Food bag squeezer

Abstract

To provide a squeezer / scraper for a bag containing food, capable of scraping out all the contents of processed food contained in the bag. [Solution] The central scraping bar and the squeezing bar sections on the left and right sides of the scraping bar are arranged in parallel with a specified gap between them, and their bases are connected by a connecting means that can rotate approximately 90°. When the left and right squeezing bar sections are in a pressed state where they can come into contact with each other on the underside of the scraping bar section due to an external force that can rotate and press them, only the scraping bar sections are visible in a plan view, and when viewed from the side, the tip section forms a sloped tip surface that becomes more rearward as it goes downward from the tip of the top surface of the scraping bar section to the bottom end of the squeezing bar section. When in a pressed state, the sloped surfaces of the squeezing bar section and the left and right scraping bar sections, and the inner surfaces of the left and right scraping bar sections, squeeze the film of the food bag between them, while the top surface of the scraping bar section scrapes out the contents of the food bag. This has been solved by a squeezer / scraper for food bags.

DETAILED DESCRIPTION OF THE INVENTION

[0014] The food bag squeezer 1 of the present invention is capable of removing all of the contents of a food bag, such as a pouch containing a cooked food such as a retort pouched food, or a package containing processed foods such as pickled vegetables (fukujinzuke) or pickled ginger, from a food bag 10, and is particularly capable of removing all of the contents 11, such as small pieces of pickled vegetables (fukujinzuke) or pickled ginger, that are stuck to the inner surface of the film of the food bag 10. The food bag 10 may be, for example, as shown in Figures 10 to 14, a square-shaped bag made of two overlapping films with a thermocompression-sealed portion 10a around its periphery. Since the two films are bonded together at the periphery of the bag with the thermocompression-sealed portion 10a, the tip of the food bag squeezer 1 must be tapered in order to contact the periphery.

[0015] As shown in Figures 1 to 7 and 16 to 18, the squeezer / scraper 1 for food-containing bags of the present invention is a squeezer / scraper for food-containing bags that has three rod-shaped bodies that are parallel in the longitudinal direction and that squeeze and scrape out the contents 11 from the food-containing bag 1, and the three rods are configured in parallel with a predetermined gap 20 between a central scraping bar 2 and left and right squeezing bar sections 3 and 4 of the scraping bar section 2, and the roots of the three rods are arranged approximately parallel so that the left and right squeezing bar sections 3 and 4 are below or alongside the scraping bar section 2. The scraping rod 2 is connected by a connecting means 5 that can rotate 90°, and the scraping rod portion 2 has a tip portion 2c that is approximately bow-shaped, and a long triangular rod-like portion 2s that is connected to the tip portion 2c and has a triangular cross section with a flat upper surface 2a and a sloping side surface 2b, and the left and right squeezing rod portions 3, 4 are configured so that the longitudinal positions of the tips 3e, 4e are approximately the same as the position near the rear end of the tip portion 2c of the scraping rod portion 2, and tip portions 3d, 4d that form insertion guide surfaces for the film of the food-containing bag 10, and the The scraping bar 2 has long trapezoidal rod-shaped sections 3s, 4s with an approximately trapezoidal cross section, with inclined surfaces 3a, 4a on the upper surface that are parallel to the inclined surface of the side surface 2b, and with inner surfaces 3b, 4b and outer surfaces 3c, 4c parallel to each other. When the left and right squeezing bar sections 3, 4 are in a pressed state where they can come into contact with each other under the scraping bar section 2 due to an external force that can rotate and press them, only the scraping bar section 2 is visible in a plan view, and when viewed from the side, the tip section S extends from the tip 2d of the upper surface 2a of the scraping bar section 2 to the lower end of the squeezing bar sections 3, 4. In the pressed state, the two inclined surfaces 2b of the squeezing rod portion 2 and the inclined surfaces 3a, 4a of the left and right scraping rod portions 3, 4, and the inner surfaces 3b, 4b of the left and right scraping rod portions 3, 4 pinch and squeeze the film of the food bag 10, making it possible to scrape out the contents 11 from the food bag 10 using the flat surface that is the upper surface 2a of the scraping rod portion 2.

[0016] In food bag squeezer / scraper 1, scraping bar 2 located in the center and squeezing bars 3 and 4 located on either side of scraping bar 2 are arranged in parallel with a gap 20 that allows the scraping bars 3 and 4 to be inserted and clamped through the film of food bag 10, and that allows the squeezing bars 3 and 4 to be rotated approximately 90 degrees so that they are positioned below scraping bar 2. As shown in Figures 1 to 3 and 5, a person attempting to scrape out contents 11 contained in food bag 10 may grasp connecting means 5 and rotate squeezing bars 3 and 4 approximately 90 degrees to apply further pressure, or as shown in Figures 4 and 6 to 8, a person attempting to scrape out contents 11 contained in food bag 10 may rotate scraping bar 2 and squeezing bars 3 and 4 approximately 90 degrees to widen them and create gap 20 between them when attempting to clamp the film of food bag 10. As shown in Figure 2, the rear end is provided with a hanging part 15 for storing the food bag squeezer / scraper 1, and for example, a ring body passed through the opened hole is hung from a hanger installed on a wall or the like for storage.

[0017] The connecting means 5 will now be described. As shown in FIGS. 1 to 3, the connecting means 5 is a thin, flexible sheet-like material that is resistant to repeated bending and can be bonded with an adhesive, and examples of such materials include polyurethane film, polyimide film, and polyester film. The connecting means 5 is bonded to the scraping rod 2 and the squeezing rods 3 and 4 with an adhesive. The connecting means 5 is a portion that is gripped by a person's hand. When a person grips the connecting means 5 and rotates the squeezing rods 3 and 4 by approximately 90 degrees, the left and right squeezing rods 3 and 4 are positioned below the scraping rod 2, as shown in FIGS. 1 to 3 and 5. When the person rotates the connecting means 5 by 90 degrees in the opposite direction to the previous direction so that the three rods are aligned side by side, a gap 20 is formed between the scraping rod 2 and the squeezing rods 3 and 4, as shown in FIGS. 4 and 6 to 8. An example of an external force that can rotate and press the connecting means 5 is a human hand.

[0018] The scraping bar 2 will now be described. As shown in Figures 1, 2, 4, and 16, the scraping bar 2 has a tip 2c that is roughly bow-shaped, and a long triangular bar-like section 2s that is connected to the tip 2c and has a triangular cross section and a flat upper surface 2a and sloping side surfaces 2b. The roughly bow-shaped tip 2c of the scraping bar 2 has the flat upper surface 2a gradually tapered to form a rounded tip 2d, and the slope of the side surface 2b gradually tapered in thickness in the height direction H to form a curved slope from the tip 2d to the triangular bar-like section 2s, i.e., a tip slope 2f, and a slope 2e that is connected to the tip slope 2f.

[0019] The tip 2c of the scraping rod portion 2 is tapered in a plan view and has a rounded tip 2d, so that the flat surface of the upper surface 2a is moved along the peripheral edge of the food bag 10 where the two sheets of film are heat-pressed together, as shown in Figures 10 to 14, making it possible to scrape out food from every corner without tearing the film of the food bag 10. Furthermore, the slope of the side surface 2b is rounded at the tip 2d when viewed from the side, and has a shape that becomes thinner in the height direction H as it approaches the tip, and also gradually becomes wider in the width direction W as it moves from the tip to the rear, forming a tip inclined surface 2f and an inclined surface 2e that continues from the tip inclined surface 2f.This is because, when the tip 2d of the scraping rod portion 2 is moved along the periphery of the food bag 10, if there is a thickness in the height direction H at the tip 2d, the two sheets of film will stick together during the thermocompression processing of the food bag 10, making it difficult for the upper surface 2a of the tip 2d to abut against the narrow periphery, so by narrowing the width and making the thickness of the tip 2d, it is possible to ensure that the upper surface 2a of the tip 2d abuts against the periphery of the food bag 10.

[0020] In addition, the flat surface of the upper surface 2a of the scraping rod portion 2 can scrape out all of the contents 11, such as small pieces of fukujinzuke pickles and small pieces of pickled ginger, that are stuck to the inner wall of the film of the food bag 10, as shown in Figures 10 to 15.

[0021] The material of the scraping rod 2 is preferably a lightweight, moderately flexible material with high bending strength, with plastic being preferred. When inserting the tip of the scraping rod 2 through the opening of the food bag 10, it is easier to insert it if it is flexible rather than rigid. Examples of such plastic include ABS resin, acrylic, and bakelite. The squeezing rods 3 and 4 are preferably made of the same material as the scraping rod 2.

[0022] Next, a description will be given of the squeezing rod portions 3, 4. As shown in Figures 3(b), 7, 16 and 17, the left and right squeezing rod portions 3, 4 are configured so that the longitudinal positions of the tips 3e, 4e are approximately the same as the position near the rear end of the tip 2c of the scraping rod portion 2, and have tip portions 3d, 4d that form insertion guide surfaces for the film of the food bag 10, and long trapezoidal rod-like portions 3s, 4s that are continuous with the tip portions 3d, 4d and have slopes 3a, 4a on their upper surfaces that are parallel to and face the slope of the side surface 2b of the scraping rod portion 2, and have inner surfaces 3b, 4b and outer surfaces 3c, 4c that are approximately trapezoidal in cross section.

[0023] The tip portions 3d, 4d of the squeezing rod portions 3, 4 form insertion guide surfaces, and in a side view from the outside in the width direction W, the outer surfaces 3c, 4c have tips 3e, 4e at positions approximately the same height as the height near the lower end of the scraping rod portion 2, and on the U side above the tips 3e, 4e form arc-shaped edges 3j, 4j that are convex upward U toward a position approximately the same in the longitudinal direction as the rear end vicinity of the tip portion 2c of the scraping rod portion 2, and on the V side below the tips 3e, 4e form arc-shaped edges 3j, 4j that are convex upward U toward a position approximately the same in the longitudinal direction as the rear end vicinity of the tip portion 2c of the scraping rod portion 2, and The inner surfaces 3b, 4b form inclined tip surfaces 3f, 4f that become more rearward as they extend downward V from the tip 3e, 4e to the lower ends of the squeezing rods 3, 4, and when viewed from the inside in the width direction W, the inner surfaces 3b, 4b form inner inclined surfaces 3g, 4g that are thinner in thickness in the width direction W from the middle of the height direction H of the inclined tip surfaces 3f, 4f toward the tips 3e, 4e, with a width between the tips 3e, 4e and approximately the center of the convex arc-shaped edge portions 3j, 4j, and form inner upper inclined surfaces 3h, 4h that are rounded downward from the edge portions 3j, 4j. The inner upper inclined surfaces 3h, 4h and the inner inclined surfaces 3g, 4g, together with the inclined surface 2e of the scraping rod 2, constitute the insertion guide surface.

[0024] The squeezing rods 3, 4 have slopes 3a, 4a on one side of the roughly trapezoidal cross section that are parallel to and face the slope of the side surface 2b of the scraping rod 2, and the inner surfaces 3b, 4b of the squeezing rods 3, 4 can be pressed together so that they can come into contact with each other, in order to squeeze out the food by pinching and applying pressure to the two films on the front and back of the food bag 10. As a result, the scraping rod 2 scrapes out small pieces of fukujinzuke pickles and pickled ginger, which make up the contents 11, while squeezing and squeezing out the two films on the front and back of the food bag 10, so that the scraping rod 2 can scrape out the contents 11 thoroughly when scraping.

[0025] Furthermore, the squeeze rods 3, 4, when pressed against the film of the food bag 10, have a moment of inertia that prevents deformation during movement. This is because, when the squeeze rods 3, 4 are rotated 90° and brought closer together and moved through the food bag 10 while maintaining the film pressed against them, if the squeeze rods 3, 4 deform due to insufficient rigidity, a gap will form between the film and the squeeze rods 3, 4, making it difficult to squeeze out all of the contents 11. The moment of inertia is determined by the thickness in the width direction W of the squeeze rods 3, 4 and the length in the height direction H. Therefore, to ensure a predetermined moment of inertia, the squeeze rods 3, 4 are manufactured by determining the height in the height direction H based on the thickness of the purchased plastic material, for example.

[0026] In a pressed state in which the left and right squeezing rod portions 3, 4 are rotated approximately 90° by an external force that can rotate and press them, allowing them to come into contact with each other below the scraping rod portion 2, in a planar view, as shown in Figure 1 or Figure 15, only the scraping rod portion 2 is visible along its entire longitudinal length, and in a side view, as shown in Figure 2, the tip portion S forms a tip inclined surface 2f of the scraping rod portion 2 and tip inclined surfaces 3f, 4f of the squeezing rod portions 3, 4, which are inclined surfaces that become more rearward as they extend downward V from the tip 2d of the upper surface 2a of the scraping rod portion 2 to the lower ends of the squeezing rod portions 3, 4, and the tip inclined surfaces 2f and 3f, or 2f and 4f (not shown) are formed in an approximately straight line in a side view.

[0027] The reason for forming the inclined tip surfaces 2f and 3f and the inclined tip surfaces 2f and 4f that are slanted backward from the upper U to the lower V so as to form approximately a straight line in a side view is that when the food-containing bag 10 is moved while being brought into contact with the periphery where the two front and back layers are joined together by the thermocompression processing, if the tip 2c of the scraping rod portion 2 and the tips 3e and 4e of the squeezing rod portions 3 and 4 form a vertical surface that is perpendicular to the upper surface 2a of the scraping rod portion 2, it would be difficult for the upper surface 2a of the tip 2d of the scraping rod portion 2 to come into contact with the periphery of the food-containing bag 10. However, by forming the inclined tip surfaces 2f and 3f or the inclined tip surfaces 2f and 4f as described above, the upper surface 2a of the tip 2d of the scraping rod portion 2 can be reliably brought into contact with the periphery of the two sheets of film joined together by the thermocompression processing portion 10a of the food-containing bag 10.

[0028] When viewed from the outside in the width direction W, the outer surfaces 3c, 4c have tips 3e, 4e at positions approximately the same height as the height near the lower end of the scraping bar portion 2, and the upper U side of the tips 3e, 4e form arc-shaped edge portions 3j, 4j that are convex upward U toward a position approximately the same in the longitudinal direction as the rear end vicinity of the tip 2c of the scraping bar portion 2, and the lower V side of the tips 3e, 4e form tip inclined surfaces 3f, 4f that become more rearward as they go downward V from the upper end of the scraping bar portion 2 to the lower end of the squeezing bar portions 3, 4, and when viewed from the inside in the width direction W, the inner surfaces 3b, 4b are formed with a width between the tips 3e, 4e and approximately the center of the convex arc-shaped edge portions 3j, 4j, The inner inclined surfaces 3g, 4g are formed so that the thickness in the width direction W becomes thinner from halfway in the height direction H of the tip inclined surfaces 3f, 4f towards the tips 3e, 4e, and the inner upper inclined surfaces 3h, 4h are formed with rounded edges on the inside of the edges 3j, 4j. This is to make it easier to insert the tip 2c of the scraping rod portion 2 into the food bag 10 through an opening made by cutting near one edge of the food bag 10 between the tip 2c of the scraping rod portion 2 and the tips 3d, 4d of the squeezing rod portions 3, 4, and to insert the film of the food bag 10 between the tip 2c and the tips 3d, 4d of the squeezing rod portions 3, 4.

[0029] As described above, the squeezer / scraper 1 for food-containing bags of the present invention is characterized in that it has both a scraping function and a squeezing function.

[0030] Next, an example of use will be described. As shown in Figures 4, 6, and 7, the connecting means 5 is rotated approximately 90° by hand using an external force to spread the three rods side by side, forming gaps 20 between the scraping rod 2 and the left and right squeezing rods 3 and 4, and the film of the food bag 10 is inserted into the gaps 20 as shown in Figure 8.

[0031] 9, the connecting means 5 is grasped by a hand as an external force, and the left and right squeezing rods 3, 4 are rotated 90° to apply pressure, so that the front and back sheets of film of the food-containing bag 10 are sandwiched between the inclined surface 2b of the squeezing rod 2 and the inclined surfaces 3a, 4a of the scraping rods 3, 4, and between the inner surfaces 3b, 4b of the left and right scraping rods 3, 4. Then, pressure is applied with force from the hand.

[0032] Next, as shown in Figure 10, with the flat surface that is the upper surface 2a of the scraping bar 2 facing in the direction of travel, the scraping bar 2 is moved from the upper end of the periphery on one side of the food-containing bag 10 along the periphery of the food-containing bag 10 while contacting the tip 2d against the periphery. The periphery of the two films of the food-containing bag 10, which has the heat-compressed portion 10a on the periphery, is narrow because it is near where the two films are joined, but the tip 2c of the scraping bar 2 is tapered, and tip inclined surfaces 2f and 3f and tip inclined surfaces 2f and 4f are formed, which are inclined backward as they go downward from the tip 2d, so that the tip 2d can be firmly contacted against the narrow periphery.

[0033] Then, when it reaches the lower edge of the periphery on one side as shown in Figure 11, it is moved while still in contact with the periphery of the bottom side as shown in Figure 12. In this way, the tip 2d can be made to firmly contact the corners inside the food-containing bag 10, which has the heat-compressed portion 10a on the periphery, so that all the food can be scraped out without being left behind.

[0034] 15, when the food bag squeezing and scraping device 1 is viewed from the direction of movement as it moves through the food bag 10, the squeezing rods 3 and 4, which are pressed by hand as an external force, pinch the front film of the food bag 10, the scraping rod 2, and the back film, thereby restricting the inside of the food bag 10 with the squeezing rods 3 and 4. The upper surface 2a of the scraping rod 2 scrapes out the contents 11 within the restricted area, so that all of the contents are scraped out.

Claims

1. A food bag squeezer / scraper that squeezes and scrapes out the contents of a food bag and has three rod-shaped bodies that are parallel in the longitudinal direction, The three rods are configured with a central scraping bar portion and left and right squeezing bar portions of the scraping bar portion, which are parallel to each other with a predetermined gap between them, and the root portions of the three rods are connected by a connecting means that can rotate approximately 90° so that the left and right squeezing bar portions are below or side by side with the scraping bar portions, The scraping bar portion has a tip portion having a substantially bow shape, and a long triangular bar portion having a triangular cross section and a flat upper surface and a sloped side surface, which continues from the tip portion, The left and right squeezing rod portions are configured so that the longitudinal position of the tip is substantially the same as the position near the rear end of the tip of the scraping rod portion, and each has a tip portion that forms an insertion guide surface for the film of the food bag, and a long trapezoidal rod portion that continues from the tip portion and has a sloped upper surface that is parallel to and faces the sloped side surface of the scraping rod portion, and has a substantially trapezoidal cross section with parallel inner and outer surfaces, In a pressed state in which the left and right squeezing rod portions can come into contact with each other on the underside of the scraping rod portion due to an external force that can rotate and press, only the scraping rod portion is visible in a plan view, and in a side view, the tip portion forms a tip inclined surface that becomes more rearward as it goes downward from the tip of the upper surface of the scraping rod portion to the lower end of the squeezing rod portion, In the pressed state, the film of the food bag is squeezed by the two inclined surfaces of the squeezing rod portion and the respective inclined surfaces of the left and right scraping rod portions, and by the inner surfaces of the left and right scraping rod portions, while the contents of the food bag are scraped out by the flat upper surface of the scraping rod portion.

2. The tip of the scraping bar portion has a shape in which the flat surface of the upper surface gradually tapers to have a rounded tip, and the slopes of the left and right side surfaces gradually taper in thickness in the height direction to have rounded tips, and form convex inclined surfaces that are curved and inclined so as to bulge outward from the tip toward the triangular bar-shaped portion, The tip of the squeezing bar portion, when viewed from the outside in the width direction, has a tip at a position approximately the same height as the height near the lower end of the scraping bar portion, and above the tip, forms an arc-shaped edge that is convex upward toward a position approximately the same position in the longitudinal direction as the rear end of the tip of the scraping bar portion, and below the tip, forms a tip inclined surface that becomes more rearward as it goes downward from the tip of the upper surface of the scraping bar portion to the lower end of the squeezing bar portion, The food bag squeezer and scraper according to claim 1, characterized in that, when viewed from the inside in the width direction, the inner inclined surface is formed along the inner edge of the tip inclined surface, rearward of the edge, and the thickness in the width direction becomes thinner from the middle of the height direction of the tip inclined surface toward the tip.

3. The squeezer for food bags according to claim 1 or 2, characterized in that the squeezer rod portion, when pressed against the film of the food bag, has a second moment of area that does not deform when moved.
