Abstract

The closure consists of a lower closure part, which forms a drinking and pouring neck, in addition to a closure cap, which is pivotally connected to the lower closure part by a hinge. The drinking and pouring neck sits in a planar disc, onto which the hinge of the closure cap is formed. Below the disc, the drinking and pouring neck is surrounded by a deformable wall that forms a cone or dome, said wall extending obliquely downwards from the neck and being connected to the outer edge of the lower closure part. The drinking and pouring neck projects beneath the underside of said deformable wall and the lower edge of said neck forms at least two piercing elements. A spacer strip is formed onto the lower edge of the closure cap by means of one or more material bridges that act as predetermined breaking points. The spacer band guarantees that the cap has never been opened.

Description

Plastic closure with drinking or pouring spout and Folscherch device

[0001] This invention relates to a plastic closure having a drinking or pouring spout and a foil dosing device which provides a tamper evidence and also serves to open a foil-sealed container or spout fitted with this closure without affecting the actual drinking water. or to touch the spout nozzle with your fingers. This closure is suitable for containers of all kinds, especially those made of plastic, composite board, glass, but also for tubes or other containers made of a combination of the aforementioned materials. It is especially suitable for contents of liquid or pasty consistency.

There are already a variety of plastic closures with a drinking or spout nozzle, which are commonly known as sports closures. They usually consist of a closure bottom, which is screwed onto a threaded connector, and a hinged thereto molded cap. In the center of the closure base, a drinking and pouring spigot is attached, which is axially displaceable for opening and closing. For initial use of the entire closure must be weggeraübt from the container, then the sealing film on the container neck can be torn away and then the closure is screwed back onto the container, after which the cap is removed or unfolded and the drinking or pouring spout releases. In other solutions, the sealing film is pierced after unfolding the cap by pressing the drinking and pouring spout axially downwards with your fingers. Because this the nozzle must be touched, this solution can Hygiene requirements are not fully sufficient. All these solutions are also designed in several parts, ie they are made of several, individually molded and then assembled together parts. These multi-part solutions are expensive and require complicated, space-consuming assembly systems.

The object of the present invention is therefore to provide a closure with drinking and pouring spout, which offers a Erstöfmungsgarantie with which the sealing film of a container or container equipped with it can be opened without the actual drinking or Discharge nozzle must be touched with your fingers and without the entire closure of the container must be removed. In addition, this closure should be made in one piece, ie in a single injection.

This object is achieved by a plastic closure with drinking or pouring spout and Folienstech device, consisting of a closure bottom part, which forms a drinking and spout nozzle, and a closure cap, which is connected via a hinge pivotally connected to the closure bottom is distinguished, and characterized in that the drinking and pouring spout sits in a flat disc on which the hinge of the cap is formed, that below the disc of the drinking and pouring spout is enclosed by a deformable wall, the forms an inwardly curved cone or an outwardly domed dome, and which wall of the nozzle leads obliquely downwards and is connected to the outer edge of the closure base, wherein the drinking and pouring nozzle projects beyond this deformable wall on the underside and its lower Edge forms at least two piercing elements, and that at the bottom of the cap a Distance tape is integrally formed over one or more acting as Sollbrrachstellen material bridges, wherein the spacer strip in the closed state of the closure cap surrounds the deformable wall and stands on the outer edge of the closure base, so that the cap after tearing this spacer tape is pressed down, while Niederdriickens the disc and of the drinking and pouring spout passing through it and deformation of the deformable wall.

In the figures, various variants of this one-piece closure for application to a plurality of containers are shown in different views. Based on these figures, the shutter will be described in detail and its function will be explained. It shows:

FIG. 9 Such a closure in cross-section, which is bounced on a sealed with a foil container neck;

FIG. Such a closure in cross-section, which is welded over the foiienversiegeite hole of a composite package; FIG. 11 Various containers and packages on which such a closure can be mounted.

FIG. 1 shows the closure 1 in the view from the side. It can be seen in turn from top first the closure cap 2, at the lower edge of which a spacer strip 5 is formed over some material bridges 14 intended to act as predetermined breaking points. This also acts as a spacer tape and is on the closure part 4, so that therefore the cap 2 can not be folded down or pressed down. At the bottom of the closure, a further spacer band 6 is formed over the material bridges 15. A lip 16 on the cap 2 helps to fold this up to open. On the other side of the cap you can see the hinge 21, via which the cap is connected to the upper edge with a disc not visible here, which is located at the height of the upper edge of the spacer strip. The closure bottom forms here a threaded cap, which is screwed onto the threaded connector to a container. So that it can be unscrewed from this if necessary, it is externally provided with ribs 3. The spacer strip 5 forms in the vicinity of the hinge 21 a tab with ribs 1.1, on which it can be taken to tear away.

FIG. 2 shows the closure with the closure cap 2 unfolded. In this state, the closure comes out of the injection mold. The spacer strip 5 is integrally formed on the lower edge of the closure cap 2. On the inside of the cap can be seen a ring 25, which is inverted when closing the cap 2 on the drinking and pouring spout 13 and then encloses it at the top. This drinking and pouring spout 13 is here arranged centrally in a flat disc 7, with which the closure cap 2 is connected via the hinge 21. Outside on this. plane disc 7 latching elements 12 are formed. The disk 7 with the enclosed by her drinking and pouring spout 7 can be pressed axially downwards, after which the latching elements 12 snap on matching snap elements on the closure part 4 and the disc 7 together with the drinking and pouring spout 13 in this lowered position hold or arrest. The drinking and pouring spout 13 has at the upper edge on the outside a bead 10. This is positively enclosed by the ring 25 on the inside of the cap 2, when the cap 2 is pivoted down to the neck. In the clear opening 9 of the drinking and pouring spout 13 is a star-shaped reinforcement 31 molded. If the closure cap 2 is pivoted from the position shown here onto the closure bottom part 4, then the ring 25 snaps over the upper edge of the drinking and pouring spout 13 and holds the cap 2 down. Then the closure is shown as shown in FIG.

Figure 3 shows the closure in this position again, but in a different angle, so you can see the area below the flat disc 7. As can be seen, extends below the disc 7 from the drinking and pouring spout 13 from a deformable wall 8, which forms a kind of vault or dome here, that is, the wall is curved outward and extends obliquely down and is at her lower end connected to the upper edge of the closure part 4. This wall 8 may also form a cone with inwardly curved wall or a bellows. To open the closure, the closure cap 2 is pressed axially downwards in the swung-open state. At the closed closure, as shown in FIG. 1, the spacer strip 5 is first torn away, with the closure cap 2 still closed.

This state of the closure is shown in Figure 4 with reference to a cross section. With a finger or with the hand, the cap 2 is now pressed down. As a result, the drinking and pouring spout 13, with its inner reinforcement 31 and the disk 7 surrounding it, also shifts axially downward, while the wall 8, which is arched in this way, deforms. Finally, engage the latching elements 12 on the outer edge of the disc 7 with associated latching elements 32 at the upper edge of the closure part 4 a. At the same time, the lower, serrated edge of the drinking and pouring spout 13 has pierced with its lancing elements 22 the sealing film, which is attached over the threaded end provided with the closure or glued to the shoulder 30, which on the inside of the closure base 4 is formed. Only now is the cap 2 swung open and thus releases the drinking and pouring spout 13. The sealing film was therefore pierced and opened, without the drinking and pouring spout 13 had to be touched with your fingers!

In Figure 5, the closure is shown in perspective seen from below. At the back of the closure you can see the hinge 21. In the center of the closure can be seen the drinking and pouring spout 13 with the piercing elements 22 at its lower edge. The spout 13 is enclosed from below by the deformable wall 8. This forms here the underside of a vaulted raise. It is also provided with areas 17,18 which form bulges up or down, and facilitate the deformation of the wall 8 during depression of the nozzle 13 by the cap 2. In the example shown, S-shaped ribs 19 are still formed. These cause when depressing the nozzle 13 and deforming the wall 8 that the nozzle 13 is placed during its downward movement in a slight rotation, which facilitates the piercing and cutting a sealing film with the lancing elements 22. In Figure 6 you can see a similar image in a slightly different angle.

FIG. 7 shows the closed closure seen from the rear. You can see the hinge 21, the closed cap 2 and at its lower edge then the spacer strip 5, which acts as a spacer by rising with its lower edge on the lower closure part 4 and prevents the depression of the cap 2 on the closure part 4. For depressing this spacer band 5 must first be removed. For this purpose, it can be taken on the tab with the ribs 11 and be torn off under breakage of the various fine material bridges from the lower edge of the cap 2.

8 shows a cross section through such a closure after the depression of the cap 2. As can be seen, thereby the drinking and pouring spout 13 was depressed and its lower, equipped with lancing elements 22 edge has the sealing film 26, which closed the container neck 23, torn open. The disk 7 latched on the bottom of the closure 4 and now holds the drinking and pouring spout 13 in this position, even if the cap 2 is swung open. The spacer strip 5 is no longer visible because it was previously demolished. The closure bottom is designed as a threaded cap with internal thread 27.

Figure 9 shows a very similar closure, with the only difference that here the closure base is not designed as a threaded cap, but as Aufpresskappe with a circumferential in-lying bead 29, with which it is aufbrellbar to a correspondingly shaped container neck. An existing between the closure and the container edge film can be glued on both sides or welded with induction heat. Figure 10 shows a again similar closure, the closure bottom is formed in a flange 28, with which the closure over the foil-sealed hole of a container, for example, a carton pack is glued or welded. In the figure 11 finally some different types of containers are shown, which can be equipped with such a closure, namely a bottle made of plastic, namely a PET bottle, or such of sheet metal or glass, then a composite cardboard in any form, for example a round or cylindrical composite package or a brick composite package. But it is also suitable for a closed with a plastic lid with sealing foil cardboard cup or for a tube.
