Description

  The present invention relates to a gun-type dispenser, and more specifically, a gun-type dispenser that can always pour out a predetermined amount of a viscous liquid material in a bag, and has a boomerang-shaped cutting blade fitted to the spout portion. It is related with the gun-type dispenser made into the structure where a spout part is not obstruct | occluded by the bending | flexion and twist of the said bag during a pouring operation.

Traditionally, mass-market outlets for edible foods such as hamburgers, hot dogs, pizzas, etc. have used gun-type dispensers with various structures for topping viscous liquids such as mayonnaise, ketchup, mustard, and various creams. It is used as a good pouring tool.
For example, in Patent Document 1 (Japanese Patent Laid-Open No. 59-98767) and Patent Document 2 (Japanese Patent No. 2944116), a viscous liquid material in a bag having a specific shape suitable for a bag (cartridge) housing portion of a gun-type dispenser is dispenser. It is described that it will be poured out.

These techniques described in the above documents have disadvantages in terms of economic cost because the shape of the bag (hereinafter also referred to as “pouch”) is a special shape, and the corner tip of the bag protrudes from the spout portion of the dispenser during use. In addition, there is a troublesome work of cutting out the tip portion with scissors and then performing the pouring work, and the surroundings of the work are easily soiled and unsanitary.

Therefore, as a technique for solving the above-mentioned problem, the present inventor firstly described a pouch of an inexpensive general commercial product as a bag type, for example, a flat pouch or the like, in which a viscous liquid material is sealed and filled. A viscous liquid material that is loaded into a gun-type dispenser, and a pouch is formed in advance by inserting a cylindrical jig having a pointed end from the dispenser outlet at the time of dispensing. Invented the method and filed a patent application (Japanese Patent Application No. 2006-025094).

JP 59-98767 Japanese Patent No. 2944116

However, the method of pouring the viscous liquid material is excellent in terms of economic cost by using a pouch that has been generally used, but the pouch material (hard and soft) and the film constituting the pouch It has been found that depending on the thickness, it is difficult to always dispense a predetermined amount.

In particular, this tendency is more difficult to maintain a predetermined amount of pouring as the material of the bag is soft polyethylene and the material is thinner. In order to find out the reason, the present inventor investigated the main cause, and further conducted a pouring test with various pouches. Then, when the other end of the pouch is continuously pushed in with the piston while the dispenser is operated, the pouch film is bent, and this bent film increases, so that the break opening formed in the pouch in advance is closed. As a result, it was found that the amount dispensed could not be kept constant. In addition, even when the break opening of the pouch and the spout of the cylindrical body are matched at the start of pouring, the pouch may be twisted by pushing the piston, and the break opening of the pouch and the spout It has been found that one of the factors is that the position of the portion is displaced, and as a result, the opening portion of the fracture is closed, and the viscous liquid material cannot be poured out sufficiently.

The present invention has been made in consideration of such knowledge and knowledge, and is generally used in terms of economic cost by disposing a substantially boomerang-shaped cutting blade at the spout of the gun-type dispenser. It is an object of the present invention to provide a gun-type dispenser that can accurately dispense a predetermined amount of a viscous liquid filled in a pouch without delay during the dispensing operation.

That is, the gun type dispenser of the present invention is
A cylindrical body that can accommodate a bag filled with a viscous liquid as densely as possible and whose both ends are open, an accommodating portion that can accommodate the cylindrical body, and the bag at one end in the cylindrical body In a gun-type dispenser having a piston that is pushed to the outlet port on the side and pushed into the bag until the inner volume of the bag is almost eliminated, and an operation unit that pushes the piston rod equipped with the piston by a predetermined amount within the cylindrical body,
A substantially boomerang-shaped cutting blade is bridged at one end side spout portion of the tubular body with a sharp end directed inward of the tubular body, and a fixing member for fixing the cutting blade is fitted to the spout portion. It is characterized by being.

In the present invention, the substantially boomerang-shaped cutting blade means, for example, that two cutting blades are left from a blade member with two sides on the both ends of the pointed portion of the substantially triangular plate material, and the area is smaller than this. It refers to the shape of the remaining blade member that is formed by cutting out a similar triangular area.

By setting the blade member in such a shape, a bag (pouch) filled with a viscous liquid material pushed into the cylindrical body by the piston is opened at the tip of the cutting blade and is triangular on the bottom side of the blade member. It becomes the state which has the shape space | gap (space), and is opposed to the spout part of the said cylindrical body.
As a result, a flexible portion of the bag is generated in the middle of the pouring, and even if this is pushed toward the pouring port, it does not close all the triangular gaps, and the viscous liquid in the bag is the opening of the bag. To the spout portion through the gap and can be poured out as it is.

In addition, since the tip of the boomerang-shaped cutting blade is stuck in the break opening of the bag, the bag is twisted in the tubular body during the pouring and the bag break opening and the spout of the tubular body This eliminates the phenomenon that the spout is blocked by this position.

At this time, if a fixing member for fixing the cutting blade is fitted with an annular cap, the cutting blade can be removed and replaced if necessary. In addition, when the fixing member is a cap having at least one or more cross slits formed on the top surface thereof, the viscous liquid material to be poured out can be poured out over a wide range by a single extrusion operation of the dispenser. Of course, screwing, fitting, etc. are included as fitting.
Also, in the present invention, depending on the viscosity of the viscous liquid material, the shape of the cutting blade is a boomerang-shaped cutting blade, or the film member in which at least one or more slits are formed with the fixing member as an annular cap is cylindrical. It is good also as a structure fixed to the spout part of a body.

As described above, the gun-type dispenser of the present invention bridges a substantially boomerang-shaped cutting blade having a pointed end toward the inside of the cylindrical body at one end side outlet of the cylindrical body housed in the gun-type dispenser. In addition, since the fixing member for fixing the cutting blade is fitted to the spout portion, the dispenser can dispense a normal bag-like viscous liquid material with excellent economic cost, and the bag. Therefore, the spout portion is not blocked by bending or twisting, and a predetermined amount of viscous liquid material can be poured out without stagnation.

Further, since the cutting blade is fitted with a fixing member, the cutting blade can be easily replaced and cleaned as necessary. At this time, the fixing member is a cap having one or more slits formed on the top surface, or a film member having one or more slits formed on the top surface portion as an annular cap is fixed. Can be dispensed in a wide range by a single extrusion operation of the dispenser, so that it can be provided as a dispenser with excellent work efficiency.

[Example 1]
In FIG. 1, a gun-type dispenser 1 accommodates a cylindrical body 2 made of a hard material that can accommodate a bag A filled with a viscous liquid as close as possible and is opened at both ends, and the cylindrical body 2. A container 3 that can be used, a piston 4 that pushes the bag A into the spout portion 21 on one end side in the cylindrical body 2 and pushes the bag A until the inner volume of the bag A substantially disappears, and the piston 4 is mounted. And an operating portion 6 that pushes the piston rod 5 by a predetermined amount within the cylindrical body 2. The one end side spout portion 21 of the tubular body 2 is bridged with a substantially boomerang-shaped cutting blade 8 with the tip end portion 7 facing inward of the tubular body 2, and the cutting blade 8 is connected to the spout 8. The structure can be fixed by a fixing member 9 that can be screwed to the portion 21.

When using this gun-type dispenser, a film member 11 having at least one slit 10 is usually sandwiched between the cutting blade 8 attached to the spout 21 and the fitting cap 9 (FIG. 8, (See FIG. 9). Moreover, a normal cap can be directly used instead of the annular cap 9 as a fixing member for fixing the cutting blade 8 due to the difference in viscosity of the viscous liquid material. In that case, it goes without saying that the top surface of the cap with the slit 10 can be used (see FIG. 12).

Next, the operation of the present invention will be described based on examples.
Since the gun-type dispenser 1 of the present embodiment has the above-described structure, the bag A filled with the viscous liquid material is accommodated in the cylindrical body 2, and the cylindrical body 2 is accommodated in the accommodating portion 3 of the gun-type dispenser 1. Installing. Subsequently, by operating the trigger 61 of the operation part 6 of the gun-type dispenser 1, the piston 4 is pushed toward the spout part 21 on one end side in the cylindrical body 2. By pushing the piston 4, the bag A in the cylindrical body 2 is broken and opened from the cut portion bridged by the spout portion 21. In the present embodiment, the fitting structure of the fixing member 9 is shown as being screwed, but it goes without saying that it can be of a fitting type (fitting).

Furthermore, by continuing to push the piston 4, the viscous liquid material in the bag A is poured out of the gun-type dispenser 1 from the opening of the bag A via the side of the cutting blade 8. At this time, since the cutting blade 8 has a substantially boomerang shape with a gap in the bottom surface thereof, the viscous liquid material passes through the gap and is smoothly poured out.
Further, even if the piston 4 is repeatedly pushed, the cutting blade 8 is stuck into the bag A, so that the gap is always maintained and the bag A is not twisted, thereby preventing the breaking opening from being blocked. .

In carrying out the present invention, the piston 4 is pushed until the inner volume of the bag A is almost eliminated, so that the pushing surface of the piston 4 and the tip 7 of the cutting blade 8 come into contact with each other, and the piston 4 cannot be pushed. Thus, the viscous liquid may remain in the bag A.
Accordingly, in the present invention and the embodiment, in consideration of this, in order to prevent the viscous liquid material from remaining in the bag A, the pointed portion 7 of the cutting blade 8 and the like is accommodated on the feeding surface of the bag A of the piston 4. The groove 12 is formed in advance so that the pushing surface of the piston 4 and the spout 21 of the cylindrical body 2 can be approached as much as possible.
