Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a device for simultaneously opening multiple containers.

[Prior art] A spacer is formed by raising a part of the lever near the output end, and this spacer is inserted into the main body from the outside at the center of the main body and engaged with the needle. The spacer and the main body receive the reaction force of the compressive force of the spring that is attached, and the operating end of each lever of the pair of cap opening devices configured as described above is connected to the cylinder neck of the other cap opening device with a connecting member, When the valve opening devices are separated and this lever is swung, the output end that touches the outer surface of the main body becomes a virtual fulcrum and this spacer rotates, detaching from the needle and being used by the needle by the force of the spring. Devices for simultaneously opening multiple containers are already known.

[Problems to be solved by the invention] In order to accommodate a spring in a limited space and utilize the strain energy of this spring, it is necessary to use a spring with a large spring constant. In addition, in order to open the sealing plate with a needle, it is necessary to apply large strain energy of the spring to the needle, which increases the reaction force that the spacer and main body receive.

In conventional devices, the length from the fulcrum position of the lever to the working end is short, so the force required to remove the spacer is large, and in order to remove the spacer, it is necessary to move in a very limited direction ( for example,
This method has the disadvantage that the two devices must be separated in the horizontal direction, which means that there is little freedom of operation.Also, because the spacer rotates around the fulcrum to release the needle, it stores a large amount of strain energy. This results in further distortion of the spring, which also requires a large amount of force.

[Means for Solving the Problems] In the device for simultaneously opening multiple containers according to the present invention, each of the two opening devices has a main body, a needle, a spacer, and a lever, and the main body has a container socket at one end. The needle is movable in the direction of its own axis within the main body and is given a tendency by a spring to advance toward the socket, and the spacer includes an engaging portion and a pin receiver and is attached to the main body near the other end of the main body. It is removably interposed in the direction perpendicular to the axis and prevents the needle from advancing at the engaging part, and the lever has one end that contacts the outer surface of the main body as the point of force, and a fulcrum near that end that swings freely on the pin receiver of the spacer. The levers are pivotally supported and the points of action are located near the socket, and the points of action of the levers of both plug opening devices are connected to predetermined positions on the other side of the plug opening device by connecting members having approximately the same length, By pulling the cap opening devices apart, the points of action of each lever are pulled and oscillated by the connecting member, and at this time, the linear movement of the points of force on the outer surface of the main body causes the spacer to move on the intervening surface via the fulcrum. It is characterized by being pulled outward to release the needle.

The engaging portion is a bifurcated piece that can freely engage with the neck of the needle, and the pin receiver stands up from both side edges of the base of these bifurcated pieces at right angles thereto and extends on an extension line of the base.

The one end of the lever is formed by being bent at a right angle, and a pin receiver that cooperates with the pin receiver of the spacer is formed by bending a side edge at a right angle in a direction opposite to the one end.

[Operation] When the two cap opening devices are separated, the connecting member causes the point of action of each lever to swing around the fulcrum. The lever's force point touches the outer surface of the main body and cannot swing. On the other hand, the fulcrum is supported by a spacer, which can move in a direction perpendicular to the axis of the needle.
As the lever swings, the point of force moves on the main body, and the fulcrum moves outward at right angles to the axis. As a result, the spacer moves out of the restraining position, and the needle advances due to the elastic force of the spring to open the container attached to each socket.

If the engaging part is a bifurcated piece that can freely engage with the neck of the needle, and the pin receiver stands up from the base of the bifurcated piece at right angles to it and extends on the extension line of this base, the spring will be distorted and the spacer The reaction force of the spring is supported by the main body through the forked pieces by inserting the needle from the outside into the inside of the main body and engaging the bifurcated pieces in the head groove of the needle.

The one end of the lever is bent at a right angle,
If the pin receiver that cooperates with the pin receiver is formed by bending the side edge at right angles in the direction opposite to the one end, align the pin receiver of the lever with the pin receiver of the spacer and insert the pin. When the spacer is inserted into the main body, the bent end of the lever comes into contact with the outer surface of the main body, forming a point of force.

[Example] In the drawings, the same reference numerals indicate the same or corresponding parts.

This multiple-container simultaneous opening device includes two container opening devices 51 and 52, and two containers of approximately the same length that connect them.
It shall consist of connecting members 53 and 54 of books.

The cap opening device 51 includes a main body 1, a needle 2, a spacer 3, and a lever 4.

The main body 1 consists of a cap 12 fixed to a body part 13 by a set screw 11, has a socket 15 at one end 14 into which a container 40 is to be attached, and has a gas outlet 16 opening on the side. The needle 2 is movable in the direction of its axis within the body 1, and is given a tendency by a spring 8 to advance to a position where the container 60 is opened (downward in FIG. 1).

The spacer 3 has engaging portions 31a and 31b that are bifurcated pieces, and insertion holes 32a and 32b for the pin 29.
The pin receivers 33a and 33b are provided.
These pin receivers 33a and 33b stand up from both side edges of the base 34 of these bifurcated pieces 31a and 31b at right angles thereto and extend on an extension line of this base 34. This spacer 3 is attached to the neck groove 17 formed near the upper end of the main body 1, and its bifurcated pieces 31a and 3
It is inserted from a direction perpendicular to the axis so that the neck 18 is sandwiched between the two portions 1b. At this time, the spring 8 is compressed from the front so that the neck 21 formed near the upper end of the needle 2 and the neck 18 of the main body 1 are aligned. As a result, the bifurcated pieces 31a and 31b also pinch the neck 21 of the needle 2 at the same time. If the spring 8 is released here, the reaction force of the strain energy is transmitted to one side of the bifurcated pieces 31a and 31b, and is further transmitted from the other side of these bifurcated pieces to one side of the neck groove 17 of the main body 1 that is in contact with these surfaces. Therefore, it is supported.

The upper end of the lever 4 is bent at a right angle, and the bent piece 4
1, and the edge of this bent piece forms a point of force 42 in contact with the outer surface of the main body 1. Further, both side edges slightly below are bent at right angles in the direction opposite to the bending piece 41 to form pin receivers 43a and 43b. These pin receivers are matched with the pin receivers 33a and 33b of the spacer 3, and the pin 29 is inserted into the insertion hole 3 of both.
By passing through 2b, 44b, 44a and 32a, a fulcrum 45 of the lever 4 is formed. The lever 4 has a point of action 46 at its lower end, and this point of action reaches near the socket 15 of the main body 1.

One end of the connecting member 53 is fixed to the cap 12 in the drawing, and the other end is attached to the point of action 4 of the lever 4 of the device 52.
6. Similarly, one end of the connecting member 54 is fixed to the cap 12 of the cap opening device 52 in the drawing, and the other end is fixed to the point of action 46 of the lever 4 of the cap opening device 51.

In these cases, the connecting members 53 and 54 for the respective cap opening devices 51 and 52 may be fixed to the neck portion 61 of the container 60 attached thereto.

The cap opening device 52 has the same configuration as the cap opening device 51. However, when it is desired that the gas outlet ports 16 of both devices are opened in the same direction, it is preferable to use a planarly symmetrical device.

In addition, in the drawing, 70 is an O-ring.

A container 60 containing gas for replenishment is attached to the socket 15 of each cap opening device 51, 52. Hold both devices or containers in your hands and pull them apart in a nearly horizontal direction.

Then, each point of action 46 of both levers 4 is pulled by the connecting members 53 and 54, and each point of action 46 is pulled.
2 moves linearly downward on the main body 1. Therefore, each fulcrum 45 moves outward in a direction perpendicular to the axis, and the spacer 3 is also pulled out in the same direction via the pin 29, so that the bifurcated pieces 31a and 31b are removed from the neck 21 of the needle 2. As a result, the needles 2 of the cap opening devices 51 and 52 advance toward the container 60 by the force of the spring 8, and open their seal plates almost simultaneously.

[Effects of the invention] In this invention, levers with a length close to the entire length of the main body of each cap opening device are adopted, and a force point that moves linearly on the outer surface of the main body is provided at one end of these levers, and a lever is provided near each force point. A fulcrum that can move freely in a direction perpendicular to the axis of the needle is provided, and a point of action is placed at the other end, so
A large force can be applied to the fulcrum with a small force,
Therefore, the spacer can be easily pulled out, and since the spacer is restricted to movement in the direction perpendicular to the axis, it does not further distort the spring, which has a large strain energy, unlike the type that swings out, and this also makes it easier to open the plug. The devices can be moved easily, and there is a large degree of freedom in the direction when separating both devices, and it is not necessary to separate them accurately in the horizontal direction.

According to the second aspect, the needle is reliably locked, the lever can be swung without any trouble, and the spacer can be moved smoothly.

According to claim 3, even if the main body has a part with an outer diameter larger than the outer diameter of the part of the main body that the lever's force point comes into contact with, the lever can be attached to the main body while keeping it substantially parallel to the main body axis. , well organized.
