Description

[Technical field]

[0001] The present invention relates to a pair of containers having an inner container and a frame body made of plastic, and to the inner container and frame body that constitute the pair of containers. [Background technology]

[0002] Among packaging containers, there are paired containers consisting of two parts, with an inner container inside an outer container. In the first embodiment of this paired container, the inner container is used as a refill container, the main purpose of which is to contain the contents, and is manufactured on the premise of replacement, while the outer container is used as a stand for the inner container, making it reusable and thus saving container parts. A second type of container is a pair of containers with a double structure in which the inner container is not replaceable, but has a rounded bottom to improve the design of the container and to enable removal of the contents without leaving any residue, and the outer container is transparent so that the inner container can be seen, and is molded as a single unit.

[0003] An example of the former technology is JP 2019-51981 A (Patent Document 1), and an example of the latter technology is JP 4911401 A (Patent Document 2). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2019-51981 A [Patent Document 2] Patent No. 4911401 Summary of the Invention [Problem to be solved by the invention]

[0005] The first type of paired container was based on the premise that the inner container would be replaced, and the overall design of the inner and outer containers was poor, with the inner container being exclusively for replacement and the outer container being a stand for the inner container, which established an established image and function. On the other hand, the second type of paired container had the characteristic that the shape of the inner container was visible, but the inner and outer containers were connected and could not be separated, and it represented one design aspect of a single container.

[0006] One aspect of the present disclosure is to provide a pair of containers, or an inner container or frame that constitutes the pair, which may or may not be a refill container and which have excellent integrity between the inner container and the frame while allowing the inner container to be removed from the frame serving as a stand. An object of one embodiment of the present disclosure is to provide a paired container that can be regarded as a single container rather than a paired container at first glance, or an inner container or frame that constitutes the paired container. An object of one embodiment of the present disclosure is to provide a paired container having a highly safe attachment portion of the inner container when the inner container is attached to the frame, or an inner container or frame that constitutes the paired container. An object of one embodiment of the present disclosure is to provide a pair of containers with excellent design, or an inner container or a frame that constitutes the pair of containers.

[0007] Note that the description of these problems does not preclude the existence of other problems. In addition, one embodiment of the present disclosure does not necessarily solve all of these problems. Furthermore, problems other than these can be extracted from the description of the specification, drawings, and claims. [Means for solving the problem]

[0008] One aspect of the present disclosure provides a pair of containers having an inner container, a frame, and a nozzle for dispensing the contents of the inner container, the inner container being detachable from the frame, the frame having an attachment recess to which the inner container is attached and detachable, a reinforcing protrusion protruding from the attachment recess, and a bottom portion which can be placed on a flat surface, the frame being made of a rigid material capable of supporting the inner container, the inner container having a camouflage portion which complements the recess of the attachment recess when the inner container is attached to the attachment recess, and a neck portion which can be fitted into the attachment recess and to which the nozzle is attached, the connection between the inner container, frame, and nozzle can be strengthened by tightening the reinforcing protrusion together with the neck portion of the inner container with the screw cap of the nozzle.

[0009] One aspect of the present disclosure is a pair of containers having an inner container, a frame, and a nozzle for discharging the contents of the inner container, the inner container being detachable from the frame, the frame having an attachment recess for attaching and detaching the inner container, a reinforcing protrusion protruding from the attachment recess, and a bottom portion that can be placed on a flat surface, the frame being made of a rigid material capable of supporting the inner container, the inner container having a camouflage portion that complements the recess of the attachment recess when attached to the attachment recess, and a neck portion that can be fitted into the attachment recess and to which the nozzle is attached, the pair of containers being capable of reinforcing the connection between the inner container, the frame, and the nozzle by tightening the reinforcing protrusion together with the neck portion of the inner container with the screw cap of the nozzle. In addition, the reinforcing protrusion can strengthen the connection between the inner container and the frame, and can prevent the inner container from being easily detached from the frame during use. Therefore, the pair of containers is easy to use despite being a pair of containers.

[0010] One aspect of the present disclosure provides a pair of containers having an inner container and a frame body, with the inner container being detachable from the frame body, the frame body having an attachment recess into which the inner container can be attached and detached, and the inner container having a camouflage portion that complements the recess of the attachment recess when attached to the inner container. One aspect of the present disclosure is a paired container having an inner container and a frame body, with the inner container being detachable from the frame body, wherein the frame body has an attachment recess into which the inner container can be attached and detached, and the inner container has a camouflage part that complements the recess of the attachment recess when attached to the attachment recess.Therefore, when the inner container is attached to the frame body, the attachment recess formed on the frame body is complemented by the camouflage part formed on the inner container, so it can be visually recognized as if there is no attachment recess, and the paired container has excellent integrity between the inner container and the frame body.

[0011] One aspect of the present disclosure provides a pair of containers, in which the camouflage portion extends from the neck of the inner container toward the opening of the mounting recess, and its ends are formed in a shape that smoothly continues the outer frame lines of the frame bodies on both sides of the camouflage portion. One aspect of the present disclosure is a paired container in which the camouflage portion extends from the neck of the inner container toward the opening of the mounting recess, and its ends are formed in a shape that smoothly continues the outer frame lines of the frame body on both sides that sandwich the camouflage portion.Therefore, even if the outer frame line of the frame body is cut out due to the formation of the mounting recess, the camouflage portion fills in the cut-out portion, and the outer frame line of the frame body can be visually perceived as being continuous, resulting in a paired container with excellent integrity between the inner container and the frame body.

[0012] One aspect of the present disclosure provides a pair of containers in which a frame has a support portion for supporting an inner container, and the camouflage portion has an attachment portion having an engagement portion with the support portion. In one aspect of the present disclosure, a pair of containers is provided in which a frame has a support portion for supporting an inner container, and the camouflage portion has an attachment portion having an engagement portion for the support portion, and since the camouflage portion has an engagement portion that extends beyond the neck portion and is longer than the diameter of the neck portion, a larger engagement area can be secured than when only the portion corresponding to the neck portion is engaged with the frame, thereby making it possible to more reliably support the inner container.

[0013] One aspect of the present disclosure provides a pair of containers, in which the support portion of the frame body is formed as a protrusion protruding from a wall surface of the frame body, and the engagement portion of the inner container is formed as a groove on the wall surface of the mounting portion. In one aspect of the present disclosure, the support portion of the frame is formed in a protruding piece shape protruding from the wall surface of the frame, and the engagement portion of the inner container is formed in a groove shape from the wall surface of the mounting portion, so that the engagement structure or support structure of the inner container and the frame is a structure in which the protruding piece part of the frame is fitted into the groove part of the inner container. With such a structure, the inner container can be firmly engaged with the frame, and the support performance of supporting the inner container can be improved. In addition, the frame, which is not replaced compared to the inner container, is generally considered to have a longer life than the inner container, but by forming the support portion of the frame in a protruding piece shape, dirt is less likely to adhere to the frame than when it is formed in a groove shape, and even if dirt does adhere, it is easier to remove it. Therefore, it is easy to keep the frame, which is prone to accumulate dirt with long-term use, clean.

[0014] One aspect of the present disclosure provides an inner container used in a pair of containers in which the inner container is detachable from a frame body, the inner container having a mounting recess that, when the inner container is attached to a frame body having a mounting recess to which the inner container is detached, a disguised portion that complements the recess of the mounting recess, and a neck portion that can be fitted into the mounting recess and to which a nozzle is attached. One aspect of the present disclosure is an inner container used in a pair of containers where the inner container is detachable from a frame body, wherein when the inner container is attached to a frame body having an attachment recess to which the inner container is detached, the inner container has a camouflage portion that complements the recess of the attachment recess, and a neck portion that can fit into the attachment recess and to which a nozzle is attached.Therefore, when the inner container is attached to the frame body, the attachment recess formed on the frame body is complemented by the camouflage portion formed on the inner container, so that it can be visually recognized as if there is no attachment recess, resulting in a pair of containers with excellent integrity between the inner container and the frame body.

[0015] One aspect of the present disclosure is a frame used in a pair of containers in which an inner container is detachable from the frame, To provide a frame having an attachment recess for attaching and detaching an inner container and a bottom portion that can be placed on a flat surface, made of a rigid material capable of supporting the inner container, the attachment recess having a reinforcing protrusion protruding upward from the wall surface of the central portion, the frame being capable of reinforcing the joining state of the inner container, the frame, and the nozzle by tightening the reinforcing protrusion together with the neck portion of the inner container with a screw cap of a nozzle that discharges the contents in the inner container.

[0016] One aspect of the present disclosure is a frame used in a pair of containers in which an inner container is detachable from the frame, The frame has an attachment recess into which the inner container is attached and detached, and a bottom that can be placed on a flat surface, is made of a rigid material capable of supporting the inner container, and the attachment recess has a reinforcing protrusion protruding upward from the wall surface at the center thereof, and the frame is capable of reinforcing the connection between the inner container, frame, and nozzle by tightening the reinforcing protrusion together with the neck of the inner container with the screw cap of the nozzle that dispenses the contents inside the inner container, so that the connection between the inner container and the frame can be strengthened by the reinforcing protrusion, and the inner container can be prevented from easily coming off the frame during use.As a result, the paired container is easy to use despite being a paired container. Effect of the Invention

[0017] One aspect of the present disclosure is a paired container, which may or may not be a refill container, and which has excellent integrity between the inner container and the frame body while allowing the inner container to be removed from the frame body, or the inner container or frame body that constitutes the paired container. One aspect of the present disclosure is a paired container that may at first glance be considered as a single container rather than a paired container, or an inner container or frame that constitutes the paired container. One aspect of the present disclosure is a pair of containers that has a high safety at the attachment portion of the inner container when the inner container is attached to a frame, or an inner container or frame that constitutes the pair of containers. One aspect of the present disclosure is a pair of containers with excellent design, or an inner container or frame that constitutes the pair of containers. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] The paired containers of the present disclosure will be described in more detail based on the embodiments. Fig. 1 is a perspective view showing a paired container 1 made of a plastic container in use, Fig. 2 is a front view thereof, Fig. 3 is a left side view thereof, and Fig. 4 is a plan view thereof. The paired container 1 shown in these figures is composed of a roughly egg-shaped inner container 10 and a frame body 20 shaped like a roughly elliptical ring with a certain depth, standing on its depth side. The inner container 10 is housed inside the frame body 20 and is used with a nozzle (dispenser) 2 attached to the inner container 10.

[0020] The paired container 1 may be understood as comprising at least an inner container 10 and a frame 20, and may also be understood as comprising these with a nozzle 2. This paired container 1 is used as a packaging container with shampoo, conditioner, etc. packed in the inner container 10. Next, each part constituting the pair container 1 will be described.

[0021] <Frame 20>: First, a description will be given of the frame 20. Fig. 5 is a perspective view of the frame 20, and Fig. 6 is a plan view of the frame 20. The frame 20 has the function of supporting the inner container 10, which will be described later and cannot stand up by itself, and is disposed so as to partially cover the outside of the inner container 10. The shape of the frame 20 shown in Figures 5 and 6 is one embodiment, and as long as it has a part for supporting the inner container 10 and a bottom 25 that can be placed on a shampoo shelf or the like, there is a high degree of freedom in the shape and design of the other parts, and the frame 20 can be formed into any shape with excellent design.

[0022] A generally U-shaped mounting recess 22 into which the neck 11 of the inner container 10 is inserted is formed in the top 21 of the frame 20. A support portion 23 that engages with the inner container 10 and supports the inner container 10 is formed on the outer periphery of this mounting recess 22. To explain the shape of the support portion 23 more specifically, a protrusion protruding outward from the wall surface 22a of the mounting recess 22 is formed along the wall surface 22a of the mounting recess 22, and the groove portion 14b of the inner container 10 fits into this support portion 23, thereby supporting the inner container 10.

[0023] Furthermore, a reinforcing protrusion 24 capable of strengthening the connection between the inner container 10 and the frame 20 is formed at the central position 22b of the U-shape of the mounting recess 22. This reinforcing protrusion 24 protrudes upward from the wall surface at the central part of the mounting recess 22. After the inner container 10 is fitted into the frame 20, when the nozzle 2 is attached to the neck 11 of the inner container 10, the screw cap 2b of the nozzle 2 (see Figs. 1 and 2) engages with the reinforcing protrusion 24 together with the neck 11 of the inner container 10, thereby fixing the nozzle 2 to the inner container 10 and the frame 20 at the same time.

[0024] The reinforcing projection 24 having such a function can have a shape having a portion protruding upward from the wall surface of the mounting recess 22, or a portion protruding further outward from the upward protruding portion. In the former case, the upward protruding portion can be held down by the screw cap 2b of the nozzle 2, and in the latter case, the portion protruding outward can be sandwiched between the threads of the screw cap 2b.

[0025] A bottom 25 is formed at the lower part of the frame 20, and a flat surface is formed on which the pair container 1 can be placed on a shampoo stand or shelf.

[0026] The shape of the frame 20 has been described as being like a roughly oval ring with depth that is stood upright on its depth side, but as shown in Fig. 3, the frame 20 is shaped so that its middle part 26 gradually becomes thinner than its top 21 and bottom 25 when viewed from the side, and is designed so that the egg-shaped roundness of the inner container 10 is not hidden but is more clearly visible when viewed from the side. Also, as shown in Fig. 2, when the frame 20 is viewed from the front, it is shaped so as to enclose the outside of the egg-shaped inner container 10 with a specified gap between them, and is designed so as to reveal the suspended form of the inner container 10.

[0027] The material of the frame 20 is preferably a hard resin such as polycarbonate, PET, polystyrene, polyethylene, or polypropylene, because it is easy to mold, lightweight, and has a hardness that allows the shape of the inner container 10 containing the contents to be maintained. However, the material of the frame 20 is not limited to these resins, and other materials such as metal and ceramic may also be used.

[0028] <Inner container 10>: Next, the inner container 10 will be described. Fig. 7 is a perspective view of the inner container 10, and Fig. 8 is a plan view of the inner container 10.

[0029] The inner container 10 is a part that serves to contain the contents such as shampoo, and is a part that forms the paired container 1 together with the frame 20. Since the inner container 10 can be freely detached from the frame 20, it can be replaced with another inner container 10 filled with the contents once the contents are consumed. In that sense, it may be a refill container. Alternatively, regardless of whether the contents are consumed or not, it can be used in an appropriate way, such as by replacing the inner container with one of a different design, or by replacing the inner container containing shampoo with one containing conditioner, etc.

[0030] The main body 12 of the inner container 10 shown in Figures 7 and 8 is egg-shaped, which is innovative and has an excellent design, and is also highly practical because the contents decrease during use and tend to accumulate at the bottom of the main body 12, but the remaining contents can be sucked up by the nozzle 2. The neck 11 of the inner container 10 is a connecting portion with the nozzle 2, and is formed with a screw thread 11a for fastening the nozzle 2. In addition, an attachment portion 13 is formed at the base of the neck 11, i.e., near the boundary with the main body 12.

[0031] The mounting part 13 is a joining portion for attaching the inner container 10 to the frame body 20. The shape of the mounting part 13 is not particularly limited, but the mounting part 13 has a shape that conforms to the mounting recess 22 of the frame body 20, and the mounting part 13 shown in Fig. 8 is formed into a substantially rectangular shape in a plan view. The mounting portion 13 has a groove portion 13b which engages with the support portion 23 of the frame body 20 to support the inner container 10 on the frame body 20. The inner container 10 is assembled into the frame body 20 by fitting the support portion 23 of the frame body 20 into this groove portion 13b.

[0032] The camouflage part 14 is a portion that fills the cut-out portion of the mounting recess 22 when the inner container 10 is fitted into the mounting recess 22 of the frame body 20. In other words, referring to Fig. 5 and Fig. 1, the outer frame line 27 that forms a smooth curve at the top 21 of the frame body 20 is complemented by the outer frame line 14a of the camouflage part 14, and the camouflage part 14 is formed so as to ensure the continuity of the outer shape by making it appear as if the smooth curve is maintained.

[0033] Since the inner container 10 and the frame 20 can be handled and traded separately, the corners of the mounting recess 22 and the camouflage part 14 are chamfered to a minimum extent to prevent danger. Therefore, as long as no sharp corners are created, the continuity of the container's outer shape may be lost, and when the container is viewed as a whole, the camouflage part 14 complements the cutout part caused by the mounting recess 22 to form the continuity of the container's outer shape.

[0034] In addition, in Figure 7, the groove portion that serves as the engagement portion for engaging with the support portion 23 of the frame body 20 is not only groove portion 13b located within the width of the neck portion 11, but also groove portion 14b that is connected to groove portion 13b is provided in the camouflage portion 14 that protrudes beyond the width of the neck portion 11. Therefore, it can be said that groove portion 13b is extended by the length of groove portion 14b provided in camouflage portion 14, and as a result, the area engaging with support portion 23 of frame body 20 is increased compared to when frame body 20 engages only around neck portion 11, so that inner container 10 can be more stably supported by frame body 20.

[0035] By providing such a camouflage part 14, when the inner container 10 is fitted into the frame body 20, the recessed portion of the mounting recess 22 is filled with the camouflage part 14, so that the unity of the inner container 10 and the frame body 20 is enhanced, and the paired containers 1 can give the impression of being a single container as a whole.

[0036] The inner container 10 can also be made of hard resin, but when it is used as a refillable container, the main body 12 can be made of a thin, deformable film-like material, except for the neck 11 and the cover 14, which require strength. It can also be made of a transparent resin so as to show the remaining amount of the contents.

[0037] <Nozzle (Dispenser) 2>: The nozzle 2 is a member that seals the opening of the neck 11 of the inner container 10 and also discharges the contents inside the inner container 10. The nozzle 2 comprises a discharge part 2a having a discharge port for the contents, and a screw cap 2b that is attached to the inner container 10. A thread groove (not shown) is cut on the inner surface of the screw cap 2b, which screws into the screw thread 11 provided on the neck 11 of the inner container 10.

[0038] To use the paired container 1, the nozzle 2 is removed from the inner container 10 to which it is attached, and the inner container 10 is fitted into the mounting recess 22 of the frame 20. The nozzle 2 is then reattached to the inner container 10. Then, not only are the inner container 10 and the frame 20 joined by the engagement of their respective engagement portions, but the nozzle 2 joins the neck 11 of the inner container 10 with the reinforcing protrusions 24 of the frame 20, so that the nozzle 2, inner container 10, and frame 20 are all fully joined together and integrated. Therefore, despite having the inner container 10 and the frame 20, the whole can be used as a single container.

[0039] Although a typical embodiment of the inner container 10 and the frame body 20 has been described above, their size and shape are not particularly limited, and it is sufficient that the neck portion 11 fits into the mounting recess 22, the groove portions 31b and 14b engage with the support portions 23, and the inner container 10 is assembled to the frame body 20, and the frame body 20 can stand stably in this state when the bottom 25 of the frame body 20 is placed on the floor or the like.

[0040] Fig. 9 shows inner containers 10a to 10e having different types of outer shapes of the inner container 10. Fig. 10 shows frame bodies 20a and 20b having different types of outer shapes of the frame body 20. Fig. 11 shows frame bodies 20c and 20d having different types of outer shapes of the frame body 20. The outer shapes shown in these figures are examples of the inner container 10 and the frame body 20.

[0041] Although the preferred embodiment of the present invention has been described in detail above, the present invention is not limited to the specific embodiment described above, and various modifications and variations are possible within the scope of the gist of the present invention described in the claims of the utility model registration.
