Reusable, portable beverage container with cooling function

Abstract

Flexible beverage pouch, characterized in that it comprises an inner liquid pouch and a gel chamber surrounding it, wherein the liquid pouch has a funnel-shaped opening with a closable stopper, so that the filled beverage is surrounded by a cooling gel layer and at the same time a safe filling and drinking option is provided.

Description

[0001] The invention relates to a flexible beverage bag with an integrated cooling chamber, particularly for use at events, festivals and in the leisure sector.

[0002] Since both beverage pouches and gel-filled ice packs are known, but no flexible beverage pouch with a permanently integrated cooling chamber is currently available, this product combines both. This ensures that the beverage inside is automatically surrounded by a cooling gel layer.

[0003] The product is designed to provide a flexible beverage pouch that keeps the liquid inside cool for an extended period without the need for external cooling devices. It is also crushable, portable, and features both a small and a large closable opening for drinking, making it suitable for festivals and large events.

[0004] The pouch consists of three layers: an inner liquid pouch 1 with a funnel-shaped opening 6 for filling. The second layer comprises a surrounding gel chamber for cooling 2. An insulating air layer 3 can be provided between the gel chamber and the outer shell. This air layer improves thermal insulation, allowing the cooling gel to maintain its temperature for a longer period and preventing immediate heat loss. The outer pouch is shaped to allow it to stand upright on a flat surface. All three layers of the pouch are joined at the top by a common weld seam 7, which has two openings 5 ​​for a carrying strap. Wide weld seams 4 are also present on the sides for increased stability of the entire container.

[0005] The bags will be made of a thermoplastic, weldable film in various thicknesses. The stopper will be made of a soft, weldable material.

[0006] An embodiment of the invention is described by reference to the Fig. 1 to 4 explained. They show: Fig. 1. The front view of the entire product Fig. 2 the section of the multi-layered bag Fig. 3. Side view of the plug Fig. 4. View of the plug from above in the open state EXAMPLE

[0007] For use at large events, the bag has a fill capacity of 500 milliliters.

[0008] In a preferred embodiment, the inner bag has a cut size of 15 cm × 26 cm with 8 mm side welds and a 2 cm top weld. This provides an effective internal volume of 500 ml. The gel chamber is trapezoidal and surrounds the inner bag by approximately 5 mm. A 0.5 mm thick TPU film is located between the two chambers. The gel chamber is enclosed by a 0.8 mm thick TPU film. This air gap is typically 2–3 mm in my preferred embodiment. This air cushion reduces heat loss from the gel to the outside and improves the bag's handling, as the outer layer cools down less. At the same time, the bag remains flexible and squishy. The base of the outer layer is elliptical and made of 1 mm thick TPU film with axes of 6.5 cm and 3.5 cm, which gives the bag its stability.

[0009] The stopper is made of a weldable and soft material such as TPU, as are the funnel-shaped opening connected to the stopper and the further opening in the larger stopper for a straw. This opening can be closed again with a stopper that is connected to the larger stopper. ADVANTAGE

[0010] The beverage pouch according to the invention has the advantage that it can be used without external cooling and yet keeps the beverage cool for an extended period. The opening offers various options for drinking the beverage as well as for completely sealing the container and protecting it from the unintentional addition of foreign substances. It is crushable, lightweight, and portable thanks to the carrying handle, making it particularly suitable for outdoor activities. Furthermore, the TPU film construction is food-safe and reusable.
