Patent Descriptive Report of "IMPROVEMENTS
INTRODUCED IN SANDWICH PACKING".
The present patent concerns to packing industry,
specifically to improvements related to sandwich packing, to
reduce the sale costs and to turn more practical and hygienic fihe
consumption of this food.
In the previous state of art, the sandwich always has
been offered in a cardboard box to allow its transport from the
counter to the consumer's table, together with a traditional
napkin to facilitate its consumption in a hygienic way. However,
although the cardboard box was good for transportation and
offered an improvement in the visual end of the product, it has a
restricted usefulness to this task, because, starting from the
moment in that the sandwich was removed of its interior, it lost
all its purpose and it still turned an obstacle in the tray or the
consumer's table.
When removing the box's sandwich, an uncomfortable
task and sometimes a disaster, in what tells respect the original
form of the sandwich, the consumer didn't get to involve the
sandwich completely with the napkin and he made the retreat of
it in stages, i.e., some part of the sandwich was in the box due to
its size and constitution (done by parts). Due to that situation,
inevitable and constraining, the consumer only had an
alternative, to use the hands to complete the arrangement of the
sandwich.
In most of the cases, knowing about this problem, the
consumer simply removes the sandwich with his hands and after
involves it with the napkin. This practice, totally unsanitary, once
the consumer rarely washes his hands to eat something in snack
bars or " fast-food ", he still has another problem: the final
consumption of the sandwich generated many uncomfortable
situations, such as: to avoid that the dismount of the sandwich in
his hands and to avoid the contact with sauces and fat absorbed
by the napkin.
Considering these problems, the present patent was
idealized. A packing that not only executes the transport
function, but also offers a good conditioning for the sandwich,
allowing its transport from the counter to the consumer's table,
giving it an improvement in the visual end of the .product, as
dismissal the use of the final napkin to hold the sandwich as he
eats it.
The present patent disclosures a special packing
made in low density polypropylene, an inert material and
recyclable used in food packing, that has the similar external
form of a sandwich (in the example, a hamburger), made of two
half joined by one of it's sides with a flexible fold and by a

suitable simple fitting in the other ones. Its inferior part still
contains a cut line to allow its division in two parts.
In this way the consumer can eat half of the sandwich
removing the superior part and holding the same with the inferior
part, without need of removing the sandwich of the packing, and
later to eat more a quarter of the same detaching one of the half
of the inferior part, that can be separated in the cut line, holding
the same in the remaining part, to eat the last quarter.
With that the use of the traditional napkin is released
not being necessary the use of the hands in any moment, once
the packing serves as support for consumption, and it makes it
impossible to touch the sauces and fat with hands, because the
packing material impermeability.
The present sandwich packing can be better
understood with the enclosed illustrations, below related, besides
the numeric references with detailed description that, without
however the resfiriction of it's configuration, as its dimensions,
proportions and the reach of its application.
The figure 1 is a perspective view of the packing.
The figure 2 is an open side view.
The figures 3, 4 and 5 are: frontal, superior and side
of the packing.
The figure 6 is a detail of the fitting of its basic parts.
In accordance with these illustrations and its numeric
references, the present patent refers to a sandwich packing (1 )
with two basic parts: a superior part (9) and an inferior (3), joined
by fittings of the male type (4) female (5) in its borders, which is
interrupted by a flexible fold (6) in one of its sides. The packing
still has in the inferior part (3) a cut line (7) to allow its division
in two parts (3A and 3B) with little effort.
Said parts, when joined form a similar contour of a
sandwich (here, for example, a hamburger) with base and
superior extremity (8) straights and an outline arched (9) in the
fittings level.
