Embodiment Construction

[0040] based on Figure 1 to Figure 7 Embodiments of the present invention will be described. figure 1 It is a schematic front view showing the overall structure of the package opening knife 1 according to the present embodiment, figure 2 is its top view. The package opening knife 1 in this embodiment will be described as an example of a disposal type (disposable type that is discarded without replacing the blade body) used in a manufacturing process in the food field. This package opening knife 1 is mainly composed of a resin main body 3 and a metal blade 5 .

[0041] (Structure of the main body part 3 and the guide part 9)

[0042] The main body 3 is formed of a resin material, which can be appropriately selected from, for example, PP (polypropylene), ABS, elastomer, polycarbonate, etc., and mixed with a metal filler. The reason for mixing metal fillers is to allow detection by metal detectors in order to avoid unwanted residues in the manufacturing process in the food ...

Abstract

Provided is a technology effective at further improving operability in a package opening operation. A package opening knife (1) is characterized in that the package opening knife (1) has a body part (3); a blade part (5); a gripping part (7) that extends in an elongated shape in a prescribed first direction (HD); and a guide part (9) provided with a guide surface that slides in a surface direction of the package in a state of contacting the package to guide movement of the blade part, and when a surface direction of the guide surface is defined as a second direction (GD), the first direction (HD) and the second direction (GD) become substantially parallel to each other.

Description

technical field [0001] The present invention relates to a technique for improving the operability of a package unsealing knife used for unsealing a package in particular. Background technique [0002] As an example of a cutting tool used in the food field, for example, a cutting knife disclosed in JP 2017-46962 A (Patent Document 1) is known. In order to avoid undesired residues in the product, there is disclosed a method of ensuring smooth operation characteristics of the metal parts while avoiding lubricant intervening between the metal parts while being made of detectable metal. [0003] However, it goes without saying that in the above-mentioned food field, in various fields, operations such as cutting and unsealing a package containing a predetermined content are often performed, but in this operation, there is a difference between cutting the package. Care should be taken to avoid accidentally damaging the contents. In this regard, the above-mentioned known cutting b...
