Description

Beverage ingredient storage container with piston dynamic puncture outlet Technical field

The invention relates to a storage container for filling ingredients, in particular to a beverage ingredient storage container having a dynamic piercing outlet of a piston.

Background technique

Currently in storage systems for preparing beverages, storage containers for dispensing beverages of different temperatures using a dispensing system are well known in the art. The substance for extracting the beverage is contained in a sealed injection container made of a main injection molded or thermoformed plastic material or a metal material such as aluminum, and a dispenser and a storage container usable for the dispenser are common in the market. The beverages produced by machines and storage containers are typically coffee, tea, chocolate or milk. The following are common beverage ingredient storage containers and their problems:

1. The ingredients in commercially available storage containers are usually in powder form, but do not involve liquid ingredients, especially thick gelatinous liquids, which have a limited range of applications.

2. In the preparation of a beverage product, the ingredient powder can usually only be prepared in small cups of high-concentration beverages (such as espresso), or in large-volume low-concentration beverages (such as American espresso); and can only be singly selected. It has a storage container with high viscosity or high concentration (for example: espresso) and instant beverage preparation, and the capacity is only 30-120ml; it has a low-concentration, low-viscosity beverage, usually 140- Between 300ML, and the two production principles and systems can not be combined. When the amount of the beverage to be prepared is large, it is unacceptable to limit the concentration of the beverage to be produced and the taste.

3. When the beverage is extracted, the bottom of the storage container is pierced from the outside by a piercing element disposed on the machine to allow the beverage to flow outward through the piercing member. When a beverage is made using a storage container, the liquid collection and output ports through the storage container are conventionally through the passage of the preparation machine or the piercing element on the machine. There is an inevitable taste impact and cross-contamination risk (eg, after the first cup of coffee, the second cup of herbal tea, the taste of coffee in the tea drink).

4. The existing mechanical holding device of a machine performs the external force of pressing on the storage container to achieve the function of piercing the outlet. It allows the beverage to be delivered directly into the cup, and there is no other contact between the extracted beverage ingredient storage container and the cup. The holding container on the preparation machine for matching the storage container fixes and limits the size of the storage container, thereby affecting the dosage and variety of the beverage to be prepared, and the consumer's diverse needs are limited.

5. A conventional storage container having an opening as a passage for opening the extracted beverage to the outside. Such an open storage container can easily contaminate the open channel section.

6. A conventional cartridge for coffee or soluble matter, when the pressurized water flows through the container, when the liquid flows out, and the water flow path is opened, the resistance of the filter portion or structure of the cartridge to the water flow is generally reduced, that is, The pressure in the cartridge is reduced, resulting in changes in liquid flow rate and ingredient extraction, and unstable intracavity water pressure, causing inconsistent product problems. Inconsistent problems with output fluids are unacceptable for those who must accurately control the preparation of beverages for formulation.
