Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a squeeze container in which a container body formed to be elastically deformable is squeezed and liquid in the container is poured out under pressure.

``Prior art'' The upper end surface of the mouth and neck, which stands up from the upper end of the body, is sealed with a highly elastic valve plate made of synthetic rubber, etc., and the valve plate has a cut line cut into it. The valve closes when the separation surfaces come into close contact with each other, and the valve plate expands into a hemispherical shape and elastically deforms due to changes in internal pressure due to elastic compression or restoration of the body, so that both separation surfaces resist elasticity. A liquid container is known in which the valve is opened when the valve is separated, and when the valve is opened, the liquid inside the body is poured out to the outside, and the outside air is sucked into the body (Utility Model Publication No. 49-45952). issue).

``Problems to be solved by the invention'' In the valve of the conventional container described above, the opposing separation surfaces of the cut lines made in the valve plate are brought into close contact with each other due to the elastic force of the valve plate made of highly elastic synthetic rubber against elongation deformation. The valve is closed when the valve is bent, and the valve is opened when the valve plate is stretched and deformed when the valve plate is bent, and the separated surfaces are separated from each other against the elastic force. It is necessary to bring them into perfect contact with each other with the above-mentioned elastic force, and therefore the material of the valve plate has the drawback of being limited to high elasticity, that is, high cost, and the elastic force decreases due to elastic fatigue of the valve plate. Since the separation surfaces do not come into close contact with each other, the durability of the valve plate is low, resulting in the double disadvantage of having to frequently replace the expensive valve plate.

``Means for Solving the Problems'' A container body 1 having an elastically deformable body 4 and a cap-shaped spout 10 fitted in the mouth neck 6 of the container body in the center of a top wall 9. A mounting shaft 13 has a locking protrusion 14 protruding from the bottom of the funnel-shaped peripheral wall with through holes 12 formed here and there in the circumferential direction from the bottom of the outer circumference of the lower end.
A mounting member 15 is provided vertically, and from the back surface of the outer enclosure of this mounting member 15, a presser cylinder 17 with through holes 16 bored here and there in the circumferential direction is provided vertically. A mounting member 2 in which a pair of grooves 19, 19 are formed at appropriate intervals, a thick mounting portion 21 at the center, and a peripheral wall 18 whose peripheral edge is between the grooves 19, 19 at the outer circumference thereof. It has a disc shape with an elastically deformable valve plate 22 in liquid-tight contact with the inner periphery,
The mounting portion 21 is made up of a valve member 3 which is attached to the mounting shaft 13 through the mounting shaft 13 with its upper surface pressed against the presser cylinder 17 .

"Function" In the above configuration, when pouring out the liquid, the body 4 may be squeezed with a hand holding the container body 1. Then, the liquid pressurized by this squeezing reaches the valve member 3.
The valve plate 22 is pushed upward and the peripheral edge thereof is positioned in the upper groove 19 to open the valve as shown in FIG. When the inside of the container body 1 becomes negative pressure due to this liquid pouring, the atmospheric pressure conversely pushes the valve plate 22 downward, and the peripheral edge of the valve plate 22 is pushed down into the lower groove 19 as shown in FIG. 2b.
Since the valve is opened, an amount of air commensurate with the amount of liquid poured out is drawn into the container body 1 from the spouting port 10 through the lower groove 19.

"Example" In the figure, 1 is a container body, 2 is a cap-shaped mounting member attached to the mouth of this container body 1, and 3 is a valve member internally fixed to the back side of this mounting member 2, Each of these parts is molded and manufactured from synthetic resin material.

The container body 1 is made of soft synthetic resin, and its body 4 has elasticity. Therefore, if the body 4 is squeezed with a hand holding the body 4, the stored liquid will be pressurized and the liquid will be transferred to the mouth 5.
It can be poured from. Reference numeral 6 denotes a mouth portion, and a screw thread 7 is formed on the outer circumferential surface of the mouth portion. Reference numeral 8 denotes protrusions for preventing the cap from slipping, which are provided at intervals in the circumferential direction.

The mounting member 2 has an inlet 10 in the center of the top wall 9.
is opened, and the top surface of the circumference of this spout inlet 10 is shaped like a short cylinder 1.
1, and a mounting shaft 13 is suspended from the bottom of a funnel-shaped peripheral wall in which through-holes 12 are perforated here and there in the circumferential direction from the back surface of the periphery of the spouting inlet 10.
A mounting member 15 having a Y-shaped cross section with a locking protrusion 14 protruding from the outer periphery of the lower end is provided vertically, and this mounting member 1
A presser cylinder 17 with through holes 16 bored here and there in the circumferential direction is hung from the back surface of the top wall 9 of the outer casing 5. Further, a peripheral wall 18 whose lower half has an enlarged diameter is provided vertically from the peripheral edge of the top wall 9, and a pair of grooves 19, 19 are provided vertically apart from each other on the inner periphery of the upper half of this peripheral wall 18, and the diameter is enlarged. A screw groove 20 that is screwed into the screw thread 7 is formed on the inner periphery of the lower half. It is also possible to seal the spout 10 with a sheet that can be peeled off during use to prevent dust from entering the valve member 3 from the spout 10 during the distribution process.

The valve member 3 has a thick mounting portion 21 in the center,
It is a disc-shaped valve plate 22 that has an elastically deformable valve plate 22 that gradually becomes thinner toward the periphery.
It is mounted by fitting the mounting shaft 13 into a mounting hole drilled in the mounting portion 21 and sandwiching the mounting portion between the locking protrusion 14 and the holding tube 17, is liquid-tightly inscribed in the inner circumferential surface of the circumferential wall 18 between the grooves 19, 19 to close the valve, and the valve body is bent upward or downward to position its outer circumference in the grooves 19, 19. The valve is designed to open when the valve is opened.

"Effect of the invention" In the valve of the container of the present invention, since the peripheral edge of the elastically deformable valve plate 22 of the valve member 3 is inscribed in the inner surface of the peripheral wall of the mounting member 2, the valve plate can be bent upward or downward. It can be opened and closed by deformation and elastic restoration, and there is no need to bring the cut-off surfaces of the cut lines into close contact with each other due to the elastic force against the elongation of the valve plate, as in the conventional container valves mentioned above, so the material is highly elastic. It is possible to provide an inexpensive container because the valve plate is not limited to a high-cost one, and the valve plate is less likely to loosen due to the reduction in elastic force due to fatigue and require replacement of the valve plate.

Further, the valve of the container according to the present invention has a pair of upper and lower grooves 19, 19 recessed in the upper inner periphery of the peripheral wall 18, and the valve plate 2
Since the valve is opened when the two peripheral edges are located at the upper groove position or the lower groove position, liquid can be poured out through a gap that is wider by the depth of the groove than in the case where the groove is not provided. This allows rapid liquid dispensing.

Furthermore, since the valve plate 22 of the valve member 3 is structured to be able to be moved both upward and downward, a single valve member 3 can perform both liquid pouring and suction, which simplifies the valve structure and reduces the number of parts. It only requires two parts, the mounting member 2 and the valve member 3, and since both of these parts have simple shapes, they can be manufactured at low cost. Furthermore, in this type of container, considerable force is applied to the valve member during liquid pouring and intake, so there are cases in which the valve member comes off, particularly during intake. However, in the present invention, the valve member 3 is
Since the upper and lower surfaces of the thick central mounting portion 21 are sandwiched between the support tube 17 and the locking protrusion 14, the mounting is strong and there is no risk of it coming off.
