Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a nozzle with a cutter,
In detail, for example, after opening the refill pack spout with the liquid detergent sealed with a provided cutter, the nozzle with the cutter is inserted into the spout to transfer the liquid detergent in the pack to another container well. It relates to a nozzle with a cutter that can be replaced.

[0002]

2. Description of the Related Art In recent years, hand soaps whose properties are liquid,
Body soaps, laundry detergents and the like are filled in various plastic bottles and sold at convenience stores and supermarkets. It is uneconomical to discard these plastic bottles containing a liquid detergent as they are after using them, because this would mean discarding a reusable sturdy container. In addition, this leads to a social problem of increasing the amount of flame-retardant waste that is difficult to dispose of. Incidentally, when this plastic bottle is incinerated in a refuse incinerator at a temperature of about 300 ° C., it generates dioxin, which is recently harmful to the human body.

[0003] Therefore, refillable liquid detergents are commercially available for the purpose of recycling plastic bottles in ordinary households. The liquid detergent is generally filled in a flexible refill pack (fluid storage bag) obtained by laminating a plurality of plastic films into one sheet. At the time of use, open the spout of this pack with fingernails or scissors, then apply the spout to the opening of the plastic bottle, and gradually lift the bottom of the pack while maintaining the unstable hand-held state. By moving, the liquid detergent in this pack is transferred.

[0004]

However, when the liquid detergent is transferred from the conventional refill pack to the plastic bottle, the refill pack is flexible and easily deformed. During the replacement process, it was necessary to hold the pouch sufficiently open with both hands to keep the pack from shaking. Otherwise, the liquid detergent to be poured may not enter the mouth of the bottle well and may spill outside.
In addition, in the case of a refilling pack having a slit that facilitates opening when the spout is opened, the spout can be easily opened by hand using the slit. However, among various refill packs on the market, there are many that have no slit. In such a case, it cannot be opened without cutting with scissors. Therefore, if no scissors were found, this detergent transfer operation could not be performed.

[0005] By the way, in general, the housewife does not waste any liquid detergent remaining in the refill pack after the transfer of the liquid detergent is completed. That is, the soft pack is rolled into a small roll from the bottom, and the remaining liquid detergent is squeezed out, or it is strongly squeezed between the thumb and the forefinger. Such an operation requires a small amount of detergent to be paid in return for labor. Moreover,
In order to forcibly and forcibly crush this almost empty pack, the shoulders of the workers may get stuck, the fingertips may slip from the pack surface during squeezing, hitting the surrounding objects and injuring, There is a concern that the liquid detergent scatters around and stains floors and clothes.

[0006]

SUMMARY OF THE INVENTION Accordingly, the present invention can improve the workability when transferring a fluid from a fluid storage bag to another container, and furthermore, the fluid is less likely to spill out of the container during this transfer operation, and the slit is formed. It is an object of the present invention to provide a nozzle with a cutter that can be easily opened without scissors even with a spout that is not attached and that can be poured out with almost no fluid in the bag by a simple operation. I have.
Another object of the present invention is to provide a nozzle with a cutter that can further facilitate the work of cutting a spout and facilitate the work of drilling a suspension hole in a fluid storage bag. And

[0007]

According to a first aspect of the present invention, a cutter is provided at one end of the nozzle, the cutter being capable of opening a spout of a fluid storage bag containing a fluid, and the other end of the nozzle is provided at the other end of the nozzle. And a cutter-equipped nozzle provided with a hole-forming projection for forming a hanging hole for hanging a bag in a part of the fluid storage bag. The use of the nozzle with a cutter is not limited. For example, it can be used when transferring a fluid stored in a fluid storage bag to another container, or simply when pouring a fluid to a required place. Further, it can be used for opening an arbitrary bag, for example, an envelope or a food pack, or cutting sheets, using only the attached cutter. That is, the nozzle with a cutter has individual uses as a nozzle or a cutter, and has a joint use as a nozzle having a cutter.

[0008] The material of the nozzle with a cutter is not limited. For example, various metals (stainless steel, iron, aluminum, brass, etc.), various synthetic resins (polyvinyl chloride, polypropylene, polyethylene, polystyrene, ABS, etc.), various woods (lauan, beech, oak, cypress, cedar, pine) ,
Various ceramics (alumina, quartz, etc.)
Is mentioned. Further, the thickness (outer diameter) of the nozzle with a cutter is not limited. This is because it is usually necessary to change the thickness of the nozzle in accordance with the size of the spout formed in the fluid storage bag. However, in practice, the size of the spout to be opened is often determined according to the thickness of the nozzle.

The general thickness of this nozzle with a cutter is 6
７０70 mm, preferably 9 好 ま し く 10 mm. If it is less than 6 mm, there is a possibility that the inflow of the fluid cannot be smoothly performed. If it exceeds 70 mm, there is a possibility that an inconvenience that the cutter mounting portion cannot be produced properly may occur. The overall length of the nozzle with a cutter is not limited. However, it is usually 50 to 400 mm, preferably 5 to 400 mm.
0 to 80 mm. If it is less than 50 mm, it is difficult to produce both the attachment portion for the cutter and the attachment portion for the projection for drilling in the nozzle with the cutter because the length is short. In addition, if it exceeds 400 mm, there is a possibility that a disadvantage that it is difficult to handle may occur.

[0010] The fluid mentioned here is not limited. For example,
Liquid detergent (hand soap, body soap, laundry detergent, etc.), liquid cosmetics (skin lotion, hair liquid,
Liquids such as hair restorer, soy sauce, oil, mirin, vinegar, sake, various cooking stocks. In addition, for example, sugar, salt,
Powders such as chemical seasonings and powder cosmetics (various powders and the like) are also included. In the case of such a granular material, it is necessary to increase the nozzle diameter in order to prevent clogging. Further, the fluid storage bag is not limited. For example,
A bag made of a synthetic resin filled with a liquid detergent as described in the section of the prior art, a bag made of paper, or a bag made of various laminated sheets may be used. In short, any bag made of a material that can be cut by a cutter may be used.

Further, the material, size, shape and the like of the cutter are not limited. It is usually made of steel, but may be made of plastic, for example. Also, the installation position of the cutter is
It may be any position as long as it is a nozzle end and does not completely block the space inside the nozzle. The cutter may be provided integrally with the nozzle with the cutter, or may be provided separately.
Furthermore, the material, size, shape, and the like of the drilling projection are not limited. It is only necessary that a suspension hole can be formed in a part of the fluid storage bag. Further, the formation position of the drilling projection is not limited as long as it is the other end of the nozzle. For example, the end surface on the other end side of the nozzle or the outer peripheral surface may be used. Further, the position of the fluid storage bag pierced by the piercing projection is not limited. For example, it may be a glue allowance portion existing at the outer edge portion of the bag or another portion. Of course, the size of the hole formed by the projection is not limited.

According to a second aspect of the present invention, a pair of flexible plate-shaped lips are disposed at one end of the tapered nozzle so as to face each other at a predetermined interval, and the inner surface of one of the lips is provided. The cutter is provided, and on the inner surface of the other lip portion, a blade receiving portion for receiving the cutting edge of the cutter is provided at a position facing the cutter, and the drilling projection is provided with:
The cutter-equipped nozzle according to claim 1, wherein the press-cutting blade is a tapered cutting blade having a fluid flow hole secured and tapered. Both lip portions may be provided integrally with the main body portion of the nozzle, or may be provided separately. Both lips must have some flexibility since they must be cut across the spout between the cutter and the blade receiver. The material, shape, and size of the blade receiving portion are not limited. For example, the blade receiving portion may be provided integrally with the same material as the lip portion, or may be provided separately from another material. The material, shape, size, and the like of the pushing blade provided at the other end of the nozzle are not limited as long as fluid flow holes are secured. For example, it may be provided integrally with the main body of the nozzle, or may be provided separately. Further, the shape may be a tapered cross blade shape, a tapered triangular blade shape, or the like.

[0013]

According to the present invention, the spout is cut by the cutter to open the fluid storage bag. Thus, the spout can be smoothly opened without scissors. Next, one of the ends of the nozzle with a cutter is inserted into the spout. At this time, for example, if the insertion portion of the nozzle is fastened with a fastening band from the outside, it is possible to prevent the fluid from leaking from the gap of the insertion portion of the nozzle when, for example, transferring the fluid. it can. Thereafter, for example, the exposed nozzle end is inserted into an opening of a fluid transfer container prepared in advance. Then, the bottom of the fluid storage bag is gradually lifted. This allows
The fluid in the bag can be transferred to the container through the nozzle with cutter without spilling the fluid from the opening of the container.

For example, if a flexible connection hose is connected to the end of the nozzle with the cutter on the exposed side to extend the connection hose, the transfer operation is further facilitated. That is, since the connection hose is flexible, for example, by pinching the tip of the hose inserted into the container opening with a finger, and appropriately adjusting the degree of the knob of the hose, the flow rate of the fluid flowing through the hose is appropriately adjusted. Can be adjusted. In addition, for example, before the work of cutting the spout, a suspension hole is punched in a part of the fluid storage bag using the drilling projection, and when the remaining amount of the fluid in the bag becomes small, etc. If necessary, the fluid storage bag is suspended upside down through this hole. Thereby, the fluid in the bag slides down the inner surface of the bag by its own weight to the spout, and is transferred to another container through the spout. By using in this way, it is possible to easily pour the liquid in the bag substantially without leaving it, even if the operator does not further work to squeeze out the fluid in the bag.

In particular, according to the second aspect of the present invention, for example, the spout of the fluid storage bag is arranged in the blade receiving portion, and thereafter,
Push both lip portions in the proximity direction with fingers to bring the cutting edge into contact with the spout forming portion, and maintain this state, for example, pulling the fluid storage bag in the cutting direction or moving the nozzle in the cutting direction. Then, the spout is cut by a cutter and opened. With such simple and safe work,
The spout can be opened. In addition, the blade receiving portion of the blade of the cutter is arranged on the inner surface of the one lip portion. As a result, the spout can be cut smoothly while applying the spout to the blade receiving portion. Having such a function, this nozzle with a cutter can also be used as an emergency distribution product in the event of an earthquake. Also, since a beak-shaped push-cutting blade is provided at the other end of the nozzle with a cutter, when drilling a suspension hole in the fluid storage bag, the tip of the push-cutting blade is applied to a predetermined position of the bag. The suspension hole is easily pierced by touching and applying pressure as it is to push it off.

FIG. 10 is an explanatory view showing the nozzle with cutter according to an embodiment of the present invention during drying.

In FIG. 1, reference numeral 10 denotes a nozzle with a cutter. The nozzle 10 with a cutter is a plastic pipe having both ends tapered. The dimensions are 9.5 mm in outer diameter and 70 mm in overall length. At one end of the nozzle with cutter 10, a pair of flexible lip portions 11, 12 in the form of plate pieces are arranged to face each other at a predetermined interval. Between the lip portions 11 and 12, there is formed a flow hole a for the liquid detergent having a small width. On the inner surface of one of the lip portions 11, a cutter 14 for opening a spout 13a of a refill pack 13 (see FIG. 2) in which a liquid detergent is sealed is protruded. In addition, the refill pack 13 is a laminated bag in which a plurality of plastic films are stacked, and the liquid detergent filled therein is reused in an empty plastic bottle B (FIG. 8).
Refill).

The refill pack 13 has no slit near the spout 13a. On the inner surface of the other lip portion 12, a thick blade receiving portion 1 for receiving the cutting edge of the cutter 14 is provided at a position facing the cutter 14.
5 are integrally formed. Next, this nozzle with cutter 1
0, the spout 13a of the refill pack 13
At the approximate center of the edge on the opposite side to the side, a pushing blade 16 (a drilling projection) for punching a hanging hole 13b for hanging the pack.
Are integrally formed. The pushing blade 16 has a tapered cross blade shape, and a gap between the four right-angled triangular plastic plates 16 a serving as the blade edge is formed by the flow of the liquid detergent discharged from the refill pack 13. It becomes hole b.

Next, a method of using the nozzle with cutter 10 according to this embodiment will be described. As shown by the two-dot chain line in FIG. 2, the user first holds the nozzle with cutter 10 with one hand and inserts the tip of the beak-shaped push cutting blade 16 into the refill pack 13.
The hole is pressed almost at the middle of the edge on the side opposite to the spout 13a side to penetrate this edge as it is while gradually increasing the hole. As a result, a suspension hole 13b for suspending the refill pack 13 is formed. in this way,
Since the push cutting blade 16 is integrally formed with the other end of the nozzle 10 with the cutter, the work of suspending the refilling pack 13 and transferring all the liquid detergent inside,
This can be done without using a dangerous drilling tool that may cause injury such as awl.

Next, the opening operation of the refill pack 13 will be described. As shown in FIG. 1 and FIG.
Is placed on the spout 13a of the refill pack 13. Next, both lip portions 11 and 12 are pushed in the direction approaching each other with the thumb and the index finger. Thereby, the cutting edge of the cutter 14 comes into contact with the vicinity of the spout 13 a of the refill pack 13. Subsequently, as shown by the solid line in FIG. 2, the nozzle with cutter 10 is
The cutter 14 cuts the spout 13a and opens it. With the use of the nozzle 10 with a cutter, even if there is no scissors, the spout 1 can be easily operated using the cutter 14 provided as described above.
3a can be cut smoothly.

As shown in FIGS. 3 (a) to 3 (c), the nozzle 10 with a cutter can be used for any type of refill packs 13A to 13C regardless of the type of the spout 13c. To 13e can be cut. further,
The cutter 14 is arranged in a gap between the lip portions 11 and 12 that is so small that a fingertip cannot enter. Therefore, when the spout 13a is cut, there is almost no risk of injury due to the exposed cutter 14. Moreover, since the blade receiving portion 15 is disposed on the inner surface of the one lip portion 12, the spout 13a can be cut smoothly while the spout 13a is being applied to the blade receiving portion 15.

Thereafter, as shown in FIG. 4, one of the ends of the nozzle 10 with a cutter (here, the pushing blade 16 side) is inserted into the opened spout 13a. In addition, cutter 1
The four end portions may be inserted. At this time, as shown in FIG. 5, the insertion portion of the nozzle 10 of the spout 13a is inserted from outside with a plastic fastening band (band with integral screw) 1
Fasten with 7. The fastening band 17 is configured as follows. That is, the fastening band 17 is mainly composed of one long band member 1 having a semicircular cross section and having flexibility.
8, a number of grooves are arranged on the outer periphery at a constant pitch to prevent slippage, and a nut 19 having an inner thread cut in the center hole and a band member 18 are attached to the tip of the band member 18. And a detachment prevention projection 20 having a short trapezoidal cross section for preventing the nut 19 from coming off. By providing the detachment prevention projection 20, each component of the fastening band 17 is less likely to be lost.

As shown in the partially enlarged view of FIG. 5, when the band member 18 is pressed and bent into a ring shape, the ends having the semicircular cross-sections are fitted to each other, so that the band member 18 is small. The column can be assembled. In addition, the outer threads at both ends of the band member 18 are engraved on the outer peripheral surfaces at both ends so that one outer thread 18a is formed only in this cylindrical state. If the distal ends of the band member 18 bent in a ring shape are bonded to each other, heated and welded, or are integrally formed, the detachment prevention projection 20 becomes unnecessary. Further, the fastening band 17 can be changed to a plastic fastening band 17A of another structure shown in FIG. That is,
As shown in FIG. 6A, this fastening band 17A
One end of a flat and elongated band member 22 is fixed to the head of the bolt 21 and the band member 22 is pressed and bent into a ring shape as shown in FIG. And the band member 2
2 is inserted into the bolt 21 with a bolt hole 22a drilled at the front end thereof, and then a nut 23 with an internal thread is bolted to the bolt 21.
By screwing into this, the spout 13a of the refill pack 13 is fastened to the nozzle 10 with the cutter. The nut 23 is prevented from being detached and lost by attaching the detachment prevention projection 20 to the tip of the bolt 21. Note that the detachment prevention projection 20 is
1 and may be integrally formed.

As described above, using the fastening band 17 (the same applies to the fastening band 17A, the same applies hereinafter), the spout 1
Since the liquid detergent 3a is fixed to the outer peripheral surface of the nozzle with cutter 10 in a state of close contact, it is possible to prevent the liquid detergent from leaking from the gap at the insertion portion of the nozzle 10 when the liquid detergent is transferred. Subsequently, as shown in FIG.
One end of a connection hose 24 having a length of 100 mm is extrapolated to the end of the nozzle with cutter 10 protruding outward from 3a on the cutter 14 side. The connecting hose 24 is made of a soft plastic, and of course, has an inner diameter of 10 mm which is the same as or slightly larger than the outer diameter of the nozzle 10 with a cutter so as to be in close contact with the nozzle end and not easily come off.
If the diameter of the connection hose 24 is slightly larger than the outer diameter of the nozzle, a part of the formation part of the spout 13a is pressed into the end of the hose simultaneously with the connection of the hose to the nozzle 10 with the cutter. The connection hose 24 can be used instead of the fastening band 17. Thereby, the fastening band 17 becomes unnecessary. Further, in this embodiment, in order to further enhance the effect of preventing the connection hose 24 from coming off, another separate fastening band 17 is used.
The base of the connection hose 24 is fastened to the end of the nozzle with cutter 10 on the cutter 14 side. The connection hose 24
So that the connection hose 24
May be integrated with the nozzle with cutter 10 by thermocompression bonding or the like. Further, the fastening band 17 may be integrated with the connection hose 24 in advance.

Next, as shown in FIG. 8, the distal end of the connection hose 24 is bent and inserted into the opening of the plastic bottle B. This state is maintained by holding the opening of the bottle with the palm and holding the tip of the connection hose 24 with the thumb and forefinger. After that, when the bottom of the refill pack 13 is gradually lifted,
The replenishing liquid detergent filled in the pack 13 is poured into the inside of the plastic bottle B from the bottle opening via the spout 13 a, the nozzle with cutter 10, and the connection hose 24 to be replenished. Thus, the fluid in the bag can be transferred to the container through the nozzle with cutter without spilling the fluid from the opening of the container. If the liquid detergent still remains in the refill pack 13 even after the replenishment is completed, or if the liquid detergent has a good wrinkle, a force is applied to the thumb and forefinger gripping the connection hose 24, and With your finger.
Thereby, the pouring of the detergent is stopped. Thereafter, the hose tip is pulled out of the plastic bottle B, the pack 13 is returned to its original state, and the finger is released from the connection hose 24. In addition,
Instead of connecting the connecting hose 24 to the exposed end of the nozzle 10 with the cutter, the liquid detergent may be poured directly from the exposed end.

When most of the liquid detergent has been poured out, next, an operation of removing a small amount of the liquid detergent remaining in the refill pack 13 is performed. That is, as shown in FIG.
An S-shaped hook 25 is provided in the hanging hole 13b of the refill pack 13.
Is hooked, and the other end of the S-shaped hook 25 is hung on the hanging bar 26. At this time, the distal end of the connection hose 24 facing downward is inserted into the opening of the plastic bottle B. If left as it is for a while, the liquid detergent remaining in the refill pack 13 will gradually fall into the bottle B along the inner surface of the pack. By using in this way, even if the worker does not further work to round and squeeze out the liquid detergent in the refill pack 13, it is possible to easily transfer the detergent in the pack to the plastic bottle B without substantially leaving the detergent. Can be. The outer diameter of the nozzle with cutter 10 is substantially the same as the hole diameter of the spout 13a. Thus, the nozzle 10 can be used like an extension pipe of the spout 13a. Further, in the nozzle with cutter 10 of this embodiment, since the connecting hose 24 is connected to the end of the nozzle 10 on the exposed side and extended, the transfer operation is further facilitated.

The nozzle with cutter 10 can be washed after use, dried on the sun, and reused many times. At this time, as shown in FIG. 10 (particularly, see a partially enlarged view of FIG. 10), if a hook hole 27a is bored in an outer peripheral portion of a nut 27 constituting a part of the fastening band 17B, the hook hole 27a is formed. Hook one end of a small S-shaped hook 28 onto 27a, this nozzle 10 and each accessory 1
7, 17B, and 24 can be collectively hung on the hanging bar 26 and dried. In addition, subsequent storage becomes easier. Thereby, there is no need to separately dry the nozzle 10 and the attached parts 17, 17B, 24, and the risk of parts being lost during drying and storage is reduced.

[0028]

According to the present invention, the cutter is provided at one end of the nozzle and the projection for piercing is provided at the other end of the nozzle. Therefore, for example, when the fluid is transferred from the fluid storage bag to another container. , Its workability can be improved. Moreover, it is possible to prevent the fluid from spilling out of the container during the transfer operation. Furthermore, the spout without a slit can be easily opened without preparing scissors. Then, it is possible to pour out the liquid in the fluid storage bag substantially without leaving the liquid simply by performing a simple drilling operation.

In particular, according to the second aspect of the present invention, both end portions of the nozzle are tapered, and a pair of lip portions having a cutter and a blade receiving portion are provided at one end of the nozzles. In addition, since a push-cutting blade is provided at the other end to pierce the suspension hole in the fluid storage bag, the work of cutting the spout can be facilitated. In addition, the work of drilling the suspension holes can be facilitated.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a nozzle with a cutter,
In detail, for example, after opening the refill pack spout with the liquid detergent sealed with a provided cutter, the nozzle with the cutter is inserted into the spout to transfer the liquid detergent in the pack to another container well. It relates to a nozzle with a cutter that can be replaced.

[0002]

2. Description of the Related Art In recent years, hand soaps whose properties are liquid,
Body soaps, laundry detergents and the like are filled in various plastic bottles and sold at convenience stores and supermarkets. It is uneconomical to discard these plastic bottles containing a liquid detergent as they are after using them, because this would mean discarding a reusable sturdy container. In addition, this leads to a social problem of increasing the amount of flame-retardant waste that is difficult to dispose of. Incidentally, when this plastic bottle is incinerated in a refuse incinerator at a temperature of about 300 ° C., it generates dioxin, which is recently harmful to the human body.

[0003] Therefore, refillable liquid detergents are commercially available for the purpose of recycling plastic bottles in ordinary households. The liquid detergent is generally filled in a flexible refill pack (fluid storage bag) obtained by laminating a plurality of plastic films into one sheet. At the time of use, open the spout of this pack with fingernails or scissors, then apply the spout to the opening of the plastic bottle, and gradually lift the bottom of the pack while maintaining the unstable hand-held state. By moving, the liquid detergent in this pack is transferred.

[0004]

However, when the liquid detergent is transferred from the conventional refill pack to the plastic bottle, the refill pack is flexible and easily deformed. During the replacement process, it was necessary to hold the pouch sufficiently open with both hands to keep the pack from shaking. Otherwise, the liquid detergent to be poured may not enter the mouth of the bottle well and may spill outside.
In addition, in the case of a refilling pack having a slit that facilitates opening when the spout is opened, the spout can be easily opened by hand using the slit. However, among various refill packs on the market, there are many that have no slit. In such a case, it cannot be opened without cutting with scissors. Therefore, if no scissors were found, this detergent transfer operation could not be performed.

[0005] By the way, in general, the housewife does not waste any liquid detergent remaining in the refill pack after the transfer of the liquid detergent is completed. That is, the soft pack is rolled into a small roll from the bottom, and the remaining liquid detergent is squeezed out, or it is strongly squeezed between the thumb and the forefinger. Such an operation requires a small amount of detergent to be paid in return for labor. Moreover,
In order to forcibly and forcibly crush this almost empty pack, the shoulders of the workers may get stuck, the fingertips may slip from the pack surface during squeezing, hitting the surrounding objects and injuring, There is a concern that the liquid detergent scatters around and stains floors and clothes.

[0006]

SUMMARY OF THE INVENTION Accordingly, the present invention can improve the workability when transferring a fluid from a fluid storage bag to another container, and furthermore, the fluid is less likely to spill out of the container during this transfer operation, and the slit is formed. A spout can be easily opened without scissors even without a spout, and it is possible to pour out almost no fluid in the bag with a simple operation, and also to pierce a suspension hole in the fluid storage bag. An object of the present invention is to provide a nozzle with a cutter capable of facilitating work. Another object of the present invention is to provide a nozzle with a cutter that can further facilitate the work of cutting a spout.

[0007]

According to the first aspect of the present invention, a cutter is provided at one end of a nozzle, which can open a spout by cutting a part of a fluid storage bag in which a fluid is stored. The nozzle with a cutter is provided at the other end of the nozzle with a projection for making a hole for hanging a bag from a part of the fluid storage bag. The use of the nozzle with a cutter is not limited. For example, it can be used when transferring a fluid stored in a fluid storage bag to another container, or simply when pouring a fluid to a required place. Further, it can be used for opening an arbitrary bag, for example, an envelope or a food pack, or cutting sheets, using only the attached cutter. That is, the nozzle with a cutter has individual uses as a nozzle or a cutter, and has a joint use as a nozzle having a cutter.

[0008] The material of the nozzle with a cutter is not limited. For example, various metals (stainless steel, iron, aluminum, brass, etc.), various synthetic resins (polyvinyl chloride, polypropylene, polyethylene, polystyrene, ABS, etc.), various woods (lauan, beech, oak, cypress, cedar, pine) ,
Various ceramics (alumina, quartz, etc.)
Is mentioned. Further, the thickness (outer diameter) of the nozzle with a cutter is not limited. This is because it is usually necessary to change the thickness of the nozzle in accordance with the size of the spout formed in the fluid storage bag. However, in practice, the size of the spout to be opened is often determined according to the thickness of the nozzle.

The general thickness of this nozzle with a cutter is 6
７０70 mm, preferably 9 好 ま し く 10 mm. If it is less than 6 mm, there is a possibility that the inflow of the fluid cannot be smoothly performed. If it exceeds 70 mm, there is a possibility that an inconvenience that the cutter mounting portion cannot be produced properly may occur. The overall length of the nozzle with a cutter is not limited. However, it is usually 50 to 400 mm, preferably 5 to 400 mm.
0 to 80 mm. If it is less than 50 mm, it is difficult to produce both the attachment portion for the cutter and the attachment portion for the projection for drilling in the nozzle with the cutter because the length is short. In addition, if it exceeds 400 mm, there is a possibility that a disadvantage that it is difficult to handle may occur.

[0010] The fluid mentioned here is not limited. For example,
Liquid detergent (hand soap, body soap, laundry detergent, etc.), liquid cosmetics (skin lotion, hair liquid,
Liquids such as hair restorer, soy sauce, oil, mirin, vinegar, sake, various cooking stocks. In addition, for example, sugar, salt,
Powders such as chemical seasonings and powder cosmetics (various powders and the like) are also included. In the case of such a granular material, it is necessary to increase the nozzle diameter in order to prevent clogging. Further, the fluid storage bag is not limited. For example,
A bag made of a synthetic resin filled with a liquid detergent as described in the section of the prior art, a bag made of paper, or a bag made of various laminated sheets may be used. In short, any bag made of a material that can be cut by a cutter may be used.

Further, the material, size, shape and the like of the cutter are not limited. It is usually made of steel, but may be made of plastic, for example. Also, the cutter may be attached at one end of the nozzle and at a position that does not completely block the space inside the nozzle. The cutter may be provided integrally with the nozzle with the cutter, or may be provided separately. Furthermore, the material, size, shape, and the like of the drilling projection are not limited. It is only necessary that a suspension hole can be formed in a part of the fluid storage bag. Further, the formation position of the drilling projection is not limited as long as it is the other end of the nozzle. For example, it may be the end on the other end side of the nozzle or the outer peripheral surface. Further, the position of the fluid storage bag pierced by the piercing projection is not limited. For example, it may be a glue allowance portion existing at the outer edge portion of the bag or another portion. Of course, the size of the hole formed by the projection is not limited.

According to a second aspect of the present invention, a cutter is provided at one end of the nozzle and capable of opening a spout of a fluid storage bag containing a fluid, and a part of the fluid storage bag is provided at the other end of the nozzle. A nozzle having a cutter provided with a hole-piercing projection for piercing a hanging hole for hanging a bag, wherein one end of the tapered nozzle has a pair of flexible plate-shaped lip portions. The cutter is provided on the inner surface of one of the lip portions, and the cutter receiver is provided on the inner surface of the other lip portion at a position opposed to the cutter to receive the cutting edge of the cutter. The hole-forming projection is a nozzle with a cutter, which is a push-cutting blade that is tapered by securing a fluid flow hole. Both lip portions may be provided integrally with the main body portion of the nozzle, or may be provided separately. Both lips must have some flexibility since they must be cut across the spout between the cutter and the blade receiver. The material, shape, and size of the blade receiving portion are not limited. For example, the blade receiving portion may be provided integrally with the same material as the lip portion, or may be provided separately from another material. The material, shape, size, and the like of the pushing blade provided at the other end of the nozzle are not limited as long as fluid flow holes are secured. For example, it may be provided integrally with the main body of the nozzle, or may be provided separately. Further, the shape may be a tapered cross blade shape, a tapered triangular blade shape, or the like.

[0013]

According to the present invention, a part of the bag is cut by the cutter to open the fluid storage bag. Thus, the spout can be smoothly opened without scissors. Next, one of the ends of the nozzle with a cutter is inserted into the spout. At this time, for example, if the insertion portion of the nozzle is fastened with a fastening band from the outside, it is possible to prevent the fluid from leaking from the gap of the insertion portion of the nozzle when, for example, transferring the fluid. it can. Thereafter, for example, the exposed nozzle end is inserted into an opening of a fluid transfer container prepared in advance. Then, the bottom of the fluid storage bag is gradually lifted. This allows
The fluid in the bag can be transferred to the container through the nozzle with cutter without spilling the fluid from the opening of the container.

For example, if a flexible connection hose is connected to the end of the nozzle with the cutter on the exposed side to extend the connection hose, the transfer operation is further facilitated. That is, since the connection hose is flexible, for example, by pinching the tip of the hose inserted into the container opening with a finger, and appropriately adjusting the degree of the knob of the hose, the flow rate of the fluid flowing through the hose is appropriately adjusted. Can be adjusted. In addition, for example, before the work of cutting the spout, a suspension hole is punched in a part of the fluid storage bag using the drilling projection, and when the remaining amount of the fluid in the bag becomes small, etc. If necessary, the fluid storage bag is suspended upside down through this hole. Thereby, the fluid in the bag slides down the inner surface of the bag by its own weight to the spout, and is transferred to another container through the spout. By using in this way, it is possible to easily pour the liquid in the bag substantially without leaving it, even if the operator does not further work to squeeze out the fluid in the bag.

In particular, according to the second aspect of the present invention, for example, the spout of the fluid storage bag is arranged in the blade receiving portion, and thereafter,
Push both lip portions in the proximity direction with fingers to bring the cutting edge into contact with the spout forming portion, and maintain this state, for example, pulling the fluid storage bag in the cutting direction or moving the nozzle in the cutting direction. Then, the spout is cut by a cutter and opened. With such simple and safe work,
The spout can be opened. In addition, the blade receiving portion of the blade of the cutter is arranged on the inner surface of the one lip portion. As a result, the spout can be cut smoothly while applying the spout to the blade receiving portion. Having such a function, this nozzle with a cutter can also be used as an emergency distribution product in the event of an earthquake. Also, since a beak-shaped push-cutting blade is provided at the other end of the nozzle with a cutter, when drilling a suspension hole in the fluid storage bag, the tip of the push-cutting blade is applied to a predetermined position of the bag. The suspension hole is easily pierced by touching and applying pressure as it is to push it off.

FIG. 10 is an explanatory view showing the nozzle with cutter according to an embodiment of the present invention during drying.

In FIG. 1, reference numeral 10 denotes a nozzle with a cutter. The nozzle 10 with a cutter is a plastic pipe having both ends tapered. The dimensions are 9.5 mm in outer diameter and 70 mm in overall length. At one end of the nozzle with cutter 10, a pair of flexible lip portions 11, 12 in the form of plate pieces are arranged to face each other at a predetermined interval. Between the lip portions 11 and 12, there is formed a flow hole a for the liquid detergent having a small width. On the inner surface of one of the lip portions 11, a cutter 14 for opening a spout 13a of a refill pack 13 (see FIG. 2) in which a liquid detergent is sealed is protruded. In addition, the refill pack 13 is a laminated bag in which a plurality of plastic films are stacked, and the liquid detergent filled therein is reused in an empty plastic bottle B (FIG. 8).
Refill).

The refill pack 13 has no slit near the spout 13a. On the inner surface of the other lip portion 12, a thick blade receiving portion 1 for receiving the cutting edge of the cutter 14 is provided at a position facing the cutter 14.
5 are integrally formed. Next, this nozzle with cutter 1
0, the spout 13a of the refill pack 13
At the approximate center of the edge on the opposite side to the side, a pushing blade 16 (a drilling projection) for punching a hanging hole 13b for hanging the pack.
Are integrally formed. The pushing blade 16 has a tapered cross blade shape, and a gap between the four right-angled triangular plastic plates 16 a serving as the blade edge is formed by the flow of the liquid detergent discharged from the refill pack 13. It becomes hole b.

Next, a method of using the nozzle with cutter 10 according to this embodiment will be described. As shown by the two-dot chain line in FIG. 2, the user first holds the nozzle with cutter 10 with one hand and inserts the tip of the beak-shaped push cutting blade 16 into the refill pack 13.
The hole is pressed almost at the middle of the edge on the side opposite to the spout 13a side to penetrate this edge as it is while gradually increasing the hole. As a result, a suspension hole 13b for suspending the refill pack 13 is formed. in this way,
Since the push cutting blade 16 is integrally formed with the other end of the nozzle 10 with the cutter, the work of suspending the refilling pack 13 and transferring all the liquid detergent inside,
This can be done without using a dangerous drilling tool that may cause injury such as awl.

Next, the opening operation of the refill pack 13 will be described. As shown in FIG. 1 and FIG.
Is placed on the spout 13a of the refill pack 13. Next, both lip portions 11 and 12 are pushed in the direction approaching each other with the thumb and the index finger. Thereby, the cutting edge of the cutter 14 comes into contact with the vicinity of the spout 13 a of the refill pack 13. Subsequently, as shown by the solid line in FIG. 2, the nozzle with cutter 10 is
The cutter 14 cuts the spout 13a and opens it. With the use of the nozzle 10 with a cutter, even if there is no scissors, the spout 1 can be easily operated using the cutter 14 provided as described above.
3a can be cut smoothly.

As shown in FIGS. 3 (a) to 3 (c), the nozzle 10 with a cutter can be used for any type of refill packs 13A to 13C regardless of the type of the spout 13c. To 13e can be cut. further,
The cutter 14 is arranged in a gap between the lip portions 11 and 12 that is so small that a fingertip cannot enter. Therefore, when the spout 13a is cut, there is almost no risk of injury due to the exposed cutter 14. Moreover, since the blade receiving portion 15 is disposed on the inner surface of the one lip portion 12, the spout 13a can be cut smoothly while the spout 13a is being applied to the blade receiving portion 15.

Thereafter, as shown in FIG. 4, one of the ends of the nozzle 10 with a cutter (here, the pushing blade 16 side) is inserted into the opened spout 13a. In addition, cutter 1
The four end portions may be inserted. At this time, as shown in FIG. 5, the insertion portion of the nozzle 10 of the spout 13a is inserted from outside with a plastic fastening band (band with integral screw) 1
Fasten with 7. The fastening band 17 is configured as follows. That is, the fastening band 17 is mainly composed of one long band member 1 having a semicircular cross section and having flexibility.
8, a number of grooves are arranged on the outer periphery at a constant pitch to prevent slippage, and a nut 19 having an inner thread cut in the center hole and a band member 18 are attached to the tip of the band member 18. And a detachment prevention projection 20 having a short trapezoidal cross section for preventing the nut 19 from coming off. By providing the detachment prevention projection 20, each component of the fastening band 17 is less likely to be lost.

As shown in the partially enlarged view of FIG. 5, when the band member 18 is pressed and bent in a ring shape, the ends each having a semicircular cross section are joined to each other to form a small band member. The column can be assembled. In addition, the outer threads at both ends of the band member 18 are engraved on the outer peripheral surfaces at both ends so that one outer thread 18a is formed only in this cylindrical state. If the distal ends of the band member 18 bent in a ring shape are bonded to each other, heated and welded, or are integrally formed, the detachment prevention projection 20 becomes unnecessary. Further, the fastening band 17 can be changed to a plastic fastening band 17A of another structure shown in FIG. That is,
As shown in FIG. 6A, this fastening band 17A
One end of a flat and elongated band member 22 is fixed to the head of the bolt 21 and the band member 22 is pressed and bent into a ring shape as shown in FIG. And the band member 2
2 is inserted into the bolt 21 with a bolt hole 22a drilled at the front end thereof, and then a nut 23 with an internal thread is bolted to the bolt 21.
By screwing into this, the spout 13a of the refill pack 13 is fastened to the nozzle 10 with the cutter. The nut 23 is prevented from being detached and lost by attaching the detachment prevention projection 20 to the tip of the bolt 21. Note that the detachment prevention projection 20 is
1 and may be integrally formed.

As described above, using the fastening band 17 (the same applies to the fastening band 17A, the same applies hereinafter), the spout 1
Since the liquid detergent 3a is fixed to the outer peripheral surface of the nozzle with cutter 10 in a state of close contact, it is possible to prevent the liquid detergent from leaking from the gap at the insertion portion of the nozzle 10 when the liquid detergent is transferred. Subsequently, as shown in FIG.
One end of a connection hose 24 having a length of 100 mm is extrapolated to the end of the nozzle with cutter 10 protruding outward from 3a on the cutter 14 side. The connecting hose 24 is made of a soft plastic, and of course, has an inner diameter of 10 mm which is the same as or slightly larger than the outer diameter of the nozzle 10 with a cutter so as to be in close contact with the nozzle end and not easily come off.
When the diameter of the connection hose 24 is slightly larger than the outer diameter of the nozzle, a part of the spout 13a is press-fitted into the end of the hose at the same time when the hose is connected to the cutter nozzle 10. The connection hose 24 can be used instead of the fastening band 17. Thereby, the fastening band 17 becomes unnecessary. Further, in this embodiment, in order to further enhance the effect of preventing the connection hose 24 from coming off, another separate fastening band 17 is used.
The base of the connection hose 24 is fastened to the end of the nozzle with cutter 10 on the cutter 14 side. The connection hose 24
So that the connection hose 24
May be integrated with the nozzle with cutter 10 by thermocompression bonding or the like. Further, the fastening band 17 may be integrated with the connection hose 24 in advance.

Next, as shown in FIG. 8, the distal end of the connection hose 24 is bent and inserted into the opening of the plastic bottle B. This state is maintained by holding the opening of the bottle with the palm and holding the tip of the connection hose 24 with the thumb and forefinger. After that, when the bottom of the refill pack 13 is gradually lifted,
The replenishing liquid detergent filled in the pack 13 is poured into the inside of the plastic bottle B from the bottle opening via the spout 13 a, the nozzle 10 with the cutter, and the connection hose 24, and replenished. Thus, the fluid in the bag can be transferred to the container through the nozzle with cutter without spilling the fluid from the opening of the container. If the liquid detergent still remains in the refill pack 13 even after the replenishment is completed, or if the liquid detergent has a good wrinkle, a force is applied to the thumb and forefinger gripping the connection hose 24, and With your finger.
Thereby, the pouring of the detergent is stopped. Thereafter, the hose tip is pulled out of the plastic bottle B, the pack 13 is returned to its original state, and the finger is released from the connection hose 24. In addition,
Instead of connecting the connecting hose 24 to the exposed end of the nozzle 10 with the cutter, the liquid detergent may be poured directly from the exposed end.

When most of the liquid detergent has been poured out, next, an operation of removing a small amount of the liquid detergent remaining in the refill pack 13 is performed. That is, as shown in FIG.
An S-shaped hook 25 is provided in the hanging hole 13b of the refill pack 13.
Is hooked, and the other end of the S-shaped hook 25 is hung on the hanging bar 26. At this time, the distal end of the connection hose 24 facing downward is inserted into the opening of the plastic bottle B. If left as it is for a while, the liquid detergent remaining in the refill pack 13 will gradually fall into the bottle B along the inner surface of the pack. By using in this way, even if the worker does not further work to round and squeeze out the liquid detergent in the refill pack 13, it is possible to easily transfer the detergent in the pack to the plastic bottle B without substantially leaving the detergent. Can be. The outer diameter of the nozzle with cutter 10 is substantially the same as the hole diameter of the spout 13a. Thus, the nozzle 10 can be used like an extension pipe of the spout 13a. Further, in the nozzle with cutter 10 of this embodiment, since the connecting hose 24 is connected to the end of the nozzle 10 on the exposed side and extended, the transfer operation is further facilitated.

The nozzle with cutter 10 can be washed after use, dried on the sun, and reused many times. At this time, as shown in FIG. 10 (particularly, see a partially enlarged view of FIG. 10), if a hook hole 27a is bored in an outer peripheral portion of a nut 27 constituting a part of the fastening band 17B, the hook hole 27a is formed. Hook one end of a small S-shaped hook 28 onto 27a, this nozzle 10 and each accessory 1
7, 17B, and 24 can be collectively hung on the hanging bar 26 and dried. In addition, subsequent storage becomes easier. Thereby, there is no need to separately dry the nozzle 10 and the attached parts 17, 17B, 24, and the risk of parts being lost during drying and storage is reduced.

[0028]

According to the first aspect of the present invention, the cutter is provided at one end of the nozzle, and the projection for piercing is provided at the other end of the nozzle. When the fluid is transferred, the workability can be improved. Moreover, it is possible to prevent the fluid from spilling out of the container during the transfer operation. Furthermore, the spout without a slit can be easily opened without preparing scissors. Then, it is possible to pour out the liquid in the fluid storage bag substantially without leaving the liquid simply by performing a simple drilling operation.

In particular, according to the second aspect of the present invention, both end portions of the nozzle are tapered, and a pair of lip portions having a cutter and a blade receiving portion are provided at one end of the nozzles. In addition, since a push-cutting blade is provided at the other end to pierce the suspension hole in the fluid storage bag, the work of cutting the spout can be facilitated. In addition, the work of drilling the suspension holes can be facilitated.
