Definitions

• the present invention relates to a flavor generating product.
• Flavor inhalers for inhaling flavors and the like without burning any material are known. Flavor inhalers have, for example, a chamber that contains a flavor-generating product and a heater that heats the flavor-generating product contained in the chamber (see, for example, Patent Document 1).
• Aerosol base materials, flavorings, or other additives may be added to the flavor generating section of a flavor generating article used in a flavor inhaler such as that disclosed in Patent Document 1. Such additives may soak into the wrapping paper and crystallize on the surface of the wrapping paper. Such crystallization may mar the appearance of the flavor generating article and may also stain the user's hands. Note that aerosol generating articles equipped with first and second trumpets to prevent leakage of liquid components from the wrapping paper are also known (see Patent Document 2).
• the second trumpet and the first trumpet are bonded with an adhesive such as glue, there is a risk of wrinkles occurring on the second trumpet.
• the first adhesive portion is provided in the above-mentioned region, the first trumpet and the second trumpet are not bonded over the entire circumference, so that it is possible to prevent wrinkles from occurring on the second trumpet.
• the amount of adhesive used to bond the first trumpet and the second trumpet can be reduced, it is also possible to prevent increases in manufacturing costs and the occurrence of device contamination caused by the adhesive. It is more preferable that the first adhesive portion is provided in an area of 35% or less of the entire circumference of the second trumpet, and even more preferable that it is provided in the above-mentioned region of 25% or less.
• the adhesive area between the upstream portion and the second trumpet is larger than the adhesive area between the first rod portion and the second trumpet, so the second trumpet can be firmly attached to the upstream portion while suppressing the occurrence of wrinkles at the adhesive portion between the second trumpet and the first rod portion.
• the first portion in which a relatively small amount of adhesive is applied, can prevent the flavor-generating item (upstream portion) from igniting due to the presence of adhesive when a user accidentally brings a fire close to the flavor-generating item.
• the second portion in which a relatively large amount of adhesive is applied, can firmly bond the second trumpet to the upstream portion. Furthermore, the occurrence of wrinkles in the second trumpet at the second adhesive portion can be prevented compared to when a relatively large amount of adhesive is applied throughout the second adhesive portion.
• the second trumpet and the upstream portion can be firmly attached by the second portion along the circumferential direction, which further prevents the upstream portion from falling off the second trumpet.
• the second portion may extend over an area that is 50% or more of the entire circumference of the upstream portion.
• the second trumpet may have both circumferential ends, and the second portion may be positioned away from the both circumferential ends.
• the longitudinal length of the upstream portion may be 5 mm or more and 10 mm or less.
• the upstream portion has a length of less than 1 mm, it may not be able to maintain its shape during cutting, and may be deformed, for example, crushed. If the length of the upstream portion in the longitudinal direction is 1 mm or more, it may be manufactured relatively easily. In particular, if the length of the upstream portion in the longitudinal direction is 5 mm or more, it may be manufactured even more easily. Furthermore, if the upstream portion is more than 10 mm, there is a risk that the airflow resistance of the flavor-generating article may become too high. Therefore, by setting the length of the upstream portion within the above range, it is possible to easily manufacture the upstream portion while preventing the airflow resistance of the flavor-generating article from becoming too high. Furthermore, if the length of the upstream portion in the longitudinal direction is 5 mm or more, a sufficient adhesive area between the second trumpet and the upstream portion may be secured, and therefore it is possible to further prevent the upstream portion from falling off the second trumpet.
• the flavor generating article may include a second rod portion disposed downstream of the first rod portion, and the second trumpet may surround at least a portion of the second rod portion.
• the second trumpet and the second rod portion are firmly attached to each other, preventing the second rod portion from falling off the second trumpet.
• the area of the third adhesive portion per unit length in the longitudinal direction may be greater than the area of the first adhesive portion per unit length in the longitudinal direction.
• the adhesive area between the second rod portion and the second trumpet is larger than the adhesive area between the first rod portion and the second trumpet, so the second trumpet and the second rod portion can be firmly attached while suppressing the occurrence of wrinkles at the adhesive portion between the second trumpet and the first rod portion.
• the third adhesive portion may have a third portion and a fourth portion having a larger amount of adhesive applied thereto than the third portion.
• the third portion where a relatively small amount of adhesive is applied, can prevent the flavor-generating item (second rod portion) from igniting due to the presence of adhesive when a user accidentally brings a fire close to the flavor-generating item.
• the fourth portion where a relatively large amount of adhesive is applied, can firmly bond the second trumpet and the second rod portion. Furthermore, the occurrence of wrinkles in the second trumpet at the third adhesive portion can be prevented compared to when a relatively large amount of adhesive is applied throughout the entire third adhesive portion.
• the fourth portion may extend circumferentially around the second rod portion.

• the opening is formed by laser after assembly of the flavor generating article, the opening is formed in the exposed portion where the wrapping paper does not overlap, so the laser output can be reduced.
• the third adhesive portion is not provided in the exposed portion, when the opening is formed by laser after assembly of the flavor generating article, the generation of dust containing adhesive can be suppressed, and the frequency of cleaning the device for forming the opening can be reduced.
