Definitions

  • the present invention relates to a male incontinence guard (hereinafter referred to as male incontinence guard, incontinence guard, or simply as guard).
  • the male incontinence guard is preferably disposable, i.e. it is intended for single use. More specifically, the present invention concerns a male incontinence guard which can assume more than one form, and which a user can readily adapt according to his wishes.
  • Light incontinence i.e. leakage of small amounts of urine
  • light incontinence in terms of the amount of urine leakage, it does not mean that the discomfort experienced by the person affected is insignificant.
  • the problem and its causes are different between men and women.
  • Many men who suffer from prostate problems also suffer from light incontinence. For instance, many men who have had prostate operations have encountered problems with light incontinence.
  • incontinence guards for women are better known and there are more variants to choose from.
  • the incontinence guards intended for women are customized to the female anatomy which means that these are by no means suitable for the male anatomy.
  • incontinence guards have been specially designed for male users.
  • incontinence guards used for light incontinence
  • incontinence guards available for persons suffering from heavy incontinence, i.e. incontinence guards intended for large volumes of urine.
  • incontinence guards are however unnecessarily large and awkward to wear for male users who only suffer from light incontinence.
  • incontinence guards directed to heavy incontinence are uncomfortable to wear and are extremely indiscrete under normal clothing.
  • the enclosure of the genitals can be achieved by creating a basin-like shape by means of attaching pre-stretched elastic threads in the edges of the guard.
  • a male incontinence guard is described in WO 2007/061341 .
  • the guard has a shape which is wider at the front of the guard and tapers towards the rear edge of the guard so as to allow the guard to fit comfortably in the groin region of a male wearer.
  • Another type of male incontinence guard is described in WO 2005/044166, where the incontinence product has an accordion folded structure. The structure is closed at its lower end and forms a bowl in its lower section when unfolded.
  • WO 86/06620 discloses an incontinence protector for men which has a cup- shaped portion that is formed by two flaps, separated in their flat condition. The flaps are bent in towards one another and joined together for producing in this manner a cup-shaped bottom portion. Accordingly, there is formed an upper, shield-like portion for application to the body of the user, and a lower, cup-like portion intended to bend a distance in under penis and scrotum. The incontinence protector is downwardly tapering towards the cup-shaped portion.
  • WO 98/29061 displays a male incontinence pouch intended to allow the wearer freedom of choice to determine for himself whether he wishes to apply the pouch around the penis only or the penis and scrotum.
  • a male incontinence guard which can assume more than one form, and which a user can readily adapt according to his wishes. Furthermore, it is desirable that the guard is packaged ready for use in one form and can be readily converted into another form.
  • a balance is needed between the technical function of providing a guard having various user configurations, and the requirement of providing an article that can be discretely transported. This balance is needed since men tend to experience an awkward and embarrassing feeling when exposing the guard prior to use. Hence the volume of the guard prior to use is a separate feature that deserves attention. Additionally, there is a call for a male incontinence guard which is simple in its construction and easy to use.
  • male incontinence guards which can assume more than one form also provide a greater range of fit, allowing the same product to be used under different physical activities, e.g. resting, sitting, walking and/or running. For instance, a user may prefer that his penis is held securely in place during use of the guard or alternatively that it is only loosely held by the guard, so that some movement of the penis inside the guard may take place.
  • the incontinence guard is preferably disposable, the cost of the components is also an important factor which should be taken into consideration. Bearing in mind that incontinence guards are produced in very large quantities, even a minor change of the material used for producing one incontinence guard will have a great impact on the overall material savings. Thus, yet another area of interest is to minimize the amount of material used but without limiting the functionality of the male incontinence guard.
  • the present invention concerns a male incontinence guard, said guard having a transverse (x) and longitudinal (y) direction.
  • the guard is divided by a transverse dividing line into a first region and a second region.
  • the first region has a maximum extension in the transverse direction which is greater than the maximum extension of the second region in the transverse direction.
  • the guard further comprises a liquid receiving surface and a barrier surface.
  • the guard has a first configuration and a second configuration.
  • the first region of the guard comprises a first side protection portion with a first side edge, a second side protection portion with a second side edge, and a central portion with a central portion edge.
  • the central portion is located in between the first side protection portion and the second side protection portion in a transverse direction, wherein at least a portion of the first side edge and a portion of the second side edge are each joined to at least a portion of the central portion edge by a breakable join when the guard is in the first configuration, with the liquid receiving surfaces of the first side protection portion and the second side protection portion facing the liquid receiving surface of the central portion; and wherein the breakable joins are broken when the guard is in the second configuration.
  • the surface area of the side protection portions is typically between 30-140 cm 2 , preferably between 50-120 cm 2 , and more preferably between 60-90 cm 2 .
  • the penis of the wearer is intended to be placed on the liquid receiving surface of the central portion such that the liquid receiving surfaces of the first side protection portion, the second side protection portion and the central portion partly enclose at least a part of the penis.
  • the second region is intended to be located forward on the wearer.
  • the first region is then intended to be located rearward on the wearer when the guard is being worn.
  • the first configuration provides the wearer with side protection such that urine discharged from the wearer is prevented from leaking out from the guard.
  • the first configuration provides a splash guard functioning in more than one direction; sideward by the side protection portions, downward by the joint between the side edges to the central portion edge and towards the abdomen of the wearer by the central portion.
  • the first configuration enables the penis of the wearer to stay in place when the guard is being used.
  • the first configuration is therefore particularly beneficial when the wearer is active, e.g. walking or running, and wishes to have a good protection against urine leakage.
  • the guard can be transformed into a second configuration providing the wearer with a substantially flat guard.
  • the first region is intended to be located forward on the wearer.
  • the second region is then intended to be located rearward on the wearer when the guard is being worn.
  • the second configuration enables the guard to fit comfortably in the groin region and enclose the genitals of the male user since the first region has a maximum extension in the transverse direction which is greater than the maximum extension of the second region in the transverse direction.
  • the second configuration is particularly useful for a wearer who prioritizes the aspect of comfort, i.e.
  • the second configuration provides room for the penis to be positioned in various directions and to have it freely movable in relation to the guard.
  • the second configuration can be useful for men only suffering from minor urine leakages, i.e. drip incontinence, who may not feel a need for any supporting side protection portions.
  • the second configuration may also be practical for men having reduced mobility in their hands, which is particularly common among older men. For this category of wearers it may be convenient for the wearer to be able to simply position his penis on a flat- open surface, without any need of manual dexterity.
  • a guard is provided that can assume more than one form which allows the male wearer a freedom of choice. A user can therefore readily adapt the guard according to his wishes.
  • the guard provides a greater range of fit, allowing the same product to be used under different physical activities, e.g. resting, sitting, walking and/or running.
  • This aspect of the invention is also particularly important since it is recognized that older men are suffering from various disabilities such as a poor eye sight that can add to the problem of applying some incontinence guards in a correct manner.
  • a male incontinence guard can be manufactured that provides the user with two different user configurations in one product. Hence, it is possible to meet two different consumer needs by one and the same male incontinence guard. The user is therefore not required to buy two different guards, having different user configurations, to assure that he has a freedom of choice in his life.
  • the first side protection portion is delimited by the first side edge, which is a portion of the first transverse edge, a portion of the longitudinal edge, and a first fold line.
  • the second side protection portion is delimited by the second side edge, which is a portion of the first transverse edge, a portion of the second longitudinal edge, and a second fold line.

  • the second fold line is created upon folding the second side protection portion over the liquid receiving surface of the guard towards and/or over the longitudinal centre line 40.
  • breakable join refers to a connection between two elements such that the elements tend to remain connected absent a separation force applied to one or both of the elements, and the elements being capable of intentional separation without substantial permanent deformation or rupture. The required separation force is typically beyond that encountered while wearing the guard in a pair of underwear during normal use.

  • the breakable joins 121 , 122 are broken when the guard is in the second configuration 108. "Breaking" in this context means to separate one element from another element at a breakable join.
  • the first configuration 104 When the guard 100 is in the first configuration 104, a configuration is formed that provides the wearer with side protection such that urine discharged from the wearer is prevented from leaking out from the guard.
  • the first configuration 104 provides a splash guard functioning in more than one direction; sideward by the side protection portions 150, 160, downward by the joint between the side edges 180, 190 to the central portion edge 185 and towards the abdomen of the user by the central portion 170.
  • the first configuration 104 enables the penis of the wearer to stay in place when the guard 100 is being used.
  • the first configuration 104 is therefore particularly beneficial when the wearer is active, e.g. walking or running, and wishes to have a good protection against urine leakage.
  • the first longitudinal edge 1 1 1 and the second longitudinal edge 1 12 are not joined to each other. Instead, the first configuration 104 is formed only by joining at least a portion of the first side edge 180 and a portion of the second side edge 190 to at least a portion of the central portion edge 170. Hence, a first configuration 104 of the guard 100 is formed that does not fully encompass the penis of the wearer. This guard is more comfortable than conventional pocket-shaped guards which may become too warm since pocket-shaped guards fully encompass the penis of the guard.
  • the side protection portions 150 160 can comprise absorbent material in form of the absorbent core 107, the first configuration 104 is beneficial when the user wishes to have absorbency capacity partly surrounding the penis.
  • the penis of the user is intended to be placed on the liquid receiving surface 105 of the central portion 170 such that the liquid receiving surfaces of the first side protection portion 150, the second side protection portion 160 and the central portion 170 partly enclose at least a part of the penis.
  • the second region 130 is intended to be located forward on the wearer.
  • the first region 1 10 is then intended to be located rearward on the wearer when the guard is being worn.
  • the second configuration 108 forms a guard that has a substantially flat shape if no elastic members 123, 124 are attached, or, as schematically illustrated in Figure 1 a, a basin-like shape if elastic members 123, 124 are attached in the longitudinal edges 1 1 1 , 1 12 of the guard 100.
  • the second configuration 108 enables the guard 100 to fit comfortably in the groin region and enclose the genitals of the male user.
  • the first region 1 10 is intended to be located forward on the wearer.
  • the second region 130 is then intended to be located rearward on the wearer when the guard is being worn.
  • the shape of the second configuration 108 allows the guard to fit comfortably in the groin region of a male wearer.
  • the guard 100 has a tapered shape as illustrated in Figure 1 a, i.e. a shape which is wider at the front of the guard and tapers towards the second transverse edge 1 17 of the guard 100 so as to allow the guard 100 to fit comfortably in the groin region of a male user.
  • the second configuration 108 is particularly useful for a wearer that prioritizes the aspect of comfort, i.e. to avoid a tight enclosing by surrounding layers.
  • This configuration provides room for the penis to be positioned in various directions and to have it freely movable in relation to the guard 100.
  • the second configuration 108 can be useful for men only suffering from minor urine leakages, i.e. drip incontinence, which may not feel a need for any supporting side protection portions.
  • the second configuration 108 may also be practical for men having reduced mobility in their hands, which is particularly common among older men. For this category of wearers it may be convenient for the wearer to be able to simply position his penis on a flat- open surface, without any need of manual dexterity.
  • a guard 100 that has the first configuration 104, and wherein the breakable joins 121 , 122 are broken when the guard 100 is in the second configuration 108 is useful. That is, the guard 100 is converted form the first configuration 104 into the second configuration 108. In this way a guard 100 is provided that can assume more than one form which allows the male wearer a freedom of choice. A user can therefore readily adapt the guard 100 according to his/her wishes.
  • the guard 100 provides a greater range of fit, allowing the same product to be used under different physical activities, e.g. resting, sitting, walking and/or running. For instance, a user may desire to have his penis to stay in place during use of the guard or to have it freely located on the guard.
  • This aspect of the invention is also particular important since it is recognized that older men are suffering from various disabilities such as a poor eye sight that can add to the problem of applying some incontinence guards in a correct manner. For instance, when it is dim light, a male user may need a guard that is easy to apply and/or use, while, when it is daylight, the same user desires to use a guard that gives an excellent protection against leakages, but which is more challenging to apply.
  • a male incontinence guard can be manufactured that provides the user with two different user configurations in one product. Hence, it is possible to meet two different consumer needs by one and the same male incontinence guard. The user is therefore not required to buy two different guards, having different user configurations, to assure that he has a freedom of choice in his life.
  • the male incontinence guard 100 can be packaged in its first configuration 104 and can then be readily converted into the second configuration 108.
  • the first configuration 104 requires less space than the second configuration 108 in the transverse x and longitudinal y direction. This is due to the fact that the side edges 180 190 of the side protection portions 150, 160 are joined to the central portion edge 185 of the central portion 170. Thereby, it is possible to relieve the user from the otherwise awkward feeling experienced when exposing a bulky and voluminous product.
  • This aspect of the invention also allows the guard 100 to be discretely transported.
  • the male incontinence guard 100 can be packaged individually, or in a multi- pack module, such as a bag or a box, comprising several individual guards.
  • a multi-pack module may contain individually wrapped guards.
  • the guard 100 comprises a longitudinal breakable join 126 in addition to the breakable join 121 , 122 at the first end.
  • the longitudinal breakable join 126 has the same characteristics as the breakable joins 121 , 122 described above.
  • the longitudinal breakable join 126 joins at least a portion of the first longitudinal edge 1 1 1 to at least a portion of the second longitudinal edge 1 12. In this manner, the first region 1 10 assumes a pocket-like shape such that when the penis is inserted into the pocket, the penis is completely surrounded by the liquid receiving surface 105.
  • the pocket is formed by joining at least a portion of the first side edge 180 and a portion of the second side edge 190 to at least a portion of the central portion edge 170, and by further joining at least a portion of the first longitudinal edge 1 1 1 to at least a portion of the second longitudinal edge 1 12.
  • This aspect of the invention gives an improved leakage protection.
  • the side protection portions 150, 160 can comprise absorbent material in form of the absorbent core 107, this aspect of the invention is beneficial when the user wishes to have absorbency capacity to completely surrounding at least a part of the penis.
