Abstract
Description
[Technical Field]
[0001] The present invention relates to an improved container for containing a stick product. More specifically, the present invention relates to a container that allows a stick product in a holder cup to be moved between an extended position, in which the product in the holder cup can be applied by a consumer, and a retracted position. The present invention also relates to a method for assembling such a container. [Background technology]
[0002] A known type of container for stick-shaped products features a base permanently connected to a cylindrical inner body and a cam sleeve positioned around the inner body so that the cam sleeve and inner body can rotate relative to one another. The inner body is hollow and has a wall with at least one longitudinal slot extending therethrough. The cam sleeve has an inner wall characterized by at least one helical groove extending along a substantial length of the inner wall. A holder cup for stick-shaped products is provided and includes at least one cam follower in the form of a lug. When the holder cup is fitted within the inner body, the lug extends through the longitudinal slot of the inner body to engage with the helical groove of the cam sleeve. In this configuration, when the inner body is rotated relative to the cam sleeve, the helical groove of the cam sleeve applies pressure to the lug of the holder cup, driving the holder cup up and down within the inner body while the lug rides in the longitudinal slot. In this manner, the stick-shaped product is moved between an advanced position and a retracted position.
[0003] The holder cup is typically assembled to the top of the inner body. However, the lugs of the holder cup extend beyond the circumference of the inner body, and the top of the inner body may not be stretchable or flexible enough to allow the lugs to pass through. In fact, to facilitate insertion of the inner body into the cam sleeve, the upper outer edge of a conventional inner body is tapered, and this taper adds rigidity around the top periphery of the inner body. Also, even if the lugs of the holder cup can be forced into the top of the inner body, there is a high possibility that both the inner body and the lugs will sustain some damage. To alleviate this problem, some inner bodies (50; see FIG. 14 ) are designed with a secondary slot (50a) that extends from the top of one of the longitudinal slots and opens onto the upper edge of the inner body. This creates a break or gap around the top periphery of the inner body. This gap adds some flexibility to the upper portion of the inner body. Nevertheless, during assembly of the holder cup and inner body, the top of the inner body needs to be held open with a tool so that the holder cup can be inserted into the inner body without scratching or otherwise damaging the top or lugs of the inner body. However, even with this extra step of holding the top of the inner body open, the holder cup must be inserted at an angle so that one lug can be inserted before the other. This is a significant drawback in the assembly process. In some cases, two secondary slots are used so that the holder cup can be inserted into the inner body upright, but the two gaps around the top of the inner body create their own problems.
[0004] After the holder cup is inserted into the top of the inner body, the inner body and cam sleeve are assembled by inserting the top of the inner body into the bottom of the cam sleeve. As mentioned above, secondary slots and gaps around the periphery of conventional inner bodies allow the upper portion of the inner body to flex. Additionally, the outer edge of the inner body is tapered. Both of these features facilitate insertion of the inner body into the cam sleeve. However, the holder cup must be lowered to its retracted position before the top of the inner body can flex inward. This has at least two disadvantages. First, it is merely an extra step in the assembly process. Second, it would be advantageous for the product filler to receive the inner body-holder cup subassembly with the holder cup in its extended position, ready for filling. Otherwise, the filler must perform this step.
[0005] More serious problems caused by the circumferential gap at the top of the inner body relate to performance and perception. The circumferential gap tends to loosen the assembly between the inner body and the holder cup. This causes some wobble of the holder cup and stick product when the holder cup is raised and lowered, and even when the holder cup is in its fully extended position. This wobble makes it difficult to control the application of the product to the application surface and, at the same time, conveys a poor image to consumers. It should also be noted that the secondary slots and circumferential gaps of conventional inner bodies are generally visible to consumers, and the aesthetic impact of the asymmetry is negative. While some efforts can be made to obscure the circumferential gap at the top of the inner body, these are not completely effective and merely add another step to the manufacturing and / or assembly process.
[0006] The advantages of an inner body without a secondary slot at its top end and without any discontinuities or gaps around the periphery of the top of the inner body include: the top of the inner body does not need to be held open with a tool, the holder cup does not need to be retracted before assembling the inner body and cam sleeve, the holder cup does not need to be extended before product filling, the manufacturer can supply the product filler with the inner body / holder cup subassembly ready for filling, rattle during operation is reduced, and any unsightly appearance can be hidden from view.
[0007] Problems that the invention aims to solve A primary object of the present invention is to provide a container for a stick product that utilizes an inner body that has a continuous upper periphery, i.e., no gaps around the upper periphery.
[0008] Another object of the present invention is to provide an improved method for assembling containers for stick-like products. Summary of the Invention
[0009] The container (10) for a stick-like product (7) according to the present invention comprises a cap (1), a base (2), an A-shell (3), a cam sleeve (4), an inner body (5), and a holder cup (6). The inner body is continuous along its upper periphery, meaning that the longitudinal slots in the inner body do not open to the upper periphery of the inner body. Significant advantages in assembly are realized. The container according to the present invention can be useful for all types of stick-like products that are applied to a surface by drawing the product across the surface. These include lipstick, lip balm, deodorant stick, antiperspirant stick, glue stick, etc. [Brief explanation of the drawings]

[0011] Throughout this specification, the term "comprises" means that the collection of objects is not necessarily limited to those explicitly listed, but may or may not include additional objects.
[0012] For purposes of the present invention, a stick product is an elongated mass of solid or semi-solid product that is capable of supporting its own weight when the elongated mass is suspended at one end.
[0013] Cap and base Figure 1 depicts a cap (1) and base (2) for a container (10) for a stick product (7) according to the present invention. The cap comprises an open bottom (1a) designed to cooperate with the base and a closed top (1b). The cap protects the contents of the container from the ambient environment and is removably secured to the base by some means, such as an interference fit or snap fit.
[0014] One embodiment of a base (2) is shown in FIG. 2. The base includes a closed bottom (2a) and an open top (2b) separated by a sidewall (2d). The closed bottom and sidewall define the interior space or interior (2e) of the base. The base supports an A-shell (3) and an inner body (5) by receiving their respective lower ends concentrically within the base. When assembled, the A-shell and base rotate independently, while the base and inner body rotate as a unit. To accomplish this, the interior of the base may be provided with a first set of gear teeth (2i) located on a concentric ring (2c), which is supported on the closed bottom of the base.
[0015] A shell and cam sleeve Referring to Figures 3 and 4, the A-shell (3) is a cylindrical tube with an open bottom (3a) and an open top (3b) separated by a sidewall (3d). The bottom of the A-shell rests inside the base (2) between the sidewall (2d) and the concentric ring (2c). The cam sleeve (4) (see Figures 5, 6, and 9) comprises a generally cylindrical body with an open top (4b) and an open bottom (4a) separated by a sidewall (4d). The cam sleeve is shorter than the A-shell. The entire length of the cam sleeve is positioned inside the A-shell so that none of the cam sleeve protrudes beyond the A-shell. There is a very tight fit between the cam sleeve's sidewall (4d) and the A-shell's sidewall (3d), and some means is used to ensure that the A-shell and cam sleeve rotate as a unit. For example, during assembly, a fixture on the assembly line is used to set the cam sleeve at a predetermined position or height within the A-shell. The cam sleeve is fixed to the A-shell, usually by gluing or crimping it together at a point on the outside of the A-shell.
[0016] The side wall (4d) of the cam sleeve (4) is substantially solid and has an outer surface (4e) and an inner surface (4f). The inner surface is provided with at least one spiral groove, preferably two spiral grooves (4c, 4c'). The spiral groove begins at the top (4b) of the cam sleeve and completes several or partial revolutions before terminating near the bottom (4a) of the cam sleeve. The cam sleeve can also receive the inner body (5) concentrically within itself. When positioned around the inner body, the cam sleeve and inner body can rotate independently of each other.
[0017] Inner body and holder cup Referring to Figures 7-9 and 11-13, the inner body (5) according to the present invention is generally cylindrical and includes an open top (5b) and an open bottom (5a) separated by a sidewall (5d). During assembly, the bottom of the inner body is inserted into the top (4b) of the cam sleeve (4). In final assembly, the inner body protrudes from both ends of the cam sleeve and is rotatable relative to the cam sleeve. A second set of gear teeth (5i) is located near the bottom of the inner surface (5h) of the sidewall. The bottom of the inner body is designed to be received within the base (2) so that the first set of gear teeth (2i) mesh with the second set of gear teeth (5i). When assembled, the base and inner body rotate together. As explained below, the order of assembly is important.
[0018] At least one, and preferably two, longitudinal slots (5c, 5c') pass through the side wall (5d) of the inner body (5), 180° apart. The upper and lower ends of the longitudinal slots may be formed as horizontal slot extensions (5e, 5e'). By design, neither the longitudinal nor horizontal slots open to the top (5b) of the inner body, as is typically done. That is, there are no secondary slots, as discussed above. In fact, the circumference of the top (5b) of the inner body is continuous or uninterrupted, which is important. The top of the inner body is also formed to overhang (5k) the side wall (5d). During assembly, the inner body can be inserted into the cam sleeve (4) by depressing the overhang. The overhang has an inwardly sloping surface (5g) that slopes toward the interior of the inner body, unlike the outwardly sloping surfaces commonly found.
[0019] Above the height of the at least one longitudinal slot (5c, 5c') of the inner body (5), at least one horizontal bead, preferably two horizontal beads (5f, 5f'), extend along the side wall (5d). The diameter of the inner body at the height of the horizontal bead is slightly larger than the diameter of the upper part (4b) of the cam sleeve (4), but smaller than the inner diameter of the A-shell (3). Thus, when the bottom of the inner body is inserted into the upper part of the cam sleeve, the horizontal bead comes into contact with the upper part of the cam sleeve, and acts as a stop to prevent further insertion of the inner body once it is fully inserted into the cam sleeve (see Figure 8).
[0020] Once the inner body is fully inserted into the cam sleeve, it must be prevented from retracting. For example, when the base (2) is inserted into the bottom (5a) of the inner body, some resistance exists that could cause the inner body to move relative to the cam sleeve (4). To prevent this, a flexible tab (5j) is located on the side wall (5d) immediately below at least one of the longitudinal slots (5c, 5c'). The flexible tab is connected to the side wall of the inner body by a living hinge that urges the tab to protrude outward from the side wall. The flexible tab has sloped sides and a horizontal top surface. When the sloped surface of the tab contacts the top (4b) of the cam sleeve, the tab flexes inward, allowing the inner body to be inserted. However, once the tab emerges from the bottom (4a) of the cam sleeve, it returns to its extended position, and the horizontal surface of the tab prevents upward movement of the inner body relative to the cam sleeve. In the fully assembled container (10), the inner body protrudes beyond both ends of the cam sleeve, but the top portion (5b) of the inner body does not protrude beyond the top portion (3b) of the A-shell (3).
[0021] Referring to Figures 8 and 10-12, the holder cup (6) comprises a bottom (6a) that can be opened or closed and an open top (6b). The top and bottom are separated by a side wall (6d). The holder cup can receive and hold a stick-shaped product (7) that can be inserted into the holder cup through the open top. At least one lug, preferably two lugs (6c, 6c'), are located 180° apart to align with the longitudinal slots (5c, 5c') of the inner body (5). Optionally, the lugs may be located on flexible sections of the side wall. For example, in Figure 10, the lugs rest on thin strips of the side wall such that inward pressure on the lugs causes them to pinch inward. When pressure is released, the lugs return to their original position. This facilitates assembly of the holder cup into the inner body. For example, when the bottom (6a) of the holder cup is inserted through the top (5b) of the inner body, the lugs contact the inclined surfaces (5g) of the protrusions (5k), clamping the lugs inward. When the holder cup reaches a specified depth inside the inner body, the lugs of the holder cup enter the horizontal slots (5e, 5e') in the inner body and return to their original positions.
[0022] Alternatively, the plastic material of the upper portion of the inner body 5 can be sufficiently flexible to allow the lugs 6c, 6c' of the holder cup 6 to be forced through the upper portion 5b of the inner body and into the longitudinal slots 5c, 5c'. Depending on the assembly sequence, it may be preferable for the inner body and cam sleeve 4 to remain in a partially assembled configuration prior to insertion of the holder cup. Referring to FIG. 12, in this partially assembled configuration, the horizontal beads 5f, 5f' of the inner body are not yet in contact with the upper portion 4b of the cam sleeve, and the horizontal slot extensions 5e, 5e' are not covered by the cam sleeve. Also, if an A-shell is present at this stage of assembly, the upper portion 5b of the inner body rests above the upper portion 3b of the A-shell 3 (see FIG. 13). The flexible tabs 5j of the inner body exert outward pressure against the inner surface 4f of the cam sleeve. Preferably, the pressure is sufficient to maintain the inner body and cam sleeve in this partially assembled configuration. The purpose of this configuration is to aid in the assembly of the holder cup (6) onto the inner body top (5b) without interference from the cam sleeve or A-shell. When the holder cup (with or without the stick product 7) is inserted through the inner body top, the lugs of the holder cup are seated within the longitudinal slots. At this point, by depressing the ledge (5k) on the inner body top (5b) and simultaneously rotating the inner body relative to the cam sleeve, the inner body can be further inserted into the cam sleeve until the horizontal beads (5f, 5f') on the inner body contact the cam sleeve top (4b) and the lugs of the holder cup enter the two spiral grooves (4c, 4c') of the cam sleeve. If the cam sleeve is not already inserted into the A-shell, this can be done by pressing down on the protrusion (5k) on the top (5b) of the inner body to drive the cam sleeve to a predetermined height within the A-shell, where the cam sleeve and A-shell can be glued together or crimped with a dot on the outside of the A-shell.If the inner body is scratched or otherwise damaged by forcing the holder cup (6) through the top (5b) of the inner body (5), the top (5b) of the inner body will sit under the top (3b) of the A-shell so that the holder cup (6) will not be visible in the fully assembled container (10).
[0023] Several methods of assembly are possible, each with its own advantages, and some examples of preferred methods are now described.
[0024] Example 1 - Assembly method 1. Assemble the cam sleeve (4) to the specified height inside the A shell (3). 2. Partially insert the bottom (5a) of the inner body (5) into the cam sleeve so that the flexible tabs (5j) of the inner body exert outward pressure against the inner surface (4f) of the cam sleeve and the horizontal slot extensions (5e, 5e') of the inner body remain exposed above the cam sleeve. 3. Assemble the holder cup (6) onto the top (5b) of the inner body (5) so that the holder cup sits in an extended position protruding from the top of the inner body, with the lugs (6c, 6c') of the holder cup seated in the horizontal slot extensions (5e, 5e') of the inner body. 4. Push down the protruding portion (5k) of the inner body until the horizontal beads (5f, 5f') of the inner body contact the top (4b) of the cam sleeve, and simultaneously rotate the inner body to fully insert the inner body into the cam sleeve, at which point the flexible tabs of the inner body extend outward below the bottom (4a) of the cam sleeve, the lugs of the holder cup enter the two spiral grooves (4c, 4c') of the cam sleeve, and the top (5b) of the inner body is below the top (3b) of the A-shell (3). 5. Insert the bottom (3a) of the A-shell and the bottom (5a) of the inner body into the base (2) so that the second set of gears (5i) of the inner body (5) mesh with the first set of gears (2i) of the base (2). 6. Optionally, rotate the base relative to the A-shell to lower the holder cup to its retracted position. 7. Optionally, a cap (1) is fitted onto the base to complete the container (10).

Insert the bottom part (5a) of the inner body into the top part (4b) of the cam sleeve, push down the protruding part (5k) of the inner body, and simultaneously rotate the inner body, while the lugs of the holder cup enter the two spiral grooves (4c, 4c') of the cam sleeve, until the horizontal beads (5f, 5f') of the inner body contact the top part (4b) of the cam sleeve and the flexible tabs (5j) of the inner body extend outward below the bottom part (4a) of the cam sleeve. At that point, the top part (5b) of the inner body is below the top part (3b) of the A-shell 3. 4. Insert the bottom (3a) of the A-shell and the bottom (5a) of the inner body into the base (2) so that the second set of gears (5i) of the inner body (5) mesh with the first set of gears (2i) of the base (2). 5. Optionally, rotate the base relative to the A-shell to lower the holder cup to its retracted position. 6. Optionally, a cap (1) is fitted onto the base to complete the container (10).
[0027] Variations of this method include the step of inserting the stick product (7) into the holder cup, which is performed before step 1, or between steps 1 and 2, or between steps 2 and 3, or between steps 3 and 4, or between steps 4 and 5.
[0028] Example 3 - Assembly Method 1.

Insert the holder cup (6) into the top (5b) of the inner body so that the holder cup sits in an extended position protruding from the top (5b) of the inner body with the lugs (6c, 6c') seated in the horizontal slot extensions (5e, 5e'). 3. Insert the inner body into the cam sleeve by pushing down the protruding portion of the inner body and simultaneously rotating the inner body until the horizontal beads (5f, 5f') of the inner body contact the top (4b) of the cam sleeve and the flexible tabs (5j) of the inner body extend outward below the bottom (4a) of the cam sleeve, while the lugs (6c, 6c') of the holder cup (6) enter the two spiral grooves (4c, 4c') of the cam sleeve. 4. Insert the cam sleeve (4) into the A shell (3) to a specified height so that the upper part (5b) of the inner body is below the upper part (3b) of the A shell (3). 5. Insert the bottom (3a) of the A-shell and the bottom (5a) of the inner body into the base (2) so that the second set of gears (5i) of the inner body (5) mesh with the first set of gears (2i) of the base (2). 6. Optionally, rotate the base relative to the A-shell to lower the holder cup to its retracted position. 7. Optionally, a cap (1) is fitted onto the base to complete the container (10).

[0030] The container for stick-shaped products according to the present invention utilizes an inner body that does not have any gaps around the top of the inner body, offering many advantages over conventional designs. For example, the top of the inner body does not need to be "opened" with a tool during pre-assembly of the holder cup and inner body, making the assembly process more efficient. The holder cup does not need to be retracted before assembling the inner body and cam sleeve. The holder cup may not need to be extended before product filling. Manufacturers can supply product fillers with the inner body / holder cup subassembly ready for filling. The container according to the present invention is more stable, as there is no or reduced rattle of the holder cup and stick-shaped product. Overall, the design of the present invention has an improved appearance, as there are no visible gaps or scratches.
