Abstract

(57) [Summary] [Purpose] The main purpose is to open a can of canned food very easily and surely without any effort. [Structure] A cutting blade 8 is provided at a lower end portion of a shaft 3 having a spring 3 mounted thereon, and a lid plate b of a can of a which can be fixed to a support frame B by an operation of descending rotation of the shaft 3 is rotationally cut and opened. .

Description

[Detailed description of the device] [Industrial applications]

[0001]   This invention is a can that tries to open the can quickly, safely and surely without any effort. The present invention relates to a cap opening device.

[Prior art]

[0002]   Recently, the demand for sealed containers such as canned foods has increased with the rapid growth of stored foods. Most of the means for opening such canned food are to open the cutting edge directly using a can opener. The lid was manually opened by rotating it.

[Issues to be solved by the device]

[0003]   However, in the case of the above manual opening of the lid, the fingers are cut at the mouth of the can when the lid is opened. It was impossible to open a large amount of cans in a short time.

[Means for Solving the Problems]

[0004]   This invention is intended to improve the above-mentioned drawbacks, and as shown in FIG. A connecting holder 1 for the rotary drive mechanism A is provided on the upper part, and a cutting blade having an appropriate shape on the lower part. The shaft 3 mounted with 8 is moved up and down about the rod 6 by the action of the spring 2. Canned articles that are movably supported and can be placed in the support frame B by rotating and lowering the shaft 3. The lid plate b of a is configured to be opened while the cutting blade 8 is rotationally incised. It is intended to provide a can opener.

Further, the spiral groove 3a is formed on the surface of the shaft 3 and the spiral groove 3a is formed. 3a is spirally combined with the spiral shaft hole 4a of the metal 4, and the above-mentioned spiral system action is used to The shaft 3 is automatically driven to rotate up and down, and when the shaft 3 is rotated and lowered, The lid plate b of the canned food a that can be placed in the support frame B is opened and closed by the tip cutting blade 8. It is also a consideration.

[Action]

[0006]   This invention has the above-mentioned structure, and when opening the canned food a, First, the can a is placed in the support frame B, and then the connecting holder 1 is attached to the rotary drive mechanism A. The shaft 3 is connected to the spring 2 by interlocking with and generating power. By the action, it can move up and down while rotating around the rod 6.   In such a state, the shaft 3 is gradually driven to be pressed downward. The cutting blade 8 attached to the tip of the shaft 3 rotates in a circular shape, and the cutting edge 8a It is possible to open the lid plate b of the can of food a by opening the lid so that the lid can be easily and surely opened.

[0007]   In addition, the above-described spiral vault having the shaft 3 formed with the spiral groove 3a is used. A structure in which the grooved shaft 3 is supported in a spiral shaft hole 4a of a metal 4 in a spiral system. Therefore, the shaft 3 is automatically rotated by the above-mentioned spiral action at the same time as the rotation of the shaft 3. The lid plate b of the canned food a, which is rotated and lowered by itself, and placed in the support frame B, is rotated by the cutting blade 8. The lid may be easily opened by opening.

【Example】

[0008]   An embodiment of the present invention will be described below with reference to the drawings. Holder 3 for connecting A is attached with a cutting blade 8 of an appropriate shape at the bottom of the shaft 3 by a shaft. ing.   Outside the shaft 3, the spring 2 is provided between the holder 1 and the upper canister 5. The winding-provided shaft 3 is elastically supported in the axial direction.   The support frame B is such that the upper can receiver 5 and the lower can receiver 9 are fixed vertically by the support bar 7 as described above. The rods 6 are formed at intervals, and several rods 6 are supported inside the upper and lower sides of the cutting blade 8. Guide the movement.   In the above structure, the can a for the purpose of opening the lid is placed below the support frame B. After that, the rotary drive mechanism A is pushed downward while gradually rotating it manually or manually. By squeezing, the shaft 3 rotates downward against the elastic force of the spring 2, One of the cutting blades 8 rotates in a circular shape, and while rotating the cutting edge of the lid plate b of the can of food a with the cutting edge 8a, It is possible to open the lid.   Further, the spiral groove 3a is formed on the surface of the shaft 3 and the spiral groove 3a is formed in the metal 4. By forming a spiral system in the spiral shaft hole 4a to be engraved in the The shaft 3 is automatically moved up and down by simply rotating it. It may be possible to request a lid opening operation.   In addition, the cutting blade 8 is replaceably supported by a tool that fits the can diameter of the lid to be opened. By forming the shape of these cutting edges 8a into an uneven shape such as a corrugated shape as shown in FIG. It goes without saying that the incision action is performed more reliably and appropriately.

[Effect of device]

[0009]   As described above, in this invention, the cutting blade 8 is rotatably supported on the support frame B. Therefore, by simply rotating the shaft 3, the lower cutting blade 8 opens the canned lid. It is possible to perform it stably and efficiently and surely. Once again, the risk of manually contacting the blade edge with the can lid surface is fundamentally eliminated. Of course, it also has the effect that a large amount of lids can be easily opened.
