8 Claims.
The invention relates" to a package for loose
particles of food as nut kernels or meats, candies
or small cakes and the like, in and by means of
which the food particles are attractively dis
5 played and at the same time are protected from
deterioration by the action of air, moisture and
other harmful agencies and protected from
crushing and breakage. While the package is
primarily a food package, it may be used for other
small articles.
The package comprises a bag or other sealed
Wrapper preferably a tubular section of trans
parent sheet material which is Water resistant
and may be to a large degree water proof. This
15 material is to the best advantage capable of
sealing by heat though materialsotherwise sealed
may be employed. While moisture resistant ma
terial is preferred, other transparent materials
may be used.
The material which has been used for this pur
pose in- the practice of applicant’s invention is
cellulose hydrate in the form of sheets which are
flexible, transparent, non-absorbent and highly
resistant to the action of water and also self
adhesive under the action of heat so that it is
easily sealed by heating without the use of a
separate adhesive.
The bags may be filled and sealed in accord
ance with the method described in United States
30 Patent #1,986,422 or in any suitable manner, the
bag or inner package being preferably ñat or
capable of flattening. In accordance with the
method of the patent, a strip of Sheet cellulose
derivative of the kind described or any suitable
kind of material is bent laterally into tubular
_form about a feed tube which feeds the food par
ticles into the transparent wrapping tubeas it
is formed. For convenience, this wrapper ma
terial may be referred to as Cellophane, it being
.40 understood however that this word Cellophane is
a trade-mark applied to the product of one man
ufacture and that other sheet materials of this
character may be used for this purpose. The
tube is sealed longitudinally and is also sealed
s. Ui transversely and cut at the center of each trans
verse seal so as to form a series of closed ñlled
--bags, each having flattened portions at its ends
where the front and back of the bags are joined
by sealing.
In accordance with the -present invention these
bags which when unprotected or unsupported are
subject to breakage by bulging >with-the conse
quent spilling of the contents, and are also lack
ing in protection for the food product which is
55 apt to be’crushed and broken> in handling are
(Cl. 20S-46)
well protected. Also these bags in the unsup
ported form are shapeless and not adapted for
quick and easy handling or for packing uni
formly in quantities.A
In accordance with the present invention, these
filled bags or packages are given a uniform shape
and supported and protected from bulging by
means of a paper or other relatively stiff opaque
envelope or backing which is quickly applied and
inexpensive and which exposes the food product 10
in an attractive manner for exhibition an-d ex
This wrapper is easily and cheaply applied _and
of attractive appearance and provides conven
iently for the display of advertising matter in 15
connection with the product, and the package as
completed has the further important advantage
that the food product does not come in contact
With-the paper backing at any point so that there
is no absorption of grease by the paper with the 20
dlspleasing appearance of greasiness and discol
oration and no loss of the food constituents by
the absorbent properties and porosity of the pa
per which are unavoidable incidents to other
paper wrapping or backings. In the accompany 25
ing drawing,'I have illustrated a package em
bodying the features of the invention in the pre
ferred form. In the drawing:
