Abstract

A coin wrapper comprises a jacket 1, formed as a truncated cone with a stiff bottom disc 2 at its narrow end, the jacket being of thin flexible paper 3 over only a portion of the circumference of the jacket 1 with the remaining portion being formed by a transparent strip 6, which joins the two longitudinal paper edges 4, 5 so as to form a window. The bottom disc 2 is made of or coated with heat- sealable material and has holes to prevent stacked wrappers from sticking together due to underpressure between the bottoms. As a tear aid, a grip tab 7 can be punched in the upper end of the transparent strip 6. Said strip can also be perforated for facilitating opening. Alternatively, a tear strip or string can be incorporated e.g. between an edge of the transparent strip and one of the paper edges 4 and 5. <IMAGE>

Description

SPECIFICATION Coin wrapper The present invention relates to coin wrappers for banks for example, comprising a jacket of a thin, flexible paper material and a stiff bottom disc in which the jacket has the shape of a truncated cone with the bottom disc arranged at the narrow end.

Coin wrappers are known per se and are used widely by most institutions which handle large quantities of coin. Swedish Patent Specification 21 6 129 describes a coin wrapper of the type mentioned in the introduction. In order to easily check the contents in the wrapper, the bottom can be a transparent plastic disc, or a window or a row of holes can be cut in the material forming the jacket.

One of the advantages of a conical jacket is that the wrappers can be stacked in each other. With a stiff bottom disc, the wrappers support each other so that they will not be deformed. The disadvantage is that the wrappers are difficult to separate because underpressure is easily formed in the spaces between the bottom discs.

It is difficult to break the wrappers now available when the coins are to be taken out. They are often opened by cracking the full roll of coins against an edge. This is noisy and can cause damage to the edge struck. Opening the wrapper by folding up the free end of the wrapper is more time-consuming and usually much too time consuming. This is not a very good method either, especially not for people with long nails.

The coin wrappers presently used are as a rule made of plastic-coated paper, which simplifies and reduces the cost of the manufacturing process. The jacket is made by laying the material around a mandrel, and then heat-sealing the overlapping, longitudinal edges to each other. The cost of coin wrappers of this type is however starting to become too high, due to rising costs of the plastic in the plastic-coated paper as a result of rising oil prices.

The purpose of the present invention is to achieve a coin wrapper which does not have the above-mentioned disadvantages.

This is achieved by means of the coin wrapper according to the present invention, which is characterized in that the paper material only extends over a portion of the circumference of the jacket, while the remaining portion consists of a transparent strip, e.g. of plastic, Cellophane (Registered Trade Mark) etc. which joins two opposing, longitudinal edges of the paper so as to form a window; that the stiff bottom disc consists of or is coated with a heat-sealable material; that the bottom disc is provided with one or more holes; and that a tear aid is arranged on the wrapper.

The transparent strip can be made of or coated with a heat-sealable material so that it can be joined to the jacket by means of a simple heating step. Alternatively, the strip can be provided with strips of glue for gluing onto the jacket.

The heat-sealable material in or on the bottom disc makes it possible to easily join it to the paper jacket in a simple heating step, with the jacket either being folded under the bottom disc or the bottom disc being pressed against the already folded jacket.

The tear aid can be made in several different ways. Preferably it has the form of a grip tab which is punched in the strip, with the punchings also functioning as tear initiations. The grip tab can also be a portion extending above the paper jacket, which can be combined with perforations of suitable length in the upper portion of the strip.

These tear aids make the coin wrapper substantially easier to open but still do not make it too fragile. It should stand up to being dropped on a marble floor for example, the type of floor which is common in banks.

Further characteristics and advantages of the invention will be evident from the detailed description below in connection to the accompanying drawing, of which Fig. 1 is a front view of a coin wrapper according to the invention with a punched grip tab; Fig. 2 is a view similar to that in Fig. 1 but with a projecting grip tab combined with perforations; Fig. 3 is a perspective view of the coin wrapper according to the invention showing the bottom seal together with another embodiment of the tear aid; and Fig. 4 is a view of the coin wrapper with a string as tearing aid.

Fig. 1 shows a first embodiment of the coin wrapper according to the invention. The coin wrapper consists of a truncated, conical jacket 1 and a bottom 2. The jacket 1 consists mostly of opaque material 3, preferably paper. The paper material however does not extend all the way around the jacket; there is gap between two longitudinal edges 4 and 5 of the paper. This gap is bridged by a transparent strip 6. The gap between the two longitudinal edges 4 and 5 can either be V-shaped, as shown in the Figure, or rectangular, depending on the method of manufacture. The strip 6 can be joined to the paper material either by heat seaiing or by gluing, and is preferably on the outside of the paper material.

The tear aid is in this case a grip tab 7, which is punched in the upper end of the strip 6. If the strip is made of Cellophane (Registered Trade Mark) for example, it is quite sufficient to have the punching serve as a tear initiation. With certain other materials however it may be necessary to make perforations in the extension of the grip tab to facilitate tearing of the coin wrapper. One must in this case however take into account the strength of the wrapper, especially if it is to be used for large coins.

Fig. 2 shows another embodiment of the tear aid. The strip 6 is longer than the paper jacket 1 and thereby forms a projecting portion 8. Two punchings 9 are made in this portion, which define together a grip tab 10. In certain cases, as was mentioned above in connection with Fig. 1, it can be advisable to arrange perforations 11 in connection to the grip tab 10. In certain cases it can be quite sufficient to merely allow the extension 8 of the strip to function as a grip tab, for example in coil wrappers for small, light coins, in which the heat seal and/or materials need not be so strong.

In both of the embodiments described above, in order for the grip tab to fulfill its function, after filling with coins the coin wrapper must be folded so that the grip tab is on top. This is however easily learned.

Said problem can be avoided by the embodiment shown in Fig. 3, which shows how the coin wrapper can be sealed at the bottom. The jacket 1 is folded around the stiff bottom disc 2, which preferably consists of cardboard coated with heat-sealable material. Holes 12 are also arranged in the bottom disc. This eliminates underpressure between the bottom discs when the wrappers are stacked in each other, so that they can be easily separated.

Fig. 3 also shows another embodiment of the tear aid according to the invention. A grip tab 13 is formed by a slot 14 along the bottom periphery and two slots 1 5 upward on the cylinder. To facilitate tearing, perforations 16 of suitable length can also be arranged here.

In Fig 4 the tear aid is a string 17. This string, which can also be a strip of the type used on cigarette packages, is in the coin wrapper shown in the figure applied between the strip and the paper material. This is however not a definitive characteristic; the string can instead by placed on the inside of the transparent strip or on the inside of the paper material.
