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'' As a conventional example of this type of squeeze container,
-There is a publication No. 41342. As shown in FIG. 4, this publication has a discharge valve element 33 and an intake valve element 34 at the mouth cap 32 of the container body 31, and the body of the container body 31 is squeezed. As shown by the arrow, the liquid inside is pushed out between the back surface of the cap top wall 37 and the umbrella-shaped top wall 38 of the valve body 33 through the liquid flow grooves 36 provided at intervals in the circumferential direction on the internal circumferential wall 35 of the cap 32. The liquid pressure pushes down the umbrella-shaped top wall 38 and therefore the valve stem 39 to open the liquid spout 40, and the liquid is poured to the outside from the spout 40, and the liquid is poured out to create a negative pressure inside the container body 31. When this happens, the intake valve body 34 is displaced downward due to the pressure difference with the atmospheric pressure to open the intake opening 41 and intake an amount of air commensurate with the amount of liquid poured into the container body 31. It is.

"Problems to be Solved by the Invention" According to the above conventional example, in addition to the liquid spout 40, an intake opening 41 is provided in the top wall 37 of the mouth cap 32, which impairs the appearance of the cap. In addition, it is troublesome to attach the intake valve body 34 to the back surface of the top wall 37, and when the peripheral wall of the mouth cap 32 is screwed onto the outer surface of the neck of the container body, the position of the intake opening 41 may be misaligned, etc. There is a risk that the intake valve body may come into contact with the upper end surface of the mouth and neck, resulting in incomplete opening of the valve.

The present invention eliminates the above-mentioned drawbacks and also provides a locking mechanism so that the liquid inside the container will not be poured out unless the locking mechanism is unlocked.

"Means for Solving the Problem" A container body 1 having an elastically compressible body 5 and having a neck part 7 erected, and an outer peripheral part fitted to the upper end of the neck part to form a container body mouth part. 6 is closed, the center part of the top plate part 10 is opened, and the intake pipe 1 is opened from the periphery of the opening.
1, and a leg part 15 is fitted into the intake cylinder 11, and the upper surface of the outer peripheral part of the elastic outward flange 16 protruding from the lower end of the leg is brought into airtight contact with the lower surface of the intake cylinder. to form an intake valve, and an intake groove 1 is formed between the inner surface of the intake cylinder and the outer surface of the leg portion 15.
The intake valve body 3 in which the valve body 2 is installed vertically is fitted with the peripheral wall 19 which hangs down from the periphery of the elastic top wall 17 so as to be rotatable toward the outer surface of the mouth and neck part 7, and the central part of the elastic top wall is opened and the opening periphery is fitted. and a cap 4 which forms a discharge valve by removably bringing the upper end outer peripheral surface of the intake cylinder 11 into close contact with the lower end opening surface of the nozzle 22 that stands up from the cap 4, and pins 13, 13 protruding from the outer surface of the intake cylinder.
are removably engaged by L-shaped locking members 25, 25 hanging from the back surface of the elastic top wall 17 by rotating the cap with respect to the container body, and the palatal member 2
It is characterized in that a liquid outflow hole 14 is formed in the top plate portion 10 of the device.

"Function" In the above configuration, in order to pour out the liquid, first rotate the cap 4 in the direction of the arrow A until the lock piece 24 of the lock member 25 comes off the pin 13 and releases the lock, and then the container body What is necessary is just to squeeze the body part 5 with the hand holding 1. Then, the liquid pressurized by this squeezing is pushed out from the liquid outflow hole 14, and the liquid pressure pushes up the central nozzle 22 through the elastically deformable top wall middle part 23 of the cap 4, and opens the spout 21. Therefore, it is poured out from the spout 21 to the outside. When the inside of the container body 1 becomes negative pressure due to this liquid pouring out, the intake valve body 3 opens due to the pressure difference and the intake tube 11 is opened. Air is drawn into the container body 1 through the vertical grooves 12, 12.

When the liquid is not being poured out, the cap 4 is locked by rotating the cap 4 in the direction of the arrow B and locking the lock piece 24 of the locking member 25 onto the pin 13, so that the liquid will not leak out even if squeezed carelessly. Try not to do that.

``Embodiments'' Embodiments of the present invention will be described below with reference to the accompanying drawings. In each figure, 1 is a squeeze container body, 2 is a palate member attached to the mouth of the container body 1, 3 is an intake valve body attached to the palate member 2, and 4 is a cap.

The squeeze container body 1 is made of soft synthetic resin or the like, and by squeezing the body 5 with a hand, the stored liquid can be pressurized and poured out from the mouth 6. 7 is a mouth and neck portion, and an engagement protrusion 8 is formed on the lower outer periphery of the mouth and neck portion;
Also, the upper part has a small outer diameter.

The palate member 2 has a top plate part 10 installed horizontally at the lower end of a peripheral engagement part 9 having a downward U-shaped cross section, which is engaged so as to clamp the small outer diameter part of the mouth neck of the container body. The central portion of the portion 10 is opened and an intake cylinder 11 is provided upright from the periphery of the opening. This intake cylinder 1
