Abstract

A holder, which may accommodate an insert, comprises first and second layers 16,18, and at least one closed side formed by welding 28 the first and second layers 16,18 together. At least one other side of the holder is kept open during welding by the local placing of a barrier layer between the layers 16,18, such as to provide a holder with at least one open side, into which an insert might be placed. The finished item may be such as a computer mouse mat.

Description

A HOLDER FOR AN INSERT
This invention relates to a holder for an insert, for example a sheet material insert.
Holders for sheet material inserts are known. The known holders comprise a first layer and a second layer which are stuck together along one side to form an open folder. The first layer is stuck to the second layer using double sided adhesive tape. In order to ensure that the two layers remain stuck together during use, the adhesive tape is relatively wide, for example from 30 - 40mm wide.
The use of such wide adhesive tape has the double disadvantage of first of all restricting the available inside area of the holder, and secondly of requiring printing on the top layer in order to mask the area of adhesion for cosmetic purposes. This printing represents an additional cost in the manufacture of the holder.
It is an aim of the present invention to provide a holder which is able to be produced without the need for the adhesive tape and its attendant disadvantages.
Accordingly, in one non-limiting embodiment of the present invention there is provided a holder for an insert, which holder comprises a first layer, a second layer, at least one closed side which is formed by welding the first and second layers together, and at least one open side for
enabling the holder to receive the insert, the open side being such that it has been kept open during the welding of the closed side by the positioning of a barrier sheet along the open side and between the first and second layers whereby the first and second layers are prevented from being welded together along the open side during the welding of the closed side.
The holder of the present invention can thus be produced by a new method which avoids the use of the adhesive tape. The holder produced by the new method has a greater internal area than would be the case if adhesive tape were used. The holder produced by the new method also is such that it does not require the additional cost of printing in order to mask for cosmetic purposes the adhesive tape.
The holder may be one which has four sides, and in which there are one of the closed sides and three of the open sides. Such a holder may be in the form of a folder.
Alternatively, the holder may be one which has four sides, and in which there are two of the closed sides and two of the open sides. Such a holder may be in the form of a sleeve which is open at both ends.
Alternatively, the holder may be one which has four sides, and in which there are three of the closed sides and one of the open sides. Such a holder may be in the form of a pocket which is open at one end.
The holder may be a single holder with a single reception area being formed between the first and second layers. Alternatively, the holder may be a multiple holder with a plurality of reception areas being positioned on top of each other, and with each reception area being formed between the first and second layers.
Alternatively, the holder may be a multiple holder with a plurality of reception areas being positioned side by side, and with each reeption area being formed between the first and second layers.
Alternatively, the holder may be a multiple holder with some reception areas being positioned on top of each other and some reception areas being positioned side by side, and with each reception area being formed between the first and second layers.
The holder may be one in which the first layer is made from a transparent material which forms an upper layer during use of the holder. The transparent material is preferably transparent polyvinyl chloride. Other suitable and appropriate plastics materials may be employed.
The holder may be one in which the first layer contains at least one liquid and air, and in which aesthetic patterns are produced by pressing on the first layer. If the first layer contains more than one of the liquids, then the liquids are immiscible liquids.
The holder may be one in which the second layer forms a base layer during use of the holder. The second layer may be made of a foam material. Other suitable and appropriate types of materials including flexible hard surface sheet materials may be employed.
The second layer may be made from a non-slip material.
Alternatively, the second layer may be provided with a non-
slip coating. Alternatively, the second layer may be provided with at least one self-adhesive pad for avoiding slipping of the holder on a surface during use.
The barrier sheet may be made from any suitable and appropriate material that prevents the welding of the first and the second layers, together during the construction of the holder. Preferably, the barrier sheet is made from polyethelene. The holder may be produced with the welding being heat welding, ultrasonic welding, or any other suitable and appropriate type of welding.
The holder may be produced in a wide veriety of different shapes and sizes for a wide variety of uses.
Thus, for example, the holder may be produced as a mouse mat, a desk mat, a coaster, a menu holder, or a wine list holder. Embodiments of the invention will now be described solely by way of example and with reference to the accompanying drawings in which:
Figure 1 shows a known holder for an insert in the form of sheet material; Figure 2 shows a first holder of the present invention; Figures 3, 4 and 5 illustrate the production of the holder shown in Figure 2; Figure 6 shows a second holder of the present invention; Figure 7 shows a third holder of the present invention; Figure 8 shows a fourth holder of the present invention; Figure 9 shows a fifth holder of the present invention in an unfolded form; and Figure 10 shows the holder of Figure 9 in a folded form. Referring to Figure 1, there is shown a holder 2 for an insert in the form of sheet material. The holder 2 comprises a first layer 4 and a second layer 6. The holder 2 is for use as a mouse mat. The first layer 4 forms a top layer which is made of transparent mark- resistant polyvinyl chloride. The second layer 6 forms a bottom layer and it is made of a synthetic foam material which may be 3 - 5mm thick. The holder 2 has four sides as shown. One side '3 is a closed side. The holder 2 is open on its other three sides as shown in Figure 1.
The closed side 8 is formed by sticking the first and second layers 4, 6 together using double sided adhesive tape 10. During use, the holder 2 will constantly be opened in order to insert sheet material (not shown) between the first and the second layers 4, 6. In order to ensure that the first and second layers 4, 6 remain stuck together along the side 8, the adhesive tape 10 is wide and is typically 30 - 40mm wide. As can be seen from Figure 1, the adhesive tape 10 thus occupies quite an appreciable amount of the surface area of the holder 2. Thus the adhesive tape 10 substantially restricts the reception area 12 which is available for receiving the sheet material.
Also, with the first layer 4 being made of the transparent mark-resistant polyvinyl chloride, the adhesive tape 10 does not look very nice when seen through the first layer 4. Therefore the first layer 4 has to be provided with printing over at least the area occupied by the adhesive tape 10, in order to mask the adhesive tape 10 for cosmetic purposes. This printing represents an unwanted cost in the manufacture of the holder 2.
Referring to Figure 2, there is shown a holder 14 for an insert in the form of sheet material (not shown). The holder 14 comprises a first layer 16 and a second layer 18.
The holder 14 is one in which there are three closed sides 20 and one open side 22. As can be seen from Figure 2, the holder 14 is in the form of a pocket which is open at the side 22 for receiving the sheet material.
The closed sides 20 are formed by welding the first and the second layers 16, 18 together. The open side 22 is such that it is kept open during the welding of the closed sides 20 by the positioning of a barrier sheet 24. More specifically, the barrier sheet 24 is positioned along the open side 22 and between the first and the second layers 16, 18. As best seen from Figure 4, the barrier sheet 24 extends beyond a welding head 26 which welds the first and the second layers 16, 18 together. Thus the welding head is able to weld the first and the second layers 16, 18 together along three sides which become the three closed sides 20, but not along one side which becomes the open side 22.
The holder 14 may be made for use as a mouse mat. In this case, the first layer 16 may be made of transparent polyvinyl chloride or any other suitable and appropriate weldable material. The second layer 18 may be made from a white-faced expanded material or any other suitable and appropriate material which has non-slip properties for ensuring that the holder 2 does not slip on a support surface such for example as a surface of a desk or table.
If desired, the non-slip properties may be achieved by coating the second layer 18 with a non-slip mateiral. Non-
slip properties may also be obtained by use of self-
adhesive pads.
As can be appreciated from Figures 2 - 5, the holder 14 can be made in one single operation using a welding
machine having a welding head 26 which is in the shape of the finished holder 14. The welding machine may be a high frequency welding machine with the welding head 26 being an electrode. If desired, the welding machine may be a heat welding machine. After the welding is effected, the produced holder 14 is removed from the welding machine, and the barrier sheet 24 together with any waste material may be disposed of. The barrier sheet 24 is preferably made of polyethelene but other materials may be employed if desired. In Figure 2, the welding is showing as welding 28. Referring now to Figure 6, there is shown a holder 30 having two closed sides 20 and two open sides 22. Such a holder 30 is in the form of a sleeve which is open at both ends. Figure 7 shows a holder 32 which has four sides, and in which there are one of the closed sides 20 and three of the open sides 22. The holder 32 is thus produced in the form of a folder.
Figure 8 shows a holder 34 which is a multiple holder having two reception areas 36. Each reception area 36 is deficed by three closed sides 20 and one open side 22.
Figures 9 and 10 show a holder 38 which is a multiple holder having three of the reception areas 36. Each reception area 36 is formed by three of the closed sides 20 and one of the open sides 22. Figure 9 shows the holder 38 in an unfolded condition. Figure 10 shows the holder 38 in
a folded condition. In the unfolded condition shown in Figure 9, it will be seen that the reception areas 36 are positioned side by side. In the folded conditon of the holder 38 shown in Figure 10, it will be seen that the reception areas 36 are positioned on top of each other.
Although not shown for simplicity of illustration, the reception areas 36 are all formed between first and second layers 16, 18.
It is to be appreciated that the embodiments of the invention described above with reference to the accompanying drawings have been given by way of example only and that modifications may be effected. For example, the holder of the present invention may have one or more reception areas as desired. Each reception area may have one or more open sides as appropriate. It is possible to have reception areas for the storage of one or more of a compact disc, a photograph, a brochure or other sheet material. Generally, the insert may be paper-based as in the case of a photograph or a brochure, or the insert may be such that it has an appreciable thickness and it may be made of a plastics material such for example as in the case of a compact disc.
The holder of the present invention may be produced such that the first layer contains at least one liquid and air, and in which aesthetic patterns are produced on pressing the first layer. The holder may be manufactured to open like a book. The holder may be manufactured so
r that it is Z-folded or concertina folded. Such a construction may enable six or more printed surfaces to be visible. Where the holders comprise more than one reception area, then the holders are preferably made in one manufacturing step with an appropriate welding head, but the reception areas may alternatively be made in separate items which are subsequently welded together.
The holder of the present invention can be personalized by print on any of its layers. The holder can be produced to be suitable for a wide variety of uses.
Thus, for example, the holder can be produced as a mouse mat. It may be scaled up for use as a desk mat, or scaled down to make a coaster. If the holder is to be in the form of a coaster, then the first layer will normally be made of a heat resistant material. The holder may be used as a table mat, a menu holder or a wine list holder. The holder may be utilized to hold a calendar or a calculator. The holder may be used as packaging for inserts in the form of computer software, computer discs or digital versatile discs. If the holder is supplied with unprinted inserts, then the unprinted inserts may be customised by users, which may be especially advantageous for schools and colleges, and for domestic users, especially those with digital cameras.
