Description

[Detailed description of the invention] This invention forms a break line for each unit length of use, such as a continuous plastic bag or toilet paper, and cuts the position of the break line to create a roll wrapped with a certain amount of band material to be used. Ba,
It relates to a cylindrical packaging container that is cut at the break line and stored in an easy-to-use state, and more specifically, it consists of a main body and a lid that are made by dividing a cylindrical body large enough to store a roll into two parts. A cylinder whose side edges are joined by a hinge, whose lid can be closed and the strip material can be pulled out from the gap between the other side edges, and whose edge is equipped with an element for cutting the strip material into unit lengths. The present invention relates to containers for packaging.

(Prior art and its problems, etc.) Conventionally, the above-mentioned cylindrical packaging container
It is described in Publication No. 73 and belongs to the publicly known.

However, this known cylindrical packaging container is provided with a cutting blade having a length spanning the entire width of the strip for cutting the strip.

Therefore, it is not intended for storing or cutting out and using a roll of strip material with a break line formed for each unit length.

That is, the present invention is characterized in that a wrap film, aluminum foil, etc., in which no break line or the like is formed on the strip material, can be cut with a cutting blade at a position of an arbitrary usable length to make it usable.

On the other hand, the cylindrical packaging container described in Japanese Utility Model Application Publication No. 54-52443 stores a roll of band material with a break line formed for each unit length used, and when it is pulled out, the container is placed in the center of the outlet. This configuration allows the protrusion cutter provided to break the break line and cut it out for use.

However, since the roll stored in the container is not equipped with a brake acting part and rotates freely according to the pulling force of the strip material, it is actually quite difficult to break the roll by hooking the break line with the protrusion cutter.

In other words, it is necessary to apply a reaction force at least enough to overcome the resistance when the protrusion cutter penetrates the break line, otherwise the break line will not be broken by the protrusion cutter and will pass through, resulting in the strip material being damaged. I can't use it because it gets withdrawn without limit.

In addition, since it does not have a brake acting part, it cannot prevent the rolls inside the container from reversing for some reason, and due to this reversal, the broken tip of the strip that was peeking into the strip material outlet of the container will be drawn into the container. Then, the next time I use it, I have to somehow remove the broken tip.
Very difficult to use.

In this regard, both the cylindrical packaging container described in Japanese Utility Model Publication No. 55-5473 and the roll holder described in Japanese Utility Model Publication No. 50-813 are configured to apply a brake to the strip material using the force of closing the lid. However, since the brake is applied uniformly over the entire width of the strip material, it is not suitable for pre-cutting by cutting the break line with a protrusion cutter.

This is because the action of cutting the break line of the strip material with a protrusion cutter means that the protrusion cutter pierces the abutment part (a part of the break line) weakened by the break line, and is pulled out. This is a phenomenon in which the trailing portion of a certain strip is held back at the break line, and as a result, the break at the break line gradually expands due to the pull-off force of the strip, eventually leading to complete breakage (cutting).

Therefore, it is meaningless to apply the brake uniformly over the entire width of the strip.

Rather, it is known that the best way to reliably cut the break line of the strip with a relatively small pulling force is to concentrate the brake generated with the same force at a point just in front of the protrusion cutter. Obtained.

(Purpose of the invention) Therefore, the purpose of this invention is to generate the brake of the band material generated based on the force of closing the lid so as to concentrate it at a point immediately in front of the protrusion cutter, thereby causing the breakage of the band material by the protrusion cutter. To provide a cylindrical storage container for strip material rolls which is improved in structure to make it easy and reliable to puncture and break the wires, thereby making effective the effect of the breaking lines of the stored strip material rolls.

(Structure of the invention) In order to achieve the above object, the cylindrical packaging container of this invention is provided with a cylindrical packaging container that has a cylindrical packaging container that has a cylindrical packaging container that has a cylindrical packaging container that has a cylindrical packaging container that has a cylindrical packaging container that has a cylindrical packaging container that has a cylindrical packaging container that has a cylindrical packaging container that has a cylindrical packaging container. , a brake acting part in the shape of a small large protrusion or a flat plate protrusion is provided.

A chevron is formed at a substantially central part in the width direction of the drawer side edge of the strip of the main body or lid, on the further side in the drawer direction of the strip than the brake acting section, and at a position close to the brake acting section. It is said that the structure is equipped with a protrusion cutter.

(Effect) In other words, the force of closing the lid presses the brake acting portion against the strip material, so that when the strip material is pulled out, a brake is applied to the strip material.

In particular, since the brake acting portion is in the form of a small large protrusion or a flat plate, the force for closing the lid is concentrated on the small brake acting portion, thereby generating a necessary and sufficient amount of brake on the strip material.

Moreover, since the brake acting part is provided at a position just before the protrusion cutter, the tension for pulling the strip material is concentrated between the brake action part and the protrusion cutter, and the protrusion cutter pierces the break line. Provides necessary and sufficient reaction force against the actual resistance.

Therefore, at the same time that the weak break line reaches the position of the protrusion cutter, the tip of the protrusion cutter pierces (pierces) the weak break line.

In other words, if the direction in which the strip material is pulled (the direction of the tensile force) is bent at a sufficiently large angle with respect to the direction in which the protrusion cutter projects, the protrusion cutter will of course have a strong effect of penetrating the break line, but the brake action section will Therefore, even if the strip material is taken in a state where the refraction angle is almost zero, the protrusion cutter can reliably break through the break line.

In addition, since the brake action part is located just in front of the protrusion cutter and the brake is concentrated in one point, the strip material can be pulled out without having to do the troublesome work of pulling it out by pinching both ends of its width with both hands. It is possible to break it even if it is not pulled forward in a straight line connecting the brake acting part and the protrusion cutter.

In other words, the strip material can be cut reliably even if the strip material is pinched at a suitable cylindrical point within the width of the strip material with one hand and, in some cases, pulled out at a certain angle diagonally to the straight line connecting the brake acting part and the protrusion cutter. Can be used.

In other words, there is considerable flexibility (degree of freedom) in the operation (handling) of cutting and using the strip material, and one-touch operation is possible.

Therefore, it can withstand rough use in busy shops and the like.

Furthermore, since the brake action section is working, the cut end of the strip is reliably held in a state where it partially protrudes from the drawer opening of the storage container.

Therefore, the next time you use it, all you have to do is pinch the cut end of the protruding strip and pull it out.

(Example) Next, this invention will be explained with reference to illustrated embodiments.

1 to 4 show a roll with a holder, which is a first embodiment of this invention.

In the figure, 1 is a roll of strip material 1', which has a perforation-like break line 2 with no complete cut for each unit used, and 3.
is a holder having a container structure that can be opened and closed and rotatably accommodates the roll 1.

In the case of this embodiment, the band material 1' is a so-called continuous plastic bag, and the heat seam line 4, which forms the bottom of the bag, is located slightly ahead of the break line 2, which connects the individual bags that are used as units. ... is formed parallel to break line 2....

The holder 3 has a main body 3b and a lid 3c, which are shaped like a long and narrow cylindrical container large enough to accommodate the roll 1 divided in half, and have a thin wall structure (however, this is not the case) at one side edge thereof.

), and when the lid body 3c is in the closed state (FIG. 4), the other side edge 3b't
3C' Width that allows the strip 1' to be pulled out without any problem between the opposing surfaces (as shown in Figures 1 and 2, the edge 3"t3
The width extends over the entire length of c' and is slightly larger than the width 1 of the strip 1'.

) (Fig. 3, B-C1, and Fig. 4).

The holder 3 has a claw 3d protruding from the side of the main body 3b, and a locking piece 3f having a hole 3e that engages with the claw 3d is attached to the lid 3c.
The lid member 3c is provided on the side of the lid body 3c, and by engaging them, the lid body 3c is kept in a closed state.

Next, in the figure, 6 is the central part in the width direction of the gap 5, and is a brake piece fixed to the edge 3b' of the main body 3b forming the gap 5, and 7 is the brake actuating part. At the same edge 3b', the strip 1' is lower than its brake piece 6.
This is a protruding cutter that is provided in the shape of an upwardly rising chevron at a position directly ahead in the passing direction (rightward direction in FIG. 4).

Note that the location where the protrusion cutter 7 is located is an extended portion 3b'' that extends the edge 3b' outward in the horizontal direction.

The brake piece 6 and the protrusion cutter 7 are separate from the holder 3, and are integrally made of soft rubber with a large coefficient as shown in FIG. 3A. 6' is tightly fitted and fixed in the direction of the arrow in a hollow space 8' in a correspondingly shaped concave notch 8 provided at a corresponding position on the edge 3b'.

Further, the brake piece 6 protrudes from the upper surface of the edge 3b' by a height corresponding to the gap 5 (approximately 1 mm), and the opposing edge 3b'
It is configured to locally abut against the facing surface of C', clamp the band material 1' between them, and apply a braking force to the withdrawal of the band material 1'.

In addition, even when the width 1 of the strip material 1' is approximately 20 cm, the integral body of the brake piece 6 and the protrusion cutter 7 has a width of approximately 177 cm.
It has a small configuration of about 1rIIL.

In addition, the brake action piece 6, the protrusion cutter 7, and the extension part 3b
"" may be a separate body from the main body 3b, and the three parts 6, 7.3b" may be integrated.

In FIG. 2, 9 is a semicircular groove shaped roll receiver formed in the main body 3b, and 10 is a viewing window formed in the lid 3C.

Next, the usage and operation of the roll with holder configured as described above will be explained.

For the first time or when the existing roll is used up, the lid 3
Open c as shown in Figure 2.

Then, a new roll 1 prepared separately is inserted and set on the roll receiver 9 of the main body 3b in such a manner that the strip material 1' is rewound diagonally upward from the bottom as shown in FIG. The lid body 3c is closed with the tip thereof pulled out at least from the gap 5, and the hole 3e of the locking piece 3f is engaged with the claw 3d to close the lid.

The holder 3 is fixed with screws or the like with the bottom of the main body 3b placed on the support base 11, as shown in FIG. 4, for example.

Thereafter, the tip of the strip 1' is pinched and pulled out, for example, in the direction (horizontal direction) indicated by the two-dot chain line.

In this case, when the strip 1' is pulled out, an appropriate braking force is generated by the brake pieces 6 that clamp the strip 1' and by the force that keeps the lid closed, and the braking force is , in the band 1', the tension acts intensively in the band clamping pressure width range due to the local brake pieces 6, and also in the band clamping pressure width where the concentrated tension is acting on the band 1'. The portion within the area is pressed against only the tip of the protruding cutter (the state shown by the one-dot chain line in Fig. 4), so when the break line 2 of the strip material 1' reaches the protrusion cutter 7, a chevron is formed on the weak break line 2. The tip of the protrusion cutter 7 will surely and easily pierce through.

Therefore, as the strip material 1' is continued to be pulled out, the protruding cutter 7 and the brake 6 that are stuck at the break line 2 act to prevent the strip material 1' from advancing, and the break at the break line 2 expands. Finally, I was able to cut out one piece of the bag for each unit of use.

Because of this, the magnitude of the braking force generated by the brake piece 6 does not need to be very large.

In addition to the manner of use of this roll with holder, as shown in FIG. 5A, in addition to the manner of use shown in FIG.
As shown in FIG.
It can be used in a mode in which the strip material 1' is pulled out in a substantially vertical upward direction, or in a mode in which the holder 3 is fixed to the ceiling 14 and the strip material 1' is drawn out in a substantially vertical downward direction as shown in FIG. 5C.

Next, FIG. 6 and subsequent figures show examples of different configurations of the holder as other embodiments of this invention.

First, FIGS. 6A and 6B show a configuration in which a brake piece 6 and a protrusion cutter 71 are integrally attached to an extended portion 3b'' of an edge 3b' of a main body 3b constituting the holder 3. However, the brake piece 61 forms a plane that is on the same level as the upper surface of the edge 3b', and on the other hand, the opposite side of the brake piece 61 at the edge 3c' of the lid body 3c is locally formed into a space equivalent to the gap 5. It is shown as a protruding part 15 having a height of 15, and is configured to clamp the band material 1' between the protruding part 15 and the brake piece 61.

Next, in FIG. 7A, a chevron-shaped protrusion cutter 7° is integrally formed on the extended portion 3b'' of the edge 3b' of the main body 3b constituting the holder 3, and on the other hand, the edge 3C' of the lid body 3c. A protrusion 62 for a braking action which protrudes in an arched shape is integrally formed, and this protrusion 62 and the edge 3 of the main body 3b facing it are integrally formed.
A configuration is shown in which the band material 1' is clamped between the belt member b' and the belt member b'.

Furthermore, FIGS. 7B-C are similar to those in FIG. 7A in that a chevron-shaped protrusion cutter 72 is integrally formed on the extended portion 3b'' of the edge 3b' of the main body 3b. On the other hand,
In FIG. 7B, as a separate item from the holder 3,
In addition, a brake piece 63 as a braking action part formed in a semi-cylindrical shape from a soft rubber with a large coefficient is attached (glued) onto the edge 3b' of the main body 3b.
In FIG. 7C, the same brake piece 63 as before is attached to the edge 3 of the lid body 3c.
The configuration installed on c' is shown.

FIG. 8 A-B-C shows the brake piece 64 and the protrusion cutter 7.
4 is separate from the holder 3 and integrally made of soft rubber with a large coefficient, and is provided on an extended portion 3b'' of the edge 2b' of the main body 3b constituting the holder 3. trunnion shafts 17, 17 on both sides.
This shows a configuration that is swingably mounted.

In this case, the height of the brake piece 64 from the trunnion shaft 17 is installed at the same level as the upper surface of the edge 3b' of the main body 3b (FIG. 8C), but the strip material 1' is When it is pulled out (FIG. 8B), it strongly hits the tip of the protruding cutter 7 and generates a moment about the trunnion shaft 17, causing the brake piece 64 to come into contact with the opposing edge 3c', while the strip material 1' It is characterized by its structure that generates braking force by squeezing.

In each of the above embodiments, the protrusion cutter 7 extends outwardly from the central portion of one of the edges of the other side that cuts through the gap between the holders, and is erected in the direction of the extended portion 3b''. In other words, the drawings of each embodiment show a structure in which the strip 1' projects upwardly with respect to the direction in which it passes through the gap 5.

In this case, if the strip material 1' is pulled out in a direction parallel to the gap 5 shaped surface on the other side edge, the pulling direction is a direction that can be easily and accurately visually recognized.
As a result, the user (worker) can always pull out the strip material 1' in a fixed direction, and if the angle, shape, dimensions, etc. of the protruding direction of the protrusion cutter are appropriately designed, it is possible to cut out each unit of use. It is always easy to pull out, the strip material 1' is not easily scratched by the protruding cutter, and it can be cut and used under conditions where it can be reliably broken.

In each of the above embodiments, if the extended portion 3b'' is secured, the folded portion of the edge 3b't 3c' that protrudes outward (horizontally outward in the figures of each embodiment) is The main body 3b and the lid body 3c are not necessarily required.
The other side of each edge of the main body portion may be used as edges 3b' and 3c'.

On the other hand, in FIGS. 9A and 9B, the protruding cutter 75 protrudes in a direction that extends the gap 5-shaped face on the other side edge outward, that is, in a direction in which the strip material 1' passes through the gap 5. A structure that protrudes in parallel horizontal directions is shown.

The protrusion cutter 7 is formed integrally with the brake piece 65,
It is attached to an extension 3b'' of the edge 3b' of the main body 3b.

In this configuration, the strip 1' is pulled out obliquely downward as shown in FIG. 9B.

In addition, in this embodiment, the edges 3b' and 30' do not necessarily require the folded part and the extended part 3b'' that project outward in the horizontal direction, and are simply formed by the main body 3b and the lid. The other side of each edge of the main body part of 3c is the edge 3b't 3c
' may also be used.

Next, FIGS. 10A and 10B show another embodiment of this invention, in which the brake action part is configured only as a part that locally contacts the strip material 1' and generates sliding resistance. The formula is shown below.

In other words, the edge 3c of the lid 3c that invades the gap 5 of the holder 3
Brake piece 6, which is separate from the holder 3 and is made of soft rubber with a large coefficient of friction, is placed in the center of the
6 is in a state in which it slightly protrudes from the surface of its edge 3c' but never contacts the edge 3b' of the facing main body 3b (
This is a configuration in which it is fixedly attached as shown in FIG. 10B).

Therefore, the strip 1' is pulled out horizontally (10th
When passing through the gap 5 (indicated by the two-dot chain line in Fig. The strong contact produces a moderate braking force, and the braking force is
, the tension acts intensively on the width of the band to be squeezed by the local brake pieces 66, and the portion within the width of the band 1' where the concentrated tension is applied is as follows: It is strongly pressed only to the tip of the protrusion cutter 76 (the first
When the weak break line 2 of the strip material 1' reaches the protrusion cutter 76, the tip of the protrusion cutter 76 will surely and easily pierce the break line 2. Ensures rupture.

The smaller the distance S from the brake piece 66 to the protrusion cutter 76, the closer the angle α becomes to an acute angle and the greater the slip resistance becomes, which is advantageous in use.

In the roll with holder of this embodiment, compared to the push-type brake acting section shown in each of the above embodiments, even if there is variation in the force for closing the lid 3c, or the force changes depending on the state of use. Even if such a situation occurs, it has the advantage of producing a constant slip resistance (braking force) regardless of such a situation.

Next, FIG. 11A-B shows the main body 3b constituting the holder 3.
And both ends 18 of the C-ring spring 18 are attached to the side wall portion of the lid body 3c.
a, 18b are symmetrical positions centered on the hinge joint 3a between the main body 3b and the lid 3c, and both ends 18a, 18b
This shows a configuration in which the lid is fixed with a spacer tag expanded by an appropriate initial deformation amount to maintain the lid in the closed state.

In the figure, 19 is a retaining wall for the C-ring spring 18, and 20 is a support rib for the retaining wall 19.

In the case of this holder 3, the distance X□ between both ends of the C-ring spring 18 is maximum at the vertical position y□ where the lid 3C is opened approximately 90 degrees, and the C-ring spring The distance between both ends 18a and 18b of 18 is smaller than X□.

That is, in the opening/closing operation of the lid body 3c, the y1 position becomes a so-called consideration point, and when the lid is closed, the C-ring spring 1
8 performs the function of maintaining the lid closed state (and thus presses the brake action section), and conversely performs the function of maintaining the lid closed state when the lid is open.

Next, FIG. 12A-B shows a lid body 3c constituting the holder 3.
An elastic locking piece 21 that is curved in a U shape and protrudes in the opening/closing direction of the lid body 3C is integrally formed on the side of the body 3b.
A substantially rectangular locking frame 22 into which the locking piece 21 enters as the lid 3c closes is integrally formed on the side thereof.

That is, the locking piece 21 has a locking claw 21a, and when the locking piece 21 enters the locking frame 22 to a predetermined depth, the locking claw 21a engages with the lower edge of the locking frame 22. Keep the lid closed.

In the figure, 23 is a dowel protruding from the side of the lid body 3C, and 24 is a dowel hole formed in the side of the main body 3b at a position corresponding to the dowel 23. The dowel 23 fits into the dowel hole 24. The main body 3b and the lid 3 in the closed state of the lid 3c
The positional relationship with c is restricted.

In each of the above embodiments, the protrusion cutter is installed on the main body 3b side, but the projection cutter is not limited to this, and may be installed on the lid body 3c side. Then, it may be installed on both the main body 3b and the lid 3c, and both are included in this invention.
