Description

OPENING DEVICE, VINTAGE V CLOSURE FOR PACKAGING

SECTOR OF THE TECHNIQUE

Opening and closing device for containers of liquid, granulated or powdered products, preferably composed of several layers although it can be used for other types of containers with similar formats but of different material, for example plastic, etc.

Designed primarily for use with food products although it can also be applied to other products of similar densities.

STATE OF THE TECHNIQUE

Currently, threaded nozzles are widely used with different sealing methods, as examples we cite the following patents: PCT / CH2003 / 000328 with publication number ES2270005 (04.01.2007) and applicant SIG Technology LTD (CH), PCT / EP2007 / 053046 with publication number ES2339892 (05.26.2010) and applicant SIG Technology AG (CH), E04104029 with publication number ES233500 (18.03.2010) and applicant Tetra Laval Holdings & Finance SA (CH), E92104364 with publication number ES2082254 (16.03. 1996) and applicant Tetra Laval Holdings & Finance SA (CH), E03425740 with publication number ES2280726 (16.09.2007) and applicant Tetra Laval Holdings & Finance SA (CH).

We cite another model of non-threaded nozzle with seal rupture system, patent U200901050 with publication number ES1070864 (10.11.2009) and applicant Betapak S.A. (IS).

Airtight opening and closing systems without nozzle, with pouring element of type E92111411 with publication date ES2082283 (16.03.1996) and applicant The Procter Gamble Company (US), can also be seen on the market.

Patents of less generalized use in the market and that act as independent parts to the container itself, to be placed in the peaks formed with the fold of the container such as P200101230 with publication number ES2185485 (04.04.2003) and applicant José Luis Díaz Guereu García (ES), or P9802682 with publication number ES2154202 (16.03.2001) and applicant Enrique García de la Infanta (ES).

We cite other previous examples with eyelash-type closure elements that protrude from the closure cover, U8801766 with publication number ES1008707 (16.05.1989) and applicant Daría Braceo Barcina (ES) and an improvement to the previous P9202278 with publication number ES2079260 ( 01.01.1996) and applicant Mario and others Braceo Barcina (ES).

 layers used for dairy liquids, juices, etc. as well as others of higher viscosity type sauces, etc., and can also be used for powdered or granular products such as sugar, cocoa, etc.

The piece object of the invention is unique although different parts can be distinguished. It consists of a cover formed by a flat surface with a flange of

 edge thus eat another inner wall for the hermetic closure ° of the container, a pouring element closed on its lower face by means of a comma-sealed membrane, embedded in the container and pinch1 to be removed in its first use while breaking the seal and torque finally a flat base perforated in its central area to fit the pouring element, acting as a union of the piece with the container,

 hinged to the lid and attached to the pouring element by the narrowing of the thickness of the piece.

The pouring element carries along its lower edge a stop formed by an eyelash pierced in practically all its perimeter where live teeth can penetrate which hang from the underside of the joint base can

 container, cracking the membrane that acts as a seal and placing it inside the container being suspended from one of its edges, the teeth of the opposite end to which the membrane hangs are longer to ensure the seal falls. A stop located in the area of greater surface of the wall of this element can fit the base of the container preventing the pouring element from coming back down once

 Open the container.

By not introducing any threaded or similar element that protrudes excessively from the surface of the container and carrying the spill piece inside the container during the entire storage, transport and distribution process, instability problems are solved by supporting some containers on other a surface

 regulate without protruding elements that create an unstable point for each stacked container, while eliminating air spaces between the stacked rows optimizing their storage and transport.

As an advantage over other devices that use a discharge nozzle, we can achieve a pouring element that rises as a mouth

 With a slight curved recess in the surface of the liquid outlet end, avoiding splashes caused by the entry of outside air and favoring the discharge.

On the other hand, as it does not contain threaded elements, it facilitates the opening of the container to users with difficulties in exerting the pressure required to unscrew the tap & in its first use.

It is achieved with a single indivisible piece a hermetic closure °, the rupture of the seal membrane being suspended from an edge inside the container without generating waste and an overflow spout to favor the discharge of the

liquid °, thanks to the inclination of the projecting wall of the pouring element, the concentration of the contents of the container on the exit surface of the same is avoided, achieving greater hygiene once the container is opened, a characteristic that differentiates it from the existing pouring mouths that remain on the surface of the container, in which it is necessary to extract a film to pre-seal and when not rising at the end of the return they generate accumulation of the contents of the container especially when they have a higher density such as the rooms. By lifting the sealing cover ° and prior to the extraction of the pouring element, the user can see the sealing membrane at the bottom of the closure, making sure

10 so that the content has not been manipulated after packaging. It differs from other devices where, as in this case, the container composed of several layers is perforated at the time of filling when the closing piece of plastic material is placed, preferably by ultrasonic welding prior to the manipulation of said container, so how much

15 the inner walls of the closure object of the invention such as the membrane located at the base thereof protect the perforated section avoiding leakage of the content in the permeable layers of the cornposition of the container.

The object of the invention characterized by the details presented in claim 1, has the comfort for the user of not requiring the use of an independent part for opening the container as in the systems

raised to be placed in the peaks formed by the folds of the container.

 shape of the upper face of the pouring element (2) with an edge flange as well as another inner wall coinciding with the liquid outlet opening () with a slightly inclined section with respect to the vertical as the upper edge of the wall occurs of the pouring element (2) to achieve the hermetic closure ° of the container, a pouring element (2) closed in its lower face by means of a membrane (3) as a seal of impermeable material that also prevents the exit of gases already known in the state of the technique, embedded in the container and mewll by means of a beveled cut that reduces the thickness of the plastic material ° without arriving from the piece to be extracted in its first use and finally a flat base (5) with sufficient support surface in the composite container to achieve its perfect adhesion preferably by ultrasonic welding, widening at the opposite end to the pouring of the liquid () to be hinged with the cover (1) of hermetic closure ° and acquiring the shape of the same for its perfect fit in the closed position, perforated in its central area to fit the pouring element (2), acting as union of the piece with the container, with the lid (1) of hermetic ° closure and with

 to the pouring element (2).

The pouring element (2) carries along its lower edge a stop (4) formed by a perpendicularly folded flange, pierced in practically all its perimeter, leaving the ends without timing so as not to divide the pieces, where teeth penetrate with living edge (6) that hang from the underside of the joint base (5) with the container, with a decreasing height from the end where the spill takes place towards the joint edge with the base piece (5) that supports on the container, cracking the membrane (3) that acts as a seal and placing it inside the container being suspended from one of its edges. A stop (7) located in the area of greater surface of the wall of this element (2) achieved by a slight widening of the section of the wall in said area with a smooth curve that facilitates its exit through the mouth of the container and sufficiently flexible to get it to recover its initial form once it has completely left the inside of the container where it fits with the base (5) of external support preventing

the pouring element (2) goes back down once the container is opened.

 In this way a simple opening of the container is achieved by pulling first

place of the cover (1) for hermetic closing ° and making a second movement

exclusively on the first use of the container, pulling the pouring element (2) from

the recess that forms at the edge of its pouring end, causing the

seal rupture (3) and the fixing of this element (2) in its outer position.

 The opening, pouring and closing device is made of plastic material, being manufactured

by means already known, preferably in mold and with injection as

unique piece. Said piece will be joined with the container preferably by welding

of ultrasound being able to use other methods also known in the art with hot adhesive.
