Description

[Detailed description of the invention] [Industrial application field] This invention relates to an airtight sealing device for an extraction container containing raw materials, and more specifically, an airtight sealing device for an extraction container containing raw materials used in a beverage vending machine. It is related to.

[Prior art] As a beverage vending machine, for example,
As described in Publication No. 37798, the concentrated stock solution selected by the customer is heated or cooled and the diluted solution is mixed with sugar and cream in a pot for selling beverages or in advance in a mixing bowl. The majority of products are mixed and sold in pots because of their low operating costs, but they require storage of several cups of undiluted solution and the need to add preservatives to preserve food hygiene. There is a slight off-flavor due to the ingredients, and especially in the case of coffee as a savory beverage, instant coffee made from granulated or powdered ingredients still has a slightly different taste (flavor and richness) than coffee brewed using the traditional method. On the other hand, beverage vending machines that sell regular coffee are now in practical use.

[Problems that the invention aims to solve] However, in the case of conventional beverage vending machines that handle regular coffee, it is troublesome to automatically supply a fixed amount of raw materials and to dispose of the brewed dregs after brewing (extraction) is completed. Since it is difficult to prevent finely ground coffee beans from becoming damp, the raw material must be fed little by little frequently, which increases operational costs and increases the cost per cup.

In order to solve these drawbacks, we created a cup-shaped brewing container with an overfill material attached to cover the opening in the bottom plate, and a raw material containing roasted and medium-finely ground coffee beans for one person. There have been proposals to prevent moisture from entering the raw material and to facilitate the processing of extraction residue after extraction by stacking extraction containers. By stacking empty containers, you can prevent moisture from entering from the opening side of the extraction container, but
One of the lower grades had the disadvantage that, for example, the moisture quality of the raw material would be impaired after passing through the overfill between the previous day's sale and the start of today's sale.

The purpose of this invention is to eliminate the above-mentioned drawbacks, prevent moisture from forming in the raw material in the lower extraction container, and make it possible to always sell regular coffee with good aroma and flavor.

[Means for Solving the Problems] In order to achieve the above-mentioned purpose, this invention is based on a cup-shaped extraction container containing raw materials, which has an overfill attached to an opening in the bottom plate and a certain amount of raw materials inside. This can be achieved by providing a magazine in which a plurality of containers are stacked and stored, and a sealing lid that is removably attached to the bottom of the lowest extraction container held by this magazine via a packing material.

[Function] Attach overfill material to the opening in the bottom plate. Packing material is attached to the bottom of the lowest extraction container held by the magazine that stores the cup-shaped extraction containers containing raw materials in a stacked manner. By placing the sealing lid in contact with the lid through the lid, the inside of the extraction container at the lowest end can be kept airtight.

[Example] As shown in FIG. 1, the hermetic sealing device for an extraction container containing raw materials of this invention has an outlet 22 of a magazine 2 which is made up of a cylindrical body 21 vertically attached to an opening 11 of a base material 1. Two or more sleeves 31 are attached to the lower end of the base material 1 on the side toward the center line of the magazine.
A reciprocating member 33, such as a plunger, is inserted into this and controls the extraction from the magazine 2 by moving its tip end into and out of the magazine outlet 22 from the sleeve end and locking it in the curl of the extraction container. A take-out mechanism 3 consisting of a locking rod 32 is provided, and a sealing lid 44 having a U-shaped cross section is pivotally connected to the end of a support member 41 attached to the lower surface of the base material 1 by a shaft 42 via a support arm 43. A flexible packing material 45 such as silicone rubber is attached to the base material 1, and a reciprocating member 4 such as a plunger is attached between the lower surface of the base material 1 and the support arm 43.
6 is provided with a bottom sealing mechanism 4 attached via joint members 47 and 48.

The discharge mechanism of the raw material-containing extraction container of this invention is constructed as described above, and its operation will be explained below.

First, from the state shown in FIG. 1, after inserting the purchase fee into a beverage vending machine (not shown) and pressing the menu selection button of the vending machine, the reciprocating member 46 that constitutes the bottom sealing mechanism 4 starts vending. The machine operates in response to a signal from the control section of the machine, and as shown in FIG. Rotate it 90 degrees so it won't get in the way.

Next, the reciprocating member 33 that constitutes the take-out mechanism 3
is operated by a signal from the control section, and the locking rod 3
2 and remove the cup body 5 inside the magazine 2.
A curl 52 is provided at the opening of the container 1, an opening 54 in the bottom 53 is closed with an overfill material 55, and raw material extraction containers 5 containing medium-finely ground coffee beans as the raw material 56 are stacked one on top of the other. The lowermost extraction container 5a is disengaged from the curl 52 as shown in FIG.

When the locking state is released in this way, a scraping member (not shown) operates to remove the overlapping state of the raw material-containing extraction containers 5a and 5b and cause the extraction container 5a to fall from the opening 22 under its own weight. During this time, the curl 52 of the one above the extraction container 5b is
Since it is in contact with the inner wall surface of the extraction container 5a, it does not fall quickly, so when the extraction container 5a falls by a dimension slightly longer than the curl diameter, the reciprocating member 33 operates again to advance the locking rod 32 and move it to the next position. extraction container 5b
protrudes into the outlet 22 in the magazine 2 in preparation for engagement with the curl 52 of the magazine 2.

Thereafter, as shown in FIG. 2, the locking rod 32 locks onto the curl 52 of the next extraction container 5b, preventing it from falling.

After the extraction container 5 is taken out from the magazine 2 to the extraction section of the vending machine, the raw material, regular coffee, is extracted using boiling water as is well known, and even after a certain period of time required for this extraction has passed, the next operation by the customer is not possible. If the extraction container 5 is not removed from the magazine 2 or the extraction container 5 is removed from the magazine 2, the reciprocating member 46 operates to rotate the sealing lid 44 by 90 degrees clockwise and close it again through the packing material 45 as shown in FIG. The bottom of the extraction container 5b is sealed to prevent moisture from entering the raw material.

[Effects of the invention] As mentioned above, this invention adopts a means to solve the above problems, so it is possible to completely prevent the moisture of the raw material in the extraction container containing the raw material at the bottom, so that freshly ground It has the effect of enabling the use of a raw material-containing extraction container with low operating costs without impairing the aroma and flavor of regular coffee.
