Transverse divider 38 has two ends that are transversely separated. are doing.     Each of the two ends of the upstanding transverse partition 38 is connected to one of the barrier leg cuffs 32. They are joined to form an H shape. The transverse partitions 38 are It is disposed on the body facing surface and extends outwardly therefrom to extend the body facing surface of the front sheet 24. There is a sudden discontinuity inside. The transverse partition 38 is located in the rear portion 33 of the diaper 20. Of the diaper 20 is prevented from moving toward the front part 31 of the diaper 20. As shown, preferably the transverse partition 38 is generally straight and straight. Linear, can be traversed, and preferably the transverse center of the diaper 20 It is parallel to the line TT. If desired, the transverse divider 38 is It can even coincide with one of the 20 transverse centerlines TT.     With reference to FIGS. 2-3, the transverse divider 38 may be an adhesive or an art form. By other joining means, as is well known in US Pat. In particular, it has a base edge 43 joined to its body-facing surface. Transverse direction The partition 38 has a vector element in the Z direction and has a trailing edge from the plane of the diaper 20. It extends outward toward 42.     A table in which the transverse partition 38 is upright and is directed outward of the table sheet 24 May rise in the Z direction on the plane of the plane to an effective height H remote from said plane. is important. The effective height H is the length of the fecal material while the diaper 20 is being worn. Must be sufficient to provide a sudden discontinuity to impede head movement. The front sheet 24 has wrinkles and rugs. , Undulations, or other planarity If they have deviations from these, they are If it is not recognized that the position of the transverse partition 38 should be considered No. Otherwise, such deviation from flatness in the front sheet 24 Reduces the effective height H of the trailing edge 42 of the partition 38 on the front sheet 24, Not disturb the movement of the sufficiency.     As used herein, the “effective height” is directed outward of the front sheet 24. The distance in the Z direction from the plane of the surface to be extended to the trailing edge 42 of the transverse partition 38. Effective height The height H is measured in the Z direction while the diaper 20 is resting on a horizontal surface, Allows the induced contraction to occur, thereby changing the condition during use. Is simulated. The trailing edge 42 of the transverse partition 38 is preferably at least 1. 5 centimeters, more preferably at least 2. 5 centimeters, And preferably at least about 3. 5 cm, body to face table 24 It has an effective height H on the surface.     As shown in FIG. 3, the transverse partition 38 is preferably of the diaper 20. Is not perpendicular to the plane, but is instead placed in an angular relationship with it As a result, the trailing edge 42 of the upright transverse partition 38 is located behind the diaper 20. It is directed towards the part 33 and the rear waist edge. This arrangement allows the pressure of the fecal material to Helps seal transverse partition 38 against the body and crosses transverse partition 38 Provides the advantage of minimizing fecal material leakage. The arrangement is further The vertical force required to maintain contact with the user's body at the transverse partition 38 Minimize.     Transverse divider 38 can be made of a water-permeable material, but is preferably a water-impermeable material.

Suitable materials for the transverse partition 38 include a breathable composite laminate, an elongated Lum, non-woven materials, and laminates of these. The transverse partition 38 is generally Dreyer et al. ) For September 10, 1996 In accordance with the teachings of commonly assigned U.S. Patent No. 5,554,142. It can be made in general and the description of this US patent is hereby incorporated by reference. It is incorporated by reference in the description of the present application.     The transverse partition 38 is oriented generally transversely. Roughly crosswise That is, the transverse partition 38 is positioned with respect to the transverse centerline TT of the diaper 20. This means that they are substantially parallel. The transverse partition 38 is curved and Is still believed to be oriented transversely by ordinary technicians It has been recognized that. Transverse divider 38 is attached to diaper 20 at the proximal end, and Preferably, it is joined to the front sheet 24 of the diaper 20. 38 of transverse partitions Various proximal ends are joined to other components of the diaper 20, such as the backing sheet 26. Configurations are possible and are within the scope of the invention described and claimed herein. Non-departure is understood by those of ordinary skill.     Transverse dividers 38 are joined to each of the barrier leg cuffs 32. Transverse partition Each of the barrier leg cuffs 32 is preferably at a transverse end of the transverse partition 38. Is joined to. By joining the transverse divider 38 to the barrier leg cuff 32, An H-shaped pattern is formed. This H-shaped pattern adheres in the rear portion 33 of the diaper 20. This prevents any fecal material from moving to the front 31 of the diaper 20. Fecal matter Cleaning work for the caretaker by enclosing it in the rear part 33 of the diaper 20 To facilitate. Fecal material is spread over such a large surface area of the wearer Without and especially well away from the genitals.     Transverse divider 38 is joined to each of barrier leg cuffs 32 at attachment line 44. ing. The attachment line 44 has a projection on the plane of the diaper 20. Diaper 20 The projection of the attachment line 44 on the plane is deviated as it approaches one of the waist edges. FIG. As shown therein, the attachment line 44 preferably extends as it approaches the front waist edge. Branch. Branching toward the front waist is better than branching toward the back waist. Preferably, the barrier leg cuff 32 is offset at the distal edge 42 of the transverse partition 38. This is because they are closest to each other and to the longitudinal center line LL. Transversal partition 3 The proximal end 42 of 8 is oriented in a cornering relationship with the front sheet 42, The diaper 20 is cornered toward the rear portion 33.     Instead, the attachment line 44 is oblique, i.e., non- It is also conceivable to arrange them in a parallel, relationship. The mounting wire 44 is When protruding above the plane of the diaper 20, in any longitudinal direction, If the theoretical extension intersects the longitudinal centerline LL, the longitudinal centerline L It is considered to be oblique with respect to -L. Preferably, the attachment line 44 is Deviates from the longitudinal centerline LL as it approaches the front waist edge of the To     Referring to FIG. 4, a transverse divider 38 is well known in the art. Can be attached to the barrier leg cuff 32 by any joining means . Suitable bonding means include heat sealing, adhesive bonding, ultrasonic welding, and preferably self-sealing. Includes autogenous bonding. Especially suitable self Autogenous bonding technology was introduced on April 24, 1990. Ball et al. ) Issued and transferred in common U.S. Pat.

Incorporated during loading.     Attachment lines 44 have either individual bonding locations or continuous bonding I can do it. Individual bonding locations are preferred, but because of the resulting The diaper 20 is generally flexible, and thus a continuous bonded More comfortable for the user than a similar diaper 20 formed by score lines Because. However, individual bonding locations have not been selected for the attachment lines 44. According to this, the individual adhesion sites are the ones where fecal material, especially low-viscosity fecal material, It must not be so far away that it passes through and enters the front 31 of the diaper 20.     Although the attachment line 44 can be curved, the attachment line 44 is straight. It is preferably a line. If a curved attachment line 44 is selected, The curved or curved attachment line 44 minimizes the volume available for occupation of fecal material. To be large, it is recessed towards the longitudinal centerline LL. Taking a curve If the attachment line 44 is selected, the curved attachment line 44 is preferably substantially circular. And has a radius of curvature that is approximately the length of the base edge 43 of the transverse partition 38. You.     Referring to FIG. 1, the attachment line 44 can project above the plane of the diaper 20. When the attachment line 44 projects above the plane of the diaper 20, the theoretical The extension forms an included angle A. Each of the attachment lines 44 emits one ray having an included angle A. Form. Preferably, the longitudinal center line LL bisects the included angle A. Mounting wire If 44 is curved, theoretically between the ends of the main part of the attachment line 44 Is used in defining the projection of the diaper 20 on the plane. Included angle A is 60 To 150 degrees, and preferably about 70 to 130 degrees, And in the range of 80 to 100 degrees.     A plurality of evenly parallel bonding locations may be provided by the barrier leg Can be used to join each of the feet 32. Such an arrangement If selected, the mounting line 44 thus projecting on the plane of the diaper 20 is And attachment lines for controlling the position of the transverse partition 38 relative to the barrier leg cuff 32. Generally, although not always necessary, the longitudinal center line L- The mounting line 44 disposed closest to L is regulated, and the included angle A is regulated. Must be used to determine Which mounting positions are regulated by individual bonding If it cannot be determined whether or not the line 44 is formed, or if a plurality of attachment lines 44 are obstructed. If restricting the attachment of the transverse partition 38 to the wall leg cuff 32, then Any protrusions of any combination of the attachment lines 44 on the plane of the diaper 20 may be included. It can be used to determine the angle A.     As mentioned above, preferably the transverse partitions 38 are angulated with respect to the face sheet 24. Are placed in a relationship. More preferably, the transverse partition 38 is located at the rear of the diaper 20. 33 is angled.     The included angle A between the attachment lines 44 defines the angle between the transverse partition 38 and the front sheet 24. It changes inevitably as the relationship changes. The determined angle A is also The difference in the length of the facing partition 38 and the difference in the effective height H of the transverse partition 38 Change to accept. Generally, the effective height H of the transverse partition 38 increases. And the angulation relationship between the transverse partition 38 and the front sheet 24 remains constant. As a result, the included angle A of the attachment line 44 should remain constant. Transverse partition The length in the transverse dimension of 38 is measured at its proximal end 43 and increases. In addition, the included angle A between the attachment lines 44 must generally be reduced. Also The angle between the transverse partition 38 and the front sheet 24 approaches 90 degrees, ie As the directional divider 38 becomes more perpendicular to the front sheet 24, the attachment line 44 The included angle A between them must increase. Such a change is caused by the transverse partition 38 Reaching their full height without limiting the capacity of the barrier leg cuffs 32, the best sealing Necessary to ensure that     The aforementioned range of included angles is for an infant wearer weighing 16 to 28 pounds Has been determined to be appropriate for diapers 20 that fit in the range Partition 38 has a length at base edge 48 of approximately 51/2 inches, approximately 1. 125 inch The length between the barrier leg cuffs 32 at the base edge 48 and on the front sheet 24 of approximately 2 inches Relationship between the front sheet 24 having an effective height H of about 64 degrees and about 64 degrees Has been maintained. The relationship forming the angle of the transverse partition 38 with respect to the front sheet 24 Are described in Roe et al. ) Filed on June 18, 1996 And commonly assigned U.S. Patent Application Serial No. 08 / 664,603.
