Abstract

A container (1) comprising a compartment (4) which is defined by flexible walls and whose volume depends on the relative position of the walls, two opposite side walls (2) being joined along a common connecting portion (5). The container is characterized in that a first gas-filled duct means (11) is arranged in the connecting portion (5) along at least a first side (12) of the container (1). The invention also concerns a method of producing such a container by forming at least one gap in said side walls (2) in connection with the forming of the connecting portion (5) and, in connection with the filling of the container (1), filling each gap with gas and sealing it to form a gas-filled duct (11, 16, 18).

Description

contained a means of transfer, in which the second gas-filled channel means is placed.

Thanks to this design of the carrying means, it will be much easier to use the container, since the user will not grab the flexible side walls of the container. In addition, the provision of a second gas-filled channel means in the transfer means will provide an easy-to-grip handle.

In another preferred embodiment of the invention, the first gas-filled channel means is continuous with the second gas-filled channel means and communicates with it. This means that when the transfer means is captured, air is forced from the second channel means into the first channel means, which increases the pressure and thus the stiffness along the side of the container on which the transfer means is located. Therefore, when lifting the container by the handle, its rigidity and stability temporarily increase, which is very useful.

In another preferred embodiment, the gas-filled channel means is filled with air.

In addition, the container is preferably made of a material that contains a mineral filler and a polyolefin binder. Mineral filler can consist of chalk (calcium carbonate). This choice of material is useful because this raw material is inexpensive, and the finished product is environmentally friendly and easily disposed of.

Next, the invention is described in detail by way of example with reference to the accompanying drawings, which illustrate the currently preferred embodiment of the invention.

Fig. 1A and 18 show an embodiment of the container 1 according to the invention, filled with liquid content, in an unopened state. Container 1, in particular, is intended for liquid food products, for example, milk, water, juice or wine.

The container 1 is of the compressible type, that is, the type that is compressed or folded, and contains three flexible walls, two of which are opposite side walls 2, and the third is the bottom wall 3. Walls 2, C are mutually connected to form a compartment 4 , the volume of which depends on the mutual location of the walls 2, 3.

Fig. 2A shows a top view of the container 1 shown in Fig. 1A and 18, with one side wall 2 removed. The walls 2, 3, which form the container 1, are mutually connected along a continuous connecting section 5, which for simplification description can be divided into two parts as described below.

Two side walls 2 are located along the vertical sides of the container 1 and are mutually connected along the side connecting section 6. In the lower part 7 of the container 1, the side walls 2 are also connected to the bottom wall 3, on one side by means of the bottom connecting area 8, along which each side wall 2 is connected to the lower wall 3, and, on the other hand, with the help of the lower connecting area 9, along which all three walls 2 are mutually connected, with (a joint seam). Figure 2A shows a cross-section of the lower part 7 of the container 1, showing how the lower wall C can be located relative to the side walls 2. Thus, the compartment 4 of the container 1 is limited by the side walls 2 and the lower wall 3. The connecting area forms adjacent lines 10, returned to department 4. The seam of the connecting section 5 is preferably performed by welding.

As shown in Fig. 3A, the connecting section 5 along the side sides of the container 1, i.e. the side connecting section b contains the first gas-filled channel means 11. The first gas-filled channel means 11 is located at least on the first side 12 of the container 1, but preferably - also on the second side 13 of the container 1, opposite to the first side 12. The channel means 11 in its simplest form is a channel. This channel is located along the adjacent line 10 between the compartment 4 and the connecting section 5, and must be continuous along the entire side of the container on which it is located.

On the first side 12 of the container 1, the means of transfer 14 is located in the connecting area 5. The means of transfer 14 is preferably located in the upper part of the container 1 and forms part of the connecting area 5.

According to the prior art, the carrying means 14 includes a first substantially circular opening 15 and a second substantially elongated opening 15. As a result, the carrying means 14 forms a handle that allows the user to pick up the container 1 using four fingers, while at the same time a section is formed between the openings 15 , which takes the effort, so that the handle in the other direction does not wrinkle or deform. Two holes 15 are located at an angle of about 25 degrees to a vertical line through the container. As various tests have shown, an angle of 20-30 degrees is most suitable for consumers.

Fig. 38-3C shows other variants of the channel means 11. According to Fig. 3B, in addition to the first gas-filled channel means 11, the second gas-filled channel means 16 can be located in the outer part of the transfer means 14, that is, between the holes 15 of the transfer means 14 and its periphery. The main purpose of the second channel means 16 is to form a three-dimensional, user-friendly handle.

In addition, according to Fig. 3C, the first channel means 11 can be connected to the second channel means 16, forming a common channel means 18. Therefore, the same channel means can provide both the reinforcement of the handle and the reinforcement along the first side 12 of the container 1. The last option is useful due to the fact that the first side of the container 12 is temporarily strengthened when the user grasps the handle and lifts the container 1, since the air present in the second channel means 16 is forced into the first channel means 11. Thus thus, when using container 1, the rigidity of container 1 temporarily increases.

All gas-filled channel means 11, 16, 18 located in container 1 must be filled with air.

It should be noted that, as shown in Fig. 2A, the container 1 according to the invention, like the containers of the prior art, may contain a discharge means 17. The discharge means 17 is located at a distance from the lower part

7 and mostly opposite to it. The outlet 17 can be used to fill the container 1 with the appropriate product, after which it is sealed until opened by the consumer. The outlet means 17 may contain a sealing means, for example, a threaded plug.

In cases where the container 1 has an outlet means 17, at least one (first) channel means 11 must continue upwards along this outlet means.

The outlet part 19, if present, can be located in the connecting area 5 in the upper part of the container 1 against the transfer means 14. The purpose of the outlet part 19 is to form an outlet opening through which the contents of the container 1 can be dispensed in parts. The opening in the outlet part 19 is formed, for example, by separating its outer part.

Channel means 11, 16, 18 are preferably performed by forming, during the formation of the connecting section 5 and means of transfer 14 - gaps 20 in places where channel means are desired. This can be done, for example, by making recesses according to the shape of the gaps 20, using a forming-joining tool (not shown) for the connecting section 5 and the transfer means 14. Thus, the material in this recess will remain intact, and , therefore, gaps 20 will be formed between the parts of the walls 2 included in the connecting section 5 and the transfer means 14. The gaps 20 should be open or open at one end so that they can be filled with gas at a later stage. The gap opening (not shown) is preferably opened together with the discharge opening of the outlet 17. Filling with gas can be carried out when the container 1 is filled with the appropriate product. After filling with gas, the gap 20 is sealed, thereby forming a gas-filled channel.

By positioning the clearance hole together (adjacent) with the discharge outlet 17, the gas filling nozzle can be combined with the product filling nozzle (not shown).

Making channel means 11, 16, 18 in the form of gaps 20 and filling them with gas only in connection with filling the container means that the container 1 is completely flat before filling. Thus, the container 1 according to the invention does not take up any additional space in cases where the container 1 is manufactured centrally and then transported to local manufacturers who carry out its actual filling with the corresponding product.

The formation of gaps 20 by means of notches in the forming tool and the filling of the formed gaps 20 with gas during the pouring operation means that the modification of the existing production equipment is limited only to the modification of the filling nozzle and the forming-joining tool. These two parts of the machine can be easily and quickly replaced, which means that the former production equipment can be used to make both conventional containers and containers according to the invention.

Thus, the present invention offers an improved version of the containers 71 of the prior art, in which the connecting section 5 on at least one side of the container 1 contains a first gas-filled channel means 11 that continues along the side of the container 1. This first gas-filled channel means 11 prevents crumpling and bending of container 1 during careless or long-term use. As a result, the shape and appearance of the container 1 are preserved, while at the same time the risk of leakage associated with abrasion is reduced.

The first gas-filled channel means 11 can be combined with the second gas-filled channel means 16 located in the transfer means 14. The two channel means 11, 16 can be continuous and can communicate with each other.

Strengthening the container with gas-filled channels is useful because it does not require the use of a new type of material or an additional amount of material to produce container 1. This excludes an increase in weight and material costs. The disposal capabilities of container 1 remain unchanged. In addition, the existing production equipment can be used with only minor changes.

It is clear that the present invention is not limited to the shown embodiment of the container. Various modifications and variants of it are possible, which do not go beyond the scope of the invention, which is determined exclusively by the given claims. x Z r Z 14 some sy and s o u m x
