Description

A kind of sealing

It is 60/058 that the application requires application number, 296 applyings date were the interests of the U.S. Provisional Application on September 9th, 1997, and it is extendible portion in January, 1998 application such as Mohary on the 21st, its application number is (Attomey Dkt.No.JBP 419), exercise question is " dispense container ", and these two pieces of integral body are joined together the reference as the application.

The present invention relates to the field of container closure, especially the taper field of sealing.

The present most of container that uses all is to be that the adult uses design-calculated, and child's hand is less, and therefore, they are difficult to hold and extrude content from using the design-calculated container for being grown up.On the contrary, the adult is difficult to use those to use specially designed dispense container as the child.

Another relevant issues of relevant conventional container are, these containers are designed by the adult, are used to discharge content, and the strength of promptly extruding the size of the required power of content and adult staff from container is suitable.Children and aged people, a little less than most of adult, children and the old man more weak than the adult do not extrude the required strength of content.Therefore, the people little for those hand strength can use container better, wish container to extrude power less.

In the packing of existing toilet articles, content is often deposited with vertical direction, for example, the closed end of container be located at open end below, be the deposit position that is full of content in the container at this moment.When content is placed with vertical direction, need extrude content from container with inverted orientation usually.Container has certain capacity usually, for example, because content contacts with wall of container, is not easy to extruding of content.Capacity in the container is emphasized that content is deposited with vertical position and is used with opposite direction.What this problem was emphasized in addition is under the situation of the content of depositing thickness such as shampoo, extrudes inconvenience.

Another problem of conventional container is, they can landing from hand, and are all the more so when especially hand is wet.For the toilet articles that generally is used to have a bath by children, for example the container of shampoo and body lotion etc. is a special problem.

A kind of that be particularly suitable for the reverse package container and have a stable platform to seal design be exactly that taper is sealed.Yet, because these geometric configuratioies of sealing make that their manufacturing is very difficult.Especially must stop the longer time so that cool off fully in its thickest zone in its mold when these seal, if perhaps take out from mold prematurely, these often seal and also form fitfull " recessed " or pit at its outside face.

Therefore, an object of the present invention is to provide a kind of dispense container, this container is designed to all can cosily use in children and adult hand.

Another object of the present invention provides a kind of container, and this container only needs less power to discharge content from container, thereby makes those glad uses of people of strength deficiency on hand.

Another purpose of the present invention provides a kind ofly has design feature for preventing container landing from hand, especially the container of landing when hand is wet.

Another purpose of the present invention provide a kind of in the container content capacity when depositing the liquid contents of thickness, can stablize the container of placement at reversed position more after a little while.

A present invention also purpose provides a kind of use to children and adult and has the human engineering effect vessel surface can labelled easily container simultaneously.

A further object of the present invention provides a kind of taper with minimal surface defective and seals, and makes to include this container that seals and can be inverted and deposit.

According to the present invention, provide a kind of taper to seal, this sealing comprises, and/or comprises substantially:

A) periphery is sealed sidewall, and this sidewall comprises and seal sidewall and lower sealing sidewall on one, seals sidewall on wherein and comprises that also one has the end face of periphery, and the lower sealing sidewall comprises that also one has the bottom surface of periphery;

B) platform seals sidewall with periphery and becomes one with one heart, and has one from the recessed upper mounting plate surface of end face.

Obtain a taper by another aspect of the present invention and seal, this sealing comprises:

Derive a taper by another aspect of the present invention and seal, this sealing comprises:

B) platform seals sidewall with periphery and becomes one with one heart;

C) groove, being positioned at that platform and periphery seal in the middle of the sidewall and seal sidewall with platform and periphery is one.

Derive a kind of manufacturing method for sealing on the one hand again by of the present invention, this method comprises:

Seal being enough in mold to form the condition lower mould of sealing, comprising:

B) platform seals sidewall with periphery and becomes one with one heart, and a upper mounting plate surface is arranged;

Because the feature of the uniqueness that is had is sealed in taper of the present invention, make the production cycle that has the percentage of surface " pit " or surface deficiency and seal all significantly reduce.

In this article, term " vertical direction " is meant that the closed end of container is positioned under the nose end of container, i.e. state when being full of by content that adorned in the container and container is placed on the appropriate location.On the contrary, term " handstand direction " is meant that the closed end of container is positioned on the nose end.Similarly, term " side direction " is meant to hold and is in the direction upright and midway location that stands upside down.The explanation of this direction is the direction of container for convenience of explanation only, does not hint depositing and the direction of container from wherein discharge the content process.As described below, the various embodiment of the present invention's container all can uprightly or stand upside down and use.

Base model of the present invention and 6 is represented by numeral shown in Figure 1A, Figure 1B and Fig. 1 C.Container 6 comprises a nose end 1 and a closed end 2.The closed end 2 of container 6 preferably has a surface 21, and when container 6 uprightly was positioned on the plane, this surface made container keep motionless.The nose end of container 6 comprises a neck 3, and this neck 3 forms a hole 20 on container.This neck comprise one with the eck part 4 that (not shown) cooperates of sealing of container.Eck shown in Figure 1A and the 1B partly is the screw thread eck, but any other known eck mode all can be used in the container of the present invention.Give an example in passing, other eck that is fit to comprises, is pressed into the cooperation eck, the snap-on eck, pressing is also rotated eck, or the screw thread eck, but be not limited only to these ecks, for example John Wiley and Sons were in the disclosed eck type of Wiley Packaging Engineering cyc in the New York publication in 1986.

The nose end 1 of container 6 also comprises a shoulder 5, is used for neck 3 is connected to the housing 22 of container.The housing 22 of container comprises the upper casing part 7 of a contiguous nose end 1, and its cross-sectional plane is preferably columnar.The upper casing part 7 of container 6 preferably has a girth, and the edge is measured perpendicular to container 6 longitudinal axis 23,4.7 inches to 6.0 inches of its model Zhou Congyue, and situation is from about 5.0 inches to 5.7 inches preferably, preferably from 5.2 inches to 5.7 inches.Upper casing part 7 is along being preferably a substantially invariable girth at least on the length of 0.2 inch of container 6 longitudinal axis.

Shown in Figure 1A, upper casing part 7 carries out the transition to centre housing part 8, and wherein centre housing part 8 is positioned under the upper body 7 and is close to upper casing part 7 along the longitudinal axis 23.From upper body 7 to 8 transition of centre housing part, the girth of container 6 increases and begins to present egg type or oval-shaped cross-sectional plane gradually.The longitudinal axis along container 6 continues downwards, and the girth of container continues to increase, and up to the zone of maximum perimeter 9, the girth of container 6 preferably reduces gradually after this.The maximum perimeter area flag from the transition of middle housing parts 8 to the lower case part 10 of contiguous its closed end 2.

The longitudinal length of upper casing part 7, centre housing part 8 and lower case part 10 changes with the purposes of container 6, the centre housing part is preferably interior preferred from about 1.2: 1 to 6: 1 scope with the ratio of upper casing part length, and better situation is from about 1.75: 1 to 5: 1 scope.The ratio of lower case part and upper casing part length is preferably from about 1: 1 to 3: scope in preferred 1, scope was better from 1.2: 1 to 2.5: 1.

Container 6 along the variation of the cross-sectional plane of its longitudinal length and girth shown in Fig. 2 A to 2F.Each figure is depicted container 6 respectively along the shape of cross section roughly of the hatching A-A to F-F shown in Fig. 1 C.We are unexpected find container upper body girth along the variation of y direction with cosily hold with the improved child of being used for of human engineering and to be used for the container of children and adult's use identical.

Shown in Figure 1A and 1B, the housing 22 of container 6 is by front 11, and 12, the first sides 13, back and second side 14 are formed.The front 11 of container comprises that the back 12 of first groove 15 and container comprises second groove 16.Closed end 2, the first sides 13 of groove and container 6 are adjacent with second side 14.First groove 15 and second groove 16 define first concave surface 17 and second concave surface 18 respectively in the front and back of container.Each groove has a degree of depth 19, shown in Figure 1B.For example the degree of depth of groove 15 is distances from the extended line 21 of the closed end 2 of container 6 to container concave surface 17 on the direction of vertical axes.As shown in figure 13, when container during in inverted orientation, the degree of depth of groove enough allow container 6 by be positioned at container 6 fronts 11 on groove 15 tangent first support 71 and be positioned at container 6 back 12 on tangent second the supporting 72 and hold of groove 16.In fact this support does not contact with the concave surface of container.Because this container can take up and distribute body lotion and the shampoo of toilet cleaning articles for use as being used for shower or bathing pool, especially when container be when wetting, no matter we are surprised to find when the direction of putting upside down still is bevelled steering handle held container, and the degree of depth of these grooves in fact has skidproof effect.

The degree of depth of groove can be required any thickness, and may be decided by occupation mode that container is required and the content that wherein holds.The degree of depth of groove preferably changes with the difference of container position, and better situation is be its innermost at next-door neighbour's container closure end 2 places, and is reducing gradually on nose end 2, contiguous first side 13 and second side 14 vertical.The degree of depth of groove is better preferably from about 2.0mm to 3.4mm from about 2.5 to 2.9mm.Such degree of depth is best as a kind of container with effective antiskid capability is provided, but also will be appreciated that the degree of depth that also can produce other groove, to satisfy concrete needs, also falls within the scope of the present invention.In a most preferred embodiment, groove is the nose end of adjacent vessel not, thereby the external frame of " U " shape is provided for concave surface.Do not have user that groove just can make container length to be free to slide near nose end 1 place, have and user's hand size girth part accordingly to find from the bottom of the concave surface of the most close container closure end 2 to whole substantially first and second concave surfaces of the nose end 1 of container.

The size of the container of the present invention that calculates in ergonomic mode and architectural feature can allow adult and children easily to catch and hold container of the present invention above.These sizes of certainty and the feature of the existing relatively container of container are believed the hobby that the user can be described according to the present invention.

Shown in Figure 1A and Figure 1B, the

side

13,14 and the closed end 2 of concave surface 17 and 18 relative containers are recessed.Although the size of concave surface, shape and geometry dependent change in the required final use of container, first concave surface 17 preferably has identical size, shape and geometry with second concave surface 18.Concave surface, promptly generally is parallel on the direction of the container longitudinal axis and has bigger size on the direction of closed end 2 from the nose end 1 of container; And along first side of container on the direction of second side, promptly be generally perpendicular on the direction of the longitudinal axis and have less size.The length of concave surface is confirmed as promptly putting 30 from that of the groove 15 of the most close container 24 bottoms, to the end face 29 of container upper casing part 7.

Concave surface 17,18 has or substantially for flat or be curved surface 27 and 28.If concave surface is crooked, preferably curve only extends on a dimension, and is straight substantially in other dimension.For example, the container of the present invention shown in Figure 1A and the 1B has concave surface 17,18, and concave surface 17,18 is crooked at its reduced size place, but then is straight at its large-size place substantially.Situation is preferably, and concave surface is on its large-size, and based on the longitudinal length of concave surface, at least about be straight substantially in the distance of its longitudinal length 50%, better situation is to be straight in 65% distance of its longitudinal length at least.We find that the profile of concave surface is particularly suitable for allowing label or ornament are attached on the container by the label that printing or stickup are coated with full adhesives at the container concave part.Under the situation of printing, it stably contacts with print roller not have crooked permission on two dimensions in the whole concave part.Same under the situation of adhesive label, on two dimensions, there is not bending to allow not have gauffer ground to paste sticking label in the whole concave part.

Fig. 3 A and 3B have showed another embodiment of the present invention's container, on the side of this container, have and can select the lateral protrusion 25 or the pit 26 that form, hold the device of container with the finger that a kind of user of reinforcement is provided.Perhaps, the present invention's container can comprise a projection and recessed combination.Although Fig. 3 A and 3B only illustrate the recessed of the projection of side direction and circular arc, but it will be appreciated by those skilled in the art that container of the present invention can have projection, recessed, increase device such as the rubber or the polymeric material model of grip with other or depend on arbitrary shape on the container, the device of size and quantity is to increase the user the strength of held container.

Fig. 4 has showed an embodiment again of container shown in Figure 1A and the 1B, and wherein the volume of container is about half of vessel volume among Figure 1A and the 1B among Fig. 4.

In another embodiment of the present invention, container 6 of the present invention is equipped with one and seals 39, to hold and to discharge the content that is contained in wherein.Those skilled in the art should know at once that the kind/type decided of sealing that is applicable to the present invention in different factors, resembles the kind of content in the container, and content is discharged from required form and offers client's comfort level.

Any known the sealing all in this area can be used with the present invention's container, seals including, but not limited to disclosed those of Wiley.

Under container is used to deposit situation with discharged liquid, seal the convenient cap that the simplest form is an integrative-structure, for therefrom discharging content, this lid must be taken off from container; But, preferably use and need not to take off from container sealing of lid for therefrom discharging content.

An embodiment who seals 39 container who is used for the discharged liquid content is housed, shown in Fig. 5 A, 5B and 5C, has drawn in the drawings Figure 1A that common hinge seals and the container of 1B are housed.Other is suitable seal comprise well known in the art those, but be not limited thereto, comprising: 1) include a main body and the sealing of the lid that can be fully takes off from the main body of sealing; 2) have to be slidably connected to and seal sealing on the main body; 3) not with cover sealing resembles plug-type and pushes sealing of spray formula.These are open in Wiley.

Seal 39 and comprise a housing parts 31 and a cover 32, this cover 32 hingedly is connected on the housing parts by hinge 33.Housing parts 31 comprises a hole (not shown), by this hole, makes content be discharged from.Cover 32 comprises in its lower section a pin (not shown), and this pin is made into certain size and closely cooperates with the hole with housing 31.When cover 32 was in the closed position, pin contacted with housing parts 31, with airtight container, thereby prevented the discharge of its content.Housing parts 31 comprises a selectable pit 34, with by finger being placed in the pit 34 that covers a part of 35, easily opening and seals applying a power below the lid then.

Seal 39 pedestal 36 and the end faces 37 away from pedestal 36 that an adjacent vessel upper casing part arranged.Seal 39 circular perimeters that a basically identical arranged from its pedestal 36 to its end face 37, and this girth equates substantially with the girth of container upper casing part.

Another novel characteristics of the present invention is shown in Fig. 5 A-5C.Sealing 39 preferably has an end face 38, to allow to be inverted storing containers.When the content of container reduces, being inverted storing containers allows the interior residue content of container to accumulate in the nose end of container, rather than at its closed end, thereby the discharge of all the elements thing in the permission container, and eliminated the problem of being detained more thickness content really.The closed end that better situation is a container has with the top of sealing, thereby container both can uprightly be deposited, and can be inverted the flat surface of depositing again.

Another embodiment of the present invention's container is in upright and handstand direction respectively shown in Fig. 6 A and 6B.Seal 40 pedestal 41 and the tops 42 away from pedestal 41 that an adjacent vessel upper casing part arranged.Pedestal 41 has a basic girth for circle, and the girth of this girth and container upper casing part 7 about equally.It is bevelled sealing 40, and the girth that promptly seals increases gradually from pedestal 41 to the end face 42 that seals.So herein sealing is referred to as " back taper " and seals.Tapering can be decided by the final use of required container and required aesthetic effect.Sealing 40 has an end face 43, and this end face 43 makes the container placement of can standing upside down.Big girth at its top is sealed in taper has increased stability when container is squeezed.

In another preferred embodiment, be used for the present invention container seal the valve that can comprise just like shown in Figure 15 A, the embodiment that illustrates that is used for the suitable valve of the present invention's container includes, but are not limited in US Patent 5,439,143,4,749,108 and 4,846,810 disclosed those seal, these seal only do at this as a whole by reference.Open when such valve generally is designed to surpass certain critical pressure, thereby allow content to be discharged from from container, and when subcritical pressure, close, thus the discharge from container of limiting content thing.The minimum value of the critical pressure of valve is decided by the requirement of valve, thereby presents the discharge pressure of maximum when the content of container; Promptly when container was full of, valve will keep the content in the container.The discharge pressure of container contents is decided by the geometric configuration of container and the density of content successively.In force, actual minimum critical pressure is slightly larger than discharge pressure, thereby is used and when not needing content to discharge, adapts to the slight pressure that produces in the container and change when it.The maxim of critical pressure is decided by the requirement that when container is pushed by the user valve opened.In container of the present invention, valve can not only be opened by the adult, and can be opened by more weak children or the elderly of strength on hand.

By the container made from elastomeric material, apply a squeese pressure for the outside of container, just can in container, produce a pressure that surpasses critical pressure, thereby make content be discharged from from container.Stop or fully reducing the pressure that squeese pressure has just reduced internal tank, making it subcritical pressure, thereby valve cuts out and suppress content discharge from container.This characteristics are particularly important under container is often stood upside down situation about using.

Figure 15 A and 15B, Figure 16 A and 16B have showed that the present invention's band back taper seals 85 container, wherein seal 85 and comprise 84 and valves 80 of a lid, lid 84 is hinged with extension component 86 by hinge 83, lid 84 comprise one in its lower section stopper 82, stopper 82 with seal 85 orifice rings of giving prominence to 81 and be meshed.When in use and when being positioned at the position of prepare discharging content, lid 84 is in retrieving position, shown in Figure 15 A.Deposit with transportation in, lid 84 is in detent position, shown in Figure 15 B.When lid 84 was in detent position, lid 84 following stoppers 82 matched with the orifice ring of giving prominence to 81, thereby prevent valve 80 transpositions, and therefrom discharge content.Sealing 85 has a periphery in the bottom 88 of its adjacent vessel upper casing part, and this periphery equates with the girth of container upper casing part.It is bevelled sealing 85, at the girth at its top 87 girth greater than bottom 88.Seal the bigger girth in 85 tops and increased the stability of being inverted the container of depositing.

In the most preferred embodiment shown in Figure 17-27,85 top is sealed in taper a platform 91, one with platform groove 90 concentric and that extend around platform 91, it is concentric with platform 91 and groove 90 to seal sidewall 92 on circumferential, on seal sidewall 92 and extend around the periphery of groove 90, that represents in Figure 27 is more detailed: platform 91 is made of a top table top 113, have with top table top 113 concentric and with the periphery mesa sidewalls 114 and a bottom table top 97 of top table top 113 and lower sealing sidewall 108 one.

On seal sidewall 92 and extend to the bottom of groove 90 from the end face 93 that seals, perhaps in the embodiment of no groove, extend to top table top 113.Usually, seal the height A (measuring) of sidewall 92 on sealing along the longitudinal axis, as shown in figure 18, its scope (making radix with the whole length H that seals) as shown in figure 21, can from greater than 0% to less than 100%, situation is from greater than 20% to less than 90% preferably, the best be from greater than 50% to less than 70%.Although on seal sidewall 92 thickness can change with required size of sealing, time of sealing required strength under shock and sealing from mold appropriate cooling, usually its thickness can change to about 2.03mm (0.080 inch) scope at about 0.38mm (0.015 inch), situation is interior variation of scope from about 0.76mm (0.03 inch) to about 1.52mm (0.06 inch) preferably, and the best is interior the variation from about 1.02mm (0.04 inch) to about 1.27mm (0.05 inch) scope.

Although the width of groove 90 depends on required size of sealing, seal required strength under shock, seal time of appropriate cooling from mold and required berm width and change, but the width of groove 90 width general and platform 97 is inversely proportional to, and best width less than platform 97.Better situation is a groove 90 along the width of determining on upper mounting plate surface 91 at least about 1.65mm (0.065 inch).Along determining of upper mounting plate surface 91.Figure 29 C and 29D have showed 85 two embodiment of sealing of the groove 90 that has different in width.

In a most preferred embodiment, groove 90 has at least one hole 94, be fixed on the container when sealing, and when being fixed on the shoulder 5 of container, this hole 94 makes water and/or remaining content discharge from groove 90.This feature has prevented that the gathering of resistates on the table top 91 and/or the resistates of pollution from flowing into container.

In a most preferred embodiment as shown in figure 23, platform 91 is recessed from the end face 93 that seals sidewall 92.The degree of depth of the platform that seals recessed 200, as shown in figure 18, for along the longitudinal axis from top table top 113 to the distance A of the end face 93 that seals sidewall 92.Although the degree of depth of platform recessed 200 can be dependent on required size of sealing, seal required strength under shock, the required distance of required output mechanism running changes with the time quantum that is used to seal appropriate cooling on mold, but with the overall height H that seals as radix, this degree of depth can be approximately greater than 0% to less than changing in 100% the scope, situation is to change in from 20% to 80% the scope preferably, and the best is from 30% to 50%, as shown in Figure 1.Seal 85 in a better taper and distribute among the embodiment seal as one, this degree of depth can make required distribution device again closing organ operation remainder then be lower than end face 93 to recessed, see Figure 17.
