Description

[Detailed Description of the Invention] The present invention relates to a squeezer used for squeezing milky products in tubes.

Conventionally, a V-shaped insertion opening is provided at the top, and a winding rod with a long groove formed on the circumferential surface and a knob at one end is inserted into the cavity of the vessel, which has a cavity at the bottom of the insertion opening. A tube extractor in which a winding rod is pressed against the bottom of the tightening part by a spring plate attached to the container body is known from Japanese Utility Model Application No. 48-6148. In this case, the winding rod is pressed against the tightening part by a leaf spring, so when the tube is wound up, the tube rubs against the tightening part and creates winding resistance, making it difficult to wind up the tube.

Even if the winding rod is pressed against the tightening part by a leaf spring, it will prevent the winding rod from falling off and wobbling during rotation, but it will not prevent the winding from returning, which occurs in the case of an elastic tube. It cannot be used to squeeze out plastic tubes, which are often used these days.

In addition, a tube-shaped container extruder in which a pair of rolls are rotated in opposite directions by interlocking gears, a ratchet gear is attached to one of the rolls, and a idler wheel with a handle is engaged with this ratchet was invented in the 1980s. It is known from the publication No. 49-131253.
In this method, the tube is pulled in and squeezed by the rotation of the roll, so the tube cannot be squeezed reliably due to the slip. The constricted part of the tube protrudes toward the handle, making it inconvenient to operate the handle. Since the ratchet mechanism is not equipped with a claw release means, the tube drawn between the rolls must be forcibly pulled out from between the rolls, which increases the force and tends to break the device. Since there are many parts and assembly is troublesome, it cannot be manufactured at low cost. Once assembled, it is impossible to disassemble and wash each part individually.

In contrast, the present invention provides a space for winding the tube under the V-shaped throttle opening, has a pawl wheel chamber adjacent to the main body with bearing holes on both side walls, and has a pawl and a pawl remover in this pawl chamber. A fixing piece to which a stopping arm with a knob is attached is accommodated, the center hole of the fixing piece is aligned with the bearing hole of the main body, and a winding shaft with a slot and a ratchet wheel and a knob is inserted into both holes. However, by installing a retaining ring between the ratchet wheel and the side wall of the ratchet wheel chamber, it can be easily assembled with a small number of parts, the tube can be easily attached and detached, and even plastic tubes etc. do not unwind. Another object of the present invention is to provide an inexpensive and convenient tube wringer that can be disassembled into pieces and washed individually.

Next, an embodiment of the tube wringer according to the present invention will be explained based on the drawings.

1 to 4 of the drawings, 1 is a main body molded from synthetic resin, with a V-shaped aperture 2 provided on its upper side, a tube winding space 3 provided below this aperture 2, and side walls. Bearing holes 4, 4 are provided in the bearing holes 4, and a notch b is provided on one of the bearing holes 4 and communicates with the bearing holes 4.
has been formed. Reference numeral 5 denotes a ratchet wheel chamber adjacent to one side of the main body 1, and a hole 6 is provided in the side wall for allowing the ratchet wheel (to be described later) to enter and exit. Reference numeral 7 denotes a hollow winding shaft of a tube 8 which is inserted into the bearing holes 4, 4 and has an open part c at one end, and has a cut 9 on the circumferential surface through which the bottom tightening part of the tube 8 is inserted through the open part c. A rotating knob 10 is provided at the other end, and a ratchet wheel 11 is provided inside the knob 10 to be inserted into the ratchet wheel chamber 5 through a hole 6 in the side wall. Reference numeral 12 denotes a fixing piece housed in the pawl wheel chamber 5. The central hole 13 is fitted into the winding shaft 7, the outer edge is brought into contact with the inner wall of the pawl wheel chamber 5, and the locking pin 14 is engaged with the notch 15 in the side wall. It has been combined. 16 is the fixed piece 1
2 is a stop arm attached along the outer periphery of the ratchet wheel 11, and a stop claw 17 that engages the ratchet wheel 11 is provided at the bottom of the arm.
is attached, and a knob 18 for removing the claw is attached to the tip. 19 is a retaining ring of the winding shaft 7, which has a notch of 20
When the hollow circular hole 21, which has elasticity, is fitted onto the winding shaft 7 between the side wall of the ratchet wheel chamber 5 and the ratchet wheel 11, the winding shaft 7 is supported by the main body 1 so as not to come off, and is stopped. When the shaft 19 is removed from the winding shaft 7, the winding shaft 7
can be easily extracted from the main body 1.

In the tube wringer configured as described above, the fixing piece 12 with the stopper arm 16 attached is housed in the pawl chamber 5 adjacent to the main body 1, and the center hole 13 of the fixing piece 12 is inserted into the main body 1. Bearing holes 4, 4
After inserting the winding shaft 7 from the pawl wheel chamber 5 side into the center hole 13 and the bearing holes 4, 4 and fitting the ratchet wheel 11 attached to the winding shaft 7 into the pawl wheel chamber 5, When the retaining ring 19 is inserted between the ratchet wheel 11 and the side wall of the ratchet wheel chamber 5 and the circular hole 21 thereof is fitted to the winding shaft 7, the ratchet wheel 11 is locked to the retaining ring 19. Therefore, the winding shaft 7 is attached to the main body 1 so as not to come off.
Therefore, align the notch 9 provided on the circumferential surface of the winding shaft 7 with the V-shaped aperture opening 2, insert the bottom tightening part of the tube 8 into the notch 9 through the opening c, and then tighten the knob 10. When it is turned in the direction of the arrow in FIG. 3, the ratchet wheel 11 pushes away the pawl 17, which rotates the winding shaft 7, and the tube 8 is pulled to wrap around the tube 8, forming a V-shaped aperture opening. 2 to squeeze out the contents. However, when the rotation of the knob 10 is stopped, the ratchet wheel 11 engages with the pawl 17 to prevent the winding shaft 7 from rotating in the opposite direction, thereby preventing the winding from returning even with the elastic plastic tube 8.

When the tube 8 becomes empty due to squeezing out the contents and needs to be replaced, pushing the claw release knob 18 in the direction of the arrow in Figure 3 deforms the stopper arm 16 and releases the stopper claw 17. When the tube 8 is pulled in order to remove it from the ratchet wheel 11, the winding shaft 7 rotates in the opposite direction, and the tube 8 that has been wound up is returned. Therefore, when the bottom tightening part of the tube 8 is aligned with the aperture opening 2, if the tube 8 is pulled out laterally from the notch c, the aperture opening 2
Remove only tube 6 from the new tube 8.
By inserting the bottom tightening part into the cutout 9 of the winding shaft 7, the tube 6 can be replaced while the winding shaft 7 is set in the main body 1.

Furthermore, when each part of this wringer becomes dirty and requires cleaning, the retaining ring 19 fitted to the winding shaft 7 between the side wall of the ratchet wheel chamber 5 and the ratchet wheel 11 is removed, and the winding shaft 7 can be easily removed. Bearing holes 4, 4 of main body 1 and fixing piece 1
2, the main body 1, the fixing piece 12 with the stopper arm 16, and the winding shaft 7 can be disassembled into pieces and cleaned individually.

The tube wringer according to the present invention houses a fixed piece with a stop arm in the pawl wheel chamber, aligns the center hole of the fixed piece with the bearing hole of the main body, inserts the take-up shaft from the center hole into the bearing hole, and then rotates the ratchet wheel. The wringer can be easily assembled by placing it in the ratchet wheel chamber and inserting a retaining ring between the ratchet wheel and the side wall. When you insert the bottom tightening part of the tube and turn the knob, the stop pawl and ratchet prevent the tube from reversing, and the tube is wound onto the winding shaft, and the tube is squeezed by the main body's aperture opening, allowing the contents to be extracted. It allows you to squeeze out the material cleanly, and when the tube is empty after squeezing, remove the retaining pawl from the ratchet wheel using the pawl release knob and pull the tube, the take-up shaft rotates in the opposite direction and the tube is removed. When you want to clean the wringer, you can remove the retaining ring from between the side wall of the ratchet chamber and the ratchet wheel, and the wringer can be quickly disassembled to remove each part. Since it can be washed individually, it is easy to manufacture and can be provided to the market at low cost. Winding can be done easily because the tube does not rub against the main body during winding.
Easy to use as the tube can be installed and removed quickly and easily. Since the tube is squeezed by the squeezing opening and wound onto the winding shaft, the contents are squeezed out neatly without remaining and are not wasted. Since the stop pawl and the ratchet wheel prevent the winding shaft from reversing, the winding will not return even if it is an elastic material such as a plastic tube. This has the unique effect that when the wringer becomes dirty, each part can be easily separated and washed individually.
