Description

Technical Field

[0001] The utility model relates to a container with a handle used for packaging fluid contents such as pet food and weaning food, a manufacturing method of the container with a handle, and a packaging body.

[0002] In this specification and utility model claims, Figure 2 、 Figure 3 、 Figure 7 and Figure 8 The up and down of is called up and down. Background Art

[0003] Pet food snacks are used as a tool for connecting with pets, and one of their appeals is the ability to feed them directly from their owners' hands. While dry, solid foods, such as those in sticks, are less likely to stain hands, popular semi-solid (fluid) foods containing large amounts of water can stain hands. Therefore, they are often transferred to separate feeding containers or squeezed out of stick-shaped multilayer film containers using a slider for direct delivery. However, even in these cases, the contents can stick to hands, or spill onto the floor, etc., contaminating the surrounding area, such as when the contents are squeezed out, if more than necessary is dispensed.

[0004] Therefore, as a container with a handle that allows pets to be fed directly with one hand, without squeezing the contents out of other feeding containers or sealed bags, a container with a handle has been proposed. The container comprises: a container body including a peripheral wall portion and a bottom wall portion, and having an opening surrounded by the upper end of the peripheral wall portion; a flange portion provided at the upper end of the peripheral wall portion and facing outward; and a handle portion provided so as to protrude outward from a portion of the circumference of the flange portion. The bottom wall portion, the peripheral wall portion, the flange portion, and the handle portion are integrally formed of a synthetic resin, and a reinforcing recessed portion having a predetermined length and having its longitudinal direction oriented in the longitudinal direction of the handle is formed in the handle portion (see Patent Document 1). The container with a handle is manufactured by pressure molding or vacuum molding a synthetic resin sheet.

[0007] Patent Document 1: Japanese Patent Application Laid-Open No. 2021-151878 Summary of the Invention

[0008] Problems to be solved by the invention

[0009] However, the container with a handle described in Patent Document 1 is made of resin and therefore has the following problems: insufficient barrier properties to protect the contents from gases, water vapor, light, etc., resulting in insufficient storage of the contents. Furthermore, the handle is not strong enough, causing deformation or breakage of the handle.

[0010] In view of the above-mentioned actual situation, the present invention aims to provide a container with a handle having improved barrier properties and increased handle strength, a method for manufacturing the container with a handle, and a packaging body.

[0011] Means for solving problems

[0012] In order to achieve the above-mentioned purpose, the present invention includes the following methods.

[0013] 1) A container with a handle, comprising:

[0014] The container body includes a peripheral wall portion and a bottom wall portion and has an opening surrounded by the upper end portion of the peripheral wall portion; a flange portion provided at the upper end of the peripheral wall portion and facing outward; and a handle portion provided in a manner protruding outward at a portion of the circumference of the flange portion.

[0015] The peripheral wall portion, bottom wall portion, flange portion and handle portion are integrally formed.

[0016] The container with a handle comprises a barrier layer comprising a metal foil, a base material layer comprising a synthetic resin layer and provided on one side of the barrier layer, and a heat-sealing resin layer provided on the other side of the barrier layer, wherein the heat-sealing resin layer forms the upper surface of the flange portion and the inner surface of the container body.

[0017] 2) The container with a handle as described in 1) above is a container with a handle obtained by molding a raw material. When the thickness of the flange and the handle is set to d1 mm, the thickness of the upper end of the peripheral wall of the container body is set to d2 mm, and the thickness of the portion of the container body other than the upper end of the peripheral wall is set to d3 mm, d1 is the same as the thickness of the raw material, d1>d2>d3, d2 is 60% to 80% of d1, and d3 is 45% to 65% of d1.

[0018] 3) The container with a handle according to 1) above, wherein both surfaces of the metal foil serving as the barrier layer are subjected to a chemical conversion treatment.

[0019] 4) The container with a handle according to 1) above, wherein the barrier layer comprises aluminum foil formed of an aluminum alloy containing 0.7 to 1.7 mass % of Fe and the balance consisting of Al and unavoidable impurities.

[0020] 5) The container with a handle according to 1) above, wherein the synthetic resin layer of the base material layer comprises a polyamide film.

[0021] 6) The container with a handle according to 1) above, wherein the container body is formed by embossing.

[0022] 7) The container with a handle according to 1) above, wherein a reinforcement portion is provided on the handle.

[0023] 8) The container with a handle as described in 7) above, wherein the reinforcing portion of the handle includes at least one reinforcing rib extending in the longitudinal direction of the handle, the reinforcing rib being substantially U-shaped in cross section and protruding in a downwardly concave manner and open at the top.

[0024] 9) The container with a handle according to 8) above, wherein the wing portions between the widthwise side edges of the handle and the reinforcing ribs are each bent obliquely upward.

[0025] 10) The container with a handle according to 9) above, wherein a protrusion protruding outward is integrally provided in a certain length portion on the protruding end side of the handle in the wing portion of the handle.

[0026] 11) A package comprising a container body of the container with a handle according to any one of 1) to 10) above, wherein contents are placed in the container body, the opening of the container body is sealed by a lid, and the peripheral edge of the lid is heat-sealed to the upper surface of the flange.

[0027] The method for manufacturing a container with a handle as described in any one of 1) to 10) above includes the following steps: forming a container body including a peripheral wall portion and a bottom wall portion by performing embossing processing on a raw material formed by a laminated material, then forming a flange portion at the upper end portion of the peripheral wall portion of the container body, and cutting the raw material in a manner such that a handle protruding outward is formed on a part of the circumference of the flange portion, thereby punching out the container with a handle, wherein the laminated material includes: a barrier layer including a metal foil; a base material layer provided on one side of the barrier layer and including a synthetic resin layer; and a heat-sealed resin layer provided on the other side of the barrier layer.

[0028] The above method includes the following steps: in a strip-shaped raw material formed by the aforementioned laminated material and having a certain width and length, a blank part including a first part, a second part and a third part is pre-arranged, the first part forming the container body, the second part surrounding the first part and forming a flange part, the third part being connected to a part of the peripheral part of the second part and forming a handle, the first part of the blank part is pressed from top to bottom around the entire circumference to be fixed, and a bulging process is performed to deform the first part in an extended manner by a punch to form the container body, and then the container body is formed. The strip-shaped laminated material is cut and a container with a handle is punched out in such a manner that the upper end of the peripheral wall portion remains as the second portion of the flange portion, and a part of the circumference of the flange portion remains as the third portion of the handle protruding outward, so that the container with a handle satisfies the following conditions: when the thickness of the flange portion and the handle portion is set to d1mm, the thickness of the upper end of the peripheral wall portion of the container body is set to d2mm, and the thickness of the portion of the container body other than the upper end of the peripheral wall portion is set to d3mm, d1 is the same as the thickness of the strip-shaped raw material before processing, d1>d2>d3, d2 is 60-80% of d1, and d3 is 45-65% of d1.

[0029] Effect of utility model

[0030] The handle containers described in 1) to 10) above include a barrier layer comprising metal foil, thereby enhancing barrier properties that protect the contents from gases, water vapor, light, and the like, ensuring adequate storage of the contents. Furthermore, the barrier layer comprising metal foil serves as a framework, with a base layer comprising a synthetic resin layer formed on one side and a heat-sealed resin layer formed on the other side. This enhances the strength of the handle, suppresses deformation and breakage, and ensures corrosion resistance.

[0031] The container with a handle described in 2) above is manufactured by a method comprising the following steps: a blank portion comprising a first portion, a second portion, and a third portion is pre-formed in a strip of material having a predetermined width and length and comprising a barrier layer, a base layer, and a heat-weld resin layer. The first portion forms the container body, the second portion surrounds the first portion and forms the flange, and the third portion is connected to a portion of the second portion's peripheral edge and forms the handle. The first portion of the blank portion is pressed from above and below around its entire circumference to secure it, and a punch is used to deform the first portion in an elongated manner to form the container body. The strip of laminated material is then cut to form a container with a handle, leaving the second portion, which becomes the flange, at the upper end of the peripheral wall of the container body, and the third portion, which becomes the outwardly protruding handle, at a portion of the flange. Consequently, wrinkles are less likely to form in the flange and handle. In addition, the thickness of the flange and handle of the manufactured handle container is basically unchanged compared with the thickness of the initial strip raw material. Only the thickness of the peripheral wall and bottom wall of the container body is thinner than the thickness of the initial strip raw material, resulting in the thickness relationship as described in 2) above.

[0032] Furthermore, since the outer shapes of the flange and handle of the manufactured container with a handle are basically unchanged compared to the outer shapes of the second and third parts of the blank portion of the strip raw material, multiple blank portions can be arranged in one strip raw material in the most suitable manner in terms of improving the material yield.

[0033] According to the above-mentioned 3), chemical conversion treatment is applied to both sides of the metal foil that serves as a barrier layer, so that the packaging body with contents placed in the container body of the container with a handle, the opening of the container body is closed by a lid material, and the peripheral edge of the lid material is heat-sealed to the upper surface of the flange portion can be subjected to boiling treatment.

[0034] According to the container with a handle described in 4) above, the barrier layer includes aluminum foil formed from an aluminum alloy containing 0.7 to 1.7 mass % of Fe, with the remainder consisting of Al and inevitable impurities. This ensures sufficient strength of the handle, and also ensures sufficient strength at the connection between the container body and the handle, thereby being able to suppress deformation during feeding.

[0035] According to the container with a handle described in 5) above, since the polyamide film includes a substrate layer, the stretchability and puncture resistance of the laminated material including the barrier layer, the substrate layer, and the heat-sealing resin layer are improved. When manufactured using a method including embossing, wrinkles are less likely to form in the flange and the handle, and the container body is less likely to rupture. In addition, a polyethylene terephthalate film can be laminated on the inner surface side of the peripheral wall and bottom wall of the container body in the substrate layer, and on the upper surface side of the handle. In this case, the strength of the connection between the container body and the handle is increased, and deformation during feeding can be suppressed, thereby facilitating feeding. Furthermore, when the polyethylene terephthalate film described above is laminated, a printed layer can be provided between the polyamide film and the polyethylene terephthalate film.

[0036] According to the container with a handle described in 7) and 8), the strength of the handle is further increased, and breakage can be suppressed.

[0037] According to the above-mentioned 9) and 10) handle containers, when holding the handle during feeding, the thumbs are positioned between the two sides of the width direction of the upper surface of the handle and the two parts that are bent obliquely upward between the reinforcing ribs, and the index finger and middle finger are positioned along the lower surface of the handle, thereby making it easier to hold the handle and feeding easier.

[0038] The package described in 11) above can suppress wrinkles on the flange and handle of a container with a handle, resulting in excellent airtightness when the lid is heat-sealed to the upper surface of the flange. Furthermore, the handle is strengthened, providing excellent stability when gripped. In particular, packages containing a container with a handle described in 3) above can be retorted.

[0059] The following describes embodiments of the present invention with reference to the accompanying drawings. It should be noted that, in the drawings, for ease of understanding, the ratios of the thickness of the container body's peripheral wall, bottom wall, flange, and handle relative to the handle's length and width are larger than in actual practice. However, the technical scope of the present invention is not limited to the embodiments shown in the drawings.

[0060] Figure 1 and Figure 2 Shown is a container with a handle according to the present invention. Figure 3 A laminated material for making a container with a handle is shown. Figure 4 Shown for manufacturing Figure 1The strip-shaped raw material of the container with a handle is provided with an arrangement of blank parts.

[0061] exist Figure 1 and Figure 2 In the embodiment, the container with a handle 1 includes: a container body 2 including a peripheral wall portion 21 and a bottom wall portion 22, and having a circular opening 23 surrounded by the upper end of the peripheral wall portion 21; a flange portion 3 provided at the upper end of the peripheral wall portion 21 and facing outward; and a handle portion 4 provided so as to protrude outward from a portion of the circumference of the flange portion 3. The peripheral wall portion 21 and bottom wall portion 22 of the container body 2, the flange portion 3, and the handle portion 4 are integrally formed. The container with a handle 1 is obtained by molding a raw material.

[0062] The opening 23, bottom wall 22, and flange 3 of the container body 2, which are surrounded by the upper end of the peripheral wall 21, are circular in shape when viewed from above. The peripheral wall 21 of the container body 2 gradually tapers downward in diameter, and its lower end is connected to the bottom wall 22 via a connecting portion 24 protruding outward and having an arcuate (partially cylindrical) cross-section. Rounded corners are formed between the inner surface of the peripheral wall 21 and the upper surface of the flange 3, and between the outer surface of the peripheral wall 21 and the lower surface of the flange 3.

[0063] The thickness of the flange 3 and handle 4 is generally constant. When the thickness of the handle 4 is set to d1 mm, the thickness of the upper end of the peripheral wall 21 of the container body 2 is set to d2 mm, and the thickness of the portion of the container body 2 excluding the upper end of the peripheral wall 21 is set to d3 mm, preferably, d1>d2>d3, with d2 being 60-80% of d1 and d3 being 45-65% of d1. Furthermore, when the thickness of the bottom wall 22 is set to d4 mm, preferably, d1>d2>d3>d4, with d4 being 42-62% of d1. It should be noted that d2 represents a thickness in the range of 5-50% of the total height from the upper end of the peripheral wall 21, and d3 represents a thickness in the range from the portion having the thickness of d2 to the connecting portion 24.

[0064] The thickness of the flange 3 and the handle 4 is preferably 0.05 to 0.5 mm. If the thickness of the flange 3 and the handle 4 is less than 0.05 mm, the container body 2 is easily damaged by puncture, pinholes, etc., and thus sufficient strength as a container cannot be obtained. If the thickness exceeds 0.5 mm, the manufacturing cost becomes higher than necessary.

[0065] In addition, if the container functions such as ease of holding and ease of feeding are taken into consideration, it is preferred that the diameter of the bottom wall portion 22 of the container body 2 is 10 to 40 mm, the diameter of the opening 23 of the container body 2 is 30 to 60 mm, the bulge width of the flange portion 3 is 1 to 10 mm, the width of the handle 4 is 15 to 30 mm, and the length of the handle 4 from the periphery of the opening 23 to the front end of the handle 4 is 30 to 50 mm.

[0066] Container with handle 1 Figure 3 The laminated material 10 shown is formed, and the laminated material 10 includes: a barrier layer 11 including a metal foil; a base material layer 12 provided on one side of the barrier layer 11 and including a synthetic resin layer; and a heat-sealing resin layer 13 provided on the other side of the barrier layer 11, the heat-sealing resin layer 13 forming the uppermost surface of the flange portion 3, the uppermost surface of the handle portion 4, and the innermost surface of the container body 2.

[0067] The barrier layer 11 of the laminate 10 protects the contents of the package from gases, water vapor, light, and the like. The opening 23 of the handle container 1 in the package is sealed by a lid, the peripheral edge of which is heat-sealed to the flange 3. The barrier layer 11 comprises a metal foil formed from a metal such as aluminum (including aluminum alloys, the same applies hereinafter), copper (including copper alloys), iron (stainless steel), or titanium. Aluminum foil is preferably used in consideration of barrier properties, processability, and cost. Preferred aluminum foils include 1000 series aluminum materials such as A1N30 specified in JIS H4160:2006, and 8000 series aluminum materials such as A8021 and A8079. Particularly preferred are aluminum foils that meet the chemical compositions of A8021 and A8079 specified in JIS H4160:2006, have an Fe content of 0.7 to 1.7 mass%, and a Si content limited to 0.1 mass% or less.

[0068] The thickness of the barrier layer 11 is preferably 30 to 140 μm. If the thickness of the barrier layer 11 is less than 30 μm, pinholes and the like are likely to form, and the container with a handle 1 using the laminate 10 may not have sufficient barrier properties. If the thickness exceeds 140 μm, costs increase or dry lamination becomes difficult. The thickness of the barrier layer 11 is more preferably 60 to 120 μm.

[0069] It should be noted that the chromate treatment, silicate treatment, zirconium-based chemical conversion treatment and other treatment methods are used to coat both sides of the aluminum foil with a chromium coating amount of 0.1 to 50 mg / m2 per side. 2 , preferably 2 to 20 mg / m 2 It is better to form a chemical conversion film in this way.

[0070] The base layer 12 is preferably formed from a single-layer film made of, for example, polyolefin, polyester, or polyamide, or a multilayer film formed by laminating multiple single-layer films, with a thickness of 8 to 50 μm. If the thickness of the base layer 12 is less than 8 μm, it is difficult to form the container with a handle 1 using the laminated material 10. If the thickness is greater than 50 μm, the manufacturing cost becomes excessive. The thickness of the base layer 12 is more preferably 15 to 30 μm.

[0071] As the aforementioned monolayer film, an unstretched film or a biaxially stretched film can be used. As polyolefins, examples include high-density polyethylene (HDPE), low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), homopolypropylene (hPP), ethylene-propylene random copolymer (rPP), and ethylene-propylene block copolymer (bPP). As polyesters, examples include polybutylene terephthalate (PBT). In addition, examples include 6-nylon, 6.6 nylon, and MXD nylon. Among them, a biaxially stretched film comprising polyamide is preferably used. When using a polyamide film, it is preferred that a polyethylene terephthalate film be laminated on the inner surface side of the peripheral wall portion and the bottom wall portion of the container body in the base layer, and on the upper surface side of the handle portion, which is closer to the polyamide film. As a result, the strength of the connecting portion between the container body and the handle portion is increased, which can suppress deformation during feeding, making feeding easy. Furthermore, a printed layer can be provided between the polyamide film and the polyethylene terephthalate film.

[0072] The heat-sealing resin layer 13 can be formed from a polyolefin resin such as high-density polyethylene (HDPE), low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), homopolypropylene (hPP), ethylene-propylene random copolymer (rPP), or ethylene-propylene block copolymer (bPP). Unstretched polypropylene film is preferred. A three-layer unstretched polypropylene film comprising an ethylene-propylene block copolymer (bPP) film laminated on both sides with an ethylene-propylene random copolymer (rPP) film is particularly preferred. In such a three-layer structure, ethylene-propylene block copolymer (bPP) exhibits excellent low-temperature impact resistance, so even if a packaged container with a handle is dropped while stored in a refrigerator or freezer, the container with a handle will not break or rupture.

[0073] The thickness of the heat-welding resin layer 13 is preferably 20 to 300 μm. If the thickness of the heat-welding resin layer 13 is less than 20 μm, the lid material may break when heat-sealing to the flange 3. If the thickness is greater than 300 μm, it may be difficult to form the container body 2 by embossing. The thickness of the heat-welding resin layer 13 is more preferably 60 to 150 μm.

[0074] To ensure sufficient lamination strength, the barrier layer 11 and the base layer 12, as well as the barrier layer 11 and the heat-sealing resin layer 13, are preferably bonded using adhesive layers having a thickness of 0.5 to 10 μm, preferably 2 to 5 μm. Examples of adhesives used include urethane adhesives, epoxy adhesives, and olefin adhesives.

[0075] The method for manufacturing the container with a handle 1 is as follows.

[0076] First, in Figure 3 The laminated material 10 shown is formed into a strip-shaped raw material 30 having a certain length and width, as shown in FIG. Figure 4 As shown, a plurality of blank portions 31 are set so as to optimize the material yield. The blank portion 31 includes a first portion 32 that forms the container body 2; a second portion 33 that surrounds the first portion 32 and forms the flange 3; and a third portion 34 that connects to a portion of the peripheral edge of the second portion 33 and forms the handle 4.

[0077] Next, the first portion 32 of the blank portion 31 is pressed from top and bottom around the entire circumference to be fixed, and a punch is used to deform the first portion 32 in an extended manner to form a bulging process of the container body 2 including the peripheral wall portion 21 and the bottom wall portion 22.

[0078] Then, the strip-shaped laminated material 30 is cut so that the second portion 33, which will become the flange portion 3, remains at the upper end portion of the peripheral wall portion 21 of the container body 2, and the third portion 34, which will become the handle portion 4 protruding outward, remains at a portion of the circumference of the flange portion 3. The container with a handle 1 is thus manufactured.

[0079] Figure 5 The above-described container with a handle 1 is shown to have a handle with a reinforcement portion for the purpose of increasing strength.

[0080] Figure 5 The handle 40 shown in (a) includes a flat main body 41 and reinforcement portions 42 integrally provided in an upright shape on both side edges of the main body 41 .

[0081] Figure 5 The handle 50 shown in (b) includes a flat main body 51 and reinforcement portions 52 integrally provided on both side edges of the main body 51 in an upwardly folded shape.

[0082] At once Figure 5 As for the handle 60 shown in (c), the whole is a corrugated plate, and the wave top 61 and the wave bottom 62 extending in the long side direction of the handle 60 are arranged and alternately provided in the width direction of the handle 60, and the wave top 61 and the wave bottom 62 become reinforcement parts.

[0083] Figure 5 The handle portion 70 shown in (d) includes a flat main body portion 71 and rolled-edge-shaped reinforcement portions 72 provided on both side edges of the main body portion 71 so as to be rolled upward.

[0084] Figures 6 to 9 A second embodiment of the container with a handle of the present invention will be described.

[0085] exist Figures 6 to 9 In the Figure 1 and Figure 2 The same objects and parts of the illustrated container with a handle are denoted by the same reference numerals, and detailed description thereof will be omitted.

[0086] Similar to the container with handle 1 of the first embodiment, Figures 6 to 8 The container 100 with a handle shown in the figure comprises: a container body 2, which includes a peripheral wall portion 21 and a bottom wall portion 22 and has a circular opening 23 surrounded by the upper end of the peripheral wall portion 21; a flange portion 3, which is provided at the upper end of the peripheral wall portion 21 and faces outward; and a handle portion 110, which is provided in a manner protruding outward at a portion of the circumference of the flange portion 3. The peripheral wall portion 21 and the bottom wall portion 22 of the container body 2, the flange portion 3, and the handle portion 110 are used Figure 3 The illustrated laminate material 10 is integrally formed.

[0087] The shank 110 curves obliquely upward from the end on the flange 3 side toward the protruding end. The shank 110 is provided with at least one, and in this case, two, reinforcing ribs 111 (reinforcing portions) spaced apart in the width direction of the shank 110 and extending along the longitudinal direction of the shank 110. The reinforcing ribs 111 have a generally U-shaped cross-section and are formed by deforming the shank 110 into a downwardly protruding shape, defining a groove opening upward. One end of the reinforcing rib 111 reaches the protruding end of the shank 110, while the other end is located near the outer peripheral edge of the flange 3.

[0088] The wing portions 112 between the two reinforcing ribs 111 and the two side edges of the handle 110 in the width direction are each bent obliquely upward. The bending angle of the wing portions 112 gradually increases from the end of the handle 110 on the flange portion 3 side toward the protruding end of the handle 110. Furthermore, a protrusion 113 that protrudes outward is integrally provided along a certain length of the wing portions 112 on the protruding end side of the handle 110.

[0089] According to the container with handle 100 of the second embodiment described above, when the handle 110 is held during feeding, Figure 9As shown by the dotted line, positioning the thumb F between the two wing portions 112 on the upper surface of the handle 110, which are bent obliquely upward, and positioning the index and middle fingers (not shown) along the lower surface of the handle 110, improves stability when grasping the handle 110, making feeding easier. Furthermore, the presence of the barrier layer 11 comprising a metal foil in the middle portion of the laminated material 10 in the thickness direction, which forms the handle container 100, facilitates the oblique upward bending of the handle 110 and the oblique upward bending of the wing portions 112 on both side edges of the reinforcing ribs 111, making it difficult for the bent handle 110 and wing portions 112 to return to their original shape.

[0090] Industrial applicability
