Description

DISPENSING CONTAINER

Description

The present invention relates to a dispensing container, and in particular to a container of the type comprising a main bottle receiving a fluid product to be dispensed and a metering receptacle connected to the main bottle by a duct, in which the main bottle is apt to be deformed to cause the inflow of the fluid product through the duct and into the metering receptacle.

Several types of the hereto-introduced container are known. In particular, EP 0 010 965 to Bettix Limited discloses a deformable container, in which a main bottle for a liquid and a metering receptacle are arranged side-by-side and are mutually connected by a duct having a sinuous course. By pressing onto the walls of the main bottle, the user makes the liquid inflow from such bottle into the duct, and from the latter into the metering receptacle. Then the liquid is dispensed outwardly through a top opening of the metering receptacle. The present invention stems from the observation that the known-art container just described entails the drawback that the liquid coming from the main bottle is violently expressed into the metering receptacle and tends to directly outpour through the top opening of the latter. This is due to the fact that the main bottle has to be pressed vehemently in order to make the liquid inflow from the bottle itself into the metering receptacle, and from the fact that the cap usually closing the top opening of the metering receptacle has to be removed or at least loosened in order to allow the outlet of air required for liquid inlet.

Hence, the known-art containers described hereto can be cumbersome and less than practical to use. Moreover, they can cause an undesired waste of the product contained therein. Furthermore - and above all - such known-art containers cause a difficult metering of the product.

Hence, the technical problem underlying the present invention is that of providing a dispensing container allowing to overcome the drawbacks mentioned above with reference to the known art. Such a problem is solved by a container according to claim 1.

Preferred features of the present invention reside in the dependant claims thereof.

The present invention provides some relevant advantages. The main advantage lies in the fact that the specific shape of the duct lumen near the inlet port of the fluid into the metering receptacle reduces the fluid outflow rate, fostering an even outflow of the fluid into the metering receptacle and thereby avoiding outpours thereof outside of the container. This also prevents squirting from the container and facilitates the metering steps.

Hence, the container of the invention is convenient and practical to use. Moreover, it avoids any waste of the fluid product contained therein. Other advantages, features and the operation steps of the present invention will be made apparent in the following detailed description of some embodiments thereof, given by way of examples and not for limitative purposes. It will be made reference to the figures of the annexed drawings, wherein:

Referring initially to Figure 1 , a dispensing container according to the present invention is generally indicated by 1. In the present embodiment, the container 1 is meant to contain a fluid product for house-cleaning.

The container 1 mainly comprises: a main bottle 2 for a fluid, apt to receive the fluid product to be dispensed; a metering receptacle 3, located above the main bottle 2 and apt to allow a metered outwardly dispensing of the product; and a duct 4, communicating the bottle 2 with the metering receptacle 3. Each of such components will be described in greater detail in the following, with reference to two specific embodiments of the invention.

As best seen in Figure 2, the main bottle 2 has a base, or bottom, 21 and a sidewall 22, the latter shaped so as to have sides 23 and 24 having a sinuous contour. Along the side 24 of the container 2 there extends also the duct 4, which therefore develops according to the same sinuous contour.

In the present embodiment, the main bottle 2 has a cross section of elongated shape. Within the main bottle 2 a gripping seat 5 is obtained, just for allowing a user's gripping the container 1.

The bottle 2 has an outlet port, denoted by 6, for the fluid product, located at the side 24 of the bottle 2 itself and near or adjacent to the bottom 21 , substantially at the same level of the latter. As best seen in Figure 3, the outlet port 6 has a substantially elongated shape, with a greater transverse dimension 61 thereof located substantially parallel to the bottom 21 of the main bottle 2. In the present embodiment such an outlet port 6 is substantially oval or elliptical.

Further referring to Figure 2, the metering receptacle 3 has a capacity substantially lower with respect to the main bottle 2, and it is meant, as mentioned above, to meter the fluid product contained in the container 1. For this purpose, the metering receptacle 3 bears, at a sidewall 31 thereof, graduation marks 32 apt to allow an accurate metering.

The metering receptacle 3 is located substantially longitudinally aligned to the main bottle 2, and it also has a cross section of elongated shape and tilted sides, the latter indicated by 33 and 34, respectively, corresponding to the sides 23 and 24 of the main bottle 2. The duct 4 also extends along the side 34 of the metering receptacle 3, partly following its contour.

The metering receptacle 3 is connected to the main bottle 2 by a vertical channel 13 substantially centered with respect to the longitudinal axis of the container 1. This vertical channel 13 is used by the manufacturer solely to fill the container 1 , and in particular the main bottle 2 thereof. Upon attaining the initial filling of the bottle 2, the channel 13 is sealed by the same manufacturer with a cap, so as not to be subsequently re-openable by the end user. The metering receptacle 3 further comprises a top opening 8 for outwardly dispensing the fluid product. In particular, such opening 8 of the metering receptacle 3 opens on a neck 9 of the container 1 having an external thread apt to allow the closure thereof by a cap 10, the latter being shown by way of example in Figure 1.

As it is shown, e.g., in Figures 4A and 4B, the duct 4 has an internal lumen 12 connecting the outlet port 6 of the main bottle 2 to an inlet port 7 or 70 of the metering receptacle 3, so as to allow the transit of the fluid to be dispensed from the former to the latter.

At the portion of the duct 4 ending into the metering receptacle 3, the container 1 is susceptible of various alternative embodiments.

A first embodiment is shown in Figures 4A and 5A. Referring to these latter figures, as already mentioned above the metering receptacle 3 comprises a port for inletting the fluid product thereinto, in this case denoted by 7. This inlet port 7 is located at a top portion of the vessel 3, and in particular at the tilted side 34 thereof, hence substantially at the same side of the outlet port 6 of the bottle 2. The overall arrangement is such that, by virtue of the tilting of the side 34, the inlet port 7 substantially faces the bottom 21 of the container 1.

As it is shown in greater detail in Figure 5A, also the inlet port 7 has a substantially elongated shape and it is located with a greater transverse dimension 71 thereof substantially parallel to the bottom 21 of the main bottle 2. In particular, in the present embodiment such inlet port 7 is substantially elliptical or oval.

As it is shown always in Figures 4A and 5A, in the present embodiment the metering receptacle 3 internally has a deviation member 11, extending thereinto from the internal face of the sidewall 31. As it will be detailed later on, the deviation member 11 is apt to deviate the flow of product crossing the port 7 toward the bottom of the metering receptacle 3, i.e. toward the bottom 21 of the container 1 , so as to prevent a product outpouring from the top opening 8.

More precisely, the deviation member 11 is located at the inlet port 7, and in particular thereabove. In the present embodiment, the deviation member 11 is in form of a flap and it also implements a squirt guard member.

At the inlet port 7 of the metering receptacle 3, the lumen 12 comprises an end portion 121 having a cross section increasing toward the inlet port 7 itself.

In the present embodiment, such an end portion 121 has a substantially frustum-of- cone -shaped development. The cross section of the portion 121 matches that of the inlet port 7, hence having an analogous substantially elongated shape, and in particular elliptical or oval, and an analogous arrangement with a greater cross dimension substantially parallel to the bottom 21 of the container 1.

Of course, even near the outlet port 6 of the bottle 2 the internal lumen 12 of the duct 4 has a portion having a cross section of shape and arrangement analogous to those of the outlet port 6 itself. A second embodiment of the container 1 , and especially of the end portion of the duct 4 ending into the metering receptacle 3, will hereinafter be described with reference to Figures 4B and 5B and in connection to the sole aspects differentiating such second embodiment from the first one. In such second embodiment, the metering receptacle 3 comprises an inlet port, in this case indicated by 70, located also in this case at the tilted side 34 of the receptacle 3 itself. Hence, in this case as well, the overall arrangement is such that by virtue of the tilting of the side 34 the inlet port 70 substantially faces the bottom 21 of the container 1. As it is shown in greater detail in Figure 5B, also the inlet port 70 has a substantially elongated shape and is located with a greater transverse dimension 710 thereof substantially parallel to the bottom 21 of the main bottle 2. In particular, in the present embodiment this inlet port 70 is substantially half-ellipse- or half-moon- shaped. As it is shown always in Figures 4B and 5B, the lumen 12 comprises, at the inlet port 70 of the metering receptacle 3, an end portion, in this case indicated by 1210, having a substantially descending development tilted toward the bottom 21 of the container 1 , therefore extending substantially bottomwise.

The cross section of the portion 1210 matches that of the inlet port 70, hence having an analogous substantially half-ellipse or half-moon shape, and an analogous arrangement with a greater transverse dimension substantially parallel to the bottom 21 of the container 1.

The end portion 1210 has a cross section increasing toward the inlet port 70. In particular, in the present embodiment the end portion 1210 has, at a bottom wall 1211 thereof, a substantially frustum-of-cone -shaped development having an elliptical base, so as to implement the abovementioned half-ellipse or half-moon shape of the cross section.

The wall of the side 34 arranged above the inlet port 70 has an appendix 1212 extending substantially at the top mouthpiece of the port 70 itself. This appendix 1212 has a substantially vertical development and serves as a flow deviation member, analogously to the flap 11 of the preceding embodiment. In particular, the appendix 1212 deviates the flow of product downwards, i.e. toward the bottom of the metering receptacle 3 (and therefore toward the bottom 21 of the container 1).

Returning now to the general description of the container 1 , in the present embodiment the lumen 12 has a substantially circular cross section along the entire length of the duct 4, said section assuming an elongated section merely in the end parts at the outlet port 6 and inlet port 7, 70.

The container 1 , and in particular the main bottle 2 thereof, is made of a material having an elastic deformability such as to allow the container 2 to be deformed to cause the fluid product to inflow through the duct 4 and into the metering receptacle 3. Moreover, the container 1 may be piece-formed by a blow-molding method.

The operation modes of the container 1 will be illustrated hereinafter with reference to the hereto-introduced figures.

When a user wishes to dispense the fluid product contained in the container 1 , he/she squeezes the sidewall 22 of the main bottle 2. Such a squeezing reduces the internal volume of the latter and expresses the product through the duct 4 and therefrom into the metering receptacle 3. It will be appreciated that, as mentioned above, the specific shape having an increasing cross section of the end portion 121 or 1210 of the lumen 12 fosters an even outletting of the product, preventing outpourings of the latter from the container 1 and reducing or eliminating squirting. In particular, the hereto-described specific shape and arrangement of the lumen 12, in particular in the second embodiment illustrated with reference to Figures 4B and 5B, causes a fan-shaped inflow of the product into the metering receptacle 3.

Moreover, the presence of the deviation member 11 or 1212 prevents, under any circumstance, that the product, turbulently flowing out from the duct 4 into the metering receptacle 3, directly outpours from the container 1 through the top opening 8. In fact, this member 11 or 1212 works as a barrier for the fluid product, deviating the latter downwards and letting it flow toward the bottom of the metering receptacle.

In the second embodiment illustrated above, this latter advantage is obtained also by virtue of the descending course of the end portion 1210 of the lumen 12. In fact, such a course, jointly to the fact that the inlet port 7, 70 substantially faces the bottom 21 of the container 1 , allows the flow of product to have a substantially downwardly oriented direction of inlet into the metering receptacle 3.

Besides, these advantages are important since a user is hardly capable of accurately gauging the force required to make the product evenly inflow from the bottle 2 into the metering receptacle 3 - also since such force should vary according to the amount of fluid remaining into the bottle 2 itself as well - entailing that often the fluid product receives a thrust markedly greater than the required one.

Moreover, the elongated shape and the specific arrangement of the cross section of the outlet port 6 and of the lumen portion 12 near such port 6 allows the product to be dispensable down to the total emptying of the bottle 2, preventing unused product from remaining onto the bottom 21 of the container 1.

Upon transferring the fluid product from the bottle 2 to the metering receptacle 3, the user may dispense it in the desired dose, also with the aid of the gradation marks 32.

It will be understood that the present invention is susceptible of several forms and embodiments alternative to the hereto-described ones, above all concerning the inlet of the metering receptacle and the duct portion adjacent thereto.

For example, the end portion of the duct internal lumen arranged near to the inlet port of the metering receptacle may have a substantially frustum-of-pyramid development instead of a frustum-of-cone one.

The present invention has been hereto described with reference to preferred embodiments thereof. It is understood that other embodiments might exist, all falling within the concept of the same invention, and all comprised within the protective scope of the claims hereinafter.
