Description

  The present invention relates to a substitute tuft applicator in which a hair end is embedded in a U-shaped thermoplastic member.

  In the case of U shape, the bristle portion that connects both legs may be straight or curved. When attached to a person's head, the hair is sandwiched between the U-shaped or V-shaped legs, and then the member is heated using ultrasonic or heating tweezers until the thermoplastic becomes soft or melts. Is done. In order to complete this fusion, the bonded area is usually wrapped or folded between the fingers before the start of cooling in order to better embed the own or false hair in the adhesive. However, this method greatly depends on the dexterity of the barber's hand, and the fusion is often incomplete, so that the substitute hair is peeled off after several times the own hair is combed.

  Accordingly, an object of the present invention is an applicator that guarantees a secure connection between the hair and the own hair without requiring the special skill of a skilled person to apply the hair.

The above object is achieved by an applicator characterized by a matrix having at least one notch for receiving a U-shaped member in the width direction and a plunger movably guided to the notch of the matrix. Achieved.

  By means of an applicator consisting of a plunger and a matrix, the U-shaped member is finally deformed into a compact, elongated three-dimensional form in which both the hair and the hair are fully embedded at the ends. When inserting the own hair into the U-shaped member, the applicator is placed on the own hair so that the U-shaped member is positioned in the notch of the mother die. Thereafter, the member is plastically deformed and compacted (with or without heating) by pushing the plunger into the mold. Of course, only the relative movement between the plunger and the mother die is important. That is, similarly, the mother die can be pressed against the plunger.

It is preferable that the bottom of the notch and the tip of the plunger have different contours, and when the plunger is completely inserted into the notch , a prismatic empty space is defined. In that case, after attaching the substitute tuft to the own hair, the portion of the thermoplastic member has a prismatic shape.

  When the contours of the plunger and the bottom of the notch are straight or flat, the thermoplastic bonded body has a quadrangular prism shape. On the other hand, when the contour is curved, the cross section becomes a circular or oval cylindrical shape. The contours of the bottom of the plunger and the notch may be different from each other, for example, one is straight and the other is curved. Incidentally, it has been found that it is preferable to form one or both contours in a wavy or zigzag shape. The primary decisive factor for contour selection is the desired (and ultimately invisible to) outside appearance of the combination considering the desired hairstyle.

Advantageous to have a bottom portion and a plunger tip portion of the notch is, the mirror-like contour having a concave curvature in the movement direction and mother die width direction and the width direction in the same direction of the plunger of the plunger (landscape) I know that. When pressed against the space between the bottom of the notch and the tip of the plunger, the thermoplastic joint between the hair and the hair is essentially a cylindrical shape with a circular or elliptical torso. It has the shape of This shape originally caused the U-shaped member to be greatly squeezed and deformed at the end rather than at the center, so that in the fusing and pressing process, the hair was more than in the case of a prismatic or cylindrical fusion bond. Is more strongly covered by the thermoplastic member. At that time, it has been found that it is preferable that the bottom of the notch and the edge of the concave curved portion at the tip of the plunger have straight portions in the same direction as the width direction of the plunger. By such contour formation, the completed adhesive body covers the ends of the fur or the own hair in the vertical direction, and swells at the center to have a thick portion. Therefore, such a form of bonding is hardly noticed even if it is carefully observed if a transparent thermoplastic member is used as usual.

  A particularly simple and therefore advantageous embodiment of the applicator is that the matrix has a generally bowl-like shape consisting of long and short legs, the notch is in the short leg and the plunger is the long leg. It is to be guided along the short leg-facing side.

  Finally, it is preferred that the plunger and the master die be insertable into the operating and heating device, so that conventional related (generic) tools can be used.

  In order to ensure that the substitute hair is attached to the person's head substantially automatically and thus quickly, the notch of the master mold is juxtaposed for the hair corresponding to the shape of the notch Advantageously, a groove extending transversely with respect to the direction of movement of the plunger can be passed through which a magazine with a plurality of intakes can be pushed.

  In this embodiment, it is possible to fill a magazine with a plurality of substitute hairs by inserting the substitute hairs into the intake port with the U-shaped member. Therefore, by continuously pushing in the magazine, each intake port becomes flush with the notch of the master mold, and at that position, each substitute tuft and the self-inserted hair are inserted in advance. Bonding with hair is performed. In that case, all or a part of each intake port similarly functions as a notch. That is, all or part of the plastic deformation of the U-shaped thermoplastic member is directly performed in the intake port. Therefore, if the operation and heating device is equipped with a staged feeder for the magazine, it is preferably compatible with the present invention.

  In one embodiment, the master mold has at least one other similar cutout, all cutouts are juxtaposed at intervals corresponding to the intakes, and the plunger is a number corresponding to the number of cutouts. The plunger finger is provided. This clearly increases the capacity of the device according to the invention and makes it easier to handle.

  Next, the present invention will be described in more detail with reference to embodiments shown in the drawings.

  The applicator 1 (FIGS. 1 and 2) according to the present invention comprises a master mold 2 and a plunger 3. The mother mold has a substantially bowl shape composed of long legs 4 and short legs 5. The short leg 5 is provided with a groove-shaped notch 6. The plunger 3 is guided along the side of the long leg 4 facing the short leg 5. The plunger 3 and the bottom of the groove-shaped notch 6 can have arbitrary contours 7a and 7b. In the case illustrated in FIG. 1, the contour 7a of the plunger 3 is curved. On the other hand, the outline 7b at the bottom of the notch 6 is flat. On the other hand, in FIG. 2, both the outlines 7a and 7b are curved.

The substitute tuft 8 is provided with a U-shaped thermoplastic member 9 in which the end of the artificial hair 10 is embedded. At that time, it is shown that the U shape has a curved bridging portion that connects both legs. However, it may be a straight bridge. In order to attach the substitute hairs 8 to the own hairs 11, the ends of the hairs 11 are inserted into the U-shaped member 9, and then the U-shaped member 9 is fitted into the notch 6 of the mother mold 2. The plunger 3 is pushed into the notch 6 of the mother die. At that time, the applicator is heated, and the U-shaped member 9 is plastically deformed, whereby the fleece 10 and the own hair 11 are fused. Applicator comprising a plunger 3 and the matrix 2 which is a preferred embodiment, can be fitted into the corresponding operation / heating device 12 (FIG. 5).

  In the embodiment of the present invention shown in FIGS. 3 and 4, the notch 6 and the plunger 3 of the mother die 2 are moved in the direction of movement of the plunger (see arrow) or the relative movement of the plunger 3 and the mother die 2. It has a substantially mirror-like contour 7a or 7b curved in a concave surface both in the direction and in the lateral direction. At that time, the side curved portion of the concave curved portion extending in the lateral direction has shifted to the segment 7c substantially perpendicular to the moving direction. The bonded hair 10 (FIGS. 1 and 2) and own hair 11 (FIG. 2) completed after the crimping process is a generally cylindrical cylinder with a torso that is particularly proven in terms of appearance and quality of fusion. It has a shape of shape.

In the case of the embodiment of the applicator 1 shown in FIG. 5 and fitted in the operating and heating device 12, the short leg 5 of the mother die 2 is cut across the notch 6 and the width direction of the plunger 3 (mother die). The groove 13 extending in the width direction is penetrating therethrough. A magazine 14 having a plurality of (for example, 10) juxtaposed intake ports 15 corresponding to the shape of the notch 6 can be pushed into the groove 13 . The portion of the U-shaped member 9 of the substitute tuft 8 is inserted into the intake port 15. The operating and heating device 12 may comprise a stepped feeder (not shown).

  When the applicator shown in FIG. 3 is used, the hair tress 8 is first attached to the magazine 14 and then fitted into the groove 13. By continuously pushing in the magazine, the intake 15 reaches the notch 6 together with the inserted member 9, and at the same time takes over all or part of its function. At this position, the self-hair tress is inserted into the open U-shape of the member 9, and then the plunger 3 or the mother die 2 is operated to move relative to each other, so that the artificial hair and the self-hair are fused. Is done. After the thermoplastic prismatic or cylindrical combination is removed from the notch 6 of the master block 2 or the respective intake 15 of the magazine 14, the magazine 14 is pushed in by one of the intakes 15 so that Can be fused.

  FIG. 6 shows the present invention in which a plurality of notch portions juxtaposed at intervals corresponding to the intake ports are provided in the mother die, and the plunger also has a number of plunger fingers corresponding to the number of notch portions. The deformation | transformation form of the applicator by is shown. Since these plunger fingers have the same shape as the notches, a plurality of tufts can be fused simultaneously. At that time, the amount of movement of the magazine is of course adapted to the number of notches.

It is the schematic perspective view seen from the diagonal in the open state of the applicator by this invention. It is a figure of the closed state of the same applicator. FIG. 2 is a partial view of FIG. 1 of a variation of the present invention. FIG. 4 is a cross-sectional view taken along line IV-IV in FIG. 3. FIG. 5 is a schematic perspective view of another embodiment of an applicator according to the present invention including an operation / heating device, seen from an angle. FIG. 6 shows yet another variation of the applicator according to the present invention.
