Abstract
Description
- The present invention relates to an improved plug for delivering liquids in bottles, vials or the like, characterized in that said plug comprises an inner cap, having an upwardly projecting inner sealing ring element and ending with a top liquid scraping element.
- Said liquid scraping element defines, on the outside thereof, a top funnel-like ring or annular element, joining with conical slots, therethrough the liquid is ejected, and allowing the liquid held in the gap of the two plug elements to be easily recovered.
- This feature constitutes one of the advantages of the plug according to the present invention, with respect to the commercially available plugs conventionally including shutter means.
- In this connection, another advantage of the subject improved plug is that it provides, under any conditions, a perfect sealing with respect to the delivered liquid, which cannot be ejected from possible gaps which, in conventional plugs, are formed between the inner cap and the outer cap of the plug.
- The subject improved plug, in particular, is very simple construction-wise, can be easily made starting from a lot of easily available plastic materials, since it has a contour that is suitable for an injection molding process, and can be easily applied to the liquid vial or vessel by very simple assembling operations.
- Another advantage of the subject plug is that the inner cap ends, at its top central portion, with a shutter element cooperating with the liquid delivery hole, thereby opening and closing, to a desired degree, the inventive plug, thereby allowing a controlled variable amount of liquid to be easily delivered.
- The above and other characteristics, of functional and constructional nature, of the subject improved plug, will become more apparent hereinafter from the following detailed disclosure thereof, with reference to the figures of the accompanying drawings, where:
- Figure 1 is a cross-sectioned side view illustrating the improved plug according to the invention, in a closing position thereof;
- Figure 2 is a further cross-sectioned side view illustrating the plug according to the invention in a closing position thereof;
- Figure 3 is yet another cross-sectioned side view illustrating the improved plug according to the invention, in an opening position thereof; and
- Figure 4 is a top cross-sectioned view illustrating that same plug.
-
- With reference to the number references of the figures of the accompanying drawings, the subject improved plug, generally indicated by the
reference number 1, has been specifically designed for controllably delivering liquids and is provided with aninner cap 3, including an upwardly projecting innersealing ring element 19. - Said sealing
inner ring element 19 ends with a topliquid scraping element 4, defining on the outside thereof a funnel-like top ring orannular element 9. - This funnel-like ring element is adjoining with a series of
conical slots 8, therethrough the liquid is delivered and recovered, i.e. is recovered that portion of the liquid which is not used in the specific application. - The
inner cap 3 ends, at the top thereof, with a central shutter element, cooperating with theliquid delivery hole 6, to open and close the subject plug, thereby allowing a controlled amount of liquid to be delivered or metered. - The
plug 1 comprises moreover anouter cap 2, which is adapted to rotate with respect to theinner cap 3, and it performs, in addition to a partial rotary movement, also an upward and downward vertical displacement movement. - Such an effect will cause a variable opening of the
delivery hole 6 which engages, under given conditions and in a different degree, with thecentral shutter element 5 formed in the body of theinner cap 3. - The
outer cap 2 is moreover provided with a downward projectingsealing ring 7 provided for engaging with an annular hollow, as the plug is clamped between an outer guide and sealingring 12 and aninner sealing ring 19, which projects upward for a distance larger than the projecting distance of the first ring. - The outer guide and
sealing ring 12 and theinner sealing ring 19, in turn, define an annular hollow 21, in which the downward projectingannular element 7 is caused to tightly engage. - The
inner cap 3 is moreover provided with abottom lug 20 entering the inside of the neck of thebottle 24. - The above mentioned axial movement performed by the
outer cap 2 with respect to theinner cap 3 is obtained by a partial rotary movement of theouter cap 2, which is provided withhelical contour hollows 14 engaging with projectingtooth elements 13 formed on the outer surface of theinner cap 3. - In this connection it should be pointed out that the
inner cap 3 is provided with an inward projectingannular lug 20, adapted to be arranged between and enters the inside of aportion 24 of the bottle neck, contacting atop portion 25 of theinner cap 3. - Said
inner cap 3, together with the downward projectingannular lug 20 provides a perfect sealing for the liquid, under any use conditions. - With reference to Figure 4, a
helical contour hollow 14 is herein provided, housing therein the three projectingtooth elements 13 formed on the inner cap and spaced from one another at 120°. - Moreover, at the inner wall of the
outer cap 2small teeth 27 are also provided. - At the top portion of the
inner cap 3, moreover, areridge elements 15 adapted to facilitate the draining and recovering of the liquid are moreover provided. - As shown, the
small teeth 27 engage with correspondingsmall teeth 18 formed on the outer side surface of theinner cap 3, in order to clearly indicate a full opening and closing position thereof. - The
lugs inner cap 3 are so designed and sized as to clamp thetop lug 24 of the bottle neck, thereby preventing the plug from being accidentally thread off or disengaged as it is opened. - From the above disclosure it should be apparent that the subject improved plug is provided with very advantageous functional and constructional characteristics, allowing both an easy delivering and an easy and quick recovering of liquids in general.
- While the inventive improved plug has been hereinabove disclosed by way of an illustrative and not limitative example, it should be apparent that it is susceptible to many modifications and variations all of which will come within the scope of the invention, as defined by the accompanying claims.
