本考案は、石油ストーブのカートリツジ式燃料
タンク等のような落差式液体補充器に使用される
弁付きキヤツプの改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a cap with a valve used in a drop type liquid replenisher such as a cartridge type fuel tank of an kerosene heater.

る。 Typically, the cap of a drop type liquid replenisher is provided with a valve that opens a flow path when the replenisher is loaded into the combustor body. This valve uses a bent part formed by protruding the center of the outer end surface of the cap as the valve seat, and when the replenisher is loaded into the main body, the external protrusion pushes up the valve to separate it from the valve seat and open the flow path. It is.

出口１ｃ下端に接するまで、この流出が続く。 According to Public Utility Model Publication No. 1983-6830, it has been proposed to protect the valve by locating the outlet of the liquid that is blocked by the valve in a recess at a position lower than the outer end surface of the cap. To explain this conventional example with reference to FIG. 1, a concave portion 1b is formed in the center of the outer end surface 1a of the cap 1, and within this concave portion 1b, the center of the cap is further protruded outward to form a funnel-shaped cap. A cylindrical liquid outlet 1c is provided, and a valve seat 1d is formed at the inner bent portion of the outlet 1c, and the valve 2 is pressed against the valve seat 1d so as to close the flow path. The valve 2 moves up and down inside the valve box 3 while being supported by a guide rod 4, but is always urged downward by a spring 5 inserted into the valve box 3. When the replenisher 6 is loaded into the liquid reservoir 7 of the main body, the liquid reservoir 7
The valve 2 is pushed up by the protrusion 8 fixed therein, the valve passage is opened, and the liquid in the replenisher 6 flows through the liquid passage hole 3a.
This outflow continues until the liquid level in the liquid reservoir 7 touches the lower end of the outlet 1c.

れもないとされている。 According to the description in the above-mentioned publication, in the cap with a valve as shown in FIG. When carrying the replenisher 6 upside down, the valve 2 will not be pushed up and there is no risk of damaging the valve 2 and the outflow port 1c even if the cap part is accidentally brought into contact with the floor etc. It is said that there is no.

本考案は、このようなキヤツプと液体間の跡切れ

のである。 Indeed, according to the above cap, valve 2
Since the outflow port 1c is located within the concave portion 1b on the outer end surface of the cap, it can be avoided from malfunction or damage, but on the other hand, it has the following drawbacks. That is, since the outer end surface 1a of the cap is flat and widely immersed in the liquid level of the liquid reservoir 7, the replenisher 6
When the refiller 6 is removed from the main body for refilling, some of the liquid wets the outer end surface 1a of the cap and is lifted up, spilling onto the floor etc. when transporting the refiller 6 and emitting a foul odor. This has been the subject of complaints because there is a risk of it igniting and causing flames. This is because the contact surface between the valved cap and the liquid is flat and wide, so that the liquid does not drain well.
The present invention improves the shape of the cap in order to improve the separation between the cap and the liquid.

FIG. 2 shows this, and the same reference numerals correspond to the elements and parts in FIG. , Outlet 1c
is from the side or diagonally below (it is unlikely to receive impact from directly below, and is relatively strong against such impact)
Valve seat 1 is easily damaged due to impact from
d is also susceptible to deformation. Moreover, in this case, as pointed out in the description in the above-mentioned publication, when the cap part accidentally comes into contact with the floor or the like, the valve 2 may be pushed up, causing oil leakage.

及び部位に対応する。 The present invention takes into account the respective advantages and disadvantages of the valved caps of Fig. 1 and Fig. 2, protects the valve and outlet from damage, improves the drainage of liquid, and makes it easy to install the valve body. This will be explained below with reference to Fig. 3, which shows one embodiment of the present invention. The same reference numerals in Fig. 3 also correspond to the elements and parts in Fig. 1.

１ｅが防止する。 The center of the outer end surface 1a of the cap 1 is projected outward to form a funnel-shaped or cylindrical outlet 1c. The arcuate tip of the valve 2 should not protrude from the outflow port 1c. A bent portion formed deep inside the outflow port 1c becomes a valve seat 1d of the valve 2. The outer end surface 1a of the cap is formed with a retaining surface for packing 9 on the inner surface by constricting inward approximately horizontally, further concentrically surrounding the outlet 1c, the outer surface 1f stands upright, and the inner surface 1g forms a valve seat 1d. A protruding portion 1e is formed which is inclined from the direction and whose tip has an acute-angled cross section and protrudes in an annular shape. This annular raised portion 1e is formed by installing the outwardly bent lower end 3c of the valve body 3 on the inner surface of the inclined inner surface 1g, and fixing it from the outer surface 1f by rolling it or using a protrusion 1h.
The raised portion 1e also protects the outflow port 1c and the valve seat 1d, and prevents shocks that may be applied to them from the lateral direction.

従つて、補充器６を引き上げるときは、流出口１

で、付着面積が少なく跡切れも良いので、石油ス
トーブを使用中に油が自然に落ちて殆んど残ら
ず、補充器６を引き上げたとき油がこぼれ落ちる
ようなことがない。 The outflow port 1c and the tip of the raised portion 1e have the following positional relationship. That is, the plane L 1 in contact with the tip of the outflow port 1c is the same as or slightly above the plane L 2 in contact with the tip of the raised portion 1e. When the replenisher 6 is correctly loaded, the valve 2 is open, and the liquid has stopped flowing out, the liquid level L 0 in the liquid reservoir 7 is further than the plane L 1 in contact with the outlet 1c. It's below. Therefore, the tip of the raised portion 1e is located slightly above the liquid level. This difference is due to the surface tension of the liquid. Due to the continuity and surface tension of the liquid at the tip of the outlet 1c, the liquid does not come into contact with the protrusion 1e of the cap, but only at the outlet 1c.
Therefore, when pulling up the replenisher 6, the outlet 1
There is a liquid trailing phenomenon only at the tip of c.
The raised portion 1e and other parts of the cap 1 are not wetted by the liquid. When carrying the kerosene stove, even if the oil level fluctuates and oil gets stuck near the protrusion 1e, the tip has an acute cross section, so there is less surface area for it to stick to, and there is no trace of oil. While the stove is in use, the oil falls off naturally and hardly any oil remains, and there is no chance of oil spilling out when the replenisher 6 is pulled up.

ａが嵌入されている。 In Fig. 3, the valve 2 is guided by a cylindrical body 4' instead of the guide rod 4, and an air hole 3b for suppressing the sound of air bubbles entering the valve as compensation for liquid outflow. A hole is provided at the tip of the box 3. The valve 2 has a valve seat 1 as in FIGS. 1 and 2.
A suitable ring-shaped elastic body 2 is placed in the part that comes into direct pressure contact with d.
a is inserted.

危険を防止できる。 As described above, the cap with a valve of the present invention allows the outlet 1c to protrude so that the arcuate tip of the valve 2 does not protrude to the outside, and at the same time extends the outer surface 1f around the outlet 1c.
is upright, and the inner surface 1g is inclined from the direction of the valve seat 1d, and the tip has an acute-angled cross section and protrudes in an annular shape.
The tip of the outlet 1c is at the same level as the tip of the raised part 1e, or has a shape that protrudes upward by a slight difference, and a valve seat is provided at the inner bent part of the outlet 1c. 1d, it is difficult to damage the outlet 1c and the valve seat 1d, and the valve 2 will not open due to contact with the floor etc. Moreover, when the replenisher 6 is lifted from the liquid surface, there will be no trace of liquid. It is sharp and therefore prevents the risk of liquid dripping onto the floor or the like, emitting bad odors, or igniting and causing flames.

を完全になくすることができる。 In addition, the lower end 3c of the valve box 3 is installed and fixed on the inclined inner surface 1g of the raised portion 1e, so it has good stability. Since there is no need to spot weld the plates together, installation is easy and oil leakage accidents can be completely eliminated.
