DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a spout for bottles and similar containers that contain liquid or pasty products and have a neck which until the first use is closed off by a lid that can be pierced.
Spouts of this type are already known which comprise a body with means for fixing it unto the neck of the container and a hollow element to pierce the lid and to act as a spout for the distribution of the product contained in the container. On those known spouts the piercing element is generally formed by a screw element which is separate from the body and is rotated in order to pierce the lid.
This two-part construction complicates the manufacture and the putting on of the spout and increases the costs.
It also possible to make the piercing element and the body as one single part in the form of a rigid unit, in which case the piercing of the lid takes place by screwing the unit down onto the neck of the container. Such a spout can obviously only be used on threaded necks and not on necks on which the spout is put on by clicking it on. Furthermore, if the spout is not screwed down completely after piercing the lid, leads may occur between the spout and the neck. Moreover, an unintentional screwing down of the spout , e.g. during the handle of the containers, could cause an untimely piercing of the lid.
The present invention seeks to provide a spout with a piercing element for bottles and similar containers the neck of which is closed off by a lid, which spout can be made both as a screw down spout or a click-on spout, is easy to make and functions reliably without the risk of an untimely piercing and leaks. Another object of the invention is a simple and reliable unit comprising such a spout and a sealing cap in particular a sealing cap with together with the spout forms one single part and is connected to the latter by a hinge.
Thus, the spout according to the invention for bottles and similar containers that contain liquid or pasty products and have a neck which until the first use is closed of by a lid that can be pierced, comprises a body provided with means for fixing it onto the neck of the container, and a hollow piercing element to pierce the lid and to act as a spout for dispensing the product container in the container. According to the invention the piercing element arranged inside the body is made as an integral part of the body from a rigid plastic material and is connected to the body by a deformable angular membrane which until the first use is bulged upwards and which, if downward pressure is exerted on the piercing element with a view to piercing the lid, is deformed downwards to assume and then retain a downwardly bulge shape.
Because of the provision and special configuration of the membrane and the fact that the spout unit is made from a rigid plastic material, when the spout is fixed onto the neck of the container the piercing element is held in an inactive position above the lid of the neck, but by a simple downwardly pressure exerted on the piercing element this can be moved downwards to pierce the lid and then remains in the down position when the pressure on the piercing element is relaxed. This membrane accordingly ensures two stable positions for the piercing element, i.e. an inactive position above the lid and an active position for piercing the lid and for dispensing the product container in the containers.
The piercing element may advantageously be arranged concentrically to the body, which ensures that it retains this concentric position in the inactive position and in the active position.
within the scope of the invention the annular membrane may have either an inaccurate profile with double inflection, or a broken line profile with double inflection.
In the latter case it may be advantageous to provide the membrane with a circular weakened zone at each inflection.
If within the scope of the invention the spout is completed by a sealing cap which can be fastened onto the body by screwing or preferably by clicking on, it is advantageous if this cap has an inside sealing skirt wit
