Abstract
Safety seal made of a plastic strip (1) fitted at one end with a thickening (3) housing a metal plate (8) fitted with an opening (9, 9', 9'') with a boundary slightly smaller than that of the area where the flexible strip is to be fixed (1) and which through peripheral tabs (11) leaning in the direction of introduction of the strip (1) allow its passage in one direction at the same time that they prevent its withdrawal. The strip (1) may be fitted with locking teeth or not, and is further fitted with a tab (10) and weakening lines (20) to facilitate its breakage, as well as grading marks (18) to allow establishing how many times it has been reused.
Description
- This invention refers to a security seal, of the type made up of a plastic or similar material flexible strip, ending on a wider section fitted with a passage through which the strip may be inserted, starting at its free end, and including strip holding means.
- The seals of the type mentioned may be used to fix labels and similar items, as well as to serve as informative elements in respect of the possible violation or undue handling of a given object or article.
- Within the seals of the type mentioned it is already known the practice of forming in the widening section of the strip a thicker part through which the passage made for the introduction of the flexible strip may be effected. This passage presents an intermediate narrowing, formed for example by way of a transversal step or tooth to which a certain inclination has been given, being the passage sized so as to allow the passage of the strip. On the other hand, the strip is fitted along a previously determined length with teeth sized and angled so that they may enter through the passage in the strip penetrating direction but they may not come out, as they would collide against the step or tooth that determines the passage narrowing, which shows an inclination or shaping opposite to that of the strip teeth.
- In this type of seals, forming the passage narrowing section presents many problems, due to the very small section of said passage. Furthermore, and due to the fact that the portion defining the passage and the teeth of the strip are formed by the same plastic material as the rest of the seal, the strip may then be pulled out by deforming the retaining elements, due to the plastic teeth giving way.
- The object of this invention is a seal in which the passage narrowing may be effected easily and above all safely, offering strip retention means, whether fitted with teeth or not, guaranteeing the integrity of the seal.
- In accordance with the invention, the passage through which the strip is introduced is fitted with a transversal metal plate fitted with an opening defining the narrowing of said passage. To this end, and in accordance with the invention, the area surrounding the metal plate opening shows approximately radial notches or cuts that determine flexible intermediate rims or tabs that are slightly inclined in the same direction, from their starting point. The internal edge of these tabs limits a minimal girth passage approximately equal to that of the section of the flexible strip lengths not fitted with notches or teeth, but smaller than that limited but said notches or teeth, if the strip is fitted with teeth and slightly smaller if not fitted with teeth.
- Thus, the toothed strip may slide freely through the passage, whenever through the narrowing run strip sections not fitted with teeth or notches. On the other hand, and whenever the strip slides in the direction of penetration through sections fitted with teeth or notches, the tabs or rims that limit the opening of the metal plate bend in the direction of their inclination, thus allowing the passage of said teeth or notches. If in this situation or position the strip is to be pulled out, the tabs act as retaining anchors against which the strip notches or teeth are supported, preventing them moving backwards. Also in the case of toothless strips the tabs flex allowing their entry, but if anyone tries to pull out the strip, the tabs stick into the strip preventing their movement backwards.
- The metal plate may be fitted, on the side towards which lean the rims or tabs, with a peripheral wall, thus adopting a bowl configuration.
- The metal plate opening may include a wider intermediate area, limited by narrower equal end areas and circular boundary. The flexible strip, on the other hand, presents, along the anchoring strip or strips, a thickening along its longitudinal edges determining two edges, upon which are formed equidistant and conical shaped peripheral offsets, aimed in the same direction, to define the anchorage notches or teeth.
- The plate opening may also show other arrangements that are in agreement with the strip section upon which it must act, so that it may present the shape of several aligned secant circles, or either Maltese Cross shaped, ideal for a circular section strip.
- Either one shape or the others may cooperate with toothless strips.
- The widening of the flexible strip has, in the thickened section in which the passage is located, a housing that leads outside and in which the metal plate or bowl is introduced. Thus, the plastic material strip is shaped approximately as the uniform passage section, later introducing in the fore mentioned housing the metal plate, which shall define the passage narrowing.
- The flexible strip may have along its length a graduation that would allow it to show that the strip has been cut and newly used. The flexible strip may also have, near its widening, an actuation tab that in cooperation with two weakening lines would allow manually actuated seal breakage.
- The characteristics and advantages of the seal object of the invention may be understood more easily through the following description, made with reference to the attached drawings, showing a non limitative execution example.
- Figure 1 is a lower plan view of a seal made pursuant to the invention.
- Figure 2 is a side view of the seal in the closed position.
- Figure 3 corresponds to detail A of figure 1 at a greater scale.
- Figures 4 and 5 are passage sections taken, respectively, as per cut lines IV-IV and V-V of figure 3.
- Figure 6 corresponds to detail P of Figure 1 at a greater scale.
- Figure 7 is a cross section of the flexible strip, taken as per cut line VII-VII of Figure 6.
- Figure 8 is an upper plan view of the plate defining the passage narrowing.
- Figure 9 is a plate longitudinal section, taken along the IX- IX cut line of figure 8.
- Figure 10 is a cross section similar to that of figure 4, with the metal plate mounted and the flexible strip introduced through the passage.
- Figures 11 and 12 represent views similar to those shown in figures 8 and 9 of a plate opening variation.
- Figures 13 and 14 represent views similar to those shown in figures 8 and 9 of a second plate opening variation.
- Figure 15 represents a view similar to that of figure 1 of a flexible strip variantion.
- Figure 16 represents a section of figure 15 given by the XVI-XVI cut line.
- The seal represented in figure 1 is made up of a
flexible strip 1, for example made of plastic material, topped at one of its ends by a rectangular boundary widening 2. This widening presents, as may be better observed in figure 2, athickening 3, in which a passage 4 has been effected, see figure 1, through which may be introduced thestrip 1, as from its end 5. - As may be observed in figures 3 to 5, in the
thickening 3 has been, set, besides passage 4, anintermediate housing 6, perpendicular to said passage. This housing leads outside and may be closed using a hatch formed from the widening itself 2 of the flexible strip. - Inside
housing 6 is introduced ametal plate 8, figures 8 and 9, presenting anintermediate opening 9, on which boundary are made approximately radial notches or cuts 10 limiting flexible intermediate rims ortabs 11. As may be observed in figure 4, all the tabs orrims 11 lean in the same direction.Plate 8 may be enclosed, on the side towards which lean thetabs 11, by aperipheral wall 12, adopting a bowl configuration which size corresponds to that of thehousing 6, described withreference 3 to 5. - In the described example, the
opening 9 presents a widerintermediate area 13, limited byend areas 14 equal to each other and of a lesser width, of circular boundary. - The
flexible strip 1 features, as may be observed in figures 1 and 2, along a given length, aslight thickening 15 along its longitudinal supports, determining ribs which, as may be better observed in figures 6 and 7, present peripheral conicalshaped surface offsets 16, all of them aimed in the same direction, to determine anchorage notches or teeth. - The
tabs 11 of themetal plate 8 are sized so that theinternal edge 17 of said tabs determines a minimal boundary passage approximately equal to that of the section of theflexible strip 1 lengths withoutribs 15 but smaller than that limited by said ribs. - With the constitution mentioned, forming the
flexible strip 1 with itswidening 2 and passage 4 does not offer any difficulty, given that said passage has a uniform section. Once the strip is shaped, at itswidening 2 is then introduced the metal plate orbowl 8 into thehousing 6, figure 10, closing saidhousing using hatch 7. In these conditions the seal is ready to be used, introducing theflexible strip 1, by its free end, through the passage 4. Upon arriving theribs 15 to the narrowing defined by theplate 8, its teeth or notches bend the rims ortabs 11 in the direction of penetration of the strip, whereas in the opposite direction they act as retaining anchors, thus preventing strip extraction. - Because the retaining elements are made up of
metal tabs 11, total safety is then obtained against the extraction of notches or teeth and, therefore against any seal integrity breaches. - As may be observed in figures 10, 11, 13 and 14, the opening of the
metal plate 8 may show various shapes. Thus in the figures 10 and 11, the opening 14' of theplate 8 has the shape of several aligned secant circles. This shape may be used with flexible strips featuring a section with as many ribs, which may also be fitted with teeth or not, or even with flat ribless flexible strips. - The opening 14'' presented by the
plate 8 of the figures 13 and 14 is specially designed for circular section flexible strips. - Finally figures 15 and 16 feature a seal in which the
flexible strip 1 shows flat thickening 15' and is fitted along its length with agrading 18, which mission is to reflect the number of times that the seal has been used, given that due to the strip having a considerable length, it may then be cut and reused. - The fore mentioned seal does also feature, in its flexible strip, close to the widening, a
tab 19 matching two weakeninglines 20 that do allow breaking off the seal easily without requiring the use of any instrument whatsoever. - It is clear that, on using as a flexible strip a flat profile, this must then present a cross section slightly bigger than the plate opening, so that on being introduced it would then bend the edge of the opening 9, 9', 9'', so that it constantly presses upon the flat flexible strip, so that whenever any effort is made to take it out, it would then stick into it preventing its displacement.
