Foldable plastic material

Pedicure, technician, technician;

V 'e' '- chaotic material of the trait,' no matter what?

me sue the overpowered en-Ian of claim 1.

Applicable to such edicts are known in the Swiss patent / 5725. Accordingly, both related parties are interconnected between thin objects, to which the main values ​​of symmetry fall. The intermediate elements are in the shape of a bending spring, which exerts double folding forces on both of the connecting parts, so that they are pressed from a position of equilibrium or at? the open blue or closed Jesse. The pulsating intermediate elements are connected according to FIG. 8 to 15 of the Swiss patent in a hinged fashion with the aid of two minutes of twist after the connecting parts. The axes of all the three minute rotors lie parallel to each other.

A well-known field of application of double rotors of this kind are bottle caps, manufactured: a pressure-molded molding to form a body. Kopepai executed by. Figs. 1C to 15 of the Swiss Patent are not suitable for such application, since the intermittent data (from 62 to 76) encompasses the main axis (minus 6). the real-

Patents may be applied to closures, provided they have relatively relatively wide openings in at least one of the two connected parts, provided that the housing of the interlocking element (e.g., number 42) is served. The evolving intermediate element must therefore be separated by slots, extending transversely along the axis, on one side and in part on the other also connected.

By opening, where the housing for the pulsating intermediate must have a predetermined length, it is substantially or unaffected by the impedance. shafts: so as to be relatively easy by turning one of the connecting parts such as the other cross-axis of the main shaft.

In a bottle with a double-barreled flask or similar, the lower portion, which is intended for placement on the mouthpiece, is generally enclosed by the upper portion thereof with a head / plate, or which has an ejection or ejection opening. Should Housing \ 's Pulse Intermediate Have To Be Stolen From It?

: within:

relatively large aperture of the cover, on the other hand opening within the lower part also. If we failed to do so, the fine lines, the coaxial coaxial axes and the hinged joints of both connecting hands, would push each other relatively well outward. That's it

9 (If an unsatisfactory form, on the aesthetic side, would on the other hand be highly improbable in the twisting or stamping with the aid of ordinary propulsion machinery,

<img file="GR75144B_D0003.tif" />

then that partially protrudes into the plaque head. This, however, limits the capability of forming caps. Can't we make stoppers, okay? -compared to a relatively large diameter for relatively large pouring openings and inappropriate components .

Finally duplicate rotors:

* The surface, or for this purpose of operation of the parts connected by the rotor, must be affected little or no by the connected parts. However, for example, stoppers must be able to be operated at all times. of the content.

Always these are achieved simultaneously by a double rotor according to claim 1. (* Bv is then taken into account or formulated in the claims).

* The spring operation necessary for the folding process may be achieved by pulsing the intermediate element, intermediate elements or other pieces of the double rotor, e.g. of one or both of the related parties. Importantly, in terms of subtle rotations, the interconnecting elements after the "interconnected parts" do not extend parallel to each other, but diverge so that the interconnectors cover a planar or three-dimensional triangular surface. * The necessary symmetry and symmetry is achieved by providing at least one such intermediate element and the other joint hinge which has the main symmetry axis. * The other joint article may be in the case of a normal normal spinner, but preferably a second intermediate element which is connected to the connected parts by obliquely extending thin spindles.

- 6 seconds, when they end up in the form of each other along these flat edges and form an unobtrusive joint). It should be relatively long with a duplicate rotor, that is to say, in an elongated box, but no more than two such intermediates may be provided, in particular ten pairs of intermediates.

Slower rotors, they connect directly between the two connected parts, as with established technology, it is not necessary at all. * Folding operation can also be performed on the oblique slip rotors. It may, however, have at least a shorter or longer slender rotor, which coincides with the main axis of symmetry. In other cases the main axis of symmetry exists as the rotational mass, but it is not created by a particular fine rotor.

A folding swivel according to the invention no longer requires openings or both of the associated parts. * On the other hand, the slanting spindles between the abutting slots may be longer than those of the already known slip rotors with double swivels. For both limbs, the ability to withstand or twist unintentionally increases. By omitting openness the scholar has more freedom in shaping. * The twin swivel provides a satisfactory aesthetic impression. The intermediate elements are configured and arranged so that in cases of use of the cartridge they do not protrude outwardly or protrude at least.

Duplicate rotors according to the invention are thus formulated, so that an insertional equilibrium position Z (break point 1) can fall into the normal folding path. Then care or function of the spring both of the position of indifferent equilibrium for opening or closing. * The position of different equilibrium may also be positioned by a suitable construction so that the connected parts can only be opened or closed only.

* Use of the rotor according to the invention is not limited to means of packing only. Many possibilities are available, e.g. in electronics, electronics, automotive, furniture, etc.

The rotor may also be manufactured as an independent structural element, which is subsequently combined with a separate product. Example: furniture door swivel.

Embodiments of the invention Intermediate elements 6 in the form of expandable grooves are particularly suitable for the manufacture of bottle caps. The grooves may have various cross-sectional shapes and vibrate, depending on the shape of the closure, pointing inward or outward, when the closure is closed, and there is always the possibility of accommodating these when studying in the outer circumference.

At the interface 11 the intermediate elements may be shaped as elastic elements, which live to perform these spring functions, at least of the connected parts being formed near the major symmetry of nitrogen. This results in the desired folding operation.

I don't really need a spring-

- 8 According to claim 13 or the invention, it is applied to the manufacture of duplex rotors by deep hollow packing. To prevent breakage of the deep hollow material - e.g. PVC (polyvinyl chloride) or polystyrene - in bending points, the intermediate elements may be provided with at least two deep hollow grooves, each of which undergoes part of the change of direction required by the folding process.

There are 17 grooves provided in the claim, extending longitudinally toward the main axis, there meeting the flat ends of two intermediate elements, but having at least one bent groove * as appropriate or each pair of engagement motions across the main axis so that, e.g. when closed or packaged, the transverse grooves! Some have been jammed in the package, when the package is not open;

First form of execution

Figures 1 to 3 show duplicate rotors, all of which are number 3 and gilt

<img file="GR75144B_D0008.tif" />

pressurized pressure-to-piece cylinder stopper e.g. of polypropylene. The duplicate rotor has two folding parts 1 and 2, of which the folding part 1 is formed as the base of the bottle stopper for mounting on the neck of the bottle, while the folding part 2 is a cover for the base seal. The geometric principal axis is denoted by the number 4. * The base 1 has a wide aperture 6 and the folding part 2 towards the hinged annular sealing lip.

* This swivel has two intermediate elements 5, formed as grooves of approximately P. In both intermediate elements narrows towards the main axis 4 to point 7, the text being the axial axis 4 and a symmetric plane 12 {Fig. 3). to the shaft axis.

The intermediate elements 5 are connected by slider rotors 9 and 10 with both of the duplicate parts 1 and 2. Each of the slider rotors 9, 10 is continuous from the left wide end of the left intermediate element 5 (Fig. 2) to right wide end of the right intermediate element 5 · Each describes a curve in space, which_a describes on one side a arc when looking from one side to the other does not completely or roughly coincide with the cylindrical wall of the closure.

The main rotor, connectors directly between the two duplicate parts, exists only in the region of point 7 and is only slightly short in length. It ends up seamlessly on both slim turns 9, 10. In other forms of execution it can be completely omitted by the master; then there is a point in this case

n

- 11 about geometrical main nitrogen, meaning that there is no need for a main rotor as a body.

The intermediate elements 5 are configured in this case to form cross-sectional bending sheets. The duplicate parts of the position according to Fig. 1 are rotated according to Fig. 2, but the intermediate elements 5 are bent almost to the top parties take a different balance (dead mark). * The intermediate elements therefore tend to return to their original positions and push duplicates_a places you are in a closed position.

In this embodiment, the flexible intermediate elements 5 are directed upwards (Fig. 1), when the closure is open, while there is an outlet inside it (Fig. 2), when the closure is closed. Neither of the parties is outwardly impressed and aesthetically pleasing.

Due to the length of the thin revolvers 9,10 there is a mechanically stable mechanism, even by twisting one duplicate to xd later, especially when the cap is open, only difficult to handle.

Second form of execution

Figs. 4 and 5 show a stopper with a double swivel, leaving only the cover open. * In the first embodiment the intermediate elements 5 are relaxed at both extreme positions, the intermediate elements 5.1 are relaxed in this respect Fig. 4 only the open position, otherwise not having the closed position.5 you do it to the maximum. The cover is assembled in the closed position by any lock, e.g. of the opening 6) and of the lip sealant 6a

Upon release of the lock, it jumps to that position, or which (possibly due to long-lasting deformation (in-flow)) corresponds to an angle of 90® and 180ύ. Within the connected part 1, within the base, cavities 14 are provided, which serve to accommodate the collapsed intermediate elements 5.1.

Third form of execution

In the form of the embodiment of Figs. 6 and 7, the intermediate elements 5.3 are reconfigured as bending sheets but not curved in the closed position, as in Fig. 2 towards an inner object other than outside and when it is open (Fig. 7) down. Otherwise the function is the same as described in the first example of execution. Again, there are fine rotors of 9 and 10 and at least a small real master value at point 7.

Change to the first form. execution

The flexible intermediate elements, as shown, may be shaped in section transversely to the geometrical main axis 4, but of a different geometric form also, such as a triangle, rectangle or polygon. Fig. 8 shows a form of execution with intermediate elements 5.4. To achieve the desired folding operation for opening and closing and achieving, though

I ·

- 13 within both of the connected parts, when the rotor is closed, the height X is preferably within each section cut transversely to the main axis, smaller than width 2.

In order to achieve mechanical operation, that is, the pre-tension (corresponding to the voltage for closing), the condition of 2 X CZ must be satisfied.

The fine rotors 9 and 10, which limit the intermediate elements, may be concave, (Fig. 9), convex (Fig. 1C) or straight (Figs. 11 and 12). In addition, there are many other form combinations. In all the examples described hereinbefore, the acute ends of the intermediate elements are turned against each other. Figs. 1 to 7.9 and 11 are silk-like. Contrary to Fig. 10 and 12, is projected between the acute edges of a straight main axis section 16 in the form of a rotor. the thin rotors 9 and 10 continue as the main rotor 16 and divide on the opposite end again by the two thin rotors 9 and 10. The thin rotors 9 and 10 may also continue in such a way that the area 16 near and adjacent to others. This is by analogy in the form of an execution according to Fig. 9.

In each of the embodiments described hereinbefore, a set of intermediate elements has been provided from time to time. Figs. 13 and 14 show folded rotors in a box, the integral part 1 having a double cover, the integral part 2. The straight fine rotor integral portions 16. * On the outer edges of the rotor shaft having intermediate elements 5.5, having a T-shape transversely to the geometrical

- 14 * * Both outermost inner elements are twisted along these broad ends outside and form a pair of intermediate elements together. In the mean, there are a further pair 17 in the present case, consisting of intermediate elements, twisted across their wide ends against each other. Neither of these intermediate elements project outwardly, when the box is open, thus corresponding to the form of rebuilding according to FIG. 6 and 7 and adjust the rectangular shape of the box when the latter is closed (Fig. 13).

Both intermediate elements 5.5 of pair 17 may be newly separated between slots 19 (Fig. 13) "extending transversely to the geometrical main axis. This permits, in particular where stiff material is concerned, the separation of both intermediate intermediate elements at the opening of the can.

The execution form according to Figs. 13 and 14 is further converted so as to omit either both the external intermediate elements or both intermediate elements arranged in the medium.

The intermediate elements should not be re-arranged in pairs. You are also ordering an unnecessary number of intermediate elements along the geometrical main axis are scalable. A modular hinge connection is provided along the main axis, a twin-screw rotor may also be fitted also with a single intermediate element.

Finally, special cases of apertures along the geometrical axis of the axis are arranged, especially between the thin or the wide ends of the intermediate elements. / 'A' ·. I.

- 15 Wednesday form of execution_

In the form of the embodiment of Figs. 15 to 18, intermediate elements 5.6 are traction elements, which are in no way or least elastic. * When the cap is open what the bolt elements are flat, and when the cap is closed apply exactly to the cylinder wall of the cap, they are then shaped like a mantle roller. * The folding function in this case is created by removing the elasticity of the wall of the connected part 2, i.e., the cover, near the point 7, i.e., the area 18,

In the process of folding through a position of "varying equilibrium, either the wall of the region 18 may be pressed into the radial direction or the area being pulled, the greater the area around the outside. It may also be crushed or region 7 between the two connected parts, or may be combined with more than one solution. In all cases, after crossing a position of "different equilibrium, a spring reset as a spring occurs.

In cases of embodiment, where the connecting part 1 is not coated with a plate head 20, but at this point, it can also be used in the wall of the connected part 1 to form a spring.

* As shown in Fig. 16, the fine rotors 10.1 of the connected part 2 do not end up in this case in the form of others, not least the finely rotated 9.1 of the connected part 1. * On the contrary, Fig. 16 has a finite 9 degrees you are a thin rotor 10.1. You / Off. applies to both lower slings. / j

- 16 * Instead, in a modified form of execution, the fine rotors may intersect, so that Fig. 16 upper slot 9.1 rotates in a linear fashion to the lower slot 10.1 and vice versa.

Fifth form of execution

Figs. 19 to 22 show a deep hollow sheet package suitable for deep casting

e.g. of polyvinyl chloride (PVC) or polystyrene. The deep foil sheet may have a significant thickness, so the thin swivel should be the thinner side. * The execution form has the ability to divide the required fine rotors into a plurality of parallel or slightly inclined grooves. * The packaging is subjected to deep landing at position 20 and 22. There are again two connecting parts 1 and 2, which in this case constitute the halves of the deep hollow packing. * Intermediate elements 5.7 have been provided, all of which are twisted along these wide edges to each other and enter without interruption.

* The function of the thin revolvers 9.3, 10.3 does not work in this case except for deep hollow grooves, the walls of which are formed by ribs 25 and 26.

The ribs 25 terminate on the walls 35 of "1 and 2" and the ribs 26 have the intermediate elements.

5.7.

Intermediate 5.7 is preferably full! before these broad ends, therefore near the / midpoints¹ . / * I • / 1 '

- 17 swivels, at one rib 28. * In the case of such ribs, one serves to strengthen the intermediate elements, and the other to form a transversely extending intermediate surface or 30 groove. between the two intermediate elements. At the grooves, which form very thin rotors 9.3 and 10.3 extend to each other in Fig. 7 to the narrow ends 32 of the intermediate elements.

During folding of the deep hollow pack, the closed position from the position according to Fig. 20 is positioned according to Fig. 19 "the grooves, which form thin rotors 9.3 and 10.3 and the narrow ends 32, as well as the grooves 25 and 26 each take part of the required bend. In this example of performing these grooves, observed in the direction of the arrow 34, they are in the closed position of the clover shape.

'The elastic locking function in this case is achieved by refolding the intermediate elements 5.7. * In this case, regions 36 of the socket walls engage near the wide ends of the spring members. In the open position of Fig. 20, both of the intermediate elements 5; 7 form a common, in-kind roofing surface, the roof of which is pointing downwards, i.e., to the outer side of the package. During the transition to the closed position both of the intermediate elements close inward. Again a kind of roofing surface is created, the one of which or the ceiling indicates to the inside this fall. * The intermediate surface 30 forms a joint. * The rotor function of the intermediate surface 50 facilitates the locking motion of the roof surface. / | It is preferable that at least the walls 35 of the connecting parts are flexible with a three-way tire, so as to be able to assume part of the spring operation during the folding process.

The connecting parts 1 and 2 of the deep hollow packing may have a tab 38, as shown only in Fig. 22.
