Definitions

  • the present invention relates to an improved cap for an applicator, in particular a bristle applicator, as well as to an assembly comprising the cap and optionally a metering device and/or a button and/or a sachet.
  • Caps for applicators are known from the disclosure of DE202014104781U1 (DE'781), which describes a closure (or a cap) for a bristle applicator that is economical and accurate for application of a cosmetic and/or pharmaceutical substance while maintaining hygienic conditions.
  • this benefit was achieved by providing the neck portion of the applicator with a tapered outer shape or form of the closure of the closure cap, which is designed to center the closure cap before its projection reaches the mouth begins to penetrate into the bristles.
  • caps have an inlet, a base having a connection portion embodied for connecting the cap to the applicator and/or a container, and a head configured to receive an application part of the applicator within the head, and a projection formed at a top part of the cap, the top part being formed at an opposite end to the inlet and the projection being configured to cooperate with an outlet of the applicator, for example, by sealing the outlet.
  • a cap having a head that has at least one of a substantially cylindrical or conical inner and/or outer shape and a connection portion with a substantially round inner and/or outer shape, a substantially oval and square inner and/or outer shape.
  • This special geometry guides the bristles such that they are centrally aligned before they reach a projection of the cap.
  • the geometry results in the combined benefits of closing the applicator system tightly with the help of the projection and providing a safe guidance to the delicate bristles during closing.
  • connection portion has a substantially round inner and outer shape and is preferably combined with a head that has at least one of a substantially conical outer shape and a conical inner shape, alternatively combined with a head that has at least one of a substantially conical outer shape and a cylindrical inner shape, a head that has at least one of a substantially cylindrical outer shape and a conical inner shape, or a head that has at least one of a substantially cylindrical outer shape and a cylindrical inner shape.
  • the head that has at least one of a substantially conical outer shape and a cylindrical inner shape and the connection portion has a substantially oval inner and outer shape.
  • the cap comprises an alignment portion and a fitting portion.
  • the alignment portion present as part of the head of the cap, aligns the applicator, particularly the bristles of the applicator, substantially in parallel to a longitudinal axis of the cap.
  • the alignment portion is preferably cylindrical in shape and/or has a length that is about 20% to about 40% of the length of the head. This geometry and length facilitates that the bristles are centered before they reach the projection so that the projection safely passes through the bristles and seals the applicator without damaging the bristles.
  • the alignment portion guides the applicator to ensure the precise centering of the applicator bristles. In the absence of a good guidance, the delicate bristles may get damaged or fall off due to frequent contact with the different parts of the cap. Also, if not centered precisely, the projection of the cap may destroy the fine bristles permanently, rendering the applicator useless.
  • the fitting portion also present as part of the head of the cap, allows the applicator to be detachably fitted inside the cap, such that the cap can house the applicator without letting it fall off.
  • the applicator can be first fitted inside the cap, and then this combined assembly of cap and applicator can be attached to the container. This combined assembly can be useful especially in cases when the applicator needs to be replaced after single use. Hence, the user could replace this combined unit of cap and applicator on the container after every use. This aspect is particularly critical when the applicator should not be exposed to the environment before use, for example, to maintain its sterility.
  • the fitting portion comprises at least one change in inner radius of the head.
  • there is a reduction of the inner radius of the head preferably by means of one or more protrusions, preferably ridges, or a conical geometry or a change from a larger cylindrical diameter to a smaller cylindrical diameter.
  • the cap is for single use applications while in another embodiment the cap is suitable for reusable applications.
  • the cap of the present invention can be made of metal, glass or plastic.
  • the most prefered material would be plastic as it has many advantages over the other materials, such as being light, inexpensive, easy to mould, and long lasting.
  • the cap is made of a thermoplastic, particularly polypropylene (PP).
  • PP polypropylene
  • the cap is made of silicone; and/or a thermosetting resin.
  • connection portion may be a threaded, bayonet, snap-fit or a snap-on connection. These mechanisms for connection have been found to be best suited for connecting the two parts detachably.
  • the connection portion connects the cap to the applicator and/or the container detachably.
  • the cap of the present invention has a projection at the top of the cap.
  • the projection preferably extends at least substantially parallel to a longitudinal axis of the cap, wherein the longitudinal axis of the cap extends through the base and the head, and a central axis of the head is arranged parallel to the longitudinal axis of the cap.
  • a parallel projection therefore minimizes any damage the applicator part.
  • the projection may be inclined accordingly to pass through the application part without damaging it.
  • the projection comprises a body and a tip.
  • the body part extends between the top of the cap and the tip.
  • the body part is not specifically limited and may have one of a conical, a cylindrical, or a rectangular shape.
  • the projection has a tip disposed opposite to the top of the cap.
  • the tip is not specifically limited and may have one of a truncated cone shape, a conical shape, a rounded shape, or a cylindrical shape, preferably a truncated cone shape.
  • the shape and size of the tip is configured according to the shape ans size of the outlet of the applicator, to ensure perfect sealing of the applicator. Given the location of the tip and its size, these shapes are easy to fabricate and can effectively seal the outlet of the applicator.
  • the body and the tip may be made of the same or different materials.
  • the body of the projection may advantageously be made up of material that is rigid so that it can provide mechanical stability to the projection and passes easily through the bristles.
  • the tip may be made of a rigid or a soft material, preferably soft.
  • the tip may be preferably made of elastomer, preferably silicone, which is a soft elastomer. This softness will help the tip to securely seal the outlet of the applicator.
  • the inner diameter of the cap undergoes changes in size between the top and the connection portion. These changes may be continuous or discontinuous.
  • the inner diameter of the cap may increase from the top of the cap till the connection portion of the cap, and the increase may be by about 30 %.
  • the diameter of the applicator generally increases from its top, where the application part is located, till its neck. This change in diameter of the cap is configured such that it holds the applicator firmly and eliminates the empty volume at the top by having a smaller diameter at its top.
  • the cap of the present invention may have multiple outer surfaces, including that at its top, head, the transition from the head to the base, and its base.
  • the outer surfaces each may have different shapes.
  • the head and base may either be conical or cylindrical in shape.
  • the outer shape at a transition from the head to the base is conical, which allows the cap to have a constant wall thickness and can also allow better manufacturability.
  • the cap of the present invention has at least one inlet for allowing the applicator, particularly the application part (bristles) and neck, to enter the cap for closure.
  • the inlet may have a rounded or preferably a conical surface. When the cap is closed, the bottom of the base touches the container. If the surface is conical at the begining of the inlet, it allows the cap to sit on the container in a manner which does not leave room for dust or particles to accumulate between the inlet and the container.
  • a conical geometry is more desirable than a pure cylindrical geometry at the inlet. A conical geometry provides a better fitting that will not allow the cap and the container to rub against each other causing friction, and thus the cap will not leave any friction marks on the container after being used mulitple times on closing tightly.
  • Another aspect of the present invention is an assembly comprising the cap, an applicator and a container.
  • the applicator of the present invention comprises an application part, outlet, neck and a connection base.
  • the application part of the applicator is a foam applicator, a massage surface, a plain surface, flock, or bristles, preferably bristles.
  • the applicator, excluding the application part may be made of plastic, preferably High-Density Polyethylene (HDPE) or PP. These varieties of plastics are rigid when solid and may be easily molded into a desired shape. Also, they are relatively inexpensive, and thus these would be prefered materials to make the applicator (excluding the application part).
  • HDPE High-Density Polyethylene
  • PP Polypropylene
  • the application part of the applicator comprises micro-bristles.
  • Micro-bristles are usually very fine and have a density of more than about 2 bristles per mm 2 .
  • These micro-bristles may be made of plastic, preferably polyethylene, more preferably Low-Density Polyethylene (LDPE).
  • LDPE Low-Density Polyethylene
  • the application part will dispense the material onto a surface of the user's body and hence, needs to be soft and flexible for a desirable dispensing of the contents.
  • Materials, such as LDPE can be extruded into fine fibers that are soft and flexible, and hence, are suitable for making the application part of the applicator.
  • the application part may have micro-bristles with a density of greater than or equal to about 3 bristles per mm 2 .
  • These fine bristles have a larger surface area (on the order of about 15 mm 2 ), as compared to normal bristles, and may hold larger volumes of fluid or dispense fluids more precisely. Thus, they allow the user to have a better control over the flow of the fluid.
  • the length of the application part is shorter than that of the alignment portion, so that the alignment portion guides the applicator part to center itself.
  • the cap of the present invention provides advantages over the prior art owing to its innovative shape, and the application part has an important role in dispensing the contents of the container.
  • Yet another aspect of the present invention is an assembly comprising the applicator, a container and the cap, wherein the container optionally holds a fluid for application.
  • the fluid is a medication.
  • the medication is a liquid for treatment of a symptom, injury or a disease, for example, present on a surface of the body, such as skin, eyes, or ears.
  • the fluid may be a cosmetic mass, such as a mascara.
  • the container may be made of plastic, metal or glass, preferably plastic.
  • the container of the present invention is made of HDPE.
  • the cap, the applicator and the container of the present invention can be made using standard manufacturing processes such as injection, slush, compression, or blow moulding or alternatively by thermoforming, vacuum forming or casting.
  • the assembly comprises a metering device.
  • This metering device allows the user to control the amount of fluid, contained in the container, that flows out through the outlet of the applicator.
  • the user could inadvertently deploy large quantities or the entire contents in the absence of a metering device, due to a misuse, or by pressing the container too hard. This undesirable situation is averted by providing a metering device.
  • the metering device ensures that the user will be able to dispense a controlled amount of contents from the container despite the application of a variable amount of force (by squeezing) to the container.
  • the metering device ensures that fluid emerges only "drop-by-drop" from the outlet, irrespective of the magnitude of force applied to dispense the fluid.
  • the metering device has an inlet, an intermediate storage reservoir and an outlet, which are all in fluid communication with each other. Also, the inlet of the metering device is in fluid communication with the container of the applicator, and the outlet of the metering device is in fluid communication with the outlet of the applicator.
  • the volume of the intermediate storage reservoir can be varied and thus the amount of fluid leaving the container can be controlled.
  • Conventional methods to meter the dose include modifing the outlet of the applicator, particularly the orifice radius. However, it is difficult to consistently manufacture orifices with a constant radius. The inventors of the present invention have found a better solution to meter the dose, by providing a metering device.
  • the metering device may be made from a plastic, preferably a thermoplastic, such as HDPE or PP.
  • the assembly comprises a dosing device in the form of a button.
  • the button is typically located on either the lateral surface of the container or the bottom of the container.
  • the button generally protudes out from the surface of the container and can be pressed.
  • the shape of the button may be substantially circular or polygonal, preferably circular or polygonal and the size and protrusion volume may be varied in accordance with the quantity of fluid to be administered.
  • the button is made up of a material that is soft, preferably an elastomer, more specifically thermoplastic elastomer (TPE).
  • TPE thermoplastic elastomer
  • the button may be fabricated to fasten it on to the container with the help of an adhesive.
  • the button may be manufactured together with the container by a hybrid extrusion or injection blow moulding or two component injection moulding process.
  • the force applied is restricted to the extent the button may be squeezed. This allows dosing of a determined amount of fluid to be dispensed and avoids wastage, which may have occurred in absence of such a dosing provision.
  • the assembly comprises a sachet, wherein the sachet holds a fluid for application, and wherein the sachet is inside the container, and is in fluid communication with the outlet of the applicator.
  • the sachet may be made of soft material and is flexible. When pressure is applied on the container, the sachet is squeezed, and the fluid contained in the sachet will flow out.
  • the sachet may be cylindrical or rectangular, or of any other suitable shape.
  • the sachet generally has a single opening, through which the fluid is filled. This opening is in fluid communication with the outlet of the applicator, so that when the user applies pressure the fluid in the sachet is dispensed.
  • the sachet may be made of single or multiple layers of plastic or metal or paper or fiber (laminate).
  • the sachet may be produced separately and be attached to the container or the applicator before or after filling it with the fluid.
  • the sachet may be produced while producing the container, by employing well known manufacturing techniques such as injection blow molding.
  • the button may be combined with the metering device or the sachet.
  • the button provides the user with a means of applying pressure to the container, in a convenient and precise manner.
  • the assembly may dispense the material, after being pressed/squeezed by the force transferred onto it by way of the user pressing the button.
  • 'soft' in the present application means a material is non-rigid and able to resume its normal (original) shape spontaneously after being stretched or compressed.
  • Geometric shapes and aspects refer to overall shapes and appearances and include shapes and aspects that do not substantially differ from the stated shape or aspect. For example, “round” therefore includes shapes that are substantially similar and differ only to a minor extent from a perfectly round shape, for example, due to tolerances and manufacturing constraints. Therefore “round” includes shapes which are substantially similar in function or capability to a round shape and/or which a person of ordinary skill in the art would consider to be substantially similar to a round shape.
