ES2247879B2 - MEANS OF RETAINING THE LANDSCAPE OF AN IRRELLENABLE LID. - Google Patents

Abstract

The present invention relates to a means of retention of the pourer of a non-refillable cap, of the caps which incorporate a valve and possibly means of inhibiting violation or of providing evidence of opening. This means of retention consists of a deformable ring present on an internal step of the cap intended to receive the teeth of the pourer remaining immobilized in the event of turning one with respect to the other.

Description

Means for retaining the landfill of a plug irrellenable.

Object of the invention

The present invention relates to means of retention of a landfill of a non-refillable plug, between plugs incorporating a valve and possibly means antiviolation or opening evidence.

Characterize on the body of this plug the presence of an internal step with a deformable ring intended to receive the teeth of the landfill being immobilized in front of the I turn on each other.

Background of the invention

Irrefillable plugs are known in very various configurations and with diverse technical solutions referred to the valve, the opening evidence, or to fixing means between the cap and the bottle or between the cap and other additional pieces that this one incorporates.

The landfill is the piece through which the liquid and constitutes together with the chassis and a core a piece fundamental in the valve of this type of plugs non-refillable

The landfill is the piece accessible from the exterior since the rest of the pieces are either inside of the valve or, as is the case of the chassis, is protected by the outer cylindrical body or skirt.

The skirt has internal projections verticals that stop at other external projections of the bottle so that the skirt is held in front of the turn Regarding the bottle.

This type of retention is important since the opening of the cap requires the application of a pair or press or for the opening that must be absorbed by the different elements of retention or mutual support.

Considered the fixed skirt with respect to the bottle, the landfill must be fixed either against the bottle or Good against the skirt.

Since the bottle should not be included more supportive highlights, the solution usually considered is the incorporation of retention means between the skirt and the landfill based on the use of teeth in both that immobilize them Regarding relative rotation.

The Spanish Patent ES2113051 is known in the that a landfill is shown on its lower edge teeth that are intended to engage or engage on a plurality of equidistributed teeth located on a step internal cap skirt.

This solution is not optimal since the dump manufacturing procedure requires the use of Molds with side and opposite outlet. This movement of the mold requires that the teeth can only be either in positions corresponding to the joint between molds or in the part intermediate but with orientation parallel to the output of the molds. This restriction makes it impossible to use a number raised teeth and that its orientation, except those that correspond to the four quadrants, do not be radial and therefore grab it with The skirt teeth are not optimal.

The present invention considers a solution of optimal grip for this type of landfill and others that have A greater number of teeth.

Description of the invention

The present invention consists of means of  retention between the main body of the cap and the landfill. He type of cap considered must have a retaining skirt over the bottle; however, the present invention is applicable to stoppers with or without opening evidence such as breakable rings as these modify the configuration out of position of the retention points between the landfill and the plug.

The invention consists in the incorporation of a step between the inner wall of the cap and the skirt, a step which presents a pointed and projected downward projection.

Since the section is reduced and found its pointed section, the material is easily deformable by the pressure of a tooth of the landfill.

During the application of the cap, on the bottle is initially placed the chassis and the valve core closed by the landfill. The latter leaves on the edge of the bottle the perimeter edge with the teeth projected towards above and located adjacent to the wall of the same landfill.

The cap comes under pressure until you highlight them lengths of the skirt retain it in front of the turn. The descent ends when the annular shoulder of the internal step of the stopper rests against the teeth of the landfill deforming and leaving the nailed teeth

Since the fixing process is produced by  The plastic deformation of the ring protrudes, they are all teeth of the landfill those that offer resistance against the turn and of a optimal mode because it is not important that the teeth are not all projected radially to the landfill.

This type of union therefore optimizes mutual retention against the rotation of the plug and the landfill.

Description of the drawings

This descriptive report is complemented, with a set of drawings, illustrative of the preferred example and never Limitations of the invention.

Figure 1 shows an embodiment of the invention consisting of a non-refillable stopper body of which no neither the bottle nor the landfill is shown, including a detail of the annular shoulder section.

Figure 2 is a view of the landfill, including a schematic of the valve core and the bottle on which it is incorporated.

Detailed presentation of an embodiment

Figure 1 represents an embodiment of  the invention in which a non-refillable cap has been chosen without breakable ring, although its presence would not change the invention.

The cap consists of a lower skirt (1) with vertical extensions (1.1) for retention against rotation when they support a projection (4.1) outside the bottle (4). In addition to these vertical extensions presents a ring (1.2) axial retention perimeter.

It is on the bottle (4) where, just as Figure 2 shows, the chassis (5) and core (6) of the valve closed all by the landfill (7).

In turn, on the skirt (1) is the upper body (3) separable at the time of first opening by means of a breakable bridge (3.1) or line of weakening.

Just below the line of weakening (3.1) is find, arranged internally, a step (2) that coincides with the step that defines a perimeter edge (7.1) of the landfill (7).

It is on the perimeter edge (7.1) of the landfill (7) where the teeth (7.1.1) of retention of the body of the cap, and they do it by nailing and deforming a protrusion annular (2.1) located on the step (2) and projected towards down.

In this embodiment, the annular shoulder presents the flank facing the inner wall of the skirt (1) oblique of so that it leaves a hollow or open channel that allows during deformation the material expelled by the tooth (7.1.1) has space and do not prevent the correct entry.

They do not alter the essentiality of this invention variations in materials, shape, size and arrangement of component elements, described in a non-limiting manner, sufficient this one to proceed to its reproduction by an expert.

Claims (3)

1. Retention means of the landfill of an non-refillable stopper, of the non-refillable stoppers that have or not means of opening evidence, characterized in that they consist of the presence of a step (2) between the skirt (1) and the upper body ( 3) of the cap, under the line of weakening (3.1) that separates them, step (2) that has a deformable and projected downward perimeter ring (2.1), with retention by nailing the teeth (7.1.1) of the landfill (7) adjacent to its outer face. 2. Landfill retention means of a non-refillable cap according to claim one characterized in that the deformable internal perimeter ring (2.1) has its pointed section. 3. Landfill retention means of a non-refillable cap according to claim one, characterized in that the deformable internal perimeter ring (2.1) has its internal face facing the internal wall of the oblique skirt (1) giving rise to an open channel.
