Description

Disposable sweat pad Technical field

The present invention relates to a sweat absorbent pad, and more particularly to a disposable absorbent pad for a hat. Background technique

In many strenuous activities, especially outdoor activities, such as baseball, horse riding, riding a motorcycle, or wearing a helmet, people often wear hats for safety or convenience. The hats described in this application include soft hats such as baseball caps, as well as rigid hats such as protective caps or helmets. It is often caused by hot weather, or a lot of sweat from the head, especially the forehead, due to strenuous exercise. Sweat will flow to people's faces and flow from the forehead to the eyes. People wearing hats, especially those who are performing prescribed actions or nervous operations, such as horseback riding and motorcyclists, often have no time to stop their activities to wipe off sweat. When sweat flows into the eyes, it can cause eye discomfort and blurred vision, affecting people's normal activities and even causing danger. Moreover, excessive sweat flow can make people feel uncomfortable and distracted to sweat, which is especially dangerous for people who operate high-speed machines.

For this reason, most hats, especially helmets, are provided with removable or permanently fixed sweat pads. Usually, these sweat pads have a weaker ability to absorb sweat, and it is not possible to ensure that sweat does not flow into the eyes for a long time. In addition, after repeated use, the sweat pad is soiled, wet and sticky.

Therefore, people designed a disposable sweat pad to try to solve the above problems.

In U.S. Patent No. 5,317,761, the entire disclosure of which is incorporated herein by reference. The sweat-absorbing strip has a limited ability to absorb sweat, and is susceptible to wet stickiness due to direct contact between the human body and the sweat-absorbing material. The straight shape of the sweat strip does not fit well with the hat.

Another straight strip of absorbent pad is disclosed in U.S. Patent No. 6,477,715, which is incorporated herein by reference. In addition, it can only be made into a straight strip with both ends open.

HAHN DAVID S (US) was awarded in 2003; U.S. Patent No. of HAHN KIM Y (US) et al. 6,738,985 discloses a curved sweat pad that fits the shape of the hat more closely. However, the sweat pad does not have a top layer, and only the sweat absorbing material layer and the adhesive layer are included.

In addition, when the amount of sweat is large, sweat may reach the inside of the cap through the sweat-absorbing material or re-penetrate the surface layer, thereby soiling the hat and leaving an odor. None of the above prior art sweat pads can effectively solve this problem.

Therefore, there is a need for a disposable sweat pad that is simple in construction, low in cost, and that absorbs a large amount of sweat and is comfortable to wear, and that can be attached to the cap conveniently and snugly, and does not stain the cap after use, and Easy to remove.

A specific embodiment of the absorbent pad of the present invention is shown in Figs.

Figure 1 shows an exploded perspective view of the sweat absorbent pad prior to assembly. As can be clearly seen from the figure, the disposable sweat pad comprises, in order, a water-permeable top layer 1; a sweat-absorbing layer 2 on the inner side of the surface layer for efficiently absorbing sweat; and a sweat-impermeable barrier layer 4 _An adhesive layer 4, disposed on the outer side of the barrier layer 3, attaching the sweat pad to, for example, the inside of the cap, and allowing the sweat pad to be easily removed from the cap after use; and the peelable protective layer 5 , covered on the adhesive layer 4, and peeled off from it before use.

The top layer 1 can be made of a soft nonwoven fabric. The sweat-absorbing layer 2 can be made of a dust-free paper or a polymer water-absorbing material, and can also include a layer of dust-free paper and a layer of polymer water-absorbing material. In particular, when the sweat absorbing layer 2 is made of a polymer absorbing material, the polymer water absorbing material can firmly lock the absorbed moisture and prevent it from oozing out from the surface layer, so that the surface layer feels more dry. The barrier layer 3 can be made of a watertight waterproof material such as polyethylene (PE) or polyurethane (PU). The adhesive layer 4 can be formed of a pressure sensitive adhesive. Other suitable materials may also be used to form the layers. The planar shape of the disposable absorbent pad after manufacture is shown in FIG. As clearly shown in Fig. 2, a sealing edge 6 is formed at the periphery of the facing layer 1, the sweat layer 2, and the barrier layer 3. The sweat absorbing pad is generally rectangular in shape, except that its two opposite long sides 7 and 8 have an arcuate curve and are curved in the same direction to fit, for example, the shape of the inner portion of the cap.

Figure 3 is a cross-sectional view of the disposable absorbent pad after manufacture, clearly showing the cross-section of the sealed layers and the sealing edges.

As can be understood, the barrier layer 3 prevents perspiration from permeating from the sweat layer 2 to the outside thereof, thereby separating sweat and preventing the hat from being soiled. In addition, the sealing edge 6 also prevents sweat from seeping from the periphery.

The sealing edge 6 can be formed by gluing or printing the thermal cover layer 1, the sweat layer 2 and the barrier layer 3. The sealing edge 6 can also be formed only by the sealing of the facing layer 1 and the barrier layer 3, excluding the sweat-absorbing layer 2, but merely enclosing the sweat-absorbing layer 2 on the facing layer 1, the barrier layer 3 and their sealing edges. Between 6.

Next, a method of manufacturing the sweat absorbent pad of the present invention will be described. The following steps can be carried out continuously on the automatic line.

First, strips each including a top layer 1, a sweat layer 2, and an anti-seepage layer 3 are prepared. These strips are continuously fed, and an adhesive material such as a pressure sensitive adhesive is applied to the surface which will become the contact surface between the layers during the feeding process. The strips of each layer are laminated in the order of the top layer 1, the sweat layer 2, and the anti-seepage layer 3 to form a composite strip. The composite strip will become the main portion of the absorbent pad.

The composite strip is fed into a rolling molding machine. The molding press presses the layers of the strip so that they are firmly bonded and formed to a suitable thickness, and at the same time, the sealing edge 6 of the desired shape is embossed on the strip. The stamper of the molding press can be made to press the sealing edge 6 to be thinner than the center portion of the strip (as shown in the cross-sectional view of Fig. 3).

Applying a pressure sensitive adhesive to the outer side of the barrier layer 3 to form the adhesive layer 4, and then cutting the peelable protective layer 5, such as a backing protective paper, into a suitable length, and attaching it to the adhesive layer 4 on.

Finally, the strip with the adhesive and protective paper is fed to the die-cutting machine. The die cutter of the die cutting machine has a shape similar to that of the sealing edge 6, and the strip is cut along the shape of the sealing edge to form a separate absorbent pad.

It should be pointed out that the above production process is automatically and continuously completed on the continuous feeding machine, so the whole production process is suitable for mass production, and economical and sanitary.

As can be appreciated, the present invention can be embodied and implemented in other specific forms without departing from the Principle and substance. For example, the adhesive layer can also be replaced by other attachment means, such as commonly used buckle materials. As another example, the length, curved shape, and thickness of the sweat pad can be determined according to the different shapes and needs of the caps used. For example, the materials used in the various layers of the absorbent pad and the method of sealing thereof can also be selected as needed. Further, the method for manufacturing the sweat absorbent pad can also select a desired process and a processing method as needed. For example, the pressure-sealing can be directly performed without applying a glue, or the peripheral portion of the sealing edge can be glued only. And only the peripheral portion is pressed.

The embodiments described herein are intended to be illustrative, and not restrictive, and the scope of the invention is defined by the appended claims rather All variations, substitutions and modifications within the scope of the invention are intended to be included within the scope of the invention.
