by pressing to create multiple orderly arranged ridges or grooves, which can be formed by compression. A gel fragrance can be coated on the side with the orderly arranged ridges or grooves, thereby forming a gel fragrance layer 11. The ridges or grooves allow the gel fragrance layer 11 to increase the coating area and better adhere to the gel fragrance during coating. The gel fragrance is made by mixing gel and fragrance. The gel can encapsulate the fragrance. The fragrance can be selected from a wide range of options, with minimal impact from water solubility, fat solubility, and flowability. It can be fragrance-carrying activated charcoal or fragrance-carrying granules, and its flavor can be iced blueberry, mint, or orange, etc. The thickness of the gel fragrance layer 11 is 0.01mm-1mm, and the gel fragrance layer 11 is located on one of the surfaces of the PLA film body 10.

[0022] Example 2:

[0023] like Figure 3 As shown, the filter paper tube body 1 is a cylindrical structure made of PLA flavored film. During inhalation, the heat of the smoke liquefies the gel, releasing the aroma, while simultaneously preventing the PLA material from solidifying due to heat contraction. This improves the smoke's permeability and the full release of aroma during filter-assisted inhalation, greatly enhancing the vaping experience. The central axis of the filter paper tube body extends in the same direction as the ridges or grooves to ensure smooth smoke flow. A forming paper 2 is provided on the outer surface of the filter paper tube body 1. The gel fragrance layer 11 of the PLA flavored film is located on the side that does not contact the forming paper 2.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
