DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a base opener for opening bases (lids) of various containers.

[0002]

2. Description of the Related Art Various types of openers are known for opening when a base of various containers is tight, but can be used for a wide base, without damaging the base. And yet, nothing useful was known.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a die opener capable of meeting such a demand.

[0004]

SUMMARY OF THE INVENTION A die opener according to the present invention comprises: a grip handle; an opener belt made of a loop-shaped elastic material having one end fixed to the grip handle and the other end movably supported by the grip handle. And uneven teeth formed on the outer surface of the moving portion of at least the grip handle of the opener belt; and when the portion having the uneven teeth of the opener belt is linear, the relative movement of the opener belt is allowed, And a tooth holding member provided on a grip handle, which engages with the uneven teeth when bent so as to be inward and does not allow relative movement thereof.

It is desirable to form a movement guide groove of the opener belt on the grip handle. Further, if the opener belt is made of an elastic material having repeated adhesiveness or an elastic material having an inner surface roughened, more preferable adhesion to the die can be obtained.

[0006] The tooth pressing member moves the opener belt in a direction in which the loop becomes smaller, and a lock convex portion which fits in the concave portion of the concave and convex teeth when the opener belt is bent so that the concave and convex teeth are inside. In this case, it is preferable to provide a tapered surface for guiding the convex portion of the uneven tooth toward the grip handle side, and a movement preventing surface capable of contacting the convex portion of the uneven tooth when the opener belt is moved in a direction in which the loop becomes larger.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present die opener is large and comprises a grip handle 10, an opener belt 20, and a tooth presser member 30. The grip handle 10 has a columnar shape large enough to be gripped by one hand, and has, at one side corner of one end thereof, a belt fixing portion 11 formed of an inclined wall obtained by cutting off a corner of a columnar body, On the other side, a belt movement guide groove 12 is provided. An engaging portion 13 of the tooth pressing member 30 is formed above the moving guide groove 12. This locking part 13
Is composed of a pair of left and right introduction groove locking portions 13a and locking grooves 13b one step deeper than the introduction groove locking portions 13a.
A retaining edge 12a is formed in the movement guide groove 12 below the locking portion 13 so that the space of the movement guide groove 12 has a U-shaped cross section or a dovetail groove shape. This grip 1
0 is preferably made of a synthetic resin material or wood.

The opener belt 20 is made of an elastic material such as rubber, and has on its outer surface uneven teeth 23 in which concave portions 21 and convex portions 22 are formed alternately and continuously. The opener belt 20 is preferably made of, for example, an elastic material having repeated tackiness or an elastic material having a rough surface on the inner surface that can be visually confirmed. A slide operation projection 24 is fixed to a distal end of the opener belt 20.

One end of the opener belt 20 is fixed to the belt fixing portion 11 of the grip 10 via a fixing tool 15 and a fixing screw 16. The fixing device 15 has a triangular prism shape corresponding to a shape obtained by cutting off a columnar body to form the belt fixing portion 11, and a concave portion 21 and a convex portion of the opener belt 20 are provided on a surface facing the belt fixing portion 11. A projection 17 and a depression 18 corresponding to 22 are formed. Fixture 1
The fixing member 15 is fixed to the belt fixing portion 11 with the fixing screw 16 in a state where the convex portion 17 and the concave portion 18 of the fifth member 5 are fitted to the concave portion 21 and the convex portion 22 of the opener belt 20, thereby forming one end of the opener belt 20. Is fixed to the grip handle 10. The other end of the opener belt 20 has a loop shape and is slidably guided in the movement guide groove 12.

The tooth holding member 30 is made of a metal material or a synthetic resin material. The left and right lock arms 31 locked by the locking portions 13 of the grip 10 are engaged with the right and left lock arms 31. The lock arm 31 has a substantially U-shaped cross section having a wall 32, and a lock claw 31 a that fits into the lock groove 13 b of the lock portion 13 is formed at the tip of the lock arm 31. At the upper end of the engaging wall 32, a lock convex portion 33 is formed which fits into the concave portion 21 when the opener belt 20 is bent so that the concave and convex teeth 23 are on the inner side. On the surface facing the guide groove 12, a taper surface 34 for guiding the convex portion 22 of the uneven tooth 23 to the bottom of the moving guide groove 12 when the opener belt 20 is moved in a direction in which the loop becomes smaller, and an opener belt 20. When moving the loop in the direction in which the loop becomes larger, the uneven teeth 23
And a movement preventing surface 35 which stops the movement by contacting with the convex portion 22 of the projection.

The present die opener has a dovetail formed by a retaining edge 12a which guides a free end of an opener belt 20 having one end fixed to a belt fixing portion 11 of a grip handle 10 to a movement guide groove 12. The tooth holding member 30 is fitted into the groove, and the tooth holding member 30 is gripped from above the opener belt 20.
To the locking portion 13. The tooth pressing member 30 may be fixed to the locking portion 13 in advance. Opener belt 2
When adjusting the size of the loop of 0 to the size of the base,
The opener belt 20 in the portion of the tooth presser member 30 is made substantially linear, and is slid in the moving guide groove 12.

When the opener belt 20 is moved in a direction in which the loop becomes smaller, the tapered surface 34 of the tooth presser member 30 moves the convex portion 22 of the uneven tooth 23 into the moving guide groove 1.
The movement of the opener belt 20 in the direction in which the loop becomes larger is not smooth when the opener belt 20 is moved in the direction in which the loop becomes larger.
The opener belt 20 is moved while being pressed against the bottom side of the moving guide groove 12 because it may come into contact with the convex portion 22 of the moving guide groove 12. Usually, the work to enlarge the loop of the opener belt 20 is usually performed by removing the base opener from the base, whereas the work to reduce the loop is performed by moving the opener belt 20 along the base. Therefore, it is preferable to enhance workability and operability. On the other hand, when the loop is enlarged, the opener belt 2 is used.
If the resistance of 0 is small, there is a possibility that the opener belt 20 may come off the grip 10 (the locking portion 13) carelessly. When the opener belt 20 slides, the slide operation protrusion 24 can be used.

When the size of the opener belt 20 is matched with the size of the base and the grip handle 10 is turned in the direction in which the base is opened, the opener belt 20 is set so that the concave and convex teeth 23 are located inside the tooth holder 30. It bends and the lock projection 33 of the tooth presser member 30 fits into any of the recesses 21. In this state, the opener belt 20 does not move with respect to the tooth presser member 30, that is, the grip 10, and the size of the loop is fixed, so that a rotational force is applied to the base inside the opener belt 20. When the grip 10 is rotated, the base can be opened.

As is clear from the above description, the present die opener does not need to select the size of the die as long as the size of the loop of the opener belt 20 can be adjusted. Since a large rotating force can be given, the opening can be surely performed. Since the opener belt 20 is made of an elastic material, there is no possibility of damaging the base.

The pitch between the concave portion 21 and the convex portion 22 of the concave and convex teeth 23 of the opener belt 20 can be appropriately selected.
In addition, the uneven teeth 23 need only be formed at least at positions corresponding to the tooth holding members 30, that is, at portions where the movement guide grooves 12 of the opener belt 20 slide, and need not necessarily be formed over the entire opener belt 20. .

[0016]

According to the present invention, it is possible to obtain a die opener which can be used with a wide die, does not damage the die, and is easy to use.
