Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a dispensing container for liquids and provides an improved container for repeated dispensing of metered amounts of liquid.

The invention applies to push pin liquid dispensing containers of the known type having a liquid retaining pin connected to an integral dispensing container by an integral transfer duct, the transfer duct being adapted to push the pin to change the volume. Alternatively, a light pressure can rapidly supply liquid from a pin into a container or suction container.

Such a container is described in European Patent Application No. 79302399.5 (
Publication No. A10010965). Different requirements are found on dispensing containers for different purposes.

In particular, there is a need to provide non-refillable sealed containers, refillable containers, and dispensing containers of adaptable capacity and variety of uses. The invention provides the capacity to adapt to a range of conditions encountered by modification, all using one simple feature in common.

The invention applies to push pin liquid dispensing containers that are integrally molded from a resilient material, having a single spout, a liquid retention pin, a dispensing container, and a liquid transfer duct extending from the bottom of the pin into the container. be done.

According to the invention, a plug that can be inserted through the mouth of the container completely closes the throat of the neck of the pin. Such a simple construction of the pin with the closure plug results in an increased capacity for various uses of the container. This capability is enhanced by a further feature of the present invention, which consists of a container configured with a removable liner that adheres to the interior surface of the container.

U.S. Pat. No. 4,106,7 providing a plug with a hole in the throat between the reservoir and the metering chamber of the dispensing vessel to receive a liquid transfer tube.
It is important to distinguish this invention from previous proposals such as those described in Specification No. 3.

Such a plug only provides support for the tube and is in no way the same as the throat closure plug of this invention. It has also been proposed in the earlier U.S. Pat. No. 4,106,673 to provide a metering chamber by an inner wall separated from an outer wall so as to form a liquid passageway of an extension of a liquid transfer tube between the walls.

Such an inner wall is not the same as a liner such as that formed according to the present invention. The range of capabilities and various purposes afforded to a dispensing container by a closure plug with or without a liner according to the invention is illustrated by the possible features described below.

The plug may be, for example, a removable plug made of a suitable resilient material and configured to fit flexibly or snap-fit into the throat, or a plug that is permanently sealed and cannot be removed without damage. The container can be made into a non-reusable plug. Preferably, the plug is a permanent closure because the containers of the invention are inexpensive and the risk of reuse in hazardous liquids is not worth any cost savings. The removable liner is designed to fit over substantially all of the interior of the dispensing container, somehow altering the function of the t1 container. The dispensing vessel liner can be separated from the plug or removably or non-removably connected to the plug to serve various purposes. A specific example of a liner and its purpose is as follows.

a) The liner is a removable sleeve or cup;
The outlet of the transfer duct is sealed when the dispensing vessel is in place to prevent unwanted transfer of liquid into the dispensing vessel prior to removal of the liner.

The liner is reinstallable to reseal the duct outlet;
Alternatively, the container may be intentionally placed so that it cannot be reused to indicate that it has been opened. If the liner is constructed as a cup, it will serve to dispose of dispensed liquid during use or poured from the container after removal. b) The liner forms an extension of the plug such that the lower part of the dispensing container occupies a known volume, thus changing the volume of the container.

This allows the container to be made in one size and, through the use of an appropriately sized liner, to dispense less liquid than the unlined capacity of the dispensing container. s) The liner and plug are initially connected, such as by making them integrally, the liner assists in inserting the plug into the throat of the container, and the liner can be moved away from the plug at will after insertion, so that the container Cannot be reused.

If made separately, the liner and plug can be connected by a one-way or non-reengageable fitting or adhesive. If made in one piece, the liner and plug can be connected by a frangible section such as a shearable web or tab that breaks when the liner is removed, allowing the plug to be in place on the first use of the container. can be left behind. However, the liner and plug can be permanently connected and the transfer duct opens into the liner and acts as a distribution container so that the container can be refilled when the liner is removed together with the plug. The mouth of the container and the neck of the pin are offset to one side of the top of the container with the injection head in between and form part of or are connected to the container extending towards the opposite side of the container and are connected to the duct. The outlet of the container is directed downwardly through the top of the container.

In such embodiments, the shaped web between the container and the adjacent top of the pin can form a shoulder of the container that acts as a handle. The above-mentioned and other features of the invention are illustrated by way of example in the accompanying drawings.

The containers shown generally in Figures 1, 4, 5 and 6 are made by well known blow molding techniques, in which a tubular parison of thermoplastic material is extruded and then blown to enclose a hollow container, container or duct. The flat and interlocking opposing wall sections are pressed between a pair of molds and excess material is trimmed to the desired overall shape.

As shown in FIG. 1, a duct 2 is integrally formed on the pin 1, and this duct 2 extends from the bottom entrance 3 to the pin 1.
extends upward along the outside of the

The opposing wall portions of the container are flat during molding and are joined in the middle to form web parts 4, 5 forming the duct 2 and the distribution container 6, with an integrally molded outlet forming the upper part of the container. At 7, the duct 2 is open. The dispensing container 6 is formed with a threaded opening 8 for a closure lid 9, and the wall of the dispensing container 6 is provided with graduation marks 1 to indicate the position of a given amount of liquid to be dispensed.
0 can be added as shown.

The material of the container is preferably elastic and transparent or translucent.
A suitable material is polyethylene, with an interior made of copolymers, polypropylene or butadiene-styrene copolymers. It is noted that a neck 11 is formed between the pin 1 and the dispensing container 6 and that the web parts 4, 4 ensure a constant positional relationship between the dispensing container 6, the pin 1 and the duct 2.

The construction of the web section 4, particularly the connection between the integral duct 2 and the web section 5, provides stability and strength to the container despite being made of elastic material. It is growing. The neck 11 is formed with an open throat 12 through which a tubular plow mandrel extends during plow forming to inflate the pin 1 and dispensing container 6 below and above the throat 12. The mandrel has an air hole that supplies air.

After the pin 1 is filled with the liquid to be dispensed, the dispensing container 6
through the wide threaded opening 8 of the plug 13 is inserted to close the open throat 12 and close the open throat 12 when the pin 1 is squeezed to transfer liquid through the duct 2 into the dispensing container 6. Prevent liquid from leaking through. plug 1
3 may be made of a resilient material, such as a soft elastomer, so that the plug 13 can be pushed into and withdrawn from the open throat 12, with the bar 15 being engaged by the hook-shaped withdrawal tool during the latter withdrawal. A crossed groove 14 can be formed.

Further, the plug 13 is made of a hard elastic material, for example, to prevent it from slipping out, and is snapped or tightly fitted into the throat 12 so that it cannot be pulled out even if it is broken.

For this purpose, the plug 13 or the wall of the open throat 12 can be provided with protrusions or grooves for positive engagement. Plug 13 can be sealed using an adhesive or other suitable sealing material.

In the embodiment of the invention shown in FIG. 2, the dispensing vessel 6 has a liner 16 whose wall tapers slightly downwardly and fits snugly inside the dispensing vessel 6 to form a liner 16 for the duct 2. It cuts off Exit 7.

The rim of the liner 16 has a peripheral skirt 17 with internal threads 18.
The internal threads 18 engage external threads 19 around the rim of the dispensing container 6, tensioning the liner 16 to seal against the dispensing container 6 when the liner 16 is screwed on. As shown, the walls of the liner 16 create only a sleeve within the dispensing container 6, but the liner 16 has a closed top 20 so that after removal the liner 16
You can turn it upside down and use it as a cup. Additionally, the bottom of the liner 16 can be closed so that the liner forms a cup in the upright position, and the top of the liner can be provided with a closure, such as a reusable snap-on lid or a disposable foil.

FIG. 3 shows an embodiment of the invention in which the plug 13 is formed with an extension 21 forming a liner which occupies the lower part of the dispensing vessel 6 and considerably reduces the volume of liquid consumed.

The extension 21 of the plug 13 may be tapered or provided with a peripheral lip or bead around the rim to seal the dispensing container 6. In a dispensing container of one standard construction size, the extent of the liner or extension 21 can be made to select the effective capacity and therefore the dispensing container 6.

The integrated plug 13 and extension 21 portions are preferably hollow molded of an elastically deformable plastic material.

Another embodiment of the plug and liner portion is shown in FIG. 4, where the plug 13 is integrally molded with a liner 22 connected to a frangible web portion 23.

The liner 22 has a rim with a threaded skirt 17 and can correspond to the liner 16 of FIG.
The top surface of the plug 13 has a groove 24 for receiving a drive tool, such as a hex key, for inserting the plug and liner when the container is filled.

The rotation of the plug and liner parts when inserted into the dispensing container 6 causes the screws 18, 19 to act to force the plug 13 part downwardly through the open throat 12.

The web 23 is constructed to withstand the torque when the plug 13 is forced through the throat 12 and not cut, and the web 23 is constructed so that the liner 22
leaves the plug 13 in place when it is rotated to unscrew from the dispensing container 6. Also, liner 2
The rim or opening of 2 may be, for example, flat and hexagonal or other polygonal in shape to receive a key or other tool used to insert and remove the liner. The web portion 23 may be constructed as a continuous ring of thin material with tabs of appropriate thickness and angularly spaced intervals to provide the necessary shear strength. In a reusable container, the frangible web section 23 is omitted so that the plug and liner sections can be completely inserted and removed.

In such a case, the liner 22 has an opening 25 for the injection of liquid from the outlet 7 of the duct 2. Instead of being integrally molded, the plug and liner may be attached separately, such as by a push fit, short steep threads, adhesives, fittings, etc., which act as a plug-in rather than a removal plug. Can be joined together.

As shown, the top of the liner 22 has a removable snap closure lid 26, but this is optional.
In the embodiment shown in FIG.
a conical shape inclined towards the injection head 27 between the mouth 8 of the pin 1 and the neck 11 of the pin 1 offset to one side of the upper part of the pin 1 and towards the opposite side of the upper part of the pin 1; Has a cup.

A branch 28 from the top of the distribution vessel 6 opens into an injection head 27 . Such a conical dispensing container has graduation markings 1 consisting of scales with increasing spacing towards the bottom.
0 facilitates accurate injection. As can be seen in FIG. 5, the dispensing container 6, the branch 28 and the web portion 4 form a generally triangular shoulder which acts as a handle for the container, and the dispensing container 6'' is provided with a relatively thick grip. ing.

The upper end of the duct 2 extends to the top of the distribution container 6, so that
Its outlet 7 is directed downwardly through the top of the dispensing vessel 6.

This facilitates accurate dispensing in a tilted position of the dispensing container without affecting the liquid level determined by the outlet 7 of the duct 2. Another embodiment of a pin with a staggered injection head 27 is shown in FIG. There is. In FIG. 6, the dispensing container 6 is provided with a handle grip on the shoulder of the pin 1 and has an outlet 7 from the duct 2.
points downwardly through the top of pin 1.

All of the embodiments shown can be made as liquid-filled containers by a single plow molding, can be closed by inserting a plug to close the open throat, and can be provided with a liner in the dispensing container. It will be understood that it is possible to have no . Features illustrated and described with respect to one embodiment may also be applied to other embodiments.

In particular, the liner is the injection head 27 of the embodiment of FIGS.
The injection head can be placed in the open throat 1.
