Description

[Detailed description of the invention] <Industrial field of application> The present invention relates to a container consisting of a combination of an inner bag, an outer case, and a lid, and is suitable for use as an alternative to beverage containers such as metal cans or pins, especially for fruit juice, etc. It can be used for neutral drinks such as low acid drinks and coffee drinks.

<Prior Art> Conventionally, when storing liquid in a paper tube, paper cup, thin-walled plastic container, etc., the liquid was directly filled into the container. Additionally, paper containers have been developed and marketed as alternative containers to metal cans and bottles.

<Problems to be solved by the invention> However, when filling liquid directly into a container, the letters, pictures, etc. printed on the outside of the container may fade due to heat, so it is difficult to retort, boil, etc. after filling. In addition to being difficult to process, when filled with high-temperature liquid, a depressurization phenomenon occurs as the liquid cools, deforming the container, etc., so it is difficult to sell in stores and in vending machines. There were problems such as unsuitability for use.

Furthermore, when a paper container is used, retort filling and packaging is not possible, so aseptic filling and packaging is required, leading to problems such as an increase in the size of the apparatus.

The present invention was developed to eliminate the above-mentioned conventional drawbacks, and provides a composite liquid container that can be sterilized by retort and does not change the external shape of the container as an alternative to metal cans and bottles. It is something to do.

<Means for solving the problem> The container according to the present invention includes a plastic inner bag A with an open top and bottom, an exterior body B that can house the inner bag A, and a sealed opening of the inner bag A. The lid C has a diameter larger than the outer diameter of the outer bag B, has a convex portion 3 on the bottom, and has a flange 2 projecting around the circumference. The protrusion 3 is inserted and the outer periphery of the protrusion 3 and the inner peripheral end of the inner bag A are glued together to seal one opening of the inner bag A, and the other opening is filled with the product and then glued. Then, insert the inner bag A with the lid C attached to the outer bag B.
The above-mentioned problem is solved by assembling the whole by inserting the lid C into the housing, fitting the convex part 3 of the lid C into the exterior body B, and caulking the flange 2 of the lid C to the outer peripheral end. It is something.

<Function> According to the above means, since the inner bag A is stored in the exterior body after the opening 1 of the inner bag A containing the product is adhered to the convex portion 3 of the lid C, the inner bag A is not attached to the exterior body. It can be retorted, boiled, etc. before being stored, and even when filled with high-temperature liquid, the outer shape of the container will not be deformed by the depressurization phenomenon that occurs as the liquid cools.

<Example> To specifically explain an example of the container according to the present invention with reference to the drawings, in FIG. The opening 1 is bonded to the convex portion 3 of C. B is an exterior body made of a bottomless paper tube that can house this inner bag A. Reference numeral C is a lid capable of sealing the opening 1 of the inner bag A, and a flange 2 having a diameter larger than the outer periphery of the outer case B is provided on the outer periphery of the upper edge thereof, and a convex portion 3 is provided on the bottom. It is formed.

Next, when assembling and using the container according to the present invention, as shown in FIGS. 2 to 6, the protrusion 3 on the bottom of the lid C is inserted into the opening 1 of the inner bag A whose bottom is not sealed. Insert it and glue the convex part 3 of the lid C and the inner peripheral end of the inner bag A to seal the opening 1, then turn it upside down and fill the product G such as liquid from the bottom of the inner bag A. death,
Next, seal the bottom of inner bag A and place product G into inner bag A.
Then, by inserting the inner bag A into the outer package B and caulking the flange 2 to the end of the outer package B, the outer package B can be attached and fixed to complete the present container. .

The inner bag A in the above embodiment can be made of various materials depending on the stored product. Further, the exterior body B may have a bottom, and in place of the paper tube, a paper cup, a plastic container, etc. can be used for the exterior body B. Further, as the lid C, a plastic molded product, a metal molded product such as aluminum, etc. can be used.

Furthermore, when sealing the container, the lid C may be provided with an easy-open mechanism such as a conventionally known pull tab, or the bottom portion of the lid C may be cut off using a knife, can cutter, etc. Stored product G can be taken out.

<Effects of the invention> Since the sealed container according to the invention has the above-mentioned structure, the product stored in the inner bag can be processed as it is by retorting, bolting, etc. before storing the inner bag in the exterior body, and Since the inner bag is attached to the outer case through the lid, the decompression phenomenon of the inner bag will not change the shape of the outer case at all, making it suitable for use in over-the-counter sales or vending machines. Furthermore, since it can be printed separately from the inner bag of the outer package, it has the advantage of increasing the effectiveness of the product in stores.
