Abstract

The invention relates to a method for releasable mutual connection of two elements (1, 2), wherein the connection is formed by moving the elements relative to each other in a first manner and the connection is released by moving the elements relative to each other in a second manner which is not opposed to the first manner of movement. The first manner of movement can be a translation movement and the second manner of movement a rotation movement. The invention also relates to an assembly of elements for mutual releasable connection such as an outflow nozzle (1) and a cap (2), which elements are provided with a first set of co-acting members (11) for effecting a releasable connection when said elements are moved relative to each other in a first manner, and a second set of co-acting members (10, 12) for releasing the formed connection when the elements are moved relative to each other in a second manner which is not opposed to the first manner of movement. The co-acting connecting members can be adapted to form a snap connection (10, 12) when the elements are pushed over each other and the co-acting releasing members can be adapted to push apart the elements when they are rotated relative to each other.

Description

SNAP-ON CAP FOR A POUR SPOUT ****************************
The invention relates to a method for releasable mutual connection of two elements, in addition to an assembly of elements for mutually connecting in this manner. Numerous methods of releasable connection are already known. Mentioned by way of example are the screw connection, wherein elements are mutually connected by rotation thereof through a number of turns relative to each other, the bayonet connection, wherein the connec- tion is formed by sliding two elements over each other and subsequently rotating them roughly transversely of the sliding direction, and the snap connection, wherein the elements are connected by a temporary elastic defor¬ mation of at least one thereof. In all these connecting methods the movement required to release the connection is opposed to the movement with which the connection is effected. This is not practical under all conditions.
The invention therefore has for its object to provide an improved method for mutually connecting two or more elements. In such a method the connection is formed according to the invention by moving the elements rela¬ tive to each other in a first manner and the connection is released by moving the elements relative to each other in a second manner which is not opposed to the first manner of movement.
Preferably applied embodiments of the method of connection according to the invention are described in the dependent claims 2 and 3. The invention also has for its object to provide an assembly of elements which are suitable for mutual connection according to the above described method. In such an assembly of elements, in particular an outflow nozzle and a cap, the elements are provided with a first set of co-acting members for effecting a releasable connection when the elements are moved relative to each other in a first manner, and a second set of co-acting members for releasing the formed connection when the elements are moved relative to each other in a second manner which is not opposed to the first manner of movement.
Preferred embodiments of the assembly according to the invention form the subject-matter of the dependent claims 5-10.
The invention is now elucidated on the basis of two embodiments, wherein reference is made to the annexed drawing, in which corresponding components are designated with the same reference numerals, and in which:
Fig. 1 shows a partly sectional perspective view of an assembly according to a first embodiment of the invention in mutually connected situation,-
Fig. 2 shows a perspective view of one of the elements of the assembly of figure 1;
Fig. 3 shows a partly sectional perspective view of the other element of the assembly of figure 1;
Fig. 4 shows a view corresponding with figure 2 of an element of an assembly according to a second embodiment of the invention; and
Fig. 5 is a view corresponding with figure 3 of the other element of this embodiment of the assembly.
An assembly according to the invention comprises a first element 1, for instance an outflow nozzle (fig. 1) , and a second element 2, for instance a cap, for releasably connecting thereto. The outflow nozzle 1 can be detachably connected to a container (not shown) for a substance, for instance a liquid or a pasty mass. Envisaged here for instance is a cartridge of mastic. For this purpose the outflow nozzle 1 is provided on its underside with internal screw thread 4 with which a screw connection can be made with a container. The outflow nozzle 1 further comprises an internal passage 5 which debouches into an outlet aperture (not shown here) close to its tip 6 (fig. 2) . In the embodiment shown the outflow nozzle 1, which can be manufactured from plastic or a soft metal, is provided with three parallel cutting edges 7,8,9 along which the outflow nozzle 1 can be cut off to form an outlet aperture with a first, second or third diameter. In the embodiment shown the cutting edges 7,8,9 run at an angle relative to the centre line of outflow nozzle 1, whereby a uniform flow of the substance out of nozzle 1 can take place when it is moved along a surface. In order to enable firm screwing of the outflow nozzle on a container the nozzle is further provided with gripping ribs 14.
The outflow nozzle 1 and the cap 2 are further provided with co-acting members 10, 12 for effecting a snap connection when cap 2 is pushed over outflow nozzle 1. These co-acting connecting members are formed by a peripheral rib 10 on outflow nozzle 1 and a likewise peripheral rib 12 on the inside of cap 2. The cap 2 can hereby be snapped fixedly onto the outflow nozzle l in order to seal outflow nozzle 1 after use. In addition, the outflow nozzle 1 and the cap 2 are provided with co- acting members for releasing the snap connection when cap 2 is rotated relative to outflow nozzle 1. In the embodi- ment shown these releasing members comprise a wave-shaped guide 11 on outflow nozzle 1 and, complementary thereto, a wave-shaped cam 13 in the cap (fig. 3) . Due to the presence of this wave-shaped guide 11 and the cam 13 the cap 2 as it were "climbs" off the outflow nozzle 1 when it is rotated in the direction of the arrow Tl or T2, whereby the snap connection between the ribs 10 and 12 is disengaged and the meanwhile released cap can be removed from outflow nozzle 1 as according to arrow 0. For a better grip during the rotation movement the cap 2 is also provided with protruding ribs 15.
In a second embodiment of the assembly the outflow nozzle 1 is provided with a number of parallel helical guides 16 (fig. 4) and a plurality of bead-like cams 17 are arranged on the inside of the cap 2 (fig. 5) . In this assembly a snap connection between cap 2 and outflow nozzle 1 is also formed by sliding cap 2 over outflow nozzle 1 until the peripheral ribs 10, 12 snap together, while the snap connection can be disengaged by rotating cap 2 in the direction of the helical guides 16. Although this embodiment is structurally simpler than the first embodiment, it has the limitation that the snap connection can only be disengaged by rotation in one direction instead of rotation in the two directions Tl, T2 as in the first embodiment.
Although in each case the shown embodiments have separate members for forming the snap connection and release thereof, it is also conceivable to combine these members. For this purpose the outflow nozzle could for instance be provided with guide grooves, in which the bead-like guide cams as shown in figure 5 could then engage, wherein a number of the guide grooves could be provided with an interruption which could function as snap edge.
Although the invention is discussed here with reference to the connection of an outflow nozzle and a cap, it will be apparent to the skilled person that the underlying principle of the invention can also be applied in all kinds of other elements for mutual connection. All that is important is that the connecting members and releasing members mutually co-act such that the movements required to form and break the connection are not mutually opposing.
