Description

Technical Field

[0001] The present invention relates to disposable laminated bedding covers.

Background Art

[0002] Conventionally, bedding covers and stretchers used in various facilities such as hospitals, hotels, and welfare facilities are likely to have sweat, dirt, blood, etc. adhere to them. Also, the sheets on the beds are likely to have sweat, urine, dirt, blood, etc. adhere to them. Therefore, in order to maintain a hygienic environment, it is necessary to frequently replace them. General bedding covers and sheets are made of cloth and can be repeatedly used by removing them and washing them after use. However, this method requires time and labor for hygiene management, and further costs are incurred for washing.

[0003] On the other hand, disposable bedding covers have the advantage that they can be discarded after only one use, thus saving the trouble of washing. However, even in disposable bedding covers, hygienic, economic, and efficient improvements are required.

[0004] As disposable bedding covers, for example, as a pillow for blood collection, an antibacterial sheet laminate for a blood collection pillow in which a sheet with a releasable adhesive applied in a strip shape on one end of one side of the sheet is laminated so that the portion where the releasable adhesive is applied is located at the same end (see Patent Document 1) is disclosed. Also, a disposable pillow cover in which a liquid-absorbent sheet is sandwiched and laminated between a liquid-permeable front-side sheet and a liquid-permeable back-side sheet (see Patent Document 2) is disclosed. Further, as a disposable sheet, for example, a plurality of sheets are laminated, and an outer peripheral sewing portion in which the plurality of laminated sheets are sewn and fixed along the long-side portion and the short-side portion of the outer peripheral portion of the sheet, and an inner peripheral sewing portion in which the plurality of laminated sheets are sewn and fixed at a position inside the outer peripheral sewing portion at a certain distance from the outer peripheral sewing portion are provided, and a disposable laminated bed sheet is disclosed (see Patent Document 3).

Mode for Carrying Out the Invention

[0011] Subsequently, with reference to the attached drawings, embodiments embodying the present invention will be described to facilitate understanding of the present invention. In the drawings, parts not related to the description may be omitted from illustration.

[0012] The following embodiments are examples for explaining the present invention and are not intended to limit the present invention to the following contents. The present invention can be appropriately modified and implemented within the scope of its gist.

[0013] The disposable laminated bedding cover 1 according to the embodiment of the present disclosure (hereinafter also referred to as "the present disposable laminated bedding cover") has a holding part 20 for holding the bedding cover body on the upper surface of the bedding bonded to the back surface of the bedding cover body 10, as shown in FIGS. 1 and 2. As shown in FIGS. 2 and 3, the bedding cover body 10 has a plurality of water-absorbing layers 31 capable of absorbing moisture and bedding sheets 33 with a waterproof film 32 adhered to the back surface of the water-absorbing layer 31 laminated vertically, and a part of the periphery of each laminated bedding sheet 33 is joined to each other. Further, a holding part 20 for holding the bedding cover body 10 on the upper surface of the bedding is bonded to the back surface of the bedding cover body 10. By peeling off the top bedding sheet 33, the top bedding sheet 33 is peeled off from the bedding cover body 10. The holding part 20 is provided with fasteners 44 to 47 used when holding the bedding so as to wrap it.

[0014] Hereinafter, each member and the like will be described.

[0015] ■Mattress Cover Body The mattress cover body 10 has a plurality of mattress sheets 33 stacked one above the other, and a part of the periphery of each of the stacked mattress sheets 33 is joined to each other.

[0016] A plurality of mattress sheets 33 are stacked one above the other. The plurality of sheets may be two or more, for example, 3 to 30 sheets, 5 to 20 sheets, 8 to 15 sheets, 10 to 14 sheets.

[0017] The above-mentioned bedding means equipment used when a user lies down in hospitals and welfare facilities such as pillows, beds, stretchers, examination tables, etc.

[0018] The shape of the mattress sheet 33 is rectangular in FIG. 1 but is not particularly limited. For example, it is a quadrilateral such as a substantially rectangular or square shape, or a circular shape such as a round, oval, or oblong shape.

[0019] A waterproof film 32 is adhered to the back surface of a water-absorbing layer 31 capable of absorbing moisture on the mattress sheet 33. For example, the mattress sheet 33 is composed of two layers, with the water-absorbing layer 31 on the front side (upper side) that contacts the head of a user such as a hospital patient or a caregiver in a welfare facility, and the waterproof film 32 adhered to the back surface of the water-absorbing layer. By providing the above-mentioned water-absorbing layer 31, it is possible to adsorb liquids such as the sweat, blood, saliva, etc. of the user of the disposable laminated mattress cover 1 and the dirt of the liquid spilled on the mattress sheet onto the water-absorbing layer 31 of the topmost mattress sheet, and at the same time, it is possible to enhance the user's feeling of use. Also, by providing the above-mentioned waterproof film 32, it is possible to suppress the penetration of the sweat, blood, saliva of the user of the disposable laminated mattress cover 1 and the liquid spilled on the mattress sheet from the topmost mattress sheet to the lower mattress sheet. Furthermore, in the state where the mattress sheets 33 are laminated, the waterproof film of the upper mattress sheet and the water-absorbing layer 31 of the lower mattress sheet contact each other, and it becomes difficult for them to adsorb even if they come into contact with each other, and it becomes easy to pick up only one sheet by hand when peeling off the topmost mattress sheet.

[0020] The material constituting the water-absorbing layer 31 in the bedding sheet 33 is, for example, rayon, paper such as crepe-processed crepe paper, plant fibers such as cotton, wool, and linen, urethane-based, polyester-based, polyphenol-based, or polyamide-based elastomer fibers, or water-absorbing nonwoven fabric. The material constituting the waterproof film 32 in the bedding sheet is, for example, waterproof resin such as waterproof polyethylene, polyester, or polypropylene, or a material that has been waterproofed by coating other materials with waterproof resin such as waterproof polyethylene, polyester, or polypropylene. The waterproof film 32 may also be made of an elastic material, and by having elasticity, for example, if the bedding sheet 33 is joined by stitching, the waterproof film 32 will not tear near the stitching and the bedding sheet 33 will be easier to peel off. The elongation rate of the waterproof film 32 is, for example, 5-30% or 10-20%.

[0021] The thickness of the water-absorbing layer 31 is, for example, 0.01 to 1 mm, 0.05 to 0.8 mm, or 0.1 to 0.5 mm. The thickness of the waterproof film 32 is, for example, 0.01 to 0.5 mm, 0.05 to 0.3 mm, or 0.1 to 0.2 mm.

[0022] For example, the weight of the bedding sheet 33 is 15-25 g / cm². 2 , 18-22 g / cm³ 2 That is the case.

[0023] The size of the bedding sheet 33 can be adjusted as appropriate depending on the size of the bedding to be fitted. For example, if the bedding is a pillow and is rectangular in shape, the width can be 28-38 cm or 31-33 cm, and the length can be 35-60 cm or 41-53 cm. If the bedding is a bed and is rectangular in shape, the width can be 80-110 cm or 83-100 cm, and the length can be 180-210 cm or 195-200 cm. If the bedding is a stretcher or examination table and is rectangular in shape, the width can be 500-800 cm or 550-700 cm, and the length can be 1600-2000 cm or 1700-1900 cm.

[0024] Each stacked bedding sheet 33 may differ in shape and size, but it is preferable that they be the same. In addition, each bedding sheet 33 may be colored, either entirely or in a part of its edge, and the color may be different from that of adjacent bedding sheets. This coloring makes it easier to confirm that a bedding sheet has been removed. Instead of coloring, a tag may be attached, and changing the position of the tag will also make it easier to confirm that a bedding sheet 33 has been removed.

[0025] Each of the stacked bedding sheets 33 is joined to one another at a portion of its periphery. The bedding sheets 33 can be joined to each other by, for example, sewing, gluing, or compression.

[0026] The parts of the periphery of the bedding sheet 33 to be joined include, for example, the long side, the short side, or a part of the outer edge. In Figure 1, the bedding sheet 33 is rectangular, and it is joined by sewing along the longitudinal direction with sewing thread at a position 1 cm inward from the edge of its long side.

[0027] Furthermore, as shown in Figure 1, it is preferable that the sutured portion of the rectangular bedding sheet 33 does not reach either end (short side) or one of the ends of the bedding sheet 33. Specifically, for example, it is possible to leave an uncut area of ​​1 to 3 cm along the short side without sutures. Such sutures make it possible to easily peel off the top layer of bedding sheet 33 with one hand.

[0028] Furthermore, as shown in Figure 4, in the case of a rectangular bedding sheet 33, if it is sewn to the edge, the inner uppermost layer of the bedding sheet 101a peels off from the sewn area (Figure 4, bottom right), exposing the inner second-to-top layer of the bedding sheet 101b, while the outer uppermost layer 102a remains attached to the bedding sheet body (Figure 4, bottom left). On the other hand, as shown in Figure 5A, if the sewn area does not reach either end (short side) or one of the ends of the bedding sheet 33, both the inner uppermost layer of the bedding sheet 101a and the outer uppermost layer 102a peel off from the sewn area (Figure 5, bottom right), exposing both the inner second-to-top layer of the bedding sheet 101b and the outer second-to-top layer 102b (Figure 5A, bottom left).

[0029] As shown in Figure 5B, the sheet in the lower right of Figure 5A can be made into a string-like shape by tearing one end of the sutured area, which forms the area 102a outside the sutured area. Therefore, by folding and tying the entire uppermost layer of the bedding sheet 33 that was torn with this string-like uppermost layer 102a outside the sutured area, it is possible to make the discarded bedding sheet 33 more compact.

[0030] Furthermore, it is preferable, from the viewpoint of easily peeling off the bedding sheets, that a portion of the periphery of each stacked bedding sheet 33 is joined along the vertical grain direction of the bedding sheet 33.

[0031] ■Holding part The retaining portion 20 is joined to the back surface of the bedding cover body 10, that is, to the back surface of the bottom layer of bedding sheet 33. The joining method can be, for example, sewing, gluing, or pressing. If the bedding cover body 10 is rectangular, for example, the retaining portion 20 is joined to the back surface of the bedding cover body 10 at both ends of the long or short sides of the bedding cover body 10. By joining the retaining portion 20 to the back surface of the bedding cover body 10 at both ends of the long or short sides of the bedding cover body 10, the joined area becomes easier to tear when peeling off the bedding sheet. The joining points of the laminated bedding sheets 33 and the joining points of the retaining portion 20 and the back surface of the bedding cover body 10 do not necessarily have to overlap, but overlapping them simplifies the manufacturing process.

[0032] The holding part 20 can be any shape that can hold the bedding cover body on top of the bedding to be covered, for example, it can be a sheet shape, a band shape, or a string shape. From the viewpoint of preventing soiling of the bedding, a sheet shape is preferable as shown in Figure 1.

[0033] The material constituting the holding part 20 is, for example, a waterproof resin such as waterproof polyethylene, polyester, or polypropylene, or a material that has been waterproofed by coating other materials with a waterproof resin such as waterproof polyethylene, polyester, or polypropylene. Sweat, blood, saliva, and liquids spilled on the bedding sheet by the user will not penetrate to the bottom layer of the bedding sheet 33 due to the waterproof film of the bedding sheet 33. However, the bedding may become soiled by sweat, blood, saliva, and liquids spilled on the bedding sheet from areas not covered by the bedding sheet 33. Therefore, by using a waterproof material in the holding part, it is possible to prevent soiling of the bedding by sweat, blood, saliva, and liquids spilled on the bedding sheet from areas not covered by the bedding sheet 33.

[0034] For example, the weight of the holding part should be 15-25 g / cm³. 2 , 18-22 g / cm³ 2 That is the case.

[0035] Figure 6 shows only the holding portion 20, with a pattern added to indicate the area. As shown in Figure 6, it comprises, for example, a bedding cover body connecting region 41 that connects to the bedding cover body 10, and a short-side holding region 42 that extends outward from the right and / or left side of the bedding cover body 10. Furthermore, it may also comprise a bedding cover body connecting region 41 that connects to the bedding cover body 10, and a long-side holding region 43 that extends outward from the top and / or bottom of the bedding cover body 10. The short-side holding region 42 and the long-side holding region 43 cover the bedding, making it possible to house the bedding inside the disposable laminated bedding cover. The short-side holding region 42 and the long-side holding region 43 are fitted with fasteners 44-47, and the holding portion 20 covers the bedding, fixing the bedding cover body to the top surface of the bedding. Examples of fasteners include hook-and-loop fasteners, zippers, buttons, hooks, and magnets.

[0036] For example, when using hook-and-loop fasteners as fasteners, fasteners 44 and 45 are attached to the surface of the holding part (the side to which the bedding cover body is attached) with the hook-and-loop fastener (hook side), and fasteners 46 and 47 are attached to the back of the holding part (the side opposite to the side to which the bedding cover body is attached) with the hook-and-loop fastener (loop side). When wrapping the bedding, fasteners 44 and 46 can be connected by folding fastener 46 over fastener 44, and fasteners 45 and 47 can be connected by folding fastener 47 over fastener 45.

[0037] ■ How to use disposable layered bedding covers The instructions for using the disposable layered bedding cover 1 will be explained using a pillow as an example. Spread the disposable layered bedding cover 1 on a horizontal surface with the back side facing up and the top layer of the bedding cover body 10 facing down. Place the pillow on top of the disposable layered bedding cover 1 so that the pillow and the bedding cover body 10 are aligned.

[0038] The short-side holding areas 42 on both sides are folded to cover and enclose the pillow, and the fasteners 44 and 46 are connected and secured. Similarly, the long-side holding areas 43 on the long sides are folded to cover and enclose the pillow, and the fasteners 45 and 47 are connected and secured. With the pillow wrapped and held in this state, it is turned upside down and placed so that the top layer of the bedding cover body 10 is on top. The user's head is placed on the surface of the top layer of the bedding sheet 33 of the bedding cover body 10.

[0039] Once a user has finished using the pillow, the person changing the bedding cover can peel off the top layer of bedding sheet 33 by hand from the edge, rather than the entire disposable layered bedding cover 1, thus removing and discarding one sheet at a time. The second layer of bedding sheet 33 then becomes the top layer (outermost layer), which the next user can use as is. By repeating this process, for example, if there are 12 layers of bedding sheets, one bedding cover can be used for 12 users. Therefore, it is possible to reduce the workload for staff at facilities such as hospitals and welfare facilities, who previously had to remove each bedding cover and attach a new one, and to reduce laundry costs at the aforementioned facilities.

[0040] Furthermore, if a bedding cover is used in which the short edge is not sewn for 1 cm and an uncut area of ​​1 cm along the short edge is left, the edges remain connected, and although a cut will be made in the sewn area, it becomes possible to peel off the entire top layer bedding sheet 33. Therefore, it becomes a disposable laminated bedding cover that is more hygienic.

[0041] This disposable layered bedding cover 1 can be used in facilities such as hospitals, welfare facilities, rehabilitation facilities, and barber shops for use as pillows, beds, and stretchers when users lie down. [Explanation of Symbols]
