Definitions

  • the invention disclosed hereunder consists of a screw-thread for bottles with asymmetrical neck, of among the screw-threads which define the exact position of the element to be screwed on: a cap without symmetry, or a spray gun.
  • the invention is conceived so that in all cases it facilitates the user reaching the end of the screw-thread and therefore its correct position.
  • the invention is characterised in the combined use of single entry screw-thread plus a section without helical pitch and a set of projections which increase the pressure and friction of the cylindrical body to be screwed on.
  • a firm grasp is easier when the centre of gravity of the bottle lies on the vertical line through this point of support, and such a situation is possible precisely when making use of asymmetrical necks which establish the offsetting necessary so that the centre of gravity lies where it is required.
  • the type of screw-threads habitually employed in these asymmetric bottles are based on the use of two differentiated sectors, one with a raised helical pitch for a quick engagement, for example in a quarter turn or less, and another sector with zero pitch which has the projections of the body to be screwed on at a position which assures the union between the two bodies.
  • This type of bottle is very habitual in guns for spraying products for use in the home and which come with refills, and the latter are sold separately. The user, after purchasing the refill is the person that fits the same.
  • the present invention surpasses this state of the art with a solution which prevents false securing of the screw by improving the entry in any position and establishing more secure tightening projections.
  • the invention object of the present specification relates to a screw-thread for bottles with asymmetric necks in which the stability of the union is assured without requiring intermediate particular efforts to surpass wedges and in which the entry of the element to be screwed on is not restricted to certain sectors only.
  • the screw-thread has various entries and is formed by interrupted projections in which principally three sections are distinguished:
  • the screwing-on operation has two stages, an initial entry stage with a raised thread pitch, and a second without pitch which includes an angle of rotation which carries the body to be screwed on to the final position.
  • the present invention incorporates additionally some projections distributed between the threaded elements which force a greater degree of friction with the cylindrical body to be screwed on acting progressively during the closing operation.
  • projections shall be termed pressure projections.
  • This increment in friction serves to maintain the element to be screwed on in the final position and offers the benefit of having a progressive force of retention.
  • the cylindrical body in which these horizontal projections are to be found progressively covers the thread of the bottle. It is in this progressive entry wherein the vertical pressure projections are covered and the force of friction between the two bodies to be screwed together is gradually increased.
  • each of the projections which have been distinguished in sections, and which define the thread have a pointed and rounded entry end.
  • this pointed projection presents a wedge-shaped vertical gradient which better facilitates the entry in whatever position, not only during manual screwing but also in automatic screwing when bottling in the production line.
  • Figure 1 shows a representation of the solution described as habitual in the state of the art wherein a section is shown of the thread of the bottle in development.
  • Figure 2 shows a representation of the invention wherein a section is shown of the thread of the bottle in development.
  • Figure 3 is a perspective of the neck of the bottle wherein the projections and the different inclinations are shown which the planes can adopt which delimit them.
  • the present invention comprises a screw-thread for bottles with asymmetric necks which offers the advantage of avoiding the need to apply particular forces before managing to secure the union between the bottle and the body to be screwed on reducing the dead sectors which give rise to false threading.
  • Figure 1 is a schematic representation of one of the solutions habitually employed in the state of the art and which serves as a basis for describing the drawbacks which it has and which are overcome by the present invention.
  • the screw-thread far from being single helical worms, is comprised of projections delimited by planes, many of them inclined. The latter are those which by means of arrows have their inclination indicated.
  • the number of vertical projections (10) need not necessarily be coincident with that of the screw projections (9) since they can vary according to the pressure to be applied, nor need they necessarily be coincident in projected height.
  • cylindrical projections (10) the cross-section of which forms an arc of a curve wherein in this case the support against the cylindrical surface to be screwed on is established over the length of a vertical line.
