Description

DESICTABLE MATERIAL INCLUDED IN A CLOSED CONTAINER DESCRIPTION TECHNICAL FIELD: The present invention relates to containers having desiccant capacities. More particularly, the present invention relates to thermoplastic containers. PREVIOUS TECHNIQUE: There are many items that are preferably stored and / or shipped in an environment that is as free of moisture as possible. Therefore, it has been recognized that containers that have the ability to absorb excess moisture are convenient. An application in which moisture-absorbing containers are desired is for the shipment and storage of medicines whose effectiveness is compromised by humidity. The initial placement of medicines in a container free of sealed moisture is usually controllable. In addition, the container for the medicine is selected such that it has a low moisture permeability. Therefore, the medication will normally be protected against moisture until it reaches the end user. However, once the consumer receives the medication, the container must be opened and closed repeatedly to access the medication. Each time the container opens and is not sealed, air containing moisture will probably be introduced into the container and sealed after closing. Unless the moisture is somehow removed from the atmosphere or space in the head of the container, it can be detrimentally absorbed by the medication. For this reason, it is a well-known practice to include a desiccant unit together with the medicament in the container. In other cases, moisture can be released from items that have been placed in containers for shipping and / or storage. In the event that the containers are sealed and substantially impervious to moisture, the moisture released will remain inside the container around the product. If not removed, this moisture released can have detrimental effects on each item that released the moisture. It has been found that a substantial amount of moisture is released from certain food products within the first forty-eight (48) hours after manufacture and packaging. This released moisture will remain around the product until it is removed. If the moisture is not removed shortly after its release, it can cause the food to degrade into one that can not be sealed. In these cases, desiccants can be included along with the contained items to continuously absorb the released moisture until the product is unpacked. In this way, a relatively dry environment is maintained around the stored item. Previously it was recognized that the need to remove moisture from inside sealed containers. Early attempts to achieve these goals included the provision of desiccant materials in similar fabrics or bags that are placed in the containers, together and mixed with the materials that will be shipped or stored. However, there is a problem related to the consumer when the desiccant is lost and mixed together with consumable items. If not processed carefully and uniformly upon unpacking, the desiccant can not be separated from the consumables and could harm a person if it is ingested in an unknown way. Another known way in which a desiccant can be provided inside a container includes coating the interior surface of the container container with a material containing desiccant. In addition, it is known that desiccant properties are provided in a container by the use of layered structures in which a desiccant is "sandwiched" between the moisture permeable material that confines the desiccant. These layered structures are often in the form of flexible sheets that can be formed into bag-type containers in which articles that require a low humidity environment are placed. Several of the known means by which the containers carrying desiccant are constructed require multiple steps and result in layered and more complex structures than desired. further, the provision of desiccant capsules together with contained articles is not always satisfactory. As previously explained, the mixture of desiccants with food and drugs is convenient from a consumer's point of view in that the desiccant can be inadvertently ingested. Still further, if the desiccant is not integrally formed with the container, or at least is attached to it, it can be removed prematurely while still needed for continuous removal of moisture from inside the container. Therefore, a need has been recognized for containers that include a desiccant as an integral component of the container body. With respect to the included desiccant of the container, it is convenient to increase its moisture absorption capacities with respect to both the regime and quantity. Moreover, as in all manufacturing processes, it is convenient to reduce the steps required to build the desiccant vessels and simplify the resulting structures. DESCRIPTION OF THE INVENTION: An embodiment of the present invention includes a container having desiccant capabilities. The container includes a container body that forms at least a partial closure so that an interior space and an exterior space is created relative to the container body. There is an insert formed of the thermo-plastic retaining desiccant that is fixed in relation to the body of the container. At least a portion of the insert is exposed to the interior space of the container body so that it can absorb moisture therefrom. The thermoplastic that retains the desiccant from which the insert is constructed, has a high desiccant concentration of at least forty percent desiccant to thermopastic by weight. The body of the container is constituted by thermo-plastic substantially free of desiccant in one embodiment and thermo-plastic with low concentration of desiccant having at most twenty percent desiccant to thermo-elastic by weight in another embodiment. In a preferred embodiment, the body of the container is constructed of polypropylene. A cover that is coupled in seal fashion with the body of the container and constructed of polyethylene can optionally be provided. It is contemplated that the insert can be sufficiently enclosed by the body of the container so that the insert is only exposed to the interior space of the container and not to the exterior of the container. In one embodiment, the insert is fixed to the body of the container by a retaining edge 211 formed by the body of the container around the insert. In another, the insert is fixed to the container body by a shortened adaptation of the container body around the insert. It is contemplated that the insert and container body can be co-molded in a used body. As an optional increase, the thermoplastic that retains desiccant from which the insert is constituted may include a polar organic compound that increases the absorption capabilities of the desiccant. The insert may be in the form of a liner that covers at least a greater part of the interior surface area of the body of the container. An alternative embodiment is described, a container having desiccant capabilities. It includes a container body that forms at least a partial closure so that an internal space and an outer space are created with respect to the container body. There is an insert constructed of thermoplastic that retains desiccant that is integrally joined to the body of the container by a co-molding process that forms a single unified body of two components. After the co-molding process, at least a portion of the insert is exposed to the internal space of the container body to absorb moisture therefrom. A method for co-molding the above container having desiccant capacities is also described. The steps of the method include injecting a thermoplastic insert with high concentration of desiccant into a container mold. A container body is injected around the insert so that a single body used is formed from two components. When the mold of the container is formed, the insert is enclosed within the body of the container so that the insert is only exposed to an interior space of the container. The step of injecting the body of the container around the insert so that a single unified body of the two components is formed. When the body of the container is formed, the insert is enclosed within the body of the container so that the insert is only exposed to an interior space of the container. The step of injecting the body of the container around the insert is carried out contemporaneously with the step of injecting the insert so that the insert and body are fused at an interface whereby the unified body is formed. Alternatively, the injection of the body of the container around the insert is carried out at a sufficiently elevated temperature so that the insert of the body fuses at an interface thus forming the unified body. Before the thermo-plastic is injected into the mold, the different concentrations of the desiccant are prepared. During the injection process, the concentrate thermopylastic with high desiccant content is introduced into the mold through a first injection port 209 and the concentrated thermoeplast without desiccant or with a low desiccant content is introduced into the mold through a second injection port 210. In one embodiment, the mold moves from a first injection station to a second injection station. A preferred means for moving the mold between stations on a rotary table. The present invention provides a container and process for constructing the same that satisfies the need for more effective desiccant storage and shipping containers. These containers of the present invention provide superior desiccant capacities, while at the same time allowing efficient construction of a container that has and maintains structural integrity. In addition, the present invention provides a means by which it can be formed having a substantially unified and continuous body. BRIEF DESCRIPTION OF THE DIAMETERS.

MODES FOR CARRYING OUT THE INVENTION: In one embodiment of the present invention, a relatively small container can be manufactured similar in construction to the aseptic vial and cap of US Pat. 4,783,056 to Robert S. Abrams, the disclosure of which is expressly incorporated herein by reference. In the present application reference numerals similar to those of the 4,783,056 patent are used to designate similar or similar apparatuses or processes. The present invention described includes and applies to the manufacture of similar containers. However, the containers 01 described herein are not limited to the ampoules. It is contemplated that the containers 01 constructed in accordance with the present invention may be larger or smaller than the 4,783,056 ampoules and variable in shape. In addition, the lids 14 can be formed integrally with the bodies 12 of the containers 01, or they can be manufactured as separate units. Furthermore, the present invention can be moralized exclusively within the body of a container 12 or a lid 14 for a container 01. The material used in the construction of these containers 01 normally provides a barrier between the interior 201 and exterior 202 of the container 01 which Substantially it is impervious to moisture and more often is thermopastic. While it is contemplated that any thermoplastic may be used, polypropylene is preferred for the construction of the body 12 of the container 01. Polypropylene is suitable for its durability, rigidity and resistance to breaking after being molded into the shape of a container 01. Other examples of suitable thermoplastics can be selected from the following groups: polyolefin, polyethylene, polycarbonate, polyamide, ethylene vinyl acetate copolymer, ethylene-methacrylate copolymer, polyvinyl chloride, polystyrene, polyester, polyester amide, polyacrylic ester and polyvinylidene chloride , acrylic, polyurethane, polyacetal and polycarbonate. These and other thermoplastics can be used either singly or in combinations. The present invention includes the manufacture of a container 01 in which the majority of the container body 12 is constructed from the base thermoplastic, e.g., polypropylene because of its durability and resistance to rupture. To establish and / or increase a desiccant capacity it is integrally constructed with the body 12 of the container 01. The concentration of desiccant retained within the insert 200 may exceed seventy-five percent (75%). However, normally the desiccant concentration in insert 200 will fall within a scale of forty to seventy five percent (40-75%) of desiccant to thermopastic by weight. This concentration is considered to be a high concentration for most thermoplastics. The maximum amounts of desiccant that can be carried will vary between the different types of thermoplastics due to their different characteristics. However, in the case of polypropylene the maximum desiccant concentration will be about seventy-five percent by weight (75%). As desiccant concentrations within thermoplastics increase, the performance of the material degenerates to unacceptable levels. In one embodiment, the insert 200 is located on the base or bottom 203 of the body of the container 12 and is exposed to the interior space 201 of the container 01. The configuration of this embodiment is similar to a vial of the sample. Because the durability and resistance to rupture is reduced in the upper scales of desiccant content, it is advantageous to have the polypropylene used in the construction of the container body 12 formed around the insert 200 except for those surfaces that will be exposed to the interior 201 of the container 01. A container 01 of this configuration provides desired structural integrity while also providing the capacity larger desiccant of the insert loaded with high desiccant content 200 that is directly exposed to the interior 201 of the container 01. It is also contemplated that the insert 200 may be included in the construction of the lid 14 of the container. In this case, the insert will be formed integrally with the lid 14 so that the outer surface of the insert 200 is exposed to the interior 201 of the container 01 when installed thereon. As a further alternative embodiment, the insert 200 may be less localized and extended to a high degree around a larger portion of the inner surface 204 of the container body 12. In this case, the bearing thermoplastic with high desiccant content forms more of a liner 205 on the inner surface 204 of the container 01. To provide maximum desiccant capacities the liner 205 can completely cover the interior surface 204 of the container 01; this may optionally include the surfaces exposed internally of the lid 14 of a closed container 01. A contemplated method of manufacturing the container 01 includes the provision of a preformed insert 200 around which the thermo-elastic of the remainder of the body 12 of the container 01 is injection molding. In this process, it is important that the insert 200 be fixed to or within the body 12 of the container 01. This can be achieved merely by molding the body 12 around the insert 200 so that the two components are mechanically connected to one another. The mechanical connection can be in the form of a retaining edge 205 formed by the body of the container 12 around the insert 200 which effectively fixes the insert 200 with respect to the rest of the body 01. Alternatively, it is also contemplated that a "shortened adaptation" can achieved by the body 12 forming a thermo-elastic around the insert 200. A particular example of this shortened adaptation application could be the provision of a desiccant-laden insert 200 constructed of a polyethylene-based thermo-elastic and a container body 12 molded around it. from a polypropylene base thermoplastic. Upon cooling after being injection molded, polyethylene shrinks less than polypropylene under similar circumstances. Therefore, if a polypropylene body is injection molded around the polyethylene insert 200 that has previously been formed, or at the same time injection molded with the body of the container 12, the body of the polypropylene container 12 will shrink around the insert. polyethylene 200. The shrink fit method can be implemented whether the insert 200 is relatively small and located relative to the body of the container 12 or if the insert 200 has the shape of a lining configuration previously described 205. In any case , the body 12 of the externally formed container can be shrunk around the insert 200 if the thermoplastics of which the insert 200 and the body of the container 12 are approximately selected. The use of the retaining edge 206 and the method of adapting to the shrinking of fixing the insert 200 or liner 205 to the body of the container 12 is used mainly when the materials of construction of the insert 200 and body of the container 12 are not compatible. The two components will be considered incompatible if they do not automatically adhere to each other as a result of the manufacturing process. Alternatively, the insert 200 will be constructed of a material that attaches to the body 12 of the container 01 when the body 12 is placed therein. Therefore, a preferred method for constructing the insert 200 carrying the container 01 of the present invention is co-molding. That is, the primary body 12 of the container 01 is molded, while the insert 20 with high desiccant content is also molded. The two portions are co-molded since they are either simultaneously or sequentially molded by injection in a single process. The co-molding process results in the construction of a unified container body 12 in which the insert 200 is seamlessly combined with the body 12, in most cases, the insert 200 and the body of the container 12 adhere to each other. another as a result of a fusion of the base thermoplastics of which each is built on an interface between them. The fusion action takes place when the insert 200 and the body of the container 12 are each injected into the mold 10 sufficiently narrow with respect to time so that each at least is in a semi-molten state while in contact with one another . Alternatively, the heat from the thermo-elastic of a body 12 injected around the insert 200 may cause the contacted portions of the insert 200 to melt slightly and fuse with the thermo-elastic of the body 12 adjacent thereto. In each case, there will be a phase between the concentrated insert 200 with high desiccant content and the body of the container 12 in which the two construction materials are mixed to some degree creating a seamless interface and therefore unifies the container e01 outside the two components . As explained, in a preferred embodiment, the insert 200 with high desiccant content is located on the base or bottom 203 of the container 01. A surface of the insert 200 can be directly exposed to the interior 201 of the container 01 or the insert 200 can be completely encapsulated In addition, it is contemplated that the bottom portion 203 of the container 01 may be constructed exclusively from the thermo-plastic with high desiccant content if the reduced qualities of the material do not adversely affect the performance of the container 01. This may be the case if the container 01 will not be exposed to high pressures or rough handling. To produce said container 01, it is contemplated that the lower portion and the upper portion will be formed of thermoplastic of different desiccant concentration, ie thermoplastics of lower concentration of desiccant will be injected into the upper portion of the mold 10 and higher desiccant concentration will be injected in the lower portion. The thermo-elastic of the two portions will be mixed at one interface and melted in a used container body 12, as long as the base thermoplastics of each are compatible. Like the other injection processes, it is contemplated that each portion may be injected from separate injection ports 209 and 210 or the same port. As a result, the portions can be injected either sequentially or contemporaneously. In each case, the proportion of the container body 12 formed by each portion will be controlling by the amount of thermo-elastic injected in each. In any case, the thermoplastic in which the desiccant is retained is permeable to moisture to the extent that the moisture inside 201 of the container 01 can be transferred and stored in the desiccant. It is possible that the thermoplastic from which the insert 200 is manufactured may have a higher moisture permeability than that from which the remainder of the body 12 of the container 01 is constructed. In this case, the insert 200 may be enclosed within the container 01 by a thermoplastic permeable to the lower humidity of the container body 12. In this form, moisture can not easily be transferred from outside the container 01 to the interior. In view of the possibility of wanting to defer the moisture permeabilities in the insert 200 and the receiving body 12, it is contemplated that the two components 200, 12 can be constructed of different materials that are potentially incompatible. The process of the present invention in which the insert 200 is co-molded within the primary body 12 of the container 01 may vary. In a first mode of the molding process, it is contemplated that the mold 10 will move between two injection stations. An injection assembly which is generally designated by the difference regime 96 can be installed and removed from the molding frame 24. At a station, usually the first station, the insert 200 will be injection molded. In order to mold the insert 200, a ring-shaped barrier having a circumference that substantially equals the perimeter of a lower end of the matrix 48 will be provided. It is desired that the thickness of the insert 200 be approximately one-eighth of an inch , therefore the thickness or height of the barrier ring itself will be one eighth of an inch. As the injection assembly 96 is installed within the mold frame 24, the barrier ring is the main component. The ring is brought into contact with the lower surface of the matrix 48 forming a barrier into which the thermo-elastic can be injected. Then the thermoplastic is injected with high The desiccant concentration is injected into the interior of the ring thus forming the insert 200. The thermo-elastic with high desiccant concentration of the insert 200 can be injected at a temperature that is lower than the temperature and that the thermo-elastic of the container body 12 is inject The reduced temperature may be required so that the desiccant contained therein is not degraded. The need for red-hot temperature can be made obvious by using different and / or high-grade desiccators that are not susceptible to degradation within the normal temperature ranges of the injection process. When the insert 200 has cooled sufficiently to a point that it will maintain its shape after the removal of the barrier ring, the injection assembly 96 is removed from the mold frame 24, together with the barrier ring that is attached thereto. The insert 200 adheres to the lower surface of the matrix 48 and remains inside the mold 10. The mold 10 is moved to a second injection station similar to that previously described, but configured to the desiccant-free thermoeplast is injected into the cavity 114 with which forms the body of the container 12. The means for transporting the mold frame 24 between the stations is preferred to be a turntable 207 operating continuously between the two stations. During this second injection, the thermoplastic is injected to form the body 12 of the container 01 and optionally the lid 14. During this same step, the thermoplastic is also injected around the insert 200 that has been previously formed. In this form, portions of the insert 200 that could have been exposed to the exterior 202 of the container 01 are covered by the thermo-plastic without desiccant. The upper surface of the insert 200 is not covered by the thermo-plastic without desiccant since it remains in contact with the lower surface of the matrix 48. Through the insert 200 it is allowed to cool sufficiently to maintain its shape between the one and two stations and during the second injection, the second thermoplastic injection is made at a temperature sufficient to cause the two components 200, 112, to join as described herein. Depending on the conditions, it is possible that the highly concentrated insert 200 will melt sufficiently so that it bleeds into the body 12 of the container 01 located adjacent thereto. However, the amount of bleeding is not significant and does not degrade the performance of the outer thermopipes which gives the container 12 its strength and curability. In an alternative embodiment of the molding process, only one injection station is used, but two injection ports 209 and 210 are provided thereto. The thermopiped with high desiccant concentration forming the insert 200 is injected through one of the ports 109, while the non-desiccant thermoplastic forming the body 12 of the container 01 is injected through the other of the ports 210. In this process, the matrix 48 must move longitudinally away from the injection assembly 96 a distance equal to the thickness of the insert 200 that must be formed. Like the two station processes, the insert 200 is formed first and the body 12 of the container 01 is formed between them. In other aspects, the two processes are similar. It is anticipated that the absorption rate in the insert 200 can be controlled by the amount of surface area of the insert 200 exposed to the interior 201 of the container. If higher absorption rates are desired, more surface area of the insert 200 should be exposed. If a longer absorption process is desired, less surface area will be exposed. It is further contemplated that the absorption regime for the insert 200 can be controlled by encapsulation of the insert 200. If lower absorption rates are desired, then the insert 200 can be enclosed to greater degrees by the thermo-elastic that forms the body 12 of the container 01 and that It is less permeable to moisture. The absorption regime can also be controlled using different types of different moisture permeability regimes. Still further, the rate of moisture absorption by the insert 200 can be affected by other mixtures added to the thermoplastic. In particular, it has been found that the addition of polar organic compounds, such as "starch" to the thermo-plastic loaded with desiccant will greatly increase the absorption rate. The addition of polyvinyl alcohol (PVOH) has similar effects on the absorption rate of the loaded thermoplastic desiccant. In a particular example, the addition of five percent (5%) by weight of starch to polypropylene having ten percent (10%) of desiccant and without starch. The amount of moisture that can be absorbed by the insert 200 can be controlled in many ways. It is contemplated that the amount of moisture absorbable by the insert 200 may be effected by changing the concentration of the desiccant within acceptable ranges.; the greater the concentration, the greater the amount of moisture that can be captured.

In an alternative embodiment, the thermoplastic of which body 12 is constructed may also have retained desiccant and suspended therein, but at concentrations lower than insert 200. It has been found that the concentration of desiccant in the thermoplastic affects performance characteristics of the body. Molded container 01. As an example, it has been found that while the plastic will carry relatively high percentages of desiccant, desirable characteristics such as durability and resistance to ruptures can be degraded to higher concentrations of desiccant. It has also been found that the plastic can be combined with lower concentrations of desiccant without appreciably degrading the performance of the thermoplasic material in its molded and solid state. In a normal application, a relatively low concentration will fall within the range of five to fifteen percent (5-15%) of desiccant by weight to thermoplastic with a preferred concentration being approximately seven and a half percent (7.5%) . Additionally, for the purposes of the description made herein, desiccant-free thermoplastics may also be considered low concentration thermoplastics. Various concentrations of thermoplastic containing desiccant are commercially available in the form of pellets. Custom concentrations can be achieved by dry mixing desiccant pellets of higher concentration with lower concentration or desiccant pellets of thermoplastic. When mixed in appropriate proportions, any desiccant concentration lower than that of the high concentration desiccant pellets can be achieved. After the dry mixing process, the resulting mixture of pellets can be injection molded in the normal manner. In a preferred embodiment of the present invention, it is contemplated that the thermoplastic source for the insert 200 and that of the container body 12 may be mixed in a customary manner to achieve the respective desired desiccant concentrations of each. For the injection molding process, two supply hoppers can be provided; one having the thermo-plastic with high desiccant content from which the insert is formed and the other having a mixture of pellets of different concentrations that when melted in solution produce the thermo-elastic with amount of lower desiccant from which the body 12 of the container 01 is formed The insert 200 and the container body 12 are injection molded according to the different methods described herein. Although certain embodiments of the invention are illustrated, it will be appreciated that many modifications and variations of the present invention are possible in view of the foregoing teachings and within the scope of the appended claims without departing from the intended spirit and scope of the invention.
