Method for making seals, in particular for garments, and seal in accordance with said method

Abstract: Method for making seals, in particular for garments, in which there are supplied in series at intervals on an unbroken string (10) alternately bodies (11) and graft elements (12) in seats in said bodies (11) to constitute with the string (10) between them a connected plurality of seals separable by cutting the unbroken string. Said method is used advantageously to realize a separable unbroken series of seals each of which comprises a body (11) and at least one complementary graft (12) element insertable in a seat in the body (11) and connected by a section of string. To achieve this an unbroken string comprises alternately bodies (11) and graft elements (12) formed on itself at regular intervals. A specific form of embodiment calls for the alternate formation of a body (11) and two graft elements (12) turned in opposite directions so that each separate seal has a body connected by the string (10) to two graft elements therein.

Description: Seals are known, in particular for fixing labels or other to garments, made up of a flexible piece, e.g. a small cord, with clips which can be coupled inseparably at both ends. FR-A-2 548 296 discloses such a prior art seal. Ordinarily said seals are stocked in bunches or bulk and this results easily in tangling of the flexible sections or hooking of the projections of the clips. This makes the seals difficult to use because the seals must often be untangled resulting in considerable slowing of the operation of affixing the seals in position. The general object of the present invention is to obviate the aforesaid shortcomings and propose a method of making the seals and seals in accordance with the method which would be easy and quick to use without tangling problems. In view of said object it was thought to embody in accordance with the invention seals and method for making said seals as defined in Claims 1 and 9, respectively. To make clearer the explanation of the innovative principles of the present invention and its advantages in comparison with the known art there is described below with the help of the annexed drawings a possible embodiment as an example of the application of said principles. In the drawings: FIG. 1 shows a schematic view of an unbroken plurality of seals made in accordance with the innovative principles claimed herein; FIG. 2 shows a partial cross-section view of a seal of FIG. 1 separated; FIG. 3 shows a partial side view of a possible form of plug cross sections of the seal shown in FIG. 2. One method of making seals in accordance with the invention consists of fixing in sequence at intervals on an unbroken string the parts making up plug elements of the seal in such a manner as to obtain an unbroken series of seals each made up of complementary plug parts and the length of string separating them. It is thus advantageously possible to wind said series of seals on a spool or other support and avoid the possibility of tangling as with the seals of the known art. When needed for use, one seal at a time can be separated by cutting the string at the junction between two adjoining seals. With reference to the figures, in one example of embodiment applying said method as shown in FIG. 1 an unbroken string 10 includes plugs made up of bodies 11 and complementary plug elements 12 formed on said string. Each seal comprises a body 11 and two plugs 12 connected by the lengths of string between them. FIG. 2 shows a section of a separated seal with the corresponding plugs 12. As may be seen in said figure, the body 11 contains an internal hollow portion 13 shaped with teeth 14 complimentary to pliable fins 15 in the plugs 12. In this manner, upon insertion of a plug in the seat 13 the fin 15 is bent against the body of the plug and allows insertion of the plug into the body (as with the plug shown on the left in the drawing) until it passes the tooth 14 which then snaps outward (as with the plug shown on the right of the drawing) and prevent subsequent withdrawal. To avoid errors of orientation in insertion of the plug, and thus failure to engage the fin with the respective tooth, its section can be made with a form complimentary to the hollow portion in the body 11 and irreversible, i.e. it can be inserted in the hollow portion only in such a manner that the plug fin faces the tooth 14. To achieve this it is enough that two side walls of the plug be formed asymmetrically as shown for example in FIG. 3. Advantageously the bodies 11 and plugs 12 of the seals can be moulded directly in plastic on the unbroken string 10. Each time a seal is needed for use it is enough to unroll a length of string to the first group of elements making up a seal and cut the string between said group and the following one. In the example of the embodiment in figure 1 this means cutting the length of string between two facing plugs 12. The seal thus separated is made up of a body and the corresponding plugs connected by a length of string and can thus be placed in use by plugging the elements 12 in the body 11 in such a manner that the two lengths of string form closed loops passing through the parts to be connected with the seal, e.g. a button hole of a garment and an explanatory label. To minimize cord waste it is advantageous to place the elements of two successive seals as close as possible on the cord while leaving between them only the space necessary for cutting. From the above description the advantages of the present invention are obvious as it avoids the risk of tangling of the seals before use and makes positioning of said seals fast and easy. Naturally the description of an embodiment in accordance with the invention is given here as an example and therefore the scope of the invention is limited only by the claims. The system of fastening by snapping the plugs into the body of the seal can also be different. For example, it would be possible to embody plugs with two side fins arranged like an arrow for plugging in a corresponding seat of the body.

Claims: A seal, in particular for garments, comprising a body (11) and at least one plug element (12) insertable in a complementary hollow portion (13) in said body (11), said hollow portion (13) having a tooth (14) adapted to hold the plug portion and prevent it from being removed from the body after insertion, said body and said at least one plug element (12) being moulded alternately on a length of string (10), characterized in that said seal comprises two plug elements (12) facing in opposite directions along the string (10). Seal in accordance with claim 1 characterized in that the bodies and plug elements (12) are made of plastic moulded directly on the unbroken string. Seal in accordance with claim 1 characterized in that the plug elements (12) comprise projecting pliable fins (15) for fixed engagement with corresponding teeth (13) in the hollow portion (13) of said body (11). Seal in accordance with claim 1, characterized in that the hollow portion (13) has a plug inlet placed in the face of the body from which the string (10) leaves the body. Seal in accordance with claim 4, characterized in that the hollow portion (13) extends into the body parallel to the direction of a portion of the string (10) in the body. Seal in accordance with claim 3 characterized in that the plug elements (12) and the complementary hollow portions thereof are embodied with at least two opposing nonsymmetrical walls which prevent insertion of the plug elements in an orientation in which the fins and teeth (13) are not facing. Series of seals in accordance with claim 1 wherein the string continues unbroken to connect a plurality of seals. Series of seals in accordance with claim 7, characterized in that the plurality is arranged alternately with one body (11) and two plug elements (12) turned in opposite directions. Method of making seals according to claim 1 by moulding the seals at regular intervals on an unbroken string (10) to form a plurality of seals which are separable by cutting the unbroken string.
