dispenser

Abstract

The present invention provides a pump dispenser that is simple in structure and easy to use. [Solution] The dispenser of the present invention is a dispenser comprising a container 1 for containing liquid, a pump 3, and a nozzle 4, and a stretchable membrane 2 is attached to the bottom of the container, close to the bottom, so as to divide the space inside the container.When the pump is attached to the container, the stretchable membrane is pushed down by the tip of the pump, stretching it into an inverted cone shape, which causes the liquid contained in the container to gather in the stretchable membrane, making it easier for the pump to suck up the liquid.

Description

[Technical Field]

[0001] The present invention relates to a dispenser that dispenses a fixed amount of liquid such as shampoo or detergent contained in a container. [Background technology]

[0002] With conventional dispensers, when the amount of liquid stored in the container becomes low, it becomes difficult for the liquid to be ejected from the dispenser nozzle, or the amount of liquid ejected decreases. Therefore, in order to use the remaining liquid, it was necessary to remove the pump from the dispenser (container), turn the dispenser (container) upside down, and remove the remaining liquid.

[0003] Therefore, for example, Patent Document 1 discloses a pump dispenser comprising a pump cylinder, a sealing member dividing the pump cylinder into an upper space and a lower space, a tubular stem for moving the sealing member up and down, and a spring for pushing the stem upward, wherein a liquid agent in a pouch moves to the lower space by pushing the stem upward, and a liquid agent in the lower space moves into the stem by pushing the stem downward, the pump dispenser comprising an outside air introduction path that connects the outside air in the liquid agent storage container with the inside of the pouch via the upper space, and a valve provided in the outside air introduction path between the upper space and the outside air, the valve opening at least when the stem is pushed down and closing at least when the stem is pushed up and at its top dead center, and a second valve provided between the upper space in the outside air introduction path and the inside of the pouch, the second valve opening at least when the stem is pushed up and closing when the stem is at its top dead center. According to this, when liquid is dispensed by pumping, the pump pushes out air on the upward (return) stroke and injects it into the pouch, reducing the generation of negative pressure and dents in the pouch. This prevents the films on the front and back of the pouch from coming into close contact and adhering, making it easier for the liquid to move to the bottom, minimizing the amount of residual liquid that cannot be sucked up. In addition, when the upward stroke ends, the valve in the pipe that injects outside air into the pouch closes, so that neither air nor liquid will leak out even if the pouch is tipped over, and splashes of water will also be prevented from entering the pouch.

[0004] However, unlike the pump cylinder of Patent Document 1, there is no known dispenser that can be realized with a simple structure. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent Publication No. 6074091 Summary of the Invention [Problem to be solved by the invention]

[0006] Therefore, an object of the present invention is to provide a dispenser that can be realized with a simple structure. [Means for solving the problem]

[0008] The dispenser according to the present invention comprises a container for storing a liquid, a pump, and a nozzle. 、 The container has a bottom, and an elastic membrane is attached to the inner wall near the bottom so as to separate the space inside the container, and the pump has a length such that its tip contacts the bottom of the container. death The tip is used in a state where it is in contact with the bottom surface of the container. A dispenser , the stretchable membrane is When the container contains liquid, the weight of the liquid causes the container to sink to the bottom of the container, and when the amount of liquid in the container decreases, By the tip of the pump Being held down This causes the material to stretch in an inverted cone shape. the law of nature, housed in a container Ta The liquid The tip of the pump is made of a stretchable membrane that changes shape depending on the weight of the liquid. gathered in liquid It is easy to inhale vinegar It is characterized by the following.

[0010] The aforementioned pump teeth The tip of the membrane has a notch, which makes it easier for the pump to suck in the liquid collected in the stretchable membrane inside the container. [Effects of the Invention]

[0011] In the dispenser of the present invention, the liquid contained in the dispenser container is pressed by the tip of the pump (liquid suction port) and collected at the tip of the pump (liquid suction port) by a stretchable membrane that stretches into an inverted cone shape. Therefore, even if the amount of liquid in the container decreases, the liquid does not become difficult to eject from the dispenser nozzle or the amount of liquid ejected does not decrease, and the liquid can be ejected from the nozzle until the liquid is gone from the dispenser container.

[0013] The dispenser according to this embodiment comprises a container 1 , a pump 3 and a nozzle 4 .

[0014] The container 1 is a general container of various shapes that can hold liquids such as shampoo or detergent, and has a stretchable membrane 2 attached to its bottom near the bottom, as shown in Figure 1.

[0015] The stretchable film 2 may be attached at any position close to the bottom of the container 1, and is preferably attached at a height of about 1 cm to several cm from the bottom of the container 1, for example.

[0016] The stretchable membrane 2 serves to separate the space inside the container 1 into the upper and lower parts, and when no liquid such as shampoo or detergent is contained in the container 1, it is stretched horizontally as shown in Figure 1.

[0017] When the pump 3 and nozzle 4 are attached and there is no liquid such as shampoo or detergent inside the container 1, the stretchable membrane 2 is attached in close contact with the inner wall of the container 1, and when pressed down by the tip of the pump (the liquid intake port), it stretches into an inverted cone shape as shown in Figure 2.

[0018] Since the stretchable membrane 2 is attached in close contact with the inner wall of the container 1, when the container 1 contains a liquid such as shampoo or detergent, the weight of the liquid causes the membrane 2 to sink and stick to the bottom of the container 1, as shown in Figure 3.

[0019] When the container 1 is filled with a liquid such as shampoo or detergent and the pump 3 and nozzle 4 are attached, the weight of the liquid causes the stretchable membrane 2 to sink and stick to the bottom of the container 1, as shown in Figure 4.

[0020] When the amount of liquid in the container 1 decreases from the state shown in Figure 4, the stretchable membrane 2 tries to return to its original state as shown in Figure 5, but is pressed down by the tip of the pump 3 (the liquid intake port), causing it to stretch into an inverted cone shape. In this state, the liquid in the container 1 is collected at the tip of the pump 3 (the liquid intake port). Therefore, even if the amount of liquid in the container 1 decreases, the liquid does not become difficult to eject from the nozzle 4 of the dispenser, and the amount of liquid ejected does not decrease, and the liquid can be ejected from the nozzle 4 until the liquid is gone from the container 1.

[0021] As shown in Figures 6 and 7, the pump 3 has a notch formed at its tip (liquid intake port) to make it easier to suck up the liquid collected in the stretchable membrane 2 when it is stretched into an inverted cone shape. This cutout portion can also be attached as a separate part to the tip (liquid suction port) of the existing pump 3. This makes it easier for the tip of the pump 3 (liquid suction port) to suck in the liquid collected in the stretchable film 2 stretched in an inverted cone shape. [Explanation of symbols]
