Title of the invention: DISPENSER CONTAINER AND METHOD FOR PRODUCING IT FIELD OF INVENTION
[0001] The invention relates generally to a double chamber dispensing container for dispensing two compositions in a mixed state and a method for producing it. CONTEXT
[0002] The statements contained in this section merely provide background information related to this disclosure and may not constitute prior art.
[0003] During the manufacturing and filling of packaging for closures and containers, the containers and closures are typically shipped separately to a product packer, possibly from different suppliers. The containers are filled with product by the packer in an automated or manual filling operation, and then the closures are applied to the containers, again automatically or manually, to complete the packaging. Alternatively, the closures can be applied to the containers when both the containers and closures are supplied to the packer. This alternative reduces inventory at the packer but requires the additional step of removing the closure before filling the container, followed by reapplying the closure after filling.
[0004] Another issue arises when the cap and container are first assembled and then transported for filling. Usually, the cap opening is quite small, as it must be small enough for the consumer to use without wasting too much product. However, if the opening is too small, filling becomes difficult because the filling nozzle is usually larger than the dispensing opening. In this case, the cap typically detaches from the container, making the filling process quite complicated.
[0005] It should be noted that there is still a need for a double-chamber dispensing container for dispensing two compositions in a mixed state and for a method of producing it, in which the product would be poured in an easy and quick manner, and preferably a cap and a container body are assembled in advance and the whole is filled with product in an easy and quick manner without removing the cap, and in this respect, the present invention substantially satisfies this need, and the handling costs at the packer are considerably reduced.

[0036] The following description is purely exemplary and is not intended to limit this disclosure, its application or its uses.
[0037] The following detailed description of the present invention refers to the accompanying drawings, which illustrate specific embodiments in which the present invention can be implemented. These embodiments are described in sufficient detail to enable a person skilled in the art to implement the present invention. It should be understood that various embodiments of the present invention are different from one another, but are not necessarily mutually exclusive.
[0038] With regard to the terms used in the present invention, general terms that are currently and widely used are chosen taking into account the functions of the present invention. However, the meaning of the terms may be modified according to the intention of a person skilled in the art, legal precedent, the emergence of new technology, and the like. Furthermore, in some cases, a term may be chosen at the applicant's discretion. In such cases, the meaning of the term will be described in detail in the corresponding part of the description of the invention. Therefore, the terms used in the present invention should be defined on the basis of the meanings of the terms and the complete descriptions provided herein, and not limited to simply the names of the terms.
[0039] In this disclosure, when a certain part "includes" certain elements, unless explicitly stated otherwise, this means that other elements may be further included, but not excluded.
[0040] A double-chamber dispensing container for dispensing two compositions in a mixed state according to one or more embodiments of the present invention will be described below with reference to Figures 1 to 11.
[0041] Figures 1 to 3 illustrate a double chamber dispensing container 1000 according to an embodiment of the present invention respectively in exploded views and in cross-sectional view.
[0042] As shown in Figures 1 to 3, the double-chamber dispensing container 1000 comprises a substantially tubular container body 1. In one example, the tubular container body 1 is made of an elastically deformable material, for example, high-density polyethylene or polypropylene. In one embodiment, the tubular container body 1 is transparent or translucent, so that the user can easily see the contents inside. In the embodiment of the present invention, the tubular container body 1 includes a closed lower end and an end having an orifice opening 13, into which the body The container defines a chamber. In one embodiment as shown in [Fig.2], the tubular container body 1 includes a ring 11 on one end, and the ring 11 defines an orifice opening 13.
[0043] In one embodiment of the present invention, the double-chamber dispensing container 1000 further comprises a cap 2 for enclosing the orifice opening 13 of the container body 1. The cap 2 is immobilized on the ring 11. In order to apply pressure or an activation force to open the cap 2, the cap 2 may include, on its external surface, a recess 24 to allow a finger to apply force to the cap 2. In addition, in order to facilitate the handling of the container 1000 by a user or during manufacturing or filling, preferably two slots 23 are arranged on the left and right sides of the external surface of the cap 2, which will be discussed below.
[0044] In one embodiment of the present invention, the double-chamber dispensing container 1000 further comprises a partitioning unit 3. The partitioning unit 3 is arranged inside the container body 1 so as to hermetically divide the chamber of the tubular container body 1 into two chambers, namely a first compartment 14 located away from the lower end and a second compartment 15 located near the lower end. The first compartment 14 and the second compartment 15 of [Fig. 2] are imaginary, solely to facilitate understanding the positional relationships for the elements in the container 1000. In one embodiment of the present invention, the first compartment 14 is configured to contain a first composition, and the second compartment 15 is configured to contain a second composition.
[0045] In one embodiment of the present invention, the partitioning unit 3 is disposed inside the tubular container body 1 of the container 1000, hermetically sealing the tubular container body 1 along its peripheral edge. In this way, before the partitioning unit 3 is activated by the user, the two compositions cannot come into contact with each other and are effectively stored hermetically. This makes it possible to store two compositions in separate states, which are relatively unstable when they come into contact with each other, in the same container 1000 for an extended period. In one example, the first composition includes a dye, and the second composition includes a developer.
[0046] Preferably, the partitioning unit 3 is substantially in the form of a disc, for example circular or elliptical, but this shape can of course vary depending on the circumferential shape of the container body 1. In one embodiment of the present invention, the partitioning unit 3 includes a partitioning ring 31 and a partitioning plate 32. In one embodiment, The partition ring 31 and the partition plate 32 are formed in one piece by bi-injection or overmolding or are mechanically assembled under the effect of a force, and the partition plate 32 is configured to be separated from the partition ring 31 under the effect of pressure or a transverse activation force exerted on the container body 1.
[0047] Figure 4 shows an exploded view of a cap 2 of the double-chamber dispensing container 1000 according to an embodiment of the present invention, in which the cap 2 is in the open state, and a nozzle 26 is shown separate from the cap 2. Figure 5 shows a perspective view of a cap 2 of the double-chamber dispensing container 1000 according to an embodiment of the present invention, in which the cap 2 is in the open state. Figure 6 shows a cross-sectional view of the cap 2 of the double-chamber dispensing container 1000 as shown in Figure 5 according to an embodiment of the present invention, in which the cap 2 is in the open state.
[0048] In one embodiment of the present invention, the cap 2 is a hinged cap, and it includes a main body 21 and a cover 22. In one example, the cover 22 is hinged relative to the main body 21 by means of a hinge 25, in particular a film hinge, as shown in [Fig. 6]. In this way, the cap 2 can be easily opened or closed by pivoting the cover 22 relative to the main body 21. In one example, the main body 21 and the cover 22 form a single, monolithic assembly.
[0049] In one embodiment of the present invention, the cap 2 further includes a nozzle 26. In one example, the nozzle 26 is made of a resiliently deformable material, preferably thermoplastic elastomers. As shown in [Fig. 3], in a normal closed state for the dispensing container 1000, the nozzle 26 is hermetically positioned between the main body 21 and the lid 22, thus hermetically sealing the orifice opening 13 of the tubular container body 1. In this way, the contents inside the tubular container body 1 are prevented from leaking out.
[0050] As shown in Figures 4 to 6, the main body 21 includes a filling opening 214 in its center. In one example, around the filling opening 214, the main body 21 includes a first annular wall 211 extending downward from the upper surface 210 of the main body 21. In one example, the first annular wall 211 extends approximately halfway up the main body 21. A lower stop 212 extends radially inward from the lower end of the first annular wall 211 and terminates in a second annular wall 213. The second annular wall 213 extends axially upward from the lower stop 212, and it extends approximately halfway up the first wall annular wall 211. In this way, the first annular wall 211, the lower stop 212, and the second annular wall 213 contain an annular groove 216 to receive the tip 26, which will be discussed below. In one example, the first annular wall 211 includes one or more circumferential recesses 215 on its inner peripheral surface.
[0051] In one embodiment of the present invention, the tip 26 includes a skirt 263 for insertion into the annular groove 216 of the main body 21. On the outer peripheral surface of the skirt 263, one or more circumferential cords 264 are formed which extend radially outwards from the outer peripheral surface of the skirt 263. In one example, the number of circumferential cords 264 is the same as the number of circumferential recesses 215, so that each circumferential cord 264 of the tip 26 is configured to be engaged in each corresponding circumferential recess 215 of the main body 21.
[0052] In one embodiment of the present invention, the nozzle 26 includes a flange 262 extending from the upper end of the skirt 263. The main body 21 includes a stepped portion 217 surrounding the filling opening 214 near the upper surface 210 of the main body 21. When the nozzle 26 is assembled onto the main body 21, the flange 262 rests on the stepped portion 217, so that the upper surface of the nozzle 26 is substantially flush with the upper surface 210 of the main body 21. The stepped portion 217 and the flange 262 also prevent the nozzle 26 from being forced further into the orifice opening 13 of the container body 1.
[0053] In one embodiment of the present invention, the nozzle 26 includes a circumferential boss 261 which extends axially from the upper surface of the flange 262. During dispensing, the circumferential boss 261 will prevent the contents in the tubular container body 1 from flowing onto the upper surface 210 of the main body 21.
[0054] In one embodiment of the present invention, the nozzle 26 includes a dispensing opening 265 passing through its center. In one example, the dispensing opening 265 is hourglass-shaped. In other words, the nozzle 26 further reduces the diameter of the opening that dispenses the contents into the tubular container body 1, compared to the diameter of the filling opening 214. In one example, the nozzle 26 includes a circumferential projection 266 that defines the smaller diameter of the dispensing opening 265.
[0055] In one embodiment of the present invention, the cover 22 includes a cap 221 which closes the distribution opening 265 when the cover 22 is in the closed position illustrated in Figures 1 to 3. In one example, the cap 221 includes a circumferential cord 222 near the free end of the cap 221. The circumferential cord 222 is used to engage with the circumferential projection 266. In another example, the cap 221 fits tightly with the distribution opening 265, so that the cap 221 can sufficiently seal the distribution opening 265. In one embodiment of the present invention, the cap 221 is hollow to increase elasticity, and so that the cap 221 can easily deform to be extracted from the distribution opening 265 when the cover 22 is opened.
[0056] In one embodiment of the present invention, the cover 22 includes a collar 223 extending coaxially with the cap 221. The collar 223 is configured to abut against the upper surface of the nozzle 26 when the cover 22 is in the closed position. In a preferred embodiment of the present invention, the cover 22 further includes numerous reinforcing ribs 224 arranged on the internal and / or external peripheral surfaces of the collar 223, to support the insertion of the nozzle 26 into the main body 21, as explained below.
[0057] Figure 7 shows a cross-sectional view for introducing contents into the double-chamber dispensing container 1000 according to an embodiment of the present invention. Figure 8 shows a perspective view for introducing contents into the double-chamber dispensing container 1000 according to an embodiment of the present invention.
[0058] To perform a filling process, the cap 2 is first tightened onto the ring 11 of the tubular container body 1, in which the lid 22 is in the open position relative to the main body 21. At this stage, the nozzle 26 is attached to the lid 22, as shown in Figures 7 and 8. The nozzle 26 is attached to the lid 22 by inserting the cap 221 into the dispensing opening 265 of the nozzle 26, preferably by engaging the circumferential cord 222 of the lid 22 with the circumferential projection 266 of the nozzle 26. In other words, the cap 2 and the tubular container body 1 are supplied as an assembly or package to a product packer, the assembly or package being transported for filling with the product or contents through the filling opening in the lid 22.
[0059] Next, with the nozzle 26 attached to the lid 22, as shown in [Fig. 8], the assembly or package of the cap 2 and the tubular container body 1 is held in position by a pair of retaining jigs 50 clamping the slots 23 on the outer surface of the cap 2. Subsequently, a filling nozzle 51 will fill the tubular container body 1 with the product or contents. In doing so, a nozzle head 52 will pass through the filling opening 214, which has a larger diameter than the dispensing opening 265, as shown in [Fig. 7]. At this stage, the nozzle 26 remains attached to the lid 22, and the lid 22 remains in the open position.
[0060] Once the tubular container body 1 is filled with the product or contents in a predetermined quantity, the filling is complete. Next, the filling nozzle 51 is removed, and the assembly or package of the cap 2 and the tubular container body 1 is held in position by a pair of retaining jigs 50. The cap is then forced to pivot into the closed position as shown in Figures 1 to 3. Meanwhile, the nozzle 26 is pressed into the main body 21 by pivoting the cover 22 relative to the main body 21 from the open to the closed position. The collar 223 and the reinforcing ribs 224 press against the flange 262 of the nozzle 26, and the circumferential cord 264 of the nozzle 26 is forced to slide into each corresponding circumferential recess 215 of the main body 21.Thus, the cover 22 is now in a closed position relative to the main body 21, and the tip 26 will remain or be permanently held in the main body 21 from that moment on, whether the cover 22 is opened or closed again, because the force required to disengage the tip 26 from the main body 21 is greater than the force required to disengage the tip 26 from the cover. In other words, the frictional force between the circumferential cord 264 of the tip 26 and the circumferential recess 215 of the main body 21 is greater or much greater than the frictional force between the circumferential cord 222 of the cover 22 and the circumferential projection 266 of the tip 26, and thus the tip 26 is permanently held in the main body 21 once it is inserted into the main body 21 for the first time.
[0061] In other words, the cap 2 and the tubular container body 1 are supplied as an assembly or package to a product packer, and the assembly or package is filled with product or contents through the large filling opening in the cap 22. Thus, without removing the cap 2 from the tubular container body 1, the assembly is filled with product easily and quickly, because the filling nozzle, having a larger diameter, can pass through the relatively large filling opening, rather than a rather small dispensing opening. The cap 22 is then closed onto the tubular container body 1 to complete the filled package.
[0062] In one embodiment of the present application, a pair of retaining jigs 50 will clamp the slots 23 on the outer surface of the cap 2 so as to hold the tubular container body 1. In this way, during the filling of the container 1000, there will be little or no pressure or damage to the partitioning unit area. Meanwhile, a filling nozzle 51 will fill the first compartment 14 with the first composition, such as the dye. In one embodiment of the present application, once the first compartment 14 Once filled with the first composition, the retaining templates 50 continue to grip the slots 23, and the lid 22 is closed onto the main body 21 so as to seal the orifice opening 13 and thus seal the first compartment 14. Next, the tubular container body 1 is placed in an inverted position so that the second compartment 15 is at the top and the first compartment 14, which was filled with the first composition, is now at the bottom. Similarly, the second compartment 15 is filled with the second composition, such as the developer. After filling the second compartment 15 with the second composition, the second compartment 15 is closed and sealed by a transverse sealing gasket 12, as schematically shown in [Fig. 2]. In this way, the tubular container body 1 is sealed in both the first compartment 14 and the second compartment 15.
[0063] Figure 9 shows a schematic view of a production process for a double-chamber dispensing container 1000 for dispensing two compositions in a mixed state according to an embodiment of the present invention. First, the tubular container body 1 is a hollow cylinder at the lower end, as shown in Figure 9a. The partitioning unit 3 is inserted into the tubular container body 1 through the open lower end. As shown in Figure 6, a jig is used to support the partitioning unit 3 and the tubular container body 1 in position, and then the partitioning unit 3 is welded to the tubular container body 1, so that the tubular container body 1 is divided into the first compartment near the ring 11 and the second compartment near the lower end.Next, a pair of retaining jigs 50 will clamp the slots 23 on the outer surface of the cap 2 so as to hold the tubular container body 1. In this way, during the filling of the container 1000, there will be little or no pressure or damage to the partitioning unit area. Meanwhile, a filling nozzle 51 will fill the first compartment 14 with the first composition, such as the dye, as schematically shown in Figure 9b.
[0064] After filling the first compartment 14 with the first composition, the retaining templates 50 continue to grip the slots 23, and the lid 22 will be closed onto the main body 21 so as to seal the opening 13 and thus seal the first compartment 14, as schematically shown in Figure 9c. Next, the tubular container body 1 will be placed in an inverted position so that the second compartment 15 is at the top and the first compartment 14, which has been filled with the first composition, is now at the bottom, as shown in Figure 9c. Similarly, the second compartment 15 will be filled with the second composition, such as the developer, by means of another filling nozzle 53, as schematically shown in Figure 9d. After filling the second compartment 15 with In the second composition, the second compartment 15 will be closed and sealed by a transverse sealing gasket 12, as schematically shown in Figure 9e. In this way, the tubular container body 1 is sealed in both the first compartment 14 and the second compartment 15.
[0065] In one embodiment of the present invention, an indicator 16 is formed on an external surface of the substantially tubular container body 1 to assist a user in applying pressure or a transverse activation force to it, as schematically shown in Figure 9e. The indicator 16 may be one or more lines on a circumference of the tubular container body 1 in a position close to that where the partitioning unit 3 is located. In one example, the indicator 16 may be a raised feature on a circumference of the tubular container body 1. The indicator 16 may provide the user with a visual or tactile sensation.
[0066] During use, the user can first press or squeeze the body of the tubular container 1, preferably using the indicator 16, to press the partition unit 3 and separate the partition plate 32 from the partition ring 31. After the partition plate 32 is separated from the partition ring 31, the compositions in the first compartment 14 and the second compartment 15 can pass through the partition unit 3. The user can then shake the container 1000 to evenly mix the first and second compositions. Once the first and second compositions are sufficiently mixed, the user can squeeze the body of the tubular container 1 in the normal manner, and the mixed compositions are then extruded for use.
[0067] Figure 10 shows an exploded view of the double-chamber dispensing container 1000' according to another embodiment of the present invention, wherein the container 1000' includes a screw-on cap 120. In one example, the cap 120 includes a cap body 121 for capping the container body, and there is a stopper 124 for sealing the cap 120. In one example, the cap body 121 includes a dispensing opening at the top for dispensing the contents during use. In one example, the cap body 121 includes a collar 122 for receiving the stopper 124 by snap-fit assembly, for example. In one example, the stopper 124 includes a circumferential cord 123. The circumferential cord 123 is used to be pushed into the collar 122 so as to seal the dispensing container 1000'.
[0068] In one example, the double-chamber dispensing container 1000' comprises a substantially tubular container body 110. In this embodiment, the double-chamber dispensing container 1000' is clamped onto the container body 110, and not onto the external surface of the cap as shown in Figures 1 to 9. In this embodiment, the container body 110 includes an external thread 111 on its neck. In one embodiment, the container body 110 includes a flat annular flange 112 below the external thread 111 in a plane normal to a vertical axis of the container body 110. This flange 112 is adapted to secure the cap 120 to the container body 110 via the cap 120 terminating on the flange 112. In one example, below the flange 112, a pair of parallel guide slots 113 are provided, in which the parallel guide slots 113 are held by a pair of retaining jigs 150, and thus the guide slots 113 can also be referred to as retaining slots to be held during the filling of the container body 110.
[0069] Figure 11 shows a schematic view of a production process for a double-chamber dispensing container 1000' for dispensing two compositions in a mixed state according to another embodiment of the present invention. The process in Figure 11 is essentially the same as that in Figure 9, and the description of the embodiment in Figure 11 will focus primarily on the difference from that in Figure 9. As shown in Figure 11, a pair of retaining jigs 150 will clamp the guide slots 113 of the container body 110 so as to hold the tubular container body 1 in position. In this way, during the filling of the container 1000', there will be little or no pressure or damage to the partitioning unit area. Meanwhile, a filling nozzle 151 will fill the first compartment with the first composition, such as the dye.In one embodiment of the present application, after filling the first compartment with the first composition, the retaining templates 150 continue to grip the guide slots 113, and the cap 120 will be closed on the container body 110 so as to seal the container body 110 and thus seal the first compartment, as shown in Figure 11b.
[0070] Next, the tubular container body 110, together with the cap 120, will be placed in an inverted position so that the second compartment is at the top and the first compartment, which was filled with the first composition, is now at the bottom. Similarly, the second compartment will be filled with the second composition, such as the developer, via the filling nozzle 153. After the second compartment has been filled with the second composition, it will be closed and sealed with a transverse sealing gasket. In this way, the tubular container body 110 is sealed in both the first and second compartments.
[0071] It should be understood that, although the present application relates primarily to a two-chamber dispensing container, the container could be an ordinary container having only one chamber, and the cap in the present application is suitable for various types of container bodies, including container bodies that are too flexible to be clamped without deformation and that are not easy to fill due to a filling or dispensing opening that is too small.
[0072] Thanks to the double chamber dispensing container for dispensing two compositions in a mixed state and a method for producing it according to the present application, the product would be introduced in a simple and quick manner, and preferably a cap and a container body are assembled in advance and the whole is filled with product in a simple and quick manner without removing the cap, the handling costs at the packer are considerably reduced.
