[For production]

According to the above configuration of the present invention, the container filled with the paste-like article is housed in a cylindrical body with both ends open or in the cylindrical part of the extruder, and is elongated by the action of the piston that is pushed forward by a predetermined amount by the extruder. It is crushed by a predetermined amount in the horizontal direction. By this crushing, the paste-like article in the container is extruded from the extrusion port by a predetermined amount. Since the container is housed in the cylindrical body or the cylindrical part of the extruder, it will not break laterally during this crushing process and will be reliably crushed in the length direction.

〔Example〕

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows an example of a container for a pasty article used in the present invention. The container 1 is formed into a cylindrical shape with a blow bottom made of a suitable resin material, one end is closed, and the other end is provided with an extrusion port 2. The extrusion port 2 is formed with an opening 2a having an appropriate shape. A cap 3 is attached to the extrusion port 2 by, for example, threaded engagement. Instead of the cap 3, a sheet material such as aluminum foil may be attached by heat sealing or the like to seal the opening 2a.

When the container 1 is used for foods such as mayonnaise, the container 1 is constructed to have barrier properties against moisture. Since the container 1 has a thin wall, it can be crushed in the length direction until almost no internal volume is left.

Resin containers conventionally used for mayonnaise and the like can be crushed laterally, but because the walls have relatively high rigidity, they cannot be crushed longitudinally without buckling laterally. Can not. The container 1 of the present invention has a sufficiently thin wall thickness so that it can be crushed in the longitudinal direction by pushing in the longitudinal direction from one end.

FIG. 2 shows another type of container.

This container 4 is constructed by stacking resin films and heat-sealing the peripheral portions, and has an extrusion port 5 at one end in the length direction. This container 4 also has extremely low rigidity, so it can be crushed in the length direction until almost no internal volume is left.

FIG. 3 shows a cylindrical body and a piston used in the present invention. The cylindrical body 6 is a molded product made of a resin material, and is formed into a relatively rigid cylindrical shape. An annular flange 8 having an open lower part is formed at one end of the cylindrical body 6. The other end 9 of the cylindrical body 6 is left open. The piston lO is loosely fitted into the cylindrical body 6, and the cylindrical body 6

The main body 913 has end plates 14 and 15 provided at both ends thereof. The end plate 14 has a cylindrical portion 14a and an annular flange portion 14b.
The cylindrical portion 14a is coupled to one end of the main body portion 13. The annular 7 flange portion 14b has an opening 1 due to its inner periphery.
Form 4d. The end plate 15 includes a disk 815 a and a peripheral cylindrical portion 15 b, and the cylindrical portion 15 b is coupled to the other end of the main body portion 13 .

A push rod 16 is placed through the disc portion 15a of the end plate 15. A disk-shaped push plate 16a with a small radius is attached to the end of the push rod 16 located within the housing 912.

A fixed handle 17 is attached to the disk B 15 a of the end plate 15 on the outside of the housing 12 . Further, a movable handle 18 is attached to the fixed handle 17. The movable handle 18 has a pawl (not shown) that engages with a tooth groove formed on the outer surface of the push rod 16, and each time the movable handle 18 is operated, the push rod 16 is moved a predetermined amount.
In FIG. 4, it can be advanced to the left. Since this configuration of the extruder 11 is well known, further detailed explanation will be omitted.

The cylindrical body 6 has a diameter that just fits into the housing fB12 of the extruder 11. When using, please refer to Figure 1 or 2.
In a state where the container L4 shown in the figure is filled with a paste-like article,

The extrusion port 2.5 is arranged so as to protrude from the opening 14d of the end plate 14 of the extruder 11.

When the movable handle 18 is operated with the push plate 16a at the tip of the push rod 16 engaged with the piston 10, the push rod 16 is advanced by a predetermined amount, and the piston 10 is pushed forward by a predetermined amount within the cylindrical body 6. .

At this time, since the container 1.4 is restrained by the cylindrical body 6, it is crushed in the length direction without buckling in the lateral direction. As a result, the paste-like article in the container is pushed out by a predetermined amount. By repeatedly manipulating the movable handle 18, the container 1.4 can be collapsed longitudinally until it has almost no internal volume, and the paste-like article inside is almost completely expelled. The used container is discarded and a new container filled with the pasty product is used in the same manner.

In the embodiment described above, the piston lO is the push rod 1
Although the push plate 16a is provided separately from the piston 6, by making the diameter of the push plate 16a sufficiently large, the push plate 16a can be used as a piston. In this case, the floating piston lO is not required.

FIG. 5 shows another embodiment of the extruder used in the present invention. The extruder 21 is the extruder 11 of the previous embodiment.
The main body part 23 has a semicircular cross section like the main body part 13 in , and end plates 24.25 having the same configuration as the end plates 14.15 are attached to both ends of the main body part 23.

A fixing metal fitting 31 is provided on the other edge.

In the extruder 21 of this embodiment, the container 1.4 filled with the paste-like article is stored as it is in the storage section 22 through the loading opening formed when the lid 29 is opened. Then, by closing the lid 29 and operating the handle 28, the container 1.4 can be crushed in the length direction.

FIG. 6 shows still another embodiment of the extruder used in the present invention. Extruder 41 of this embodiment
has a cylindrical main body 42, and an end plate 43 is attached to one end of the main body 42. The structure and arrangement of the push rod 44, fixed handle 45, and movable handle 46 are the same as in the previous embodiment. At the tip of the push rod 44 is a piston (not shown) similar to the piston 26a of the previous embodiment. is provided.

A ring-shaped lid 47 is attached to the tip of the cylindrical main body 42 by a hinge 48 so as to be openable and closable.

The lid 47 has an opening 47a in the center. Furthermore, the lid 47
can be fixed to the main body part 42 in a closed state using a fixing fitting 49. In this embodiment, the container 1.4 filled with the pasty article can be inserted from the tip of the cylindrical body 42 with the lid 47 in the open position. Thereafter, the lid 47 is closed and the same operation as in the previous embodiment is performed.

FIG. 7 shows another embodiment of the extruder according to the present invention.

The extruder 51 has a main body 52, one end of the main body 52, and a screw 52.
The container 54 has a cylindrical body 55 and an accommodating portion 54 consisting of a lid 53 that is engaged with each other at c, and a container 56 loaded with a paste-like article A is inserted into the cylindrical body 55. A piston 57 comes into contact with the bottom of the container 56, and a push rod 58 pushes the piston 57 forward, crushing the container 56 and extruding the paste-like article A from the extrusion port 56a. Although not shown, the structure and arrangement of the fixed handle and the movable handle are similar to those in the previous embodiment. An opening 59 is formed in the center of the lid 53 constituting the storage section 54, and the container 5 is opened from the opening 59.
No. 6 extrusion port 56a protrudes. In addition, the main body 52
In addition to the screw 52c, a screw 52d is formed at the other end, and an operating section consisting of a fixed handle and a movable handle is connected to this screw 52d.

Enlarged diameter portions 55a and 55b are formed on the outer periphery of the cylindrical body 55, and the enlarged diameter portion 55a is formed at a certain distance from one end of the cylindrical body 55. An annular portion 52a is formed on the inner periphery of the main body 52 at an end thereof which contacts the enlarged diameter portion 55a, and an annular portion 52b is formed at the other end of the main body 52. is trying not to fall. With this configuration, the cylindrical body 55 can slide within the main body 52 by a distance X in the axial direction of the cylindrical body 55.

Note that the main body 52 is a two-piece product, and after the cylindrical body 55 is placed inside the main body 52, the main body 52, which is a two-part product, is
join.

A cylindrical hollow portion 60 having a diameter larger than the outer diameter of the piston 57 is formed concentrically with the axis of the piston 57 inside the lid 53 which is threadedly engaged with the main body 52 .

When the piston 57 is pushed forward to push out the paste-like article from the extrusion port 56a, if the operation is stopped while the piston 57 is pressed and the container 56 is crushed, the paste-like article A is extruded by the desired amount from the extrusion port 56a.
may not cut as much as desired and may continue to leak in small amounts due to its viscosity. In order to prevent this small amount of leakage, if the piston 57 advances a predetermined distance and crushes the container 56, then it retreats a short distance, and the crushed container 56 increases its internal volume by the amount of the retreat. As a result, the paste-like article A extruded from the extrusion port 56a is sucked back into the container 56, thereby preventing a small amount of leakage. Therefore, the operating section of the pusher is configured so that the piston 57 moves back a short distance after moving forward a predetermined distance, and further,
Since the container 56 and the cylindrical body 55 are engaged by frictional force and can only move as one unit, if the cylindrical body 55 is formed to be slidable inside the main body 52, the cylinder will move as the piston 57 moves forward and backward. The shaped body 55 and the container 56 also move forward and backward, so that a desired amount of the paste-like article A can be reliably pushed out, and a small amount of leakage can be prevented.

When the container 56 is completely crushed and reaches almost the end of the lid 53, the bottom of the crushed container 56 touches the piston 57.
The piston 57 may become stuck between the inner peripheral surface of the cylindrical body 55 and the inner peripheral surface of the cylindrical body 55 and become unable to move back. In this case, if the cylindrical hollow part 60 is provided as in this embodiment, even if the container 56 is crushed to the end of the lid 53, the bottom of the container 56 will be open to the cylindrical hollow part 60, and the piston 57 and the inner circumferential surface of the cylindrical body 55.

Note that the enlarged diameter portions 55a and 55b are at least the enlarged diameter portion 5.
5a is sufficient for the cylindrical body 55 to slide. Providing the enlarged diameter portion 55b in addition to the enlarged diameter B55a allows the cylindrical body 55 to be maintained at a substantially concentric position with the main body 52 inside the main body 52, which is preferable for the forward and backward movement of the piston 57.

Further, as shown in FIG. 8(a), a pair of notches 61a and 61b are formed at both diametrical ends of the enlarged diameter portions 55a and 55b formed on the outer periphery of the cylindrical body 55, and a pair of notches 61a and 61b are formed on the inner periphery of the main body As shown in FIG. 8 et al., a pair of protrusions 62a1B2b may be formed at both ends in the diametrical direction to a size that allows them to pass through the notches 51a and 61b. If the enlarged diameter portions 55a, 55b and the main body 52 are formed in this way,
After inserting the cylindrical body 55 into the main body 52 by aligning the notches 6ta and 61b with the protrusions 62a and 62b, the cylindrical body 55
By slightly rotating the cylindrical body 55, the cylindrical body 55 will not fall out from the main body 52. When necessary, the cylindrical body 55 can be removed from the main body 52.

〔Effect of the invention〕

As described above, in the present invention, a longitudinally collapsible container filled with a paste-like article is housed in a cylindrical body or a cylindrical housing part to restrain lateral buckling. However, the container is crushed in the length direction by a pusher to push out the items inside the container, and the container can be thrown away after use. Therefore, it is convenient to use, and when used for food, it is possible to avoid the problem of unsanitary refilling, which is the case with conventional dispensers.
