  TECHNICAL FIELD The present invention relates to a cream squeezing device, and more particularly to a device for squeezing whipped cream (whipped cream), butter cream, custard cream, etc. used in pastries such as cakes and cream puffs.

  FIG. 3 shows an example of a conventional cream squeezing method that uses a whipped cream or butter cream to finish a pastry decoration such as a cake or pastry. The illustrated squeeze bag 40 is a conical bag made of, for example, cloth, paper, or synthetic resin such as polyethylene, and its bottom surface is opened to form a circular inlet 41a, and its tip is cut to a predetermined size. Thus, a base hole 41b is provided. A base nozzle 35 is attached to the base hole 41b from the inside of the base bag 40, and the cream C is packed into the base bag 40 from the input port 41a while preventing leakage from the base nozzle 35. By applying pressure to the squeezing bag 40 while closing the inlet 41a, the stuffed cream C is squeezed from the tip of the base nozzle 35 onto the confectionery, and the base nozzle 35 is moved along with the squeeze bag 40 while the cream C is desired on the confectionery Draw a pattern and letters to finish the decoration. The squeezing bag 40 and the base nozzle 35 in the illustrated example are used not only for finishing the decoration, but also for squeezing custard cream or the like inside the skin of the cream puff.

  As shown in FIG. 4, a conventional mouthpiece nozzle 35 for cream squeezing has a squeezing hole of a petal shape, a round mouth shape, a saw blade shape, a Mont Blanc shape or the like at the tip of a cylindrical peripheral wall of a cone shape or a truncated cone shape. 36 is formed. As shown in the figure, the cream C is squeezed into stripes with different thicknesses and cross-sectional shapes by properly using a plurality of nozzles 35a to 35d having different shapes of the squeezing holes 36a to 36d, and various decorations are finished with the stripe cream. be able to. However, in the method of FIG. 3, since the nozzle nozzle 35 cannot be replaced while the cream bag 40 is filled with the cream C, it takes time to properly use the nozzle nozzle 35.

  On the other hand, as shown in FIGS. 5A to 5C, Patent Document 1 discloses a taber-shaped holder cylinder 31 having a male screw portion 33 formed on the outer peripheral surface together with a nozzle nozzle 35, and its male A cream squeezing tool 30 is disclosed that uses a nut cylinder 37 in which a female thread portion 38 to be screwed to the thread portion 33 is formed on the inner peripheral surface. As shown in FIG. 5A, first, a tapered outer peripheral surface 32 on the base end side (large diameter side) of the male threaded portion 33 of the holder cylinder 31 is attached to the cap hole 41b of the squeeze bag 40, and the holder cylinder 31 The male threaded portion 33 and a tapered outer peripheral surface 34 on the tip end side (small diameter side) are projected outward from the base hole 41. Next, after fitting the bottom of the conical surface of the base nozzle 35 into the protruding tapered outer peripheral surface 34, the nut cylinder 37 is fitted from the tip of the base nozzle 35, and the female screw part 38 is inserted into the male part of the nut cylinder 37. The base nozzle 35 is fastened to the holder cylindrical body 31 by being screwed onto the threaded portion 33 and pressing the outer peripheral surface of the base nozzle 35 with the inner peripheral surface 37 a of the nut cylindrical body 37. FIG. 4B shows a state in which the nozzle nozzle 35 is fixed to the holder cylinder 31, and FIG. 4C shows a sectional view thereof. The cream squeezing tool 30 in the illustrated example is configured such that the base nozzle 35 and the holder cylindrical body 31 are detachable by the nut cylinder 37, so that the base nozzle 35 can be easily placed with the cream C in the squeeze bag 40. Can be exchanged.

  Patent Document 1 also proposes a nozzle nozzle 39 with a nut in which a nozzle nozzle and a nut cylinder are integrated as shown in FIG. The nozzle nozzle 39 with a nut shown in the figure is made of, for example, a synthetic resin, and a nut portion 39a is formed integrally with a base end portion of a tapered cylindrical nozzle nozzle, and a female screw portion 39b is formed on an inner peripheral surface of the nut portion 39a. Formed. Since the cap nozzle 39 with nut is also configured to be detachable from the holder cylinder 31, the cap nozzle 39 with nut can be easily replaced while the cream C is packed in the air bag 40.

Japanese Patent Laid-Open No. 9-094067 JP-A-11-147549 Japanese Patent Laid-Open No. 7-327606 The Japan Society for Technology of Plasticity "Press Drawing-Process Design and Die Design-" Corona, first edition, 3rd edition, published on October 10, 2003

  However, the cream squeezing tool 30 in FIG. 5 has a problem that it cannot cope with the die nozzle 35 having a different diameter. The conventional nozzle 35 is required to have a brush-like shape from the viewpoint of workability in drawing patterns and characters with the squeezed cream C. For example, a straight line of a fan-shaped thin metal plate 51 as shown in FIG. The sides 51a and 51b are welded to form a cone shape or a truncated cone shape. For this reason, a conical shape having a different bottom diameter depending on the size of the squeezing hole 36 is adopted. For example, when the squeezing holes 36a and 36b are relatively small as shown in FIGS. When the squeezing holes 36c and 36d are relatively large as shown in FIGS. 3C and 3D, a conical shape having a large bottom diameter is formed. When the cream squeezing tool 30 shown in FIG. 5 is replaced with a nozzle nozzle 35 having a different diameter, it is necessary to replace the holder cylinder 31 into which the nozzle nozzle 35 is fitted.

  In the cream squeezing tool 30 of FIG. 5, it is effective to unify the diameters of as many nozzles 35 as possible in order to save the trouble of replacing the holder cylinder 31. However, the nozzle 35 that is processed by welding is often made of brass (brass), which has excellent workability, and is treated with rust prevention by plating, but the plating peels off during use and toxic patina is generated. Therefore, there is a problem that the usable period (life) is relatively short. Unifying the small nozzle nozzle 35 (for example, see FIG. 4 (B)) having a short life to a large diameter (for example, see FIG. 4 (D)) is not economical and practical because the material cost and processing cost increase. As shown in FIG. 5 (D), it is conceivable that the mouthpiece nozzle 35 is made of synthetic resin and the diameter is unified. However, the mouthpiece nozzle 35 made of synthetic resin is easily deformed when sterilized with hot water, and a clear cream squeezed shape is obtained. There are difficult drawbacks. In order to unify the diameter of the nozzle 35, it is necessary to develop a metal nozzle that is easy to process and has a long life.

  Therefore, an object of the present invention is to provide a cream squeezing device using a metal base that is easy to process and has a long life.

Referring to the embodiment of FIG. 1, the cream squeezing device according to the present invention has tapered cylindrical peripheral walls 6a and 6b (hereinafter, when it is not necessary to distinguish between the cylindrical peripheral walls 6a and 6b, the cylindrical peripheral walls are combined together). 6) and a hollow holder 2 provided with a nut holding portion 3 on the outer peripheral surface separated from the top wall 7 of the tip, and a metal sheet drawn molded body having a flange 12 that can be in close contact with the tip top wall 7 of the holder 2. 11 has a base 10 having a squeezing hole 15 in the convex portion 14, and a tapered thin peripheral wall 25 fitted to the outer peripheral surface from the tip top wall 7 of the holder 2 to the nut holding portion 3, and the thin peripheral wall 25 is attached to the holder 2 is provided with a holding nut 20 that holds the flange 12 of the base 10 in close contact with the tip top wall 7 of the holder 2 while being fitted to the base 2. For example, a reduced diameter portion 26 (see FIG. 1C) having a diameter larger than the convex portion of the base 10 and smaller than the flange 12 is provided at the tip of the shaft center hole 21 of the holding nut 20. The flange 12 is brought into close contact with the top end wall 7 of the holder 2.

Preferably, the base 10 is made of a steel sheet, a stainless steel sheet or an aluminum sheet, and has a cylindrical shape, a truncated cone shape or a hemispherical shape drawn with the same diameter d as that of the tip end 8 of the holder 2 as shown in FIG. A drawn molded body 11 with a flange 12 having a convex portion 14 is provided. It is desirable that the convex portion 14 of the base 10 has a height h (see FIG. 2) that can be molded in one drawing step. A tapered tip shape can be ensured by the total (L + h) of the distance L from the nut holding portion 3 of the holder 2 to the tip top wall 7 and the height h of the base 10.

The cream squeezing device of the present invention uses a base 10 in which a squeezing hole 15 is formed in a convex portion 14 of a drawn sheet 11 with a flange 12 made of a thin metal plate, and a tip top wall 7 of a hollow holder 2 having a tapered cylindrical peripheral wall 6. the nut holding portion 3 provided on the outer peripheral surface spaced from the distal end the top wall 7 of Rutotomoni hollow holder 2 are brought into close contact with the flange 12 of the base 10, fitted on an outer peripheral surface extending from the front end the top wall 7 of the holder 2 to the nut holding portion 3 Since the base 10 is held in close contact with the tip top wall 7 of the holder 2 by the holding nut 20 having the tapered thin wall 25 , the following remarkable effects are obtained.

(A) By making the die into a drawn body, it is easier to process than a nozzle nozzle that requires a conventional welding operation, and the processing cost of the die can be kept low.
(B) Since welding is not required for forming the die, the material of the die can be made of a steel sheet, stainless steel sheet or aluminum sheet that is not easily rusted, and can be used in comparison with conventional brass nozzle nozzles ( It can be a base having a long life).
(C) Depending on the size and shape of the squeezing hole of the base, it is possible to make the shape of the convex portion cylindrical, frustum-shaped, hemispherical or the like while maintaining the shape of the flange.
(D) Even if the height h of the convex part of the base is small , the tip of the squeezing tool is obtained by the total (h + H) by increasing the distance H between the nut holding part of the holder and the top wall of the tip. In addition, it is possible to secure a pen tip shape long enough to draw a pattern or characters with cream.
(E) A plurality of bases having different squeezing hole sizes and shapes can be easily used, and a drawn molded body without a squeezing hole can be used as a lid base, which can be used for protecting and storing cream. .

  FIG. 1 shows an embodiment of a cream squeezing device 1 according to the present invention. The cream squeezing device 1 in the illustrated example has a tapered tube shape having a base 10 provided with a squeezing hole 15 in a convex portion 14 of a drawn body 11 with a flange 12 and a tip top wall 7 that can be in close contact with the flange 12 of the base 10. And a holding nut 20 that holds the flange 12 of the base 10 in close contact with the tip top wall 7 of the holder 2 while being fitted to the hollow holder 2. The base 10 is made of a thin metal plate that can be drawn, but the holder 2 and the holding nut 20 can be made of metal or synthetic resin.

  A nut holding portion 3 is provided at a predetermined site on the outer peripheral surface of the hollow holder 2, and a fitting portion 24 is provided in the axial hole 21 of the holding nut 10 so as to be aligned and coupled with the nut holding portion 3 of the holder 2. In the illustrated example, the holding part 3 of the holder 2 and the fitting part 24 of the nut 20 are respectively threaded parts, and the holder 2 and the nut 3 are screwed together to be coupled. For example, the nut 3 or the holder 2 is made of a magnetic material. The holding unit 3 or the fitting unit 24 may be used as magnets, and both may be coupled by magnetic force. Further, the nut 20 in the illustrated example is provided with a reduced diameter portion 26 having a diameter larger than the convex portion 14 of the base 10 and smaller than the flange 12 at the distal end opening 22 of the shaft center hole 21. By abutting against the top wall 7, the holding portion 3 of the holder 2 and the fitting portion 24 of the nut 20 are aligned.

  FIG. 2 shows an embodiment of a die 10 using a drawn body 11 with a flange 12 used in the present invention. Any of the illustrated caps 10a to 10d can be formed relatively easily using a conventional drawing technique. For example, a thin metal plate (blank) having a predetermined shape and a predetermined size is positioned and sandwiched between a die and a wrinkle suppression plate, and a cylindrical punch is pushed into the die so as not to cause wrinkles. 11 is formed, and a squeeze hole 15 is formed on the top surface of the formed convex portion 14 with a drill or the like to form the base 10. Alternatively, after the squeezing hole 15 is previously formed in the metal thin plate, the squeezing hole 15 is formed into the convex portion 14 so as to form the die 10. The shape and size (blank diameter) of the metal thin plate can be calculated in advance from the diameter d of the convex portion 14 of the drawn molded body 11, the outer diameter D of the flange 12, the height h of drawing, and the like (Non-Patent Document 1). See pages 44-48). Preferably, the base 10 is made of a steel sheet, a stainless steel sheet, or an aluminum sheet that does not rust and does not require plating.

  The shape of the convex portion 14 of the base 10 is, for example, a cylindrical shape in FIG. 2A, a truncated cone shape in FIG. 2B, or a hemispherical shape in FIG. It can be selected as appropriate. Since the cylindrical base 10a has a comparatively large top surface of the convex portion 14, a squeezing hole 15 similar to the conventional comparatively large diameter base nozzle 35d (see FIG. 4D) can be provided. The truncated cone-shaped base 10b and the hemispherical base 10d are suitable for the case where a relatively small squeezing hole 15 (see FIG. 4B) is provided. Furthermore, the shape of the convex portion 14 can be appropriately deformed according to the shape and size of the squeezing hole 15. FIG. 2 (C) shows a base 10c in which the convex portion 14 is formed in an elliptical cone shape, and this base 10c is suitable for the case where a linear squeezing hole 15 (see FIG. 4 (C)) such as a saw blade shape is provided. ing.

  Regardless of the shape of the convex portion 14, the base 10 using the drawn molded body 11 matches the diameter d of the convex portion 14 with the diameter of the tip end 8 of the hollow holder 2, and sets the outer diameter D of the flange 12 to that of the holder 2. The outer diameter of the tip top wall 7 can be matched. In this way, the flanges 12 of the bases 10a, 10b, 10c, and 10d provided with the squeezing holes 15 of various sizes and shapes as shown in FIG. . By forming the flange 12 into a shape that can be brought into close contact with the top end wall 7 of the holder 2, when the base 10 is held in close contact with the holder 2 as shown in FIG. A cream passage communicating smoothly with the ten convex portions 14 can be formed.

  The drawing height h of the convex portion 14 of the base 10 can be increased by repeating drawing (redrawing), but it is desirable to make it as high as possible in one drawing process. For example, when the die 10 having the frustoconical convex portion 14 shown in FIG. 2B is formed, if the drawing height h is 0.4 to 0.55 times the diameter d of the convex portion 14, approximately one drawing step. Although it can be molded, it is said that it cannot be molded in a single drawing process when the drawing height h is 0.8 to 1.5 times the diameter d or more (see page 43 of Non-Patent Document 1). If the diameter d of the convex portion 14 is about 10 to 30 mm, the drawing height that can be formed at one time is about 5.5 to 16.5 mm. That is, there is a limit to the drawing height h of the die 10 that can be formed in one drawing process.

  When the drawing height h of the convex portion 14 of the base 10 is small, the nut holding portion 3 of the holder 2 is provided on the outer peripheral surface separated from the top wall 7 as shown in the example, and the holding portion 3 of the holder 2 It is desirable to provide a tapered peripheral wall 6b with a distance L between the tip top wall 7 and the tip top wall 7. In this case, the fitting portion 24 of the holding nut 20 is provided on the base end side (large diameter side) of the shaft center hole 21, and the outer peripheral surface of the tapered peripheral wall 6 b of the holder 2 on the tip end side (small diameter side) of the shaft center hole 21. A tapered thin peripheral wall 25 that fits (circumscribes) is provided. By holding the base 10 in close contact with the tip of the tapered peripheral wall 6 b of the holder 2, a sufficient amount of the distance L between the tapered peripheral walls 6 b and the drawing height h of the base 10 (L + h) is sufficient at the tip of the holder 2. It is possible to ensure a tapered shape like a brush tip of length.

When the cream squeezing device 1 of the illustrated example is attached to the squeezing bag 40 and the cream is squeezed, first, as in the case of FIG. 2), the nut holding portion 3 of the holder 2 and the tapered peripheral wall 6b on the tip end side thereof are projected from the base hole 41 to the outside. The proximal end side peripheral wall 6a of the holder 2 in the illustrated example is provided with an annular stepped portion so that it is difficult to slip, and the annular stepped portion can be securely fixed to the cap hole 41b of the air bag 40. Next, the flange 12 of the base 10 having a desired squeezing hole 15 is aligned with the tip top wall 7 of the tapered peripheral wall 6b on the tip side protruding from the base hole 41b, and the fitting portion 24 of the holding nut 10 is fitted to the nut. The flange 12 of the base 10 is held in close contact with the tip top wall 7 of the holder 2 by being fitted to the holder 2 until it is coupled to the holding portion 3. FIG. 1D shows a cross-sectional view of the base 10 held in close contact with the holder 2. In this state, by filling cream C into the squeezing bag 40 and press-fitting cream C from the cream intake 9 of the holder 2, the cross section corresponding to the squeezing hole 15 of the base 10 as in the case of FIGS. 3 and 5. Cream C can be squeezed into a streak shape by shape and thickness.

  The cream squeezing device 1 of the present invention can change the size and shape of the squeezing hole 15 of the convex portion 14 without changing the diameter (flange diameter) of the base 10, and the squeezing hole 15 as compared with the conventional cream squeezing tool. It is easy to replace the base 10 according to the proper use. Further, by increasing the distance L from the nut holding portion 3 of the holder 2 to the tip top wall 7, even when the height h of the convex portion 14 of the base 10 is small, it is long enough to draw a pattern or characters. It is possible to ensure a tapered shape like a brush tip. Furthermore, since the base 10 is made of a drawn body, welding work is not required, so that the processing cost can be kept low, and the base 10 can be made of a stainless steel sheet that is not easily rusted. The period (lifetime) can be extended.

  Thus, provision of “a cream squeezing device using a metal base that is easy to process and has a long life”, which is an object of the present invention, can be achieved.

  FIG. 2 (E) shows an embodiment of a lid base 17 made of a drawn molded body 11 with a flange 12 without a squeezing hole 15. The lid base 17 can be formed by the same drawing process as the base 10. In the conventional squeezing method shown in FIG. 3 or FIG. 5, there is no appropriate method for covering the die nozzle 35 when the cream C packed in the squeeze bag 40 remains, for example, the squeezing hole 36 of the die nozzle 35 is provided. This is dealt with by a method such as temporarily storing the squeeze bag 40 in a refrigerator or the like (see Patent Document 2). However, there is a concern about hygiene such that the cream C leaks from the nozzle nozzle 35, and conversely dust is mixed into the cream C. The cream squeezing device 1 of the present invention uses a lid base 17 as shown in FIG. 2 (E) instead of the base 10 having the squeezing hole 15 formed in the convex portion 14 as shown in FIGS. Thus, the cream C remaining in the squeeze bag 40 can be effectively used for storage and protection. It is also possible to cover the cream C by overlapping the cap base 17 on the base 10 having the squeezing hole 15.

The lid base 17 in the illustrated example can also be used to prevent leakage when the squeezed bag 40 is filled with the cream C. That is, when attaching the holder 2 to the base hole 41b of the air bag 40, the front end 8 of the holder 2 is closed with the lid base 17, and after packing the cream C into the air bag 40, the front end of the holder 2 is closed. The cream C is squeezed out by replacing the lid base 17 of 8 with the base 10 having a desired squeezing hole 15 formed therein. Further, when the squeezed bag 40 filled with the cream C is distributed in the market, it can be expected that the cream squeezing device 1 of the present invention provided with the lid base 17 is used.
