Definitions
- the invention relates to a carrier bag according to the preamble of claim 1.
- Such carrier bags are used in particular in trade and are for the
- Such a carrier bag generally consists of a rectangular and elongated strip of material which is folded over approximately half its length and thus forms a bottom surface in the envelope region and two side parts extending on both sides of the bottom surface. Both side parts are welded together at their side edges, so that there is a closed pocket volume with an upper pocket opening.
- each side part has a handle firmly connected to the side part and elements for closing the upper pocket opening.
- the carrier bag is made of a special material in order to isolate the temperature of the food purchased from the outside temperature of the surroundings for as long as possible.
- a foam sheet with a lot of air inclusions.
- this carrier bag has only low insulating properties due to its low material thickness.
- To improve the insulation it is generally known to place a transparent plastic film on the outside of the foam film in order to obtain two-layer side parts.
- the additional air space gained between the Foam film and the transparent outer film significantly increase the insulating ability of the bag.
- this increased insulating force becomes ineffective when the food, with its generally rigid and mostly prismatic body shapes, press against the side parts of the carrier bag from the inside and thus shift the air layer enclosed between the foam film and the outer film. As a result, the insulating force of the additional air layer is lost in the compressed areas and thus especially in the immediate area of the food.
- the carrying bag has specially designed handles to accommodate the relatively high loads of the food purchased.
- handles For example, it is generally known to design both handles from a rigid plastic material and, for better load distribution, to carry out lateral outrigger arms made of the same plastic material as the handles, which extend over the entire width of the side parts.
- Such handle designs are very expensive to manufacture, so that they are forbidden for the majority of applications.
- closure elements are also very expensive. In addition, they are very little resilient. Because of their prismatic design and their high mass, the bulky foods exert a strong internal pressure on the side parts of the carrier bag, which the closure elements generally only have to counteract with their adherence. The carrier bags unlock very quickly under this load and thus expose the food to the conditions of the atmosphere. These closure elements also have a short lifespan.
- EP 0 755 869 A1 now describes a carrier bag with a first handle on the inside of one side part and with a second handle on the inside of the other side part.
- a slot aligned transversely to the filling direction. The length of the slot corresponds approximately to the inner distance between the legs of the handle attached to this side part of the carrier bag.
- the second handle is pulled through the first handle and at the same time through the slot and brought together on the outside of the carrier bag with the first handle struck on the inside.
- This tote bag has major disadvantages.
- the side parts of the carrier bag are only brought together in the area of the handles, while the side parts in the other areas are not held together and are strongly pushed apart by the bulky food. In this open state, the insulating capacity of the carrier bag is practically eliminated.
- Another disadvantage is that one handle has to be guided through a slot in the opposite side part of the carrying bag. Since both handles are on the same mounting level, there are different handle heights in the handle area. This means that the load cannot be evenly distributed over both handles, so that the load is distributed over the solid handle and the slot supported on the solid handle. However, the slot cannot absorb such loads, so that the side part guiding the slot is torn out very quickly.
- the invention is therefore based on the object of improving the load distribution and the insulating ability of a generic carrier bag.
- This object is achieved by the characterizing features of claim 1.
- Expedient designs result from subclaims 2 to 5.
- the particular advantage of the new carrier bag is that the continuous and closable flap enables a hermetic separation of the bag volume from the atmosphere.
- an even distribution of the loads on both handles is achieved, which protects the material of the carrier bag and leads to a long service life of the carrier bag.
- This even distribution of loads is made possible primarily by the fact that the slot is in the envelope flap and not in one of the side parts. This results in new movements for the handles and the slot when closing. In this way, the handles are no longer guided to the stationary and side slot, but the slot is moved into the position above the stationary handles. The handles therefore remain in their vertical position, which is advantageous for uniform load distribution.
- the side parts of the carrier bag are formed in two layers with an air chamber lying between them and if this air chamber is divided into several small air chambers. It is advantageous if these many air chambers are interconnected by damping air exchange openings. With this quilt principle, the air chambers are stabilized against external loads.
- Fig. 1 a carrier bag in a side view in the open state and with a folded-down side part
- Fig. 2 the carrier bag with single-layer side parts in a partial section
- Fig. 3 the carrier bag with two-layer side parts in a partial section
- Fig. 4 the two-layered Carrying bag in a side view.
- the carrier bag consists of a rectangular and elongated film strip, which is folded over by about half its length and thus forms a bottom panel, a first side panel and a second side panel 2 in the cover area.
- Both side doors 1, 2 are welded together at their lateral edges, so that there is a closed joining volume with an upper pocket opening.
- the two side panels 1, 2 are matched to one another such that the second side panel 2 has a greater height than the first side panel 1.
- This envelope flap 3 of the second side panel 2 is dimensioned in accordance with FIG. 2 in such a length that it spans the pocket opening and a height of the side panel 1 sufficient for attachment.
- a slot 4 is incorporated into the flap 3, through which a first handle 5 and a second handle 6 are pulled through when the carrying case is closed.
- the arrangement and the dimensions of the slot 4 are matched to the arrangement and the outer dimensions of the two handles.
- Each handle 5, 6 consists of a foil strip, which is welded at both ends to the inside of the respective side panel 1, 2.
- the first handle 5 is connected to the first side panel 1 via two welds 7 and the second handle 6 is connected to the second side panel 2 via two welds 8.
- the inside of the envelope flap 3 and / or the outside of the first side panel 1 have detachable closure elements 9 which establish a connection to one another.
- These closure elements 9 can be of various shapes.
- the closure element 9 can be an adhesive which is applied as scattering either on the inside of the flap 3 or on the outside of the first side panel 1.
- the closure element 9 can also be a transfer adhesive that changes its fastening location between the flap 3 and the first side panel 1 with each closure.
- the closure element 9 can also be a Velcro fastener with a Velcro strip on the flap 3 and a Velcro strip on the first side panel 1.
- the two side panels 1, 2 with their common base panels consist in a special embodiment according to FIGS. 3 and 4 of a foamed and metallized plastic film which, with its many air inclusions, has good insulating properties and which reflects sun and light rays with its metallic layer.
- IsoHerfoüe 10 made of a colored or transparent plastic is applied to this plastic film, both of which are circumferentially bonded to one another at their edges and on their large side surfaces according to a certain surface pattern in a dot or line shape.
- these air chambers 12 are hermetically sealed from one another or connected to one another via air exchange openings 13. Via these air exchange openings 13, air chambers 12 are connected to one another in such a way that the air quantities outside air chambers 12 can exchange in a damped and thus time-delayed manner.
