Description

[Technical Field]

[0001] The present disclosure relates generally to containers for fluids. More particularly, the present disclosure relates generally to , relates to a container having a closure cap. [Background technology]

[0002] Fluid containers may be subject to extreme temperatures, particularly during transport and / or when the container is placed in any configuration. There are occasional problems with dosing and leakage. Consumer products can suffer from such drawbacks. For example, ketchup or A thixotropic fluid, such as a soup, sometimes forms an "X" shaped slit. These are sold in bottles that use a flexible plastic film with Inverted bottles that rest on the cap so that gravity holds the product adjacent to the valve It is sometimes used in Summary of the Invention [Problem to be solved by the invention]

[0003] One problem with this type of valve is that in some cases the product may leak out of the bottle. The valve can leak when not in use. Another problem is that the valve can leak while dispensing. This can cause the product to spray out of the opening at an undesirably high velocity, increasing the risk of splashing. The high rate of product discharge also contributes to proper dosing. This generally means poor product control at high speeds. The third problem is that the valve resists air inflow to maintain the internal volume after dispensing. Resistance or obstruction may create a sub-atmospheric pressure, i.e., a partial vacuum. This prevents paneling, i.e., buckling, or other damage to the vessel wall. This can cause undesirable inward deflection, which can lead to aesthetic and even functional problems. This increases the manual pressure required to dispense the product, i.e., squeeze, That is, uneven or inconsistent dispensing in response to manual application of pressure to the exterior of the container may occur. There it is.

[0004] Another problem is that these thin film valves are often made of silicon and The other parts of the cover are often made of other materials such as polypropylene. Having a closure cap made of several materials increases the complexity and manufacturing costs and This may make cycling difficult and / or infeasible, making it unsuitable for large-scale use. Making this solution unattractive.

[0005] Furthermore, such thin film valves and other similar solutions are suitable for relatively low viscosity serums, or other thin liquid components separate from the rest of a liquid such as ketchup. However, they do not always adequately address the product separation that often occurs in fluids. This separation increases leakage. This can increase splashing and cause thin liquid ingredients to separate and dispense from the rest of the product. There is a problem. [Brief explanation of the drawings]

[0008] Elements in the drawings are illustrated for clarity and have not necessarily been drawn to scale. For example, the dimensions and / or relative positioning of some elements in the drawings may vary depending on the various aspects of the present invention. In some cases, the dimensions of certain elements may be exaggerated relative to other elements to help understand the particular embodiment. To facilitate a less intrusive review of these various embodiments, commercially viable implementations are Common and well-understood elements that are useful or necessary in the design may be omitted. Although some acts and / or steps may be described or illustrated in a particular order of occurrence, sequence Such special attention to is not really necessary. The terms and expressions used in this specification are , unless a different specific meaning is otherwise stated, a person skilled in the art of the above-mentioned art would understand the meaning of Such words and expressions have their ordinary technical meanings according to the terms.

[0009] For example, to dispense fluids such as thixotropic fluids from a bottle. Useful systems, devices and methods are described. Some embodiments are for such bottles. The closure cap has a flip top, a base, and a disk. and the base and disc may comprise a mixing mechanism configured to promote mixing of the fluids. The mixing chamber defines a chamber for introducing serum or liquid separated from the fluid into the fluid. In some embodiments, the base can be mixed back in. a hollow inner shaft having a central opening and a non-planar end surface opposite the central opening; The non-planar end surface and the disc are one or more between the mixing chamber and the interior of the shaft. (In other embodiments, the shaft defines one or more channels opposite the open side.) The shaft may have a planar end surface and the shaft may have an aperture formed therein. In some embodiments, the disk has a central opening and a planar surface of the disk. The bottle has a plurality of partial annular openings extending through its surface and a protrusion extending into the mixing chamber. To flow out of the reservoir or bottle, the fluid must pass through the opening in the disc (e.g. through a partial annular opening or a central pinhole) and formed by an internal shaft. The fluid advances through a chute and through a central opening in the base. is advanced through these openings and passages by applying manual pressure to the body of the bottle. do.

[0010] In some embodiments, the dispense bottle includes a container body having an externally threaded neck. The external threads are threaded to the internal threads on the base and the closure cap, including the flip-top lid. In one exemplary embodiment, the base of the closure cap has a base thread. The base threads are threaded to the external threads of the bottle neck. Further, in some embodiments, the base is configured to engage an inner surface of the base. one or more retaining elements, protrusions or rings (such as on the inner surface of the skirt) a central portion having an opening aligned with the inner shaft, the opening being such that when unobstructed, One approach is to have the inner shaft extend opposite the central section. The inner shaft terminates in a non-planar end surface. The disk may have a

[0011] As mentioned above, the cap has a flip-top lid and in one exemplary form The flip-top lid has an internal protrusion movable between a first closed position and a second open position. In the first position, the protrusion prevents or inhibits the flow of fluid from the interior of the container body. In the first position, the opening in the base is blocked, and in the second position, the opening in the base is allowed to flow. Additionally, in one exemplary embodiment, the disk is snapped into place with a retaining ring. The disk is attached to the inside of the base by the central opening and the In one exemplary embodiment, the cardiac opening has a partial annular slot disposed about the opening. The central portion of the disk and base along with the inner shaft form a mixing chamber. Additionally, in some embodiments, multiple fluid channels may be formed on the non-planar surface of the inner shaft. The end face and the disc form a channel for the fluid to pass from the mixing chamber to the inner shaft. It can flow within.

[0012] In some embodiments, the closure cap, when in the closed position, secures the bottle. When in an inverted position, whereby the bottle opening is positioned below the container body, the thixotropic The fluid can be kept in a stable equilibrium state within the bottle without leakage. When the closing cap is in the open position, the closing cap The cap configuration allows for controlled dispensing of thixotropic fluids, and pressure relief on the container body For example, air may be allowed to flow back into the container body, and the internal channel of the thixotropic fluid may be This allows for quick interruption of dispensing by allowing for spring back and backflow into the syringe. Furthermore, one approach is to replace the amount of fluid dispensed by this spring back. This allows air to flow into the bottle instantly, allowing the bottle to quickly restore its original shape. This is achieved by:

[0013] In one exemplary approach, at least a portion of the fluid is directed downward through the partial annular opening. advances to the mixing chamber, then between the disc and the non-planar end of the inner shaft. The fluid flows inward into the defined fluid channel, then down the shaft, and then into the center. It flows out of the dispensing bottle through an opening. One approach is to place a The thixotropic fluid advances through the partial annular opening of the disc and dissolves any separating serum. The thixotropic fluid passes through a mixing chamber that allows it to be mixed into the inner shaft. The flow passes through the central opening in the base and into the channel formed by the edge of the base and the disc. It can be squeezed out of the bottle to release the liquid. downward through a small aperture or pinhole in the base and forward through the central opening in the base. As mentioned above, when pressure on the bottle is interrupted, the bolt The air can be transported through one or both of these routes, e.g. For example, it may enter the bottle via pinholes and / or annular openings in the disk. This allows air to pass through the inner chambers, channels, pinholes, and mixing chambers. and / or the partial annular opening into the bottle. When pressure is released on the body or vessel, it is pulled into the bolt. In short, air is admitted into the main cavity of the bottle, and this admission is This is done by flowing through a central pinhole or a partial annular slot in the disk. After the disc is installed in the base of the closure cap, one approach is to The base remains stationary relative to the base.

[0014] In some embodiments, a closure cap includes a base, a flip top, and a disk. The cap is made of polypropylene material so that the entire closure cap can be recycled as a unit. Furthermore, without the silicon membrane, the strength of the closure is It does not degrade significantly over time, and its performance does not degrade much over time. In some embodiments, fluid is removed from the bottle over the life of the bottle. Little or no pressure change is required to dispense.

[0015] As described herein, a closure cap can allow for better dose administration. This prevents the bottle from accidentally expelling the product at high speed, which may otherwise occur. It is possible to prevent permanent crushing or other permanent inward deformation of the bottle. The cap shape can reduce splashing. The chamber may be adapted for external cleaning, for example by having an outwardly convex or domed exterior surface. The device can be configured to facilitate easy switching.

[0016] One approach is to use an outer bottom ( The surface (when the bottle is inverted) is arc-shaped or dome-shaped with a flat peripheral surface. In one embodiment, the inner surface of the base is at least partially connected to the skirt of the base. In some embodiments, the base has an internal shaft that projects slightly parallel to the center. an internal cutting blade disposed adjacent the cardiac opening, The inside diameter of the shaft decreases rapidly. One approach is to use a cutting blade with sharp, notched edges. In some configurations, the inner diameter of the aperture itself is different from the inner shaft wall. More specifically, in such configurations, the diameter of the opening to the vessel is The diameter between the walls of the casing is smaller than that of the wall of the casing, and this reduction in size and the relatively sharp edge between the two To help reduce drip formation of product by effectively retaining product within the closure Additionally, the surface tension and size of the openings may also be adjusted to reduce drip formation of the product. The cutting blade can assist in preventing the product from flowing out of the opening in the closure cap. It does not prevent the flow of fluid, but it slows the flow, thereby reducing the amount released under a given pressure. One approach is to make the cutting blade relatively small compared to the shaft diameter. In some embodiments, the internal cutting blade has a width of about 1 mm and The opening itself has a diameter of about 3 mm to about 7 mm. In yet another embodiment, the opening has a diameter of about 4 mm to about 4.5 mm. The cutting blade has a diameter of approximately 6 mm, and the inner shaft has a diameter of approximately 6 mm. In some forms, it has a width of about 1 mm.

[0017] The cutting blade helps to quickly interrupt fluid dispensing when pressure is released on the bottle. At the same time, the disc (and its interface with the internal shaft) is This reduces the pressure that is generated, which aids in interrupting the dispense. The size and shape of the openings in the mask assist in monitoring the flow and also determine the viscosity and shape of the product. The geometry of the disk can be adjusted to accommodate different fluids. It is possible.

[0018] At the upper end of the inner shaft located away from the opening in the base, several In an embodiment, the inner shaft has a non-planar end surface. The non-planar end face has a stepped configuration that creates a plurality of teeth and a plurality of recesses. The non-planar end surface may be configured to have a sinusoidal wave or other arc-shaped depression.

[0019] As mentioned above, the bottles and caps described herein are suitable for a wide variety of fluids. In one exemplary embodiment, the bottle may be adapted for use with, for example, Some spices, thixotropic fluids such as sauces, or shampoos or body washes Such applications are particularly advantageous as they are That is, the consumer or user may splash fluids or cause other unintentional soiling. This is because it allows the desired amount of fluid to be dispensed easily and quickly without causing any trouble. One approach is to use a dispensing bottle with a closed cap, which can hold from about 250 mL to about 1 Furthermore, various container shapes are conceivable, and the container may have a capacity of 1000 mL. One exemplary approach is to store the bottle in an inverted position, with the bottle resting on the top. The disc has a diameter of about 20 to 40 mm, and the inner shaft is about 4 to 12 mm. In another embodiment, the inner shaft has a height of about 5 to 9 mm and a diameter of about 3 to 9 mm. It has a height of 9 mm and a diameter of about 3 to 5 mm.

[0020] As mentioned above, the closure cap is a portion of the base with a disk secured to the base. In one approach, the mixing chamber is formed by The disk has a plurality of extensions protruding from it. More specifically, the disk has several In this configuration, the mixing chamber extends downward from the bottom of the disc (when the bottle is inverted). The mixing chamber described herein has extensions as a plurality of flanges projecting into the In part, the serum separated from the thixotropic fluid is mixed back into the remaining thixotropic fluid. This helps prevent the serum from leaking from the dispense bottle. As a countermeasure, the mixing chamber mixes the separated serum back into a thixotropic fluid. By allowing the separation serum to flow out of the opening in the dispenser, the separation serum will leak out of the dispenser bottle. In some embodiments, the mixing chamber is 2 mL to 11 mL, 3 mL having or holding a volume of up to 9 mL, or 5 mL to 7 mL, or about 6 mL. The extension slows the fluid flow through the mixing chamber, creating or increasing turbulence. and / or otherwise increase the interaction between the separating serum and the rest of the fluid. This can aid in remixing of the separated serum.

[0021] One approach is to provide multiple retaining rings, one of which is The first is a closure cap that is attached to the bottle so that the bottle can be sealed. For example, the first retaining ring and the second retaining ring may have a liner for the bottle or cap. The second retaining rings are spaced axially (vertically) from each other and capture the edge of the disk between them. The upper ring (when the bottle is inverted) can be removed from the bottle before use. a removable film or liner member associated with the box to seal the opening in the box; The liner member may be manually removed by the consumer prior to dispensing the product. can be done.

[0022] Bottles with the closure caps described herein are suitable for high speed, high volume, mass production operations. It can be formed, filled and sealed in a vacuum or other type of operation. Dispensing bottle manufacturing methods generally include, for example, blow molding, injection molding, forming a squeezable flexible bottle by injection molding or other methods; Alternatively, a disk and a closure cap having a base and a flip-top lid may be provided. forming a disk on the base; snapping the disk onto the base; and flowing the disk into the receptacle. Filling the container with a substance (such as a thixotropic fluid) and attaching a closure cap to the filled container. and securing the base to the receiver. The base thread is provided on the inside of the skirt (the base thread is the external thread of the bottle neck). the inner skirt and the outer skirt, and the inner skirt and an inner shaft terminating in a non-planar end surface opposite the central opening. and a central dome-shaped portion having an opening aligned with the opening. The flip-top lid has an opening through which fluid can flow when the flip-top lid is not closed, and the flip-top lid has a first position and a second position. The nozzle has an internal projection movable between two positions, the projection preventing the flow of fluid when in the first position. and blocking the opening in the base to inhibit or prevent leakage of the fluid from the opening in the base when in the second position. In some embodiments, the disk has a central pinhole. a partially annular groove disposed around the central pinhole; The central portion, the inner skirt, and the outer surface of the inner shaft define a mixing chamber, and the inner skirt A plurality of fluid channels are formed between the non-planar end surface of the shaft and the disk. In one embodiment, the method further comprises attaching a closure cap to the bottle body to seal the product in the bottle body. and sealing the receptacle with a removable liner attached thereto. As will be described in detail, the base and flip-top lid may be molded together with the disk or separately. It is possible.

[0023] In one exemplary embodiment, the container closure cap comprises a flip-top lid and at least , a dome-shaped wall with an opening through it, an inner skirt, and an upper flat portion connected together an outer skirt, threads on the inner skirt and one or more retaining rings, and and a base having an inner shaft depending inwardly from said domed wall. In one approach, the inner shaft terminates on a non-planar end surface. In this embodiment, the flip-top lid has a protrusion, and the protrusion blocks the opening. and a second position in which the projection does not block the opening in the base. The closure cap, in some configurations, snaps onto the disk and onto the retaining ring. In this configuration, the disk is attached to the inside of the base by a The disk has a central pinhole, a partial annular groove disposed around the central pinhole, and a base. a flange projecting toward the base, the flange being adapted to allow the disk to be attached to the base; When attached, the inner shaft is disposed between the partial annular slot.

As shown in FIG. 1, the base 20 further includes a flip-top lid 22 (which holds the bottle) underneath. The base 20 has ribs 80 disposed on a portion of the base 20 in the upright position. provides a gripping surface to prevent someone from removing the entire closure cap 18 from the container body 12. If desired, the user can easily grasp the closure cap 18 and remove the base 20. The internal threads 32 can be disengaged from the external threads 16 on the neck 14. In this case, the rib 80 can be omitted from the closure cap 18.

[0032] 5 and 9 show an example of a non-linear end surface 38 on the base 20 inner shaft 36. In some embodiments, the nonlinear end surface 38 allows both the fluid and the air to mix. A channel opening is formed for transition between the member 56 and the inner shaft 36. As an approach, the nonlinear termination surface 38 may have a stepped configuration 64, as shown in FIGS. In yet another approach, the nonlinear termination surface 38 may be wavy, sinusoidal, or In some embodiments, the nonlinear termination surface 38 may be an internal shell. The shaft 36 may have a semicircular recess cut into the wall. A number of recesses define one or more channels between the mixing chamber 56 and the inner shaft 36. can be formed.

[0033] Additionally, the stepped form 64 shown in FIGS. 5 and 9 may include one or more protruding teeth 68, and One or more deep slots extending intermediate or otherwise positioned between the teeth. 64. The step at the non-linear end surface 38 of the inner shaft 36 The features 64 are fluid channels that vary in width and / or depth in coordination with the surface of the disk. 58. As shown in FIG. 10, the nonlinear termination surface 39 may also be in the form of a wave or arc. , a plurality of slots or recesses 65 and rounded protrusions 69. The wavy nonlinear termination surface 39, which acts similarly to the ridged configuration, forms a channel with the disk 42. 58. In some embodiments, the nonlinear termination surface may be, among other elements, The ribs may have a combination of stepped portions, protrusions, angled, and / or curved sections. do.

[0034] In fact, the nonlinear termination surface 38 can take a variety of forms, for example, as shown in FIGS. 9 to 44. As mentioned above, the non-linear The shaped surface 38 has a stepped configuration that forms a number of channels 58. Additionally, other shaped In this state, the nonlinear termination surface 39 shown in FIG. 10 has a wavy or sinusoidal configuration. 8 and 9. FIG. 40 shows a non-planar surface 2238 having two heights and an angled portion between them. 41 shows a linear termination surface 2338 disposed between protrusions or projections having a triangular cross section. FIG. 42, similar to FIG. 39, shows a nonlinear termination surface 2438 having a generally v-shaped valley. 41 shows a nonlinear termination surface 2538 having three different heights, the protrusions or projections in FIG. It has a rectangular or trapezoidal shape, with a more acute or lesser angle adjacent to a larger base. FIG. 43 shows a nonlinear termination surface 2638 having a stepped configuration, where The lowest step has a width smaller than the width of the highest step. Finally, FIG. 44 shows a triangular shaped protrusion or shows a nonlinear termination surface 2738 having protrusions with u-shaped valleys between them. Features may be used as shown or in combination with other exemplary features, e.g., features shown in other figures. Alternatively, the end of the shaft can be linear or flat, and The shaft may have other openings incorporated therein.

[0035] In addition to partially defining the mixing chamber 56, the disc 42 also serves to trap the fluid (and its contents). The annular groove (partial groove) defines an annular partial slot or opening 50 that allows flow into the mixing chamber. The openings 50 can take a variety of forms, for example, as shown in FIGS. 7A, 7B, and 45A-45I. One approach, shown in Figures 7A and 7B, is to In another embodiment shown in FIG. 45A, disk 1242 has four openings. In another embodiment, FIG. 45B shows a circular aperture 1250 having three annular apertures 1250. However, the embodiment of FIG. 45C has five openings 1350. FIG. 45D has six openings 14 45E shows an example disk 1442 having seven annular openings 155. 45F shows an example disk 1542 having a 0. It has eight annular openings 1650 and offset pinholes 1648, as shown in FIGS. The pinholes are shown positioned at the center of the discs at 45E and 45G-45I. The corners of the annular openings shown in Figures 7A, 7B, and 45A-45F are free from any sharp edges. 45G to 45I show openings 1 with less roundness or no pinch points. 750, 1850, and 1950. These features can be combined in various ways. This can be done.

[0036] Figures 47A-47I also show how to manage the flow of fluids from the bottle through the cap. As mentioned above, the bottle is They are often stored and / or used in a folded-down position, in which case the The serum may partially leak out of the bottle, which means that the bottle An extra long flow path that allows the serum to mix back into the fluid before exiting the cap, or Because they don't have the time.

[0037] To facilitate mixing of any separated serum with the rest of the fluid, the disc Incorporating a number of additional features, for example, additional openings located within the flange In one exemplary embodiment, these openings may be annular slots and, as described above, A central pinhole may be located midway between the center of the disk and the center of the disk. One example disk 2042 shown in FIG. 7A has an annular opening 2042 inside a flange 2054. 051, which itself is inside a larger annular opening or slot 2050. In this way, adjacent to the inner wall of the flange 2054, the fluid and any segregated material can be There is a smaller inner opening 2051 that aids in mixing the components. C is similarly adjacent to the flanges 2154, 2254 and the annular openings or slots 2150, 2250. Exemplary disks 2142, 2242 having adjacent intermediate or inner openings 2151, 2251 47A, but the shape and size of these openings are configured differently compared to those in FIG. Furthermore, Figure 47C has no central pinhole, while Figures 47A and 47B have In addition to these configurations, pinholes, as previously suggested, The disk may also be offset from the geometric center of the disk.

[0038] 47D-47F show a method for facilitating mixing of fluids as they move out of the cap. 10 shows a further exemplary embodiment of a disc having posts protruding from the disc to After installation or fastening to the rest of the cap, the post is typically attached to the outlet or For example, the exemplary disk 2342 (FIG. 47D) has an annular opening 2 350 and a relatively smooth-sided centrally located post 2353. The illustrated example disk 2442 includes an annular opening 2450, a flange 2454, a centrally located port 2456, and a Post 2353 has a relatively rounded outer surface, while post 24 53 has non-uniform sides with a generally x-shaped cross section.

[0039] The posts are shown centered, but can be off-center or multiple. Posts can be integrated into the disc. In addition, the posts can be made with various surface textures. In fact, based on the fluid moving through the cap, A variety of posts with different configurations can be incorporated into the cap.

[0040] In some configurations, instead of a post, the disc may be replaced by another similar structure, such as a cone. The device may have a conical extension 2857 with an opening 2848 therethrough. The central portion of disk 2842 is shown. Additionally, disk 2842 has an annular opening 2851, a It also has a lunge 2854 and an opening 2850 .

[0041] The disk 2542 of FIG. 47F similarly includes a centrally located post 2553 having a generally x-shaped cross section. and an annular opening 2550. However, instead of discrete flanges, the disk 25 42 has one continuous flange or cylindrical wall 2555 protruding from the disk 2542. The cylindrical wall 2555 is shown approximately perpendicular to the disk, but is similar to the flange shown in FIG. 46B. Similarly, they may protrude from the disk at angles other than perpendicular.

[0042] FIG. 48 shows the disk 2542 secured to the remainder of the closure cap 2518. Additionally, the post 2553 is adapted to extend at least partially into the inner shaft 2536. In this way, the fluid flows from the annular opening 2550 over the cylindrical wall 2555 or around it, over or around the end of the inner shaft 2536, and through the shaft You must then proceed along post 2553 to opening 2534. Such a configuration with a flow path is particularly suited to certain fluids with special fluid properties. It is possible.

[0043] Other variations and combinations of the features described herein can be made. For example, Figure 47G shows 47B shows a disk 2642 similar to disk 2142, but with flange 2654. 47B. The flange 265 of FIG. 47G is not longer than that of FIG. 47B. 4. Furthermore, FIG. 47H shows that the fluid has more room or space to move between openings 27. 51, with no flange disposed between them. Many of the various structural features of the disk, including those described herein, are The cap can be removed from the bottle and replaced with a new one. The disc can be tailored to suit the characteristics of the moving fluid.

[0044] As described above, the disk 42 and the inner shaft 36 form a The mixing chamber 56 and opening allow for accurate dispensing and dosing of the fluid 5 within the container. Therefore, the geometry of the disc 42 helps to promote proper dispensing of the fluid 5. stand.

[0045] FIG. 7A shows a disk 42 having a flange 54 that projects downward when the bottle is inverted. 1 shows a first side of the disk 42 between the retaining rings of the closure cap 18. When installed in place, it faces the inner shaft 36. The flange 54 is 42 (as shown in FIGS. 7C-7E), flange 54 It may protrude from the disk 42 at an angle other than 90°. Referring back to FIG. 46B, two exemplary flange configurations are shown. 46B shows a flange 54 projecting at approximately 90° from the body of disk 42, while FIG. 2. The flange 54' projects from the body of the casing 2 at an angle of less than 90°. The flange impacts the flow of fluid 5 entering the mixing chamber 56 and also The flange shown in both Figures 46A and 46B can affect the mixing action within the tank. Both types of flow control the product mix as it progresses towards the outlet based on the product's flow characteristics. However, the angle of the flange 54' shown in FIG. 46B may be less than 90°. As mentioned above, a central pin is disposed through the center of the planar portion of the disk 42. The through hole 48 is partially surrounded by a plurality of slots or partial annular openings 50. The partial annular opening 50 is significantly larger than the central pinhole and allows for flow out of the bottle 10. The majority of the animal 5 advances through the partial annular opening 50. In some embodiments, The bracket 42 has a diameter of 20 mm to 40 mm, 25 mm to 35 mm, or about 30 mm to 34 mm. In one exemplary embodiment, the disk 42 has a diameter D1 of about 31.9 mm ± 0.1 mm. In one approach, the annular groove has a diameter D1 of 10-15 mm, or 11 The arc length of each aperture is approximately 12 mm. 7 mm. Additionally, the annular opening 50 may have an inner curvature at the inner edge of the opening. The opening has a radius R1 and an outer radius of curvature R2 at the outer edge of the opening. In this case, R1 is about 6 to 10 mm, and R2 is about 10 to 15 mm. In an exemplary approach, R1 is approximately 8-9 mm and R2 is approximately 12-13 mm. In one exemplary embodiment, R1 is about 8.3 mm and R2 is about 12.3 mm. be.

[0046] As shown in FIGS. 6 and 7A, the partial annular opening 50 is disposed adjacent to the flange 54. When the disk 42 is installed in the base 20, these flanges 54 are inserted into the mixing chamber 56. The fluid 5 (including any components such as serum) is then directly injected into the opening 5 0 and forward into the inner shaft 36 to exit the bottle, Additionally, the portion of fluid 5 advancing through opening 50 is mixed before the fluid exits bottle 10. must enter chamber 56 (which separates the fluid 5 from the (This facilitates mixing of any components.) In one exemplary approach, an extension The portion or flange 54 has a height h1 of about 2 to 5 mm. In one exemplary embodiment, h1 is about 3.5 mm. Furthermore, in operation, the length or height of the flange 54 is determined by the non-linear end surface 38. This can be linked to the depth of the channels 58 that are formed, i.e. The similar size of the annular opening 50 and the fluid channel 58 are directly connected. This helps promote mixing by requiring the fluid to flow around flange 54 without any friction. In one exemplary approach, the height h2 of the disk 42 is about 3 to 7 mm. In another exemplary approach, the height h2 of the disk 42 is about 4 to 6 mm. In yet another exemplary approach, the height h2 of the disk 42 is about 4.8 mm. be.

[0047] The width w1 of the planar portion of the disk 42 shown in FIG. 7D is, in some embodiments, about 0. In one exemplary approach, the width w of the disk 42 is between 0.75 mm and about 3 mm. In one exemplary approach, the width w of the disk 42 is about 1 mm to about 2 mm. As shown in FIG. 2, the width d2 of the central pinhole opening 48 is about 1 to 1.3 mm. In one exemplary approach, the width d2 of the pinhole in the disk 42 is It is about 1.5mm.

[0048] As shown in FIG. 7E, each partial annular opening 50 extends from the surface of the disk 42 facing the base 20. The surface can have a beveled edge. This orientation is suitable for holding the bottle cap-side up (upright). When the bottle is placed in this form, the fluid 5 (e.g., at least one of the fluids 5 is retained within the inner shaft 36) The flow of the fluid (a portion of the fluid that is not retained) can be promoted to flow back into the container body 12. Additionally, the beveled edge encourages air to move back into the bottle, reducing the risk of the bottle or container body 1 The bounce back of 2 can be improved.

[0049] To facilitate proper dispensing of the fluid, the geometry of the disk 42 may be, for example, a flange. The size, shape, and angle of the flow of fluid 5 are included to control the flow of fluid 5. In addition, the disc 42 has sufficient openings relative to the area of the disc 42 to allow the fluid 5 18. This promotes sufficient flow of the fluid while still preventing leakage through the closure cap 18. The opening 50 facilitates fluid flow allowing for easy dispensing and quick rebound of the bottle. In one exemplary approach, the disk The total area is approximately 800mm 2 and the total area of the partial annular opening 50 and the central pinhole is Approximately 211mm of the area 2 This is about 26% of the total area of the disk. As a result, the total area of the disc openings covers approximately 20-35% of the total disc area. Also, the partial annular opening generally has a significantly larger area than the central pinhole.

[0050] In Figure 4, the flow of ketchup during dispensing is shown as a dashed line. The thick solid line shows the air flow into the bottle replacing the ketchup. The flow of serum separated from the animal 5 into the mixing chamber 56 is shown. Reconstitute and mix with fluid 5.

[0051] In some exemplary approaches, the closure cap 18 (e.g., the base 20, flip The top lid 22 and the disk 42 are made of a single material, such as polypropylene or other Constructed of food-grade plastic or polymer, or similar recyclable material. In operation, having a closure cap 18 made of a single material allows for recycling of the material. In some approaches, the material can be applied to specific surfaces. For example, the surface of the disk 42 (and potentially the closure cap) can be selected for tension. The inner surface of the nozzle (the nozzle) has roughness that creates flow resistance and helps control the flow of the fluid being dispensed. As will be described in more detail below, the inner shaft 38 Surfaces can also be textured to impede flow or to facilitate the movement of fluids through them. A smooth surface can be achieved, which results in faster and / or more controllable application. This results in less fluid flow and reduces the surface tension of the product or The finish of the material or the manner in which the element is formed can also affect the element. can affect the surface tension of the material and help to facilitate control of fluid flow. For example, some portions of the flip-top cap 18 may affect the flow of the fluid 5 passing therethrough. The surface can be formed to produce a roughened surface that provides

[0052] Returning momentarily to FIG. 38, two different exemplary finish sections 77 and 79 are shown. The single interior wall 78 may have an entire surface of a single texture or surface portions with different textures. 38, the cap 2018 has a first portion 2078 having a rough texture and a smooth As mentioned above, the surface of the material forming the cap 18 is The surface can obstruct, slow or restrict the flow of fluid 5 within the bottle. A part or the whole of the inner shaft may or may not have a textured surface, for example, on the inner wall of the inner shaft. This may depend on the type of fluids that advance through Cap 2018.

[0053] As shown in FIG. 6, the first side of the disk 42 (which is the inner shaft of the base 20 when installed) The flange 36 is located adjacent to the outlet 36 and has a rainbow-shaped or arc-shaped flange or When the disk 42 is mounted on the base 20, an arcuate flange or The extension 54 projects into the mixing chamber 56 toward the base 20. The portion 54 allows the fluid 5 to pass through the annular opening 50 without passing directly through the fluid channel 58. The fluid 55 in the mixing chamber 56 needs to move around the flange 54. Promotes mixing of

[0054] As shown in FIG. 8, the base 20 and inner shaft 36 at the opening 34 are The inner shaft has a cutting blade or shelf 60 on its inner surface where the inner diameter of the inner shaft abruptly decreases. For example, the diameter of the inner shaft may suddenly decrease at this shelf 60, thereby allowing the container body to Manual pressure against the ledge overcomes the tendency of the ledge to retain the fluid within the closure cap. By partially holding the product in the closure until it is large enough to hold one The sharp edges help to reduce the formation of tails on the product. The cutting blade has a sharp edge without burrs. The diameter of the mouth is smaller than the diameter of the inner shaft, and this reduction in size and the relatively sharp edge The cutting blade cuts off the closing cap. The flow of product from the opening in the bottle is not obstructed and the flow is slowed down. One approach is to use a cutting blade that , which is relatively small compared to the diameter of the shaft, and the opening into the container itself is about 3.5 mm to about 4.5 mm. mm, and in one exemplary embodiment, about 4 mm.

[0055] As mentioned above, the inner shaft 36 is positioned such that when the disk is attached to the base 20, One approach is to use an internal shaft to support the disk 42. The inner wall or inner wall 78 of the lid 36 funnels the fluid 5 toward the opening 34. In one embodiment, the inner wall 78 has at least one of a circular shape and a parabolic shape. FIG. 11 shows an embodiment of an inner wall 79 that narrows slightly near the exit of the inner shaft 36. Further, in some embodiments, the shaft 36 is adjacent to the opening 34. The opening widens slightly where it meets the top surface of the base. This allows the protrusions 90 to open more easily and more easily when closing the flip-top lid 18. In yet another embodiment, as shown in FIG. 8 has a straight portion in a substantially vertical direction, and then has an angle that directs the fluid 5 toward the opening 34. 13 is similar to the inner shaft 36 of FIG. 12, but further includes the same components as described above. As mentioned above, the sudden movement of the cutting blade 60 or the inner shaft 36 assists in interrupting the dispensing of the fluid 5. Other examples of cutting blade configurations or internal protrusions around the opening are shown in Figures 14 and 15. 5. FIG. 14 shows a slightly downward facing opening rather than a horizontally extending shelf. While the opening 134 is shown with a cutting blade 160 that is angled on the inside, the above-mentioned figures 13 has a cutting blade 60 that includes a downward angled portion but extends horizontally. 15 also shows a cutting blade 2 with an inner surface angled away from the through opening. An opening 234 having a diameter of 60 is shown.

[0056] 16 and 17 show the shape of the surface of the container or dome outside the opening 34. For example, Figure 16 shows a joint where the central portion 30 meets the opening 34. As mentioned above, Figures 14 and 15 show the rounded edges around the opening at that location. 17 also shows a sloped wall surface between the central portion 30 and the opening 34. A depression 161 having a face is shown.

[0057] The bottle 10 and closure cap 18 can be produced in a number of different ways. In one exemplary approach, a method for manufacturing or producing a filled bottle for dispensing a fluid is provided. The method includes the steps of molding a receptacle, such as a container body, having a threaded neck; filling the reservoir with a fluid, such as a thixotropic fluid; forming a closure cap having a disc and a flip-top lid; and closing the filled receptacle with the closure cap. The tank can be formed and filled in-line, or formed in one location and filled in another. Can be filled in place.

[0058] In one approach, the closure cap and disk are molded separately and are then attached to each other. In some embodiments, the molded base includes an inner skirt and and an outer skirt, the inner skirt having a base thread disposed thereon, the base thread The preformed base is configured to engage threads on the neck of the receiver. The base may include one or more retaining rings on the inner skirt (located a short distance from the threads). a central dome-shaped portion having an opening, the opening being on the side of the central dome-shaped portion; the central dome-shaped portion aligned with an inner shaft terminating in a non-planar end surface opposite the central dome-shaped portion; As described above, the opening in the base, when the opening is not blocked, In some embodiments, the shaped container is configured to allow fluid to flow out of the opening. The flip-top lid has an internal protrusion movable between a first position and a second position, The protrusion prevents the fluid from flowing out of the container body when the protrusion is in the first position. and the second position blocks the opening in the base so that the fluid is prevented from flowing through the opening in the base. allows the flow to flow out.

[0059] As mentioned above, the closure cap and disk may be used in some approaches to the closure. The mouth cap and disc are molded separately and then secured or snapped together. In this embodiment, the manufacturing method further includes: The assembly step is to orient the cap or base 20 in a specific position relative to the rest of the base. The disc may be fitted with one or more screws before being assembled to the rest of the closure cap. By providing a further orientation step, the assembled cap Furthermore, in some configurations, the flow rate is more likely to be constant. The constant flow rate does not require structural changes, and some elements of the closure cap or disc may be By adjusting the relative positioning, it can be adjusted for different fluids. One approach is to use a closure cap or a disk, or both. Visible marks or engraved notches are used to determine the relative positioning of the disc and / or closure cap. can be subsidized.

[0060] This may depend, in part, on the form of those various elements. 5, the non-linear end surface 38 of the inner shaft 36 has three Along with having the cutouts, the disk 42 of FIG. 6 has four flanges 54. The fluid flow through the closed cap is directed to the cutting opening of the inner shaft 36. The orientation of the transducer 54 can affect the performance of the transducer. The element increases the flow rate between the two by requiring the fluid to travel a longer path to the bottle outlet. Relative orientation to promote animal flow or slow down fluid flow It is possible to adjust the fluid path or standardize the flow rate for multiple closure caps. In consideration of the benefits of the present invention, the method of manufacturing or assembling the closure cap and bottle is Orienting the mask in a particular manner relative to the remainder of the closure cap. This can be done.

[0061] As previously alluded to, the method for producing a filled bottle comprises attaching a disk to the closure cap. The molded disc may include snap-fitting the retaining ring onto the retaining ring. In some embodiments, the pinhole includes a central pinhole and a portion disposed around the central pinhole. After the disk is attached to the rest of the closure cap 18, the skirt 42, the central portion of the base 20, the inner skirt 26, and the mixing chamber 56 and the plurality of The inner shaft 36 at the base that defines the fluid channel 58 is The inner shaft 36 is formed by a planar end surface and a disk 42. A channel 58 formed between the opening 34 and the mixing chamber 56 allows fluid to communicate with the opening 34. This allows the material to be advanced into a chute formed by an internal shaft 36.

[0062] The filled receptacle or container body may, in some configurations, be fitted with a lighter material associated with the closure cap. The fluid is sealed by a seal, e.g., a line of paperboard, plastic and / or metal material. A liner such as a liner is associated with a portion of the retaining ring, and a closure cap 18 is attached to the container. When threaded onto the body, the liner seals the fluid 5 within the container.

[0063] Additionally, in some approaches, the method of manufacturing the closure cap involves the use of a vein in a mold. forming a flip-top closure cap including a base and a flip-top lid. In some embodiments, the molded base is a dome-shaped wall, a wall having an opening therethrough and an internal shaft projecting from said wall; and an internal threaded member; a skirt and a flat portion and / or possibly a reinforcing rib connected to said inner skirt; The outer skirt is connected to the inner skirt, and a retaining ring is attached to the inner skirt. The inner shaft of the shaped base projects inwardly from the domed wall and has a non-planar end. The molded closure cap is further hingedly connected to the base. a flip-top lid having an internal protrusion, and The internal protrusion moves from a first position where the internal protrusion blocks the opening to a second position where the internal protrusion does not block the opening of the base. In some embodiments, the method for manufacturing the closure cap further comprises: Snap-fitting the disk into a retaining ring or protrusion on the base. In some embodiments, the disk has a central pinhole and a a partial annular slot disposed around the base and projecting toward the base when installed. and a flange disposed between the inner shaft and the partial annular slot. After the disk and base are attached, the disk, the domed wall, and the inner skirt are and a mixing chamber is formed between the inner shaft, wherein a plurality of fluid channels are provided in the front and rear ends of the mixing chamber. A non-planar end surface of the inner shaft and the disk define a recess.

[0064] In some embodiments, the closure cap comprises a flip-top cap and a disk. Made from only two separate components, including a single flip-top cap The base and flip-top lid are formed as an integrated, one-piece structure. The two separate components (i.e., flip-top cap and disc) are The closure cap is formed and assembled from a single material. After ejection, the disc is attached to the closing cap (the base and flip-top lid). (which can be formed in the same mold or at different locations) This assembly can be achieved, for example, by snapping the disk into place on the base. Additionally, the liner may be retained by the mechanism or other device. the liner may be attached to a sealing ring, the sealing ring sealing the fluid within the bottle. The base and flip-top lid may be attached to the disc in some configurations. In another embodiment, the disk is molded in the same mold as the base and flip-top lid. Furthermore, the base and the disk are molded separately in the same mold. In yet another embodiment, the closing cap may be molded separately and assembled. The entire cap (including the base, flip-top lid, and disc) is molded or pre-assembled together. You can do this.

[0065] As noted above, while remaining consistent with these teachings, Numerous adjustments can be made. For example, Figures 18 and 19 show a disk with an annular opening. As shown, the disk 342 extends vertically from the peripheral portion 386. a central portion 384 spaced a distance from the center of the periphery 386; and an annular opening 350 in the peripheral portion 386. In this configuration, the mixing chamber 356 is disposed on the inner shaft 356. The volume is designed to be somewhat independent of the volume of the discharge shaft or chamber formed by the In fact, the mixing chamber 356 may be designed to be as small as some of the other embodiments described above. The inner shaft 35 forms the discharge chamber from the mixing chamber 356. To allow for the flow of fluid 5 into the mixing chamber 6, the radius of the central portion 384 is set so that fluid 5 is An opening or openings formed between the inner shaft 336 and the mixing chamber 356 from the chamber 356 or an inner shaft 358 that provides clearance for passage through the fluid channel 358. 36 and / or the opening 358 may be large enough to accommodate the internal shell. A height disposed above the vertical portion of the disk 342 that may be disposed adjacent to the shaft 336. In short, the mixing chamber 356 The opening between the inner shaft 358 and the central portion 384 is significantly larger than the inner shaft. It can be moved or sized to allow fluid flow even when there is no Additionally, in Figures 18 and 19, the central portion 384 is shown as having no central pinhole. However, in some embodiments, the central portion 384 is formed through a pinhole or other structure. Further, the disk 342 may have a cap or the like. The ribs and / or protrusions may be integrated into the rest of the plate. Snap-fit between portions of the base or other complementary geometries between the disc and the base. 20 and 21 show other implementations of disk 442. An example is shown, in which there is no central pinhole 48 found in some of the other embodiments. 18 and 19, but does not have a flange as in the embodiment described above in FIGS. 18 and 19, but has a central portion 38 The vertical portion of the disc separating the 4 and peripheral portion 386 is aligned to allow for internal mixing of the product.

The exemplary shapes shown show openings with exemplary cutting blades, but these various shapes are not intended to be limiting. Other aperture shapes and configurations described herein may be incorporated.

[0069] As mentioned above, the mixing chambers described herein are designed to return the separated serum to the fluid. After incorporating or mixing, the fluid and / or a portion thereof is expelled through the opening in the container cap. In one approach, the desired size of the mixing chamber is determined in part by the volume of the mixture in the vessel. This may depend on the viscosity or other fluid properties of the fluid or product. The size of the mixing chamber 56 depends, in part, on the size of the inner shaft 36, as described above. , the location of the disk 42 according to the corresponding geometry of the base, and / or the shape of the disk. Briefly referring to Figures 33 and 34, two different sizes of mixed channels are 34. The components are similar, but the inner shaft 36 of FIG. The walls formed are longer than the walls of the shaft 36' in FIG. 33 and have a corresponding geometry (e.g. The retaining ring 44') is shaped to fit the corresponding geometry of the base 20 (e.g., retaining ring 44) and the center The base 20' is positioned at a greater distance from the central surface 30' than the central surface 30. As shown, the relative sizes of these components can vary; The function is maintained, i.e. the mixing chamber is such that the separated serum is mixed with the rest of the fluid product 5. This helps prevent leakage from the bottle separately from the other parts.

[0070] As mentioned above, the inner wall 78 of the inner shaft may be, for example, circular or elliptical, among others. Furthermore, the inner wall 78 may have a cross section of various different shapes. The shape or configuration of the casing can be various. For example, the casing shown in FIGS. Thus, the inner shaft 36, 136, 236 is approximately linear along the height of the inner shaft 36. In other embodiments, the inner shaft 36 may have a non-contoured inner wall 78. It may have one or more linear interior walls 78. 35 shows the inner wall 878 of the inner shaft 836 angled toward the opening 834. In this approach, the downward angle gives the cross section a V-shaped configuration. 36 shows an inner shaft having an inner wall 978 with a slightly non-linear downward slope. 936. One approach is to consider this downward slope as giving the cross section a modified U-shape. In another embodiment, FIG. 37 shows an inner wall having a stepped configuration with a gradually narrowing diameter. An inner shaft 1036 having a 1078 is shown.
