Description

DESCRIPTION

Container and lid with audible and tactile feedback

Field of the invention

The present invention relates to a container and a lid, wherein the lid produces an audible and tactile response when the container is closed with the lid. The invention further relates to a method of forming a lid that engages with a container.

Background of the invention

Containers with thread-fit lids are available in many different configurations, from those that simply have complementary threads to those that have different locking and / or locking features or configurations. Some containers have notches, fixings, snap fasteners and / or projections to secure the container to the lid. Additionally, these can sometimes provide a "click" or other sound to help the user know when the lid is sufficiently attached to the container or not attached to the container. Such a lidded container is shown in US 2008/0110850 A1. This container and lid are fastened together with threads, and the lid and container include a complementary notch and tab to provide an audible indication that the lid is sufficiently closed. These notches and tabs are located in a central position of the threads, separating the threads into segments. Another such container is disclosed in EP 2080711 A1, which provides a container for a fabric conditioning composition wherein the lid produces an audible sound when force is applied manually to interconnect the fasteners. It is stated that the closure may be a push-on, removable cap and could include threads with the interconnectable fasteners, which would preferably be an outward projection on an external surface of the dispensing opening and a corresponding downward-facing recess. inside onto an inner surface of the lid. These elements can provide audible and tactile feedback to the user.

Various configurations refer to the anti-unscrew characteristics for the lid and the container, including GB 2203729 A and WO 2016/016207 A1. GB 2203729 A provides a closure system for a container having separate tabs on the neck of a container for engagement, via the tabs, into a flap of a lid. In addition, the tabs on the neck also include a lip projecting into a space between the tabs on the cap, to prevent the cap from unscrewing. The tabs in the neck include a rectangular groove defined by the rim that receives a rod-shaped tab on the lid, when the lid is fully on the container. GB2203729 discloses a container and a lid according to the preamble of claim 1. WO 2016/016207 A1 provides a closure for a container with a screw thread on a neck of the container. At the end of the thread, a bearing surface is formed as a stop. A recess or interruption is provided in the screw thread of the neck, where a screw thread with an anti-unscrew formation can releasably engage. The anti-unscrew formation is shown and described as a progressively larger diameter thread with a portion where the thread segment is thicker in the vertical direction, in a region that forms a rectangular gradual expansion. While these anti-unscrew features would likely provide a tactile response to a user when opening or closing, no mention is made of an audible response.

Document US 4662530 refers to a stop device with an indexed closing position, for a bottle made of glass or other rigid substance.

Summary of the invention

However, there is a need for another type of container and lid, wherein the lid produces an audible and tactile response when the container is closed with the lid, and which allows a user to easily open and close the container. The present invention provides such another type of container and lid.

According to a first aspect of the invention, a container with a lid comprises a container neck surrounding an opening; at least one thread on the neck; at least one thread on the cap to engage the at least one thread on the neck; a protrusion at the bottom of the lid; an end stop at a lower end of the neck that stops further engagement between the at least one thread on the neck and the at least one thread on the cap; and a neck engaging portion corresponding to an area where the cap projection will engage the neck when the cap is in a fully engaged position; the socket portion comprising a recess adjacent the end stop for receiving and engaging the projection, and an inclined plane adjacent the recess leading into or out of the recess as the external diameter of the neck adjacent the recess increases, the socket portion arranged so that an audible response and a tactile response occur when the cap is moved to the fully engaged position. The fitting portion further comprises a increase in width of the at least one thread in the neck in the fitting portion. The recess and boss each have a rounded top portion.

In a second aspect, the present invention provides a method of forming a lid and a container neck to produce an audible and tactile response upon engagement and disengagement, the method comprising: producing a cap with at least one thread and one shoulder at the lower end; and producing a neck with at least one thread to engage the at least one thread on the cap, and an engaging portion with a recess to receive the projection, an end stop defining the recess, and an increase in the at least one thread of the neck and / or the outer diameter of the neck in the socket portion, wherein the socket portion and the protrusion are formed to produce a specific audible and tactile response when the cap is engaged or disengaged from the neck. Each of the recess and boss has a rounded top portion.

Such a lidded container can be clamped together and provide a user with audible and tactile feedback when the container lid is engaged or disengaged. This allows a user to know that a complete fit has taken place. Sensory feedback also helps the user to ensure a full fit every time, which is especially useful when the container contains spoilage-prone products if they are not properly sealed between uses, eg food products. Engagement of the boss with the end stop recess also allows for a secure fit and avoids excessive torque and thereby damage to the container or lid.

Increasing the width of said at least one neck thread in the engagement portion results in an increase in torque being required to move the projection through the portion leading to full engagement. This provides a user with the desired tactile response to know when full fit is achieved. The rounded upper portions in the recess and boss can aid in and out movement of the recess, to ensure smooth movements and that the torque required for engagement and disengagement is not so high that a average user had problems.

According to one embodiment, the recess extends vertically within the increase in width of the at least one thread on the neck in the engaging portion. Such a configuration can also produce the desired audible response when the lid is fully engaged and / or when it has been disengaged.

According to one embodiment, the inclined plane comprises an increase in the external diameter of the neck leading to the recess, and the engaging portion further comprises a further inclined plane leading from the recess to the increase in the thickness of the neck from of the inclined plane to facilitate the exit of the projection of the recess to disengage the lid from the container. This inclined plane can help ensure that the force required to disengage the lid from the container is not so great that a user cannot overcome it and disengage the lid to access the contents of the container. Such inclined planes can help provide tactile feedback to the user when the neck cap is attached or detached.

According to one embodiment, the audible and / or tactile response occurs in one or more of the following ways: engagement of the protrusion within the recess, stopping of the protrusion by the end stop, movement of the protrusion through the engaging portion or movement of the boss into or out of the recess. Depending on the embodiment, one or more of these functions produce a user specific audible and / or tactile response that has been shown to provide assurance to a user as to whether or not the lid has engaged with the container. One or more of these mechanisms can work together to form a system that not only produces audible and tactile feedback, but also secures the lid to the container.

According to one embodiment, the audible response produced comprises a muffled click when the lid is disengaged from the container and / or a fine click when the lid is moved to a fully engaged position. These sounds and tactile feedback have been shown to give users a positive indication that the container is fully closed or fully open. Additionally, users link this safety with the fact that the product inside the container is fresh and safe from external contamination.

According to one embodiment, the audible response has a frequency intensity in the range of about 0.00005-0.0036 watts per square meter (W / m2), preferably, from about 0.00005 to 0.003 W / m2, preferably from about 0.0001 to 0.002 W / m2. Engage and disengage have unique sound profiles and frequency histograms, respectively, which help the user feel and hear the engagement and disengagement process. Sound profiles and frequency intensity generated by engaging and disengaging have been shown to give test users confidence.

According to one embodiment, an increase in the width of the at least one thread in the neck in the engagement portion and / or the inclined plane increases the torque required to bring the cap to a fully engaged position. Depending on manufacturing techniques, seal requirements, content of the container, etc., different techniques can be used to produce the tactile response related to the fitting and unlocking of the lid. Two such techniques may consist of increasing the width of the thread and / or the neck in the socket portion.

According to one embodiment, the sound pressure level of the generated audible response is in the range of about 20 dB - 120 dB, preferably 30 to 100 dB, preferably 35 to 80 dB, preferably maximum 70 dB. This interval has been found to provide security for test users. Reference sound levels for audible response are generally from a distance of about 0.5 meters, or at arm's length.

According to one embodiment, the audible response has a duration of about 0.01 seconds or more, preferably 0.01 to 0.025 seconds, preferably 0.02 seconds. This duration of audible response has been found to provide assurance to the user that the lid has fully and properly engaged with the container, thereby assuring the user of the freshness of the contents of the container. According to one embodiment, the lidded container further comprises a plurality of projections and a plurality of engagement portions of the neck for engagement with the plurality of projections. A plurality of projections and a plurality of engaging portions can further ensure and produce the desired specific audible and tactile response when the neck cap is engaged and disengaged.

In accordance with a further aspect of the invention, a method of forming a lid and a container neck to produce an audible and tactile response to engagement and disengagement comprises producing a cap with at least one thread and a protrusion at a lower end; and producing a neck with at least one thread to engage the at least one thread on the cap, and an engaging portion with a recess to receive the projection, an end stop defining the recess, and an increase in the at least one thread of the neck and / or the outer diameter of the neck in the socket portion. The fitting portion and the protrusion are formed to produce a specific audible and tactile response when the cap is engaged or disengaged from the neck.

Such a container lid and neck include simple features that work together to ensure that they can be properly and securely nested and provide a user with a specific audible and tactile feedback, so that the user knows that they have been nested. or dislodged. The features also help prevent inadvertent disengagement and excessive torque, thereby protecting the seal and / or freshness of any product within the container.

According to one embodiment, the sound pressure level of the audible response is in the range of about 20 dB to 120 dB.

Figure 1A illustrates a perspective view of the container 10 with the neck 12, and Figure 1B illustrates a view in perspective of lid 14 to engage with the neck of container 10. Neck 12 may be integrally formed with a container, or it may be connected to a separate container.

Container 10 includes a neck 12 with an opening 13. Container 10 can be any type of container, but can be particularly useful for storing food products, and especially products that are opened and closed multiple times throughout their useful life.

The neck 12 includes the threads 20, the end stops 22, and the engaging portion 24 with the recess 26, the first inclined plane 28 and the second inclined plane 29. The threads 20 extend around an external surface of the neck 12. In In one embodiment, the recess 26 has a rectangular shape and the end stops 22 are formed from a generally vertical wall extending below the threads 20. The inclined planes 28 and 29 are formed by increasing the external diameter of the neck 12 which leads into and out of recesses 26. This is generally a gradual increase, although the slope and / or length may vary. The first inclined plane 28 may extend approximately 0.1-3mm and increase such that the external diameter at the high point of the inclined plane 28 is equal to the external diameter of the neck 12 on the threads 20, although it would typically be in the range lower than threads 30, for example 50% of the height of threads 30. The second inclined plane 29 is typically much shorter and steeper than the first inclined plane, although it may vary in different embodiments. The length and slope of inclined planes 28 and 29 can be used to help produce the specific audible and tactile response desired.

Although the material dimensions of container 10 and lid 14 may vary in different embodiments, an exemplary lid 14 and container 10 may be a lid 14 comprising polypropylene (PP) and a container 10 comprising polyethylene terephthalate. (PET). Container 10 may have a volume of about 600 grams, a neck diameter of about 83mm, and a thickness of at least 0.3mm. Cap 12 may have an outer diameter of approximately 88mm and a thickness of at least 1mm. These dimensions and materials can result in the sound profiles and frequency histograms shown in Figures 2A-2D and 4A-4D.

Cap 14 includes threads 30 and projections 32. Generally, the cap is cylindrical in shape on the outer side, and can be formed from a variety of materials. The cap preferably comprises polypropylene or high density polyethylene. The threads 30 extend around an internal surface of the cap 14, and the protrusions 32 are located on a bottom side of the cap, after the threads 30 terminate. In this embodiment, the protrusions 32 are trapezoidal in shape, although others embodiments could have protrusions 32 shaped differently to engage the recesses.

Cap 14 rotates to engage neck 12 so that threads 30 on cap 14 engage threads 20 on neck 12 to secure cap 14 to container 10. The engagement mechanisms are positioned so that the Protrusions 32 must pass over inclined planes 28 and engage recesses 26. Protrusions 32 and cap 14 are prevented from further engaging (and experiencing excessive torque) at that point by end stops 22. The displacement of the projections 32 on the inclined planes 28 provides a tactile response to users, increasing the torque required for the engagement of the cap 14, as the cap 14 approaches a fully engaged position. When the cap 14 and the projections 32 travel on the inclined planes 28 within the recesses 26, the audible response occurs, eg, in the form of a click.

Figures 2A-2D show sound profiles and frequency histograms for unlocking or opening (Figures 2A, 2B) and fitting or closing (Figures 2C and 2D) of the cover 14 with the neck 12. The audible click of the socket between cap 14 and neck 12 may be in the sound pressure level range of about 20 to 120 dB, preferably 30 to 100 dB, preferably 35 to 80 dB, preferably at most 70 dB, and lasts longer than 0.01 seconds, preferably at most 0.025 seconds, preferably at most 0.02 seconds, as shown in FIG. 2B. As shown in Figure 2D, the frequency intensity may be in the range of about 0.00005 to 0.0036 watts per square meter (W / m2), preferably from about 0.00005 to 0.003 W / m2, preferably from about 0.0001 to 0.002 W / m2. The cover 13 is prevented from turning further by the end stops 22 and the projections 32 rest in the recesses 26.

To disengage the lid 14 from the container 10, the protrusions 32 must be forced into the second inclined planes 29, producing additional audible and tactile feedback. The audible response at this offset is as shown in Figures 2A and 2D, and may consist, for example, of a muffled click shape, with similar ranges of 20 and 120 dB, intensity ranges of 0.0001 - 0 .0036 and a duration of 0.01 seconds or more.

As mentioned in the background, some prior art lids and containers have engaging features in the form of notches and tabs or interlocking fasteners that can provide audible and / or tactile feedback. The present invention, however, utilizes a combination of specific features on the cap and neck, including a protrusion at a lower end of the cap, a a neck recess, an end stop, and an incline work together to produce specific audible and tactile feedback ensuring proper fit or disengagement for a user. These features also work in conjunction to secure the lid 14 to the container 10 and prevent overturning. As in the embodiment shown, additional inclined planes and / or thickness of the threads or neck may also be used to contribute to the desired specific audible and / or tactile response.

The use of the snap features on the cap 14 and neck 12 work together to secure the cap 14 to the neck 12 and provide audible and tactile feedback to the user. The projections 32 provide a sensory response as they travel on inclined planes 28 and 29 into or out of recess 26. The specific audible interval produced, duration, and frequency intensity intervals have been found to display histograms of frequency and unique sound profiles. These specific unique frequency histograms and sound profiles have been shown to assist a user in knowing when the lid 14 has been engaged or disengaged and thus to be confident of the freshness of the contents of the container.

Sensory feedback, including audible and tactile, helps a user know that lid 14 is properly engaged with container 10, thereby ensuring the actual seal of container 10 and the freshness of the contents therein. Additionally, the inclined plane 28 leading up to the recess 26 can help the user feel when the lid 14 approaches full engagement with the container 10, and the fit in the recess 26 provides the user with a specific response that the lid 14 is fully engaged. In addition, these features provide the user with an audible and tactile response to disengagement of lid 14 from container 10, thereby ensuring that a user knows that container 10 and lid 14 are fully engaged and protecting the freshness of container contents. 10 between uses. The sloping sides of the trapezoidal protrusions 32 (and inclined planes 28 and 29) can help allow the protrusions 32 to enter and exit the recess 26 without too much effort on the part of the user, ensuring that even weaker users can snap in and out the lid 14 with the neck 12 of the container 10. The recesses 26 with the end stops 22 also help to minimize play between the lid 14 and the container 10 when fully engaged, thereby helping to prevent any loosening or unscrewing of the cap 14 neck 12.

Figure 3A illustrates a perspective view of a second embodiment of a container neck 12, and Figure 3B illustrates a perspective view of a cap 14 for engaging the container neck 12. Similar parts are marked similarly to Figures 1A to 1B. Figure 4A shows a sound profile and Figure 4C shows a frequency histogram of the disengagement (opening) of the neck cap 14 12. Figure 4B shows a sound profile and Figure 4D shows a frequency histogram of the engagement (closing) of cap 14 with neck 12.

The neck 12 includes the threads 20, the end stop 22 and the mating portion 24 with the recess 26, the inclined plane 29 and the widened thread 34. The threads 20 extend around an outer surface of the neck 12, and increase in width in the area of engagement leading to the recess 26. In this embodiment, the recess 26 has a rounded top portion, which extends into the thread 34 flared, and the end stops 22 are formed from a wall extending below the threads 20 that define the recess 26. The inclined plane 29 is formed by increasing an outer diameter of the neck 12 exiting the recesses 26. Inclined plane 29 is normally quite short and steep, although it may vary in different embodiments, and some embodiments may not include inclined plane 29.

Cap 14 includes threads 30 and projections 32. Threads 30 extend around an internal surface of cap 14, and projections 32 are located at a lower end of the cap, after the threads 30 have ended. In this embodiment, the projections 32 have a rounded top portion to correspond to the shape of the recess 26, although other embodiments could have projections 32 (and recesses 26) with different shapes for engagement.

Cap 14 engages neck 12 in roughly the same manner as the embodiment shown in Figures 1A-1B, rotating around neck 12 so that threads 30 engage threads 20. When approaching a fully position nested, additional torque is required due to the widened threads 34. When protrusion 32 engages recess 26, there is an audible response, eg, a precise click. This may be in the sound pressure level range of about 20 to 120 dB, preferably 30 to 100 dB, preferably 35 to 80 dB, preferably at most 70 dB, with a frequency intensity of about 0.00005 to 0 0.0036 watts per square meter (W / m2), preferably from about 0.00005 to 0.003 W / m2, preferably from about 0.0001 to 0.002 W / m2, and a duration of about 0.01 seconds or more, for example , from 0.01 seconds to about 0.025 seconds, or from about 0.02 seconds (see Figures 4B, 4D). These specific ranges have been found to provide security for users.

When the cap 14 is disengaged from the neck 12, the inclined plane 29 and / or the shape of the projection 32 can help to smooth the disengagement of the projection 32 with the recess 26 and the reengagement of the projection 32 with the threads 20. The response occurs audible and tactile through disengagement or opening, and may be, for example, a muffled click produced when projection 32 moves out of the recess. This can at least partially result from deflection of the boss 32 and / or the cap 14 in displacement. The audible response may be in the range of approximately 20 to 120 dB, preferably 30 to 100 dB, preferably 35 to 80 dB, preferably maximum 70 dB, with a duration of approximately 0.01 seconds or more, preferably maximum 0.025 seconds, preferably at most 0.02 seconds and a frequency intensity of about 0.00005 to 0.0036 watts per square meter (W / m2), preferably from about 0.00005 to 0.002 W / m2, preferably from about 0 .0001 to 0.001 W / m2 (see Figures 4A, 4C).

A user-specific tactile and audible feedback can be provided by using the protrusion 32 at the lower end of the cap 14 to engage it with a complementary shaped recess 26 and the widened threads 34 leading to recess 26, cap 14 and neck 12. The flared threads 34 require additional torque to displace the through boss 32, and displacement of the boss 32 past the flared threads 34 within the recess 26 produces an audible sound. The torque range can be, for example, 0.5 to 8 N.m. End stop 22 and widened thread portion 34 help to hold boss 32 within recess 26, thereby helping to secure cap 14 to neck 12 and prevent any unscrewing. The shapes of recess 26, protrusion 32, and the engaging portion leading to recess 26 all work together to produce the specific audible and tactile response desired for a user, as well as to allow a user to be able to engage and disengage. cap 14 from neck 12 without too much effort. The end stop 22 helps prevent excessive torque from occurring and thus damage to the seal that can occur between proper fit of cap 14 and neck 12.

In summary, by providing at least one protrusion on a bottom portion of the lid 14 that can interact with the snap features (including a recess 26 and an end stop 22) on the neck 12 of a container, the container 10 and the lid 14 can provide a secure connection and user-specific audible and tactile feedback to indicate a complete fit. This can help a user feel more confident about the freshness of the product within the container 10 when they receive this specific audible and tactile response to disengagement, as well as ensure that the user properly fits the cap 14 with the neck 12 afterwards. each use by rotating until audible and tactile feedback occurs. Said sensory response produced is of a duration and / or frequency intensity range such that an average user feels confident that the lid is properly closed and that the container will keep the product safe from external contamination.

These features can be especially useful for containers 10 to be stored and / or transported and thereby ensuring the freshness of any product in container 10.

While neck 12 and cap 14 have been shown with various threads 20 and 30 and various mating features (protrusions 32, recesses 26, etc.), these amounts and locations are for example purposes only and could be different at different times. accomplishments. Neck 12 and cap 14 have at least one protrusion 32 to engage a recess 26 with an end stop 22, which provides audible and tactile feedback through engagement. Similarly, the description and ranges for the length, intensity, and frequency of the full socket audible response is for example purposes only, and ranges may vary depending on the materials used, the thickness of the annular features of fit, the profile / design of the fit characteristics, the material distribution, the contents of the container 10, the configuration of the neck 14 and the lid 12, etc. However, the intervals provided have been shown to be particularly useful for a wide range of users in providing a desired audible and tactile response, without being overwhelming for a user.

Some specific examples of containers 10 and lids 14 that could be used to produce the desired audible and tactile response for a user include containers 10 made of PET and lids 14 formed of PP having the following dimensions:

Although these specific examples are provided, other containers and lids could produce the desired audible and tactile response, and this application is not limited to the specific example dimensions provided above.

Although the invention has been described with reference to exemplary embodiments, those skilled in the art will understand that various changes can be made and that elements thereof can be substituted for equivalents without departing from the scope of the invention. Additionally, many modifications can be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope of the invention.
