Transparent microcapsule filter stick

Abstract

A transparent microcapsule filter stick relates to the technical field of cigarettes and comprises a filter element (1) and a wrapping layer (2), the filter element (1) comprises solid sections (3) and hollow sections (4) which are arranged at intervals, the hollow sections (4) are filled with a plurality of microcapsules (5), and after the filter element is cut into filter stick sections used for manufacturing cigarette filters, each filter stick section comprises one hollow section (4) and two solid sections (3). A large number of micro capsules are added in the transparent cavity, and a consumer can select the number of capsules needing to be pinched to be broken according to the taste requirement of the consumer, so that the amount of fragrance needing to be released can be easily controlled.

Description

Technical Field

[0001] This utility model relates to the field of cigarette technology, specifically to a transparent filter rod with added microcapsules. Background Technology

[0002] The filter stick is an important component of cigarettes. With the continuous development of cigarettes, smokers are increasingly demanding not only higher flavor levels but also improved appearance and appeal. This has led to the emergence of transparent capsule filter sticks with visible internal components. However, existing transparent capsule filter sticks have a problem: when the capsule is broken, all the flavoring inside is released. Consumers who prefer a milder flavor cannot choose the amount of flavor released according to their taste preferences. Furthermore, in existing transparent capsule filter sticks, the capsule is located in a hollow cavity. When the capsule is broken, the cavity loses its internal support, causing it to become flat and difficult to spring back up. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a transparent microcapsule filter rod, which can control the amount of fragrance released by crushing the number of microcapsules.

[0004] The technical solution of this utility model is: a transparent microcapsule filter rod, including a filter element and a coating layer. The filter element includes solid segments and hollow segments arranged at intervals. The hollow segments are filled with a number of microcapsules. After being cut into filter rod segments for manufacturing cigarette filters, each filter rod segment contains one hollow segment and two solid segments.

[0005] The technical advantages of this invention are as follows: A large number of microcapsules are added to the transparent cavity, allowing consumers to choose the number of capsules to break according to their taste preferences, thus easily controlling the amount of aroma released. Due to the large number of microcapsules, even if all are broken, the remaining capsule shells inside the cavity effectively support the outer packaging layer, making the packaging in the cavity easily spring back by the capsule shells and the filter fibers on both sides, preventing the cavity from collapsing and severely affecting its appearance. During smoking, the small capsule size allows consumers to repeatedly squeeze and break the cigarette filter, increasing the enjoyment of smoking. Furthermore, the addition of functional flavorings inside the capsules can enhance the aroma and moisture retention of the filter through repeated applications. Attached Figure Description

[0006] Figure 1 This is a cross-sectional structural diagram of the present invention. Detailed Implementation

[0007] like Figure 1As shown, a transparent microcapsule filter rod includes a filter element 1 and a coating layer 2. The filter element 1 includes solid segments 3 and hollow segments 4 arranged at intervals. The hollow segments 4 are filled with a number of microcapsules 5. After being cut into filter rod segments for manufacturing cigarette filters, each filter rod segment contains one hollow segment 4 and two solid segments 3. The solid segments are located at both ends of the hollow segments and serve a sealing function.

[0008] The filter element 1 is made of cellulose diacetate filaments. The cellulose diacetate filaments on both sides can provide support, and when squeezed, the cavity can quickly spring up under the action of the cellulose diacetate filaments and microcapsules (shells).

[0009] The wrapping layer 2 is made of a transparent material. The filter element can be clearly seen through the transparent wrapping layer, making the cigarette design more diverse.

[0010] The microcapsules 5 have a particle size of less than 1 mm.

[0011] The hollow segment 4 contains more than 100 microcapsules 5. A certain amount of practical pigment can be added to the microcapsule wall to adjust its color. The microcapsule core liquid can be selected from fruit flavorings, humectants, tobacco flavorings, etc., to adjust the smoke and make it more harmonious.
