[0003] An assembly for packaging and dispensing a product is widely used in cosmetic area. One type of such an assembly is disclosed by JP2017145011A, for example. JP2017145011A discloses a container configured to pour out viscous liquid agents such as a shampoo and a conditioner from a flexible bag-shape container filled with the agents using a pump, which is a dispenser device that can secure a flow path for liquid and reduce remaining amounts of content liquid. The dispenser device comprises a pump device, a flexible bag-shape container and an outer bottle, in which the flexible bag-shape container can be stored inside the outer bottle and the pump device can be connected to the outer bottle and the flexible bag-shape container. The flexible bag-shape container is a pouch container in which at least left and right edges are sealed, which is formed so that left and right widths including the sealed edges are larger than an inner diameter dimension of the outer container before the pouch is filled into the outer container.
[0004] As shown in FIG. 9, the flexible bag-shape container in JP2017145011A is known as a pouch 1'. When filled with liquid, the cross section bulges to form a large diameter section with the seal portions on both sides as shown in the bottom view in FIG. 9, and the width D2'of the pouch 1'from the left edge to the right edge 14'is quite large, and the outer bottle has a big width D2 so that it is not easily gripped and pressed to dispense the product via pumping function with only one hand.
[0005] In other words, due to the pouch, the outer bottle has a long elliptical cross-section which is difficult to grasp with one hand. This is because the size in a major axis direction of the elliptical shape is larger, making it hard for the palm and fingers to completely encircle the outer bottle and apply enough pressure to stabilize it.

However, the meanings of the terms may be changed according to intention of those skilled in the art, a judicial precedent, emergence of a new technology, and the like. In addition, in certain cases, a term may be selected at discretion of the applicant. In such cases, the meaning of the term will be described in detail at the corresponding part in the description of the invention. Therefore, the terms used in the present invention should be defined based on the meanings of the terms and the entire descriptions provided herein without being simply limited to the names of terms.
[0052] In the present disclosure, when some part “includes” some elements, unless explicitly described to the contrary, it means that other elements may be further included but not excluded.
[0053] Hereinafter, an assembly for packaging and dispensing a product according to one or more embodiments of the present invention will be described with reference to FIGS. 1 to 9. The product is in particular a cosmetic, pharmaceutical or dermo-pharmaceutical product, and is preferably highly sensitive formula, such as VC over 12%or retinol and any other oxygen sensitive formula.
[0054] FIG. 1 is a perspective view of an assembly 1000 for packaging and dispensing a product according to one embodiment of the present invention, wherein the assembly 1000 comprises an outer bottle 1 and a cap 9, and wherein the cap 9 is closed onto a dispensing head.
[0055] As shown in FIG. 1, the assembly 1000 for packaging and dispensing a product generally has a shape of right circular cylinder. The outer bottle 1 basically has a shape of right circular cylinder, and the outer bottle 1 may also have other shape for easy grasping, such as, a shape of a regular square prism or polygonal cylinder, for example. When using the assembly 1000, auser generally grasps the body of the outer bottle 1. If the outer bottle 1 has a slim outer 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 therein, as will be described in more detail below.
[0056] FIG. 2 is an exploded perspective view of the assembly 1000 for packaging and dispensing a product according to one embodiment of the present invention.
[0057] As shown in FIGS. 1-2, in one example, the assembly 1000 for packaging and dispensing a product comprises the outer bottle 1, a pouch 2 containing the product, a spout 3 sealing on one end of the pouch 2, a spout collar 4 for holding the spout 3, an airless pump 5, an annular pressing member 6, an actuation member 7, a nozzle 8, and the cap 9. It is to be understood that, some of the components may be omitted or may be formed as one piece. In one example, the pouch 2 is made of a plastic film. In another example, the pouch 2 is made of vacuum metallized PET or vacuum aluminizing casting polypropylene (CPP) , and preferably, the pouch 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 pouch 2 is formed by heat-sealing a film sheet for example made of a laminate of multiple thermoplastic resins that have been given functions such as gas barrier properties. In one embodiment of the present invention, the pouch 2 is formed by heat-sealing one edge 21 along a longitudinal axis X or longitudinal direction of the outer bottle 1, as shown in FIG. 6. The direction of the longitudinal axis X or longitudinal direction can also be called a vertical direction. In contrast thereto, the doy pouch 1'as shown in FIG. 9 has two edges, i.e., left and right edges. The pouch 2 stores the liquid or viscous product to be dispensed. In one embodiment of the present invention, the spout 3 is provided 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 straight line 22, as shown in FIG. 7. The spout collar 4 can be fastened onto the spout 3 by means of a threaded connection, for example. In particular, the spout collar 4 has internal thread 41, and the spout 3 has external thread 31 which is configured to engage with the internal thread 41 of the spout collar 4, as shown in FIG. 4.
[0058] FIG. 3 is a longitudinal cross-sectional view of the assembly 1000 for packaging and dispensing a product according to one embodiment of the present invention. FIG. 4 is an enlarged cross-sectional view of the portion B as circled in FIG. 3 of the assembly 1000 for packaging and dispensing a product according to one embodiment of the present invention.
[0059] The outer bottle 1 preferably has a tubular peripheral wall 11 and a bottom wall 12 which 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 bottom wall 12, so that when the pouch 2 expands, the air in the outer bottle 1 will discharge via the vent 15. A thin-walled part 13 extends from the tubular peripheral wall 11 along the longitudinal axis X of the outer bottle 1, and the thin-walled part 13 is preferably interrupted along a circumferential direction, so that the thin-walled part 13 has a certain degree of elasticity along the longitudinal axis X. In one example, the thin-walled part 13 has one or more annular ribs 14 extending radially outward from the thin-walled part 13, so that it can snap fit with an annular rib 42 extending radially inward from the inner peripheral surface of the lower end of the spout collar 4.
[0060] The airless pump 5 includes a flange 51 near the middle thereof, and when assembling, a lower end of the airless pump 5 will pass through the spout 3, and the flange 51 seats against the top end of the spout 3. The annular pressing member 6 has internal thread 63 at a lower end, and the spout collar 4 has external thread 43 which is configured to engage with the internal thread 63 of the annular pressing member 6. The annular pressing member 6 has a double-wall structure at an upper end, and a pressing annular part 61 extends radially from the inner wall 62 of the annular pressing member 6. When tightening the annular pressing member 6 onto the spout collar 4, the pressing annular part 61 will press against the flange 51 of the airless pump 5, so that the airless pump 5 is fixed in position. The airless pump 5 is a one-way dispensing pump 5, so that the air outside the assembly 1000 will never be sucked in the pouch 2.
[0061] The actuation member 7 is enveloped by the annular pressing member 6 on the peripheral surfaces. The actuation member 7 is formed of a rigid part and slides while being guided within the annular pressing member 6. In one example, the actuation 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 for receiving a nozzle 8, as to be explained below.
[0062] In one example, the actuation member 7 includes an actuating portion 72 to enable dispensing the product. The actuating portion 72 is movable along a longitudinal axis X of the assembly 1000 by a user pressing thereon. Moreover, the actuation member 7 includes a bar seat 73 for receiving the nozzle 8 therein, as will be explained below. The bar seat 73 is aligned with the opening 74 in a horizontal direction.
[0063] In one example, the nozzle 8 includes a nozzle body 81 for dispensing the product to be applied. The nozzle body 81 is fitted into the opening 74 by means of snap 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 than that of the hollow passage 811, and the tapered dispensing opening 812 allows the product to be dispensed therefrom. The nozzle 8 further includes an air closing bar 82 which is arranged in the hollow passage 811 of the nozzle body 81. When the actuation member 7 is not depressed, the air closing bar 82 will abut against and seal the dispensing opening 812 so as to close the hollow passage 811. As the nozzle body 81 only opens in one direction, namely in the dispensing direction, no air can enter the hollow passage 811 and no possibly already contaminated medium can be sucked back again.
[0064] FIG. 5 is a perspective view of an air closing bar 82 of a nozzle 8 of the assembly 1000 for packaging and dispensing a product according to one embodiment of the present invention. In the embodiment as shown in FIG. 5, the air closing bar 82 includes a bar stem 821 which will be inserted into the hollow passage 811 of the nozzle body 81. The bar stem 821 has a tapered end 822 for abutting against and sealing the dispensing opening 812 of the nozzle body 81. Near the middle of the air closing bar 82, there is an elastic sleeve 823. The elastic sleeve 823 has a shape of a bowl nested on the bar stem 821. The elastic sleeve 823 has a slightly larger diameter in a free state than the diameter of the bar seat 73 of the actuation member 7, so that when the air closing bar 82 is inserted into the bar seat 73, the elastic sleeve 823 slides in the bar seat 73 in an air sealing way. Preferably, the air closing bar 82 is formed as one piece.
[0065] In one embodiment, the air closing bar 82 may be made by POE (Polyolefin elastomer) , LDPE, HDPE or PP or other similar materials. The air closing bar 82 may further include an elastic plug 824 on the end opposite to the tapered end 822. The elastic plug 824 is made of elastic material, and the elastic plug 824 acts as a spring. In other words, when the actuation member 7 is depressed, here in response to vertical manual pressure exerted on the actuating portion 72, the product will be pumped by the pump 5 to a space between the opening 74 and the air closing bar 82, and the product will apply a pressure onto the elastic sleeve 823 to compress the elastic plug 824, and thus the bar stem 821 will leave 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 actuating portion 72, i.e., the actuation member 7 is no longer depressed, the elastic plug 824 will automatically rebound back, rendering the tapered end 822 abutting against the dispensing opening 812 of the nozzle body 81 again. The dispensing 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.
[0066] In one embodiment of the present invention, the actuation member 7 and the nozzle 8 together constitute a dispensing head. When not in use, the cap 9 will be closed onto the dispensing head, so as to protect the dispensing head and avoid dispensing the product unintentionally.
[0067] FIG. 6 is a perspective view of a pouch 2 and a spout 3 of the assembly 1000 for packaging and dispensing a product according to one embodiment of the present invention. FIG. 7 is a top plan view of the pouch 2 and the spout 3 of the assembly 1000 for packaging and dispensing a product in FIG. 6 according to one embodiment of the present invention. FIG. 8 is a bottom plan view of the pouch 2 and the spout 3 of the assembly 1000 for packaging and dispensing a product in FIG. 6 according to one embodiment of the present invention.
[0068] In one embodiment of the present invention, the pouch 2 is formed by heat-sealing one edge 21 along a longitudinal axis X of the outer bottle 1. In one example, the pouch 2 is formed by heat-sealing a film sheet for example made of a laminate of multiple thermoplastic resins that have been given functions such as gas barrier properties. In other words, firstly, a film sheet is sealed along a longer side to form a longitudinal sealing edge 21, and now the film sheet is formed as a cylinder which is open on the upper end and lower end. Then, the upper side of thus formed cylinder is sealed onto the spout 3 along a horizontal straight line 22, as shown in FIGS. 6-7. Thereafter, the lower end of thus formed cylinder is sealed along another horizontal straight line 23, as shown in FIGS. 6 and 8. In other words, a pouch 2 is horizontally sealed by a first sealing end 22, and is sealed by a second sealing end 23 in a direction which is different from that of the first sealing end 22. The sealing process is preferably a heat-sealing.
[0069] As shown in FIG. 6, thus formed pouch 2 has a shape of a triangular pyramid. In one example, the pouch 2 has triangular surfaces 24, 25 and 26 as shown in FIG. 6. On the opposite side, the pouch 2 also has triangular surfaces which are rotationally symmetric to the triangular surfaces 24, 25 and 26 with respect to a central longitudinal axis of the spout, as shown in FIGS. 6-8. In this way, the pouch 2 has a shape of a cross sealed triangular pyramid. As shown in FIGS. 6-8, the first sealing end 22 is basically 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 to 120 degrees, preferably between 70 degrees to 110 degrees, more preferably between 80 degrees to 100 degrees, even more preferably between 85 degrees to 95 degrees, and most preferably the angle is 90 degrees. In other words, the flexible cross sealed triangular pyramid pouch 2 looks as if the second sealing end 23 is twisted an angle with regards to the first sealing end 22, such as twisted about 90 degrees.
[0070] 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 larger 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 larger than the diameter or a diagonal length in a horizontal section of the outer bottle 1. As the pouch 2 is made of flexible or soft material, the first sealing end 22 and the second sealing end 23 can bend to some extent, so that the pouch 2 is easily inserted into the outer bottle 1 from the open top thereof.
[0071] Regarding a method of assembling the assembly, the pouch 2 is firstly sealed onto the spout 3. Then the spout 3 is fixed onto the spout collar 4 for example by threaded connection. Then the combination of the pouch 2, the spout 3 and the spout collar 4 are fixed onto the outer bottle 1 by means of a snap fit between the one or more annular ribs 14 of the thin-walled part 13 and the annular rib 42 of the lower end of the spout collar 4. Then the pouch 2 is blown by gas pressing force to expand to the tubular peripheral wall 11. The blowing process may be performed by inserting a blowing tube of a gas blowing machine into the spout 2. In other words, the pouch 2 expands to conform to the shape of the outer bottle. In this way, a largest inner space is created for the pouch 2, because the pouch 2 almost fully fill the inner volume of the outer bottle 1. Thanks to the cross sealed triangular pyramid pouch shape and the material for the pouch, the pouch now will remain to the expanded shape, without returning to the unblown shape. After then, the product is filled into the pouch 2 from the spout 3. After the product is filled, the airless pump 5 is inserted onto the spout 3 and is fixed by tightening the annular pressing member 6 onto the spout collar4. After then, the dispensing head including the actuation member 7 and the nozzle 8 is arranged onto the annular pressing member 6 and airless pump 5, and then process of assembling the assembly 1000 for packaging and dispensing a product is finished.
[0072] In one embodiment of the present invention, by using the one-way dispensing pump 5, the flexible cross sealed triangular pyramid pouch 2 gradually contracts, allowing the product therein to be dispensed. As the first sealing end 22 has a different horizontal orientation than the second sealing end 23, when the product is used up, the cross sealed triangular pyramid pouch 2 is shrinking with a cross section like a picture. Therefore, a restitution ratio is minimized, and thus nearly all of the product in the pouch 2 are dispensed and used. After many times testing, it has been demonstrated that over 95%of the products in the pouch can be dispensed.
[0073] Moreover, thanks to the cross sealed triangular pyramid pouch 2, a bigger inner space is formed compared with other shapes of the pouches. For example, an inner space for the cross sealed triangular pyramid pouch 2 is bigger than an inner space for the pouch as shown in FIG. 9, because the cross sealed triangular pyramid pouch 2 can nearly expand to conform to the shape of the outer bottle 1. In this way, more products can be filled in the cross sealed triangular pyramid pouch 2 than in a pouch.
[0074] Thanks to the design of the cross sealed triangular pyramid pouch together with the airless nozzle and the airless pump, the assembly for packaging and dispensing a product and the method of assembling the assembly achieves an increased inner space for the product, a slimmer bottle or package which means that it is easy to grasp and dispense the product with one hand, and less product being left in the pouch and unable to be dispensed.
[0075] Aspects of the present disclosure have been described in detail with reference to the illustrated embodiments; those skilled in the art will recognize, however, that many modifications may be made thereto without departing from the scope of the present disclosure. The present disclosure is not limited to the precise construction and compositions disclosed herein; any and all modifications, changes, and variations apparent from the foregoing descriptions are within the scope of the disclosure as defined by the appended claims.
