Description

[Detailed Description of the Invention] "Industrial Application Field" This invention relates to a dispensing container that is used by squeezing the container and pouring out or spraying the contents.

"Prior art and its problems" This type of dispensing container is equipped with a content outlet pipe that reaches the bottom of the container at the content outlet provided at the mouth of the container, and when the container is squeezed, the content is drawn out from the outlet pipe. There are some that are pushed up through the spout and poured or sprayed. This product has the advantage that the liquid can be poured out while the container is in an upright position.

However, if such a dispensing container is used to contain a liquid containing a substance that decomposes over time and generates gas, such as toilet cleaner or mold remover, such as sodium hypochlorite, storage problems may occur. The internal pressure of the container increases due to the decomposed gas, and when the container is opened to use the liquid inside, the contents will squirt out due to the internal pressure, and the contents may get into the user's eyes or may come into contact with the user's skin, clothing, etc. There was a risk of it getting stuck.

``Purpose of the invention'' This invention was made in view of the above circumstances.
Even if the liquid inside the toilet cleaner is made of a substance such as sodium hypochlorite that decomposes over time and generates gas, it is safe so that the liquid will not spout out unexpectedly when the bottle is opened. The purpose of this invention is to provide a dispensing container that is easy to use.

``Means for solving the problem'' This idea consists of a container body with an air vent and a liquid inlet, and a container body that is movably installed in a position that covers the air vent and liquid inlet. The stopper constitutes a spouting container, and the stopper includes a first blocking portion that blocks communication between the vent port of the container body and the outside air when the plug is in a closed position; The above problem is solved by providing the plug with a second blocking part that blocks communication between the air vent and the outside air when it is in the open position.

"Function" The dispensing container of this invention adopts the above-mentioned configuration, so that when the stopper is moved from the closed position to the position where the spout is opened, the The vent port is once opened to the outside air, and at this time the decomposed gas accumulated inside the container body is released. Therefore, in the case of this dispensing container, the internal pressure of the container reaches atmospheric pressure before the spout for dispensing the contents is opened, so there is no risk of the contents suddenly spewing out when the container is opened. Prevented.

"Example 1" This invention will be described in detail below along with examples.

1 to 3 show a first embodiment of this invention, in which reference numeral 1 is a container body and reference numeral 2 is a stopper.

The container body 1 includes a storage section 3 that stores the liquid content;
It consists of an inner stopper 4. This accommodating portion 3 has a substantially cylindrical shape, and its upper opening 5 has a reduced diameter. The outer peripheral surface of this upper opening 5 has the above-mentioned plug 2.

The stopper 2 includes a cylindrical portion 16 provided with a screw 15 that is screwed into the screw 6 of the container body 1, a top plate 17 that closes the upper opening of the cylindrical portion 16, and a discharge port 18 provided through the top plate 17. A discharge pipe line 19 forming a
It consists of. When the plug 2 is screwed onto the container body 1, the plug 2 is attached to the inner surface of the cylindrical portion 16.
An air vent groove 20 is formed to communicate the inside and outside air. Moreover, a stopper is completely screwed onto the inner surface of the top plate 17 and comes into contact with the upper end surface 8a of the peripheral wall portion 8 of the inner stopper 4 when the stopper is in the closed state as shown in FIG. In contact with the air vent 1 of the inner stopper 4 of the container body 1
A first blocking portion 21 that blocks communication between the air conditioner 2 and the outside air is formed in a ring shape. In addition, the discharge pipe line 1
Reference numeral 9 denotes an approximately L tube consisting of a slide tube 22 fitted into the spout tube 11 of the inner stopper 4, and a discharge tube 23 extending laterally from the top of the slide tube 22 and forming the discharge port 18.
It is shaped like a letter. The slide tube 22 is provided with a protruding sealing rib 24 on its inner surface that slides into airtight contact with the outer surface of the spout tube 11 . Furthermore, a plug protrusion 25 is provided at the top of the slide tube 22 to fit into the spout 10 of the inner stopper 4 to close the spout 10. This plug protrusion 25 is formed when the plug body 2 is raised along the screw 6 of the container body 1.
The blocking portion 21 is formed so as to open the spout 10 after it is separated from the upper end surface 8a of the inner stopper 4.
Further, at the lower end of the slide tube 22, after the plug body 2 is raised and the spout 10 is opened, as shown in FIG. A second blocking portion 26 that blocks communication between ... and the outside air is provided to protrude outward over the entire circumference.

Next, how to use this pouring container will be explained.

First, as shown in FIG. 1, the stopper 2 is sufficiently tightened into the container body 1 to close the dispensing container.
The spout 10 of the container body 1 is sealed by the plug protrusion 25 of the plug body 2, and the communication between the air vent 12 and the outside air is ensured by the first blocking part 21 of the plug body 2 being closed by the upper end surface of the inner plug 4. It is interrupted by contacting 8a. Therefore,
The liquid content, decomposed gas, etc. in the container body 1 will not flow out from the container.

Next, when the stopper 2 is gradually raised along the screw 6 of the container body 1 to open the stopper 2,
First, as shown in FIG. 2, at the beginning of the opening operation of the closure, the first blocking part 21 of the closure 2 separates from the upper end surface 8a of the inner closure 4, and the air vent 12 of the container body 1 opens to the outside air. As a result, the decomposed gas that had been increasing the pressure inside the container body 1 is released, and the inside of the container body 1 becomes atmospheric pressure.

Then, when the stopper 2 is further opened and the dispensing container is opened as shown in FIG.
The stopper protrusion 25 moves away from the spout 10 of the container body 1 and the spout 10 is opened, while the second blocking part 26 of the stopper 2 abuts against the stepped part 14 of the main body 1 and the main body 1
The communication between the air vent 12 and the outside air is cut off. When the spout container is squeezed in this open state, the liquid content rises through the liquid discharge pipe 13 and the spout pipe 11, passes through the discharge pipe line 19, and is discharged from the discharge port 18.

In this pouring container, when the stopper 2 is opened, after the first blocking part 21 of the stopper 2 separates from the upper end surface 8a of the inner stopper 4, the second stopper 26 closes the inner stopper. Until it comes into contact with the stepped portion 14 of the container body 1, the air vent 12 of the container body 1 is in communication with the outside air, which relieves the pressure inside the container body 1. Therefore, before squeezing, the content liquid is removed from the dispensing container. There is no such thing as gushing out.

``Embodiment 4'' Figures 11 to 14 show a fourth embodiment of this invention, and the same components as in each of the embodiments shown in Figures 1 to 10 are designated by the same reference numerals. to simplify the explanation.

In the dispensing container of this example, the stopper 2 is slidably attached to the cap 33 of the container body 1, similar to those shown in FIGS. 7 to 10. The container main body 1 in this example consists of a hollow rectangular parallelepiped-shaped storage section 3 and a cap 33 that closes the upper opening. The cap 33 consists of a rectangular top plate 46 and a side wall 47 that surrounds the rectangular top plate 46 and engages with the housing portion 3 . As shown in FIG. 14, grooves 38, 38 for slidably holding the stopper 2 in the longitudinal direction are formed in the upper edge of the cap 33 along the longitudinal direction. Further, a spout 10 and an air vent 12 are bored in the top plate 46 of the cap 33 on a straight line along the sliding direction of the stopper 2. The areas around the spout 10 and the air vent 12 are raised higher than other parts of the upper surface of the top plate 46.

There is. The second blocking portion 26 closes the spout 10 from the closed state to the open state, as in the case of the third embodiment. These first and second blocking portions 21 and 26 are formed to bulge out from the bottom surface 42 of the plug body 2.

Even in this pouring container, the internal pressure of the container body 1 is balanced with the atmospheric pressure because the vent port 12 communicates with the outside air while the stopper 1 is moved from the closed state to the open state.

Even with the dispensing container of this example, the same effects as those of the embodiment shown in FIGS. 1 to 10 can be obtained.

In the above embodiment, the content liquid outlet pipe 13 is directly inserted into the spout pipe 11 forming the liquid injection port 10, and the content liquid is poured out in liquid form when the container body 1 is squeezed. , not limited to this,
For example, as shown in FIG. 15, the content liquid outlet tube 13 may be inserted into the spouting tube 11 through a spacer 49 having a groove-shaped jet channel 48 on the inner peripheral surface, or as shown in FIG. As shown, a porous body (for example, a sintered polymer,
A porous material such as a mesh or a sponge body) 50 may be provided. Incidentally, in the case of the one shown in FIG. 15 above, when the container body 1 is squeezed, the compressed gas in the upper space of the body 1 is blown out into the spout pipe 11 from the fume passage 48. The contents can be dispensed in a mist form. Also, the first
In the case of the one shown in FIG. 6, if an activator is mixed in the content liquid, the content liquid will be foamed by the gas blown from the spacer 49 when passing through the porous body 50, so that the content liquid will become foamy. It can be poured out in a form.

"Effects of the invention" As explained above, the pouring container of this invention has
a first blocking portion that blocks communication between the vent port of the container body and the outside air when the stopper is in the closed state;
Since the stopper is provided with a second blocking part that blocks communication between the air vent and the outside air when the stopper is in the position to open the spout, the content liquid can be poured out from the spout container. When the stopper is moved from the closed position to the open position in order to remove the stopper, the vent port is in communication with the outside air at the beginning of the movement, and the decomposition gas inside the main body is released to the outside air and the main body There is atmospheric pressure inside. Therefore, when the dispensing container is opened, it becomes a safe container in which the contents do not spill out before being squeezed.
