[Technical Field]

[0001] The present invention relates to a stick-type cosmetic container and a packaging body. [Background technology]

[0002] Conventionally, Patent Document 1 below discloses a cosmetic product in which a cosmetic and an applicator are sandwiched between opposing films. This cosmetic product is a simple container for use as a sample product, etc., in which the cosmetic and the applicator are welded together to form an airtight unit, and the film is opened before use. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2021-87685 Summary of the Invention [Problem to be solved by the invention]

[0004] In recent years, there has been a demand for eco-friendly stick-shaped cosmetic containers that reduce the number of parts as much as possible while maintaining the same quality as before, and that allow previously used parts to be reused.

[0005] Therefore, an object of the present invention is to provide an ecological stick-shaped cosmetic container and a package for packaging the same, which maintains high airtightness until opening, reduces the number of parts, and allows previously used parts to be reused. [Means for solving the problem]

[0006] The gist of this disclosure is as follows [1] to [6].

[0007] [1] A stick-shaped cosmetic container and packaging comprising: a stick-shaped cosmetic container that stores a stick-shaped cosmetic inside and from which the stick-shaped cosmetic can be seen through an opening at the tip; and a packaging body that sandwiches and packages the stick-shaped cosmetic container with film, wherein the packaging body has a welded portion that seals the stick-shaped cosmetic container up to the vicinity of the outer periphery by welding the films together, and the welded portion further has a tip-side annular portion that fits tightly around the outer periphery of the stick-shaped cosmetic container near the opening.

[0008] According to [1], the stick-shaped cosmetic container is sealed at the welded part of the film, so it can be sold without a cap, reducing the number of parts and being eco-friendly. Furthermore, the annular part at the tip of the welded part of the film seals the opening at the tip of the stick-shaped cosmetic container, so a high level of airtightness can be maintained until it is opened. Furthermore, when opening the package and removing the stick-shaped cosmetic container for use, the previously used cap and the container body with a built-in feeding mechanism for feeding the stick-shaped cosmetic can be reused, making it eco-friendly.

[0009] [2] The stick-shaped cosmetic container and packaging body described in [1], characterized in that the welded portion of the film has an annular retraction stopper located behind the tip-side annular portion to prevent the stick-shaped cosmetic container from retracting.

[0010] According to [2], the retraction stopper provided behind the annular portion at the tip prevents the stick-shaped cosmetic container from being pushed back, thereby ensuring that the opening at the tip of the stick-shaped cosmetic container is sealed.

[0011] [3] The stick-shaped cosmetic container and packaging body described in [2] are characterized in that the stick-shaped cosmetic container is provided with an annular flange portion that protrudes circumferentially from the outer peripheral surface rearward of the front-end annular portion, and the retraction stopper is provided as a rear-end annular portion at a position rearward of the flange portion and overlapping with the flange portion in the axial direction.

[0012] According to [3], the action and effect of [2] can be reliably achieved.

[0013] [4] The stick-shaped cosmetic container and packaging described in [3] are characterized in that a tail plug that detachably closes the stick-shaped cosmetic hole is provided at the rear end of the stick-shaped cosmetic hole through which the stick-shaped cosmetic passes in the stick-shaped cosmetic container, and a notch for opening the packaging is provided behind the rear-end annular portion in a position that allows the rear end of the stick-shaped cosmetic container to be exposed.

[0014] According to [4], when replacing a stick-shaped cosmetic container with a stick-shaped cosmetic container in an unopened package for the purpose of changing the color of the stick-shaped cosmetic, for example, the stick-shaped cosmetic container can be inserted into the opened package and the tail plug attached, with the rear end annular portion acting as a retraction stopper, allowing it to be used as a cap. Furthermore, because the rear end of the stick-shaped cosmetic container is exposed from the opened package, it is easy to grasp and to easily insert and remove it from the opened package, which serves as a cap. Furthermore, the tail plug further enhances the airtightness before opening.

[0015] [5] The stick-shaped cosmetic container and packaging body described in [1], characterized in that the stick-shaped cosmetic container has a container body with a built-in delivery mechanism for delivering the stick-shaped cosmetic.

[0016] [5] achieves substantially the same effects and advantages as [1]. That is, since the stick-shaped cosmetic container is sealed at the welded portion of the film, it can be sold without a cap, reducing the number of parts and being eco-friendly. In addition, the annular portion at the tip of the welded portion of the film seals the opening side of the tip of the stick-shaped cosmetic container, so a high level of airtightness can be maintained until it is opened. Furthermore, since the container body has a built-in feeding mechanism, when the package is opened and the stick-shaped cosmetic container is taken out for use, the previously used cap can be reused, which is eco-friendly.

[0017] [6] The stick-shaped cosmetic container and packaging described in [5] are characterized in that the welded portion of the film has an annular retraction stopper behind the annular portion at the tip end to prevent the stick-shaped cosmetic container from retracting, and a notch for opening the packaging is provided behind the retraction stopper.

[0018] According to [6], the retraction stopper provided behind the annular tip portion prevents the stick-shaped cosmetic container from being pushed back, thereby reliably sealing the open end of the stick-shaped cosmetic container. Furthermore, when replacing a stick-shaped cosmetic container with a stick-shaped cosmetic container in an unopened package for the purpose of changing the color of the stick-shaped cosmetic, for example, inserting the stick-shaped cosmetic container into the opened package prevents the stick-shaped cosmetic container from retracting, ensuring airtightness and allowing it to be used as a cap.

[0019] [7] The stick-shaped cosmetic container and packaging body described in [6], characterized in that the notch is provided at a position that allows the rear end of the stick-shaped cosmetic container to be exposed.

[0020] According to [7], the rear end of the stick-shaped cosmetic container is exposed from the package after opening, making it easy to grasp and easy to insert into and remove from the package after opening, serving as a cap. [Effects of the Invention]

[0021] Thus, according to the present invention, it is possible to provide an eco-friendly stick-shaped cosmetic container and a packaging body for packaging the same, which can reduce the number of parts while maintaining high airtightness until the container is opened and also allows previously used parts to be reused.

DETAILED DESCRIPTION OF THE INVENTION

[0023] Preferred embodiments of a stick-type cosmetic container and packaging body according to the present invention will now be described with reference to Figures 1 to 5. Figure 1 shows a first embodiment of the present invention, Figure 2 shows a second embodiment of the present invention, Figure 3 shows the action and effect of the second embodiment of the present invention, Figure 4 shows a third embodiment of the present invention, and Figure 5 shows a fourth embodiment of the present invention. In each figure, the same elements are given the same reference numerals, and duplicate explanations will be omitted.

[0024] First, a first embodiment will be described, as shown in Fig. 1. Fig. 1 is a vertical cross-sectional view showing a stick-type cosmetic container and a package according to the first embodiment of the present invention.

[0025] As shown in FIG. 1, the first embodiment comprises a stick-shaped cosmetic container 1 that contains a stick-shaped cosmetic M inside and from which the stick-shaped cosmetic M can be extracted from an opening 1a provided at the tip, and a packaging body 2 that sandwiches and packages the stick-shaped cosmetic container 1 between films 2a, 2a that face each other in a direction perpendicular to the plane of the page.

[0026] The stick-type cosmetic container 1 is configured in a tapered cylindrical shape and is what is called a front tube, constituting the front portion of a stick-type cosmetic dispensing container that stores stick-type cosmetic M and dispenses the stick-type cosmetic M. The cylindrical shape of the stick-type cosmetic container 1 can be, for example, a cylindrical cross-section, an elliptical cross-section, or a polygonal cross-section, etc. As the stick-type cosmetic M, eyeliner, eyebrow pencil, lip liner, etc. can be appropriately used, and the shape of the stick-type cosmetic M can also be, for example, a circular cross-section, an elliptical cross-section, a polygonal cross-section, etc.

[0027] The stick-shaped cosmetic material hole 1b, which accommodates the stick-shaped cosmetic material M and through which the stick-shaped cosmetic material M passes, extends from the opening 1a toward the rear of the stick-shaped cosmetic material container 1, and an enlarged diameter hole 1c, which communicates with the stick-shaped cosmetic material hole 1b and which is enlarged in diameter to open rearward, is provided at the rear of the stick-shaped cosmetic material container 1. The enlarged diameter hole 1c is a space for accommodating a so-called dispensing mechanism that enables the stick-shaped cosmetic material M to be dispensed.

[0028] In addition, a ring-shaped flange portion 1d protruding in the circumferential direction is provided on the outer peripheral surface of the stick-type cosmetic container 1 slightly forward of the enlarged diameter hole 1c to prevent the stick-type cosmetic container 1 from moving backward.

[0029] A circular recess 1e is provided on the outer peripheral surface of the stick-type cosmetic container 1 slightly rearward of the flange 1d, into which a cylindrical, bottomed container body, which constitutes the rear portion of the stick-type cosmetic dispensing container, is attached so as to be rotatable but immovable in the axial direction. This container body houses a dispensing mechanism for dispensing the stick-type cosmetic material M.

[0030] The recess 1e of the stick-type cosmetic container 1 is attached to the front side of the container body so as to be rotatable but immovable in the axial direction, and when they are rotated relative to each other, the screwing action of the feeding mechanism, which has, for example, male and female screw protrusions, comes into play, feeding out the piston as a moving body and dispensing the stick-type cosmetic M. Note that instead of the piston, a core chuck that grips the stick-type cosmetic M with multiple gripping pieces can also be used, in which case multiple gripping piece grooves that allow the gripping pieces to move are provided in series around the periphery of the stick-type cosmetic hole 1b.

[0031] On the other hand, the packaging body 2 has a welding portion 2b that seals the stick-shaped cosmetic container 1 up to the vicinity of the outer periphery by welding the films 2a, 2a together.

[0032] The welded portion 2b is provided with a distal annular portion 2c that fits closely around the outer periphery of the stick-type cosmetic container 1 near the opening 1a to keep the stick-type cosmetic M airtight.

[0033] Additionally, the welded portion 2b is provided with an annular retraction stopper 2d, located rearward of the front annular portion 2c, that prevents the stick-type cosmetic container 1 from retracting. In this case, this retraction stopper 2d is provided as a rear annular portion at a position rearward of the flange 1d of the stick-type cosmetic container 1 and overlapping with the flange 1d in the axial direction. This rear annular portion 2d as a retraction stopper may or may not be in contact with the stick-type cosmetic container 1.

[0034] Furthermore, the welded portion 2b has a notch (slit) 2e for opening the packaging body 2 at a position facing the rear end of the packaging body 2. In this case, the notch 2e is provided rearward of the rear end side annular portion 2d, and when removing and using the stick-shaped cosmetic container 1, the packaging body 2 can be opened at the notch 2e as a boundary.

[0035] According to the stick-type cosmetic container 1 and packaging body 2 of the first embodiment configured as described above, the stick-type cosmetic container 1 is sealed at the welded portion 2b of the film 2a, so it can be sold without a cap, reducing the number of parts and being eco-friendly. Furthermore, the opening 1a at the tip of the stick-type cosmetic container 1 is sealed by the annular portion 2c at the tip end of the welded portion 2b of the film 2a, so a high level of airtightness can be maintained until the container is opened. Furthermore, when the packaging body 2 is opened and the stick-type cosmetic container 1 is removed for use, the previously used cap and the container body with a built-in feeding mechanism for feeding the stick-type cosmetic M can be reused, making it eco-friendly.

[0036] Furthermore, the welded portion 2b of the film 2a is provided with an annular retraction stopper 2d behind the tip-side annular portion 2c to prevent the stick-type cosmetic container 1 from retracting, thereby preventing the stick-type cosmetic container 1 from being pushed back and ensuring that the opening 1a at the tip of the stick-type cosmetic container 1 is securely sealed.

[0037] In particular, the retraction stopper 2d is provided as a rear end annular portion at a position rearward of the flange portion 1d of the stick-type cosmetic container 1 and overlapping with the flange portion 1d in the axial direction, thereby ensuring the above-mentioned sealing action and effect.

[0038] In addition, when the stick-type cosmetic container 1 is tapered as in this embodiment, the front-end annular portion 2c, which fits closely to the outer periphery of the stick-type cosmetic container 1 in the vicinity of the opening 1a, is not able to prevent rearward movement, so a back-off stopper (rear-end annular portion) 2d is effective.

[0039] Incidentally, although the notch 2e is provided here as it is particularly preferable, the notch 2e may be omitted, and the welded portion 2b may be opened from anywhere using scissors or the like.

[0040] FIG. 2 is a longitudinal cross-sectional view showing a stick-type cosmetic container and a packaging body according to a second embodiment of the present invention, and FIG. 3 is a longitudinal cross-sectional view for explaining the action and effect of the stick-type cosmetic container and packaging body according to the second embodiment of the present invention.

[0041] The first difference between this second embodiment and the first embodiment is that, as shown in Figure 2, a tail plug 3 that detachably closes the stick-shaped cosmetic hole 1b is provided at the rear end of the stick-shaped cosmetic hole 1b of the stick-shaped cosmetic container 1. The second difference between the second embodiment and the first embodiment is that the notch 2e for opening the package 2 is replaced with a notch 2f located behind the rear-end annular portion 2d so that the rear end of the stick-shaped cosmetic container 1 can be exposed.

[0042] According to the second embodiment configured as described above, in addition to the effects and advantages of the first embodiment, when replacing the stick-type cosmetic container 1 with the stick-type cosmetic container 1 in the unopened package 2 for purposes such as changing the color of the stick-type cosmetic M, the stick-type cosmetic container 1 can be used as a substitute for a cap by inserting the stick-type cosmetic container 1 into the opened package 2 and fastening the tail plug 3, with the rear end annular portion 2d acting as a retainer, as shown in Fig. 3. Furthermore, because the rear end of the stick-type cosmetic container 1 is exposed from the opened package 2, it is easy to grasp and to insert and remove it from the opened package 2, which serves as a substitute for a cap. Furthermore, as shown in Fig. 2, the tail plug 3 can further improve airtightness before opening.

[0043] FIG. 4 is a vertical cross-sectional view showing a stick-type cosmetic container and a package according to a third embodiment of the present invention.

[0044] 4, the third embodiment comprises a rod-type cosmetic container 10 in which a so-called front tube 1 (the stick-type cosmetic container 1 of the first embodiment) as the front part of the container and a so-called container body 4 as the rear part of the container with a built-in dispensing mechanism are mounted rotatably but immovable in the axial direction, and in which relative rotation between the front tube 1 and the container body 4 activates the screwing action of the dispensing mechanism to dispense a stick-type cosmetic M, and a package 12 in which the rod-type cosmetic container 10 is sandwiched between opposing films 12a, 12a for packaging. Here, the rod-type cosmetic container 10 packaged in the package 12 is what is known as a stick-type cosmetic dispensing container.

[0045] The container body 4 is cylindrical with a bottom and is elongated in the axial direction, and the packaging body 12 is also elongated in the axial direction to match the container body 4.

[0046] The welded portion 12b, which seals the stick-shaped cosmetic container 10 up to the vicinity of its outer periphery by welding the films 12a, 12a together, is provided with a tip-side annular portion 12c that fits closely to the outer periphery of the front tube 1 near the opening 1a, as in the first embodiment.

[0047] Additionally, the welded portion 12b is provided with an annular retraction stopper 12d that prevents the stick-type cosmetic container 10 from retracting, at a position rearward of the front annular portion 12c and rearward of the rear end portion of the container body 4. This retraction stopper 12d may or may not be in contact with the stick-type cosmetic container 10.

[0048] Also, in the welded portion 12b, a notch 12e for opening the package 12 is provided rearward of the retraction stopper 12d, as in the second embodiment.

[0049] According to the third embodiment configured as described above, as in the first embodiment, the stick-type cosmetic container 10 is sealed at the welded portion 12b of the film 12a, allowing it to be sold without a cap, reducing the number of parts and making it eco-friendly. Furthermore, the leading annular portion 12c of the welded portion 12b of the film 12a seals the opening 1a at the leading end of the stick-type cosmetic container 10, maintaining a high level of airtightness until it is opened. Furthermore, when opening the package 12 and removing and using the stick-type cosmetic container 10, the previously used cap can be reused, making it eco-friendly. When opening this package 12, the notch 12e is not necessary; opening can be done from anywhere on the welded portion 12b, for example, with scissors or the like.

[0050] Furthermore, as in the first embodiment, the welded portion 12b of the film 12a is provided with an annular retraction stopper 12d behind the tip-side annular portion 12c that prevents the stick-type cosmetic container 10 from retracting, thereby preventing the stick-type cosmetic container 10 from being pushed back and ensuring that the opening 1a at the tip of the stick-type cosmetic container 10 is securely sealed.

[0051] Furthermore, as in the second embodiment, the notch 12e for opening the packaging body 12 is located behind the retraction stopper 12d. Therefore, when replacing the stick-shaped cosmetic container 10 with the stick-shaped cosmetic container 10 in the unopened packaging body 12 for purposes such as changing the color of the stick-shaped cosmetic M, the stick-shaped cosmetic container 10 can be inserted into the opened packaging body 12, whereby the retraction stopper 12d prevents the stick-shaped cosmetic container 10 from retracting, ensuring airtightness, and allowing it to be used as a cap.

[0052] FIG. 5 is a vertical cross-sectional view showing a stick-type cosmetic container and a package according to a fourth embodiment of the present invention.

[0053] The first difference between this fourth embodiment and the third embodiment is that, as shown in FIG. 5, instead of the axially long container body 4 of the third embodiment, a container body 5 that is short in the axial direction is used, resulting in a mini-type stick-type cosmetic container 20.

[0054] The second difference between the fourth embodiment and the third embodiment is that the annular retraction stopper 12d, which was located at the rear of the container body 4 to prevent the stick-type cosmetic container 20 from retracting, has been replaced with a rear end annular portion (annular retraction stopper) 12f, which, as in the first embodiment, is located rearward of the flange portion 1d of the front tube 1 and overlaps with the flange portion 1d in the axial direction, and the notch 12e for opening the packaging body 12 has been replaced with a notch 12g which is located rearward of the rear end annular portion 12f and at a position where the rear end of the stick-type cosmetic container 20 can be exposed.

[0055] The fourth embodiment configured as described above provides the same functions and effects as the third embodiment. Specifically, because the stick-shaped cosmetic container 20 is sealed at the welded portion 12b of the film 12a, it can be sold without a cap, reducing the number of parts and being eco-friendly. Furthermore, the leading annular portion 12c of the welded portion 12b of the film 12a seals the opening 1a at the leading end of the stick-shaped cosmetic container 20, maintaining a high level of airtightness until it is opened. Furthermore, when opening the package 12 and removing and using the stick-shaped cosmetic container 20, the previously used cap can be reused, making it eco-friendly. When opening this package 12, the notch 12g is not necessary; opening can be done from anywhere on the welded portion 12b, for example, with scissors or the like.

[0056] Furthermore, the welded portion 12b of the film 12a has a rear end annular portion 12f behind the front end annular portion 12c that prevents the stick-shaped cosmetic container 20 from moving backward, thereby preventing the stick-shaped cosmetic container 20 from being pushed back and ensuring that the opening 1a at the front end of the stick-shaped cosmetic container 20 is securely sealed.

[0057] Furthermore, because the notch 12g for opening the packaging 12 is located behind the rear annular portion 12f, when replacing the stick-shaped cosmetic container 20 with the stick-shaped cosmetic container 20 of an unopened packaging 12 for purposes such as changing the color of the stick-shaped cosmetic M, the stick-shaped cosmetic container 20 can be used as a substitute for a cap by inserting it into the opened packaging 12, with the rear annular portion 12f preventing the stick-shaped cosmetic container 20 from moving backward, ensuring airtightness. In addition, because the notch 12g is located behind the rear annular portion 12f in a position that allows the rear end of the stick-shaped cosmetic container 20 to be exposed, the rear end of the stick-shaped cosmetic container 20 is exposed from the opened packaging 12, making it easy to grasp and insert into and remove from the opened packaging 12, where it serves as a cap.

[0058] In addition, this mini-type stick cosmetic container 20 can be used as is to dispense and apply the stick cosmetic M, but it is also possible to use the male screw protrusions 5a provided on the outer surface of the container body 5 to detachably attach a long, bottomed cylindrical holder tube in the axial direction to the container body 5 by screwing it onto the container body 5, thereby improving usability when drawing.

[0059] Although the present invention has been specifically described above based on the embodiments thereof, the present invention is not limited to the above embodiments and various modifications are possible. [Explanation of symbols]
