Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metering pump container suitable for storing and metering various liquids such as medicines such as mouthwashes, drinks, perfumes, etc.

This type of metering pump container consists of a container body with a mouth and neck standing up from a body that can be squeezed, and a head attached to the mouth and neck. The threaded cylinder, which is composed of a cylinder and a lid that closes the top surface of the measuring cylinder, is threaded onto the outer surface of the mouth and neck from the outer periphery of the bottom wall of the measuring cylinder, and is inserted into the container from the center of the bottom wall. A device is known in which a delivery pipe extending to the bottom side of the body is suspended, and the liquid inside the container body is delivered into the measuring cylinder by squeezing the delivery pipe. (Patent Document 1).

JP2018-34857

The metering pump container of Patent Document 1 delivers a certain amount of liquid from the container body into the measuring cylinder by applying a certain degree of squeezing operation to the body.
However, with this method, the amount of liquid to be delivered varies depending on the amount of force applied to the hand that squeezes the body, making it impossible to measure accurately.
Therefore, when measuring with this container, it is necessary to open the lid in advance and continue to squeeze the body until the liquid level in the measuring cylinder reaches a mark set in the measuring cylinder.
Therefore, additional effort is required to open the lid and to visually check the liquid level within the measuring cylinder, which is troublesome.
In particular, when the amount of liquid used at one time is larger than the amount of liquid obtained in one discharge operation, such as in the case of a mouthwash, it may be necessary to repeat the squeezing. In that case, it becomes more troublesome to visually check the liquid level in the measuring cylinder, which is not convenient to use.
Furthermore, since the lid is opened during the measuring operation, if the container is accidentally tilted, there is a possibility that the liquid being measured will overflow into the surrounding area.

A first object of the present invention is to provide a metering pump container that is easy to use, especially when pumping is repeated.
A second object of the present invention is to provide a metering pump container that allows easy metering with the lid closed.

Further, the inner circumferential wall 28b is suspended along the inner circumferential surface of the cylinder 24 from the ring-shaped top wall 28a as a means for preventing the actuating member 32, which will be described later, from coming off.
Further, a male threaded cylinder 28e stands up from the inner peripheral portion of the ring-shaped top wall 28a.

As shown in FIG. 1, the check valve member 30 is disposed within the lower portion of the cylinder peripheral wall 24a.
This check valve member 30 has a vertically long pedestal part 30a for supporting the bottom surface of a piston guide 34, which will be described later. It is placed on the annular bottom wall.
A plurality of elastic support pieces 30c protrude inward from the lower inner surface of these leg portions 30b, and a first valve plate 30d is provided which is supported by these elastic support pieces 30c. This first valve plate 30d and the first valve seat 24e form a first check valve V1.

As shown in FIG. 1, the operating member 32 includes a piston guide 34, a stem 36, a cylindrical piston 38, a vent opening/closing cylinder 40, and a head portion 42. However, these structures can be omitted as appropriate.
The piston guide 34 includes a bottom plate portion 34a supported by the pedestal portion 30a, an upright wall portion 34b projecting upward from the upper surface of the bottom plate portion 34a, and a wall portion 34b extending from the periphery of the bottom plate portion 34a to the vicinity of the cylinder peripheral wall 24a. It has an extended outward flange-like wall 34c and a seal cylinder portion 34d hanging down from the peripheral end of the outward flange-like wall 34c.
A coil spring C is interposed between the outward flange-shaped wall 34c and the upper end of the leg portion 30b.
Further, as shown in FIG. 1, the upper surface of the outward flange-like wall 34c and the lower end of the inner cylindrical portion 38a of the cylindrical piston 38, which will be described later, form a second check valve V2.
The upright wall portion 34b is formed of a plurality of vertical wall portions (in the illustrated example, a plurality of arcuate wall portions and a radial connecting wall portion) forming a communication path between the second check valve V2 and the stem 36. ing.
Further, in the state shown in FIG. 1, the seal cylinder portion 34d is in liquid-tight contact with the engagement step portion 24f to ensure sealing performance of the pump container.
The stem 36 has an expanding cylindrical portion 36b hanging from the lower end of a vertically long main cylindrical portion 36a. The upright wall portion 34b is fitted into the lower end portion of the main cylinder portion 36a.
The cylindrical piston 38 has an inner cylinder part 38a surrounding the upright wall part 34b, and an outer peripheral part 38b that slides into contact with the inner surface of the cylinder peripheral wall 24a, and these two cylinder parts are connected.
As shown in FIG. 2, the vent opening/closing cylinder 40 has a sliding part 40b at the lower end of a base cylinder part 40a surrounding the stem 36, which slides on the inner surface of the cylinder peripheral wall 24a.
As shown in FIG. 1, in this vent opening/closing cylinder 40, when the operating member 32 is at the lower limit position, a vertical rib 46g of the bottom wall 46 of the measuring cylinder 44, which will be described later, butts against the upper end of the base cylinder part 40a. In this state, the sliding portion 40b is configured to close the ventilation hole h.
The head portion 42 has a measuring tube 44 that communicates with the stem 36, and a female threaded portion 46d is formed on the bottom wall 46 side of the measuring tube 44 and is screwed into the male threaded tube 28e. There is.
By screwing the male threaded cylindrical portion 28e into a female threaded portion 46d, which will be described later, the sealing cylindrical portion 34d is maintained in liquid-tight contact with the engagement step portion 24f.
A more specific structure will be described later.
The structure of the discharge pump can be modified as appropriate. As a preferred embodiment, a modular structure conforming to existing standards can be adopted.

The operation of the configuration described so far will be explained.
In the state shown in FIG. 1, the actuating member 32 is held at the lower limit position by screwing the male threaded tube 28e into the female threaded portion 46d. At this time, the metering pump container has a compact form suitable for distribution and storage as a product.
When using this metering pump container, the head portion 42 is rotated from the state shown in FIG. 1 as shown in FIG. 3(A) to unscrew the female threaded portion 46d from the male threaded tube 28e. Then, the actuating member 32 moves to the upper limit position due to the elastic restoring force of the coil spring C.
Next, as shown in FIG. 3(B), when the actuating member 32 is lowered relative to the pump body 22, the second check valve V2 opens while the first check valve V1 is closed, and the cylinder 24 The liquid inside enters the measuring cylinder 44 via the stem 36 from the second check valve V2.
Next, as the actuating member 32 rises due to the elastic restoring force of the coil spring C, the second check valve V2 closes and the first check valve V1 opens, causing the liquid in the container body 2 to flow into the first check valve V2. It enters the cylinder 24 through the stop valve V1.

In the present invention, first, as shown in FIG. 2, the mounting cap 10 has a guide cylinder section 18 that stands up from the upper end of the mounting cylinder section 12 via a flange-like projection 15.
In the illustrated example, an auxiliary cylinder part 16 extends downward from the lower end of the guide cylinder part 18 . However, these structures can be modified as appropriate.

Further, the head portion 42 is formed of a measuring tube 44, an auxiliary tube 49, and a lid body 50, as shown in FIG.
In the illustrated example, the measuring cylinder, the auxiliary cylinder, and the lid are formed integrally, but this structure can be changed as appropriate, and the measuring cylinder and the lid may be formed separately.

As shown in FIG. 2, the measuring cylinder 44 has a cylinder peripheral wall 48 having a straight cylindrical shape, and a bottom wall 46 that closes the lower surface of the cylinder peripheral wall.
Further, an inward flange-shaped top wall 48d having a flange hole f is attached to the upper inner surface of the cylinder peripheral wall 48.
By closing the flange hole f with the boss portion 52 of the lid body 50, which will be described later, the measuring chamber M surrounded by the cylinder peripheral wall 48, the bottom wall 46, and the inward flange-like top wall 48d becomes an airtight space. is formed.
Although the bottom wall 46 in this embodiment is formed as a separate member (bottom wall member) from the cylinder peripheral wall 48, they may be formed integrally.
Further, although the illustrated measuring tube 44 has a vertically elongated shape, the shape can be changed as appropriate.

As shown in FIG. 2, the bottom wall 46 has a mounting cylindrical portion 46b for attachment to the lower end of the cylindrical peripheral wall 48, and a connecting cylindrical portion 46f for connection to the upper end of the stem 36.
In the illustrated example, the bottom wall 46 has a structure in which an annular upper part 46e protrudes inward from the inner periphery of an annular lower part 46a via an upright cylinder part 46c.
The mounting cylinder part 46b stands up from the outer peripheral part of the annular lower part 46a, and the connecting cylinder part 46f hangs down from the inner peripheral part of the annular upper part 46e.
Further, the internal threaded portion 46d is formed on the inner surface of the upright cylindrical portion 46c. With this configuration, the female screw portion 46d can be formed on the bottom wall 46 without wasting space, resulting in a compact structure.
However, these structures can be modified as appropriate.
In the illustrated example, the lower surface of the annular lower step portion 46a and the upper surface of the ring-shaped top wall 28a are mutually flat horizontal surfaces, and are formed to face each other.
The upper surface of the ring-shaped top wall 28a and the lower surface of the annular lower step part 46a are formed so as to come into contact with each other when the male threaded cylinder 28e is screwed into the female threaded part 46d.
Further, a vertical rib 46g is attached to the upper inner surface. The upper ends of the stem 36 and the vent opening/closing cylinder 40 are abutted against the lower end surface of the vertical rib 46g.

As shown in FIG. 2, the cylinder peripheral wall 48 extends upward from the annular lower step part 46a to be higher than at least the upright cylinder part 46c.
In the illustrated example, a notch 48a is provided around the inner surface of the lower end portion of the cylindrical peripheral wall 48, and this notch 48a is fluid-tightly engaged with the outer peripheral portion of the annular lower step portion 46a.
Further, the mounting cylindrical portion 46b is tightly fitted into the lower inner surface of the cylindrical peripheral wall 48 above the notch 48a.
However, these structures can be modified as appropriate.
Further, the upper end portion of the cylinder peripheral wall 48 is formed into a locking pawl 48b that engages with a lid peripheral wall 50b, which will be described later.
In this embodiment, the cylinder peripheral wall 48 and the rear portions of the lid body 50 are connected by a hinge 48c.
In this specification, for convenience of explanation, the right side of FIG. 1 will be referred to as "rear", the left side will be referred to as "front", and the direction perpendicular to these will be referred to as "left and right".
The hinge in the illustrated example is formed as a thin hinge that is integrally continuous with the cylinder peripheral wall 48 and the lid peripheral wall 50b, which will be described later, but this structure can be modified as appropriate.
In the illustrated example, the upper end surface of the cylindrical peripheral wall 48 is formed into an inclined surface downward from the rear end side toward the front.
This is to facilitate attachment and detachment of the lid peripheral wall 50b, which will be described later, to the upper end of the outer surface of the lid peripheral wall 50b.
A mouth cylinder portion 48e stands up from the upper inner surface of the cylinder peripheral wall 48 via an inward flange-like top wall 48d. This spout can be used as a spout for pouring the contents into an external cup or the like, or as a drinking spout when the contents are a beverage.
As shown in FIG. 4, this mouth tube portion 48e is formed with a cut n that cuts the rear side of the tube wall from the front side downward to the rear.
Further, in the illustrated example, a recess 48f is formed on the front surface of the cylinder peripheral wall 48 so as to be located below a finger rest 50c, which will be described later.
In a more preferred illustrated example, a knurling may be formed on the outer circumferential surface of the cylinder peripheral wall 48 so as to be positioned above the auxiliary cylinder 49 for finger rest during rotational operation.

The auxiliary cylinder 49 is suspended via a flange-shaped protrusion b attached to the upper part of the outer peripheral surface of the measuring cylinder.
The auxiliary cylinder 49 is formed to be close to or in contact with the guide cylinder part 18 and to guide the vertical movement of the head part 42 . However, it is also possible to omit the auxiliary cylinder and the flange-like protrusion, and have a structure in which the measuring cylinder 44 is brought close to or in contact with the guide cylinder part 18.
It should be noted that a locking protrusion p is formed on the upper end side of the auxiliary cylinder 49 to lock the lid in an open state. Note that the position of the locking protrusion can be changed as appropriate.

As shown in FIG. 2, the lid body 50 has a lid peripheral wall 50b extending vertically from the peripheral end of the top plate 50a.
The rear end of the lid peripheral wall 50b is connected to the cylinder peripheral wall 48 by the hinge 48c.
However, instead of such a hinge cap configuration, a screw cap configuration in which the lid circumferential wall 50b is screwed onto the cylinder circumferential wall 48 may be used.
The inner surface of the lower end of the lid circumferential wall 50b is removably fitted to the upper end of the cylinder circumferential wall 48. In the preferred illustrated example, a recessed portion is formed that engages with the locking pawl 48b, thereby resisting the increase in pressure within the metering chamber M and making it possible to maintain the closed state of the lid. In addition, contrary to the illustrated example, the convex portion of the engagement means having an uneven shape may be formed on the lid peripheral wall side, and the concave portion may be formed on the cylinder peripheral wall side.
A finger rest portion 50c is attached to the front portion of the lid peripheral wall 50b.
An engagement recess r that engages with the locking protrusion p when the lid body 50 is opened may be formed on the rear side of the upper surface of the top plate 50a. Thereby, the open state of the lid body 50 is maintained. Note that, unlike the illustrated example, a locking protrusion may be formed on the lid side and an engaging recess may be formed on the auxiliary cylinder side.
A columnar boss portion 52 is provided vertically from the lower surface of the top plate 50a.
This boss portion 52 is tightly fitted into the inner surface of the mouth tube portion 48e. By doing so, the flange hole f of the inward flange-shaped top wall 48d is formed to be more reliably sealed.
In the illustrated example, a die-cut hole i is formed in the center of the top plate 50a, and a stopper cylinder 52a is suspended from the edge of the die-cut hole, and the lower end of this stopper cylinder is closed with a stopper plate 52b. Thus, the boss portion 52 is formed.
Further, the outer peripheral portion of the closing sheet 54 that closes the die-cutting hole i is adhered to the top plate portion around the die-cutting hole.
However, the boss portion 52 may have any structure as long as it can reliably close the flange hole f.
The plug cylinder 52a in the illustrated example has an engagement step 53 extending obliquely from the upper front side to the lower rear side on the outer circumferential surface of the cylinder wall. The side cylinder wall part is made thinner than the upper cylinder wall part.
The engagement step portion 53 is engaged with at least a portion of the upper end surface (in the illustrated example, the front and rear sides of the upper end surface) of the mouth tube portion 48e.

When the top plate 50a of the lid body 50 is pushed down, the contents are delivered from the stem 36 of the discharge pump main body 22 into the measuring tube 44, and a liquid corresponding to the number of times of the pressing operation is measured into the measuring tube 44. Ru.
For example, when a relatively large amount of liquid is used at a time, such as a mouthwash, the discharge pump 20 may be operated multiple times, but in this case, if the number of operations exceeds a certain number in the closed state, , since the pressure in the metering chamber M becomes high, the discharge pump 20 cannot be operated.
Therefore, it is possible to prevent the user from accidentally discharging the content liquid into the measuring chamber M more than the required number of times.
Furthermore, since the flange hole f of the inwardly flange-shaped top wall 48d remains closed by the boss portion 52 during measurement, even if the container is accidentally knocked over, liquid will not spill around.
When the weighing operation is completed, the lid 50 is opened as shown in FIG. If the content is a mouthwash, the mouth can be placed on the mouth tube part 50 and the inside of the oral cavity can be washed as it is.
