Abstract

To provide a squeezer/scraper for food bags that can scrape out all of the contents of processed food contained in the food 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 predetermined 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 section is 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.

Description

The present invention relates to a food bag squeezer/scraper that can remove all of the contents of a pouch containing cooked food such as retort food, or a pack containing processed food such as fukujinzuke pickles or pickled ginger.

Patent Document 1 discloses a bag content squeezer in which two recesses are formed on each of the opposing sides of a support, and two elastic rollers are installed in the recesses so that they are parallel to and in contact with each other and are held between movable fixing members, with a handle attached to one end of one of the rollers.

Patent Document 2 discloses tongs for handling packaging bags, comprising a pair of elongated first and second members having distal and proximal ends, and a joint portion that connects the proximal ends while maintaining the distal ends spaced apart. The distal ends of the first and second members are formed with gripping portions that come into contact with or close to each other when the first and second members are closed, enabling the tongs to grip the packaging bag. At least one of the distal ends is provided with a rotatably supported blade portion, and when the blade portion is in use, the blade portion can be rotated and fixed in a state where it is exposed toward the distal end opposite the distal end where the blade portion is provided. When the blade portion is not in use, the blade portion can be rotated and stored within the distal end where the blade portion is provided.

The invention in Patent Document 1 uses elastic rollers to sandwich the contents, so most of the contents can be removed, but there is a problem in that small pieces of fukujinzuke pickles and pickled ginger stick to the inner surface of the plastic film, which is made of polypropylene, polyethylene, or other plastics, and remain inside the pack.

The device in Patent Document 2 involves squeezing the contents between two rods, but there is a problem in that small pieces of fukujinzuke pickles and pickled ginger stick to the inside of the film made of plastic such as polypropylene or polyethylene and remain inside the pack without being able to be removed.

The present invention was conceived in light of these problems, and its objective is to provide a food bag squeezer/scraper that can thoroughly scrape out the contents of food bags, such as retort pouch foods and other prepared foods contained in pouches and other food bags, and processed foods such as fukujinzuke pickles and pickled ginger contained in packs and other food bags.

In this invention, the terms "height," "inner," "outer," "upper," and "lower" refer to the directions of the food bag squeezer/scraper when the connecting means is grasped by hand as an external force, rotated 90 degrees, and further pressure is applied, with the flat surface of the scraping rod facing upward. Furthermore, the term "width" refers to the short side.

The squeezer/scraper for food bags according to claim 1 is a squeezer/scraper for food bags that includes three parallel rods extending in the longitudinal direction and that squeezes and scrapes out the contents of the food bag. The three rods are configured with a central scraper section and left and right squeezer sections of the scraper section, which are parallel with a predetermined gap between them. The bases of the three rods are connected by a connecting means that can rotate approximately 90 degrees so that the left and right squeezer sections are below or side-by-side with the scraper sections. The squeezer sections have a tip section that is approximately bow-shaped, and a long triangular section that has a triangular cross-section and a flat upper surface and sloped sides, continuing from the tip section. The left and right squeezer sections are configured so that the longitudinal position of the tip is approximately the same as the position near the rear end of the tip of the squeezer section. The tip section forms an insertion guide surface for the film of the food bag, and the tip section has a The device further comprises a long, trapezoidal rod-shaped section with an approximately trapezoidal cross section and parallel inner and outer surfaces, and an upper surface that is a slope that faces parallel to the slopes of the side surfaces of the scraping rod sections. When the left and right squeezing rod sections are in a pressed state where they can come into contact with each other below the scraping rod sections due to an external force that can rotate and press them, only the scraping rod sections are visible in a plan view, and when viewed from the side, the tip sections form a sloped tip that becomes more rearward as it extends downward from the tip of the top surface of the scraping rod section to the bottom end of the squeezing rod section. In this pressed state, the two sloped surfaces of the squeezing rod section and the respective sloped surfaces of the left and right scraping rod sections, and the inner surfaces of the left and right scraping rod sections, sandwich and squeeze the film of the food bag, making it possible to scrape out the contents of the food bag using the flat upper surfaces of the scraping rod sections.

The squeezing and scraping device for bags containing food according to claim 2 is the same as that according to claim 1, wherein the tip of the scraping bar is such that the flat surface of the upper surface gradually tapers to form a rounded tip, and the slopes of the left and right side surfaces gradually taper in thickness in the height direction to form rounded tips, and form convex inclined surfaces that curve outward from the tip toward the triangular bar-shaped portion, and the tip of the squeezing bar has an outer surface that, when viewed from the outside in the width direction, has a tip that is at approximately the same height as the height near the bottom end of the scraping bar. The side above the tip forms an arc-shaped edge that is convex upward toward a position that is approximately the same in the longitudinal direction as the rear end of the tip of the scraping bar portion, and the side 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, and when viewed from the side from the inside in the width direction, it forms an inner inclined surface that is formed along the inner edge of the tip inclined surface and is rearward of the edge, and the widthwise thickness of the tip inclined surface becomes thinner from midway in the height direction towards the tip.

The food bag squeezer and scraper described in claim 3 is the same as claim 1 or 2, but is characterized in that the squeezer rod, when pressed against the film of the food bag, has a second moment of area that prevents deformation when moved.

The food bag squeezer and scraper of the present invention has the dual functions of squeezing food out of the food bag by pinching and applying pressure to the two film sheets of the food bag, and scraping out the food contents of the food bag by inserting it into the food bag. The two squeezing rods clamp and apply pressure to the two film sheets on the front and back of the food bag and the scraping rod, restricting the space between the front and back films of the food bag, forcing the contents into this restricted space, and then scraping out the pushed-in contents with the scraping rod. This provides the remarkable effect of being able to remove all of the contents from pouches containing cooked foods such as retort foods, or from packs containing small pieces of processed food such as fukujinzuke pickles and pickled red ginger.

The food bag squeezer/scraper 1 of the present invention is capable of removing all of the contents of a food bag (10), such as a pouch containing a prepared food such as a retort pouch, or a pack containing processed foods such as fukujinzuke pickles or pickled red ginger, from the food bag (10). It is particularly capable of removing all of the contents (11), such as small pieces of fukujinzuke pickles or pickled red ginger, that are stuck to the inner surface of the film of the food bag (10). The food bag (10), as shown in Figures 10 to 14, has a rectangular outer shape and is made of two overlapping sheets of film with a thermocompression-sealed portion (10a) around the periphery. Since the two sheets of film are bonded together at the periphery of a bag with the thermocompression-sealed portion (10a), the tip of the food bag squeezer/scraper 1 must be tapered in order to contact the periphery.

As shown in Figures 1 to 7 and 16 to 18, the food bag squeezer/scraper 1 of the present invention is a squeezer/scraper for food bags that has three parallel rods in the longitudinal direction, which squeeze and scrape out the contents 11 from the food bag 1. The three rods are configured parallel to each other with a predetermined gap 20 between the central scraper rod 2 and the left and right squeezer rods 3 and 4 of the scraper rod 2, and the roots of the three rods are approximately oriented such that the left and right squeezer rods 3 and 4 are below or alongside the scraper rod 2. The scraping rod 2 is connected by a connecting means 5 that can rotate 90°, and the scraping rod 2 has a tip 2c that is approximately bow-shaped, and a long triangular rod-like portion 2s that is connected to the tip 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 rods 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 2, and tip portions 3d, 4d that form insertion guide surfaces for the film of the food-containing bag 10, and the The scraping rod 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 surfaces of the side surface 2b of the scraping rod section 2, and with inner surfaces 3b, 4b and outer surfaces 3c, 4c parallel to each other. When the left and right squeezing rod sections 3, 4 are in a pressed state where they can come into contact with each other below the scraping rod section 2 due to an external force that can rotate and press them, only the scraping rod 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 rod section 2 to the lower end of the squeezing rod sections 3, 4. In the pressed state, the film of the food bag 10 is sandwiched and squeezed by the two sloped surfaces 2b of the squeezing rod 2 and the sloped surfaces 3a and 4a of the left and right scraping rods 3 and 4, respectively, and by the inner surfaces 3b and 4b of the left and right scraping rods 3 and 4, while the contents 11 from the food bag 10 are scraped out by the flat upper surface 2a of the scraping rod 2.

The food bag squeezer/scraper 1 is configured with the scraping bar 2 located in the center and the squeezing bars 3 and 4 located on either side of the scraping bar 2, arranged parallel to each other with a gap 20 that allows the scraping bar 3 and 4 to be inserted and clamped through the film of the food bag 10, and to rotate the scraping bar 3 and 4 approximately 90 degrees so that they are positioned below the scraping bar 2. As shown in Figures 1 to 3 and 5, a person attempting to scrape out the contents 11 contained in the food bag 10 can grasp the connecting means 5 and rotate the squeezing bar 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 the contents 11 contained in the food bag 10 can rotate the scraping bar 2 and the squeezing bar 3 and 4 approximately 90 degrees to widen the gap 20 between them when attempting to clamp the film of the food bag 10. As shown in Figure 2, the rear end is provided with a hanging section 15 for storing the food bag squeezer/scraper 1; for example, a ring passed through the hole is hung from a hanger attached to a wall or the like.

The connecting means 5 will now be described. As shown in Figures 1 to 3, the connecting means 5 is a thin, flexible sheet that can withstand repeated bending and can be adhesively bonded. Examples include polyurethane film, polyimide film, and polyester film. The connecting means 5 is adhesively bonded to the scraping bar 2 and the squeezing bar sections 3 and 4. The connecting means 5 is the part that is gripped by a person's hand. When a person grasps the connecting means 5 and rotates the squeezing bar sections 3 and 4 approximately 90 degrees, the left and right squeezing bar sections 3 and 4 are located below the scraping bar section 2, as shown in Figures 1 to 3 and 5. When a person rotates the connecting means 5 90 degrees in the opposite direction to the previous direction so that the three sections are aligned side by side, a gap 20 is formed between the scraping bar section 2 and the squeezing bar sections 3 and 4, as shown in Figures 4 and 6 to 8. An example of an external force that can rotate and compress is a human hand.

The scraping bar portion 2 will now be described. As shown in Figures 1, 2, 4, and 16, the scraping bar portion 2 has a roughly bow-shaped tip portion 2c and a long, triangular bar-shaped portion 2s, continuing from the tip portion 2c, that has a triangular cross-section and a flat upper surface 2a and sloping side surfaces 2b. The roughly bow-shaped tip portion 2c of the scraping bar portion 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 toward the triangular bar-shaped portion 2s, i.e., a tip slope 2f, and a slope 2e continuing from the tip slope 2f.

The tip 2c of the scraping rod 2 is tapered in plan view and the tip 2d is rounded so that, as shown in Figures 10 to 14, 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-sealed together, making it possible to scrape out food from every corner without tearing the film of the food bag 10. Additionally, the slope of the side surface 2b is rounded at the tip 2d when viewed from the side, and has a shape that tapers in height H towards the tip and gradually widens in width W from the tip towards the rear, forming a tip slope 2f and a slope 2e that continues from the tip slope 2f. This is because, when the tip 2d of the scraping rod 2 is moved along the periphery of the food-containing bag 10, if the tip 2d is thick in height H, the two sheets of film will stick together during the thermocompression process of the food-containing bag 10, making it difficult for the top surface 2a of the tip 2d to abut against the narrow periphery; therefore, by narrowing the width and making the thickness of the tip 2d thinner, the top surface 2a of the tip 2d can reliably abut against the periphery of the food-containing bag 10.

In addition, as shown in Figures 10 to 15, 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 pickled vegetables or small pieces of pickled ginger, that are stuck to the inner wall of the film of the food bag 10.

The material for the scraping rod 2 is preferably light, moderately flexible, and has 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 plastics include ABS resin, acrylic, and bakelite. The squeezing rods 3 and 4 are preferably made of the same material as the scraping rod 2.

Next, the squeezing rods 3, 4 will be described. As shown in Figures 3(b), 7, 16, and 17, the left and right squeezing rods 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 2. They have tips 3d, 4d that form insertion guide surfaces for the film of the food bag 10, and long trapezoidal rod-shaped sections 3s, 4s that are continuous with the tips 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 2, and have inner surfaces 3b, 4b and outer surfaces 3c, 4c that are parallel to each other, with a generally trapezoidal cross section.

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

The squeezing rods 3 and 4 have slopes 3a and 4a on one side of the roughly trapezoidal cross section that are parallel to the slope of the side surface 2b of the scraping rod 2, and the inner surfaces 3b and 4b of the squeezing rods 3 and 4 can be pressed together to allow contact between them. This allows the two films on the front and back of the food bag 10 to be squeezed and squeezed while being pressed. As a result, the scraping rod 2 scrapes out small pieces of the contents 11, such as pickled vegetables and red pickled ginger, while squeezing and squeezing the two films on the front and back of the food bag 10. This allows the scraping rod 2 to thoroughly scrape out the contents 11.

Furthermore, the squeeze rods 3, 4, when pressed against the film of the food bag 10, have a second moment of area that prevents deformation during movement. This is because when the squeeze rods 3, 4 are rotated 90° and brought closer together, and then 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 second moment of area 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, in order to ensure a predetermined second moment of area, the squeeze rods 3, 4 are manufactured by calculating the height in the height direction H based on the thickness of the purchased plastic material, for example.

When the left and right squeezing rods 3, 4 are rotated approximately 90° by an external force that can rotate and press them, and they are in a pressed state where they can come into contact with each other below the scraping rod 2, in a plan view, as shown in Figure 1 or Figure 15, only the scraping rod 2 is visible along its entire longitudinal length. In a side view, as shown in Figure 2, the tip S forms a sloped surface that slopes downward V from the tip 2d of the upper surface 2a of the scraping rod 2 to the lower ends of the squeezing rods 3, 4, forming a sloped tip surface 2f of the scraping rod 2 and sloped tip surfaces 3f, 4f of the squeezing rods 3, 4, and the sloped tip surfaces 2f and 3f, or 2f and 4f (not shown), are formed in a substantially straight line in a side view.

The tip inclined surfaces 2f and 3f, and tip inclined surfaces 2f and 4f, are angled backward from the upper U to the lower V so as to form a generally straight line in side view. When the scraping rod 2 is moved along the periphery of the food-containing bag 10 where the two front and back layers are joined by thermocompression, if the tip 2c of the scraping rod 2 and the tips 3e and 4e of the squeezing rods 3 and 4 form vertical surfaces perpendicular to the top surface 2a of the scraping rod 2, it would be difficult for the top surface 2a of the scraping rod 2 to come into contact with the periphery of the food-containing bag 10. However, by forming the angled tip inclined surfaces 2f and 3f, or tip inclined surfaces 2f and 4f as described above, the top surface 2a of the scraping rod 2 can be reliably brought into contact with the periphery of the two sheets of film joined by the thermocompression-sealed portion 10a of the food-containing bag 10.

When viewed from the outside in the width direction W, the outer surfaces 3c, 4c have tips 3e, 4e at approximately the same height as the vicinity of the lower end of the scraping bar 2, and above the tips 3e, 4e on the U side, form arc-shaped edges 3j, 4j that are convex upward U toward a position approximately at the same position in the longitudinal direction as the vicinity of the rear end of the tip 2c of the scraping bar 2. When viewed from the inside in the width direction W, the inner surfaces 3b, 4b have a width between the tips 3e, 4e and the approximate center of the convex arc-shaped edges 3j, 4j, and The inner inclined surfaces 3g, 4g are formed by tapering in thickness in the width direction W from midway along the height direction H of the tip inclined surfaces 3f, 4f toward the tips 3e, 4e, and the inner upper inclined surfaces 3h, 4h are rounded on the inside of the edges 3j, 4j. This is to facilitate smooth insertion and insertion when inserting the tip 2c of the scraping rod 2 into the food bag 10 through an opening created by cutting near one edge of the food bag 10 between the tip 2c of the scraping rod 2 and the tips 3d, 4d of the squeezing rods 3, 4, and when inserting the film of the food bag 10 between the tip 2c and the tips 3d, 4d of the squeezing rods 3, 4.

As mentioned above, the integrated scraping and squeezing functions are a feature of the food-containing bag squeezer/scraper 1 of the present invention.

Next, an example of use will be described. As shown in Figures 4, 6, and 7, the connecting means 5 is rotated approximately 90 degrees by hand using an external force to open it, lining up the three rods side by side, forming a gap 20 between the scraping rod 2 and the left and right squeezing rods 3 and 4. As shown in Figure 8, the film of the food bag 10 is inserted into the gap 20.

Next, as shown in Figure 9, the connecting means 5 is grasped with the hand, which is an external force, and the left and right squeezing rods 3, 4 are rotated 90 degrees and pressure is applied, so that the two front and back film sheets of the food 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.

Next, as shown in Figure 10, with the flat upper surface 2a of the scraping bar 2 facing in the direction of travel, the scraping bar 2 is moved from the top of the periphery of one end of the food bag 10 along the periphery of the food bag 10, with the tip 2d in contact with the periphery. The periphery of the two films of the food bag 10, which has the heat-compressed portion 10a on its periphery, is narrow because it is near where the two films are joined. However, the tip 2c of the scraping bar 2 is tapered, forming tip inclined surfaces 2f and 3f, and tip inclined surfaces 2f and 4f, which are inclined backward as they extend downward from the tip 2d, allowing the tip 2d to firmly contact the narrow periphery.

Then, as shown in Figure 11, when it reaches the bottom edge of the periphery on one side, 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 firmly contacted with the corners inside the food bag 10, which has the heat-compressed portion 10a on the periphery, so all the food can be scraped out without leaving any residue.

When the food bag squeezer/scraper 1 is viewed from the direction of movement as it moves through the food bag 10, as shown in Figure 15, the squeezer rods 3 and 4 are pressed by hand as an external force, clamping the front film of the food bag 10, the scraper rod 2, and the back film, thereby restricting the inside of the food bag 10 between the squeezer rods 3 and 4. The upper surface 2a of the scraper rod 2 scrapes out the restricted area, so that all of the contents 11 within the restricted area are scraped out.

Then, as shown in Figure 13, when it reaches the bottom edge of the periphery on the other end, it is moved while still in contact with the periphery on the other end, and as shown in Figure 14, all of the contents 11 can be scraped out without leaving any residue.

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. 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 widthwise thickness of the tip inclined surface becomes thinner from the middle of the height direction of the tip inclined surface toward the tip. The food bag squeezer and scraper according to claim 1 or 2, characterized in that the squeezer rod, when pressed against the film of the food bag, has a second moment of area that prevents deformation when moved.
