Description

Press bottle lid and including its stock solution bottle

Technical Field

The utility model relates to a packing bottle field generally, more particularly, relate to a press the bottle lid and reach the stock solution bottle including this press the bottle lid, it can realize multiple leakage fluid volume.

Background

The pressing bottle cap is widely applied to liquid storage bottles of various liquids, such as shampoo, bath foam, hand sanitizer, liquid detergent, skin cream and the like. When the bottle cap is pressed, the liquid in the bottle can be discharged for use, which is very convenient and popular.

Figure 1 shows a prior art push-on closure design. As shown in fig. 1, the push-on cap is a three-stage design, comprising a reservoir tube 10, a drain tube 20 and a pipette 30, the reservoir tube 10 being fixedly attached to a cap body (not shown) of the cap, which may be, for example, rotatably attached to the mouth of the reservoir. The lower end of the liquid storage pipe 10 is provided with a fixed check valve 12, the upper end is provided with a movable check valve 14, and a spring 16 is arranged between the

check valves

12 and 14. The liquid outlet pipe 20 is inserted into the upper end opening of the liquid storage pipe 10, and the liquid suction pipe 30 is inserted into the lower end opening of the liquid storage pipe 10. Although not shown, the reservoir tube 10 may be fixedly attached to a cap body that may be fixedly mounted to the mouth of the reservoir.

In use, a user may manually press down on outlet conduit 20, such that outlet conduit 20 forces movable check valve 14 to slide downward within reservoir 10. At this time, the valve of the movable check valve 14 is opened, the valve of the fixed check valve 12 is closed, and the liquid stored in the liquid storage pipe 10 is discharged upward through the liquid outlet pipe 20. When the user releases his hand, the movable non-return valve 14 slides upwards inside the reservoir 10 under the elastic force of the spring 16. At this time, the valve of the movable check valve 14 is closed, the valve of the fixed check valve 12 is opened, and the liquid stored in the liquid storage bottle is introduced into the liquid storage tube 10 through the liquid suction tube 30.

However, the above-described push-on cap design has a disadvantage in that it is difficult to control the amount of liquid discharged. As can be seen from fig. 1 and the above description, the amount of liquid discharged depends on the pressing stroke of movable check valve 14, and since a human hand must press movable check valve 14 against the elastic force of spring 16, it is difficult to grasp an appropriate force to press movable check valve 14 to achieve a desired stroke. If the pressing force applied by the hand is slightly small, the check valve 14 cannot be pressed; if the hand pressure is slightly greater, it is easy to press the check valve 14 to its travel limit, thereby expelling a large volume of liquid, which is not suitable for the particular application. For example, in dishwashing, it may be desirable to obtain different amounts of liquid detergent by pressing, depending on the size of the bowl or cooking utensil to be washed.

Accordingly, it is desirable to provide a pressing cap and a liquid storage bottle using the same, which can easily realize desired different liquid discharge amounts.

Detailed Description

Exemplary embodiments of the present invention are described below with reference to the accompanying drawings.

Fig. 2 shows a schematic structural diagram of a pressing bottle cap according to an embodiment of the present invention. As shown in fig. 2, the push cap is a three-stage design including a reservoir 110, a drain 120, and a pipette 130. Although not shown, the reservoir 110 may be fixedly attached to a cap body of a bottle cap, which may be, for example, a conventional cap body, and may be rotatably attached to a bottle mouth of the reservoir, and the outlet tube 120 may extend outwardly through the cap body to discharge the liquid in the reservoir out of the bottle when in use.

As shown in fig. 2, the reservoir pipe 110 is provided at a lower end thereof with a fixed check valve 112, at an upper end thereof with a movable check valve 114, and between the

check valves

112 and 114, an elastic member including at least two springs, which are shown as a spring 116 and a spring 118 in fig. 2, is provided.

A fixed check valve 112 is fixedly coupled to a lower end opening of the reservoir 110, which allows the liquid to flow therethrough in one direction, i.e., upward. When there is a tendency for the liquid to flow downward, the non-return valve 112 closes.

The movable check valve 114 is slidably disposed at an upper opening of the reservoir 110 and is slidable up and down in the reservoir 110, thereby functioning as a piston to press the liquid stored in the reservoir 110 to flow upward through the check valve 114. And when check valve 114 slides upward, the valve closes so that liquid does not flow downward through check valve 114.

Effluent pipe 120 is inserted into the upper end opening of reservoir 110 and is slidable within reservoir 110 so that when effluent pipe 120 is pressed downward, movable check valve 114 is forced to move downward together.

The pipette 130 is inserted into the lower end opening of the reservoir tube 110 and may extend downward, for example, to the bottom of the reservoir bottle, so that almost all of the liquid in the reservoir bottle can be sucked.

The spring 116 and the spring 118 have different spring constants. For example, the spring rate of the spring 116 may be greater than the spring rate of the spring 118, and preferably, the spring rate of the spring 116 is much greater than the spring rate of the spring 118, such as more than twice the spring rate of the spring 118. Preferably, the length of the spring 118 is less than the length of the spring 116. In the embodiment of fig. 2, the

springs

116 and 118 may be connected in series with each other, and an orifice plate 117 for connecting the two springs may be further provided therebetween. Although fig. 2 shows the spring 118 above the spring 116, the spring 118 may also be below the spring 116.

Although not shown, the reservoir tube 110 may be fixedly connected to a cap body that may be fixedly mounted to the mouth of the reservoir.

In use, drain 120 may be pressed with less force if the user desires a smaller amount of liquid to be discharged. At this point, primarily the spring 118 is deformed significantly, while the spring 116 is deformed very little, or hardly. Liquid in reservoir 110 is drained through movable check valve 114 and drain 120. When the user releases his hand, the movable check valve 114 is returned upward by the elastic force of the spring, at which time the movable check valve 114 is closed and the fixed check valve 112 is opened, and the liquid in the bottle is sucked into the reservoir 110 through the pipette 130 and the fixed check valve 112.

On the other hand, when a user desires a larger amount of effluent, then effluent tube 120 may be pressed with a greater force. At this point, spring 118 is compressed to the limit and spring 116 continues to compress to undergo a large deformation so that the bulk of the fluid in reservoir 110 is expelled through movable check valve 114 and outlet tube 120. When the user releases his hand, the movable check valve 114 is returned upward by the elastic force of the spring, at which time the movable check valve 114 is closed and the fixed check valve 112 is opened, and the liquid in the bottle is sucked into the reservoir 110 through the pipette 130 and the fixed check valve 112.

In this embodiment, since the two

springs

116 and 118 having different elastic coefficients are employed, the pressing force required to obtain a large liquid discharge amount is significantly different from the pressing force required to obtain a small liquid discharge amount. Therefore, the user can easily obtain a desired liquid discharge amount by applying different pressing forces. Moreover, the spring 118 with a smaller elastic coefficient has a smaller length, so that a user can press down a smaller stroke with a smaller pressing force to obtain a required small liquid discharge amount, and the operation is convenient and fast. When a large amount of liquid is required, the user can press down a large stroke with a large pressing force.

Fig. 3 shows a schematic structural view of a press bottle cap according to another embodiment of the present invention. The same or similar components as those of the embodiment of fig. 2 are denoted by the same reference numerals, and a repetitive description thereof will be omitted herein, and only the differences will be described.

As shown in fig. 3, the elastic member disposed before fixed check valve 112 and movable check valve 114 includes a spring 116 and a spring 118. Both the spring 116 and the spring 118 are coil springs having different coil diameters so that one spring can be inserted into the coil space of the other spring. The spring 116 and the spring 118 have different spring constants. For example, the spring rate of the spring 116 may be greater than the spring rate of the spring 118, and preferably, the spring rate of the spring 116 is much greater than the spring rate of the spring 118, such as more than twice the spring rate of the spring 118. The length of the spring 118 having a smaller spring constant is greater than the length of the spring 116, but preferably less than 1.5 times the length of the spring 116, and more preferably less than 1.2 times the length of the spring 116.

In use, drain 120 may be pressed with less force if the user desires a smaller amount of liquid to be discharged. At this time, spring 118 is deformed, and spring 116 is short and is not yet pressed by movable check valve 114, and therefore is not deformed. And when movable check valve 114 contacts spring 116, the user may experience a significantly increased resistance. If a user desires a greater amount of fluid to be dispensed, then a greater force may be used to continue to press out drain tube 120, at which point spring 118 and spring 116 are compressed together, thereby achieving a greater amount of fluid to be dispensed.

Therefore, the utility model discloses a press the bottle lid and can realize different liquid capacities, the user that different liquid capacities correspond presses to feel completely different moreover, consequently it is very convenient to use.

Other embodiments of the utility model also provide an use the above-mentioned stock solution bottle of pressing the bottle lid, the aforesaid is pressed the bottle lid and can be installed on the bottleneck of the body of stock solution bottle.
