PACKAGE FOR PASTE-LIKE PRODUCTS
Abstract
A package for paste-like products is designed as a packet of a
flexible material whose body is defined by walls, a bottom, and a
top. The top comprises a covering element, and an opening line is
provided between the covering element and the rest of the body. The
opening line can include incisions or perforations and a notch at
the edge to ease opening the packet. Provided in the area adjacent
to the opening line are strip-like forming elements made of
inflexible material. The strips are nearly as long as the opening
line, and thanks to their inflexibility, the mouth of the opened
packet is defined by the strips and looks like a slot with at least
two opposite sides parallel to each other. This structure results
in obtaining a band of the paste-like product having a
substantially uniform thickness when it comes out of the
packet.

[0001] This application is a Continuation in Part application of
U.S. patent application Ser. No. 12/737,654, filed Feb. 3, 2011,
which is a US National Phase Application of PCT/RU2009/000353,
filed on Jul. 14, 2009. PCT/RU2009/000353 claims priority to
RU2008133410 filed on Aug. 14, 2008, all of which are hereby

TECHNICAL FIELD
[0002] The following description generally relates to the field of
product packaging, in particular for packaging paste-like products,
and it can be used preferably, but not exclusively, for food
packaging, especially for those traveling, for example, by train or
airplane, and also in packaging medicinal products.
BACKGROUND OF THE INVENTION
[0003] Known in the art is a package for liquid medicines,
specifically, a child resistant sachet (U.S. Patent Application No.
2003/0168375A1, published Sep. 11, 2003), suitable for holding a
medicinal product. The sachet is a three seal sachet, or stick
pack, made from a laminate sheet, the sachet having a fin seal
along a longitudinal axis and transverse fin seals at each end. The
laminate sheet is tough enough to resist tearing unless a notch is
provided with which to initiate a tear. A fold line extends across
a corner of the sachet and through the fin seal, a notch extending
through the sachet in a transverse seal area and perpendicular to
the fold line such that when the sachet is folded a cut is revealed
that allows the user to initiate a tear across the pack opening up
a pouring spout for dispensing the medicinal product.
[0004] Also known in the art is a flexible pouch (U.S. Pat. No.
5,005,734 issued on Apr. 9, 1991) made from at least one layer of
plastic material bonded to form a closed inner chamber for storing
liquid. Peripheral portions of the wall material are contoured and
then bonded to form a closed pouring spout at a corner of the
pouch. The configuration of the spout is defined by the contour of
the bonding in the vicinity of that pouch corner. The pouring spout
is opened by cutting the pouch corner at an angle. The flexible
walls of the pouch are reinforced in the vicinity of the pouring
spout to prevent folding in the vicinity of the pouring spout or to
prevent foaming.
[0005] U.S. Patent Application No. 2005/0031232A1 published on Feb.
10, 2005 provides yet another example of a package forming a
container with two side walls, a base and a top opening. The
container is made from a hand tearable material and has an
incipient tear tab for first opening of the package once it is
filled and sealed. Each side wall has at least a first stiffening
element locally reinforcing the material, the stiffening element
being selected such that the propagation energy of the incipient
tear tab is lower than the rupture energy of the stiffening
element. Each side wall includes means for guiding the incipient
tear tab on first opening, with the incipient tear tab located
between the first stiffening element and the guide means, so that
the tear tab is guided.
[0006] Also known in the art is a sachet for liquid drugs (WO
95/01921 published on Jan. 19, 1995) The sachet is characterized in
that the drug is contained in so-called stick packs. It has one
longitudinal and two transverse seams and an opening groove made at
the edge of the package.
[0007] The packages disclosed in the above publications have
insufficiently satisfactory consumer properties resulting from the
fact that the release of products contained in the packages is
uneven. This is first because, when extracted from the mouth of a
package made of a flexible material, the content of the package has
a random shape. Also, the opening groove made on the flexible
material of the package, if used sharply and carelessly, may result
in the rupture of the package in an unwanted place. In addition,
when opening such a package, a contact between consumer's hands and
the contents of the package is possible.
SUMMARY
[0008] Thus, the problem sought to be solved by the proposed
solution is to improve consumer properties of the package making it
more convenient in the use. In a package for paste-like products
including a packet made of a flexible material and defined by
walls, a bottom and a top openable along an opening line, this is
achieved by providing the packet with inflexible strip-like forming
elements placed adjacent to the opening line and along thereof.
Their length is essentially equal to the length of the mouth formed
when the package is being opened. Thus the shape of a slot formed
when the packet is open is substantially non-deformable, and the
slot is defined by at least two non-deformable and generally
parallel sides. The latter, in turn, allows forming a band of
essentially equal thickness out of the product when it comes out of
the packet.
[0009] Further, the length of the forming elements can be made
equal to the length of the opening line.
[0010] Yet further, to cover the top of the packet, a sealing
element removable along the opening line can be provided.
[0011] Additionally, there can be provided elements defining the
opening line. Preferably, the defining elements include perforation
made on the packet along the opening line.
[0012] Still further, the forming elements can be preferably placed
on an inner surface of the opposite walls of the packet.
[0013] Yet still further, transversal edges of the forming elements
can be bridged to form quadrangle.
[0014] Even further, lateral edges of the forming elements facing
the slot can be made relieved, preferably serrated.
[0015] Other features and aspects will be apparent from the
following description, drawings and claims.

DETAILED DESCRIPTION
[0020] A package 10 for paste-like products according to the
present disclosure is designed as a packet 12 made of a flexible,
for example a plastic material. The packet 12 comprises walls 14, a
bottom 16, and an openable top 18. The top 18 comprises a closing
element 20 that can be detached from the packet 12 along an opening
line 22. The opening line 22 is preferably made in the form of
incisions and/or perforation.
[0021] The packet 12 is equipped with forming elements 24 and 26.
They include strips made of a rigid, inflexible material such as
hard polyethylene. The forming strips 24 and 26 are generally
attached to opposite walls, such as 14a and 14b, of the packet 12.
Though the forming strips 24, 26 can be located on either side of
the walls, it is preferable to place them on the inner side
thereof. The forming strips 24, 26, which by their length
correspond to that of the opening line 22 (they are nearly as long
as the opening line 22), are placed adjacent the opening line 22 to
thus help forming a narrow longitudinal mouth 28 of a slot-like
shape, with at least two sides of the mouth 28 being parallel to
each other. The forming elements 24, 26 may be shaped as strips of
various shape. As shown in FIGS. 4A-4B, lateral edges of strips 30,
32 can be relieved (FIG. 4A), lateral edges of strips 34, 36 (FIG.
4B) can be serrated. Also, strips 38, 40 (FIG. 4C) are shown
bridged by connecting strips 42, 44 to form a quadrangle 46, which
can be technologically convenient.
[0022] Also technologically, packages 10, as illustrated by FIGS.
3A-3H and 3J, can be made in various ways. FIGS. 3A-3E show
packages in a closed state, FIGS. 3B, 3D being top views of FIGS.
3A and 3C, respectively. FIGS. 3F and 3H illustrate opened packages
shown in FIGS. 3A and 3C, respectively. FIGS. 3G and 3J are top
views of packages shown in FIGS. 3F and 3H, respectively. The
packages of FIGS. 3A-3H and 3J differ in the quantity of seams used
in the production of the packages. FIGS. 3A and 3E show a
three-seam structure, FIG. 3C shows a four-seam structure, the
seams in FIGS. 3A, 3C, 3E, 3F, 3H being shown crosshatched with
reference 48. In FIG. 3E, a bottom edge 50 is formed by folding the
package material.
[0023] The contents of the package are accessed by opening the
packet 12 along the opening line 22. By pressing the packet 12, the
consumer releases the content through the narrow longitudinal mouth
28, which is formed between the forming strips 24, 26. The contents
are released in the form of a strip (not shown) and can be
uniformly spread on the surface. This property is convenient when
using so packaged paste-like products such as butter, cheese, a
variety of pastas and sauces, as it helps to avoid using a knife
for buttering, which is especially helpful when it is used in
vehicles, planes, or by handicapped people.
[0024] Opening the packet and extracting the content from the
packet is exercised without contact with the product, as when
opening the package along the provided perforations, the customer
holds the pack by the edge near the line of detachment; this is
convenient, if the contents are fatted or dyeing.
[0025] The size and width of the mouth of the package may vary and
can be predetermined depending on the product being packaged.
[0026] The package is so designed that opening thereof is exercised
along the opening line by the notches and/or perforation. The
closing element is a part of the package and is detachable when the
package is opened Implementation of the inflexible forming elements
and positioning the same adjacent to the edges of the opened
package forms a slot-like shape of the mouth, which imparts the
form of a strip of a required thickness to the product being
released from the package. In addition, such a design of the
package protects the product contained in the package from being
contacted by the consumer's hands, because the rigidity of edges of
the package should be sufficient to prevent an occasional discharge
of the product. The mouth has a shape of a narrow elongated slot
that ensures the release of the contents as a uniform strip. The
forming elements shaped as strips allow for easy releasing the
product contained in the package by pressing the package in a place
free of the forming strips; this ensures a uniform release and
application of the contents to the surface. The opening line made
in the form of perforations allows for the easy opening of the
package by a user along the area of the package compacted by the
elements, and prevents the package from being ruptured in an
unintended place and helps avoid unwanted contact of the packaged
product with the consumer's hands. Thus, as a result provided by
the present disclosure, the aforementioned problem is solved,
namely, the consumer properties of paste-like products' packaging
are enhanced.
[0027] Although references have been made in the foregoing
description to various embodiments, persons of ordinary skill in
the art of food preparation methods and systems will recognize that
insubstantial modifications, alterations, and substitutions can be
made to the described embodiments without departing from the
disclosure as claimed in the accompanying claims.
