Description

Technical Field

[0001] This report describes a patent application proposing a device for liquid packaging that can be attached to a bottle storing liquid, allowing the liquid to be dispensed in the form of a spray or jet. This device for liquid packaging can be used with bottles of various shapes and capacities, including but not limited to use in beauty salons, hair salons, and similar locations. Foreword

[0002] This patent application relates to a device for use in liquid packaging, the innovation of which is that the direction of the spray (or jet) flow can be adjusted, allowing not only forward spraying as in the conventional manner, but also spraying (or jetting) backward (i.e., towards the user). Another innovation of the device for use in liquid packaging proposed herein is that it includes a locking insert that can keep the drive trigger locked to prevent accidental activation, for example, when the liquid packaging (and associated device) is in transit. Existing technology

[0003] As is well known, there are various devices used for liquid packaging, which are typically used to attach to bottles containing a certain volume of liquid (such as water or other liquids) so that the stored liquid can be used in the form of spray or even jet.

[0004] This device for liquid packaging has a variety of uses, including in the field of horticulture (as a way to apply small doses of water to delicate plants or flowers), in home cleaning procedures (as a way to apply various products used in such activities), and in beauty salons, barbershops and similar establishments.

[0005] Generally, the device for liquid packaging suggested in this article is typically defined as a plastic device manufactured using an injection molding process, containing a small, hand-operated pump. Through a series of triggers, this device drives a mechanism to extract liquid from the packaging or bottle and deliver it under pressure to a nozzle, where the liquid is expelled as a spray or jet.

[0006] This type of device for liquid packaging is also widely used in other fields. Examples of prior art can be found in the following patent documents: PI0912446-2, filed on July 8, 2009, entitled "Liquid Sprayer"; BR132016029462-1, filed on December 15, 2016, entitled "An Improved Universal Liquid Sprayer"; and BR202021009292-6, filed on May 13, 2021, entitled "A Structure for Water Storage and Concentrated Product Sprayer, Having a Mechanism for Diluting Concentrated Products in Water". Problems with existing technology

[0007] The devices disclosed in the three prior art documents mentioned above are merely examples, each with its own unique design. Among them, the device proposed in patent document PI0912446-2 belongs to a relatively conventional structure, and its claims mainly define the specific structural design details.

[0008] On the other hand, a device proposed in patent document BR132016029462-1 has a resistance heating component installed at the bottom of the bottle or packaging container to heat the liquid contained in the bottle or packaging container.

[0009] Finally, regarding patent document BR202021009292-6, it discloses a device for use with a bottle or packaging container. The bottle or packaging container has two separate chambers, each containing two different liquids. When the trigger of the device is manually operated, the device sprays a mist of liquid (or a stream of liquid) containing both liquids, causing them to mix and dilute during the spraying process.

[0010] While the three devices described above each possess different technical characteristics, they all share a common limitation: the spray (or the liquid stream formed according to the selected spray pattern) is always directed forward. Therefore, for example, the liquid inside the bottle or packaging container cannot be directly sprayed onto the user's body.

[0011] In other words, the spray or jet stream generated by the existing technology device is always forward.

[0012] Another limiting aspect of the device described in the aforementioned prior art documents is that, under certain circumstances, its trigger may be accidentally activated, which could lead to the accidental and unnecessary release of some liquid from the connected bottle.

[0013] Such accidents can occur if liquid devices / packaging components are handled carelessly during transport or improperly when stored in shipping boxes, bags, or similar containers. Purpose of the invention

[0014] In view of the inconveniences of existing devices, the device for liquid packaging proposed herein was developed. The device is innovative in two aspects that are not noticed by any currently known solutions, including: a) the design and assembly of the nozzle, the direction of which can be adjusted so that the spray can occur forward as usual, but can also be adjusted to occur in the opposite direction, i.e., towards the user's own direction; b) providing a locking insert that, when used with the device's trigger, blocks the trigger, thus preventing unwanted or accidental activation. Advantages of the present invention

[0015] The proposed device, because the nozzle direction can be adjusted according to the desired direction, can produce forward and backward sprays (or jets) facing the user, filling a gap in currently known designs. Another advantage is that the locking insert of the proposed device design can prevent the trigger from being activated, thus preventing the trigger from being improperly or accidentally activated when used in the device. Summary of the Invention

[0016] The proposed liquid packaging device (hereinafter referred to as the "device") includes a housing with a vertical opening through which a trigger extends. The trigger is used to activate an internal pumping system. The device is also equipped with a locking insert that, when the trigger is pressed, fits onto the trigger within the vertical opening, thereby preventing the trigger from popping out. This locking insert ensures that the trigger remains in the pressed position until it is removed, thus preventing the trigger from being accidentally or unintentionally activated, and consequently preventing any leakage of liquid stored in the bottle or package.

[0017] The device proposed in this suggestion has a nozzle on the top of its housing, which is mounted on a rotating base, and the position of the nozzle can be changed between forward and backward relative to its trigger. Brief description of the attached diagram

Invention Details

[0025] As shown in the figure above, the device (1) has a housing (2) with a vertical opening (3) on it. A trigger (4) extends from the opening to activate the internal pumping system (5). The device has a locking insert (6) that, when pressed, fits onto the trigger (4) and is embedded in the vertical opening (3), thus preventing the trigger (4) from accidentally popping out. It should be noted that although the internal pumping system (5) is schematically represented by a dashed box in the figure, it is not the subject matter claimed by this invention, as it is already included in the prior art and therefore does not require further detailed description.

[0026] There is a nozzle (7) in the upper part of the outer casing (2) opposite to the diameter of the trigger (4), which can generate a spray or jet by compressing the trigger (4).

[0027] The locking insert (6) ensures that the trigger (4) remains in the lowered position until it is removed, thereby preventing the trigger (4) from being accidentally or accidentally triggered.

[0028] The proposed device (1) in its main model (as shown in Figures 1, 2, 3, 15, 16, 17 and 18) and its alternative version (labeled (1A)) (as shown in Figures 4, 5 and 6) has a rotating base (9) on the upper part (8) of the housing (2) where the nozzle (7) is mounted, allowing the nozzle (7) to change position between forward and backward relative to the trigger (4) of the device (1), as specifically shown in Figures 2 and 6 by the bidirectional arrows “A”-“B”.

[0029] The locking insert (6) is made of an integral part (10) manufactured by injection molding, having a front wall (11) from which a handle (12) extends. The surface (13) of the front wall (11) is curved in both the vertical (V) and horizontal (H) directions to match the vertical (V) and horizontal (H) curvature of the surface (14) of the outer wall (15) of the housing (2), as is the case for the alternative version of the housing (2A) of the device (1A).

[0030] The integral component (10) has a sidewall (16) with a straight upper horizontal edge (17) and an arc-shaped lower edge (18), and the upper surface (19) of the integral component (10) is partially formed by triangular horizontal walls (20) that start from the upper edge (21) of the front wall (11) and extend toward the end of the sidewall (16).

[0031] At the end of each sidewall (16) there is an outwardly protruding rectangular protrusion (22), which acts as a locking mechanism to lock the locking plug (6) to the internal structural walls (23) on both sides of the vertical opening (3) of the housing (2), and the same applies to the housing (2A), an alternative version of the device (1A).

[0032] In the area of ​​the upper edge (21) of the front wall (11), there is also an upward-facing central rectangular protrusion (24) that locks the locking insert (6) to the internal structural wall (23) located at the upper edge (25) of the vertical opening (3) of the housing (2).

[0033] The inner surface (26) of the front wall (11) of the locking insert (6) has two vertical wall segments (27) for structural reinforcement of the integral component (10).

[0034] The device (1) proposed herein, whether its main model or its alternative model (1A), is connected to a liquid storage bottle (28), which is indicated by a dashed line, because its specific model or shape is not the subject matter claimed in this patent application.
