Description

[Technical Field]

[0001] The present invention relates to a tube container. [Background technology]

[0002] A tube container is known that has a neck portion with an upper opening that rises from a compressible body portion via a shoulder portion, and a lid body that has a top plate supported above the neck portion and a nozzle portion that rises from the top plate and communicates with the neck portion (Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2023-161985 Summary of the Invention [Problem to be solved by the invention]

[0004] In the container of Patent Document 1, when a large amount of contents remains near the shoulder and the diameter of the nozzle is too small for a finger to fit through, it is impossible to remove the contents without using a tool. Furthermore, it is not necessarily easy to insert a tool through the nozzle from the outside and scrape out the contents near the shoulder.

[0005] An object of the present invention is to provide a tube container from which the contents remaining in the tube container body can be easily removed using a tool attached to the lid body. [Means for solving the problem]

[0006] The first means comprises a tube container body 2 having a compressible body 3 with a shoulder 4 and a neck 8 at the top opening extending therefrom; The container comprises a top plate 14 supported above the neck portion 8, and a lid 10 having a nozzle 20 penetrating the top plate 14 and communicating with the neck portion 8, The lid 10 is detachably attached to the tube container 2 so as to close the neck 8. A removal piece 30 for holding and scraping off the contents accumulated between the other side SF of the nozzle portion 20 and the lower end 25 of one side SB in the radial direction R of the nozzle portion 20 hangs down via a connecting portion 26.

[0007] In this means, as shown in FIG. 1, a nozzle 20 is provided through the top plate of the lid, communicating with the neck of the tube container. A removal piece 30 for holding and scraping off the contents accumulated between the other side SF of the nozzle portion 20 and the lower end 25 of one side SB in the radial direction R of the nozzle portion 20 hangs down via a connecting portion 26. With this structure, even if the diameter of the opening is such that a finger cannot be inserted through the nozzle, the contents remaining near the shoulder when the tube container body 2 is fully squeezed can be easily removed using a tool (removal piece) attached to the lid body.

[0008] The second means includes the first means, and the nozzle portion 20 comprises an upper half-cylinder portion 22 extending from the top plate 14 as a discharge cylinder portion, and a lower half-cylinder portion 24 extending from the top plate as a sealing cylinder portion that is tightly fitted into the neck portion 8, The removal piece 30 hangs down from the lower half-tubular portion 24 through the neck portion 8 to near the inner surface of the shoulder portion 4, and is formed so that it can be pulled up from the neck portion 8 by removing the lid body 10 from the tube container body 2.

[0009] In this means, as shown in FIG. 2(A), the nozzle 20 comprises an upper half 22 standing upright from the top plate 14 as a discharge cylinder, and a lower half 24 hanging down from the top plate as a sealing cylinder that is tightly fitted into the neck 8. The removal piece 30 hangs down from the lower half-tubular portion 24 through the neck portion 8 to near the inner surface of the shoulder portion 4, and is configured so that it can be pulled up from the neck portion 8 by removing the lid body 10 from the tube container body 2. According to this structure, the removal piece 30 is suspended in the neck portion 8 in advance, so the contents can be removed with less effort and simpler procedures than when a separate scraping tool is prepared and inserted into the neck portion 8 after the lid body 10 is opened.

[0010] The third means includes the first means or the second means, and a concave surface portion 32 for storing fluid is formed on the inner surface of the removal piece 30, which is concave outward in the radial direction R when viewed from below.

[0011] In this embodiment, as shown in FIG. 2(C), a recessed portion 32 for storing fluid is formed on the inner surface of the removal piece 30, which is recessed outward in the radial direction R when viewed from below. According to this structure, the concave surface 32 functions as a reservoir for the contents, so that the contents can be stored sufficiently.

[0012] The fourth means includes the first means or the second means, and a protruding edge portion 40 for retaining fluid is provided protruding from the tip 38 of the extraction piece 30 toward the inside in the radial direction R.

[0013] In this embodiment, as shown in FIG. 2(A), a protruding edge 40 for retaining fluid is provided inward in the radial direction R from the tip 38 of the extraction piece 30. According to this structure, the protruding edge 40 exerts a holding force on the contents, so that by opening and lifting the lid body 10 from the tube container body 2, the contents around the shoulder portion 4 (including the inside of the neck portion 8) can be scraped off, making it easy to use.

[0014] The fifth means includes the first means or the second means, and the removal piece 30 is warped outward in the radial direction R from the tip 38 side of the removal piece 30.

[0015] In this means, as shown in FIG. 3(B), the removal piece 30 can bend back from the tip 38 side of the removal piece 30 outward in the radial direction R. With this structure, the holding force for the contents is reduced in the bent state, so that the contents can be easily removed. [Effects of the Invention]

[0016] According to the present invention, the contents remaining in the tube container can be easily removed using the tool attached to the lid. [Brief explanation of the drawings]

[Figure 4] 2 is an explanatory diagram of the operation of the container in FIG. 1, in which (A) shows the stage when the tube container body has been squeezed out completely, and (B) shows the stage when the lid body has been removed from the tube body with the contents still held in the removal piece. BEST MODE FOR CARRYING OUT THE INVENTION

[0018] 1 to 4 show a tube container according to an embodiment of the present invention. This tube container is formed of a tube container body 2 and a lid body 10.

[0019] The tube container body 2 is formed by extending a shoulder portion 4 from a compressible body portion 3 to a neck portion 8 having an open upper end. A shouldered peripheral wall 5 surrounding the neck 8 stands upright from the shoulder 4 . The shouldered peripheral wall 5 has a male thread 6 formed therein. Additionally, a fastening piece 7 is provided on the shoulder 4, positioned outside the shouldered peripheral wall 5, for engaging with a fastening piece 18 of the lid body 12, which will be described later. The fastening piece 7 and the fastening piece 18 form a rotation prevention means d for the lid body 10 relative to the tube container body 2.

[0020] The lid body 10 is a closure device that is removably attached to the tube container body 2 so as to close the upper end opening of the neck portion 8, and has a built-in scraping tool (removal piece 30) that is suspended inside the neck portion 8 in advance. With this configuration, the contents can be removed in a simpler procedure than when the lid body 10 described below is removed from the tube container body 2 and a separately prepared jig is inserted into the lid body 10 or the neck portion 8 of the tube container body 2 to remove the contents. In this embodiment, the lid body 10 consists of a lid main body 12 and an upper lid 50, and a removal piece 30 is connected to a sealing tube portion 24 (described below) attached to the lid body 10 to seal the neck portion 8.

[0021] The lid body 12 has a top plate 14 supported above the neck portion 8, and a nozzle portion 20 that passes through the top plate 14 and communicates with the neck portion 8, and a removal piece 30, which is a jig for scraping the contents, is suspended from the nozzle portion 20 via a connecting portion 26. In this embodiment, the lid body 12 has an outer peripheral wall 16 hanging down from the peripheral edge of the top plate 14 and an inner peripheral wall 17 hanging down from the back surface of the top plate 14 in a double cylindrical shape, and the nozzle portion 20 is arranged at an appropriate position inside this inner peripheral wall 17. The top plate 14 has an annular recess m formed on the outer periphery of its upper surface for engaging the lower end of a circumferential cover wall 54 (described later). The outer peripheral wall 16 is connected to the rear end side of the upper cover 50 via a hinge 48 . For convenience of explanation, the left side of FIG. 1 will be referred to as the "front", the right side as the "rear", and the directions perpendicular to the paper surface as the "left and right". An internal thread 19 for screwing onto the neck portion 8 is formed on the inner surface of the inner peripheral wall 17. However, the method of attaching the top cover 50 to the cover body 12 can be changed as appropriate. In the illustrated example, the outer peripheral wall 16 and the inner peripheral wall 17 are connected by a connecting plate j oriented in the radial direction R, and a fastener 18 for preventing rotation is provided adjacent to the lower end of the inner peripheral wall 17 near this connecting piece j.

[0022] In this embodiment, the nozzle 20 comprises an upper half 22 extending from the top plate 14 as a discharge cylinder, and a lower half 24 extending downward from the top plate as a sealing cylinder that is tightly fitted into the neck 8. However, this structure can be modified as appropriate. In the illustrated example, a small-diameter discharge cylindrical portion 22 is connected to a large-diameter sealing cylindrical portion 24 via a downward step portion 23 . 2(B), the discharge cylindrical portion 22 is eccentric inside the sealing cylindrical portion 24 when viewed from below. In the figure, symbol AL denotes the cylindrical axis of the lower cylindrical portion, and symbol AU denotes the cylindrical axis of the upper half cylindrical portion, the former coinciding with the central axis of the tube container body. However, these arrangements can be changed as appropriate.

[0023] The removal piece 30 hangs down from the lower end surface 25 of one side (rear side in the illustrated example) SB of the nozzle portion 20 in the radial direction R via a connecting portion 26, and is formed so as to be able to hold and scrape off (scrape up) the contents i accumulated between it and the other side (front side in the illustrated example) SF. In this embodiment, as shown in FIG. 1, the inside of the neck portion 8, which is in front of the removal piece 30, and the inside of the nozzle portion 20 form a discharge path L that guides the contents in the tube container body 2 to the outside. The removal piece 30 in the illustrated example is shaped like a tongue piece, and is formed so as to be elastically deformable from the vertical state shown in FIG. 3(A) to the outwardly curved state shown in FIG. 3(B). 2(C), the removal piece 30 has an inner surface F (front surface in the illustrated example) facing the front side portion SF, and this inner surface functions as the action surface F that exerts an adhesive force to the contents i. This adhesive force allows the contents to accumulate between the rear side portion SB and the removal piece 30 and the front side portion SF. In this embodiment, a part of the removal piece 30 (the widthwise intermediate plate portion 31 in the illustrated example) is formed with a concave surface portion 32 that is concave outward in the radial direction R. By providing the concave surface portion 32, the contact area with the contents increases, thereby improving the storage capacity of the contents. The concave surface portion 32 in the illustrated example is formed as a shallow groove extending in the vertical direction of the removal piece 30. A pair of flat plate portions 34 are formed on both sides of the concave surface portion 32, and the outer edges of the pair of flat plate portions 34 are formed into thick edge portions 35. However, these forms can be changed as appropriate.

[0024] In this embodiment, as shown in FIG. 2(A), a protruding edge 40 is provided to protrude downward and inward from the tip 38 of the removal piece 30. The protruding edge portion 40 is a protrusion (burr) from the tip of the removal piece 30, and has the function of adding holding power to the removal piece 30 for the contents, and also has the effect of reducing this holding power by curving the removal piece 30 backward as described below. The inner surface of the protruding edge 40 is an inclined inner surface 44 that slopes from the upper outward to the lower inward. This inclined inner surface serves as a surface (retaining surface 44) that retains the contents stored between the removal piece 30 and the front side portion SF. Reference numeral 42 denotes the outer surface (inclined outer surface) of the protruding edge 40. 3(B), when the removal piece 30 is bent outward in the radial direction R from the tip 38 side (pushed outward), the holding surface 44 changes its orientation toward the vertical direction, reducing the holding force and making it easier to remove the contents. Note that "changing its orientation toward the vertical direction" means that the slope approaches vertical, but it does not need to be completely vertical. In the illustrated example, as shown in FIG. 2(A), a protruding edge 40 that is arc-shaped when viewed from below is attached to the lower end of the concave surface portion 32. As shown in Figure 3(A), the upper end of the intermediate plate portion 31 of the removal piece 30 is formed into a tapered portion t that narrows toward the top. The inner surface of this tapered portion t is a tapered slope 46 that slopes from the top outward to the bottom inward. The remaining portion of the intermediate plate portion 31 is a constant thickness portion u having a uniform thickness in the vertical direction. In this embodiment, the protruding length of the protruding edge portion 40 is designed so that, when viewed from below, the protruding edge portion 40 does not enter within the outline C of the discharge tubular portion 22. This structure makes it possible to prevent the protruding edge portion 40 from interfering with the flow of the contents that are discharged from the body portion 3 through the discharge path L to the outside by the squeezing operation.

[0025] In this embodiment, the connecting portion 26 is formed by a pair of main connecting portions 27 that connect both widthwise sides of the removal piece 30 (thick edge portion 35 in the illustrated example) to the sealing tube portion 24, and a sub-connecting portion 28 formed between these main connecting portions 27. In the preferred illustrated example, the sub-connecting portion 28 is a thin-walled portion, while the main connecting portion 27 is a fulcrum portion that has a relatively strong connecting strength. It is also possible to omit the auxiliary connecting portions 28 and connect the removal piece 30 to the rear side portion SB only by the pair of main connecting portions 27. 3(A), the inner surface p of the cylindrical seal portion 24 and the outer surface q of the intermediate plate portion 31 of the removal piece 30 are formed to be substantially flush in the vertical direction when viewed from the left-right direction. For this reason, the auxiliary connecting portion 28 is arranged to connect the removal piece 30 to the inner edge of the lower end surface 25 of the one side portion SB. These structures can be modified as appropriate.

[0026] The upper lid 50 has a lid peripheral wall 54 extending downward from the peripheral edge of the top plate 52, and the lid peripheral wall 54 is connected to the lid body 12 via the hinge 48. In the illustrated example, a fitting cylindrical portion 56 that fits onto the outer surface of the discharge cylindrical portion 22 and an annular rib 58 that fits onto the inner surface of the discharge cylindrical portion 22 protrude inward from the back side of the top plate 52. Furthermore, a finger hook n is attached to the top plate 52 on the opposite side of the hinge 48 .

[0027] In the above configuration, when the top lid 50 is opened from the state shown in Fig. 1 by placing a finger on the finger loop n and then tilting the tube container body 2 to squeeze the body part 3, the contents in the body part are discharged to the outside through the discharge path L. When the top lid 50 is closed after the discharge operation is completed, the opening surface of the discharge tube part 22 is closed. As shown in Figure 4(A), when only a small amount of content remains, the lid body 10 is rotated and removed from the tube container body 2, and the removal piece 30, which has been previously placed inside the neck portion 8, is pulled upward. At this time, a pulling force z acts on the contents present in the discharge path L, as they are pulled by the operating surface F and the protruding edge 40 of the removal piece 30. Therefore, by rotating and removing the lid 10, the contents can be scraped from the area extending from the inside of the neck 8 to the vicinity of the shoulder 4, as shown in Figure 4(B). In contrast to the conventional example in which a removal tool is prepared separately from the tube container and inserted into the lid body or neck to scrape out the contents, the removal piece 30 of the present invention is already in the neck 8, so there is no need to insert it into the neck. In addition, in this embodiment, the removal piece 30 is pulled up by unscrewing the inner peripheral wall 17 of the lid body 10 from the shouldered peripheral wall 5 of the tube container body 2, so the operation of opening the lid body 10 (by rotating it in the illustrated example) also serves as the operation of scraping out the contents, and there is no need to scrape out the contents separately. After removing the lid 10, as shown in Figure 3(A), the lower opening of the outer wall 16 of the lid body 12 is faced directly downward toward the location (e.g., the user's palm) from which the contents will be removed (not shown), and then, as shown in Figure 3(B), the removal piece 30 is bent back from the tip 38 and pushed outward. This releases the holding force of the protruding edge 40, allowing the contents to fall into the removal location.

[0028] According to the above configuration and function, a removal piece 30 is connected to the lower end surface 25 of one side portion SB of the mouth portion 20 to hold and scrape off the contents accumulated between the other side portion SF of the mouth portion 20, making it easy to remove the contents. The removal piece 30 is installed in a state in which it is placed in advance inside the lower half of the cylindrical mouth portion 20 (cylindrical sealing portion), so that the contents can be easily removed. The inner surface of the removal piece 30 is formed with a concave surface 36 for storing fluid, which is concave outward in the radial direction R when viewed from below, so that the contents can be stored sufficiently. Since a protruding edge 40 for holding fluid is provided inward from the tip 38 of the removal piece 30, the holding power of the contents can be increased, and since the removal piece 30 can be bent outward from the tip 38 side, the holding power of the removal piece 30 (especially the holding power of the protruding edge 40) can be reduced, thereby making it easy to take out the contents.
