This utility model provides a sample-keeping anti-counterfeiting incense packaging tube, belonging to the field of incense packaging technology. It includes a top cover, a connecting tube, and an incense tube. The connecting tube has a reserved channel with a limiting component. The limiting component contains multiple radially distributed tooth-shaped elastic limiting pieces. In its natural state, the tips of the elastic limiting pieces form a conical protrusion, enclosing a closed limiting hole. This utility model, through the deformation and reset characteristics of the elastic limiting pieces, strictly restricts the incense to only moving from the incense tube towards the top cover for sample incense sampling and inspection. Once all incense is removed, it cannot be reversed, preventing incense inconsistent with the incense already in the tube from being mixed back into the tube. This avoids confusion between different batches and qualities of incense, ensuring the consistency between the incense quality in the packaging tube and the seller's quality commitment. This helps quality-conscious and reputable companies protect their products from counterfeiting or malicious complaints and claims.
