Abstract

The utility model discloses a cutter for opening and unsealing a bag, which comprises a shell and a blade, wherein the shell comprises a main body and an auxiliary body, the upper edge of the main body and the lower edge of the auxiliary body are arranged at intervals which are straight and parallel to each other, the intervals form a bag opening groove for the bag body to enter, the blade is embedded into the main body and the auxiliary body, and the blade edge of the blade is arranged in the bag opening groove and is arranged towards the inlet direction of the bag opening groove. According to the utility model, through the linear parallel bag opening groove structure formed by the main body and the auxiliary body, a physical guide channel is formed during operation, so that the packaging bag is ensured to enter the cutter action area along a preset track. The cutting action is naturally matched with the travelling direction of the bag body due to the arrangement of the cutting edge towards the inlet direction, so that the track deviation caused by material rebound during cutting by the traditional cutter is effectively avoided, and the remarkable improvement of the flatness of the cut is realized. The whole operation process of the bag opening tool is simple and easy to understand, and a user can finish the cutting operation of the bag only by holding the tool with one hand. Whether the bag is a conventional HDPE bag or a thicker aluminum foil bag, the bag can be easily opened through corresponding operation steps, other complex tools are not needed, the bag opening time is greatly saved, and the working efficiency is improved.

Description

Cutter for opening bag Technical Field The utility model belongs to the technical field of auxiliary packaging tools, and particularly relates to a cutter for opening bags, which is suitable for various quick opening scenes of products packaged by HDPE bags or aluminum foil bags, such as foods, medical supplies, daily necessities and the like. Background High Density Polyethylene (HDPE) bags and aluminum foil composite bags have become the mainstay of choice for packaging food, medical supplies and precision products due to their excellent sealability, moisture resistance and barrier properties. However, the physical characteristics of the HDPE bags are derived from the remarkable unsealing difficulty in actual use, the HDPE bags are tough and elastic in material, irregular cracks are easy to generate when the HDPE bags are torn by bare hands, particularly, when the HDPE bags are filled with liquid or powder, the contents are easy to spill, the operation deviation is often caused by rebound of the material when the HDPE bags are cut by a cutter, the aluminum foil bags are light and thin in texture, but the edges of the metal layers of the HDPE bags are sharp, the forced tearing is time-consuming and labor-consuming, the burr-shaped section is easy to form at the mouth of the HDPE bags, and the risk of scratching exists. Currently consumers generally rely on freehand tearing or traditional cutting tools to open bags, but both have obvious drawbacks. The method has the advantages that the damage to the package integrity is large due to bare-handed operation, uneven cuts and improper force application can cause structural package bursting, tools such as scissors are difficult to apply force stably due to the curved surface shape of the bag body, the cutting track is easy to deviate from the preset position, and the operation efficiency and the safety are difficult to guarantee especially in special environments such as medical emergency and outdoor scenes. Market research shows that the existing bag opening mode cannot meet the core requirements of users on accurate unsealing and safety and controllability, and development of a special unsealing cutter with functions of notch guiding, stable force application and safety protection is needed. Disclosure of utility model The utility model aims to solve the technical problems of overcoming the defects of the prior art, and providing a cutter for opening bags, which realizes the operation with taking and using, light weight and multi-scene adaptation by optimizing the blade structure, the portable design and the safety consideration. In order to achieve the above purpose, the technical scheme of the utility model is as follows: The utility model provides a cutter for opening bag unsealing, includes shell and blade, the shell includes main part and vice body, the upper edge of main part and the lower edge of vice body are sharp and interval setting that is parallel to each other, the interval forms the bag groove that opens that supplies the bag body to get into, the blade embedding in main part and the vice body, the cutting edge setting of blade is in open the inside in bag groove, and towards open the entry direction setting in bag groove. In a preferred embodiment, the cutting edge of the blade forms an acute angle with the edge of the pocket. In a preferred embodiment, the blade edge is angled from 20 ° to 60 ° from the pocket edge.
