Description

Technical field

The utility model relates to kitchen utensils, in particular to specialized multifunctional tools for opening plastic metallized bags and extracting their contents, for example, for opening wet pet food bags.

State of the art

Packing portions of wet pet food is usually done in rectangular plastic metallized bags sealed at the top edge (also called pouches).

In the description of the patent EP 1769908 A1, IPC B29C 47/06, B32B 27/08, B32B 27/32, C08L 23/08, C08L 23/12, B65D 65/40, B65D 77/12, publ. 04/04/2007, it was rightly noted that a significant part of users are faced with the problem of opening such packages without using a tool (scissors, knives or similar devices) or because the film forming the package is too strong and requires considerable effort to complete the opening, even if a special cut is made on the end side of the package, or because the films forming opposite sides of the package are torn in directions other than desired, due to which part of the contents spill out in an uncontrolled way.

From the prior art, the design of special scissors for opening packages and extracting their contents, see US patent 3142074 A, IPC B65B 69/00, publ. 07/28/1964

The disadvantages of the design of special scissors are increased complexity, the presence of moving parts, increased risk of injury, limited functionality, significant dimensions and weight.

The closest analogue of the claimed utility model is the design of a multifunctional tool for opening packages and extracting their contents, known from US patent 4570339 A, IPC A47G 21/00, A47J 43/28, B26B 11/00, publ. February 18, 1986

The design of the closest analogue includes:

- a working part, in which a longitudinally oriented slot is formed, limited on three sides by the walls of the working part and open from the side of the peripheral end of the working part, and a recess in which a metal plate with a blade is installed, as well as

- rear grasping part (hereinafter referred to as simply the back part).

The working and rear parts of the tool, taken as the closest analogue, are made entirely by casting from a polymer material.

A metal plate with a blade is designed to safely cut the edge of the bag, a slot in the working part serves to expel the contents of the bag by pulling the bag through the slot, and the back part serves to hold the tool in hand.

The implementation of the multifunctional tool, made in accordance with US 4570339 A, can be viewed on the Internet, for example, at the following links:

https://shop.dinecompany.com/tangibles-pouchmate-plastic-food-bag-cutter/

The disadvantages of the design of the closest analogue are:

- inconvenience of use, due to the impossibility of performing a neat linear cut of the upper part of the bag;

- limited functionality, which consists in the impossibility of performing a neat linear cut of the upper part of the bag and the lack of means for mixing the contents of the bag;

- increased injury risk of the tool design, due to the casting of parts of the tool from a brittle polymer material that can break with the formation of sharp edges, for example, when the tool falls or physical forces are applied to it; in the event of a fall and destruction of the tool, it is possible to separate a traumatic metal plate with a blade;

- increased dimensions of the tool, due to the use of a polymer material and the implementation of a slot open from the side of the peripheral end of the working part;

- environmental pollution due to the use of polymer material for the manufacture of tools;

- high labor intensity and inconvenience of removing contaminants from the surfaces of the tool during washing, due to the complex geometry of the body, in particular, the presence of stiffeners.

Disclosure of the essence of the utility model

On FIG. 3 shows the moment of cutting off the top of the bag.

Positions on the images are indicated:

1 - tool; 2 - working part; 3 - back; 4 - slot; 5 - blade; 6 - scapula; 7 - hole in the working part for hanging the tool; 8 - hole in the back for hanging the tool.

Implementation of the utility model

The proposed utility model can be implemented as follows.

Tool 1 (see Fig. 1, 2) is made of a thin elongated metal plate.

In particular, a steel metal plate 1.2 mm thick was used to manufacture a prototype tool.

A reasonable choice of plate thickness lies in the range from 1 to 2 mm, which does not exclude the possibility of making a tool from a plate with a thickness of more than 2 mm.

The peripheral end of the working part 2 of the tool is made in the form of a blade 6, that is, a wide flat blade or a flat scoop of a spoon.

In the working part 2 of the tool 1, a slot 4 is made.

The slit can be made by laser or by the tool punching process.

The width of the slot 4 is chosen slightly greater than twice the value of the wall thickness of the bag.

In particular, for the manufacture of a prototype tool, a slot 2.5 mm wide and 110 mm long was made.

The length of the slot is selected based on the width of the bag, which must pass freely through the specified slot.

Blade 5 is made in the wall limiting the slot 4 from the side of the peripheral end of the working part 2 of the tool 1.

In particular, in the manufacture of a prototype tool, a blade was obtained with sharpening on both sides at an angle of 40 degrees along a radius of 11 mm.

A blade with a width of less than 2.5 mm, placed in a narrow slot, bounded on all sides by walls, is quite safe to use.

The outer surfaces of the tool do not have sharp cutting edges.

The choice of the dimensions of the working part of the tool is correlated with the dimensions of the bag.

For a specialist it is clear that the tool of the proposed design can be successfully used to open bags for sauces, pouches, doy-packs of various sizes, while it is necessary to adjust the length of the slot in accordance with the width of the package. For example, to open doy-packs, the slot length must be increased to 130 mm.

It is also possible to make the tool with two longitudinally oriented slots of different lengths. In this case, both slots can be made in the working part of the tool, placing them in a row, or the first slot of the first length can be made in the working part, while the second slot of the second length can be made in the rear part, while the blade of the second slot will need to be made in the wall, limiting the second slot from the side of the peripheral end of the back.

The dimensions of the rear (grasping) part and its contour can be changed by the manufacturer within a fairly wide range, in accordance with ergonomic requirements, design, etc.

Holes can be made in the working part 2 of the plate and/or the back part 3 of the tool for convenient hanging of the tool on a hook.

The back part 3 of the tool 1 can be provided with an overhead handle, consisting of two plates, which are located on both sides of the back of the tool.

The handle plates can be secured to the back, for example, with mounting holes made in the handle plates and at the back of the tool, and rivets.

The handle plate material can be wood, bamboo, non-ferrous metal, non-ferrous alloy (eg bronze, brass) or steel. The use of decorative overlays for the manufacture of the handle increases the attractiveness of the instrument.

In particular, the applicant first received and tested a prototype without a handle, then the tool was equipped with a handle made of wood.

The tool is used in the following way.

The upper part of a rectangular plastic metallized bag (pouch), for example, a bag of wet cat food (see Fig. 3), is inserted into slot 4.

Holding the bag below the slot 4 with one hand, move the back part 2 of the tool 1 with the other hand, while cutting off the upper part of the bag with the blade 5 with one movement.

Using the tool is equally convenient for left-handers and right-handers.

After cutting off the upper part of the bag and gaining access to the contents, the user can lay out part of the contents using a spatula 6 or, by inserting the lower part of a rectangular plastic metallized bag (pouch) into slot 4, turn the bag over and, holding the bag by the bottom with his left hand, move his right hand with with the back part 2 of tool 1 clamped in it in the “down” direction, squeeze the contents of the bag onto a plate for feeding the animal.

Tests of prototypes confirmed the industrial applicability of the utility model and its compliance with the declared technical results.

In particular, the possibility of obtaining a neat linear cut of the top of the bag in one movement has been repeatedly confirmed in practice, due to the placement of the blade near the peripheral end of the working part and the limitation of the possibility of transverse movement of the walls of the top of the bag, sandwiched between the walls of the slot (see Fig. 3).

In particular, it has been proven to be practical to use a spatula formed at the peripheral end of the tool to mix and partially empty the contents of the pouch, to flatten the contents of the pouch placed on a pet dish, to extract the contents from the corners of the pouch.

In particular, it was confirmed in practice the most complete release of the bag from the contents using the proposed tool.
