Description

[Detailed explanation of the idea] This case concerns spray/injection containers.

The present invention aims to provide a convenient, simple, and inexpensive spray/injection container that can be switched between atomization and injection at will.

Hereinafter, the present invention will be explained in detail with reference to illustrated embodiments.

In the figure, 1 is a squeeze type bottle, 2
is a stopper-shaped head attached to the mouth of the bottle, which is suitably made of synthetic resin.

The bottle 1 is provided with a knurled engagement protrusion 12 around the outer edge of a circular mouth 11, and a circular neck 13 below the mouth is formed with a slightly larger diameter and is latched to the outer periphery of the neck. A protrusion 14 is provided around the circumference, and a body 15 below the neck is formed thin and elastically deformable.

The head 2 includes an inner plug body 21 fixedly attached to the mouth portion 11, and rotatably attached to the inner plug body, and
Outer plug body 22 rotatably attached to the neck 13
and a cap 23 removably fitted to the outer plug body.
A pipe 24 is fitted and suspended from the inner stopper body 21 and inserted into the bottle 1.

The inner plug body 21 extends from the periphery of the top wall 211 to the inside and outside 2.
Two peripheral walls 212 and 213 are provided vertically, and these are fitted into the inside and outside of the mouth 11, and a knurled engagement protrusion 214 is provided around the inner edge of the outer peripheral wall 213,
This is non-rotatably engaged with the knurled engagement protrusion 12 at its mouth, and a vertical protrusion stopper 215 is provided protruding from the rear surface of the outer peripheral wall 213. A bulging portion 216 with a circular cross section that swells in steps is provided, and two large and small vertical holes 217, 218 are bored at the center of the bulging portion and behind it, and the upper end of the pipe 24 is inserted into the large vertical hole 217 at the center. It is fitted and hanging down.

The outer plug body 22 has a relatively long peripheral wall 222 hanging from the peripheral edge of the top wall 221, which is loosely fitted into the outer peripheral wall 213 of the inner plug body and the neck 13, and is engaged with the inner edge of the outer peripheral wall. A protrusion 223 is provided around the circumference, and this is rotatably engaged with the locking protrusion 14 on the neck, and a horizontal direction corresponding to the stopper 215 of the outer circumferential wall 213 of the inner plug body is provided on the rear inner surface of the circumferential wall 222. A guide groove 224 is provided, which is loosely fitted into the stopper 215, the center of the top wall 211 is extended upward in two stages, and the extended portion 225 is airtightly connected to the bulged portion 216 of the inner plug body 21. The upper surface of the top portion 226 of the extending portion further protrudes into a spherical shape, and the two inner plug body bulging portions 216 are attached to the inner surface of the top portion 226 in the front-rear direction. A groove 227 communicating with the vertical holes 217 and 218 is provided, and a nozzle 228 is opened in front of the top portion 226 in series with the front end of the groove.
A stepped portion 229 for fitting the cap is provided on the upper surface of the peripheral edge of the cap.

The cap 23 has two inner and outer circumferential walls 232 and 233 hanging from the periphery of a spherical top wall 231.
The inner peripheral wall 232 is removably fitted to the outer plug extension part 225 and the outer peripheral wall 233 to the step 229 of the outer plug top wall 221, and a hinge piece 234 is provided protruding from the rear surface of the outer peripheral wall 233. and attach the hinge piece to the outer plug peripheral wall 2.
It is integrally connected to the rear surface of 22.

Note that the outer plug body 22 and the cap 23 are integrally molded via a hinge piece 234.

The structure is as shown above, and the bottle 1 is used with an appropriate amount of liquid stored in it. When spraying or spraying, remove the cap 23 and squeeze the body 15 of the bottle 1.
As the internal pressure of the bottle 1 increases, the liquid in the bottle 1 rises up the pipe 24 and enters the groove 227 of the outer stopper body 22.
It will be ejected from the nozzle 228.

At this time, as shown in the figure, the groove 2
When the rear end of the bottle 27 is connected to the vertical hole 218 at the rear of the inner stopper body 21, the air in the upper part of the bottle 1 flows from the vertical hole 218 into the groove 227 and is mixed into the ejected liquid. As such, a spray is obtained from the nozzle 228.

Next, as shown by the two-dot chain line in FIG.
When the nozzle 228 is shifted from the position 18, the inflow of air is cut off and only liquid is ejected, and a linear ejection of liquid is obtained from the nozzle 228.

According to the present invention, spraying or liquid jetting can be obtained extremely easily by squeezing the bottle 1, and the switching operation can be performed extremely easily by simply rotating the outer stopper 22 of the head 2, which is extremely convenient in use. be.

In addition, it can be simply constructed by the bottle 1, the head 2 consisting of the inner stopper 21 and the outer stopper 22, and the pipe 24 hanging from the inner stopper 21, and is easy to manufacture.
It can be provided at low cost and is extremely useful in practice.
