Abstract

A dispensing cap (22) for the dispensing of a liquid composition from a squeeze bottle (10) is provided. The dispensing cap provides a more uniform delivery of the liquid composition being dispensed from the squeeze bottle even with low levels of liquid being present in the squeeze bottle.

Description

COMPRESSABLE BOTTLE DISTRIBUTOR FIELD OF THE INVENTION The invention relates to a compressible bottle and dispenser, particularly those that are used to distribute aqueous or liquid compositions.

BACKGROUND OF THE INVENTION The increase of environmental problems with the use of aerosol products, particularly those aerosol products that include chlorofluorocarbon propellants that are suspected to be dangerous for the ozone layer has promoted interest in the use of alternative distribution systems. . One of those alternative distribution systems that is economical and satisfactory for the distribution of aqueous or liquid compositions are compressible type bottles. Typically, such compressible type bottles include a portion of a flexible bottle or bottle, which is intended to be compressed by the consumer, and which contains a liquid composition. Upon compression of this portion of bottle or bottle, the liquid composition is forced up a deep tube extending downwardly from the dispensing cap, and is therefore distributed through the dispensing cap. Liquid compositions that can be distributed include, for example, cleaning compositions as well as medical compositions. Exemplary squeeze-type bottles include, for example, those described in U.S. Patent No. 4,014,467 to Silverman, as well as U.S. Patent No. 5,301,846 to Schmitz. Disadvantage inherent in the use of compressible type bottles resides in the fact that typically, not all liquid compositions provided to a consumer are uniformly distributed. This is particularly true when the level of liquid composition contained within the bottle drops below half, and particularly drops to below one quarter of the fluid volume that was originally provided. Thus, when the compressible type bottle contains a total amount of the composition, the compression of the flexible bottle portion generally provides a very satisfactory spray pattern on the dispensing cap. However, as the liquid composition is depleted, and the non-liquid volume of the bottle (air gap) grows, the subsequent distribution of the liquid composition by the consumer usually provides a weak flow and / or a very good spray pattern. Poor coming out of the distribution cover. Naturally, this is disadvantageous both from a technical and consumer point of view. From a technical point of view, the loss of the initial, satisfactory spray pattern results in a loss of the covered area when the product is distributed. This forces the consumer to distribute more product to provide more uniform coverage over a given area. On the point of view of a consumer, this can lead to dissatisfaction with the product, since it appears that the compressible bottle is defective. In addition, the consumer is also forced to distribute a larger amount of liquid composition to ensure uniform coverage of an area, due to the loss and degradation of spray patterns.

SUMMARY OF THE INVENTION The present invention solves and overcomes those technical disadvantages. Accordingly, an aspect of the invention provides a compressible bottle for dispensing the liquid composition, particularly a cleaning composition and / or domestic sanitizer, compressible bottle which includes a dispensing cap having a configuration that provides a better distribution of the liquid composition. In another aspect of the invention, a dispensing cap suitable for use with a compressible bottle and dispensing cap is provided which provides an improved spray pattern regardless of the level of liquid contained within the compressible bottle. According to an even further aspect of the invention, there is provided a process for improving the spray distribution characteristics of compressible type bottles, which comprises the steps of: providing an improved dispensing cap having a suitable configuration to provide a pattern of improved and more consistent dew to a liquid composition leaving the bottle, regardless of the level of liquid composition remaining in the compressible bottle.BRIEF DESCRIPTION OF THE DRAWINGS Other aspects of the invention will become more evident from the reading of the following specification.

DETAILED DESCRIPTION OF THE PREFERRED MODALITIES OF THE INVENTION According to one aspect of the invention, a compressible bottle generally described as (10) is provided in Figure 1. The compressible bottle includes at least one deformable side wall (12) terminating at a lower end (14) and ends at another end in a neck (16) through which a liquid composition can enter the inner volume (18) of the compressible bottle (10). An amount of liquid composition (20) is also described in Figure 1. The neck (16) forms a liquid-tight seal with a dispensing cap (22) through which the liquid composition (20) is distributed. With respect to the compressible bottle (10), the dispensing cap (22) and the addition tube (40), these can be made of any material that is flexible, and that is sufficiently chemically resistant, so that it is not degraded undesirably for containing the liquid composition (20) for reasonably long periods of time, i.e. several weeks, several months or more. For example, particular advantageous materials that can be used to produce the compressible bottle (10) include various polymers, including but not limited to: polyolefins such as polyethylene, polypropylene, polybutylene; pollamides including various grades of nylons, especially nylon 6 and nylon 66; polyalkylene terephthalates such as polyethylene terephthalates and polybutylene terephthalates, as well as mixtures or combinations of these polymers. Other construction materials useful for the formation of flexible bottles that are currently known in the art can also be used and enjoy the benefits of the present invention.

Turning now to the dispensing cover (22), the dispensing cover (22) includes a nozzle-shaped portion (24) which extends upwardly from a flange (26). The upper portion in the form of a nozzle (24) also includes a discharge orifice (28) incorporated therein. Extending downwardly from a flange (26) is an outer circumferential skirt (30) which is provided for coupling the outer wall (31) of the neck (16) of the compressible bottle (10). The outer circumferential skirt (30) and the neck (16) can be added by any suitable coupling means, including but not limited to coupling threads on both of the outer circumferential skirt (30) and the neck (16), or any other suitable means. The dispensing cap (22) also includes an inner circumferential skirt (34) extending downwardly from the flange (26). The inner circumferential skirt (34) having an outer wall (36) which is provided for coupling the inner wall (32) of the neck (16) of the compressible bottle (10). Desirably a liquid tight seal is provided by joining the portions of the dispensing cap (22) and the neck (16) of the compressible bottle (10). The dispensing cap (22) also includes a projection (38) extending downwardly from the flange (26) into the compressible bottle (10). The projection (38) also extends upwardly beyond the flange (26) and forms a portion of the nozzle-shaped upper portion (24) of the dispensing cap (22). A portion of the projection (38) is dimensioned to hold a portion of the dip tube (40). The dip tube (40) includes a proximal end portion (42) which is inserted into and retained by the projection (38), as well as a distal end portion (44) which extends downwardly into the interior of the bottle compressible and ends near the bottom wall (14) thereof. The projection (38) has included in its construction an air flow channel (46), which will be described in greater detail here later. In operation, a consumer holds the compressed bottle (10) around the side wall (12) thereof and compresses the side wall (12). This induces the flow of the liquid composition (20) towards the distal end portion (44) of the dip tube where the pressure exerted on the side wall (12) of the compressible bottle (10) induces the flow towards and along the proximal end portion (42) of the dip tube. The liquid exiting from the proximal end portion of the dip tube enters a mixing chamber (50) located just beyond the proximal end portion (42) of the dip tube (40). At the same time, any air within the interior volume (18) of the compressible bottle (10) is also forced simultaneously into the air flow channel (46) where it is mixed in the mixing chamber (50) with the liquid composition ( 20) exiting the proximal end portion (42) of the dip tube (40), and forcing both the liquid composition and the air to exit via the discharge orifice (28) more desirably in the form of a spray pattern. spray of boats. The dispensing cap according to the invention provides superior distribution characteristics of the liquid composition (20) due to the specific construction of the distribution covers (22) and the integral portions thereof. Turning now to Figure A, there is described a cross section along the reference lines R-R of Figure 1 of a portion of a conventional dispensing cap according to the prior art. As shown in Figure 1A, there is provided an upper portion in the form of a nozzle (24A) and a portion of a dip tube (40A). Three reinforcements, reinforcement (Bl), reinforcement (B2) and reinforcement (B3) are also shown in the Figure. These three reinforcements are integrally formed as part of the nozzle-shaped upper portion (24A) and extend radially downward. Each of these reinforcements includes an end portion, which comes in contact with and retains the outer wall (52) of the dip tube (40A). The dip tube (40A) is placed by physical friction between the respective end portions of the reinforcements, specifically between the end portion (El) of reinforcement (Bl), the end portion (E2) of the reinforcement (B2) and the end portion (E3) of the reinforcement (B3). It should be understood that each of these reinforcements has a height which can not be observed since it extends up and down from which the figure is drawn. It should be understood that each of these reinforcements (Bl), (B2) and (B3) have a height whose length is approximately equal to, or may be less than the length of the portion of the proximal end portion (42) of the dip tube (40) inserted into the projection ( 38), as can be more readily understood when seen in Figure 1. As will be understood from Figure A, the spaces between the outer wall (52) of the dip tube (40A) and the supreme mouthpiece portion (24A) ) between the spaces occupied by the reinforcements (Bl), (B2) and (B3) define channels (Al), (A2) and (A3) as shown in Figure A. These channels are provided for bidirectional flow of air from the external environment to the inner volume of the compressible bottle (10). Such an arrangement of the dip tube and the distribution layer (22), however, is disadvantageous, since it results in poor distribution characteristics especially when the liquid composition (20) contained within the compressible bottle (10) is smaller than half, particularly less than 25% of the total available inner volume (18) of the compressible bottle (10). With the use of the prior art dispensing cap having an arrangement of a supreme nozzle-shaped portion as described in Figure A, when the compressible bottle (10) is compressed, a substantial amount of air is compressed within of the interior volume (1T) and is quickly expelled through the channels (Al), (A2) and (A3). This allows faster compression of the bottle, but simultaneously decreases the flow of the liquid composition (20) which is induced to flow up the dip tube (40) and out of the distribution cover (22). Additionally, the likelihood of forming a desirable spray pattern of liquid exiting the dispensing cap (22) through the discharge orifice is also substantially reduced since when the larger volume of air is displaced out of the discharge orifice (28), only a minor portion acts to mix with the liquid composition (20) within the mixing chamber (50) and forms a desirable spray pattern. The dispensing caps according to the present invention overcome many, if not all, of those technical disadvantages inherent in the use of the prior art covers, particularly those with the structure illustrated in Figure A. Turning to Figure 2, in it is provided a cross-sectional view of a nozzle-shaped upper portion (24) according to a first embodiment of the invention. This cross-sectional view corresponds to the line RR as shown in Figure 1, and particularly with reference to Figures 5 and 6. As shown in Figure 2, the upper portion in the form of nozzle (24) has an orifice (55) inside which the proximal end portion (42) is placed the dip tube (40). The upper portion in the form of a nozzle (24) is also interrupted by a rectangular air flow channel (46). Although not shown in Figure 2, it should be understood that the air flow channel has a dimension at a height that can vary from a minimum height, generally one millimeter to one height, which height is the same as, or that it extends along the proximal end portion (42) of the dip tube (40) which is inserted in the upper portion in the form of a nozzle (24). It should also be understood that the air flow channel (46) extends in a direction which is essentially parallel to the axis of the proximal end portion (42) of the dip tube (40). According to the embodiment illustrated in Figure 2, the air flow channel (46) is attached on three sides of the material that is used to form the upper portion in the form of nozzle (24) thereof, but has an open end (54), which, however, is sealed when the proximal end portion (42) of the dip tube (40) is inserted in the upper portion in the form of a nozzle (24). As can be seen from the similar inspection compared to the cross section of the nozzle-shaped upper portion (24) according to the invention without its prior art (shown in Figure A) the cross-sectional area of the flow channel of air (46) is substantially smaller than the cross-sectional area of the air passages (Al), (A2) and (A3). The present inventors have surprisingly found that the spray characteristics and distribution characteristics are substantially improved when the cross-sectional area of the air flow (56) is not greater than the cross-sectional area of the dip tube. (58). It is preferred, in effect, that the cross-sectional area of the air flow channel (56) be less than 80% of the cross-sectional area of the open portion of the dip tube (58), more preferably, less than 50%, still more preferably less than 30% of the cross-sectional area of the open part of the dip tube (58). It should be understood that there is a need for an air flow channel comprised of one or more air passages, passages each of which admits the passage of air therethrough. The inventors have discovered that, surprisingly, that a substantial reduction the amount of air that is allowed to leave the compressible bottle (10) when it is compressed has a double benefit. First, a reduction in the volume of air that is let out when the compressible nozzle is compressed ensures that the pressure accumulated in the interior volume (18) of the compressible bottle (10) acts to increase the pressure on the liquid composition (20) contained within the compressible bottle and more effectively force it upwards through the dip tube (40). This is particularly important when the liquid composition (20) occupies 50%, or particularly 25% less, of the available inner volume (18) of the compressible bottle. In this way, the majority is that the entire total amount of the liquid composition (20) can be expelled from the compressible bottle and placed for the purpose for which it is intended (cleaning, sanitizing, deodorizing, etc.). Surprisingly it has been observed that with the amount of reduction of the air coming out via the distribution cover (22), a substantial increase in the velocity of the air leaving the interior volume (18) through the air flow channel (46) greatly improves the mixing characteristics within the mixing chamber (50) and consequently improves the spray pattern of the liquid composition being distributed. It is surprising when it was observed that the desirable spray pattern was maintained substantially both when the liquid composition (20) occupied most of the available inner volume (18) of the compressed bottle (10) as well as when the liquid composition (20) occupied only a smaller portion of the inner volume (18) of the compressible bottle (10). These dew performance characteristics on the service life of the distribution package satisfied the technical and consumer benefits described above. Namely, according to the particular preferred embodiments of the dispensing caps according to the invention, the spray bottles containing a liquid composition provided a very uniform and satisfactory spray distribution pattern during the useful life of the distribution package and the package contained in it. This has not been possible with the distribution covers, or spray bottle distribution packages known until now. Turning now to Figure 3, there is provided an alternative embodiment of a portion of a dispensing cap according to the present invention. Described in Figure 3 is again a cross-sectional view of a nozzle-shaped upper portion (24) taken along the reference lines RR as shown generally in Figure 1, and especially Figures 5 and 6. The nozzle-shaped upper portion (24) includes a hole (55) into which the proximal end portion of the dip tube (40) is placed, but which includes two channels of the air flow (46). As discussed with reference to Figure 2, those air flow channels (46) have a dimension as little as about one millimeter, or that can extend the entire length of the proximal end portion (42) of the dip tube (40), over the entire length. As in Figure 2, the air flow channels (46) in Figure 3 have a cross-sectional area (56) and each has open ends (54) which are in contact with the outer wall (52) of the dip tube (40) and again, the interior of the dip tube (50) also has a cross sectional area (58). In opposition to the embodiment shown in Figure 2, as in the embodiment of Figure 3 which includes two air flow channels, it should be understood that the total cross-sectional areas (56) of the two air flow channels (46) is equal to, but desirably less than, the total cross-sectional area of the interior (58) of the dip tube (40). Desirably, the total of that cross-sectional series (56) is less than 80% of the cross-sectional area of the interior of the dip tube (58), more desirably less than 50%, even more desirable is less than 30% of the cross-sectional area of inner section (58) in the dip tube (40). The embodiment according to Figure 3 provides the additional advantage that two air flow channels are provided, which provide greater turbulence in the mixing chamber (50) of the distribution cover (22) according to the invention. This increase in turbulence improves the foaming characteristics of a liquid composition, which may be particularly desirable if it is intended. This increase in turbulence improves the spray pattern of a liquid composition (20) that is being distributed via the distribution cover (22), as well. Attention is also drawn to the fact that in both Figures, 2 and 3, the air flow channels (46) are rectangular and according to those two preferred embodiments, the geometries of the air flow channels are selected for provide sharp edges. That is, when the compressible bottle is compressed, the air that is pressurized within the interior volume (18) of the compressible bottle (10) above the level of the liquid composition (20) meets the acute bottom edge (not shown) of the upper portion in the form of nozzle (24) and thus there is a greater probability that a turbulent air flow is induced. Again, it is believed that this turbulent air flow improves the mixing efficiency that occurs in the mixing chamber (50) of the dispensing lid (22). Also, the configuration of the rectangular cross section of the air flow channels (46) as shown in Figures 2 and 3 also provides a lower degree of compressibility, which aids in the insertion of the proximal end portion (42) of the dip tube (40) which is inserted in the projection (38) of the distribution cover (22). Turning now to Figure 4 therein is described a further embodiment of the upper portion in the form of nozzle (24) according to the invention. It discloses an upper portion in the form of nozzle (24) having an air flow channel (46), in it, however, in the form of a circular hole which extends parallel to the hole (55) within from which the dip tube (40) is placed. As with the previous embodiments illustrated in Figures 2 and 3, the cross-sectional area of the air flow channel (46) in the embodiment in Figure 4 is desirably no greater than the cross-sectional area of the air flow channel. immersion tube (58). More desirably, the cross-sectional area of the air flow channel (46) is not greater than 80%, more preferably not more than 50%, but still more preferably not more than 30% of the interior of the cross section of the dip tube (58). However, unlike the modalities shown in Figures 2 and 3, no portion of the air flow channel (46) comes into contact with the orifice or dip tube (40) contained within the orifice. Although, it has been shown in Figures 2 and 3 that a wall of the air flow channel (46) is formed by the outer wall of the dip tube 52, that, however, is not a limitation, but rather a matter of convenience to facilitate insertion of the proximal end portion (42) of the dip tube (40). As noted above, the proximal end portion (42) of the dip tube (40) is conveniently retained in the projection (38) by friction adjustment, although other means may also be used. The intersection of the air flow channel (46) with the projection (55) from which the dip tube (40) is to be placed, allows the slight expansion of the orifice (55) when the dip tube (40) is inserted will therefore be necessary. Turning now to Figure 5, there is shown a cross-sectional view of a preferred embodiment of the dispensing cap (22) mounted on the neck (16) of a compressible bottle (10). According to this embodiment, the neck (10) includes two or more projections (60), which cooperate with cavities similarly configured (62) extending towards the circumferential skirt (30) of the distribution layer (22) .

For convenience in assembling the distribution layer 22 with the compressible bottle 10, the inner lower periphery 64 of the outer circumferential skirt 30 is provided with a chamfer or chamfer. As can also be seen in Figure 5, the inner circumferential skirt (34) is also configured to provide a low tolerance fit with the neck (16). Desirably, the junction between the inner circumferential skirt (34), the flange (26) and at least a portion of the outer circumferential skirt (34) provides a hermetic seal to the liquids or more preferably, hermetic with the neck ( 16). It should be understood that although the projections (60) and the corresponding cavities (62) are described in Figure 5, other means may be used to attach the dispensing cap (22) to the compressible bottle, particularly in the neck (16) of the same, with the condition that a liquid-tight seal is formed between the distribution cover (22) and the neck (16). By way of non-limiting example, these include corresponding sets of coupling threads, which may be coupled between portions of the distribution layer and portions of the neck (16); adhesives that can be introduced between portions of the dispensing lid (22) and the neck (16), as well as the use of additional elements such as a thermally shrinkable band or band, which can fit a portion of the dispensing lid (22). ) and the neck (16). It was also contemplated that the tolerances of the dispensing cap (22) and the neck (16) are sufficiently narrow, so that a simple frictional coupling of those elements provides a fluid-tight seal between them. To assist in the placement of the distribution layer (22) on the compressible bottle (10), especially the neck (16) thereof, the lower outer wall (36) of the inner circumferential skirt (36) can be provided with a bevel or chamfer (37) As shown in Figure 5, the dip tube (40) is inserted and retained by the projection (38) and is also positioned so that its proximal end (42) extends up and beyond the ridge inside the interior of the nozzle-shaped upper portion (24). As also seen in Figure 5, the air flow channel (46) is also shown here, which must be understood as an air flow channel having a generally rectangular cross section and corresponding to that described in the Figure 2. As can be seen, the air flow channel (46) forms a cavity in the projection (38) and extends in a direction parallel to the axis of the proximal end portion (42) of the dip tube (40) inserted in the projection (38). In this Figure, the air flow channel (46) has one end (54) near one end of the projection (38) and the air flow channel (46) extends upwardly beyond the proximal end of the tube of immersion and into the mixing chamber (50). The air flow channel (46) has a side formed by the outer wall (52) of the dip tube (40), while its other sides are formed integrally as part of the distribution cover (22). The embodiment of the dispensing cap (22) illustrated in Figure 5 also includes a sealing cap portion (66), which is flexibly attached to a portion of the dispensing cap (22) by means of a joint. or hinge (68). The hinge (68) can be integrally formed as a "live joint" of the sealing cap (66) and the dispensing cap (22), or it can be any other flexible element or device by means of which the sealing cap (66) ) can be removed, but not necessarily detached from the distribution cover (22). As shown in this embodiment, the sealing cap (66) includes a lid-shaped plate (70) extending from a face thereof., an outer circumferential cover wall (72) and an inner circumferential cover wall (74). The cap-shaped plate (70), the wall of the outer circumferential cap (72) and the inner circumferential wall (74) are sized so that when the sealing cap (66) is rotated about the joint (68) and pressed on the dispensing cover (22), a frictional fit is formed between the sealing cap (66) and the dispensing cap (22), thereby retaining it in a closed position. According to the embodiments described in Figure 5, the sealing cap (66) is also provided with an upper circumferential skirt (76), which extends outwardly from the flange (26) in the same direction as the upper portion in mouthpiece shape (24). Desirably, the upper circumferential skirt (76) is dimensioned to engage a, and to form a frictional fit between itself and at least a portion of the wall of the outer circumferential cover (72). Again, according to the embodiment described in Figure 5, the lid-shaped plate (70) is provided with an inner circumferential cover wall (74) which is sized, desirably, so as to form an adjustment by friction between at least a portion of the wall of the inner circumferential cover (74) and at least a portion of the nozzle-shaped upper portion (24) of the dispensing cover (22) when the sealing cap (56) is rotated and closed on the sealing cap (22). According to this embodiment, the upper portion in the form of a nozzle (24) that extends upwards from the rim (26), engages within a cavity of the upper part in the form of a nozzle (78). According to particular preferred embodiments, the dimensions of the wall of the circumferential layer (74) and the dimensions of the upper portion in the form of a nozzle (24), are selected so as to form a frictional fit, desirably a liquid-tight seal, when the sealing cap (66) is engaged on the distribution cover (22). That provides a substantial likelihood of loss of the liquid composition contained within the compressible bottle (10). To facilitate the opening of the cover plate (70), a push tab (80) is provided on at least one edge of the outer circumferential wall (72). The push tab (80) facilitates the fastening of the cover plate (70) and its removal from the dispensing cover (22).

Turning now to Figure 6, it describes a further additional embodiment of the invention, which shares common elements with those of Figure 5. These are indicated in Figure 6. According to the modality described in Figure 6, a "plug type" distribution cover is disclosed which includes an inner circumferential skirt (34), which is dimensioned to provide a liquid-tight friction fit between the outer wall (36) of the inner circumferential skirt ( 34), and with the neck (16) of the compressible nozzle (10). Although the embodiments of Figures 5 and 6 have illustrated a recoil type cap, it was also contemplated that other types of cap constructions may be used in conjunction with the improved dispensing caps according to the present invention. Those, of course, include suitably configured, removable covers, which include a circumferential skirt having coupling threads (not shown), but which would be adapted to engage the threads of the cover (82) illustrated in Figure 1. Turning now to Figure 7, there is described a front view of a nozzle-shaped upper portion (24) of a dispensing cap according to the invention, which provides improved foaming properties to the liquid compositions that are being distributed from it. According to this embodiment, the discharge orifice (2B) is comprised of a plurality of small holes with straight edges, here described as four holes of square shape with an approximately equal size and distributed in a row uniformly. Similarly, in Figure 8 there is described a front view of a further embodiment of a nozzle-shaped upper portion (24) of an improved dispensing cap (22) according to the invention, where, however, the orifice of discharge is comprised of four individual holes, generally circular, arranged in a group or set. According to the embodiments illustrated in Figure 7 and Figure 8, the discharge orifice (28) greatly facilitates the induction of foaming of a liquid composition that is intended to provide such an effect. These discharge orifices (28) act to break and distribute the stream of the composition leaving the mixing chamber (50) of the upper portion in the form of nozzle (24). Its reasoned sizing, as well as the placement, can also be used to help the flow direction that leaves the distribution cover. For example, as shown in Figure 7, four individual square-shaped holes arranged in a row will provide a generally flat or linear distribution pattern of the composition being distributed. Alternatively, the discharge orifices (28) as illustrated in Figure 8, comprised of individual circular orifices arranged in a set or group will tend to provide a more circular distribution pattern of the composition being dispensed from the cover. distribution (22). With respect now to Figure 9, there is illustrated a cross-sectional view of one more embodiment of a dispensing cap according to the present invention. This embodiment is of the "plug type" and shares many of the common characteristics of the embodiment illustrated in Figure 6. With respect to Figure 9, it also illustrates a cavity (84), which is integrated to the surface inside (86) of the mixing chamber (50). The cavity (84) desirably has a portion which extends from the air flow channel (46), and therefore extends towards the discharge orifice (28). The presence of that cavity (84) facilitates the improved mixing of the air and the liquid composition in the mixing chamber (50). Desirably, the width of the cavity (84) increases as it extends from the air flow channel (46) to the discharge orifice (28), which helps ensure that the spray type distribution mode improves. Figure 10 illustrates a detailed cross-sectional view of a dispensing lid (22) according to the present invention, and corresponding to the embodiment illustrated in Figure 9. Described in Figure 9, there is again a view in cross section of a nozzle-shaped upper portion (24) taken along the reference lines RR as shown generally in Figure 9. The nozzle-shaped upper portion (24) includes an orifice (55) inside which is placed the proximal end portion of the dip tube (40), and a flow channel (46). As discussed with reference to Figure 9, it also has a cavity (88) whose lateral boundaries are indicated by the two dotted lines in Figure 10, with the cavity being within those dotted lines. It should also be understood that the cavity (88) does not coincide with the reference lines R-R, but is described as a projection thereon. Furthermore it should be understood that as in Figures 2, 3 and 4, the air flow channel (46) has a dimension at the top, which can be as little as approximately 1 millimeter, or which can be extended to all length of the proximal end portion (42) of the dip tube (40) which is inserted in the projection (38) and the upper portion in the form of a nozzle (24), or may even be longer. As in Figure 2, the air flow channel (46) in Figure 10 has a cross-sectional area (56), and each has open ends (54), which are in contact with the outer wall (52). ) of the dip tube (40) and again, the interior of the dip tube (50) also has a cross sectional area (58). Again, it should be understood that the cross-sectional area (56) of the air flow channel (46) must be equal to, but desirably less than, the cross-sectional area of the interior (58) of the dip tube (40) . Desirably, the cross-sectional area (56) is less than 80% of the cross-sectional area of the interior of the dip tube (58), still more desirably less than 50%, but still more desirable , is not greater than 30% of the cross-sectional area of the interior (58) of the dip tube (40). Although described in terms of the presently preferred embodiments, it should be understood that the present description should be interpreted by way of illustration, and not by way of limitation, and that various modifications and alterations apparent to one skilled in the art can be produced without departing of the scope and spirit of the present invention. It is noted that in relation to this date, the best method known by the applicant to carry out the aforementioned invention, is the conventional one for the manufacture of the objects to which it relates.
