The object of the present application is to register a protector for containers.
More specifically, the invention proposes the development of a protector for containers, intended to be coupled to cylindrical containers that include a rivet that protrudes in the upper portion of the very container, comprising an upper lid to cover the upper face of the container and a lower ring that can be coupled to the side wall of the container, such that the lower ring is able to rotate with respect to the container.
The arrangement of protectors for containers for hygienic purposes, which are essentially comprised of an upper lid that is articulated by means of a hinged region to a lower ring that can be coupled to the container, is well known in the state of the art, these protectors being especially suitable for can-type containers. Examples of this type of protectors are described in Spanish patents held by the same applicant no. ES 1071303, ES 1072031.
Although the protectors described in the previous patents satisfactorily fulfil the hygienic purpose, the market has increasingly new needs, among which include the possibility of being able to place the protectors in alignment with respect to a mark or point of the container in order to improve the presence of the display of the containers when they are shown, for example, for retail sale, where the visual appearance of the assembly of the containers (the display of the product brand or logo, promotions) is a point of great interest for distribution companies.
Therefore, it is necessary that the protector for containers be able to be simply and easily redirected to the consumer, without implying constructive complexity of the protector.
In addition, the applicant is currently unaware of the existence of an invention having all the characteristics described herein.
The present invention has been developed with the aim of providing a protector for containers that constitutes a novelty within the field of application, and solves the disadvantages mentioned above while also contributing other additional advantages, which will become evident from the description provided below.
Therefore, an object of the present invention is to provide a protector for containers, intended to be coupled to cylindrical containers that include a rivet that protrudes in the upper portion of the very container, comprising an upper lid to cover the upper face of the container and a lower ring that can be coupled to the side wall of the container, the upper lid and the lower ring being attached to each other in a hinged way.
In particular, the invention is characterised by the fact that the lower ring includes in a point close to the upper flange thereof a plurality of locking tabs that are separated from each other, which protrude from an interior face of the lower ring in an upwards direction and along the entire perimeter of the lower ring, said locking tabs having an angle of inclination with respect to a vertical portion of the lower ring, said locking tabs being designed to hold the side wall of the container and abut under the rivet present in the upper part of the container, and wherein the upper lid includes at least a negative portion that protrudes from an interior face of a perimeter flange, which is fastened to the locking tabs in a closed state of the upper lid with respect to the lower ring.
In one embodiment, at least said negative portion that protrudes from the interior face of a perimeter flange is facing and in contact with the locking tabs in a closed state of the upper lid with respect to the lower ring.
In an alternative embodiment, it comprises a plurality of negative portions that protrude from the interior face of a perimeter flange, which are facing and in contact with the locking tabs in a closed state of the upper lid with respect to the lower ring.
In an alternative embodiment, the protector for containers comprises a plurality of negative portions that protrude from the interior face of a perimeter flange, which occupy the free space between the locking tabs in a closed state of the upper lid with respect to the lower ring.
There is also the possibility that the invention has a configuration of negative portions that is a combination of the embodiments described previously.
Said lower ring further includes a chamfered lower extension that facilitates the insertion of the lower ring in the container since it enables possible variations of centring between the protector and the container at the time of assembly to be absorbed.
Thanks to these characteristics, in addition to the hygienic advantages that it entails for a user, the outlet area of the container through which a beverage to be consumed, for example, exits facilitates the rotation of the assembly of the protector with respect to the container, which enables the “front position” of the protector to be aligned with respect to a specific point of the rest of the container. Furthermore, this structural configuration prevents the protector from being extracted from the container in an undesired way. Furthermore, the presence of the locking tabs reduces the deformation that the rest of the lower ring may undergo during the assembly of the protector in a corresponding container.
According to another aspect of the invention, each locking tab has in a lower region a depression with a material thickness, which enables a degree of flexibility thereof, which facilitates the placement of the protector in the container during an assembly operation, thereby optimising an assembly process, as well as facilitating the action of rotating the protector with respect to the container on which it is assembled.
Preferably, the lower ring has a plurality of partitions that protrude from the exterior face thereof, thereby providing a better holding surface of the protector for the user in order to facilitate the rotation thereof if required.
Also preferably, a side wall of the upper lid has a plurality of partitions.
Advantageously, the partitions present in the upper lid are complementary in shape and size with respect to the partitions present in the lower ring.
Other characteristics and advantages of the protector for containers, object of the present invention, will become clear in light of the description of a preferred, though non-exclusive, embodiment, which, by way of a non-limiting example, is illustrated in the accompanying drawings, wherein:
In view of the aforementioned figures and, in accordance with the numbering adopted, an example of a preferred embodiment of the invention can be observed therein, which comprises the parts and elements indicated and described in detail below.
As can be seen in the two embodiments shown in
It should be mentioned that this protector has a dual function as a watertight seal and a sealing shutter thanks to the structural configuration of the protector shown in
The upper lid includes at least one negative portion (16) (first embodiment shown in
The embodiment shown in
To enable the rotation of the protector with respect to the container, the lower ring (2) includes in a point close to the upper flange thereof a plurality of locking tabs (4) that are separated from each other, which protrude from an interior face of the lower ring (2) in an upwards direction and along the entire perimeter of the lower ring (2), said locking tabs having an angle of inclination with respect to a vertical portion (5) of the lower ring, said locking tabs (4) being designed to hold the side wall of the container (E) and abut under the rivet (10) present in the upper part of the container (E).
Advantageously, each locking tab (4) has in a lower region a depression (40) with a material thickness, as can be seen in more detail in
To facilitate the hold for rotating the upper lid (1) and positioning it in a specific way, the lower ring (2) and the side wall of the upper lid (1) have a plurality of partitions (6, 7) that protrude from the respective exterior faces thereof.
It should be mentioned that the partitions (6) present in the upper lid (1) are complementary in shape and size with respect to the partitions (7) present in the lower ring (2).
Furthermore, the protector includes a guarantee seal that is made up of a pair of protrusions (8) that protrude outwardly from the lower ring and are inserted in corresponding windows (14) in a state prior to a first use of the container. In the case that a user separates the upper lid (1) from the lower ring (2), said protrusions (8) will break a fragile region (9). Thus, it enables the user to know whether the container has been previously handled.
The upper lid (1) preferably includes a housing (11) that is made up of a centred protruding portion, which defines a space for housing additional objects, such as an envelope or pouch that contains some food ingredient or cutlery or similar. As can be seen, the upper part of the housing has a flat surface (12), which facilitates the display of publications on said surface which can be easily read by the user.
To help the user to open the upper lid (1), a tongue (13) is provided which is located in the front part of the upper lid (1), as shown in
The lower ring further includes a chamfered lower extension (15) intended to facilitate the insertion of the lower ring in the container.
