Application filed July 30, 1913. Serial No. 782,121.
To all whom t may concern:
Be it known that l, Dr. HERMANN Nun- Lnvonn, a citizen of the German Empire, residing at Mannheim, Germany, have invented cert-ain new and useful Improvements in Vafers for Encapsulating biedt cines, of which the following is a specification.
The invention relates to an improved wafer for facilitating the taking of unpleasantly tasted medicines or drugs in the form of drops. lt is well known that the taking of such medicines frequently causes vomiting and repugnance on the part of the patient, whereby the therapeutic effect of the medicine is rendered doubtful. For avoiding such mishaps capsules have been employed hitherto which contain the liquid medicine in convenient doses and in a form easily stored. Such capsules can however, only be made in factories or by pharmacists with special appliances.
The object of the present invention is to enable the production of such preparations in a forni free of unpleasant taste by the doctor, nurse or patient himself.
The invention will be more readily understood from the description of one convenient form illustrated by way of example in the accompanying drawings in which Figure l, is a plan of a wafer according to this invention. Fig. EZ is a section on the line 2-2 of Fig. l. Figs. 3 and 4c show a second form of the invention in plan and section on the line i-i of Fig. 3 and Figs. 5 and 6 illustrate a further form in sectional plan and sectional elevation on the line 6 6 of Fig. 5.
ln the drawing a designates an ordinary wafer of circular form. According to this invention such a wafer is provided with a center core or boss b adapted to take the liquid medicine or to soak it in.
In use the medicine to be taken is applied in drop form to the core 0r boss b. The liquid is absorbed and thereby retained. The ordinary wafer a is then nioistened with water and pressed over the core, that is to say, it is closed in, whereupon it may be swallowed. rlhe wafer thus forms a device which may be used at any time by the doctor, nurse or patient with the greatest simplicity and without any special practice or waste of time.
ln Figs. 3 and fi, the wafer a, is made of rectangular form, while the core 5, is pro- 'ided with a depression 5 and is arranged at the left hand edge of the wafer.
Jaccording to the form shown in Figs. 5 and (i, the wafer a, is provided with an upwardly bent edge a so as to provide a saucer shaped structure in which the core o is provided. The cover c, is placed over the saucer shaped wafer thus formed after the medicine has been dropped on to the core.
The size of the core and wafer may be as required and will of course be suited t0 the special conditions. Furthermore the core may be made of any other material than that of the wafer. rihe core may, if desired, be provided with an insoluble layer al of gelatin or the like in order to prevent the liquid medicine from percolating from the core on to the wafer proper.
The material to be used for making the wafer and the thickened absorbent portion (core) in general is the so-called wafer-substance, c'. e., a mixture of flour and water. However, other ingredients may be used as a substitute for the aforesaid material if there exist no objections in hygienic sense. Furthermore there is no departure from the spirit of my invention whether the said thickened absorbent portion is provided with a depression or not.
1. A device for encapsulating liquid medicines comprising a wafer carrying an attached thickened absorbent portion with a depression in the latter adapted to receive the medicine and a cover portion adapted to inclose and seal said thickened absorbent portion.
2. A device for encapsulating liquid medicines comprising a saucer shaped wafer carrying a thickened portion with a depression in the latter adapted to receive the medicine and a cover over said saucer shaped wafer for inclosing and sealing said thickcned absorbent portion.
3. A. device for encapsulating liquid medicines comprising a saucer shaped wafer, carrying an attached thickened absorbent portion with a depression in the latter adapted to receive the medicine, a nonabsorbent layer on the lower and lateral part of the said absorbent portion and a cover over said saucer shaped wafer for inclosing and sealing said thickened absorbent portion.
4. il device for encapsulating liquid name *no this specification in the presence of medicines comprising a Wafer carrying an two subscribing witnesses.
