Description

Container Cover and Container Cover Stack {CONTAINER LID AND CONTAINER LID STACK}

The present invention relates to a container lid and a container lid stack capable of opening a drinking appliance in the lid by pulling the pull tab, and then leaving the pull tab attached to the lid.

Conventionally, pull-top cans are used for beverage containers, such as coffee, juice, and a drink. The pull-top can is switched from the type in which the pull tab detaches from the container body to a type in which the pull tab does not detach from the container in order to prevent scattering of the pull tab at present (see Patent Document 1, for example).

In this type of pull-top type in which the pull tab does not detach from the container, since the pull tab is made of a metallic material, the closing portion can be press-fitted and maintained as it is, so that the opening can be maintained. On the other hand, since it consists of metal materials, in a system (form) which press-fits a closed part and hold | maintains an opening part, it is difficult to obtain a comparatively large opening structurally.

In particular, according to the contents of recent beverages, there is a mixture of solids (jelly or tapioca, etc.) with a liquid phase, and when drinking directly, it is difficult to drink the contents unless the opening is large.

Moreover, there exists a container cover which consists of a synthetic resin which does not have shape retention, and can hold large the opening used as an intake which follows a drinking utensil or a drink, without removing a pull tab from a container cover (for example, refer patent document 2).

This type of container lid, in which the pull tab does not detach from the container, is designed to lock the pull tab further away so that it is easy to open the closure of the large drinking utensil to open the closure of the large drinking utensil, so as to be opened with a relatively weak force. The remaining length of the closed portion becomes long, and the opening operation cannot be facilitated, and it is difficult to open in a short time. In addition, the stability of the pull tab in appearance after opening of the pull tab, lock stability of the lock portion, and resealability (not completely sealing) is poor.

In addition, as the container lid of this kind, a drinking tool forming portion for forming a drinking implement is set on the top wall, and a straight bent line is formed at a part of the boundary between the drinking appliance forming portion and the other portion. The curved cutting line is formed in each, the support leg stands up from the point which distanced from the bend line in the drinking instrument formation part, the circular pull tab spreads toward the direction of a bending line from the upper end of the support leg, and is normal It is known that the pull tab is configured to allow the pull tab to engage the joining bar, with the joining bar standing up between the wall outer periphery and the bending line, the cut line being cut and the drinking tool forming portion bent along the bending line (eg, See Patent Document 3).

In this drinking container, the diameter of the pull tab is so large that it is not compared with the diameter of a coupling rod. Therefore, in a state where the pull tab is engaged with the engaging bar, the pull tab can move freely within the range allowed by the difference in diameter between the pull tab and the engaging bar. As a result, engagement of the pull tab and the engaging bar is easy to be released. In addition, when the pull tab moves, the bending angle of the drinking implement forming portion changes with this, and the opening degree of the drinking appliance cannot be kept constant. If a part of the drinking utensil is blocked by the drinking utensil forming portion, there is a fear that the drink becomes difficult to drink.

Patent Document 1: Japanese Patent Application Laid-Open No. 2004-210318 Patent Document 2: Japanese Patent Application Laid-Open No. 2006-103782 Patent Document 3: Japanese Patent Application Laid-Open No. 09-124035

An object of the present invention is to provide a drinking container which can reliably maintain the opening state of the drinking appliance. In detail, even in a container cover made of a synthetic resin having no shape retention, it is possible to maintain a relatively large opening to be an inlet following a drinking utensil or a beverage without detaching the pull tab from the container cover, and is easy to open and easy to drink. A container cover which can be resealable is provided. Furthermore, it aims at providing the stack of this container cover.

The container cover made of synthetic resin according to the present invention includes a top wall and a circumferential wall vertically descending from an outer circumference of the top wall, and a drinking implement forming portion for forming a drinking appliance is set on the top wall, A straight bent line is formed at a part of the boundary between the formation part and the other part, and a bent cut line is formed at the other part, and the support leg stands up from a point distanced from the bent line in the drinking tool forming part. The pull tab extends from the upper end of the support leg toward the bend line, the engaging tab is provided on the lower face of the pull tab, the flange is provided on the outer surface of the circumferential wall, the cutting line is cut, and the drinking tool forming portion is cut along the bending line. In the state bent in the direction which overlaps with the part adjacent to a curve, the engagement protrusion is comprised so that it may couple to the flange from the lower side.

In the drinking container according to the present invention, even when the drinking tool forming portion tries to return to the direction of blocking the drinking tool by spring back force while the engaging projection is engaged with the flange, the force acts to increase the coupling force of the engaging projection to the flange. Therefore, the drinking appliance forming portion does not return, and there is no fear that the drinking appliance is clogged by the drinking appliance forming portion.

In addition, since the cutting operation of the cutting line, the bending operation along the bending line, and the engaging operation of the engaging projection to the flange can be performed by the pulling operation in one direction of the pull tab, the opening operation can be facilitated with a simple structure. Also, it can be opened in a short time.

Further, in the state where the engaging projection is coupled to the flange from the lower side, the bent portions are respectively formed in the base portion of the drinking implement forming portion and the base portion of the support leg, and by the spring back force generated in both base portions, If the path leading to it is in tension, the engagement of the engaging projection to the flange is maintained so as not to be released.

In addition, a concave accommodating portion is provided in an area adjacent to the drinking ball forming portion with the bend line at the top wall interposed therebetween, and a cutting line is cut and the drinking tool forming portion overlaps the portion adjacent to the bending line along the bending line. In the state bent in the state, if the drinking apparatus forming unit is configured to be accommodated in the receiving unit, the entire drinking apparatus forming unit is completely collapsed in the housing unit, so that the drinking apparatus is opened greatly, and the nose of the drinking person It does not touch the tool forming part.

The top wall has a circular shape, and the bending line is orthogonal to the reference line passing through the center of the top wall and dividing the drinking tool forming portion, and the pull tab has a circular ring shape and is parallel to the drinking ball forming portion. If the engaging projections are located at two straight lines passing through the center of the pull tab and orthogonal to the reference line, the two engaging projections are joined to the flange at equal intervals from the reference line on both sides with the reference line interposed therebetween. State can be maintained reliably.

If the engaging surface perpendicular to the lower surface of the pull tab is formed on the supporting leg direction side of the engaging projection, and the engaging guide surface is formed on the opposite side to the gradient of the lower surface of the pull tab, the engaging guide surface at the time of engaging the engaging projection. The guiding projections can smoothly ride over the flanges while being guided, and a secure engagement is ensured by the mating surfaces after they have been taken over.

In addition, if a drinking guide wall is provided between the top wall outer periphery and the drinking implement forming portion, which covers the drinking implement forming unit from the outside of the top wall in the radial direction, the mouth of the drink is followed by the drinking guide wall. The spilled beverage is guided to the drinker's mouth without overflowing by the guide wall, so that the beverage can be smoothly drunk from the drinking apparatus after the opening.

Moreover, when ultrasonically sealing a flange to a container main body, when the vibration of an ultrasonic seal is transmitted to a drinking opening formation part, a pinhole may generate | occur | produce in a drinking opening formation part, but a drinking guide wall prevents this.

In the case where a plurality of container lids are stacked, an upper small diameter portion and a lower large diameter portion are formed on the outer surface of the peripheral wall of each container lid with the ends interposed therebetween. If the lower large diameter part of the upper container cover is fitted to the upper small diameter part of the lower container cover, and supports the lower end of the lower large diameter part of the upper container cover with the end of the lower container cover, the upper and lower two container covers Since the circumferential walls of the two are fitted together, the container cover can be prevented from being easily dispersed.

When supplying the container cover to the charger, by keeping the plurality of container covers stacked, no large-scale and special supply device is required.

Moreover, if a pair of acid is formed in the both sides across the drinking-port formation part of each container cover, and the stack guide surface of the same surface as the outer side of the lower diameter part of each container cover is formed in the outer surface of each mountain, a container cover, At the time of stacking, the container cover can be smoothly stacked by the stack guide surface.

According to this invention, a drinking instrument can be opened to a container cover, and can be reliably held in the opening state.

In the following description, the front and back means the side which becomes the drinking tool of a beverage container (front side shown by arrow A of FIGS. 1-3), and the opposite side to this is the back, and the left and right columns are the left and right sides when it sees from the back. It will be called left and right.

In FIG. 1, the beverage container before opening of a drinking implement is shown in FIG. 2, and the beverage container after opening of a drinking apparatus is shown, respectively.

The beverage container includes a cup-shaped container main body 11 and a container lid 12 covering the opening of the container main body 11. Both the container main body 11 and the container lid 12 are integrally molded by thermoplastic synthetic resin. In the case where the container body 11 is molded into a support body laminate instead of the thermoplastic synthetic resin, a thermoplastic synthetic resin film layer is required on the surface of the support body laminate.

The opening flange 21 is provided in the opening of the container main body 11.

The container cover 12 includes a flat circular top wall 31 and a circumferential wall 32 that vertically descends from the outer circumference of the top wall 31.

In FIG. 3, the reference line Ls extending in the front-rear direction and the partition line Ld extending in the left-right direction are set. The reference line Ls and the partition line Ld are orthogonal to each other and both pass through the container center Co.

In the container lid 12, a drinking implement forming portion 41 for opening to form a drinking appliance is set. The drinking implement formation part 41 is an area | region enclosed by the dashed line 42 shown in FIG. 3, and spreads toward the outer periphery of the top wall 31 forward from the part containing container center Co, and centers the container center Co ) Is a base portion, and the front and rear elongated tongue region having a portion near the outer circumference of the top wall 31 as the tip portion. In addition, the drinking implement forming portion 41 is bisected left and right by the reference line Ls.

A straight bent line 43 is formed at a part of the boundary between the drinking implement forming portion 41 and the other part, and a U-shaped cut line 44 is formed at the other part. The bending line 43 extends in parallel with this partition line and is bisected by the reference line Ls at the point which crossed back from the partition line Ld by the distance (epsilon). The cutting line 44 extends forward and inverts from the right end of the bend line 43, and then extends backward to reach the left end of the bend line 43.

As shown in FIG. 4, the bending line 43 consists of the bending thin part obtained by forming the bending groove 45 of the semicircular arc cross section on the back surface of the top wall 31. As shown in FIG. 4 and 5, the cutting line 44 is formed of a cutting thin portion obtained by forming a cutting groove 46 having a V-shaped cross section on the rear surface of the top wall 31.

The rear opening recessed accommodating part 47 is unfolded adjacent to the drinking-form formation part 41 adjacent to this. The storage part 47 has almost the same shape as the drinking implement formation part 41 which makes the bending line 43 the line symmetry axis.

The support leg 51 stands up from the point where the reference line Ls and the cutting line 44 crossed in the drinking implement formation part 41. FIG. A circular pull tab 52 is connected to the upper end of the support leg 51. The pull tab 52 is integrated with the upper end of the support leg 51 at the front end of the circumferential direction thereof and extends backward from the upper end of the support leg 51 in parallel with the drinking implement forming portion 41. Two coupling protrusions 53 are provided on the lower surface of the pull tab 52. Both engaging protrusions 53 are respectively located on the dividing line Lr which passes through the center of the pull tab 52, and orthogonally crosses with the reference line Ls. An engaging surface 54 orthogonal to the lower surface of the pull tab 52 is provided at the front side of each of the engaging projections 53, and an engaging guide surface 55 forming a gradient of the lower surface of the pull tab 52 and the rearward upward at the front end thereof. Formed.

The vertical drinking guide wall 61 stands up between the front end of the drinking implement forming portion 41 and the outer circumference of the top wall 31 facing this. The drinking guide wall 61 is a semi-circular arc shape with the opening side facing rearward in plan view, and covers the tip end portion of the tongue of the drinking implement forming portion 41 from the front side.

A pair of peaks 62 are formed on both left and right sides with the drinking implement forming portion 41 and the storage portion 47 interposed therebetween. Each peak 62 forms part of an annular shape extending along the outer circumference of the top wall 31 in plan view. The concave portions forming the torus of the two mountains 62 face each other.

On the outer surface of the circumferential wall 32, an upper small diameter portion 71 and a lower large diameter portion 72 are provided with the end 73 interposed therebetween. A stack guide surface 74 is formed on the outer surface of the upper small diameter portion 71. The stack guide surface 74 becomes the same plane as the strip | belt-shaped part extended along the lower edge of the outer surface of each peak 62, and is extended over the perimeter of the upper small diameter part 71. As shown in FIG. A tapered stack centering surface 75 having a thin tip is formed above the stack guide surface 74 on the outer surface of each peak 62.

In the middle height of the outer surface of the lower large diameter part 72, the outer periphery flange 81 superimposed on the upper surface of the opening flange 21 and provided is provided.

The opening order of the drinking equipment is as follows. When the pull tab 52 is grasped with a finger and stretched backward, the cutting line 44 is gradually cut from the front side toward the rear side. When the whole cutting line 44 is cut | disconnected, a drinking implement will open there. Thereafter, when the pull tab 52 is pulled back to the rear and the cut drinking tool forming part 41 is pushed down, the drinking tool forming part 41 falls down and is bent along the bending line 43.

As shown in Fig. 6A, the drinking implement forming portion 41 is bent until it almost overlaps the bottom surface of the receiving portion 47, and almost the whole thereof is housed in the storing portion 47, and the drinking appliance is formed. When the pull tab 52 is orthogonal to the part 41, the engaging guide surface 55 of both engaging projections 53 is in contact with the outer circumferential flange 81 from the upper side. In this state, when the pull tab 52 is pushed down, as shown in FIG.6 (b), the front-end | tip of both engaging protrusion 53 passes over the outer periphery flange 81 and the opening flange 21, and a mating surface 54 is coupled from the lower side to the outer peripheral flange 81 via the opening flange 21. Engaging points of both engaging projections 53 to the outer circumferential flange 81 are both sides thereof with the reference line Ls interposed therebetween, and are almost the same point as the radius of the pull tab 52 from the reference line Ls.

It should be noted here that the engaged state of the pull tab 52 shown in Fig. 6B is in a tensioned state, and the engaged state is not inadvertently released. In other words, there is no looseness in the transmission path of the spring force from the bend line 43 to the engagement protrusion 53. That is, the first bent portion is formed in the base portion of the drinking apparatus forming unit 41 so that the drinking apparatus forming unit 41 and the receiving unit 47 overlap, and the pull tab 52 parallel to the drinking apparatus forming unit 41 is formed. The second bent portion is formed in the base portion of the support leg 51 so as to be orthogonal to the drinking tool forming portion 41, whereby the engagement state is not released by the spring back force generated in the first and second bent portions. Is being kept.

When a drink is drink from the drinking container which opened the drinking utensil, the lower lip of the drink is put on the outer surface of the drinking guide wall 61, and the drinking container is inclined to drain the drink from the drinking utensil. The spilled beverage flows on the inner surface side of the drinking guide wall 61 and flows smoothly to the drinking mouth without overflowing.

In the manufacturing process of the beverage container, the container cover 12 is supplied to the container body 11 filled with the contents. The opening flange 21 and the outer peripheral flange 81 which overlap with each other are sealed by an ultrasonic seal machine. In this case, when the vibration of the ultrasonic seal machine is transmitted to the cutting line 44, there is a fear that pinholes are generated in the cutting line 44. In particular, the portion near the outer circumference of the top wall 31 in the cutting line 44 is highly concerned, but since the portion is covered with the drinking guide wall 61, there is no fear of pinholes in the portion. .

When supplying the container cover 12 to the container main body 11, the some container cover 12 is stacked. As shown in FIG. 7, in the upper and lower adjacent container cover 12, the lower large diameter part 72 of the upper container cover 12 is the upper small diameter part 71 of the lower container cover 12. As shown in FIG. The lower end of the lower large diameter portion 72 of the upper container lid 12 is supported by the end 73 of the lower container lid 12. When stacking both container lids 12, the stacking operation is smooth while the lower large diameter portion 72 of the upper container lid 12 is centered by the stack centering surface 75 of the lower container lid 12. Is done.

Moreover, in the state in which the two container lids 12 were stacked, the stage 73 of the upper container lid 12 pressed against the top surface of the peak 62 of the lower container lid 12. Thus, the stack of the container lid 12 is prevented from rattling.

In the above embodiment, the top wall 31 has a circular shape, but is not limited thereto, and may be, for example, elliptical or square. In addition, although the pull tab 52 is shown to be circular ring-shaped, it may be elliptical, square, or triangular, for example, Furthermore, it may not be ring-shaped or it may be a tongue shape. The number of the engaging projections 53 may be 1 or 3 or more, and as long as it can couple | bond with the opening flange 21 and the outer peripheral flange 81, the shape and position are not limited.

The drinking container which concerns on this invention is suitable for achieving opening of a drinking implement to a lid | cover by tension of a pull tab, and after leaving a pull tab affixed to a lid | cover.
