Definitions

  • the present invention relates to a dosing cap configured so as to result in lower manufacture costs and generate less environmental impact during the process of manufacturing it and after disposal thereof.
  • the commercial segment of packages comprises determined flasks and bottles provided with dosing caps.
  • a dosing cap can be useful in sealing the package of any type of liquid or pasty product, such as foods (for example, ketchup), cosmetics (for example, shampoo), cleaning products (for example, clothes softeners), among others.
  • foods for example, ketchup
  • cosmetics for example, shampoo
  • cleaning products for example, clothes softeners
  • a dosing cap occurs most frequently with those products that require the control of liquid being dispensed.
  • the user does not always wish to pour the entire contents of the bottle of mustard directly onto his food or hot-dog.
  • the user of a product such as mustard or ketchup needs a type of packaging that enables him to control the contents poured into his food.
  • a dosing cap functions on the basis of the following principle:
  • a silicone valve 3' - also referred to as a diaphragm - arranged inwardly of the central cap orifice is opened due from the positive pressure that forms from within the flask or bottle.
  • This valve is made up by a flexible membrane provided by a tear centrally arranged with respect to its top face.
  • the pressure that forms inside the flask or bottle when it is squeezed is sufficient to increase the opening of this tear, thus enabling the evacuation of the flask or bottle content out of the package.
  • the silicone valve 3' closes, cutting the flow of fluid poured out of the flask or bottle (hence, the name "dosing cap").
  • a prior-art dosing cap 5' consists of the combination of three independent parts, namely:
  • Each of these elements comprises a mold, a constitution material (resin) and a different manufacture process.
  • the cap body 1' is constituted by a first type of resin (for example, PP or PAD) and may be of the flip-top type, with either a threadable sealing or fitting sealing).
  • a first type of resin for example, PP or PAD
  • PAD polystyrene-maleic anhydride
  • FIG. 1 of this specification specifically, a conventional flip-top cap is illustrated.
  • the process of manufacturing the cap 1' body occurs by thermoplastic injection of the first type of resin into a mold cavity that contains the external profile of the cap.
  • the silicone valve 3' is constituted by silicone (which constitutes a second type of resin).
  • This valve has an "x"-shaped cut 4' arranged centrally in its structure. Its manufacturing process involves two different steps, namely: a first step for injecting silicone into a disc-shaped small mold, and a second step for making the X-shaped cut 4'. It should be noted that each of these steps is carried out by means of independent machines that operate at different times (that is, the operation for making the X-shaped cut 4' evidently can only be carried out after the silicone-injecting step).
  • the holding ring 2' is an intermediate piece placed between the silicone valve 3' and the cap body 1'. Its usefulness is due to the fact that the material that constitutes the silicone valve 3' is incompatible with the material that constitutes the cap body 1'. Thus, the holding ring 2' is necessarily made from a material whose molecular constitution enables it to be secured easily to both the material of the cap body 1' (usually, PP or PAD) and to the material of the silicone valve 3'. Since the holding ring 2' is constituted by a material other than those of the silicone valve 3' and of the cap body 1', it should necessarily be manufactured by a third thermoplastic injection process.
  • the holding ring 2' may be manufactured in a determined country, while the other parts are manufactured in a second country, and so on. This decentralization of operations naturally increases the costs with logistics of manufacture of the prior-art dosing cap 5', thus raising the production costs of this part.
  • this prior art dosing cap 5' should be replaced by a more economical and more ecological alternative.
  • This new technology should lower the manufacture costs and the environmental impact of this cap, without, however, impairing its efficiency in operation, chiefly as far as the dosing or "drop-cutting" function is concerned, a characteristic essential to its functioning.
  • the present invention has the objective of providing a dosing cap that has less environmental impact and exhibits lower manufacture cost.
  • the present invention has also the objective of providing a flexible flask or bottle package having a dosing cap as described above.
  • a dosing cap for flexible flask or bottle packages which is configured into a single piece comprising a restrictor provided with means configured to enable interruption of the product flow through its structure.
  • the present invention consists of a dosing cap 1, injected into a single piece (see figures 2, 3 , 4 and 5 ).
  • the dosing cap 1 of the present invention can be injected into a single piece because it comprises elements constituted by the same resin of the cap body 1', which exhibit the same function of the valve-ring assembly 6' of the prior-art caps.
  • the dosing cap 1 of the present invention since the dosing cap 1 of the present invention is injected into a single piece, it reduces drastically the costs with production and the impact caused on the environment (before and after disposal thereof), without diminishing the efficiency of the function performed by the cap. In other words, although it does not comprise a silicone valve 3', the dosing cap 1 of the present invention continues to be capable of cutting the flow of the product poured out of the flask or bottle, according to the interruption of the squeezing of the container.
  • the element of the dosing cap 1 that makes it capable of cutting the flow of material squeezed out of the flask or bottle is the restrictor 2, clearly represented by figures 4 , 6 and 7 .
  • the restrictor 2 can be defined as being any element provided with at least one restriction bore 6, which is arranged preferably at the same place where the silicone cap 3' of the prior-art dosing caps 5' is arranged.
  • restriction bore 6 The function of the restriction bore 6, as the name itself indicates, is to restrict - that is, "to hamper or make difficult” - the passage of the fluid stored in the package (not shown in the figures) while the flask or bottle is being squeezed.
  • the cross-sectional area of the restriction bore 6 should vary according to the viscosity of the fluid stored in the package. So, the more viscous the fluid the larger the cross-sectional area of this restriction bore 6 will be, since it is known that the higher the viscosity of a fluid the lower its flowing velocity through a determined bore.
  • This cross-sectional area should be small enough to prevent the fluid from flowing through these bores under the exclusive action of the gravitational force on the fluid mass (a situation in which the flask is positioned "upside-down", without squeezing), but should be large enough for enabling the fluid to flow when the flask is squeezed.
  • the model of dosing cap 1 disclosed in the figures of this specification is especially adapted for application to ketchup and mustard containing flasks or bottles.
  • a restrictor 2 having four restriction bores 6 arranged radially, each having about 1 mm 2 cross-sectional area, is sufficient to provide good dosing or "drop-cutting" for this type of fluid.
  • the restriction bores 6 should have a substantially larger cross-sectional area, of about 4 mm 2 for each restriction bore 6.
  • a fluid having lower viscosity such as liquid soap
  • a dosing cap 1 provided with a restrictor 2 having restriction bores 6 having a much smaller cross-sectional area, for example with a bore opening of 0.5 mm 2 .
  • restriction bores 6 varies depending on the viscosity of the fluid stored in the package
  • number of restriction bores 6 of the restrictor 2 should vary according to the flow rate and the thickness of the liquid flow that is to be achieved for the use of a determined product.
  • the dosing cap 1 of the present invention may comprise other elements instead of the restrictor 2, which are configured to carry out the same restriction of the product flow.
  • Such elements may be, for instance, flaps or restriction tubes, restriction protrusions or any other elements comprised by the matrix itself of the dosing cap that are configured for obstructing partially the passage of the fluid contained in a package out of the flask or bottle.
  • the present invention can be defined as a dosing cap 1 configured for enabling one to cut any type of fluid, this dosing cap 1 being configured into a single piece.
  • the dosing cap 1 configured as a single piece means that this piece is produced by a single thermoplastic injection process.
  • the use of a single thermoplastic injection process brings about two direct benefits to the dosing cap 1.
  • the first benefit is the decrease in costs with the production of the cap. This can contribute to increase the profit margin of the producer of the cap; the profit of the intermediate consumer (for example, a company from the foods industry or a manufacturer of cleaning products); and still to decrease the cost of the final product, for example, the price charged for a flask or bottle of mustard exposed on a supermarket shelf.
  • the second benefit is the ecological appeal of the dosing cap 1 of the present invention. Since it is manufactured by a single thermoplastic injection operation, the manufacture of this cap requires much less energy than the process of manufacturing conventional caps. Since one employs only resin in its constitution (as opposed to the three different types of polymeric resins employed ion the constitution of the prior-art dosing cap), this dosing cap 1 can be recycled quite easily.
  • the flip-top closure of the dosing cap 1 As a characteristic complementary to the invention, one can cite, for instance, the flip-top closure of the dosing cap 1.
  • This flip-top system is quite known in the art and consists in providing a top covering 3 that is associated to the rest of the dosing cap 1 through small polymeric membranes 7 constituted by the same resin that forms the cap.
  • the flip-top closure is a mere detail complementary to the present invention, which could be replaced, for instance, by a threadable or snap-fit-type top covering 3, without this replacement altering the inventive concept defined in this specification.
  • a second characteristic complementary to the present invention refers to the double sealing provided by the sealing rings 4, 5, arranged on the inner face of the top covering 3.
  • Such a sealing could be replaced by any other form of sealing, as long as it is functional.
  • the dosing-cap 1 of the present invention might comprise, for instance, only one external sealing ring 4 or only one internal sealing ring 5.
