Description

Cap of powder container with lifting prevention of pull handle and method for manufacturing same

[0001] The present invention relates to a cap for a powder container that prevents the pull handle from lifting and a method for manufacturing the same.

[0002] A conventional powder container for storing a certain amount of powdered contents such as powdered milk is configured to include a cover part that is connected to the upper side of the powder container and has an opening formed therein, a sealing part that is attached to the upper surface of the cover part to seal the opening, and a pulling part (tab) that is formed by extending from one end of the sealing part but is bent to the other side of the sealing part based on one end of the sealing part so as to overlap the upper surface of the sealing part.

[0003] Meanwhile, in the past, a conveyor belt was used in the process of filling powder into a powder container and assembling and transporting the powder container. However, the pulling part formed by bending and overlapping the upper surface of the sealing part of the powder container was not stably fixed to the upper surface of the sealing part, and during the assembly and transport process, the bent part was lifted or caught on an external device, etc., and was torn and pulled, thereby separating from the sealing part and opening the opening, causing powder inside the powder container to leak out, etc. Problems such as this occurred, and such problems are considered chronic problems among those skilled in the art and recognized as problems that must be solved.

[0004] To address these issues, methods have been introduced that bond the pull-off portion to the upper surface of the sealing portion using adhesives. However, when the adhesive is applied due to the embossing formed on the upper surface of the sealing portion, the adhesive seeps between the embossing, making it difficult to secure a strong fixation between the pull-off portion and the adhesive. Furthermore, when the adhesive solidifies, the height of the contact area of ​​the pull-off portion increases due to the adhesive in addition to the embossing, resulting in a recurrence of the aforementioned problem. Furthermore, even when an adhesive such as double-sided tape is applied between the pull-off portion and the sealing portion, additional processes such as cutting the double-sided tape and removing the protective films on the front and back surfaces are required, resulting in inefficient manufacturing processes and a significant increase in raw material costs. Furthermore, the problem of the height of the contact area of ​​the pull-off portion increasing due to the thickness of the double-sided tape itself remains unresolved.

[0005] The present invention has been proposed to solve the above-described problem, and provides a cap for a powder container with a pull handle that prevents lifting and stably fixes the pull portion without being separated from the sealing portion during the process of filling powder into the powder container and assembling and transporting the powder, and a method for manufacturing the same.

[0006] In addition, the present invention provides a cap for a powder container and a method for manufacturing the same, which prevents the pulling handle from lifting without causing damage to the embossing or the sealing body even when strong pressure is applied to the contact area between the pulling handle and the sealing body.

[0007] In addition, the present invention provides a cap for a powder container with a pull handle that prevents lifting and a method for manufacturing the same, which simplifies the manufacturing process and allows the use of liquid glue, which is a relatively inexpensive raw material, as a configuration for bonding between the pull handle and the sealing body.

[0008] An embodiment includes a body part having an opening formed therein to be coupled to a powder container; and a sealing part formed with a sealing body attached to an upper surface of the body part and covering the opening to seal the opening; a pull handle is formed extending from a point on an outer edge of the sealing body, the pull handle is folded by being bent toward an upper surface of the sealing body to overlap the sealing body, an embossing blank area is formed in a portion of an embossing processing area corresponding to a position of the opening in the sealing body, an adhesive structure is formed in the embossing blank area, and a portion of the pull handle is adhered to the adhesive structure to prevent lifting of the pull handle fixed to the sealing part.

[0009] In another aspect, the adhesive composition may provide a cap for a powder container with a pull handle that is free from lifting, which is a liquid glue or a double-sided adhesive tape.

[0010] In another aspect, the pull handle may be composed of first to third parts formed integrally with each other, the first part being integrally connected to the sealed body, a second part positioned between the first and third parts having a hook hole formed therein, and at least a portion of the lower surface of the third part facing the embossed blank area, thereby providing a cap for a powder container that prevents the pull handle from lifting when attached to the adhesive configuration.

[0011] In another aspect, a cap of a powder container can be provided in which the lifting of the pull handle in which the embossing is formed is prevented in the embossing treatment area excluding the embossing blank area.

[0012] In another aspect, a method for manufacturing a cap for a powder container with a pull handle of the fourth clause prevented from lifting may be provided, the method including the steps of: cutting a sheet to provide the body part and the sealing part; attaching the body part and the sealing part; applying an adhesive composition to the embossing blank area; performing an embossing process on the embossing area using a mold; and attaching the pull handle to the sealing body by bending the pull handle.

[0013] In another aspect, the step of performing embossing on the embossing processing area may provide a method for manufacturing a cap of a powder container with lifting prevention, the method including the steps of preparing a main mold and an insert mold, installing the main mold on a mold holder, inserting the insert mold into an insert insertion hole of the main mold and installing it on the mold holder, and performing embossing on the embossing processing area using the mold.

[0014] In another aspect, the insert mold is divided into first to third mold regions, and an embossing for preventing a gap is formed in the first and second mold regions except for the third mold region between the first and second mold regions, and the first and second mold regions have a step with respect to the third mold region, thereby providing a method for manufacturing a cap for a powder container that prevents lifting.

[0015] In another aspect, when embossing is performed in the embossing treatment area, the third mold area can provide a method for manufacturing a cap of a powder container that is prevented from lifting by facing the embossing blank area.

[0016] The present invention provides a cap for a powder container and a method for manufacturing the same, which prevents the pulling handle from lifting and stably fixes the pulling part without it coming off from the sealing part during the process of filling powder into the powder container and assembling and transporting the powder.

[0017] The embodiment provides a cap for a powder container and a method for manufacturing the same, which prevents lifting of a pull handle without damage to the embossing or sealing body even when strong pressure is applied to the contact area between the pull handle and the sealing body.

[0018] The embodiment creates an embossing blank area on a sealed body by changing the shape of a mold to enable application of an adhesive composition, and prevents the phenomenon of embossing becoming empty in a space where embossing should be formed around the embossing blank area.

[0019] The present invention provides a cap for a powder container with a pull handle that prevents lifting and a method for manufacturing the same, which simplifies the manufacturing process and allows the use of a liquid glue, which is relatively inexpensive in raw materials, as a configuration for bonding between the pull handle and the sealing body.

[0033] The present invention is capable of various modifications and embodiments. Therefore, specific embodiments are illustrated in the drawings and described in detail in the detailed description. The effects and features of the present invention, as well as the methods for achieving them, will become clear with reference to the embodiments described in detail below together with the drawings. However, the present invention is not limited to the embodiments disclosed below and can be implemented in various forms. In the following embodiments, the terms "first," "second," etc. are not used in a limiting sense but are used for the purpose of distinguishing one component from another. Furthermore, the singular expression includes the plural expression unless the context clearly indicates otherwise. Furthermore, terms such as "include" or "have" indicate the presence of a feature or component described in the specification, and do not preemptively exclude the possibility that one or more other features or components may be added. Furthermore, in the drawings, the sizes of components may be exaggerated or reduced for convenience of explanation. For example, the size and thickness of each component shown in the drawings are arbitrarily shown for convenience of explanation, and thus the present invention is not necessarily limited to what is shown.

[0034] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings. When describing with reference to the drawings, identical or corresponding components are given the same reference numerals and redundant descriptions thereof will be omitted.

[0035] Fig. 1 is a perspective view of a cap of a powder container with a pull handle prevented from lifting according to an embodiment of the present invention, and Fig. 2 illustrates a state in which the pull handle is opened in the cap of the powder container with the pull handle prevented from lifting. In addition, Figs. 3 and 4 schematically illustrate a body part constituting a cap of a powder container with a pull handle prevented from lifting, and Fig. 5 schematically illustrates a sealing part constituting a cap of a powder container with a pull handle prevented from lifting. In addition, Fig. 6 is a bottom view of a cap of a powder container with a pull handle prevented from lifting according to an embodiment of the present invention.

[0036] Referring to FIGS. 1 and 2, the cap (10) of the powder container with the pull handle prevented from lifting is made of aluminum, but is not limited thereto, as it is considered a sanitary, food-compatible material that is difficult for substances to stick to and easy to clean, and is an environmentally friendly and safe packaging solution that is recyclable.

[0037] Since powdered milk may deteriorate when exposed to moisture and oxygen in the air, the powder container cap (10) completely seals the powder container, thereby helping to preserve the freshness and nutritional value of the baby formula. Furthermore, the powder container cap (10) can prevent unauthorized access to the interior of the powder container and provide a non-slip function. Furthermore, the powder container cap (10) is highly durable, can protect the powdered milk container, and can protect the product from physical damage during transportation and storage.

[0038] The cap (10) of the powder container may include a body portion (100) and a sealing portion (200).

[0039] The cap (10) of the powder container can be coupled to the powder container (not shown), for example, to the upper side of the powder container. In addition, the sealing portion (200) is attached to the upper surface of the body portion (100) and covers the opening portion (100h) to seal the opening portion (100h). In addition, a pull handle (210) is formed extending from a point on the outer edge of the sealing portion (200).

[0040] Referring to FIGS. 3 and 4, an opening (100h) is formed inside the body portion (100).

[0041] The central region of the body portion (100) may be cut into a circle, and a portion of the circle may be cut so as to be a horizontal line, thereby forming the illustrated opening (100h). That is, the inner edge of the body portion (100) has a round inner edge and a straight inner edge. The round inner edge may have a shape that matches an imaginary circle that passes through both ends of the straight line. In addition, the pull handle (210) is located on one side of the body portion (100), and the straight inner edge is located on the other side of the body portion (100).

[0042] More specifically, the X-axis and the Y-axis are defined as virtual horizontal axis passing through the virtual center point (cp) of the body part (100). Here, the Y-axis passes through the center point of the straight line. In addition, the opening (100h) can be defined as an area surrounded by a boundary line (BL), which is the end of the inner edge of the body part (100). In the Y-axis, which is the vertical axis, the intersection of the positive Y-axis and the boundary line (BL) is defined as point a, in the Y-axis, which is the vertical axis, the intersection of the negative Y-axis and the boundary line (BL) is defined as point d, and in the X-axis, which is the horizontal axis, the intersection of the negative X-axis and the boundary line (BL) is defined as point b. Here, point d is the center point of the straight line. In the area of ​​the opening (100h), the distance from the center point (cp) of the body part (100) to point a and the distance from the virtual center point (cp) to point b may be the same. And, the distance from point a to point b to the boundary line (BL) and the center point (cp) may be the same. And, the virtual line segment from the center point (cp) of the body part (100) to point a and the virtual line segment from the center point (cp) to point b may form a right angle with each other. And, the distance from the center point (cp) of the body part (100) to point a or the distance from the center point (cp) to point b may be the radius, and a virtual fan-shaped area may be defined in which the line extending from point a to point b among the boundary lines (BL) is the arc. And, this virtual fan-shaped area may be the first area (R1) constituting the opening (100h).

[0043] In addition, if an imaginary inclined line (dc) passing through the center point (cp) is defined at a negative angle from the negative X-axis, the inclined line (dc) constitutes an imaginary point c, which is an intersection with the boundary line (BL), and point c is located at the lower left of the body part (100) on the drawing. Then, a virtual fan-shaped area can be defined, with the distance from the center point (cp) of the body part (100) to point b or the distance from the center point (cp) to point c as a radius, and a line extending from point b to point c among the boundary lines (BL) as an arc. Then, this imaginary fan-shaped area can become a second area (R2) constituting the opening (100h). Then, an imaginary triangle can be defined, with the center point (cp) and point c as the hypotenuse, the center point (cp) to point d as the height, and the point c to point d as the base. And, this virtual area of ​​the triangle can be the third area (R3) constituting the opening (100h). In addition, the line near point c among the boundary lines (BL) can be a round line. And, based on the Y-axis, the first to third areas (R1, R2, R3) and the virtual fourth area (R4) having a symmetrical shape can be defined. And, the opening (100h) is composed of the first to fourth areas (R1, R2, R3, R4).

[0044] A virtual attachment line (AL) indicated by a solid line is depicted on the upper surface of the body portion (100). The attachment line (AL) surrounds the boundary line (BL) and may be a circular line. An attachment area (AR) is defined between the boundary line (BL) and the attachment line (AL). When the sealing portion (200) is attached to the body portion (100) as shown in Fig. 1, the lower edge area of ​​the sealing portion (200) is attached to the attachment area (AR) and may cover the opening (100h).

[0045] Referring to FIGS. 2, 5, and 6, the sealing portion (200) may have a circular shape, but is not limited thereto. The total area of ​​the sealing portion (200) may be substantially the same as the area surrounded by the attachment line (AL) of FIG. 4.

[0046] The sealing member (200) is attached to the upper surface of the body part (100) and covers the opening (100h) to seal the opening (100h). An adhesive may be applied to the upper surface of the body part (100) along the edge of the opening (100h) so that the sealing member (200) may be attached to the upper surface of the body part (100). However, other attachment materials other than the adhesive may also be used, and the sealing member (200) may be attached by a heat-fusion method. That is, the lower surface of the edge portion of the sealing member (200) may be attached to the periphery of the opening (100h) among the body part (100). More specifically, the edge area of ​​the lower surface of the sealing member (200) may be attached on the attachment area (AR) of the body part (100). Therefore, the total area of ​​the sealing member (200) has an area that is larger than the total area of ​​the opening (100h) by the attachment area (AR).

[0047] In addition, the sealing portion (200) can be divided into a sealing body (200b) and a pull handle (210). The pull handle (210) can be formed to extend from a point on the outer edge of the sealing body (200b) toward the central region of the sealing body (200b). In addition, the pull handle (210) can be folded and bent toward the central region of the upper surface of the sealing body (200b) so as to overlap with the sealing body (200b). In other words, the pull handle (210) can be formed integrally with the sealing body (200b). In addition, according to an embodiment, it can be formed of an aluminum sheet like the sealing body (200b), but is not limited thereto. In addition, both corners of the ends of the pull handle (210) can be rounded, but are not limited thereto. Additionally, a hanging hole (210h) may be formed in one area of ​​the pull handle (210).

[0048] An embossed embossing area (220) is formed in a portion of the sealed body (200b). By embossing the sealed body (200b), the problem of at least a portion of the sealed body (200b) shrinking and expanding and becoming crumpled during the process of filling and distributing powdered milk in a powder container, which is a problem of damaging the appearance, i.e., deformation of at least a portion of the sealed body (200b). When the sealed portion (200) is attached to the body portion (100), the portion of the sealed body (200b) facing the opening (100h) of the body portion (100) can become the embossing area (220). Therefore, the embossing area (220) matches the shape of the opening (100h).

[0049] An embossing blank area (220n) exists in some areas of the embossing area (220). The embossing area (220) may also be defined as an area excluding the embossing blank area (220n).

[0050] Fig. 7 is a top view of a pull handle as a component of a sealing part. Fig. 8 is a schematic cross-section of a cap of a powder container cut along the line C1-C2 of Fig. 1, and Fig. 9 is a schematic enlarged view of a portion of Fig. 8.

[0051] Referring to FIG. 5 and FIG. 7 to FIG. 9, the pull handle (210) is bent to overlap the sealing body (200b) based on the boundary line (210c) between the pull handle (210) and the sealing body (200b), and the surface of the pull handle (210) forms approximately the same plane as the surface of the sealing body (200b). The pull handle (210) can be divided into first to third regions (x1, x2, x3) in a direction perpendicular to the boundary line (210c).

[0052] The second region (x2) is defined as the region located between the first and third regions (x1, x3).

[0053] The third width of the third region (x3) in the direction perpendicular to the boundary line (210c) is formed to be smaller than the first width of the first region (x1) in the direction perpendicular to the boundary line (210c), and the second width of the second region (x2) in the direction perpendicular to the boundary line (210c) is formed to be larger than the first and third widths of the first and third regions (x1, x3), respectively.

[0054] A hanging hole (210h) is formed in a part of the second region (x2). The hanging hole (210h) is positioned so as to pass through the boundary between the first and second regions (x1, x2) and the boundary between the second and third regions (x2, x3). Therefore, the second width and length of the second region (x2) in the direction perpendicular to the boundary line (210c) may be equal to the length of the diameter of the hanging hole (210h).

[0055] The third region (x3) may have a round shape to correspond to the shape of the hanging hole (210h), and the second region (x2) and the third region (x3) may have round shapes to correspond to the shape of the hanging hole (210h).

[0056] When the pull handle (210) is folded toward the sealed body (200b), the first and third regions (x1, x3) overlap with the sealed body (200b).

[0057] The first region (x1) can be defined as the first part (201) of the pull handle (210), the second region (x2) as the second part (202), and the third region (x3) as the third part (203). The first to third parts (201, 202, 203) are formed integrally to form one pull handle (210).

[0058] When the pull handle (210) is folded toward the sealed body (200b), a part of the third region (x3) may face the embossed blank region (220n). That is, a part of the third section (203) may face the embossed blank region (220n).

[0059] An adhesive composition (20) may be applied to the embossed blank area (220n). The adhesive composition (20) may be liquid glue. By the adhesive composition (20) applied to the embossed blank area (220n), a portion of the third section (203) may be attached to the embossed blank area (220n), and the pull handle (210) may be fixedly attached to the sealing body (200b).

[0060] In various embodiments, the adhesive composition (20) may be a double-sided adhesive tape. For example, the adhesive composition (20) may be composed of a thermally fused urethane adhesive that functions like a double-sided adhesive tape using heat.

[0061] Fig. 10 is a flow chart of a method for manufacturing a cap of a powder container with a pull handle that prevents lifting according to an embodiment of the present invention. Furthermore, Fig. 11 illustrates a main mold and an insert mold, Fig. 12 illustrates the installation of the main mold and the insert mold on a mold holder, and Fig. 13 is a flow chart of a step of performing embossing processing on an embossing processing area. Furthermore, Fig. 14 illustrates the corresponding relationship between an insert mold and a portion of a powder container cap.

[0062] Referring to FIGS. 1 to 10, a method for manufacturing a cap of a powder container with a pull handle that is prevented from lifting (S100) may include a step of cutting a sheet to prepare a body part and a sealing part (S110), a step of attaching the body part and the sealing part (S120), a step of applying an adhesive composition to an embossing blank area of ​​a sealing body (S130), a step of performing embossing on an embossing area (S140), a step of attaching the pull handle to the sealing body by bending the pull handle (S150), and a step of inspecting the state of the powder container cap (S160).

[0063] A powder container cap manufacturing system may be provided for manufacturing a powder container cap that prevents lifting of a pull handle. The powder container cap manufacturing system may include a sheet cutting device, a product transport device for transporting powder container caps to each process device, a mold device, and an inspection device.

[0064] - Step of cutting the sheet to prepare the body and sealing part (S110)

[0065] A body part (100) and a sealing part (200) can be prepared by cutting a raw material sheet to a predetermined standard. The sealing part (200) can be prepared by forming a sealing body (200b) and a pull handle (210) as one piece.

[0066] - Step of attaching the body and sealing part (S120)

[0067] By attaching a sealing body (200b) to the attachment area (AR) of the body part (100), the opening (100h) of the body part (100) can be covered with the sealing body (200b).

[0068] - Step of applying adhesive composition to embossed blank area of ​​sealed body (S130)

[0069] An adhesive composition (20), which is a liquid glue, is applied to the embossing blank area (220n) of the sealed body (200b).

[0070] In various embodiments, an adhesive composition (20) as a double-sided adhesive tape may be attached to the embossed blank area (220n) of the sealing body (200b).

[0071] When the pull handle (210) is attached to the sealing body (200b) in the process described later and the adhesive composition (20) is solidified, the height of the adhesive composition (20) can be determined in consideration of the height of the embossing formed in the process described later, and the amount of the adhesive composition (20) can be determined. When the pull handle (210) is attached to the sealing body (200b), the amount of the adhesive composition (20) applied to the embossing blank area (220n) can be determined so that the surface of the sealing body (200b) and the surface of the pull handle (210) can be substantially flush with each other.

[0072] In various embodiments, when an adhesive composition (20) as a double-sided adhesive tape is attached to an embossing blank area (220n), the height of the adhesive composition (20) after the pull handle (210) is attached on the sealing body (200b) can be determined by considering the height of the embossing formed in the process described later.

[0073] - Step of performing embossing in the embossing processing area (S140)

[0074] Referring further to FIGS. 11 to 14, the step (S140) of performing embossing processing on the embossing processing area (220) may include a step (S141) of preparing a main mold and an insert mold, a step (S142) of installing the main mold on a mold holder, a step (S143) of inserting the insert mold into the insert insertion hole of the main mold, and a step (S144) of performing embossing processing on the embossing processing area (220) of the sealed body (200b).

[0075] 1) Step of preparing the main mold and insert mold (S141)

[0076] The mold (300) includes a main mold (310) and an insert mold (400).

[0077] The main mold (310) may have a shape corresponding to the sealed body (200b). In addition, an embossing treatment portion (320) is formed on the main mold (310). With the main mold (310) and the sealed body (200) facing each other, the embossing treatment portion (320) is formed in an area corresponding to the embossing treatment area (220) of the sealed body (200b).

[0078] An insertion hole (300h) is formed in some areas of the embossing processing section (320).

[0079] The insert mold (400) is composed of first to third mold regions (410, 420, 430).

[0080] The first mold area (410) is formed as a straight-line mold area on the inner and outer sides, and a first gap-prevention embossing is formed. In addition, the inner side of the second mold area (420) is formed as a round-type mold area, and a second gap-prevention embossing is formed. In addition, the third mold area (430) is defined as a mold embossing gap area, and thus no embossing is formed.

[0081] The third mold region (430) has a sunken shape, so that the first and second mold regions (410, 420) and the third mold region (430) have a step difference from each other. The first and second mold regions (410, 420) have the same height, and the third mold region (430) has a lower height than the first and second mold regions (410, 420).

[0082] It is assumed that when the insert mold (400) is inserted into the insert insertion hole (300h), embossing is formed on the sealing portion (200) using the mold (300).

[0083] The positional relationship of the first to third mold regions (410, 420, 430) is described assuming that the pull handle (210) is bent and attached to the adhesive configuration (20).

[0084] The position at which the first mold area (410) is defined is the position where the inner surface of the first mold area (410) faces the end of the pull handle (210). In addition, the position at which the second mold area (420) is defined is the position corresponding to the hanging hole (210h). In addition, the third mold area (430) corresponds to the area where the third part (203) of the pull handle (210) is located, and the third mold area (430) corresponds to the embossing blank area (220n).

[0085] In various embodiments, the first partial mold constituting the first mold region (410) and the second partial mold constituting the second mold region (420) may be formed integrally with the main mold (310). In various embodiments, the first to third partial molds constituting the first to third mold regions (410, 420, 430) may be formed integrally with the main mold (310).
