Description
- This application claims the benefit of priority under 35 U.S.C. §119 of German
Patent Application DE 10 2013 018 707.9 filed Nov. 8, 2013, the entire contents of which are incorporated herein by reference. - The present invention pertains to a container for the meterable dispensing of a fluid with a first closable reservoir for a first fluid, wherein the first reservoir can be connected with a separate, second, closable reservoir by means of a connection device for establishing a system, and the connection means of the first reservoir and of the second reservoir have an insertion base and an insertion groove each, wherein the insertion base of the first reservoir can be inserted into the insertion groove of the second reservoir and the insertion base of the second reservoir can be inserted into the insertion groove of the first reservoir.
- A container, in which an individual reservoir is provided for receiving an individual fluid, which can be dispensed in a meterable manner by means of a dropper, is known from DE 197 13 951 B4.
- It is disadvantageous that two separate and fully independent containers, which contain each one of the two fluid components, must be used to mix two components of a two-component material. The dispensing of the fluids from the containers must take place one after another or from both containers with two hands in case of simultaneous dispensing. There is a risk now that the two fluids are dispensed at an unfavorable and non-optimal mixing ratio to prepare the two-component material. In addition, the preparation of the necessary mixture is complicated.
- A basic object of the present invention is therefore to provide a container of the type mentioned in the introduction, in which the meterable dispensing of two fluids and/or operation of the container is simplified.
- The basic object of the present invention is accomplished by a container of the type described in the introduction, in which the insertion base of the first reservoir is used as a stop for the insertion base of the second reservoir and the insertion base of the second reservoir is used as a stop for the insertion base of the first reservoir.
- It is advantageous in this case that the first reservoir and the second reservoir form a common container because of the connection device. The container may have the first reservoir and the second reservoir. The especially simultaneous, meterable dispensing of two fluids is considerably simplified hereby. The container makes it possible, in particular, to dispense the fluid associated with the first reservoir and the second reservoir together and/or simultaneously. The second reservoir is preferably intended for a second fluid different from the first fluid. In particular, a preset ratio and/or mixing ratio of the two fluids can be achieved in a simple manner with the container according to the present invention. The connection device is preferably associated directly with the first reservoir and/or the second reservoir. A separate part for connecting the two reservoirs can be eliminated as a result. In particular, the connection device is made in one piece with the first reservoir and/or the second reservoir.
- The container itself is designed, in particular, for the meterable dispensing of a fluid from the first reservoir and/or the second reservoir. The container may be used by hand, especially with one hand, for the meterable dispensing of the fluid or fluids. The meterable dispensing can be preferably performed without auxiliary means, especially without additional auxiliary means and/or devices. The container may be designed for actuation and/or use without a tool. This is preferably achieved by means of suitable droppers and/or an at least partially elastic wall for compressing the container. Operability is simplified hereby.
- The container is preferably used to store and/or dispense a medicinal and/or dental material, especially a dental material. The fluid, preferably the first fluid of the first reservoir and the second fluid of the second reservoir, is designed, in particular, as a flowable dental material. The dental material is especially one of the following materials: A composite, a bonding agent, a bonding material, a cement liquid, a drug, an endodontic rinsing liquid, a dyeing solution, a resin emulsion (especially with a mixing ball), a ceramic liquid, a bleaching agent and/or an etching agent.
- The dental material may be designed as a two-component material. A first component of the two-component material may be the first fluid of the first reservoir and a second component of the two-component material may be the second fluid of the second reservoir. The fluid contains, in particular, one or more of the following ingredients:
- Acetone, ethyl alcohol, water, methyl methacrylate (especially bisphionol-A-(di)methacrylate, decamethylene di-methacrylate, urethane di-methacrylate and/or triethylene glycol-di-methacrylate), methyl ethyl ketone, phosphoric acid, maleic acid, camphorquinone, benzoin methyl ester, acylphosphine oxide, glutaraldehyde, sodium fluoride, polyalkenoate (methacrylated), acrylamidosulfonic acid, functionalized amorphous silicon dioxide, PENTA (dipentaerythritol penacrylate-phosphoric acid monomer), cetylaminohydrofluoride, highly dispersed silicon dioxide, acid acrylate, HEMA 2-hydroxyethyl methacrylate, BHT butylated hydroxyl toluene, pyro-EMA (phosphoric acid modified methacrylate), and ethyl-4-dimethylaminobenzoate.
- The container, the first reservoir and/or the second reservoir preferably has a filling volume of up 10 mL, especially up to 5 mL. The filling volume is especially in the range of 2 mL to 10 mL. The filling volume is especially preferably 2.5 mL, 3 mL, 5 mL, 8 mL or 10 mL. The filling volume relates especially to a filled quantity of fluid. The void volume of the container, the first reservoir and/or the second reservoir is preferably larger than the corresponding filling volume. As a result, the fluid filled in can be shaken up, if desired or necessary, before dispensing or use. In particular, the void volume is larger than the filling volume by 2 mL to 3 mL. The void volume is especially in the range of 6 mL to 7 mL. The void volume of the container, the first reservoir and/or the second reservoir can be obtained from the void volume of the reservoir including the void volume of an outlet, especially a bottle neck-like outlet.
- According to another embodiment, the connection device is designed as an insertion device for establishing a non-positive and/or positive-locking insertion type connection. The insertion device is designed especially as a dovetail device. An insertion device and/or dovetail connection makes it possible to obtain a connection between two partial components, for example, the first reservoir and the second reservoir here, which is easy to prepare and is yet sufficiently reliable. In particular, the first reservoir is a first partial container and the second reservoir is a second partial container. The first reservoir and the second reservoir preferably have insertion device of an identical design each, especially dovetail device. The first reservoir or first partial container and the second reservoir or second partial container can thus have an identical design at least in relation to the connection device, as a result of which manufacture is simplified and/or made easier.
- According to a variant, the first reservoir and/or the second reservoir has a semicircular or hemiellipsoidal cross section. In particular, a semicircular or hemiellipsoidal cross section and/or outer circumference is obtained in a top view of the reservoir or partial container. In particular, the first reservoir and/or the second reservoir has an essentially flat connection side. An insertion device is preferably arranged on the connection side. The insertion device and/or an insertion axis may extend in parallel to a major axis of the hemiellipsoidal cross section to establish the insertion type connection. The connection sides and/or the insertion devices of the first reservoir and second reservoir face each other to establish the connection between the two reservoirs or partial containers with one another to form the container. The two reservoirs connected with one another may form a circular or ellipsoidal circumference for the container.
- The first reservoir and/or the second reservoir preferably has a pressing surface each on a side facing away from the connection side, especially the outer side. The wall material of the first and second reservoirs can be elastically pushed inwardly in the area of the pressing surfaces. The dispensing of a drop is facilitated hereby. The pressing surface preferably extends at least essentially in the longitudinal direction and/or in parallel to an insertion axis to establish the insertion type connection. The pressing surface extends, in particular, at least essentially in parallel to a major axis of a hemiellipsoidal cross section of the first reservoir or of the second reservoir. With the reservoirs connected with one another, the pressing surfaces of the two reservoirs may extend at least essentially in parallel to a main axis of an ellipsoidal cross section of the container. This facilitates an intuitive gripping of the container, during which a person places the thumb on a pressing surface of one of the two reservoirs and at least one finger on a pressing surface of the respective other reservoir. The attempt at compressing the container in the direction of the insertion axis, which is stiffened especially because of the insertion devices, can be avoided hereby.
- The connection device of the first reservoir and of the second reservoir, especially the insertion device, may have an insertion base and an insertion groove each. The insertion base of the first reservoir can preferably be inserted into the insertion groove of the second reservoir and the insertion base of the second reservoir into the insertion groove of the first reservoir. As a result, the insertion type connection can be established in a simple and effective manner by means of connection device and/or insertion devices that have identical design for the first reservoir and the second reservoir. In particular, the insertion base is designed as a dovetail base and the insertion groove as a dovetail groove.
- The insertion base of the first reservoir preferably acts as a stop for the insertion base of the second reservoir. As a result, the path of displacement of the two reservoirs in relation to one another can be limited, and a tactile feedback can be sent to the user to indicate that the connection was successfully established, when establishing the connection between the two reservoirs by means of the stop. In particular, the insertion base of the second reservoir acts as a stop for the insertion base of the first reservoir. The first reservoir and the second reservoir are preferably arranged rotated by 180° about the vertical axis of the first and/or second reservoir to establish the connection by means of the connection device. In particular, a connection of the two reservoirs with one another is established on the basis of a motion of the two reservoirs transversely, especially at right angles to the vertical axis of the reservoir.
- According to another embodiment, the first reservoir and/or the second reservoir has an outlet, which is especially arranged on a top side and/or is bottleneck-like. The fluid of the first reservoir or of the second reservoir can be dispensed by means of the outlet. The first reservoir and/or the second reservoir is preferably made of an elastically deformable material.
- Meterable dispensing of the fluid from the outlet, especially from a dropper connected with the outlet, is simplified hereby. In particular, the dispensed quantity can be controlled by the extent to which the elastically deformable material is pushed in and/or squeezed. The material of the first reservoir and/or of the second reservoir especially preferably possesses barrier properties in respect to the first fluid and/or the second fluid, preferably against permeation of water vapor, methyl acrylate resins, ethyl alcohol and/or solvents, especially acetone. Permeation or penetration through the reservoir is prevented especially because of the barrier properties. The barrier properties of the first reservoir and/or second reservoir preferably prevent permeation of the ingredients of the fluid and/or of the fluid itself. As a result, an undesired reaction of the two components during storage and/or transportation of the reservoirs connected with one another can be avoided, for example, during the storage of two components of a two-component material. The barrier properties of the material are especially such that permeation for oxygen is made possible, especially improved storage stability of the fluid in the first and/or second reservoir.
- The barrier properties can be improved by the first reservoir and the second reservoir being separated from each other in space, especially by means of an air gap, aside from the connection device. In particular, the material layer and/or wall thickness of the first reservoir and/or second reservoir may be made thicker in the area of the connection side facing each other and/or the connection device than in an area of the two reservoirs that directly faces each other.
- To ensure the barrier properties, the first reservoir and/or the second reservoir may be formed from a one-layer or multilayer, especially three-layer material. In case of a three-layer structure, an outer layer and/or an inner layer may be formed from a polyolefin, especially including a bonding agent. Polypropylene or polyethylene may be used as the polyolefin. An intermediate layer arranged between the outer layer and the inner layer may consist of an ethylene-vinyl alcohol copolymer (EVOH).
- The first reservoir and/or the second reservoir may have a one-layer structure consisting of a single material and/or a single material mixture. A multilayer laminate structure can be avoided hereby. The material for the one-layer structure is preferably a mixture of a polyolefin, especially a polypropylene or a polyethylene, with an additive for reinforcing and/or generating the barrier properties. The additive may contain nylon, polyamide and/or EVOH. In particular, the additive contains flakes of nylon, polyamide and/or EVOH. These flakes may at least partially overlie one another within the layer consisting of the material for the one-layer structure. The barrier properties are markedly improved hereby. An additional bonding agent may be eliminated. In particular, the first reservoir and/or the second reservoir can be manufactured each in a single manufacturing step by means of the material for the one-layer structure. Only a single extruder is preferably needed to manufacture the first reservoir and/or the second reservoir.
- According to a variant, a securing device is provided for additionally securing the reservoirs connected with one another and/or the connection device against accidental separation. In particular, a relative motion of the first reservoir relative to the second reservoir is prevented by means of the securing device. The securing device is preferably designed as a cap. An outlet of the first reservoir can be enclosed, covered and/or closed with the cap together with an outlet of the second reservoir. The securing device can thus have at least one dual function, namely, besides the securing of the connection of the two reservoirs with one another, provide an additional, especially openable closing of the outlets of the two reservoirs. The cap can be attached to the outlets especially transversely, preferably at right angles, to an insertion axis, in the longitudinal direction of which the first reservoir and/or the second reservoir can be moved to establish an insertion type connection, to block a displacement of the two reservoirs against one another, especially along the insertion axis. The cap especially meshes at least partially with the outlets. The first reservoir and/or the second reservoir may be manufactured by means of extrusion blow molding, injection blow molding and/or injection molding.
- The cap preferably has a first dropper, which cooperates with the outlet of the first reservoir. In particular, the cap has a second dropper, which cooperates with the outlet of the second reservoir. Meterable dispensing of the fluids is facilitated by means of the droppers. The droppers may be designed such that the drop weight is in the range of 1 mg to 2 mg, and especially around approximately 1.5 mg. When metering 5 drops, the deviation may be in the range of ±0.5 mg to about ±2 mg, and especially around approximately ±1.5 mg.
- The first dropper and the second dropper are preferably coordinated with one another for a preset dispensed quantity and/or for a preset mixing ratio of the fluids from the first reservoir and the second reservoir. The two fluids can thus be dispensed from the two reservoirs in a simple manner and at a desired mixing ratio. The diameters of the first dropper and the second dropper are preferably different from one another and are designed as a function of the viscosity, the rheological and/or physical properties of the fluids associated with the first dropper and the second dropper. In particular, the shape of the first dropper and of the second dropper is adapted as a function of the material properties of the respective associated fluids to be received in the first reservoir and in the second reservoir as well as of the preset mixing ratio of the two fluids or components. The two droppers may have each a cylindrical area, which especially faces the reservoir, and a conical area expanding away from the reservoir starting from the cylindrical area. The internal diameter at the inlet and/or at the outlet of the dropper, the length of the dropper channel and/or of the cylindrical area, and/or the shape of the conical area may be adapted to obtain the preset mixing ratio.
- In particular, the cap has a cover for closing and/or opening the first dropper and the second dropper together. The operation of the container with the two reservoirs is further simplified hereby. The cover and/or the cap preferably has a tamper-evident safety seal. It can be determined by means of the tamper-evident safety seal whether the cover and/or the cap has been hitherto unopened or whether it has already been opened at least once.
- According to another embodiment, a collection area is provided for collecting overflowing first fluid and/or second fluid. The fluid is prevented hereby from flowing down on the container at least for a presettable quantity of overflowing fluid. Undesired contaminations can be avoided hereby. The cap preferably has the collection area especially under the first dropper and the second dropper. The collection area may be designed as a depression and/or in the manner of a basin. The collection area has, in particular, a sink, a groove, a collecting collar and/or a raised edge. The overflowing fluid can thus flow into a basin, a sink and/or a groove in order to be collected there.
- Especially advantageous is a container system with a container according to the present invention, in which a first closable reservoir for a first fluid is connected by means of a connection device with a separate, second closable reservoir for a second fluid for establishing a system. The container system and/or the system is preferably designed such that the first fluid as a first component and the second fluid as a second component can be dispensed simultaneously and at a preset mixing ratio to provide a two-component material.
- The present invention will be explained in more detail below on the basis of the figures. The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of this disclosure.

cap 22 is then pulled over the twooutlets 18. Thecap 22 is locked now with the lockingcollar 20. This prevents thecap 22 from being separated from the tworeservoirs container 12 without destruction. If theopenings 21 are sealed with a foil, the connection pieces 38 puncture the foil when thecap 22 is attached. The connection pieces 38 are in connection with the inner side of theopenings 21 in a fluid-tight manner after attaching thecap 22. As an alternative, the connection pieces 38 may be in contact with an outer side of theopenings 21. - The inner side of the
cap 22 is at least partially in contact with the outer side of theoutlets 18 of the tworeservoirs cap 22 is attached, a relative motion of the tworeservoirs insertion axis 16 is prevented hereby from occurring. Thecap 22 thus acts as a securing device, which prevents an accidental separation of the tworeservoirs - To use the
container 12 and to mix the two fluids from the tworeservoirs cover 23 of thecap 22 is opened. When thecover 23 is opened for the first time, the sealingelement 25 is torn off from thecover 23. A stronger force is necessary for this when thecap 22 is opened for the first time than in case of a subsequent opening. Thecover 23 can be held and opened with a single hand in connection with a one-hand operation. - The
container 12 subsequently brought into an overhead position, in which the fluids flow by themselves into thedroppers reservoirs reservoirs reservoirs droppers reservoirs insertion axis 16 and the respective connection sides 17. This facilitates an intuitive gripping of thecontainer 12, during which a person puts a thumb on apressing surface 36 of the first orsecond reservoir pressing surface 36 of the respective other, first orsecond reservoir - The two fluids may be collected and mixed in a mixing container, which is not shown here more specifically. As an alternative, the two fluids may be dispensed simultaneously into two collection areas and/or trays, which are separated from each other. Mixing or lamination of the two fluids takes place now at the site of application only, for example, directly at a patient within the framework of an application in dentistry. Optimal mixing ratio of the two fluids is automatically achieved during the joint dispensing of an individual drop of the first fluid from the
first dropper 27 and of an individual drop of the second fluid from thesecond dropper 27 due to the individual design of the twodroppers droppers droppers - After dispensing the desired quantity of fluids, the
container 12 is rotated back from the overhead position and placed on the bottom of thecontainer 12 or of the tworeservoirs droppers dropper 27 and/or 28 flows down on the outer side of therespective dropper collection area 32. The fluids are prevented hereby from flowing down on the outer side of thereservoirs - Thus, the
container 12 makes possible the simultaneous, meterable dispensing of two different fluids at a preset ratio, especially mixing ratio, by means of the twoseparate reservoirs - While specific embodiments of the invention have been shown and described in detail to illustrate the application of the principles of the invention, it will be understood that the invention may be embodied otherwise without departing from such principles.
