Description

FIELD OF TECHNOLOGY

The present invention relates to a disposable type lining for protecting objects in need of protection, for example, seat cushions, bedding or changing tables. The lining consists of a moisture-absorbing coating layer that is placed outside of the object to be protected, and a substantially moisture-proof back layer adjacent to the object to be protected during use. The lining also includes means for closing the lining after use.

BACKGROUND

In hospitals and other medical institutions, as well as in the field of home care, various types of disposable linings are used, for example, to protect chairs and beds, to prevent the penetration of urine and / or feces, and to contaminate bedding and mattresses in beds and seat cushions in chairs . Typically, in cases of changing diapers in infants, linings are used, for example, to protect the changing table on which the diaper change is performed. When the lining of this type has become contaminated with urine and / or feces, the usual procedure for the lining is that it is folded or folded so that the waterproof back layer is on the outside, so that the contents of the protective device are well insulated from the external environment. Such handling of the lining facilitates its subsequent processing and eliminates the problem of unpleasant odors when the lining needs to be discarded.

A situation also arises in which the used diaper is placed in the lining, after which the lining is rolled up around the diaper so as to form a hygiene bag convenient for disposal.

One type of lining intended for changing tables is described in JP 2002248126 A. The lining includes an adhesive surface arranged on a back layer adjacent to one of the edges of the guard, where the adhesive surface is designed to close the lining after use and folding. The document also provides that the diaper may be placed in a protective device before it is folded and disposed of.

One disadvantage of the protective device with the adhesive surface directly on the backing layer is that the adhesive surface is facing outward from the collapsed protective device when the latter is folded / rolled up with the backing layer facing outward, which is the best and most common method of folding. The portion of the lining that contains the adhesive surface must accordingly be folded again so that the adhesive surface abuts the backing layer of the lining so that the lining can be closed.

The connection between the backing layer and the adhesive surface due to the aforementioned folding will also be loaded in an unfavorable manner and will be subjected to a breaking force, which significantly reduces the strength of the joint compared to a situation in which the joint is instead subjected to a shear force.

A further disadvantage of an adhesive surface arranged as described in JP 2002248126 A is that the adhesive surface must be coated with some form of protective layer before the adhesive surface is used and subsequently the protective layer must be removed before use. A separate protective layer, therefore, requires additional processing in connection with the disposal of the lining, which can cause certain problems.

Other documents describe various types of linings, including means for securing the liner to the bed, for example, when using the liner. U.S. Pat. No. 4,097,943, for example, describes a bed liner that contains adhesive threads along the edges to attach it to bedding.

In principle, the same problem is encountered with the type of protective device described in JP 2002248126 A.

EP 0.218.568 describes linings provided with special surfaces including materials with a high coefficient of friction, in which the purpose of using surfaces with a high coefficient of friction is to make the lining lie still in the bed, even if the patient is in bed. The function of the protective devices of this type essentially does not take into account the closing of the protective device in a folded configuration, which is suitable for disposal after use.

Thus, there is a need for a lining that can be folded and closed in a simple and hygienic manner after the lining has been folded or rolled up in connection with its disposal.

DESCRIPTION OF THE PRESENT INVENTION

However, the lining of the kind mentioned in the introduction has become available thanks to the present invention, which essentially overcomes the problems that were associated with earlier already known products.

The lining in accordance with the present invention is noted primarily in that the means for closing the lining after use include at least one locking flap comprising a first end region and a second end region. The first end region is permanently attached to the backing layer or to the liquid-absorbing coating layer, and the second end region of the locking flap includes a locking device for attaching to the lining after use.

By providing the lining with a locking flap, in which one end is permanently attached to the lining and the other end is free and includes a locking device, the locking flap is an effective closing device for the lining after it has been used and possibly contains urine.

In accordance with one embodiment, the lining includes an absorbent layer interposed between the moisture-absorbing coating layer and the backing layer. By providing the lining with a separate absorbent layer, which is separated from the moisture-absorbing layer, very large amounts of the substance excreted from the body can be absorbed without using the lining, which must be unreasonably expensive to manufacture.

In accordance with one embodiment of the lining, the latching device is located on that side of the latching flap that faces the lining. The locking flap can be closed by placing the locking device on the lining without wrapping the locking flap in the longitudinal direction.

In accordance with one embodiment of the invention, the second end region of the locking flap is removably attached to the revolving layer or to the coating layer absorbing the liquid. The temporarily attached end region of the fixing flap is protected by the indicated embodiment from being released from the surface of the lining, which could have occurred when using the lining.

In accordance with one embodiment, the locking device includes an adhesive surface. Since, of course, most linings have a backing layer made of a plastic film to which the adhesive material can be adhered perfectly, a fixing device including adhesive material offers an inexpensive and efficiently functioning solution.

According to one embodiment, a protective layer is disposed between the protective device and the backing layer or the moisture absorbing coating layer. The protective layer is treated with a release agent on the side that faces the protective device, the opposite side of the protective layer being permanently attached to the backing layer or to the moisture-absorbing coating layer.

According to another embodiment, the revolving layer or the moisture-absorbing coating layer is treated with a release agent at the place where the fixing device is removably attached to the revolving layer or the moisture-absorbing coating layer. The specified embodiment provides material savings and an inexpensive solution for the fixing flap, which is removably attached to the lining, although this imposes certain synchronization requirements in connection with the production of the lining.

One embodiment is characterized in that the fixing device comprises a Velcro® element of a male type or female type designed to interact with at least one Velcro® element located on the backing layer or on the moisture absorbing coating layer. The advantage of using Velcro® elements on the fixing device and on the lining is that the closing means are effective even if the surface where the closing is carried out is wet or dirty, for example, skin ointment or the like.

In one embodiment, the backing layer or the moisture-absorbing coating layer of the lining includes at least one surface that can interact with a Velcro® element located on the fixing device.

One embodiment is characterized in that the backing layer of the lining includes a non-woven material located at a distance from the moisture-absorbing coating layer of the lining, and the non-woven material can interact with the Velcro® element of the fixing device. A non-woven fabric including ears of a suitable type is a very economical material that is capable of interacting with a covered type Velcro® element.

According to one embodiment, the means for closing the linings are located on the back layer of the liner. The use of closing means located on the back layer of the lining means that the means do not affect the use of the lining, for example, as a protective device for a bed or changing table. The use, in addition, means that it is especially convenient to use these means after the lining has been folded / rolled with a substantially waterproof layer facing outward, because the tool automatically ends on the outside in connection with the specified folding / rolling.

According to one embodiment, the locking flap consists of a paper strip, the paper strip including a folded region, so that the locking flap can be extended by stretching the folded region. Paper is an inexpensive and efficiently functioning material for a latch flap, which is suitable as a lining closure device.

According to another embodiment, the locking flap includes an elastic region, wherein the locking flap can be extended by stretching the elastic region.

In accordance with one embodiment, the second end region of the latch flap is located between the first end region of the latch flap and the lining edge when the latch flap is in its primary folded or unstretched state. When the folded section is deployed or when the elastic region is stretched, the second end region of the locking flap extends beyond the edge of the lining. The indicated embodiment allows closing the used and folded / folded lining near the edge of the lining. The location of the locking flap near the edge of the lining is comparable to the commonly encountered method of folding / rolling the lining after use.

DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS OF THE PRESENT INVENTION

The present invention relates to a disposable liner, including a mechanism for closing the liner in a folded form, which is suitable for disposal after use.

The linings of the type described here have many different applications for caring for patients in a hospital, home care and infant care using persons without special training.

The linings are primarily used to protect bedding and mattresses in connection with the care of patients with incontinence, although the protection of seat cushions, wheelchairs, etc. is also common. Changing tables, on which diapers are changed on babies, are another surface that is customarily protected with various types of linings.

The Figure 1 shows the main components of the lining 101 in accordance with the invention.

The lining 101 is almost rectangular and has four edges 112, 113, 114, 115.

The liner 101 includes a moisture-absorbing coating layer 102 located on the surface of the liner 101, which is designed to adhere to the user during use. The lining 101 further has a backing layer 104 located on the surface of the lining, which during use is intended to lie against the object that the lining should protect. The liner also includes a separate absorbent mass 106 located between the moisture-absorbing coating layer 102 and the backing layer 104. Since the liner 101 includes a separate absorbent mass 106, the primary function of the moisture-absorbing coating layer 102 is to allow liquid to pass through it, thereby absorbing the moisture-absorbing coating. layer 102 is irrelevant or only of secondary importance.

The moisture absorbing coating layer 102 of the lining 101 is located outside the absorbent mass 106 over the entire periphery of the absorbing mass 106. The moisture absorbing coating layer 102 may consist of any material that is suitable for this purpose. Examples of commonly used moisture-absorbing coating materials are non-woven textile materials, known as non-woven materials, perforated plastic films, nets made of plastic or fabric, and permeable foam layers. Moisture-absorbing coating materials made from thin continuous fibers that extend throughout the lining are also acceptable. Multilayer products consisting of two or more of the aforementioned possible coating materials are also often found in the form of coatings consisting of various materials in different parts of the surface.

The pads 101, including the absorbent mass 106, which exhibit particularly high efficiency and wear resistance, can even function without the need for any additional moisture-absorbing coating layer on the side of the pad 101, which is adjacent to the wearer during use.

Some alternative linings do not have any special absorbent mass, but the moisture-absorbing coating layer consists of a combined coating and absorption layer. A common feature of such layers of materials is that they contain natural fibers, such as cotton fibers, or viscose fibers. Lining, which is made without a separate absorption mass, is intended primarily for situations in which large quantities of absorbed liquid are not expected.

The backing layer 104 also extends outside the absorbent mass 106 around the entire periphery of the absorbing mass 106. The backing layers 104, which are usually present in the linings 101, are usually waterproof, although other types of backing layer may also be provided. The backing layer 104 may consist of a number of different materials. Typically, the backing layer 104 may consist of a thin, liquid-impermeable plastic film, although it is also possible to use other types of liquid-impermeable materials, for example non-woven materials that have been made liquid-impermeable, for example by means of a plastic coating, liquid-impermeable foam layers, liquid tight adhesive material or the like. The backing layer 104 may also consist of a waterproof vapor-permeable material, as a result of which the lining 101 has a certain ability to "breathe", which makes the lining more convenient to use. Also found are multilayer products containing at least one liquid-impermeable layer, usually located on the absorbent mass 106. These multilayer products usually consist of a liquid-impermeable material that acts as a moisture barrier, as well as fabric-like material located on the lining side 101, which is adjacent to the object to be protected. Pads that have such a backing layer exhibit more friction with an object that needs to be protected, for example, compared to a backing with a polymer backing, thereby reducing the tendency to shift from the starting position during use. A fabric-like layer of a multilayer material usually consists of a non-woven layer, although it naturally can also consist of other textile materials.

To ensure that the lining remains in place without sliding over the supporting surface (the object to be protected), there are also lining with adhesive surfaces and / or high friction surfaces located on the corresponding parts of the side of the lining, which is designed to fit against object to be protected.

The moisture-absorbing coating layer 102 and the backing layer 104 are connected to each other outside the absorbent mass 106 along the entire periphery of the absorbent mass 106.

The moisture-absorbing coating layer 102 and the backing layer 104 can be attached to each other in many different ways. Examples of joining methods include bonding, heat alloy, ultrasonic welding, or the like.

The lining 101 is characterized above all and most of all by the fact that it has a device 120 for closing the lining 101 after use.

Figure 2a shows the closure 120 in cross section along line II-II of Figure 1, and therefore, the closure 120 is shown in a pre-use position.

The device 120 includes an elongated locking flap 121, a protective layer 122 and a locking device 123. The locking flap 121 is located at the edge 112 of the pad 101, whereby the flap is permanently attached to the revolving layer 104 adjacent to its first end region 124. The second end region 125 of the locking flap 121 is removably attached to the backing layer 104 of the lining 101 through a protective layer 122 that is treated with a release agent.

The protective layer 122 is treated with a release agent on a side that is adjacent to the locking flap 121, while the opposite side of the protective layer 122 is not treated with a release agent. The side of the protective layer 122, which is not treated with a release agent, is permanently attached to the backing layer 104 of the lining 101 through adhesive connections 127. The side of the protective layer 122, which is treated with a release agent, is removably attached to the locking flap 121 through the fixing device 123, while fixing the device 123 is permanently attached to the locking flap 121.

The protective layer 122 consists of a piece of paper-made material that is treated with a silicone-based release agent on the side that abuts the locking flap 121.

In alternative embodiments, the protective layer may consist of a polymer layer that reinforces the backing layer 104 of the pad 101 so that the adhesive surface of the fixing device 123 can be separated from the backing layer 104 of the pad 101 without damage by tearing off the backing layer despite the relatively high separation force. Relief polymer layers in this case are preferred, since the active surface of the adhesive joint is reduced, as a result of which the separation force is reduced.

In other alternative embodiments, it is permissible not to use a separate protective layer, but instead, the backing layer of the lining 101 is treated in some places with a release agent where it is intended, as a result of which the fixing device must be capable of separation.

The fixing device 123 preferably has an adhesive surface capable of holding most of the materials that are commonly used in the linings 101, especially the surface of the polymer film, which is the backing layer material that is commonly used in the liner.

The locking device 123 does not reach the front edge 128 of the locking flap 121, which facilitates the grip of the locking flap 121 when it is separated from the protective layer 122.

In alternative embodiments, the locking device may consist of male and female parts such as Velcro® material or the like. When using fixing devices made of Velcro® material, it is required that the back of the lining be provided with receiving surfaces consisting of male and female parts such as Velcro® material, at the place where the fixing device is to be attached, and that the protective layer includes Velcro® type material. It is also possible to provide versions in which essentially the entire back of the lining is made of material with the ability to interact with female or male components of the Velcro® type, as a result of which special receiving surfaces located on the back of the lining are not required. It is possible, for example, to provide that the backing layer of the lining include non-woven materials containing loops, as a result of which it could interact with a fixing device made of Velcro® material such as a hook.

The locking flap 121 in its initial state is Z-shaped, and therefore the leading edge 128 of the locking flap 121 is located close to the edge 112 of the pad 101, thus the second end region 125 of the locking flap 121 extends beyond the edge 112 of the pad 101. when the Z-rolled part is pulled. The locking flap 121 consists of a strip of paper, although in alternative embodiments, it may consist of a strip of non-woven material, plastic or similar materials.

Various types of multilayer materials are also allowed as fixing flaps.

At the second end region 125 of the locking flap 121, a closing device 123 is located on the side of the locking flap 121, which is adjacent to the backing layer 104 of the pad 101.

Figure 2b shows the fixture 120 in its disengaged state before closing the backing 101 on the backing layer 104. The second end region 125 of the locking flap 121, including the locking device 123, now represents the free end of the locking flap 121. Z-folding locking the flap 121 is now elongated so that the locking flap 121 extends beyond the edge 112 of the lining 101. The flap clasp 121 has not yet been secured to the lining 101. The locking device 123 is facing under masonry 101.

Figure 2c shows a cross-section of the fixture 120 of Figure 2b when the flap 121 is secured to the backing layer 104 of the pad 101 and to the part of the pad 101 to which the flap 121 is attached. The pad 101 is folded / rolled so that the backing layer 104 of the pad 101 is facing out and a flap 121 is attached thereto. The connection formed between the backing layer 104 of the pad 101 and the fixing device 123 is substantially constant because the backing layer 104 of the pad is not treated with a release agent at the point where The specified connection is found.

A sealed and hygienic product has been created that is easy to handle / dispose of, even if the product contains urine or feces.

Figure 3 shows the lining 101 of Figure 1 after it has been rolled so that the backing layer 104 is facing outward. The pad closure 120 has not yet been used.

In Figure 4, a tool 120 for closing the pad 101 was used and the locking device 123 was attached to the revolving layer 104, so that the pad 101 is fastened by the locking flap 121. An indication of the folds that result from the Z-folding of the locking flap 121 are shown in in the form of transverse stripes on the flap 121.

Figure 5a shows an alternative embodiment of the device 120 for closing the pad 101 and the portion of the pad 101 to which the device 120 is to be attached.

The flap 121 in this embodiment has an elastic region 129 between the first and second ends 124, 125, and therefore, the flap 121 can be stretched in the longitudinal direction of the flap 121. The elastic locking flap 121 can be stretched so that the second end flap area 125 extends beyond lining edge 112. The flap 121, therefore, does not have to be folded in its original configuration so that the second end region 125 of the flap 121 can be extended beyond the edge 112 of the pad 101.

The end regions 124, 125 of the locking flap 121, that is, the region where the flap 121 is attached to the backing layer 104 of the pad 101, do not have any elastic properties. One reason for this is that it is comparatively more difficult to attach the elastic material than the inelastic material to another material, although it is naturally also possible that the end regions 124, 125 of the latch flap 121 consist of an elastic material.

The end region 124 of the hinged fastener 121 is permanently attached to the backing layer of the liner 101, while the second end area 125 is removably attached to the backing layer 104. The backing layer 104 in this case is processed in some places with a release agent under the fixing device 123, as a result of which in the said embodiment no separate protective layer is required.

Figure 5b shows how the folded / folded pad 101 was closed after use in such a way that the backing layer 104 was facing outward. The waterproof backing layer 104 is an effective barrier against any substance secreted by the body contained in the lining 101. The elastic region 129 of the flap 121 was extended beyond the edge 112 of the lining before it was attached to the backing layer 104 of the lining 101. A new connection formed between the backing layer 104 and the closing device 123, in this way, can be regarded as permanent, since the backing layer is not treated with a release agent in the place where the connection is located.

The invention also includes all possible combinations of the described illustrative embodiments.

Furthermore, the present invention is not limited to the above illustrative embodiments, but is naturally applicable to other embodiments within the scope of the following claims.
