However, when someone asked to consider his or her behavior and sleep required to perform a manual conversion from normal lighting to the lighting of melatonin, Tony U above process may be inconvenient tree users. Therefore, in order not to make the user always intended 到转换的情况下给用户提供最佳的睡眠照明环境,有必要提供一种能够自动检测用户的睡眠和睡醒时间以自动执行上述照明的转换的装置。第二,关于自就寝至lj入睡开始期间身i糊态的信息还能够用于睡眠评估。评估用户的睡目民质量的一个因素是^/她入睡有多快,这称为"入睡的平稳度",并且这倉,舰测量入睡所需要的时间量(以下称为"睡目赚伏期")容易地定量评价,这需要关于用户从就寝到实际入睡需要多久的信息, 即,用户打算入睡的时间与用户实际入睡的时间之间的时间差。根据在例如日本专利申请公开文件No.H5-245148中公开的现有技术,将用户就寝的时间用作用户打算睡眠的时间。然而,由于在很多情况下用户就寝以后(他/她)可能鈕卖书或看电视,因此将用户就寝的时间看作用户打算入睡的时间经常是不适当的,并且由此计算的睡目鹏 The case of converting to provide the best environment for the user sleeping lighting, it is necessary to provide an automatic detection of the user's sleep and wake time to convert the illumination means automatically performed. Second, with regard to the bed from the sleep start lj i paste state information itself can also be used during sleep evaluation. evaluate the user's sleep mesh China quality factor is ^ / her sleep how fast, it is called "sleep smoothness", and this bin, ship measured sleep the amount of time required (hereinafter referred to as "sleeping eye make-volt period") easily quantitative evaluation, which requires the user from bed to go to sleep how long the actual information that the user intends sleep time and sleep time of actual users the difference between the time according However, since in many cases after sleeping in the prior art example, Japanese Patent application Publication No.H5-245148 disclosed, bedtime of the user as the user intends to sleep time user (his / she) may sell books or watching TV button, so the user's sleeping time as the user intends to sleep time is often inappropriate, and thus calculated to sleep head Peng 伏期可能不准确。对于上述两种应用,需要提供对用户打算入睡的时间进行方便准确地检湖啲组件。在这点上,在此所述的本发明利用了通常在睡着之前会设定闹钟或者关闭或调暗灯光的事实。即,通过将用户设定闹钟或关闭灯光或将灯光调暗至幌定照度以下的时间近似为用户打算入睡的时间,能够更加准确地确定睡眠潜伏期。 V s may not be accurate. For both applications, it is necessary to provide time for the user intends to fall asleep easily and accurately detecting GOD Lake assembly. In this regard, the invention herein utilizes generally will fall asleep before the set the alarm clock or turned off, or dim the lights in fact. That is, the user sets the alarm light on or off, or dim the lights to the illumination Asahara time is approximately the time the user intends to fall asleep, the sleep latency can be determined more accurately set. 此外,通过将灯光从正常照明转换到褪黑素照明的时间设定成比用户设定闹钟或关掉灯光或将灯光调暗到特定照度以下的时间早两小时,能够更加准确地控制灯光从正常照明转换到褪黑素照明的时间。 Further, by the illumination light from the normal illumination to the melatonin is set smaller than the user set an alarm or turn off the lights to dim the lights or a specific time earlier following two hours of illumination, the light can be controlled more accurately from conversion to the melatonin illumination normal lighting time. 此外,众所周知的是当嗣民质量改善时身体的运动减少,反之当睡眠质量恶化时身体的运动增多,因而,育巨够基于睡眠期间的身体运动来评估在一个实施方案中,采集/存储层54包括超吸收材料,所述材料具有 Further, it is known that when Si China quality improvement movement of the body is reduced, and vice versa when the sleep quality deteriorates increased movement of the body, and therefore, sterility giant be based on the body movement during sleep to assess In one embodiment, the acquisition / storage layer, 54 comprises a superabsorbent material, said material having

不小于400 xl(T7cm3.s/g,更优选不小于500 x l0-7cm3.s/g,还更优选不小于700 x 10'7cm3.s/g,特别优选不小于1,000 x 10-7cm3.s/g的专用改进的盐水流动传导率(本文称为改进的SFC),所述盐水流动传导率采用上述美国专利申请序列号11/091,255和JP 2004-105118所述的专用改进的SFC测试来测定。釆集系统的这种超吸收材料的此改进的SFC优选不超过4,000xl0-7cm3.s/g,更优选不超过3,000xl(T7cm3.s/g。 Not less than 400 xl (T7cm3.s / g, more preferably not less than 500 x l0-7cm3.s / g, still more preferably not less than 700 x 10'7cm3.s / g, particularly preferably not less than 1,000 x 10-7cm3. s / g of specific improved saline flow conductivity (referred to herein as modified SFC), the saline flow conductivity using the above-mentioned U.S. Patent application serial No. 11 / 091,255, and JP-specific modified SFC test according to 2004-105118 Determination this improved SFC collection system is preferably preclude such superabsorbent material not exceeding 4,000xl0-7cm3.s / g, more preferably not more than 3,000xl (T7cm3.s / g.

由于本发明所述的采集/存储层54基本上不含纤维素纤维,因此它可比现有技术为了类似目的所使用的吸收芯组件具有更高的密度。 Since the acquisition of the present invention / storage layer 54 is substantially free of cellulose fibers, than the prior art so that the absorbent core assembly for similar purposes used having a higher density. 适宜地,采集/存储层54可具有大于约0.3g/cm3,或甚至大于0.4g/cm3的密度。 Suitably, acquisition / storage layer 54 may be greater than about 0.3g / cm3, or even a density greater than 0.4g / cm3 of.

采集/存储层54和存储系统60也共同作用以向尿布20提供改善的穿着贴合性和舒适性。 Acquisition / storage layer 54 and storage system 60 also cooperate to provide improved fit of the diaper 20 worn and comfort. 具体地讲,包括芯28的尿布20具有可取的低厚度和裆部柔韧性。 Specifically, the core 28 of the diaper 20 comprises preferably has a low thickness and flexibility of the crotch portion. 在所述芯中采集系统50包括至少一个本发明所述的采集/ 存储层54。 The acquisition system 50 comprises at least one acquisition of the present invention / storage layer 54 in the core. 正如将认识到的那样,低厚度和挠性材料导致柔韧的芯。 As it will be appreciated as the low thickness and flexibility of the flexible core material results. 该芯在穿着者运动的全部范围内可一直更加紧密地适形于穿着者的身体。 The core over the entire range of movement of the wearer may have been more closely conform to the wearer's body. 同时此类薄的/柔韧的尿布在穿着者的衣服下也不易看见,并且可具有非常像内衣的外观。 While such thin / flexible diaper hardly seen under clothing of the wearer, and may have an appearance very much like underwear.

正如上文所注意到的,依照本发明的芯28具有所需的低厚度。 As noted above, the core 28 in accordance with the present invention has a low thickness desired. 可取的是,本发明的釆集系统50既包括釆集层52又包括釆集/存储层54。 Preferably, it precludes the collection system 50 of the present invention includes both preclude the collector layer 52 in turn comprises a set of Bian / storage layer 54. 对于此构造的芯28,当在采集层52的中心测量时,干燥芯的厚度小于约5mm。 For this configuration of the core 28, when measured at the center of the acquisition layer 52, the thickness of the dried core is less than about 5mm. 优选地,当在采集层52的中心测量时,芯28的厚度小于约4.5mm,更优选地小于约4mm。 Preferably, when measured at the center of acquisition layer 52, the thickness of the core 28 is less than about 4.5mm, more preferably less than about 4mm. 不掺入采集层52的结构体甚至更薄。 Not incorporated into the acquisition layer 52 of the structure even thinner.

应当指出的是,虽然本领域中有许多吸收结构讨论厚度,但只是据单层而不是据为尿布20形成完整芯28所必需的组合层来讨论吸收结构的厚度。 It should be noted that, although there are many discussed thickness of the absorbent structure, but only according to a single layer rather than a complete core 28, according to the necessary combination of layer thickness of the diaper 20 to the absorbent structure of the discussion in the art. 因此据信本发明的芯28的低厚度是特别有利的。 Thus, according to the low thickness of the core 28 of the present invention it is believed to be particularly advantageous. 换句话讲,芯28的低厚度为尿布20提供期望的低厚度。 In other words, the low thickness of the core 28 of the diaper 20 to provide a desired low thickness. 即,在顶片的身体表面和底片的衣服表面之间的所有尿布部件的厚度有意义地小于现有技术尿布的厚度。 That is, the thickness of all components of the diaper between the body surface of the topsheet and a garment surface of the backsheet meaningfully less than the thickness of prior art diapers. 例如, 在一个实施方案中,包括本发明所述的芯28的尿布20具有小于约5mm 的干厚(在与芯28的前边缘29相距10cm的位置测量)。 For example, in one embodiment, the present invention includes a core 20 of the diaper 28 having a dry thickness of less than about 5mm (measured at the front edge of the core position 28 29 distance of 10cm). 优选地,尿布20 的干厚小于约4.5mm,更优选小于约4mm。 Preferably, the dry thickness of the diaper 20 is less than about 4.5mm, more preferably less than about 4mm.

本发明所述的芯28可取地也为柔韧的,以便有利于减小尿布20的堆积体积并改善其适形性。 The core 28 of the present invention desirably is also flexible, so as to help reduce the bulk of the diaper 20 and to improve the conformability. 不受理论的约束,据信如上所述的薄型构造(如所已知的那样,硬度随着厚度的增加而增加)和由热塑性材料(例如,见于已公布的美国专利申请2004/0162536 )结合的柔韧的吸收性聚合物颗粒的结合体相组合而共同作用以提供可取的柔韧性。 Without being bound by theory, it is believed thin structure as described above (e.g., as is known, the hardness increases with increasing thickness) and a thermoplastic material (e.g., found in published U.S. Patent Application 2004/0162536) binding the combination of flexible absorbent polymer particles are combined and cooperate to provide desirable flexibility. 因此,芯28可以更容易地符合不同的穿着者体形并且对穿着者的运动做出反应。 Thus, core 28 can more easily conform to different body of a wearer and to respond to movements of the wearer. 如可见于实施例1,现有技术的尿布产品在柔韧性上的可变范围很宽(当根据圓弯曲柔韧性测试评测时为4.0N至70.5N)。 As can be seen in Example 1, the prior art diaper products on the flexibility a wide variable range (When used according to the circular bending flexibility evaluation test of 4.0N to 70.5N). 将会认识到,这种柔韧性是许多因素在成品尿布产品中共同作用的结果。 It will be appreciated that such flexibility is the result of many factors working together in the finished product in a diaper. 例如,对比尿布A和B的圓弯曲柔韧性明显不同, 虽然这些尿布具有非常类似的存储系统。 For example, a circular bending flexibility diapers Comparative A and B is significantly different, although very similar storage system having these diapers. 不受理论的约束,据信该圆弯曲柔韧性的差別可归因于采集系统的差别。 Without being bound by theory, it is believed that the circular curved acquisition system attributable to differences in the flexibility of the difference. 具体地讲,对比尿布A中所用的双层采集系统具有可取的流体处理性能(例如,双层采集系统对尿液"涌流"提供实质性的临时存储,导致快速采集)。 Specifically, double-contrast acquisition system used in the diaper A having desirable fluid handling properties (e.g., double urine collection system "gush" provides a substantial temporary storage, resulting in rapid acquisition). 这些有益效果是以与对比尿布B相比实质上较小的柔韧性为代价的。 These benefits are substantially less flexibility as compared to Comparative B at the expense of the diaper. 参照实施例2,其显示本发明的芯设计保持对比芯B的大部分改善的柔韧性(本发明所述芯的〜12N与对比芯A 的〜44N),同时也提供对比芯A的可取的流体处理性能(本发明所述芯的~100秒的第三涌流采集速率与对比芯B的~200秒)。 Reference Example 2, which shows the core design of the present invention maintains the flexibility to improve the contrast most of the core B (~44N ~12N the core of the present invention and comparative core A), while also providing desirable core A comparison fluid handling properties (the core of the present invention to 100 seconds Comparative third gush acquisition rate of the core B to 200 seconds). 具体地讲,将对比尿布A的双层采集系统置换成本发明所述的存储/分配系统会提供双层系统的大部分的快速采集能力,而同时又在干燥时保持薄且柔韧以致提供对比尿布B的大部分的干燥柔韧性。 Specifically, the contrast of the diaper acquisition system A double substitution most rapid acquisition capability storage / dispensing system of the invention provides double the cost of the system, while maintaining in the dry thin and flexible so as to provide diapers Comparative most of the drying flexibility B's. 适宜的是,本发明所述的吸收芯28具有小于约13N,优选小于约12N,并且更优选小于约10N的圆弯曲柔韧性。 Suitably, the absorbent core 28 of the present invention has less than about 13N, preferably less than about 12N, and more preferably less than about 10N circle of bending flexibility. 类似地,本发明所述的吸收制品具有的圆弯曲柔韧性实质上低于可商购获得的尿布和现有技术的尿布的圆弯曲柔韧性。 Similarly, the absorbent article of the present invention has a circular bend flexibility of less than substantially circular bending flexibility of the diaper and the commercially available prior art diaper. 适宜的是,本发明所述的吸收制品在某个样本中具有小于约15N的圆弯曲柔韧性,所述样本取自裆区37中的吸收芯28的横向中心线的前方的位置。 Suitably, the absorbent article of the present invention has less than about 15N circular bending flexibility in a sample, the sample is taken from a position in front of the lateral centerline of the absorbent core 28 in the crotch region 37. 优选地,裆区37中的圓弯曲柔韧性小于约13.5N, 更优选小于约IIN。 Preferably, the circular bend flexibility of less than about 13.5 N crotch region 37, more preferably less than about IIN. 用于测定圆弯曲柔韧性的方法见于下文的测试方法部分。 A method for measuring the flexibility of a circular bend found in the Test Methods section below. 本发明的吸收芯28不仅具有上文所述的低厚度和改善的柔韧性,它们还为穿着者提供可取的流体处理性能。 The absorbent core 28 of the present invention not only has a low thickness and flexibility improvements described above, they also provide the wearer desirable fluid handling properties. 对于吸收制品,需要考虑至少两种类型的流体处理性能:流体采集和流体存储容量(例如,由采集层的超吸收材料和存储系统的超吸收材料的SFC和/或其采集速率反映出来,如本文所述)。 For absorbent articles, it is necessary to consider at least two types of fluid handling properties: fluid acquisition and fluid storage capacity (e.g., a super absorbent material over the acquisition layer and storage systems SFC absorbing material and / or reflected acquisition rate, such as herein). 吸收制品应当具有良好的流体采集性能以便快速地从吸收制品的身体表面转移含水流体,从而最小化可绕过箍和腰带而导致渗漏的游离流体。 The absorbent article should have good fluid acquisition properties of the aqueous fluid in order to quickly transfer from the body surface of the absorbent article, thereby minimizing bypass cuffs and waistbands can lead to fluid leakage free. 在本发明的情形中,采集/存储层54与采集层52共同作用(当这种采集层存在时)以提供用于容纳含水液体的"涌流,,的空隙体积,以便让存储系统60 有时间采集并永久性地存储此类流体。由于采集/存储层54包括高度可渗透的超吸收材料,因此即使在组成采集/存储层54的超吸收材料因接触含水流体而开始膨涨之后,这种空隙体积也可得到保持。流体釆集性能可使用下文在测试方法部分中所述的流体采集测试来方1更地测定。此测试测定吸收制品采集预定义体积的流体所需的时间,所述预定义体积的流体以一系列的"涌流,,递送。 In the case of the present invention, 52 cooperate acquisition / storage layer 54 and the acquisition layer (acquisition layer when such is present) to provide a void volume for containing the aqueous liquid "surge ,, in order to allow time for the storage system 60 collect such fluids and permanently stored. Since the acquisition / storage layer 54 comprises a highly permeable superabsorbent material, even in the composition of the acquisition / storage layer 54 of superabsorbent material by contacting the aqueous fluids swell begins after this maintaining void volume can be obtained. preclude fluid collection performance can be measured using a more local fluid acquisition test described below in the test methods section. this test measures the time required for the absorbent article of the fluid acquisition predefined volume, the predefined volume of fluid delivered in a series of "surge ,,. 该体积和递送速率旨在代表具体尺码的吸收制品的典型条件。 The delivery rate and volume of the absorbent article is intended to represent typical conditions of specific size. 取决于制品的尺码,采集流体的第三或第四涌流所需的时间可为采集性能的一个重要测量。 Depending on the size of the article, the time required for collecting fluid may be a third or fourth gush acquisition performance is important measure. 适宜的是,本发明所述的吸收制品具有小于约170秒,优选小于约150秒,更优选小于约130秒的第三涌流釆集速率。 Suitably, the absorbent article of the present invention has less than about 170 seconds, preferably less than about 150 seconds, more preferably less than about 130 seconds, the third gush Bian set rate. 特别优选的实施方案具有小于约100秒的第三涌流釆集速率。 Particularly preferred embodiments having less than about 100 seconds, the third gush Bian set rate. 对于较大尺码,第四涌流的采集速率也很重要。 For larger sizes, the fourth gush acquisition rate is also very important. 适宜的是,本发明所述的吸收制品具有小于约190 秒,优选小于约180秒,更优选小于约170秒的第四涌流采集速率。 Suitably, the absorbent article of the present invention has less than about 190 seconds, preferably less than about 180 seconds, more preferably less than about 170 seconds of the fourth gush acquisition rate. 具体地讲,本发明的芯28必须提供足够的存储容量以起作用,而同时又提供实质上减小的干厚和改善的柔韧性。 Specifically, the core 28 of the present invention must provide sufficient storage capacity to function, while simultaneously providing improved dry thickness and a substantially reduced flexibility. 如同样已知,吸收制品必需的吸收能力基本上由它们的预期用途来限定。 As is also known, the required absorbent capacity of the absorbent article is substantially defined by their intended use. 即,预期用于成人失禁用途的吸收制品将比预期用于婴儿的吸收制品具有更大的设计容量。 I.e., the expected use of the absorbent article for adult incontinence than predicted for infants absorbent article design having a larger capacity. 重要的是,依照本发明的吸收芯28不放弃存储适量含水流体的能力以便提供芯厚度的减少。 Importantly, in accordance with the storage capacity does not give the right amount of aqueous fluid absorbent core 28 of the present invention to provide a reduced core thickness. 考虑能力的一种方法是作为标准容量,即每单位面积的容量。 A method is considered as a standard capability capacity, i.e. capacity per unit area. 这种方法考虑到,设计用于较大穿着者的吸收制品将具有较大的设计容量和较大的芯面积以吸收沉积在其上的流体。 This approach allows for the absorbent article, designed for larger wearer will have a larger design capacity and larger core area to absorb fluid deposited thereon. 一种用于标准化容量的方法见于美国专利申请序列号11/091,255中。 A method for standardized capacity found in U.S. Patent Application Serial No. 11 / 091,255. 适宜地,依照本发明的芯28在其中包括采集存储层54的部分,具有的标准容量将为大于约0.3g/cm2。 Suitably, in accordance with the present invention, the core 28 includes a portion in which the acquisition memory layer 54, having a standard capacity will be greater than about 0.3g / cm2. 优选地,在其中包括采集存储层54的部分的标准容量大于约1.0g/cm2,更优选大于约2.0g/cm2。 Preferably, the portion including a standard capacity of the acquisition memory layer 54 is greater than about 1.0g / cm2, more preferably greater than about 2.0g / cm2. 在芯28的那些不包括采集/存储层54的部分中,标准化容量可较低。 In those portions of the core 28 does not include an acquisition / storage layer 54, the normalized capacity is low. 对于其中用于含水液体的大多数容量在裆区37内或邻近裆区37的设计。 For most of the design capacity for aqueous liquids in or adjacent the crotch region 37 crotch region 37. 适宜的是,在这些区域中的标准容量小于约0.9g/cm2,优选小于约0.5g/cm2,更优选小于约0.2g/cm2。 Suitably, the standard capacity in these areas is less than about 0.9g / cm2, preferably less than about 0.5g / cm2, more preferably less than about 0.2g / cm2. 在一个可供选择的实施方案中,芯28被设计成能在腰区36、 38之一或其两者中提供极限存储的实质性部分。 In an alternative embodiment, the core 28 is designed to be a substantial portion of the waist region, one or both of 3638 provides storage limit. 对于此实施方案,腰区36、 38之一或其两者中的标准化芯容量可等于或高于裆区37中的标准化芯容量。 For this embodiment, the waist regions 36, 38 one or both of the normalized core capacity equal to or higher than the normalized core capacity in the crotch region 37. 例如这种腰区标准化芯容量可大于约1.0g/cm2,甚至大于约2.0g/cm2。 Such standardization, for example, the capacity of the waist regions of the core may be greater than about 1.0g / cm2, even greater than about 2.0g / cm2. 对于此实施方案,裆区37的面积小于上文所述的实施方案中的面积,在那里用于含水液体的容量的本体处在裆区37内或邻近裆区,并且采集/存储层54可延伸进腰区36、 38中。 For this embodiment, the area of ​​the crotch region 37 is smaller than that of the above embodiment, where the capacity for aqueous liquids is within the body adjacent the crotch region 37 or the crotch region, and the acquisition / storage layer 54 may be extend into the waist region 36, 38. 如将会认识到的那样,如果希望计算芯28的总容量,则可使用本领域已知的方法(例如,图象分析)来确定具有和不具有采集层54的芯28的各自的面积,并且将这些面积乘以单位面积的标准化容量,以确定具有特定尺寸的芯28的总容量。 As will be appreciated that, if desired to calculate the total capacity of the core 28, the methods known in the art may be used (e.g., image analysis) is determined with and without the acquisition layer 54 of the core area 28 of each, and multiplying the normalized capacity per unit area of ​​the area, to determine the total capacity of a particular size of core 28. 存储系统60可使用前述美国专利申请序列号10/776,839中所述的方法来适宜地生产。 Storage system 60 may use methods described in U.S. Patent Application Serial No. 10 / 776,839 to the suitably produced. 采集/存储层54可使用实质上与用来生产存储系统60的方法相同的方法生产。 Acquisition / storage layer 54 may be produced using substantially the same methods used to produce storage system 60. 主要区别在于:不提供粗糙表面以便提供接合区域,在这些区域中粘合剂直接接触基底层,如美国专利申请序列号10〃76,839所述;而是提供配有一系列"口袋,,的沉积转筒,这些"口袋,,的形状和体积实质上由采集/ 存储层54的希望的形状和体积所限定。 The main difference is that: in
