Description

TECHNICAL FIELD

The present invention relates to a method for producing a blanket, and a blanket produced by the method and, more particularly, to a method for producing a blanket having a filler such as cotton batting included within the outer cover, and a blanket produced thereby, the method being capable of: sewing the outer cover of the blanket with the filler even at the outermost edge of the blanket to thus produce a blanket where the filler is stably fixed in the outer cover at the edge of the blanket while, in particular, enabling a rapid and easy production due to there being no need for an extra finishing process; and sewing the outer cover of the blanket with the filler even at the outermost edge of the blanket for the filler to be stably fixed in the outer cover at the edge of the blanket, thereby freely forming the design of the outermost edge of the blanket and enabling a pattern sewn in the middle of the blanket to be formed in a variety of patterns regardless of a gap with the outermost edge of the blanket.

BACKGROUND ART

A bedding, in general, consists of a blanket and a mattress. The aforementioned bedding and a pillow are collectively called a bedding set (a blanket, a mattress, and a pillow). The blanket is an essential item in the bedding set. According to the chapter 29 of the picture handbook published in the Korea dynasty, the pillow and the blanket are described as an embroidered pillow and sleeping clothes. A historic background on the aforementioned bedding set might be known from a record on the blanket and the pillow recited in the book “Item lists on blanket, mattress and pillow” published in the Chosun dynasty. The pillow excavated from an ancient tomb of the Backjae dynasty, the pillow of the Korea dynasty and the pillow excavated from the tomb of the general of Kim, Duk-ryung who was died in a prison during the Imjin war between the Chosun dynasty and Japan are almost same as the modern pillows. From this fact, it is possible to assume that the blanket, the mattress and the pillow are passed down from old times without any changes thereto.

As mentioned above, there are various kinds of blankets. Most of these blankets are constituted in a structure wherein the filler (this is called a cotton batting and is made of cotton wool, chemical wool, etc.) is filled in the outer cover (a raw fabric covering the exterior of the blanket).

PATENT DOCUMENTS

The Korean Patent Laid-open No. 10-2011-033371 (laid-open on Mar. 31, 2011) entitled “a blanket produced using a knitted fabric and a method for producing the same”.

The aforementioned patent document is directed to a blanket produced using a knitted fabric and a method for producing the same, wherein the blanket is produced in such a way that a knitted fabric produced by a circular knitting machine is sewed at a predetermined interval in a state where the layers of the knitted fabric is not pushed backward after an inner filler, for example, a cotton wool, etc. has been filled inside of the knitted fabric, thus forming a sewing line and cutting it into a unit raw fabric, and each corner of the unit raw fabric is cut, thus forming an opening part, and the unit raw fabric is fixed to an embroidery frame after a pipe has been inserted into the opening part at a lateral surface of the unit raw fabric so as to prevent any sagging or drooping of the unit raw fabric, and the thusly fixed unit raw fabric is sewed together with the inner filler, and then the fixing tongs and the pipe are removed, and each end thereof is cut off and is subjected to a finishing process. In this way, the blanket can be produced without any sagging and drooping or rolling-up of a short or long blanket in such a way that the raw fabric is cut off into unit raw fabrics, and the opening part is formed, and the pipe is inserted into each end and is fixed in place with the fixing tongs.

According to the aforementioned conventional method for producing a blanket (patent documentation), the outer cover is sewed and formed using a raw fabric which forms the outer cover of the blanket, and then a cotton batting, namely, a filler, is inserted into the outer cover, thus forming the exterior of the blanket, and a predetermined pattern is formed sewed in the middle of the blanket or the outermost edges of the blanket are subjected to a finishing process, thus finishing the blanket. In case of the blanket produced by the conventional producing method, the outer cover of the blanket and the inner filter are not firmly fixed at the outermost edges of the blanket. For this reason, the filler may move away from the edges of the blanket during the use of the blanket, so the outer cover and the filler may remain separated from each other.

Moreover, if a predetermined finishing process is prepared and carried out in order to firmly fix the outer cover and the filler to the edges of the blanket, the manufacturing cost may increase due to the additional work processes, and the manufacturing time, likewise, may increase.

If the outer cover and the filler are not firmly fixed in place at the edges of the blanket, it may be difficult to increase the interval at the outermost edges of the blanket to a predetermined extent when designing the patterns formed sewed in the middle of the blanket (if this interval is extended too much, the filler which is not fixed in place to the outer cover at the edges of the blanket may be likely to tangle in the middle of the blanket), and the designing of the patterns formed sewed in the middle of the blanket may be greatly limited. The designing of the outermost edges of the blanket may be also limited since it inevitably needs to consider the insertion of the filler or an additional finishing process, whereupon, the designing itself may be limited.

BEST MODES FOR CARRYING OUT THE INVENTION

The method for producing a blanket and a blanket produced by the method according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings. If it is judged that a known function or configuration may render the subject matters of the present invention unclear while the present invention is being described, the detailed description thereon will be omitted. The word “comprise” used throughout the specification as in “a predetermined unit comprises a predetermined component” means that unless otherwise stated, it may comprise another component, not excluding such component.

Referring to FIGS. 1 to 8, the method for producing a blanket according to an embodiment of the present invention may include, but is not limited to, a spreading step S1 wherein a filler 10 inserted inside a blanket is spread, and a first outer cover 20 and a second outer cover 30 adapted to form the upper and lower surfaces of the blanket are stacked and spread over a surface of the filler 10; a first sewing step S2 wherein an outermost sewing line 40 adapted to form an outermost edge of the blanket is sewed at the filler 10, the first outer cover 20 and the second outer cover 30 which have been stacked in sequence and spread in the spreading step S1; and an overturning step S3 wherein after the first sewing step S2, the blanket is turned inside out, and the filler 10 positions inside the first outer cover 20 and the second outer cover 30, whereupon the blanket can be quickly and readily produced, wherein the outer cover (the first outer cover 20 and the second outer cover 30) of the blanket and the filler 10 are sewed at the outermost edges of the blanket, and the filler can be firmly fixed in place at the outer cover at the edges of the blanket.

As mentioned in connection with the problems of the blanket produced by the conventional producing method, the blanket is produced by the conventional method in such a way that an outer cover is made through sewing by using a raw fabric which has been prepared to produce an outer cover of the blanket (the outer cover is made like an envelope by sewing all the sides except for only one side), and a cotton batting, namely, a filler, is filled into the outer cover, thus producing the blanket. In the thusly produced blanket, since the outer cover of the blanket and the inner filler are not firmly fixed in place, the filler may move out of the edges of the blanket during the use of the blanket, so the outer cover and the filler may remain separated or the filler may be tangled in the middle of the blanket. Moreover, in order to resolve the aforementioned problems, if an additional finishing process is carried out to firmly fix the outer cover and the filler at the edges of the blanket, the number of the work processes may inevitably increase due to the aforementioned additional work process, which may result in increased producing costs, and the blanket production may take longer.

Therefore, in the present invention, the blanket wherein the outer cover of the blanket and the filler can be firmly fixed in place at the outermost edges of the blanket by way of the improved producing method, can be produced quickly and readily through a simple process.

The spreading step S1 is a step wherein a filler 10, which is inserted into a blanket, is spread, and a first outer cover 20 and a second outer cover 30, which define the upper and lower surfaces of the blanket, are stacked and spread over one surface of the filler 10.

Namely, different from the conventional method wherein the outer cover is first made by way of sewing, and the filler is inserted into the outer cover, in the present invention, the filler 10 (the filler 10 represents a predetermined thing, for example, a cotton batting inserted into the blanket for the sake of heating effects and may represent a collective meaning of a cotton wool, a chemical wool or other cotton batting. In the present invention, the filler 10 is preferably a flat-shaped filler which is interconnected together and can be spread in a flat shape—more specifically, rather than the filler like duck down a feather of which remains isolated from each other, a filler is preferred, which is interconnected together like a cotton wool or a chemical wool and can be spread in a flat shape) inserted in the blanket, the first outer cover 20 and the second outer cover 30 are stacked in the sequence where they appear in the above description, and spread on the worktable (a). The outermost edges of the blanket, thereafter, are sewed at a time in the first sewing step S2, thus forming an outermost sewing line 40, and the outer cover of the blanket (the first outer cover 20 and the second outer cover 30) and the filler 10 are firmly fixed along the outermost sewing line and in place at the outermost edges of the blanket.

As illustrated in FIG. 1, the filler 10 inserted in the blanket is first spread on the worktable (a). As illustrated in FIG. 2, any of the first outer cover 20 which is intended to define the upper surface of the blanket and the second outer cover 30 which is intended to define the lower surface thereof is first spread on the spread filler 10. The first outer cover 20 (it will be assumed and described that the first outer cover 20 is first spread for easier understanding) which will be spread, should be disposed in such a way that the inner surface thereof intended to contact with the filler 10 is disposed toward the filler 10 and then contacts with the filler 10 (more specifically, as illustrated in FIG. 2, it is facing downward), and the outer surface thereof which will be exposed to the outside when the blanket is finished, is arranged to face in the opposite direction (more specifically, as illustrated in FIG. 2, it is facing upward). The reason for this configuration will be described in details later when describing the overturning step S3. In the next step, as illustrated in FIG. 3, the second outer cover 30, which is intended to define the lower surface of the blanket, is spread on the filler 10 and the first outer cover 20 which have been already spread in the sequence that they appear. In case of the second outer cover 30 which will be spread, the inner surface thereof which is intended to finally contact with the filler 10 in the next overturning step S3 is arranged to face upward, as in FIG. 3, and the outer surface thereof which is intended to be exposed to the outside when the blanket is finished, is arranged downward, as in FIG. 3, more specifically, it is arranged toward the first outer cover 20 and then is contacted with the first outer cover 20. The reason for this configuration will be described in details in the next overturning step S3. Meanwhile, in the step wherein the filler 10, the first outer cover 20 and the second outer cover 30 are spread and fixed on the worktable (a), as illustrated in FIGS. 1 to 3, the filler 10, the first outer cover 20 and the second outer cover 30 are firmly fixed in the spreading step S1 after they have been spread using fixing pins (b) which formed protruding from the corners of the worktable (a). The reason why all the corners are fixed after the filler 10, the first outer cover 20 and the second outer cover 30, more specifically, the first outer cover 20 and the second outer cover 30, have been already spread is that any bad sewing can be prevented, which may occur since the filler 10, the first outer cover 20 and the third outer cover 30, more specifically, the first outer cover 20 and the third outer cover 30, which are intended to be sewed together at a time during the sewing along the outermost sewing line 40 in the first sewing step S2, which will be described later, are prevented from concentrating in one direction or overlapping, whereupon the sewing along the outermost sewing line 40 can be readily carried out with respect to the filler 10, the first outer cover 20 and the second outer cover 30, more specifically, the first outer cover 20 and the second outer cover 30, which are intended to be sewed together at a time after the spreading has been carried out.

The first sewing step S2 is a step wherein the outermost sewing line 40, which defines the outermost edges of the blanket, is sewed at the filler 10, the first outer cover 20 and the second outer cover 30 which have been already stacked in sequence and spread in the spreading step S1.

The outermost sewing line 40 which defines the outermost edges of the blanket is sewed and formed, as illustrated in FIG. 4, by a mechanical method (or a manual work is also available) over the filler 10, the first outer cover 20 and the third outer cover 30 which have been spread and stacked in sequence on the worktable (a) in the spreading step S1. In case of the blanket which is produced along the sewed outermost sewing line 40 according to the present invention, since the outer cover (the first outer cover 20 and the second outer cover 30) of the blanket and the filler 10 can be firmly fixed at the outermost edges of the blanket, it can be possible to prevent the filler 10 from separating from the outermost edges of the blanket, not fixed in place, or getting tangled toward the middle of the blanket. Likewise, since the process for firmly fixing in place the outer cover (the first outer cover 20 and the second outer cover 30) of the blanket and the filler 10 can be quickly and readily carried out through a single procedure wherein the outermost sewing line 40 is sewed, whereby the blanket of the present invention can be quickly and a readily produced through a simplified procedure.

In the first sewing step S2, an opening part 50 wherein the outermost sewing line 40 is not sewed may be formed at a part (for example, a predetermined portion of a surface of one side in case of the rectangular blanket as in FIG. 4) of the outermost edges of the blanket, so the overturning step S3 can be carried out, wherein the blanket is turned inside out through the opening part 50 after the first sewing step S2. More specifically, since the outermost sewing line 40 should not sew and close the whole outermost edges of the blanket for the overturning step S3 to be carried out, the opening part 50 wherein the outermost sewing line 40 is not sewed, is formed at a part of the outermost edges of the blanket in the first sewing step S2.

The overturning step S3 is a step wherein the blanket is turned inside out after the first sewing step S2, so the filler 10 can position inside the first outer cover 20 and the second outer cover 30. More specifically, the blanket is turned inside out after the first sewing step S2 through the opening part 50 by the manual or mechanical method in a state where the outer cover (the first outer cover 20 and the second outer cover 30) of the blanket and the filler 10 have been firmly engaged together (fixed) after the outermost edges of the blanket except for the opening part 50 are sewed by the outermost sewing line 40 in the first sewing step S2. Here, the blanket should be turned inside out along the portions (if it is stacked in the sequence of the filler 10, the first outer cover 20 and the second outer cover 30, the portions between the second outer cover 30 and the first outer cover 20 may become an inverting center) between the first outer cover 20 and the second outer cover 30 from the filler 10, the first outer cover 20 and the second outer cover 30 which have been stacked in sequence. In the thusly inverted state, the first outer cover 20 and the second outer cover 30 can be exposed to the outside, and the filler 10 can position inside the first outer cover 20 and the second outer cover 30, thus defining the shape of the blanket as illustrated in FIG. 5. The first outer cover 20 which is spread over the filler 10 in the spreading step S1 will be spread in a state where the inner surface thereof contacting with the filler 10 is facing downward, and the outer surface thereof which is intended to be exposed to the outside when the blanket is finished, is facing upward, and on the contrary, the second outer cover 30 which is spread over the first outer cover 20, will be spread in a state where the outer surface thereof which is intended to be exposed to the outside when the blanket is finished, is facing downward, and the inner surface thereof contacting with the filler 10 is facing downward. If the blanket is turned inside out in the overturning step S3 along the portions between the first outer cover 20 and the second outer cover 30, namely, the portions where the outer surface of the first outer cover 20 is facing the outer surface of the second outer cover 30, the outer surfaces of the first outer cover 20 and the second outer cover 30 can be exposed to the outside after the blanket has been turned inside out, and the filler 10 can position inside the first outer cover 20 and the second outer cover 30, thus obtaining the shape of a finished blanket as illustrated in FIG. 5.

A second sewing step S4 for sewing the opening part 50 may be carried out after the overturning step S3.

In the second sewing step S4, the whole outermost edges of the blanket are closed as illustrated in FIG. 6, and the outer cover and the filler can be firmly fixed in place at the whole outermost edges of the blanket after the shape of the finished blanket has been formed, wherein the outer surfaces of the first outer cover 20 and the second outer cover 30 are exposed to the outside in the overturning step S3, and the filler 10 is inserted in the first outer cover 20 and the second outer cover 30, and the opening part 50 wherein the outermost sewing line 40 is not sewed at a predetermined portion for the sake of the overturning step S3 has been sewed and finished.

According to the method for producing a blanket, the outer cover (the first outer cover 20 and the third outer cover 30) of the blanket and the filler 10 are firmly fixed in place together through the first sewing step S2 and the overturning step S3 after the filler 10, the first outer cover 20 and the second outer cover 30 of the blanket have been spread in sequence, by means of which it can be possible to prevent the filler 10 from separating, not fixed at the edges of the blanket, and getting tangled toward the middle of the blanket. In particular, the blanket can be quickly and readily produced through the simplified processed.

In addition, according to the method for producing a blanket, a third sewing step S5 may be carried out, wherein a variety of patterns can be sewed and formed in the middle of the blanket in a state where the filler 10 have positioned inside the first outer cover 20 and the second outer cover 30 through the overturning step S3.

The third sewing step S5 is a step wherein the final type and design of the blanket can be finished after a variety of patterns as illustrated in FIG. 7 are sewed in the middle of the blanket in a state where the filler 10 has positioned inside the first outer cover 20 and the second outer cover 30, which were subjected to the aforementioned procedures, and the outer cover and the filler have been firmly fixed in place at the outermost edges of the blanket. According to the present invention, since the outer cover of the blanket and the filler are firmly sewed and fixed in place at the outermost edges of the blanket, the filler can be firmly fixed in place at the edges of the blanket, whereby the outermost edges of the blanket can be freely designed (in the conventional technology, since the filler 10 is not firmly fixed at the outermost edges of the corners of the blanket should be formed rounded large so as to prevent the filler 10 from getting tangled or concentrating in a predetermined direction, which means a limit to the designing of the blanket). Moreover, the patterns sewed in the middle of the blanket can be made into a variety of forms in the third sewing step S5 irrespective of the interval to the outermost edges of the blanket. More specifically, if the intervals between the outermost edges of the blanket and the sewing line in the middle are too much spaced apart, the filler 10 which has not been fixed at the outermost edges may get tangled or concentrate in the middle of the blanket. For this reason, it was impossible to form the sewing line sewed in the middle of the blanket at a predetermined interval to the outermost edges of the blanket in order to prevent the filler, which was not fixed at the outermost edges of the blanket, from getting tangled or concentrating in the middle of the blanket. In the third sewing step S5 of the present invention, a variety of patterns can be freely sewed in the middle of the blanket at various intervals without any limit, whereby the whole shapes and designs of the blanket can be determined freely.

As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described examples are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
