摘要： Nonwoven web comprising thermoplastic meltblown fibers or filaments predominantly present as agglomerates or multiple fused fiber areas. Such agglomerates in the web act as columns and impart a desired degree of strength and resistance to compaction. In contrast to prior art webs where such agglomerates have been considered undesirable, the webs of the present invention find particular utility when formed into cylinders as filter plugs for smoking articles. In smoking articles of the invention, the filter plugs have a desired pressure drop while demonstrating an unexpected degree of firmness, all at an economically attractive cost. Preferred embodiments include those where the machine direction strength to cross machine direction grab tensile ratios in the range of from about 1:1 to 4:1 and the fibers or filaments are made from polypropylene. Other embodiments include webs and filter plugs containing additives distributed throughout the web.

摘要： A wrapper particularly useful for smoking articles of the type containing a burn fuel element and ceramic jacket. The wrapper includes an inner layer for surrounding the burn fuel element and jacket and an outer layer with the combination imparting controlled throttling properties. The inner layer may be a conventional cigarette wrapper material of cellulosic construction and having biased burned properties. The outer layer surrounds the inner sheet and preferably comprises cellulose fibers, titanium dioxide, attapulgite clay, high temperature resistant microfibers, and a burn enhancer. The outer wrapper also maintains permeability and pressure drop properties at temperatures in excess of 400.degree. C. while the inner wrapper burns out resulting in generally infinite permeability after burning. The combination in use possesses sufficient mechanical strength to support the assembly of components in specialty smoking articles and as burned properties that produce an ash appearance similar to conventional cigarette ash and has a high degree of ash integrity.

摘要： The present invention relates to an improved wrapper for a smoking article haviing a combustible fuel element encircled by an insulating layer and a physically separate aerosol generating means as well as to smoking articles employing such wrappers. The wrapper encircles at least a portion of the insulating layer for the fuel element and comprises a permeable sheet material which during burning of the fuel provides a coherent layer to assist in controlling the amount of peripheral air to the fuel element during smoking.Preferred smoking articles which employ the wrapper of the present invention have a short fuel element, a physically separate aerosol generating means including an aerosol forming material, an insulating material around the fuel element, a relatively long mouthend piece, and a combination of sheet materials as the wrapper comprising an innerwrap which after lighting of the fuel element burns away to a high permeability non-coherent ash and an outerwrap which upon lighting fuses to form a coherent ash which assists in controlling the amount of peripheral air to the fuel element during smoking.

摘要： There is disclosed a package with controlled humidity for storing products such as tobacco and food. Teh package is an enclosed container with a humidistat pad inside which pad serves as a spacer and holds a humectant solution in its liquid phase in an absorbent interior layer. The pad has a liquid impervious backing layer to protect the walls of the container from the liquid humectant solution. The pad also has a liquid permeable cover which can rapidly transfer the humectant solution deposited on it to the absorbent layer during filling of the container with the product.

摘要： The invention is an improved specially designed wrapper construction for smoking articles producing controlled burn properties of smoking articles such as cigarettes so that the cigarette will self-extinguish after free burning in air for a designed time period. In addition, the wrapper construction results in cigarettes with reduced tendency to ignite combustible substrates, such as upholstered furniture, when in contact with them. Therefore, smoking articles with this wrapper construction reduce the likelihood of accidental fires, yet they free-burn rapidly for a designed period of time without puffing. However, during a normal puffing sequence the behavior of cigarettes with these wrappers is indistinguishable from commercial cigarettes. On the other hand, other self-extinguishing cigarettes go out without puffing and therefore have to be relighted frequently. The wrapper constructions of the present invention include single or double wraps of cigarette paper which are inherently incapable without elevated levels of burn promoting chemical or supporting cigarette free burn. The construction is modified by application of a plurality of zones of elevated levels of burn promoter to the extent that the cigarette burns normally in the treated zones. Thus, when the burning coal advances to an area of untreated wrap, it reliably self-extinguishes unless puffed. The extent of the treated zones controls the time required for the cigarette to self-extinguish. Required wrappers are preferably those having a Burn Mode Index ("BMI") as defined in the range of from about 1.5 cm.sup.-1 to about 6.0 cm.sup.-1 for the single wrap embodiment and, for the double wrap embodiment, about 0.1 cm.sup.-1 to about 4.0 cm.sup.-1 for the inner wrap and about 2 cm.sup.-1 to about 40 cm.sup.-1 for the outer wrap depending on the BMI of the inner wrap. The wrappers and smoking articles of the invention may be produced using conventional methods and equipment.
摘要翻译： 本发明是一种改进的专门设计的吸烟制品的包装结构，其产生诸如香烟之类的吸烟制品的受控烧伤性质，使得香烟在空气中在设计的时间段内自由燃烧后自熄。 此外，包装结构导致香烟与其接触时具有降低易燃点燃易燃基材（例如软体家具）的倾向。 因此，使用这种包装结构的吸烟物品可以减少意外火灾的可能性，但是在设计的时间段内可以快速自由燃烧而不会膨胀。 然而，在正常膨化序列期间，这些包装纸的香烟行为与商业香烟是无法区分的。 另一方面，其他自熄香烟不会膨胀，因此必须经常重燃。 本发明的包装结构包括卷烟纸的单卷或双卷，其固有地不能在没有升高的燃烧程度的情况下促进化学或支持无烟燃烧。 通过施加多个升高级别的燃烧促进剂的区域来修饰该构造，使得卷烟在处理区域中正常燃烧。 因此，当燃煤进入未处理包装的区域时，除非膨胀，否则可靠地自熄。 处理区域的范围控制香烟自熄的时间。 所需的包装物优选为具有如单一包装实施方案的约1.5cm -1至约6.0cm -1范围内所定义的燃烧模式指数（“BMI”）的那些，并且对于双包装实施方案，约为0.1cm- 根据内包裹物的BMI，用于内包装为1至约4.0cm -1，外包装为约2cm -1至约40cm -1。 本发明的包装纸和吸烟制品可以使用常规方法和设备制造。

摘要： The invention is an improved wrapper construction for smoking articles such as cigarettes resulting in a reduced tendency to ignite combustible materials accidentally or carelessly coming into contact with the lit cigarette. The wrapper constructions and smoking articles of the invention have a specially designed structure which causes a cigarette to go out quickly when in contact with a substrate, including many commonly-encountered substrates made of combustible materials. This structure is characterized by a Burn Mode Index ("BMI") as defined for the wrapper of between about 1.5 cm.sup.-1 and 5.0 cm.sup.-1 for a single wrap embodiment. For an alternative double wrapped embodiment, the outer wrap will have a BMI in the range of from about 2.0 cm.sup.-1 to about 40 cm.sup.-1 depending on the BMI of the inner wrap which may vary between about 0.1 cm.sup.-1 to 4.0 cm.sup.-1. The preferred amount of burn promoter is at least 15 mg anhydrous potassium citrate per gram of bone dry paper or stoichiometrically equivalent amounts of other burn promoting salts.Preferred substrate embodiments include paper made from flax or other cellulosic fibers, treated with elevated amounts of an alkali metal burn promoter such as alkali metal salts of carboxylic acids, especially potassium salts. In contrast to other attempts, these results are obtained without a significant sacrifice of desired taste and smoke deliveries, for example, without unacceptable increases in puff count or significant increases in delivered tar and carbon monoxide. Wrapper constructions and smoking articles of this invention may be manufactured using conventional cigarette paper processes and equipment.
摘要翻译： 本发明是一种用于吸烟制品（例如香烟）的改进的包装结构，导致意外或不小心与点燃的香烟接触的点燃可燃材料的倾向降低。 本发明的包装结构和吸烟制品具有特别设计的结构，其使香烟在与基材接触时迅速脱出，包括许多常见的由可燃材料制成的基材。 该结构的特征在于，对于单个包装实施例，对于包装物定义的燃烧模式指数（“BMI”）为约1.5cm -1至5.0cm -1。 对于替代的双重包装实施方案，外包装的BMI将在约2.0cm -1至约40cm -1的范围内，这取决于内包装的BMI，其可以在约0.1cm -1至4.0cm之间变化 -1。 燃烧促进剂的优选量为每克骨干纸或化学计量当量的其它燃烧促进盐至少15mg无水柠檬酸钾。 优选的基材实施方案包括由亚麻或其它纤维素纤维制成的纸，用升高量的碱金属燃烧促进剂如羧酸的碱金属盐，特别是钾盐处理。 与其他尝试相反，这些结果是在没有所需味道和烟雾输送的显着牺牲的情况下获得的，例如，没有不可接受的抽吸计数增加或递送的焦油和一氧化碳的显着增加。 可以使用常规卷烟纸工艺和设备来制造本发明的包装结构和吸烟制品。
