PIERCING NOZZLE SYSTEM, DEVICE AND METHOD

BACKGROUND
Technical Field

The present technology relates to a piercing nozzle system, device and method for use in connection with controllably dispensing material from a chub or sausage package and more specifically to methods and apparatuses related to hand-held caulking guns that can pierce the sausage package. The present technology can further relate to an adapter system for use in connection with a dispensing device for dispensing material from the sausage package.

Background Description

Material dispensing systems are desirable for providing an ergonomic hand-held device controllably dispensing a material with a desired bead size and shape. The use of caulking or sealing materials to fill gaps between constructions is known. The caulking materials can be utilized indoors and outdoors, and can further be paintable to seamlessly blend between the constructions. There are many different types of caulking materials, along with different types of systems to dispense them.

Squeezable packaging with a nozzle top can be employed to store and then dispense the caulking material. These types of packaging's typically hold a small amount of material, and controlling the dispensing of the material can be difficult.

Hand-held material dispensing devices, such as caulking guns, are well known and generally rely on the action of a piston to push caulk material out of a caulk tube. The motion of the piston is induced by the advancement of a piston rod in the direction of the caulk tube, with the piston rod being advanced in the direction of travel by the operator's squeezing of a trigger.

These known devices are designed to receive and carry a disposable caulk tube. The housing of these caulking guns and the trigger are generally formed of stamped metal plate for manufacturing economy. The caulk tube generally includes a rigid cylindrical tube featuring a sliding piston (plunger), and a nozzle tip, with material stored inside the tube. The caulk tube is commonly more expensive to manufacture than a sausage package because of the different structural elements. While a sausage package is considerably less expensive and easier to manufacture since it is a type of container formed by a tube of flexible packaging material crimped at the ends after filling.

To overcome the disadvantages of caulking tubes, manufacturers developed so called “sausage package” or “chub packs” for the sealant compositions. Sausage packages use less material for the manufacture of the package as compared to caulking tubes, and can be made to be impermeable to air and moisture. They also take up less space in the case package. This allows for a sealant composition stored therein to maintain its consistency and usability and reduce curing of the material. Overall, this leads to less waste in both packaging and in preservation of the product in the packaging.

While the above-described devices fulfill their respective, particular objectives and requirements, the aforementioned devices or systems do not describe a piercing nozzle system or device that allows controllably dispensing material from a sausage package.

A need exists for a new and novel piercing nozzle system or device system that can be used for controllably dispensing material from a sausage package. In this regard, the present technology substantially fulfills this need. In this respect, the piercing nozzle system or device according to the present technology substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of controllably dispensing material from a sausage package.

DETAILED DESCRIPTION OF THE EMBODIMENTS

In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular embodiments, procedures, techniques, etc. in order to provide a thorough understanding of the present technology. However, it will be apparent to one skilled in the art that the present technology may be practiced in other embodiments that depart from these specific details.

Referring now to the drawings, and particularly to FIGS. 1-17, an embodiment of the piercing nozzle system, device and method of the present technology is shown and generally designated by the reference numeral 10.

In FIGS. 1 and 2, a new and novel sausage package dispensing system or device 10 of the present technology for controllably dispensing material from a collapsible package or sausage package 2 is illustrated and will be described. More particularly, the sausage package dispensing system 10 can be associated with a sausage dispensing device 12 configured to receive a collapsible package or sausage package 2, a package tube 28, a piercing nozzle 30, 80, 170 and a plunger 140. The package tube 28, the piercing nozzle 30, 80, 170, and the plunger 140 can be provided together as an adapter system to the dispensing device 12, or can be provided separately, or can be provided with the dispensing device 12 as a single unit.

In some embodiments, the sausage package 2 can include any cylindrically shaped or sausage-shaped casing package that is collapsible and contains an extrudable material therein. In the exemplary the extrudable material can be, but not limited to, a sealant, grease, a lubricant, food materials, a caulking, a paste, mixable compounds, a filler, and the like.

Many advantages come with packaging adhesive and sealant products in the sausage package 2. A first advantage is that the sausage package 2 itself represents an initial cost savings compared to a conventional cartridge or tubes in manufacturing. As the cost in manufacturing the sausage package is substantially less than manufacturing a conventional cartridge or tube.

Another advantage is the extended shelf life of the material in the sausage package 2. Sausage packaging uses a flat film that is then formed into a sausage and clipped or sealed with product material stored therein. As a result, no air is introduced during the filling process. The film used to form the sausage package 2 also provides an excellent moisture barrier, such as multi-layered film with a trapped aluminum.

Still another advantage is the increased space savings for storing in warehouses, on store shelves, during transportation or carrying by a user to a job site or location.

Another key benefit of the sausage package 2 is lower disposal costs. Since an empty sausage package is basically a small, compressed, foil disc that is 10% the size of a typical empty cartridge or tube, disposal cost savings can be high. In addition, the sausage package 2 can result in less waste going to the landfill, which is a key component in environmental sustainability.

The present technology provides efficient dispensing of the material in the sausage package 2 by utilizing aftermarket components that can be easily used with existing caulking guns or can be an all-in-one caulking gun or dispensing device including the components of the present technology.

For exemplary purposes, the sausage dispensing device 12 can have a configuration similar to a gun featuring a main housing 14, a plunger rod 16, an internal cavity featuring reinforcing ribs 18, and a dispensing end section 20. A hand grip, a trigger and a piston grip can be utilized with the dispensing device 12. In some embodiments, the plunger rod 16 of the dispensing device 12 can be manually driven via a rack or ratcheting system or via a motor and gear system. The main housing 14 can be made of, but not limited to, plastic, metal, composite, an alloy, or any combination thereof. The dispensing device 12 can be a single molded unit or can be made of separable and attachable sections secured together by, but not limited to, adhesive, welding, fasteners, tabs, locks, clips, or other securing means.

The internal cavity of the main housing 14 can be configured to receive the sausage package 2 directly or receive the package tube 28 with the sausage package 2 located inside the package tube 28. Reinforcing ribs 18 can be configured to provide rigidity to the dispensing device 12, to support the package tube 28 received in the main housing 14 and/or to assisting in containing or guiding the sausage package 2 while contained in the internal cavity.

The package tube 28 can be a hollow tube with opposite open ends thereby allowing reception of the sausage package 2 inside the package tube 28 from either end. A width or diameter of the package tube 28 can be sized to be received in a caulking gun or the internal cavity of the main housing 14 of the dispensing device 12. The package tube 28 can be made out of any suitable material such as, but not limited to, plastic, metal, alloys, cardboard, and the like. Further, the package tube 28 can be transparent or include a window or opening to easily view the sausage package 2 inside the package tube 28. In some embodiments, the package tube 28 can include ribs or grooves to increase rigidity of the package tube 28 and/or to prevent bending or expansion of the package tube 28 during use.

The plunger 140 can be configured to be attachable to the plunger rod 16 or a part associated therewith, and can be further configured to be slidably raceable within the package tube 28. Alternatively, the plunger 140 can be configured to be slidably receivable along a longitudinal axis of the internal cavity of the main housing 14 so that it can be used without the package tube 28.

The dispensing end section 20 can be configured to receive the piercing nozzle 30, 80, 170 therein so that at a male portion 70, 130 of the piercing nozzle 30, 80, 170 can be inserted through a dispensing end opening 22 defined through the dispensing end section 20 of the dispensing device 12.

A nozzle tip 160 can be attachable to the male portion 70, 130 of the piercing nozzle 30, 80 thereby securing the piercing nozzle 30, 80 to the dispensing end section 20, as best illustrated in FIG. 2. The nozzle tip 160 can be configured to assist in dispensing and/or spreading material dispensed from the sausage package 2 onto a surface or into a gap. The nozzle tip 160 can be made of, but not limited to, plastic, metal, composite, an alloy, or any combination thereof.

With reference to FIGS. 3-7, an embodiment of the piercing nozzle 30 is illustrated and will be described. The piercing nozzle 30 can be removably attachable to or integrally formed with the dispensing end section 20. The piercing nozzle 30 can include a housing featuring a nozzle sidewall 32 defining a nozzle cavity 34 therein configured to receive an end of the sausage package 2. The piercing nozzle 30 can be made of, but not limited to, plastic, metal, composite, an alloy, or any combination thereof.

A width or diameter of the sidewall 32 can be substantially the same as the width or diameter of the package tube 28, so that they contact each other during use and allowing the end of the sausage package 2 to easily travel through the open end of the package tube 28 and into the nozzle cavity 34. Alternatively, the width or diameter of the sidewall 32 can be greater than the width or diameter of the package tube 28 thereby allowing either end of the package tube 28 to be received in the nozzle cavity 34. In another alternative, the width or diameter of the sidewall 32 can be less than the width or diameter of the package tube 28 thereby allowing the sidewall 32 portion of the piercing nozzle 30 to be received in at least a portion of the hollow interior of the package tube 28.

A ledge 36 can extend from a perimeter of the nozzle sidewall 32 at a location where the nozzle sidewall 32 transitions to a nozzle end wall 38. The ledge 36 can have a width or diameter greater than nozzle sidewall 32. The ledge 36 can be configured to prevent the piercing nozzle 30 from being completely inserted into the hollow interior of the package tube 28.

An angled or curved section 40 can transition from the ledge 36 to the nozzle end wall 38. The section 40 can be indented toward the nozzle cavity 34, thereby creating a recessed space in relation to the ledge 36 and the nozzle end wall 38. A nozzle opening 41 can be centrally defined through the nozzle end wall 38 and configured to allow material from the sausage package 2 to pass therethrough.

The male portion 70 can extend from the nozzle end wall 38 in a direction away from the nozzle sidewall 32. The male portion 70 can defined a longitudinal male portion bore 72 therethrough, and can include external threads 74. The male portion bore 72 is in direct fluid communication with the nozzle opening 41, thereby allowing material from the sausage package 2 to be received from the nozzle opening 41 and exit the male portion 70. Further, the male portion bore 72 can convergingly taper in a direction toward the nozzle end wall 38 so that a first width or diameter of the male portion bore 72 adjacent the nozzle opening 41 is less than a second width or diameter of an exit end of the male portion bore 72 opposite the nozzle opening 41.

In some embodiments, the male portion 70 can be integrally formed with and extending out from the dispensing end section 20.

A width or diameter of the male portion 70 including the external threads 74 can be configured to be inserted through the dispensing end opening 22, as best illustrated in FIG. 7. In some embodiments, the dispensing end opening 22 is configured to prevent the housing of the piercing nozzle 30 from passing therethrough. When the piercing nozzle 30 is assembled in the dispensing end section 20, the ledge 36 and/or the nozzle end wall 38 can abut or contact an end wall of the dispensing end section 20 that includes the dispensing end opening 22.

The nozzle tip 160 can include an attachment end configured to secure the nozzle tip 160 to the male portion 70. This can be accomplished, but not limited to, by utilizing internal threads of the nozzle tip 160 that are engageable with the external threads 74 of the male portion 70. In some embodiments, other securing mechanisms can be utilized instead of threads such as, but not limited to, ratchets, clips, latches, locks, or magnets. The width or diameter of the attachment end of the nozzle tip 160 can be greater than the dispensing end opening 22, thereby clamping the piercing nozzle 30 to the end wall of the dispensing end section 20 when the nozzle tip 160 is secured to the male portion 70.

One or more recessed members 42 can extend from the nozzle end wall 38 and/or the curved section 40 and into the nozzle cavity 34. The recessed members 42 can include a recessed member end wall 44, recessed member sidewalls 46 and a recessed member bottom wall 48, thereby defining a recessed cavity. The recessed cavity can in part be further defined by the nozzle sidewall 32 of the housing, as best illustrated in FIGS. 3 and 6. In the exemplary, the piercing nozzle 30 can include two recessed members 42 located opposite each other with the male portion 70 located therebetween. In some embodiments, any number of recessed members 42 can be utilized with the present technology.

One or more piercing projections 50, as best illustrated in FIGS. 4-7, can extend from the recessed member sidewalls 46 and/or the recessed member bottom wall 48 of each of the recessed members 42 and into the nozzle cavity 34. In the exemplary, the piercing projections 50 can include two or more piercing walls 52 that extend from the recessed member sidewalls 46 and/or the recessed member bottom wall 48. The piercing walls 52 can be at an angular orientation with each other forming a generally V-shape when viewing into the nozzle cavity 34. An internal angle between the piercing walls 52 can be less than 180°. Further, the converging angle of each of the piercing projections 50 can be facing each other so that an opened portion of the V-shape faces the nozzle sidewall 32.

Each of the piercing walls 52 can include an angled edge 54 that converge toward each other to form a piercing tip 56 of the piercing projections 50. The piercing tip 56 can be configured to easily pierce or puncture a casing of the sausage package 2 when pressed thereagainst.

In the exemplary, the recessed members 42 and/or the piercing projections 50 can be configured to not extend into or obstruct the longitudinal male portion bore 72 of the male portion 70, thereby creating a clear path for material to pass or travel through.

An internal rib 60 can extend between the piercing projections 50 passing over the nozzle opening 41. The internal rib 60 can include a middle portion 62 that extends over the nozzle opening 41, thereby dividing the nozzle opening 41 into two opposite areas. The internal rib 60 can further include a piercing projection portion 64 that extends at an angle from opposite ends of the middle portion 62 toward the piercing tip 56 of each of the piercing projections 50. The piercing projection portion 64 can meet the piercing projections 50 either directly at the piercing tip 56, or adjacent thereto or offset therefrom to make a separation from the piercing tip 56, as best illustrated in FIG. 6. This separation can be configured to assist in separating a pierced portion of the casing of the sausage package 2 away from the remaining portion of the sausage package 2. Such a separation can allow for the creation of a larger pierced opening in the sausage package 2, thereby providing easier flow of material out from the sausage package 2 when the dispensing device 12 is operated.

At least one channel can be defined along a longitudinal axis of each of the piercing projections 50 and/or the piercing projection portion 64 of the internal rib 60. Further, the channel can be defined as the open area between each of the piercing walls 52 and the piercing projection portion 64. The channel can be in communication with the nozzle opening 41. Once the sausage package 2 is punctured by the piercing projections 50, the piercing projections 50 are inserted/received into the interior of the sausage package 2 so that any material in the sausage package 2 is allowed to flow through the channel and into the nozzle opening 41, and then into the male portion bore 72.

The internal rib 60 can further provide structural support for the piercing nozzle 30 and/or resist against collapsing of the nozzle sidewall 32. Still further, the internal rib 60 can assist in guiding the end of the sausage package 2 toward the piercing projections 50 and/or preventing the pierced portion of the casing of the sausage package 2 from entering or obstructing the nozzle opening 41 and/or the male portion bore 72, as best illustrated in FIG. 7 with the flow of material being represented by arrows.

In some embodiments, the nozzle sidewall 32, the piercing projections 50, the internal rib 60 and the male portion 70 can be integrally formed to create the piercing nozzle 30.

With reference to FIGS. 8-12, an embodiment of the piercing nozzle 80 is illustrated and will be described, which is similar to the embodiment illustrated in FIGS. 3-7 and as described above. The piercing nozzle 80 can be removably attachable to or integrally formed with the dispensing end section 20. The piercing nozzle 80 can include a housing featuring a nozzle sidewall 82 defining a nozzle cavity 84 therein configured to receive an end of the sausage package 2. The piercing nozzle 80 can be made of, but not limited to, plastic, metal, composite, an alloy, or any combination thereof.

A width or diameter of the sidewall 82 can be substantially the same as the width or diameter of the package tube 28, so that they contact each other during use and allowing the end of the sausage package 2 to easily travel through the open end of the package tube 28 and into the nozzle cavity 84. Alternatively, the width or diameter of the sidewall 82 can be greater than the width or diameter of the package tube 28 thereby allowing either end of the package tube 28 to be received in the nozzle cavity 84. In another alternative, the width or diameter of the sidewall 82 can be less than the width or diameter of the package tube 28 thereby allowing the sidewall 82 portion of the piercing nozzle 80 to be received in at least a portion of the hollow interior of the package tube 28.

A ledge 86 can extend from a perimeter of the nozzle sidewall 82 at a location where the nozzle sidewall 82 transitions to a nozzle end wall 88. The ledge 86 can have a width or diameter greater than nozzle sidewall 82. The ledge 86 can be configured to prevent the piercing nozzle 80 from being completely inserted into the hollow interior of the package tube 28.

The nozzle end wall 88 can be planar extending to the ledge 86. A nozzle opening 89 can be centrally defined through the nozzle end wall 88 and configured to allow material from the sausage package 2 to pass therethrough.

The male portion 130 can extend from the nozzle end wall 88 in a direction away from the nozzle sidewall 82. The male portion 130 can defined a longitudinal male portion bore 132 therethrough, and can include external threads 134. The male portion bore 132 is in direct fluid communication with the nozzle opening 89, thereby allowing material from the sausage package 2 to be received from the nozzle opening 89 and exit the male portion 130. Further, the male portion bore 132 can convergingly taper in a direction toward the nozzle end wall 88 so that a first width or diameter of the male portion bore 132 adjacent the nozzle opening 89 is less than a second width or diameter of an exit end of the male portion bore 132 opposite the nozzle opening 89.

A width or diameter of the male portion 130 including the external threads 134 can be configured to be inserted through the dispensing end opening 22, as best illustrated in FIG. 12. In some embodiments, the dispensing end opening 22 is configured to prevent the housing of the piercing nozzle 80 from passing therethrough. When the piercing nozzle 80 is assembled in the dispensing end section 20, the ledge 86 and/or the nozzle end wall 88 can abut or contact an end wall of the dispensing end section 20 that includes the dispensing end opening 22.

The nozzle tip 160 can include an attachment end configured to secure the nozzle tip 160 to the male portion 130. This can be accomplished, but not limited to, by utilizing internal threads of the nozzle tip 160 that are engageable with the external threads 134 of the male portion 130. In some embodiments, other securing mechanisms can be utilized instead of threads such as, but not limited to, ratchets, clips, latches, locks, or magnets. The width or diameter of the attachment end of the nozzle tip 160 can be greater than the dispensing end opening 22, thereby clamping the piercing nozzle 80 to the end wall of the dispensing end section 20 when the nozzle tip 160 is secured to the male portion 130.

One or more recessed members 90 can extend from the nozzle end wall 88 and into the nozzle cavity 84. The recessed members 90 can include opposed recessed member sidewalls 92, opposed recessed member end walls 94 and a recessed member bottom wall 96, thereby defining a recessed cavity. The recessed members 90 can be offset from the nozzle sidewall 82 to provide a portion of the nozzle end wall 88 between the recessed members 90 and the ledge 86, as best illustrated in FIG. 8. In the exemplary, the piercing nozzle 80 can include two recessed members 90 located opposite each other with the male portion 130 located therebetween. In some embodiments, any number of recessed members 90 can be utilized with the present technology.

One or more piercing projections 100, as best illustrated in FIGS. 9-12, can extend from one of the recessed member sidewalls 92, one or more of the recessed member end walls 94 and/or the recessed member bottom wall 96 of each of the recessed members 90 and into the nozzle cavity 84. In the exemplary, the piercing projections 100 can include a two or more piercing walls 102 that extend from one of the recessed member sidewalls 92, one or more of the recessed member end walls 94 and/or the recessed member bottom wall 96. The piercing walls 102 can be at an angular orientation with each other forming a generally V-shape when viewing into the nozzle cavity 84. An internal angle between the piercing walls 52 can be less than 180°. Further, the converging angle of each of the piercing projections 100 can be facing each other so that an opened portion of the V-shape faces the nozzle sidewall 82.

Each of the piercing walls 102 can include an angled edge 104 that converge toward each other to form a piercing tip 106 of the piercing projections 100. The piercing tip 106 can be configured to easily pierce or puncture a casing of the sausage package 2 when pressed thereagainst.

In the exemplary, the recessed members 90 and/or the piercing projections 100 can be configured to not extend into or obstruct the longitudinal male portion bore 132 of the male portion 130, thereby creating a clear path for material to pass or travel through.

An internal rib 110 can extend between the piercing projections 100 passing over the nozzle opening 89. The internal rib 110 can include a central portion 112 that extends over the nozzle opening 89, thereby dividing the nozzle opening 89 into two opposite areas. The internal rib 110 can further include a piercing projection portion 114 that extends at an angle from opposite ends of the central portion 112 toward the piercing tip 106 of each of the piercing projections 100. The piercing projection portion 114 can meet the piercing projections 100 either directly at the piercing tip 106, or adjacent thereto or offset therefrom to make a separation from the piercing tip 106, as best illustrated in FIG. 11. This separation can be configured to assist in separating a pierced portion of the casing of the sausage package 2 away from the remaining portion of the sausage package 2. Such a separation can allow for the creation of a larger pierced opening in the sausage package 2, thereby providing easier flow of material out from the sausage package 2 when the dispensing device 12 is operated.

At least one channel can be defined along a longitudinal axis of each of the piercing projections 100 and/or the piercing projection portion 114 of the internal rib 110. Further, the channel can be defined as the open area between each of the piercing walls 102 and the piercing projection portion 114. The channel can be in communication with the nozzle opening 89. Once the sausage package 2 is punctured by the piercing projections 100, the piercing projections 100 are inserted/received into the interior of the sausage package 2 so that any material in the sausage package 2 is allowed to flow through the channel and into the nozzle opening 89, and then into the male portion bore 132.

The internal rib 110 can further provide structural support for the piercing nozzle 80 and/or resist against collapsing of the nozzle sidewall 82. Still further, the internal rib 110 can assist in guiding the end of the sausage package 2 toward the piercing projections 100 and/or preventing the pierced portion of the casing of the sausage package 2 from entering or obstructing the nozzle opening 89 and/or the male portion bore 132, as best illustrated in FIG. 7 with the flow of material being represented by arrows.

One or more secondary piercing members 120 can extend from the nozzle end wall 88 and/or the nozzle sidewall 82 into the nozzle cavity 84. The secondary piercing members 120 can be located in a spaced apart relationship between the recessed members 90 and/or between the piercing projections 100. The secondary piercing members 120 can each include an internal rib section 122 and a puncture tooth 124 pointing in a direction away from the nozzle end wall 88 and into the nozzle cavity 84. The secondary piercing members 120 can be configured to not obstruct the flow of material into the male portion bore 132.

The secondary piercing members 120 or any portion thereof can be configured to provide additional strength and/or rigidity to the piercing nozzle 80 during use. Collapsing of the nozzle sidewall 82 and/or the nozzle end wall 88 can be reduced by configuring a width, a height and/or a location of the internal rib section 122 or any portion of the secondary piercing members 120.

The puncture tooth 124 can have a first wall or edge extending at an angle from the internal rib section 122 and a second wall or edge 126 extending at an angle from the nozzle end wall 88, an area of the nozzle end wall 88 that in part defines the nozzle opening 89 or an end of the male portion 130 adjacent to the nozzle opening 89. The angle of the first edge and the second edge 126 converge to form the puncture tooth 124.

The puncture tooth 124 can be configured to further puncture the sausage package 2 in combination with the piercing tip 106 to create a larger opening in the sausage package 2, thereby allowing material to flow more easily from the sausage package 2, as best illustrated in FIG. 12

The piercing nozzle 80 can include any number of the secondary piercing members 120 radially arranged about a longitudinal axis of the piercing nozzle 80 or the male portion bore 132.

In some embodiments, the nozzle sidewall 82, the piercing projections 100, the internal rib 110, the secondary piercing members 120 and the male portion 130 can be integrally formed to create the piercing nozzle 80.

Referring to FIGS. 13-15, the plunger 140 of the sausage package dispensing system is illustrated and will be described. The plunger 140 can be attachable to the plunger rod 16 of the dispensing device 12. This can be accomplished utilizing an adapter 24 that is part of or is attached to the plunger rod 16, which then is configured to fit with or attached to the plunger 140. Movement of the plunger rod 16 translates into longitudinal movement of the plunger 140 within the hollow interior of the package tube 28 or the internal cavity of the dispensing device 12. The plunger 140 can be made of, but not limited to, plastic, metal, composite, an alloy, or any combination thereof.

The plunger 140 can include a pair of identical or similarly configured halves, with each half including a plunger sidewall 142 meeting at a radially arranged medial point 150 that further includes a plunger base wall 152 extending across the medial point 150 and therebetween thereby dividing the plunger 140 into two mirrored halves.

Each plunger sidewall 142 can include an exterior side 144 and an interior side 146, as best illustrated in the enlarged section of FIG. 15. Each half of the plunger 140 includes a plunger cavity 148 defined within the interior side 146 of the plunger sidewall 142 and the plunger base wall 152. The plunger cavity 148 can be configured to receive an end of the sausage package 2 therein.

A plurality of plunger protrusions 154 can extend from the plunger base wall 152 into the plunger cavity 148. The plunger protrusions 154 can be formed by a plurality of plunger protrusion walls 156 that extend away from the plunger base wall 152 in a generally geometrical shape. Each of the plunger protrusions 154 can define its own internal cavity defined by the plunger protrusion walls 156 and the plunger base wall 152 or one or more of the plunger protrusion walls 156, the plunger base wall 152 and the plunger sidewall 142. In some embodiments, some of the plunger protrusions 154 defined in part by the plunger sidewall 142 can have a geometric shape different to that of the plunger protrusions 154 defined by only the plunger protrusion walls 156 and the plunger base wall 152.

The geometric shape of the plunger protrusions 154 can be, but not limited to, square, triangle, circular, oval, polygonal and the like.

The plunger protrusion walls 156 can have a height or length extending from the plunger base wall 152 less than a height or length of the plunger sidewall 142 for that particular half of the plunger 140. This difference in height or length can further in part define the plunger cavity 148. In some embodiments, the one or more plunger protrusion walls 156 can have a height or length different to that of other plunger protrusion walls 156.

Referring to FIG. 15, the exterior side 144 of the plunger sidewall 142 can be angle θ in relation to a longitudinal axis of the plunger 140 or the medial point 150. This angle θ can result in a free end or edge of the plunger sidewall 142 to have a thickness less than a thickness near or at the medial point 150. The angle θ can assist in insertion of the plunger 140 into and out of the open end of the package tube 28 and/or into the nozzle cavity 34, 84 of the piercing nozzle 30, 80. Further, the angle θ can assist in the longitudinal travel of the plunger 140 through the hollow interior of the package tube 28 and/or across the reinforcing ribs 18 of the dispensing device 12 if the package tube 28 is not utilized. During travel of the plunger 140 through the package tube 28, the medial point 150 can contact the interior surface of the package tube 28 thereby acting as a sliding seal thereagainst to prevent seepage of material past the plunger 140.

An interior side of the nozzle sidewall 32, 82 that defines the nozzle cavity 34, 84 can be angled to complement the angle θ of the exterior side 144 of the plunger sidewall 142. This complementary angle allows for either side or half of the plunger 140 to be fully receivable in the nozzle cavity 34, 84.

The interior side 146 of the plunger sidewall 142 can be parallel with the longitudinal axis of the plunger 140 or can be angled so that a width or diameter of the plunger cavity 148 at the free end of the plunger 140 is less than a width or diameter of the plunger cavity 148 adjacent the plunger protrusions 154. The angle of the interior side 146 can be configured to assist in insertion of the end of the sausage package 2 into the plunger cavity 148 when the plunger 140 is pressed against that end of the sausage package 2.

The plunger protrusions 154 can be configured to provide rigidity to the plunger 140 and/or air pockets to prevent a vacuum lock against the end of the sausage package 2. The air pockets can be utilized for easy removal of the sausage package 2 from the plunger cavity 148 or withdrawal of the plunger 140 away from the sausage package 2.

Further, the adapter 24 attached to the end of the plunger rod 16 can include an exterior side featuring male protrusions 26 that are configured to be received in an open space defined in the plunger protrusions 154 of the plunger 140, as best illustrated in FIG. 15. This arrangement can be configured to provide a press or friction fit of the plunger 140 to the adapter 24, allowing for removal and/or replacement of the plunger 140. Alternatively, the protrusions 26 can be omitted from the adapter 24 so that a planar or flat exterior side of the adapter 24 contacts the plunger protrusions 154, as best illustrated in FIG. 16.

In some embodiments, the dispensing device 12 of the present technology can include a draw back system (not shown) to ensure bead flow or flow of the material from the sausage package 2 ceases activation of the plunger rod 16 is ceased. The drawback system can have a configuration capable of drawing back of pressure to avoid unwanted flow of material out the piercing nozzle 30,80, 170 or the nozzle tip 160. The draw back system can include, but not limited to: a biasing assembly which is capable of pushing back against a part of the packaging compression assembly or against the sausage package 2; a retraction assembly which is capable of retracting at least a portion of the packaging compression assembly or the sausage package 2; or a nozzle tip moving assembly which is capable of moving the piercing nozzle 30,80, 170 away from the sausage package 2.

Referring to FIGS. 16 and 17, it can now be understood that the sausage package dispensing system 10 of the present technology can be used to dispense a material, such as but not limited, caulk, adhesive, sealant, paste, cement, and the like, from a sausage package 2. In exemplary use, a user can insert the sausage package 2 inside the package tube 28. The plunger 140 can be attached to the plunger rod 16 or the adapter 24, if not already part thereof. With the plunger rod 16 retracted, access to the internal cavity of the dispensing device 12 is allowed, and the piercing nozzle 30, 80 can be inserted into the dispensing end section 20 so that the male portion 70, 130 is received through dispensing end opening 22 of the dispensing end section 20.

The nozzle tip 160 can then be fitted with the male portion 70, 130 so that the piercing nozzle 30, 80 is clamped or secured to the dispensing end section 20.

While the plunger rod 16 is retracted, the sausage package 2 or the package tube 28 with the sausage package 2 therein can be inserted into the internal cavity of the dispensing device 12 so that a first end of the sausage package 2 is received in the nozzle cavity 34, 84 of the piercing nozzle 30, 80 or one of the open ends of the package tube 28 is adjacent the nozzle cavity 34, 84.

In some embodiments, the piercing nozzle 30, 80 can be inserted into the interior space of the main housing 14 first, and after which the sausage package 2 or the package tube 28 with the sausage package 2 therein can be inserted into the interior space of the main housing 14 so that the first end of the sausage package 2 is receivable in the nozzle cavity 34,84 of the piercing nozzle 30, 80.

With the piercing nozzle 30, 80 and sausage package 2 or the package tube 28 with the sausage package 2 therein installed in the interior space of the main housing 14, the user can then operate the dispensing device 12 to advance the plunger rod 16 which advances the plunger 140 toward a second end of the sausage package 2.

Operation of the dispensing device 12 advances the plunger 140 into the hollow interior of the package tube 28 so that a free end of the plunger 140 contacts the second end of the sausage package 2 so that the second end of the sausage package 2 is received in the plunger cavity 148 of the plunger 140. The second end of the sausage package 2 can be in contact with the plunger protrusions 154 extending into the plunger cavity 148. In some embodiments, the angle θ associated with both halves of the plunger 140 allows for easy insertion of the plunger through the open end and into the hollow interior of the package tube 28. It can be further appreciated that the angle θ can act as an insertion guide of the plunger 140 into the package tube 28.

Continued operation of the dispensing device 12 further advances the plunger 140 and pushes the sausage package 2 through the hollow interior of the package tube 28 so that a first end of the sausage package 2 is received in the nozzle cavity 34, 84 and pressed against the piercing projections 50, 100. This advancement of the sausage package 2 by the plunger 140 allows for the piercing tip 56, 106 to puncture through the first end of the sausage package 2, thereby opening a passage between the interior of the sausage package 2 and the nozzle cavity 34, 84 and the nozzle opening 41, 89 of the piercing nozzle 30, 80.

Further continued advancement of the plunger 140 by the plunger rod 16 through the hollow interior of the package tube 28 and against the second end of the sausage package 2 could expand the sidewalls of the sausage package 2. However, the package tube 28 is configured to contain any radial or outward expansion of the sausage package 2. Further, expansion of the package tube 28 can be contained by the reinforcing ribs 18 of the main housing 14.

During advancement of the plunger 140 through the hollow interior of the package tube 28, it can be appreciated that the medial point 150 of the plunger 140 can act as a radially or perimeter seal against the interior side of the package tube 28 that defines its hollow interior. This contact provided by the medial point 150 prevents seepage of material from the sausage package 2 past the plunger 140, as best illustrated in FIG. 17. Accordingly, reducing waste of the material and providing an efficient pushing force to extrude the material from the sausage package 2. In some embodiments, the plunger 140 can be utilized in either direction due to its mirrored structural nature.

This continued advancement of the plunger 140 can force the material out of the sausage package 2, over through the piercing projections 50, 100 and over the internal rib 60, 110, and then through the nozzle opening 41, 89 of the piercing nozzle 30, 80. The material can then be forced through the hollow interior of the nozzle tip 160 and dispensed out an opening defined or cut in a dispensing end of the nozzle tip 160.

In the exemplary, the user can visually determine the amount of material remaining in the sausage package 2 through the transparent package tube 28.

The sausage package 2 can be removed and replaced by operating the dispensing device 12 or the plunger rod 16 to withdraw the plunger 140 away from the piercing nozzle 30, 80. The user can then remove the sausage package 2 or the package tube 28 with the sausage package 2 therein from the internal cavity of the main housing 14. The emptied or used sausage package 2 can then easily be removed from the package tube 28 and discarded.

After which, the nozzle tip 160 can be removed from the male portion 70, 130 so that the piercing nozzle 30, 80 can be removed from the dispensing end section 20 for cleaning or replacement. Further, the plunger 140 can be removed from the plunger rod 16 or adapter 24 for cleaning or replacement.

With reference to FIGS. 18-24, an embodiment of the piercing nozzle 170 is illustrated and will be described, which is similar in function to and can substitute the piercing nozzle embodiments 30, 80 illustrated in FIGS. 3-12 and as described above. In the exemplary, the piercing nozzle 170 can be removably attachable to or integrally formed with the dispensing end section 20. The piercing nozzle 170 can include a housing featuring a nozzle sidewall 172 defining a nozzle cavity 174 herein configured to receive an end of the sausage package 2, a male member 180, a plurality of piercing members or projections 190 extending into the nozzle cavity 174, and a retaining wall 210. The piercing nozzle 170 can be made of, but not limited to, plastic, metal, composite, an alloy, or any combination thereof.

A width or diameter of the sidewall 172 can be substantially same as the width or diameter of the package tube 28, so that they contact each other during use and allowing the end of the sausage package 2 to easily travel through the open end of the package tube 28 and into the nozzle cavity 174. In some embodiments, the width or diameter of the sidewall 172 can be greater than the width or diameter of the package tube 28 thereby allowing either end of the package tube 28 to be received in the nozzle cavity 174. In other embodiments, the width or diameter of the sidewall 172 can be less than the width or diameter of the package tube 28 thereby allowing the sidewall 172 portion of the piercing nozzle 170 to be received in at least a portion of the hollow interior of the package tube 28, as best illustrated in FIG. 25 in the exemplary.

In yet some other embodiments, an exterior surface of the sidewall 172 can include threading, tabs, latches, detects, locks or any other mechanical fastening means that engage with an interior surface or a free end of the package tube 28. This configuration allows the nozzle 170 to be directly attached to the package tube 28 for operation thereof and receipt of the material of the sausage package 2 contained in the package tube 28.

A ledge 176 can extend from a perimeter of the nozzle sidewall 172 at a location where the nozzle sidewall 172 transitions to a nozzle end wall 178. The ledge 176 can have a width or diameter greater than nozzle sidewall 172. The ledge 176 can be configured to prevent the piercing nozzle 170 from being completely inserted into the hollow interior of the package tube 28 and/or to provide an abutment surface for the nozzle inside the dispensing end section 20 when assembled therewith or in operation in dispensing material.

As best illustrated in FIG. 23, the sidewall 172 can extend from the nozzle end wall 178 and can include an exterior surface parallel with or at an angle θ2 in relation to the longitudinal axis of the nozzle 170. This angle θ2 can result in a free end or edge of the nozzle sidewall 172 to have a thickness less than a thickness near a location adjacent to the nozzle end wall 178. The angle θ2 can assist in insertion of the nozzle 170 into the open end of the dispensing end section 20 or the package tube 28, thereby providing a friction fit, as best illustrated in FIG. 25.

In combination with exterior surface or in the alternative, the sidewall 172 can include an interior surface that defines the nozzle cavity 174 that is parallel with the longitudinal axis of the nozzle 170 or at an angle θ3 in relation to the longitudinal axis of the nozzle 170. This angle θ3 can result in the free end or edge of the nozzle sidewall 172 to have a thickness less than a thickness near the location adjacent to the nozzle end wall 178. The angle θ3 can assist in reception or insertion of the open end section of the package tube 28, thereby providing a friction fit. The angle θ3 can be the same or different to that of angle θ2.

The male member 180 can extend from the nozzle end wall 178 in a direction away from or opposite to the nozzle sidewall 172. The male member 180 can include a first section 182 and a second section 186. The first section 182 can extend from the nozzle end wall 178 in the direction away from or opposite to the sidewall 172, and the second section 186 can extend from an end of the first section 182. An offset from the second section 186 and the nozzle end wall 178 is created by a length of the first section 182. In some embodiments, various lengths of the first section 182 are within the scope of the present technology to accommodate different types of sausage dispensing devices and/or to allow a predetermined travel time of the material through the male member 180.

A first section bore 184 can be defined in or through the first section 182, and can be in direct fluid communication with the nozzle cavity 174, thereby allowing material from the sausage package 2 to be received, travel and exit the first section 182. Further, an interior surface of the first section 182 that defines the first section bore 184 can convergingly taper in a direction away from the nozzle end wall 178 at a first section angle θ4 so that a first width or diameter of the first portion bore 132 adjacent the nozzle end wall 178 is greater than a second width or diameter of the end of the first section 182 opposite the nozzle end wall 178.

The second section 186 can have a width or diameter less than the first section 182, thereby creating an edge or transition section 185. The transition section 185 can act as a stop edge for attachment of the nozzle tip 160. In some embodiments, the transition section 185 and its narrower width or diameter than that of the first section bore 184 can block, catch, and/or prevent any end wall material from the pierced sausage package 2 from entering and clogging the second section bore 188. In yet other embodiments an internal rib (not shown) similar to the above-described internal rib 60, 110 can be formed or associated with the transition section 185 that extends laterally across the first section bore 184 or the second section bore 188. In still other embodiments, a screen, mesh, or filter (not shown) can be received in the first section bore 184 abutting against and juxtaposition with an internally formed ledge of the transition section 185. The screen, mesh or filter can be configured to prevent any pieces of the sausage package 2 or unwanted material from exiting the nozzle 170.

An external surface of the second section 186 can include threads 189 configured to removably secure the nozzle tip 160. This can be accomplished, but not limited to, by utilizing internal threads of the nozzle tip 160 that are engageable with the external threads 189 of the second section 186. In some embodiments, other securing mechanisms can be utilized instead of threads such as, but not limited to, ratchets, clips, latches, locks, or magnets. In yet another embodiment, the external surface of the second section 186 can be smooth and configured for a friction fit with an internal surface of the nozzle tip 160.

A second section bore 188 can be defined through the second section 186, and can be in direct fluid communication with the first section bore 184, thereby allowing material from the first section 182 to be received, travel and exit the second section 186. Further, the second section bore 188 can convergingly taper in a direction away from the first section 182 at a second section angle θ5 so that a first width or diameter of the second section bore 188 adjacent the first section 182 is greater than a second width or diameter of a free end of the second section 186 opposite the first section 182. The second section angle θ5 can be the same or different to that of the first section angle θ4.

A width or diameter of the second section 186 including the external threads 189 and/or a width or diameter of the first section 182 can be configured to be inserted through the dispensing end opening 22, as best illustrated in FIG. 25. In some embodiments, the dispensing end opening 22 is configured to prevent the housing of the piercing nozzle 170 from passing therethrough. When the piercing nozzle 170 is assembled in the dispensing end section 20, the ledge 176 and/or the nozzle end wall 178 can abut or contact an end wall of the dispensing end section 20 that includes the dispensing end opening 22.

In some embodiments, mixing elements (not shown) can be incorporated into or with the first section bore 184 and/or the second section bore 188 to provide a mixing of different materials dispensed from the sausage package 2.

In some embodiments, the piercing nozzle 170 can include the internal rib 60, 110 or an internal rib similar thereto that extends laterally across the first section bore 184, or laterally across the second section bore 188.

One or more piercing projections 190, as best illustrated in FIGS. 19 and 20-25, can extend from an underside or interior surface of the nozzle end wall 178 that defines the nozzle cavity 174, and into the nozzle cavity 174. In the exemplary, each of the piercing projections 190 can include a piercing wall 192 extending into the nozzle cavity 174, and a support member 202 connecting the piercing wall 192 and the nozzle end wall 178. In some embodiments, the each of the piercing projections 190 can be associated with or connected to a threaded ring (not shown), with the threaded ring being configured to threadably engage with threading extending into the nozzle cavity 174 or the first section bore 184. This threaded ring and piercing projection arrangement can allow for the use of different configurations of piercing projections including, but not limited to, varying number of piercing projections, piercing projections with various configurations or characteristics, or with no piercing projections.

The piercing wall 192 can include an interior surface 194, an exterior surface 196, and angled edges 198 that converge toward each other to form a piercing tip 200 to form a generally V-shape at a free end of the piercing wall 192. In some embodiments, the angled edges 198 can be planar or curved. Further in some embodiments, the angled edges 198 can each be a sharp, serrated or pointed edge from a free edge of the piercing wall to the piercing tip 200, thereby creating a cutting edge leading up to the piercing tip 200 from both sides, respectively.

The piercing projections 190 can be radially arranged around an open end of the first section bore 184, thereby defining an open space between the radially arranged interior surfaces 194 of the piercing projections 190. Each of the piercing walls 192 can have a longitudinal length that has the piercing tip 200 terminate within the nozzle cavity 174, at a location equal to the free end or edge of the nozzle sidewall 172, or at a distance exterior or extending out from the nozzle cavity 174.

In some embodiments, the open space between the radially arranged interior surfaces 194 of the piercing projections 190 can include the internal rib 60, 110 or an internal rib similar thereto that extends laterally across the open space between the interior surfaces 194 oppositely located piercing walls 192.

The piercing wall interior surface 194 of the one or more of the piercing projections 190 can be aligned with the interior surface of the first section 182 that defines the first section bore 184 so that a piercing angle of the piercing wall interior surface 194 diverges in a direction away from the nozzle end wall 178 at the angle θ4. This arrangement can create a smooth and flush interior surface including an interior surface of the first section 182 and the piercing wall interior surface 194. In some embodiments, the piercing wall interior surface 194 can be parallel with the longitudinal axis of the nozzle 170 or can extend away from the nozzle end wall 178 at an angle different to that of the angle θ4.

As best illustrated in FIGS. 19 and 23-25, a lateral profile of the piercing walls 192 can be curved or arcuate at a radius similar to or equal to a radius of the first section 182 or the interior surface of the first section 182 that defines the first section bore 184. The curved nature of the piercing walls 192 further provides a smooth and flush transition from the interior surface 194 and the interior surface of the first section 182 that defines the first section bore 184.

The angled edges 198 and/or the piercing tip 200 can be configured to easily pierce or puncture a casing of the sausage package 2 when pressed thereagainst. Further, the angled configuration of the interior surface 194 of the piercing walls 192 can guide the material flowing from the pierced sausage package 2 in a converging manner towards the second section bore 188 and accordingly dispensed therefrom. This smooth and flush continuous surface can create a clear path for material to pass or travel therethrough.

The support member 202 of each of the piercing projections 190 can extend at an angle between the interior surface of the nozzle end wall 178 and the exterior surface 196 of the piercing wall 192. The support member 202 can meet the piercing wall 192 either at a location adjacent to or offset from to make a separation from the piercing tip 200, or directly at the piercing tip 200. This separation can be configured to assist in separating a pierced portion of the casing of the sausage package 2 away from the remaining portion of the sausage package 2. Such a separation can allow for the creation of a larger pierced opening in the sausage package 2, thereby providing easier flow of material out from the sausage package 2 when the dispensing device 12 is operated.

The retaining wall 210 can be a substantially circular or oval wall extending from the interior surface of the end wall 178 and into the nozzle cavity 174. A width or diameter of the retaining wall 210, and thus its orientation, can be greater than a radial dimension, width or diameter of all the piercing projections 190 in a radial arrangement. Accordingly, the piercing projections 190 can be located within an interior space defined by the retaining wall 210. In some embodiments, the retaining wall 210 can take for form of any geometrical configuration and/or can include multiple segments surrounding the piercing projections 190.

The retaining wall 210 can extend from the nozzle end wall 178 at a height, length or distance that is less than the longitudinal length of the piercing walls 192 or where the support member 202 meets the piercing walls 192. In some embodiments, the height of the retaining wall 210 can vary along its radial length, thereby creating an undulating or serrated configuration with peaks and troughs.

An exemplary function of the retaining wall 210 can be to assist in accomplishing 100% evacuation of the material contained in the sausage package 2. The retaining wall 210 can be configured to create a “pinch” point that allows for not only 100% evacuation of the material but also to provide a clean puck, piston or plunger for disposal at an end of the products use.

Referring to FIG. 25, it can now be understood that the piercing nozzle 170 of the present technology can be used with a dispensing device 12 to dispense a material, such as but not limited, caulk, adhesive, sealant, paste, cement, and the like, from a sausage package 2. In exemplary use, a user can insert the sausage package 2 inside the package tube 28. The plunger 140 can be attached to the plunger rod 16 or the adapter 24, if not already part thereof. With the plunger rod 16 retracted, access to the internal cavity of the dispensing device 12 is allowed, and the piercing nozzle 170 can be inserted into the dispensing end section 20 so that the male member 180 is received through dispensing end opening 22 of the dispensing end section 20. The nozzle tip 160 can then be fitted with the second section 186.

While the plunger rod 16 is retracted, the sausage package 2 or the package tube 28 with the sausage package 2 therein can be inserted into the internal cavity of the dispensing device 12 so that a first end of the sausage package 2 is received in the nozzle cavity 174 of the piercing nozzle 170 or one of the open ends of the package tube 28 is adjacent the nozzle cavity 174.

In some embodiments, the sausage package 2 can be inserted into the interior space of the main housing 14 so that the first end of the sausage package 2 is receivable in the nozzle cavity 174 of the piercing nozzle 170.

With the piercing nozzle 170 and sausage package 2 or the package tube 28 with the sausage package 2 therein being installed in the interior space of the main housing 14, the user can then operate the dispensing device 12 to advance the plunger rod 16 which advances the plunger 140 toward a second end of the sausage package 2.

Continued operation of the dispensing device 12 further advances the plunger 140 and pushes the sausage package 2 through the hollow interior of the package tube 28 so that the first end of the sausage package 2 is received in the nozzle cavity 174 and pressed against the piercing projections 190. This advancement of the sausage package 2 by the plunger 140 allows for the piercing tip 200 to puncture through the first end of the sausage package 2, thereby opening a passage between the interior of the sausage package 2, the nozzle cavity 174, the first section bore 184, and the second section bore 188.

In some embodiments, rotation of the nozzle 170 during or after piercing of sausage package 2 can cut a circular section from the end wall of the sausage package 2. This cutting of a circular section can be achieved by a slicing nature of the piercing tip 200 and/or the sharp angled edges 198 during rotation of the nozzle 170.

Continued advancement of the plunger 140 can force the material out of the sausage package 2, over through the piercing projections 190 and the interior surfaces 194, and then through the first section bore 184 and the second section bore 188. The material can then be forced through the hollow interior of the nozzle tip 160 and dispensed out an opening defined or cut in a dispensing end of the nozzle tip 160.

In the exemplary, the user can visually determine the amount of material remaining in the sausage package 2 through the transparent package tube 28.

The sausage package 2 can be removed and replaced by operating the dispensing device 12 or the plunger rod 16 to withdraw the plunger 140 away from the piercing nozzle 170. The user can then remove the sausage package 2 or the package tube 28 with the sausage package 2 therein from the internal cavity of the main housing 14. The emptied or used sausage package 2 can then easily be removed from the package tube 28 and discarded.

After which, the nozzle tip 160 can be removed from the second section 186 so that the piercing nozzle 170 can be removed from the dispensing end section 20 for cleaning or replacement. Further, the plunger 140 can be removed from the plunger rod 16 or adapter 24 for cleaning or replacement.
