Description

[Detailed description of the invention] (Industrial application field) This invention relates to canning.

(Prior Art) Many designs of cannibals have been known so far, but few have been found that are actually satisfactory. In many cases, the blade tends to get stuck and become stuck, or the cut end becomes jagged, posing a danger to the user. In addition, fine metal debris is generated, which may contaminate the contents of the can.

(Problems to be Solved by the Invention) Therefore, an object of the present invention is to provide an improved canister that can sufficiently and easily perform functions that the prior art could not perform.

SUMMARY OF THE INVENTION According to the invention, the can is intended to be cut around the lower sides of its lid and lip to separate the lid and lip from the rest of the can. A can cutter is provided, such a can cutter including a pair of body members pivotally connected relative to each other;
Each of these body members extends from a pivot point formed integrally with the main body member to a position normally separated from the pivot point, and is movable between an open position and a closed position, and can be grasped by the user with one hand to set the closed position. a handle shaped like a can, a shaft attached to a drive wheel that contacts the lip of the can lid and rotatable to pivot the can cutter around the top of the can via the drive wheel, and a cutting operating position. a cutting wheel having a cutting blade forming a lip with the drive wheel at the can, pressing against and passing through the side of the can, and cutting around the can as the can cutter pivots around the can; A cutting operation position in which the cutting blade is pressed against and penetrates the side of the can by the drive wheel, and a non-cutting position in which the cutting wheel is spaced from the drive wheel, for example, approximately radially away from the drive wheel relative to the axis of rotation of this drive wheel. a mounting plate slidably supported by one of the main body members so as to be movable to and from an operating position, and a cutting wheel rotatably mounted thereon; a cam mechanism for moving the handle to a cutting operating position when the handle is rotated toward a closed position, and for moving the handle to a non-cutting operating position when the handle is rotated from its closed position rotational limit toward an open position; The cam mechanism includes a groove provided in one of the mounting plate and the main body member on the side that does not support the mounting plate, and a pin provided in the other, and the pin is inserted into the groove. The protrusion and the groove are formed to be inclined at a predetermined angle with respect to the sliding direction of the mounting plate.

The functions and effects of the present invention are as follows.

(Function) In the present invention, the cam mechanism consists of a groove provided in one of the mounting plate and the main body member on the side that does not support the mounting plate, and a pin provided in the other, and the pin protrudes into the groove. Also, since the groove is formed at a predetermined angle with respect to the sliding direction of the mounting plate, the mounting plate moves reliably following the opening and closing of the handle, and the cutting wheel cooperates with the drive wheel when the handle is closed. It can be moved into a cutting position where it penetrates the side of the can, and into a non-cutting position away from the drive wheel when the handle is opened. Therefore, when the handle is opened and the drive wheel is placed on the lip of the can lid, and the handle is closed in this state, the cutting wheel penetrates the side of the can, and by rotating the drive wheel with the handle closed, the can is closed. The entire circumference of the side can be cut with a cutting wheel. When the handle is then opened, the cutting wheel moves away from the drive wheel.

(Effects) (a) The cutter of the present invention consists of a groove provided in one of the mounting plate and the main body member on the side that does not support the mounting plate, and a pin provided in the other, and the pin protrudes into the groove. In addition, by adopting a cam mechanism in which the groove is inclined at a predetermined angle with respect to the sliding direction of the mounting plate, the cutting wheel can be moved to the cutting operation position and from the cutting operation position without cutting by simply operating the handle. Since the lid can be moved to the desired position, the cut lid, which is sandwiched between the drive wheel and the cutting wheel after cutting, can be easily removed.

The groove from which the pin protrudes is inclined at a predetermined angle with respect to the sliding direction of the mounting plate, and by setting this angle appropriately (including making the groove curved as a whole), the handle The opening/closing angle of the handle and the positional relationship of the cutting wheel with respect to the drive wheel, for example, by first narrowing the angle slightly as the handle moves from its open state to its closed state, the cutting wheel moves a sufficient distance relative to the drive wheel, and the handle closes. The structure can be such that the moving distance becomes shorter as the state approaches the state, so that a sufficient penetrating force is exerted on the side surface of the can. Therefore, there is an advantage that the canning operation can be performed quickly and reliably.

C. When the handle is closed and the cutting wheel penetrates the side of the can, the handle is in its most compact form, making it easy for the operator to hold with one hand, and by turning the drive wheel with one hand, canner cutting can be done easily. can.

D. In this way, the cutting wheel can penetrate the side of the can and the subsequent canning operation can be performed reliably by rotating the drive wheel, so a very clean cut can be obtained without the cut being jagged. In addition, almost no metal debris is generated. Furthermore, if the can is equipped with a lid that has a lip that the drive wheel touches, this canning operation can be performed without being affected by the shape of other parts such as the sides, so the can can be seriously damaged. Even if there is a dent, the cutting operation can usually be performed without any problems. For similar reasons, such cans can be used both for ordinary cylindrical cans and for other cans, such as oval or rectangular cans.

Preferably, the axis of the manually rotatable shaft to which the drive wheel is attached coincides with the rotation axes of the two body members.

The cutting wheel is moved into the cutting operating position by means of a cam mechanism by only slight rotations of the body part, with the body part opening at an angle of, for example, a maximum of 30[deg.]. The rotation of the body member can be limited in its range, such that, for example, opening the cutting nip between the drive wheel and the cutting wheel requires the handle to be rotated by more than about 180°. UK Patent Application No.
8303320 and has advantages over the Kan-kiri described in Publication No. 2118134.

The cam mechanism is formed in the main body member on the side that does not slidably support the mounting plate, and includes, for example, a substantially linear groove that is inclined at a predetermined angle with respect to the sliding axis of the mounting plate, and a groove that extends from the mounting plate. A pin protruding into the groove can be formed, and the arrangement of the groove and the pin can also be reversed. It is also preferred that the groove be inclined at an angle of about 75 DEG relative to the direction of inclination of the mounting plate when the handle is in the closed position, although such angle may vary, for example, from 80 DEG to 60 DEG. In fact, if such a groove is formed in the body member on the side that does not support the mounting plate as described above, the relative angle of the groove to the sliding direction of the mounting plate will be such that the handle is in its closed position and in its open position. It changes as you move between. That is, as the handle moves from its closed position to its open position, the angle becomes larger and the mechanical properties also change.
Therefore, as the handle moves from the open state to the closed state, the cutting wheel is initially rapidly moved forward relative to the mounting plate, but as the cutting wheel approaches the can, the forward movement slows down.
The advantage is that the can can be penetrated with relatively high forces.

In addition, by engaging with the groove of the pin, the mounting plate can reliably follow the opening and closing of the handle, moving away from the drive wheel when the handle is open, and moving toward the drive wheel when the handle is closed. There is no need for the user to move the wheel by hand.

Additionally, as mentioned above, an upright protective member is integrally formed on the main body member on the side that does not support the mounting plate, and this protective member prevents the user from accidentally touching the cutting wheel. is preferred.

Additionally, the body member on the side that does not support the mounting plate has a mechanism for disengaging or releasing the lid of the cut can from the nip between the cutting wheel and the drive wheel when the cutting wheel is moved to the non-cutting position. Preferably, a functional abutment is provided. Such an abutment can also be an edge which is sloped in the direction of movement of the cutting wheel between the cutting and non-cutting positions; It can be constituted by the end of the member.

The drive wheel and the shaft connected to it can be driven manually, for example via a two-armed crank mounted on the free end of the shaft. Alternatively, the can cutter can be a hand-held electric can cutter, and a housing for an electric motor can be added to one of the handles, so that the shaft can be driven by the electric motor.

(Example) Next, an example of the present invention will be described with reference to the drawings.

The illustrated canker 10 has two body members 12 and 14. These main body members 12,
14 are mutually rotatable around a hollow upright cylindrical insertion portion 15 provided in the other body member 12, which protrudes into a circular hole 15a formed in one body member 14. . The shaft 16 extends in the axial direction through the insertion portion 15 and the hole 15a (see FIG. 4). Therefore, the main body member 12,1
4 is rotatable between the closed position shown in FIG. 1 and the open position shown in FIG.

The body members 12, 14 have integrally formed handles 12a, 14a, respectively, which extend in a direction away from the axis of the shaft 16, and in the closed state shown in FIG.
They are arranged so that they are close to each other and in a parallel state. Conveniently, body members 12, 14 are formed from a synthetic plastic material, such as polypropylene.

At one end of the shaft 16 is a crank 20 with two arms for manually rotating the shaft 16.
are integrally formed. A metal reinforcing shaft 22 is embedded in the shaft 16, and one end of the reinforcing shaft 22 projects slightly beyond the end of the shaft 16 and is attached to a drive wheel 24. The drive wheel 24 is dish-shaped and has peripheral teeth 26 that frictionally engage with the lip 28 (see FIG. 6) of the lid 27 of the can 29, so that the can cutter 10 can be driven around the can 29 during operation. It is becoming.

A rectangular metal plate 30 is slidably attached to the main body member 12 only along its longitudinal axis 30a (see FIGS. 1 and 3).
Projecting outwardly from one side of the metal plate 30 is a pin 32 to which a sleeve 34 of synthetic plastic material is rotatably attached. A metal cutting wheel 36 is connected to the sleeve 34 at its outer position and has a sharp circular cutting blade 37 . The sleeve 34 is intended to abut the lip 28 of the can 29 and rotates as the can cutter 10 moves around the can 29;
Further, since the cutting wheel 36 is also rotatable together with the sleeve 34, they rotate at the same time. A washer 38 is attached to the outside of the cutting wheel 36, and the sleeve 34, the cutting wheel 36, and the washer 38 are fixed in position by crushing the end of the pin 32.

The main body member 12 has an upright U-shaped protection member 39.
are integrally formed. This prevents the user from being accidentally cut by the cutting wheel 36. The protective member 39 has an edge 39a at its end that is inclined with respect to the shaft 30a. At the final stage of the canning operation, the cut lid is moved between the cutting wheel 36 and the drive wheel 2.
The state is maintained between 4 and 4. Therefore, when the cutting wheel is pulled away after the can has been opened, the can lid abuts the edge 39a and is forced away from the vicinity of the blade of the cutting wheel 36 and automatically released for disposal.

A cam pin 40 protrudes from the opposite surface of the metal plate 30. The cam pin 40 engages in a groove 44 formed in the main body member 14. This groove 44 is connected to the shaft 30a when the handle is in the closed state.
The metal plate 30 is formed in a substantially straight line at an angle of approximately 75° to the metal plate 30 as the handles 12a and 14a move between the open position shown in FIG. 3 and the closed position shown in FIG. is the fourth from the bottom position
Move between the upper cutting operation position shown in the figure. As a result, the cutting wheel 36 is also configured as shown in FIG. From the non-cutting operating position, the cutting blade 37 will be moved to the cutting operating position shown in FIG. 1, in which it slightly overlaps the drive wheel 26.

Since the groove 44 is formed in the main body member 14,
The angle of groove 44 relative to the sliding direction of metal plate 30 changes as handles 12a, 14a move between their closed and open positions. That is, such an angle increases as the handles 12a, 14a move from the closed position to the open position,
Mechanical features will also change. Therefore, as the handles 12a, 14a move from their open positions to their closed positions, the metal plate 30 causes the cutting wheel 36 to advance relatively rapidly at first, but as it approaches the can 29, the forward movement slows down. The advantage is that the sides of the can 29 can be penetrated with relatively large forces.

FIG. 6 also shows the cutting operation state,
In the figure, the cutting blade 37 has passed through the upper end of the cylindrical side surface of the can 29 directly adjacent to the lid 27. Therefore, when turning the crank 20, the
When the can 9 is cylindrical, the can cutter 10 is driven to rotate in a circular manner around the upper part of the can 29, and the can 29 is cut into a circular shape by the cylindrical side surface adjacent to the upper part. When such a circular cutting operation is completed, the top of the can is lifted completely apart and held between the cutting wheel 36 and the drive wheel 24, with the handles 12a, 14a in the open position shown in FIG. When you reach it, the cut off upper part is Edge 3.
It comes into contact with 9a and is removed.

A metal plate 45 is provided on one side of the main body member 12.
is embedded therein, and this plate 45 is provided to protect the plastic material of which the body member is made in the event that it comes into contact with the rim of the can during the canning operation. Further, the surface of the plate 45 slightly protrudes from the main body member 12.

To assist in maintaining the cutting position during the cutting operation, the main body member 12 is integrally formed with a small projection 46 that projects substantially parallel to the axis of the shaft 16. The end of this protrusion 46 comes into contact with the top surface of the lid 27 and serves to maintain the relative height of the canker.

The can cutter 10 as described above is easy to manufacture and operate, and can keep the can clean and sanitary.
