[0004] [Patent Document 1] Patent No. 6370549 [Overview of the Initiative] [Problems that the invention aims to solve]

[0005] The present invention aims to develop a blister container that does not use a backing card, allows for stacking of blister containers, and enables one-handed opening of the blister container. [Means for solving the problem]

[0006] The present invention relates to a blister container having a container body and a lid that are provided as a continuous unit, and is a blister container that has a structure that allows for stacking, ensures the safety of the stored cosmetic containers, and facilitates the opening operation.

[0007] The main components of this invention are as follows: 1. In a blister container comprising a container body and a lid for housing cosmetic containers, The container body and the lid have a connecting part on one side that connects them. The container body has a storage compartment and an overlapping recess on the underside that is larger than the outer diameter of the top of the lid. The container storage section has a low wall section on the wall of the side opposite the side having the connecting section. The lid has an outer circumference that contacts the outer circumference of the container storage area when the lid and container body are closed via the connecting portion, a ceiling portion smaller than the overlapping recess of the container body, and stepped portions at the corners that are lower than the ceiling portion, and the outer wall of the stepped portion extends from the outer circumference of the lid toward the ceiling portion.

The blister container for cosmetic containers according to 1., characterized in that the low wall portion is also provided on the connection side of the container storage portion. 3. The blister container for cosmetic containers according to 1., characterized in that the base of the top portion of the lid is at a height that abuts against the cosmetic container. A blister container containing cosmetic containers, which consists of a blister container for cosmetic containers as described in any of sections 4.1 to 4.3, with a cosmetic container filled with cosmetic products set inside the blister container. 5. A method for manufacturing a blister container containing a packaged cosmetic container by the following steps. Step I: Step of preparing cosmetic containers filled with cosmetic ingredients. Step II: The process of preparing a blister container as described in any of steps 1 to 3. Step III: The process of opening the blister container, setting the cosmetic container into the blister container, and manufacturing the blister container containing the cosmetic container as described in 4. Process IV: The process of loading the blister containers containing cosmetic products into the outer box for packaging. [Effects of the Invention]

[0008] 1. This blister container has the container body and lid integrated into one unit, eliminating the need for a backing card and simplifying packaging materials, thus enabling recycling. 2. The lid can be fitted onto the overlapping recess on the underside of the container body, allowing the blister containers to be stacked and saving space. When stacking blister containers, the base of the ceiling has a rib function, preventing the lid from being crushed under pressure. Furthermore, the stepped portion also exhibits a rib function. 3. By pushing the outer circumference of the front lid of the low wall section of the container storage compartment from the front, the lid is pushed upward, allowing it to be opened with one hand. In particular, when setting cosmetic containers, the blister container can be opened with one hand and the cosmetic container can be loaded with the other, improving work efficiency. 4. The stepped sections at the corners function as ribs on the lid, preventing deformation of the blister container. When the top of the blister container containing the cosmetic is pressed, the stepped sections prevent crushing, thus protecting the stored cosmetic from damage and ensuring safety. When the front outer periphery is pressed, the front surface deforms (the sides do not), and the lid is biased in the opening direction along the U-shaped side edge of the front lower wall, making it easier to open. When blister containers are stacked, the rib function provided by the lid of the lower blister container containing cosmetics can support the upper blister container containing cosmetics without being crushed. 5. The blister container of the present invention can streamline the operation of setting a cosmetic container in the blister container and save space in the working space. The place where cosmetics are filled into the cosmetic container and the place where the blister container is formed are separate, and it is assumed that the place where these are collected and set, and further the place where they are loaded into the cosmetic outer box are different. For example, depending on the sales route and sales area of cosmetics, the exterior may be different, and in that case, conveyance stability can be ensured when stacking and conveying five of each type. In the present invention, in particular, in the setting process, conveyance process, and outer box loading process, labor saving, space saving, and stable posture can be achieved.

Modes for Carrying Out the Invention

[0010] The present invention is a blister container that does not use a backing sheet, can be stacked, ensures the stability of the stored cosmetic container, and is easy to open. The basic structure of this blister container is a blister container comprising a container body for storing a cosmetic container and a lid. The container body and the lid are continuous with a connecting portion connecting the two on one side. On the container body, a container storage portion and a polymerization recess where the upper part of the lid overlaps are provided on the back side. The container storage portion has a low wall portion provided on the wall portion of the side opposite to the side having the connecting portion. The lid has an outer peripheral portion that contacts the outer periphery of the container storage portion on the main body side, a ceiling portion smaller than the outer peripheral portion, and a step portion lower than the ceiling portion at the corner. The outer wall of the step portion extends from the outer peripheral portion of the lid, and the ceiling portion of the lid is sized to be fitted into the polymerization recess of the container storage portion.

[0011] Since it is a blister container in which the container body and the lid are integrally provided at the connecting portion, the whole is made of the same plastic material, and it is a container that can easily simplify and recycle the packaging material. Since the ceiling portion of the lid can be fitted into the polymerization recess on the back surface of the container body, the blister containers can be stacked, and it is a blister container that can save space such as stacking by type. Since a low wall portion is provided on the container body side, when the lid is covered and the lid is pushed from the low wall portion side, the lid is deformed inward and receives an upward force, making it easier to open the lid. Therefore, the present invention is a blister container that can be easily opened by holding it with one hand and pushing the low wall portion side.

[0012] The blister container of the present invention can improve the efficiency of the operation of setting the cosmetic container in the blister container and save the working space. The place where the cosmetics are filled into the cosmetic container and the place where the blister container is formed are separate, and it is assumed that the place where these are collected and set, and further the place where they are loaded into the outer box for cosmetics is different. For example, depending on the sales route and sales area of cosmetics, the exterior may be different, and in that case, the stability of the posture during transportation can be ensured when stacking and transporting 5 of each type. In the present invention, particularly in the setting process, the transportation process, and the outer box loading process, labor saving, space saving, and stable posture can be achieved. Blister containers can be molded using commonly used plastics for blister container manufacturing, and transparent plastics can be used. Transparent plastics are suitable because they allow the cosmetic contents to be visible, and using plant-based or biodegradable plastics can reduce the environmental impact.

[0013] Embodiments are shown in Figures 1 to 6. Figure 4 shows a blister container 1 with the container body 2 and lid 3 in a partially open state, and Figure 5 shows a blister container 11 in a partially open state with the cosmetic container 100 housed in the container body 2. The outline of the blister container 1 will be explained using Figures 4 and 5. The blister container 1 is a rectangular container comprising a container body 2 and a lid 3 that house the cosmetic container 100. Within the limits that do not impair the effects of the present invention, it is also possible to make the container a shape other than rectangular to match the shape of the cosmetic container 100. The container body 2 and the lid 3 have a connecting portion 4 on one side that connects them, while the other three sides are separate, and the container body 2 and the lid 3 can be opened and closed using the connecting portion as a hinge.

[0014] The container body 2 has a container storage section 21 for storing cosmetic containers, and an overlapping recess 22 on its back surface that overlaps with the upper part of the lid. The container storage section 21 has a recess for storing containers formed by the storage wall section 23, and has a front low wall section 23a on the wall of the side opposite the side having the connecting section 4. The lid 3 has an outer peripheral portion 31 that contacts the outer peripheral surface 21a of the container storage portion 21 when the lid 3 and the container body 2 are closed via the connecting portion 4, a ceiling portion 32 that is smaller than the outer peripheral portion, and stepped portions 33 at the corners that are lower than the ceiling portion. The ceiling portion 32 of the lid 3 is sized to fit over the overlapping recess 22 of the container body 2. The container storage section 21 has a lock recess 51 on the outside of the storage wall portion, which is the outer peripheral surface 21a, and a lock projection 52 on the inside of the outer peripheral portion 31 of the lid 3 engages with it, thereby closing the container body 2 and the lid 3. Figure 5 shows a blister container 11 containing a cosmetic container 100, with the cosmetic container 100 stored in the container storage section 21. The height of the cosmetic container 100 and the depth of the container storage section 21 (the height inside the storage wall section 23) are approximately the same, and are held in place by the base 32a of the ceiling section 32.

[0015] When the lid 3 is closed, pressing the front outer circumference 31a of the lid 3, which corresponds to the front lower wall portion 23a of the container body 2, causes the front outer circumference 31a to indent significantly, acting as an upward force that biases the lid 3 in the opening direction, making it easy to open the lid. At this time, the stepped portion 33 at the corner of the lid 3 acts as a rib, and the indentation deformation is limited to the front outer circumference 31a, so the upward force is guided by the inclined surface of the front lower wall portion 23a on the container storage portion 21 side, causing the lid 3 to open.

[0016] The structure of blister container 1 is described in detail below, according to Figures 1, 2, and 3. Figure 1 shows the top, front, and side views of the blister container 1 in its unfolded state. Figure 2 shows a perspective view of the blister container opened, and Figure 3 shows a perspective view from the opposite side of Figure 2. Blister container 1 is manufactured using a common blister pack molding process, which involves heat-pressing a plastic sheet. The blister container 1 consists of a container body 2 and a lid 3, and the two are connected by a connecting part 4 on one side.

[0017] The container body 2 has a container storage section 21 and an overlapping recess 22 on its back surface that overlaps with the upper part of the lid. The container storage section 21 has a recess formed by a storage wall section 23 that can accommodate a cosmetic container. For the purposes of this explanation, the side facing the connection section 4 will be referred to as the "rear," and the side opposite the connection section will be referred to as the "front." The front and rear edges of the storage wall section 23 are provided with a U-shaped curved front low wall section 23a and a connection section side low wall section 23b. The storage wall portion 23 is formed from an outer peripheral surface 21a, an inner peripheral surface 21b, and a wall top surface 23c, widening below the wall top surface 23c. The inner peripheral surface 21b is formed almost vertically, and the outer peripheral surface 21a has an inclined surface. Since the blister container of the present invention is press-molded from a single plastic sheet, the storage wall portion 23 is formed by bending as shown in the cross-section of Figure 6, forming the outer peripheral surface 21a, inner peripheral surface 21b, and wall top surface 23c.

[0018] The inner circumferential surface 21b has a shape similar to the outer shape of the cosmetic container and is formed almost vertically. The corner portion 21c of the container storage section 21 is shaped to tightly press against the cosmetic container, thereby holding the cosmetic container in place. The outer circumferential surface 21a is tapered. Furthermore, two locking recesses 51 are provided on each of the four sides of the outer circumferential surface 21a. These locking recesses 51 engage with the locking protrusions 52 on the lid side. Note that there may be one or three or more locking recesses 51 on each side. The height of the inner circumferential surface 21b is smaller than the height of the outer circumferential surface 21a, and the height of the inner circumferential surface 21b is approximately the same as the height of the cosmetic container. By making the outer circumferential surface 21a higher than the inner circumferential surface 21b, an overlapping recess 22 is formed on the back side of the container body 2. If the outer circumferential surface 21a is made higher, the overlapping recess 22 becomes deeper, and the overlap with the lid 3 increases. The depth of the overlapping recess 22 can be adjusted to cover the area from the top portion 32 to the outer portion 31 of the lid 3. The U-shaped curved front low wall portion 23a and connection-side low wall portion 23b, provided on the front and rear edges of the storage wall portion 23, allow the cosmetic container 100 to be held by the fingers and easily attached to and detached from the container storage portion 21. Furthermore, when the lid 3 is pressed from the front low wall portion 23a while closed, the lid 3 deforms inward and is guided by the U-shaped curved edge, biasing it to open upward. As will be described later, the opening of the lid is also biased in the opening direction by the rib action of the stepped portion 33 on the lid 3 side, so the opening of the lid is facilitated by the combined action of both the lid and the container storage portion. A storage section flange 24 is formed on the outer edge of the container body 2. This storage section flange 24 is continuous with the lid section flange 34 via a connecting section 4. In this example, the front edge 24a of the storage section flange 24 is smaller than the front edge 34a of the lid section flange 34, and the corners 24b of the storage section flange 24 are formed to be large and angular. In this example, the upper wall surface 23c is at the same height as the stored cosmetic container and is formed to abut against the base 32a of the ceiling portion 32 on the lid 3 side, but the relationship is not limited to this.

[0019] The lid 3 has a lid flange 34 at its outer edge, an outer peripheral portion 31 rising from the lid flange 34, and a ceiling portion 32 above the outer peripheral portion 31. The outer periphery 31 is provided with stepped portions 33 at the corners and a base portion 32a of the ceiling portion 32 in the middle of the sides. The outer periphery 31 is tapered so as to be in contact with the outer periphery surface 21a that forms the overlapping recess 22 of the container storage portion 21. The outer periphery 31 is provided with two locking protrusions 52 on each of its four sides. These locking protrusions 52 engage with the locking recesses 51 on the container storage portion side. Note that there may be one or three or more locking protrusions 52 on each side. The ceiling portion 32 rises from a base portion 32a located in the middle of the outer peripheral portion 31 and is smaller than the outer peripheral portion 31. The base portion 32a is wider than the upper surface 23c of the storage wall portion 23 and is large enough to hold down the edge of the cosmetic container. A small, upwardly curved raised peripheral edge portion 32b is formed on the edge of the ceiling portion 32. The stepped portion 33 is provided at the corner of the outer peripheral portion 31 and rises from the base portion 32a of the ceiling portion 32. The outer wall 33a of the stepped portion 33 extends from the outer peripheral portion 31 of the lid 3 towards the ceiling. A lid flange 34 is formed on the outer edge of the lid. This lid flange 34 is continuous with the storage flange 24 via a connecting portion 4. In this example, the front edge 34a of the lid flange 34 is larger than the front edge 24a of the storage flange 24, and the corners 34b of the lid flange 34 are smaller.

[0020] The lid 3 has irregularities formed by the raised peripheral edge 32b of the ceiling portion 32, the stepped portion 33, and the base portion 32a of the ceiling portion 32, which provide a rib function as a whole. Therefore, it has higher deformation resistance compared to a uniform case where these features are not present. As a result, deformation can be prevented even when stacked. The base 32a of the ceiling portion 32 can press down on the upper edge of the stored cosmetic container 100, stabilizing the storage position of the cosmetic container 100 (see Figure 6). Furthermore, a gap is formed between the surface of the cosmetic 101 filled in the cosmetic container 100 and the ceiling portion 32 by the stepped portion 33 at the corner and the ceiling portion 32 which is positioned higher than the stepped portion. In addition, the raised peripheral edge 32b on the outer circumference of the ceiling portion 32 suppresses deformation even when the ceiling portion 32 is pressed down from above, preventing the ceiling portion 32 from contacting and damaging the cosmetic 101.

[0021] When the lid 3 is fitted onto the container body 2, the lid flange 34 is in contact with the storage flange 24. In this state, the locking projection 52 and the locking recess 51 engage, locking the lid 3 and the container body 2 together. However, this lock has an engagement force that allows it to be unlocked by hand. Unlocking can be done by pushing the front low wall portion 23a side, as described above, or by lifting and separating the lid flange 34 from the storage flange 24. Because the front edge and corners of the flanges of the lid 3 and the container body 2 are of different sizes, the user can easily and safely open the blister container 1 by pressing down on the corner 24b of the flange of the container body 2 and lifting the front edge 34a of the lid 3.

[0022] The connecting portion 4 is provided between one side of the storage portion flange 24 and the lid portion flange 34. As shown in the front view of Figure 1, the connecting portion 4 has a U-shaped curve 41 that is curved in a U shape on the lid 3 side. This U-shaped curve 41 can also be given a spring action that biases it in the closing direction. This makes it easier to close the lid 3 when the cosmetic container is set in the container storage portion 21.

[0023] Figure 6 shows a cross-section of the cosmetic containers in their assembled state. Figure 6(a) is a cross-sectional view, and Figure 6(b) shows a cross-section of the stacked containers. The cosmetic container 100 is stored in the container storage section 21 of the container body 2, and the lid 3 is fitted over it. The lid 3 has a raised peripheral edge 32b provided on the edge of the ceiling portion 32, a lower base 32a, an outer peripheral portion 31 that protrudes outward, and a lid flange 34 at the lower end of the outer peripheral portion 31. The container body 2 has an inner circumferential surface 21b rising from the bottom of the container storage section 21, passing through the upper wall surface 23c to the outer circumferential surface 21a, and a storage section flange 24 is provided at the lower end of the outer circumferential surface 21a. The storage section flange 24 is lower than the bottom of the container storage section 21, forming an overlapping recess 22. The base 32a, outer circumference 31, and lid flange 34 of the lid 3 are in contact with the upper wall surface 23c, outer circumference 21a, and storage flange 24 of the container body 2. Furthermore, the base 32a of the lid 3 abuts against the edge of the cosmetic container 100, stabilizing the cosmetic container 100. There is a space between the top portion 32 of the lid 3 and the cosmetic container 100, so that even if the top portion 32 is dented, it will not come into contact with the cosmetic. In addition to the raised peripheral edge 32b shown in the figure, a stepped portion also resists denting of the top portion 32 due to pressure, etc. Note that the stepped portion is provided at the corner of the lid and is therefore not shown in this cross-sectional view.

[0024] Figure 6(b) shows a cross-section of the blister containers 11 containing cosmetic containers stacked on top of each other. In this example, the depth of the overlapping recess 22 is set such that the part of the lid 3 above the base 32a fits into the overlapping recess 22. In this state, the weight of the upper blister container 11-2 is added to the ceiling 32 of the lower blister container 11-1, so the strength of the lid of the present invention is sufficiently maintained by the rib function. Furthermore, by setting the depth of the overlapping recess 22 to a depth such that the outer peripheral surface 21a of the container storage portion 21 of the upper blister container 11-2 contacts the outer peripheral portion 31 of the lid 3 of the lower blister container 11-1, the weight of the upper blister container 11-2 can be transmitted to the outer peripheral portion 31 of the lid 3 of the lower blister container 11-1.

[0025] The following process manufactures a blister container set with a packaged replacement cosmetic container. This technology requires tasks such as preparing the cosmetic, filling the cosmetic container with the cosmetic, molding the blister container, setting the cosmetic container and blister container together, and loading the blister container with the cosmetic container into an outer box. Step I: Step of preparing a cosmetic container 110 filled with cosmetic product. Step II: Step to prepare blister container 1, Step III: The process of opening the blister container 1, setting the cosmetic container 110 filled with cosmetic into the blister container 1, and manufacturing the blister container 11 with the cosmetic container 110 set inside. Step IV: The process of loading the blister container 11, which contains the cosmetic container 110, into the outer box for packaging.

[0026] Step I is the step of filling the prepared cosmetic into the cosmetic container 110. Empty cosmetic containers are delivered, and the prepared cosmetic is filled into the cosmetic containers. Step II is the process of forming the blister container of the present invention. Step III is the process of setting the cosmetic containers obtained in Step I into the blister containers obtained in Step II. This requires opening the delivered blister containers, but the blister containers of the present invention have lids that open easily when the front is pressed, making the opening process easy and allowing for easy setting of the cosmetic containers. The blister containers with the cosmetic containers set inside can be stacked, saving storage space. Management is also easier, such as separating and storing cosmetic products of multiple colors. Step IV is the process of loading the blister containers, which contain the cosmetic containers, into the outer box. The type of outer box used will vary depending on the sales route, sales region, season, etc.

[0027] The blister container of the present invention is effective in improving workability from step III onward. The ease of opening and closing improves setting efficiency, space saving is achieved by stacking, and the lid is resistant to dents and deformation from pressure, improving safety by preventing damage to cosmetics during handling such as moving. Even if customers touch the displayed products, the cosmetics are less likely to be damaged, reducing the amount of damaged products discarded at the store. As a result, even inexperienced workers can safely and efficiently perform the tasks from process III onward. Since processes III and beyond are often carried out in separate locations, it is important to be able to improve space efficiency, durability, work efficiency, transport safety, and display safety. Furthermore, since the blister container has a lid and container body as one unit, it can be disposed of without needing to be separated. [Explanation of Symbols]
