Definitions

  • the present invention relates to a package comprising a container and a measuring cup adapted to serve as a closure.
  • the improvement of the present invention achieves a consistent saving in the manufacturing material, maintaining all the common characteristics of similar packaging, such as, for example, a liquid tight seal and self draining properties.
  • Packages comprising a container and dosing cap are well known in the prior art.
  • the container is able to contain liquid or granular substances.
  • the dosing cap is a measuring cup adapted also to serve as a closing system. With the help of said dosing cap a certain contained substance is dosed and the container is closed in a detachable manner. Lightweighted packages are desirable, because of the low weight and reduced cost in materials required for their manufacture and the reduced cost related to the disposal. It is an object of the present invention to propose a package which achieves a consistent material saving in the manufacture of said package.
  • a problem associated with these packages is the spillage from said dosing cap onto the container, when it is applied again after use on the container, which can cause contamination of the closure systems, such as threads, with the contained product, as well as dripping along the container, making the closure and container messy, very slippery and thus difficult to handle.
  • EP-B-0 369 560 or WO 83/03085 describes an assembly, in which the measuring cup, threaded on the outside of said neck of the container, presents a skirt extending into the pouring spout body, which protects the threads of said measuring cup.
  • EP-A-0 417 954 in which the drain back trough is part of the container's body. Said trough has to be formed through an inversion of part of the neck of the container after the blow-molding process.
  • FR-1 508 355 shows a package according to the preamble of claim 1, in US-4 696 416 and US-4 981 239.
  • the dosing cap has a fastening means formed on its external surface, adapted to be sealed tightly to the interior surface of a collar secured to the orifice of the container. This means that no extra skirt is needed in this case to protect the threads of said dosing cap, although an intermediate piece, which joins the container and the dosing cap, is still required in US-4 696 416 and US-4 981 239.
  • the present invention reduces the necessary packaging material by inserting the dosing cap inside the neck of the container directly, as will be described further on.
  • the amount of packaging material or weight of the dosing cap is primarily determined by the mass density of the manufacturing material and the thickness of the wall of said dosing cap.
  • the thickness determines the final resistance and stability properties of said cap. The resistance and the stability are important features of a reusable dosing cap, since it has to be gripped many times in order to open the container, especially considering that most of the commercially available containers are refillable.
  • the present invention is a package comprising a container and a dosing cap, said cap comprising a top and a circumferential wall.
  • the wall of said cap has two different thicknesses, the thinner walled part of said cap fitting into the neck of said container, to achieve a liquid tight seal, according to claim 1.
  • Figure 1 illustrates the top end of the closed package in the preferred embodiment of the present invention, suitable for holding liquid or granular substances and the like.
  • the container (10) is provided with a handle (not shown), integrally molded therewith, to provide a gripping means to facilitate holding and carrying the container (10) and dispensing its contents.
  • the container (10) has a removably attached closure (20) to prevent inadverted spillage or loss of freshness of the contents of the container (10).
  • the closure (20) may also be used as a measuring cup, to ensure the desired quantity of liquids is dispensed.
  • the closure (20) is attached directly into the neck (12) of the container (10) in a liquid tight manner.
  • Figure 2 is a cross sectional side view of Figure 1, showing the different thicknesses of the circumferential wall of said dosing cap (20).
  • the thickness of said wall is defined to be the minimal distance between the inner and the outer surface of the wall.
  • the thinner walled part (26) begins right under the external ridge (22). Said thinner part (26) fits into the neck (12) of container (10) in its closed position. Since said thinner part (26) of cap (20) is entirely protected by the neck (12) of container (10), said part (26) can be of a minor resistance and stability than the rest of the dosing cap (20). Since only a minor resistance and stability conditions are necessary, as explained before, part (26) can be thinner walled than the rest.
  • the thicker walled part (28) begins from the external ridge (22) upwards. This part (28) of said dosing cap (20) remains outside the neck (12). This part (28) needs to maintain a certain stability and resistance, since said part (28) has to be gripped firmly, in order to disconnect said dosing cap (20) from the neck (12) of container (10). This operation has to be accomplished many times.
  • the spillage free feature of the package of the present invention is another advantage, which is a direct consequence of the partial insertion of the dosing cap (20) into the neck (12) of container (10). It is evident that the rest of the dosed substance flows or falls automatically back into the container. This leads to the unnecessity of any drain back trough or other feature to convey the rest of any dosed substance back into the container. Not needing any particular drain back facility, as said before, also diminishes the amount of packaging material necessary for the package. This results in a significant material saving versus the packages of the prior art.
  • the dosing cap (20) may have two inclined features : the external ridge (22) and the groove (24).
  • the groove (24) on the outer surface of part (26) of the dosing cap (20) fits exactly onto the identically sloped internal ridge (14).
  • This internal ridge (14) is made on the inner surface of the neck (12) of container (10) and it has the identical shape of the groove (24), in order to get a liquid tight seal.
  • the dosing cap (30) can also have two external ridges (22) and (32).
  • the ridge (32) fits now into the groove (34) on the inner surface of the neck (12).
  • the number and the shape of grooves (24) or ridges (32) and the corresponding internal ridges (14) and grooves (34) can be varied by any person skilled in the art.
  • the neck (12) of the container (10) not only contributes to the closure system, but it also serves as the pouring spout of the container of the present invention.
  • the fitting of the cap (20) into the neck (12) is only possible, if the lip (29) of the neck (12) is identically inclined as the external ridge (22) of cap (20).
  • the inclination is defined by an angle ⁇ .
  • This angle ⁇ is measured from the plane defined by the supporting basis of the container (10) in its upright position to a line parallel to the lip of the neck (12) or external ridge (22). Therefore the angle ⁇ has to be always equal for both the external ridge (22) and the lip (29) of neck (12), in order to obtain a liquid tight seal.
  • Figure 4 schematically shows certain features which further improves the liquid tightness applicable to all embodiments.
  • the new feature in respect to Figure 2 is the ridge (8) between the neck (12) and collar (9) of the container (10).
  • Said ridge (8) forms all around inside the neck (12) an area (7).
  • Said area (7) is sloped in Figure 4, but it can also be flat.
  • the lip (27) of the dosing cap (90) has the same slope as the area (7).
  • the lip (27) of the dosing cap (90) coming in direct contact with area (7) assures an improved liquid tightness of dosing cap (90).
  • FIG 9. Another embodiment of the present invention is shown in Figure 9. It is similar to Figure 2 with the only difference that the lip (27) of the dosing cap (80) is also inclined with an angle ⁇ . This angle ⁇ is measured from the plane defined by the supporting basis of the container (10) in its upright position to a line parallel to the lip of the dosing cap (80) The inclination of lip (27) helps the pouring out of the dosed substance.
  • the different thickness of the circumferential wall of the dosing cap is schematically illustrated.
  • the thickness of the walls of the dosing cap of the present invention may be up to 1.2 mm, preferably up to 0.6 mm, and most preferably from 0.1 mm to 0.3 mm especially for the thinner walled part of said cap.
  • All the angles ⁇ , ⁇ and ⁇ have values, which can be chosen by any person skilled in the art for any necessary specific requirement. Preferably said values are from 0 radians to 5 ⁇ /12 radians, more preferably from ⁇ /12 radians to ⁇ /3 radians.
  • plastics are generally thermoplastics, such as PolyEthylene (PE), PolyEthylene Terephthalate (PET), PolyPropylene (PP), PolyVinyl Chloride (PVC), and any other, less common polymers, like PolyStyrene, PolyCarbonate and Ploymethane. These type of plastics is completely recyclable. It is possible to have material savings up to 80 % compared to current self draining caps.
  • PE PolyEthylene
  • PET PolyEthylene Terephthalate
  • PP PolyPropylene
  • PVC PolyVinyl Chloride
  • PVC PolyVinyl Chloride
  • All the dosing caps shown in Figures 1 to 9 present on their outer and/or inner surface of the wall of said caps dosing lines (80). Said lines (80) help to dose precisely the contained substance out of the container (10). These lines (80) can be easily varied in number, depending from the specific uses of the contained substances.
  • the pouring spout of the container and the lip of said dosing cap for all embodiments are made anti-drip in order to avoid unnecessary product spillage. Furthermore, a pilfer proof ring, tape, shrink sleeve or the like to avoid cap loosening during transportation and distribution can be added.
  • the possible contained substances are all those ones, which need to be dosed for a specific use. For example, this happens very often in the laundry and household products, such as liquid or granular detergents, liquid softeners, household cleaners and bleaches.
