The present invention relates to a connecting port for connecting the container and the means for sucking the liquid filled in the container by breaking the thin film installed in the sealed container for enclosing the inlet of the container.

Conventionally, a plastic flexible container conveyed in a cardboard box or the like is filled with a beverage such as coffee or juice, and the bag-in-box method (hereinafter referred to as BIB method) that accommodates the container in a vending machine is used. Vending machines are known.

This BIB vending machine is excellent in that the running cost can be lowered because the empty container after the filling beverage is dropped is not required. Moreover, the liquid in the container can be sucked by the pump without contacting the outside air. Therefore, there is an advantage such as hygienic.

Japanese Patent Application Laid-Open No. 62-258282 discloses a connector for accommodating the container in a vending machine and used to take out liquid from the container.

The connector disclosed in the above publication is composed of a female connector installed in a container and a male connector fitted to the female connector, and when the male connector is inserted into the female connector, the connector is joined to the female connector by a tip formed at the tip of the male connector. The container is opened by breaking the thin film, and in this state, the male body is pushed again to open the valve body formed in the inner cylinder of the male connector, and through the flow path in the vessel and the male connector. The sieve is closed, the inside of the male connector side pipe is shut off from the outside air, and the remaining liquid in the pipe is prevented from flowing out of the male connector.

In addition, Japanese Patent Laid-Open No. 3-69392 discloses that the liquid in the container is always kept from the outside air and the sealant of the container is increased by interlocking the opening / closing operation of the valve incorporated in the connection port with the operation of the suction pump connected to the connection port. .

However, the connection port described in the above publication has a connection resistance when connecting the female connector (plug) and the male connector (socket), or in addition to the sliding resistance of the seal ring. It was not done.

The inventor repeated the experiment of cutting the aluminum foil by pressing the aluminum foil into the conventional socket of the cylinder with the tip of the cutter part installed in the socket, and the body part continuous with the tip. ① The aluminum foil is the place where the cutter tip abuts. Not in the middle, but in three directions. ② The load required when the cylindrical portion of the body portion pushes the aluminum foil bonded to the entire circumferential portion is larger than the load required for the initial opening of the aluminum foil. ③ Since aluminum foil is pushed out from the source to which it is bonded, it was found that aluminum foil could be easily peeled off and peeled pieces could be mixed in the beverage.

In addition, an object of the present invention is to provide a splicing port that is easy to splice without naturally peeling off the sealing thin film.

In order to achieve the above object, the plug-in and plug-out connector according to the present invention comprises a plug provided with a plug provided at an inlet of a sealed container, and a socket having a cutter to break a thin film closing the inlet. The problem is solved by forming the tip portion of the cutter portion in the form of a triangular vertebra, forming a trunk portion continuous with the tip portion in a delta, and forming a flow path through which the fluid in the container flows in the cutter portion.

At the time of connection of the connector, when the socket is inserted into the plug, the tip of the cutter portion of the socket contacts the sealing thin film provided at the inlet of the plug and presses the thin film, so that it starts to divide in two directions near the center of the thin film.

When the socket is kept pressed, the division progresses by the tip portion and at the same time, the division in the center is newly started in one direction. As a result, the thin film is divided almost equally in the radial direction as if the Y-shaped growth is in three directions.

If the socket is kept pressed again, only the thin film portion of the trunk portion of the cutter portion is pushed along the wall (that is, the triangle) of the trunk portion.

In this way, the thin film is divided by the tip portion and the trunk portion, is expanded, and the flow path is opened.

Hereinafter, with reference to the drawings will be described a preferred embodiment of the present invention.

1 is a longitudinal side view showing a connection state between a socket having a valve built therein and a connector formed of a plug.

The plug 10 shown by the dashed-dotted line in the figure consists of a plug outer cylinder 12 and a plug inner cylinder 14 which is fitted through the zero ring 13 inside the outer cylinder 12. A flange 15 is formed at the container side opening end of 12), and the flange 15 is hermetically fixed to the inlet portion of the container 2.

A set of protrusions 16 are formed on the outer circumferential surface of the plug outer cylinder 12 at the connecting portion side, and a flange portion 19 is formed at the opening end of the plug inner cylinder 14 at the connecting portion side, and the outer cylinder 12 is formed. It is regulated not to move.

An opening 17 having a predetermined diameter is drilled and installed in the central portion of the plug inner cylinder 14 in the axial direction, and the opening 17 is closed by a thin film 18 that is relatively easy to be cut by a sharp blade or the like. As the thin film 18, aluminum foil is often used for safety and hygiene requests. The plug 10 having the above-described configuration is provided in close contact with two opening portions of a container filled with a liquid such as a beverage, and the liquid inside the container is properly blocked from the outside air by the aluminum foil.

On the other hand, the connection part side of the socket 20 shown by the solid line has the valve body 30 built-in, and it can freely rotate to the socket inner cylinder 22 which can be fitted to the plug inner cylinder 14, and the outer peripheral part of the inner cylinder 22. And a sleeve 24 fitted to the outer circumference of the plug outer cylinder 12 at the time of connection with the plug 10, and freely inserted into and detached from the sleeve 24 and the front portions of the sleeve 24. It is generally formed by the locking ring 28 which is slidably fitted in the direction orthogonal to the axial direction of the socket inner cylinder 22 in the space | interval part formed between the cover 26 to which it was fitted.

A force is applied to the connecting portion side by the compression coil spring 32, and the valve body 30 is pressed to the connecting portion side in the illustrated standby state to close the fluid passage 23 of the socket inner cylinder 22, and suction not shown. When the pump is started, the valve body 30 retracts against the repulsive force of the compression coil spring 32 by the suction force of the pump, and the fluid flow path 23 is opened to release the liquid filled in the container 2. It can be taken out of the container (2).

The entire outer circumferential surface of the socket inner cylinder 22 is provided with a zero ring 34 for enclosing both inner and outer peripheral surfaces when the inner cylinder is fitted to the plug inner cylinder 14.

The cutter portion 40 is screwed to the connection portion of the socket inner cylinder 22 with a male screw 41 as shown in an enlarged view in FIG. 2B. As shown in FIG. 2A, the cutter portion 40 has a tip portion 42 in the form of a triangular weight, and the continuous body portion 43 is formed in the form of a triangular weight, and has a flow path 44 in the axial direction. .

By the way, as described above, the experiment was carried out by dipping the aluminum foil with a known socket having a cylindrical portion and a continuous cylindrical body formed in the tip portion as follows.

(1) When the aluminum foil was pressed on the tip, the aluminum foil began to divide in two directions in the radial direction near the center, not where the tip of the aluminum foil contacted, and the load at this time was about 0.6 kgf.

(2) When the tip portion continues to be pushed again, the division of the aluminum foil proceeds, and a division of one direction is newly started near the center of the aluminum foil at a load of 1.4 to 1.6 kgf. That is, this aluminum foil is necessarily divided | segmented substantially equally in three directions.

(3) After the aluminum foil was divided in three directions, the tip was kept pressed, and the tip pushed the aluminum foil along the circular shape of the outer periphery of the tip, and the load reached 3.0 to 3.5 kgf. This is thought to be because even if the aluminum foil is divided in the cone part of the tip, a large force is required to push out the entire aluminum foil in the vicinity to which the outer peripheral surface of the body is bonded.

4 is an enlarged front view showing a state in which the aluminum foil 18 is stacked, and in this case, the aluminum foil 18 is pushed in a circular shape. Reference numeral 42a is a cone tip.

(4) When the aluminum foil was pushed in a circular shape, the aluminum foil was pushed out from the source of the adhesive surface of the aluminum foil, which is near the opening 17 of the plug, so that the aluminum foil could be peeled off and mixed in the beverage. .

(5) Thus, in the above experiment, the inventors made the same experiment on the same aluminum foil as a socket having a triangular shape of the tip portion and a continuous trunk portion of the triangular circumference. Same as 1), but the load of aluminum foil was reduced to 0.4 ~ 0.7kgf.

This is because the aluminum foil of only the part of the rupture is pushed outward along the wall of the delta, in which case the wrecked trace of the aluminum foil is pushed out in the shape of a triangle. Therefore, since an adhesion part does not apply pressure, aluminum foil does not peel.

3 is an enlarged front view illustrating a state in which the aluminum foil 18 is cut by the cutter portion 40.

Looking at the above experimental results, the cutter portion 40 of the present invention is the triangular shape of the tip portion 42, the continuous trunk portion 43 is a triangular weight equal to the length of each side of the triangular weight.

On the other hand, the end opposite to the connecting portion of the socket 20 is screwed with the adapter 60 in the orthogonal state to the outer peripheral surface thereof, and the 0 ring 51 is interposed on the outer peripheral surface of the opposite side to the connecting portion of the socket inner cylinder 22. The fitting socket outer cylinder 50 and the longitudinal gap 52 for passing the fluid are in the whole 53, and this whole 53 is screwed into the inner peripheral part of the rear end of the socket inner cylinder 22, and it is a rear part. It is comprised by the cap 56 which fits the said socket outer cylinder 50 to 54 from the back via the 0 ring 55. As shown in FIG.

The tube 61 connected to the adapter 60 communicates with a suction pump (not shown).

Next, the operation of the above embodiment will be described.

In order to connect the socket 20 to the plug 10, the socket inner cylinder 22 is inserted at the distal end with respect to the plug inner cylinder 14, and the plug inner cylinder 14 is opened by the cutter portion 40 of the socket inner cylinder 22. The thin film 18 which seals the sphere 17 is dug up. The thin film 18 is divided in the tip portion 42, expanded in the body portion 43, as described in the experimental results using the cutter portion of the triangular weight, and the flow path 44 of the cutter portion 40 is opened. The fluid passage 23 in the container 2 and the socket 20 communicate with each other.

Parallel to this, the taper part 102 formed in the locking ring 28 of the socket 20 is engaged with the taper part 101 of the plug 10. By pushing the socket 20 to the left in FIG. 1, the locking ring 28 is pushed downward against the force of upward compression of the compression coil spring 24a. When the socket 20 advances again and the taper portion 102 of the locking ring 28 reaches the circumferential groove 103 formed on the outer circumference of the plug outer cylinder 12, the upper portion of the coil spring 24a is shot. The locking ring 28 is pushed upward by the force and caught in the circumferential groove 103 to complete the connection of the plug 10 and the socket 20.

Since the connection port of the present invention has the shape of the tip of the cutter portion as a triangular weight and the shape of the body portion as a delta, it can be naturally broken without peeling off the sealing thin film, and the sealing container and the suction means can be easily connected.

Therefore, the connection by a connection port takes time, and the airtight state in a container does not become bad, and it is extremely effective as a connection port especially used for piping inside a vending machine of a BIB system.
