The present invention pertains to RV/Marine toilets. More particularly, the invention relates to a method and apparatus to condition an RV/Marine toilet bowl seal and to control odor emanating from the RV/Marine toilet.
In one respect, disclosed is an apparatus for conditioning an RV/Marine toilet bowl seal comprising: a plug comprising: a handle portion; and a solid foam coupled to the handle portion; wherein the handle portion is configured to allow a user to insert or remove the solid foam of the plug from a discharge opening of an RV/Marine toilet bowl; and wherein the solid foam is configured to make contact with at least a portion of the RV/Marine toilet bowl seal.
In another respect, disclosed is a method for conditioning an RV/Marine toilet bowl seal, the method comprising: providing an apparatus comprising: a plug comprising: a handle portion; and a solid foam coupled to the handle portion; wherein the handle portion is configured to allow a user to insert or remove the solid foam of the plug from a discharge opening of an RV/Marine toilet bowl; and wherein the solid foam is configured to make contact with at least a portion of the RV/Marine toilet bowl seal; pouring a conditioner into the discharge opening of the RV/Marine toilet bowl; and inserting the plug into the discharge opening of the RV/Marine toilet bowl such that the solid foam contacts with at least a portion of the RV/Marine toilet bowl seal.
In yet another respect, disclosed is a method for conditioning an RV/Marine toilet bowl seal, the method comprising: providing an apparatus comprising: a plug comprising: a handle portion; and a solid foam coupled to the handle portion; wherein the handle portion is configured to allow a user to insert or remove the solid foam of the plug from a discharge opening of an RV/Marine toilet bowl; and wherein the solid foam is configured to make contact with at least a portion of the RV/Marine toilet bowl seal; loading the solid foam with a conditioner; and inserting the plug into the discharge opening of the RV/Marine toilet bowl such that the solid foam contacts with at least a portion of the RV/Marine toilet bowl seal.
Numerous additional embodiments are also possible.
Other objects and advantages of the invention may become apparent upon reading the detailed description and upon reference to the accompanying drawings.
While the invention is subject to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings and the accompanying detailed description. It should be understood, however, that the drawings and detailed description are not intended to limit the invention to the particular embodiments. This disclosure is instead intended to cover all modifications, equivalents, and alternatives falling within the scope of the present invention as defined by the appended claims.
One or more embodiments of the invention are described below. It should be noted that these and any other embodiments are exemplary and are intended to be illustrative of the invention rather than limiting. While the invention is widely applicable to different types of systems, it is impossible to include all of the possible embodiments and contexts of the invention in this disclosure. Upon reading this disclosure, many alternative embodiments of the present invention will be apparent to persons of ordinary skill in the art.
Many RV/Marine toilets comprise a base portion, a bowl portion mounted to the base and having a discharge opening at the lower end of the bowl, a bowl valve at the discharge opening, and a sealing member configured to seal the bowl to the base and to wipe the bowl valve during the flushing of the toilet. The sealing member is also effective in trapping the odors from the base portion of the toilet from escaping into the bowl portion and ultimately into the RV or boat. Unfortunately, the effectiveness of the sealing member degrades over time, due to the drying and cracking of the seal from aging, as well as to improper maintenance due to the use of petroleum based lubricants which break down the seal.
A need exists for a method and apparatus for maintenance and conditioning of the seal as well as for odor control. The embodiment or embodiments described herein solve these problems and others by proposing a new method and apparatus to condition an RV/Marine toilet bowl seal and to control odor emanating from the RV/Marine toilet.
In some embodiments, the apparatus 100 for RV/Marine toilet bowl seal conditioning and odor control comprises a plug 105 and a storage housing 110 for the plug. The plug 105 comprises a handle portion 205 configured to allow a user to easily insert or remove the plug from the discharge opening 405 of the RV/Marine toilet bowl 410 and a solid foam 210 coupled to the handle portion. In some embodiments, the solid foam 210 comprises an open-cell structured foam which is capable of absorbing a conditioner 610 which conditions the RV/Marine toilet bowl seal 415 and prevents unwanted odors from coming up into the RV or boat when the solid foam portion of the plug 105 is inserted into the discharge opening of the RV/Marine toilet bowl 410. The solid foam 210 is configured to be soft and pliable such that it is capable of making contact with the RV/Marine toilet bowl valve 420 and toilet bowl seal 415 as well as sealing against the walls 425 of the discharge opening 405. Other materials besides open-cell structured foam may be used as long as the material is capable of absorbing a conditioner. The conditioner loaded into the solid foam may comprise any lubricant such as Thetford® toilet seal lubricant and conditioner, OUTHOUSE® toilet seal conditioner, or the like.
In some embodiments, the apparatus 100 for RV/Marine toilet bowl seal conditioning and odor control may comprise a securing feature. In one such embodiment, the plug 105 further comprises a ridge 207 on a portion of the plug that is inserted into the storage housing and the storage housing 110 further comprises a recess 305 configured to receive the ridge of the plug. When the plug is inserted into the storage housing, the ridge accommodated into the recess will provide some security from the plug from easily falling out of the storage housing. In some embodiments, the discharge opening of the RV/Marine toilet bowl may comprise a recess similar to that of the storage container in order to secure the plug within the discharge opening. In alternate embodiments, the securing feature may be accomplished through any methods known in the art for securing two individual components together, such as (but not limited to) a screw thread or magnet.
In some embodiments, the RV/Marine toilet bowl may have a ball valve 720 as shown in
Alternatively, in some embodiments, the apparatus 100 for RV/Marine toilet bowl seal conditioning and odor control is formed of a monolithic piece of absorbent material, such as (but not limited to) open-cell structured foam, and the like, all of which are well known in the art for absorption of liquid and gel matter. In such an embodiment, the plug is unibody, with the handle portion and the solid foam made of a single piece of material.
In some embodiments, the solid foam may be removably coupled to the handle portion of the plug. In such an embodiment, the solid foam may be replaced if it deteriorates over time and the handle portion may be reused with a new solid foam.
