AI Technical Summary

Benefits of technology

The patent is about improving the quality of oral pouched snuff products by using ultrasonic welding instead of heat-melt welding to create seals. Ultrasonic welding allows for the creation of seals that are tidier, more visually appealing, and more discrete. Additionally, the amount of pouch material required is reduced. The strength of the seal is also better preserved upon storage of the product. Overall, this process improves the quality and experience of oral pouched snuff products.

Problems solved by technology

The initial amount of flavours and / or nicotine released from the pouched tobacco may be experienced by the consumer as unsatisfactory or even negligible.
This problem is often more pronounced for non-post-moisturized oral pouched snuff products.
However, production methods wherein polymeric fibres have to be melt-blown in situ are rather complicated, time-consuming and expensive and require further apparatus in addition to the conventional packaging devices described herein above.

nt of Seal Strength Resulting from Heat-Melt Welding and Ultrasonic Welding

[0213]The elastic mesh material as well as the nonwoven reference material was heat-melt welded and ultrasonically welded and the seal strength of the resulting samples was measured.

Heat-Melt Welding

[0214]A strip of the nonwoven reference material having a length of about 1 m in the machine direction, MD, of the material and a width of 4 cm in the cross direction, CD, of the material was cut out. The strip was double-folded to obtain a two-layered material, which was about 4 cm×50 cm.

[0215]The two layers of the double-folded strip were welded to each other along the CD direction as well as along the MD direction of the material in a HS-2 laboratory heat sealer from RDM equipment. The dimensions of upper and lower seal bars were 50 mm×5 mm. The seal bars were applied such that the 50 mm direction was perpendicular to the length direction of the double-folded strip.

[0216]The upper seal bar was heated to about 3...

o Withstand Aggressive Flavors Known to Affect Seal Strength

[0248]Samples of the ultrasonically welded and the heat melt welded elastic mesh material and the nonwoven reference material prepared as described in Example 1, were placed in a first compartment of a two-compartment container. A flavor (in oil form) known to impair seal strength was placed in the other compartment. The flavor is also known to dissolve the binder present in nonwoven material normally used and thereby impair the tensile strength thereof.

[0249]The container was thereafter closed and the samples were stored in the container for two days (about 48 hours). Thereafter, the seal strength of each sample was measured.

[0250]The results (average values of 10 measurements for seal strength and average values of 5 measurements for tensile strength) are presented in Table 1. Standard deviation is included in Table 2 for the seal strength measurements.

ion of Seal Strength Upon Storage of Oral Pouched Snuff Product

[0252]A tobacco composition (snus composition), having moisture content of about 50-60% w / w, such as 56% w / w, based on the total weight of the composition, is portion-packed in pouches of the elastic mesh material of Example 1 using the herein disclosed arrangement utilizing ultrasonic welding for sealing the pouches.

[0253]The same tobacco composition is also portion-packed in pouches of the nonwoven reference material of Example 1 using conventional portion-packing apparatus utilizing heat melt welding for sealing the pouches.

[0254]The seal strength of some of the resulting oral pouched snus products is measured. Some of the resulting pouched snus products are stored in a refrigerator for about 3 weeks. Thereafter, the seal strength of the stored products is measured.

Abstract

The present disclosure relates to an oral pouched snuff product and a method for its production. The oral pouched snuff product comprises a filling material and a saliva-permeable pouch enclosing the filling material, the saliva-permeable pouch comprising at least one elongated seal and the saliva-permeable pouch comprising a mesh material being elastic in at least one direction and comprising fibres of thermoplastic polyamide, wherein the at least one elongated seal has a seal strength of at least 0.10 N / mm as measured in dry state as well as in wet state. The at least one elongated seal may be an ultrasonically provided weld.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims priority to European Patent Application No. 16201939.2 filed on Dec. 2, 2016, and European Patent Application No. 16203426.8, filed on Dec. 12, 2016, the disclosures of which is hereby expressly incorporated by reference in their entireties.TECHNICAL FIELD[0002]The present invention relates to an oral pouched snuff product, such as an oral pouched smokeless tobacco product, comprising a filling material, such as tobacco material, and a saliva-permeable pouch enclosing the filling material.BACKGROUND[0003]Smokeless tobacco for oral use includes chewing tobacco, dry snuff and moist (wet) snuff. Generally, dry snuff has a moisture content of less than 10 wt % and moist snuff has a moisture content of above 40 wt %. Semi-dry products having between 10% to 40 wt % moisture content are also available.[0004]Smokeless tobacco products for oral use are made from tobacco leaves, such as lamina and stem of the tobacco leaf.
