Description

The present invention relates to an application spatula for a viscous material such as an adhesive having a base end side as a gripping portion and an application portion formed on a distal end side.

As this type of application spatula, an adhesive spatula disclosed in Patent Document 1 is known.
This application spatula uses a configuration in which a thin flat plate is gradually thinned from the central part toward both ends in the longitudinal direction, and serrated irregularities are formed on both end edges to form an application part. is there.

Recently, non-solvent adhesives have been widely used for health reasons, and one-component moisture-curing adhesives have attracted attention.
This adhesive will begin to cure when exposed to moisture. In the case of household adhesives that are often used intermittently, if the opened tube is left for a long period of time, it will be difficult to reuse the adhesive, or work to remove the hardened part before use Inconvenience such as being forced to occur will occur.
For this reason, the capacity of the adhesive once opened is reduced so that the service period of the adhesive does not extend for a long time, the tube filling it is downsized, and the application spatula packaged accordingly is also downsized.

The above-mentioned known spatula, if it is long, if it is shortened according to a small household adhesive tube, if it is gripped by hand, the serrated irregularities will face the palm side, There is a risk of damage to the palm during application.
In addition, when the side to which the adhesive is applied is changed to the grip portion, the adhesive adheres to the hand, and when temporarily placed on the desk, the adhesive adheres to the desk.

Japanese Patent Laid-Open No. 11-80675

The present invention is a coating spatula for a viscous material such as an adhesive having a base end side as a gripping portion and a coating portion on a distal end side, and the viscous material remaining in the coating portion adheres to a hand or a desk during a coating operation. It is an object to make it possible to temporarily place a spatula while avoiding it.

The first technical means for solving this technical problem is: a) a through hole is provided between the gripping part and the coating part, and b) a movable plate is arranged inside the through hole, and c) a movable plate. Is pivoted around the periphery of the through-hole and can be bent outward. D) A locking portion is provided in the vicinity of the pivot to regulate the return of the movable plate, and e) the gripping portion is applied to the coating portion. It was made heavier.
The second technical means is that the movable plate is pivotally supported on the application part side or the grip part side of the through hole.
The third technical means is that the thickness of the central part side of the gripping part is made larger than that of the other part, and the fourth technical means is that the thickness of the left and right side edges of the gripping part is changed to the other part. It is larger than the part.
A fifth technical means is that a plurality of application surfaces having different application widths are formed in the application part.

In the first technical means, a through hole is provided between the gripping part and the application part, and a movable plate is arranged inside thereof. Since the movable plate is pivotally supported so that it can be bent outward, that is, outside the spatula surface, when the movable plate is pressed, the free end side of the movable plate protrudes outside the spatula.
In the vicinity of the portion where the movable plate is pivotally supported, there is a locking portion for restricting the return of the bent movable plate, so that the movable plate protrudes from the spatula and is locked by the locking portion. The position can be maintained.
Since the gripping part is heavier than the application part, when the spatula is placed on a desk or the like with the protruding movable plate on the bottom, the spatula application part is inclined upwards with the free end of the movable plate as a fulcrum A state is formed (see FIG. 4).
Therefore, when the spatula is used or temporarily placed, the applied viscous material does not adhere to the hand or the desk.

The shape of the movable plate is not particularly limited as long as the movable plate that is pivotally supported can be bent smoothly and can be supported when the spatula is placed.
The movable plate may be protruded only to one surface side of the spatula, or may be protruded to both surfaces.
The movable plate bent and locked to the locking portion can be easily released from the locked state by being pushed from the opposite side.

The second technical means is that the movable plate is pivotally supported on the application part side or the grip part side of the through-hole. Therefore, in the former, the free end side of the movable plate faces the grip part, and in the latter, the free end side is It goes to the application part side. Although the usage of the fingertips is slightly different, both have the advantage of being able to stabilize the spatula support.

In the third technical means, since the thickness of the grip portion on the central portion side is configured to be larger than the other portions, the spatula is temporarily placed on the desk without projecting the movable plate. However, the gap between the coating part and the desk can be increased by the height of the wall thickness on the center side. Therefore, it is possible to separate the viscous material remaining on the application part from the desk.
Moreover, since the spatula is lifted at that height, it becomes easy to pick the temporarily placed spatula with the fingertip.

In the fourth technical means, the thickness of the left and right side edge portions of the grip portion (the lower edge portion and the upper edge portion in FIG. 1 have a corresponding positional relationship) is configured to be larger than the other portions. Therefore, also in this case, when the spatula is temporarily placed on the desk, the gap between the coating section and the desk can be increased by the thickness of the wall on the center side (see FIG. 3).
In addition, since the outer edge of the gripping part becomes thicker and the outer surface becomes a wide flat surface, the temporary spatula can be easily picked with the fingertips, and when the flat surface of the side edge of the gripping part is brought into contact with the desk, It is also possible to temporarily place in an upright state (see FIG. 1). If the spatula is temporarily placed in an upright state, there is an advantage that the next coating operation can be performed smoothly.

In the fifth technical means, since a plurality of application surfaces having different application widths are formed in the application part, there is an advantage that an application operation corresponding to the application width can be performed.
The application surface can be formed in a triangular shape on the tip side of the spatula, two inclined edges can be used as the application surface, and a small application surface can be additionally formed by slightly cutting off the tip.

The spatula can be temporarily placed so that the sticky material remaining on the application part does not adhere to the hand or desk during the application work of viscous materials such as adhesives. There are advantages.
Since the movable plate can be protruded only at the time of application work, it can be packaged as a single spatula when packaging a viscous material, and there is also an advantage that the conventional packaging form can be maintained.

The application spatula 1 is made of plastic and has a length of about 75 mm, a width of about 17 mm, and a thickness of about 2 mm. The left and right side edge portions 3, 3 of the grip portion 2 are formed with a thickness of about 5 mm. The application part 5 is formed with a long inclined edge on the left side (the lower side in FIG. 1) of the tip part to form a wide application surface 6, and the right side (the upper side in FIG. 1) with a short inclination. A narrow application surface 7 is formed, and a triangular tip is cut vertically to form a dotted surface 8.

In this embodiment, a hexagonal through hole 10 is formed between the grip portion 2 and the application portion 5, and a substantially trapezoidal plate body 11 as a movable plate is positioned therein.
As shown in FIGS. 2 (a) and 2 (b), in this embodiment, the plate body 11 is connected to the distal end side (applying portion side) of the through hole 10 through the thin connecting pieces 12 and 12 arranged on the left and right. The tongue piece 13 is projected between them, and the other end side of the plate 11 is a free end (see a). Therefore, the free end is protruded to the outer side of the spatula 1 by pushing the plate body 11 with a finger (see b).

Locking portions 14, 14 project from the peripheral wall of the through hole 10 on the inner side of the attachment portions of the connecting pieces 12, 12. The bent state of the plate 11 is maintained.
In this embodiment, the through-hole 10, the connecting pieces 12, 12 and the plate body 11 are integrally formed. However, the through-hole 10, the connecting pieces 12, 12 and the plate body 11 may be appropriately divided and formed separately.

FIG. 3 shows the state of the spatula 1 with the spatula surface placed on the desk 15 as it is. In this state, a gap is formed between the desk 15 and the spatula application surface 2 with the thickness of the end portion.
Further, when the spatula 1 is placed on the desk 15 with the plate 11 protruding, the gripping portion 2 is heavier than the application portion 5 because the side edge portion is formed thick. As described above, the spatula 1 is temporarily placed in a state where the base end edge of the grip portion 2 is brought into contact with the desk 15 and the application portion 5 is directed obliquely upward.

FIG. 5 shows a case where the plate body 11 pivotally supported on the grip portion side is bent. When the spatula 1 is placed on the desk 15, the plate body 11 is positioned on the holding part 2 side and supports the spatula 1, so that even if the protruding length of the plate body 11 is shortened, the space between the coating unit 5 and the desk 15 is reduced. The gap can be formed large.
