Toothpick insertion

Technical field

The present invention has made it possible to remove a toothpick which is received by a toothpick protruding from a toothpick outlet of a cap when the storage cylinder for accommodating a toothpick provided movably in the vertical direction is moved downward. Related to toothpick cutting. Landscape technology

Conventional toothpick insertion is performed, for example, as described in U.S. Pat.No. 3,982,660, when a housing cylinder for accommodating a toothpick provided to be vertically movable is moved downward. The toothpick received by the toothpick protrudes from the toothpick outlet of the cap so that it can be removed. A toothpick prong is penetrated through the bottom of the housing cylinder and is supported by the toothpick. Therefore, if the receiving cylinder receives power from the side, it will wobble.

By the way, at the time of removing the toothpick, if the storage cylinder is moved up and down in parallel with the toothpick protruding rod, the operation can be smoothly performed without shaking the storage cylinder. However, a normal toothpick removal operation is not done as carefully as above. When the storage cylinder is moved downward with a lateral force acting on it, the storage cylinder moves in a state inclined with respect to the toothpick, so that friction between the storage cylinder and the in toothpick is generated. As a result, the accommodation cylinder becomes difficult to move smoothly.

ϊ Loaf of paper Under such circumstances, there has been proposed an apparatus adopting a movable support mechanism for preventing the housing cylinder from wobbling when removing the toothpick. For example, in the structure disclosed in Japanese Utility Model Publication No. 49-436667, the movable member is movable by an annular guide portion slidingly contacting the inner surface of the cylinder or by a guide rod inserted into a plurality of guide holes provided in the cylinder 內. A mechanism is configured.

However, the movable support mechanism using the annular guide portion has an annular guide portion attached to the tip of the guide blade, and the guide blade is provided on a push rod fixed to an elastic support piece, and is provided at the bottom of the storage cylinder. It is inserted in the groove formed in. As described above, since the annular guide portion is fixed to the bottom plate of the elastic support piece serving as the base with only the push rod, the operation of taking out the claw branch is performed by the movement of the strong storage cylinder. If you do, you will inevitably be wobbling. If such an operation is repeated for many years, there is a possibility that the fixed portion between the push rod and the bottom plate may be deformed or cracked, and smooth operation may not be performed. In addition, since the annular guide portion slides on the inner surface of the cylinder, the inner surface of the cylinder may be damaged. Furthermore, since the sliding part of the annular guide is exposed to the accommodating part of the toothpick, there are disadvantages such as dirt on the sliding surface being unsanitary due to the toothpick and dirt inside the cylinder being visible from the outside. Was. Then, the tip of the claw lifting branch may be caught in the small gap between the annular guide portion and the inner surface of the cylinder and between the guide blade and the cleaner, and the housing cylinder may not move. The movable support mechanism using the guide rods can stably operate the storage cylinders, but since each guide rod is provided independently, if the guide rods are not properly installed, the operability of the storage cylinders will be improved. Gets worse.

When the capacity of the pickled toothpick is reduced, the upper end of the toothpick will be It is pushed up from below with the appearance of being held at the entrance to the exit. In this process, the toothpick heading toward the outlet was not supported by the toothpick in the other cylinder, so the toothpick was pushed up in a direction away from the outlet, causing the upper end of the toothpick to catch on the inner surface of the cap head.

The removal of the toothpick was done with both hands. That is, the cap was pushed down with one hand, and the toothpick that came out of the outlet was grasped with the other hand. Therefore, if you release your hand from the cap or return the cap to its original position before grasping the toothpick, the toothpick protruding from the outlet will retract and you will have to push down the key again, which is not easy to handle. Was.

On the other hand, in the case of toothpick insertion, the cap is removed from the storage cylinder to supply and clean the toothpick, but at that time, the cap may be accidentally dropped, misplaced, etc. It was happening often.

In addition, when the toothpick was dropped, the cap was disengaged by the impact and the toothpick scattered on the floor and the storage tube became unusable.

As described above, the conventional one did not sufficiently satisfy the problems of the movement of the toothpick in the removal operation and the handling of the toothpick.

A main object of the present invention is to provide a toothpick insert that can remove a toothpick smoothly and reliably.

Another purpose is to pick up the toothpick which can handle the toothpick sanitarily. Is to provide an inset.

Yet another object is to provide a toothpick insert without cap removal due to breakage, loss, or dropping of the cap.

Another object of the present invention is to provide a nail lifter in which operability is improved by stopping lateral vibration of the housing cylinder and at the same time, movement of the slide case due to twisting of the housing cylinder is stopped to improve performance.

It is still another object of the present invention to provide a toothpick insert provided with a cap having improved reliability by increasing the breaking strength of a push plate operated when removing a toothpick.

The cap string 3 is used to prevent the cap from being left behind when the cap 2 is removed from the storage cylinder 1 or to prevent damage or loss due to dropping. belongs to.

As shown in FIG. 10, the cap string 3 is a flat slide 52 provided with a shaft 51 for rotatably connecting the cap 2 and a housing 52. It comprises a slide case 19 attached to the inside of the cylinder and making the slide 52 slidable. The shaft 51 has a head 53 that passes through the shaft hole 38 of the cap. This head 53 has an annular groove 531 for fitting a retaining member 55 for holding the cap 2 in the cap 2 and an annular flange 5111 for engaging an inverted circular shaped washer 60. It is formed. In addition, the upper part 5 2 1 of the slide 52 on the side of the shaft 51 has a member for preventing the toothpick from being caught on the head of the toothpick or the inside of the cap 2 when the toothpick is pushed down in the picking operation. Ring 6 1 is inserted.

The lower end of the slide 52 is provided with a hole 521 for mounting the slide retaining member 62. The slide retaining member 62 is composed of two pieces. One piece 621 is provided with a pair of pins 623 that penetrate the slide hole 521, and the other piece 6222 is provided with the pin.

The slide retaining member 62 is slidably fitted into a slide case 19 described later. FIG. 11 shows another embodiment of Pesher et al. The washer 600 is a washer 600 attached to the shaft 51, an arm 602 extending upward from the washer 601 and a toothpick holding extending from the arm tip in a direction opposite to the diaper 601. And a piece 603. Installation of this washer 600 is the same as that of the washer 600 However, in the mounted state, the toothpick holding piece 63 is located at the toothpick outlet 33 of the keeper 2, and holds the toothpick P (two-dot chain line in FIG. 1) protruding from this outlet.

As shown in FIG. 12, the retaining member 55 is composed of two halves 55a and 55b, and a fitting portion 555 into which the head 53 of the cap string is inserted from the side. There is provided a locking portion 552 which enters the annular shaft 531 of 1 and the head 53.

When attaching the cap string 3 to the cap 2, first, the washer 0 and the ring 61 are inserted into the shaft body 51, and are passed through the annular brim section 5 11 by utilizing its elastic deformation. This shaft body is projected outside from the shaft hole 38 of the cap. The retaining members 55 a and 55 b are fitted into the head 53 protruding from the cap 2 so as to be fitted from the side. When the slide 52 is pulled in this state, the retaining member 55 is fitted into the concave portion 56 of the cap as shown in FIG. Thereafter, the washer 60 is locked to the annular collar portion 5 11. As a result, the cap is rotatably supported about the shaft. In the case of the washer 60, since the outer surface of the inverted conical shape faces the inside of the storage tube 1 when the cap / lace shown in FIG. 1 is mounted, the head of the toothpick does not get caught.

The slide case 19 is formed in a vertically long box shape with one side open, and the upper side of the open side is closed by an upper side wall 92 connected to an end wall 91, and a slide retaining member 62 is formed. When moving to the upper end, prevent it from coming off the open surface. That is, slide 5 2 is slide After passing through the slit hole 93 provided in the end wall 91 of the case, the slide stopper member 62 is fitted to the lower end of the slide, and then the slide case 19 is inserted. This prevents the slide 52 from coming off the slide case. At the edge of the slit hole 93, a slide protection capital 931 extending upward so as to sandwich the of the slide is provided. With such a structure, when the slide 52 is moved in the direction of the arrow in FIG. 9, the slide protector 931 can be bent gently without being locally broken, so that the slide 52 may be damaged. Disappears.

At the lower end of the slide case, a first projection 94 abuts against the lower surface 1a of the storage cylinder 1 (see FIG. 4). A second protruding portion 95 that comes into contact with the upper surface lb (see FIG. 13) and a third protruding portion 96 that is inserted into a notched hole of the housing cylinder receiving member 5 described below are provided. the projecting portion 94, the slide cases fixed part 2 2 0 claw 2 2 1 locked by the pawl 94 0 _c is formed and the second protrusion 9 5, the longitudinal direction of the further slide case After assembling the slide 52 to the slide case 19, as shown in Fig. 10, the open side of the case is placed on the inner side of the storage tube 1 and inserted from the top of the storage case. Take it out of the storage cylinder from 22. Then, move the case in the horizontal direction indicated by the arrow and insert it into the mounting bracket 25 (see Fig. 5). Locking the pawl 94 0 and the claw 2 2 1 slide case fixing portion 2 2 0 of the first projecting portion. At the same time, the lower surface of the first and second protrusions 94, 9 5 holding cylinder la, the upper surface of the groove wall Lock to each lb.

After the cap is assembled, the force acting on the slide case 19 due to the tension of the slide 52 is received by the first protrusions 94, the end walls 91, and the upper side walls 92 provided on both end walls. . The force acting on the slide case from above is received by the second protrusions 95 provided on both side walls. Further, when a force is applied to the lower end of the slide case to move the storage case toward the center of the housing cylinder, the force is received by the engagement of the claw 940 of the first protrusion and the claw 22 of the slide case fixing portion. . Thus, even when a relatively large force acts on the slide case during use, the mounting position of the slide case does not shift or come off, and the function of inserting a toothpick is maintained. On the rear wall of the slide case, a case-side spring receiving portion 97 is provided on the same circumference as the spring receiving portion 26 of the storage tube when the case is assembled.

The positional relationship between the shaft support of the cap 2 to which the shaft of the slide case 19 and the cap string 3 are attached will be described. FIG. 14 shows the cap 2 attached after the toothpick P has been placed in the housing cylinder 1. When the cap 2 is inserted into the housing cylinder 1 at a predetermined position, the slide case and the cap support 35 of the cap 2 and the outer surface of the upper part of the housing cylinder are positioned so that the shaft support portion of the cap is located in a straight line as shown in the figure. Locking ridges 30 are set. Therefore, during the cap insertion operation, the toothpick P gathered near the shaft support is moved sideways on the inclined surface of the washer 60 by the movement of the cap 2 in the direction of the arrow (attachment), and the head of the toothpick is pivoted. It does not impede the insertion of the cap into position when hitting the holding part. In the removal operation of the toothpick, when the storage cylinder is pushed down, if the claw lift received by the claw lifter is leaning on the slide, the storage cylinder is slightly pushed down as shown in Fig. 15. However, the head of the toothpick hits the connecting part between the cap string and the cap and gets caught, which stops the movement of the storage cylinder. In order to solve this problem, a ring 61 is inserted into the upper part of the slide shown in FIG. By the ring 61, the toothpick head is separated from the connecting portion without leaning on the slide. Therefore, removal of the toothpick on the slide side is also performed smoothly.

As shown in FIG. 17, the picked-toe picking member 4 has a plate portion 42 provided with a shaft hole 43 at the center of which a toothpick stick penetrates. The plate portion 42 has a basin-shaped receiving surface 4 a having a downward slope toward the shaft hole 43, and the outer peripheral surface thereof is in contact with the inner surface of the storage cylinder 1. The outer periphery S46 of the plate portion is in contact with the upper end of the rib 21 of the storage cylinder 1. As a result, the toothpick receiving member 4 is positioned.
