Description

Method for manufacturing outer container with water-insoluble film-sealing capsule

The invention relates to a method for manufacturing an outer container having a water-insoluble film-sealing capsule, in particular to a non-water-soluble film-sealing capsule which is easily broken between an open end and a film, and an outer container containing the capsule method.

In the conventional filter cigarette, the filter may be composed of a cellulose acetate tow filter plug wrapped around a porous filter plug wrap. Filter cigarette with a multi-component filter that includes two or more stages of filter material for removing particulates and gas components of mainstream smoke.

Many smoking articles in which aerosol-forming substrates such as tobacco are heated rather than burned are also proposed in the technology. In heated smoking articles, the aerosol is produced by heating the aerosol to form a substrate, wherein the aerosol is generated by electrical heating or by transferring the heat of a flammable fuel element or heat source to the aerosol to form the substrate . During smoking, volatile compounds are released from the aerosol-forming substrate and entrained in the air inhaled by the smoking article. The aerosol-forming substrate is heated by heat transfer from a heat source. The released compounds will condense when they cool and form an aerosol that consumers can inhale. Such smoking articles have also been known, in which the production of nicotine-containing aerosols can come from tobacco materials, tobacco extracts, or other sources of nicotine, which do not require combustion and in some cases do not require heating, but for example via chemical reaction.

It is known to incorporate flavor additives into smoking articles to provide additional odor during smoking by consumers. Flavors can be used to enhance the production of tobacco materials when heating or burning tobacco materials Tobacco odor, or used to provide additional non-tobacco odor, such as peppermint or menthol (Menthol). Flavor additives used in smoking articles, such as menthol, usually take the form of a content fragrance, which is incorporated into the filter or tobacco rod of the smoking article using a suitable content carrier. The content fragrance is usually volatile, so it will be transferred or evaporated from smoking products during storage. Therefore, the amount of spices used for mainstream smoke odors during smoking is reduced.

It has previously been proposed to encapsulate fragrances, for example in the form of capsules or microcapsules, to reduce the loss of volatile fragrances from smoking articles. The packaged fragrance can be released by breaking the package structure (for example, by crushing or melting the structure) before or during smoking of the smoking article. In the case of breaking these capsules to release the fragrance, the capsule will break open under a certain force and release the fragrance.

In this way, Chinese Patent Publication No. CN104780793A has disclosed a capsule that encloses the content, which is mainly squeezed from both sides in the diametrical direction of the capsule by external force to cause internal pressure to form inside the capsule. Wall area), so when the internal pressure of the capsule is applied to the end wall, it will break from the center of the bottom of the specific V-shaped groove, so that the contents of the capsule are ejected from the broken position of the V-shaped groove toward the center of the filter element .

However, when the capsule is squeezed and internal pressure is formed inside, the user must apply a certain force to make the internal pressure sufficient to break its thin-walled area, so as to lead out the contents of the capsule.

The following describes specific embodiments to illustrate the implementation of the present invention, but it is not intended to limit the scope of the invention to be protected.

Please refer to FIGS. 1 and 2, which are a flowchart of steps and a schematic diagram of a water-insoluble capsule sealing film according to the first embodiment of the present invention, as shown in the figure. The present invention provides a method for manufacturing an outer container having a water-insoluble film-sealing capsule, which is applied to a drug delivery device or a cigarette filter. The procedure includes filling a content 13 in a water-insoluble capsule 10 (S01), an accommodating space 11 is recessed inside the water-insoluble capsule 10 for the content 13 to be filled, and because the water-insoluble capsule 10 is not water-soluble, the content 13 may be oily, water-based or paste The shape of the shape and so on.

Then, a film 20 is used to cover an open end 12 provided at one end of the water-insoluble capsule 10, and the content 13 is filled into the accommodating space 11 from the open end 12, so when the content 13 is filled After the completion, the sealing film 20 can be used to cover the open end 12 to close the accommodating space 11 (S02); afterwards, the sealing film 20 can be connected to the outer edge of the open end 12 through a film procedure Combined with (S03), the film sealing process can be heat sealing film or ultrasonic film sealing. For example, when an ultrasonic device is activated, the ultrasonic device generates a high frequency of about 15KHz to 20KHz from a sound generator Signal to directly contact the sealing film 20 on the outer edge of the open end 12 through the welding head of the energy converter (HORN) fixed on the ultrasonic device, so as to make the molecules in the sealing film 20 by high-frequency vibration Strong friction occurs and local high temperature is generated. When the temperature is higher than the melting point of the sealing film 20, the sealing film 20 on the outer edge of the open end 12 will melt, and after the molten sealing film 20 cools , The sealing film 20 will be re-cured and adhered to the outer edge of the open end 12, so that the effective The sealing film 20 is combined with the outer edge of the open end 12. Thus, when the sealing film 20 is combined with the outer edge of the open end 12, the content 13 is completely sealed in the water-insoluble capsule 10.

Finally, the water-insoluble capsule 10 is placed in an outer container (S04), one end of the outer container is opened for the water-insoluble capsule 10 to be placed, and then placed or fixed in the outer container through at least one absorber One end or both ends to close the water-insoluble capsule 10 in the outer container (S05); however, the water-insoluble capsule 10 is made of an elastic polymer material, and the outer container is made of an elastic material, so The user can apply pressure on either side of the outer container to squeeze the water-insoluble capsule 10, so that an internal pressure is generated inside the water-insoluble capsule 10, and then the sealing film 20 can not bear the internal pressure and interact with the The open end 12 is phase separated, by which the content 13 can be effectively derived. Wherein, the outer container is specifically the outer packaging material of the drug delivery device or the outer packaging material of the cigarette filter, and the absorber is specifically a filter material provided in the drug delivery device or the cigarette filter.

Furthermore, when the sealing process is performed, the welding head of the energy converter (HORN) is used as an example to directly contact the sealing film 20 located on the outer edge of the open end 12, so when When high temperature is generated due to high-frequency vibration, the high temperature directly weakens the structural strength of the outer edge of the open end 12. In addition, because the thickness of the sealing film 20 is between 0.01 mm and 0.3 mm, more preferably between 0.05 mm and 0.2 mm, and the thickness of the water-insoluble capsule 10 is between 0.05 mm and 2 mm, more preferably The ground is between 0.1 mm and 1 mm, so the structural strength of the water-insoluble capsule 10 is greater than that of the open end 12 and the sealing film 20. In this way, when the user squeezes the outer container to cause the internal pressure inside the water-insoluble capsule 10, the sealing film 20 is combined with the outer edge of the open end 12, the sealing film 20 or the open end The structural strength of 12 is obviously smaller than that of the water-insoluble capsule 10, so the internal pressure will be ruptured from the junction of the sealing film 20 and the outer edge of the open end 12, the sealing film 20 or the position of the open end 12 Instead of bursting from any position on the water-insoluble capsule 10.

Please refer to FIG. 3 and FIG. 4, which is a flowchart of the steps of the second embodiment of the present invention and a schematic diagram of the water-insoluble capsule sealing film, as shown in the figure. The difference between the second embodiment and the first embodiment is that when the second embodiment is filled with a content 13 in a water-insoluble capsule 10, a gas space 30 is reserved in the water-insoluble capsule 10 to store a Gas is filled into the gas space 30 (S06), so that the gas in the gas space 30 reaches a certain saturation state, the gas system may be oxygen, nitrogen or air; thus, when the water-insoluble capsule 10 passes through When the sealing film 20 closes the open end 12, a gas and a content 13 are contained in the water-insoluble capsule 10. When the user squeezes the outer container to squeeze the water-insoluble capsule 10, the gas in the water-insoluble capsule 10 is also compressed due to the instantaneous change in the volume of the water-insoluble capsule 10. The structural strength of the membrane 20 and the open end 12 is less than that of the water-insoluble capsule 10, so when the gas is compressed, it will burst out from the position of the sealing membrane 20 and the open end 12, however, when the gas is flushed out , The impulse will eject the content 13 from the position of the sealing film 20 and the open end 12 in order to effectively lead out the content 13 and absorb the content by at least one absorber.

The above detailed description is a specific description of a feasible embodiment of the present invention, but this embodiment is not intended to limit the patent scope of the present invention, and any equivalent implementation or change without departing from the technical spirit of the present invention should be included in The patent scope of this case.
