The present invention relates to a removable pet waste cartridge used in combination with a pet waste machine system and, in particular, to a generally removable and disposable pet waste cartridge that disposes of both the waste and its odor that are contained within a generally sealed waste pad when the pad is rolled up in its finished state for removal from the waste machine.
There are millions of pet dogs in the United States and the rest of North America. Many dog owners even have more than one dog within their residence in Urban and Rural North America. This large number of dogs excretes a large amount of both liquid and solid waste each day of the year. Due to the busy commitments and work schedules of pet owners, the dogs are left in the residence unattended for hours or days at a time to accommodate work and event schedules of the pet owners. Dogs are known to urinate several times a day and excrete solid wastes at least once daily too. Dog owners want to keep their residences clean and without the attendant odor accompanying either urination or solid waste excrement. Pet owners are also known to teach their dogs or pets to eliminate their bodily wastes on paper within their residences or condition their pets to eliminate their waste outdoors when the pet owner takes the pet for a walk outdoors. Many municipalities have adopted “pooper scooper” laws for sanitary reasons that means pet owners are picking up nasty solid waste on their walks with the pet outdoors.
Outdoor elimination of pet waste can become problematic due to extreme weather conditions found by pet owners in the time allotted to daily walk their pet. If the weather is nasty, the walk often gets postponed or delayed that stresses out the pet. Therefore, housebreaking pads are used by tens of thousands of home owners with their puppies and dogs around the country. Dog owners, especially in large cities where dog parks and available yards are at a minimum, generally prefer to “paper” train their pets. Because of work schedules, some owners may not get home to walk the dog on time, so they “paper” train the pet to use the pads to prevent the dog from eliminating indiscriminately in the house or apartment. Many apartment dwelling dogs, especially among the smaller breeds, are “paper” trained exclusively. Whether they are used for housebreaking for puppies or for “paper” training indoor dogs, who will use these pads throughout their lifetime, housebreaking pads are one of the larger expenditures for dog owners.
In U.S. Pat. No. 8,464,662, describes An Apparatus that maintains housebreaking pads for a pet owner, automatically removing and sealing soiled pads and waste and replacing the soiled pad with a clean pad. The apparatus senses when a pet is using a housebreaking pad, and when the pet is finished, removes and seals the pad and the waste automatically, moving the pad into a repository for later disposal and replacing the soiled pad with a clean pad. The apparatus seals the waste and pad with plastic film having low vapor permeability for disposal on a once-daily or less frequent basis. The apparatus minimizes or eliminates odors associated with canine elimination by removing the pads immediately after elimination is completed, and sealing the waste. A control unit, triggered by a sensor, has a single cycle or a multiple cycle operation, operating a motor that rolls the soiled composite pad onto an arbor in the repository.
Another major problem that plagues pet owners is the annoyance of replacing soiled pads. Offensive odors from the soiled pads may permeate the household. Owners need to flush the feces down a toilet or place in a sealed container to decrease the odor. Dogs, especially puppies, when stressed sometimes develop the undesirable habit of eating their own feces. If the dog develops the habit, the dog owner needs to pick up fecal matter quickly to break the habit. Disposing of the fecal matter and the pads is not only a continual annoyance, but also causes dog owners to bend down multiple times a day, often bothering the lower back and stressing the knees. There is also the possibility that the pet owner will end up with urination or fecal matter on their hands, clothing or other residential items when disposing of open faced pads or paper haphazardly rolled up to contain the pet waste. This is especially burdensome to the elderly, physically handicapped, and blind who have companion, assistance, or guide dogs. The handling of pet waste may also affect the overall health of the elderly person who comes in contact with fecal or urination on their hands and clothing and due to poor eyesight or numbness in their fingers does not realize that the pet waste is still on their hands.
An object of the present invention is to provide a removable and disposable pet waste cartridge.
A further object of the present invention is providing a removable pet waste cartridge where a pet owner avoids touching the pet waste at time of disposing of a spent pet waste cartridge.
Another object of the present invention is to provide a pet waste cartridge that seals in the liquid and solid pet wastes when the waste pad is rolled up into a final state for disposal.
A removable waste cartridge in combination with a pet waste machine comprises a pad in a roll of a predetermined diameter, length and width having an absorbent front side and a back side of non-permeable material. A take-up rod passes through the axis of the pad during its take-up on the rod. A pair of end caps is mounted at opposing ends of the rod for guiding the take-up function of the soiled portion of the pad. The pad roll of the waste cartridge is placed in a supply assembly at one end of the waste machine to have one end of the roll stretched across a pet bed on the machine for a connection to a take-up rod with a pair of end caps mounted on opposing ends of the rod that is located in the take-up assembly during operation of the machine.
Further, the waste machine advances the roll of pads either manually or automatically after pet waste is deposited and then observed, or automatically detected on the pad until the entire roll of pads is wound around the take-up rod and ready for disposal with the end caps holding the pet waste and attendant odor therein.
Moreover, a pet waste removable cartridge for use with a pet waste machine comprises a take-up core of a predetermined diameter, length and width. The roll of waste pad formed by winding a flexible material around the core, said roll of waste pad having an absorbent waste surface on one side and a non-permeable surface on the other side; and a pair of generally cylindrical end caps although the end caps are capable of other shapes as a square or other shapes between a circle and a square mounted on opposing ends of the core for guiding the rolling of the pad around the core during the take up of the waste pad when winding it around the core. The pet waste removable cartridge includes a take up core or rod passing through the axis of the rolled up waste pad in the take-up assembly.
The pet waste removable cartridge has one end of the waste pad attached to the rod by tape by holes in the pad fitting over corresponding pins mounted on the rod, by feeding the pad through a slot in the rod including a tapering of the pad to facilitate the feeding of the pad through the slot, and by feeding the pad under one or more clips integrally formed on the rod or integrally formed on the end cap. The pet waste removable cartridge includes the end caps to seal or partially seal exposed ends of the rolled up waste pad to contain the odor and waste therein.
The pet waste removable cartridge with at least one end cap provides an interface with the waste machine for manual or automatic advancement of the waste pad therethrough. The waste pad is capable of manually being advanced from the supply assembly to the take-up assembly by a handle crank mechanically connected to the rod or by a toot treadle that is mechanically connected to the rod when stepped upon or a foot roller mechanically connected to the rod for its rotation. The pet waste removable cartridge requires the take-up core to interface directly to a mechanism for manual or automatic advancement of the waste pad with or without the end caps.
The pet waste removable cartridge includes a waste pad with a series of marks for detection by waste machine to determine pad status in the machine. For example, the end user requires information about how much waste paper or pad is left in the supply assembly. Also, when a new roll is installed to replace a spent one, the machine needs to know that a new roll of waste paper is installed. And there are many more signals to the machine by how the series of mark or holes or notches on the paper are capable of indicating or configuring the machine with its electronic control components and drive motor within the control module.
A roll of pet waste paper for use with a waste machine comprises a waste pad or paper with an absorbent front side material and a non-absorbent back side. This configuration of the roll of waste paper prevents leakage of urine and feces from the pet through the waste paper. The marks on the roll of waste paper further alerts the end user of various states of the roll of waste paper as it is consumed by manual and automatic advancement through the machine per a designed program entered into the control module by the end user. The mark on the waste paper provides information for determining future use or information on how to set up the machine for future use by the end user. The marks on the pet waste paper are printed on either the front or back sides of the waste paper. In addition, the marks on the pet waste paper are either visible or invisible on the front or back sides of the waste paper. The marks on the pet waste paper are absorptive or reflective to infrared light, I_TV light or other light spectrums. The marks on the pet waste paper are often printed at predetermined spaced intervals or at variably spaced intervals usually at one of the edges along a length of the paper. The marks on the pet waste further include holes or notches on the paper that replace or add to the marks on the waste paper. The pet waste paper as recited in claim 15 wherein the paper includes an absorptive non-woven spun bond on a top layer for tear resistance, an absorbent polymer in a middle layer and a plastic non-absorbent bottom layer for leak protection from the liquid and solid waste.
An apparatus for receiving, removing and sealing a pet waste within a roll of pads comprises a pet waste station having a generally flat parallel surface with respect to a floor and at a predetermined heights above the floor for a pet to easily step from the floor onto the waste station in order to urinate or leave solid waste behind on a portion of the exposed roll of pads laying across the flat surface of the waste station that becomes soiled by the pet waste; a supply housing for holding a fresh supply of roll of pads therein connected to one end of the waste station; and
The system includes An apparatus having predetermined cycles for automatically removing a pet soiled pad and replacing the removed soiled pet pad with a fresh pet pad to minimize the odor from the soiled pad comprising a pet waste platform configured to be a predetermined height above the floor and to be a predetermined width and length; a supply housing for receiving a fresh roll of pads located at one end of the length of the platform having a generally cylindrical or geometric trough shape with a bottom half generally below the waste platform and a cover top half for securing the fresh supply of pads within the supply housing;
A pet pad for capturing liquids or solid wastes comprises a roll of a laminate pad material capable of receiving and absorbing liquids or solid wastes having a predetermined diameter, length, width and thickness configured to be stretched across a pet waste bed from a supply end to a take up end of an automatic or a manual pet waste machine; and at least one marking on a flat surface of the laminate pad material for determining usage of the pad material by the machine.
A pet laminate for collecting urine and solid wastes comprising
Embodiments of the present disclosure are described by way of following drawings pointing out the various details to the inventive automatic or manual pad roll system. The main features and advantages of the present disclosure will be better understood with the following descriptions, claims, and drawings, where:
The repository portion is aesthetically covered by a cylindrical half portion of the machine 14 attached to the pet bed 16 with a rotatable cover 34 in the take-up assembly 20 to hide the soiled portion 12 of the pad roll 26. The elimination stage portion for the pet 22 has the machine bed 16 connected between the supply and take-up assemblies 18 and 20, respectively, where the waste pad portion 12 therebetween is set on top of the pet bed 16. The pet 22 stands on top of the pad portion 12 on the pet bed 16 and eliminate feces 24 and urine. The supply assembly also has a rotatable cover 32 with a lower cylindrical portion 29 for receiving the pad roll 26 of a predetermined length, width and diameter. The pad roll 26 when housed within the supply assembly 18 has its axis below the pet bed 16 and the waste pad portion stretched across the bed 16 to the take-up rod 28 is below the pet bed 16 to create the proper friction and tension of the pad 12 across the bed without jamming or hampering the take-up of the soiled portions of the pad roll 28 within the take-up assembly 20. The covers 32 and 34 on the supply and take-up assemblies, respectively, when closed further the proper tension of the waste paper or pad portion 12 moving across the bed 16 from the supply to the take-up assemblies, respectively, as shown in
As further shown in
In
Then the covers of the supply and take-up 32 and 34, respectively, are closed and the waste machine is ready to accept its first dog or other pet for the elimination of its waste.
A roll of pet waste paper 26 for use with a pet waste machine 14 comprises an absorbent front side material on a roll of pet waste paper and a nonabsorbent back side material on the roll of waste paper or waste pad. Further, the waste paper or pad includes an absorptive non-woven spun bond on a top layer for tear resistance, an absorbent polymer in a middle layer and a plastic non-absorbent bottom layer for leak protection from the liquid and solid waste. The pet waste paper may also include an air laid paper top layer allowing the removal of other layers. The pet waste paper is capable of being configure to include either a four or five layer construction with the mixing of absorbent and non-absorbent or non-permeable layers.
The paper or pad is generally composed of five layers but may be as little as just one layer too. The top sheet 270 is a bonded layer to prevent dog paws from ripping the paper. The next layer is a tissue layer 272 that helps to absorbed the liquids from the dogs urination. The layer 274 is the super absorbent polymer layer that helps absorb both the liquid urination and anything off of the solid deposit from the dog's defecation. Next comes another tissue layer 275 for further liquid absorption and finally the bottom layer 278 made of a plastic or similar non-absorbent or impervious to liquids to prevent any other urine or solids to leak through the rolled up soiled roll of pads ready for removal and deposit before a fresh supply of roll of pads is installed in the supply and connected to the rod assembly in the take up housing.
This present invention is a non-provisional application of U.S. Application Ser. No. 62/345,500 filed Jun. 3, 2016 entitled “Dog Pad”.
