Abstract
A disposable pillow made of recyclable and environmentally friend pulp through vacuum molding is provided. The pillow includes an open-bottomed hollow outer body and preferably an inner support having a plurality of upright ridge portions. The outer body has a top surface within which a smoothly curved recess is formed for comfortably supporting a patient's head. The inner support is adapted to be positioned in and below the outer body with upper ends of the ridge portions fitly contacting with and therefore firmly supporting an underside of the top surface of the outer body, preventing the top surface from downward collapsed when a patient's head is supported thereat.
Description




BACKGROUND OF THE INVENTION




The present invention relates to a disposable pillow, and more particularly to a disposable pillow made of pulp through vacuum molding for use by a person, especially a patient, for a short period of time in hospital to avoid possible infection by contact with survived bacteria on the hospital-supplied pillow.




While the biochemical industry makes rapid and high developments of many different medicines, there are more and more types of bacteria developed strong ability to resist such medicines and extremely severe environment. That is why there are so many diseases that are still beyond our medical control.




A hospital is, on the one hand, a place at where patients are treated and, on the other hand, a public place being most dangerously subjected to harmful bacteria. There are patients who are infected with other disease while they are in hospital to accept treatment for a previously infected disease. And this occurs in part due to the patient's weak physical conditions that subject the patient to infection with bacteria existing in the hospital.




Diseases propagate through many ways. A patient might be infected by air, direct contact, blood, secretion or food. And a patient in hospital would inevitably use bedclothes and pillows supplied by the hospital. These bedclothes and pillows are not absolutely bacteria-free even though they have been properly sterilized. Taking the pillow as an example, it is an item closest to the patient's mouth and nose and is therefore a most possible way by which the patient's digestive and respiratory systems are infected. It is therefore most preferable that a patient prepares at least the pillow for his or her own use in the hospital.




A pillow having been used by a patient in the hospital is naturally not suitable for bringing home after the patient is out of hospital. Such pillow should preferably be properly disposed in the hospital to avoid unnecessary infection. Therefore, it is preferable to provide an economical and disposable pillow for use in hospital to protect the patient from infection with other diseases without forming an economic burden to the patient.




SUMMARY OF THE INVENTION




It is therefore a primary object of the present invention to provide a disposable pillow that is made of recyclable pulp and is therefore low in cost and price.




Another object of the present invention is to provide a disposable pulp-molded pillow that is designed for economical use only by one patient during the period in hospital to avoid infection by contacting with a hospital-supplied pillow on which there might still be survived bacteria.




To achieve the above and other objects, the disposable pulp-molded pillow according to the present invention mainly includes an open-bottomed hollow outer body and preferably an inner support having a plurality of upright ridge portions. The outer body has a top surface within which a smoothly curved recess is formed for comfortably supporting a patient's head. The inner support is adapted to be positioned in and below the outer body with upper ends of the ridge portions fitly contacting with and therefore firmly supporting an underside of the top surface of the outer body, preventing the top surface from downward collapsed when a patient's head is supported thereat.




The outer body and the inner support of the pillow of the present invention are dried at high temperature when they are vacuum molded and then pressed with suitable machine to obtain smooth outer surface and dense and strong structure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




Please refer to

FIGS. 1 and 2

that are exploded and assembled perspective views, respectively, of a disposable pulp-molded pillow


10


according to the present invention. The pillow


10


mainly includes an outer body


20


and preferable an inner support


30


, both of which are made of pulp through vacuum molding. The outer body


20


is an open-bottomed hollow member defining a space therein. The outer body


20


includes a top surface


21


and peripheral walls. The top surface


21


of the outer body


20


is formed of a smoothly curved recess


22


adapted to support a patient's head thereat. The inner support


30


includes a plurality of upright ridge portions


31


and is adapted to be stably positioned in and below the outer body


20


with the upright ridge portions


31


upward projected into the space defined by the outer body


20


and fitly contacting their upper ends with an underside of the top surface


21


of the outer body


20


, as shown in

FIG. 3

, so that the top surface


20


of the outer body


20


is supported on the inner support


30


without becoming collapsed under the weight of the patient's head.




As mentioned above, both the outer body


20


and the inner support


30


are made of pulp through vacuum molding. In the process of molding, the primarily shaped outer body


20


and inner support


30


are dried to a predetermined extent under high temperature and then subjected to pressing with suitable machines, so that the outer body


20


and the inner support


30


have smooth outer surface and are dense and thick enough to provide the pillow an enhanced structural strength.




The disposable pulp-molded pillow


10


illustrated in

FIG. 1

represents a preferred embodiment of the present invention. In this preferred embodiment, the outer body


20


is substantially in the shape of a rectangle with the recess


22


located at a central area of the top surface


21


. A portion of the recess


22


at one side of the outer body


20


closer to the patient's body slightly inclines upward and outward to be higher than other areas of the recess


22


to provide a neck support


23


, so that the patient may comfortably support his or her neck on the slightly smoothly raised neck support


23


. In practical use of the pillow of the present invention, a suitable pillowcase or towel may be used to cover the top surface


21


of the outer body


20


to make the outer body


20


softer.




In another embodiment of the present invention shown in

FIG. 4

, there are a plurality of slightly raised dots


221


and


231


distributed over the recess


22


and the neck support


23


, respectively. Such raised dots


221


and


231


lightly press against and massage the patient's head and neck to improve the patient's circulation of blood at these areas. It is natural that such pillow is also useful to all other people in improving their circulation of blood at the head and the neck as well as their sleep quality. The raised dots


221


and


231


may be formed along with the outer body


20


with suitably designed molds.




Since the inner support


30


is designed to support the top surface


21


of the outer body


20


, lower edges of the inner support


30


must be lower than or, at least, flush with that of the outer body


20


when the inner support


30


is disposed in and below the outer body


20


. However, for integrity of the pillow


10


in its appearance, it is preferable to have an inner support


30


that is completely invisible from outside of the outer body


20


, as shown in FIG.


3


. Of course, it is also possible to omit the inner support


30


if the outer body


20


itself is structurally strong enough to support the patient's head alone.




When the pillow


10


is dried under high temperature in the process of molding, it is sterilized at the same time. Furthermore, since the pillow


10


is designed for use by only one patient in hospital, the patient can be assured that the disposable pulp-molded pillow


10


he or she uses is absolutely free from any bacteria from any other patients. That is, the pulp-molded pillow


10


is both physiologically and psychologically safe for use. And, since the pulp-molded pillow


10


could be manufactured with recyclable pulp at low cost, it would not form any extra burden to the patient to affect the patient's mood during treatment in hospital.




In brief, the disposable pulp-molded pillow


10


is an economical and practical product for safe use in hospital to reduce possible infection. And, since the pulp-molded pillow


10


is made of a recyclable material, it can be easily disposed after use simply by burning it without causing any pollution to the environment.
