Description

Disposable hygienic and hypoallergenic pillow insert protector

technical field

The present invention relates generally to bedding, and more particularly to pillow insert protectors.

Background technique

Pillow inserts used in homes, hospitals, hotels, rental properties (such as Airbnb), and other public living facilities can be allergens and A source of microorganisms (hereinafter referred to as "allergens" or "contaminants").

It is not customary to wash or frequently replace used pillow inserts, nor is it routine to wash or sanitize regularly throughout the life of a used pillow insert. The best way to do this is to use a regular pillowcase (also known as an insert protector or insert cover) to cover the pillow insert to protect it from contamination while sleeping on it. Periodically, wash regular pillowcases when they become soiled, become smelly, or are used by patients in hospitals or guests in public facilities. However, simply washing or changing to a clean regular pillowcase will not remove pre-existing allergens and microbes that inhabit and grow inside the used pillow insert. Traditional pillow covers are made of interwoven porous material which helps create an environment in which allergens can accumulate. This material allows moisture from the ambient air or the sleeper's breath, saliva, dandruff and dead skin cells to penetrate and accumulate in or on the pillow insert. Thus, it creates an environment that promotes the accumulation and growth of microorganisms and allergens such as dust mites. Additionally, conventional pillowcases are open on one end, have a zipper, or have alternative closures with inherent gaps and/or perforations created by the stitched assembly process. These gaps or holes provide opportunities for contaminants to enter the pillow and establish colonies in the pillow. Additionally, dead skin cells that penetrate and accumulate on the surface of the pillow core can become a source of nourishment for pollutants. In combination with porous materials, conventional outer shells allow the deposition of airborne pollutants on the pillow or allow the transfer of pollutants to pass freely between the user and the pillow.

Therefore, there is a need for a practical solution to preventing user exposure to pre-existing contaminants found on pillow inserts.

Contents of the invention

In general, the present invention provides a disposable hygienic and hypoallergenic pillow protector that prevents the transfer of contaminants from the pillow to the user.

By using custom materials and a reliably sealed outer cover, the disposable pillow protector completely isolates the user from the pillow and thus minimizes the risk of contamination by allergen-generating entities and leakage of allergens. To provide a protective barrier between the user and the pillow insert, the material must prevent the passage of moisture, pollutants, allergens and skin exfoliation, yet remain breathable and comfortable for sleeping.

As described further below, the disposable pillow protector is made using three or more layers of spunbond nonwoven filter fabric that is water impermeable, hydrophobic, antimicrobial, and breathable. This disposable pillow protector is manufactured using ultrasonic welding/bonding technology, which eliminates holes from sewing needles. Therefore, all seams of the disposable pillow protector are protected from allergens and moisture. This disposable pillow protector includes a compatible opening for inserting the pillow inside. The opening can be sealed with a strip of double sided tape covered with an easy peel backing paper bonded to the opening, thus making it ready to use and sealed after the insert has been inserted inside. This disposable pillow protector provides a sterile barrier around the pillow insert to prevent contamination and minimize allergen leakage.

Although this disposable pillow protector can be used by people of any age, there is a clear need for this product to protect vulnerable populations who are at risk of asthma, allergies and other respiratory conditions. This product can be used as a pillow insert protector or as a protective layer between a regular pillowcase and pillow insert. The open closure feature is intended for single use allowing easy wrapping around the pillow insert. This affordable, single-use, disposable pillow insert protector promotes personal hygiene and minimizes interaction with pre-existing microorganisms and allergens on the pillow insert. This single-use disposable pillow protector effectively reduces the chance of spreading respiratory infections among users sleeping on shared pillows, especially those provided by public facilities such as hotels.

An inventive aspect of the present disclosure is a method of making a hygienic disposable pillow protector, the method involving folding the pillow protector material to define a first surface and a second surface, and also to define a closed end and the closed end Opposite the open end of the step. Align the insert insert material to further define the two unsealed edges. The method then involves sealing the unsealed edges of the pillow protector material by ultrasonic welding or bonding to define two sealed edges extending from the closed end to the open end, thereby defining dimensions designed to enable insertion of the pillow insert into a disposable The opening in the insert protector. The method then involves applying a first double-sided tape and applying a second double-sided tape. The pillow insert can be inserted into the disposable pillow insert protector and the opening is sealed by forming a folded seam with the first tape and the second tape.

Another inventive aspect of the present disclosure is a disposable pillow protector comprising pillow protector material folded to define a first surface and a second surface, and further defining and opposite a closed end. , align the insert protector material to further define the two unsealed edges. The disposable pillow protector includes two sealed edges that are ultrasonically welded or bonded and extend from a closed end to an open end, thereby defining an opening dimensioned to enable insertion of a pillow insert into the disposable pillow protector . The disposable pillow protector also includes a first strip of double-sided tape and a second strip of double-sided tape.

Detailed ways

In general, as will be described in more detail below, a first aspect of the invention is a method for the manufacture of a single-use, disposable, hygienic and anti-allergic pillow insert (hereinafter referred to as a "disposable pillow insert"). )Methods. In the embodiments depicted in the figures, the disposable insert protector is constructed of three or more layers of spunbond nonwoven filter fabric or equivalent material. In the illustrated embodiment, the disposable insert protector is manufactured by ultrasonic welding/bonding techniques, rather than traditional stitching with needle and thread. Openings can be sealed with double-sided tape or strips of this tape. These components together form an integrated leak-proof barrier to surround the pillow insert, which effectively prevents or at least mitigates the transfer of allergens and microorganisms between the sleeper and the pillow insert. The beneficial properties of the finished disposable pillow inserts are confirmed by the American PPE testing standard ANSI/AAMI PB70 (level 2 or higher), but it is understood that this new method and the disposable pillow protectors produced by this method are not Limited to this test standard. Any other compatible industry-accepted test methods and standards may be used to demonstrate the hypoallergenic properties of the disposable pillow insert cover.

Reference will be made to the embodiments depicted in the accompanying drawings. In addition to the drawings, this specification discloses embodiments other than the drawings. Therefore, there is no intention to limit the invention to the single embodiment or embodiments disclosed herein. The present invention is intended to cover all alternatives, modifications and equivalents within the scope of this disclosure as defined by the appended claims.

1A and 1B show a first step of a method of manufacturing a disposable pillow insert denoted by reference numeral 10 according to an embodiment of the present invention. In this first step of the method, the disposable insert protector material 12 is folded and aligned, as shown, for the next step of the manufacturing method. In this embodiment, the disposable insert protector material 12 has a generally elongated rectangular shape. Disposable pillow insert protectors can be made to fit standard or custom pillow insert sizes.

The disposable insert insert material 12 has an inner insert insert backing layer 14 . The disposable insert protector 12 is folded to define a first surface 11 and a second surface 13 . As shown in these figures, the second surface 13 extends beyond the first surface at the opening. In other words, the second surface 13 has an upper protruding edge 15 provided as a designated space for a strip of double-sided adhesive tape to be bonded, as will be explained below. The width of this edge can be made compatible with the expected width of the double-sided tape. For example, align the underlying material to stick out a 2cm edge opposite the crease (opening), although another size edge could be used to match the width of any particular double sided tape being used. FIG. 1B also shows that the folding of the insert protector material 12 defines a closed end 17 and an open end opposite the closed end. Once the unsealed edges are sealed, the open end defines the opening 16 of the insert protector. By folding and aligning the insert protector material as shown in FIGS. 1A and 1B , two unsealed edges are defined.

Figure 2 shows the results of the next step of the method, where the two edges are firmly bonded and sealed using ultrasonic welding/bonding techniques to make them hydrophobic and anti-allergic. Sealing of the edges can be accomplished by alternative methods to make the disposable insert protector hydrophobic and hypoallergenic. This step of sealing the edges produces an opening 16 and two sealing edges 18 as shown in FIG. 2 .

Figure 3 shows the result of the subsequent step of applying two strips of industrial grade double sided tape covered with an easy release liner. In this embodiment, the upper strip 20 and the lower strip 22 are parallel and separated by a gap between the strips. The gap between the strips 20, 22 may be greater than the thickness of each individual strip shown in this figure, or another spacing may be used. The upper strip 20 may be positioned along the edge of the opening 16 as shown, although in another embodiment it may be spaced from the opening. Bonding these strips to the designated upper edge of the disposable insert protector material makes it ready for immediate use after inserting the insert inside. This easy leak-proof closure is easy for the user to seal the opening with a simple D-I-Y (Do It Yourself) folding process. This sealing of the opening can be achieved by alternative methods. Figure 3 also shows the completed disposable pillow insert ready for use by the user.

FIG. 4 is the disposable pillow protector after the pillow has been inserted through the opening 16 inside the disposable pillow protector. As shown in this figure, an easy release liner is in place to prevent contamination of the double sided tape strips 20, 22.

Figure 5 shows a disposable pillow protector with a pillow inside after the upper strip of double-sided tape has been folded down (with the backing paper peeled off) and the opening sealed. It should be noted that the insert is inserted into the insert protector before the upper strip 20 of the double-sided tape is folded down. Folding of the upper strip 20 creates an upper fold seam 24 (also referred to herein as a first fold seam, as will be explained below). Since the double-sided tape is intended for single use only, the sealed disposable insert protector should not be reopened until it needs to be discarded.

FIG. 6 shows the formation of the second fold seam by further folding the first fold seam onto the lower strip 22 . A first fold seam 24 is precisely adhered on top of the lower strip 22 of double-sided tape (with the backing paper peeled off) to further secure (ie, double seal) the pillow insert enclosed inside. Since the double-sided tape is intended for single use only, the sealed disposable insert protector should not be reopened until it needs to be discarded.

Figure 7 shows the front side of the disposable pillow protector without any folded seams to seal the opening, which is therefore the preferred surface on which to sleep. Since the double-sided tape is intended for single use only, the sealed disposable insert protector should not be reopened until it needs to be discarded.

Various inventive features and aspects are apparent from the foregoing description. By applying an ultrasonic welding/bonding method (rather than needle-based stitching) to pre-form the disposable pillow insert cover, all seams adjacent to the insert fold are sealed to make it hydrophobic and hypoallergenic. This method can be performed using an alternative seam sealing technique that does not puncture the material, protecting its protective barrier against allergens and moisture.

The application of built-in industrial-grade double-sided tape enables closure using a simple D-I-Y process, allowing the user to easily seal the opening after enclosing the pillow insert inside. This method of securing the encapsulated insert and making it hydrophobic and anti-allergic can be achieved using any alternative to D-I-Y closures, which completely seal the opening to ensure no moisture or allergens can enter or exit. This off-the-shelf closure, which helps maintain personal hygiene, enables the manufacture of a versatile and cost-effective single-use, disposable pillow protector.

In one embodiment, the disposable pillow protector material is constructed of three or more layers of spunbond nonwoven fabric that is designed or designed to be water impermeable, hydrophobic and breathable. Such composites of spunbonded nonwoven filter fabrics can be tailored with suitable combinations of polyurethane-based, polyethylene-based and polytetrafluoroethylene-based membranes with microporosity, but are not limited to other alternative composites with compatible properties. Thus, the disposable pillow insert made from the above spunbonded nonwoven fabric provides desirable hygienic properties.

The methods described herein enable the manufacture of disposable pillow protectors that avoid traditional stitching with thread and needles that result in numerous perforations and gaps. Due to the novel method of manufacturing this disposable pillow protector, it is impermeable to moisture, water and contaminants. Thus, it minimizes the amount of allergens, contaminants, moisture and microorganisms that are transmitted from the packaged insert to the user. By minimizing the outflow of pollutants and allergens from the encapsulated pillow insert, the user is protected from exposure that would exacerbate a respiratory or skin medical condition.

Similarly, disposable insert protectors minimize the amount of contaminants, bacteria, food sources, and moisture that enter the packaged insert from the user and the environment. This minimizes the formation or maintenance of an environment that sustains organisms such as bacteria, bed bugs, dust mites and other microorganisms.
