Description

[Technical Field]

[0001] The present invention relates to a pet chew that can be reliably chewed by small pet animals such as dogs and that can effectively remove dental plaque, and to a method for producing the same. [Background technology]

[0002] Conventionally, pet chews have been proposed that are flat, rod-shaped, toothbrush-shaped, animal bone-shaped, or small shoe-shaped, or that combine roughly spherical, cylindrical, and stick shapes, as disclosed in, for example, Patent Document 1 (Utility Model Registration No. 3096655) and Patent Document 2 (Utility Model Registration No. 3147105).

[0003] However, due to the shape of a pet's teeth, only a portion of the teeth comes into contact with the gum. For example, Patent Document 3 (Utility Model Registration No. 3164297) proposes gum in which the main raw material is molded into spiral, mesh, and cylindrical shapes using an extrusion molding machine.

[Brief explanation of the drawings]

[0013] [Figure 1] 1 is a perspective view of a pet chew 1 according to one embodiment of the present invention. [Figure 2] 1 is a schematic view showing an end face (or a vertical cross section) of pet chew 1. FIG. [Figure 3] FIG. 1 is a perspective view of a pet chew 101 according to another embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0014] Hereinafter, preferred embodiments of the pet chew of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to these drawings. The drawings are intended to conceptually explain the present invention, and therefore, for ease of understanding, dimensions, ratios, or numbers may be exaggerated or simplified as necessary.

[0015] <Pet chew> Fig. 1 is a perspective view of a pet chew 1 according to one embodiment of the present invention. As shown in Fig. 1, the pet chew 1 is made of a mixture of at least cowhide, cellulose, and glycerin, as will be described later, and is long in shape. Therefore, it can be chewed firmly for a long time.

[0016] As can be seen from the end surface shown in Figure 1, when viewed in a cross section approximately perpendicular to the length direction, pet chew 1 is roughly cylindrical or stick-shaped, but in detail, its outer shape is approximately polygonal. This makes it easy to chew by fitting and fixing it to the teeth as a whole, allowing the pet to chew firmly for a long time. In Figure 1, the outer edge is a roughly dodecagonal star-shaped polygon, but it is not limited to this and may have various polygonal shapes.

[0017] The pet chew 1 has, from the inside to the outside, a soft chewing layer 2 and a hard shell layer 4 covering the chewing layer 2. Both the chewing layer 2 and the shell layer 4 are made of the above mixture, but the shell layer 4 is formed by heating the mixture, drying it, and solidifying it, and is harder than the chewing layer 2.

[0018] The chewing layer 2 has five circular openings 6 arranged at approximately equal intervals, and the openings 6 penetrate the pet chew 1 in the longitudinal direction. This allows plaque to be effectively removed and allows the pet to chew firmly. The number of openings 6 may be selected as appropriate within a range that does not impair the effects of the present invention, but from the perspective of maintaining quality such as dimensional accuracy resulting from the extrusion process, three to seven openings are preferred.

[0019] Here, the dimensions of the pet chew 1 will be described. The diameter (outer shape) D (see FIG. 2) of an imaginary circle C formed by connecting the vertices of the polygonal outer edge of the pet chew 1 is preferably 5 mm to 20 mm, but may be appropriately selected depending on the dimensions of the opening 6 and the size of the intended pet, as long as the effects of the present invention are not impaired. In particular, a diameter of 8 mm to 18 mm is preferable.

[0020] Furthermore, the height h of the vertex of the polygonal portion of the outer edge of the pet chew 1 may be selected appropriately within a range that does not impair the effects of the present invention, but from the viewpoint of maintaining quality such as dimensional accuracy resulting from the extrusion process and from the viewpoint of more reliably obtaining the effects of the present invention, it is preferable that it be 1 mm to 5 mm, preferably 1 mm to 3 mm.

[0021] The diameter d of the opening 6 may be selected appropriately within a range that does not impair the effects of the present invention, but from the viewpoint of maintaining quality such as dimensional accuracy resulting from the extrusion process and from the viewpoint of more reliably obtaining the effects of the present invention, it may be selected appropriately within a range of 1 mm to 5 mm, preferably 1 mm to 3 mm, depending on the diameter D of the pet chew 1 and the size of the target pet, etc.

[0022] The thickness of the shell layer 4 may be, for example, about 0.5 mm to 1 mm, but it does not have to be clearly separated from the chewing layer 2. For example, the degree (height) of solidification of the pet chew 1 may decrease gradually or in stages from the outside to the inside, thereby forming a hard shell layer 4 and a soft chewing layer 2. From the viewpoints of reliably exerting the plaque removal effect and ensuring sufficient strength, the ratio of the cross-sectional area of ​​the chewing layer 2 to the total opening area of ​​the openings 6 may be 5:1 to 15:1, and more preferably 8:1 to 10:1.

[0023] In this embodiment, the following shapes and dimensions are used. The polygonal shape of the outer edge of pet chew 1 is a dodecagon. Height of the vertex of the polygonal part: h 2mm Pet chew 1 diameter D 16mm Number of openings 6: 5 Diameter of opening 6 d 2mm Shell layer 4 thickness: 0.5mm Cross-sectional area of ​​chewing layer 2: total opening area of ​​opening 6 = 144:15.7

[0024] The pet chew 1 contains at least cowhide, cellulose (dietary fiber), and glycerin, and may contain rice flour, tapioca, wheat flour, cornstarch, soy flour, and the like as additional ingredients.

[0025] In particular, from the viewpoint of realizing the shape and dimensions of the pet chew 1 described above and reliably obtaining the effects of the present invention, it is preferable that the raw material mixture contains 40 to 50% by mass of cowhide, 20 to 30% by mass of cellulose, and 10 to 20% by mass of glycerin, when the total of all components is 100% by mass.

[0026] Furthermore, from the viewpoint of more reliably obtaining the effects of the present invention, it is preferable that the raw material mixture contains 42 to 45 mass% of cowhide, 20 to 25 mass% of cellulose, and 13 to 18 mass% of glycerin, when the total of all components is 100 mass%.

[0027] These three components contained in the raw material mixture are contained in approximately the same proportions in the final product after extrusion molding, drying and solidification.

[0028] <Pet chew manufacturing method> The pet chew 1 of this embodiment can be manufactured by (1) a mixing process in which at least cowhide, cellulose, and glycerin are mixed to obtain a raw material mixture, and (2) an extrusion process in which the raw material mixture is extruded using a nozzle corresponding to the cross-sectional shape of the pet chew.

[0029] The mixing conditions in the above mixing step (1), such as the mixing order, mixing method, mixing temperature, and mixing (stirring) time, may be appropriately selected within a range that does not impair the effects of the present invention. However, from the viewpoint of uniform dispersion, it is preferable to mix the cowhide, rice flour, cellulose, tapioca, and glycerin in this order, and the mixing (stirring) time is preferably about 3 to 5 minutes.

[0030] Furthermore, the various conditions of the heating temperature, heating time, and extrusion (discharge) speed in the extrusion step (2) may be appropriately selected within a range that does not impair the effects of the present invention. However, it is preferable that the heating temperature of the mold is 95 to 105°C and the time during which the raw material mixture passes through the mold (heating time) is 8 to 12 seconds so that the inner chewing layer 2 is soft and the outer shell layer 4 is hard.

[0031] After the mixing step (1) and the extrusion step (2), the pet chew 1 of the present embodiment can be manufactured by solidifying the mixture by drying, such as natural drying. The drying method may be, for example, air blowing or hot air drying.

[0032] The pet gum 1 of this embodiment is obtained through the above-described steps, but the present invention is not limited to these steps, and various design modifications are possible, and these design modifications are also included in the technical scope of the present invention.

[0033] For example, when the outer diameter is small (for example, about 10 mm) like pet chew 101 shown in FIG. 3, three openings 106 may be provided in chewing layer 102 inside outer hard shell layer 104.
