Description

Strip package

Technical Field

The present invention relates to a strip package with a lateral press actuator or end press actuator, in particular for containing a cosmetic product.

Background

Several types of stick packs are currently available for containing a cosmetic product, such as a lipstick tube for containing lipstick.

One more basic type of lipstick tube has a rotatable housing. To use the lipstick, the user must rotate the housing to eject the lipstick and then reversely rotate the housing to retract the lipstick. The handling of this type of lipstick tube is not convenient for the user. Control of the amount of lipstick pushed out is difficult or even impossible. In such a case, the user often pushes out an excessive amount of lipstick, and thus it cannot maintain hygiene.

Lipstick tubes using push buttons have also been developed. With such a lipstick tube, the lipstick can be pushed out by only a slight movement, such as a tap, and there is no longer a need to retract the lipstick.

EP 2604142 a1 discloses a knock-on dispensing container comprising a knock-on body, a thrust element, a piston rod and a non-return element. When the user taps the knocking body, the cam surface of the knocking body can be in sliding contact with the cam surface of the propelling component, and therefore the propelling component is pushed. The pushing teeth of the pushing member are engaged with the locking portion of the piston rod, whereby the piston rod is pushed forward, and thereby the medium is pushed out. The locking portion slides over the non-return claws of the non-return member and is then locked by these non-return claws.

US 7,217,054B 2 discloses a lateral tapping type delivery mechanism, wherein a tapping button is pressed to rotate a rotary member. The ratchet teeth of the rotating member engage with the saw teeth of the cylinder and thereby rotate. This rotational movement is finally converted into an axial movement of the piston rod by means of the threaded engagement.

EP 1672992B 1 discloses a lipstick package which utilizes resilient lugs to rotate a nut plate to axially move a screw by threaded engagement or a pawl to axially move a screw by a ratchet and pawl mechanism.

The pawl, ratchet and resilient projection are all part of a ratchet-pawl mechanism, which is an impact mechanism whose durability is unsatisfactory. Furthermore, the structures known today comprise a large number of component parts, which also means that they are necessarily relatively complex and expensive, and have a low reliability.

Detailed Description

Fig. 1A and 1B show a strip pack 10 according to a first embodiment of the invention in an end view and a side view, respectively. Fig. 2 and 3 show cross-sectional views of the a-a cross-section and the B-B cross-section in fig. 1A, respectively.

As shown, the strip pack 10 includes a base 220 and two

end caps

210, 230. The base 220 is provided with an actuator 600. The actuator 600 can be pressed and can reciprocate through the through-hole 221 of the base 220.

Fig. 4 shows the strip package 10 in exploded view, the base 220 being fixedly provided with a first inner shell 310 and a second inner shell 320 in its interior. It will be appreciated that the two inner shells may also be integrally formed as part of the base 220.

The upper side of fig. 4 shows the movement mechanism of the strip package 10, which comprises the cup holder 400, the driving member 500, the actuating member 600, the rotation mechanism 700 and the spring 800. The motion mechanism is basically assembled into the base 220.

As shown, cup holder 400 includes a cup portion 410 that contains the contents and a screw 420. The external threads 42d of the screw 420 engage with the internal threads 71d (shown in fig. 2 and 3) of the rotary mechanism 700 so that the cup holder 400 moves axially with rotation of the rotary mechanism 700. In the assembled state, the cup portion 410 of the cup holder 400 is placed in the first inner housing 310, and the screw 420 penetrates through the end hole of the first inner housing 310.

The external thread 42d is not provided throughout 360 ° in the circumferential direction of the screw 420. As shown in fig. 4, the screw 420 has a flat portion (or flat surface) 42 e. The inner shell 310 is also provided with a corresponding flat 31 e. In the assembled state, the flat 42e of the screw 420 is in contact with the flat 31e of the inner housing 310, and since the inner housing 310 is fixed relative to the base 220, this contact between the

flats

42e and 31e prevents relative rotation between the screw 420 and the inner housing 310 while allowing axial sliding of the screw 420 relative to the inner housing 310. It will be appreciated that other arrangements than flats are possible, such as complementary shaped axial (or longitudinal) grooves and protrusions on the screw 420 and inner housing 310, respectively, so long as relative rotation between the screw 420 and inner housing 310 is prevented and relative sliding between them is permitted.

The actuator 600 is for example provided in the form of a button which can be pressed through the through hole 221 in the base 220 and can be returned to its original position through the through hole 221. The actuator 600 has a ramp 60 a.

The driver 500 has a ramp 51a, which ramp 51a is in constant slidable contact with the ramp 60a of the actuator 600. By virtue of this contact, the actuator 600, when depressed, will urge the driver 500 in an axial direction (e.g., to the right as shown) of the strip package 10. The driver 500 further has a plurality of pushing portions 521, each pushing portion 521 having an inclined end surface 52b and a stopper portion 52f at an end opposite to the inclined surface 51 a.

The rotary mechanism 700 includes a drive ring 720 and a drive shaft 710 having a generally cylindrical body inserted into the drive ring 720. The drive shaft 710 and the drive ring 720 are provided with

flat portions

71c, 72c, respectively, which contact each other. The contact between the

flat portions

71c, 72c allows the drive shaft 710 to rotate with the drive ring 720 and allows axial relative sliding between the drive shaft 710 and the drive ring 720. It will be appreciated that the drive shaft 710 and drive ring 720 may be provided with other forms than flat portions, so long as relative rotation between the drive shaft 710 and drive ring 720 is prevented and relative sliding is permitted.

The drive shaft 710 is provided with internal threads 71d (shown in fig. 2 and 3) that engage the external threads 42d of the screw 420. The drive ring 720 is provided with a projection 721, the projection 721 having an inclined end surface 72b at an end facing the driver 500. The inclined end surface 72b of the rotation mechanism 700 slidably contacts the inclined end surface 52b of the driver 500.

The spring 800 abuts a flat end of the drive ring 720 at one end and the second inner housing 320 at the other end.

In the assembled state, the cup holder 400, the driver 500, the actuator 600, the rotation mechanism 700, and the spring 800 are all coaxially arranged. The screw 420 of the cup holder 400 is inserted in the drive shaft 710 of the rotating mechanism 700; the drive shaft 710 is inserted in turn in the drive member 500; both ends of the driving member 500 are slidably contacted with the actuating member 600 and the driving ring 720 of the rotating mechanism 700, respectively; the other end of drive ring 720 opposite drive member 500 is biased by spring 800.

Fig. 6 shows a cross-sectional view of the base 220. The base 220 is provided on its inner wall with a plurality of longitudinally extending inner protrusions 222, and inner grooves 223 between adjacent inner protrusions 222. In the present embodiment, each of the inner protrusions 222 has one inclined end portion 22 b.

In the assembled state, the movement mechanism shown in fig. 5 is arranged in the base 220. The push portions 521 of the driver 500 are each located in the inner groove 223 of the base 220, and the protrusions 721 of the drive ring 720 of the rotating mechanism 700 are also located in the inner groove 223 of the base 220. Due to the bias of the spring 800 and the inclined surface contact between the projection 721 and the pushing part 521, the projection 721 tends to rotate in the direction indicated by the arrow R1 in fig. 5. However, the projection 721 remains stationary in a balanced state due to being caught in the inner groove 223 of the base 220.

The operation of the movement mechanism is described below with reference to fig. 5 and 6.

Before the actuator 600 is depressed, the various components of the motion mechanism are in their respective initial positions.

When the actuator 600 is pressed, the inclined surface 60a and the inclined surface 51a of the driving member 500 slide relatively, and the driving member 500 is pushed to the right. The driving member 500 moving rightward causes the driving ring 720 of the rotating mechanism 700 to overcome the biasing force of the spring 800 and pushes the convex portion 721 of the driving ring 720 out of the inner groove 223 of the base 220. When pushed out of the inner groove 223, the drive ring 720 is rotated in the direction indicated by the arrow R1 in fig. 5 due to the contact of the inclined surfaces, while the convex portions 721 slide along the inclined end surfaces 52b of the push portions 521 and the inclined end portions 22b of the inner projections 222 of the base 220 until stopped by the stopper portions 52f of the push portions 521 of the driver 500.

The above-described rotation of the drive ring 720 rotates the drive shaft 710, that is, the rotation mechanism 700 rotates in the R1 direction as a whole. Because the screw 420 is axially slidable and non-rotatable, rotation of the rotation mechanism 700 causes the screw 420 to translate axially by virtue of the threaded engagement between the drive shaft 710 and the screw 420. Thereby, screw 420 pushes cup portion 410 of cup holder 400 outwardly a predetermined distance along with the contents contained therein.

When the force pressing the actuator 600 is removed, the spring 800 returns to its original position and pushes the drive ring 720 in the axial direction. The convex portion 721 of the drive ring 720 urged by the spring force slides along the inclined end portion 22b of the inner protrusion 222 of the base 220, so that the drive ring 720 continues to rotate in the R1 direction. At this time, since the stopper 52f of the push portion 521 is also in the form of an inclined surface, and the push portion 521 can only slide in the inner groove 223 of the base 220 without rotating, the protrusion 721 of the rotating drive ring 720 slides over and passes over the stopper 52f to continue sliding into contact with the inclined end surface 52b of the push portion 521, and then the driver 500 is retracted to its initial position by pushing the push portion 521. At the same time, by virtue of the threaded engagement between the drive shaft 710 and the screw 420, rotation of the rotary mechanism 700 in the direction R1 continues to advance the cup holder 400 outwardly a predetermined distance. In this process, the axially translated driver 500 pushes the actuator 600 to its initial position.

As shown in fig. 2 and 3, the strip package 10 may also be provided with an applicator 20 therein, which may be accommodated in the second inner case 320.

Fig. 7 shows a strip package 30 according to a second embodiment of the present invention. As shown, the strip pack 30 includes a base 3220 and an end cap 3210. The base 3220 is provided with an actuator 3600 at its end opposite the end cap 3210. The actuator 3600 can be depressed and can reciprocate through an end through hole of the base 3220.

The base 3220 includes an inner shell 3310 disposed within the interior thereof, the inner shell 3310 being provided with internal threads 3311. It is understood that the base 3220 and the inner shell 3310 may also be integrally formed. Similar to the base 220 in the first embodiment shown in fig. 6, the base 3220 is also provided with a plurality of longitudinally extending internal protrusions 3222 on its inner wall, and internal grooves 3223 between adjacent internal protrusions, as shown in fig. 8 and 9. Each of the inner protrusions 3222 has an inclined end 322 b.

The movement mechanism of the strip pack 30 comprises a cup-shaped holder 3400, a driving member 3500, an actuating member 3600, a rotation mechanism 3700, and a spring 3800. The motion mechanism is basically assembled into base 3220.

Here, the cup-shaped holder 3400 is substantially the same as that of the first embodiment, and also includes a cup-shaped portion 3410 for containing contents and a screw 3420. The screw 420 also has an external thread 342d and a flat portion (or flat surface) 342 e.

Drive member 3500 end is in direct contact with actuator 3600 and is not in contact with an inclined surface as in the first embodiment. Similar to base 220 in the first embodiment shown in FIG. 6, drive member 3500 further has a plurality of pushers 3501, as shown in FIGS. 8 and 9, each pusher 3501 having an angled end surface 350b and a stop 350f at an end opposite actuator 3600. The inclined end surface 350b and the stopper 350f meet at a tip straight line.

Actuator 3600 can reciprocate axially through one end of base 3220 and can push drive 3500 in an axial direction. In addition to not having a ramped surface, the actuator 3600 also differs somewhat from the overall shape of the actuator 600 in the first embodiment, however it will be appreciated that the actuator can be provided with any suitable overall shape.

Unlike the first embodiment, the rotating mechanism 3700 does not include a drive shaft, nor is it provided with internal threads, but is merely in the form of a drive ring. This drive ring is substantially the same as the drive ring 720 in the first embodiment. As shown in fig. 8 and 9, the rotating mechanism 3700 is provided with a projection 3701, and the projection 3701 has an inclined end surface 370b at an end facing the driving member 3500. Angled end surface 370b of rotation mechanism 3700 is in slidable contact with angled end surface 350b of drive member 3500.

The rotating mechanism 3700 is provided with a flat portion 370e inside. Screw 3420 of cup holder 3400 is disposed through rotary mechanism 3700. Thereby, flat portions 370e of rotating mechanism 3700 are engaged with flat portions 342e of screw 3420 of cup holder 3400, so that cup holder 3400 can rotate with the rotation of rotating mechanism 3700 and cup holder 3400 can rotate relative thereto in rotating mechanism 3700.

In the assembled state, the movement mechanism of the stick pack 30 is arranged in the base 3220. The push portions 3501 of drive member 3500 are each positioned in an interior slot 3223 of base portion 3220, and the projection 3701 of rotation mechanism 3700 is also positioned in an interior slot 3223 of base portion 3220. Due to the biasing of the spring 3800 and the inclined surface contact between the projection 3701 and the pusher 3501, the projection 3701 tends to rotate in the direction indicated by the arrow R3 in fig. 9. However, the projection 3701 remains stationary in a balanced state due to being caught in the inner groove 3223 of the base 3220.

The operation of the movement mechanism of the strip pack 30 will be described with reference to fig. 7 to 9.

Before actuator 3600 is depressed, the components in the kinematic mechanism are in their respective initial positions.

When actuator 3600 is depressed, it directly urges drive member 3500 to move axially (e.g., to the left as shown). Drive member 3500 continues to move axially so as to push projections 3701 of rotation mechanism 3700 out of interior slots 3223 of base portion 3220. As the restraint of inner slot 3223 is released, rotary mechanism 3700 rotates in the direction shown by arrow R3 in fig. 9 and slides over angled end surface 350b of drive member 3500 and angled end portion 322b of inner projection 3222 of base portion 3220 in sequence until projection 3701 of rotary mechanism 3700 is blocked by blocking portion 350f of drive member 3500.

Upon rotation of the rotation mechanism 3700, the rotation mechanism 3700 brings the screw 3420 and thus the cup-shaped holder 3400 to rotate together due to the contact between the

flat portions

342e and 370 e. Due to the threaded engagement between inner housing 3310 of base 3220 and screw 3420 of cup holder 3400, and due to the stationary state of inner housing 3310, screw 3420 has to be advanced axially forward (e.g., to the left as shown) while rotating. Thereby, cup 3410 and the contents contained therein are pushed out.

When the pressing force applied at the end of actuating member 3600 is released, tab 3701 of rotational mechanism 3700 continues to rotationally slide in the direction R3 over angled end 322b of inner protrusion 3222 of base 3220 and over and beyond stop 350f of driver 3500 under the biasing force of spring 3800. Then, projection 3701 of rotation mechanism 3700 slides into inner slot 3223 of base 3220, pushing drive member 3500 back to its initial position. It will be appreciated that this continued rotation of rotation mechanism 3700 causes screw 3420 and cup holder 3400 to continue to rotate and advance a predetermined distance.

According to the first and second embodiments of the present invention, strip packs in the form of side presses and end presses are provided, the movement mechanisms of which are slightly different. It will be appreciated, however, that those skilled in the art, given the teachings of this application, will be able to make certain adjustments to the motion mechanism so that the form of side and end presses can be implemented in any combination with the various motion mechanisms of the two embodiments. Such modifications are intended to fall within the scope of the claimed invention.

Fig. 10 shows a strip package 40 according to a third embodiment of the present invention. As shown, the strip pack 40 includes a base portion 4220 and an end cap 4210. The base portion 4220 is provided with an actuator 4600. The actuator 4600 can be pressed and can reciprocate through a through hole in the base portion 4220.

Fig. 11-13 illustrate the internal structure of the strip pack 40 with the base 4220 and end cap 4210 removed. As shown, the strip pack 40 is internally provided with a driving member 4500, a non-return member 4700, a spring 4800, and a cup holder. Cup holder includes cup portion 4410 and push rod 4420 disposed through drive member 4500 and non-return member 4700.

The push rod 4420 has a plurality of teeth 4421, each tooth 4421 having an inclined tapered slope at a front side thereof. Drive member 4500 and non-return member 4700 each have a pawl 4501, 4701 adapted to engage teeth 4421 of push rod 4420.

The actuation member 4600 includes an actuation body 4610, a push rod 4620, and a hinge 4630. The hinge 4630 connects the actuation body 4610 and the push rod 4620, and the push rod 4620 is rotatable about the hinge 4630. Preferably, the hinge 4630 is elastic. The hinge 4630 is made of, for example, a thermoplastic elastomer.

The push rod 4620 has a rounded portion 4621 and a flat portion 4622 at one end, the flat portion 4622 abutting against the flat portion 4611 of the actuating body 4610. The push rod 4620 has a front end 4623 at the other end, the front end 4623 being slidably and rotatably received in the recess 4503 of the drive 4500. Preferably, the front end 4623 of the push rod 4620 has a rounded shape, and more preferably, the recess 4503 of the drive member 4500 has a complementary shape to the front end 4623 of the push rod 4620.

The operation of the movement mechanism of the strip pack 40 will be described with reference to fig. 11 to 13.

When the actuation member 4600 is pressed downward, the actuation body 4610 translates downward and the push rod 4620 rotates relative to the actuation body 4610 about the hinge 4630 while the front end 4623 of the push rod 4620 advances forward to push the drive member 4500 forward against the spring force of the spring 4800. With the downward translation of the actuation member 4600, the flat 4622 of the push rod 4620 slides over the flat 4611 of the actuation body 4610, eventually the rounded 4621 of the push rod 4620 abuts the flat 4611 of the actuation body 4610 and the push rod 4620 is in a horizontal state.

During the driving member 4500 is pushed forward, the pawl 4501 of the driving member 4500 pushes the push rod 4420 forward through the tooth 4421 of the push rod 4420. At this time, since the check member 4700 is fixed with respect to the base portion 4220 of the strip pack 40, the teeth 4421 of the push rod 4420 moving forward deforms and expands the ratchet 4701 of the check member 4700. After the tooth 4421 passes the detent 4701, the detent 4701 of the check member 4700 is folded back and restored to its original shape, and engages the next tooth 4421 of the push rod 4420.

When the pressing force on the actuator 4600 is released, the elastic force of the spring 4800 pushes the driving member 4500 rearward. Push rod 4420 cannot move rearward due to the engagement of check member 4700. In this case, the pawl 4501 of the driver 4500 moving backward is deformed to expand and pass over the tooth 4421 of the push rod 4420, thereby engaging the next tooth 4421 of the push rod 4420. At the same time, the rearward moving drive 4500 pushes the push rod 4620 rearward through the front end 4623 of the push rod 4620. Thereby, the push rod 4620 counter-rotates about the hinge 4630 with respect to the actuating body 4610 and pushes the actuating body 4610 to translate upward until it returns to the initial position.

A third embodiment of the present invention proposes a novel actuator 4600. It is understood that the actuator 4600 can also be applied to the first and second embodiments of the present application. In this case, the

drive members

500, 3500 of the first and second embodiments may no longer be provided with an

inclined end surface

52b, 350b, but with a recess 4503 similar to that described in the third embodiment for receiving the front end of the push rod of the actuator member.

According to a third embodiment of the present invention, the actuation member 4600 includes an actuation body 4610, a push rod 4620, and a hinge 4630. It is however understood that the hinge 4630 may even be omitted, as long as the push rod is arranged obliquely between said actuating body and said driver, so that a translational movement of the actuating body perpendicular to the longitudinal direction of the strip-shaped package and a translational movement of the driver parallel to the longitudinal direction of the strip-shaped package can be mutually converted. For example, the actuating body 4610 may be provided with a recess to receive a rear end of the push rod 4620 opposite the front end 4623.

With the novel actuator 4600 according to the present invention, the user's push stroke can be significantly longer than the desired content overhang. Since the required content overhang is usually small, lengthening the pressing stroke allows the user to obtain a good feel when pressing and a clear feedback when releasing the actuator. Additionally, different ratios of pressing stroke and content protrusion may be achieved by adjusting the shape and angle of the push rod 4620 relative to the actuating body 4610 during design and manufacturing.

Referring to fig. 10 and 11, the strip pack 40 has a cross section like a shape of a water droplet as a whole. The end cap 4210 also has an angled end surface 4211 and a convex portion (or tip) 4212. In this case, the lipstick 50 contained in the bar package 40 may have a corresponding inclined end surface 51 and a convex portion (or tip) 52. The lipstick having a novel shape allows a user to precisely and easily apply the lipstick to a small area of the lips. It will be appreciated that the cross-section of the strip-shaped package may also be provided with at least one convex and be, for example, triangular, heart-shaped, spindle-shaped, etc.

In the stick pack of the present invention, the cup-shaped portion may contain, for example, a cosmetic product in solid form, such as a lipstick. In addition, the cup-shaped portion can also be configured to contain liquid contents. In this case, the strip pack further comprises an end member provided with one or more openings through which the contents are discharged.

The present invention has been described above with reference to embodiments, but it should be noted that the above-described embodiments are exemplary rather than limiting. The individual features described in the above-described embodiments can be combined and used in different embodiments as desired without conflicting with each other. And those skilled in the art will recognize that many changes may be made thereto without departing from the spirit and scope of the present invention, which is intended to be covered thereby.
