Description

[Detailed description of the invention]

The present invention relates to an apparatus for taking out the contents of a sealed container, and in particular, to take out a fluid substance stored in a flexible sealed container, which is easily deteriorated by contact with the outside air, in a sealed state and with a desired flow as necessary. Furthermore, the present invention relates to an apparatus for removing the contents of a sealed container that can smoothly replace the sealed container without leaking a fluid substance to the outside when replacing a new sealed container upon completion of removal. The present applicant has already proposed a device for taking out the contents of a closed container in Japanese Patent Application No. 192041/1982.
Examples are shown in FIGS. 1(a) and 1(b). FIG. 1(a) shows a take-out device 100 for taking out coffee materials such as liquid, viscous material, powder, etc., which are the contents of a flexible airtight container l such as a standing pouch (self-standing pouch) housed in a protective cover 116. FIG. 1B shows a partially enlarged cross-sectional view of the dispenser @ 100 of the coffee dispenser. As shown in FIG. 1 (b), a device 1 for taking out, for example, concentrated coffee material filled in a flexible airtight container l.
00 is a cap 103 having a predetermined outer diameter, which is bonded to a side wall 4 made of a thin aluminum plate or the like, has a screw 101 on the outer periphery and a thin film seal 102 that seals the opening, and the screw 101 of the cap 103 and the screw. Thin film seal 1 inside engaged
A seal holder 105 has an elastic seal ring 104 that holds down the seal ring 1, and the left end 106 has a seal ring 1
The right end portion 107 sealsly engages with the inner circumferential portion of 04.
The rotation knob) 108 is screwed into the suction tube 2 in the middle.
A main body (or housing) 110 having a connector 109 connected to the pump 25 through the main body 110, and an opening cutter 111 for breaking the thin film seal 102 at one end formed on the inner wall of the main body in the middle part. It is composed of a shaft 114 having an elastic valve body 113 that engages with a valve seat 112 and whose other end is fixed to the handle 108, and an elastic seal cylinder 115 provided between the main body 110 and the shaft 114. . In the above configuration, to explain its operation, the thin film seal 102 of the mouthpiece 103 connected to the flexible airtight container 1 containing concentrated liquid coffee or the like is inserted into the handle 108.
The contents can be taken out by a simple operation of moving the shaft 114 to the left by rotating the cutter 111 from the position shown by the solid line to the position shown by the dotted line. Since the elastic seal ring 104 and the elastic seal cylinder 115 are provided, the contents 2 and the outside air are completely shut off. The contents 2, such as concentrated liquid coffee, are dispensed via the connector 109, for example by pump suction of a dedicated dispenser or by pressurizing the flexible closed container 1 from the outside. This retrieval device 100 moves the shaft 114 by rotating the handle 108, and therefore the elastic valve body 113 moves in the axial direction, so that the contents 2 can be freely adjusted and the contents can be removed from the closed container l. The removal of the object 2 can be stopped and started at any time in a state where it is cut off from the outside air. As mentioned above, this extraction device has some special features.
However, after the thin film seal 102 is broken and opened by the cutter 111, the inside of the main body 110 and the inside of the suction tube 20 remain in communication (connection). When exchanging the suction tube 20, there is a risk that the contents remaining in the suction tube 20 may leak out from the left end opening. The present invention has been made in view of the above, and provides a trap for replacing a flexible sealed container for replenishment when the contents of the flexible sealed container are consumed, and the contents of the suction tube do not leak to the outside, ensuring stable quality at all times. Flowable contents such as liquids, viscous substances, powders, etc. as required.

[In order to ensure smooth supply, when replacing the sealed container, the elastic valve body is moved to a predetermined position in the axial direction of the main body so that the suction tube can be sealed and shut off.
The fluid contents stored in the flexible airtight container are supplied by pump suction or external pressure at a desired flow rate when necessary in a completely sealed state without replacement with outside air,
The present invention also provides a closed container contents removal device in which the elastic valve body can restore the seal. FIGS. 2(a), (b), and (c) show an embodiment of the present invention, and (a) shows a closed container contents removal device Zoo attached to a standing pouch type flexible closed container 1.

The attached sealed container contents removal device 100-M is shown, and 25 is a suction pump and 30 is a tip. FIG. 2(c) is an enlarged sectional view (first
Components that are the same as those of the take-out device 100 shown in the figure are given the same reference numerals), and are adhered to the side wall 4 of the closed container l, have screws 101 on the outer periphery, and seal the opening with a thin film. A seal holder 105 has a built-in elastic seal ring 104 that threadably engages with the screw 101 of the cap 103 and presses the thin film seal 102, and the left end 106 is the inner periphery of the seal ring 104. The right end m107 is threadedly engaged with the nodle (or rotary knob) 10B, and a small Jxso (its function will be described later) extends axially over a predetermined distance on the middle inner wall and a tube in the middle part. The main body (or housing) has a connector 109 that is connected to the pump 30 via a connector 20, and a thin film opening cutter 111 configured to break the thin film seal 102 at the left end, and a sealing seal on the right side.・It has a cylinder 115 and the right end is 7.
The shaft 114 is fixed to the shaft 114 (integrated with the handle 108) and the shaft 114 is fixed to the middle part of the shaft 114, and the left side surface can be engaged with the valve seat 112 formed on the inner wall of the main body in the axial direction. O-rings 151 are provided at both ends to seal and shut off the inside of the connector 109 and the inside of the main body.
The rotary knob 108 is composed of an elastic seal valve body 152 and a lid 117 fitted in the center of the rotary knob 108. In the above configuration, the operation will be described with reference to FIGS. 3 and 4. A standing pump filled with concentrated liquid coffee or concentrated liquid juice, etc., is housed in a pouch or bag-in box 116. The thin film seal 102 of the cap 103 adhered to a flexible airtight container l such as a pouch is rotated by the rotation of the rotation knob 08, that is, the position of the stop lines S, L carved on the surface of the main body 110 shown in FIG. (corresponding to the state shown in Fig. 4 (a)) to cut line 0°L, (7) position (corresponding to the state shown in Fig. 4 (b))! ! Rotate knob 10 with
B is rotated to align the left side 1111 of the rotary knob with the line, and the cutter 111 is then moved to the left in the axial direction to break it. Next, rotate the rotary knob 108 in the opposite direction and return its left side to the open line O0L position (corresponding to the state shown in FIG. 20 and a suction pump 25 are connected, and the contents 2 of the closed container 1 are supplied to the cutter 30 by the operation of the pump or external pressure. When all the contents of the sealed container 1 have been drained and the used sealed container is to be replaced with a new sealed container 1 for replenishment, the screw engagement between the connector 105 and the cap 103 is first released. At this time, the content suction tube 20 and the inside of the main body 110 are in communication (connection) state as shown in FIG. ) is the cap 1133 (t or connector 10

According to the external seal valve body s, 42f, 4th
As shown in Figure (A), move it directly above the connector 109 to cut off the connection between the suction tube 20 and the inside of the main body. Next, the threaded engagement between the C base 103 and the connector 105 is released from this cut-off hearing. By repeating the above operations, the flexible airtight container for replenishment can be smoothly replaced one after another without the contents leaking outside the car. When moving the cutter 111 from the position shown in FIG. 4 (a) to the position shown in FIG. Content chamber 15 formed between
Cutter 1 due to the compression resistance of the contents accumulated in Cutter 3
However, in the present invention, since the small groove 115 is provided in the inner wall of the main body over a predetermined length along the axial direction, the contents of the reservoir chamber 153 are Since the cutter 111 moves to the space between the two O-rings 151 through the cutter 111, there is almost no compression resistance caused by the contents, and the cutter 111 can move smoothly. Although the 7-required airtight container 1 of the present invention described above has been explained as a single unit, a plurality of flexible airtight containers may be used in parallel if necessary, and a plurality of contents removal devices 100M can be used correspondingly. used. For example, Figure 5 shows three yts for 10-fold dilution (unsweetened).
A flexible airtight container lA for condensed rt coffee, one flexible airtight container lB for concentrated liquid coffee for 6-fold dilution (sweetening), a flexible airtight container ilO for milk, and a flexible airtight container for other additives. A plurality of closed containers consisting of container IDs are shown. Each of these containers is equipped with the above-mentioned content foaming device 100M, and one container exclusively for liquid coffee is equipped with a coupler 21.
and via valve 22 to a pump (not shown) and vessel IB, 10. Each ID is connected to a pump via a valve 22. Above, we have mainly explained the extraction device that provides liquid coffee material with consistently stable quality, flavor, and aroma, but the extraction device can also be used for many other purposes, such as food vending machines and fully automatic soft drink dispensing devices. It can be used to hygienically supply food when isolated from the air, to reserve fuel for motor vehicles, to prevent oil oxidation in tanks, and to prevent anhydrous bacteria in drinking water tanks for emergencies. Possible uses include supply. As described above, according to the apparatus for taking out the contents of a closed container according to the trap of the present invention, the elastic valve body is moved to a predetermined position in the axial direction of the main body so that the suction tube can be connected and connected in a sealed manner, and the flexible closed container is The stored fluid contents are supplied by pump suction or external pressure at a desired flow rate when necessary in a completely sealed state with no exchange with outside air, and the seal can be restored by the elastic valve body. Therefore, when replacing the flexible sealed container for refilling as the contents of the flexible sealed container are consumed, the contents of the suction tube do not leak to the outside, and the contents such as liquids, viscous substances, powders, etc. of stable quality are always required. It can be supplied smoothly according to the requirements.
