Description

Title of the invention: ASSEMBLY FOR PACKAGING AND DISTRIBUTION OF A PRODUCT FIELD OF INVENTION

[0001] The invention generally relates to a packaging and dispensing assembly for a product, and more particularly to a packaging and dispensing assembly for a liquid or viscous product intended to be stored in a manner that is airtight and fluid-tight. The product is a cosmetic, pharmaceutical, or dermo-pharmaceutical product, and is preferably a highly sensitive formula, such as vitamin C with more than 12% or retinol, and any other oxygen-sensitive formula. BACKGROUND

[0002] The statements contained in this section merely provide background information relating to this disclosure and may not constitute prior art.

[0003] An assembly for packaging and dispensing a product is widely used in the cosmetics industry. One type of such an assembly is disclosed by JP2017145011A, for example. JP2017145011A discloses a container configured for dispensing viscous liquid agents, such as shampoo and conditioner, from a flexible bag-shaped container filled with the agents using a pump. This dispensing device can secure a flow path for the liquid and reduce residual amounts of liquid content. The dispensing device comprises a pump, a flexible bag-shaped container, and an outer bottle. The flexible bag-shaped container can be stored inside the outer bottle, and the pump can be connected to both the outer bottle and the flexible bag-shaped container.The flexible bag-shaped container is a sachet-type container in which at least the left and right edges are sealed, which is formed so that the left and right widths, including the sealed edges, are greater than an inside diameter dimension of the outer container before the sachet is inserted into the outer container.

[0004] As shown in [Fig. 9], the flexible, bag-shaped container in JP2017145011A is known as the 1' Doypack® pouch. When filled with liquid, the cross-section bulges to form a large-diameter section with sealing portions on both sides, as shown in the bottom view in [Fig. 9], and the width D2' of the 1' pouch from the left edge to the right edge 14' is quite large, and the outer bottle has a large width D2 so that it is not easily grasped and squeezed to dispense the product via a one-handed pumping function.

[0005] In other words, thanks to the Doypack® pouch, the outer bottle has a long, straight, elliptical shape that is difficult to grasp with one hand. Indeed, the size along one major axis of the elliptical shape is larger, making it difficult for the palm and fingers to completely encircle the outer bottle and apply sufficient pressure to stabilize it.

[0006] It should be noted that, despite various advances in packaging and dispensing assembly designs, there remains an urgent need for a product packaging and dispensing assembly that is easy to grasp and allows for one-handed dispensing while accommodating a sufficient volume of product. Furthermore, the product should preferably be dispensed without air to protect a highly sensitive product. A product packaging and dispensing assembly that meets these challenges can significantly improve the user experience, offering both convenience and extended shelf life. SUMMARY

[0007] An object of the present invention is to provide a product packaging and distribution system and a method for assembling the product packaging and distribution system.

[0008] Thanks to the design of the triangular pyramid pouch sealed in cross joint with the airless nozzle and the airless pump, the packaging and dispensing assembly of a product and the assembly method of the assembly make it possible to obtain a larger internal space for the product, a bottle or a thinner package, which means that it is easy to grasp and dispense the product with one hand, and that less product is left in the pouch and cannot be dispensed.

[0048] The following description is purely exemplary and is not intended to limit this disclosure, its application or its uses.

[0049] 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.

[0050] 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 section of the description of the invention. Therefore, the terms used in the present invention should be defined based on the meanings and complete descriptions provided herein, and not limited to simply the names of the terms.

[0051] In this disclosure, when a certain part "includes" certain elements, unless explicitly stated otherwise, this means that other elements may in addition be included, but not excluded.

[0052] A packaging and dispensing assembly for a product according to one or more embodiments of the present invention will be described below with reference to Figures 1 to 9. The product is in particular a cosmetic, pharmaceutical or dermo-pharmaceutical product, and is preferably a highly sensitive formula, such as VC with more than 12% or retinol and any other oxygen-sensitive formula.

[0053] Fig. 1 is a perspective view of a product packaging and distribution assembly 1000 according to an embodiment of the present invention, in which the assembly 1000 comprises an outer bottle 1 and a cap 9, and in which the cap 9 is closed on a dispensing head.

[0054] As shown in [Fig. 1], the packaging and dispensing assembly 1000 for a product generally has the shape of a right circular cylinder. The outer bottle 1 is roughly in the shape of a right circular cylinder, and the outer bottle 1 may also have another shape for easy gripping, such as a square prism or a regular polygonal cylinder, for example. When using the assembly 1000, a user typically grasps the body of the outer bottle 1. If the outer bottle 1 has a slim external shape, it can be easily grasped with one hand. In one example, the outer bottle 1 is obtained by molding a thermoplastic material such as PET, PP, HDPE, or ABS, for example. The outer bottle 1 is relatively rigid so as to protect the pouch as well as the product it contains, as will be described in more detail below.

[0055] Fig. 2 is an exploded perspective view of the packaging and distribution assembly 1000 for a product according to an embodiment of the present invention.

[0056] As shown in Figures 1-2, in one example, the packaging and dispensing assembly 1000 for a product comprises the outer bottle 1, a sachet 2 containing the product, a spout 3 sealing one end of the sachet 2, a spout collar 4 to hold the spout 3, an airless pump 5, an annular pressing member 6, an actuation member 7, a nozzle 8, and the cap 9. It should be understood that some of the components may be omitted or may be formed as a single piece. In one example, the sachet 2 is made of a plastic film. In another example, bag 2 is made of vacuum metallized PET or vacuum aluminized cast polypropylene (CPP), and preferably, the bag includes one or more of a vacuum metallized layer, an aluminum layer, an AlxO coated layer, a SiOx coated layer, an EVOH layer or a high barrier layer.In one example, the sachet 2 is formed by heat-sealing a film sheet, for example, made of a laminate of multiple thermoplastic resins to which functions such as gas barrier properties have been given. In one embodiment of the present invention, the sachet 2 is formed by heat-sealing an edge 21 along a longitudinal axis X or a longitudinal direction of the external bottle 1, as shown in [Fig. 6]. The direction of the longitudinal axis X or longitudinal direction can also be called the vertical direction. By contrast, the sachet 1', as shown in [Fig. 9], has two edges, i.e., left and right edges. The sachet 2 stores the liquid or viscous product to be dispensed. In one embodiment of the present invention, the spout... The spout 3 is formed on the upper side of the pouch 2. In particular, the upper side of the pouch 2 is sealed onto the spout 3 along a horizontal line 22, as shown in [Fig. 7]. The spout collar 4 can be secured to the spout 3 by means of a threaded fitting, for example. In particular, the spout collar 4 has an internal thread 41, and the spout 3 has an external thread 31 which is configured to engage with the internal thread 41 of the spout collar 4, as shown in [Fig. 4].

[0057] Figure 3 is a longitudinal cross-sectional view of the packaging and dispensing assembly 1000 for a product according to an embodiment of the present invention. Figure 4 is an enlarged cross-sectional view of portion B, as circled in Figure 3, of the packaging and dispensing assembly 1000 for a product according to an embodiment of the present invention.

[0058] The outer bottle 1 preferably has a tubular peripheral wall 11 and a lower wall 12 that is integral with the tubular peripheral wall 11, and the outer bottle 1 is open at the top. Optionally, the outer bottle 1 has a vent 15 on the lower wall 12, so that when the pouch 2 expands, the air in the outer bottle 1 escapes through the vent 15. A thin-walled portion 13 extends from the tubular peripheral wall 11 along the longitudinal axis X of the outer bottle 1, and the thin-walled portion 13 is preferably interrupted in a circumferential direction, so that the thin-walled portion 13 has a certain degree of elasticity along the longitudinal axis X.In one example, the thin-walled portion 13 has one or more annular ribs 14 extending radially outwards from the thin-walled portion 13, so that it can fit together by pressure with an annular rib 42 extending radially inwards from the inner peripheral surface of the lower end of the spout collar 4.

[0059] The airless pump 5 includes a flange 51 near its midpoint, and during assembly, a lower end of the airless pump 5 will pass through the spout 3, and the flange 51 will rest against the upper end of the spout 3. The annular pressing member 6 has an internal thread 63 at one lower end, and the spout collar 4 has an external thread 43 that is configured to engage with the internal thread 63 of the annular pressing member 6. The annular pressing member 6 has a double-walled structure at one upper end, and an annular pressing portion 61 extends radially from the inner wall 62 of the annular pressing member 6. When the annular pressing member 6 is tightened onto the spout collar 4, the annular pressing portion 61 will press the flange 51 of the airless pump 5, so that the airless pump 5 will be fixed in position.The airless pump 5 is a unidirectional dispensing pump 5, so that air outside the assembly 1000 will never be drawn into the bag 2.

[0060] The actuating member 7 is enclosed by the annular pressing member 6 on its peripheral surfaces. The actuating member 7 is formed of a rigid part and slides while being guided within the annular pressing member 6. In one example, the actuating member 7 includes a tubular wall 71 which is guided along the inner wall 62 of the annular pressing member 6. There is an opening 74 arranged on the upper end of the tubular wall 71, and the opening 74 is used to receive a nozzle 8, as explained below.

[0061] In one example, the actuating member 7 includes an actuating portion 72 to allow the product to be dispensed. The actuating portion 72 is movable along a longitudinal axis X of the assembly 1000 by a user who presses on it. In addition, the actuating member 7 includes a bar seat 73 to receive the nozzle 8 inside, as will be explained below. The bar seat 73 is aligned with the opening 74 in a horizontal direction.

[0062] In one example, the nozzle 8 includes a nozzle body 81 for dispensing the product to be applied. The nozzle body 81 is inserted into the opening 74 by means of a press fit, for example. The nozzle body 81 includes a hollow passage 811 and a tapered dispensing opening 812 at the end of the hollow passage 811, which has a reduced diameter compared to that of the hollow passage 811. The tapered dispensing opening 812 allows the product to be dispensed from this opening. The nozzle 8 further includes an air-sealing bar 82 arranged in the hollow passage 811 of the nozzle body 81. When the actuating member 7 is not depressed, the air-sealing bar 82 will abut against and seal the dispensing opening 812, thereby closing the hollow passage 811.Since the nozzle body 81 opens in only one direction, namely in the distribution direction, no air can enter the hollow passage 811 and no potentially already contaminated medium can be re-aspirated.

[0063] Fig. 5 is a perspective view of an air shut-off bar 82 of a nozzle 8 of the assembly 1000 for conditioning and dispensing a product according to an embodiment of the present invention. In the embodiment shown in [Fig. 5], the air shut-off bar 82 includes a rod 821 which is inserted into the hollow passage 811 of the nozzle body 81. The rod 821 has a tapered end 822 to butt against and seal the distribution opening 812 of the nozzle body 81. Near the middle of the air shut-off bar 82 is a flexible sleeve 823. The flexible sleeve 823 has a bowl shape that fits snugly onto the rod 821. The flexible sleeve 823 has a slightly larger diameter in its free state than the diameter of the rod seat 73 of the actuating member 7, so that when the air shut-off bar 82 is inserted into the rod seat 73, The elastic sleeve 823 slides airtight in the bar seat 73. Preferably, the air sealing bar 82 is formed from a single piece.

[0064] In one embodiment, the air sealing bar 82 may be made of POE (polyolefin elastomer), LDPE, HDPE, PP, or other similar materials. The air sealing bar 82 may further include a spring stopper 824 on the end opposite the tapered end 822. The spring stopper 824 is made of an elastic material and acts as a spring. In other words, when the actuation member 7 is pressed, here in response to vertical manual pressure exerted on the actuation portion 72, the product will be pumped by the pump 5 towards a space between the opening 74 and the air shut-off bar 82, and the product will apply pressure to the elastic sleeve 823 to compress the elastic stopper 824, and thus the rod 821 will move away from the dispensing opening 812 of the nozzle body 81, and the product will be dispensed from the dispensing opening 812.When no pressure is exerted on the actuation portion 72, i.e., when the actuation member 7 is no longer depressed, the elastic stopper 824 will automatically rebound, causing the tapered end 822 to again butt against the distribution opening 812 of the nozzle body 81. The distribution opening 812 of the nozzle body 81 is sealed again; that is, the nozzle 8 is in a self-sealing state. In other words, when the nozzle 8 is not in use, the nozzle 8 is in a self-sealing state. In this sense, the nozzle 8 is an airless nozzle.

[0065] In one embodiment of the present invention, the actuating member 7 and the nozzle 8 together constitute a dispensing head. When not in use, the cap 9 will be closed on the dispensing head in order to protect the dispensing head and prevent unintentional dispensing of the product.

[0066] Figure 6 is a perspective view of a sachet 2 and a spout 3 of the packaging and dispensing assembly 1000 for a product according to an embodiment of the present invention. Figure 7 is a top plan view of the sachet 2 and the spout 3 of the packaging and dispensing assembly 1000 for a product on Figure 6 according to an embodiment of the present invention. Figure 8 is a bottom plan view of the sachet 2 and the spout 3 of the packaging and dispensing assembly 1000 for a product on Figure 6 according to an embodiment of the present invention.

[0067] In one embodiment of the present invention, the sachet 2 is formed by heat-sealing an edge 21 along a longitudinal axis X of the outer bottle 1. In one example, the sachet 2 is formed by heat-sealing a film sheet, for example, made of a laminate of multiple thermoplastic resins to which functions such as gas barrier properties have been given. In other words, a film sheet is first sealed along a longer side to forming a longitudinal sealing edge 21, and the film sheet is now formed into a cylinder open at both the top and bottom ends. Next, the top of this cylinder is sealed onto the spout 3 along a horizontal line 22, as shown in Figures 6-7. Then, the bottom of this cylinder is sealed along another horizontal line 23, as shown in Figures 6 and 8. In other words, a pouch 2 is sealed horizontally by a first sealing edge 22 and is sealed by a second sealing edge 23 in a direction different from that of the first sealing edge 22. The sealing process is preferably heat sealing.

[0068] As shown in [Fig. 6], the sachet 2 thus formed has a triangular pyramid shape. In one example, the sachet 2 has triangular surfaces 24, 25, and 26, as shown in [Fig. 6]. On the opposite side, the sachet 2 also has triangular surfaces that are rotationally symmetrical to the triangular surfaces 24, 25, and 26 with respect to a central longitudinal axis of the spout, as shown in Figures 6-8. In this way, the sachet 2 has a triangular pyramid shape sealed in a cross pattern. As shown in Figures 6-8, the first sealing end 22 is essentially perpendicular to the second sealing end 23.In other embodiments, the first sealing end 22 may form an angle with the second sealing end 23, and the angle is preferably between 60 degrees and 120 degrees, preferably between 70 degrees and 110 degrees, more preferably between 80 degrees and 100 degrees, even more preferably between 85 degrees and 95 degrees, and most preferably the angle is 90 degrees. In other words, the triangular pyramid-shaped pouch 2 sealed with a flexible cross appears as if the second sealing end 23 were twisted at an angle to the first sealing end 22, such as being twisted at approximately 90 degrees.

[0069] In one embodiment of the present invention, the first sealing end 22 has substantially the same length as the second sealing end 23. In one example, the length of the first sealing end 22 is slightly greater than the diameter or a diagonal length in a horizontal section of the outer bottle 1. In another example, the length of the second sealing end 23 is slightly greater than the diameter or a diagonal length in a horizontal section of the outer bottle 1. Since the sachet 2 is made of a flexible or pliable material, the first sealing end 22 and the second sealing end 23 can bend to a certain extent, so that the sachet 2 is easily inserted into the outer bottle 1 from its open top.

[0070] Regarding a method of assembling the whole, the bag 2 is first sealed onto the spout 3. Then, the spout 3 is fixed onto the spout collar 4, for example by a threaded fitting. Next, the combination of the sachet 2, the spout 3, and the spout collar 4 is attached to the outer bottle 1 by means of a press fit between one or more annular ribs 14 of the thin-walled portion 13 and the annular rib 42 of the lower end of the spout collar 4. Then, the sachet 2 is blown by a gas compression force to expand it to the tubular peripheral wall 11. The blowing process can be carried out by inserting a blow tube from a gas blowing machine into the spout 2. In other words, the sachet 2 expands to conform to the shape of the outer bottle.In this way, a larger internal space is created for sachet 2, as sachet 2 almost completely fills the internal volume of the outer bottle 1. Thanks to the triangular pyramid shape of the sachet, sealed with a cross, and the material used for the sachet, the sachet will now retain its expanded shape, without returning to its unexpanded state. Next, the product is introduced into sachet 2 from the spout 3. Once the product is introduced, the airless pump 5 is inserted onto the spout 3 and secured by tightening the ring-shaped pressing member 6 onto the spout collar 4. Then, the dispensing head, including the actuation member 7 and the nozzle 8, is arranged onto the ring-shaped pressing member 6 and the airless pump 5, and the assembly process of the product packaging and dispensing unit 1000 is complete.

[0071] In one embodiment of the present invention, using the unidirectional dispensing pump 5, the flexible cross-sealed pyramid pouch 2 gradually contracts, thereby dispensing the product contained therein. Since the first sealing end 22 has a different horizontal orientation than the second sealing end 23, when the product is exhausted, the cross-sealed triangular pyramid pouch 2 retracts with a straight cut, as shown in the image. Consequently, the restitution ratio is minimized, and thus almost all of the product in the pouch 2 is dispensed and used. After numerous tests, it has been demonstrated that more than 95% of the product contained in the pouch can be dispensed.

[0072] Furthermore, thanks to the cross-sealed triangular pyramid pouch 2, a larger internal space is created than with other pouch shapes. For example, the internal space for the cross-sealed triangular pyramid pouch 2 is larger than the internal space for the Doypack® pouch, as shown in [Fig. 9], because the cross-sealed triangular pyramid pouch 2 can almost expand to conform to the shape of the outer bottle 1. In this way, more product can be contained. introduced into the triangular pyramid bag sealed in a cross shape 2 than in a Doypack® bag.

[0073] Thanks to the design of the triangular pyramid pouch sealed in cross joint with the airless nozzle and the airless pump, the packaging and dispensing assembly of a product and the assembly process of the assembly make it possible to obtain a larger internal space for the product, a bottle or a thinner package, which means that it is easy to grasp and dispense the product with one hand, and that less product is left in the pouch and cannot be dispensed.

[0074] Aspects of this disclosure have been described in detail with reference to the illustrated embodiments; however, those skilled in the art will recognize that many modifications can be made to them without departing from the scope of this disclosure. This disclosure is not limited to the specific construction and compositions disclosed herein; all apparent modifications, changes, and variations to the preceding descriptions fall within the scope of the disclosure as defined by the accompanying claims. Moreover, these concepts expressly include all combinations and subcombinations of the preceding elements and features. LIST OF DIGITAL REFERENCES
