Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tip dispenser, and more particularly to a tip dispenser having the function of dispensing tips of various diameters.

Today, with the increasing demand for disposable dispensers, various dispensers have been released. However, many of them can only be used for dispensing chips of the same diameter size. However, depending on the place of use or the time of use, for example, an 8-ounce dispenser may be used.
There are also frequent requests for use as a 12 oz dispenser. In order to meet such requirements, a dispenser in which a plurality of tip dispensing elements can be adjusted in distance from each other using a strip member has been announced (for example, see FIG. 1 of Japanese Utility Model Application No. 54-103299). However, this type of dispenser is difficult to adjust and is prone to failure, so it has not been widely put into practical use. Furthermore, as another means, a dispenser for adjusting the radial position of a plurality of leaf springs or a tip support body supporting the top curl of a tip has also been announced (for example, Figs. 2 and 3 of Japanese Utility Model Application Publication No. 54-103299; 57-41888). However, in this type of dispenser, each leaf spring or tip support must be adjusted individually, and therefore, the adjustment work is very time-consuming, and the adjustment cannot be made properly. Therefore, there is a need for a dispenser that can accurately adjust the tip support pieces of all dispensers in the radial direction with a single touch.

The present invention relates to a general-purpose tip dispenser that can dispense tips of various diameters with a very simple means, which enables precise size adjustment with fewer parts, and less failure.

FIG. 1 is a sectional view of the tip dispenser 10 of the present invention. This dispenser 10 includes a cylindrical body 12 accommodating a drop stack, and a part of the cylindrical body 12.
a tip dispensing element 14 fixed to the tip dispensing element 14; a cam member 16 for adjusting the position of the tip dispensing element 14;
Consists of.

The cylindrical body 12 has a cylindrical shape in which a tip stack 22 inserted from one end 20 is housed, and the tips can be sequentially dispensed from a dispensing port 30 at the other end.
One end 20 has a pair of L-shaped notches 24 (second
) is provided in the radial direction, and a protrusion 28 provided on the leg of the lid 26 that closes the one end fits into this notch 24, and when the lid 26 is rotated, the protrusion 28 becomes L-shaped. It rotates within the notch 24 and can prevent the lid 26 from coming off. Inside the cylinder body 12 is a spring 32, and a spring 32 is provided to apply the force of the spring 32 to the tip stack 22, in order to constantly press the tip stack 22 toward the dispensing opening 30 at the other end, especially when the tip is taken out from above. A dish-shaped member 34 for transmitting the information to is housed therein. One end of the spring 32 is supported by the lid 26. The barrel 12, preferably made of synthetic resin, is sized to accommodate tips of various diameters.
The spring 32 and plate member 34 always push tips of various sizes toward the outlet port 30 with a uniform force. Dispensing port 3 of barrel 12 as shown in FIG.
A groove 36 is formed along the end of the side wall near 0 and extends approximately 90 degrees (FIG. 2). Also, the cylindrical body 12
A peephole 38 is provided near the dispensing opening 30 of the dispensing port 30 to see the amount of the dispenser stack inside.

The tip dispensing element 14, in the embodiment shown in FIG.
It consists of and. The strap 40 is provided with a plurality of attachment holes 44 through which the element 14 is secured to the barrel 12 by suitable fasteners 46.
The leg portions 42 may preferably be integrally molded with the band portion 40 from a flexible resin material. However, the leg portion 42
can also be directly fixed to the cylindrical body 12. A tip support portion 48 is provided at the lower end of the leg portion 42 and projects inwardly to engage with the top curl portion of the tip. This support portion 48 has a shape suitable for supporting the top cup stack without damaging the top curl portion of the top cup and for appropriately feeding the bottom cup in sequence. At least three leg-like parts 42 are required, but preferably four.

An inwardly folded portion 39 is provided at the end of the dispensing port 30 of the barrel 12, and an annular cam member 16 is inserted therein.
(Fig. 4) is slidably housed. As shown in FIG. 4, the cam member 16 includes an annular strip 50;
a cam piece 52 protruding radially inward from near the center of the strip 50, preferably integrally therewith;
It consists of In order to slide the cam member 16 on the inner surface of the cylindrical body 12, a notch 5 is formed in a part of the cam piece 52.
4 is provided, and a hole 56 is provided in a part of the strip 50 corresponding thereto, and the groove 3 of the cylinder body 12 is inserted into the hole 56.
A screw 58 is passed through the screw 6, and a split plate 60, a washer 62, and a nut 64 are screwed onto the screw 58. For this purpose, loosen the nut 64 and insert the screw into the groove 3.
6, the cam member 16 can freely move left and right within the cylinder.

The number of cam pieces 52 of the cam member 16 is equal to the number of legs 42. Each cam piece has a cam surface 53 that projects progressively radially inwardly as best seen in FIG. As shown in FIG.
The back sides of 2 are touching. Therefore, as the cam member 16 rotates, the tip support portion 48 at the lower end of the leg portion 42 protrudes inward in the radial direction of the cylindrical body 12 and returns therefrom.

In the present invention, first, when supplying a large-diameter tip, the cam member 16 is rotated in the direction of the arrow 66 in FIG. As a result, the height of the cam surface is minimized and the tip support portion 4 of the tip distribution element 14 is
8 is the most retracted, which makes it possible to supply a large diameter tip. If the size of the feed tip is then reduced, the cam member 16 is rotated in the direction opposite to arrow 66 in FIG. The amount of rotation can be quickly regulated by aligning the tip of the index plate 60 with a scale marked on the edge of the groove 36 of the cylindrical body 12. When the cam member 16 is rotated in the direction opposite to arrow 66, the cam surface height increases and the tip bearing portion 48 of the dispensing element 14 projects radially inwardly, resulting in a reduction in the supply tip size. It is something that can be done.

In this manner, the present invention allows the size of the supply tip to be quickly and safely regulated simply by adjusting the rotation of the screw 58 within the groove 36. Further, the cylindrical body can be arranged so that the tip can be taken out either from below or from above the cylindrical body, as required. The present invention is extremely practical, especially as a commercial dispenser.
