OBJECT OF THE INVENTION
[0001] The present invention relates to a cap for water dispenser bottles, of those which
are incorporated to the bottle when the latter is upwardly located in an inverted
position and which couple to the downwardly located water dispenser by means of their
rupture due to the pressure exerted by a pin.
[0002] The present invention is characterized by the fact that the outer face of the cap
is smooth and its inner face has weakness lines in a radial direction.
BACKGROUND OF THE INVENTION
[0003] As is already well known, the systems known as water dispensers comprise a bottle
or carafe-like container upwardly arranged in an inverted position, which is provided
with a cap which couples with the water dispenser downwardly located.
[0004] Hitherto, different types of caps are known for this type of water containers. One
of these types of caps has a inner grooving through which the cap rupture is caused
by a pin of the dispenser which allows the entry of air into the bottle and the exit
of water. The grooving is outwardly covered by an adhesive seal which is removed at
the time of feeding to bottle to the dispenser.
[0005] The drawback of this type of cap is that dirt from the outside may accumulate in
the grooving which would go into the water upon placing he bottle in the dispenser.
[0006] The present invention solves the problem of dirt accumulation in the cap by means
of the use of a simpler cap which has a smooth outer face, without grooving or weakness
lines, preventing dirt accumulation therein.
DESCRIPTION OF THE INVENTION
[0007] The present invention relates to a cap for water dispenser bottles, of those which
are incorporated to the bottle when the latter is upwardly located in an inverted
position and which couple to the downwardly located water dispenser by means of their
rupture due to the pressure exerted by a pin.
[0008] The cap of the invention is characterized in that its outer face is smooth, that
is, it lacks grooving, weakness lines or any other groove that may retain dirt, its
inner face being that which has weakness lines which would favor the coupling of the
cap to the dispensing machine.
[0009] The weakness lines are located in a radial direction, there also being a circular-shaped
weakening in the center of the inner face of the cap. Upon placing the bottle in the
dispenser the rupture of the weakness lines would take place due to the pressure exerted
by a pin that enables the exit of water and the entry of air and thus the normal operation
of the water dispenser.
DESCRIPTION OF THE DRAWINGS
[0010] The present specification is complemented with an illustrative figure of the preferred
example and never limiting the invention.
[0011] Figure 1 is a perspective view of the smooth outer face of the cap in which the weakness
lines located in the inner face appear as dashed lines.
[0012] Figure 2 is a perspective view of the inner face of the cap.
PREFERRED EMBODIMENT OF THE INVENTION
[0013] The present invention relates to a cap for water dispenser bottles, of those which
are incorporated to the bottle when the latter is upwardly located in an inverted
position and which couple to the downwardly located water dispenser by means of their
rupture due to the pressure exerted by a pin.
[0014] The cap (1) of the invention is characterized in that its outer face is smooth, its
inner face (2) being the one that has weakness lines (2) for the rupture by the pressure
exerted by a pin during the insertion thereof in the cap. Said weakness lines are
located in a radial direction, there also being a circular-shaped weakening (2.2)
in the center of the inner face (2) of the cap (1). In the case of the preferred embodiment,
the cap would be introduced in the bottle by pressure, that is, it is a seal type
cap.
[0015] The essential nature of this invention is not altered by variations in materials,
shape, size and arrangement of the constituent elements, described in a non-limiting
manner, the latter being enough for a person skilled in the art to proceed to reproduce
it.

pin, characterized in that its outer face is smooth and its inner face (2) has weakness lines (2.1).
2. A cap for water dispenser bottles according to Claim 1, characterized in that the weakness lines (2.1) are in a radial position.
3. A cap for water dispenser bottles according to Claim 1, characterized in that there is a circular-shaped weakness line (2.2) located in the center of the inner
face (2) of the cap (1).
