SEALS AND, METHOD OF ATTACHING THEM TO 'rymc ELEMENTS Filed March 31, 1959 ATTORNEY atent flfice 3,fl9,276 Patented Nov. 21, 1961 SEALS AND METHOD OF ATTACHING THEM TO TYlNG ELEMENTS William Stelzer, Bloomfield Hills, Mich, assignor to Stolfel Seals Corporation, Tuckahoe, N.Y., a corporation of New York Filed Mar. 31, 1959, Ser. No. 803,259 8 Claims. (Cl. 40-316) The invention relates to seals and the method of attaching them to elongated members such as tying elements, and more particularly to interconnected seals made in strip form, and the method of separating single seals from a strip and attaching them to tying elements.
An object of the invention is to produce an inexpensive and tamperproof seal that lends itself for use with a manually or power operated device for rapid attachment to the strands of a tying element used in sealing articles or for securing price tags.
Another object is to produce novel seals in strip form that are securely held together and yet can be severed with a minimum effort by using a novel method.
Other objects and advantages of this invention will be apparent from the following description considered in connection with the accompanying drawing in which:
FIG. 1 is a side elevation of the seal strip;
FIG. 2, a front elevation thereof;
FIG. 3, a cross-section through the seal at the end of the strip shown partly closed by a curling die and punch;
FIG. 4, a cross-section through the seal adjacent the first seal held in a fixed guide element; and
FIG. 5, a perspective view of a seal separated from the strip and secured to the strands of a tying element.
Briefly stated, the present invention contemplates seals having tag and channel portions and connected side-byside at the channel portions along lines weakened in such manner as to facilitate or produce separation of an end seal as its channel portion is bent to apply the same around tying elements.
The seals are manufactured in gang strip form as shown in FIGS. 1 and 2, the seal strip 1 being formed from a single piece of sheet metal and comprising a channel section having a Web 2, an outer flange 3, and an inner flange 4 connected to a tag section 5. The tag section is a continuation of flange 4 and is bent away from the plane of flange 4, preferably to be more or less parallel with web 2, as shown. The tag section 5, which may receive identifying indicia or other marking, has a plurality of transverse equally spaced slots 6 extending through inner flange 4 partly into web 2 of the channel section. The outer flange 3 has notches 7 in alignment with slots 6 and extending through outer flange 3 a short distance into web 2. Web 2 is scored transversely, so that there is a weakening line 8 extending from each slot 6 to the corresponding notch 7. Thus the strip 1 is divided by the slots and notches into a plurality of interconnected seals a, 5b, 5c, etc.
In order to facilitate the separation of the seals as a result of or immediately following the application of each, the web is preferably weakened to the greatest extent adjacent to the slot 6, the degree of weakening becoming less adjacent to the notch 7. One method of accomplishing this is to progressively more deeply indent a score line 8 into the web as the line progresses from the notch 7 to the slot 6. It is also contemplated that the scoring may be done on both sides of the web. However, in a strip of seals, it may be desirable to prevent separation of the last end seal from the adjoining seal until such end seal has been moved into position for closing, in order to facilitate feeding of the end seal. For such purpose the scoring between such two seals may be less pronounced and of uniform depth on one side only.
In order to impart a certain rigidity and strength to the seal strip to prevent breakage from handling without sacrificing the ease of severing a seal from the strip for attachment to a tying member, the web 2 is preferably slightly curved, which is particularly beneficial when a very thin sheet material is used to form the strip. The rigidity of the seal strip can be further improved by alternately continuing the weakening line 8 on opposite sides of web 2, for example, by having a score mark on the outside of web 2 starting at slot 6 to extend a short distance along line 8, continuing on the inside through the central portion of web 2 (to which the line of numeral 2 points) and terminating on the outside again into notch *7.
The construction of the seal strip is contemplated to make possible a novel method of severance of the first end seal from the strip and attachment to the strands of a tying element. This method is illustrated in principle in FIGS. 3 and 4.
Referring to FIG. 3, the seal 5a is placed between a curling die 10 and a punch 11, and the strands 12 of a tying element are placed into the channel section, as shown. The illustration shows the die partly closed, the curling action being incomplete. The second seal 5b is held by guide members 14 and 15 as shown in FIG. 4 to maintain the original form. These guide members are fixed in relation to punch 11. Thus when the channel section of the first seal is being curled, it is gradually shear-torn from the strip, requiring a minimum amount of effort.
Because of the presence of the scoring adjacent to the portion of the seal being curled, the separation of such portion from the strip during such curling is facilitated. Furthermore, due to the progressive weakening of the connection in the direction of progression of the curl, as previously described, the curling operation in itself may produce complete separation of the seal, or so nearly complete that the movement required to separate is negligible. However, between the last pair of seals the connection is preferably of greater strength as previously described, in order to promote feeding of the last end seal into position prior to the breaking off of its adjoining seal.
In order to improve the tamperproofness of the seal, the curled portion of the latter may be curved and the central portion crimped as shown in FIG. 5 where numeral 18 indicates the crimped central portion of the curved curled channel section, making opening without breakage more diificult. For this purpose punch 11 is recessed at 16, and surface 17 of die 10 is curved longitudinally to cooperate with recess 16 to produce the curled crimped configuration.
Accordingly, it will be understood that the present invention includes seal members connected in a manner to form a strip from which individual seals are substantially or completely separated by the closing or application of the same, the seals being so interconnected that a strip of substantial rigidity and strength is formed but in such manner that separation is easily accomplished.
It will be obviousto those skilled in the art that various changes may be made in the invention without departing from the spirit and scope thereof and therefore the invention is not limited by that which is illustrated in the drawing and described in the specification, but only as indicated in the accompanying claims.
