OBJECT OF THE INVENTION
[0001] The present invention relates to a stop-like device or individual part that is used
to close food cans that are open. This stop is an element that can be adapted to any
type of food packaging and one of the advantages thereof is that it is reusable.
[0002] The general field of application of the present invention is the industry for producing
plastic parts or elements, and particularly, this invention is also related to the
industrial sector for producing packaging or lids for canned food products, in the
same way that it is intended for domestic use or industrial use related to providing
restoration services.
[0003] The object of the invention is to introduce a solution that enables food cans to
be able to be closed, given that once this type of packaging is opened, it cannot
be closed, which thus leads to the oxidisation or degradation of the characteristics
of the food product, even if it is inside a refrigerator, just as it enables preventing
accidental harm caused by unintentional cuts.
BACKGROUND
[0004] It is common knowledge that not all food maintains the optimal consumption conditions
thereof for a prolonged amount of time. To solve this problem, the solution of food
cans arose in the 19th century where certain types of elements were protected inside
the packaging, which has logically evolved from the original packaging made of glass
sealed with lead to the current solutions consisting of metal containers, the most
common ones being made from tin and aluminium depending on the area and the product
to be preserved.
[0005] All the types of known cans enable the food product to be preserved for a prolonged
amount of time, but they only protect said product as long as the can is closed. Once
a user opens the can, the food is irremediably subjected to degradation. Generally,
in order to solve this problem, one attempts to cover the can again with the broken
part, where one part continues to remain open, or a plastic film is placed thereon
which is a weak film and is susceptible to being easily broken. This is combined with
the insertion of the can into a refrigerator, which makes it so the degradation process
is slower, but which may create another type of disadvantage such as the refrigerator
becoming impregnated with the smell of the food, it can get dirty or other commonly
derived disadvantages.
[0006] Thus, it is evident that a problem arises from preserving a food product protected
inside a food can once said can is opened.
[0007] To this end, it is worth noting that, like in all the application fields, solutions
have been created which intend to solve this problem. We will highlight certain registrations
related to the present invention that have differentiated structures. Regarding beverage
cans, which are a type that the present invention is not preferably intended for,
solutions have been developed such as the one disclosed in document
ES2187937 where the opening of the can is reinforced with an annular bead with flanges which
enables the coupling of a complementary closing lid. Document
ES1069073U is also known, intended for cans with a particularly cylindrical configuration and
the content of which is a liquid, which discloses a complementary lid with an opening
that can be opened and closed given that it is an element able to be articulated,
and where said lid is coupled to the open face of the cylindrical can. Document
ES1023228U is also notable, wherein a closing device for beverage cans is disclosed that can
be coupled by means of a lever to the opening of said type of cylindrical cans. Finally,
that which is disclosed in document
ES1048748U is notable; it describes a closing lid for a can which, although preferably intended
for cans with a cylindrical configuration, can be modified for any type of configuration.
It consists of a lid that is coupled and clipped on the rims of the can, closes the
entire open surface, and further comprises a tab or ring that enables it to be pulled
in order to facilitate the opening of said lid.
[0008] As can be seen, all these types of solutions are based on added lids or surfaces
that are placed on all the open surface of the can, which makes it so the problem
of the closing is solved; however, to do so it requires precisely covering the entire
surface with another independent lid.
[0009] Taking into account the solutions existing in the state of the art, it can be seen
that there is no known solution that closes food cans where one of the faces thereof
is opened but not removed in its entirety; therefore, it does not require a new lid
to be placed, but rather ensure that said open face returns to the position thereof
such that it closes the assembly of the can again. In order to solve this problem,
which is present in practically all the different types of food cans, preferably food
cans not intended for beverages or liquid products, but rather for solid foods, the
present invention is developed. This invention introduces a simple device into this
sector that can be coupled on the rims of the can and press on the open face so that
it closes the assembly of the food can.
[0010] It can thus be noted that the present invention has a series of advantages, such
as preventing or reducing the oxidation or degradation of the product, which among
other things creates a mixture of smells in the refrigerator; it is used to prevent
accidental harm from unintentional cuts; it contributes to savings in the home as
it also does with the environment when we avoid throwing away a number of cans because
the food content thereof has gone bad too quickly since they were not properly closed;
it prevents it from splashing when an open, poorly closed can is taken out, for example,
a can of squid in black ink sauce where the lid comes off like a spring, coming up
and splashing everything nearby.
[0011] Thus, the present invention resolves the technical problem of ensuring the closing
of a food can once opened without needing to clip or place a new lid on the open part
of said food can, thereby ensuring that the product is conserved in optimal conditions
for a longer amount of time and given the previously explained advantages.
DESCRIPTION OF THE INVENTION
[0012] The present invention describes a stop-like device or individual part that is used
to ensure that a food can be closed again, said device being able to be reused, and
with which this device resolves this problem without needing to use additional complex
closing systems or the need to have to cover the entire can with a new cover.
[0013] Taking into account these aspects, the device object of the invention is a part that
clips on the point of the open circumference of the can, and which, by means of a
fastening tab, enables the open lid of the can to be pressed so that it is in a closed
position. By means of the use of a plurality of devices along the circumference, it
is ensured that the entirety of the lid of the can remains closed, without needing
to use a new cover.
[0014] To do so, the device is an element of a preferably plastic nature, which has a transverse
cross section with an inverted U-shaped profile, where a ridge projects from one side
and a fastening tab projects of the other side of each of the facing walls thereof.
The ridge is useful in that it enables the user to be able to press it for correct
clipping inside the perimeter rim of the can, and also enabling the removal thereof;
while the fastening tab has the feature of pushing and ensuring the position of the
lid of the can so that the assembly remains covered.
[0015] Entering into more detail, the inverted U-shaped profile is comprised of two walls
facing each other, an inner wall and an outer wall, joined by an upper edge. At least
one surface slit can be arranged in the outer wall, the function of which is to enable
the action of clipping and removing the device to be more comfortable and safer, and
so that the device does not interfere with the tab of the lid of the can. The two
walls do not necessarily have to have the same height, in fact, the height of the
outer wall can be, for example, greater than that of the inner wall.
[0016] A ridge projects from the free end of the outer wall, preferably in a perpendicular
plane, the ridge being a bent projection along all the entire rim thereof that is
long enough so that a force can be exerted manually, like a lever, on the device.
A fastening tab projects from the free end of the inner wall, which is also preferably
in a perpendicular plane, which is a sheet which acts as a stop so that the lid of
the can remains fastened on the lower surface thereof and thus requires the lid of
the can to remain in a closed position.
[0017] Entering into a longitudinal configuration of the device, the surface of the fastening
tab can comprise at least one notch that functions as a handle, which, at the same
time that it continues to fasten the position of the lid of the food can, may have
that additional feature. Moreover, the device can adapt longitudinally to the circumference
of the can; therefore, the device can be linearly straight for straight rims, or it
can be curved for can configurations with curves, such that said curvature can have
different diameters being adjusted to different types of food cans that exist in any
grocery store in the world.
[0018] The device is intended to be made from a plastic material, and preferably it is intended
to be made from PVC, given that this material has the light flexibility needed for
the actions of clipping and removing the device from the rim of the can; however,
it also has enough rigidity for the lid of the can to be fastened in the required
position. Nevertheless, this term is not limiting, and the device can be made from
any other material that meets these two conditions.
[0019] Finally, the device is intended for relatively small dimensions, due to the fact
that the optimal closing of the lid of the open can requires a plurality of points
where the device must be indicated along the circumference thereof.
[0020] To this end, it is considered that the optimal range of length of the device is between
10 and 100 mm, where the width of the fastening tab is between 7 and 15 mm, the width
of the ridge between 2 and 7 mm, the width of the edge of the U-shaped profile between
1 and 5 mm, and the height of both walls of the U-shaped profile between 3 and 10
mm. Nevertheless, this term is not limiting, and any part of the device can have another
dimension, as long as it meets the proportional relationship with the remaining parts
of the device.
[0021] To complete the present description, and for the purpose of aiding in a better understanding
of the characteristics of the invention, a set of drawings is presented wherein, by
way of non-limiting examples, the following has been represented:
Figure 1 shows a transverse cross section of the device and how it is clipped or coupled
to the perimeter rim of the can, and how the device fastens the open lid of the can.
Figure 2 shows a front view of the device.
Figure 3 shows a top view of the device when it has a straight linear configuration.
Figure 4 shows a top view of the device when it has a curved linear configuration
and with a notch in the fastening overlap.
DESCRIPTION OF THE DRAWINGS
[0022] As seen in the set of figures, the closing device (2) for an open food can, according
to the previously described characteristics, is placed in the open circumference or
rim (11) of the food can and where the can (1) still has the lid (12) thereof which
has not been completely removed.
[0023] This device (2) is made from plastic material, preferably PVC, and has a transverse
cross section comprising a central inverted U-shaped profile (3) with an outer wall
(31) facing an inner wall (32) and both remaining joined by an edge (33). As seen
in Figure 1, the height of both walls does not need to be the same, and in fact, preferably,
the height of the outer wall (31) is greater than that of the inner wall (31), both
of them thus having different heights. As seen in that figure, the rim (11) remains
fitted by being clipped in the inverted U-shaped profile (3). A ridge (4) projects
from the free end of the outer wall (31), preferably in a perpendicular plane, which
has the function of reinforcing as well as enabling the user to use leverage to clip
or remove the device (2). A fastening tab (5) projects from the free end of the inner
wall (32), which is a sheet with a preferably larger dimension than that of the ridge
(4) and that fastens the lid (12) of the can (1). It can be seen that the inner face
of the outer wall (31) has a surface slit (34) which enables the action of clipping
or removing the device (2) to be more comfortable.
[0024] As seen in Figures 3 and 4, the device (2) can have a straight or curved linear configuration,
with the aim of being able to adapt to any type of circumference configuration of
food cans, just as the device (2) can comprise a notch (6) with the function of freeing
up space for the ring or handle of the food can, usually known as an easy-open element,
said notch (6) being located in the surface of the fastening tab (5) seen from above.
[0025] Having sufficiently described the nature of the invention above, taking into account
that the terminology that has been used in this specification should be taken in a
broad and non-limiting sense, as well as the description of the best mode of carrying
it out in practice, and, it having been proven that it constitutes a positive technical
