Abstract

PROBLEM TO BE SOLVED: To provide a sealing-up tool which can be easily attached to the pouring opening of a paper pack and can easily and tightly reseal it after the pack has been unsealed and the pack can be kept even in a fallen state by providing a folded part where mutual ends of a tightening bar are connected so as to be freely foldable and providing a hooking claw and a claw receive at the other end of the tightening bar respectively and further, providing a fastening force-adjusting element in one tightening bar. SOLUTION: The bent 12 of tightening bars 1 can be freely folded and it has a necessary strength. The mutual insides of the tightening bars 1 are connected by a thin platelike material and the mutual outsides are connected by a thin platelike material through a platelike material. The hooking claw 2 connects the opened ends of two tightening bars 1 or separates them from each other and the trigonal part is fitted to a claw receive 3 for thier connection. A paper pack 9 is hard and hardly fit to the bar if only the hard tightening bar 1 is used and a gap is hard to set and hence, the uneven gap is adjusted as a cushion or a tightening force is reduced by a fastening force-adjusing element 13. The element 13 is provided with an adjusting piece 131 that a thin platelike material is obliquely attached and the paper pack can be easily bitten by a biting blade 132 by reducing a pressure-receive area.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sealing device for sealing a spout of a roof paper pack (hereinafter abbreviated as a paper pack) after opening the spout.

[0002]

2. Description of the Related Art Conventionally, as a sealer for a spout portion of an opened paper pack, Japanese Patent Application Laid-Open No. 8-58825, "Paper Pack Cap for Mouth" discloses a plug that can be attached to the spout portion of a paper pack. It is composed of a U-shaped fitting member having a mouth, and a U-shaped sliding member having a rail-shaped projection provided on both sides of the inner wall with a sliding groove of the fitting member. In addition, a mouth cap in which the fitting member and the sliding member are slidably inserted is described.

Although not for paper packs, Japanese Patent Application Laid-Open No. 9-4611 "Clip" discloses a method for sealing an opening of a plastic film bag or a part of a tube by using a clip made of a hard material. A clip provided with an elastic member is described. In addition, for general bags, various types of sealers using a combination of a convex fastening rod and a concave fastening rod having a U-shaped cross section are used.

[0004]

SUMMARY OF THE INVENTION The mouth cap described in Japanese Patent Application Laid-Open No. 8-58825 is difficult to attach to the spout of a paper pack. The reason is that the gap between the U-shaped fitting members is substantially the same as the paper thickness of the spout portion of the paper pack, there is no guide or inclination at the entrance of the gap, and furthermore, the fitting member Since the sliding member fits perfectly on the outside of the paper box, the gap cannot be widened, and the gap between the opposed rail-shaped projections provided on the sliding member is the spout of the paper pack container. This is because the sheet thickness is set slightly narrower than the sheet thickness of the sheet, so that the sheet is pressed down. Further, since the inside of the fitting member is not provided with a slip stopper, when there is no holding piece, the mouth cap is easily detached from the spout portion both upward and laterally.

In the clip disclosed in Japanese Patent Application Laid-Open No. 9-4611, an elastic member made of a different material is provided inside an arm made of a hard material. There are various technical difficulties, which are explained in detail in the specification. Special molding machines are required, molding conditions are complicated, molding time is long, and material and processing costs are both high.

[0006] The most frequently used paper packs are those having a capacity of 1000 ml. Normally, when opened, they are tall when opened, so that they are stored standing upright in the door pocket of a refrigerator. However, the space in the door pocket is limited, and various types of paper packs such as milk and juice are used especially in the summer season, so it has been difficult to secure a storage space.

[0007] The paper pack before being opened is stored in an empty space of a refrigerator in a state of lying down. The opened paper pack can also be stored sideways if the spout can be sealed, so that it can be stored easily even if there is not enough room in the refrigerator door pocket.

An object of the present invention is to provide a paper pack for a paper pack which can be easily attached to the spout of a paper pack and can be easily sealed so that the spout can be stored sideways after being opened. It is to provide a sealer.

[0009]

In order to solve the above-mentioned problems, the sealed device of the present invention is to fold the opened spout portion 92 and press down on the spout portion. There are two types, one in which the sealer can be attached to the crimping section 91 with the 92 open and the other in which the sealer cannot be attached.

There are four ways to press the folded spout 92, namely, to clamp the side from the left and right by turning it half a turn from above and to slide it from the horizontal direction and to clip it from above into a clip shape to tighten.

[0011] In order to facilitate mounting, the fastening rod 1 must be V-shaped.
Open in the shape of a letter. Guide or tilt the insertion slot. A tightening force adjusting element 13 is provided or an auxiliary rod is provided so that a strong force is not required for tightening (mounting). We take measures such as. In order to seal the spout 92, the spout 92 must be sealed.
Is folded and measures are taken to hold it on top of it.

According to the first aspect of the present invention, the opened spout portion 92 is folded, the upper portion thereof is tightened and sealed, so that one ends of the two tightening rods 1 can be freely bent. To form a bent portion 12, a hook 2 and a hook receiver 3 are provided at the other end of the tightening rod 1, and a tightening force adjusting element 13 is provided on at least one tightening rod 1. Further, a sealer for a roof paper pack.

Although the shape of the tightening rod 1 may be a rectangular parallelepiped,
For the purpose of weight reduction, material saving, shortening of molding time, and the like, a cross section may be provided with a reinforcing rib like a U-shape or a Y-shape. Since the bent portion 12 may be freely bent and have a necessary strength, the insides of the tightening rods 1 may be connected to each other with a thin plate-like member, or the outsides of the tightening rods 1 may be connected to each other. May be combined with a thin plate through a plate.

The hooking claw 2 connects and separates the open ends of the two tightening rods 1 and has an arrow shape, and the triangular portion moves slightly due to the elasticity of the plate-like portion. The triangular portion is hooked and connected to the claw receiver 3. Other forms may serve this purpose. Since the hook receiver 3 is for receiving the hook 2, it may be the tightening rod 1 itself, but it is harder to come off when the hook is slightly inclined.

The tightening force adjusting element 13 is difficult to set the gap because the paper pack 9 is hard and does not fit easily with the hard tightening rod 1 alone. Therefore, the gap (thickness of the paper pack 9) is used as a cushion (absorbent). This is for adjusting the difference between the above and reducing the force required for tightening.

The tightening force adjusting element 13 has a thin plate-shaped end portion of the tightening rod 1 and has elasticity.
U-shaped, utilizing the elasticity of a thin plate-like part, attached to the inside of the tightening rod 1, and a thin plate-like oblique adjustment piece 131 and a food that reduces the pressure receiving area and facilitates biting There is a cutting blade 132. The tightening force adjusting element 13 may be attached to either of the tightening rods 1. Of course, both may be attached.

In general, various types of sealers for bags are used, but most of them are formed by engaging a convex fastening rod having a U-shaped cross section with a concave fastening rod having a U-shaped cross section. Is thin, flexible and easy to fit, so it is sandwiched between them and sealed. Due to the elasticity of the tightening rod, a gap between the convex shape and the concave shape is somewhat widened, and bags are sandwiched and sealed here.

In the convex shape and the concave shape, a 字 (pie)
There was a type, but all expanded and contracted in the horizontal direction, and none expanded and contracted in the vertical direction to act as a cushion. Also, none of them worked as bite blades. Some of the fastening rods did not bend. None of the bends (joints) had elasticity.

Since the paper pack 9 is hard and difficult to conform, it is difficult to set a gap between the tightening rods 1. If the gap is small, it will leak. If the gap is small, the hook 2 will not be hooked on the hook receiver 3. Even with a very small width, a strong force is required to hook the hook 2. If it is very slightly loose, it may leak after a long period of time, even if it appears to be sealed. It doesn't leak, but it leaks out like a jiwa. If there is a gap even at one location, there is leakage.
Therefore, in order to completely press the hard and unfamiliar spout 92, a strong force is required.

If a strong force is required for sealing, it is difficult for the female and child or the elderly to hook the hook 2.
Originally, it is hard to enter because it is pressed with your fingertips. However, when the tightening force adjusting element 13 is provided, the adjusting function works and the force is applied evenly. Therefore, even if the force is not so strong, the pressing can be uniformly performed and the sealing can be performed. Hold down the two hard and unfamiliar sheets (though four in the case of the spout 92) and completely crush the gap with a weak force,
It is important to provide a cushion to prevent leakage.

The adjusting piece 131 is a thin and elongated plate-shaped member, which is obliquely attached, acts like a spring due to the elasticity of the material, adjusts the gap, and absorbs a slight difference in thickness. The clip disclosed in Japanese Patent Application Laid-Open No. 9-4611 has an elastic member made of another material provided inside an arm made of a hard material, and aims at the same function, but is expensive as described above.

Elastic bodies such as rubber and thermoplastic elastomers are considered to be unsuitable for completely crushing the gaps between the hard and unfamiliar sheets. That is, a commercially available rubber band (also referred to as a rubber band; candy rubber) having a thickness of 1 mm and a width of 5 mm is interposed between the tightening rods 1 having an interval larger than the thickness of the spout 92, and the intervals are slightly changed. In the test, it was found that even when the hook 2 was barely hooked, leakage occurred, or the hook 2 was not hooked, and the distance could not be adjusted properly with the force of pressing with a finger. I tried to put the two rubber bands together, but it did not work. The rubber of the rubber band is softer as rubber.

Since the volume of the rubber remains unchanged even when it is compressed, it is considered that the rubber is hardly expected to function as an elastic body under such a force as to be pressed by a fingertip such as a sealer. When the pressure receiving area such as a point or a line has a small pressure receiving area, the force penetrates to absorb the force. However, when the pressure receiving area is large, the shape does not change with a weak force, and the cushion does not work.

Since the tightening force adjusting element 13 is made by integral molding of plastic, it can be manufactured at low cost. Also, the adjusting piece 131
Has the advantage that the action of the spring can be freely adjusted by the thickness, protrusion (width), shape (angle of V-shape, straight or curved, etc.), inclination, number, and the like. Since the biting blade 132 has a small pressure receiving area, the biting blade 132 can bite with a small force, and is sealed when the entire length of the spout 92 is pressed even with one linear shape.

The opposite tightening rod 1 against which the bite blade 132 hits
It is more effective if the blade receiving recess 133 is provided inside the. The number of the biting blades 132 may be one, but two are better because the same state will be obtained even if the direction is changed.
The bite blade 132 not only improves sealing performance but also prevents slippage.

The end of the tightening rod 1 is made thinner or the bent portion 12
The U-shape has a simple structure, the spring can be easily adjusted by the thickness, and the material is saved.

As described above, since the paper pack 9 is hard and has poor adaptability, simply adjusting the size of a conventional sealer for a general bag to the paper pack 9 does not work. At first glance they look very similar, so they can be thought of as similar, but essentially different. the material is,
Any hard material such as plastic or metal may be used, but it is preferable to use a hard plastic from the viewpoint of workability, economy and the like.

According to the second aspect of the present invention, the sealing device is connected to the crimping portion 9.
1, a mounting portion 4 for mounting the mounting portion 1 and two tightening rods 1 for tightening the folded spout portion 92 are connected to bendable by a bending groove 14. At least one of the two tightening rods 1 is provided with a tightening force adjusting element 13, one end is provided with a hooking claw 2, and the other end is provided with a claw receiver 3.

The mounting portion 4 is mounted on the crimping portion 91 of the paper pack 9, and is roughly divided into a portion to be tightened from the left and right, a portion to have a U-shaped cross section to cover from above, and one end joined in a hinge shape. There are three types, one in which the two plate-like objects are covered from above and sandwiched, and are stopped by hooking claws.

Some of these are sandwiched by the elasticity of the material, and others are sandwiched by hooking claws. The surface in contact with the crimping portion 91 may conform to the cross-sectional shape of the crimping portion 91, or may be provided with a projection or the like.

According to a third aspect of the present invention, the mounting portion 4 and the holding portion 51 for holding the folded spout portion 92 while rotating it from above are sandwiched by a connecting portion 52 so as to be semi-rotatable. is there.

The sandwiching portion 51 sandwiches the folded spout portion 92 by covering it from above, and has a U-shaped cross section and a hinge at one end (connecting with a thin plate-like material and bending). There is one in which two plate-like objects joined in a shape are covered from above, and are caught by hooking claws. The connecting portion 52 is connected semi-rotatably, and includes a combination of a projection and a concave portion or a combination of a projection and a hole, or a hinge shape.

According to a fourth aspect of the present invention, a slide piece 8 is slidably fitted outside the compression piece 7. Compression piece 7
Is located on the inner side of the slide piece 8 and is in direct contact with the crimping portion 91. The thin plate-shaped member is bent into an elongated U-shape,
The hook claw 2 and the claw receiver 3 are provided at the tip, and a bent groove 71 is provided in the middle.

Inside the compression piece 7, a tightening force adjusting element 13 is provided.
Is provided. Since the claw 2 and the claw receiver 3 are provided at the distal end of the compression piece 7, the gap is constant, and it is necessary to absorb the thickness variation of the spout 92. Tightening force adjusting element 13
May be provided on one of the compression pieces 7.

The slide piece 8 is formed by bending a thick plate into an elongated U-shape, and is slidably fitted to the outside of the compression piece 7. Is to tighten.

According to a fifth aspect of the present invention, a thick plate-like object is bent into a slender U-shape having an interval slightly smaller than the thickness of the crimping portion 91 to form a slide piece 8, and a guide is provided at the opened end. 41, and a holding piece 45 is provided below the U-shaped connecting portion.

The distance between the two slide pieces 8 is
Slightly smaller than the thickness of. Since the guide 41 is provided, the guide may be at a position where the leading end is reached. When the crimping part 91 is inserted, it is spread,
In close contact. The force with which the slide pieces 8 press each other is determined by a trial and error method based on the material and thickness of the slide piece 8, the shape and thickness of the connecting portion, and the like. The inserted crimping portion 91 can slide,
The contents are prevented from leaking from the spout 92. The force for pinching the folded spout 92 depends on the elasticity of the material.

The guide 41 is for facilitating the insertion of the crimping portion 91. The holding piece 45 is inserted below the crimping portion 91 to prevent the sealing device from coming off. The cross-sectional shape of the slide piece 8 is not limited to a rectangle and may be another shape. Since there is no hook 2, the opened tip moves slightly due to the elasticity of the material, so that the spout 92 can absorb thickness variations without the tightening force adjusting element 13.

According to a sixth aspect of the present invention, a plate-shaped auxiliary piece 5 is provided at the open end of the holding portion 51 having a U-shaped cross section.
5 is bendably connected to form a sealer. The sandwiching portion 51 is for sandwiching and sealing the folded spout portion 92, and the auxiliary piece 55 is used as a lever to expand the U-shape and cover the spout portion 92. The pinching force depends on the elasticity of the material. The corner on the connecting portion side of the sandwiching portion 51 becomes a fulcrum of the lever.

The interval between the U-shaped parallel portions of the sectional shape is
Although it may be slightly narrower than the thickness of the crimping portion 91, the tip portion is
Since they are spread by the auxiliary pieces 55, they may touch each other. The force for pinching the spout 92 depends on the thickness of the parallel portion, the shape and thickness of the connecting portion, and the like, but the pinch 92 is sufficiently pinched so as to prevent the contents from leaking.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on Examples.
This will be described with reference to the drawings.

Embodiment 1 Embodiment 1 will be described with reference to FIG. (A) is a perspective view showing the whole of the sealing device of the first embodiment, (B1) is a cross-sectional view taken along line AA, (B2) and (B3) are cross-sectional views taken along line AA of another example,
(C1) is a perspective view showing a state in which a sealing device is attached to the spout 92 of the paper pack 9, and (C2) is a crimping section 9 of the paper pack 9.
FIG. 1C is a perspective view showing a state where the spout 92 of the paper pack 9 is opened.

A hook claw 2 and a claw receiver 3 are respectively provided at the other ends of two substantially rectangular parallelepiped tightening rods 1 whose one ends are bendably connected by bending portions 12. The tightening force adjusting element 13 is provided on opposite surfaces. The tightening force adjusting element 13 includes an adjusting piece 131 and a biting blade 132. The length of the tightening rod 1 is substantially equal to the length of the upper crimping portion 91 of the paper pack 9. (The crimping portion 91 is
Refers to the entire crimped portion of the upper part of the paper pack 9 including )

As shown in (C1), the opened spout 92 of the paper pack 9 is folded, and a sealing device is attached to the entire crimping section 91 including the spout 92 and tightened. That is, the hook 2 is detached from the hook receiver 3, the two tightening rods 1 are opened in a V-shape, the crimping portion 91 is sandwiched and pressed, and the hook 2 is hooked on the hook receiver 3. When opening, hook claw 2
, Pull it outwards and it will come off easily, so remove the sealer.

As shown in (B3), a shallow groove-shaped blade receiving recess 133 is formed in a portion of the tightening rod 1 opposite to the tightening rod 1 provided with the bite blade 132, where the bite blade 132 contacts. It may be provided. Since the folded spout 92 is hard, if there is a recess,
The spout 92 pressed by the biting blade 132 sinks a little, but is pushed back due to the elasticity of the spout 92, so that the spout 92 adheres and is sealed. The force for tightening the tightening rod 1 may be smaller than the case where the bite blade 132 alone bites.

This sealing device can be easily attached and detached, and has an effect that the spout 92 can be sealed. Since it can be integrally molded with plastic, it can be inexpensive.

Embodiment 2 Embodiment 2 will be described with reference to FIG. (D) is Example 2
(E) is a perspective view showing another example, (F1) is a plan view showing another example, and (F2) is a plan view showing another example.

The second embodiment is obtained by adding another tightening force adjusting element 13 to the sealing device of the first embodiment. The tightening force adjusting element 13 shown in (D) has a thin plate shape at the open ends of the two tightening rods 1 so as to have elasticity.

The tightening force adjusting element 13 of (E) is formed by making both ends of one of the tightening rods 1 into a thin plate shape to have elasticity. Either of the clamping rods 1 may be provided with the clamping force adjusting element 13.

The tightening force adjusting element 13 of (F1) has a thin plate at the open ends of the two tightening rods 1 to give elasticity, and furthermore, makes the bent portion 12 U-shaped. Change to a thin plate shape,
The flat plate portion is a tightening force adjusting element 13 and the curved surface portion is a bent portion 12.

As shown in (F2), the tightening force adjusting element 1
3 may be provided on only one of the fastening rods 1. That is, only one of the tightening force adjusting elements 13 at the distal end may be provided, or the U-shaped portion may be provided only at either one.
That is, it may be J-shaped. Alternatively, the fastening force adjusting element 13 and the J-shape at the distal end may be provided on separate fastening rods 1 instead of being provided on one fastening rod 1 as in (F2).

The hook 2 and the hook 3 may be deformed as shown in (F2). That is, the hook 2 has a V-shaped concave portion, and the support of the hook 2 is extended to form a hook lever 26. The nail receiver 3 has a triangular convex portion.

In this way, after the two tightening rods 1 are brought close to each other, the hooking claws 2 are used to move the hooking claws 2 by the pawl levers 3.
When pressed against the convex portion of the hook, the catching claw 2 climbs up the triangular slope with a weak force according to the principle of leverage, and fits into the convex portion of the claw receiver 3. When the hook is to be removed, if the hook lever 26 is pulled outward, the hook 2 can be easily lifted off the triangular slope with a weak force. That is, even a weak person such as a female child or an elderly person can easily use it.

The force required to attach and detach the hook 2 and the hook 3 is as follows:
It can be adjusted by the length of the claw lever 26 and the angle of inclination of the triangular shape of the claw receiver 3. Note that the claw lever 26 has a width when the paper pack 9 is attached to the paper pack 9, so that the claw lever 26 does not become an obstacle and does not need to be too long.

When a force is exerted so that the clamping rods 1 are separated from each other, the triangular convex portion of the claw receiver 3 fits into the concave portion of the catching claw 2, so that unless the claw lever 26 is pulled outward, the hooking claw 2
And the nail receiver 3 do not come off.

When the tightening rod 1 itself is provided with a tightening force adjusting function as described above, the crimping portion 91 and the spout 92 can be formed without providing the tightening force adjusting element 13 inside the tightening rod 1. Can respond to thickness fluctuations. Of course, the tightening force adjusting element 13 may be provided inside the tightening rod 1 as shown in FIG.

Others are the same as in the first embodiment. This sealer has the effect of requiring less material in addition to the effect of the first embodiment. The use of the claw lever 26 has the effect that the sealer can be attached and detached with a small force.

Third Embodiment A third embodiment will be described with reference to FIG. (G) is Example 3.
(H) is a perspective view showing another example. In the third embodiment, the tightening rod 1 of the first embodiment can be extended, and the crimping portion 91 can be tightened with a strong force according to the principle of leverage.

An auxiliary rod 15 is connected to the distal end of the tightening rod 1 having the hooking claw 2 and the claw receiver 3 via a bending groove 14 so as to be bent outward. (The outside is connected and becomes the center of rotation.) When the auxiliary rod 15 is turned inward, the tightening rod 1 is in an extended form. Even if the auxiliary rod 15 is pressed inward to the maximum, it becomes only linear. Extended auxiliary rod 1
When the tip of 5 is tightened inward, a strong force is generated according to the principle of leverage, so that it can be easily used by girls and children and the elderly. The length of the auxiliary rod 15 may be the same as the length of the tightening rod 1 as shown in (G), or may be shorter than the length of the tightening rod 1 as shown in (H).

The widths (upper and lower) of the hooking claws 2 and the claw receivers 3 are narrowed so that the end surfaces of the auxiliary rods 15 are pressed against the upper and lower end surfaces of the tightening rod 1. The auxiliary rod 15 is a tightening rod 1
It may be used while being temporarily fixed to the outside. Since it can be tightened with a strong force, the inner tightening force adjusting element 1
3 may not be required.

Others are the same as in the first embodiment. This sealer has the effect that even a weak person can use it easily.

Fourth Embodiment A fourth embodiment will be described with reference to FIG. (I) is a perspective view showing the whole of the sealer of the fourth embodiment, (J) is a perspective view showing a method of use, (K) is a sectional view showing the crimping portion 91 of the paper pack 9, and (L) is B. FIG. 13 is a cross-sectional view taken along a line B-B, and FIG. (The tightening force adjusting element 13 is omitted in the drawings.)

The sealer of the fourth embodiment has a bent groove 14 provided near the bent portion 12 from the center of the tightening rod 1. The bent groove 14 has an opening inside, and the outside is thinly connected to a hinge-like (bendable state).

Since the fastening rod 1 can be bent outward around the bent groove 14 as shown in FIG. 3J, after being fully bent, the distal end portion with the hook 2 is removed. When pressed inward so as to pinch, the tightening rod 1 (mounting portion 4) of the bent groove 14 opens outward by leverage. Here, the opposite side of the spout portion 92 of the crimping portion 91 of the paper pack 9 is sandwiched. The bent portion 12 is hard, elastic, and has a holding force.

In this way, the sealer is mounted on the upper part of the paper pack 9. When pouring milk or other contents from the spout 92, use with the hooks 2 etc. removed.
When storing the paper pack 9 in the refrigerator, the spout 92 is folded and pressed so as to be sandwiched by the fastening rod 1, and the hook 2 is hooked on the hook receiver 3. Sealer is crimping part 9 at mounting part 4
Since it is attached to the first, it can be easily tightened.

The crimping portion 91 on the upper part of the paper pack 9 has a step as shown in FIG. Dimensions in mm, 1000

The sectional shape of the tightening rod 1 is as shown in FIG.
A U-shape, such as a U-shape or (N), may be used. The cost can be reduced by reducing the weight and the molding time, and if the non-planar surface is on the inside, the contact area is small, so that it functions as the biting blade 132. The tip may be pointed or an adjustment piece 131 may be attached to the tip. Others are the same as in the first embodiment.

This sealer is easy to operate and can be sealed, and can be used while attached to the paper pack 9 (the spout 9).
It is not necessary to remove the sealer when opening 2 and attach it each time it is stored in the refrigerator). .

(The tightening force adjusting element 13 is omitted in the drawing.) The sealing device according to the fifth embodiment also includes the crimping portion 91 of the paper pack 9.
It is used while attached to

A bent groove 14 similar to that of the fourth embodiment is provided in the center of the tightening rod 1. An upper hook 21 is provided on the upper surface of one of the tightening rods 1 slightly closer to the bent portion 12 of the bent groove 14. A hooking claw 2 is provided at the tip of the fastening rod 1 on the opposite side of the bent portion 12. The tightening rod 1 is centered on the bent groove 14,
Bend outward. On the inside, even if it is pressed to the maximum, it can only be straight.

A projection or the like may be provided inside the mounting portion 4 (close to the bent portion 12 of the tightening rod 1) to prevent slippage.

If the cross section of the tightening rod 1 is also formed in a shape corresponding to the step of the crimping portion 91 as shown in FIG. After the cross-sectional shape is stepped, the tightening force adjusting element 13
Is provided.

The method of use is to remove the hooking claws 2 and the upper hooking claws 21, widen the tightening rod 1, hold the other side than the spout 92 of the crimping portion 91, and press the upper hooking claws 21 on the other side. Hang it on the rod 1 (also serving as the claw receiver 3) and attach a sealer. When opening the spout 92, the hook 2 is removed and the fastening rod 1 is spread outward. When storing in the refrigerator, the spout 92 is folded, the clamping rod 1 is sandwiched from both sides, pressed, and the hook 2 is hung on the other clamping rod 1 (also serving as the claw receiver 3).

The upper hook 21 may cover the entire upper surface of the mounting section 4. Appearance becomes smart. Further, the opening of the bent groove 14 may be provided on the outside, but unless the opening is widely opened in a V-shape, the tightening rod 1 will not open widely outside. Others are the same as in the fourth embodiment.

This sealer has an effect that it can be easily mounted on the paper pack 9, the spout 92 can be opened and closed while being mounted, and the seal can be easily sealed.

The holding portion 51, which is slightly smaller than the thickness of the crimping portion 91 of the pack 9 and has substantially the same shape as the mounting portion 4, is placed on the folded spout 92 from above while rotating.

The mounting portion 4 and the clamping portion 51 are connected at the upper portion so as to be able to rotate half a turn. As for the cross-sectional shape of the mounting portion 4 and the sandwiching portion 51, a guide 41 is provided in a lower insertion opening as shown in FIG. 6 (R1). The coupling 52 consists of a combination of a small projection and a recess or hole in which this projection fits.

The lower part on the inner side of the mounting part 4 of the clamping part 51 is a part that first hits the spout part 92 when it is put on the spout part 92 from above while rotating. Therefore, when this corner portion is cut obliquely as shown in (Y) so as to be widened outward, it functions as a guide. That is, first, the spout 92
Is inserted according to the rotation in turn, so that the remaining lower portion may not have a guide.

The mounting section 4 is mounted on a side other than the spout section 92 of the crimping section 91 of the paper pack 9. When taking out the contents, the holding portion 51 is raised upward, and the spout portion 92 is opened. The sealer is used while attached to the paper pack 9. When storing in the refrigerator, the spout portion 92 is folded (because the clamping portion 51 is rotatable halfway), and the cover portion 51 is covered while rotating the clamping portion 51 from above.

This sealer is simple in operation and has the effect of being able to seal. Since the sandwiching portion 51 has a U-shaped cross section, it slightly opens due to the elasticity of the material. Therefore, even if the tightening force adjusting element 13 is not provided, it can cope with the thickness variation of the spout 92. , Can be pinched.

The relationship with 1 may be reversed.

In this sealer, when the spout 92 is opened, the holding portion 51 is lifted up and turned a half turn until it comes into contact with the mounting portion 4. And temporarily fixed. When storing in the refrigerator, the insertion portion 92 is covered with the pinching portion 51 and pressed, and the lower temporary fixing claw 23 is fitted into the fitting portion 31 below the mounting portion 4 and is temporarily fixed. Others are the same as in the eleventh embodiment.

When the spout 92 is opened, the sealing device can be temporarily fixed to the mounting portion 4 with the sandwiching portion 51 raised, so that the sealing device does not become an obstacle and can be stored in the refrigerator.
Since the holding portion 51 can be temporarily fixed to the mounting portion 4 while being held between the crimping portions 91, there is an effect that the holding portion 51 does not easily come off and the stability is good.

Incidentally, the temporary fixing claw 23 below the clamping portion 51 and the fitting portion 31 below the mounting portion 4 are temporarily formed by the connecting piece 54, a projection, a concave portion or a hole as shown in (FF) and (GG). You may stop. The relationship between the connection piece 54, the projection, the recess, or the hole may be reversed.

Embodiment 13 Embodiment 13 will be described with reference to FIG. (HH) is a side view showing the entire sealer of Example 13, and (II) is JJ
It is a line sectional view. The sealer of the thirteenth embodiment is also used while being attached to the crimping portion 91 of the paper pack 9.

The sealer of the thirteenth embodiment is different from the sealer of the eleventh embodiment in that the holding portion 4 and the holding portion 51 are provided with holding pieces 45. The holding piece 45 provided on the holding portion 51 can move its tip like the hook 2.

As shown in (II), the cross-sectional shape of the mounting portion 4 is such that the guide 41 extends outward in an eight-shaped manner, and mounting is further facilitated. The cross-sectional shape of the sandwiching portion 51 may be made in this manner. Further, since the serrations 42 are provided on the inner side, the serrations 42 are easy to be attached to the crimping portion 91 and are hard to come off.

When mounting, the holding portion 51 is lifted up obliquely from above, and the holding portion 45 is fitted by pushing the mounting portion 4 obliquely upward. Folded spout 92
When the pinching portion 51 is fitted, the capping piece 45 spreads outward because the tip moves, and automatically fits in the lower portion of the spouting portion 92 when the capping portion 51 is rotated. Others are the same as in the eleventh embodiment.

This sealer has an effect that it is easy to mount, hard to detach, and has good stability.

Embodiment 14 Embodiment 14 will be described with reference to FIG. (JJ) is a perspective view showing the whole of the sealer of Embodiment 14, (KK) is a perspective view showing the whole of another example, and (LL) (MM) (NN) is the manufacturing process, whole, and use of another example. It is a perspective view showing a method. The sealer of the fourteenth embodiment is also used while being attached to the crimping portion 91 of the paper pack 9.

The sealer of the fourteenth embodiment is obtained by extruding the sealer of the eleventh embodiment except for the lids 43 and 53, forming a cut 6 to a predetermined size, and cutting the same.
Continuously extruded material is cut into the length of the sealer, with a cut 6 at the boundary between the mounting portion 4 and the sandwiching portion 51, leaving the upper portion free to bend as a hinge. The processing for forming the cut 6 and the cutting may be performed simultaneously (in one step).

In the case of (JJ), the length of the mounting portion 4 is substantially half the length of the crimping portion 91, and the entire length of the sealer is substantially the same as the length of the crimping portion 91. In the case of (KK), the length of the mounting portion 4 is shortened. (MM) is (KK)
The holding piece 25 is provided above the holding portion 51 of the above.

An advantage of extrusion is that the production cost is low. Further, in the case of (MM), the clip 25 is provided on the upper portion of the clip 51, so that when the spout 92 is opened, the clip 51 is rotated by half a turn so that the clip 25 is crimped. 9
It can be temporarily fixed to 1 and is convenient.

[0120] As for (MM), first, the (LL) is formed by extruding and having the clip 25 at the upper part of the clip portion 51, and then, after the step of cutting 6 and cutting, the clip 25 is formed. Cut off the unnecessary part of. The nipping piece 25 is temporarily fixed with the crimping portion 91 interposed therebetween, and has a cross-sectional shape including a guide portion for facilitating the insertion of the crimping portion 91 and a clamping portion for sandwiching the crimping portion 91.
The gap at the sandwiched portion is slightly narrower than the thickness of the crimping portion 91, so that it is difficult to pull out when the crimping portion 91 is inserted, and to such a degree that it can be pulled out when strongly pulled. The force sandwiching the crimp portion 91 depends on the elasticity of the material.

In this way, it can be manufactured at low cost. Others are the same as in the eleventh embodiment. Since it can be manufactured at low cost, it may be attached to the paper pack 9 at the time of shipment for commercial use in addition to the general use. That is, in the case of relatively expensive contents, there is a paper pack 9 with a spout with a cap (circular), but instead of the spout with a cap, the sealer of this embodiment is attached. Things.

The use of a transparent material is convenient because the expiration date and the like written on the crimping portion 91 of the paper pack 9 can be read. Those having a short length of the mounting portion 4, such as (KK) and (MM), do not hide the expiration date and the like, and can be read well. At the time of shipment, in order to securely attach the mounting portion 4 to the crimping portion 91, the mounting portion 4 may be attached with heat fusion, hot melt, an adhesive, or the like.

If it is manufactured using a harmless substance such as a polyolefin even if it is burned, the problem of dust is safe. Note that these shapes may be manufactured by injection molding. At the time of injection molding, the mounting portion 4 may be further reduced, the thickness may be reduced, or a protrusion or the like may be provided inside.

Embodiment 15 Embodiment 15 will be described with reference to FIG. (OO) is a perspective view showing the entire sealer of Example 15, (PP) is a perspective view of the mounting claw 24 provided on both the mounting portion 4 and the clamping portion 51, and (QQ) is the mounting claw 24. It is a perspective view of what was expanded to the whole end surface. The sealer of the fifteenth embodiment is also used while being attached to the crimping portion 91 of the paper pack 9.

In the sealer of the fifteenth embodiment, at least one of the mounting portion 4 and the sandwiching portion 51 is formed into a two-folded plate shape, and is placed over the crimping portion 91 of the paper pack 9 and sandwiched. It is used by attaching the mounting claw 24. The mounting claw 24 may cover the entire end surface as shown in (QQ). By doing so, the feeling of the nail disappears,
Appearance becomes smart.

The remaining one may have a U-shaped cross section as in the eleventh embodiment, or both may be of a two-fold type. In the two-fold type, the upper parts of the two plate-like objects are connected to bend freely. Both the two-folded type and the U-shaped cross-section may have a bite-blade-like projection or a saw-tooth-like projection on the inside. The two-fold type is provided with a clamping force adjusting element 13 inside.

[0127] The usage method is as follows.
The user presses the crimping portion 91 from above and presses it, and puts on the mounting claw 24 to mount it. When the mounting portion 4 has a U-shape, the mounting portion 4 is mounted from above.

As in the eleventh embodiment, the holding portion 51 is covered while rotating from above. The two-folded one is pressed and the mounting claw 24 is hung. When removing, the mounting claw 24 may be removed. Others are the same as in the eleventh embodiment.

This sealer is easy to fit because it only needs to be folded over from above and pressed. Easy to remove.

Embodiment 16 Embodiment 16 will be described with reference to FIG. (RR) is a perspective view showing the entire sealer of Example 16, (SS) is a perspective view showing a state where the slide piece 8 is pulled sideways and the compression piece 7 is spread, and (TT) is a sectional view taken along the line KK. (The tightening force adjusting element 13 is omitted). The sealer of the sixteenth embodiment is also used while being attached to the crimping portion 91 of the paper pack 9.

The sealer of the sixteenth embodiment differs from the sealer of the fifteenth embodiment in the basic concept. To tighten the spout 92 of the paper pack 9, the slide piece 8 and the compression piece 7 are used.
Is used. The compression piece 7 is in direct contact with the crimping portion 91 of the paper pack 9, the slide piece 8 slides outside the compression piece 7, and tightens the crimping portion 91 via the compression piece 7.

The compression piece 7 has an elongated U-shape.
A hooking claw 2 and a claw receiver 3 are provided at both open ends.
The hook 2 can be moved by thinning the base. A protrusion 73 is provided at the base of the hook 2 on the outside.

The two plate portions may be thin, and a bent groove 71 is provided at the center so as to be bent outward. Bent groove 7
The mounting portion 4 is provided between the connecting portion 1 and the connecting portion 72, and is mounted on the crimping portion 91. A portion between the bent groove 71 and the tip portion is the fastening portion 5 and presses the spout portion 92. A tightening force adjusting element 13 is provided inside the compression piece 7.

[0134] The slide piece 8 also has an elongated U shape, but is thick and does not deform. Projection 7 of hook 2
A shallow concave portion 81 is provided inside the distal end of the slide piece 8 to be hit by 3, and the protrusion 73 at the base is fitted.

Between the pressing piece 7 and the slide piece 8, as shown in (TT), the slide piece 8 does not come off upward (TT).
A slide recess 82 and a slide protrusion 74 are provided. The slide concave portion 82 and the slide convex portion 74 may be provided with a thin one at the center of the slide piece 8 or the compression piece 7, or may be of a type that is fully vertical. Also, the relationship between concave and convex is
It may be reversed.

For use, the slide piece 8 is pulled sideways, the compression piece 7 is opened in a V-shape, and the mounting portion 4 is
Attach to When opening the spout 92, the slide piece 8 is kept pulled. When the spout portion 92 is folded and sealed, when the slide piece 8 is pushed, the compression pieces 7 are pushed and narrowed, and finally come into contact with each other, and
Hangs on the claw receiver 3 and is sealed. Protrusion 7 at the base of hook 2
3 fits into the concave portion 81 of the slide piece 8, so that the slide change 8 is fixed.

When the closed spout 92 is opened, when the slide piece 8 is pulled, the projection 73 fitted in the concave portion 81 is pulled and the hook 2 is released, so that the compression piece 7 is opened. When the slide piece 8 is further pulled to the bent groove 71, the spout 92 can be opened.

This sealer can be used while being attached to the crimping section 91, and the slide piece 8 need only be slid in the horizontal direction, so that the operation is simple, and the seal and opening can be performed. In addition, since the hooking claw 2 and the claw receiver 3 are provided at the distal end of the pressing piece 7, the tightening is reliable, and an unreasonable load is not applied to the slide piece 8. Although plastic has a phenomenon called creep, which is deformed when an external force is applied for a long time, it has the effect of preventing creep.

Embodiment 17 Embodiment 17 will be described with reference to FIG. (UU) is a perspective view showing the entire sealer of Example 17, (VV) is a perspective view showing the entirety of another example, (WW1) is a sectional view taken along line LL,
(WW2), (WW3), and (WW4) are LL of another example.
It is a line sectional view. Example 17 is also a slide type,
The pressing piece 7 is not provided, and the sliding piece 8 directly contacts the crimping portion 91. When opening the spout 92, the slide piece 8 is pulled.

The slide piece 8 has an elongated U-shape, is thick and does not deform. The interval between the two slide pieces 8 is slightly smaller than the thickness of the crimp portion 91. Slide piece 8
Is adjusted according to the material, the shape and thickness of the U-shaped connecting portion, and the inserted crimping portion 91 can slide so that the contents do not leak from the spout portion 92.

As shown in (UU), an open figure-shaped guide 41 is provided at the open end so that the crimping portion 91 can be easily inserted. The cross-sectional shape may be rectangular, or a corrugated portion may be provided on the inner side in contact with the crimp portion 91 so as to be slippery. A holding piece 45 is provided below the closed connecting portion.

As shown in (VV), the open end is
The V-shaped guide 41 may be used, and the connecting portion at the other end may be in a bulged shape for reinforcement. The inflated shape provides a clue when the slide piece 8 is moved in the lateral direction, and has an advantage of being easy to hold.

The cross-sectional shape is as shown in (WW1).
The provision of the slide recess 32 and the slide recess 82 has the advantage that the elasticity of the crimping portion 91 can be utilized outside the slippery portion. When it is formed in a U-shape as in (WW2), it becomes a reinforcing rib to save material, and since the pressure receiving area is small, the spout 92 is well tightened and slippage is improved.

By forming a U-shape as in (WW3) and making one bite slightly into the other, there is an advantage that the elasticity of the crimping portion 91 can be utilized in addition to being slippery. (WW
Make the U-shape and the Y-shape face inward as in 4),
Further, if the central portion of the Y-shape is slightly protruded so as to bite, there is an advantage that the elasticity of the crimping portion 91 can be utilized in addition to slipperiness. The ribs may extend outward.

For use, the opened spout portion 92 is folded, the guide 41 of the slide piece 8 is fitted beside the spout portion, the slide piece 8 is pushed in the lateral direction, and the spout portion 92 is tightened and sealed. The holding piece 45 is inserted into a lower portion of the crimping section 91. When opening the spout 92, the slide piece 8 is removed by pulling it in the lateral direction.

Alternatively, the slide piece 8 may be fitted from the crimp portion 91 and the folded spout portion 92 may be tightened. In this case, when the slide piece 8 is pulled to the center of the crimping portion 91, the spout 92 can be opened with the slide piece 8 attached.

Since this sealing device does not have the hook 2, the guide 41 of the slide piece 8 is slightly opened. Accordingly, it is possible to cope with a variation in the thickness of the crimping portion 91 and the spout portion 92 by acting as a cushion.

This sealer can be easily mounted because it only needs to be sandwiched from the side of the crimping section 91, and has the holding piece 45 so that it does not easily come off naturally. There is good. Also, since it can be molded integrally with plastic, there is an effect that it can be manufactured at low cost.

Embodiment 18 Embodiment 18 will be described with reference to FIG. FIG. 18 is a perspective view showing the entire sealer of the eighteenth embodiment. Example 18
Is basically different from the ones up to the seventeenth embodiment in that it is sandwiched from above the folded spout 92. A plate-shaped auxiliary piece 55 is connected to a lower part of a sandwiching portion 51 having a U-shaped cross section so as to be freely bent.

A rail-shaped projection with a sharp tip may be provided on the inner side of the holding portion 51, or a step may be provided according to the shape of the crimping portion 91. The rail-shaped protrusions are
, And the force is concentrated on one line, so that sealing is ensured. The length of the sandwiching portion 51 may be approximately half the length of the crimping portion 91 since the folded spout 92 may be sandwiched. It may be slightly longer to allow for room.

If the height of the sandwiching portion 51 is reduced, the force for sandwiching the spout 92 increases. You may make the upper part of the pinching part 51 bulge (increase the wall thickness) to enhance the pinching force. When the length of the auxiliary piece 55 (in the direction perpendicular to the length of the sandwiching portion 51) is adjusted to the length of the inclined portion (corresponding to the roof) of the paper pack 9,
It does not get in the way when stored. Of course, the auxiliary piece 55 may be shorter.

If the auxiliary piece 55 is slightly downwardly formed at the time of molding, the auxiliary piece 55 may be perfectly attached to the inclined portion at the time of mounting. The tip of the auxiliary piece 55 may be bent slightly downward so as to fit on the shoulder portion (corner) of the paper pack 9. It also serves as a clue when raising the auxiliary piece 55 upward. This sealer may be manufactured by cutting an extruded product into a certain size.

When the auxiliary piece 55 is bent until it reaches the holding portion 51 and both of the auxiliary pieces 55 are pushed inward, the inside of the holding portion 51 opens according to the leverage principle. The part 92 is sandwiched from above and sealed. Both auxiliary pieces 55 are made to fit along the roof of the paper pack 9.
When opening the spout 92, both the auxiliary pieces 55 are raised and pushed inward to expand the inside of the sandwiching portion 51, and the sealer is removed.

Since the auxiliary piece 55 is long, the holding portion 51 can be easily opened according to the principle of leverage, and can be easily attached. The shape is very similar to the shape of the paper pack, so it does not become bulky when installed. Because it can be molded integrally with plastic, it can be made cheaply. Those molded by extrusion and cut to a certain size can be cheaper than those made by injection molding.

[0155]

According to the sealer of the present invention, the spout 92 can be easily attached to and detached from the paper pack 9 and can be sealed or opened with a simple operation.
The used paper pack 9 can be put into the refrigerator in a lying state, and the space in the refrigerator can be saved.
