Abstract

Liquid product packaging caps with opening plugs are disclosed. The proposed caps comprise dispensing glands and protection meshes attached to the liquid product packaging caps. In examples, when opening, the opening plugs do not touch the liquid content and fold over the liquid product packaging caps, rather than inside them, while at the same time sharp circumferential edge guards prevent users from touching the sharp circumferential edges of the metal plugs. The dispensing glands are released and prevent the liquid from touching potentially contaminated caps of the liquid product packaging which may have been in contact with polluting and contaminating agents. Protection meshes are fitted or secured to dispensing glands which close the packaging holes after they are opened. The protection meshes, apart from the gaps also prevent insects or objects from entering, have pre-selected pre-cut areas to allow users to insert drinking straws into the packaging.

Claims

1. Liquid product packaging cap comprising a fixed portion and a metal opening plug attached to the fixed portion, the metal opening plug having a sharp circumferential edge guard, a strengthening rib, a traction ring-opening plug retaining pin, a traction ring, attached to the retaining pin, a primary folding line to drive an opening plug bending a first part of a male-female type fitting;

the fixed portion having a packaging cap strengthening rib, a frangible line, partially encircling the metal opening plug, a folding line to drive an opening plug folding, a second part of the male-female type fitting, and a dispensing gland that is releasable from inside the liquid product packaging of the product by opening the metal opening plug, the dispensing gland being internally secured in the packaging, sterilised and, in use, preventing the liquid content from being in contact with the external surface of the liquid product packaging.

2. A product packaging cap according to claim 1, wherein when the user applies force to the traction ring attached to the metal opening plug by means of the traction ring-opening plug retaining pin, a portion of the metal plug is bent slightly towards the inside of the liquid product packaging to help the frangible line to break, detach and open the metal opening plug from the liquid product packaging cap, wherein the distance of the metal opening plug from the liquid level is such that due to the dispensing gland attached inside, the metal opening plug does not enter into contact with the liquid content of the liquid product packaging and the user, with a second move, folds the metal opening plug onto an external surface of the liquid product packaging cap rather than inside it.

3. A product packaging cap according to claim 1, wherein the sharp circumferential edge guard for the opening plug, is a membrane formed and fixed internally in the packaging around the opening plug, under tension and once opened, the metal opening plug is configured to spring out due to the pre-existing bending stress and overlap the sharp circumferential edge of the opening plug, thereby protecting the user.

4. A product packaging cap according to claim 1, wherein the metal opening plug, when folded over its outer surface through the pressure applied by the user, is configured to be secured on the surface with the male-female type fitting through which the metal opening plug is held on the cap of the liquid product packaging.

5. A product packaging cap according to claim 1, wherein the traction ring is articulated and consists of two parts, one of which is fixed to the opening plug by means of a retaining loop of the traction ring of the opening plug, is freely movable with respect to the opening plug after the initial cut off and opening of the metal opening plug from the surface of the liquid product packaging cap, while the metal opening plug is configured to not enter in contact with the content of the liquid product packaging and the user, with a second move, folds the metal opening plug onto the liquid product packaging cap, rather than inside it and by applying pressure on the opening plug, the user neutralises the elastic recovery tendencies of the folding line to drive the opening plug bending, to create a plastic deformation in the metal opening plug so that the opening plug to secure on the fixed portion and remain parallel to the liquid product packaging cap.

6. A product packaging cap according to claim 1 characterised by the fact that a storage cavity of the traction ring is formed in the fixed portion of the liquid product packaging cap, wherein the traction ring is articulated and consists of two parts, one of which to remain fixed to the opening plug by means of the traction ring-opening plug retaining pin after the initial cut off and opening of the metal opening plug from the surface of the liquid product packaging cap, while the metal opening plug does not enter in contact with the content of the liquid product packaging and the user, with a second move, to fold the metal opening plug onto the liquid product packaging cap, rather than inside it and by applying pressure on the opening plug, the user to neutralise the elastic recovery tendencies of the folding line to drive the opening plug bending, create a plastic deformation in the metal opening plug and the opening plug to remain parallel to the liquid product packaging cap, while the traction ring to be placed inside the storage cavity.

7. A liquid product packaging cap, comprising:

a fixed portion and a metal opening plug attached to the fixed portion,

the metal opening plug having;

a sharp circumferential edge guard for the opening plug, an opening plug strengthening rib,

a traction ring-opening plug retaining pin,

a traction ring,

a primary folding line to drive an opening plug bending, a first part of a male-female type fitting,

the fixed portion having;

a packaging cap strengthening rib,

a frangible line to cut the opening plug,

a dispensing gland,

a folding line to drive an opening plug bending, a second part of the male-female type fitting, wherein the fixed portion further comprises a preselected pre-cut area for a protective mesh located under the dispensing gland that is released from inside the liquid product packaging of the product by opening the metal opening plug, configured to be drawn by the dispensing gland and move along with it to a final position fully fitting into the opening and allowing the flow of liquid products from the packaging, while preventing the entry of insects or objects into the packaging.

8. A product packaging cap according to claim 7, wherein the protection mesh comprises a preselected pre-cut area for the protective mesh configured to receive a standard sized drinking straw, to pass through the protection mesh and enter inside the packaging.

9. A product packaging cap according to claim 8, wherein the preselected pre-cut area for the protective mesh has a diameter smaller than the drinking straw which is configured to stabilize the drinking straw by the clamping fit when the drinking straw enters the mesh.

10. A product packaging cap according to claim 9, wherein the dispensing gland comprises an additional support accessory incorporated or secured on the back of the dispensing gland to assist the gland opening through its material.

11. A product packaging cap according to claim 10, wherein the additional support accessory is made of metal or plastic and any other material with elastic recovery, configured to draw the dispensing gland out of the packaging.

12. A product packaging cap according to claim 7, wherein the protection mesh comprises an additional protection mesh support accessory incorporated to assist the opening of the protection mesh and therefore, the dispensing gland to be drawn by the protection mesh.

13. A product packaging cap according to claim 12, wherein the additional protection mesh support accessory is made of metal or plastic or other material having elastic recovery.

14. A product packaging cap according to claim 13, wherein the traction ring is configured in its final position to be parallel to the fixed portion and abut the liquid product packaging via the male-female type fitting.
