[Figure 2] (a) is a partially enlarged view of Fig. 1(a), and (b) is a cross-sectional view taken along line b-b of (a). [Figure 3] As an example of the extraction tool according to the present invention, a secondary molded body (finished product) of a spatula is shown, wherein (a) is a plan view of the secondary molded body, (b) is a side view of the secondary molded body, and (c) is a front view of the secondary molded body. [Figure 4]It is a partial half cross-sectional view showing a container with a spatula fixed as an application example of the ejector. MODE FOR CARRYING OUT THE INVENTION

[0016] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following, resin molding The removed tool will be described by taking a spatula as an example, Removal tool it is not limited to a spatula, and other For example, a fork or other members may be used. The spatula is an ejector for scooping out the content accommodated in a container, for example, as will be described later, and is detachably fixed as an accessory to a fixing portion inside or outside the container before use.

[0017] As shown in FIGS. 1 to 3, Removal tool a spatula 1 shown as one embodiment of the present invention is provided with a wide scoop portion 2 on one end side in the longitudinal direction, and a handle portion 3 that is gradually narrowed on the other end side, is formed in a substantially ship shape in plan view as a whole, and is formed to include a primary molded body (intermediate body) 1A formed using a synthetic resin material and a secondary molded body (finished product) 1B that covers the surface of the primary molded body 1A.

[0018] First, the primary molded body (intermediate body) 1A will be described. As shown in FIG. 1(b) and FIG. 2(b), a circular recess 4 is formed at the central position on the surface 1a side of the primary molded body 1A, and a part of the lower surface 11 side of an insert member 10 made of, for example, a circular iron metal plate (iron plate) is embedded in the recess 4. In FIGS. 1 to 4, the insert member 10 is shown with hatching.

[0019] As shown in an enlarged view in Figure 2(a), multiple claw-shaped locking portions 5 (three in this embodiment, spaced 120 degrees apart in the circumferential direction) are formed on the surface 1a side, protruding from the edge of the recessed portion 4 toward the center. Each locking portion 5 is integrally formed with a columnar portion 5a protruding upward from the surface 1a and a locking piece 5b extending from the upper end of the columnar portion 5a toward the center of the recessed portion 4 (radially inward).

[0020] As shown in Figure 2(b), the insert member 10 is firmly fixed in place by its lower surface 11 being held down in the thickness direction by the bottom wall 4a of the recessed portion 4 which constitutes the mounting surface 6, and by its upper surface 12 being held down by the locking pieces 5b at the tip of each locking portion 5. In the case of a configuration without a recessed portion 4, the surface 1a of the primary molded body 1A may be used as the mounting surface 6 instead of the bottom wall 4a.

[0021] At the same time, the insert member 10 is firmly fixed by the fact that its outer peripheral surface 13 is pressed down from the radially outer side to the inner side by a plurality of columnar portions 5a. In this way, the insert member 10 can be held in place in both the thickness direction and the radial direction, so the insert member 10 does not easily detach from the primary molded body 1A.

[0022] Next, we will explain the second molded product (finished product). The spatula 1 shown as the second molded body in Figure 3 is formed by embedding a primary molded body with the insert member 10 fixed inside a secondary molded body 1B, and the insert member 10 is completely covered by the secondary molded body 1B provided on the outside. Removal tool This is the completed form. Removal tool By configuring the spatula 1 in this way, the insert member 10 can be hidden inside the synthetic resin that constitutes the secondary molded body 1B, thus providing a protected state where the insert member 10 is not directly exposed to the outside.

[0023] Next, the above Removal tool This section explains examples of its use. Figure 4 shows Removal toolAs an example of use, this is a partial cross-sectional view of the container showing an example of using spatula 1. As shown in Figure 4, the container 20 is a double-walled container comprising an outer container 22 into which an inner container 21 is fitted, and an outer lid 24 into which an inner lid 23 is fitted. The female threads 23a formed on the inner side surface of the inner lid 23 can be detachably screwed onto the male threads 21a formed on the upper outer surface of the inner container 21. The container 20 can be opened and closed by holding the outer container 22 with one hand and rotating the outer lid 24 in the circumferential direction with the other hand. A packing 25 is provided between the upper end of the inner container 21 and the inner lid 23.

[0024] A gap 26 is formed where the top wall 23A of the inner lid 23 and the top surface 24A of the outer lid 24 face each other in the height direction, and a magnet M is fixed in the center of this gap 26. Therefore, when the spatula 1 described in the above embodiment is placed on the top surface 24A of the outer container 22, the insert member 10 made of an iron plate provided inside the spatula 1 is magnetically attracted to the magnet M, making it possible to fix the spatula 1 on the top surface 24A of the outer lid 24. In other words, in this example of use, the top surface 24A of the outer lid 24 functions as a fixing part for fixing the spatula 1.

[0025] Thus, in this invention, the movement of the spatula 1 can be restricted, thereby suppressing the generation of abnormal noises when carrying the container. Furthermore, since the spatula 1 is fixed to a fixing part provided on the outside of the container 20, namely on the top surface 24A of the outer lid 24, solely by magnetic attraction, it can be easily removed from the fixing part by, for example, pinching the handle 3 of the spatula 1. Then, after rotating and removing the outer lid 24 of the container 20 together with the inner lid 23, the contents contained in the inner container 21 can be removed using the spatula 1.

[0026] Next, we will explain the manufacturing method of the spatula 1 described above.

[0027] (1) First molding process First, an insert member 10 is placed in a predetermined position within a first molding die (not shown), and a primary molded body 1A is formed by filling it with molten resin. At this time, a recessed portion 4 and a plurality of locking portions 5 are simultaneously formed around the primary molded body 1A. A preferred method for placing the insert member 10 in a predetermined position within the first molding die is to use a magnet provided within the first molding die. Alternatively, the insert member 10 can also be placed in a predetermined position within the first molding die by air attraction.

[0028] (2)Second forming process Next, the primary molded body 1A formed in the first molding process is placed as an insert material in a predetermined position in a second molding die (not shown), and molten resin is filled to form the completed spatula 1, which is the secondary molded body 1B. In this process, the primary molded body 1A having the insert member 10 is embedded in the molten resin, and after curing, a spatula 1 can be formed consisting of a secondary molded body 1B in which the insert member 10 is completely covered by synthetic resin.

[0029] The configuration of the present invention and its effects have been described above in accordance with the examples, but the embodiments of the present invention are not limited to the above examples.

[0030] For example, in the above embodiment, an iron metal plate was shown and described as the insert member 10, but other materials such as magnets may also be used.

[0031] Furthermore, although the explanation described a configuration in which the insert member 10 is made of iron metal plate and a magnet M is provided on the container side, it is also possible to use a configuration in which the insert member 10 is a magnet and an iron metal plate is provided on the container side, or a configuration in which both the insert member 10 and the container side are magnets.

[0032] Furthermore, although the above embodiment described a case in which three locking parts 5 are provided, the number of locking parts 5 is not limited to three.

[0033] Furthermore, although the above example of use described a configuration in which the spatula 1 is fixed to the outside of the container 20 (the top surface 24A of the outer lid 24), it is also possible to use the gap 26 between the outer lid 24 and the inner lid 23 as the fixing point and place the spatula 1 within this gap. In this case, it is possible to implement this by making the inner lid 23 detachable from the outer lid 24 and embedding the magnet M inside the inner lid 23 or the outer lid 24. [Industrial applicability]

[0034] The present invention Removal tool Furthermore, it is possible to expand the applications of the manufacturing method in a wider range of fields. [Explanation of symbols]
