Description

Object of the Invention

The present invention relates to a rotating gradual dosing cap, which provides essential novelty characteristics and notable advantages over

10 to the means known and used for the same purposes in the current state of the art.

More in particular, the invention develops a rotating dosing cap specially designed, although not exclusively, for use with oil container containers, in particular with containers of the type commonly used in salad dressing operations and similar operations. The object plug of the present invention consists of two plastic pieces 20 mutually engaging with each other and capable of relative rotation of each other with respect to each other, each of which is provided with a partially perforated base to provide respective outlet holes which in by virtue of the rotation of one of the pieces with respect to the other fixed the

25 the neck of the container, the degree of confrontation of both holes can be regulated at will, thereby regulating the size of the oil hole, and providing the user with the ability to select the flow rate gradually from a minimum drip when There is not

30 confrontation between the holes of the bases to a maximum flow when the holes of both bases occupy mutually overlapping positions.

The scope of the invention is within the industrial sector dedicated to the

manufacture of injected caps for containers.

Background and Summary of the Invention

It is a common occurrence in the current state of the art

5 Use oilers or other oil container containers for salad dressing operations and the like. The containers or containers used for these purposes incorporate some type of outlet duct that usually consist of small diameter passages

10 to allow the user to control as much as possible the amount of oil poured during the time the dressing operation lasts. however, although it should be recognized that conventional oil companies have fulfilled over time the normal function for which

15 were developed, it is no less true that they also suffer from some practical inconveniences. As an example of the above, two main drawbacks could be cited, namely, a first drawback that derives from the fact that as the outlet duct of a

20 reduced diameter and therefore of a very limited flow, the oiler is practical when it comes to dressing an individual or small-sized salad in which a relatively small amount of oil is required, but it is not so much when it comes to dressing collective salads, is

25 say for a greater number of people, in which case the flow limitation requires a greater amount of manipulation and time; the other drawback is that by having a single outlet of limited flow, it is necessary that the air drawn into the container

30 as product is extracted, also circulate through the same oil outlet conduit, making the output intermittent, with continuous interruptions that impair the extraction operation by causing the oil to flow out on impulses.

It is already known in the state of the art an oiler equipped with a plug with which the problem of slow oil leakage is solved, for which the plug has two passages of different sizes, in diagonally opposite positions, so that Depending on the inclination that the user gives the container to one side or the other, the oil reaches one or the other outlet, providing a flow rate of greater or lesser content depending on the size of the outlet used. In each case, the unused outlet provides an air passage that prevents the formation of spurts in the outflow.

Despite this improved oil cap, there is still a need in the state of the art for a container with a cap such that it allows the user to select a variable oil flow rate so that he can adjust it to his needs in each case. This has been the objective of the present invention, which has been achieved by means of the cap that will be described in the following, whose essential characteristics are included in the characterizing portion of the attached claim 1.

In essence, the dosing cap of the present invention is constituted by two concentric pieces configured as cylindrical bodies, with diameters adjusted so that one piece can be fitted inside the other, and the inner diameter of the inner part being such which allows its adaptation to the neck of a container or container containing the oil. The coupling between pieces is such that it allows a rotation of one with respect to the other, for the purpose of varying the mutual positioning of both pieces with each other. Each of the pieces includes a flat transverse base, in positions such that the respective bases of both pieces are superimposed between

yes, each of the bases being sectioned according to approximately central diameter, and incorporating a first through hole of reduced diameter in a centered position close to the perimeter edge of the closed semi-base. In another embodiment, the open semi-base could be replaced by a second through hole of larger diameter than the first through hole mentioned. Thus, it is understood that by turning 18Oo of one piece of the cap, for example an external part, with respect to the other part, for example the internal part, the respective open semi-bases of both parts can be carried from a position of total confrontation with a closed position in which each open semi-base of each piece faces a closed semi-base of the other piece, leaving the first holes of reduced diameter of which they consist of only 1 through holes both bases. With this, the oil can be poured either by a wide step of variable size depending on the position in which the user decides to position a piece with respect to the other, or

20 either by a reduced passage provided by any one of the first holes consisting of said closed semi-bases.

The cap is made entirely based on a

Moldable material, preferably an injection moldable plastic, and for ease of use may be provided with some external projection that provides some type of spout.

Description of the Preferred Embodiment As mentioned above, the detailed description of the preferred embodiment of the object of the invention will be carried out in the following with the help of the attached drawings, through which the same numerical references are used to designate the same or similar parts. So, attending

First of all, to Figure 1 of the drawings, a representation of two pieces identified with numerical references 1 and 2, designed and sized to admit the coupling of an external part, in this case part 1, can be seen on the other part 2 which in this example is the internal part and with both parts mutually coupled together constitute the dosing cap of the present invention. Both pieces 1 and 2 are of general cylindrical configuration, internally hollow, whose internal and external diameters are such that they provide a tight concentric coupling, with the possibility of turning one in relation to the other. The outer part 1 includes a central coaxial formation 4, also cylindrical, around which a concentric annular path housing runs with this central portion 4 (not visible in Figure 1), also counting said central coaxial formation 4 with a transverse base at a previously established height, coinciding with the lower end (according to the position in which it appears in the drawing) of said central coaxial formation 4, of which approximately a portion equivalent to (or somewhat smaller) half of the surface of the base is open (hereinafter, semi-open), to provide a passage for the oil of great flow capacity, while the other base portion indicated with reference 3b is closed (in the following, semi- closed base). The closed semi-base includes a first hole 5 (partially visible in Figure 1) in a centered position close to the perimeter line of connection between the semi-base 3b and the wall of the central coaxial portion 4. Finally, so Conventionally, the outer part 1 of the cap has been provided with a projection 14 of curvilinear transverse development, which in this case emerges from the aforementioned internal coaxial formation 4, which affects approximately half the length of the circumference and extends according to the direction

longitudinally at a distance sufficient to constitute a spout of the product contained inside the package (not shown) to which the cap is applied.

5 Equivalently, part 2 that this case constitutes the inner part of the cap and that has a

Inner diameter sized to allow coupling to the neck of a container or container containing the oil to be dispensed, it is designed to include a cylindrical coaxial inner formation 6, sized to receive the cylindrical coaxial internal formation 4 of the outer part 1 when both pieces are coupled to each other. As in the case of the outer piece 1, the piece 2 transversely includes a base in 1 5 coinciding with the lower end of the mentioned internal coaxial formation 6, of which a base portion 6a equivalent to (or somewhat smaller than ) approximately half of its surface is open (in the following, semi-open base), while the rest of the base 6b is closed (in the following, semi-closed base). The closed semi-base 6b includes a through hole 7, partially visible in the Figure, in a centered position close to the perimeter line of encounter between the base portion 6b and the inner wall of the cylindrical coaxial formation 6. 25 Additionally, this piece 2 includes a pin 9 which acts as a stop in the rotation of the outer piece 1 with respect to the inner piece 2 as will be explained later in relation to Figure 6 of the drawings, which is projected in the direction of the longitudinal axis at a short height from the

30 perimeter edge of the internal cylindrical formation 6.

Figures 2 and 3 are respectively illustrations in plan and cross-section along line 111-111 of Figure 2, of the outer part 1 of the dosing cap of the

35 present invention, which allow more appreciation

Clear the construction details of the piece. Thus, in Figure 2 the difference in surface area occupied by the open semi-base 3a can be seen slightly with respect to the slightly larger surface of the closed semi-base 3b.

5 Likewise, the location of the first hole 5 of reduced diameter is appreciable, in positional coincidence with the diametral axis that passes through the center of the open semi-base 3a.

1O For its part, Figure 3 shows the relative position of the internal coaxial formation 4, and around the latter the formation of the housing 8 as an annular channel that surrounds said formation and is laterally delimited by two walls. , 11 circulars

15 concentric, low rise.

Similarly, Figures 4 and 5 illustrate respectively plan and section views along the line v-v of Figure 4 of the internal cylindrical part 2, by

20 which can be appreciated the construction details of the piece. In the plan view of Figure 4, both semi-bases 6a and 6b are visible, of which the open semi-base 6a has a slightly smaller surface extension than the closed semi-base 6b, also being

The location of the second hole 7 of reduced dimensions in a centered position in front of the central diametral line of the open semi-base 6a is noticeable. The cross section v-v of Figure 5 shows the formation of two recesses 12, 13 in relation to the upper edge

30 (according to the position in which it appears in the drawing) in which the central coaxial formation 6 is located, in corresponding positions coinciding with the walls 10, 11 that delimit the annular housing 8 of the outer part 1 of the plug, also being appreciated the position occupied by the stud

35 9 between both recess is 12, 13, and therefore in

correspondence with the position of said annular channel 8 of the outer part 1 of the plug.

As mentioned above, the plug of the invention is obtained by mutually concentric coupling of both external 1 and internal 2 pieces, with the possibility of turning one over the other. This arrangement can be well appreciated in the sectional view shown in Figure 6, where both pieces appear perfectly coupled to each other with the outer piece 1 housing in its inner space concentrically to the inner piece 2, with the walls la, 11 delimiters of the annular housing 8 supported by the recesses 12, 13 of the internal part 2 and therefore serving as a limit stop for insertion between the pieces, with the pin 9 inside said annular housing 8, and with the respective bases associated with the inner cylindrical coaxial formations 4, 6 of both parts superimposed on each other. In the representation shown in Figure 6, the open semi-base 6a of the inner part 2 faces the closed half-base 3b of the outer part 1 and therefore, the first hole 5 of reduced diameter associated with said base of the external part 1, while the open semi-base 3a of the external part 1 faces the closed semi-base 6b of the internal part 2, and therefore the second hole 7 of reduced diameter. In that position, the dosing cap would only allow a reduced flow supply through the hole 7 of the inner part 2.

Additionally, the cap includes retaining means of both external 1 and internal 2 parts in the condition of mutually coupled to prevent accidental disassembly thereof. These means are visible in Figure 6, and consist essentially of several formations 15 as protrusions in the form of teeth projected inwards from several equidistant positions close to the

lower edge of said outer part 1 distributed along the circumferential length of the piece, which are positioned by debonding or the lower perimeter edge of the inner part 2, thereby hindering the

possibility of separation between pieces.

Finally, reference will now be made to Figure 6 of the drawings. This Figure shows five representations identified with consecutive references (a) to (e) e

1O illustrative of the dosing capacity of the output flow from inside a container to which the cap of the present invention is applied. The positional variation is made thanks to the turning capacity of an external part 1 with respect to the other internal part 2 of the

15 plug, as indicated by arrow "F". Starting from the first illustration identified with (a), it can be seen that the position of the outer part 1 is such that both semi-bases are perfectly superimposed, just like the first hole 5 on the second hole 7

20 (not visible in the representation), and where the flow passage corresponds to a flow of equivalent size to the

,

dimension of the open semi-bases of both pieces.

Based on the position of the representation

25 (a), in the representation (b) the external part 1 has been rotated 1/8 turn in the direction of the arrow "F", whereby the passage opening has been correspondingly reduced to 3/4 of the initial size, and now holes 5 and 7 are not facing each other, but

30 each of them to the respective closed semi-base of the other piece.

In representation (c), the piece has been turned 1/4 turn in the direction of the arrow "F" with respect to the initial position, with holes 5 and 7 of each

base facing the respective closed semi-base of the other piece and having reduced the size of the passage opening to a value of 1/2 with respect to the size of the initial opening.

In the representation (d), the piece has been rotated an amount of 3/8 of a turn in the direction of the arrow "F" from the initial position, leaving a passage opening equivalent to 1/4 of the size of the opening of He passed

10, and now the holes 5 and 7 are free without the closed half-bases obstruct them by confrontation with them.

Finally, in the representation (e) the piece appears

15 1 rotated half a turn (ie 180 °) in the direction of the arrow "F" with respect to the initial position, both pieces being left so that the closed semi-bases 3b, 6b of both external 1 and internal 2 parts are face the open semi-bases of the other respective piece, preventing

20 in such a way that flow may exist except for one of the holes S, 7 of reduced diameter, in particular through the second hole (7) of reduced diameter associated with the closed semi-base 6b.

25 As will be understood, the opening of the passage zone from the total closing position of the representation (e) is obtained by turning the outer part 1 in the opposite direction to the arrow "Fil.

On the other hand, it should be understood that the back portions referred to in the representations (a) to (e) are illustrative only, it being possible to position the outer part 1 in any intermediate position comprised between both extreme positions. This makes it easier for

35 user an effective means of progressive dosing, to

will, of the flow of product extracted from any container to which the cap of the invention has been previously attached.

Notwithstanding the foregoing, and since the description given corresponds only to a preferred embodiment of the invention, it will be understood that within its essentiality multiple can be introduced

5 It is not considered necessary to make the content of this description more extensive so that a person skilled in the art can understand its scope and the advantages derived from it, as well as carry out the practice of your object.

15 variations of detail, also protected, that may affect the shape, size or manufacturing materials of the assembly or its parts, without this implying any alteration of the invention as a whole, delimited only by the claims that are
