1. Field of the Invention
The present invention relates to a stuffed toy, especially to a cloth stuffed toy having a cloth body and a polyurethane (PU) stuffing filled in the cloth body and a method for producing the cloth stuffed toy.
2. Description of the Prior Art(s)
Stuffed toys are soft throughout, resilient and squeezable and are capable of being used as toys for pets to play, chew, and bite.
With reference to
To overcome the shortcomings, the present invention provides a cloth stuffed toy and a method for producing the cloth stuffed toy to mitigate or obviate the aforementioned problems.
The main objective of the present invention is to provide a cloth stuffed toy and a method for producing the cloth stuffed toy. The cloth stuffed toy has a cloth body and a PU stuffing formed by a polyurethane foam material fully filled in and adhered to the cloth body. The method for producing the cloth stuffed toy has a cloth body preparing step, a polyurethane foam material filling step and a foaming process performing step.
As the PU stuffing is securely bonded to the cloth body and is not easily fragmented, the cloth stuffed toy has advantages in providing a safety stuffed toy. Besides, during the foaming process of the polyurethane foam material, the polyurethane foam material spontaneously and extensively spreads inside the cloth body to facilitate stuffing the body effectively.
Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
With reference to
Depending upon entertaining effects to be achieved, the cloth body 11 may be formed as an animal or any shape of novelty, such as a ball, a vegetable, food or the like, is formed by attaching edges of at least one piece of cloth and has an interior chamber defined in the cloth body 11. The edges of the at least one piece of cloth that forms the cloth body 11 are attached to one another by sewing, high frequency welding or the like. In the preferred embodiment, the cloth body 11 is formed as a gear. Due to the nature of being soft and fluffy, cloth is commonly used as a material to make a harmless exterior part of a stuffed toy.
The injection orifice 13 is formed through the cloth body 11.
The PU stuffing 12 is formed by a polyurethane foam material through a foaming process in the interior chamber of the cloth body 11 and is adhered to an inner wall of the cloth body 11. The polyurethane foam material is injected through the injection orifice 13 into the interior chamber of the cloth body 11. As the PU stuffing 12 is soft and resilient together with the soft and fluffy cloth body 11, the whole cloth stuffed toy is also soft, resilient and fluffy from inside out. As the PU stuffing 12 formed by the foaming process completely fills the interior chamber of the cloth body 11 and is adhered to the inner wall of the cloth body 11, the cloth body 11 and the PU stuffing 12 are securely bonded.
The whistle 14 is mounted in the interior chamber of the cloth body 11 and corresponds to the injection orifice 13. When the cloth stuffed toy is squeezed, air inside the cloth stuffed toy is blown through the whistle 14 and the injection orifice 13 to make a sound.
With further reference to
A cloth body 11 preparing step 21: preparing the cloth body 11 of the cloth stuffed toy having the interior chamber defined in the cloth body 11 and the injection orifice 13 formed through the cloth body 11;
A polyurethane foam material filling step 22: injecting the polyurethane foam material into the interior chamber through the injection orifice 13 of the cloth body 11;
A foaming process performing step 23: performing the foaming process of the polyurethane foam material until the polyurethane foam material fills the interior chamber and is adhered to the inner wall of the cloth body 11; and
A whistle mounting step 24: inserting the whistle into the interior chamber through the injection orifice 13 of the cloth body 11.
The cloth stuffed toy as described has the following advantages. The soft and fluffy cloth body 11 and the soft and resilient PU stuffing 12 do not give rise to harmful effects if bitten, chewed or played. Furthermore, unlike artificial cotton fibers, as the PU stuffing 12 is adhered to the cloth body 11, the PU stuffing 12 is not easily fragmented into small pieces that would be spread around and inhaled or eaten by people or animals. In addition to having cushioning, anti-abrasive, damping capacities and being flexible, the polyurethane foam material is a polymer with low toxicity. As a consequence, the cloth stuffed toy as described is safer than conventional stuffed toys filled with the artificial cotton fibers when bitten, chewed or played.
As for the method for producing the safety stuffed toy, during the foaming process of the polyurethane foam material, the polyurethane foam material spontaneously and extensively spreads inside the interior chamber of cloth body 11 to facilitate stuffing the cloth body 11 in an effective way.
Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and features of the invention, the disclosure is illustrative only. Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
