PAPER NAPKIN

Abstract: The invention relates to a paper napkin or similar sheet formed object which is intended to be attached to an article of clothing to protect it from spillage. This has been achieved before with the use of adhesive surfaces at the upper part of the napkin, which surfaces before usage are protected by peel off paper labels. It is for several reasons impractical to use loose paper labels for this purpose. According to the invention the napkin is instead folded before usage so that the adhesive surfaces (3) are in close contact with a part of the napkin, which in this position forms a protection for the adhesive surfaces (3).

Description: PAPER NAPKIN The present invention relates to a paper-napkin of the type, stated in the introduction of the following claim 1. Paper-napkins are priorly known, which are provided with at least one such limited surface coated with an adhesive layer, which before usage is protected by a removable paper slip or peel off label. Such a paper slip will roost likely end up on the floor, and if this type of napkin is used by many in a room it will be very littered with all the paper slips on the floor. If the napkin is provided with two such limited surfaces with a protective paper slip each, there will be not only twice as littered but also more complicated to handle the napkin while removing the paper slips with change of grip and with the risk that the adhesive surfaces will stick somewhere in an uncontrollable way. The object of the invention is to bring about a napkin, where these inconveniences are eliminated. This has according to the invention been achieved by that, the napkin has obtained the characteristics stated in claim 1. By the invention the use of loose paper slips or peel off labels as protection for the adhesive surfaces has been made unnecessary. Also the handling of the napkin has been made easier. If the napkin has been provided with adhesive layers in at least two corners of the unfolded napkin the unfolding of the napkin is made at the same time as the corners are drawn apart, and without changing the grip, the corners of the napkin can be pressed on the intended article of clothing, for example a shirt or a blouse. The paper-napkin is often made of a liquid-absorbing material with very poor mechanical strength properties. Thus, according to a preferred embodime of the invention, the napkin suitably is designed in accordance with the characteristics of claim 3. The invention is more closely clarified with reference to the accompanying drawing which on figures 1-7 schematically shows different embodiments of napkins according to the invention. Fig. 1 shows a part of a napkin with a reinforcement area 1 along an edge portion of the napkin. the reinforcement area has non-adhesive parts 2 and limited adhesive parts 3. The reinforcement area 1 can be achiev in many ways, for example with pressure, heat treatment and/or chemical treatment of a sheet 4 of a web of material with appropriate properties. The sheet 4 can alternatively be provided with a reinforcement area in the shape of a strip of tear-resistent paper or plastic. Farthest out the reinforcement area is non-adhesive to form grip surfaces 5, and one grip surface 5 is arranged to stick out outside the edge of the napkin a short distance to form a pull flap 6. The adhesive surfaces 3 are positioned so, that when folding the napkin along a folding line 7 the adhesive surfaces 3 on one half portion of the reinforcement area will be positioned on the non-adhesive surfaces 2 on the other half portion and reverse. By that it will be easier to draw apart the halves than if the adhesive surfaces 3 on the two halves would be positioned opposite each other, and in this case the reinforcement area 1 can possibly be spared and the adhesive surface 3 be arranged directly on the sheet 4. Fig. 2 shows an alternative design with the adhesive surfaces 3 vertically displaced. Fig. 3 shows a design with the reinforcement areas 1 positioned in the both upper corner parts of the napkin and sticking out unequally long laterally to form grip surfaces 5 and at the same time pull flaps 6, with the adhesive surfaces 3 extending to the grip surfaces 5. With a design according to Fig. 4 which is similar to the one in Fig. 3, the adhesive surfaces 3 are vertically reduced to half the height and mutually, vertically displaced. Fig. 5 shows a design similar to the one according to Fig. ' 3, but instead of having the reinforcement areas 1 arranged with pull flaps 6, non-adhesive surfaces are arranged furthest out in the corners serving as grip surfaces 5. Fig. 6 shows a modified design of the one shown in Fig. 5. Fig. 1-6 show designs where the adhesive surfaces 3 are positioned on the front side of the sheet 4 shown on the drawing. These must be affixed before the sheets 4 are folded up along the line 7. A simpler manufacturing can be obtained if the sheets 4 first can be folded along the line 7 and after that be equipped with reinforcement strips 1 on the outsides who are provided with, vertically and/or laterally protruding, adhesive surfaces 3. Such a design is shown unfolded in Fig. 7. The entire surface of each reinforcement strip 1 is provided with an adhesive layer, the lower parts to stick to the back of the sheet 4 and the upper parts to stick to each other when the halves of the sheet are folded together. The adhesive surfaces 3 can, of course, as shown earlier, be mutually displaced, so that the adhesive surfaces easier can be drawn apart with the lower parts forming very good grip surfaces 5. The adhesives used are of the kind, that do not become inactive but remain permanently active, and the adhesive capacity is adjusted depending on the strength properties of the napkins. An example of usable adhesives is the kind used for note pads of the type called Post-it (reg. trademark) . For stronger adhesive capacity the adhesive used for self-adhesive tape can be used, however not so that the adhesive surfaces will be in contact with each other, since the adhesiveness in that case might be too strong.
