Object of the Invention
[0001] As indicated by the title, the invention object of the present application consists
of a stopper for a box-type container with air admission, the purpose of which is
to pour out the liquid inside the receptacle without splashing or gushing.
[0002] The field of the art and scope of industrial application is comprised within the
sector of stoppers for opening and closing box-type containers, and/or toppers in
general for mouths of receptacles through which the liquid inside same is to be poured
such that it flows out in an even manner.
Background of the Invention
[0003] According to the analysis of the prior art, there is currently no product having
identical or similar features.
[0004] Therefore, the object of the proposed invention provides fundamental advantages for
the application thereof that are not covered by other similar or alternative means.
[0005] The stopper for a box-type container with air admission allows the fluid contained
in the container to be poured out in an even manner and without splashing and/or gushing.
[0006] Currently, all stoppers for closing box-type containers have a pour spout with a
single mouth for the outflow of the liquid from inside same, and therefore while the
liquid flows out, air must enter to take up the space left by the liquid as it is
poured out.
[0007] Since the admission of air and the outflow of the liquid occur at the same time,
an irregular flow of the liquid is generated as it flows out, which causes gushing
and splashing the area where the liquid is poured out such that the emptying of the
box is not easily controlled.
[0008] Document
US4930683A discloses a parallelepipedal flat-gabled package with a medial seam, and an area
in the gable prepared such that it can be penetrated or separated along a closed curve
and constitute a pouring hole. The package has a plastic pour-out structure with a
flange surrounding the pouring hole, rigidly secured to the outer surface of the gable,
and into the spout of which can be axially inserted a tube with a circumference that
matches the closed curve. It has triangular teeth along the surface that faces the
pouring hole, and a cap that can be repeatedly employed to close the spout, the inner
surface of the package being coated with a hot-adhering film of plastic. The closure-flap
cap is securely attached to the tube, by way of a connecting strip, and is articulated
to the tab on the pour-out structure, which is in the form of a spout.
[0009] According to the knowledge of the inventor, who is a skilled person in the art, the
object of the invention is novel, and due to the qualities and advantages provided,
said invention presents obvious industrial and commercial interest.
Description of the Invention
[0010] The stopper for a box-type container with air admission splits the mouth for the
outflow of the liquid contained in the box in two.
[0011] Both halves are identical, and this therefore allows admitting both air and a volume
of the liquid that is flowing out.
[0012] The space for the outflow in the stopper for a box-type container with air admission
is split into two identical parts, a lower part through which the liquid flows out,
and an upper part through which air is admitted. Furthermore, just as the liquid flows
out directly through the opening, air is admitted through a bent tunnel-like element
produced by a movable part which allows the admission of air but does not allow the
outflow of liquid contained in the box.
[0013] For all this to happen, the stopper is provided with elements that allow the screwing
on and cutting of the film membrane and aluminum sheet protecting the packaged liquid
until it is consumed.
[0014] Furthermore, it has been envisaged that the invention is comfortable and easy to
use, and in the same manner it has been envisaged that the elimination and disposal
thereof should also be easy and comfortable, without being an environmental hazard.

Description of a Preferred Embodiment
[0029] It can be seen in Figure 1 that the stopper (1) is the part that is manipulated and
used to open and close the mouth (4) for the outflow of liquid.
[0030] Before being opened, the stopper (1) is attached to the mouth (4) by means of a seal
(2) having a tongue (3).
[0031] By pulling on it, the precuts between the seal (2) and the stopper (1) are broken
on both sides with the mouth (4) and the stopper (1) being detached and the mouth
(4) being opened.
[0032] The mouth (4) is integral with a base (5) that is glued to the cardboard of the brik-type
container.
[0033] Figure 2 shows that in order to take the stopper (1) out of the mouth (4) and put
it back in, said stopper (1) has fingerprints (6) where, for greater comfort, the
index finger and thumb of the user are placed in the concave shape of said fingerprints
(6) to more readily remove the stopper (1) by making a riser.
[0034] Figure 3 shows that the stopper (1) for closing the mouth (4) is clipped on by gentle
pressure into the mouth (4), and as a result of the bending of the plastic material
of said stopper, its perimetral rib is clipped in the riser of the mouth (4).
[0035] When the stopper (1) is inserted in the mouth (4), it breaks the plastic film (25),
cutting the film (8) inside and thereby provides passage and access to extraction
thereof from the inner space of the box (9).
[0036] Figure 4 shows that the movable part (10) is pushed by the stopper (1) into the container
when the latter is closed, which generates a tunnel for the admission of air.
[0037] The movable part (10) moves on strips (11) integral with the butt end (12) which
is where it is supported and pushed by the stopper (1).
[0038] The box (13) of said movable part (10) has a lifting-type part (14) to prevent the
cut plastic film from going back and plugging up the opened hole.
[0039] Figure 5 shows that the box (13) has a closure (15) in the rear part of the movable
part (10) preventing the liquid from inside the box from filling up said box (13),
and it therefore allows only air to be admitted into the box through the upper part
of the box (13) while liquid is being poured.
[0040] Figure 6 shows that the inner part of the stopper (1) has two elements integral therewith,
i.e., the pushing element (17) which acts by moving the movable part (10) into the
container, and the cutting part (16) of the film of the box that makes the upper part
(22) through which the liquid inside the container is poured out.
[0041] Figure 7 shows that the guides (18) will lead the movable part (10) into the container
along the length of the box of the entry of the mouth (4) and on both sides thereof
and in a parallel and longitudinal manner.
[0042] Figure 8 shows that the cutting part (16) is provided on the front profile with toothing
(19) for tearing the inner film (25) and giving rise to the upper part (22) for pouring
the liquid from the box. The volume of liquid that is emptied out is replaced with
the air that is admitted through the lower part (23) of the mouth (4), without liquid
being able to flow out through it, despite the tilting of the box in order to pour
it out.
[0043] Figure 9 shows that the mouth (4) of the box is provided with a slot (20) along the
four sides of the front perimeter thereof. The stopper (1) has a clipping device (7)
in the form of a projection or riser, which is configured for being inserted into
the slot (20) of the front perimeter of the mouth (4) allowing thus the closing of
the mouth (4) once the required pouring service has been performed.
[0044] Figure 10 shows that the small bent sheets (21) resulting from the tearing of the
inner plastic film (25) of the container by means of the pushing element (17) and
the cutting part (16) do not block the admission of air into the container or the
pouring of the liquid, since they are bent into the container and extended, and facing
at each other.
[0045] Figure 11 shows the back of the base (5) of the stopper, which is configured for
being glued to the cardboard of the box by means of an adhesive (24). This figure
11 shows at the back of the base (5) the lower part (23) for the flowing of the air
and the upper part (22) for the pouring of the liquid, both parts (22,23) having the
same size, and therefore allowing the same amount of air to be admitted through the
lower part (23) than the volume of liquid that is poured out through the mouth (4)
of the container.
[0046] Figure 12 shows the film (25) inside the box.
