Description

Cap with security seal for containers plastics

Object of the invention

The present invention relates to a plug used as a means of opening and closing plastic containers.

It is an object of the invention that the cap incorporates sealing means complementary to the sealing means conventionally used, in order to ensure airtightness of the cap to guarantee its inviolability.

Background of the invention

The use of plastic containers is known designed to house sauces such as ketchup, mayonnaise and others, comprising a plastic container and a cap adaptable to said container that is constituted by a body equipped with a pouring tower and a flip top that shows in its inner face a sealing neck that engages on the pouring tower closing the container.

The container can have a seal consisting of a sheet that closes its mouth, which should break to facilitate the output of the product contained in your interior, which leaves the vessel through the tower of poured after folding the lid, dump the container down and squeeze it with your hands.

In this situation where it has already been unsealed the container, its closure is established so general by means of the lid that folds towards the container until that the sealing neck engages in the pouring tower preventing the exit of the product.

This type of seal available to some packaging, consisting of the incorporation of the sheet on the mouth of the container, it has shown insufficient since It is easily breakable.

Other plastic containers have a nozzle swivel mounted around a central body partially Conical as outlet means of the sauce contained inside of the container, nozzle that must be turned to facilitate the passage of product between the body and the nozzle outwards. The nozzle is immobilized in the sealing situation of the  container by means of a hoop that surrounds it by its base and that joins to the nozzle by means of tear strips. When it is intended opening the container turns the nozzle breaking the strips, which determines an indicative signal of opening of the container, moment to from which the nozzle can rotate freely.

This type of seal is set for a particular packaging design, however it is not applicable for containers of the type that are configured by means of a container with a lid with a flip lid.

In other packages the seal is established in the outlet nozzle, which is covered by a laminar body of the same plastic material that forms the cap, which should be cut to give free way to the output of product contained in its interior.

Other containers lack a seal or contain a simple plastic wrap that must be broken to be able to articulate the lid and access inside.

Description of the invention

The cap for plastic containers that constitutes the object of this invention stands out mainly because it incorporates a seal that guarantees the inviolability of the container, which It is integrated between the lid and the cap body, as well as It is easily and conveniently accessible for your unlinking the container

The cap is the type of those with a adjustable body in the container in which a tower of final discharge into a nozzle through which the product comes out contained in the container that is closed by a neck definite seal inside the flip top that fits pressure on it by sealing the container.

The cover sealing means consist of the incorporation of an angle configuration tab, preferably triangular prismatic, at the edge of the lid and a seal or flap associated with the upper perimeter edge of the body of the cap, which has an internal recess in its rear face in which the anchoring of the tab is established ensuring the sealed container.

The flap is located in disposition front integrated into corresponding recesses defined in the edge of the body of the cap and in the edge of the lid, and is linked to the body preferably by means of edges defined between a lower sector and a higher sector of the flap.

By inserting a finger through the lower recess of the body comes in contact with the flap on which you can exert pressure upwards by slightly lowering it until detach it from the cap body, releasing the flap of the cover tab where it was anchored by unsealing So the container. In this way the lid is detached from of the body of the cap and the lid can be folded down freely.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to an example preferred practical implementation of it, is accompanied as integral part of that description, a set of drawings where with an illustrative and non-limiting nature, what has been represented next:

Figure 1.- Shows a sectional view of the cap in the situation in which it is sealed with the flap of the body anchored in the tab of the lid.

Figure 2.- Shows a front view of the cap closed.

Figure 3.- Shows a perspective view of the cap open once unsealed after tearing off the flap.

Figure 4.- Shows a perspective view of the flap.

Preferred Embodiment of the Invention

With reference to the figures a mode is described of preferred embodiment of the cap for plastic containers.

As can be seen in figures 1 or 3, the stopper is of the type that are constituted by means of a body (1) adaptable to the container, equipped with a pouring tower (2), and a lid (3) articulated with respect to the body (1) that has a neck shutter (4) that fits over the pouring tower (2) in the closing position

From this basic structure the plug It stands out mainly because the body (1) is endowed with a vertical flap (5) or linked seal, by means of edges (6) defined on its anterior face, to an upper perimeter edge of the body (1), on whose front face it is also found defined a recess (9) that anchors in a tab (10) that is prolongs from the edge of the cover (3) setting the sealing of the cover (3).

The body (1) has a recess (8) in which the lower sector of the vertical flap (5) and the cover (2) are housed It also has a recess (7) defined in its edge, in which tab (10) is located.

It is contemplated that the tab (10) shows a triangular prismatic configuration constituting its free edge the crimping means in the recess (9) of the vertical flap (5).

Claims (3)

1. Cap with safety seal for plastic containers, of the type that are constituted by means of, a body (1) adaptable to the container, which is equipped with a pouring tower (2), and an articulated lid (3) with respect to the body (1) which has a sealing neck (4) that engages on the pouring tower (2) in the closed position, characterized in that the body (1) is provided with a linked vertical flap (5), by means of edges (6) defined in its anterior face, to an upper perimeter edge of the body (1), in whose anterior face a recess (9) is also defined, which anchors in a flange (10) that extends from the edge of the cover (3) establishing the sealing of the cover (3). 2. Cap with safety seal for plastic containers according to claim 1 characterized in that the body (1) has a recess (7) in which the lower sector of the vertical flap (5) is housed and the lid (2) has a recess (8) defined in its edge, in which the tab (10) is located. 3. Cap with safety seal for plastic containers according to claim 1 characterized in that the flange (10) shows a triangular prismatic configuration constituting its free edge the means of crimping in the recess (9) of the upper sector of the vertical flap (5).
