<First Embodiment>
FIG. 1 is a perspective view when connecting the front and rear waist regions of a disposable diaper as an example of a disposable wearing article according to the present invention, FIG. 2 is a plan view seen from the skin facing surface of the developed diaper, and FIG. 3 is a diaper 4 is an end view taken along the line IV-IV in FIG. 2, FIG. 5A is a view before the side panel regulating member is cut along the cutting guide line, and FIG. 5B is the regulating member. It is a figure after cut | disconnecting along a cutting | disconnection guide line. FIG. 1 is a diagram in which a regulating member is cut along a cutting guide line and front and rear waist regions are connected, and FIGS. 2 to 4 are diagrams showing a state before the regulating member is cut.

  As shown in FIG. 1, the diaper 1 has a longitudinal direction Y and a lateral direction X, a front waist region 11 and a rear waist region 12, a crotch region 13 positioned between these front and rear waist regions 11, 12, It has front and rear end edges 14 and 15 extending in the direction X, and both side edges 16 extending in the longitudinal direction Y. The diaper 1 can fix the diaper 1 to a wearer's body while forming a waist opening by connecting the hook element 72 of the fastening system provided in the rear waist region 12 to the front waist region 11.

  As shown in FIG. 2, the diaper 1 has a virtual vertical center line PP that bisects the dimension in the horizontal direction X, and is substantially symmetric with respect to the virtual vertical center line PP. Some of the same components that are made symmetrical are omitted in the drawings.

  As shown in FIGS. 2 to 4, the diaper 1 includes a liquid-permeable surface sheet 20 positioned on the skin facing surface, and a back sheet 30 positioned on the non-skin facing surface (clothing side) on the opposite side. The body fluid absorber 40 positioned between the front and back sheets 20 and 30 and the liquid-impervious or liquid-impervious leak-proof sheet 50 positioned between the absorber 40 and the back sheet 30 are included. A pair of containment sheets 60 that are spaced apart in the horizontal direction X and extending in the vertical direction Y are disposed on the skin facing surface of the topsheet 20. The top sheet 20 and the back sheet 30 form the chassis 10 of the diaper according to the embodiment.

As the surface sheet 20, for example, a hydrophilic spunbond fiber nonwoven fabric or point bond fiber nonwoven fabric having a mass of about 15 to 35 g / m ² , preferably about 18 to 23 g / m ² can be used. As the back sheet 30, for example, a spunbond / meltblown / spunbond (hereinafter referred to as SMS) non-woven fabric or a spunbond non-woven fabric having a mass of about 10 to 30 g / m ² can be used.

As the containment sheet 60, for example, an SMS fiber nonwoven fabric having a mass of about 10 to 30 g / m ² can be used. The front and rear end edges 61 and 62 of the containment sheet 60 are overlapped so as to coincide with the front and rear end edges 21 and 22 of the surface sheet 20, and are joined to each other by a known joining means such as a hot melt adhesive (not shown). The proximal edge portion 63 of the containment sheet 60 overlaps both side edge portions 33 of the back sheet 30 and is joined to each other by a known joining means such as a hot melt adhesive (not shown). The distal edge portion 64 of the containment sheet 60 overlaps the top sheet 20 in a state where the diaper 1 is extended in the longitudinal direction Y. An elastic body 65 extending in the longitudinal direction Y is attached to the distal edge portion 64 so as to be retractable in an extended state. Due to the contraction of the elastic body 65, the distal edge 64 is separated from the surface sheet 20 toward the wearer's skin side and closely contacts the skin, and excrement such as stool is contained inside the containment sheet 60.

  The absorber 40 functions as long as it is located at least in the crotch region 13. In this embodiment, the absorber 40 extends from the crotch region 13 to the front and rear waist regions 11 and 12 and excretes urine or the like in a relatively wide range. It is designed to absorb things. The absorbent body 40 is formed by covering a liquid-absorbent core material with a liquid-diffusible covering sheet such as tissue paper. Wood fluff pulp, superabsorbent polymer particles, or a mixture thereof can be used as the core material. The core material and the covering sheet can be joined to each other using a known joining means such as a hot melt adhesive (not shown).

  The leak-proof sheet 50 disposed between the absorber 40 and the back sheet 30 may be made of a liquid-permeable, preferably liquid-impervious and breathable plastic film. The area of the leak-proof sheet 50 is larger than that of the absorber 40. Therefore, excrement such as urine absorbed by the absorber 40 can be prevented from leaking outside the diaper 1. The leak-proof sheet 50 can be bonded between the covering sheet of the absorber 40 and the back sheet 30 by using a known bonding means such as a hot melt adhesive (not shown).

  A leg elastic body 51 and a waist elastic body 52 are attached to the surface of the leak-proof sheet 50 opposite to the surface facing the back sheet 30. The leg elastic body 51 and the waist elastic body 52 are joined to at least one of the leak-proof sheet 50 and the containment sheet 60 by a known joining means such as a hot melt adhesive (not shown). The leg elastic body 51 extends in the longitudinal direction Y along the side edges 16 in the crotch region 13 and is attached to the longitudinal direction Y so as to be contracted in an extended state. The leg elastic body 51 has a first end edge 51a located on the front waist region 11 side and a second end edge 51b located on the rear waist region 12 side. The second end edge 51 b extends to the rear waist region 12. The waist elastic body 52 extends in the lateral direction X along the rear end edge 15 in the rear waist region 12 and is attached to the lateral direction X so as to be contractable in an extended state. As the leg elastic body 51 and the waist elastic body 52, a plurality of string-like or strand-like elastic bodies can be used.

  A pair of side panels 70 are attached to both side edges 16 of the rear waist region 12 of the chassis 10. The side panel 70 includes an extending member 80 that can extend in the lateral direction X, and a restricting member 90 that is attached to the extending member 80 so as to restrict extension of the extending member 80. The extending member 80 includes a first sheet 81 located on the skin facing surface, a second sheet 82 located on the non-skin facing surface, and a plurality of side panel elastic bodies 83 attached between these sheets.

The first and second sheets 81 and 82 have substantially the same shape and size, and for example, an SMS fiber nonwoven fabric having a mass of about 10 to 30 g / m ² can be used. They are joined together by means. These first and second sheets 81 and 82 are substantially non-extensible fiber nonwoven fabrics. "Substantially non-extensible" means that the diaper 1 is used around the waist opening when the diaper 1 is worn even if it is pulled with a normal force at least in the lateral direction X without having elastic elasticity. The one that does not change the dimension that affects the setting of the dimension. Incidentally, even if the entanglement or welding of the fibers of the nonwoven fabric is slightly unwound by the normal force and may be slightly stretched inelastically, this is assumed to be in a substantially non-stretchable range. This is because the dimension setting is not affected.

  The side panel elastic body 83 is attached in such a manner that it can contract in the extended state in the lateral direction X and is spaced apart in the longitudinal direction Y. By attaching the side panel elastic body 83 in this way, the extending member 80 can be elastically expanded and contracted. As the side panel elastic body 83, for example, a string-like or strand-like elastic body of 470 to 940 dtex is used. These elastic bodies are elongated in the lateral direction X, for example, about 2 to 3 times, and the pitch in the longitudinal direction Y is about Can be attached at 5-15 mm. In this embodiment, the side panel elastic body 83 of about 620 dtex is used, the pitch in the vertical direction Y is arranged at about 10 mm, and the side panel elastic body 83 is extended by about 2.6 times in the horizontal direction X and attached.

A regulating member 90 is laminated on the second sheet 82 of the extending member 80 on the surface opposite to the surface facing the first sheet 81. The regulating member 90 is made of a substantially non-extensible fiber nonwoven fabric. As the regulating member 90, for example, a spunbond fiber nonwoven fabric, an SMS fiber nonwoven fabric or the like having a mass of about 40 to 60 g / m ² can be used. As shown in FIG. 4, the regulating member 90 is joined to the second sheet 82 via joint portions 91 and 92 that are separated in the lateral direction X and extend in the longitudinal direction Y. The joint portions 91 and 92 are formed at a position where the side panel elastic body 83 does not overlap, that is, a position where the elastic body does not exhibit the stretching force. In addition, when the side panel elastic body 83 is cut back in the attachment process, it can also be formed so that it may overlap with the edge part which does not exhibit a stretching force. In the region where the elastic force of the side panel elastic body 83 is exerted, the second sheet 82 is wrinkled. However, when the joining portions 91 and 92 are formed so as to overlap the wrinkles, the second sheet 82 and the second sheet 82 are restricted. The joining force with the member 90 may be reduced. However, in this embodiment, since the joint portions 91 and 92 are formed at positions where the contraction force of the side panel elastic body 83 is not exerted, it is possible to prevent a reduction in the joint force. As the joining portions 91 and 92, known joining means such as a hot melt adhesive can be used.

  Note that the above description does not prevent the joining portions 91 and 92 from being formed at a position where the contraction force of the side panel elastic body 83 is exerted, and may be formed at a position where they overlap. In that case, the joining strength of the joining portions 91 and 92 can be increased so that the second sheet 82 and the regulating member 90 do not peel off. Moreover, although the case where the 2nd sheet | seat 82 and the control member 90 are joined directly is demonstrated, the case where another sheet | seat is further interposed between these sheets is included. In this case, the joining portions 91 and 92 are formed on the second sheet 82 or the regulating member 90 via another sheet. In other words, the extending member 80 may include other sheets in addition to the first and second sheets 81 and 82, and the regulating member 90 may include other sheets in addition to the non-extensible fiber nonwoven fabric. May be included.

  The inner edge 90 c of the regulating member 90 is fixed between the back sheet 30 and the containment sheet 60 by a joining means (not shown), and extends from the side edges 16 of the chassis 10 toward the outside in the lateral direction X. A hook element 72, which is a fastening means, is attached to the outer edge 90 d of the regulating member 90 via a tab sheet 71.

  By hooking the hook element 72 to the fiber nonwoven fabric of the back sheet 30 of the front waist region 11, the front and rear waist regions 11, 12 are connected, and the pants-type diaper 1 can be worn by the wearer. The hook element 72 of this embodiment is the second connecting element according to the present invention, and the back sheet 30 in the front waist region 11 is the first connecting element according to the present invention. By using the back sheet 30 as the first connecting element, the hook element 72 can be fixed to any of the non-skin facing surfaces of the chassis 10. That is, the entire area of the front waist region 11 can be used as the first connecting element. Since the hook element 72 can be connected in a wide range of the front waist region 11, the front and rear waist regions 11, 12 can be connected in close contact with the wearer according to the wearer's body shape and body condition. Moreover, since a separate member is not required by using the back surface sheet 30 as the first connecting element, the manufacturing cost can be reduced accordingly.

  FIG. 5 is a view when the side panel 70 is viewed from the non-skin facing surface. As shown in FIG. 5A, in the regulating member 90, a cutting guide line 93 extending in the vertical direction Y is formed between the joint portions 91 and 92. The cutting guide wire 93 is configured by a plurality of through holes 94 that penetrate the regulating member 90 in the thickness direction and are intermittently arranged in the longitudinal direction Y. The through holes 94 respectively extend from the front and rear end edges 90a, 90b of the regulating member 90 toward the inside in the vertical direction Y, and in this embodiment, are arranged in a straight line. In this embodiment, the through hole 94 is a slit extending in the vertical direction Y. By forming a plurality of through holes 94 in this way, so-called perforations can be formed, and the regulating member 90 can be cut along the cutting guide line 93.

  In the state shown in FIG. 5A, the regulating member 90 is joined so as to overlap the second sheet 82 when the extending member 80 is contracted. Therefore, even if the extension member 80 is to be extended, the extension of the extension member 80 is restricted by the restriction member 90 when the restriction member 90 is not cut along the cutting guide line 93.

  As shown in FIG. 5B, when the regulating member 90 is cut along the cutting guide line 93 and is separated in the lateral direction X, the extending member 80 is exposed therebetween. Since the extending member 80 is pulled so as to be separated in the lateral direction X via the joint portions 91 and 92, it can be elastically expanded in the lateral direction X.

  In the diaper 1 as described above, when the diaper 1 is used for a wearer with a thin waist, the hook element 72 is not cut without cutting the restricting member 90, that is, in the state of FIG. It can be connected to the front waist region 11 and worn by the wearer. When used for a wearer with a thick waist, the regulating member 90 is cut, that is, after the hook member 72 is connected to the front waist region 11 after being brought into the state of FIG. Can be worn. Thus, since the aspect of the side flap 70 can be selected according to a wearer's body shape, the diaper 1 can be closely_contact | adhered with respect to various wearers. In addition, when the regulating member 90 is cut and used, the diaper 1 is more closely attached to the wearer due to the expansion and contraction of the extending member 80. Further, since the pair of side flaps 70 are attached to both side edges of the chassis 10, only one of the regulating members 90 can be cut and used without cutting the other.

  Since the cutting guide wire 93 is formed between the front and rear end edges 90a and 90b of the restricting member 90, for example, for a body-shaped wearer in which only the abdomen protrudes greatly, the vicinity of the rear end edge 90b By cutting only the cutting guide wire 93 of the extension member 80 so that stretchability is expressed in the vicinity of the rear end edge of the elongated member 80, that is, in the vicinity of the waist opening, the diaper 1 can be more closely attached to the wearer's body. it can. In addition, for a wearer with a body shape that has a thin waist and a large buttocks, only the cutting guide wire 93 in the vicinity of the front end edge 90a is cut, and the stretchability is in the vicinity of the front end edge of the elongated member 80, that is, in the vicinity of the leg opening. It can also be expressed. By forming the through hole 94 intermittently in the cutting guide wire 93, the cutting guide wire 93 can be cut halfway as described above.

The cutting guide wire 93 is a case where the cutting guide wire 93 is cut halfway in the longitudinal direction Y, and even when the cutting guide wire 93 is further cut by the wearer's movement during wearing, Since the extending members 80 are arranged so as to overlap with each other, the adhesiveness of the diaper 1 to the wearer is not impaired by cutting. Further, even when the cutting guide wire 93 is cut carelessly, the cutting guide wire 93 is formed on the side panel 70, which may affect the absorbability and the touch of the diaper 1. Absent. If the cutting guide wire 93 is formed in any one of the chassis 10, it may be cut carelessly to make the wearer feel uncomfortable or absorbed by the absorber 40 disposed in the chassis 10. It may affect the sex and induce leakage of body fluids such as urine.
Since the regulating member 90 is disposed on the non-skin facing surface of the elongated member 80, the cut surface of the regulating member 90 does not contact the wearer's skin, and irritation due to contact can be prevented in advance.

  In the cutting guide wire 93, the strength when the regulating member 90 is cut can be variously changed. For example, while the diaper 1 is worn, the regulating member 90 can be cut along the cutting guide line 93 in accordance with the movement of the wearer, or the cutting guide line 93 is held between both hands, to some extent. It can also be made impossible to cut unless it is pulled with the force of. The strength at the time of cutting can be adjusted by the dimension in the longitudinal direction Y of the through-hole 94 or the dimension between the through-holes 94, and can also be adjusted by the type of the fiber nonwoven fabric used as the regulating member 90. . The dimension in the longitudinal direction Y of the through hole 94 can be about 3 to 22 mm, and the dimension in the longitudinal direction Y of the non-through portion between the through holes 94 and 94 can be about 0.2 to 2 mm. In this embodiment, the size of the through hole 94 is about 9 mm, and the size of the non-through portion is about 1 mm. The dimensions of the plurality of through holes 94 can all be equal, for example, the front end edge 90a side can be made larger and the rear end edge 90b side can be made smaller. If the dimension between the through holes 94 is the same, the larger the dimension of the through hole 94, the easier it is to cut along the cutting guide line 93. Therefore, when the dimension of the through hole 94 is reduced on the rear end edge 90b side, it is difficult to cut on the rear end edge 90b side. Since the rear edge 90b forms part of the leg opening, if the rear edge 90b is easily cut, the cutting guide line 93 may be cut carelessly due to the movement of the wearer's leg. This can be prevented by reducing the size of the through hole 94 on the rear end edge 90b side.

  When a fiber nonwoven fabric is used as the regulating member 90, it can be used so that the fibers are oriented in the longitudinal direction Y. By orienting the fibers in the longitudinal direction Y and forming the through holes 94 so as to extend in the longitudinal direction Y, the regulating member 90 can be easily cut along the cutting guide lines 93.

  The side panel 70 continuously extends from the rear end edge 15 to the crotch area 13 in the rear waist region 12, and has a dimension in the longitudinal direction Y of about 180 to 300 mm from the front end edge 70a to the rear end edge 70b. 240 mm (see FIG. 2). Further, the dimension of the rear waist region 12 in the longitudinal direction Y is about 260 to 320 mm, and in this embodiment, it is about 281.8 mm. The dimension of the front waist region 11 in the longitudinal direction Y is about 170 to 240 mm, and in this embodiment, about 193.5 mm. The longitudinal dimension Y of the front and rear waist regions 11 and 12 is a dimension from the front and rear end edges 14 and 15 of the chassis 10 to the boundary with the crotch region 13 where the lateral dimension X is reduced. Since the side panel 70 extends in substantially the entire region in the longitudinal direction Y in the rear waist region 12, it is formed not only by the waist opening formed by the front and rear end edges 14 and 15 but also by the side edge 16 of the crotch region 13. Even in the vicinity of the leg opening, the diaper 1 can be brought into close contact with the wearer. Furthermore, since the side panel 70 is made larger than the dimension in the vertical direction Y of the front waist region 11, the side panel 70 can be connected in the whole area of the front waist region 11 in the vertical direction Y, and the front waist region 11 The whole can be brought into close contact with the wearer. The side panel 70 may be disposed only on the rear edge 15 side or the crotch region 13 side in the rear waist region 12, or a plurality of side panels separated in the longitudinal direction Y are disposed. May be.

  A leg elastic body 51 is attached to the crotch region 13 of the diaper 1, and the second end edge 51 b is located on the inner side in the lateral direction X of the side panel 70. That is, the second end edge 51 b of the leg elastic body 51 is sandwiched between the pair of side panels 70, the virtual extension line extending in the lateral direction X connecting the front end edges 70 a of the pair of side panels 70, and the leg elastic body 51. And intersect. With this positional relationship, when the side panel 70 is pulled outward in the lateral direction X and connected to the front waist region 11, the second end edge 51b of the leg elastic body 51 is also moved outward in the lateral direction X. The both side edges 16 of the chassis 10 to which the leg elastic body 51 is attached are in close contact with the wearer's legs.

  A waist elastic body 52 extending in the lateral direction X along the rear end edge 15 is attached to the rear waist region 12 of the chassis 10. Therefore, the waist opening of the diaper 1 is brought into close contact with the wearer by the elasticity of the waist elastic body 52 even when the regulating member 90 is not cut along the cutting guide line 93 and elastic expansion and contraction is not expressed. Can do. The waist elastic body 52 only needs to be attached to at least one of the front and rear waist regions 11 and 12. Moreover, although the cutting | disconnection guide wire 93 shall be comprised by the some through-hole 94, if it makes the regulation member 90 cut | disconnected, it will not be restricted to this. For example, the cutting guide wire 93 may be formed by melting the regulating member 90 by heating or pressurization and making it easier to cut than other parts, or having a thickness dimension smaller than other parts.

In this embodiment, the extension member 80 is elastically stretchable by attaching a strand-like or string-like side panel elastic body 83 between the non-extensible first and second sheets 81 and 82. However, the present invention is not limited to this. For example, a fiber nonwoven fabric that can be elastically stretched by using a stretchable film, a stretchable fiber nonwoven fabric, or the like can also be used. Moreover, although the substantially non-stretchable fiber nonwoven fabric is used as the regulating member 90, it is not limited to non-stretchability as long as it is smaller than the elongation rate of the elongated member 80. That is, if the elongation rate of the regulating member 90 is smaller than the elongation rate of the elongated member 80, even if the regulating member 90 is elongated before cutting the cutting guide wire 93, the elongated member 80 is elongated, but the elongation is somewhat. This is because it can be regulated.
The joining portions 91 and 92 are formed of a hot melt adhesive, but the regulating member 90 can be joined to the extending member 80 by heat welding such as heat sealing or sonic sealing.

  Although the back sheet 30 in the front waist region 11 is used as the first connecting element, a loop element or the like can be attached to the front waist region 11 separately. When a loop element or the like is attached to the back sheet 30 as the first connecting element, a breathable plastic sheet or the like can be used as the back sheet 30. When the back sheet 30 is not used as the first connecting element, the chassis 10 does not have the back sheet 30, and the first connecting element can be formed on the leakage preventing sheet 50. Moreover, although the hook element is used as a 2nd connection element, if the connection with the non-skin opposing surface of the front waist region 11 is possible, what is normally used in this kind of field | areas, such as an adhesive tape, will be used. be able to. When an adhesive tape or the like is used as the second connection element, for example, a plastic sheet or the like can be used as the first connection element. In this case, the leakage preventing sheet 50 can also be used as the first connecting element corresponding to the adhesive tape. The first connecting element can be attached to a part of the front waist region 11 or can be attached so as to be positioned on almost the entire front waist region 11.

In the second sheet 82 of the extending member 80, a display element is formed on the surface facing the regulating member 90 by an illustration or a character, and when the regulating member 90 is cut along the cutting guide line 93, the display element is It can also be made visible. That is, the portion of the second sheet 82 hidden by the regulating member 90 can be used as a design display unit.
In this embodiment, the side panel 70 is disposed in the rear waist region 12, but may be disposed in the front waist region 11.

  In this embodiment, the diaper 1 for adults is described as an example. However, for example, it can be applied to a diaper for infants. In that case, the dimension in each structure of a diaper can be changed suitably, and a wearer can be adapted.

<Second Embodiment>
FIG. 6 is a diagram showing the second embodiment, and is the same diagram as FIG. 4 of the first embodiment. However, in FIG. 6, the side panel 70 is enlarged and the absorber 40 is omitted. 6A shows a state before the cutting guide wire 93 is cut, and FIG. 6B shows a state after the cutting guide wire 93 is cut. In this embodiment, the elongated member 80 uses a substantially non-extensible fiber nonwoven fabric. Since other configurations are the same as those of the first embodiment, detailed description thereof is omitted.

  The extending member 80 is joined to the regulating member 90 with a part thereof being loosened in the lateral direction X between the joining portions 91 and 92. Therefore, when the cutting guide wire 93 of the restricting member 90 is cut, the extending member 80 can extend in the lateral direction X by the loosened amount. Since the extending member 80 can be formed using a single sheet, the number of parts can be reduced as compared with a case where another configuration is required. In the second embodiment, an elastically expandable member 80 as shown in the first embodiment can also be used. By further loosening the elastically expandable / contractible extension member 80 in the lateral direction X and joining it to the restriction member 90, the dimension in the lateral direction X of the restriction member 90 joined to the extension member 80 can be reduced. Accordingly, the material cost can be reduced.

  7 to 9 illustrate other variations of the cutting guide wire 93, respectively. According to the variation shown in FIG. 7, the cutting guide line extends from the front end edge 90a of the restricting member 90 in the longitudinal direction Y inward and from the rear end edge 90b to the longitudinal direction Y inward. A second cutting line 93b. The first and second cutting guide lines 93a and 93b extend substantially in parallel without crossing each other. In such a side panel 70, even when only one of the first and second cutting guide lines 93a and 93b is cut and used, the side panel 70 is not further broken inward in the longitudinal direction Y. Therefore, the diaper 1 suitable for a case where the side panel 70 is partly cut in the longitudinal direction Y and the others are not to be cut can be obtained. In this variation, the first cutting line 93a is located on the inner side in the horizontal direction X, and the second cutting line 93b is located on the outer side in the horizontal direction X, but this is not restrictive.

  According to the variation shown in FIG. 8, the cutting guide line 93 is inclined from the rear end edge 90 b toward the front end edge 90 a toward the lower right of the drawing. That is, it is inclined so as to intersect the virtual vertical center line PP. In the example shown in the figure, the waist opening tends to expand greatly because it is inclined toward the waist opening, that is, toward the rear end edge 90b, so that the waist opening is easy to expand. Can be suitably used for a wearer having a large size. Further, the cutting guide line 93 can be inclined from the rear end edge 90b toward the front end edge 90a toward the lower left of the drawing. In such a case, it can be suitably used for a wearer whose buttock size is larger than that of the waist. The inclination direction and the inclination angle of the cutting guide line 93 can be changed as appropriate.

  According to the variation shown in FIG. 9, the cutting guide line 93 can be formed in a waveform or zigzag shape that is alternately bent so as to intersect the virtual vertical center line PP. By not cutting the cutting guide wire 93 into a straight line, it becomes easy to cut halfway in the longitudinal direction Y. That is, when the regulating member 90 is cut along the cutting guide line 93, if this is a straight line, it is difficult to interrupt the cutting at a desired position, and it may be broken more than necessary or worn. There is a possibility that breakage may progress. However, by making the cutting guide wire 93 corrugated or zigzag, it is possible to prevent the breakage from proceeding more than necessary.
