Description:
D I SPOSAB LE SAN I TARY TO I LET S EAT COV ER .

This invention relates to a disposable sanitary toilet seat cover of the type capable of being flushed in the toilet and compris¬ ing a foil or paper sheet provided with a round-going weakening line dividing the cover into a central field and an annular field , the latter serving to protect the user from contact with the toilet seat, the cover by means of a pressure adhesive being fixable in relation to the toilet seat.

Several types of covers for toilet seats are known which are intended to protect the user against the transfer of contagious matter that may be present on the toilet seat. An example of such cover is shown i . a. in DE 2, 209, 195 and DE 2, 714, 586. Such a cover has a shape and extension such as to be capable of overlying and covering a conventional toilet seat, and is usual ly intended for use once only and subsequent disposal either by flushing or by deposi¬ tion in sanitary containers . The known cover sheets or cover strips are frequently made from a relatively stiff material to facilitate the fixation of the sheet on the toilet seat. Such cover sheets or strips are as a rule disposed of by deposition in sanitary containers . Moreover, from D E 914, 181 such cover is known which provides a protective ring and which is fixed by means of an adhesive .

Alternatively, such cover sheets or cover strips such as those disclosed in US 4, 050, 105 are constructed with marginal zones adapted to be folded around the edge of the seat, or with means intended to be engaged with the toi let seat and/or the toi let bowl in one way or another to obtain fixation of the cover . Such covers are shown i . a . in NO 48, 638 and GB 2, 097, 832. The sheets disclosed in said publications either permit said engagement with the toilet seat and/or the toilet bowl or, alternatively an inner part of the sheet is total ly removed to lay open the toilet for use . Therefore, it can in many cases be a relatively cumbersome procedure to fix covers or strips which ensure a safe protection of the user, especially if this cover sheet consists of a relatively soft material suitable for being flushed in the toilet after use . i t is the object of the invention to remedy the above men¬ tioned drawbacks and to provide a cover which , when folded , can- be carried along by the user and which presents itself as a disposable

paper or foil cover, which can easily be placed on and fixed to a toi¬ let seat, and which does not only protect the user against direct contact with the toilet seat, but also gives protection against contact with the inner side of the toilet bowl , and at the same time comprises a portion that can be used as toilet paper, the cover , also being suitable for use by a cleaning staff to "seal" toilets after cleaning .

With this object in view the disposable sanitary toilet seat cover according to the invention is characterized in that the central field is provided with at least one weakening line dividing it into at least a first and a second field portion, one of which can depend into the toilet bowl , while another field portion can be used as toilet paper. Such a cover can easily be applied to and fixed to the toilet seat by the user. If the cover is used by a female user, the whole of the central field is torn off so that only the annular field remains and covers the toilet seat as such, and the opening produced .by the tearing off makes it possible to ' use the toilet. When the cover is used by a male user, only the said second field portion of the cen¬ tral field is torn off, and the said first field portion is bent into the toilet bowl , whereby it will protect the user against the transfer of contagious matter by contact with the inner side of the bowl . In both situations of use, the central field or the said second field portion may be employed as toilet paper, and after use the cover in its entirety can be flushed away.

Thus, the cover according to the invention can be conver- ted into a protective sheet, which in use gives the user an efficient protection against the transfer of contagious matter. Moreover, when the central field is not wholly or partly torn off, the cover can be used as a totally covering protective sheet. I n this state it can also be used e. g . by the cleaning staff in hotels or the like, which after cleaning applies the cover to the toilet seat and omits to remove the central field so that a subsequent user has the certainty that the toilet has not been used after cleaning .

When folded , covers according to the invention can be sold In vending machines or in packages containing a suitable number of covers for travel or the like purposes .

I n summary, it can be said that with a cover according to the present invention a combination of several provided advantages

is obtained , as the cover, which can easily be fixed to the toilet seat by means of a pressure adhesive, by means of said at least one weakening l ine provides a very hygienic product, which when used by a male user protects against both contact with the seat surface and the inner side of the toilet bowl , and when used by a female user provides the necessary protection against contact with the surface of the toilet seat, as the female user wil l be able to use the entire central field as toilet paper . The special design of the cover sheet with weakening lines in combination with the adhesive wil l furthermore render it possible to use the cover sheet to seal toilets after cleaning , which sealing offers the above mentioned advantages to the next user at the same time as the user can be sure that the toilet has not been used after the cleaning .

I n a preferred embodiment of the invention , the sheet is more easily tearable along the additional weakening l ine or l ines than along the round-going wea kening l ine . Thereby the advantage is ob¬ tained that when the user tears off the central field , this will always start with a partial tearing off of the central field , because the said first field portion , which is intended to depend into the toilet bowl , wil l remain connected with the annular field . Thereafter the first field portion can be torn off, if the cover is to be used by a female user .

I n a further embodiment, the cover advantageously may be provided with a pressure adhesive of a type not requi ring the use of a protecting strip . Hereby the appl ication and fixation of the cover becomes particularly quick and simple, because the user does not have to remove protection strips from the rear side of the cover before applying it to the toilet seat.

The invention wil l now be described in further detail with reference to the accompanying drawing , in which

Fig . 1 is a plan view of a disposable sanitary toilet seat cover according to an embodiment of the inven¬ tion , and Fig . 2 a part-section th rough a toilet bowl with seat, to which a cover according to Fig . 1 has been applied . Fig . 1 shows a disposable sanitary toilet seat cover in the

form of a mainly oval paper sheet 1 , which has an extension substan¬ tial ly matching - with the outer contour of a conventional toilet seat 2. The cover is seen from the side, which in use is applied to the toilet seat. The paper used for the cover is of a type suitable for flushing after use so that al l parts of the paper sheet can be disposed of in the toilet.

The paper sheet 1 Is provided with a weakening line 3 which divides the sheet 1 into a central field 4 and an annular field 5. Moreover, the sheet has a finger hole 6, which can be used for gripping in the process of tearing off the whole of the central field or a portion 4B thereof . A further weakening line 7 divides the central field into at least two field portions , one of which 4A can depend into the toilet bowl , while the other field portion 4B can be used as toilet paper . The annular field 5, which is intended to be applied to a toilet seat, has an extension corresponding to that of a conventional toilet seat. The annular field 5 will therefore protect the user against any contagious matter on the toilet seat. The paper sheet 1 is fixed easily and quickly- to the toilet seat by means of pressure adhesive 8 placed on the underside of the paper sheet. This pressure adhesive 8 is in the embodiment il lustrated provided In six spots , but any number of spots can be used or the pressure adhesive may be provi¬ ded in an annular zone along the whole of the annular field 5. The adhesive is of the type not requiring the use of a protective strip and not leaving adhesive residues on the toi let seat. By using such an adhesive the paper sheet 1 can be applied to the toilet seat 2 very conveniently and quickly. Such an adhesive is e. g . known from POST- I T® labels .

When the sheet is used by a female user, the whole of the central field 4 is torn off , whereas a male user wil l al low the field portion 4A to remain attached to the annular field 5 so that it pro¬ tects against contact with the Inner side of the toilet bowl . The weakening lines 3 and 7 are so arranged that the sheet can more easily be torn off along the line 3 than along the line 7. The field portion 4A wil l thus normal ly remain attached to the annular field 5 and must then be torn off separately when desired .
