Description

A POUCH SUITABLE FOR PLACING FILLER MATERIAL THEREIN AND THE PRODUCTION METHOD THEREOF
The present invention relates to a pouch suitable to place filler material therein and the production method thereof.
Vacuum insulation panels are used in various fields since they have better performance with respect to the conventional insulation materials and since they provide better thermal resistance by using the insulating feature of the vacuum. Vacuum insulation panels are produced by putting a porous filler material into a membrane (outer protective envelope) exclusively or together with getter material that retains gas and moisture according to the characteristic of the filler material, vacuuming and closing it by providing leak-proofing.
In the state of the art, the use of two dimensional pouches produced from organic/cellulosic fibers or from various polymeric materials in paper or fabric form enabling the filler material to be filled therein in order to prevent material losses and dust formation of the powder filler material in the pressing and vacuuming steps before being shaped into a plate is known.
The vacuum insulation material not being homogeneously distributed especially to the corners and sides of the two dimensional pouches, adversely affects the thermal insulation performance of the vacuum insulation panel.
In the state of the art German Patent Application No. DE10248854, a two dimensional pouch is disclosed, wherein vacuum insulation material is filled, that is formed of inorganic and organic hybrid polymer layers, the dimensions of which are adjusted according to the size of the vacuum insulation panel and having only a sealing seam left open.
The aim of the present invention is the realization of a pouch that enables the thermal insulation effectiveness of the vacuum insulation panel to be increased.
The pouch realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises a body that is formed by folding on itself a quadrangular first layer produced by knitting polymers like polypropylene, polyethylene, polyamide or organic/cellulosic fibers into cotton or synthetic fabric, preferably a resilient material and joining the abutting pair of sides and one of the two overlapping pair of sides, the body having an upper surface, a lower surface, four corners, and the pouch further comprising an opening enabling to fill the filler material therein and more than one corner stitch (preferably four) disposed at the corners, perpendicular to the lower surface and the upper surface, giving the body a rectangular prism shape such that there is a certain distance (for example between 1 to 3 cm) between the upper surface and the lower surface. The body, the production method of which is facilitated by folding and adhering the first material as a single piece on itself, wraps and protects the filler material filled therein.
A pouch realized in order to attain the aim of the present invention is illustrated in the attached figures, where:
Figure 1 – is the schematic view of the body, the filling orifice, and the support flaps that project out of the body relating to an embodiment of the present invention.
Figure 2 – is the schematic view of the body, the filling orifice, and the support flaps that are folded over the body relating to an embodiment of the present invention.

The pouch (1) of the present invention comprises a body (2) that is formed by folding on itself a quadrangular first layer (L1) produced from a non-rigid material and joining the abutting pair of sides and one of the two overlapping pair of sides, the body (2) having an upper surface (3), a lower surface (4), four corners (5) and an opening (6) enabling to fill the filer material therein, and the pouch (1) further comprising more than one corner stitch (7) perpendicular to the lower surface (4) and the upper surface (3), such that there is a certain distance between the upper surface (3) and the lower surface (4), giving the body (2) a rectangular prism shape. Ease of production is provided by producing the body (2) by folding the first layer (L1) over itself and without requiring to use a separate mould.
In an embodiment of the present invention, the pouch (1) comprises more than one support flap (8) that projects out from the corner stitches (7), the rigidity of which is increased by being subjected to thermal treatment so as to have approximately 45° angle between the sides of the body (2), the support flap (8) extending from the corners (5) inwards when the pouch (1) is turned inside out, enabling the body (2) to keep its rectangular prism shape by bearing against the upper surface (3) and the lower surface (4). By means of the support flaps (8), it is facilitated to give the pouch (1) a three dimensional shape.
In an embodiment of the present invention, the pouch (1) comprises a filling orifice (9) which facilitates the filling of the filler material into the body (2), that is connected with the sides of the body (2) surrounding the opening (6) and that is formed by a quadrangular second layer (L2) produced from non-rigid material, folded over itself and joining the abutting sides thereof. By means of the filling orifice (9), the filler material is filled into the body (2) without being spilled outside.
In an embodiment of the present invention, the pouch (1) comprises a longitudinal stitch (13) extending along the upper surface (3), the lower surface (4) or the side surface of the body (2), enabling the abutting sides when the first layer (L1) is folded to be joined.
In an embodiment of the present invention, the pouch (1) comprises a transversal stitch (10) that is arranged opposite to the opening (6) in the body (2) and that enables the overlapping sides when the first layer (L1) is folded to be joined.
In an embodiment of the present invention, the pouch (1) comprises a filling orifice stitch (11) that extends along the filling orifice (9) and that enables the sides that abut when the second layer (L2) is folded to be joined.
In an embodiment of the present invention, the pouch (1) comprises a joining stitch (12) that enables the filling orifice (9) to be joined with the body (2).
In an embodiment of the present invention, at least one of the corner stitch (7), the longitudinal stitch (13), the transversal stitch (10), the filling orifice stitch (11) or the joining stitch (12) is formed by plastic welding.
In an embodiment of the present invention, at least one of the corner stitch (7), the longitudinal stitch (13), the transversal stitch (10), the filling orifice stitch (11) or the joining stitch (12) is formed by stitching thread.
In an embodiment of the present invention, the production method of the pouch (1) comprises the following steps:
  • Folding the first layer (L1) and joining the same with the longitudinal stitch (13) and the transversal stitch (10) for producing the body (2),
  • Giving the rectangular prism shape to the body (2) by means of the corner stitches (7),
  • Folding the second layer (L2) and joining the same with the filling orifice stitch (11) for producing the filling orifice (9),
  • Joining the filling orifice (9) to the body (2) by means of the joining stitch (12),
  • Turning the pouch (1) inside out and enabling the support flaps (8) to extend inwards from the corners (5) of the body (2).
In this embodiment, during the production of the body (2), after adhering the sides of the folded first layer (L1), only one of the open sides is joined by thermal adhering such that the formerly adhered part remains in the middle or on the side. The side of the body (2) left open is turned inside out such that the inner part of the side faces outside. The produced filling orifice (9) is placed to extend inside the body (2) from the upside turned side and the overlapping filling orifice (9) and the sides of the body (2) are adhered by heat sealing by placing a fireproof – nonstick material at the inner side of the filling orifice (9). The filling orifice (9) must stay open so that the filler material can be filled into the body (2). After the heat sealing process is completed, the fireproof – nonstick material placed at the inner side of the filling orifice (9) is taken out. The pouch (1) that takes the form of a two dimensional bag and subjected to 90° angle heat sealing process from the corners (5) is turned inside out for making the pouch (1) three dimensional. By means of the turning inside out operation, the pouch (1) gains depth before filling the filler material into the pouch (1). By means of the pouch (1) having gained depth, the filler material is easily filled into the pouch (1) and the material density difference especially between the corners (5) and the middle parts is decreased.
By means of the present invention, in particular by means of the pouch (1) having three dimensional shape, the filler material is filled into the pouch (1) homogeneously. The thermal insulation performance of the vacuum insulation panel is improved by filling the filler material of the same density to the sides, the corners (5) and the middle parts of the pouch (1). Furthermore, by means of the filling orifice (9), the filler material is filled into the body (2) more easily. Ease of production is provided by means of producing the pouch (1) by folding a single material without requiring to use a separate mould.
