Description

FIELD OF THE INVENTION

The present invention is directed toward the manufacture of suppositories generally intended for administering therapeutic, homeopathic, and medical treatments—typically administered rectally or vaginally.

BACKGROUND OF THE INVENTION

The administration of medical or therapeutic compounds rectally or vaginally are used across numerous fields from alternative wellness to traditional medicine. Certain compounds are well accepted by certain communities to provide medical and/or therapeutic benefits when delivered rectally or vaginally. As a result, a growing population of consumers undertake the manufacture and administration of their own suppositories using medicines and compounds which they tailor to their own needs and preferences.

Rectal and vaginal delivery of compounds has been shown to bypass certain shortcomings of traditional medicines. Suppositories are commonly administered when a medication dose is difficult to swallow or is particularly hard on the digestive system. Suppositories can also be administered to bypass the liver to avoid any unwanted side-effects with certain medicines or compounds. For instance, the use of a medicinal Cannabis-based compound containing compounds such as Tetrahydrocannabinol, commonly known as “THC”, within a suppository allows a patient to benefit from the medicinal and therapeutic aspects of the marijuana plant without resulting intoxication of the individual. Other situations when suppositories are preferred over oral medical include: seizure medications if the patient cannot take the medication orally, difficulty in swallowing, nausea and vomiting wherein a patient is unable to hold down oral medication, blockages that prevent medication from moving through the digestive system, oral medication has unpleasant taste, orally administered medication would break down too rapidly in the gut or could be destroyed in the gastrointestinal tract.

Due to the increasing use of suppositories for a variety of conditions and ailments, consumers have increasingly begun to manufacture their own suppositories. The method of manufacturing one's own suppositories typically surrounds the preparation of a mixture in a fluid form having a mixture of compounds to form the suppository. In certain situations, the mixture must be heated in order to achieve a fluid state. The fluid is dispensed into a form which is then placed in a refrigerator or freezer for solidification through cooling. Once solid, a suppository can be removed from the mold and administered as desired.

After administration, the suppository dissolves melts and/or dissolves releasing the medication into the surrounding tissue and directly into the bloodstream.

SUMMARY OF THE INVENTION

The present invention surrounds a method and apparatus for the manufacture of suppositories intended to increase ease of manufacture and cleanliness. Embodiments of the present invention as disclosed provide an apparatus for the manufacture of suppositories.

Certain existing apparatus and methods of manufacturing suppositories include the use of open molds offering a cavity which is top-filled through an orifice, wherein the orifice remains exposed to the ambient environment. This open orifice may cause for concern to some surrounding the cleanliness and quality control of the resultant suppository.

In is an aspect of the present invention to allow the manufacture of suppositories with minimal interface with the user, surfaces such as countertops and minimal exposure to air.

Certain existing apparatus and methods of manufacturing suppositories include the top-filling of multiple small cavities through each open-topped cavity. As a result, this compounds time for manufacture and increases the possibility of spilling the fluid for manufacturing suppositories during the manufacture process. Furthermore, since each cavity is individually filled, this results in a lack of consistency of suppository size within the same batch of suppositories.

It is an aspect of certain embodiments to include an aperture through which fluid is poured to fill multiple chambers. The aperture allows a user to fill multiple chambers with fluid evenly, thus resulting in a consistent amount of fluid delivered to each chamber, and resulting in a consistent suppository size. The filling of multiple chambers through one aperture improves time efficiency of the manufacture of suppositories and prevents spillage, thereby mitigating the wasting of prepared fluid. The filling of a multiple cavities through one aperture results in the even filling of each chamber, resulting in consistently sized suppositories within the same batch.

In certain embodiments, an apparatus includes a funnel for the direction of suppository material into an aperture to mitigate spillage of the suppository material.

In certain existing mold technologies, a user has no way to identify the level to which a mold should be filled or to what level the cavities are filled to. Sometimes sighting from above the mold is required, in other instances a user must rely on the practice of stopping the fill process once the mold overfills. This can result in a messy and wasteful filling process.

It is an aspect of certain embodiments to address the filling of a mold to limit messiness and waste. Certain embodiments comprising an apparatus include a fill-line which indicates to a user that the molds have been filled to a proper level. It will be appreciated that a fill-line as appreciate by those skilled in the art includes a protuberance or depression indicating the proper fill level. Other examples of a fill-line include, but are not limited to, translucent or transparent material allowing a user to see the level of fluid within a cavity through a surface. A fill-line indicates to a user when the mold is properly filled, thus mitigating pouring excess fluid into the mold.

It is an aspect of certain embodiments to indicate to a user when fluid used for manufacturing suppositories has become solid. In certain embodiments, the indication of temperature within the chambers of a mold indicate to a user the status of the fluid within the chamber. In certain embodiments, a color-changing indicator communicates to a user when the fluid has reached a particular temperature indicating proper solidification.

It is an aspect of certain embodiments to include a first mold side having a plurality of cavities and a second mold side having a plurality of cavities for the manufacture of suppositories. The first mold side and second mold side are configured in a clam-shell form such that when the clam-shell is in a closed configuration, the cavities of the first mold side align with the cavities of the second mold side to create a plurality of chambers. Furthermore, when the clam-shell is in a closed configuration, fluid disposed through the aperture to fill the plurality of chambers is prevented from leaking between the internal surface of the first mold side and the internal surface of the second mold side. In certain embodiments a plurality of cavities can be filled through one aperture. After the suppositories have solidified, the clam-shell can be opened to disengage the first mold side from the second mold side enabling the removal of suppositories.

An advantage to the filling of a plurality of cavities through one aperture includes consistency in composition of a plurality of suppositories from the same batch. A prepared mixture of suppository material in fluid form may be subject to settling or separation, resulting in a non-homogenous mixture. Delivery of a non-homogenous mixture to a plurality of cavities individually in sequence would result in a plurality of suppositories being inconsistent and result in a plurality of suppositories having dissimilar compositions. Inconsistency in the production of suppositories can be dangerous particularly with those using medicine. Inconsistency in the production of suppositories can result in some suppositories of a batch having more medicine than intended, and other suppositories within the batch not receiving enough medicine. The use of one aperture to fill a plurality of cavities results in each cavity receiving similar material composition even if the prepared mixture of suppository material is non-homogenous.

In certain embodiments, a funnel connected to an aperture in the top surface of a second mold side further mitigates spillage when delivering fluid through an aperture. A funnel allows a user to dispose fluid into an apparatus requiring less accuracy and allowing for higher flow rates.

It is an aspect of certain embodiments surrounding an apparatus to comprise a primer bulb. It will be appreciated that a primer bulb surrounds a volume, typically of a substantially hemispherical form, constructed of a flexible material. Depression of a primer bulb causes can be used to create positive pressure downstream from the primer bulb. In certain embodiments, releasing the primer bulb allows the primer bulb to rebound to its original form and cause negative pressure upstream of the primer. The use of a primer bulb in certain embodiments is used to assist in the complete filling of molds within the apparatus when filling.

In certain embodiments, the present invention is configured for use in conjunction with existing technologies such as disclosed in U.S. Pat. No. 9,795,246 to Bellman et al. (“the '246 patent”) for purposes such as to increase efficiency and repeatability in the manufacture of suppositories.

Surrounding the home manufacture of suppositories, there is concern expressed by some about the sanitary aspect of home manufacturing of suppositories in an unregulated surrounding such as a home kitchen. It is an aspect of the present invention to mitigate sanitary concerns by minimizing user contact with fluid suppository material or solid suppositories. In certain embodiments, an apparatus comprises an ejection mechanism which allows a user to remove molded suppositories from the apparatus without direct contact with the suppository. In certain embodiments, an ejection mechanism comprises a push-button having a first side exposed to the exterior of the apparatus, and a second surface in communication with a cavity. Thus, a user is able to eject the molded suppository without requiring direct contact with the suppository.

It is a further aspect of certain embodiments that an apparatus serves as a convenient storage container for suppositories until use, thus preventing damage from freezer burn and preventing jostling which may deform or damage the suppositories.

These and other advantages will be apparent from the disclosure of the inventions contained herein. The above-described embodiments, objectives, and configurations are neither complete nor exhaustive. As will be appreciated, other embodiments of the invention are possible using, alone or in combination, one or more of the features set forth above or described in detail below. Further, this Summary is neither intended nor should it be construed as being representative of the full extent and scope of the present invention.

In certain embodiments comprising an apparatus 1000, as shown in FIG. 2A-FIG. 2B, a first side of a mold 1010 comprises a push-button 2000 for the removal of a suppository from the first mold side 1010. In certain embodiments, a push-button 2000 comprises a membrane 2010 between an internal cavity surface 2020 an external surface 2030 of the first mold side. The membrane 2010 comprises an elastic material allowing for deflection of the membrane 2010 into the cavity 1030. In certain embodiments a push-button 2000 comprises a membrane 2010 comprising a perimetral aspect 2040 and a central aspect 2050, wherein a thickness 2051 of the central aspect 2050 is comparatively thicker than a thickness 2041 of the perimetral aspect 2040. In certain embodiments, the central aspect 2050 comprises a width 2052 less that a width 1032 of the cavity of the first mold side. In such embodiments the thicker central aspect 2050 prevents the unintentional distortion of the shape of the suppository, while the thinner perimetral aspect 2040 deflects, thus resulting in the ejection of the suppository from the cavity 1030 of the first mold side. In certain embodiments, the push-button 2000 conforms with the bottom 2020 of the cavity of the first mold. Thus, the thicker central aspect 2050 of the push-button maintains the shape of the suppository and mitigates deformation of the suppository while being ejected. In certain embodiments, elements of the push-button 2000, such as the membrane 2010 of the push-button, comprises an elastic material such as silicone, rubber, or other elastomers known to those skilled in the art. In certain embodiments, a central axis 2005 of the push-button is colinear with a central axis 1035 of the cavity of the first mold side. It will be appreciated that as a cavity 1030 of the first mold side can comprise a number of profile shapes, such as circular, ovular, oblong or other shapes appreciated by those skilled in the art, the push button 2050 of certain embodiments comprises a similar profile to that of the cavity.

In certain embodiments, shown in FIG. 2A-FIG. 3B, a second mold side 1020 comprises a channel 3000 which directs fluid, such as suppository material, toward a cavity 1030 in the second mold side 1020. In certain embodiments, a plurality of channels 3000 direct fluid to a plurality of cavities 1030 in the second mold side. A first end 3001 of the channel is interconnected with the aperture 3010, and a second end 3002 of the channel is interconnected with the cavity 1030 of the second mold side. such embodiments, the second mold side 1020 comprises an aperture 3010 in an external surface 3020 of the second mold side. The aperture 3010 is in direct communication with at least one channel 3000. The channel 3000 traverses from the aperture 3010 to an internal surface 3025 of the second mold side. In certain embodiments the channel 3000 is in direct communication with a cavity 1030 of the second mold side. The channel 3000 is configured to carry fluid from the aperture 3010 to a cavity 1030 or to a plurality of channels 1030 configured to fill a plurality of cavities 1030. In certain embodiments, a plurality of channels 3000 in direct communication with the aperture are also in direct communication with a plurality of cavities 1030 in the second mold side, thus the channels 3000 are configured to carry fluid from the aperture 3010 to the plurality of cavities 1030 in the second mold side. As such, pouring fluid into the aperture 3010 from the external surface 3020 of the second mold side, results in the fluid passing through the aperture 3010 and into the channel 3000 to fill one or more chambers 3030. It will be appreciated that the channels 3000 of certain embodiments as discussed herein are configured to direct fluid flow to a plurality of cavities 1030 at the same time, thus resulting in the simultaneous filling of a plurality of chambers 3030.

In certain embodiments, referencing FIG. 3A-FIG. 3B, channels 3000 are encapsulated within the second mold side 1020 of an apparatus 1000. In alternate embodiments, channels 3000 can be encapsulated within the second mold side 1020 of the apparatus, in an internal surface 3040 of the first mold side, in an external surface 3020 of the second mold side, or a combination thereof while in keeping with the spirit and scope of the present invention. In certain embodiments, channels are configured to communicate with a cavity of the first mold side 1010. Furthermore, in certain embodiments, channels 2000 are configured to communicate fluid with a cavity of the first mold side 1010 thus allowing a chamber 3030 to be filled in a bottom-up filling process.

In certain embodiments, shown in FIG. 4, the method of manufacturing suppositories comprises closing 4000 an apparatus by engaging a first mold side with a second mold side thereby aligning the cavities of the first mold side with the cavities of the second mold side to form chambers. Following the closing 4000 of the mold, the filling 4010 step surrounds the pouring of fluid, such as prepared fluid for the manufacture of suppositories, into the chambers. In certain embodiments, the filling 4010 step comprises the pouring of fluid into an aperture having direct communication with a plurality of chambers. Following the filling 4010 step, the cooling 4020 step involves the decrease of temperature of the fluid until solid. Following the cooling 4020 step, the opening 4030 step involves disengaging the first mold side form the second mold side. Following the opening 4030 step, the pushing 4035 step involves the use of an ejection mechanism, such as a push-button, to advance the suppository upward from the first mold side which increases the ease of removal. For instance, with the use of a push-button having a membrane, a user disposes a finger on an exterior surface of the push-button and applies a force toward the cavity of the first mold side, resulting in the deflection of the push-button toward the cavity of the first mold side and thus ejecting the suppository from the cavity of the first mold side. Following the pushing 4035 step, the removing 4040 step surrounds the user pulling the formed suppository from the first mold side.
