Definitions

  • the present disclosure relates to liquid product packaging improvements and more specifically to improvements in liquid product packaging caps with opening plugs.
  • Opening plugs are used in packaging for: food, beverages, soft drinks, juices, but also chemical cleaners, drugs, oils, lubricants and other products. Opening plugs are used to open packaging.
  • Liquid product packaging is made of various plastic materials or metal alloys such as aluminium, iron, tin, bronze, etc.
  • Liquid product packaging remains for a long time exposed to pollutants and germs from the packaging of the product to its consumption by the end user, resulting in an increased risk of user exposure to pollutants and contaminants.
  • the reason why the user may be exposed to pollutants and contaminants from the packaging of liquid products is because it has three key flaws:
  • the metal opening plug enters the interior of the product packaging, polluting and contaminating the liquid content because the outer surface of the liquid product packaging of the metal plug is exposed to pollutants, germs, insect and rodent dirt.
  • the liquid product packaging As the liquid product packaging is leaned at an angle by the user to consume its liquid content, the liquid content flows to the outer walls of the liquid product packaging, resulting in being polluted or contaminated by dirt (dust, soil etc.) or adsorbed pollutants which may have toxic and residual exhaust gases and other air pollutants as well as contaminants such as insect, rodent, cockroach, etc. residues.
  • the metal opening cap is removed from the liquid product packaging, to prevent the metal opening plug from entering into the liquid product packaging, polluting and contaminating the liquid content, but the other drawbacks persist.
  • the drinking straw stops being stable when it rises to the liquid level (due to the buoyancy of the plastic in the liquid content) and is positioned at a large inclination oscillating with respect to the packaging. It takes the user more concentration and more time to put the drinking straw in his/her mouth.
  • a liquid product packaging cap comprises a fixed portion and a metal opening plug attached to the fixed portion.
  • the metal opening plug has 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 and a first part of a male-female type fitting.
  • the fixed portion has 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 is internally secured in the packaging, sterilised and, in use, it prevents the liquid content from being in contact with the external surface of the liquid product packaging.
  • the proposed invention overcomes the aforementioned disadvantages and creates a safe way to remove the liquid content from the packaging without the user being at risk of exposure to polluting and contaminating agents.
  • the user applies force to the traction ring attached to the metal plug through the retaining pin.
  • a portion of the metal plug is bent slightly into the interior of the liquid product packaging to aid in cutting the opening plug off and opening the metal opening plug from the liquid product packaging cap. Due to the distance of the metal plug from the level of the liquid content and because of the dispenser gland that is internally fixed, the metal opening plug does not touch the liquid content. With a second movement by the user, the metal opening plug wraps over the liquid product packaging cap, so that the liquid content is not polluted.
  • the metal opening plug when folded into the packaging cap, is secured on the surface (through the pressure applied by the user) with a male-female type fitting through which the metal opening plug is held on the cap of the liquid product packaging.
  • the metal opening plug after its removal and its opening in the cap of the liquid product packaging has a sharp circumferential edge.
  • a membrane has been placed circumferentially to the opening plug in the liquid product packaging. This membrane is shaped and attached in the packaging and around the opening plug so as to have the tendency to spring out (due to the pre-existing bending stress) and to cover the sharp circumferential edge of the metal opening plug, thereby protecting the user.
  • the dispensing gland which is internally secured in the packaging is sterilised and prevents the liquid content from entering into contact with the cap of the liquid product packaging, which has been in contact with pollutants and contaminants, as it is exposed to the environment.
  • the user by putting his lips only at the sterilised dispensing gland and not on the outer casing of the packaging of the liquid product packaging avoids contact with polluting and contaminating agents.
  • the packaging is discarded for recycling along with the metal opening plug, as the latter is not removed from it. This has the benefit of protecting the environment and the packaging industry, by recycling the packaging of liquid products.
  • the dispensing gland is made of various materials, metal, plastic, silicone, rubber, paper, resin, etc. and any other material that has the property of storing mechanical energy through elastic deformation and that does not affect and is not affected by the liquid content of the liquid product packaging.
  • the dispensing gland is shaped and attached in the packaging so that it has the tendency to spring out once the metal opening plug opens (due to the preexisting bending stress) and to remain in a vertical position (with respect to the liquid product packaging cap packaging).
  • a protection mesh is integrated into or attached to the dispensing gland, which is an integral part of the latter.
  • This protection mesh is embedded or fixed to the dispensing gland, opens together with the gland and when the gland springs out of the packaging, the protection mesh closes the opening in the packaging after it is opened by the user.
  • the protection mesh By adding the protection mesh to the dispensing gland, the entry of an object or insect is prevented since the protection mesh prevents entry of anything larger than its gaps, as does a common protective filter in any other application.

  • Figures 8A to 8H schematically illustrate various states of a liquid product packaging cap, according to a fifth example.
  • the liquid product packaging cap (801 ) comprises a metal opening plug (802), a dispensing gland (803), a sharp circumferential edge guard for the opening plug (804), a packaging cap strengthening rib (805), a frangible line (806) to cut the opening plug, an opening plug strengthening rib (807), a traction ring- opening plug retaining pin (808), a traction ring (809), a folding line (810), to drive the opening plug bending a folding line (81 1 ) to drive the opening plug bending, a male-female type fitting (812), a protection mesh (813), a preselected pre-cut area for the protective mesh (814).
  • Figure 8A shows the liquid product packaging cap (801 ) as produced by the factory and ready for use.
  • Figure 8B shows the first operation phase by the user.
  • the user applies force to the traction ring (809) attached to the metal plug (802) through the traction ring-opening plug retaining pin (808).
  • a portion of the metal plug (802) is bent slightly into the primary folding line to drive the opening plug bending (810) to the interior of the liquid product packaging to aid in cutting the opening plug (807) off and open the metal opening plug (802) from the liquid product packaging cap (801 ).
  • Figure 8C shows the second operation phase by the user.
  • the user pulls the traction ring (809) and the metal opening cap (802) is cut off circumferentially over the entire length of the frangible line (806) of the opening plug and remains attached to the folding line (81 1 ) to drive the opening plug bending.
  • the dispensing gland (803) is ready to be released and spring out from the liquid product packaging cap (801 ).
  • Figure 8D shows the interval between the second and third operation phases by the user. Used for understanding purposes. The dispensing gland (803) is ready to be released and spring out from the liquid product packaging cap (801 ).
  • Figure 8E shows the interval between the second and third operation phases by the user. Used for understanding purposes. Cutting has been completed across the frangible line (806) of the opening plug. The user has completed pulling the traction ring (809) and is removing his finger from the traction ring (809). The dispensing gland (803) is fully released and has followed a 90- degree trajectory. Below the dispensing gland (803) a protection mesh (814) is integrated, forming an integral part of the dispensing gland (803). The protection mesh (814) is drawn by the dispensing gland (803) and moves with it. The protection mesh (814) in its final position fits fully into the opening in the packaging after it is opened by the user and allows the flow of liquid products out of the packaging, while preventing the entry of insects or objects into the packaging.
  • Figure 8F shows the third operation phase by the user.
  • the user applies pressure to the metal opening plug (802) thereby eliminating the elastic recovery tendencies of both the primary folding line to drive the opening plug bending (810) and the folding line (81 1 ) to drive the opening plug bending, creating a plastic deformation on the metal opening plug (802) resulting in both bending lines (810) and (81 1 ) remaining parallel to the liquid product packaging cap (801 ).
  • Figure 8G shows that at the same time as the above process, the metal opening plug is held onto the cap of the liquid product packaging (through the pressure applied by the user) using a male/female type accessory (812).
  • the dispensing gland (803) is fully released and has followed a 90-degree trajectory and the user can consume the contents of the packaging in a safe manner.
  • Figure 8H shows the preselected pre-cut area for the protective mesh (814) which has been pierced and the user has placed the drinking straw.
  • Figure 9 shows in detail an additional protection mesh support accessory
  • Figure 10 shows in detail the additional dispensing gland support accessory (1016).
  • the protection mesh apart from the gaps it has to prevent insects or objects from entering, has a pre-selected pre-cut area to allow the user to insert a standard sized drinking straw into the packaging.
  • the user applies the drinking straw to the protection mesh (813) and the latter is cut at the pre-cut points (which are preselected for this purpose by design), the drinking straw passes through the protection mesh (813) and enters in the packaging.
  • the preselected pre-cut area for the protective mesh (814) with the pre-cut has a slightly smaller diameter than the drinking straw, which when inserted into the former, is stabilized by the clamping fit.
  • the clamping fit is necessary so that the drinking straw does not rise (due to the buoyancy of the plastic in the liquid content) and make it difficult for the user to place the drinking straw in his mouth.
  • an additional dispensing gland support accessory (1016) is incorporated or secured on the back of the dispensing gland (803) to assist in the dispensing gland opening (803).
  • the additional dispensing gland support accessory (1016) is made of metal or plastic, and any other material having sufficient elastic recovery, with which it draws and ultimately helps the dispensing gland (803) to exit the packaging.
  • an additional protection mesh support accessory (915) has been incorporated to assist the opening of the protection mesh (813) and therefore, the dispensing gland drawn by the protection mesh.
  • the additional protection mesh support accessory (915) is made of metal or plastic or any other material that has an elastic recovery.
  • the additional protection mesh support accessory (915) assists the protective mesh (813) to cover the hole opening and hence the dispensing gland to be drawn out of the packaging.
  • the additional protection mesh support accessory (915) exerts a force on the protection mesh (813) and the protection mesh (813) exerts force in turn to the dispensing gland draw out of the packaging.
